AGREEMENT
TERMS:

 

1.
Term. The Company shall continue to

the other Party of his or its election not to renew this Agreement at least thirty (30) days prior to the last day of the then-current
Term. Executive’s employment hereunder shall be coterminous with the Term, and termination of Executive’s employment
and the Term shall be simultaneous.

 

    	 

    	 

    

 

2.
Duties as Executive of the Company. Subject
to this Agreement’s terms, Executive agrees to continue to serve the Company as its Chief Executive Officer, and to act
in the ordinary course of its business with all the powers and duties reasonably incident to the position(s) and such other responsibilities
or duties that may be from time to time assigned to Executive by the Board of Directors or the Company’s Chief Executive
Officer. Executive shall report to the Company’s Chief Executive Officer.

 

3.
Compensation and Related Matters.

 

(a)
Base Salary. Executive shall receive
an initial Base Salary (defined below) paid by the Company at the annual rate of $350,000 per year. Executive’s Base Salary
may be increased annually, effective on January 1 of each year beginning after the Effective Date, by an amount (if any) to be
determined by Eco-Stim, in its sole discretion. For purposes of this Agreement, “Base Salary” shall
mean Executive’s initial base salary or, the adjusted base salary then in effect at the time in question. The Base Salary
shall be paid, subject to all applicable withholdings and deductions, in accordance with the Company’s ordinary payroll
practices, as in effect from time to time.

 

(b)
Bonus Target. During each full calendar
year of the Term, Executive shall be eligible to receive an annual bonus in an amount, if any, to be determined by the Board of
Directors of Eco-Stim in its sole discretion, up to a maximum of one hundred and twenty five percent (125%) of Executive’s
Base Salary (the “Annual Bonus”). The amount of the Annual Bonus awarded, if any, shall be based on
achieving certain goals related to Company performance and objectives, established and measured by the Board of Directors of Eco-Stim,
in its sole discretion. To receive any Annual Bonus for a calendar year, Executive must be in “active working status”
at the time such Annual Bonus is scheduled to be paid, except as otherwise provided in Section 4, below. For purposes of this
Agreement, “active working status” means that the Termination Date has not occurred for any reason and
Executive has not been given notice of termination of his employment for any reason, and Executive has not resigned his employment
or given notice of his resignation, for any reason.

 

(c)
Expenses. Executive shall be entitled
to receive prompt reimbursement for all reasonable business expenses incurred by him, in accordance with the policies and procedures
established by the Company from time to time, in performing services under this Agreement and during his employment with the Company,
provided that Executive properly accounts for the expenses in accordance with Company policies. The amount of expenses eligible
for reimbursement during a calendar year shall not affect the expenses eligible for reimbursement in any other calendar year.
Reimbursement of eligible expenses shall be made on or before the last day of the calendar month following the calendar month
in which the expenses were incurred, provided appropriate requests with supporting documentation are timely submitted in accordance
with, or as otherwise provided in, the Company’s business expense reimbursement policy.

 

(d)
Benefits. During the Term, Executive
shall be eligible to participate in such retirement and employee benefit plans and arrangements that may be offered to the Company’s
senior executives, subject to and on a basis consistent with the terms, conditions, and overall administration of such plans and
arrangements, as amended from time to time. Nothing in this Agreement shall be deemed to confer upon Executive or any other person,
including any beneficiary, any rights under or with respect to any such plan or arrangement or to amend any such plan or arrangement,
and Executive and each other person, including any beneficiary, shall be entitled to look only to the express terms of any such
plan or arrangement for his or her rights thereunder. Nothing paid to Executive under any such plan or arrangement presently in
effect or made available in the future shall be deemed to be in lieu of the Base Salary and other benefits payable to Executive
pursuant to this Agreement.

 

    	2 

    	 

    

 

(e)
Vacation; Sick Leave; Holidays. Executive
shall be entitled to twenty (20) days of vacation and six (6) days of paid sick leave during each year of the Term, pro-rated
for partial years, exclusive of holidays. Executive shall insure that the scheduling of his vacation does not interfere with the
Company’s normal business operation. Vacation will accrue and may be forfeited as provided by the terms of the Company’s
policy governing vacation, as that policy is updated or revised from time to time in the Company’s sole discretion. For
purposes of this Section, weekends shall not count as Vacation days. Executive shall also be entitled to all paid holidays given
by the Company.

 

(f)
Proration. The Base Salary payable
to Executive hereunder in respect of any calendar year during which Executive is employed by the Company for less than the entire
year shall be prorated in accordance with the total number of calendar days in such calendar year during which he is so employed.

 

4.
Termination.

 

(a)
Definitions.

 

(1)
“Cause” shall mean:

 

(i)
Executive’s failure or refusal to substantially perform his material duties, responsibilities and/or obligations, which
failure or refusal to perform (if curable) is not cured to the reasonable satisfaction of the Company within thirty (30) days
following written notice from the Company to Executive setting forth the nature of the duties, responsibilities and/or obligations
that Executive has failed or refused substantially to perform; provided that Cause shall not include Executive’s failure
to so perform as a result of Executive’s incapacity due to his Disability;

 

(ii)
any act by Executive involving fraud, misrepresentation, theft, embezzlement, or dishonesty on a material matter in connection
with Executive’s employment with, or performance of his duties for, the Company; or

 

(iii)
conviction of Executive, or a plea by Executive, of guilty or nolo contendere to, an offense that is a (A) felony or (B)
misdemeanor that involves fraud; or

 

(iv)
material breach by Executive, of any of Executive’s obligations under Section 7 of this Agreement.

 

(2)
A “Disability” or
“Disabled” shall mean the inability of Executive to perform the essential functions of his position
at the Company by reason of any medically determinable physical or mental impairment that can be expected to result in death or
can be expected to last for a continuous period of not less than three (3) months. Executive shall be considered to have a Disability
(i) if he is determined to be totally disabled by the Social Security Administration or (ii) if he is determined to be disabled
under Eco-Stim’s long-term disability plan in which Executive participates and if such plan defines “disability”
in a manner that is consistent with the immediately preceding sentence.

 

    	3 

    	 

    

 

(3)
A “Good Reason”
shall mean that the occurrence of any of the following without Executive’s express written consent:

 

(i)
A material diminution in Executive’s Base Salary;

 

(ii)
A change in the location where Executive is expected or required to perform the majority of Executive’s job duties at the
time Executive executes this Agreement (“Base Location”) to a location that is more than twenty (20)
miles from the Base Location, except for travel reasonably required of Executive on the Company’s business;

 

(iii)
A substantial and adverse diminution in Executive’s duties, authority, responsibility or position with the Company; or

 

(iv)
Any breach by the Company of any material provision of this Agreement.

 

Executive’s
resignation for Good Reason shall be effective upon thirty (30) days’ advance written notice by Executive to the Company;
provided, however, that Good Reason shall cease to exist on the thirtieth (30th) day following the later of (x) the occurrence
of the fact, event, condition or other circumstance constituting or giving rise to Good Reason or (y) Executive’s knowledge
thereof. During such thirty (30) day notice period, the Company shall have a cure right, and Executive’s termination for
Good Reason will be effective upon expiration of such cure period only if the fact, event, condition or other circumstance constituting
or giving rise to Good Reason is not cured within such period. Any such termination by Executive shall not be deemed a breach
of the Agreement. If the Company timely cures the fact, event, condition or other circumstance giving rise to Good Reason for
Executive’s resignation, the notice of termination shall become null and void.

 

(4)
“Termination Date” shall
mean the date Executive’s employment with the Company and this Agreement terminates or is terminated for any reason. To
the extent that any payments or benefits under this Agreement are considered nonqualified deferred compensation subject to Section
409A (“Code Section 409A”) of the Internal Revenue Code (the “Code”), to the
extent necessary to avoid additional taxes under Code Section 409A, such termination of employment will only be considered a termination
of employment to the extent it also constitutes a “separation from service” for purposes of Code Section 409A.

 

(b)
Termination Without Cause or for Good Reason: Benefits. In
the event the Company involuntarily terminates Executive’s employment with the Company without Cause or Executive terminates
his employment with the Company for Good Reason (in each case, a “Termination Event”), this Agreement
shall terminate, and, in full satisfaction of the Company’s obligations under this Agreement, Executive shall receive the
following:

 

    	4 

    	 

    

 

(1)
Payment of accrued but unpaid Base Salary
and unreimbursed business expenses through the Termination Date in accordance with Sections 3(a) and 3(c).
The accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash within six (6) days following the Termination
Date. Unreimbursed business expenses shall be paid to Executive within the time period required by the Company’s business
expense reimbursement policy. In addition, Executive and/or his eligible dependents shall be eligible to continue group health
benefits at his or their expense as provided by applicable law. The payments and benefits set forth in this Section 4(b)(1)
are referred to, collectively, as the “Accrued Benefits”; and

 

(2)
Subject to Executive delivering to the Company
an executed Release (as defined below in Section 6) within the time period set forth in such Release, and Executive
not revoking such Release, payment of an amount equal to the Base Salary payable for one year (the “Severance Payment”),
at the rate in effect immediately before the Termination Event, payable in a lump sum on the first payroll date on or immediately
after the sixtieth (60th) day following the Termination Date, provided that the Release has become effective on such date in accordance
with its terms.

 

(3)

all unvested restricted stock and stock options granted to Executive prior to the Effective Date and outstanding on the Termination

(4)
Subject to Executive (x) delivering to the
Company an executed Release within the time period set forth in such Release, and Executive not revoking such Release, and (y)
timely electing medical benefit continuation pursuant to the COBRA, payment (or reimbursement of) the cost of medical benefit
continuation (on the same basis and at the same cost as such benefits are currently provided to executives of the Company) for
Executive and any covered dependents for up to eighteen (18) months or until Executive and/or his covered dependents are covered
by another company’s group health insurance, whichever is sooner; and provided, further, that if the Company determines
in good faith that its payment of such cost will result in the imposition of excise taxes or penalties on the Company and/or the
insurance carrier with respect to such medical benefits, then the Company shall not pay (or reimburse) such cost and the Company
shall provide an economically equivalent benefit or payment, to the extent that such benefit or payment is consistent with applicable
law and will not result in the imposition of such excise taxes or penalties. Executive covenants and agrees that if he becomes
eligible for coverage under another company’s group health insurance within eighteen (18) months of the Termination Date,
he shall provide written notice to the Company within three (3) business days of such eligibility.

 

Equity
or equity-based awards granted to Executive on or after the Effective Date, if any, shall be treated in accordance with, and governed
by and subject to, any applicable plan and award agreement under which they were granted.

Executive’s employment with the Company is terminated by reason of Executive’s death, this Agreement shall terminate
without further obligation to Executive’s legal representatives under this Agreement, other than for payment of the Accrued
Benefits and the amount of any Annual Bonus under Section 3(b) that relates to the year prior to termination and
that is unpaid as of the Termination Date (the “Unpaid Annual Bonus”). The accrued but unpaid Base Salary
shall be paid to Executive’s estate in a lump sum in cash within six (6) days after the Termination Date or by the next
regularly scheduled payday. Payment of any Unpaid Annual Bonus shall be made at such time as such bonus payments are normally

agreement under which they were granted. Executive, if deceased, and his beneficiaries, estate and legal representatives shall
not be entitled to any further payments or benefits whatsoever pursuant to this Agreement or otherwise.

 

(d)

Executive’s employment with the Company is terminated by reason of Executive’s Disability, this Agreement shall terminate,
and in full and complete satisfaction of its obligations under this Agreement, the Company shall pay Executive the Accrued Benefits,
and the amount of any Unpaid Annual Bonus. The accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash
within six (6) days after the Termination Date. Payment of any Unpaid Annual Bonus shall be made at such time as such bonus payments
are normally made, but in no event later than March 15 of the following year; provided that the amount of any such Unpaid Annual
Bonus shall be prorated based upon the number of days in such calendar years during which Executive was employed. Unreimbursed
business expenses shall be paid to Executive within the time period required by the Company’s business expense reimbursement
policy. Equity or equity-based awards granted to Executive, if any, shall be treated in accordance with, and governed by and subject

provided, however, that the Company may designate all or any portion of the 30-day notice period as non-working notice
and pay Executive the Base Salary through the end of such 30-day notice period. Upon such a termination by Executive, or upon
termination of Executive’s employment with the Company for Cause by the Company, this Agreement shall terminate. In full
and complete satisfaction of all obligations under this Agreement, the Company shall pay to Executive the Accrued Benefits. The
accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash within six (6) days after the Termination Date
or by the next regularly scheduled payday. Unreimbursed business expenses shall be paid to Executive within the time period required
by the Company’s business expense reimbursement policy. Executive shall have no entitlement to any Annual Bonus for the

limited to any bonus payments.

 

    	6 

    	 

    

 

(f)
No Duty to Mitigate Executive shall
not be required to mitigate the amount of any payment provided for in Section 4 of this Agreement by seeking other employment
or otherwise. No payment described in Section 4 of this Agreement shall be offset or reduced by the amount of any compensation
or benefits provided to Executive in any subsequent employment.

 

5.
Non-Renewal of Agreement. If the Company
or Executive elects not to renew this Agreement under the terms provided in Section 1, this Agreement shall terminate
effective on the last day of the then-current Term. Upon termination of this Agreement due to non-renewal by Executive, in full
satisfaction of its obligations under this Agreement, the Company shall provide Executive the Accrued Benefits. Executive shall
not be entitled to any further payments or benefits whatsoever pursuant to this Agreement or otherwise. Upon termination of this
Agreement due to non-renewal by the Company, in full satisfaction of its obligations under this Agreement, the Company shall provide
Executive the Accrued Benefits and, subject to Executive delivering to the Company an executed Release within the time period
set forth in such Release and Executive not revoking such Release, the Severance Payment.

 

6.
Release Agreement. Notwithstanding
any provision of this Agreement to the contrary, in order to receive the Severance Payment under Section 4(b)(2),
Executive must first execute, deliver to the Company, and not revoke a reasonable release and hold harmless agreement (on a form
provided by the Company) (“Release”), within the time period specified under the Release, whereby Executive
agrees in return for the Severance Payment, among other things that may be mutually agreed by the Parties, not to disparage the
Company, its employees, officers, directors and affiliates, and to release and waive any claim or cause of action that Executive
may have against the Company and any of its affiliates, including, without limitation, for unlawful discrimination or retaliation;
provided, however, such agreement shall not release any claim by Executive for any payment or benefit that is due under the express
terms of this Agreement at the time the time Executive executes the Release.

 

7.
Non-Competition, Non-Solicitation and Confidentiality. Executive
hereby acknowledges and agrees that during Executive’s employment with the Company, Executive has had and shall continue
to have access to some or all of the Company’s Confidential Information, as defined below.

 

(a)
Non-Competition During Employment. Executive
hereby agrees that, in consideration for the Company’s providing Executive with Confidential Information, during the Term,
he will not compete with the Company or any of its affiliates, including by engaging in the conception, design, development, production,
marketing, or servicing of any product or service that is substantially similar to the products or services which the Company
provides, and that he will not work for, in any capacity, assist, or become affiliated with as an owner, founder, shareholder,
partner, member, lender, advisor, director, consultant, contractor, agent, employee, affiliate or co-venturer, or otherwise act
in any capacity, either directly or indirectly, of, in or with respect to, any individual or business which offers or performs
services, or offers or provides products substantially similar to the services and products provided by the Company or any of
its affiliates; provided, however, Executive shall not be prevented from owning no more than 2% of any company whose stock
is publicly traded.

 

    	7 

    	 

    

 

(b)
Conflicts of Interest. Executive agrees
that during the Term, he will not engage, either directly or indirectly, in any activity (a “Conflict of Interest”)
that might adversely affect the Company, including ownership of a material investment in a competitor of the Company, ownership
of a material interest in any supplier, contractor, distributor, subcontractor, customer or other entity with which the Company
does business or acceptance of any material payment, service, loan, gift, trip, entertainment, or other favor from a supplier,
contractor, distributor, subcontractor, customer or other entity with which the Company does business, and that Executive will
promptly inform the CEO or the Eco-Stim Board of Directors as to each offer received by Executive to engage in any such activity.
As used in this Section 7(b), “materiality” shall be viewed from the perspective of Executive. Executive
further agrees to disclose to the Company any other facts of which Executive becomes aware which in Executive’s good faith
judgment could reasonably be expected to involve or give rise to a Conflict of Interest or potential Conflict of Interest.

 

(c)
Non-Competition After Termination from Employment. Executive
hereby agrees that, in order to protect the Company’s Confidential Information, it is necessary to enter into the following
restrictive covenant, which is ancillary to the enforceable promises between the Company and Executive otherwise contained in
this Agreement. Executive hereby agrees that Executive shall not at any time during the Restricted Period engage in any capacity,
whether as an owner, founder, shareholder, partner, member, lender, advisor, director, consultant, contractor, agent, employee,
affiliate or co-venturer, or otherwise, either directly or indirectly, in any commercial enterprise, a primary business of which
is to develop, manufacture, sell, lease, or otherwise provide any product, process, apparatus, service or development competitive
with or substantially similar to any product, process, apparatus, service, or development sold or provided by the Company or any
of its affiliates (“Competitive Products”) on which Executive worked or about which Executive learned
Confidential Information while employed by the Company anywhere within Texas, Oklahoma, Argentina, and/or any of the other markets
in which the Company or any of its affiliates has sold Competitive Products or formulated a plan to sell Competitive Products
into a market during the last twelve (12) months of Executive’s employ. It is understood that the geographical area set
forth in this covenant is divisible so that if this clause is invalid or unenforceable in an included geographic area, that area
is severable and the clause remains in effect for the remaining included geographic areas in which the clause is valid. For the
purpose of this Agreement, “Restricted Period” means a period of six (6) months after termination for
any reason whatsoever, whether by Executive or the Company, of Executive’s employment with the Company. The Restricted Period
shall commence at the time Executive’s employment with the Company terminates. The parties agree that this agreement of
non-competition is intended to be enforceable by the Company only to the extent that Texas law allows such a contractual limitation
and it shall be void beyond such permitted limitations.

(d)
Confidential Information. Executive
agrees that he will not, except as the Company may otherwise consent or direct in writing, reveal or disclose, sell, use, lecture
upon, publish or otherwise disclose to any third party any Confidential Information or proprietary information of the Company,
or authorize anyone else to do these things at any time either during or subsequent to his employment with the Company. This Section
7(d) shall continue in full force and effect after termination of Executive’s employment and after the termination
of this Agreement. Executive’s obligations under this Section 7(d) with respect to any specific Confidential
Information and proprietary information shall cease when that specific portion of the Confidential Information and proprietary
information becomes publicly known, in its entirety and without combining portions of such information obtained separately and
shall not apply to information that may be required by law or an order of any court, agency or proceeding to be disclosed (but
only for the purposes of and to the minimum extent required by such compelled disclosure, and provided that Executive promptly
notifies the Company of such requirement and provides the Company all reasonable assistance and cooperation in seeking to oppose
such requirement or obtain protective treatment). It is understood that such Confidential Information and proprietary information
of the Company include matters that Executive conceives or develops, as well as matters Executive learns from other employees
of the Company. “Confidential Information” is defined to include information: (1) disclosed to or known
by Executive as a consequence of or through his employment with the Company; (2) not generally known outside the Company; and
(3) that relates to any aspect of the Company or its business, finances, operation plans, budgets, research, or strategic development.
“Confidential Information” includes, but is not limited to, the Company’s trade secrets, proprietary
information, financial documents, long range plans, customer or supplier lists, marketing strategy, data bases, costing data,
computer software developed by the Company, investments made by the Company, and any information provided to the Company by a
third party under restrictions against disclosure or use by the Company or others. Nothing in this Agreement or otherwise shall
prohibit Executive from making a report to any governmental agency or entity if Executive has a reasonable belief that there has
been a potential violation of federal or state law or regulation or from making other disclosures that are protected under the
whistleblower provisions of any applicable federal or state law or regulation. No prior authorization to make any such reports
or disclosures is required and Executive is not required to notify the Company that Executive has made such reports or disclosures.
Executive, however, may not waive the Company’s attorney-client privilege. The Company and Executive acknowledge that pursuant
to 18 U.S.C § 1833(b)(1) a Company employee shall not be held criminally or civilly liable under any federal or state trade
secret law for the disclosure of a trade secret that (a) is made (i) in confidence to a federal, state, or local government official,
either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation
of law; or (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.
The Company and Executive further acknowledge that, pursuant to 18 U.S.C § 1833(b)(2) if an employee files a lawsuit for
retaliation by the Company for reporting a suspected violation of law, such employee may disclose the trade secret to his or her
attorney and use the trade secret information in the court proceeding, if the individual (A) files any document containing the
trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.

 

(e)
Work Product; Assignment; Patent and Copyright Registrations; Warranty. Executive
agrees that he has disclosed and will disclose promptly and fully to the Company all discoveries, developments, concepts, ideas,
know how, trade secrets, designs, inventions, improvements, processes, computer programs, algorithms, models, graphics, pictorial
representations, user interfaces, functional specifications, reports, spreadsheets, presentations, analyses, works of authorship,
and any improvements, enhancements, or documentation of or to the same, including any Confidential Information, whether or not
patentable, that he developed, made, worked on or conceived or reduced to practice, individually or jointly with others prior
to the date of this Agreement in any way related or pertaining to or connected with the present or anticipated business, development,
work or research of the Company, or that he develops, makes, works on, conceives or reduces to practice, individually or jointly
with others in the course of his work for the Company or with the use of the Company’s time, materials or facilities in
any way related or pertaining to or connected with the present or anticipated business, development, work or research of the Company
or which result from or are suggested by any work he may do for the Company and whether produced during normal business hours
or on personal time (collectively the “Work Product”). Work Product shall further include any such works of authorship,
inventions, discoveries, improvements, designs, processes, software or improvements thereto conceived, made, reduced to practice,
developed or perfected by Executive within six (6) months after termination of Executive’s employment with the Company.

Executive
shall make and maintain adequate and current written records and evidence of all Work Product, including drawings, work papers,
graphs, computer records and any other documents, which shall be considered Company property.

 

(1)
Work Made for Hire. Executive acknowledges
that all original works of authorship which are made by Executive (solely or jointly with others) within the scope of his employment
with the Company and which are protectable by copyright are “works made for hire,” pursuant to United States Copyright
Act (17 U.S.C., Section 101). If any of the works of authorship which are made by Executive (solely or jointly with others) within
the scope of his employment with the Company are held for any reason not to be “works made for hire” for the Company
or if ownership of all right, title and interest in and to such works has not vested exclusively and immediately in the Company
upon creation, Executive hereby irrevocably assigns, without further consideration, any and all right, title and interest in and
to such works to the Company, including any and all Intellectual Property Rights with respect thereto.

 

(2)
Assignment of Work Product. Executive
hereby agrees and confirms that all right, title and interest, including all Intellectual Property Rights (defined below), in
and to the existing Work Product has been irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned
at the time of creation, and/or is hereby irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned
to the Company, and Executive hereby agrees that all right, title and interest in future Work Product is and will be automatically
and irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned to the Company. Executive has not assigned
or otherwise granted any right in or to the Work Product to any third party and all Work Product is and shall be the exclusive
property of the Company. The Parties intended and intend that any and all copyright and other Intellectual Property Rights in
the Work Product, including without limitation any and all rights to distribute and reproduce such Work Product in any and all
media throughout the world, are the sole property of the Company.

 

“Intellectual
Property Rights” shall mean, on a world-wide basis, any and all now known or hereafter known tangible and intangible
(i) rights associated with works of authorship including, without limitation, copyrights, moral rights and mask-works, (ii) trademark
and trade name rights and similar rights, including all goodwill associated therewith, (iii) trade secret rights and database
rights, (iv) patent rights, all rights associated with designs, algorithms, computer programs, methods of doing business, ideas,
concepts, techniques, inventions (whether patentable or not), processes and other industrial property rights, (v) all other intellectual
and industrial property rights of every kind and nature and however designated, whether arising by operation of law, contract,
license or otherwise, and (vi) all registrations, initial applications, renewals, extensions, continuations, divisions or reissues
thereof now or hereafter existing, made, or in force, both foreign and domestic (including any rights in any of the foregoing).

(3)
Patent and Copyright Registrations.
The Company and its designees solely shall have the right to use and apply for common law and statutory protections of the Work
Product, including all patents, copyrights, mask work rights, and other intellectual property rights, in any and all countries
and jurisdictions. Furthermore, Executive agrees to assist the Company, or its designee, at the Company’s expense, in every
proper way to secure the Company’s rights in the Work Product and any copyrights, patents, mask work rights or other Intellectual
Property Rights relating thereto in any and all countries and jurisdictions, including the disclosure to the Company of all pertinent
information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other
instruments which the Company shall deem necessary in order to apply for, obtain, perfect and assign such rights in the name of
the Company. Executive further agrees that his obligation to execute or cause to be executed, when it is in his power to do so,
any such instrument or papers shall continue after the termination of Executive’s employment with the Company. If the Company
is unable, for any reason, to secure Executive’s signature to execute such instruments or papers relating to the Work Product,
then Executive hereby designates and appoints the Company and its duly authorized officers and agents as Executive’s agent
and attorney in fact, to act for and in Executive’s stead to record the Company’s ownership interest and to execute
and file any such instruments and papers relating to the Work Product and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent or copyright registrations thereon in the Company’s name with the same legal
force and effect as if executed by Executive. The foregoing agency shall apply to any applications or registrations, including
any divisions, continuations, renewals, reissues, and extensions and other instruments and papers, as applicable, now existing
or hereafter filed or issued. This agency is coupled with an interest and is irrevocable.

 

(4)
Unassigned Inventions. Executive recognizes
that the terms of this Agreement do not require him to assign to the Company any invention that was developed entirely on his
own time without using equipment, supplies, facilities, or trade secrets belonging to the Company and neither related to the actual
or anticipated business, research or development of the Company, nor resulting from work performed by Executive for the Company.

 

(f)
Non-Solicitation. To protect the Company’s
Confidential Information, and in the event of Executive’s termination of employment for any reason whatsoever, whether by
Executive or the Company, it is necessary to enter into the following restrictive covenant, which is ancillary to the enforceable
promises between the Company and Executive otherwise contained in this Agreement. Executive covenants and agrees that during Executive’s
employment and for a period of six (6) months from the date of termination of Executive’s employment for any reason whatsoever
(the “Non-Solicitation Period”), Executive will not, directly or indirectly, either individually or
as an owner, founder, shareholder, partner, member, lender, advisor, director, consultant, contractor, agent, employee, affiliate
or co-venturer, or otherwise act in any capacity, of, in or with respect to, any individual or business, except on behalf of the
Company, solicit business, or attempt to solicit business, or sell, lease, transfer, license, promote, or otherwise market products
or services competitive with products or services sold by the Company, to the Company’s clients, suppliers or customers,
or those individuals or entities with whom the Company did business, including those individuals or entities that the Company
actively solicited for business with Executive’s participation, during Executive’s employment. Executive further agrees
that during Executive’s employment and for the Non-Solicitation Period, Executive will not, either directly or indirectly,
or by acting in concert with others, solicit or influence any employee of the Company or any of its affiliates or independent
contractor engaged by the Company or any of its affiliates to end his or her employment or engagement with the Company or accept
employment or engagement with any entity in competition with the Company.

(g)
Return of Documents, Equipment, Etc. All
writings, records, and other documents and things comprising, containing, describing, discussing, explaining, or evidencing any
Confidential Information, and all equipment, components, parts, tools, and the like in Executive’s custody or possession
that have been obtained or prepared in the course of Executive’s employment with the Company shall be the exclusive property
of the Company, shall not be copied and/or removed from the premises of the Company, except in pursuit of the business of the
Company, and shall be delivered to the Company, without Executive retaining any copies, upon notification of the termination of
Executive’s employment or at any other time requested by the Company. The Company shall have the right to retain, access,
and inspect all property of Executive of any kind in the office, work area, and on the premises of the Company upon termination
of Executive’s employment and at any time during employment by the Company to ensure compliance with the terms of this Agreement.

 

(h)
Reaffirmation of Obligations. Upon
termination of Executive’s employment with the Company, Executive, if requested by Company, shall reaffirm in writing Executive’s
recognition of the importance of maintaining the confidentiality of the Company’s Confidential Information and proprietary
information, and reaffirm any other obligations set forth in this Agreement.

 

(i)
Prior Disclosure. Executive represents
and warrants that Executive has not used or disclosed any Confidential Information he may have obtained from the Company prior
to signing this Agreement, in any way inconsistent with the provisions of this Agreement.

 

(j)
No Previous Restrictive Agreements. Executive
represents that, except as disclosed in writing to the Company, Executive is not bound by the terms of any agreement with any
previous employer or other party to refrain from using or disclosing any trade secret or confidential or proprietary information
in the course of Executive’s employment by the Company or to refrain from competing, directly or indirectly, with the business
of such previous employer or any other party. Executive further represents that Executive’s performance of all the terms
of this Agreement and Executive’s work duties for the Company does not and will not breach any agreement to keep in confidence
proprietary information, knowledge or data acquired by Executive in confidence or in trust prior to Executive’s employment
with the Company, and Executive will not disclose to the Company or induce the Company to use any confidential or proprietary
information or material belonging to any previous employer or other party.

 

    	12 

    	 

    

 

(k)
Breach; Remedies and Representations. Executive
agrees that any breach of Sections 7(a) through (k) above will cause irreparable damage to the Company,
which cannot be remedied solely by money damages, and that in addition to any other remedies the Company may have, the Company
is entitled to obtain injunctive relief against Executive to prevent the breach or threatened breach of any of Executive’s
obligations thereunder. Nothing herein, however, shall be construed as limiting the Company’s right to pursue any other
available remedy at law or in equity, including recovery of damages and termination of this Agreement and/or any termination or
offset against any payments that may be due pursuant to this Agreement. Executive acknowledges that Executive is sophisticated
in business, that the restrictions and remedies set forth in this Section 7 do not create an undue hardship on Executive
and will not prevent Executive from earning a livelihood. Executive understands and agrees that the Company has a legitimate business
interest in protecting the Confidential Information provided to Executive during the course of Executive’s employment and
the goodwill associated with the client and other business relationships introduced to Executive and developed during Executive’s
employment with the Company. Executive further acknowledges that Executive has had a sufficient period of time within which to
review this Agreement with an attorney of Executive’s choice and Executive has done so to the extent he desired. Executive
and the Company agree that the restrictions and remedies contained in this Agreement are reasonable and necessary to protect the
Company’s legitimate business interests regardless of the reason for or circumstances giving rise to such termination and
that Executive and the Company intend that such restrictions and remedies shall be enforceable to the fullest extent permissible
by law.

 

(l)
Enforceability. The agreements contained
in this Section 7 are independent of the other agreements contained herein. Accordingly, failure of the Company
to comply with any of its obligations outside of this Section do not excuse Executive from complying with the agreements contained
herein.

 

(m)
Survivability. The agreements contained
in this Section 7 shall survive the termination of this Agreement for any reason.

 

(n)
Post-Employment Notice Obligations. During
the Term and continuing through the Restricted Period and the Non-Solicitation Period, Executive agrees to notify any person or
entity with whom Executive seeks or accepts employment or engagement, of Executive’s obligations under this Section
7. The Company similarly may notify any subsequent employer of Executive’s obligations under this Section
7 and Executive releases and holds the Company harmless in connection with such disclosure and the consequences thereof.
In addition, during the Restricted Period and the Non-Solicitation Period, Executive agrees to notify the Company, in writing,
not less than 3 business days before commencing employment or engagement with a third party and provide the following information:
(i) the name and address of the third party and (ii) Executive’s new title and general description of Executive’s
new job duties and responsibilities.

 

8.
Reformation. If a court concludes that
any time period or the geographic area specified in Sections 7(c) or (g) of this Agreement are unenforceable,
then the time period will be reduced by the number of months, or the geographic area will be reduced by the elimination of the
overbroad portion, or both, so that the restrictions may be enforced in the geographic area and for the time to the fullest extent
permitted by law.

 

    	13 

    	 

    

 

9.
Director and Officer Positions. Executive
agrees that, upon termination of employment, for any reason, Executive will immediately tender his resignation from any and all
Board or officer positions held with the Company and/or any of its direct or indirect parents or subsidiaries.

 

10.
Indemnification & D&O

 

(a)
Claims. The Company shall, to the maximum
extent not prohibited by law, indemnify Executive if Executive is made, or threatened to be made, a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in
the right of the Company to procure a judgment in its favor (collectively, a “Proceeding”), by reason
of the fact that Executive is or was an employee, director or officer of the Company or an affiliate, or is or was serving in
any capacity at the request of the Company for any other corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, against judgments, fines, penalties, excise taxes, amounts paid in settlement and costs, charges and expenses
(including attorneys’ fees and disbursements) paid or incurred in connection with any such Proceeding.

 

(b)
Non-Exclusivity. The right to indemnification
and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall not be deemed
exclusive of any other rights which Executive may now or hereafter have under any law, bylaw, constituent document, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action in Executive’s official capacity and as
to action in another capacity while holding such office.

 

(c)
Continuation of Rights. The right
to indemnification and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall
continue as to Executive after Executive has ceased to be a director, officer, or employee of the Company and shall inure to the
benefit of the heirs, executors and administrators of Executive’s estate, both with respect to proceedings that are threatened,
pending or completed at the date of such termination and with respect to proceedings that are threatened, pending or completed
after the date.

 

(d)
Enforcement. The right to indemnification
and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall be enforceable
by Executive in any court of competent jurisdiction. The burden of proving that such indemnification or reimbursement or advancement
of expenses is not appropriate shall be on the Company. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that such
indemnification or reimbursement or advancement of expenses is proper in the circumstances nor an actual determination by the
Company (including its board of directors, independent legal counsel, or its stockholders) that Executive is not entitled to such
indemnification or reimbursement or advancement of expenses shall constitute a defense to the action or create a presumption that
Executive is not so entitled. Executive shall also be indemnified for any expenses incurred in connection with successfully establishing
Executive’s right to such indemnification or reimbursement or advancement of expenses, in whole or in part, in any proceeding.

 

    	14 

    	 

    

 

(e)
Other Services. If Executive serves
(i) an affiliate of the Company, or (ii) any employee benefit plan of the Company or any corporation referred to in clause (i),
in any capacity, then Executive shall be deemed to be doing so at the request of the Company.

 

11.
Assignment. In entering into this Agreement,
the Company is relying on the unique personal services of Executive; services from another person will not be an acceptable substitute.
Executive may not assign this Agreement or any of the rights or obligations set forth in this Agreement without the written consent
of the Company; provided, however, Executive may assign any right to receive payment under this Agreement. Any attempted assignment
by Executive in violation of this Section 11 shall be void. This Agreement, and any rights and obligations hereunder,
shall be assigned by the Company to a successor by merger or a purchaser of substantially all of the assets of the Company.

 

12.
Tax Withholding. The payments and
benefits under this Agreement may be compensation and as such may be included in either Executive’s W-2 earnings statements
or 1099 statements. The Company may withhold from any amounts payable under this Agreement such federal, state or local taxes
as the Company shall determine are required to be withheld pursuant to any applicable law or regulation.

 

13.
Binding Agreement. Executive understands
that his obligations under this Agreement are binding upon Executive’s heirs, successors, personal representatives, and
legal representatives.

 

14.
Notices. All notices required or permitted
to be given pursuant to this Agreement shall be in writing and shall be delivered by hand
or sent by facsimile or sent, postage prepaid, by registered, certified or express mail or overnight courier service and
shall be deemed given when so delivered by hand or facsimile, or if mailed, three days after
mailing (one business day in the case of express mail or overnight courier service) to the parties at the following addresses
or facsimiles (or at such other address for a party as shall be specified by like notice):

    Chief Executive Officer

 

Executive
hereby agrees to provide the Company with prompt written notice of any change in Executive’s address for so long as this
Agreement remains in effect. Notices delivered by facsimile shall have the same legal effect as if such notice had been delivered
in person.

 

    	15 

    	 

    

 

15.
Waiver. No waiver by either Party to
this Agreement of any right to enforce any term or condition of this Agreement, or of any breach hereof, shall be deemed a waiver
of such right in the future or of any other right or remedy available under this Agreement.

 

16.
Entire Agreement. Except as may be
provided in any indemnification agreement between Executive and the Company and/or FracRock International, Inc. (“FracRock”),
the predecessor of the Company’s subsidiary, EcoStim International, Inc., and any plan and/or award agreement under which
Executive was granted any equity or equity-based award with the Company and its subsidiaries and their respective predecessors,
the terms of this Agreement are intended by the Parties to be the final expression of their agreement with respect to the employment
of Executive by the Company and supersede all prior understandings and agreements, whether written or oral, including, but not
limited to, the Prior Employment Agreement. In the event of a conflict between this Agreement and any such indemnification agreement,
it is intended that the agreement that grants Executive greater rights shall govern. Notwithstanding the foregoing, this Agreement
will not in any way affect any equity or equity-based awards that may be granted to Executive, which are governed by the applicable
plan and/or award agreements under which they were granted, except to the extent expressly provided for in such agreement or plan.
The Parties further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of
this Agreement.

 

17.
Modification of Agreement. This Agreement
may not be changed or modified or released or discharged or abandoned, in whole or in part, except by an instrument in writing
signed by Executive and an officer or other authorized executive of the Company.

 

18.
Governing Law. This Agreement shall
be governed by and construed in accordance with the laws of the State of Texas, without regard to the conflicts of laws principles
thereof.

 

19.
Jurisdiction and Venue. With respect
to any litigation regarding this Agreement, Executive and the Company agree to venue in the state or federal courts in Harris
County, Texas, and agrees to waive and does hereby waive any defenses and/or arguments based upon improper venue and/or lack of
personal jurisdiction. By entering into this Agreement, Executive and the Company agree to personal jurisdiction in the state
and federal courts in Harris County, Texas.

 

20.
Interpretation; Counterparts. No provision
of this Agreement is to be interpreted for or against any Party because that Party drafted such provision. Whenever the words
“include,” “includes” or “including” are used in this Agreement, they shall be deemed to be
followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,”
“herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement
as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The word “extent”
in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall
not mean simply “if.” The definitions contained in this Agreement are applicable to the singular as well as the plural
forms of such terms. All pronouns and any variations thereof refer to the masculine, feminine or neuter as the context may require.
Any agreement, instrument or law defined or referred to herein means such agreement, instrument or law as from time to time amended,
modified or supplemented, unless otherwise specifically indicated. This Agreement may be executed in two or more counterparts
(including by facsimile or portable document file (PDF) signatures), each of which shall be deemed an original and all such counterparts
shall constitute one and the same instrument.

21.
Compliance With Section 409A.

 

(a)
Delay in Payments. Notwithstanding
anything to the contrary in this Agreement, if upon the Termination Date, any stock of the Company is publicly traded on an established
securities market within the meaning of Code Section 409A, and in the opinion of reputable outside counsel engaged by the Company
and acceptable to Executive, Executive is a “specified employee” within the meaning of Code Section 409A and the deferral
of any amounts otherwise payable under this Agreement as a result of Executive’s termination of employment is necessary
in order to prevent any accelerated or additional tax to Executive under Code Section 409A, then the Company will defer the payment
of any such amounts hereunder until the earlier of: (i) the date that is six (6) months following the date of Executive’s
termination of employment with the Company, or (ii) the date of Executive’s death, at which time any such delayed
amounts will be paid to Executive in a single lump sum.

 

(b)
Section 409A. It is the intention of
the Parties that all payments and benefits under this Agreement (and any amendment hereto) shall be made and provided in a manner
that is either exempt from or intended to avoid taxation under Code Section 409A, to the extent applicable. Any ambiguity in this
Agreement (or any amendment hereto) shall be interpreted to comply with the above. Executive acknowledges that the Company has
made no representations as to the treatment of the compensation and benefits provided hereunder and Executive has been advised
to obtain his own tax advice. Each amount or benefit payable pursuant to this Agreement (and any amendment hereto) shall be deemed
a separate payment for purposes of Code Section 409A.

 

(c)
Reimbursement. To the extent that the
reimbursement of any expenses or the provision of any in-kind benefits pursuant to this Agreement is subject to Code Section 409A,
(A) the amount of such expenses eligible for reimbursement, or in-kind benefits to be provided hereunder during any one calendar
year shall not affect the amount of such expenses eligible for reimbursement or in-kind benefits to be provided hereunder in any
other calendar year; provided, however, that the foregoing shall not apply to any limit on the amount of any expenses
incurred by Executive that may be reimbursed or paid under the terms of the Company’s medical plan, if such limit is imposed
on all similarly situated participants in such plan; (B) all such expenses eligible for reimbursement hereunder shall be paid
to Executive no later than December 31st of the calendar year following the calendar year in which such expenses were incurred
or such earlier date as provided under the Company’s policies; and (C) Executive’s right to receive any such reimbursements
or in-kind benefits shall not be subject to liquidation or exchange for any other benefit.

 

(d)
Reformation. If the Company determines
that any compensation or benefits provided by this Agreement may result in the application of Code Section 409A, the Company shall,
in consultation with Executive, modify the Agreement in the least restrictive manner necessary in an effort to exclude such compensation
from the definition of “deferred compensation” within the meaning of such Code Section 409A or in an effort to comply
with the provisions of Code Section 409A, other applicable provision(s) of the Code and/or any rules, regulations or other regulatory
guidance issued under such statutory provisions, without any diminution in the value of the payments or benefits to Executive.
Notwithstanding the foregoing, the Company shall not be required to assume any increased economic burden.

 

(e)
Overall Compliance. In the event that
it is reasonably determined by the Company and Executive that, as a result of Code Section 409A, any of the payments that Executive
is entitled to under the terms of this Agreement or any nonqualified deferred compensation plan (as defined under Section 409A)
may not be made at the time contemplated by the terms hereof or thereof, as the case may be, without causing Executive to be subject
to an income tax penalty and interest, the Company will make such payment on the first day that would not result in Executive
incurring any tax liability under Section 409A.

 

(f)
Consultation with Tax Advisor. Executive
is hereby advised to consult immediately with his own tax advisor regarding the tax consequences of this Agreement, including
the consequences of Code Section 409A.

as follows:

 

AGREEMENT
TERMS:

 

1.
Term. The Company shall continue to

the other Party of his or its election not to renew this Agreement at least thirty (30) days prior to the last day of the then-current
Term. Executive’s employment hereunder shall be coterminous with the Term, and termination of Executive’s employment
and the Term shall be simultaneous.

 

    	 

    	 

    

 

2.
Duties as Executive of the Company. Subject
to this Agreement’s terms, Executive agrees to continue to serve the Company as its Chief Financial Officer, and to act
in the ordinary course of its business with all the powers and duties reasonably incident to the position(s) and such other responsibilities
or duties that may be from time to time assigned to Executive by the Board of Directors or the Company’s Chief Executive
Officer. Executive shall report to the Company’s Chief Executive Officer.

 

3.
Compensation and Related Matters.

 

(a)
Base Salary. Executive shall receive
an initial Base Salary (defined below) paid by the Company at the annual rate of $300,000 per year. Executive’s Base Salary
may be increased annually, effective on January 1 of each year beginning after the Effective Date, by an amount (if any) to be
determined by Eco-Stim, in its sole discretion. For purposes of this Agreement, “Base Salary” shall
mean Executive’s initial base salary or, the adjusted base salary then in effect at the time in question. The Base Salary
shall be paid, subject to all applicable withholdings and deductions, in accordance with the Company’s ordinary payroll
practices, as in effect from time to time.

 

(b)
Bonus Target. During each full calendar
year of the Term, Executive shall be eligible to receive an annual bonus in an amount, if any, to be determined by the Board of
Directors of Eco-Stim in its sole discretion, up to a maximum of one hundred percent (100%) of Executive’s
Base Salary (the “Annual Bonus”). The amount of the Annual Bonus awarded, if any, shall be based on
achieving certain goals related to Company performance and objectives, established and measured by the Board of Directors of Eco-Stim,
in its sole discretion. To receive any Annual Bonus for a calendar year, Executive must be in “active working status”
at the time such Annual Bonus is scheduled to be paid, except as otherwise provided in Section 4, below. For purposes of this
Agreement, “active working status” means that the Termination Date has not occurred for any reason and
Executive has not been given notice of termination of his employment for any reason, and Executive has not resigned his employment
or given notice of his resignation, for any reason.

 

(c)
Expenses. Executive shall be entitled
to receive prompt reimbursement for all reasonable business expenses incurred by him, in accordance with the policies and procedures
established by the Company from time to time, in performing services under this Agreement and during his employment with the Company,
provided that Executive properly accounts for the expenses in accordance with Company policies. The amount of expenses eligible
for reimbursement during a calendar year shall not affect the expenses eligible for reimbursement in any other calendar year.
Reimbursement of eligible expenses shall be made on or before the last day of the calendar month following the calendar month
in which the expenses were incurred, provided appropriate requests with supporting documentation are timely submitted in accordance
with, or as otherwise provided in, the Company’s business expense reimbursement policy.

shall be eligible to participate in such retirement and employee benefit plans and arrangements that may be offered to the Company’s
senior executives, subject to and on a basis consistent with the terms, conditions, and overall administration of such plans and

including any beneficiary, any rights under or with respect to any such plan or arrangement or to amend any such plan or arrangement,
and Executive and each other person, including any beneficiary, shall be entitled to look only to the express terms of any such
plan or arrangement for his or her rights thereunder. Nothing paid to Executive under any such plan or arrangement presently in
effect or made available in the future shall be deemed to be in lieu of the Base Salary and other benefits payable to Executive
pursuant to this Agreement.

 

    	2 

    	 

    

 

(e)
Vacation; Sick Leave; Holidays. Executive
shall be entitled to twenty (20) days of vacation and six (6) days of paid sick leave during each year of the Term, pro-rated
for partial years, exclusive of holidays. Executive shall insure that the scheduling of his vacation does not interfere with the
Company’s normal business operation. Vacation will accrue and may be forfeited as provided by the terms of the Company’s
policy governing vacation, as that policy is updated or revised from time to time in the Company’s sole discretion. For
purposes of this Section, weekends shall not count as Vacation days. Executive shall also be entitled to all paid holidays given
by the Company.

 

(f)
Proration. The Base Salary payable
to Executive hereunder in respect of any calendar year during which Executive is employed by the Company for less than the entire

that Executive has failed or refused substantially to perform; provided that Cause shall not include Executive’s failure
to so perform as a result of Executive’s incapacity due to his Disability;

provided, however, that Good Reason shall cease to exist on the thirtieth (30th) day following the later of (x) the occurrence
of the fact, event, condition or other circumstance constituting or giving rise to Good Reason or (y) Executive’s knowledge
thereof. During such thirty (30) day notice period, the Company shall have a cure right, and Executive’s termination for
Good Reason will be effective upon expiration of such cure period only if the fact, event, condition or other circumstance constituting
or giving rise to Good Reason is not cured within such period. Any such termination by Executive shall not be deemed a breach
of the Agreement. If the Company timely cures the fact, event, condition or other circumstance giving rise to Good Reason for
Executive’s resignation, the notice of termination shall become null and void.

 

(4)
“Termination Date” shall
mean the date Executive’s employment with the Company and this Agreement terminates or is terminated for any reason. To
the extent that any payments or benefits under this Agreement are considered nonqualified deferred compensation subject to Section
409A (“Code Section 409A”) of the Internal Revenue Code (the “Code”), to the
extent necessary to avoid additional taxes under Code Section 409A, such termination of employment will only be considered a termination
of employment to the extent it also constitutes a “separation from service” for purposes of Code Section 409A.

 

(b)
Termination Without Cause or for Good Reason: Benefits. In
the event the Company involuntarily terminates Executive’s employment with the Company without Cause or Executive terminates
his employment with the Company for Good Reason (in each case, a “Termination Event”), this Agreement
shall terminate, and, in full satisfaction of the Company’s obligations under this Agreement, Executive shall receive the
following:

 

    	4 

    	 

    

 

(1)
Payment of accrued but unpaid Base Salary
and unreimbursed business expenses through the Termination Date in accordance with Sections 3(a) and 3(c).
The accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash within six (6) days following the Termination
Date. Unreimbursed business expenses shall be paid to Executive within the time period required by the Company’s business
expense reimbursement policy. In addition, Executive and/or his eligible dependents shall be eligible to continue group health
benefits at his or their expense as provided by applicable law. The payments and benefits set forth in this Section 4(b)(1)
are referred to, collectively, as the “Accrued Benefits”; and

 

(2)
Subject to Executive delivering to the Company
an executed Release (as defined below in Section 6) within the time period set forth in such Release, and Executive
not revoking such Release, payment of an amount equal to the Base Salary payable for one year (the “Severance Payment”),
at the rate in effect immediately before the Termination Event, payable in a lump sum on the first payroll date on or immediately
after the sixtieth (60th) day following the Termination Date, provided that the Release has become effective on such date in accordance
with its terms.

 

(3)
Subject to Executive delivering to the Company
an executed Release within the time period set forth in such Release, and Executive not revoking such Release, full vesting of
all unvested restricted stock and stock options granted to Executive prior to the Effective Date and outstanding on the Termination
Date; and

 

(4)
Subject to Executive (x) delivering to the
Company an executed Release within the time period set forth in such Release, and Executive not revoking such Release, and (y)
timely electing medical benefit continuation pursuant to the COBRA, payment (or reimbursement of) the cost of medical benefit
continuation (on the same basis and at the same cost as such benefits are currently provided to executives of the Company) for
Executive and any covered dependents for up to eighteen (18) months or until Executive and/or his covered dependents are covered
by another company’s group health insurance, whichever is sooner; and provided, further, that if the Company determines
in good faith that its payment of such cost will result in the imposition of excise taxes or penalties on the Company and/or the
insurance carrier with respect to such medical benefits, then the Company shall not pay (or reimburse) such cost and the Company
shall provide an economically equivalent benefit or payment, to the extent that such benefit or payment is consistent with applicable
law and will not result in the imposition of such excise taxes or penalties. Executive covenants and agrees that if he becomes
eligible for coverage under another company’s group health insurance within eighteen (18) months of the Termination Date,
he shall provide written notice to the Company within three (3) business days of such eligibility.

 

Equity
or equity-based awards granted to Executive on or after the Effective Date, if any, shall be treated in accordance with, and governed
by and subject to, any applicable plan and award agreement under which they were granted.

 

    	5 

    	 

    

 

(c)
Termination In Event of Death: Benefits. If
Executive’s employment with the Company is terminated by reason of Executive’s death, this Agreement shall terminate
without further obligation to Executive’s legal representatives under this Agreement, other than for payment of the Accrued
Benefits and the amount of any Annual Bonus under Section 3(b) that relates to the year prior to termination and
that is unpaid as of the Termination Date (the “Unpaid Annual Bonus”). The accrued but unpaid Base Salary
shall be paid to Executive’s estate in a lump sum in cash within six (6) days after the Termination Date or by the next
regularly scheduled payday. Payment of any Unpaid Annual Bonus shall be made at such time as such bonus payments are normally
made, but in no event later than March 15 of the following year. Unreimbursed business expenses shall be paid to Executive’s
estate within the time period required by the Company’s business expense reimbursement policy. Equity or equity-based awards
granted to Executive, if any, shall be treated in accordance with, and governed by and subject to, any applicable plan and award
agreement under which they were granted. Executive, if deceased, and his beneficiaries, estate and legal representatives shall
not be entitled to any further payments or benefits whatsoever pursuant to this Agreement or otherwise.

 

(d)
Termination In Event of Disability: Benefits. If
Executive’s employment with the Company is terminated by reason of Executive’s Disability, this Agreement shall terminate,
and in full and complete satisfaction of its obligations under this Agreement, the Company shall pay Executive the Accrued Benefits,
and the amount of any Unpaid Annual Bonus. The accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash
within six (6) days after the Termination Date. Payment of any Unpaid Annual Bonus shall be made at such time as such bonus payments
are normally made, but in no event later than March 15 of the following year; provided that the amount of any such Unpaid Annual
Bonus shall be prorated based upon the number of days in such calendar years during which Executive was employed. Unreimbursed
business expenses shall be paid to Executive within the time period required by the Company’s business expense reimbursement
policy. Equity or equity-based awards granted to Executive, if any, shall be treated in accordance with, and governed by and subject
to, any applicable plan and award agreement under which they were granted. Executive, if Disabled, shall not be entitled to any
further payments or benefits whatsoever pursuant to this Agreement.

 

(e)
Voluntary Termination by Executive and Termination for Cause: Benefits. Executive
may terminate his employment with the Company by giving thirty (30) days’ prior written notice of his intent to so terminate;
provided, however, that the Company may designate all or any portion of the 30-day notice period as non-working notice
and pay Executive the Base Salary through the end of such 30-day notice period. Upon such a termination by Executive, or upon
termination of Executive’s employment with the Company for Cause by the Company, this Agreement shall terminate. In full
and complete satisfaction of all obligations under this Agreement, the Company shall pay to Executive the Accrued Benefits. The
accrued but unpaid Base Salary shall be paid to Executive in a lump sum in cash within six (6) days after the Termination Date
or by the next regularly scheduled payday. Unreimbursed business expenses shall be paid to Executive within the time period required
by the Company’s business expense reimbursement policy. Executive shall have no entitlement to any Annual Bonus for the
year in which the Termination Date occurs, any previously unpaid Annual Bonus, or otherwise. After the Termination Date, Executive
shall not be entitled to any further payments or benefits whatsoever pursuant to this Agreement or otherwise, including, but not
limited to any bonus payments.

 

    	6 

    	 

    

 

(f)
No Duty to Mitigate Executive shall
not be required to mitigate the amount of any payment provided for in Section 4 of this Agreement by seeking other employment
or otherwise. No payment described in Section 4 of this Agreement shall be offset or reduced by the amount of any compensation
or benefits provided to Executive in any subsequent employment.

 

5.
Non-Renewal of Agreement. If the Company
or Executive elects not to renew this Agreement under the terms provided in Section 1, this Agreement shall terminate
effective on the last day of the then-current Term. Upon termination of this Agreement due to non-renewal by Executive, in full
satisfaction of its obligations under this Agreement, the Company shall provide Executive the Accrued Benefits. Executive shall
not be entitled to any further payments or benefits whatsoever pursuant to this Agreement or otherwise. Upon termination of this
Agreement due to non-renewal by the Company, in full satisfaction of its obligations under this Agreement, the Company shall provide
Executive the Accrued Benefits and, subject to Executive delivering to the Company an executed Release within the time period
set forth in such Release and Executive not revoking such Release, the Severance Payment.

 

6.
Release Agreement. Notwithstanding
any provision of this Agreement to the contrary, in order to receive the Severance Payment under Section 4(b)(2),
Executive must first execute, deliver to the Company, and not revoke a reasonable release and hold harmless agreement (on a form
provided by the Company) (“Release”), within the time period specified under the Release, whereby Executive
agrees in return for the Severance Payment, among other things that may be mutually agreed by the Parties, not to disparage the
Company, its employees, officers, directors and affiliates, and to release and waive any claim or cause of action that Executive
may have against the Company and any of its affiliates, including, without limitation, for unlawful discrimination or retaliation;
provided, however, such agreement shall not release any claim by Executive for any payment or benefit that is due under the express
terms of this Agreement at the time the time Executive executes the Release.

 

7.
Non-Competition, Non-Solicitation and Confidentiality. Executive
hereby acknowledges and agrees that during Executive’s employment with the Company, Executive has had and shall continue
to have access to some or all of the Company’s Confidential Information, as defined below.

 

(a)
Non-Competition During Employment. Executive
hereby agrees that, in consideration for the Company’s providing Executive with Confidential Information, during the Term,
he will not compete with the Company or any of its affiliates, including by engaging in the conception, design, development, production,
marketing, or servicing of any product or service that is substantially similar to the products or services which the Company
provides, and that he will not work for, in any capacity, assist, or become affiliated with as an owner, founder, shareholder,
partner, member, lender, advisor, director, consultant, contractor, agent, employee, affiliate or co-venturer, or otherwise act
in any capacity, either directly or indirectly, of, in or with respect to, any individual or business which offers or performs
services, or offers or provides products substantially similar to the services and products provided by the Company or any of
its affiliates; provided, however, Executive shall not be prevented from owning no more than 2% of any company whose stock
is publicly traded.

 

    	7 

    	 

    

 

(b)
Conflicts of Interest. Executive agrees
that during the Term, he will not engage, either directly or indirectly, in any activity (a “Conflict of Interest”)
that might adversely affect the Company, including ownership of a material investment in a competitor of the Company, ownership
of a material interest in any supplier, contractor, distributor, subcontractor, customer or other entity with which the Company
does business or acceptance of any material payment, service, loan, gift, trip, entertainment, or other favor from a supplier,
contractor, distributor, subcontractor, customer or other entity with which the Company does business, and that Executive will
promptly inform the CEO or the Eco-Stim Board of Directors as to each offer received by Executive to engage in any such activity.
As used in this Section 7(b), “materiality” shall be viewed from the perspective of Executive. Executive
further agrees to disclose to the Company any other facts of which Executive becomes aware which in Executive’s good faith
judgment could reasonably be expected to involve or give rise to a Conflict of Interest or potential Conflict of Interest.

 

(c)
Non-Competition After Termination from Employment. Executive
hereby agrees that, in order to protect the Company’s Confidential Information, it is necessary to enter into the following
restrictive covenant, which is ancillary to the enforceable promises between the Company and Executive otherwise contained in
this Agreement. Executive hereby agrees that Executive shall not at any time during the Restricted Period engage in any capacity,
whether as an owner, founder, shareholder, partner, member, lender, advisor, director, consultant, contractor, agent, employee,
affiliate or co-venturer, or otherwise, either directly or indirectly, in any commercial enterprise, a primary business of which
is to develop, manufacture, sell, lease, or otherwise provide any product, process, apparatus, service or development competitive
with or substantially similar to any product, process, apparatus, service, or development sold or provided by the Company or any
of its affiliates (“Competitive Products”) on which Executive worked or about which Executive learned
Confidential Information while employed by the Company anywhere within Texas, Oklahoma, Argentina, and/or any of the other markets
in which the Company or any of its affiliates has sold Competitive Products or formulated a plan to sell Competitive Products
into a market during the last twelve (12) months of Executive’s employ. It is understood that the geographical area set
forth in this covenant is divisible so that if this clause is invalid or unenforceable in an included geographic area, that area
is severable and the clause remains in effect for the remaining included geographic areas in which the clause is valid. For the
purpose of this Agreement, “Restricted Period” means a period of six (6) months after termination for
any reason whatsoever, whether by Executive or the Company, of Executive’s employment with the Company. The Restricted Period
shall commence at the time Executive’s employment with the Company terminates. The parties agree that this agreement of
non-competition is intended to be enforceable by the Company only to the extent that Texas law allows such a contractual limitation
and it shall be void beyond such permitted limitations.

 

    	8 

    	 

    

 

(d)
Confidential Information. Executive
agrees that he will not, except as the Company may otherwise consent or direct in writing, reveal or disclose, sell, use, lecture
upon, publish or otherwise disclose to any third party any Confidential Information or proprietary information of the Company,
or authorize anyone else to do these things at any time either during or subsequent to his employment with the Company. This Section
7(d) shall continue in full force and effect after termination of Executive’s employment and after the termination
of this Agreement. Executive’s obligations under this Section 7(d) with respect to any specific Confidential
Information and proprietary information shall cease when that specific portion of the Confidential Information and proprietary
information becomes publicly known, in its entirety and without combining portions of such information obtained separately and
shall not apply to information that may be required by law or an order of any court, agency or proceeding to be disclosed (but
only for the purposes of and to the minimum extent required by such compelled disclosure, and provided that Executive promptly
notifies the Company of such requirement and provides the Company all reasonable assistance and cooperation in seeking to oppose
such requirement or obtain protective treatment). It is understood that such Confidential Information and proprietary information
of the Company include matters that Executive conceives or develops, as well as matters Executive learns from other employees
of the Company. “Confidential Information” is defined to include information: (1) disclosed to or known
by Executive as a consequence of or through his employment with the Company; (2) not generally known outside the Company; and
(3) that relates to any aspect of the Company or its business, finances, operation plans, budgets, research, or strategic development.
“Confidential Information” includes, but is not limited to, the Company’s trade secrets, proprietary
information, financial documents, long range plans, customer or supplier lists, marketing strategy, data bases, costing data,
computer software developed by the Company, investments made by the Company, and any information provided to the Company by a
third party under restrictions against disclosure or use by the Company or others. Nothing in this Agreement or otherwise shall
prohibit Executive from making a report to any governmental agency or entity if Executive has a reasonable belief that there has
been a potential violation of federal or state law or regulation or from making other disclosures that are protected under the
whistleblower provisions of any applicable federal or state law or regulation. No prior authorization to make any such reports
or disclosures is required and Executive is not required to notify the Company that Executive has made such reports or disclosures.
Executive, however, may not waive the Company’s attorney-client privilege. The Company and Executive acknowledge that pursuant
to 18 U.S.C § 1833(b)(1) a Company employee shall not be held criminally or civilly liable under any federal or state trade
secret law for the disclosure of a trade secret that (a) is made (i) in confidence to a federal, state, or local government official,
either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation
of law; or (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.
The Company and Executive further acknowledge that, pursuant to 18 U.S.C § 1833(b)(2) if an employee files a lawsuit for
retaliation by the Company for reporting a suspected violation of law, such employee may disclose the trade secret to his or her
attorney and use the trade secret information in the court proceeding, if the individual (A) files any document containing the
trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.

 

(e)
Work Product; Assignment; Patent and Copyright Registrations; Warranty. Executive
agrees that he has disclosed and will disclose promptly and fully to the Company all discoveries, developments, concepts, ideas,
know how, trade secrets, designs, inventions, improvements, processes, computer programs, algorithms, models, graphics, pictorial
representations, user interfaces, functional specifications, reports, spreadsheets, presentations, analyses, works of authorship,
and any improvements, enhancements, or documentation of or to the same, including any Confidential Information, whether or not
patentable, that he developed, made, worked on or conceived or reduced to practice, individually or jointly with others prior
to the date of this Agreement in any way related or pertaining to or connected with the present or anticipated business, development,
work or research of the Company, or that he develops, makes, works on, conceives or reduces to practice, individually or jointly
with others in the course of his work for the Company or with the use of the Company’s time, materials or facilities in
any way related or pertaining to or connected with the present or anticipated business, development, work or research of the Company
or which result from or are suggested by any work he may do for the Company and whether produced during normal business hours
or on personal time (collectively the “Work Product”). Work Product shall further include any such works of authorship,
inventions, discoveries, improvements, designs, processes, software or improvements thereto conceived, made, reduced to practice,
developed or perfected by Executive within six (6) months after termination of Executive’s employment with the Company.

 

    	9 

    	 

    

 

Executive
shall make and maintain adequate and current written records and evidence of all Work Product, including drawings, work papers,
graphs, computer records and any other documents, which shall be considered Company property.

 

(1)
Work Made for Hire. Executive acknowledges
that all original works of authorship which are made by Executive (solely or jointly with others) within the scope of his employment
with the Company and which are protectable by copyright are “works made for hire,” pursuant to United States Copyright
Act (17 U.S.C., Section 101). If any of the works of authorship which are made by Executive (solely or jointly with others) within
the scope of his employment with the Company are held for any reason not to be “works made for hire” for the Company
or if ownership of all right, title and interest in and to such works has not vested exclusively and immediately in the Company
upon creation, Executive hereby irrevocably assigns, without further consideration, any and all right, title and interest in and
to such works to the Company, including any and all Intellectual Property Rights with respect thereto.

 

(2)
Assignment of Work Product. Executive
hereby agrees and confirms that all right, title and interest, including all Intellectual Property Rights (defined below), in
and to the existing Work Product has been irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned
at the time of creation, and/or is hereby irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned
to the Company, and Executive hereby agrees that all right, title and interest in future Work Product is and will be automatically
and irrevocably (subject to the provisions of 17 U.S.C. §203, if applicable) assigned to the Company. Executive has not assigned
or otherwise granted any right in or to the Work Product to any third party and all Work Product is and shall be the exclusive
property of the Company. The Parties intended and intend that any and all copyright and other Intellectual Property Rights in
the Work Product, including without limitation any and all rights to distribute and reproduce such Work Product in any and all
media throughout the world, are the sole property of the Company.

 

“Intellectual
Property Rights” shall mean, on a world-wide basis, any and all now known or hereafter known tangible and intangible
(i) rights associated with works of authorship including, without limitation, copyrights, moral rights and mask-works, (ii) trademark
and trade name rights and similar rights, including all goodwill associated therewith, (iii) trade secret rights and database
rights, (iv) patent rights, all rights associated with designs, algorithms, computer programs, methods of doing business, ideas,
concepts, techniques, inventions (whether patentable or not), processes and other industrial property rights, (v) all other intellectual
and industrial property rights of every kind and nature and however designated, whether arising by operation of law, contract,
license or otherwise, and (vi) all registrations, initial applications, renewals, extensions, continuations, divisions or reissues
thereof now or hereafter existing, made, or in force, both foreign and domestic (including any rights in any of the foregoing).

 

    	10 

    	 

    

 

(3)
Patent and Copyright Registrations.
The Company and its designees solely shall have the right to use and apply for common law and statutory protections of the Work
Product, including all patents, copyrights, mask work rights, and other intellectual property rights, in any and all countries
and jurisdictions. Furthermore, Executive agrees to assist the Company, or its designee, at the Company’s expense, in every
proper way to secure the Company’s rights in the Work Product and any copyrights, patents, mask work rights or other Intellectual
Property Rights relating thereto in any and all countries and jurisdictions, including the disclosure to the Company of all pertinent
information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other
instruments which the Company shall deem necessary in order to apply for, obtain, perfect and assign such rights in the name of
the Company. Executive further agrees that his obligation to execute or cause to be executed, when it is in his power to do so,
any such instrument or papers shall continue after the termination of Executive’s employment with the Company. If the Company
is unable, for any reason, to secure Executive’s signature to execute such instruments or papers relating to the Work Product,
then Executive hereby designates and appoints the Company and its duly authorized officers and agents as Executive’s agent
and attorney in fact, to act for and in Executive’s stead to record the Company’s ownership interest and to execute
and file any such instruments and papers relating to the Work Product and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent or copyright registrations thereon in the Company’s name with the same legal
force and effect as if executed by Executive. The foregoing agency shall apply to any applications or registrations, including
any divisions, continuations, renewals, reissues, and extensions and other instruments and papers, as applicable, now existing
or hereafter filed or issued. This agency is coupled with an interest and is irrevocable.

 

(4)
Unassigned Inventions. Executive recognizes
that the terms of this Agreement do not require him to assign to the Company any invention that was developed entirely on his
own time without using equipment, supplies, facilities, or trade secrets belonging to the Company and neither related to the actual
or anticipated business, research or development of the Company, nor resulting from work performed by Executive for the Company.

 

(f)
Non-Solicitation. To protect the Company’s
Confidential Information, and in the event of Executive’s termination of employment for any reason whatsoever, whether by
Executive or the Company, it is necessary to enter into the following restrictive covenant, which is ancillary to the enforceable
promises between the Company and Executive otherwise contained in this Agreement. Executive covenants and agrees that during Executive’s
employment and for a period of six (6) months from the date of termination of Executive’s employment for any reason whatsoever
(the “Non-Solicitation Period”), Executive will not, directly or indirectly, either individually or
as an owner, founder, shareholder, partner, member, lender, advisor, director, consultant, contractor, agent, employee, affiliate
or co-venturer, or otherwise act in any capacity, of, in or with respect to, any individual or business, except on behalf of the
Company, solicit business, or attempt to solicit business, or sell, lease, transfer, license, promote, or otherwise market products
or services competitive with products or services sold by the Company, to the Company’s clients, suppliers or customers,
or those individuals or entities with whom the Company did business, including those individuals or entities that the Company
actively solicited for business with Executive’s participation, during Executive’s employment. Executive further agrees
that during Executive’s employment and for the Non-Solicitation Period, Executive will not, either directly or indirectly,
or by acting in concert with others, solicit or influence any employee of the Company or any of its affiliates or independent
contractor engaged by the Company or any of its affiliates to end his or her employment or engagement with the Company or accept
employment or engagement with any entity in competition with the Company.

 

    	11 

    	 

    

 

(g)
Return of Documents, Equipment, Etc. All
writings, records, and other documents and things comprising, containing, describing, discussing, explaining, or evidencing any
Confidential Information, and all equipment, components, parts, tools, and the like in Executive’s custody or possession
that have been obtained or prepared in the course of Executive’s employment with the Company shall be the exclusive property
of the Company, shall not be copied and/or removed from the premises of the Company, except in pursuit of the business of the
Company, and shall be delivered to the Company, without Executive retaining any copies, upon notification of the termination of
Executive’s employment or at any other time requested by the Company. The Company shall have the right to retain, access,
and inspect all property of Executive of any kind in the office, work area, and on the premises of the Company upon termination
of Executive’s employment and at any time during employment by the Company to ensure compliance with the terms of this Agreement.

 

(h)
Reaffirmation of Obligations. Upon
termination of Executive’s employment with the Company, Executive, if requested by Company, shall reaffirm in writing Executive’s
recognition of the importance of maintaining the confidentiality of the Company’s Confidential Information and proprietary
information, and reaffirm any other obligations set forth in this Agreement.

 

(i)
Prior Disclosure. Executive represents
and warrants that Executive has not used or disclosed any Confidential Information he may have obtained from the Company prior
to signing this Agreement, in any way inconsistent with the provisions of this Agreement.

 

(j)
No Previous Restrictive Agreements. Executive
represents that, except as disclosed in writing to the Company, Executive is not bound by the terms of any agreement with any
previous employer or other party to refrain from using or disclosing any trade secret or confidential or proprietary information
in the course of Executive’s employment by the Company or to refrain from competing, directly or indirectly, with the business
of such previous employer or any other party. Executive further represents that Executive’s performance of all the terms
of this Agreement and Executive’s work duties for the Company does not and will not breach any agreement to keep in confidence
proprietary information, knowledge or data acquired by Executive in confidence or in trust prior to Executive’s employment
with the Company, and Executive will not disclose to the Company or induce the Company to use any confidential or proprietary
information or material belonging to any previous employer or other party.

 

    	12 

    	 

    

 

(k)
Breach; Remedies and Representations. Executive
agrees that any breach of Sections 7(a) through (k) above will cause irreparable damage to the Company,
which cannot be remedied solely by money damages, and that in addition to any other remedies the Company may have, the Company
is entitled to obtain injunctive relief against Executive to prevent the breach or threatened breach of any of Executive’s
obligations thereunder. Nothing herein, however, shall be construed as limiting the Company’s right to pursue any other
available remedy at law or in equity, including recovery of damages and termination of this Agreement and/or any termination or
offset against any payments that may be due pursuant to this Agreement. Executive acknowledges that Executive is sophisticated
in business, that the restrictions and remedies set forth in this Section 7 do not create an undue hardship on Executive
and will not prevent Executive from earning a livelihood. Executive understands and agrees that the Company has a legitimate business
interest in protecting the Confidential Information provided to Executive during the course of Executive’s employment and
the goodwill associated with the client and other business relationships introduced to Executive and developed during Executive’s
employment with the Company. Executive further acknowledges that Executive has had a sufficient period of time within which to
review this Agreement with an attorney of Executive’s choice and Executive has done so to the extent he desired. Executive
and the Company agree that the restrictions and remedies contained in this Agreement are reasonable and necessary to protect the
Company’s legitimate business interests regardless of the reason for or circumstances giving rise to such termination and
that Executive and the Company intend that such restrictions and remedies shall be enforceable to the fullest extent permissible
by law.

 

(l)
Enforceability. The agreements contained
in this Section 7 are independent of the other agreements contained herein. Accordingly, failure of the Company
to comply with any of its obligations outside of this Section do not excuse Executive from complying with the agreements contained
herein.

 

(m)
Survivability. The agreements contained
in this Section 7 shall survive the termination of this Agreement for any reason.

 

(n)
Post-Employment Notice Obligations. During
the Term and continuing through the Restricted Period and the Non-Solicitation Period, Executive agrees to notify any person or
entity with whom Executive seeks or accepts employment or engagement, of Executive’s obligations under this Section
7. The Company similarly may notify any subsequent employer of Executive’s obligations under this Section
7 and Executive releases and holds the Company harmless in connection with such disclosure and the consequences thereof.
In addition, during the Restricted Period and the Non-Solicitation Period, Executive agrees to notify the Company, in writing,
not less than 3 business days before commencing employment or engagement with a third party and provide the following information:
(i) the name and address of the third party and (ii) Executive’s new title and general description of Executive’s
new job duties and responsibilities.

 

8.
Reformation. If a court concludes that
any time period or the geographic area specified in Sections 7(c) or (g) of this Agreement are unenforceable,
then the time period will be reduced by the number of months, or the geographic area will be reduced by the elimination of the
overbroad portion, or both, so that the restrictions may be enforced in the geographic area and for the time to the fullest extent
permitted by law.

 

    	13 

    	 

    

 

9.
Director and Officer Positions. Executive
agrees that, upon termination of employment, for any reason, Executive will immediately tender his resignation from any and all
Board or officer positions held with the Company and/or any of its direct or indirect parents or subsidiaries.

 

10.
Indemnification & D&O

 

(a)
Claims. The Company shall, to the maximum
extent not prohibited by law, indemnify Executive if Executive is made, or threatened to be made, a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, including an action by or in
the right of the Company to procure a judgment in its favor (collectively, a “Proceeding”), by reason
of the fact that Executive is or was an employee, director or officer of the Company or an affiliate, or is or was serving in
any capacity at the request of the Company for any other corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, against judgments, fines, penalties, excise taxes, amounts paid in settlement and costs, charges and expenses
(including attorneys’ fees and disbursements) paid or incurred in connection with any such Proceeding.

 

(b)
Non-Exclusivity. The right to indemnification
and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall not be deemed
exclusive of any other rights which Executive may now or hereafter have under any law, bylaw, constituent document, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action in Executive’s official capacity and as
to action in another capacity while holding such office.

 

(c)
Continuation of Rights. The right
to indemnification and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall
continue as to Executive after Executive has ceased to be a director, officer, or employee of the Company and shall inure to the
benefit of the heirs, executors and administrators of Executive’s estate, both with respect to proceedings that are threatened,
pending or completed at the date of such termination and with respect to proceedings that are threatened, pending or completed
after the date.

 

(d)
Enforcement. The right to indemnification
and reimbursement or advancement of expenses provided by, or granted pursuant to, this Section 10 shall be enforceable
by Executive in any court of competent jurisdiction. The burden of proving that such indemnification or reimbursement or advancement
of expenses is not appropriate shall be on the Company. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that such
indemnification or reimbursement or advancement of expenses is proper in the circumstances nor an actual determination by the
Company (including its board of directors, independent legal counsel, or its stockholders) that Executive is not entitled to such
indemnification or reimbursement or advancement of expenses shall constitute a defense to the action or create a presumption that
Executive is not so entitled. Executive shall also be indemnified for any expenses incurred in connection with successfully establishing
Executive’s right to such indemnification or reimbursement or advancement of expenses, in whole or in part, in any proceeding.

(e)
Other Services. If Executive serves
(i) an affiliate of the Company, or (ii) any employee benefit plan of the Company or any corporation referred to in clause (i),
in any capacity, then Executive shall be deemed to be doing so at the request of the Company.

 

11.
Assignment. In entering into this Agreement,
the Company is relying on the unique personal services of Executive; services from another person will not be an acceptable substitute.
Executive may not assign this Agreement or any of the rights or obligations set forth in this Agreement without the written consent
of the Company; provided, however, Executive may assign any right to receive payment under this Agreement. Any attempted assignment
by Executive in violation of this Section 11 shall be void. This Agreement, and any rights and obligations hereunder,
shall be assigned by the Company to a successor by merger or a purchaser of substantially all of the assets of the Company.

 

12.
Tax Withholding. The payments and
benefits under this Agreement may be compensation and as such may be included in either Executive’s W-2 earnings statements
or 1099 statements. The Company may withhold from any amounts payable under this Agreement such federal, state or local taxes
as the Company shall determine are required to be withheld pursuant to any applicable law or regulation.

 

13.
Binding Agreement. Executive understands
that his obligations under this Agreement are binding upon Executive’s heirs, successors, personal representatives, and
legal representatives.

 

14.
Notices. All notices required or permitted
to be given pursuant to this Agreement shall be in writing and shall be delivered by hand
or sent by facsimile or sent, postage prepaid, by registered, certified or express mail or overnight courier service and

    	15 

    	 

    

 

15.
Waiver. No waiver by either Party to
this Agreement of any right to enforce any term or condition of this Agreement, or of any breach hereof, shall be deemed a waiver
of such right in the future or of any other right or remedy available under this Agreement.

 

16.
Entire Agreement. Except as may be
provided in any indemnification agreement between Executive and the Company and/or FracRock International, Inc. (“FracRock”),
the predecessor of the Company’s subsidiary, EcoStim International, Inc., and any plan and/or award agreement under which
Executive was granted any equity or equity-based award with the Company and its subsidiaries and their respective predecessors,
the terms of this Agreement are intended by the Parties to be the final expression of their agreement with respect to the employment
of Executive by the Company and supersede all prior understandings and agreements, whether written or oral, including, but not
limited to, the Prior Employment Agreement. In the event of a conflict between this Agreement and any such indemnification agreement,
it is intended that the agreement that grants Executive greater rights shall govern. Notwithstanding the foregoing, this Agreement
will not in any way affect any equity or equity-based awards that may be granted to Executive, which are governed by the applicable
plan and/or award agreements under which they were granted, except to the extent expressly provided for in such agreement or plan.
The Parties further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of
this Agreement.

 

17.
Modification of Agreement. This Agreement
may not be changed or modified or released or discharged or abandoned, in whole or in part, except by an instrument in writing
signed by Executive and an officer or other authorized executive of the Company.

 

18.
Governing Law. This Agreement shall
be governed by and construed in accordance with the laws of the State of Texas, without regard to the conflicts of laws principles
thereof.

 

19.
Jurisdiction and Venue. With respect
to any litigation regarding this Agreement, Executive and the Company agree to venue in the state or federal courts in Harris
County, Texas, and agrees to waive and does hereby waive any defenses and/or arguments based upon improper venue and/or lack of
personal jurisdiction. By entering into this Agreement, Executive and the Company agree to personal jurisdiction in the state
and federal courts in Harris County, Texas.

 

20.
Interpretation; Counterparts. No provision
of this Agreement is to be interpreted for or against any Party because that Party drafted such provision. Whenever the words
“include,” “includes” or “including” are used in this Agreement, they shall be deemed to be
followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,”
“herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement
as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The word “extent”
in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall
not mean simply “if.” The definitions contained in this Agreement are applicable to the singular as well as the plural
forms of such terms. All pronouns and any variations thereof refer to the masculine, feminine or neuter as the context may require.
Any agreement, instrument or law defined or referred to herein means such agreement, instrument or law as from time to time amended,
modified or supplemented, unless otherwise specifically indicated. This Agreement may be executed in two or more counterparts
(including by facsimile or portable document file (PDF) signatures), each of which shall be deemed an original and all such counterparts
shall constitute one and the same instrument.

21.
Compliance With Section 409A.

 

(a)
Delay in Payments. Notwithstanding
anything to the contrary in this Agreement, if upon the Termination Date, any stock of the Company is publicly traded on an established
securities market within the meaning of Code Section 409A, and in the opinion of reputable outside counsel engaged by the Company
and acceptable to Executive, Executive is a “specified employee” within the meaning of Code Section 409A and the deferral
of any amounts otherwise payable under this Agreement as a result of Executive’s termination of employment is necessary
in order to prevent any accelerated or additional tax to Executive under Code Section 409A, then the Company will defer the payment
of any such amounts hereunder until the earlier of: (i) the date that is six (6) months following the date of Executive’s
termination of employment with the Company, or (ii) the date of Executive’s death, at which time any such delayed
amounts will be paid to Executive in a single lump sum.

 

(b)
Section 409A. It is the intention of
the Parties that all payments and benefits under this Agreement (and any amendment hereto) shall be made and provided in a manner
that is either exempt from or intended to avoid taxation under Code Section 409A, to the extent applicable. Any ambiguity in this
Agreement (or any amendment hereto) shall be interpreted to comply with the above. Executive acknowledges that the Company has
made no representations as to the treatment of the compensation and benefits provided hereunder and Executive has been advised
to obtain his own tax advice. Each amount or benefit payable pursuant to this Agreement (and any amendment hereto) shall be deemed
a separate payment for purposes of Code Section 409A.

 

(c)
Reimbursement. To the extent that the
reimbursement of any expenses or the provision of any in-kind benefits pursuant to this Agreement is subject to Code Section 409A,
(A) the amount of such expenses eligible for reimbursement, or in-kind benefits to be provided hereunder during any one calendar
year shall not affect the amount of such expenses eligible for reimbursement or in-kind benefits to be provided hereunder in any
other calendar year; provided, however, that the foregoing shall not apply to any limit on the amount of any expenses
incurred by Executive that may be reimbursed or paid under the terms of the Company’s medical plan, if such limit is imposed
on all similarly situated participants in such plan; (B) all such expenses eligible for reimbursement hereunder shall be paid
to Executive no later than December 31st of the calendar year following the calendar year in which such expenses were incurred
or such earlier date as provided under the Company’s policies; and (C) Executive’s right to receive any such reimbursements
or in-kind benefits shall not be subject to liquidation or exchange for any other benefit.

 

(d)
Reformation. If the Company determines
that any compensation or benefits provided by this Agreement may result in the application of Code Section 409A, the Company shall,
in consultation with Executive, modify the Agreement in the least restrictive manner necessary in an effort to exclude such compensation
from the definition of “deferred compensation” within the meaning of such Code Section 409A or in an effort to comply
with the provisions of Code Section 409A, other applicable provision(s) of the Code and/or any rules, regulations or other regulatory
guidance issued under such statutory provisions, without any diminution in the value of the payments or benefits to Executive.
Notwithstanding the foregoing, the Company shall not be required to assume any increased economic burden.

 

(e)
Overall Compliance. In the event that
it is reasonably determined by the Company and Executive that, as a result of Code Section 409A, any of the payments that Executive
is entitled to under the terms of this Agreement or any nonqualified deferred compensation plan (as defined under Section 409A)
may not be made at the time contemplated by the terms hereof or thereof, as the case may be, without causing Executive to be subject
to an income tax penalty and interest, the Company will make such payment on the first day that would not result in Executive
incurring any tax liability under Section 409A.

 

(f)
Consultation with Tax Advisor. Executive
is hereby advised to consult immediately with his own tax advisor regarding the tax consequences of this Agreement, including
the consequences of Code Section 409A.
