have the authority, in its sole and absolute discretion, to:

Agreement; and 
 (x)    make any other determination and take any other action that the Committee deems necessary or
desirable for the administration of the Plan. 

 The express grant of any specific power to the Committee, and the taking of any action by the
Committee, shall not be construed as limiting any power or authority of the Committee. Any action of the Committee shall be final, conclusive and binding on all persons, including the Company, its Affiliates, stockholders, Participants,
beneficiaries, and permitted transferees under Section 7(a) or other persons claiming rights from or through a Participant. 

(b)    Delegation of Authority. The Committee may delegate any or all of its powers and duties under the Plan to a
subcommittee of directors or to any officer of the Company, including the power to perform administrative functions and grant Awards; provided, however, that such delegation does not violate applicable law. Upon any such delegation,
all references in the Plan to the “Committee,” other than in Section 8, shall be deemed to include any subcommittee or officer of the Company to whom such powers have been delegated by the Committee. Any such
delegation shall not limit the right of such subcommittee members or such an officer to receive Awards; provided, however, that such subcommittee members and any such officer may not grant Awards to himself or herself, a member of the
Board, or any executive officer (as defined under Rule 3b-7 promulgated under the Exchange Act) of the Company or an Affiliate, or take any action with respect to any Award previously granted to himself or
herself, a member of the Board, or any such executive officer of the Company or an Affiliate. The Committee may also appoint agents who are not executive officers of the Company or members of the Board to assist in in administering the Plan,
provided that such individuals may not be delegated the authority to grant or modify any Awards that will, or may, be settled in Stock. 

(c)    Limitation of Liability. The Committee and each member thereof shall be entitled to, in good faith, rely or
act upon any report or other information furnished to him or her by any officer or employee of the Company or any of its Affiliates, the Company’s legal counsel, independent auditors, consultants or any other agents assisting in the
administration of the Plan. Members of the Committee and any officer or employee of the Company or any of its Affiliates acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or
made in good faith with respect to the Plan, and shall, to the fullest extent permitted by law, be indemnified and held harmless by the Company with respect to any such action or determination. 

4.    Stock Subject to Plan. 

(a)    Number of Shares Available for Delivery. Subject to adjustment in a manner consistent with Section 8,
shares of Stock are reserved and available for delivery with respect to Awards. 
 (b)    Application of Limitation
to Grants of Awards. Subject to Section 4(c), no Award may be granted if the number of shares of Stock that may be delivered in connection with such Award exceeds the number of shares of Stock remaining available under
the Plan minus the number of shares of Stock issuable in settlement of or relating to then-outstanding Awards. The Committee may adopt reasonable counting procedures to ensure appropriate counting, avoid double counting and make adjustments if the
number of shares of Stock actually delivered differs from the number of shares previously counted in connection with an Award. 

 (c)    Availability of Shares Not Delivered under Awards. Shares of
Stock subject to an Award under the Plan that expires or is cancelled, forfeited, exchanged, settled in cash or otherwise terminated (including (i) shares forfeited with respect to Restricted Stock, and (ii) the number of shares withheld
or surrendered to the Company in payment of any taxes relating to Awards) shall be considered “delivered shares” under the Plan, shall not be available for delivery with respect to Awards, and shall continue to be considered issuable or
related to outstanding Awards for purposes of Section 4(b). 
 5.    Eligibility.
Awards may be granted under the Plan only to Eligible Persons. 
 6.    Specific Terms of
Awards. 
 (a)    General. Awards may be granted on the terms and conditions set forth in this
Section 6. Awards granted under the Plan may, in the discretion of the Committee, be granted either alone, in addition to, or in tandem with any other Award. In addition, the Committee may impose on any Award, at the date
of grant or thereafter (subject to Section 10), such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine. 

(b)    Restricted Stock. The Committee is authorized to grant Restricted Stock to Eligible Persons on the following
terms and conditions: 
 (i)    Restrictions. Restricted Stock shall be subject to such restrictions on
transferability, risk of forfeiture and other restrictions, if any, as the Committee may impose. Except as provided in Section 7(a)(ii) and Section 7(a)(iii), during the restricted period applicable to the Restricted Stock, the
Restricted Stock may not be sold, transferred, pledged, hedged, hypothecated, margined or otherwise encumbered by the Participant. 

(ii)    Dividends and Splits. As a condition to the grant of an Award of Restricted Stock, the Committee may allow
a Participant to elect, or may require, that any cash dividends paid on a share of Restricted Stock be automatically reinvested in additional shares of Restricted Stock, applied to the purchase of additional Awards or deferred without interest to
the date of vesting of the associated Award of Restricted Stock. Unless otherwise determined by the Committee and specified in the applicable Award Agreement, Stock distributed in connection with a Stock split or Stock dividend, and other property
(other than cash) distributed as a dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Stock with respect to which such Stock or other property has been distributed. 

(iii)    Vesting. The Restricted Stock shall be subject to the vesting schedule as set forth in the applicable
Award Agreement, and such vesting schedule shall be the same as the remaining portion of the vesting schedule applicable to the unvested Class B Units in Liberty Oilfield Services Holdings. 

 7.    Certain Provisions Applicable to
Awards. 
 (a)    Limit on Transfer of Awards. 

(i)    Except as provided in Sections 7(a)(ii) and (iii), no Award, and no right under any such Award, may
be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the
Company or any Affiliate. 
 (ii)    To the extent specifically provided by the Committee, an Award may be transferred
by a Participant without consideration to immediate family members or related family trusts, limited partnerships or similar entities or on such terms and conditions as the Committee may from time to time establish. 

(iii)    An Award may be transferred pursuant to a domestic relations order entered or approved by a court of competent
jurisdiction upon delivery to the Company of a written request for such transfer and a certified copy of such order. 

(b)    Evidencing Stock. The Stock or other securities of the Company delivered pursuant to an Award may be
evidenced in any manner deemed appropriate by the Committee in its sole discretion, including in the form of a certificate issued in the name of the Participant or by book entry, electronic or otherwise, and shall be subject to such stop transfer
orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Stock or other securities are then listed, and any applicable federal,
state or other laws, and the Committee may cause a legend or legends to be inscribed on any such certificates to make appropriate reference to such restrictions. Further, if certificates representing Restricted Stock are registered in the name of
the Participant, the Company may retain physical possession of the certificates and may require that the Participant deliver a stock power to the Company, endorsed in blank, related to the Restricted Stock. 

(c)    Consideration for Grants. Awards may be granted for such consideration, including services, as the Committee
shall determine, but shall not be granted for less than the minimum lawful consideration. 
 8.    Subdivision
or Consolidation; Recapitalization; Change in Control; Reorganization. 

(a)    Existence of Plans and Awards. The existence of the Plan and the Awards granted hereunder shall not affect
in any way the right or power of the Company, the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or
consolidation of the Company, any issue of debt or equity securities ahead of or affecting Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets
or business or any other corporate act or proceeding. 
 (b)    Additional Issuances. Except as expressly
provided herein, the issuance by the Company of shares of stock of any class, including upon conversion of shares or obligations of the Company convertible into such shares or other securities, and in any case

 
whether or not for fair value, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to Awards theretofore granted or the
purchase price per share of Stock, if applicable. 
 (c)    Subdivision or Consolidation of Shares. The terms of
an Award and the share limitations under the Plan shall be subject to adjustment by the Committee from time to time, in accordance with the following provisions: 

(i)    If at any time, or from time to time, the Company shall subdivide as a whole (by reclassification, by a Stock
split, by the issuance of a distribution on Stock payable in Stock, or otherwise) the number of shares of Stock then outstanding into a greater number of shares of Stock or in the event the Company distributes an extraordinary cash dividend, then,
as appropriate (A) the maximum number of shares of Stock available for delivery with respect to Awards shall be increased proportionately, and the kind of shares or other securities available for the Plan shall be appropriately adjusted and
(B) the number of shares of Stock (or other kind of shares or securities) that may be acquired under any then outstanding Award shall be increased proportionately. 

(ii)    If at any time, or from time to time, the Company shall consolidate as a whole (by reclassification, by reverse
Stock split, or otherwise) the number of shares of Stock then outstanding into a lesser number of shares of Stock, then, as appropriate (A) the maximum number of shares of Stock available for delivery with respect to Awards shall be decreased
proportionately, and the kind of shares or other securities available for the Plan shall be appropriately adjusted and (B) the number of shares of Stock (or other kind of shares or securities) that may be acquired under any then outstanding
Award shall be decreased proportionately. 
 (d)    Recapitalization. In the event of any change in the capital
structure or business of the Company or other corporate transaction or event that would be considered an “equity restructuring” within the meaning of ASC Topic 718 and, in each case, that would result in an additional compensation expense
to the Company pursuant to the provisions of ASC Topic 718, if adjustments to Awards with respect to such event were discretionary or otherwise not required (each such an event, an “Adjustment Event”), then the
Committee shall equitably adjust (i) the aggregate number or kind of shares that thereafter may be delivered under the Plan, (ii) the number or kind of shares or other property (including cash) subject to an Award, and (iii) the terms
and conditions of Awards to equitably reflect such Adjustment Event (“Equitable Adjustments”). In the event of any change in the capital structure or business of the Company or other corporate transaction or
event that would not be considered an Adjustment Event, and is not otherwise addressed in this Section 8, the Committee shall have complete discretion to make Equitable Adjustments (if any) in such manner as it deems
appropriate with respect to such other event. 
 (e)    Change in Control and Other Events. Except to the extent
otherwise provided in any applicable Award Agreement, vesting of any Award shall not occur solely upon the occurrence of a Change in Control and, in the event of a Change in Control or other changes in the Company or the outstanding Stock by reason
of a recapitalization, reorganization, merger, consolidation, combination, exchange or other relevant change occurring after the date of the 

 
grant of any Award, the Committee, acting in its sole discretion without the consent or approval of any holder, may exercise any power enumerated in Section 3 (including
the power to accelerate vesting, waive any forfeiture conditions or otherwise modify or adjust any other condition or limitation regarding an Award) and may also effect one or more of the following alternatives, which may vary among individual
holders and which may vary among Awards held by any individual holder: 
 (i)    redeem in whole or in part outstanding
Awards by requiring the mandatory surrender to the Company by selected holders of some or all of the outstanding Awards held by such holders (irrespective of whether such Awards are then vested or exercisable) as of a date, specified by the
Committee, in which event the Committee shall thereupon cancel such Awards and pay to each holder an amount of cash or other consideration per Award (other than a Dividend Equivalent or Cash Award, which the Committee may separately require to be
surrendered in exchange for cash or other consideration determined by the Committee in its discretion) equal to the Change in Control Price; 

(ii)    cancel Awards that remain subject to a restricted period as of the date of a Change in Control or other such
event without payment of any consideration to the Participant for such Awards; or 
 (iii)    make such adjustments to
Awards then outstanding as the Committee deems appropriate to reflect such Change in Control or other such event (including the substitution, assumption, or continuation of Awards by the successor company or a parent or subsidiary thereof); 

provided, however, that so long as the event is not an Adjustment Event, the Committee may determine in its sole discretion that no adjustment
is necessary to Awards then outstanding. If an Adjustment Event occurs, this Section 8(e) shall only apply to the extent it is not in conflict with Section 8(d). 

9.    General Provisions. 

(a)    Tax Withholding. The Company and any of its Affiliates are authorized to withhold from any Award granted, or
any payment relating to an Award, including from a distribution of Stock, taxes due or potentially payable in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the
Company, its Affiliates and Participants to satisfy the payment of withholding taxes and other tax obligations relating to any Award in such amounts as may be determined by the Committee. The Committee shall determine, in its sole discretion, the
form of payment acceptable for such tax withholding obligations, including the delivery of cash or cash equivalents, Stock (including previously owned shares, net settlement, a broker-assisted sale, or other cashless withholding or surrender of the
amount of shares issued pursuant to the Award), other property, or any other legal consideration the Committee deems appropriate. Any determination made by the Committee to allow a Participant who is subject to Rule
16b-3 to pay taxes with shares of Stock through net settlement or previously owned shares shall be approved by either a committee made up of solely two or more Qualified Members or the full Board. If such tax
withholding amounts are satisfied through net settlement or previously owned shares, 

 
the maximum number of shares of Stock that may be so withheld or surrendered shall be the number of shares of Stock that have an aggregate Fair Market Value on the date of withholding or
surrender equal to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for federal, state, foreign and/or local tax purposes, including payroll taxes, that may be utilized without creating adverse
accounting treatment for the Company with respect to such Award, as determined by the Committee. 
 (b)    Limitation
on Rights Conferred under Plan. Neither the Plan nor any action taken hereunder shall be construed as (i) giving any Eligible Person or Participant the right to continue as an Eligible Person or Participant or in the employ or service of
the Company or any of its Affiliates, (ii) interfering in any way with the right of the Company or any of its Affiliates to terminate any Eligible Person’s or Participant’s employment or service relationship at any time,
(iii) giving an Eligible Person or Participant any claim to be granted any Award under the Plan or to be treated uniformly with other Participants and/or employees and/or other service providers, or (iv) conferring on a Participant any of
the rights of a stockholder of the Company unless and until the Participant is duly issued or transferred shares of Stock in accordance with the terms of an Award. 

(c)    Governing Law; Submission to Jurisdiction. All questions arising with respect to the provisions of the Plan
and Awards shall be determined by application of the laws of the State of Delaware, without giving effect to any conflict of law provisions thereof, except to the extent Delaware law is preempted by federal law. The obligation of the Company to sell
and deliver Stock hereunder is subject to applicable federal and state laws and to the approval of any governmental authority required in connection with the authorization, issuance, sale, or delivery of such Stock. With respect to any claim or dispute related to or arising under the Plan, the Company and each Participant who accepts an Award hereby consent to the exclusive jurisdiction, forum and venue of the
state and federal courts located in the State of Delaware. 
 (d)    Severability and Reformation. If any
provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such
provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision
shall be stricken as to such jurisdiction, person or Award and the remainder of the Plan and any such Award shall remain in full force and effect. 

(e)    Unfunded Status of Awards; No Trust or Fund Created. The Plan is intended to constitute an
“unfunded” plan for certain incentive awards. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or
any other person. To the extent that any person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or such
Affiliate. 

 (f)    Nonexclusivity of the Plan. Neither the adoption of the Plan by
the Board nor its submission to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or a committee thereof to adopt such other incentive arrangements as it may deem desirable,
including incentive arrangements and awards which do not constitute “performance-based compensation” under Section 162(m). Nothing contained in the Plan shall be construed to prevent the Company or any of its Affiliates from taking any
corporate action which is deemed by the Company or such Affiliate to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan. No employee, beneficiary or other
person shall have any claim against the Company or any of its Affiliates as a result of any such action. 

(g)    Fractional Shares. No fractional shares of Stock shall be issued or delivered pursuant to the Plan or any
Award, and the Committee shall determine in its sole discretion whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional shares of Stock or whether such fractional shares of Stock or any rights thereto
shall be cancelled, terminated, or otherwise eliminated with or without consideration. 
 (h)    Interpretation.
Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision
thereof. Words in the masculine gender shall include the feminine gender, and, where appropriate, the plural shall include the singular and the singular shall include the plural. In the event of any conflict between the terms and conditions of an
Award Agreement and the Plan, the provisions of the Plan shall control. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific
items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words
of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. References herein to any
agreement, instrument or other document means such agreement, instrument or other document as amended, supplemented and modified from time to time to the extent permitted by the provisions thereof and not prohibited by the Plan. 

(i)    Facility of Payment. Any amounts payable hereunder to any individual under legal disability or who, in the
judgment of the Committee, is unable to manage properly his financial affairs, may be paid to the legal representative of such individual, or may be applied for the benefit of such individual in any manner that the Committee may select, and the
Company shall be relieved of any further liability for payment of such amounts. 
 (j)    Conditions to Delivery of
Stock. Nothing herein or in any Award Agreement shall require the Company to issue any shares with respect to any Award if that issuance would, in the opinion of counsel for the Company, constitute a violation of the Securities Act, any other
applicable statute or regulation, or the rules of any applicable securities exchange or securities association, as then in effect. In addition, each Participant who receives an Award under the Plan shall not sell or otherwise dispose of Stock that
is acquired upon grant or vesting of an Award in any manner that would constitute a violation of any applicable federal or state securities laws, the Plan or the rules, regulations or other requirements of the SEC or any stock exchange upon which
the Stock is then listed. At the time of any grant of any Award, the 

 
Company may, as a condition precedent to the settlement of any Award, require from the Participant (or in the event of his or her death, his or her legal representatives, heirs, legatees, or
distributees) such written representations, if any, concerning the holder’s intentions with regard to the retention or disposition of the shares of Stock being acquired pursuant to the Award and such written covenants and agreements, if any, as
to the manner of disposal of such shares as, in the opinion of counsel to the Company, may be necessary to ensure that any disposition by that holder (or in the event of the holder’s death, his or her legal representatives, heirs, legatees, or
distributees) will not involve a violation of the Securities Act, any other applicable state or federal statute or regulation, or any rule of any applicable securities exchange or securities association, as then in effect. Stock or other securities
shall not be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including any tax withholding) is received by the Company. 

(k)    Clawback. The Plan and all Awards granted hereunder are subject to any written clawback policies that the
Company, with the approval of the Board or an authorized committee thereof, may adopt either prior to or following the Effective Date, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010
and rules promulgated thereunder by the SEC and that the Company determines should apply to Awards. Any such policy may subject a Participant’s Awards and amounts paid or realized with respect to Awards to reduction, cancelation, forfeiture or
recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Company’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such
clawback policy. 
 (l)    Status under ERISA. The Plan shall not constitute an “employee benefit plan”
for purposes of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended. 
 (m)    Plan
Effective Date and Term. The Plan was adopted by the Board to be effective on the Effective Date. No Awards may be granted under the Plan on and after the tenth anniversary of the Effective Date, which is
                    , 2017. However, any Award granted prior to such termination (or any earlier termination pursuant to
Section 10), and the authority of the Board or Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award in accordance with the terms of the
Plan, shall extend beyond such termination until the final disposition of such Award. 
 10.    Amendments to the
Plan and Awards. The Committee may amend, alter, suspend, discontinue or terminate any Award or Award Agreement, the Plan or the Committee’s authority to grant Awards without the consent of stockholders or Participants, except that any
amendment or alteration to the Plan, including any increase in any share limitation, shall be subject to the approval of the Company’s stockholders not later than the annual meeting next following such Committee action if such stockholder
approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system on which the Stock may then be listed or quoted, and the Committee may otherwise, in its discretion, determine to submit
other changes to the Plan to stockholders for approval; provided, that, without the consent of an affected Participant, no such Committee action may materially and adversely affect the rights of such Participant under any previously granted
and outstanding 

 
Award. For purposes of clarity, any adjustments made to Awards pursuant to Section 8 will be deemed not to materially and adversely affect the rights of any Participant
under any previously granted and outstanding Award and therefore may be made without the consent of affected Participants.EX-10.8

RESTRICTED STOCK GRANT NOTICE 

 EXHIBIT A 

FORM OF RESTRICTED STOCK AGREEMENT 

This Restricted Stock Agreement (this “Agreement”) is made as of the Date of Grant set forth in the Grant Notice
to which this Agreement is attached by and between Liberty Oilfield Services Inc., a Delaware corporation (the “Company”), and (“Employee”). 

1.    Award. The Company hereby grants to Employee the number of shares of Restricted Stock set forth
in the Grant Notice (the “Restricted Shares”) on the terms and conditions set forth in the Grant Notice, this Agreement and the Plan, which is incorporated herein by reference as a part of this Agreement. In the
event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. 

2.    Forfeiture Restrictions.

(a)    The Restricted Shares may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred,
encumbered or disposed of except as provided in this Agreement or the Plan. 
 (b)    In the event of the termination of
Employee’s employment with the Company, except as otherwise provided in the Grant Notice, Employee shall immediately and without any further action by the Company, forfeit and surrender to the Company for no consideration all of the Restricted
Shares with respect to which the Forfeiture Restrictions have not lapsed in accordance with Section 2(e) as of the date of such termination. 

(c)    The prohibition against transfer and the obligation to forfeit and surrender the Restricted Shares to the Company
upon a termination of employment as provided in this Section 2 are referred to herein as the “Forfeiture Restrictions.” The Forfeiture Restrictions shall be binding upon and enforceable against any
transferee of the Restricted Shares. 
 (d)    The Restricted Shares shall be released from the Forfeiture Restrictions
in accordance with the vesting schedule set forth in the Grant Notice. The Restricted Shares with respect to which the Forfeiture Restrictions lapse without forfeiture are referred to herein as the “Earned
Shares.” As soon as administratively practicable following the release of any Stock from the Forfeiture Restrictions, the Company shall, as applicable, either deliver to Employee the certificate or certificates representing such
Stock in the Company’s possession belonging to Employee, or, if the Stock is held in book-entry form, then the Company shall remove the notations indicating that the Stock is subject to the restrictions of this Agreement. Employee (or the
beneficiary or personal representative of Employee in the event of Employee’s death or disability, as the case may be) shall deliver to the Company any representations or other documents or assurances as the Company or its representatives deem
necessary or advisable in connection with any such delivery. 
 3.    Dividends
and Other Distributions. Dividends and other distributions that are paid or distributed with respect to Restricted Shares (whether in the form of shares of Stock or other property
(including cash)) (referring to herein as “Retained Distributions”) shall be subject 

  
 EXHIBIT A

 
to the transfer restrictions and risk of forfeiture applicable to the related Restricted Share and shall be held by the Company or other depository as may be designated by the Committee as a
depository for safekeeping. If the Restricted Share to which such Retained Distributions relate is forfeited to the Company, then such Retained Distributions shall be forfeited to the Company at the same time such Restricted Share is so
forfeited. If the Restricted Share to which such Retained Distributions relate becomes vested, then such Retained Distributions shall be paid and distributed to Employee within 60 days after such Restricted Share becomes vested. Distributions
paid or distributed in the form of securities with respect to Restricted Shares shall bear such legends, if any, as may be determined by the Committee from time to time to reflect the terms and conditions of this Agreement and to comply with
applicable securities laws. 
 4.    Rights as
Stockholder. Except as otherwise provided herein, upon issuance of the Restricted Shares by the Company, Employee shall have all the rights of a stockholder of the Company with respect to such Restricted Shares subject to the
restrictions herein, including the right to vote the Restricted Shares. 
 5.    Confidentiality,
Non-Competition and Non-Solicitation. By accepting the award of Restricted Shares hereunder, Employee
expressly intends and agrees to be legally bound by the covenants set forth in Exhibit C. Employee expressly acknowledges and affirms that the grant of Restricted Shares hereunder further aligns Employee’s interests with the
Company’s long-term business interests, and Employee acknowledges that the Restricted Shares would not be granted to Employee hereunder if Employee had not agreed to be bound by the covenants set forth in Exhibit C. For the avoidance of
doubt, notwithstanding any provision in this Agreement or the Plan to the contrary, in the event of any breach of any of the covenants set forth in Exhibit C or the provisions of any other confidentiality,
non-competition or non-solicitation covenant in any other agreement by and between the Company or any of its Affiliates and Employee, if, as of the date of such breach
(the “Breach Date”), the Forfeiture Restrictions have not lapsed with respect to some or all of the Restricted Shares, Employee shall, for no consideration, immediately forfeit and surrender to the Company
all of such Restricted Shares. For the avoidance of doubt, the remedies set forth in this Section 5 shall not be deemed the exclusive remedies for a breach of any of the covenants set forth in Exhibit C, but shall be in addition to all
remedies available at law or in equity, including, without limitation, injunctive relief, and the recovery of damages from Employee and Employee’s agents. 

6.    Refusal to Transfer; Stop-Transfer
Notices. The Company shall not be required (a) to transfer on its books any shares of Stock that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (b) to treat as
owner of such shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such shares shall have been so transferred. Employee agrees that, in order to ensure compliance with the restrictions referred to
herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

7.    Restricted Shares Not
Transferable. The Restricted Shares may not be sold, pledged, assigned or transferred in any manner unless and until the Forfeiture Restrictions have lapsed. No Restricted Shares or any interest or right therein or part
thereof shall be liable for the debts, contracts or engagements of Employee or his or her successors in interest or shall be 

  
 A-2 

 
subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect. 

8.    Employment Relationship. For purposes of this Agreement, Employee shall be
considered to be employed by the Company as long as Employee remains an employee of the Company or any of its subsidiaries or an employee of a corporation or other entity (or a parent or subsidiary of such corporation or other entity) assuming or
substituting a new restricted stock award for the Restricted Shares. Any question as to whether and when there has been a termination of such employment, and the cause of such termination, shall be determined by the Committee or its delegate, and
such determination shall be final, conclusive and binding for all purposes. 
 9.    Agreement
to Furnish Information. Employee agrees to furnish to the Company all information requested by the Company to enable it to comply with any reporting or other requirement imposed upon the
Company by or under any applicable statute or regulation. 
 10.    Entire
Agreement; Amendment. This Agreement constitutes the entire agreement of the parties with regard to the subject matter hereof, and contains all the covenants, promises, representations, warranties and
agreements between the parties with respect to the Restricted Shares granted hereby. Without limiting the scope of the preceding sentence, all prior understandings and agreements, if any, among the parties hereto relating to the subject matter
hereof are hereby null and void and of no further force and effect. Notwithstanding the foregoing, the parties expressly acknowledge and agree that this Agreement does not supersede or replace, but instead complements and is in addition to, all
agreements and obligations that Employee has to the Company and each member of the Company Group (whether contained in a prior written agreement or otherwise) with regard to: (i) confidentiality and the
non-use, non-disclosure, return and protection of trade secrets, confidential and proprietary information and materials;
(ii) non-competition and non-solicitation; and (iii) the ownership of intellectual property rights (in each case, including, without limitation, those
covenants set forth in the Restricted Unit Agreement(s) entered into between Employee and Liberty Oilfield Services Holdings). 

11.    Successors and Assigns. The Company may assign any of its
rights under this Agreement without Employee’s consent. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein and in the Plan, this
Agreement will be binding upon Employee and Employee’s beneficiaries, executors, administrators and the person(s) to whom the Restricted Shares may be transferred by will or the laws of descent or distribution. 

12.    Defined Terms. In addition to the terms defined in the body of this Agreement,
the following capitalized words shall have the meanings indicated below. Capitalized terms used but not specifically defined herein shall have the meanings specified in the Plan or the Grant Notice.

more of the events or occurrences described in clauses (A) through (F) below occurs, (ii) the Company notifies Employee in reasonable detail as to such occurrence (including, in such notice, the Company’s intent to terminate his

SECTION 83(b) ELECTION PACKAGE 

  
 EXHIBIT B

 EXHIBIT C 

FORM OF COVENANTS RELATED TO CONFIDENTIALITY AND NONCOMPETITION 

Employee acknowledges and recognizes the highly competitive nature of the business of the Company and its subsidiaries (the Company and such
subsidiaries being referred to collectively herein as the “Company Group”), the amount of sensitive, proprietary and confidential information and trade secrets necessarily involved in the discharge of
Employee’s position with the Company Group, and the harm to the Company Group that would result if such knowledge or expertise was disclosed or made available to a competitor. Employee further acknowledges and agrees that Employee’s
receipt of the grant of Restricted Shares that Employee has received further aligns Employee’s interests with the Company’s long-term business interests. Based on that understanding and in recognition of the fact that Employee will
receive, and have access to, Confidential Information (as defined below) and that the Company Group has a legitimate business interest in protecting its Confidential Information and goodwill, Employee hereby expressly agrees as follows: 

1.    Confidentiality and Protection of
Information. 
 (a)    Obligation to Maintain Confidentiality. 

(i)    Employee acknowledges that the continued success of the Company Group depends upon the use and protection of
Confidential Information, and that Employee will have access to such information in a manner that requires restrictions on Employee’s use and disclosure for purposes unrelated to business of the Company. Therefore, Employee agrees that Employee
shall not disclose or use for Employee’s own account any Confidential Information, except as reasonably necessary for the performance of Employee’s duties on behalf of any member of the Company Group, without prior written consent of an
executive officer (or the Board if Employee is an executive officer at the relevant time), unless and to the extent that any Confidential Information is required to be disclosed pursuant to any applicable law, regulatory action or court order. Upon
the termination of Employee’s employment with the Company, and at any other time upon the request of any member of the Company Group, Employee shall deliver to the Company Group, all memoranda, notes, plans, records, reports and other documents
(and copies thereof) relating to the business of the Company Group (including, without limitation, all documents, files (including without limitation electronically stored information) and other materials constituting or reflecting Confidential
Information) that Employee may then possess or have under Employee’s control. 
 (ii)    As used herein,
“Confidential Information” means any non-public, confidential or proprietary information belonging to, or which is currently held by or is hereafter acquired, developed or
used by, the Company or any other member of the Company Group, including all such information relating to business opportunities or other geological, geophysical, engineering, operational, economic, financial, management or other aspects of any
member of the Company Group’s business, operations, properties or prospects, whether oral or in written form. In no event will the definition of “Confidential Information” include information that is, or becomes, generally known to
and available for use by the public other than as a result of Employee’s improper acts or failure to act. 

  
 EXHIBIT C

 (b)    Ownership of Intellectual Property. If Employee creates,
invents, designs, develops, contributes to or improves (or has created, invented, designed, developed, contributed to or improved) any works of authorship, inventions, materials, documents or other work product or other intellectual property, either
alone or in conjunction with third parties, at any time during Employee’s employment with the Company Group (collectively, “Works”), to the extent that such Works were created, invented, designed, developed, contributed
to, or improved with the use of any Company Group resources and/or within the scope of such employment (collectively, the “Company Works”), Employee shall promptly and fully disclose such Company Works to the
Company Group. Any copyrightable work falling within the definition of Company Works shall be deemed a “work made for hire” as such term is defined in 17 U.S.C. § 101. Employee hereby (i) irrevocably assigns, transfers and
conveys, to the fullest extent permitted by applicable law, all right, title and interest in and to the Company Works on a worldwide basis (including, without limitation, rights under patent, copyright, trademark, trade secret, unfair competition
and related laws) to the Company Group or such other entity as the Company Group shall designate, to the extent ownership of any such rights does not automatically vest in the Company Group under applicable law and (ii) waives any moral rights
therein to the fullest extent permitted under applicable law. Employee agrees that Employee will not use any Company Works for Employee’s personal benefit, the benefit of a competitor of any member of the Company Group, or for the benefit of
any Person or entity other than the Company Group. Employee agrees to execute any further documents and take any further reasonable actions requested by the Company Group to assist it in validating, effectuating, maintaining, protecting, enforcing,
perfecting, recording, patenting or registering any of its rights hereunder, all at the Company Group’s sole expense. Upon termination of Employee’s employment, Employee shall deliver to the Company Group all originals and all duplicates
and copies of all documents, records, notebooks, and similar repositories of or containing Confidential Information then in Employee’s possession, whether prepared by Employee or not; and at any time thereafter, if any such materials are
brought to Employee’s attention or Employee discovers them in Employee’s possession, Employee shall deliver such materials to the Company Group immediately upon such notice or discovery. 

(c)    Third Party Information. Employee understands that members of the Company Group will receive from third
parties confidential or proprietary information (“Third Party Information”) subject to a duty on behalf of member(s) of the Company Group to maintain the confidentiality of such information and to
use it only for certain purposes. During Employee’s employment with the Company Group and at all times thereafter, and without in any way limiting any provision of this Agreement, Employee will hold information which Employee knows, or
reasonably should know, to be Third Party Information in the strictest confidence and will not disclose to anyone (other than personnel of the Company Group who need to know such information in connection with their work for the Company Group) or
use, except in connection with Employee’s work for the Company Group, Third Party Information unless expressly authorized in writing by the Board or the information (i) becomes generally known to and available for use by the public other
than as a result of Employee’s improper acts or omissions or (ii) is required to be disclosed pursuant to any applicable law, regulatory action or court order. 

  
 C-2 

 (d)    Permitted Disclosures. 

(i)    Employee understands that nothing in this Exhibit B shall be construed to prohibit Employee from reporting
possible violations of law or regulation to any governmental agency or regulatory body or making other disclosures that are protected under any law or regulation, or from filing a charge with or participating in any investigation or proceeding
conducted by any governmental agency or regulatory body. 
 (ii)    Employee understands that the Defend Trade Secrets
Act provides that Employee may not be held criminally or civilly liable under any Federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a Federal, state, or local government official, either directly or
indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In the
event that Employee files a lawsuit for retaliation by any member of the Company Group for reporting a suspected violation of law, Employee may disclose the trade secret to Employee’s attorney and use the trade secret information in the court
proceeding, if Employee files any document containing the trade secret under seal and do not disclose the trade secret, except pursuant to court order. 

2.    Restricted Activities. During the term of Employee’s employment with the Company and for the 12-month period following termination of such employment (the “Restricted Period”), regardless of the reason for such termination and regardless of whether termination is by the
Company or Employee, Employee agrees that he shall not, and shall cause his Affiliates [, spouse, children (including those by adoption) and Affiliates of his spouse and children] not to: 

(a)    directly or indirectly, participate with (as an employee, consultant, partner, investor, lender, advisor, officer
or director), consult, advise, sponsor or promote or invest in any Competing Business; provided, notwithstanding the foregoing, Employee’s ownership (together with his Affiliates [, children, spouse and Affiliates of his children and spouse])
of up to 1% of any class of equity or other securities of any entity listed on a national securities exchange or quotation system or in the over-the-counter market shall
not violate this clause (a) so long as neither such Employee nor any of his Affiliates [, children, spouse or Affiliates or his children or spouse] provides any services of any nature to such entity; or 

(b)    hire, solicit or attempt to solicit or partner with, directly or indirectly, any consultant, independent contractor
or employee of the Company or any subsidiary (or person that was an employee, consultant or independent contractor of the Company or any subsidiary within 12 months prior to such Employee’s employment termination) if, in the case of a
consultant or independent contractor (but not employee), such person’s relationship with the Company or any subsidiary would be interfered with. 

3.    Equitable Relief. Employee acknowledges that in the event of a breach of any of
the provisions of this Exhibit C, the Company Group (or its successors) would sustain irreparable harm and damages that would be extremely difficult if not impossible to calculate, and, therefore, Employee agrees that in addition to any other
remedies that the Company Group may 

  
 C-3 

 
have under this Exhibit C or otherwise at law or in equity, the Company Group shall be entitled to obtain equitable relief, including specific performance and injunctions restraining
Employee from committing or continuing any such violation of this Exhibit C, without any requirement that the Company Group post a bond. Such relief shall be in addition to all other relief available to each member of the Company Group, at
law and equity. The Restricted Period applicable to a particular provision of this Exhibit C shall be extended for the period equal to the time period that Employee is in breach of such provision. 

4.    Reasonableness of Restraints. It is agreed by the parties
that the foregoing covenants impose a reasonable restraint on Employee and are no greater than necessary to protect the Company Group’s legitimate business interests, including the protection of the Company Group’s trade secrets,
Confidential Information and goodwill. In the event any court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth herein are unreasonable, then it is the intention of the parties that such
restrictions be enforced to the fullest extent that the court deems reasonable, and the covenants contained herein shall thereby be reformed. 

5.    Miscellaneous. 

(a)    Severability. If any term, provision, covenant or condition of this Exhibit C (or any part
thereof) is held by a court of competent jurisdiction to be illegal, invalid, unenforceable or void, the validity and enforceability of the remainder of this Exhibit C (and parts thereof) shall not in any way be affected, impaired or
invalidated. 
 (b)    Survival. Employee’s obligations under this Exhibit C shall survive the
date that Employee is no longer employed or engaged by any member of the Company Group, regardless of the reason that such relationship ends.

(c)    Restricted Stock Agreement and Plan. This Exhibit C shall be subject to the provisions of
Sections 8, 10 and 11 of the Restricted Stock Agreement and Sections 9(c) and 9(h) of the Plan, which provisions are hereby incorporated by reference as a part of this Exhibit C.  

(d)    Third Party Beneficiaries. Each member of the Company Group that is not a signatory hereto shall be a
third party beneficiary of Employee’s representations, commitments, covenants, and obligations under this Exhibit C and shall have the right to enforce this Exhibit C as if a party hereto. 

  
 C-4 

 EXHIBIT D 

FORM OF CLASS B UNIT SURRENDER AGREEMENT 

This Class B Unit Surrender Agreement (this “Surrender Agreement”) is made as of the date set forth
on the signature page hereto (the “Effective Date”) by the unitholder listed on the signature page hereto (the “Unitholder”), with respect to all of the unvested Class B Units (as
defined below) (“Units”) held by the Unitholder. 
 1.    Surrender
and Cancellation of Unvested Class B Units. The Unitholder hereby surrenders and relinquishes to the
Company for cancellation all of the Unitholder’s right, title and interest in and to the              Class B Units in Liberty Oilfield Services Holdings (the
