a.Independent Agreement. The provisions of this Section 4 (collectively, the “Restrictive Covenants”) shall be construed as an agreement independent of any other provisions of this Employment Agreement or of any other agreement between the Employee and the Company, and the breach of any provision of this Employment Agreement or existence of any claim or cause of action of the Employee against the Company shall not constitute a defense to the enforcement by the Company of the Restrictive Covenants.

b.Confidentiality.

i.During the course of the Employee’s employment by the Company, the Employee will have access to certain trade secrets and confidential information relating to the Company and its affiliates (the “Protected Parties”) which is not readily available from sources outside the Company. The confidential and proprietary information and, in any material respect, trade secrets of the Protected Parties are among their most valuable assets, including, but not limited to, their customer, supplier and vendor lists, databases, competitive strategies, computer programs, frameworks, or models, their marketing programs, their sales, financial, marketing, training and technical information, and any other information, whether communicated orally, electronically, in writing or in other tangible forms concerning how the Protected Parties create, develop, acquire or maintain their products and marketing plans, target their potential customers and operate their drilling and hydraulic fracturing services and other businesses. The Protected Parties invested, and continue to invest, considerable amounts of time and money in their process, technology, know-how, obtaining and developing the goodwill of their customers, their other external relationships, their data systems and data bases, and all the information described above (hereinafter collectively referred to as “Confidential Information”), and any misappropriation or unauthorized disclosure of Confidential Information in any form would irreparably harm the Protected Parties. The Employee acknowledges that such Confidential Information constitutes valuable, highly confidential, special and unique property of the Protected Parties. The Employee shall hold in a fiduciary capacity for the benefit of the Protected Parties all Confidential Information relating to the Protected Parties and their businesses, which shall have been obtained by the Employee during the Employee’s employment by the Company and which shall not be or become public knowledge (other than by acts by the Employee or representatives of the

Employee in violation of this Employment Agreement). The Employee agrees he shall not, during the period the Employee is employed by the Company or at any time thereafter, disclose any Confidential Information, directly or indirectly, to any Person for any reason or purpose whatsoever, nor shall the Employee use it in any way, except (A) in the course of the Employee’s employment with, and for the benefit of, the Protected Parties, (B) to enforce any rights or defend any claims hereunder or under any other agreement to which the Employee is a party, provided that such disclosure is relevant to the enforcement of such rights or defense of such claims and is only disclosed in the formal proceedings related thereto, (C) when required to do so by a court of law, by any governmental agency having supervisory authority over the business of any of the NexTier Companies or by any administrative or legislative body (including a committee thereof) with jurisdiction to order him to divulge, disclose or make accessible such information; provided that the Employee shall give prompt written notice to the Company of such requirement, disclose no more information than is so required, and cooperate with any attempts by the Company to obtain a protective order or similar treatment, (D) as to such Confidential Information that becomes generally known to the public or trade without his violation of this Section 4(b)(i), or (E) to the Employee’s spouse, attorney and/or his personal tax and financial advisors as reasonably necessary or appropriate to advance the Employee’s tax, financial and other personal planning (each, an “Exempt Person”); provided, however, that any disclosure or use of Confidential Information by an Exempt Person shall be deemed to be a breach of this Section 4(b)(i) by the Employee. The Employee shall take all reasonable steps to safeguard the Confidential Information and to protect it against disclosure, misuse, espionage, loss and theft. The Employee understands and agrees that the Employee shall acquire no rights to any such Confidential Information.

ii.All files, records, documents, drawings, specifications, data, computer programs, evaluation mechanisms and analytics and similar items relating thereto or to the Business (as defined in Section 4(c)), as well as all customer lists, specific customer information, compilations of product research and marketing techniques of any of the NexTier Companies, whether prepared by the Employee or otherwise coming into the Employee’s possession, shall remain the exclusive property of the NexTier Companies and be returned to the Company at the time of separation of employment.

c.The Employee retains rights under the U.S. Defend Trade Secrets Act of 2016 (“DTSA”) which provides that an individual shall 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 (i)(A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or

other document filed in a lawsuit or other proceeding, if such filing is made under seal. In addition, DTSA provides that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (x) files any document containing the trade secret under seal and (y) does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended to limit any rights under DTSA.

d.Non-Competition. The Employee agrees that he/she will not, during his/her employment and during the Restricted Period in the Restricted Territory, directly or indirectly, (i) provide services that are the same or substantially similar to the services and/or duties the Employee performed for the Company for any individual, entity or company in a Competitive Business; (ii) perform duties in a position that would allow the Employee to use or disclose Company Confidential Information that the Employee obtained during employment with the Company for any company, individual or entity that is engaged in (or has committed plans to engaged in) a Competitive Business; or (iii) hold any direct or beneficial material economic interest in any entity that directly or indirectly engages in or proposes to engage in any Competitive Business. Notwithstanding the foregoing, nothing in this Agreement shall prevent Employee from (a) owning, for passive investment purposes not intended to circumvent this Agreement, one percent or less of the publicly traded common equity securities of any company engaged in a Competitive Business or (b) if Employee is a licensed attorney, engaging in the practice of law to the extent such services do not violate Employee’s other obligations hereunder or Employee’s professional responsibilities to the Company.

A “Competitive Business” is defined as well completion services and products that the Company was engaged in during Employee’s employment or had initiated substantial plans to engage in during Employee’s employment (including, but not limited to, horizontal and vertical fracturing, wireline perforation and logging and engineered solutions and cementing).

The Employee acknowledges that in the event of breach of the restrictions in this Section or if the Company is required to file a lawsuit to enforce this Agreement, the Restricted Period in this Section will be extended for the period of time from the date of termination of employment to (i) the date of the filing of the lawsuit or (ii) the date of the last violation of the obligations under this Agreement, whichever is latest, regardless of whether the covenants are reformed

n.Remedies; Specific Performance. The Parties acknowledge and agree that the Employee’s breach or threatened breach of any of the restrictions set forth in Section 4 will result in irreparable and continuing damage to the Protected Parties for which there may be no adequate remedy at law and that the Protected Parties shall be entitled to seek equitable relief, including specific performance and

injunctive relief as remedies for any such breach or threatened or attempted breach, without requiring the posting of a bond. The Employee hereby consents to the grant of an injunction (temporary or otherwise) against the Employee or the entry of any other court order against the Employee prohibiting and enjoining him from violating, or directing him to comply with any provision of this Section 4. The Employee also agrees that such remedies shall be in addition to any and all remedies, including damages, available to the Protected Parties against him for such breaches or threatened or attempted breaches.

If the courts of any one or more of such jurisdictions hold the Restrictive Covenants wholly invalid or unenforceable by reason of the breadth of such scope or otherwise, it is the intention of the parties that such determination not bar or in any way affect the Company’s right to the relief provided above in the courts of any other jurisdiction within the geographical scope of such Restrictive Covenants, as to breaches of such Restrictive Covenants in such other respective jurisdictions, such Restrictive Covenants as they relate to each jurisdiction being, for this purpose, severable into diverse and independent covenants.

6.No Tax Representations; Section 409A.

a.Neither the Company nor its representatives and attorneys have made, nor do they make, any promise or warranty whatsoever with regard to the tax consequences, if any, of any issuance, grant, lapse of restriction, forfeiture or other event made to or on behalf of or affecting the Employee in connection with this Employment Agreement. The Employee agrees that if he deems it necessary he has or will retain a professional tax advisor to inform the Employee regarding the tax consequences to the Employee, if any, of this Employment Agreement. The parties agree and affirm that each shall bear sole responsibility for their respective tax consequences that may arise from or relate to any payment described in this Employment Agreement. The Employee acknowledges that if applicable law requires the Company to make any report or disclosure to any taxing authority with respect to any payment made or consideration provided to or on behalf of the Employee in connection with this Employment Agreement, the Company may do so.

b.Notwithstanding the foregoing, the intent of the parties is that payments and benefits under this Employment Agreement that constitute non-qualified deferred compensation within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall comply with Code Section 409A, and, accordingly, to the maximum extent permitted, this Employment Agreement shall be interpreted and administered to be in compliance with Code Section 409A. Any term used in this Employment Agreement which is defined in Code Section 409A or the regulations promulgated thereunder (the “Regulations”) shall have the meaning set forth therein unless otherwise specifically defined herein. Any obligations under this Employment Agreement that arise in connection with the Employee’s “termination of employment,” “termination” or other similar references shall only be triggered if the termination of employment or termination qualifies as a “separation from service” within the meaning of §1.409A-1(h) of the Regulations.

c.Notwithstanding any other provision of this Employment Agreement, if, at the time of the termination of the Employee’s employment, the Employee is a “specified employee,” as defined in Section 409A or the Regulations, and any payments upon such termination under this Employment Agreement will result in additional tax or interest to the Employee under Code Section 409A, he will not be entitled to receive such payments until the date which is the earlier of (i) six months and one day after such separation from service and (ii) the date of the

Employee’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 6(c) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) will be paid or provided to the Employee in a lump sum and any remaining payments and benefits due under this Employment Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

d.If any expense reimbursement or in-kind benefit provided to the Employee under this Employment Agreement is determined to be “deferred compensation” within the meaning of Section 409A, then such reimbursement or in-kind benefit shall be made or provided in accordance with the requirements of Code Section 409A, including that (i) in no event shall any fees, expenses or other amounts eligible to be reimbursed by the Company under this Employment Agreement be paid later than December 31 of the year following the year during which the applicable fees, expenses or other amounts were incurred, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits that the Company is obligated to pay or provide, in any given calendar year shall not affect the expenses that the Company is obligated to reimburse, or the in-kind benefits that the Company is obligated to pay or provide, in any other calendar year, provided that the foregoing clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect; (iii) the Employee’s right to have the Company pay or provide such reimbursements and in-kind benefits may not be liquidated or exchanged for any other benefit; and (iv) in no event shall the Company’s obligations to make such reimbursements or to provide such in-kind benefits apply later than the Employee’s remaining lifetime (or, if longer, through the tenth anniversary of the Effective Date).

e.For purposes of Code Section 409A, the Employee’s right to receive any installment payments shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Employment Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company. In no event may the Employee, directly or indirectly, designate the calendar year of any payment to be made under this Employment Agreement, to the extent such payment is subject to Code Section 409A.
