RECITALS


 


WHEREAS, the
Company currently employs Employee; and


 


WHEREAS, the
Company desires, for its continued success, to have the benefit of services of experienced management personnel like Employee and
thus believes it is in the best interest of the Company and its owners that Employee be reasonably secure in his employment and
position with the Company so that Employee can exercise independent judgment regarding the best interests of the Company and its
owners without distraction by uncertainties or risks regarding Employee’s continued employment with the Company that would
be created by the possibility of Employee’s termination by the Company not for Cause (as defined below) during the term of
this Agreement;


 


WHEREAS, the
Company believes it is in its best interests to provide Employee with certain severance benefits in the event Employee’s
employment with the Company and any of its Affiliates (as defined below) is terminated not for Cause by the Company, in order to
induce Employee to continue to provide employment services as described in this Agreement, and Employee desires to continue to
provide employment services as described herein; and


 


WHEREAS, Employee
agrees that the severance benefits referenced in this Agreement constitute a meaningful incentive for Employee to be reasonably
secure regarding Employee’s continued employment with the Company throughout the Employment Period (as defined below);

In the case of Employee’s
allegation of a Good Reason event, (i) Employee shall provide Notice to the Board or Compensation Committee of the event alleged
to constitute Good Reason within sixty (60) days of Employee’s knowledge of such event, and (ii) the Company shall have the

2.            Employment.


 


(a)          Employment
Period. Employee’s initial term of employment with the Company under this Agreement shall be for the period from the
Effective Date through December 31, 2018 (the “Initial Term”). Thereafter, Employee’s term of employment
shall be automatically extended repetitively for an additional one (1) year period on January 1, 2019, and each one-year anniversary
thereof, unless Notice of Termination (pursuant to Sections 1(p) and 5) is given by either the Company or Employee to the
other Party at least sixty (60) days prior to the end of the Initial Term or any one-year extension thereof, as applicable, that
the Agreement will not be renewed for a successive one-year period after the end of the current one-year period. Additionally,
the Company and Employee shall each have the right to give Notice of Termination to terminate this Agreement at will, with or without
Cause, at any time (including during the Initial Term and any extension thereof) subject, however, to the terms and conditions
of this Agreement regarding the rights and duties of the Parties following the Employment Termination Date. The Parties agree that
in the event of the death or disability (as such term is defined under Section 22(e)(3) of the Code) of Employee, the Company will
not be required to provide Notice of Termination to terminate this Agreement and the Agreement will automatically expire upon Employee’s
death or disability.


 


(b)          Employment.
Effective as of the Effective Date and continuing for the Employment Period, Employee’s employment by the Company shall be
subject to the terms and conditions of this Agreement.


 


(c)          Position.
As of the Effective Date, Employee will serve as President and Chief Executive Officer of the Company.


 


(d)          Duties
and Services. Employee agrees to serve in the position(s) referred to in Section 2(c) of this Agreement and
to perform the duties and services appertaining to such offices, as well as such additional duties and services appropriate
to such offices upon which the Parties mutually may agree from time to time. Employee’s employment shall also be subject
to the policies maintained and established by the Company from time to time, as the same may be amended or otherwise modified.


 


Employee shall at all
times use his best efforts to in good faith comply with United States and foreign laws applicable to Employee’s actions on
behalf of the Company and its Affiliates. Employee understands and agrees that he may be required to travel extensively at times
for purposes of the Company’s business.


 


(e)          Other
Interests. Employee agrees that, during the Employment Period, he will devote substantially all his business time to the business
and affairs of the Company and its Affiliates. The foregoing notwithstanding, the Parties recognize and agree that Employee may
engage in passive personal investments (such as real estate investments and rental properties) and other civic and charitable activities
(such as continued service on non-profit and/or educational boards) that do not materially conflict with the business and affairs
of the Company or materially interfere with Employee’s performance of his duties hereunder; provided, however, Employee agrees
that if the Compensation Committee or the CEO determines in good faith that continued service with one or more civic or charitable
entities is inconsistent with Employee’s duties hereunder and gives written notice to Employee, he will promptly resign from
each such position.

3.            Compensation
and Benefits.


 


(a)          Base
Salary. During the Employment Period, Employee shall receive a minimum annual base salary of $400,000, which shall be prorated
for any period of less than 12 months. The Company shall review Employee’s Base Salary on an annual basis and may, in
its sole discretion, increase (but not decrease) the Base Salary, and thereafter references in this Agreement to “Base Salary”
shall refer to annual Base Salary as adjusted. The Base Salary shall be paid in equal installments in accordance with the Company’s
standard policy regarding payment of compensation to executives, but no less frequently than monthly.


 


(b)          Reimbursement
of Business Expenses. During the Employment Period, subject to the Company’s standard policies and procedures with respect
to expense reimbursement as applied to its executives generally, the Company shall reimburse Employee for, or pay on behalf of
Employee, the reasonable and appropriate expenses incurred by Employee for business related purposes, including reasonable and
customary dues and fees to industry and professional organizations and costs of entertainment and business development.


 


(c)          Employee
and Executive Benefits Generally. During the Employment Period, Employee shall be eligible for participation in all employee
and executive benefit plans and programs of the Company, including without limitation, retirement and savings plans, medical and
life insurance plans, and other fringe benefits, as in effect from time to time, to the same extent as available to other officers
of the Company under the terms and conditions of such plans or programs. Nothing herein shall be construed to prevent the Company
(or other plan sponsor of any plan) from amending or terminating any such plan at any time, in its discretion, subject to the terms
and conditions of the plan.


 


(d)          Vacation
and Holidays. During the Employment Period, Employee shall be entitled initially to 25 days of paid vacation per calendar year,
as accrued in accordance with the Company’s vacation benefit policy. The Company may be converting to a Paid-Time-Off Policy
(“PTO”) and, upon such conversion, Employee’s vacation time will be replaced with PTO leave, as
applicable to similarly situated employees.


 


4.          Rights
and Payments Upon Termination. Employee’s right to compensation and benefits for periods after the Employment Termination
Date shall be determined in accordance with this Section 4, as follows:


 


(a)          Minimum
Payments. Employee shall be entitled to the following minimum payments under this Section 4(a), in addition to
any other payments or benefits to which he is entitled to receive under the terms of this Agreement or any employee benefit plan
or program:


 


(1)         Employee’s
accrued and unpaid Base Salary through the Employment Termination Date;


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 6




     


    

 


(2)         Employee’s
accrued and unused vacation days or PTO through the Employment Termination Date (subject to the terms and conditions of the vacation
policy and/or PTO policy); and


 


(3)         reimbursement
of Employee’s reasonable business expenses that were incurred but unpaid as of the Employment Termination Date.


 


Such salary and accrued
vacation days shall be paid to Employee within the next applicable pay period following the Employment Termination Date in a cash
lump sum less applicable withholdings. Business expenses shall be reimbursed in accordance with the Company’s normal policy
and procedures.


 


(b)          Severance
Payment. Subject to the other provisions of this Agreement, if Employee incurs a Qualifying Termination and timely executes
and returns to the Company (and does not revoke) a release of claims on the form provided to Employee by the Company for such purpose
at the time of Employee’s Qualifying Termination (the “Release”), as provided for in Section
15 of this Agreement, the Company shall:


 


(1)         pay
Employee (a) a lump sum cash payment equal to two (2) times the sum of Employee’s Base Salary, and (b) either (i) the target
bonus amount Employee is eligible to receive under the applicable Key Employee Incentive Plan as defined therein and if still effective
at the time of the Qualifying Termination or (ii) the amount Employee earned as a bonus in the year prior to the year of the Qualifying
Termination, whichever is the applicable and greater bonus amount (collectively, the “Severance Payment”),
less all required employment taxes and any other appropriate withholdings, on the first payroll date immediately following the
date that the Release becomes effective. In the event that the period for signing, returning and revoking the Release spans two
(2) tax years, the first payment will be paid in the second tax year; and


 


(2)         maintain
continued group health plan coverage following the Employment Termination Date under all group health plans subject to the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) (as codified in Code Section 4980B and
Part 6 of Subtitle B of Title I of ERISA) for Employee and Employee’s eligible spouse and dependents for the maximum period
for which such qualified beneficiaries are eligible to receive COBRA coverage. However, Employee (and Employee’s spouse and
dependents) shall not be required to pay more for such COBRA coverage than is charged by the Company to its officers who are then
in active service for the Company and receiving coverage under such plan and, therefore, the Company shall be responsible for the
difference between the amount charged hereunder and the full COBRA premiums. In all other respects, Employee (and Employee’s
spouse and dependents) shall be treated the same as other COBRA qualified beneficiaries under the terms of such plans and the provisions
of COBRA. In the event of any change to a group health plan following the Employment Termination Date, Employee and Employee’s
spouse and dependents, as applicable, shall be treated consistently with the then-current officers of the Company with respect
to the terms and conditions of coverage and other substantive provisions of the plan. Following the Employment Termination Date,
Employee and Employee’s spouse hereby agree to acquire and maintain any and all coverage that either or both of them are
entitled to at any time during their lives under the Medicare program or any similar program of the United States or any agency
thereof. Employee and Employee’s spouse further agree to pay any required premiums for Medicare coverage from their personal
funds.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 7




     


    

 


(c)          Limitation
on Severance Payment. For purposes of clarity, in the event of (i) resignation or other voluntary termination of Employee’s
employment by Employee without Good Reason, (ii) termination of Employee’s employment by the Company for Cause or (iii) termination
of Employee’s employment due to Employee’s death or “disability” (as such term is defined under Section
22(e)(3) of the Code), the Company shall have no obligation to provide the Severance Payment described in Section 4(b),
except to offer COBRA coverage (as required by COBRA) but not at the discounted rate described in Section 4(b)(2).
Employee shall still be entitled to receive the minimum payments provided under Section 4(a).


 


5.            Notice
of Termination. If the Company or Employee desires to terminate Employee’s employment hereunder at any time during,
as of, or prior to, expiration of the Employment Period, such Party shall do so by giving written Notice of Termination to the
other Party, provided that no such action shall alter or amend any other provisions hereof or rights arising hereunder. No further
renewals of Employee’s term of employment hereunder shall occur pursuant to Section 2(a) after the giving of
such Notice of Termination.


 


6.            No
Rights as an Owner. Employee shall not have any rights as an owner of the Company or any Affiliate as a result of this Agreement,
or as a result of any action taken (or omitted to be taken) by the Company or an Affiliate with respect to this Agreement.


 


7.            Restrictive
Covenants. As an inducement to the Company to enter into this Agreement, Employee represents to, and covenants with or in
favor of, the Company that Employee will comply with all of the restrictive covenants set out in Sections 8 through 12,
as a condition to the Company’s obligation to provide the Severance Payment and any other benefits to Employee under the
Agreement.

Secrets.

Secrets and Specialized Training and the other consideration provided to Employee under this Agreement, Employee agrees not to
disclose to any Person, or publish or use for any purpose, any Trade Secrets, except as required in the ordinary course of business
of the Company or an Affiliate or as authorized by the Board or Compensation Committee.

of Confidential Information.


 


(1)         Employee
acknowledges that Confidential Information has been and will be developed or acquired by the Company or an Affiliate through the
expenditure of substantial time, effort and money and provides the Company or an Affiliate with an advantage over competitors who
do not know or use the Confidential Information. Employee further acknowledges and agrees that the nature of the Confidential Information
obtained during Employee’s employment would make it difficult, if not impossible, for Employee to perform in a similar capacity
for a business competitive with the Company or an Affiliate without disclosing or utilizing Confidential Information.


 


(2)         During
and following Employee’s employment by the Company or an Affiliate, Employee shall hold in confidence and not directly or

an Affiliate. Employee agrees to give the Company Notice of any and all attempts to compel disclosure of any Confidential Information
within one (1) Business Day after Employee is informed that such disclosure is being, or will be, compelled. Such written Notice
shall include a description of the Confidential Information to be disclosed, the court, government agency, or other forum through
which the disclosure is sought, and the date by which the Confidential Information is to be disclosed, and shall contain a copy
of the subpoena, order or other process used to compel disclosure.


 


(3)         This
confidentiality covenant shall be in addition to, and shall not waive, limit or restrict in any way, any confidentiality provisions

Employee has any Trade Secrets or Confidential Information in Employee’s possession or under his control, Employee shall
immediately return same to the Company, including all copies thereof.


 


All writings, records,
and other documents and things comprising, containing, describing, discussing, explaining, or evidencing any Confidential Information
or Trade Secrets, and all equipment, computers, mobile phones, components, manuals, parts, keys, tools, and the like in Employee’s
custody, possession or under his control that have been obtained by, prepared by, or provided to, Employee by the Company or any
Affiliate in the course or scope of Employee’s employment with the Company (or any Affiliate) shall be the exclusive property
of the Company (or such Affiliate, as applicable), shall not be copied and/or removed from the premises of the Company or any Affiliate,
except in pursuit of the business of the Company or an Affiliate, and shall be delivered to the Company or an Affiliate, as applicable,
without Employee retaining any copies or electronic versions, within one (1) day following the Employment Termination Date or at
any other time requested by the Company.

11.         Inventions
and Other Works. Any and all writings, computer software, inventions, improvements, processes, procedures and/or techniques
which Employee may make, conceive, discover, or develop, either solely or jointly with any other Person, at any time during employment,
whether at the request or upon the suggestion of the Company or an Affiliate or otherwise, which relate to or are useful in connection
with any business now or hereafter carried on or contemplated by the Company or an Affiliate, including developments or expansions
of its present fields of operations, shall be the sole and exclusive property of the Company or an Affiliate, as applicable. Employee
agrees to take any and all actions necessary or appropriate so that the Company or the Affiliate can prepare and present applications
for copyright or Letters Patent therefor, and secure such copyright or Letters Patent wherever possible, as well as reissue renewals,
and extensions thereof, and obtain the record title to such copyright or patents. Employee shall not be entitled to any additional
or special compensation or reimbursement regarding any such writings, computer software, inventions, improvements, processes, procedures
and techniques.


 


12.         Non-Solicitation
Restriction. During employment and for a period of twelve (12) months after the
Employment Termination Date, Employee will not, whether for his own account or for the account of any other Person (other than
the Company or its Affiliates), intentionally solicit, endeavor to entice away from the Company or its Affiliates, or otherwise
interfere with the relationship of the Company or its Affiliates with any Person who is employed by the Company or an Affiliate
(including any independent consultants).


 


13.         Tolling.
If Employee violates any of the restrictions contained in Sections 10 through 12, then notwithstanding any provision
hereof to the contrary, the restrictive period will be suspended and will not run in favor of Employee from the time of the commencement
of any such violation, unless and until such time when Employee cures the violation to the reasonable satisfaction of the Board
or the Compensation Committee.


 


14.         Reformation.
If a court rules that any time period or the geographic area specified in any restrictive covenant in Sections 8 through 12
is unenforceable, then the time period will be reduced by the number of months, or the geographic area will be reduced by the elimination
of such unenforceable portion, or both, so that the restrictions may be enforced in the geographic area and for the time to the
full extent permitted by law.

15.         Release
Agreement. As a condition to the receipt of the Severance Payment under Section 4(b), Employee must first execute
the Release and return it to the Company. The Release shall be in substantially the same form as attached hereto as Exhibit
A (with any changes to such form as the Company may reasonably require, in its discretion, to reflect the circumstances relating
to the termination of Employee’s employment, any changes in applicable law or other legal authority, or any agreement by
the Company not to require a release with respect to one or more particular or potential claims). The Company shall deliver the
Release to Employee within five (5) Business Days after the Employment Termination Date. Employee must return the executed Release
within the twenty-one (21) or forty-five (45) day, whichever is applicable, period following the date of his receipt of the Release,
as applicable and stated in the Release. If the Release delivery and non-revocation period spans two taxable years, the Severance
Payment will always commence or be made in the second taxable year. The Company shall also execute the Release, after it has been
signed and returned by Employee, within three (3) Business Days after the end of the revocation period specified in the Release.
No Severance Payment shall be provided by the Company unless and until the Release has been executed by Employee, has not been
revoked, and is no longer subject to revocation by Employee. The Release shall not release any claim or cause of action by or on
behalf of Employee for (a) any payment or other benefit that is required under this Agreement prior to the receipt of such
benefit by or on behalf of Employee or (b) a breach of this Agreement by the Company.


 


16.         No
Additional Severance Payments. Employee acknowledges and agrees that he shall not be a participant in, and he hereby waives
any right to participate in, any severance pay plan (as the same may be amended from time to time) that generally covers employees
of the Company or an Affiliate such as to preclude duplicative severance pay benefits that are in addition to those provided to
Employee under the terms of this Agreement and, in such event, such other severance pay benefits shall not be provided to Employee.


 


17.         No
Disparaging Comments. Employee and the Company shall refrain from any criticisms or disparaging comments about the other Party;
provided, however, that nothing in this Agreement shall apply to or restrict in any way the communication of information to any
governmental law enforcement agency by either Party that is required by compulsion of law or for internal statements in the course
of performance of his duties for the Company. A violation or threatened violation of this prohibition may be enjoined by a court
of competent jurisdiction. The rights under this provision are in addition to any and all rights and remedies otherwise afforded
by law to the Parties.


 


Employee acknowledges
that in executing this Agreement, he has knowingly, voluntarily, and intelligently waived any free speech, free association, free
press or First Amendment to the United States Constitution (including, without limitation, any counterpart or similar provision
or right under any other state constitution which may be deemed to apply) and rights to disclose, communicate, or publish disparaging
information or comments concerning or related to the Company; provided, however, nothing in this Agreement shall be deemed to prevent
Employee from testifying fully and truthfully in response to a subpoena from any court or from responding to an investigative inquiry
from any governmental agency.


 


For all purposes of
the obligations of Employee under this Section 17, the term “Company” refers to the Company and its Affiliates,
and its and their directors, officers, employees, owners, partners and agents.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 12




     


    

 


18.         Tax
Withholding. The Company or its Affiliate shall withhold from any payments or benefits under this Agreement (whether or not
otherwise acknowledged under this Agreement) all federal, state, local, or other taxes that it is required to withhold.


 


19.         Employment
Status. Nothing in this Agreement provides Employee with any right to continued employment with the Company or any Affiliate,
or shall interfere with the right of the Company or an Affiliate to terminate Employee’s employment at any time subject to
their obligations under this Agreement.


 


20.         Company’s
Successor and Assignment. In addition to any obligations imposed by law upon any successor to the Company, this Agreement shall
be binding upon and inure to the benefit of the Company and any successor of the Company (whether direct or indirect, by purchase,
merger, consolidation or otherwise). The Company shall require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree
to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such
succession had taken place. As used in this Agreement, “Company” shall mean the Company, as previously defined, and
any successor by operation of law or otherwise, and any successor to the business and/or assets of the Company (as provided above)
which assumes and agrees to perform this Agreement.


 


21.         Employee’s
Successor. This Agreement is personal to Employee and shall not be assigned by Employee. Any purported assignment by Employee
shall be null and void from the initial date of the purported assignment. If Employee should die after the occurrence of a Qualifying
Termination event, but before any payment or other benefit to which Employee is entitled to receive under this Agreement has been
fully received by Employee, all payments or other benefits which Employee would have been entitled to receive had he continued
to live shall be made or provided in accordance with the terms of this Agreement to Employee’s surviving lawful spouse, if
any, or if not, to his estate upon receipt by the Company of proper instructions regarding the lawful representative of such estate.


 


22.         Restricted
Assignment. Except as expressly provided in Sections 20 and 21, this Agreement, and the rights and obligations of the
Parties hereunder, are personal in nature, and neither this Agreement, nor any right, benefit, or obligation of either Party hereto,
shall be subject to voluntary or involuntary assignment, alienation or transfer, whether by operation of law or otherwise, without
the prior written consent of the other Party. Any attempted assignment, transfer, or delegation in violation of the preceding sentence
shall be void and of no force or effect.


 


23.         Notice.
Each Notice or other communication required or permitted under this Agreement shall be in writing and transmitted or delivered
by personal delivery, prepaid courier or messenger service (whether overnight or same-day), prepaid telecopy or facsimile, or prepaid
certified United States mail (with return receipt requested), addressed (in any case) to the other Party at the address for that
Party set forth below that Party’s signature on this Agreement, or at such other address as the recipient has designated
by Notice to the other Party.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 13




     


    

 


Each Notice or communication
so transmitted, delivered, or sent in person, by courier or messenger service, or by certified United States mail, shall be deemed
given, received, and effective on the date delivered to or refused by the intended recipient (with the return receipt, or the equivalent
record of the courier or messenger, being deemed conclusive evidence of delivery or refusal.) Nevertheless, if the date of delivery
is after 5:00 p.m. (local time of the recipient) on a Business Day, the Notice or other communication shall be deemed given, received
and effective on the next Business Day.


 


24.         Waiver
and Amendment. No term or condition of this Agreement shall be deemed waived other than by a writing signed by the Party against
whom or which enforcement of the waiver is sought. Without limiting the generality of the preceding sentence, a Party’s failure
to insist upon the other Party’s strict compliance with any provision of this Agreement or to assert any right that a Party
may have under this Agreement shall not be deemed a waiver of that provision or that right. Any written waiver shall operate only
as to the specific term or condition waived under the specific circumstances, and shall not constitute a waiver of that term or
condition for the future or a waiver of any other term or condition. No amendment, termination or other modification of this Agreement
shall be effective unless stated in a writing signed by the Parties.


 


25.         Severability
and Reformation. It is the desire of the Parties hereto that this Agreement be enforced to the maximum extent permitted by
law, and should any provision contained herein be held invalid or otherwise unenforceable by a court of competent jurisdiction,
the Parties hereby agree that such provision shall be reformed to create a valid and enforceable provision to the maximum extent
permitted by law; provided, however, if such provision cannot be reformed, it shall be deemed ineffective and deleted herefrom
without affecting any other provision of this Agreement which shall remain fully enforceable. This Agreement should be construed
by limiting and reducing it only to the minimum extent necessary to be enforceable under applicable law. Any such determination
or reformation shall not be binding on any court or other governmental authority not otherwise bound to follow such conclusions
under applicable law.


 


26.         Compliance
with Code Section 409A. Any provisions of the Agreement that are subject to Code Section 409A and the regulations and other
authority issued thereunder by the appropriate governmental entity (“Section 409A”) are intended to comply
with all applicable requirements of Section 409A, or an exemption from the application of Section 409A, and shall be interpreted
and administered accordingly. Notwithstanding any provision of this Agreement to the contrary, a termination of employment shall
not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amount or benefit
that constitutes “non-qualified deferred compensation” (within the meaning of Section 409A) upon or following a termination
of Employee’s employment unless such termination is also a Separation from Service and, for purposes of any such provision,
references herein to a “termination,” “termination of employment” or like terms shall mean a Separation
from Service.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 14




     


    

 


Notwithstanding any
provision of this Agreement to the contrary, if any payment or other benefit provided herein would be subject to additional taxes
and interest under Section 409A because the timing of such payment is not delayed as required by Section 409A for a Specified Employee,
then if Employee is on the applicable date a Specified Employee, any such payment that Employee would otherwise be entitled to
receive during the first six months following his Separation from Service shall be accumulated and paid, within ten (10) days after
the date that is six months following the Employment Termination Date, or such earlier date upon which such amount can be paid
under Section 409A without being subject to such additional taxes and interest such as, for example, upon he Employee’s death.


 


With respect to any
amounts or benefits that are subject to Section 409A, this Agreement shall in all respects be administered in accordance with Section 409A.
Each payment under this Agreement shall be treated as a separate payment for purposes of Section 409A. In no event may Employee,
directly or indirectly, designate the calendar year of any payment to be made under this Agreement.


 


All reimbursements
and in-kind benefits provided under this Agreement that constitute deferred compensation within the meaning of Section 409A shall
be made or provided in accordance with the requirements of Section 409A. Within the time period permitted by Section 409A, the
Company may, in consultation with Employee, modify the Agreement in the least restrictive manner necessary and without any diminution
in the value of payments or other benefits to Employee hereunder, in order to avoid the imposition of accelerated tax, additional
tax and/or penalties on Employee under Section 409A.


 


Notwithstanding the
foregoing, the Company makes no representations, warranties, or guarantees regarding the tax treatment of this Agreement or the
Severance Payment under Section 409A or otherwise, and has advised Employee to obtain his own tax advisor regarding the tax consequences
of this Agreement.


 


27.         Cooperation.
Employee agrees that he will reasonably cooperate (taking into account his personal and professional schedule) in any litigation,
proceeding, investigation or inquiry in which the Company or any of its Affiliates may be or become involved. Employee also agrees
to reasonably cooperate with any internal investigation or inquiry conducted by or on behalf of the Company or an Affiliate. Such
cooperation shall include Employee making himself reasonably available (taking into account his personal and professional schedule),
upon the request of the Company or the Affiliate, or its counsel, for depositions, court appearances and interviews by such counsel.
The Company shall reimburse Employee for all reasonable and documented out-of-pocket expenses incurred by him in connection with
such cooperation. To the extent permitted by law, Employee agrees that he will notify the Board if he is contacted by any government
agency or any other Person contemplating or maintaining any claim or legal action against the Company or its Affiliate or by any
agent or attorney of such Person. Nothing contained in this Section 27 shall preclude Employee from providing truthful
testimony in response to a valid subpoena, court order, regulatory request or as may be required by law. Payment for expenses to
be reimbursed under this Section 27 may not be made after December 31st of the year following the year in which the
expense was incurred.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 15




     


    

 


28.         No
Duties; Waiver of Claims. Except to the extent required by any unwaiveable requirement under applicable law, no employee of
the Company (and none of its Affiliates) shall have any duties or liabilities, including without limitation any fiduciary duties,
to Employee (or any Person claiming by and through Employee) as a result of this Agreement or any Claim arising hereunder. To the
full extent permitted under applicable law, Employee irrevocably waives and releases any right or opportunity Employee might have
to assert (or participate or cooperate in) any Claim against any employee of the Company and any of its Affiliates arising out
of this Agreement. This Agreement does not create, nor shall it be construed as creating, any principal and agent, trust, or other
fiduciary duty or special relationship running from the Company to Employee.


 


29.         Limitation
of Liability. Employee’s sole remedy for any Disputes or Claims arising from this Agreement or any other agreement, Employee’s
employment or Employee’s relationship with the Company or any of its predecessors, successors, Affiliates, assigns, owners,
investors, agents, directors, officers, employees, consultants, committees, employee benefit plans and committees, fiduciaries,
representatives, insurers, attorneys, and all Persons acting by, through, under or in concert with any of them, shall be against
the Company. Employee shall have no claim or right of any nature against any Affiliate or any owner of the Company or against any
existing or former director, officer or employee of the Company or any of its Affiliates.


 


30.         No
Trust or Funding. The Company (and not any of its Affiliates) will be solely responsible for the payment of the Severance Payment
hereunder. This Agreement shall at all times be entirely unfunded and no provision shall at any time be made with respect to segregating
assets of the Company for payment of any Severance Payment or other benefit hereunder. This Agreement shall not create or be construed
to create a trust or separate fund of any kind or a fiduciary relationship between the Company and Employee. Neither Employee nor
any other Person shall have any interest in any particular assets of the Company (or any of its Affiliates) by reason of the right
to receive any payment or other benefit under this Agreement. To the extent that Employee acquires a right to receive any payment
from the Company pursuant to this Agreement, such right shall be no greater than the right of any general unsecured creditor of
the Company.


 


31.         Controlling
Law. This Agreement shall be governed by and construed under the laws of the State of Texas. Venue of any litigation arising
from this Agreement or any Disputes relating to this Agreement or Employee’s employment shall be in the United States District
Court for the Southern District of Texas, or a state district court of competent jurisdiction in Harris County, Texas. Employee
hereby consents and agrees to personal jurisdiction in these courts for any Dispute relating to or arising out of this Agreement
or to Employee’s employment, and Employee agrees that he shall not challenge personal or subject matter jurisdiction in such
courts for whatever reason.


 




    
	EMPLOYMENT AGREEMENT	 	PAGE 16

subject matter of this Agreement, (b) he has read this Agreement and understands its terms and conditions, (c) he has had
ample opportunity to discuss this Agreement with his legal counsel prior to execution, and (d) no strict rules of construction
shall apply for or against the drafter or any other Party. Employee represents that he is free to enter into this Agreement including,
without limitation, that he is not subject to any restrictive covenant that would conflict with his duties and covenants under
this Agreement.


 


33.         Survival
of Certain Provisions. Wherever appropriate to the intention of the Parties, the respective rights and obligations of the Parties
hereunder shall survive any termination or expiration of this Agreement.


 


34.         Entire
Agreement and Amendment. This Agreement constitutes the final and complete expression of agreement among the parties hereto
with respect to the subject matter hereof, and fully supersedes any and all prior agreements, understanding or representations
between the Company (or any Affiliate) and Employee pertaining to or concerning the subject matter of this Agreement. No oral statements
or prior written material not specifically incorporated in this Agreement shall be of any force and effect, and no changes in or
additions to this Agreement shall be recognized, unless incorporated in this Agreement by written amendment executed by both Parties,
such amendment to become effective on the date stipulated in it. Employee acknowledges and represents that he did not rely, and
has not relied, on any communications, promises, statements, inducements, or representations, oral or written, by the Company or
any Affiliate in connection with this Agreement. Employee confirms that he has relied solely and exclusively on Employee’s
own judgment in entering into this Agreement, and he expressly disclaims that he is owed any duty, including the duty of good faith
and fair dealing, that is not expressly set forth in this Agreement.

TO

EMPLOYMENT AGREEMENT


 


CONFIDENTIAL RELEASE AGREEMENT


 


In consideration of
the Severance Payment and other consideration described in that certain Employment Agreement dated as of November 17, 2017 (the
“Employment Agreement”), and as it may be amended thereafter, by and between EV Management, LLC (the
“Company”) and Michael E. Mercer (the “Employee”), this Release Agreement (this
“Agreement”) is made and entered into by the Company and Employee. The Company and Employee may be individually
referred to herein as “Party” and collectively as the “Parties.”


 


By signing this Agreement,
Employee and the Company hereby agree as follows:


 


		1.	Purpose. Terms used in this Agreement with initial capital letters that are not defined
herein are defined in the Employment Agreement between the Parties. The purpose of this Agreement is to provide for the orderly
termination of the employment relationship between the Parties, and to voluntarily resolve any actual or potential disputes or
claims that Employee has or might have, as of the date of Employee’s execution of this Agreement, against the Company and
all of its owners, parents, predecessors, successors, divisions, subsidiaries and Affiliates, and its and their present and former
agents, employees, managers, officers, directors, attorneys, owners, plan fiduciaries, assigns, representatives, Employees, consultants,
and all other Persons acting by, through, or in concert with any of them (individually and collectively, the “Released
Parties”). Neither the fact that this Agreement has been proposed or executed, nor the terms of this Agreement, are
intended to suggest, or should be construed as suggesting, that the Released Parties have acted unlawfully or violated any federal,
state or local law or regulation, or any other duty, policy or contract.



 


		2.	Termination of Employment. Effective ___________ (the “Termination Date”),
Employee’s employment with the Company and all of its Affiliates has terminated.



 


		3.	Termination Benefits. In consideration for Employee’s execution of, and required performance
under, this Agreement, the Company shall provide Employee with the Severance Payment (as such term is defined in Section 5(b) of
the Employment Agreement). Employee confirms and agrees that he would not otherwise have received, or been entitled to receive,
the Severance Payment or benefits other than those that are required to be provided under the Employee Retirement Income Security
Act of 1974, as amended (“ERISA”) or such other laws that cannot be waived. All payments hereunder shall
be net of withholding for applicable federal, state and local taxes to the extent required by law.



 


		4.	Waiver of Additional Compensation or Benefits. The Severance Payment to be paid to Employee
constitute the entire amount of compensation and consideration due to Employee under this Agreement, and Employee acknowledges
that he has no right to seek, and will not seek, any additional or different compensation or consideration for executing or performing
under this Agreement.



 




    	 	A-1	 



     


    

 


		5.	Neutral Employment Reference. The Company shall provide a neutral employment reference to
any potential employers that consider the employment of Employee or seek information concerning the reasons for the departure of
Employee. The Company will provide to any such potential employers the identity of the positions held by Employee and the dates
of Employee’s employment with the Company.



 


		6.	Tax Consequences. The Company has made no representations to Employee regarding the tax
consequences of any benefits received, or to be received, by Employee under the Employment Agreement.



 


		7.	Certain Continuing Obligations. Employee acknowledges and agrees that the post-termination
restrictive covenants and obligations that apply to Employee as set forth in the Employment Agreement shall survive termination
of the employment relationship and the execution of this Agreement, and Employee shall continue to fully honor his post-employment
obligations.



 


		8.	Employee Representations. Employee expressly agrees to and acknowledges, confirms and represents
to the following, and intends for the Company to rely upon the following in entering this Agreement:



 


(1)         The
term “Released Parties” means the Company and all of its Affiliates, and its and their present and former
employees, managers, officers, directors, owners, partners, agents, attorneys, owners, plan fiduciaries, representatives, and successors
and assigns, all other Persons acting by, through or in concert with any of them (collectively, the “Released Parties”).


 


(2)         Employee
has not filed any complaints, charges, claims or actions against the Company or any of the other Released Parties with any court,
agency, or commission regarding any of the matters related to this Agreement or to his employment or separation from service with
the Company. By executing this Agreement, Employee hereby waives the right to recover in any proceeding Employee may bring before
the federal Equal Employment Opportunity Commission (“EEOC”) or any state human rights commission, or
in any proceeding brought by the EEOC or any state human rights commission on Employee’s behalf, against the Company or any
of the other Released Parties.


 


(3)         Employee,
by entering into this Agreement, is releasing the Released Parties from any and all claims that Employee may have against them
under federal, state, or local laws, which have arisen on or before the Release Effective Date (as defined on the signature page
of this Agreement).


 


(4)         Employee,
by entering into this Agreement, is waiving all claims that Employee may have against the Released Parties under the federal Age
Discrimination in Employment Act of 1967, as amended (i.e., 29 USC § 621 et seq.), which have arisen on or before the
Release Effective Date.


 




    	 	A-2	 



     


    

 


(5)         Employee
has reviewed all aspects of this Agreement, and has carefully read and fully understands this Agreement.


 


(6)         Employee
has been hereby advised to consult with an attorney of his choice before signing this Agreement.


 


(7)         Employee

the advice of his attorney before entering into this Agreement.

represents and acknowledges that in executing this Release, he does not rely, and has not relied, on any prior oral or written
communications, promises, agreements, statements, inducements, understandings, or representations by the Company or any of the
Released Parties, except as expressly contained in this Agreement. Further, Employee expressly disclaims any reliance on any prior
oral or written communications, promises, agreements, statements, inducements, understandings, or representations in entering into
this Agreement and, therefore, Employee understands and agrees that he is precluded from bringing any fraud or similar claim against
the Company or any of the other Released Parties associated with any such communications, promises, agreements, statements, inducements,
understandings, or representations, and he is hereby entering into this Agreement based on his own independent judgment.


 


(10)        Employee
acknowledges that this Agreement shall be binding on Employee, and on his spouse, heirs, administrators, representatives, executors,
beneficiaries, successors and assigns.


 


(11)        Employee
agrees that this Agreement shall, in all cases, be construed as a whole, according to its fair meaning, and not strictly for or
against, either of the Parties.


 


(12)        Employee
does not waive any right or claim that initially arose for the first time after the Release Effective Date.


 


(13)        Employee
will receive payment of consideration under this Agreement that is beyond what Employee was entitled to receive before entering
into this Agreement.


 


(14)        Employee
understands and agrees that this Agreement shall not in any way be construed as an admission by the Released Parties of any unlawful
or wrongful acts whatsoever against Employee or any other Person; and the Released Parties specifically disclaim any liability
to, or wrongful acts against, Employee or any other Person.


 




    	 	A-3	 



     


    

 


		9.	Release. Employee, on behalf of himself and his spouse, heirs, administrators, representatives,
executors, beneficiaries, successors and assigns (individually and collectively, the “Releasing Parties”),
hereby fully, unconditionally and forever releases, acquits and discharges the Released Parties, jointly and severally, from and
against any and all claims, demands, actions, lawsuits, grievances, liabilities, and obligations of any nature whatsoever that
the Releasing Parties had, have or may ever have against the Released Parties, or that might be assigned by the Releasing Parties,
whether known or unknown, fixed or contingent, as of the Release Effective Date. Employee acknowledges, understands and agrees
that this Agreement specifically includes, without limitation, (a) law or equity claims; (b) contract (express or implied)
or tort claims; (c) claims arising under any federal, state or local laws of any jurisdiction that prohibit age, sex, race, national

of 2008, Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Civil Rights Acts of 1866 and/or 1871, 42

other federal, state, local, municipal or common law whistleblower protection, discrimination, wrongful discharge, anti-harassment
or anti-retaliation statute or ordinance; (e) claims arising under ERISA; or (f) any other statutory or common law claims related
to Employee’s employment or separation from employment with the Company or its Affiliate. Employee further represents that,
as of the Release Effective Date, he has not been the victim of any illegal or wrongful acts by any of the Released Parties, including,
without limitation, discrimination, retaliation, harassment or any other wrongful act based on sex, age, race, religion, or any
other legally protected characteristic.

investigating employment claims; provided, however, Employee hereby agrees that such filing or participation does not give Employee

and attorneys’ fees) against the Company or any of the other Released Parties based on his release of claims in this Agreement.
By executing this Agreement, Employee also hereby waives the right to recover monetary damages in any proceeding he may bring before

behalf, files, or causes to be filed, any such claim, charge, complaint, or action against the Company, any Affiliate, or other
