TERM AND TERMINATION OF EMPLOYMENT 

3.1 Term. Unless sooner terminated pursuant to other provisions hereof, the Company agrees to employ Executive for the
period beginning on the Effective Date and ending on the third anniversary of the Effective Date (the “Initial Expiration Date”); provided, however, that beginning on the Initial Expiration Date, and on each anniversary of
the Initial Expiration Date thereafter, if Executive’s employment under this Agreement has not been terminated pursuant to Sections 3.2 or 3.3, then said term of employment shall automatically be extended for additional one-year periods (each a “Renewal Term”) unless, on or before the date that is 60 days prior to the first day of any such Renewal Term, either party gives written notice to the other party
that no such automatic extension shall occur, in which case the term of employment shall terminate as of the Initial Expiration Date or the end of the current Renewal Term, as applicable. 

3.2 Company’s Right to Terminate. Notwithstanding the provisions of Section 3.1, Executive’s
employment with the Company shall automatically terminate upon Executive’s death and the Company may terminate Executive’s employment under this Agreement at any time for any of the following reasons by providing Executive with a Notice of

 3 

 
of employment by Executive pursuant to this Section 3.3, the Date of Termination specified in the Notice of Termination shall not be less than 15 nor more than 60 days from the date such
Notice of Termination is given, and the Company may require a Date of Termination earlier than that specified in the Notice of Termination (and, if such earlier Date of Termination is so required, then it shall not change the basis for the
termination of Executive’s employment nor be construed or interpreted as a termination of employment pursuant to Section 3.1 or Section 3.2). 

3.4 Deemed Resignations. Unless otherwise agreed to in writing by Nine Energy or the Company and Executive prior to the
termination of Executive’s employment, any termination of Executive’s employment shall constitute (a) an automatic resignation of Executive as an officer of the Company and each affiliate of the Company and (b) an automatic
resignation of Executive from the Board (if applicable), from the board of directors or similar governing body of any affiliate of the Company and from the board of directors or similar governing body of any corporation, limited liability entity or
other entity in which the Company or any affiliate holds an equity interest and with respect to which board or similar governing body Executive serves as the Company’s or such affiliate’s designee or other representative. 

3.5 Meaning of Termination of Employment. For all purposes of this Agreement, Executive shall be considered to have
terminated employment with the Company when Executive incurs a “separation from service” with the Company within the meaning of section 409A(a)(2)(A)(i) of the Code and the applicable Treasury regulations and interpretive guidance issued
thereunder. 
 ARTICLE IV

amount of each Annual Bonus shall be determined in the discretion of the Board. The Company shall pay each Annual Bonus, if any, as soon as reasonably practicable after its receipt of audited financial statements for the applicable calendar year to
which the bonus relates (the “Bonus Year”), but in no event shall such Annual Bonus, if any, be paid later than March 31 of the calendar year that follows such Bonus Year; provided, however, that Executive will be
entitled to receive payment of an Annual Bonus for a Bonus Year only if Executive is employed by the Company on December 31 of the Bonus Year to which the Annual Bonus relates.

subject to the terms and conditions of the applicable benefit plans and programs in effect from time to time, Executive shall be eligible to participate in all benefit plans and programs of the Company, including improvements or modifications of the

receipt of supporting documentation reasonably satisfactory to the Company (but in any event not later than the close of Executive’s taxable year following the taxable year in which the expense is incurred by Executive); provided, however,
that, upon Executive’s termination of employment with the Company, in no event shall any additional reimbursement be made prior to the Section 409A Payment Date to the extent such payment delay is required under section 409A(a)(2)(B)(i) of the
Code. In no event shall any reimbursement be made to Executive for such fees and expenses after the later of (a) the first anniversary of the date of Executive’s death or (b) the date that is five years after the date of
Executive’s termination of employment with the Company (other than by reason of Executive’s death).

ARTICLE V 
 PROTECTION
OF INFORMATION 
 5.1 Disclosure to and Property of the Company. For purposes of this Article V, the term
“the Company” shall include the Company and any of its affiliates, and any reference to “employment” or similar terms shall include a director, consulting and/or secondment relationship. All information, trade secrets, designs,
ideas, concepts, improvements, product developments, discoveries and inventions, whether patentable or not, that are conceived, made, developed, disclosed to or acquired by Executive, individually or in conjunction with others, during the period of
Executive’s employment by the Company (whether during business hours or otherwise and whether on the Company’s premises or otherwise and whether prior to the 

  
 5 

 
Effective Date or after) that relate to the Company’s or any of its affiliates’ businesses, trade secrets, products or services (including, without limitation, all such information
relating to corporate opportunities, strategies, business plans, product specifications, compositions, manufacturing and distribution methods and processes, research, financial and sales data, pricing terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the identity of key contacts within the customer’s organizations or within the organization of acquisition prospects, or production, marketing and merchandising techniques,
prospective names and marks) and all writings or materials of any type embodying any of such information, ideas, concepts, improvements, discoveries, inventions and other similar forms of expression (collectively, “Confidential
Information”) shall be disclosed to the Company and are and shall be the sole and exclusive property of the Company. Moreover, all documents, videotapes, written presentations, brochures, drawings, memoranda, notes, records, files,
correspondence, manuals, models, specifications, computer programs, E-mail, voice mail, electronic databases, maps, drawings, architectural renditions, models and all other writings or materials of any type
embodying any of such Confidential Information or the Company’s ideas, concepts, improvements, discoveries, inventions and other similar forms of expression (collectively, “Work Product”) are and shall be the sole and
exclusive property of the Company. Executive agrees to perform all actions reasonably requested by the Company to establish and confirm such exclusive ownership. Upon termination of Executive’s employment with the Company, for any reason,
Executive promptly shall deliver all Confidential Information and Work Product, and all copies thereof, to the Company. 
 5.2
Disclosure to Executive. The Company shall disclose to Executive and place Executive in a position to have access to or develop Confidential Information and Work Product of the Company; and shall entrust Executive with business
opportunities of the Company; and shall place Executive in a position to develop business goodwill on behalf of the Company. 
 5.3
No Unauthorized Use or Disclosure. Executive agrees to preserve and protect the confidentiality of all Confidential Information and Work Product. Executive agrees that Executive will not, at any time during or after
Executive’s employment with the Company, make any unauthorized disclosure of, and Executive shall not remove from the Company premises, Confidential Information or Work Product of the Company, or make any use thereof, except, in each case, in
the carrying out of Executive’s responsibilities hereunder. Executive shall use all reasonable efforts to cause all persons or entities to whom any Confidential Information shall be disclosed by Executive hereunder to preserve and protect the
confidentiality of such Confidential Information. Executive shall have no obligation hereunder to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by law; provided, however, that in the
event disclosure is required by applicable law, Executive shall provide the Company with prompt notice of such requirement prior to making any such disclosure, so that the Company may seek an appropriate protective order. At the request of the
Company at any time, Executive agrees to deliver to the Company all Confidential Information that Executive may possess or control. Executive agrees that all Confidential Information and Work Product (whether now or hereafter existing) conceived,
discovered or made by Executive during the period of Executive’s employment by the Company exclusively belongs to the Company (and not to Executive), and upon request by the Company for specified Confidential Information and/or Work Product,
Executive will promptly disclose such Confidential Information and/or Work Product to the Company and perform all actions reasonably requested by the Company to 

  
 6 

 
establish and confirm such exclusive ownership. Affiliates of the Company shall be third party beneficiaries of Executive’s obligations under this Article V. As a result of Executive’s
employment by the Company, Executive may also from time to time have access to, or knowledge of, confidential information or work product of third parties, such as customers, suppliers, partners, joint venturers, and the like, of the Company and its
affiliates. Executive also agrees to preserve and protect the confidentiality of such third party confidential information and work product. 

5.4 Ownership by the Company. If, during Executive’s employment by the Company, Executive creates any work of
authorship fixed in any tangible medium of expression that is the subject matter of copyright (such as videotapes, written presentations, or acquisitions, computer programs, E-mail, voice mail, electronic
databases, drawings, maps, architectural renditions, models, manuals, brochures, or the like) relating to the Company’s business, products, or services, whether such work is created solely by Executive or jointly with others (whether during
business hours or otherwise and whether on the Company’s premises or otherwise), including any Work Product, the Company shall be deemed the author of such work if the work is prepared by Executive in the scope of Executive’s employment;
or, if the work relating to the Company’s business, products, or services is not prepared by Executive within the scope of Executive’s employment but is specially ordered by the Company as a contribution to a collective work, as a part of
a motion picture or other audiovisual work, as a translation, as a supplementary work, as a compilation, or as an instructional text, then the work shall be considered to be work made for hire and the Company shall be the author of the work. If the
work relating to the Company’s business, products, or services is neither prepared by Executive within the scope of Executive’s employment nor a work specially ordered that is deemed to be a work made for hire during Executive’s
employment by the Company, then Executive hereby agrees to assign, and by these presents does assign, to the Company all of Executive’s worldwide right, title, and interest in and to such work and all rights of copyright therein. 

5.5 Assistance by Executive. During the period of Executive’s employment by the Company, Executive shall assist the
Company and its nominee, at any time, in the protection of the Company’s or its affiliates’ worldwide right, title and interest in and to Confidential Information and Work Product and the execution of all formal assignment documents
requested by the Company or its nominee(s) and the execution of all lawful oaths and applications for patents and registration of copyright in the United States and foreign countries. After Executive’s employment with the Company terminates, at
the request from time to time and expense of the Company, Executive shall assist the Company or its nominee(s) in the protection of the Company’s or its affiliates’ worldwide right, title and interest in and to Confidential Information and
Work Product and the execution of all formal assignment documents requested by the Company or its nominee and the execution of all lawful oaths and applications for patents and registration of copyright in the United States and foreign countries
provided, however, that such assistance from Executive after Executive’s employment with the Company terminates shall not require Executive to expend unreasonable periods of time or unreasonably interfere with any obligations Executive may have
to provide services to other persons or entities. 

  
 7 

 5.6 Remedies. Executive acknowledges that money damages would not be a
sufficient remedy for any breach of this Article V by Executive, and the Company shall be entitled to enforce the provisions of this Article V by terminating payments then owing to Executive under this Agreement or otherwise and to specific
performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Article V but shall be in addition to all remedies available at law or in equity,
including the recovery of damages from Executive and Executive’s agents. However, if it is determined that Executive has not committed a breach of this Article V, then the Company shall resume the payments and benefits due under this Agreement
and pay to Executive and Executive’s spouse, if applicable, all payments and benefits that had been suspended pending such determination. 

ARTICLE VI 
 EFFECT OF
TERMINATION OF EMPLOYMENT ON COMPENSATION 
 6.1 Effect of Termination of Employment on Compensation. 

(a) If Executive’s employment hereunder shall terminate at the expiration of the term provided in Section 3.1 after
either party has given the other party written notice of non-renewal, for any reason described in Section 3.2(a) or 3.2(b), pursuant to Executive’s resignation for other than Good Reason or by reason
of Executive’s death, then all compensation and all benefits to Executive hereunder shall terminate contemporaneously with such termination of employment, except that Executive shall be entitled to (i) payment of all accrued and unpaid
Base Salary earned to the Date of Termination as well as any Annual Bonus that has been earned pursuant to Section 4.2 for the calendar year ending on or prior to the Date of Termination but remains unpaid as of the Date of Termination (which
Annual Bonus, if any, shall be paid in a lump sum at the time provided for payment in Section 4.2), (ii) reimbursement for all incurred but unreimbursed expenses for which Executive is entitled to reimbursement in accordance with
Section 4.4, and (iii) benefits to which Executive is entitled under the terms of any applicable benefit plan or program. 

(b) If Executive’s employment hereunder shall terminate pursuant to Executive’s resignation for Good Reason or by
action of the Company pursuant to Section 3.2 for any reason other than those encompassed by Section 3.2(a) or 3.2(b), then all compensation and all benefits to Executive hereunder shall terminate contemporaneously with such termination of
employment, except that (i) Executive shall be entitled to receive the compensation and benefits described in clauses (i) through (iii) of Section 6.1(a), and (ii) if, on the Date of Termination, the Company does not have a
right to terminate Executive’s employment under Section 3.2(a) or 3.2(b), then subject to (x) Executive’s execution and delivery to the Company by the Release Expiration Date (and
non-revocation within any time provided to do so) of a release of all claims in a form acceptable to the Company (the “Release”), which shall release and discharge the Company and its
affiliates, subsidiaries and benefit plans, and their respective stockholders, officers, directors, managers, members, partners, employees, fiduciaries, agents, representatives and other affiliated persons and entities from any and all claims and
causes of action of any kind or character, including all claims and causes of action arising out of Executive’s employment with the Company or its affiliates; and (y) Executive’s continued compliance with Executive’s obligations
under Articles V and VII, then Executive shall be entitled to receive the following payments and benefits: 

  
 8 

 (A) A severance payment equal to the aggregate of: (i) Executive’s
then-current annualized Base Salary and (ii) Executive’s then-current target Annual Bonus (the aggregate sum of (i) and (ii) being the “Severance Amount”), which Severance Amount will be divided into 12
substantially equal installments. On the last day of the month that includes the date that is 60 days after the Date of Termination, the Company shall pay to Executive, without interest, a number of such installments equal to the number of such
installments that would have been paid during the period beginning on the Date of Termination and ending on such last day of the month had the installments been paid on a monthly basis commencing on the Company’s monthly payroll date coincident
with or next following the Date of Termination, and each of the remaining installments shall be paid on a monthly basis thereafter; provided, however, that to the extent, if any, that the aggregate amount of such installments that would otherwise be
paid pursuant to the preceding provisions of this clause (A) after March 15 of the calendar year following the calendar year in which the Date of Termination occurs (the “Applicable
March 15”) exceeds the maximum exemption amount under Treasury Regulation section 1.409A-1(b)(9)(iii)(A), then such excess shall be paid on the Applicable
March 15 (or the first business day preceding the Applicable March 15 if the Applicable March 15 is not a business day) and such installments payable after the Applicable March 15 shall be reduced by such excess (beginning with
the installment first payable after the Applicable March 15 and continuing with the next succeeding installments until the aggregate reduction equals such excess). The right to payment of the installment amounts pursuant to this Section
6.1(b)(A) shall be treated as a right to a series of separate payments for purposes of section 409A of the Code. 
 (B)
During the portion, if any, of the 12-month period following the Date of Termination that Executive elects to continue coverage for Executive and Executive’s spouse and eligible dependents, if any, under
the Company’s group health plans under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), and/or sections 601 through 608 of the Employee Retirement Income Security Act of 1974, as amended,
the Company shall promptly reimburse Executive on a monthly basis for the entire amount Executive pays to effect and continue such coverage; provided, however, that such monthly reimbursement shall in no event exceed the monthly amount that would be
charged by the Company to effect and continue COBRA coverage similar in amount and type of coverage Executive was receiving from the Company immediately prior to the Date of Termination. Notwithstanding the preceding provisions of this clause (B),
if the provision of the benefit described in such clause cannot be provided in the manner described in such clause without penalty, tax or other adverse impact on the Company, then the Company and Executive shall negotiate in good faith to determine
an alternative manner in which the Company may provide a substantially equivalent benefit to Executive without such adverse impact on the Company. 

  
 9 

 (c) Notwithstanding the time of payment provisions of Sections 6.1(a) and
(b) above, if Executive is a specified employee (as such term is defined in section 409A of the Code and as determined by the Company in accordance with any method permitted under section 409A of the Code) and the payment of the amount
described in such Section would be subject to additional taxes and interest under section 409A of the Code because the timing of such payment is not delayed as provided in section 409A(a)(2)(B)(i) of the Code and the regulations thereunder, then
such amount shall be accumulated and paid (without interest) in a lump sum within five business days after the Section 409A Payment Date. All subsequent payments, if any, shall be paid in the manner otherwise specified herein.

enticed away from the Company or any of its affiliates any person or entity who or which is a customer of any of such entities during the period during which Executive is employed by the Company. 

(d) Notwithstanding the above-referenced limitations in Sections 7.2(a) and 7.2(c)(ii) above, such limitations shall not apply
in those portions of the Restricted Area located within the State of Oklahoma. Instead, Executive agrees that the restrictions on Executive’s activities within those portions of the Restricted Area located within the State of Oklahoma (in
addition to those restrictions set forth in Section 7.2(c)(i) and Article V above) shall be as follows: during the Prohibited Period, Executive will not directly or indirectly solicit the sale of goods, services, or a combination of goods and
services from the established customers of Nine Energy or its subsidiaries. 
 (e) Before accepting employment with any other
person or entity while employed by the Company or during the Prohibited Period, Executive will inform such person or entity of the restrictions contained in this Article VII. 

7.3 Relief. Executive and the Company agree and acknowledge that the limitations as to time, geographical area and scope
of activity to be restrained as set forth in Section 7.2 are reasonable in all respects and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company. Executive and the Company also
acknowledge that money damages would not be sufficient remedy for any breach of this Article VII by Executive, and the Company or its affiliates shall be entitled to enforce the provisions of this Article VII by terminating payments then owing to
Executive under this Agreement or otherwise and to specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Article VII but shall
be in addition to all remedies available at law or in equity, including the recovery of damages from Executive and Executive’s agents. However, if it is determined that Executive has not committed a breach of this Article VII, then the Company
shall resume the payments and benefits due under this Agreement and pay to Executive all payments that had been suspended pending such determination. Each affiliate of the Company shall be a third-party beneficiary of Executive’s commitments
and obligations under this Article VII. 
 7.4 Reasonableness; Enforcement. Executive hereby represents to the Company
that Executive has read and understands, and agrees to be bound by, the terms of this Article VII. Executive acknowledges that the geographic scope and duration of the covenants contained in this Article VII are the result of arm’s-length bargaining and are fair and reasonable in light of (a) the nature and wide geographic scope of the Company’s and its affiliates’ operations of the Business, (b) Executive’s
level of control over and contact with the Company’s and Nine Energy’s business in all jurisdictions in which it is conducted, (c) the fact that the Business is conducted by the Company or its affiliates throughout the Restricted
Area, (d) the fact that 

  
 12 

 
Executive constitutes managerial and executive personnel of the Company and Nine Energy who will be materially associated with the Company’s and Nine Energy’s goodwill, and (e) the
amount of Confidential Information that Executive is receiving in connection with the performance of Executive’s duties hereunder. It is the desire and intent of the parties that the provisions of this Article VII be enforced to the fullest
extent permitted under applicable Legal Requirements, whether now or hereafter in effect and therefore, to the extent permitted by applicable Legal Requirements, Executive and the Company hereby waive any provision of applicable Legal Requirements
that would render any provision of this Article VII invalid or unenforceable. 
 7.5 Reformation. The Company and
Executive agree that the foregoing restrictions are reasonable in all respects and that any breach of the covenants contained in this Article VII would cause irreparable injury to the Company and Nine Energy. Executive understands that the foregoing
restrictions may limit Executive’s ability to engage in certain businesses anywhere in the Restricted Area during the Prohibited Period, but acknowledges that Executive will receive sufficient consideration from the Company to justify such
restriction. Further, Executive acknowledges that Executive’s skills are such that Executive can be gainfully employed in non-competitive employment, and that the agreement not to compete will not prevent
Executive from earning a living. Nevertheless, if any of the aforesaid restrictions are found by a court of competent jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for
the restrictions herein set forth to be modified by the court making such determination so as to be reasonable and enforceable and, as so modified, to be fully enforced. By agreeing to this contractual modification prospectively at this time, the
Company and Executive intend to make this provision enforceable under the law or laws of all applicable states, provinces and other jurisdictions so that the entire agreement not to compete and this Agreement as prospectively modified shall remain
in full force and effect and shall not be rendered void or illegal. Such modification shall not affect the payments made to Executive under this Agreement. 

ARTICLE VIII 
 DISPUTE
RESOLUTION 
 8.1 Arbitration. All claims or disputes between Executive and the Company or its parents,
subsidiaries and affiliates (including, without limitation, claims relating to the validity, scope, and enforceability of this Article VIII and claims arising under any federal, state or local law regarding the terms and conditions of employment or
prohibiting discrimination in employment or governing the employment relationship in any way) shall be submitted for final and binding arbitration in Houston, Texas in accordance with the then-applicable rules for resolution of employment disputes
of the American Arbitration Association (“AAA”). The arbitration shall be conducted by a single arbitrator chosen pursuant to the then-applicable rules for resolution of employment disputes of the AAA, and the Company shall
bear the costs of such arbitration. For the avoidance of doubt, the Company’s assumption of costs referenced in the previous sentence applies to the costs of the AAA only, and does not include attorney or expert fees or other fees or costs
incurred by Executive. The arbitrator shall apply the substantive law of the State of Texas (excluding Texas choice-of-law principles that might call for the application
of some other state’s law), or federal law, or both as applicable to the claims asserted. The results of the arbitration and the decision of the arbitrator will be final and binding on the 

  
 13 

 
parties and each party agrees and acknowledges that these results shall be enforceable in a court of law. No demand for arbitration may be made after the date when the institution of legal or
equitable proceedings based on such claim or dispute would be barred by the applicable statute(s) of limitations. In the event either party must resort to the judicial process to enforce the provisions of this Agreement, the award of an arbitrator
or equitable relief granted by an arbitrator, the party successfully seeking enforcement shall be entitled to recover from the other party all costs of such litigation including, but not limited to, reasonable attorneys’ fees and court costs.
To the fullest extent permitted by law, all proceedings conducted pursuant to this agreement to arbitrate, including any order, decision or award of the arbitrator, shall be kept confidential by the parties. Notwithstanding the foregoing, Executive
and the Company further acknowledge and agree that a court of competent jurisdiction residing in Houston, Texas shall have the power to maintain the status quo pending the arbitration of any dispute under this Article VIII, and this Article VIII
shall not require the arbitration of any application for emergency, temporary or preliminary injunctive relief (including temporary restraining orders) by either party pending arbitration, including, without limitation, any application for
emergency, temporary or preliminary injunctive relief for any claim arising out of Article V or Article VII of this Agreement; provided, however, that the remainder of any such dispute beyond the application for such emergency, temporary or
preliminary injunctive relief shall be subject to arbitration under this Article VIII. THE PARTIES ACKNOWLEDGE THAT, BY SIGNING THIS AGREEMENT, THEY ARE KNOWINGLY AND VOLUNTARILY WAIVING ANY RIGHTS THAT THEY MAY HAVE TO A JURY TRIAL OR, EXCEPT AS
EXPRESSLY PROVIDED HEREIN, A COURT TRIAL OF ANY CLAIM THAT IS SUBJECT TO THIS ARTICLE VIII.

and, as applicable, its Affiliates. Notwithstanding the foregoing, the Parties acknowledge and agree that Executive may (a) engage in and manage Executive’s passive personal investments, and (b) engage in charitable and civic
activities; provided, however, that such activities described in clauses (a) and (b) above shall be permitted only so long as such activities do not materially conflict with the business and affairs of the Company or its Affiliates or

Executive acknowledges and agrees that Executive owes a fiduciary duty of loyalty to the Company. In keeping with this duty, Executive shall make full disclosure to the Company of all business opportunities pertaining to the Company’s business
and shall not appropriate for Executive’s own benefit business opportunities concerning the subject matter without first giving the Company and its Affiliates the opportunity to act on such opportunity, and in no event in breach of any
provision of this Agreement. 
 ARTICLE III 

TERM AND TERMINATION OF EMPLOYMENT 

3.1 Term. Unless sooner terminated pursuant to other provisions of this Agreement, the Company agrees to employ Executive
for the period beginning on the Effective Date and ending on the third anniversary of the Effective Date (the “Initial Expiration Date”); provided, however, that beginning on the Initial Expiration Date, and on
each anniversary of the Initial Expiration Date thereafter, if Executive’s employment under this Agreement has not been terminated pursuant to Section 3.2 or Section 3.3, then said term of
employment shall automatically be extended for an additional one-year period, unless, on or before the date that is 60 days prior to the first day of any such extension period, either Party gives written
notice to the other Party that no such automatic extension shall occur, in which case the term of employment shall terminate as of the Initial Expiration Date or the anniversary of the Initial Expiration Date immediately following the giving of such
notice, as applicable. 
 3.2 Company’s Right to Terminate. Notwithstanding the
provisions of Section 3.1, Executive’s employment with the Company shall automatically terminate upon the death of Executive, and the Company shall have the right to terminate Executive’s employment under this
Agreement at any time for any of the following reasons by providing Executive with a Notice of Termination:

Executive’s becoming incapacitated by accident, sickness or other circumstance that renders him mentally or physically incapable of performing the duties and services required of him hereunder on a full-time basis for a period of at least 120
consecutive days or for a period of at least 180 days (whether or not consecutive) during any consecutive 12-month period;

3.3 Executive’s Right to Terminate. Notwithstanding the provisions of
Section 3.1, Executive shall have the right to terminate Executive’s employment under this Agreement at any time for any of the following reasons by providing the Company with a Notice of Termination (provided that in
the case of a termination of employment by Executive pursuant to Section 3.3(b), the Date of Termination specified in the Notice of Termination shall not be less than 60 nor more than 90 days from the date such Notice of Termination is given,
provided, that, the Company may require a Date of Termination earlier than that specified in the Notice of Termination (and, if such earlier Date of Termination is so required, it shall not change the basis for Executive’s termination nor be
construed or interpreted as a termination of employment pursuant to Section 3.2)): 
 (a) for Good
Reason; or 
 (b) for any other reason whatsoever or for no reason at all, in the sole discretion of Executive. 

3.4 Deemed Resignations. Unless otherwise agreed to in writing by the Parties prior to the termination of Executive’s
employment, any termination of Executive’s employment shall constitute (a) an automatic resignation of Executive as an officer of the Company and each Affiliate of the Company and (b) an automatic resignation of Executive from the
Board (if applicable), from the board of directors or similar governing body of the Company or any Affiliate of the Company and from the board of directors or similar governing body of any Person in which the Company or any Affiliate holds any
interests and with respect to which board or similar governing body Executive serves as the Company’s or such Affiliate’s designee or other representative. 

3.5 Meaning of Termination of Employment. For all purposes of this Agreement, Executive shall be considered to have
terminated employment with the Company when Executive incurs a “separation from service” with the Company within the meaning of section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder. 

ARTICLE IV 

COMPENSATION AND BENEFITS 

4.1 Base Salary. During the term of this Agreement, Executive shall receive an annualized base salary of $250,000 (the
“Base Salary”). Executive’s Base Salary shall be paid in substantially equal installments in accordance with the Company’s standard policy regarding payment of compensation to similarly situated employees in effect
from time to time, but no less frequently than monthly. 

  
 5 

 4.2 Bonuses. Executive shall be eligible to participate in the annual cash
incentive bonus program of the Company, which will provide for a potential annual, calendar-year bonus of up to 200% of Executive’s Bases Salary based on, and subject to the satisfaction of, criteria determined in the sole discretion of the
Company (the “Annual Bonus”), it being understood that the target bonus at planned or targeted levels of performance and the actual amount of each Annual Bonus (if any) shall be determined in the sole discretion of the
Company by the Board. Executive will be entitled to receive payment of such Annual Bonus (if any) only if Executive is employed by the Company on the date of payment, except as otherwise provided by Section 6.1(a) or Section 6.1(b) of
this Agreement. The Annual Bonus shall be payable not later than March 31 of the year immediately following the calendar year to which the Annual Bonus relates, except as otherwise provided by Section 6.1(a) or Section 6.1(b). In
addition to the Annual Bonus, Executive shall be entitled to an annual guaranteed bonus of $50,000 (the “Guaranteed Bonus”). The Guaranteed Bonus shall be prorated for any partial calendar year based on a fraction, the
numerator of which shall be the number of days employed during the calendar year to which the Guaranteed Bonus relates, and the denominator of which shall be 365. The Guaranteed Bonus shall be payable not later than March 15 of the year
immediately following the calendar year to which such Guaranteed Bonus relates, except as otherwise provided by Section 6.1(a) or Section 6.1(b) of this Agreement. 

4.3 Other Benefits. During Executive’s employment hereunder, and subject to the terms and conditions of the
applicable benefit plans and programs in effect from time to time, Executive shall be eligible to participate in all benefit plans and programs of the Company, including improvements or modifications of the same, which are now, or may hereafter be,
available to similarly situated executive employees of the Company. The Company shall not, however, by reason of this Section 4.3, be obligated to institute, maintain, or refrain from changing, amending, or discontinuing,
any such benefit plan or program, so long as such changes are similarly applicable to similarly situated employees generally. 
 4.4
Expenses. The Company shall reimburse Executive for all reasonable business expenses incurred by Executive in performing services hereunder, including all expenses of travel and living expenses while away from home on business or
at the request of and in the service of the Company; provided that in each case such expenses are incurred and accounted for in accordance with the policies and procedures established by the Company. Any such reimbursement of expenses shall
be made by the Company upon or as soon as practicable following receipt of supporting documentation reasonably satisfactory to the Company (but in any event not later than the close of Executive’s taxable year following the taxable year in
which the expense is incurred by Executive); provided, however, that, upon Executive’s termination of employment with the Company, in no event shall any additional reimbursement be made prior to the Section 409A Payment Date to the
extent such payment delay is required under section 409A(a)(2)(B)(i) of the Code. In no event shall any reimbursement be made to Executive for such fees and expenses after the later of (a) the first anniversary of the date of Executive’s
death or (b) the date that is five years after the date of Executive’s termination of employment with the Company (other than by reason of Executive’s death).

Affiliates. 
 ARTICLE V 

PROTECTION OF INFORMATION 

5.1 Disclosure to and Property of the Company. For purposes of this Article V, the term “the Company”
shall include the Company and any of its Affiliates, and any reference to “employment” or similar terms shall include a director and/or consulting relationship. All Confidential Information, including, without limitation, all intellectual
property rights therein, is, and shall be, the sole and exclusive property of the Company. Moreover, all documents, videotapes, presentations, brochures, drawings, memoranda, notes, records, files, correspondence, manuals, models, specifications,
computer programs, email, voice mail, electronic databases, maps, drawings, architectural renditions, models and all other writings or materials of any type embodying any of such Confidential Information or the Company’s ideas, concepts,
improvements, discoveries, inventions and other similar forms of expression (collectively, “Work Product”) are and shall be the sole and exclusive property of the Company. Executive agrees to perform all actions reasonably
requested by the Company to establish and confirm such exclusive ownership. Upon termination of Executive’s employment with the Company, for any reason, Executive promptly shall deliver all Confidential Information and Work Product, and all
copies thereof, to the Company. 
 5.2 Disclosure to Executive. During Executive’s employment hereunder, the
Company shall disclose to Executive and place Executive in a position to have access to or develop Confidential Information. Executive acknowledges and agrees that Executive will be entrusted with business opportunities of the Company and shall be
in a position to develop business goodwill on behalf of the Company during Executive’s employment hereunder. 
 5.3 No
Unauthorized Use or Disclosure. Executive agrees that Executive will not, at any time during or after Executive’s employment with the Company, make any unauthorized disclosure of, and Executive shall not remove from the Company premises
or other authorized premises, Confidential Information or Work Product of the Company, or with respect to any Confidential Information or Work Product of the Company (excluding the Company’s Affiliates, except to the extent such Confidential
Information or Work Product of the Company’s Affiliate is disclosed or provided to Executive) make any use thereof, except, in each case, in the carrying out of Executive’s responsibilities hereunder. Executive shall have no obligation
hereunder to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by law; provided, however, that in the event disclosure is required by applicable law and Executive is making such
disclosure, Executive shall provide the Company with prompt notice of such requirement, and shall use Executive’s reasonable best efforts to give such notice prior to making any such disclosure, so that the Company may seek an appropriate
protective order. Executive agrees to deliver to the Company, at any time during the term of employment when requested by the Company and upon the termination of such employment, all Confidential Information that Executive may possess or control.
Executive agrees that all Confidential Information of the Company (whether now or hereafter existing) conceived, 

  
 7 

 
discovered or made by Executive during the period of Executive’s employment by the Company exclusively belongs to the Company (and not to Executive), and upon request by the Company for
specified Confidential Information, Executive will promptly disclose such Confidential Information to the Company and perform all actions reasonably requested by the Company to establish and confirm such exclusive ownership. Affiliates of the
Company shall be third-party beneficiaries of Executive’s obligations under this Article V. 
 5.4 Ownership by the
Company. If, during Executive’s employment by the Company, Executive creates any work of authorship fixed in any tangible medium of expression that is the subject matter of copyright (such as videotapes, written presentations, computer
programs, e-mail, voice mail, electronic databases, drawings, maps, architectural renditions, models, manuals, brochures, or the like) relating to the Business (as defined in
Article VII), whether such work is created solely by Executive or jointly with others (whether during business hours or otherwise, whether patentable or not and whether on the Company’s premises or otherwise),
including, without limitation, any Work Product, the Company shall be deemed the author of such work if the work is prepared by Executive in the scope of Executive’s employment; or, if the work is not prepared by Executive within the scope of
Executive’s employment but is specially ordered from Executive by the Company as a contribution to a collective work, as a part of a motion picture or other audiovisual work, as a translation, as a supplementary work, as a compilation, or as an
instructional text, then the work shall be considered to be work made for hire and the Company shall be the author of the work. If such work is neither prepared by Executive within the scope of Executive’s employment nor a work specially
ordered from Executive that is deemed to be a work made for hire during Executive’s employment by the Company, then Executive hereby agrees to assign, and by these presents does assign, to the Company all of Executive’s worldwide right,
title, and interest in and to such work and all rights of copyright therein. 
 5.5 Assistance by Executive. During the
period of Executive’s employment by the Company, Executive shall assist the Company and its nominee, at any time, in the protection of the Company’s worldwide right, title and interest in and to Confidential Information and Work Product,
including, without limitation, all intellectual property rights therein, and the execution of all formal assignment documents requested by the Company or its nominee(s) and the execution of all lawful oaths and applications for patents and
registration of copyright in the United States and foreign countries. After Executive’s employment with the Company terminates, from time to time at the request and expense of the Company, Executive shall assist the Company or its
nominee(s) (i) in the protection of the Company’s worldwide right, title and interest in and to Confidential Information and Work Product, subject to the payment for services at a rate of $100 per hour and provided such assistance does not
unreasonably disrupt Executive’s obligation to his then current employer or other service recipient, and (ii) the execution of all formal assignment documents requested by the Company or its nominee and the execution of all lawful oaths
and applications for patents and registration of copyrights in the United States and foreign countries. 
 5.6 Remedies.
Executive acknowledges that money damages would not be a sufficient remedy for any breach of this Article V by Executive, and the Company shall be entitled to enforce the provisions of this Article V by terminating payments then owing
to Executive under this Agreement or otherwise and to specific performance and injunctive relief as 

  
 8 

 
remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Article V but shall be in addition to all remedies
available to the Company at law or in equity, including, without limitation, the recovery of damages from Executive and Executive’s agents. However, if it is determined that Executive has not committed a breach of this Article V, then
the Company shall resume the payments and benefits due under this Agreement and pay to Executive and Executive’s spouse, if applicable, all payments and benefits that had been suspended pending such determination. 

5.7 Statements by Executive. Executive shall refrain, both during and after the termination of Executive’s employment
relationship with the Company, from publishing any oral or written statements about the Company or any of the Company’s directors, managers, officers, employees, consultants, agents or representatives that (a) are slanderous, libelous or
defamatory, or (b) place the Company or any of the Company’s directors, managers, officers, employees, consultants, agents or representatives in a false light before the public; provided, that nothing in this
Section 5.7 shall prevent the Company from pursuing all remedies available to it in connection with this Agreement or any other agreement or obligation that the Company or its Affiliates may have with or to Executive or his
Affiliates, including statements in public court documents and related pleadings. The Company may seek to have a violation or threatened violation of this prohibition enjoined by the courts. The rights afforded the Company under this provision are
in addition to any and all rights and remedies otherwise afforded by law. 
 ARTICLE VI

other executives of the Company of a similar seniority level that remain employed by the Company on the normal payment date of such annual bonus (but in no event later than December 31 of the year immediately following the calendar year to
which such Annual Bonus relates), and (v) the Guaranteed Bonus for the calendar year in which the Date of Termination occurs, which amount shall be prorated for any partial calendar year and shall be paid not later than March 15 of the
calendar year immediately following the calendar year in which the Date of Termination occurs. Executive shall be deemed to “earn” the Annual Bonus for solely purposes of this Article VI if Executive remained continuously employed
by the Company or its Affiliates through December 31 of the calendar year to which such Annual Bonus relates. 

  
 9 

 (b) If Executive’s employment hereunder shall terminate by
(x) expiration of the then-existing term due to notice of non-renewal duly given by the Company to Executive in accordance with Section 3.1, (y) by action of the Company pursuant
to Section 3.2(c) or (z) by action of Executive pursuant to Section 3.3(a), then all compensation and all benefits to Executive hereunder shall terminate contemporaneously with such termination of employment, except that: 

(i) Executive shall be entitled to receive the compensation and benefits described in clauses (i) through (iii) of
Section 6.1(a); 
 (ii) Executive shall be entitled to receive any unpaid Annual Bonus earned by Executive prior to
the Date of Termination, which payment will be made not later than the date the annual bonus, if any (for the same calendar year as relates to such earned and unpaid Annual Bonus), is paid to the other executives of the Company of a similar
seniority level that remain employed by the Company on the normal payment date of such annual bonus (but in no event later than December 31 of the year immediately following the calendar year to which such Annual Bonus relates); 

(iii) Executive shall be entitled to receive the Guaranteed Bonus (prorated for any partial calendar) for the calendar year in
which the Date of Termination occurs, which payment will be made not later than March 15 of the calendar year immediately following the calendar year in which the Date of Termination occurs; and 

(iv) if, on the Date of Termination, the Company does not have a right to terminate Executive’s employment under
Section 3.2(a) or Section 3.2(b) and subject to Executive’s delivery, on or before the Release Expiration Date, and non-revocation in the time provided to do so, of an executed release in a
form reasonably satisfactory to the Company (which shall release and discharge the Company, its Affiliates, and their respective stockholders, officers, directors, managers, members, partners, employees, agents, representatives, benefit plans (and
the trustees and fiduciaries of such plans) and other affiliated Persons from any and all claims and causes of action of any kind or character, including, without limitation, all claims and causes of action arising out of Executive’s employment
with the Company or its Affiliates or the termination of such employment) (the “Release”), Executive shall receive the following compensation and benefits from the Company: 

(A) the Company shall pay to Executive an amount equal to eighteen (18) months of Executive’s Base Salary as of the
Date of Termination, which amount shall be divided into eighteen (18) substantially equal monthly installments. On the last day of the month that includes the date that is sixty (60) 

  
 10 

 
days after the Date of Termination, the Company shall pay to Executive, without interest, a number of such installments equal to the number of such installments that would have been paid during
the period beginning on the Date of Termination and ending on such last day of the month had the installments been paid on a monthly basis commencing on the Company’s monthly payroll date coincident with or next following the Date of
Termination, and each of the remaining installments shall be paid on a monthly basis thereafter; provided, however, that to the extent, if any, that the aggregate amount of such installments that would otherwise be paid pursuant to the
preceding provisions of this clause (A) after March 15 of the calendar year following the calendar year in which the Date of Termination occurs (the “Applicable March 15”) exceeds
the maximum exemption amount under Treasury Regulation Section 1.409A-1(b)(9)(iii)(A), then such excess shall be paid on the Applicable March 15 (or the first business day preceding the Applicable
March 15 if the Applicable March 15 is not a business day) and such installments payable after the Applicable March 15 shall be reduced by such excess (beginning with the installment first payable after the Applicable March 15
and continuing with the next succeeding installments until the aggregate reduction equals such excess). The right to payment of the installment amounts pursuant to this paragraph shall be treated as a right to a series of separate payments for
purposes of section 409A of the Code; and 
 (B) during the portion, if any, of the eighteen (18) month period following
the Date of Termination that Executive elects to continue coverage for Executive and Executive’s spouse and eligible dependents, if any, under the Company’s group health plans under the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended (COBRA), and/or sections 601 through 608 of the Employee Retirement Income Security Act of 1974, as amended, similar in the amounts and types of coverage provided by the Company to Executive prior to the Date of Termination, the
Company shall promptly reimburse Executive on a monthly basis for the entire amount Executive pays to effect and continue such coverage. Notwithstanding the preceding provisions of this paragraph (B), if the provision of the benefit described in
such paragraph cannot be provided in the manner described in such paragraph without penalty, tax or other adverse impact on the Company, then the Company and Executive shall negotiate in good faith to determine an alternative manner in which the
Company may provide a substantially equivalent benefit to Executive without such adverse impact on the Company. 
 (c)
Notwithstanding the time of payment provisions of Sections 6.1(a) and (b) above, if Executive is a specified employee (as such term is defined in section 409A of the Code and as determined by the Company in accordance with any method
permitted under section 409A of the Code) and the payment of the amount described in such Section would be subject to additional taxes and interest under section 409A of the Code because the timing of such payment is not delayed as provided in
section 409A(a)(2)(B)(i) of the Code and the regulations thereunder, then such amount shall be accumulated and paid (without interest) in a lump sum within five business days after the Section 409A Payment Date. All subsequent payments, if any,
shall be paid in the manner otherwise specified herein.

 ARTICLE VII 

NON-COMPETITION AGREEMENT 

7.1 Definitions. As used in this Article VII, the following terms shall have the following meanings: 

“Business” means (a) for the period of time in which Executive is employed by the Company or any of its
Affiliates, the provision and sale of the products and services provided by the Company or its Affiliates during such period and other products and services that are functionally equivalent to the foregoing and (b) for the period of time within
the Prohibited Period in which Executive is not employed by the Company or any of its Affiliates, the provision and sale of the products and services that were provided by the Company or its Affiliates during the period of time in which Executive
was employed by the Company or its Affiliates, in each case under clauses (a) and (b), excluding the provision of and sale of products and services as part of any business, product or service line, or division in which Executive was not
directly involved as a manager or supervisor during such employment. The Business includes for purposes of both clauses (a) and (b), without limitation, the provision of equipment and services, including primary downhole cementing and related
ancillary services, used in remedial cementing, maintenance and workover of wells for the production of oil and natural gas. 

“Prohibited Period” means the period during which Executive is employed by the Company, any of its Affiliates or any

“Restricted Area” means (a) the geographic areas set forth on Exhibit A hereto and (b) any other
geographical areas in which the Company and its Affiliates engage in the Business, and for which Executive has material responsibilities, during the period that Executive is employed hereunder. 

7.2 Non-Competition; Non-Solicitation.
Executive and the Company agree to the non-competition and non-solicitation provisions of this Article VII to protect the trade secrets and other Confidential
Information of the Company disclosed or entrusted to Executive by the Company or its Affiliates or created or developed by Executive for the Company, to protect the goodwill of the Company and as a condition of Executive’s employment with the
Company. 
 (a) Subject to the exceptions set forth in Section 7.2(b) below, Executive covenants and agrees from the
Effective Date up to the Date of Termination, other than on behalf of the Company or any of its Affiliates, Executive will refrain from carrying on or engaging directly or indirectly in the Business, and that after the Date of Termination and prior
to the expiration of the Prohibited Period, other than on behalf of the Company or any of its Affiliates, Executive will refrain from carrying on or engaging directly or indirectly in the Business in the Restricted Area. Executive further agrees and
covenants that, because the following conduct would effectively constitute carrying on or engaging 

  
 12 

 
in the Business, Executive will not, and Executive will cause Executive’s Affiliates not to, in the applicable area during the Prohibited Period, other than on behalf of the Company or its
Affiliates, directly or indirectly, (A) own, manage, operate, join, become an employee of, control or participate in any business or Person which engages in the Business or (B) loan money to or sell or lease equipment related to the
Business to any business or Person that engages in the Business. 
 (b) Notwithstanding the restrictions contained in
Section 7.2(a), Executive may own an aggregate of not more than 3% of (i) the outstanding stock or other equity securities of any class of any corporation or other entity engaged in the Business, if such stock or equity securities are
listed on a national securities exchange or regularly traded in the over-the-counter market by a member of a national securities exchange or (ii) of the outstanding
limited partnership interests or other passive equity interests in a private investment fund entity not Affiliated with Executive that invests or owns interest or may invest or own interests in any corporation or other entity engaged in the
Business, without violating the provisions of Section 7.2(a), in each case, provided that neither Executive nor any of Executive’s Affiliates has the power, directly or indirectly, to control or direct the management or affairs of any
such corporation or entity and is not involved in the management of such corporation or entity. 
 (c) Executive further
expressly covenants and agrees that, other than on behalf of the Company or its Affiliates: (i) prior to the Date of Termination, Executive will not, and Executive will cause Executive’s Affiliates not to, canvass, solicit, approach or
entice away, or cause to be canvassed, solicited, approached or enticed away, any customer of the Company or its Affiliates that was a customer or supplier of the Company or the Business during the period during which Executive is employed by the
Company or any of its Affiliates for the purpose of engaging in the Business; and (ii) after the Date of Termination and prior to the expiration of the Prohibited Period, Executive will not, and Executive will cause Executive’s Affiliates
not to, within the Restricted Area, canvass, solicit, approach or entice away, or cause to be canvassed, solicited, approached or enticed away, any customer of the Company or its Affiliates that was a customer, consultant or supplier of the Company
or the Business during the period during which Executive is employed by the Company or any of its Affiliates for the purpose of engaging in the Business. 

(d) Executive further covenants and agrees that during the Prohibited Period, Executive will not, and Executive will cause
Executive’s Affiliates not to, engage or employ, or solicit or contact with a view to the engagement or employment of, any Person who is an officer, director, manager or employee of the Company or its Affiliates. 

(e) Notwithstanding the foregoing, the above-referenced limitations in Section 7.2(a) and Section 7.2(c) shall
not apply in those portions of the Restricted Area located within the State of Oklahoma. Instead, Executive agrees that, in addition to the limitations in Article V and Section 7.2(d), the restrictions on Executive’s
activities within those portions of the Restricted Area located within the State of Oklahoma shall be as follows: during the Prohibited Period, Executive will not directly solicit the sale of goods, services, or a combination of goods and services
from the established customers of the Company or its Affiliates, except when acting on behalf of the Company or its Affiliates. 

  
 13 

 7.3 Relief. The Parties agree that the any breach of the covenants contained
in this Article VII would cause irreparable injury to the Company. The Parties also acknowledge that money damages may not be sufficient remedy for any breach of this Article VII by Executive, and the Company and its Affiliates shall
be entitled to seek enforce the provisions of this Article VII by terminating payments then owing to Executive under this Agreement or otherwise and obtaining specific performance and injunctive relief as remedies for such breach or any
threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Article VII but shall be in addition to all remedies available at law or in equity, including, without limitation, the recovery of damages from
Executive and Executive’s agents. 
 7.4 Reasonableness; Enforcement. Executive hereby represents to the Company
that Executive has read and understands the terms of this Article VII. Executive acknowledges that Executive is an executive-level employee and that the geographic scope and duration of the covenants contained in this Article VII are
the result of arm’s-length bargaining and are fair and reasonable in light of (a) Executive’s level of control over and contact with the Business conducted by the Company and its Affiliates in
all jurisdictions in which it is conducted, which includes the entire Restricted Area, and (b) the amount of consideration and Confidential Information that Executive is receiving in connection with the performance of Executive’s duties
hereunder and the goodwill that Executive has built and will continue to help build during Executive’s employment hereunder. It is the desire and intent of the Parties that the provisions of this Article VII be enforced to the fullest
extent permitted under applicable legal requirements, whether now or hereafter in effect and therefore, to the extent permitted by applicable legal requirements, the Parties hereby waive any provision of applicable legal requirements that would
render any provision of this Article VII invalid or unenforceable. 
 7.5 Reformation. Executive understands that
the foregoing restrictions may limit Executive’s ability to engage in certain businesses during the Prohibited Period. If any of the aforesaid restrictions are found by a court of competent jurisdiction or arbitrator to be unreasonable, or
overly broad as to geographic area or time, or otherwise unenforceable, the Parties intend for the restrictions herein set forth to be modified by the court or arbitrator making such determination so as to be reasonable and enforceable and, as so
modified, to be fully enforced. By agreeing to this contractual modification prospectively at this time, the Parties intend to make this provision enforceable under the law or laws of all applicable states and other applicable jurisdictions so that
the entire agreement not to compete or to solicit other employees or customers and this Agreement as prospectively modified shall remain in full force and effect and shall not be rendered void or illegal. 

ARTICLE VIII 
 DISPUTE
RESOLUTION 
 8.1 Arbitration. Any and all claims or disputes between the Parties or their respective
Affiliates (including, without limitation, claims or disputes regarding the validity, scope, and enforceability of this Section 8.1 and claims arising under any federal, state or local law prohibiting discrimination in
employment or governing the employment relationship in any 

  
 14 

 
way) shall be submitted for final and binding arbitration before a single arbitrator in accordance with the then-applicable rules for resolution of employment disputes of the American Arbitration
Association (“AAA”). The arbitration proceeding shall be held in Houston, Texas. The arbitrator shall issue a reasoned decision and apply the substantive law of the State of Texas (without regard to conflicts of law
principles thereof). The results of the arbitration and the decision of the arbitrator will be final and binding on the Parties and each Party agrees and acknowledges that these results shall be enforceable in a court of law. No demand for
arbitration may be made after the date when the institution of legal or equitable proceedings based on such claim or dispute would be barred by the applicable statute of limitations. In the event either Party must resort to the judicial process to
enforce the provisions of this Agreement, the award of an arbitrator or equitable relief granted by an arbitrator, the Party seeking enforcement, if successful on the merits, shall be entitled to recover from the other Party all costs of litigation
including, but not limited to, reasonable attorneys’ fees and court costs. All proceedings conducted pursuant to this agreement to arbitrate, including, without limitation, any order, decision or award of the arbitrator, shall be kept
confidential by all Parties. Notwithstanding the foregoing, the Parties acknowledge and agree that a court of competent jurisdiction shall have the power to maintain the status quo pending the arbitration of any dispute under this
Section 8.1, and this Section 8.1 shall not require the arbitration of an application for emergency or temporary injunctive relief by either Party pending arbitration; provided, however,
that the remainder of any such dispute beyond the application for emergency or temporary injunctive relief shall be subject to arbitration under this Section 8.1. THE PARTIES EXPRESSLY ACKNOWLEDGE AND AGREE THAT THEY
HAVE READ AND UNDERSTOOD THIS SECTION 8.1 AND THAT THEY ARE HEREBY KNOWINGLY AND VOLUNTARILY WAIVING THEIR RIGHT TO A JURY TRIAL.

9.4 Severability. If an arbitrator or court of competent jurisdiction determines that any provision of this Agreement is

(and in the case of an assignment by the Company to an Affiliate, such assignment shall not relieve the Company of its obligations hereunder) and shall be assignable by the Company to any such Affiliate or successor without the consent of Executive.
This Agreement is personal to Executive. Accordingly, except as provided in the first sentence of this Section 9.9, this 

  
 16 

 
Agreement, and the rights and obligations of the Parties hereunder, shall not be subject to voluntary or involuntary assignment, alienation or transfer, whether by operation of law or otherwise,
without the prior written consent of the other Party. Notwithstanding the foregoing, any payment owed to Executive hereunder after the date of Executive’s death shall be paid to Executive’s estate. 

9.10 Effect of Termination of Employment Relationship. This Section 9.10 and the provisions of

hereafter executed by the Company and Executive, including, without limitation, as provided in Section 6.2 and Section 6.8 of the Agreement and Plan of Merger by and among Nine, the Company and the other parties thereto, of even date
herewith (the “Merger Agreement”), or elsewhere in the Merger Agreement, 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 employment of Executive by the Company. Without limiting the scope of the preceding sentence, all understandings and agreements preceding the date of execution of

employment (including Executive’s compensation) with the Company or any of its Affiliates. For avoidance of doubt, this Section 9.11 shall not limit or restrict Executives rights under the Merger Agreement or any rights to indemnification
or advancement of expenses related thereto based on Executive’s status as an officer or director or manager (or comparable position) of the Company or any of its Affiliates under the respective organizational documents of the Company or its
Affiliates. 
 9.12 Modification; Waiver. Any amendment, modification to or waiver of this Agreement will be effective

 9.13 Actions by the Board. Any and all determinations or other
actions required of the Board hereunder shall be made by the members of the Board other than Executive if Executive is a member of the Board, and Executive shall not have any right to vote or decide upon any such matter. 

9.14 Executive’s Representations and Warranties. Executive represents and warrants to the Company that
(a) Executive does not have any agreements with Executive’s prior employers or any other Person that will prohibit Executive, after the Effective Date, from working for the Company or fulfilling Executive’s duties and obligations to
the Company pursuant to this Agreement and (b) Executive has complied with all duties imposed on Executive with respect to Executive’s former employers, and in the course of Executive’s employment for the Company, Executive will not

 9.15 Section 409A. Notwithstanding any provision in this Agreement to the
contrary, if any payment or benefit provided for herein would be subject to additional taxes and interest under section 409A of the Code if Executive’s receipt of such payment or benefit is not delayed until the Section 409A Payment Date, then
such payment or benefit shall not be provided to Executive (or Executive’s estate, if applicable) until the Section 409A Payment Date. The intent of the Parties is that payments and benefits under this Agreement comply with section 409A of
the Code and the regulations and guidance promulgated thereunder to the extent applicable (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement
shall be interpreted to be in compliance therewith. If Executive notifies the Company (with specificity as to the reason therefore) that Executive believes that any provision of this Agreement (or of any award of compensation, including equity
compensation, or benefits hereunder) would cause Executive to incur any additional tax or interest under Code Section 409A and the Company concurs with such belief or the Company independently makes such determination, the Company shall, after
consulting with Executive, use reasonable efforts to reform such provision to try to comply with Code Section 409A through good faith modifications to the minimum extent reasonably appropriate to comply with the requirements of Code
Section 409A to the extent applicable; provided, however, that in no event shall the Company have any liability to Executive for any taxes, interest, penalties or other costs or expenses incurred by Executive under or with respect to Code
Section 409A. To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and
economic benefit to Executive and the Company of the applicable provision without violating the provisions of Code Section 409A.
