EMPLOYMENT
AGREEMENT

 

THIS
EMPLOYMENT AGREEMENT (this “Agreement”), dated as of April 25, 2022 (the “Effective Date”),
is entered into by and between AST SpaceMobile, Inc., a Delaware corporation (the “Managing Member”), AST &
Science, LLC, a Delaware limited liability company (the “Operating Company”) and Sean Wallace (the “Executive”).
Certain capitalized terms used in this Agreement are defined in Section 11 below.

 

RECITALS

 

	 	A.	The
    Managing Member and the Operating Company (collectively, the “Company”) desire to employ the Executive
    as EVP Chief Financial Officer of the Managing Member and Operating Company, and to enter into an agreement embodying the terms of
    such employment; and
	 	 	 
	 	B.	The
    Executive desires to accept such employment, subject to the terms and conditions of this Agreement.

 

NOW,
THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

 

1.
Employment Period. Subject to the provisions for earlier termination hereinafter provided, the Executive’s employment hereunder
shall be for a term (the “Employment Period”) commencing as soon as practicable following April 30, 2022, taking
into consideration the Executive’s orderly departure from his current employer, but in no event later than May 13, 2022 (the actual
commencement date, the “Start Date”), and ending on the fourth (4th) anniversary of the Start Date
(the “Initial Termination Date”). If not previously terminated in accordance with this Agreement, the Employment
Period shall automatically be extended for one additional year immediately following the Initial Termination Date and on each subsequent
anniversary of the Initial Termination Date thereafter (each such extension, a “Renewal Term”), unless either
the Executive or the Company elects not to so extend the Employment Period by notifying the other party, in writing, of such election
(a “Non-Renewal”) not less than sixty (60) days prior to the last day of the Employment Period as then in effect.
Notwithstanding anything to the contrary in the foregoing, the Executive’s employment hereunder is terminable at will by the Company
or by the Executive at any time (for any reason or for no reason), subject to the provisions of Section 4 hereof.

 

2.
Terms of Employment.

 

(a)
Position and Duties.

 

(i)
During the Employment Period, the Executive shall serve as EVP Chief Financial Officer of the Managing Member and Operating Company,
and shall perform such employment duties as are usual and customary for such positions. The Executive shall report solely and
directly to the Chairman and Chief Executive Officer of the Company (currently Abel Avellan). At the Company’s request, the
Executive shall serve the Company and/or its subsidiaries and affiliates in other capacities in addition to the foregoing,
consistent with the Executive’s position as EVP Chief Financial Officer of the Managing Member and Operating Company. In the
event that the Executive serves in any one or more of such additional capacities, the Executive shall not be entitled to additional
compensation beyond that specified in Section 2(b) hereof unless approved by the Board or the Compensation Committee of the Board
(the “Compensation Committee”). In addition, in the event the Executive’s service in one or more of
such additional capacities is terminated, the Executive’s compensation, as specified in Section 2(b) hereof, shall not be
diminished or reduced in any manner as a result of such termination provided that the Executive otherwise remains employed under the
terms of this Agreement.

 

[CERTAIN IDENTIFIED INFORMATION HAS BEEN EXCLUDED
FROM THE EXHIBIT BECAUSE IT BOTH (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED]

 

    	1

     

    

 

(ii)
During the Employment Period, and excluding any periods of leave to which the Executive may be entitled (or physical or mental infirmity),
the Executive agrees to devote substantially all of his business time and attention to the business and affairs of the Company. Notwithstanding
the foregoing, during the Employment Period, it shall not be a violation of this Agreement for the Executive to: (A) serve on boards,
committees or similar bodies of charitable or nonprofit organizations, (B) fulfill limited teaching, speaking and writing engagements,
and (C) manage his personal passive investments, in each case, so long as such activities do not individually or in the aggregate materially
interfere or conflict with the performance of the Executive’s duties and responsibilities under this Agreement; provided, that
with respect to the activities in subclause (B), the Executive receives prior written approval from the Board of Directors of the Managing
Member (the “Board”) which approval shall not be unreasonably withheld. The Executive may serve on boards,
committees or similar bodies of for- profit organizations with the prior written approval of the Board.

 

(iii)
The Executive shall perform the services required by this Agreement at the Company’s principal offices located in Miami, Florida
(the “Principal Location”). From time to time, the Executive will also be required to travel to other locations
as may be necessary to fulfill the Executive’s duties and responsibilities hereunder.

 

(b)
Compensation, Benefits, Etc.

 

(i)
Base Salary. During the Employment Period, the Company shall pay to the Executive a base salary of no less than $250,000 per annum
(the “Base Salary”). The Base Salary shall be reviewed annually by the Compensation Committee and may be increased
from time to time by the Compensation Committee in its sole discretion. The Base Salary shall be paid in accordance with the Company’s
normal payroll practices for executive salaries generally, but no less often than monthly and shall be pro-rated for partial years of
employment. The Base Salary shall not be reduced from the initial Base Salary or after any increase in accordance herewith and the term
“Base Salary” as utilized in this Agreement shall refer to the Base Salary as so increased.

 

(ii) Benefits.
During the Employment Period, the Executive (and the Executive’s spouse and/or eligible dependents to the extent provided in
the applicable plans and programs) shall be eligible to participate in and be covered under the health and welfare benefit plans and
programs maintained by the Company for the benefit of its employees from time to time, pursuant to the terms of such plans and
programs including any medical, life, hospitalization, dental, disability, accidental death and dismemberment and travel accident
insurance plans and programs on the same terms and conditions as those applicable to similarly situated senior executives. In
addition, during the Employment Period, the Executive shall be eligible to participate in any retirement, savings and other employee
benefit plans and programs maintained from time to time by the Company for the benefit of its senior executive officers. Nothing
contained in this Section 2(b)(ii) or otherwise shall create or be deemed to create any obligation on the part of the Company to
adopt or maintain any health, welfare, retirement or other benefit plan or program at any time or to create any limitation on the
Company’s ability to modify or terminate any such plan or program; provided, that, the Executive shall be treated no less
favorably than other similarly situated senior executives in connection with any such modification or termination. The Company shall
provide the Executive with indemnification (and advancement of expenses) to the fullest extent permitted by applicable law and
directors’ and officers’ liability insurance coverage in each case no less favorable than provided to other senior
executives of the Company, including for services required for any subsidiary or affiliate.

 

    	2

     

    

 

(iii)
Equity Award. The Compensation Committee will grant the Executive an award of 700,000 restricted stock units (the “RSUs”,
and such award, the “Equity Award”) upon or within thirty days after the Start Date, subject to the Executive’s
continued service with the Company through the grant date. The RSUs subject to the Equity Award shall vest as follows: (A) 400,000 of
the RSUs conferred under the Equity Award (the “Time-Based Portion”) will be subject to time-based vesting,
with twenty-five percent (25%) of the RSUs vesting on each anniversary of the Start Date and (B) 300,000 RSUs underlying the Equity Award
(the “Performance-Based Portion”) will vest based on the vesting schedule set forth on Exhibit A attached
hereto. The additional terms and conditions of the Equity Award will be determined by the Compensation Committee and set forth in a separate
award agreement (the “Equity Award Agreement”) in a form prescribed by the Company (which terms and conditions
shall be no less favorable than the terms of equity awards provided to other senior executives generally), and the Equity Award will
be governed in all respects by the terms and conditions of the AST SpaceMobile, Inc. 2020 Incentive Award Plan and the applicable award
agreement.

 

(iv)
Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable business
expenses incurred by the Executive in accordance with the policies, practices and procedures of the Company provided to senior executives
of the Company. The Company shall reimburse (i) up to $5,000, payable monthly, for temporary housing in the Miami, Florida area until
the earlier of (x) the time that the Executive obtains permanent housing in the Miami, Florida area and (y) the six-month anniversary
of the Start Date, and (ii) up to $75,000 of additional direct out-of-pocket costs relating to the Executive’s relocation to the
Miami, Florida area (regardless of whether such costs are incurred prior to or following the Start Date), to be reimbursed in accordance
with the limitations set forth in Section 12(d)(iii) below (collectively, the “Relocation Reimbursement”) with
such reimbursable costs to be incurred, in each case, within the six months following the Start Date. In the event the Executive’s
employment is terminated by the Company for Cause or the Executive resigns (other than with Good Reason), in each case, on or prior to
the first anniversary of the Start Date, the Executive shall repay to the Company the Relocation Reimbursement. For the avoidance of
doubt, no repayment obligation shall exist (and all unpaid amounts of the Relocation Reimbursement, for which Executive has submitted
an expense report with receipts and other documentation, shall be paid to the Executive (or his estate, if applicable)), in the event
of the termination of the Executive’s employment by the Company without Cause, by reason of the Executive’s death or Disability,
or by the Executive with Good Reason. The Executive acknowledges and agrees that, to the extent the Relocation Reimbursement remains
subject to the repayment obligation contained in this Section 2(b)(iv), the Relocation Reimbursement shall be deemed to remain unearned
by the Executive. In the ordinary course and in accordance with applicable Company policy, the Executive will submit an expense report
with receipts and other documentation supporting the Executive’s relocation to Miami, Florida. The Company shall reimburse the
reasonable legal fees incurred by the Executive in connection with the negotiation and execution of this Agreement and all ancillary
agreements, up to a limit of $15,000.

 

(v) Fringe
Benefits. During the Employment Period, the Executive shall be eligible to receive such fringe benefits and perquisites as are
provided by the Company to its senior executives from time to time, in accordance with the policies, practices and procedures of the
Company, and shall receive such additional fringe benefits and perquisites as the Company may, in its discretion, from time-to-time
provide.

 

    	3

     

    

 

(vi)
Vacation. During the Employment Period, the Executive shall be entitled to paid vacation in accordance with the plans, policies,
programs and practices of the Company applicable to its senior executive officers.

 

3.
Termination of Employment.

 

(a)
Death or Disability. The Executive’s employment shall terminate automatically upon the Executive’s death during the
Employment Period. Either the Company or the Executive may terminate the Executive’s employment in the event of the Executive’s
Disability during the Employment Period.

 

(b)
Termination by the Company. The Company may terminate the Executive’s employment during the Employment Period for Cause
or without Cause by delivery of a Notice of Termination given in accordance with Section 12(b) at least thirty (30) days’ prior
to such termination. At its discretion, the Company may elect to pay the Executive in lieu of part or all of any notice period.

 

(c)
Termination by the Executive. The Executive’s employment may be terminated by the Executive for any or no reason by delivery
of a Notice of Termination given in accordance with Section 12(b) at least thirty (30) days’ prior to such resignation. Notwithstanding
the foregoing, the Company may in its discretion waive all or any portion of such resignation notice period without pay in lieu thereof.

 

(d)
Notice of Termination. Any termination of employment (other than due to the Executive’s death), shall be communicated by
a Notice of Termination to the other parties hereto given in accordance with Section 12(b) hereof. The failure by the Company to set
forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the
Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing the Company’s rights hereunder.

 

(e) Termination
of Offices and Directorships; Return of Property. Upon termination of the Executive’s employment for any reason, unless
otherwise specified in a written agreement between the Executive and the Company, the Executive shall be deemed to have resigned
from all offices, directorships, and other employment positions if any, then held with the Company, and shall take all actions
reasonably requested by the Company to effectuate the foregoing. In addition, upon the termination of the Executive’s
employment for any reason, the Executive agrees to return to the Company all documents of the Company and its affiliates (and all
copies thereof) and all other Company or Company affiliate property that the Executive has in his possession, custody or control.
Such Company property, if applicable, includes, without limitation: (i) any materials of any kind that the Executive knows contain
or embody any proprietary or confidential information of the Company or an affiliate of the Company (and all reproductions thereof),
(ii) computers (including, but not limited to, laptop computers, desktop computers and similar devices) and other portable
electronic devices (including, but not limited to, tablet computers), cellular phones/smartphones, credit cards, phone cards, entry
cards, identification badges and keys, and (iii) any correspondence, drawings, manuals, letters, notes, notebooks, reports,
programs, plans, proposals, financial documents, or any other documents concerning the customers, business plans, marketing
strategies, products and/or processes of the Company or any of its affiliates and any information received from the Company or any
of its affiliates regarding third parties. Notwithstanding the foregoing, the Executive shall be permitted to retain
Executive’s contacts, calendars and personal correspondence and copies of Executive’s own personnel, payroll and benefit
documents (provided that such documents do not contain any proprietary or confidential information of the Company or an affiliate of
the Company and that the Company has the prior opportunity to review, redact and/or retain any such documents containing such
confidential information).

 

    	4

     

    

 

(f)
Executive shall be under no obligation to seek other employment or to otherwise mitigate the obligations of the Company under this Agreement,
and there shall be no offset against amounts or benefits due to Executive under this Agreement or otherwise on account of any claim (other
than any preexisting debts then due in accordance with their terms) the Company may have against Executive or any remuneration or other
benefit earned or received by Executive after such termination.

 

4.
Obligations of the Company upon Termination.

 

(a)
Accrued Obligations. In the event that the Executive’s employment under this Agreement terminates during or upon expiration
of the Employment Period for any reason, the Company will pay or provide to the Executive: (i) any earned but unpaid Base Salary, (ii)
reimbursement of any business expenses incurred by the Executive prior to the Date of Termination that are reimbursable in accordance
with Section 2(b)(iv) hereof, to the extent timely substantiated by the Executive, (iii) any accrued vacation amounts, (iv) earned but
unpaid annual bonus amounts for the prior fiscal year and (v) any vested amounts due to the Executive under any plan, program or policy
of the Company (together, the “Accrued Obligations”). The Accrued Obligations described in clauses (i) –
(iv) of the preceding sentence shall be paid within 30 days after the Date of Termination (or such earlier date as may be required by
applicable law) and the Accrued Obligations described in clause (v) of the preceding sentence shall be paid in accordance with the terms
of the governing plan or program.

 

(b) Qualifying
Termination. Subject to Sections 4(c), 4(e) and 12(d), and the Executive’s continued compliance in all material respects
with the provisions of Section 7 hereof (provided, the Company provides the Executive with written notice of any failure to comply
and not less than thirty (30) days to cure, if curable), if the Executive’s employment with the Company is terminated during
the Employment Period due to a Qualifying Termination, then in addition to the Accrued Obligations:

 

(i)
Cash Severance. The Company shall pay the Executive an amount equal to 0.75 multiplied by the Base Salary (the “Severance”).
The Severance shall be paid in substantially equal installments in accordance with the Company’s normal payroll practices following
the Date of Termination, but shall commence on the first payroll date following the effective date of the Release (as defined below)
(the “Release Effective Date”), and amounts otherwise payable prior to such first payroll date shall be paid
on such date without interest thereon.

 

(ii) COBRA.
Subject to the Executive’s valid election to continue healthcare coverage under Section 4980B of the Code, the Company shall
continue to provide, during the COBRA Period (as defined below), the Executive and the Executive’s eligible dependents with
coverage under its group health plans at the same levels and the same cost to the Executive as would have applied if the
Executive’s employment had not been terminated based on the Executive’s elections in effect on the Date of Termination;
provided, however, that if the Company is unable to continue to cover the Executive (or the Executive’s dependents)
under its group health plans without incurring penalties (including without limitation, pursuant to Section 2716 of the Public
Health Service Act or the Patient Protection and Affordable Care Act) or causing the Executive to incur penalties or other
unfavorable tax consequences, then, in either case, an amount equal to each remaining Company subsidy shall thereafter be paid to
the Executive in substantially equal monthly installments over the continuation coverage period (or the remaining portion thereof).
For purposes of this Agreement, “COBRA Period” shall mean the period beginning on the Date of Termination
and ending on the nine (9)-month anniversary thereof, and in all events, if the Executive becomes eligible to participate in the
“group health plan” of any subsequent employer, then the COBRA Period shall instead terminate at the end of the calendar
month in which such eligibility begins (and the Executive agrees to give the Company prompt written notice of such
eligibility).

 

    	5

     

    

 

(iii)
Time-Based Equity Acceleration. To the extent the Time-Based Portion of the Equity Award, or any portion thereof, remains unvested
as of the Date of Termination, such Time-Based Portion shall accelerate and vest upon the Release Effective Date with respect to a number
of RSUs comprising the Time-Based Portion equal to (A), in the event a Qualifying Termination occurs on or prior to the one-year anniversary
of the Start Date, 100,000 RSUs, and (B) in the event a Qualifying Termination occurs after the one-year anniversary of the Start Date,
(x) (1) the number of days during the period commencing on the last vesting date prior to the Date of Termination (or the grant date
if there is no prior vesting date) and ending on the nine (9)-month anniversary of the Date of Termination, (2) divided by 365, and multiplied
by (y) 100,000 (rounded up to the nearest whole number) (and any such RSUs shall remain outstanding and eligible to vest upon the Release
Effective Date following the Date of Termination and shall lapse if the Release is not timely executed or is revoked).

 

(iv)
Performance-Based Equity Vesting Period Extension. Notwithstanding anything to the contrary, (A) any portion of the Initial Performance-Based
Portion (as defined in Exhibit A) of the Equity Award as to which the Initial Performance Target (as defined in Exhibit A)
has been satisfied as of the Date of Termination, or as to which the Initial Performance Target is satisfied within 120 days of the Date
of Termination, and (B) any portion of the Second Performance-Based Portion (as defined in Exhibit A) of the Equity Award as to
which the Second Performance Target (as defined in Exhibit A) has been satisfied as of the Date of Termination, or as to which
the Second Performance Target is satisfied within 120 days of the Date of Termination, shall, in the case of each of the preceding clauses
(A) and (B), vest on (x) the Release Effective Date, if the applicable performance target is attained on or prior to Release Effective
Date, or (y) the date of the attainment of the applicable performance target, if such date occurs after the Release Effective Date and
on or prior to the 120th day following the Date of Termination (and any such RSUs shall remain outstanding and eligible to
vest upon the later such date and shall lapse if the Release is not timely executed or is revoked and/or the applicable performance target
is not attained on or prior to the 120th day following the Date of Termination).

 

(c)
Release. Notwithstanding the foregoing, it shall be a condition to the Executive’s right to receive the amounts provided
for in Section 4(b) and 4(d) hereof that the Executive, or the Executive’s estate or beneficiaries, as applicable, execute and
deliver to the Company an effective release of claims in a form consistent with that used generally by the Company in connection with
the termination of similarly situated senior executives of the Company (the “Release”) within 21 days (or,
for the Executive’s estate or beneficiaries or to the extent required by law, 45 days) following the Date of Termination and that
the Executive, or the Executive’s estate or beneficiaries, as applicable, not revoke such Release during any applicable revocation
period. For the avoidance of doubt, all equity awards eligible for accelerated vesting pursuant to Section 4(b) and 4(d) hereof shall
remain outstanding and eligible to vest following the Date of Termination and shall actually vest and become exercisable (if applicable)
and non-forfeitable upon the effectiveness of the Release.

 

(d)
Other Terminations. If the Executive’s employment is terminated for any reason not described in Section 4(b) hereof, the
Company will pay the Executive only the Accrued Obligations; provided, that, upon the termination of the Executive’s employment
as a result of death or Disability, the Equity Award shall be treated as set forth in Sections 4(b)(iii) and (iv) as if such termination
of employment was a Qualifying Termination.

 

(e)
Six-Month Delay. Notwithstanding anything to the contrary in this Agreement, no compensation or benefits, including without limitation
any severance payments or benefits payable under this Section 4, shall be paid to the Executive during the six-month period following
the Executive’s Separation from Service if the Company determines in good faith that paying such amounts at the time or times indicated
in this Agreement would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is
delayed as a result of the previous sentence, then on the first day of the seventh month following the date of Separation from Service
(or such earlier date upon which such amount can be paid under Section 409A without resulting in a prohibited distribution, including
as a result of the Executive’s death), the Company shall pay the Executive a lump- sum amount equal to the cumulative amount that
would have otherwise been payable to the Executive during such period.

 

(f)
Exclusive Benefits. Except as expressly provided in this Section 4 and subject to Section 5 hereof, the Executive shall not be
entitled to any additional payments or benefits upon or in connection with the Executive’s termination of employment.

 

5.
Non-Exclusivity of Rights. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any
plan, policy, practice or program or any contract or agreement with the Company at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or contract or agreement except as explicitly modified by this Agreement.

 

6.
Excess Parachute Payments; Limitation on Payments.

 

(a)
Best Pay Cap. Notwithstanding any other provision of this Agreement, in the event that any payment or benefit received or to be
received by the Executive (including any payment or benefit received in connection with a termination of the Executive’s employment,
whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, including
the payments and benefits under Section 4 hereof, being hereinafter referred to as the “Total Payments”) would
be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”),
then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan,
arrangement or agreement, the cash severance payments under this Agreement shall first be reduced, and the noncash severance payments
hereunder shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax
but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local
income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions
attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction
(but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to
which the Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized
deductions and personal exemptions attributable to such unreduced Total Payments).

 

    	6

     

    

 

(b)
Certain Exclusions. For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise
Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such
manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account; (ii)
no portion of the Total Payments shall be taken into account which, in the written opinion of an independent, nationally recognized accounting
firm (the “Independent Advisors”) selected by the Company, does not constitute a “parachute payment”
within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the
Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Independent Advisors, constitutes
reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base
amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash
benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance
with the principles of Sections 280G(d)(3) and (4) of the Code. The Company shall pay all costs incurred by the Independent Advisors.

 

7.
Restrictive Covenants.

 

(a)
The Executive hereby acknowledges that the Executive has previously entered, or, concurrently with the execution of this Agreement, will
enter, into an agreement with the Company, effective as of the Start Date, containing confidentiality, intellectual property assignment

and conditions of the Confidentiality Agreement, and that such agreement shall be additional to, and not in limitation of, the covenants
contained in this Section 7.

 

(b)
Notwithstanding anything in this Agreement or the Confidentiality Agreement to the contrary, nothing contained in this Agreement shall
prohibit either party (or either party’s attorney(s)) from (i) filing a charge with, reporting possible violations of federal law
or regulation to, participating in any investigation by, or cooperating with the U.S. Securities and Exchange Commission, the Financial
Industry Regulatory Authority, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety
and Health Administration, the U.S. Commodity Futures Trading Commission, the U.S. Department of Justice or any other securities regulatory

or making other disclosures that are protected under the whistleblower provisions of applicable law or regulation, (ii) communicating
directly with, cooperating with, or providing information (including trade secrets) in confidence to any Government Agencies for the
purpose of reporting or investigating a suspected violation of law, or from providing such information to such party’s attorney(s)
or in a sealed complaint or other document filed in a lawsuit or other governmental proceeding, and/or (iii) receiving an award for information
provided to any Government Agency. Pursuant to 18 USC Section 1833(b), the Executive will not be held criminally or civilly liable under
any federal or state trade secret law for the disclosure of a trade secret that is made: (x) in confidence to a federal, state, or local
government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected
violation of law; or (y) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.
Further, nothing in this Agreement is intended to or shall preclude either party from providing truthful testimony in response to a valid
subpoena, court order, regulatory request or other judicial, administrative or legal process or otherwise as required by law or from
providing truthful testimony in connection with any legal process between the Executive and the Company or any of its affiliates. If
the Executive is required to provide testimony, then unless otherwise directed or requested by a Government Agency or law enforcement
or precluded by applicable law, the Executive shall notify the Company as soon as reasonably practicable after receiving any such request
of the anticipated testimony.

pursuant to the terms of this Agreement.

Cause (other than by reason of the Executive’s death or Disability), (ii) by the Executive with Good Reason or (iii) by reason

    	10

     

    

 

(c)
Sarbanes-Oxley Act of 2002. Notwithstanding anything herein to the contrary, if the Company determines, in its good faith judgment,
that any transfer or deemed transfer of funds hereunder is likely to be construed as a personal loan prohibited by Section 13(k) of the
Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”),
then such transfer or deemed transfer shall not be made to the extent necessary or appropriate so as not to violate the Exchange Act
and the rules and regulations promulgated thereunder.

 

(d)
Section 409A of the Code.

 

(i)
To the extent applicable, this Agreement shall be interpreted in accordance with Section 409A. Notwithstanding any provision of this
Agreement to the contrary, if the Company determines that any compensation or benefits payable under this Agreement may be subject to
Section 409A, the Company shall work in good faith with the Executive to adopt such amendments to this Agreement or adopt other policies
and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Company determines
are necessary or appropriate to avoid the imposition of taxes under Section 409A, including without limitation, actions intended to (i)
exempt the compensation and benefits payable under this Agreement from Section 409A, and/or (ii) comply with the requirements of Section
409A; provided, however, that this Section 12(d) shall not create an obligation on the part of the Company to adopt any
such amendment, policy or procedure or take any such other action, nor shall the Company have any liability for failing to do so.

 

(ii)
Any right to a series of installment payments pursuant to this Agreement is to be treated as a right to a series of separate payments.
To the extent permitted under Section 409A, any separate payment or benefit under this Agreement or otherwise shall not be deemed “nonqualified
deferred compensation” subject to Section 409A to the extent provided in the exceptions in Treasury Regulation Section 1.409A-1(b)(4),
Section 1.409A-1(b)(9) or any other applicable exception or provision of Section 409A. Any payments subject to Section 409A that are
subject to execution of a waiver and release which may be executed and/or revoked in a calendar year following the calendar year in which
the payment event (such as termination of employment) occurs shall commence payment only in the calendar year in which the consideration
period or, if applicable, release revocation period ends, as necessary to comply with Section 409A. All payments of nonqualified deferred
compensation subject to Section 409A to be made upon a termination of employment under this Agreement may only be made upon the Executive’s
Separation from Service.

 

(iii)
To the extent that any payments or reimbursements provided to the Executive under this Agreement are deemed to constitute compensation
to the Executive to which Treasury Regulation Section 1.409A-3(i)(1)(iv) would apply, such amounts shall be paid or reimbursed reasonably
promptly, but not later than December 31 of the year following the year in which the expense was incurred. The amount of any such payments
eligible for reimbursement in one year shall not affect the payments or expenses that are eligible for payment or reimbursement in any
other taxable year, and the Executive’s right to such payments or reimbursement of any such expenses shall not be subject to liquidation
or exchange for any other benefit.

 

(e)
Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability
of any other provision of this Agreement.

 

(f)
Withholding. The Company may withhold from any amounts payable under this Agreement such federal, state, local or foreign taxes
as shall be required to be withheld pursuant to any applicable law or regulation.

 

    	11

     

    

 

(g)
No Waiver. The Executive’s or the Company’s failure to insist upon strict compliance with any provision of this Agreement
or the failure to assert any right the Executive or the Company may have hereunder shall not be deemed to be a waiver of such provision
or right or any other provision or right of this Agreement.

 

(h)
Entire Agreement. As of the Effective Date, this Agreement (including the Confidentiality Agreement and the Equity Award Agreement),
constitutes the final, complete and exclusive agreement between the Executive and the Company with respect to the subject matter hereof
and replaces and supersedes any and all other agreements, offers or promises, whether oral or written, by any member of the Company and
its subsidiaries or affiliates, or representative thereof (including any employment offer letter between the Company and the Executive).
Notwithstanding anything herein to the contrary, this Agreement and the obligations and commitments hereunder shall neither commence
nor be of any force or effect prior to the Effective Date.

 

(i)
Arbitration.

 

(i)
Any controversy or dispute that establishes a legal or equitable cause of action (“Arbitration Claim”)
between any two or more Persons Subject to Arbitration (as defined below), including any controversy or dispute, whether based on
contract, common law, or federal, state or local statute or regulation, arising out of, or relating to the Executive’s service
or the termination thereof, shall be submitted to final and binding arbitration as the sole and exclusive remedy for such
controversy or dispute in accordance with the rules of JAMS pursuant to its Employment Arbitration Rules and Procedures, which are
available at http://www.jamsadr.com/rules-employment-arbitration/, and the Company will provide a copy upon the Executive’s
request. Notwithstanding the foregoing, this Agreement shall not require any Person Subject to Arbitration to arbitrate pursuant to
this Agreement any claims: (A) under a Company benefit plan subject to the Employee Retirement Income Security Act, as amended; or
(B) as to which applicable law not preempted by the Federal Arbitration Act prohibits resolution by binding arbitration. Either
party may seek provisional non-monetary remedies in a court of competent jurisdiction to the extent that such remedies are not
available or not available in a timely fashion through arbitration. It is the parties’ intent that issues of arbitrability of
any dispute shall be decided by the arbitrator.

 

(ii)
“Persons Subject to Arbitration” means, individually and collectively, (A) the Executive, (B) any person in
privity with or claiming through, on behalf of or in the right of the Executive, (C) the Company, (D) any past, present or future affiliate,
employee, officer, director or agent of the Company, and/or (E) any person or entity alleged to be acting in concert with or to be jointly
liable with any of the foregoing.

 

(iii)
The arbitration shall take place before a single neutral arbitrator at the JAMS office in Miami, Florida, or such other location as determined
by the arbitrator. Such arbitrator shall be provided through JAMS by mutual agreement of the parties to the arbitration; provided
that, absent such agreement, the arbitrator shall be selected in accordance with the rules of JAMS then in effect. The arbitrator
shall permit reasonable discovery. The award or decision of the arbitrator shall be rendered in writing; shall be final and binding on
the parties; and may be enforced by judgment or order of a court of competent jurisdiction.

 

(iv)
In the event of arbitration relating to this Agreement, each party shall be solely responsible for paying its own costs incurred in
connection with such arbitration, including, but not limited to, its own attorneys’ fees and/or its own witnesses’ fees.
The arbitrator may award fees and costs (including attorneys’ fees) to the prevailing party where authorized by applicable
law.

 

    	12

     

    

 

(v)
THE EXECUTIVE AND THE COMPANY UNDERSTAND THAT BY AGREEING TO ARBITRATE ANY ARBITRATION CLAIM, THEY WILL NOT HAVE THE RIGHT TO HAVE ANY
ARBITRATION CLAIM DECIDED BY A JURY OR A COURT, BUT SHALL INSTEAD HAVE ANY ARBITRATION CLAIM DECIDED THROUGH ARBITRATION.

 

(vi)
THE EXECUTIVE AND THE COMPANY WAIVE ANY CONSTITUTIONAL OR OTHER RIGHT TO BRING CLAIMS COVERED BY THIS AGREEMENT OTHER THAN IN THEIR INDIVIDUAL
CAPACITIES. EXCEPT AS MAY BE PROHIBITED BY LAW, THIS WAIVER INCLUDES THE ABILITY TO ASSERT CLAIMS AS A PLAINTIFF OR CLASS MEMBER IN ANY
PURPORTED CLASS OR REPRESENTATIVE PROCEEDING.

 

(vii)
This Section 12(i) shall be interpreted to conform to any applicable law concerning the terms and enforcement of agreements to arbitrate
service disputes. To the extent any terms or conditions of this Section 12(i) would preclude its enforcement, such terms shall be severed
or interpreted in a manner to allow for the enforcement of this Section 12(i). To the extent applicable law imposes additional requirements
to allow enforcement of this Section 12(i), this Agreement shall be interpreted to include such terms or conditions.

 

(j)
Amendment; Survival. No amendment or other modification of this Agreement shall be effective unless made in writing and signed
by the parties hereto. The respective rights and obligations of the parties under this Agreement shall survive the Executive’s
termination of employment and the termination of this Agreement to the extent necessary for the intended preservation of such rights
and obligations.

 

(k)
Counterparts. This Agreement and any agreement referenced herein may be executed in two or more counterparts, each of which shall
be deemed an original but which together shall constitute one and the same instrument.
