 WHEREAS,
Wexford has extensive knowledge and experience with respect to managing public and private businesses, capital markets transactions, financing transactions, long range planning and business development and other matters that are significant to the
future business and operations of the Company; and 
 WHEREAS, the Company desires to benefit from Wexford’s expertise and has
requested that Wexford provide assistance and advice to the Company from time to time with respect to certain financial and strategic matters related to the business and affairs of the Company and its subsidiaries; and 

WHEREAS, Wexford has agreed to the Company’s request on the terms and conditions specified herein. 

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and other good and valuable consideration, the receipt

Section 2. Term; Termination. 

(a) Term. This Agreement shall commence on the closing date of the Company’s initial public offering and shall terminate
on the second anniversary thereof (the “Initial Term”). Upon expiration of the Initial Term, this Agreement shall automatically continue for additional one-year periods unless terminated in writing by either party at least ten
days prior to the expiration of the then current Term (each extension period being referred to herein as the “Extension Term,” and together with the Initial Term, the “Term”).

30 days’ prior written notice to the other party. In the event of termination by the Company, the Company shall be obligated to pay all amounts due to Wexford through the remaining Term of the Agreement. The provisions set forth in
Section 5 of this Agreement shall survive any termination of this Agreement. 

 Section 3. Advisory Services. 

(a) Wexford shall provide general financial and strategic advice to the Company and its subsidiaries (the “Services”), in
each case, as the Company shall reasonably request from Wexford. The Services shall not extend to the day-to-day business or operations of the Company and shall not include any services provided by officers or employees of Wexford in their
capacity as directors of the Company. If requested to provide Services, Wexford shall devote such time to any such request as Wexford shall deem, in its sole discretion, necessary. Such Services, in Wexford’s sole discretion, shall be
rendered in person or by telephone or other communication. Wexford shall have no obligation to the Company as to the manner of rendering the Services hereunder, and the Company shall not have any right to dictate or direct the details of the
Services rendered hereunder. 
 (b) Wexford shall perform all services as an independent contractor to the Company and not as an
employee, agent or representative of the Company. Wexford shall have no authority to act for or to bind the Company without its prior written consent. Nothing in this Agreement is intended nor shall be deemed to create any partnership,
agency or joint venture relationship by or between the parties. 
 (c) This Agreement shall not prohibit, restrict or limit in any
manner Wexford or any of its partners or affiliates or any director, officer, partner or employee of Wexford or any of its partners or affiliates (collectively, “Wexford Persons”) from engaging in other activities, whether or not
competitive with any business of the Company or any of its respective subsidiaries or affiliates. This Agreement shall not require Wexford or any Wexford Person to make available to the Company any investment or investment opportunity about
which Wexford or any Wexford Person shall become aware. 
 (d) In the event the Company is dissatisfied in any manner with the Services
provided by Wexford hereunder or with Wexford’s performance under this Agreement, the Company’s sole remedy shall be to terminate this Agreement. Under no circumstances shall the Company have any claim for damages against Wexford or
any Wexford Person arising out of or relating to this Agreement. 
 Section 4. Compensation. 

(a) Advisory Fee. As consideration for the Services provided by Wexford hereunder, the Company agrees to pay to Wexford an
annual fee in the amount of $500,000 payable in advance in equal monthly installments, on the first business day of each month during the Term and prorated for any partial calendar month. 

(b) Expenses. Upon presentation by Wexford to the Company of such documentation as may be reasonably requested by the
Company, the Company shall reimburse Wexford for all reasonable out-of-pocket expenses, including, without limitation, reasonable legal fees and expenses, and other disbursements incurred by Wexford or any Wexford Person in the performance of
Wexford’s obligations hereunder. 
 (c) Additional Services. The Company may request that Wexford provide services in
addition to the Services (“Additional Services”), including without limitation, services relating to 

  
 2 

 
proposed acquisitions or divestitures, debt or equity financings, or other transactions. In the event Wexford agrees to provide such Additional Services, the Company shall pay Wexford an
additional market-based fee for such Additional Services, which fees shall be approved by the audit committee of the Company’s board of directors. 

(d) Non-Exclusive. Nothing in this Agreement shall have the effect of prohibiting Wexford or any of its affiliates from
receiving from the Company or any of its subsidiaries or affiliates any other fees. 
 Section 5. Indemnification. 

(a) The Company will indemnify and hold harmless Wexford and each Wexford Person (each such person, an “Indemnified
Party”) from and against any and all losses, claims, damages, liabilities, costs and expenses, whether joint or several (the “Liabilities”), related to, arising out of or in connection with this Agreement or the Services or
Additional Services contemplated by this Agreement or the engagement of Wexford pursuant to, and the performance by Wexford of the Services or Additional Services contemplated by, this Agreement, whether or not pending or threatened, whether or not
an Indemnified Party is a party, whether or not resulting in any liability and whether or not such action, claim, suit, investigation or proceeding is initiated or brought by or on behalf of the Company. The Company will reimburse any
Indemnified Party for all reasonable costs and expenses (including attorneys’ fees and expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any action, claim, suit,
investigation or proceeding for which the Indemnified Party would be entitled to indemnification under the terms of the previous sentence, or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party
thereto. The Company will not be liable under the foregoing indemnification provision with respect to any particular Liability of an Indemnified Party solely to the extent that such is determined by a court, in a final judgment from which no
further appeal may be taken, to have resulted primarily from the gross negligence or willful misconduct of such Indemnified Party. The attorneys’ fees and other expenses of an Indemnified Party shall be paid by the Company as they are
incurred upon receipt of an agreement by or on behalf of the Indemnified Party to repay such amounts if it is finally judicially determined that the Liabilities in question resulted primarily from the gross negligence or willful misconduct of such
Indemnified Party. 
 (b) The Company acknowledges and agrees that the Indemnified Parties have certain rights to indemnification
and/or insurance provided by Wexford and certain of its affiliates and that such additional rights to indemnification and/or insurance are intended to be secondary to the primary obligation of the Company to indemnify the Indemnified Parties
hereunder. The Company’s obligations to provide indemnification hereunder shall not be limited in any manner by the availability of such additional indemnification and/or insurance that may be available to the Indemnified Parties. 

Section 6. Accuracy of Information. 

The Company shall furnish or cause to be furnished to Wexford such information as Wexford believes reasonably appropriate in connection with
providing the services contemplated by this Agreement (all such information so furnished, the “Information”). The Company

verification.

 The foregoing notwithstanding, a transaction will not constitute a Change in Control if (1) its sole purpose
is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the Persons who held the Company’s securities immediately before such transaction; (2) it
constitutes an initial public offering or a secondary public offering that results in any security of the Company being listed (or approved for listing) on any securities exchange or designated (or approved for designation) as a security on an
interdealer quotation system; (3) it constitutes a change in Beneficial Ownership that results from a change in ownership of an existing stockholder; or (4) solely because 50% or more of the total voting power of the Company’s then

directly or indirectly by the stockholders of the Company in substantially the same proportion as their ownership of stock in the Company immediately before such acquisition. 

For purposes of determining the occurrence of a Change in Control under this Section 2(i), the term “Person” shall include one or more

(o) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an
Employee, Director or Consultant, is not interrupted or terminated. The Participant’s Continuous Service will not be deemed to have terminated merely because of a change in the capacity in which the Participant renders service to the Company or
an Affiliate as an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, so long as there is no interruption or termination of the Participant’s Continuous Service. For example, a change in
status from an Employee of the Company to a Consultant of an Affiliate or a Director will not constitute an interruption of Continuous Service. The Administrator or its delegate, in its sole discretion, may determine whether Continuous Service will

purposes of determining the term of an Incentive Stock Option pursuant to Section 6(a) hereof, the term Disability has the meaning ascribed to it under Code Section 22(e)(3). The Administrator will determine whether an individual
has a Disability under procedures established by the Administrator. Except in situations where the Administrator is determining Disability within the meaning of Code Section 22(e)(3) for purposes of the term of an Incentive Stock Option

determined below. 
 (i) On any date on which shares of Common Stock are readily tradable on an Established Securities Market, if the Common
Stock is admitted to trading on an exchange or market for which closing prices are reported on any date, Fair Market Value may be determined based on the last sale before or the first sale after the Date of Grant of an Award, the closing price on
the trading day before the Date of Grant of an Award or on the Date of Grant; or may be based on an average selling price during a specified period that is within 30 days before or 30 days after the Date of Grant of an Award, provided that the

Section 401(a)(28)(C) and the regulations promulgated thereunder as of a date that is no more than 12 months before the relevant transaction to which the valuation is applied (for example, an Option’s Date of Grant) and such determination
will be conclusive and binding on all persons.

Section 7(c)(i).

	3.	Administration. 

 (a) Administration by Board. The Plan will
be administered by the Board unless and until the Board delegates administration to a Committee, as provided in Section 3(e). 

(b) Authority of Administrator. The Administrator will have the power and authority to select Participants and grant Awards
pursuant to the terms of the Plan. 
 (c) Specific Authority. In particular, the Administrator will have the authority to:
(i) construe and interpret the Plan and apply its provisions; (ii) promulgate, amend, and rescind rules and regulations relating to the administration of the Plan; (iii) authorize any person to execute, on behalf of the Company, any
instrument required to carry out the purposes of the Plan; (iv) delegate its authority to one or more Officers of the Company with respect to Awards that do not involve Covered Employees or Insiders, provided such delegation is pursuant to a
resolution that specifies the total number of shares of Common Stock that may be subject to Awards by such Officer and such Officer may not make an Award to himself or herself; (v) determine when Awards are to be granted under the Plan;
(vi) select, subject to the limitations set forth in the Plan, those Participants to whom Awards will be granted; (vii) determine the number of shares of Common Stock to be made subject to each Award; (viii) determine whether each
Option is to be an Incentive Stock Option or a Nonstatutory Stock Option; (ix) prescribe the terms and conditions of each Award, including, without limitation, the Strike Price or Exercise Price and medium of payment, vesting provisions and
Right of Repurchase provisions, and to specify the provisions of the Award Agreement relating to such grant or sale; (x) subject to restrictions applicable under Section 12(d), amend any outstanding Awards, including for the purpose
of modifying the time or manner of vesting, the purchase price, Exercise Price or Strike Price, or the term of any outstanding Award; provided, however, that if any such amendment impairs a Participant’s rights or increases a
Participant’s obligations under his or her Award, such amendment shall also be subject to the Participant’s consent (for the avoidance of doubt, a cancellation of an Award where the Participant receives a payment equal in value to the Fair
Market Value of the vested Award or, in the case of vested Options or SARs, the difference between the Fair Market Value of the Common Stock subject to an Option or SAR and the Exercise Price or Strike Price, will not constitute an impairment of the
Participant’s rights that requires consent); (xi) determine the duration and purpose of leaves of absences that may be granted to a Participant without constituting termination of their Continuous Service for purposes of the Plan, which
periods will be no shorter than the periods generally applicable to Employees 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 9 

 
under the Company’s employment policies or as required under applicable law; (xii) make decisions with respect to outstanding Awards that may become necessary upon a Change in Control
or an event that triggers capital adjustments; and (xiii) to exercise discretion to make any and all other determinations that it may determine to be necessary or advisable for administration of the Plan. 

(d) Decisions Final. All decisions made by the Administrator pursuant to the provisions of the Plan will be final and binding on
the Company and the Participants, unless such decisions are determined by a court having jurisdiction to be arbitrary and capricious. 
 (e)
The Committee. 
 (i) General. The Board may delegate administration of the Plan to a Committee or Committees of one or
more members of the Board, and the term “Committee” will apply to any person or persons to whom such authority has been delegated. If administration is delegated to a Committee, the Committee will have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in the Plan to the Board or the
Administrator will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, consistent with the provisions of the Plan, as the Board may adopt. The Board may abolish the Committee at any time and revest in the Board
the administration of the Plan. The members of the Committee will be appointed by and serve at the pleasure of the Board. The Board may increase or decrease the size of the Committee, add additional members to, remove members (with or without cause)
from, appoint new members in substitution therefor, and fill vacancies, however caused, in the Committee. The Committee shall act pursuant to a vote of the majority of its members or, in the case of a Committee comprised of only two members, the
unanimous consent of its members, whether present or not, or by the written consent of the majority of its members and will keep minutes of all of its meetings. Subject to the limitations prescribed by the Plan and the Board, the Committee will
establish and follow such rules and regulations for the conduct of its business as it may determine to be advisable. 
 (ii) Committee
Composition when Common Stock is Registered. Whenever the Common Stock is required to be registered under Section 12 of the Exchange Act, in the discretion of the Board, a Committee may consist solely of two or more Non-Employee Directors
who are also Outside Directors. The Board will have discretion to determine whether or not it intends to comply with the exemption requirements of Rule 16b-3, Code Section 162(m), or both. If, however, the Board intends to satisfy such
exemption requirements, with respect to Awards to any Covered Employee and with respect to any Officer, Director or other Insider, the Committee must at all times consist solely of two or more Non-Employee Directors who are also Outside Directors.
Within the scope of such authority, the Board or the Committee may (i) delegate to a committee of one or more members of the Board who are not Outside Directors the authority to grant Awards to eligible persons who are either (A) not then
Covered Employees and are not expected to be Covered Employees at the time of recognition of income resulting from such Award or (B) not persons with respect to whom the Company wishes to 

 

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 10 

 
comply with Code Section 162(m) or (ii) delegate to a committee of one or more members of the Board who are not Non-Employee Directors the authority to grant Awards to eligible persons
who are not then Insiders. Nothing herein is intended to create an inference that an Award is not validly granted under the Plan in the event Awards are granted under the Plan by a committee of the Board that does not at all times consist solely of
two or more Non-Employee Directors who are also Outside Directors. 
 (f) Indemnification. In addition to such other rights of
indemnification as they may have as Directors or members of the Committee, and to the extent allowed by applicable law, the Company shall indemnify the Administrator against the reasonable expenses, including attorney’s fees, actually incurred
in connection with any action, suit or proceeding or in connection with any appeal therein, to which the Administrator may be party by reason of any action taken or failure to act under or in connection with the Plan or any Award granted under the
Plan, and against all amounts paid by the Administrator in settlement thereof (subject, however, to the Company’s approval of the settlement, which approval the Company shall not unreasonably withhold) or paid by the Administrator in
satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it is adjudged in such action, suit or proceeding that the Administrator did not act in good faith, did not act in a manner that such person
reasonably believed to be in the best interests of the Company, or in the case of a criminal proceeding, had no reason to believe that the conduct complained of was lawful; provided, however, that within 60 days after institution of
any such action, suit or proceeding, such Administrator or Committee member shall, in writing, offer the Company the opportunity at its own expense to handle and defend such action, suit or proceeding. 

 

	4.	Shares Subject to the Plan. 

 (a) Share Reserve. Subject to
the provisions of Section 11(a) relating to adjustments upon changes in Common Stock, the shares that may be issued pursuant to Awards will consist of the Company’s authorized but unissued Common Stock, and the maximum aggregate
amount of such Common Stock that may be issued upon exercise of all Awards under the Plan will not exceed             shares of Common Stock (subject to adjustment as provided in
Section 11(a)), all of which may be used for Incentive Stock Options or any other Awards. Awards for fractional shares of Common Stock may not be issued under the terms of the Plan. 

(b) Reversion of Shares to the Share Reserve. If any Award for any reason expires or otherwise terminates, in whole or in part,
the shares of Common Stock not acquired under such Award will revert to and again become available for issuance under the Plan. If the Company reacquires shares of Common Stock issued under the Plan pursuant to the terms of any forfeiture provision,
including the Right of Repurchase of unvested Common Stock under Section 10(f)(i), such shares will again be available for purposes of the Plan. Each share of Common Stock subject to any Award granted hereunder will be counted against
the share reserve set forth in Section 4(a) on the basis of one share for every share subject thereto. Notwithstanding anything herein to the contrary, shares of Common Stock used to pay the required Exercise Price or tax obligations, or
shares not issued in connection with settlement of an Option or SAR or that are used or withheld to satisfy tax obligations of the Participant will not 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 11 

 
be available again for other Awards under the Plan. Awards or portions thereof that are settled in cash and not in shares of Common Stock will be counted against the foregoing maximum share
limitations. 
 (c) Source of Shares. The shares of Common Stock subject to the Plan may be authorized but unissued Common
Stock or reacquired Common Stock, bought on the market, pursuant to any forfeiture provision, Right of Repurchase or otherwise. 
  

	5.	Eligibility. 

 (a) Eligibility for Specific Awards. Incentive
Stock Options may be granted only to Employees. Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. 

(b) Ten Percent Stockholders. An Incentive Stock Option Ten Percent Stockholder granted to a Ten Percent Stockholder must have
an Exercise Price no less than 110% of the Fair Market Value of the Common Stock at the Date of Grant and must not be exercisable after the expiration of five years from the Date of Grant. 

(c) Section 162(m) Limitation. 

(i) Subject to the provisions of Section 11(a) relating to adjustments upon changes in the shares of Common Stock, no Person will
be eligible to be granted Awards (including, without limitation, Options, SARs and hypothetical Common Stock units) covering more than             shares in the aggregate during any
calendar year. 
 (ii) Section 5(c)(i) shall not apply before the first date on which any class of the Company’s common
equity securities is required to be registered under Section 12 of the Exchange Act, determined based solely on whether, as of the last day of its taxable year, the Company is subject to the reporting obligations of Section 12 of the
Exchange Act (other than due to a voluntary registration). 
 (iii) On and after the first date on which any class of the Company’s
common equity securities is required to be registered under Section 12 of the Exchange Act, Section 5(c)(i) shall not apply to Options, SARs or Awards of Restricted Stock until: 

(1) the earliest of: (i) the first material modification of the Plan (including any increase in the number of shares of Common Stock
reserved for issuance under the Plan in accordance with Section 4(a)); (ii) the issuance of all of the shares of Common Stock reserved for issuance under the Plan; (iii) the expiration of the Plan; or (iv) the first
meeting of stockholders at which Directors are to be elected that occurs after the close of the third calendar year following (x) the calendar year in which the Company’s initial public offering (within the meaning of
Section 12(f)(1)(G) of the Exchange Act) occurs, or (y) if the Company first becomes subject to the registration requirements of Section 12 of the Exchange Act without an initial public offering, the first calendar year following the
calendar year in which the Company is first required to register any equity security under Section 12 of the Exchange Act; or 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 12 

 (2) such other date required by Code Section 162(m) and the rules and regulations
promulgated thereunder. Notwithstanding the foregoing, if the Company first becomes subject to Section 12 of the Exchange Act in connection with an initial public offering, then this Section 5(c)(iii) will apply only to the extent
that the prospectus covering the initial public offering discloses information concerning the Plan in satisfaction of all applicable securities laws then in effect. 

(d) Directors Awards. 

(i) Each Director of the Company will be eligible to receive discretionary grants of Awards under the Plan. If the Board or the compensation
committee of the Board separately has adopted or in the future adopts a compensation policy covering some or all Directors that provides for a predetermined formula grant that specifies the type of Award, the timing of the Date of Grant and the
number of shares to be awarded under the terms of the Plan, such formula grant will be incorporated by reference and will be administered as if such terms were provided under the terms of the Plan without any requirement that the Administrator
separately take action to determine the terms of such Awards. 
 (ii) Subject to the provisions of Section 11(a) relating to
adjustments upon changes in the shares of Common Stock, the aggregate dollar value of Awards (calculated as the Date of Grant fair value of such Awards for financial reporting purposes) granted under this Plan and cash compensation granted under
this Plan or otherwise paid by the Company during any calendar year to any one Non-Employee Director shall not exceed $300,000, rounded up to the nearest full Share. The foregoing limit shall not count any Tandem SARs (as defined in
Section 7(c)(i)). 
  

	6.	Option Provisions.  

 Each Option will be in such form and will contain
such terms and conditions as the Administrator deems appropriate. All Options will be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or
certificates will be issued for shares of Common Stock purchased on exercise of each type of Option. Notwithstanding the foregoing, the Company will have no liability to any Participant or any other person if an Option designated as an Incentive
Stock Option fails to qualify as such at any time. The provisions of separate Options need not be identical, but each Option will include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of
the following provisions: 
 (a) Term. Subject to the provisions of Section 5(b) regarding Ten Percent
Stockholders, no Option will be exercisable after the expiration of 10 years from the Date of Grant. 
 (b) Exercise Price.
The exercise price per share of Common Stock for each Option (the “Exercise Price”) will not be less than 100% of the Fair Market Value of such share on the Date of Grant; provided, however, that in the case of an
Incentive Stock Option granted to a Ten Percent Stockholder, the Exercise Price will be no less than 110% of the Fair Market Value per 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 13 

 
share of Common Stock on the Date of Grant. Notwithstanding the foregoing, an Option granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of
Section 424(a) of the Code, as if the Option was a statutory stock option, may be granted with an Exercise Price lower than the Fair Market Value per share on the Date of Grant. 

(c) Consideration. The Optionholder will pay the Exercise Price of Common Stock acquired pursuant to an Option, to the extent
permitted by applicable statutes and regulations, either (i) in cash or by certified or bank check at the time the Option is exercised or (ii) in the Administrator’s discretion, and upon such terms as the Administrator approves:
(1) by delivery to the Company of other Common Stock, duly endorsed for transfer to the Company, with a Fair Market Value on the date of delivery equal to the Exercise Price (or portion thereof) due for the number of shares being acquired, or
by means of attestation whereby the Participant identifies for delivery specific shares of Common Stock held by the Participant that have a Fair Market Value on the date of attestation equal to the Exercise Price (or portion thereof) and receives a
number of shares of Common Stock equal to the difference between the number of shares thereby purchased and the number of identified attestation shares of Common Stock (a “Stock for Stock Exchange”); (2) during any
period for which the Common Stock is readily tradable on an Established Securities Market, by a copy of instructions to a broker directing such broker to sell the Common Stock for which such Option is exercised, and to remit to the Company the
aggregate Exercise Price of such Options (a “Cashless Exercise”); (3) subject to the discretion of the Administrator, upon such terms as the Administrator shall approve, by notice of exercise including a statement
directing the Company to retain such number of shares of Common Stock from any transfer to the Optionholder (“Stock Withholding”) that otherwise would have been delivered by the Company upon exercise of the Option having a
Fair Market Value equal to all or part of the exercise price of such Option exercise, or (4) in any other form of legal consideration that may be acceptable to the Administrator, including without limitation with a full-recourse promissory
note; provided, however, if applicable law requires, the Optionholder shall pay the par value (if any) of Common Stock, if newly issued, in cash or cash equivalents. The interest rate payable under the terms of the promissory note may not be
less than the minimum rate (if any) necessary to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Administrator (in its sole discretion) shall specify the term, interest rate, amortization requirements (if
any) and other provisions of such note. Unless the Administrator determines otherwise, the holder shall pledge to the Company shares of Common Stock having a Fair Market Value at least equal to the principal amount of any such loan as security for
payment of the unpaid balance of the loan and such pledge must be evidenced by a pledge agreement, the terms of which the Administrator shall determine, in its discretion; provided, however, that each loan must comply with all
applicable laws, regulations and rules of the Board of Governors of the Federal Reserve System and any other governmental agency having jurisdiction. Unless the Administrator determines otherwise, the purchase price of Common Stock acquired pursuant
to an Option that is paid by delivery (or attestation) to the Company of other shares of Common Stock acquired, directly or indirectly from the Company, will be paid only by shares of Common Stock of the Company that have been held for more than six
months (or such other period of time as may be required to avoid a charge to earnings for financial accounting purposes). Notwithstanding the foregoing, during any period for which the Company has any class of its securities listed on a national
securities exchange in the United 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 14 

 
States, has securities registered under Section 12 of the Exchange Act, is required to file reports under Section 13(a) or 15(d) of the Exchange Act, or has a registration statement
pending under the Exchange Act, an exercise with a promissory note or other transaction by an Optionholder that involves or may involve a Prohibited Personal Loan is prohibited with respect to any Option under the Plan. Unless otherwise provided in
the terms of an Option Agreement, payment of the Exercise Price by a Participant who is an Insider in the form of a Stock for Stock Exchange is subject to pre-approval by the Administrator, in its sole discretion. The Administrator shall document
any such pre-approval in a manner that complies with the specificity requirements of Rule 16b-3, including the name of the Participant involved in the transaction, the nature of the transaction, the number of shares to be acquired or disposed of by
the Participant and the material terms of the Options involved in the transaction. 
 (d) Transferability of an Incentive Stock
Option. An Incentive Stock Option will not be transferable except by will or by the laws of descent and distribution and will be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the
Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, upon the death of the Optionholder, will thereafter be entitled to exercise the Option. 

(e) Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option may, in the sole discretion of the
Administrator, be transferable to a Permitted Transferee upon written approval by the Administrator to the extent provided in the Option Agreement. A Permitted Transferee includes: (i) a transfer by gift or domestic relations order to a member
of the Optionholder’s immediate family (child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law,
including adoptive relationships), any person sharing the Optionholder’s household (other than a tenant or employee), a trust in which these persons (or the Optionholder) have more than 50% of the beneficial interest, a foundation in which
these persons (or the Optionholder) control the management of assets, and any other entity in which these persons (or the Optionholder) own more than 50% of the voting interests; and (ii) such other transferees as may be permitted by the
Administrator in its sole discretion. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option will not be transferable except by will or by the laws of descent and distribution and will be
exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in
the event of the death of the Optionholder, will thereafter be entitled to exercise the Option. 
 (f) Vesting Generally. The
Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based
on performance or other criteria) as the Administrator may deem appropriate. The vesting provisions of individual Options may vary. The Administrator may, but will not be required to provide that no Option may be exercised for a fraction of a share
of Common Stock. The Administrator may, but will not be required to, provide for an acceleration of vesting and 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 15 

 
exercisability in the terms of any Option Agreement upon the occurrence of a specified event. Unless otherwise specified in the terms of any Option Agreement, each Option granted pursuant to the
terms of the Plan will become exercisable at a rate of 20% per year over the five year period commencing on the Date of Grant of the Option. 

(g) Termination of Continuous Service. Unless otherwise provided in an Option Agreement or in an employment or service agreement
the terms of which have been approved by the Administrator, if an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability or termination by the Company for Cause), the Optionholder may exercise
his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period ending on the earlier of (i) the date three months following the termination of the
Optionholder’s Continuous Service, or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option
Agreement, the Option will terminate. Unless otherwise provided in an Option Agreement or in an employment or service agreement the terms of which have been approved by the Administrator, or as otherwise provided in Sections 6(h),
(i) and (j) of this Plan, outstanding Options that are not exercisable at the time an Optionholder’s Continuous Service terminates for any reason other than for Cause (including an Optionholder’s death or Disability)
will be forfeited and expire at the close of business on the date of such termination. If the Optionholder’s Continuous Service terminates for Cause, all outstanding Options (whether or not vested) will be forfeited and expire as of the
beginning of business on the date of such termination for Cause. 
 (h) Extension of Termination Date. An Option Agreement may
also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service for any reason (other than upon the Optionholder’s death or Disability or termination by the Company for Cause) would
violate any applicable federal, state or local law, the Option will terminate on the earlier of (i) the expiration of the term of the Option in accordance with Section 6(a) or (ii) the date that is 30 days after the exercise of
the Option would no longer violate any applicable federal, state or local law. 
 (i) Disability of Optionholder. Unless
otherwise provided in an Option Agreement, or in an employment or service agreement the terms of which have been approved by the Administrator, if an Optionholder’s Continuous Service terminates as a result of the Optionholder’s
Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of time ending on the earlier of (i) the date 12
months following such termination or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option
will terminate. 
 (j) Death of Optionholder. Unless otherwise provided in an Option Agreement, or in an employment or service
agreement the terms of which have been approved by the Administrator, if an Optionholder’s Continuous Service terminates as a result of the 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 16 

 
Optionholder’s death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a
person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on the earlier of (i) the date 12 months
following the date of death or (ii) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option will terminate. 

(k) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value of Common Stock on the Date
of Grant with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds $100,000, the Options or portions thereof which exceed
such limit (according to the order in which they were granted) will be treated as Nonstatutory Stock Options. 
 (l) Early
Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common
Stock subject to the Option prior to the full vesting of the Option. In such case, the shares of Common Stock acquired on exercise shall be subject to the vesting schedule that otherwise would apply to determine the exercisability of the Option. Any
unvested shares of Common Stock so purchased may be subject to any other restriction the Administrator determines to be appropriate. 
 (m)
Transfer, Approved Leave of Absence. For purposes of Incentive Stock Options, no termination of employment by an Employee will be deemed to result from either (i) a transfer to the employment of the Company from an Affiliate or
from the Company to an Affiliate, or from one Affiliate to another; or (ii) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the period of such leave does not exceed three
months or, if longer, the Employee’s right to re-employment is guaranteed either by a statute or by contract. 
 (n)
Disqualifying Dispositions. Any Participant who makes a “disposition” (as defined in Section 424 of the Code) of all or any portion of shares of Common Stock acquired upon exercise of an Incentive Stock Option within two
years from the Date of Grant of such Incentive Stock Option or within one year after the issuance of the shares of Common Stock acquired upon exercise of such Incentive Stock Option will be required to immediately advise the Company in writing as to
the occurrence of the sale and the price realized upon the sale of such shares of Common Stock. 
  

	7.	Provisions of Awards Other Than Options. 

 (a) Restricted
Awards. A Restricted Award is an Award of actual shares of Common Stock (“Restricted Stock”) or hypothetical Common Stock units (“Restricted Stock Units”) having a value equal to the Fair
Market Value of an identical number of shares of Common Stock, which may, but need not, provide that such Restricted Award may not be sold, assigned, transferred or otherwise disposed of, pledged or hypothecated as collateral for a loan or 

 

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 17 

 
as security for the performance of any obligation or for any other purpose for such period (the “Restricted Period”) as the Administrator shall determine. Each Restricted
Award will be in such form and will contain such terms, conditions and Restricted Periods as the Administrator deems appropriate, including the treatment of dividends or dividend equivalents, as the case may be. The Administrator in its discretion
may provide for an acceleration of the end of the Restricted Period in the terms of any Restricted Award, at any time, including in the event a Change in Control occurs. The terms and conditions of the Restricted Award may change from time to time,
and the terms and conditions of separate Restricted Awards need not be identical, but each Restricted Award must include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following
provisions: 
 (i) Purchase Price. The purchase price of Restricted Awards, if any, will be determined by the Administrator, and may
be stated as cash, property, prior or future services. Shares of Common Stock acquired in connection with any Restricted Award may be issued for such consideration, having a value not less than the par value thereof, as determined from time to time
by the Administrator. 
 (ii) Consideration. The Participant shall pay the consideration for Common Stock acquired pursuant to the
Restricted Award either: (i) in cash at the time of purchase; or (ii) in any other form of legal consideration that may be acceptable to the Administrator in its discretion including, without limitation, a recourse promissory note,
property a Stock for Stock Exchange, or prior or future services that the Administrator determines have a value at least equal to the Fair Market Value of such Common Stock. Notwithstanding the foregoing, during any period for which the Company has
any class of its securities listed on a national securities exchange in the United States, has securities registered under Section 12 of the Exchange Act, is required to file reports under Section 13(a) or 15(d) of the Exchange Act, or has
a registration statement pending under the Securities Act, payment with a promissory note or other transaction by a Participant that involves or may involve a Prohibited Personal Loan is prohibited with respect to any Restricted Award under the
Plan. 
 (iii) Vesting. The Restricted Award and any shares of Common Stock acquired under the Restricted Award may, but need not, be
subject to a Restricted Period that specifies a Right of Repurchase in favor of the Company, or forfeiture in the event the consideration was in the form of services, in accordance with a vesting schedule to be determined by the Administrator. The
Administrator in its discretion may provide for an acceleration of vesting in the terms of any Restricted Award, at any time, including upon a Change in Control. The Administrator in its discretion may grant a Restricted Award that is, in whole or
in part, vested upon grant and not subject to a Restricted Period. 
 (iv) Termination of Participant’s Continuous Service.
Unless otherwise provided in a Restricted Award or in an employment or service agreement the terms of which have been approved by the Administrator, if a Participant’s Continuous Service terminates for any reason, the Company may exercise its
Right of Repurchase or otherwise reacquire, or the Participant shall forfeit the unvested portion of a Restricted Award acquired in consideration of services, and any or all of the shares of Common Stock held by the Participant that have not vested
as of the date of termination under the terms of the Restricted Award will be forfeited and the Participant will have no rights with respect to the Award. 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 18 

 (v) Transferability. Rights to acquire shares of Common Stock under the Restricted Award
will be transferable by the Participant only upon such terms and conditions as are set forth in the Award Agreement, as the Administrator shall determine in its discretion, so long as Common Stock awarded under the Restricted Award remains subject
to the terms of the Award Agreement. 
 (vi) Concurrent Tax Payment. The Administrator, in its sole discretion, may (but will not be
required to) provide for payment of a concurrent cash award in an amount equal, in whole or in part, to the estimated after tax amount required to satisfy applicable federal, state or local tax withholding obligations arising from the receipt and
deemed vesting of Restricted Stock for which an election under Code Section 83(b) may be required. 
 (vii) Lapse of
Restrictions. Upon the expiration or termination of the Restricted Period and the satisfaction of any other conditions prescribed by the Administrator (including, without limitation, the Participant’s satisfaction of applicable tax
withholding obligations attributable to the Award), the restrictions applicable to the Restricted Award will lapse and a stock certificate for the number of shares of Common Stock with respect to which the restrictions have lapsed will be delivered,
free of any restrictions except those that may be imposed by law, the terms of the Plan or the terms of a Restricted Award, to the Participant or the Participant’s beneficiary or estate, as the case may be, unless such Restricted Award is
subject to a deferral condition that complies with Code Section 409A and the regulations and interpretive authority issued thereunder as may be allowed or required by the Administrator in its sole discretion. The Company will not be required to
deliver any fractional share of Common Stock but will pay, in lieu thereof, the Fair Market Value of such fractional share in cash to the Participant or the Participant’s beneficiary or estate, as the case may be. With respect only to
Restricted Stock Units, unless otherwise subject to a deferral condition that complies with Code Section 409A requirements, the Common Stock certificate will be issued and delivered and the Participant will be entitled to the beneficial
ownership rights of such Common Stock not later than (1) the later of (x) the date that is 2 1⁄2 months after the end of the Participant’s
taxable year for which the Restricted Period ends and the Restricted Stock Unit is no longer subject to a substantial risk of forfeiture; or (y) the date that is 2 1⁄2 months after the end of the Company’s taxable year for which the Restricted Period ends and Restricted Stock Unit is no longer subject to a substantial risk of forfeiture; or (2) such earlier date as
may be necessary to avoid application of Code Section 409A to such Award. 
 (b) Performance Awards. 

(i) Nature of Performance Awards. A Performance Award is an Award entitling the recipient to vest in or acquire shares of Common Stock
or hypothetical Common Stock units having a value equal to the Fair Market Value of an identical number of shares of Common Stock that will be settled in the form of shares of Common Stock upon the attainment of specified performance goals. The
Administrator may make Performance Awards independent 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 19 

 
of or in connection with the granting of any other Award under the Plan. Performance Awards may be granted under the Plan to any Participant, including those who qualify for awards under other
performance plans of the Company. The Administrator in its sole discretion shall determine whether and to whom Performance Awards will be made, the performance goals applicable under each Award, the periods during which performance is to be
measured, and all other limitations and conditions applicable to the awarded shares; provided, however, that the Administrator may rely on the performance goals and other standards applicable to other performance plans of the Company
in setting the standards for Performance Awards under the Plan. 
 (ii) Performance Goals. 

(1) Performance goals will be based on a pre-established objective formula or standard that specifies the manner of determining the number of
shares of Common Stock under the Performance Award that will be granted or will vest if the performance goal is attained. The Administrator will determine the performance goals before the time that 25% of the service period has elapsed, but not
later than 90 days after the commencement of the service period to which the performance goal relates. 
 (2) Performance goals may be
based on one or more business criteria that apply to a Participant, a business unit or the Company and its Affiliates. Such business criteria include the following: revenue; sales; earnings before all or any of interest expense, taxes, depreciation
and/or amortization (“EBIT,” “EBITA,” or “EBITDA”); funds from operations; funds from operations per share; operating income; operating income per share; pre-tax or after-tax income; net cash provided by operating
activities; cash available for distribution; cash available for distribution per share; working capital and components thereof; sales (net or gross) measured by product line, territory, customer or customers, or other category; return on equity or
average stockholders’ equity, including total stockholder return on equity based on the net stock price change over a given period plus the dividends paid during that period; return on assets; return on capital; enterprise value or economic
value added; share price performance; improvements in the Company’s attainment of expense levels; implementation or completion of critical projects; improvement in cash-flow (before or after tax); net earnings; earnings per share; earnings from
continuing operations; net worth; credit rating; levels of expense, cost, or liability by category, operating unit, or any other delineation; or any increase or decrease of one or more of the foregoing over a specified period; or the occurrence of a
Change in Control. 
 (3) A performance goal may be measured over a performance period on a periodic, annual, cumulative or average basis
and may be established on a corporate-wide basis or established with respect to one or more operating units, divisions, subsidiaries, acquired businesses, minority investments, partnerships or joint ventures. More than one performance goal may be
incorporated in a performance objective, in which case achievement with respect to each performance goal may be assessed individually or in combination with each other. The Administrator may, in connection with the establishment of performance goals
for a performance period, establish a matrix setting forth the relationship between performance on two or more performance goals and the amount of the Performance Award payable for that performance 

 

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 20 

 
period. The level or levels of performance specified with respect to a performance goal may be established in absolute terms, as objectives relative to performance in prior periods, as an
objective compared to the performance of one or more comparable companies or an index covering multiple companies, or otherwise as the Administrator may determine. 

(4) Performance goals will be objective and, if the Company is required to be registered under Section 12 of the Exchange Act, will
otherwise meet the requirements of Section 162(m) of the Code. Performance goals may differ for Performance Awards granted to any one Participant or to different Participants. A Performance Award to a Participant who is a Covered Employee will
(unless the Administrator determines otherwise) provide that if the Participant’s Continuous Service ceases prior to the end of the performance period for any reason, such Award will be payable only (A) if the applicable performance
objectives are achieved and (B) to the extent, if any, determined by the Administrator. Such objective performance goals are not required to be based on increases in a specific business criterion, but may be based on maintaining the status quo
or limiting economic losses. With respect to Participants who are not Covered Employees, the Administrator may establish additional objective or subjective performance goals. 

(iii) Restrictions on Transfer. Performance Awards and all rights with respect to such Performance Awards may not be sold, assigned,
transferred, pledged or otherwise encumbered. 
 (iv) Satisfaction of Performance Goals. A Participant will be entitled to receive a
stock certificate evidencing the acquisition of shares of Common Stock under a Performance Award only upon satisfaction of all conditions specified in the written instrument evidencing the Performance Award (or in a performance plan adopted by the
Administrator), including, without limitation, the Participant’s satisfaction of applicable tax withholding obligations attributable to the Award. With respect only to a Performance Award that is denominated in hypothetical Common Stock units,
the Common Stock certificate will be issued and delivered and the Participant will be entitled to the beneficial ownership rights of such Common Stock (1) not later than (A) the date that is
2 1⁄2 months after the end of the Participant’s taxable year for which the Administrator certifies that the Performance Award conditions have been
satisfied and the Performance Award is no longer subject to a substantial risk of forfeiture; or (B) the date that is 2 1⁄2 months after the end of the
Company’s taxable year for which the Administrator certifies that the Performance Award conditions have been satisfied and the Performance Award is no longer subject to a substantial risk of forfeiture; or (2) such other date as may be
necessary to avoid application of Code Section 409A to such Award. 
 (v) Termination. Except as may otherwise be provided by
the Administrator at any time, a Participant’s rights in all Performance Awards will automatically terminate upon the Participant’s termination of employment (or business relationship) with the Company and its Affiliates for any reason.

 (vi) Acceleration, Waiver, Etc. Before the first date on which any class of the Company’s common equity securities is
required to be registered under Section 12 of the 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 21 

 
Exchange Act or after such date with respect to Participants who are not Covered Employees, at any time before the Participant’s termination of Continuous Service by the Company and its
Affiliates, the Administrator may in its sole discretion accelerate, waive or, subject to Section 12 hereof, amend any or all of the goals, restrictions or conditions imposed under any Performance Award. The Administrator in its
discretion may provide for an acceleration of vesting in the terms of any Performance Award at any time, including upon a Change in Control. Notwithstanding the foregoing, with respect to a Covered Employee, after the first date on which any class
of the Company’s common equity securities is required to be registered under Section 12 of the Exchange Act, no amendment or waiver of the performance goal will be permitted, and no acceleration of payment (other than in the form of Common
Stock) will be permitted unless the performance goal has been attained and the Award is discounted to reasonably reflect the time value of money attributable to such acceleration. 

(vii) Certification. Following the completion of each performance period, the Administrator shall certify in writing, in accordance
with the requirements of Section 162(m) of the Code, whether the performance objectives and other material terms of a Performance Award have been achieved or met. Unless the Administrator determines otherwise, Performance Awards will not be
settled until the Administrator has made the certification specified under this Section 7(b)(vii). 
 (c) Stock
Appreciation Rights. 
 (i) General. Stock Appreciation Rights may be granted either alone (“Free Standing
SARs”) or, provided the requirements of Section 7(c)(ii) are satisfied, in tandem with all or part of any Option granted under the Plan (“Tandem SARs”). In the case of a Nonstatutory Stock Option,
Tandem SARs may be granted either at or after the time of the grant of such Option. In the case of an Incentive Stock Option, Tandem SARs may be granted only at the time of the grant of the Incentive Stock Option. 

(ii) Grant Requirements. A Stock Appreciation Right may only be granted if it does not provide for the deferral of compensation within
the meaning of Code Section 409A. A Stock Appreciation Right does not provide for a deferral of compensation if: (1) the Strike Price may never be less than the Fair Market Value per share of the underlying Common Stock on the Date of
Grant, (2) the compensation payable under the Stock Appreciation Right can never be greater than the difference between the Strike Price and the Fair Market Value of the Common Stock on the date the Stock Appreciation Right is exercised,
(3) the number of shares of Common Stock subject to the Stock Appreciation Right is fixed on the Date of Grant of the Stock Appreciation Right, and (4) the Stock Appreciation Right does not include any feature for the deferral of
compensation other than the deferral of recognition of income until the exercise of the SAR. 
 (iii) Exercise and Payment. Upon
delivery to the Administrator of a written request to exercise a Stock Appreciation Right the holder of such SAR will be entitled to receive from the Company, an amount equal to the product of (1) the excess of the Fair Market Value, on the
date of such exercise, of one share of Common Stock over the Strike Price per share specified 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 22 

 
in such Stock Appreciation Right or its related Option; multiplied by (2) the number of shares for which such Stock Appreciation Right is exercised. Payment with respect to the exercise of a
Stock Appreciation Right will be paid on the date of exercise and made in shares of Common Stock valued at Fair Market Value on the date of exercise. Payment may be made in the form of shares of Common Stock (with or without restrictions as to
substantial risk of forfeiture and transferability, as determined by the Administrator in its sole discretion), cash or a combination thereof, as determined by the Administrator in its sole discretion. 

(iv) Strike Price. The Administrator will determine the Strike Price of a Free Standing SAR, which may not be less than 100% of the
Fair Market Value per share of Common Stock on the Date of Grant of such Stock Appreciation Right. The Strike Price of a Tandem SAR granted simultaneously with or subsequent to the grant of an Option and in conjunction therewith or in the
alternative thereto will be the Exercise Price of the related Option. A Tandem SAR will be transferable only upon the same terms and conditions as the related Option, and will be exercisable only to the same extent as the related Option;
provided, however, that a Tandem SAR, by its terms, will be exercisable only when the Fair Market Value per share of Common Stock subject to the Tandem SAR and related Option exceeds the Strike Price per share thereof. 

(v) Reduction in the Underlying Option Shares. Upon any exercise of a Stock Appreciation Right, the number of shares of Common Stock
for which any related Option will be exercisable will be reduced by the number of shares for which the Stock Appreciation Right will have been exercised. The number of shares of Common Stock for which a Stock Appreciation Right will be exercisable
will be reduced upon any exercise of any related Option by the number of shares of Common Stock for which such Option has been exercised. 

(vi) Written Request. Unless otherwise determined by the Administrator in its sole discretion, Stock Appreciation Rights will be
settled in the form of Common Stock. If permitted in the Award Agreement, a Participant may request that any exercise of a Stock Appreciation Right be settled for cash, but a Participant will not have any right to demand a cash settlement. A request
for cash settlement may be made only by a written request filed with the Corporate Secretary of the Company during the period beginning on the third business day following the date of release for publication by the Company of quarterly or annual
summary statements of earnings and ending on the twelfth business day following such date. Within 30 days of the receipt by the Company of a written request to receive cash in full or partial settlement of a Stock Appreciation Right or to exercise
such Stock Appreciation Right for cash, the Administrator shall, in its sole discretion, either consent to or disapprove, in whole or in part, such written request. A written request to receive cash in full or partial settlement of a Stock
Appreciation Right or to exercise a Stock Appreciation Right for cash may provide that, if the Administrator disapproves such written request, such written request will be deemed to be an exercise of such Stock Appreciation Right for shares of
Common Stock. 
 (vii) Disapproval by Administrator. If the Administrator disapproves in whole or in part any request by a
Participant to receive cash in full or partial settlement of a Stock Appreciation Right or to exercise such Stock Appreciation Right for cash, such disapproval will not affect such Participant’s right to exercise such Stock Appreciation Right
at a later date, to the 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 23 

 
extent that such Stock Appreciation Right will be otherwise exercisable, or to request a cash form of payment at a later date, provided that a request to receive cash upon such later exercise
will be subject to the approval of the Administrator. Additionally, such disapproval will not affect such Participant’s right to exercise any related Option. 

(viii) Restrictions on Transfer. Stock Appreciation Rights and all rights with respect to such Awards may not be sold, assigned,
transferred, pledged, or otherwise encumbered. 
  

	8.	Covenants of the Company.  

 (a) Availability of Shares.
During the terms of the Awards, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Awards. 

(b) Securities Law Compliance. Each Award Agreement will provide that no shares of Common Stock may be purchased or sold
thereunder unless and until any then applicable requirements of state, federal or applicable foreign laws and regulatory agencies have been fully complied with to the satisfaction of the Company and its counsel. The Company shall use reasonable
efforts to seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon exercise of the Awards; provided,
however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts, the Company is unable to
obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and
sell Common Stock upon exercise of such Awards unless and until such authority is obtained. 
  

	9.	Use of Proceeds from Stock.  

 Proceeds from the sale of Common Stock
pursuant to Awards will constitute general funds of the Company. 
  

	10.	Miscellaneous. 

 (a) Acceleration of Exercisability and
Vesting. The Administrator will have the power to accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the
Award stating the time at which it may first be exercised or the time during which it will vest. 
 (b) Stockholder Rights.
Except as provided in Section 11(a) hereof or as otherwise provided in an Award Agreement, no Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to
an Award unless and until the Participant has satisfied all requirements for exercise, payment or delivery of the Award, as applicable, pursuant to its terms and no adjustment will be made for dividends (ordinary or extraordinary, whether in cash,
securities or other property) or distributions of other rights for which the record date is prior to the date of issue of a Common Stock certificate. 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 24 

 (c) No Employment or Other Service Rights. Nothing in the Plan or any instrument
executed or Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an
Affiliate to terminate (i) the employment of an Employee with or without notice and with or without Cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or
(iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 

(d) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under
any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who
is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award; and (ii) to give written
assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The
foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (iii) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Award has been registered under a
then currently effective registration statement under the Securities Act or (iv) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then
applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws,
including, but not limited to, legends restricting the transfer of the Common Stock. 
 (e) Withholding Obligations. To the
extent provided by the terms of an Award Agreement and subject to the discretion of the Administrator, the Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under
an Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the
Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result of the exercise or acquisition of Common Stock under the Award, provided, however, that the Fair Market Value
of shares of Common Stock withheld does not exceed the minimum amount of tax required to be withheld by law; (iii) delivering to the Company previously owned and unencumbered shares of Common Stock; or (iv) by execution of a recourse
promissory note by a Participant. Notwithstanding the foregoing, during any period for which the Company has any class of its securities listed on a national securities exchange in 

 

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 25 

 
the United States, has securities registered under Section 12 of the Exchange Act, is required to file reports under Section 13(a) or 15(d) of the Exchange Act, or has a registration
statement pending under the Securities Act, payment of the tax withholding with a promissory note or other transaction by a Participant that involves or may involve a Prohibited Personal Loan is prohibited with respect to any Award. Unless otherwise
provided in the terms of an Option Agreement, payment of the tax withholding by a Participant who is an Insider by delivering previously owned and unencumbered shares of Common Stock or in the form of share withholding is subject to pre-approval by
the Administrator, in its sole discretion. The Administrator will document any such pre-approval in the case of a participant who is an Officer, Director or other Insider in a manner that complies with the specificity requirements of Rule 16b-3,
including the name of the Participant involved in the transaction, the nature of the transaction, the number of shares to be acquired or disposed of by the Participant and the material terms of the Award involved in the transaction. 

(f) Right of Repurchase. Each Award Agreement may provide that, following a termination of the Participant’s Continuous
Service, the Company may repurchase the Participant’s unvested Common Stock acquired under the Plan as provided in this Section 10(f) (the “Right of Repurchase”). The Right of Repurchase for unvested Common
Stock will be exercisable at a price equal to the lesser of the purchase price at which such Common Stock was acquired under the Plan or the Fair Market Value of such Common Stock (if an Award is granted solely in consideration of past services
without payment of any additional consideration, the unvested Common Stock will be forfeited without any repurchase). The Award Agreement may specify the period following a termination of the Participant’s Continuous Service during which the
Right of Repurchase may be exercised. 
  

	11.	Adjustments Upon Changes in Stock. 

 (a) Capitalization Adjustments.
If any change is made in the Common Stock subject to the Plan, or subject to any Award, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend
in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), then the Administrator shall
proportionately adjust (i) the aggregate number of shares of Common Stock or class of shares that may be purchased pursuant to Awards granted hereunder; (ii) the aggregate number of shares of Common Stock or class of shares that may be
purchased pursuant to Incentive Stock Options granted hereunder; (iii) the number and/or class of shares of Common Stock covered by outstanding Options and Awards; (iv) the maximum number of shares of Common Stock with respect to which
Options and Stock Appreciation Rights may be granted to any single holder during any calendar year; and (v) the Exercise Price of any Option and the Strike Price of any Stock Appreciation Right in effect prior to such change shall be
proportionately adjusted by the Administrator to reflect any increase or decrease in the number of issued shares of Common Stock or change in the Fair Market Value of such Common Stock resulting from such transaction; provided,
however, that any fractional shares resulting from the adjustment may be eliminated by a cash payment. The Administrator shall make such adjustments in a manner that will provide an appropriate 

 

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 26 

 
adjustment that neither increases nor decreases the value of such Award as in effect immediately prior to such corporate change, and its determination will be final, binding and conclusive. The
conversion of any securities of the Company that are by their terms convertible will not be treated as a transaction “without receipt of consideration” by the Company. 

(b) Dissolution or Liquidation. In the event of a dissolution or liquidation of the Company, then, subject to
Section 11(c), all outstanding Awards will terminate immediately prior to such event. 
 (c) Change in Control –
Asset Sale, Merger, Consolidation or Reverse Merger. In the event of a Change in Control, a dissolution or liquidation of the Company, an exchange of shares, or any corporate separation or division, including, but not limited to, a split-up,
a split-off or a spin-off, or a sale, in one or a series of related transactions, of all or substantially all of the assets of the Company; a merger or consolidation in which the Company is not the Surviving Entity; or a reverse merger in which the
Company is the Surviving Entity, but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then the Company, to the
extent permitted by applicable law, but otherwise in the sole discretion of the Administrator may provide for: (i) the continuation of outstanding Awards by the Company (if the Company is the Surviving Entity); (ii) the assumption of the
Plan and such outstanding Awards by the Surviving Entity or its parent; (iii) the substitution by the Surviving Entity or its parent of awards with substantially the same terms (including an award to acquire the same consideration paid to the
stockholders in the transaction described in this Section 11(c)) for such outstanding Awards and, if appropriate, subject to the equitable adjustment provisions of Section 11(a) hereof; (iv) the cancellation of such
outstanding Awards in consideration for a payment (in the form of stock or cash) equal in value to the Fair Market Value of vested Awards, or in the case of an Option, the difference between the Fair Market Value and the Exercise Price for all
shares of Common Stock subject to exercise (i.e., to the extent vested) under any outstanding Option; or (v) the cancellation of such outstanding Awards without payment of any consideration. If such Awards would be canceled without
consideration for vested Awards, the Participant will have the right, exercisable during the latter of the 10-day period ending on the fifth day prior to such merger or consolidation or 10 days after the Administrator provides the Award holder a
notice of cancellation, to exercise such Awards in whole or in part without regard to any installment exercise provisions in the Option Agreement. 
  

	12.	Amendment of the Plan and Awards. 

 (a) Amendment of Plan.
The Board at any time may amend or terminate the Plan. However, except as provided in Section 11(a) relating to adjustments upon changes in Common Stock, no amendment will be effective unless approved by the stockholders of the Company
to the extent stockholder approval is necessary to satisfy any applicable law or any securities exchange listing requirements. At the time of such amendment, the Board shall determine, upon advice from counsel, whether such amendment will be
contingent on stockholder approval. 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 27 

 (b) Stockholder Approval. The Board may, in its sole discretion, submit any other
amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to certain executive officers. 
 (c) Contemplated
Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the
Code and the regulations promulgated thereunder relating to Incentive Stock Options or to the nonqualified deferred compensation provisions of Section 409A of the Code and to bring the Plan and Awards granted hereunder into compliance
therewith. Notwithstanding the foregoing, neither the Board nor the Company nor any Affiliate will have any liability to any Participant or any other Person as to (a) any tax consequences expected, but not realized, by a Participant or any
other person due to the receipt, exercise, or settlement of any Award granted hereunder; or (b) the failure of any Award to comply with Section 409A of the Code. 

(d) Amendment of Awards; No Impairment of Rights.  

(i) The Administrator at any time may amend the terms of any one or more Awards. However, subject to Section 12(d)(ii), no
amendment may impair rights under any Award granted before such amendment. Except as otherwise permitted under Section 11, unless stockholder approval is obtained: (1) no amendment or modification may reduce the Exercise Price of
any Option or the Strike Price of any SAR; (2) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR, another Award or cash if such action will be considered a “repricing” for purposes of
the shareholder approval rules of the applicable securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted; and (3) the Committee may not take any other action that is considered a “repricing”
for purposes of the shareholder approval rules of the applicable securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted. 

(ii) No amendment of the Plan or an Award may impair rights under any Award granted before such amendment unless (1) the Company requests
the consent of the Participant and (2) the Participant consents in writing. For the avoidance of doubt, a cancellation of an Award where the Participant receives a payment equal in value to the Fair Market Value of the vested Award or, in the
case of vested Options or Stock Appreciation Rights, the difference between the Fair Market Value and the Exercise Price or Strike Price, is not an impairment of the Participant’s rights that requires consent of the Participant. 

 

	13.	General Provisions. 

 (a) Other Compensation Arrangements. Nothing
contained in the Plan will prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in
specific cases. 
  

Mammoth Energy Services, Inc. Equity Incentive Plan 

  
 28 

 (b) Recapitalizations. Each Award Agreement will contain provisions required to
reflect the provisions of Section 11(a). 
 (c) Delivery. Upon exercise of a right granted pursuant to an Award
under the Plan, the Company shall issue Common Stock or pay any amounts due within a reasonable period of time thereafter. Subject to any statutory or regulatory obligations the Company may otherwise have, for purposes of the Plan, 30 days will be
considered a reasonable period. 
 (d) Other Provisions. The Award Agreements authorized under the Plan may contain such other
provisions not inconsistent with the Plan, including, without limitation, restrictions upon the exercise of the Awards, as the Administrator may deem advisable. 

(e) Cancellation and Rescission of Awards for Detrimental Activity. 

(i) Upon exercise, payment or delivery pursuant to an Award, the Administrator may require a Participant to certify in a manner acceptable to
the Company that the Participant has not engaged in any Detrimental Activity. 
 (ii) Unless the Award Agreement specifies otherwise, the
Administrator may cancel, rescind, suspend, withhold or otherwise limit or restrict any unexpired, unpaid or deferred Awards at any time if the Participant engages in any Detrimental Activity. 

(iii) If a Participant engages in Detrimental Activity after any exercise, payment or delivery pursuant to an Award, during any period for
which any restrictive covenant prohibiting such activity is applicable to the Participant, such exercise, payment or delivery may be rescinded within one year after the Company knows or should have known of the occurrence of any Detrimental
Activity. In the event of any such rescission, the Participant shall pay to the Company the amount of any gain realized or payment received as a result of the exercise, payment or delivery, in such manner and on such terms and conditions as may be
required by the Company. The Company will be entitled to set-off against the amount of any such gain any amount owed to the Participant by the Company. 

(f) Clawback or Forfeiture. Notwithstanding any provision in this Plan or any Award Agreement to the contrary, if required by
Company policy, by the Dodd-Frank Wall Street Reform and Consumer Protection Act or the Sarbanes—Oxley Act of 2002 or by other applicable law, each Participant’s Award under this Plan shall be conditioned on repayment or forfeiture in
accordance with such applicable laws, Company policy, or any relevant provision of the related Award Agreement. By accepting an Award under this Plan, a Participant will have consented to any such clawback, repayment or forfeiture condition,
regardless of whether or not such condition is expressly stated in the Award Agreement. 
  

	14.	Market Stand-Off.  

 Each Option Agreement and Award Agreement will provide
that, in connection with any underwritten public offering by the Company of its equity securities, the Participant shall agree not to sell, make any short sale of, loan, hypothecate, pledge, grant any option for the repurchase

of, transfer the economic consequences of ownership or otherwise dispose or transfer for value or otherwise agree to engage in any of the foregoing transactions with respect to any Common Stock
without the prior written consent of the Company or its underwriters, for such period from and after the effective date of such registration statement as may be requested by the Company or such underwriters (the “Market
Stand-Off”). In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with respect to the shares of Common Stock acquired under the Plan until the end of the applicable stand-off period. If there is
any change in the number of outstanding shares of Common Stock by reason of a stock split, reverse stock split, stock dividend, recapitalization, combination, reclassification, dissolution or liquidation of the Company, any corporate separation or
division (including, but not limited to, a split-up, a split-off or a spin-off), a merger or consolidation; a reverse merger or similar transaction, then any new, substituted or additional securities that are by reason of such transaction
distributed with respect to any shares of Common Stock subject to the Market Stand-Off, or into which such shares of Common Stock thereby become convertible, will immediately be subject to the Market Stand-Off. 

 

	15.	Effective Date of Plan.  

 The Plan shall become effective as of the
Effective Date. No Award may be exercised (or in the case of a stock Award, may be granted) unless and until the Plan has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the Plan is
adopted by the Board. If the stockholders fail to approve the Plan within 12 months after the date on which the amendment and restatement of the Plan is adopted by the Board, any Awards that are contingent on stockholder approval shall be rescinded
and no additional Awards may be made under the Plan. 
  

	16.	Termination or Suspension of the Plan.  

 The Plan will terminate
automatically on the day before the 10th anniversary of the Effective Date (specified in Section 2(u)). No Award may be granted pursuant to the Plan after such date, but Awards theretofore granted may extend beyond that date. The Board may
suspend or terminate the Plan at any earlier date pursuant to Section 12(a) hereof. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 

 

	17.	Choice of Law. 

 The law of the State of Delaware will govern all questions
concerning the construction, validity and interpretation of the Plan, without regard to such state’s conflict of law rules. 
  

	18.	Limitation on Liability.  

 The Company and any Affiliate that is in
existence or that hereinafter comes into existence will have no liability to any Participant or any other person as to (a) the non-issuance or sale of shares of Common Stock as to which the Company has been unable to obtain from any regulatory
body having jurisdiction the authority deemed by counsel to the Company necessary to the lawful issuance and sale of any shares hereunder; (b) any tax consequences expected, but

not realized, by a Participant or any other person due to the receipt, exercise, or settlement of any Award granted hereunder; or (c) the failure of any Award that is determined to
constitute “nonqualified deferred compensation” to comply with Section 409A of the Code and the regulations thereunder. 
  

	19.	Execution.

has caused its authorized officer to execute the Plan as of the date specified below.
