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.

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.
