 WHEREAS, Executive is a party to an employment agreement with the Company, executed by Executive on
December 31, 2019 (the “Prior Agreement”); and 
 WHEREAS, the Company is contemplating either (i) an initial

WHEREAS, in anticipation of the Going Public Transaction, the Company desires to continue to employ Executive and to enter into this Agreement
embodying the terms of such continued employment, and Executive desires to enter into this Agreement and to accept such employment, subject to the terms and provisions of this Agreement; and 

WHEREAS, effective upon the closing of the Going Public Transaction (the “Closing”), without further action by the parties
hereto, the Company shall assign and shall cause PubCo to assume this Agreement, at which time, all references to the Company thereafter shall instead refer to PubCo. 

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are mutually acknowledged, the Company and Executive hereby agree as follows: 

Section 1.    Definitions. Capitalized terms not otherwise defined in this Agreement
shall have the meaning set forth on Appendix A, attached hereto. 

Section 2.    Acceptance and Term of Employment. 

The Company agrees to continue to employ Executive, and Executive agrees to continue to serve the Company, on the terms and conditions set
forth herein. Executive’s employment hereunder shall continue until terminated as provided in Section 7 hereof (the “Term of Employment”). 












 Section 3.    Position, Duties, and
Responsibilities; Place of Performance. 
 (a)    Position, Duties, and Responsibilities. During the Term of
Employment, Executive shall be employed and serve as the Chief Financial Officer of the Company, reporting directly to the Company’s Chief Executive Officer, and having such duties, authority and responsibilities commensurate with such position
and as may be reasonably assigned to Executive from time to time by the Company’s Chief Executive Officer or the Board. Executive also agrees to serve as an officer and/or director of any member of the Company Group, in each case without
additional compensation. 
 (b)    Performance. Executive shall devote Executive’s full business time,
attention, skill, and best efforts to the performance of Executive’s duties under this Agreement and shall not engage in any other business or occupation during the Term of Employment, including, without limitation, any activity that
(x) conflicts with the interests of the Company or any other member of the Company Group, (y) interferes with the proper and efficient performance of Executive’s duties for the Company, or (z) interferes with Executive’s
exercise of judgment in the Company’s best interests. Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving, with the prior written consent of the Board, as a member of the board of directors or advisory
board (or the equivalent in the case of a non-corporate entity) of a non-competing for-profit business and/or one or more
charitable organizations, (ii) engaging in charitable activities and community affairs, and (iii) managing Executive’s personal investments and affairs; provided, however, that the activities set out in clauses (i),
(ii), and (iii) shall be limited by Executive so as not to materially interfere, individually or in the aggregate, with the performance of Executive’s duties and responsibilities hereunder. 

(c)    Principal Place of Employment. Executive’s principal place of employment shall be at the Company’s
corporate headquarters, although Executive understands and agrees that Executive may be required to travel from time to time for business reasons. 

Section 4.    Compensation. 

During the Term of Employment, Executive shall be entitled to the following compensation: 

(a)    Base Salary. Executive shall be paid an annualized Base Salary (the “Base Salary”), payable
in accordance with the regular payroll practices of the Company, of $300,000, with increases, if any, as may be approved in writing by the Compensation Committee. 

(b)    Annual Bonus. Executive shall be eligible for an annual incentive bonus award determined by the Compensation
Committee in respect of each fiscal year during the Term of Employment (the “Annual Bonus”). The target Annual Bonus for each fiscal year shall be established by the Compensation Committee and not be less than $300,000 (the
“Target Annual Bonus”), with the actual Annual Bonus payable being based upon the level of achievement of annual Company and individual performance objectives for such fiscal year, as determined by the Compensation Committee and
communicated to Executive during the first 

  
 -2- 













 
quarter of such fiscal year. The Annual Bonus shall otherwise be subject to the terms and conditions of the annual bonus plan adopted by the Board or the Compensation Committee, if any, under
which bonuses are generally payable to senior executives of the Company, as in effect from time to time; provided, that the Annual Bonus shall be paid only in cash unless otherwise agreed in writing by Executive. The Annual Bonus shall be paid to
Executive at the same time as annual bonuses are generally payable to other senior executives of the Company subject to Executive’s continuous employment through the end of the fiscal year to which such bonus relates (subject to Section 7
below). 
 (c)    Equity Participation. In connection with the commencement of Executive’s employment
hereunder, Executive shall be entitled to participate in the equity incentive plan(s) of the Company as in effect from time to time and pursuant to the terms of such plan(s), the applicable award agreement and such other documents Executive is
required to execute in connection with the grant of any award under such plan(s) (the plan(s), the award agreement, and such other documents collectively, the “Equity Documents”). The terms of Executive’s equity awards shall be
exclusively governed by the terms of the Equity Documents. 
 (d)    Closing Equity Awards. Without limiting the
foregoing, subject to Executive’s continued employment hereunder through the Closing, upon or as soon as reasonably practicable following the Closing, Executive will be granted (i) shares of fully vested common stock of PubCo having a
value1 equal to $2 million (the “Stock Grant”), which Stock Grant shall be subject to any share lock-up provisions and any other
customary terms that are applicable generally to other executive shareholders of the Company, and (ii) shares of restricted common stock of PubCo having a value equal $1.5 million (the “Incentive Award” and together with
the Stock Grant, the “Equity Grants”). Forty percent (40%) of the Incentive Award shall vest on the first anniversary of the Closing, and the remaining sixty percent (60%) of the Incentive Award shall vest in substantially equal
annual installments over the next three (3) years, in each case based upon Executive’s continued employment hereunder, subject to acceleration of vesting upon any Change in Control or if Executive is terminated without Cause or resigns
with Good Reason, and shall otherwise be subject to the terms and conditions of the Equity Documents. 

(e)    Closing Bonus. In addition to the Equity Grants, and subject to Executive’s continued employment
hereunder through the Closing, upon the Closing, Executive shall be entitled to receive a one-time, lump-sum payment equal to $350,000, payable upon the next regularly
scheduled payroll date immediately following the Closing. 
 Section 5.    Employee
Benefits. 
 During the Term of Employment, Executive shall be entitled to participate in health, insurance, retirement, and other
benefits provided generally to senior executives of the Company. Executive shall also be entitled to the same number of holidays and sick days, as well as any other benefits, in each case as are generally allowed to senior executives of the Company

in accordance with the Company policy as in effect from time to time. You will also be entitled to four (4) weeks of vacation annually. Nothing contained herein shall be construed to limit
the Company’s ability to amend, suspend, or terminate any employee benefit plan or policy at any time, and the right to do so is expressly reserved so long as such amendment, suspension or termination is not particularly targeted at Executive.

 Section 6.    Reimbursement of Business Expenses. 

Executive is authorized to incur reasonable business expenses in carrying out Executive’s duties and responsibilities under this
Agreement, and the Company shall promptly reimburse Executive for all such reasonable business expenses, including, without limitation, airfare between Madison, Wisconsin and Las Vegas, Nevada until Executive’s family relocates to Las Vegas,
Nevada (expected to be in May 2021) subject to documentation in accordance with the Company’s policy, as in effect from time to time. 

Section 7.    Termination of Employment. 

(a)    General. The Term of Employment, and Executive’s employment hereunder, shall terminate upon the earliest
to occur of (i) Executive’s death, (ii) a termination by reason of a Disability, (iii) a termination by the Company with or without Cause, and (iv) a termination by Executive with or without Good Reason. Except as otherwise
expressly required by law (e.g., COBRA) or as specifically provided herein, all of Executive’s rights to future Base Salary, Annual Bonus, employee benefits and other compensatory amounts hereunder (if any) shall cease upon the
termination of Executive’s employment hereunder. 
 (b)    Deemed Resignation. Upon any termination of
Executive’s employment for any reason, except as may otherwise be requested by the Company in writing and agreed upon in writing by Executive, Executive shall be deemed to have resigned from any and all directorships, committee memberships, and
any other positions Executive holds with the Company or any other member of the Company Group. 
 (c)    Termination
Due to Death or Disability. Executive’s employment shall terminate automatically upon Executive’s death. The Company may terminate Executive’s employment immediately upon the occurrence of a Disability, such termination to be
effective upon Executive’s receipt of written notice of such termination. Upon Executive’s death or in the event that Executive’s employment is terminated due to Executive’s Disability, Executive or Executive’s estate or
Executive’s beneficiaries, as the case may be, shall be entitled to: 
 (i)    The Accrued
Obligations; 
 (ii)    Any unpaid Annual Bonus in respect of any completed fiscal year that has ended
prior to the date of such termination, which amount shall be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is 21/2 months following the last day of the fiscal year
in which such termination occurred; and 

  
 -4- 













 (iii)    An amount equal to (A) the Target Annual
Bonus multiplied by (B) a fraction, the numerator of which is the number of days elapsed from the commencement of the fiscal year in in which such termination occurs through the date of such termination and the denominator of which is 365 (or
366, as applicable), which amount shall be paid within thirty (30) days of Executive’s termination date. 
 Following Executive’s death or a
termination of Executive’s employment by reason of a Disability, except as set forth in this Section 7(c), Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

(d)    Termination by the Company for Cause. 

(i)    The Company may terminate Executive’s employment at any time upon the occurrence of an act
constituting Cause, effective upon delivery to Executive of written notice of such termination; provided, however, that with respect to termination relying on clause (ii), (vi) or (vii) of the definition of Cause, to the
extent that such act or acts or failure or failures to act are curable, Executive shall be given not less than ten (10) business days’ written notice by the Board of the Company’s intention to terminate Executive for Cause, such
notice to state in detail the particular act or acts or failure or failures to act that constitute the grounds on which the proposed termination for Cause is based, and such termination shall be effective at the expiration of such ten
(10) business day notice period unless Executive has cured such act or acts or failure or failures to act that give rise to Cause during such period. 

(ii)    In the event that the Company terminates Executive’s employment for Cause, he shall be
entitled only to the Accrued Obligations. Following such termination of Executive’s employment for Cause, except as set forth in this Section 7(d)(ii), Executive shall have no further rights to any compensation or any other benefits under
this Agreement. 
 (e)    Termination by the Company without Cause. The Company may terminate Executive’s
employment at any time without Cause, effective upon delivery to Executive of written notice of such termination. In the event that Executive’s employment is terminated by the Company without Cause (other than due to death or Disability),
Executive shall be entitled to: 
 (i)    The Accrued Obligations; 

(ii)    Any unpaid Annual Bonus in respect of any completed fiscal year that has ended prior to the date of
such termination, which amount shall be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is 21/2 months following the last day of the fiscal year in which such
termination occurred; 
 (iii)    Subject to satisfaction of the applicable performance objectives
applicable for the fiscal year in which such termination occurs, an amount equal to (A) the Annual Bonus otherwise payable to Executive for the fiscal year in which such termination occurred, assuming Executive had remained employed through the
applicable 

  
 -5- 













 
payment date, multiplied by (B) a fraction, the numerator of which is the number of days elapsed from the commencement of such fiscal year through the date of such termination and the
denominator of which is 365 (or 366, as applicable), which amount shall be paid at such time annual bonuses are paid to other senior executives of the Company, but in no event later than the date that is 21/2 months following the last day of
the fiscal year in which such termination occurred; and 
 (iv)    Continuation of Base Salary during the
Severance Term, payable in accordance with the Company’s regular payroll practices. 
 Notwithstanding the foregoing, the payments and benefits
described in clauses (ii) through (iv) above shall immediately terminate, and the Company shall have no further obligations to Executive with respect thereto, in the event that Executive breaches any provision set forth in Section 9
hereof. Following such termination of Executive’s employment by the Company without Cause, except as set forth in this Section 7(e), Executive shall have no further rights to any compensation or any other benefits under this Agreement.

 (f)    Termination by Executive with Good Reason. Executive may terminate Executive’s employment with
Good Reason by providing the Company thirty (30) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written notice, to be effective, must be provided to the Company within ninety
(90) days of the occurrence of such event. During such thirty (30) day notice period, the Company shall have a cure right (if curable), and if not cured within such period, Executive’s termination will be effective upon the expiration
of such cure period, and Executive shall be entitled to the same payments and benefits as provided in Section 7(e) hereof for a termination by the Company without Cause, subject to the same conditions on payment and benefits as described in
Section 7(e) hereof. Following such termination of Executive’s employment by Executive with Good Reason, except as set forth in this Section 7(f), Executive shall have no further rights to any compensation or any other benefits under
this Agreement. 
 (g)    Termination by Executive without Good Reason. Executive may terminate Executive’s
employment without Good Reason by providing the Company thirty (30) days’ written notice of such termination. In the event of a termination of employment by Executive under this Section 7(g), Executive shall be entitled only to the
Accrued Obligations. In the event of termination of Executive’s employment under this Section 7(g), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the
characterization of such termination as a termination by Executive without Good Reason. Following such termination of Executive’s employment by Executive without Good Reason, except as set forth in this Section 7(g), Executive shall have
no further rights to any compensation or any other benefits under this Agreement. 
 (h)    Release.
Notwithstanding any provision herein to the contrary, the payment of any amount or provision of any benefit pursuant to subsection (e) or (f) of this Section 7 other than the Accrued Obligations (collectively, the “Severance
Benefits”) shall be conditioned upon Executive’s execution, delivery to the Company, and non-revocation of the Release of Claims (and the expiration of any revocation period contained in such
Release of Claims) within sixty (60) days following the date of Executive’s termination of employment 

  
 -6- 













 
hereunder (the “Release Execution Period”). If Executive fails to execute the Release of Claims in such a timely manner so as to permit any revocation period to expire prior to
the end of such sixty (60) day period, or timely revokes Executive’s acceptance of such release following its execution, Executive shall not be entitled to any of the Severance Benefits. No portion of the Severance (other than Accrued
Obligations) shall be paid until the Release of Claims has become effective and all such amounts shall commence to be paid on the first regular payroll date of the Company after the Release of Claims has become effective; provided, that, if
the Release Execution Period overlaps two calendar years, the first payment shall not be made sooner than the first day of the second year, and shall include any missed payments. 

Section 8.    Certain Payments. 

In the event that (a) Executive is entitled to receive any payment, benefit or distribution of any type to or for the benefit of
Executive, whether paid or payable, provided or to be provided, or distributed or distributable, pursuant to the terms of this Agreement or otherwise (collectively, the “Payments”), and (b) the net after-tax amount of such Payments, after Executive has paid all taxes due thereon (including, without limitation, taxes due under Section 4999 of the Code) is less than the net
after-tax amount of all such Payments otherwise due to Executive in the aggregate, if such Payments were reduced to an amount equal to 2.99 times Executive’s “base amount” (as defined in
Section 280G(b)(3) of the Code), then the aggregate amount of such Payments payable to Executive shall be reduced to an amount that will equal 2.99 times Executive’s base amount. To the extent such aggregate “parachute payment”
(as defined in Section 280G(b)(2) of the Code) amounts are required to be so reduced, the parachute payment amounts due to Executive (but no non-parachute payment amounts) shall be reduced in the
following order: (i) the parachute payments that are payable in cash shall be reduced (if necessary, to zero) with amounts that are payable last reduced first; (ii) payments and benefits due in respect of any equity, valued at full value
(rather than accelerated value), with the highest values reduced first (as such values are determined under Treasury Regulation Section 1.280G-1, Q&A 24); and (iii) all other non-cash benefits not otherwise described in clause (ii) of this Section 8 reduced last. 

Section 9.    Restrictive Covenants. 

(a)    General. Executive acknowledges and recognizes the highly competitive nature of the business of the Company
Group, that access to Confidential Information renders Executive special and unique within the industry of the Company Group, and that Executive will have the opportunity to develop substantial relationships with existing and prospective clients,
accounts, customers, consultants, contractors, investors, and strategic partners of the Company Group during the course of and as a result of Executive’s employment with the Company. In light of the foregoing, as a condition of Executive’s
employment by the Company, and in consideration of Executive’s employment hereunder and the compensation and benefits provided herein, Executive acknowledges and agrees to the covenants contained in this Section 9. Executive further
recognizes and acknowledges that the restrictions and limitations set forth in this Section 9 are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and
assets of the Company Group.

 (b)    Confidential Information. 

(i)    Executive acknowledges that, during the Term of Employment, Executive will have access to
information about the Company Group and that Executive’s employment with the Company shall bring Executive into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing, Executive agrees,
at all times during the Term of Employment and thereafter, to hold in confidence, and not to use, except for the benefit of the Company Group, or to disclose to any Person without written authorization of the Company, any Confidential Information;
provided, that nothing in this Section 9(b)(i) shall prevent Executive from disclosing Confidential Information as may be required by applicable law, rule or court order and nothing shall prevent Executive from disclosing the terms of this
Agreement to his attorneys and other advisors on a need-to-know basis. 

(ii)    Nothing in this Agreement shall prohibit or impede Executive from communicating, cooperating or
filing a complaint with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. federal, state or
local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures
are consistent with applicable law. Executive understands and acknowledges that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in
confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding,
if such filing is made under seal. Executive understands and acknowledges further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the
individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Moreover, Executive is not
required to give prior notice to (or get prior authorization from) the Company regarding any such communication or disclosure. Notwithstanding the foregoing, under no circumstance will Executive be authorized to disclose any information covered by
attorney-client privilege or attorney work product of any member of the Company Group without prior written consent of Company’s General Counsel or other officer designated by the Company. Participant does not need the prior authorization of
(or to give notice to) any member of the Company Group regarding any communication, disclosure, or activity permitted by this paragraph. 

(c)    Assignment of Intellectual Property. 

(i)    Executive agrees that he will, without additional compensation, promptly make full written
disclosure to the Company, and will hold in trust for the sole right and benefit of the Company all developments, original works of authorship, inventions, concepts, know-how, improvements, trade secrets, and
similar proprietary 

  
 -8- 













 
rights, whether or not patentable or registrable under copyright or similar laws, which Executive may (or have previously) solely or jointly conceive or develop or reduce to practice, or cause to
be conceived or developed or reduced to practice, during the Term of Employment, whether or not during regular working hours, provided they arise out of Executive’s employment with the Company or are developed through the use of equipment,
supplies, or facilities of any member of the Company Group, or any Confidential Information, or in consultation with personnel of any member of the Company Group (collectively referred to as “Developments”). Executive further
acknowledges that all Developments made by Executive (solely or jointly with others) within the scope of and during the Term of Employment are “works made for hire” (to the greatest extent permitted by applicable law) for which Executive
is, in part, compensated by Executive’s Base Salary, unless regulated otherwise by law, but that, in the event any such Development is deemed not to be a work made for hire, Executive hereby assigns to the Company, or its designee, all
Executive’s right, title, and interest throughout the world in and to any such Development. 

(ii)    Executive agrees to reasonably assist the Company, or its designee, at the Company’s expense,
in every way to secure the rights of the Company Group in the Developments and any copyrights, patents, trademarks, service marks, database rights, domain names, mask work rights, moral rights, and other intellectual property rights relating thereto
in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments that the
Company shall deem necessary in order to apply for, obtain, maintain, and transfer such rights and in order to assign and convey to the Company Group the sole and exclusive right, title, and interest in and to such Developments, and any intellectual
property and other proprietary rights relating thereto. Executive further agrees that Executive’s obligation to execute or cause to be executed, when it is in Executive’s power to do so, any such instrument or papers shall continue after
the termination of the Term of Employment until the expiration of the last such intellectual property right to expire in any country of the world; provided, however, that the Company shall reimburse Executive for Executive’s
reasonable expenses incurred in connection with carrying out the foregoing obligation. If the Company is unable because of Executive’s mental or physical incapacity or unavailability for any other reason to secure Executive’s signature to
apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company as above, then Executive hereby irrevocably designates and
appoints the Company and its duly authorized officers and agents as Executive’s agent and attorney in fact to act for and in Executive’s behalf and stead to execute and file any such applications or records and to do all other lawfully
permitted acts to further the application for, prosecution, issuance, maintenance, and transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. Executive hereby waives and irrevocably
quitclaims to the Company any and all claims, of any nature whatsoever, that Executive now or hereafter have for past, present, or future infringement of any and all proprietary rights assigned to the Company.

 (d)    Non-Competition.
During the Term of Employment and the Post-Termination Restricted Period, Executive shall not, directly or indirectly engage in, have any equity interest in, or manage, provide services to or operate any person, firm, corporation, partnership or
business (whether as director, officer, employee, agent, representative, partner, member, security holder, consultant or otherwise) that engages in any business, directly or indirectly (through a subsidiary or otherwise), which competes with the
Business within the United States of America or any other jurisdiction in which any member of the Company Group engages in business, derives a material portion of its revenues or has demonstrable plans to commence business activities in.
Notwithstanding the foregoing, Executive may at any time own, for investment purposes only, up to three percent (3%) of the equity of any publicly-held company whose equity is either listed on a national stock exchange or on the NASDAQ National
Market System. 
 (e)    Non-Interference. During the Term of Employment
and the Post-Termination Restricted Period, Executive shall not, directly or indirectly for Executive’s own account or for the account of any other Person, engage in Interfering Activities. 

(f)    Return of Documents. In the event of Executive’s termination of employment hereunder for any reason,
Executive shall deliver to the Company (and will not keep in Executive’s possession, recreate, or deliver to anyone else) or destroy, at Executive’s sole option, any and all Confidential Information and all other documents, materials,
information, and property otherwise belonging to the Company Group; provided, that Executive shall be entitled to retain his personal contacts, digital or physical rolodex and/or any other personal property he may keep in his office. 

(g)    Independence; Severability; Blue Pencil. Each of the rights enumerated in this Section 9 shall be
independent of the others and shall be in addition to and not in lieu of any other rights and remedies available to the Company Group at law or in equity. If any of the provisions of this Section 9 or any part of any of them is hereafter
construed or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of this Section 9, which shall be given full effect without regard to the invalid portions. If any of the covenants contained herein are held to be
invalid or unenforceable because of the duration of such provisions or the area or scope covered thereby, each of the Company and Executive agree that the court making such determination shall have the power to reduce the duration, scope, and/or
area of such provision to the maximum and/or broadest duration, scope, and/or area permissible by law, and in its reduced form said provision shall then be enforceable. 

(h)    Injunctive Relief. Executive expressly acknowledges that any breach or threatened breach of any of the terms
and/or conditions set forth in this Section 9 may result in substantial, continuing, and irreparable injury to the members of the Company Group. Therefore, Executive hereby agrees that, in addition to any other remedy that may be available to
the Company, any member of the Company Group shall be entitled to seek injunctive relief, specific performance, or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this
Section 9. Notwithstanding any other provision to the contrary, Executive acknowledges and agrees that the Post-Termination Restricted Period shall be tolled during any period of violation of any of the covenants in this Section 9 and
during any other period required for litigation during which the Company or any other member of the Company Group seeks to enforce such covenants against Executive if it is ultimately determined that Executive was in breach of such covenants. 

  
 -10- 













 (i)    Disclosure of Covenants. As long as it remains in effect,
Executive will disclose the existence of the covenants contained in this Section 9 to any prospective employer, partner, co-venturer, investor, or lender prior to entering into an employment, partnership, or other business relationship with
such Person or entity. 
 (j)    Other Covenants. Notwithstanding anything contained in this Agreement to the
contrary, in the event that Executive is subject to similar restrictive covenants pursuant to any other agreement with any member of the Company Group, including, without limitation, under the Equity Documents (“Other Covenants”),
the covenants contained in this Agreement shall be in addition to, and not in lieu of, any such Other Covenants, and enforcement by the Company of the covenants contained in this Agreement shall not preclude the applicable member of the Company
Group from enforcing such Other Covenants in accordance with their terms. 

Section 10.    Representations and Warranties of Executive. 

Executive represents and warrants to the Company that:

 (b)    Each payment in a series of payments hereunder shall be deemed to be
a separate payment for purposes of Section 409A of the Code. 
 (c)    Notwithstanding anything herein to the
contrary, the payment (or commencement of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Executive
has also undergone a “separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Executive’s termination
of employment hereunder) shall be paid (or commence to be paid) to Executive on the schedule set forth in this Section 7 as if Executive had undergone such termination of employment (under the same circumstances) on the date of Executive’s
ultimate “separation from service.” 
 (d)    To the extent that any right to reimbursement of expenses or
payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made
by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be
subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses
eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, however, that the foregoing clause shall not be violated with regard to expenses reimbursed
under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

 (e)    While the payments and benefits provided hereunder are intended
to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, and shall be interpreted in a manner consistent with such intention, in no event whatsoever shall any member of the Company Group be
liable for any additional tax, interest, or penalties that may be imposed on Executive as a result of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other than for withholding obligations or
other obligations applicable to employers, if any, under Section 409A of the Code). 

Section 14.    Successors and Assigns; No Third-Party Beneficiaries. 

(a)    The Company. This Agreement shall inure to the benefit of the Company and its respective successors and
assigns. Except as expressly contemplated in the introductory clauses of this Agreement, neither this Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to a Person (other than another member
of the Company Group, or its or their respective successors) without Executive’s prior written consent (which shall not be unreasonably withheld, delayed, or conditioned); provided, however, that in the event of a sale of all or
substantially all of the assets of the Company or any direct or indirect division or subsidiary thereof to which Executive’s employment primarily relates, the Company may provide that this Agreement will be assigned to, and assumed by, the
acquiror of such assets, division or subsidiary, as applicable, without Executive’s consent. 

(b)    Executive. Executive’s rights and obligations under this Agreement shall not be transferable by
Executive by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder shall be paid in accordance with the terms of this
Agreement to Executive’s devisee, legatee, or other designee, or if there be no such designee, to Executive’s estate. 

(c)    No Third-Party Beneficiaries. Except as otherwise set forth in Section 7(c) or Section 14(b)
hereof, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Executive any legal or equitable right, remedy, or claim under or with respect to
this Agreement or any provision of this Agreement. 
 Section 15.    Indemnity. 

Except as otherwise provided herein, the Company (and following the Closing, PubCo) will, to the maximum extent permitted by law, defend,
indemnify and hold harmless Executive and Executive’s heirs, estate, executors and administrators against any costs, losses, claims, suits, proceedings, damages or liabilities to which Executive may become subject which arise out of, are based
upon or relate to Executive’s employment by the Company, including without limitation reimbursement for any legal or other expenses reasonably incurred by Executive in connection with the investigation of and defense against any such claims,
suits, or proceedings. Notwithstanding the foregoing, however, the Company’s obligation to defend, indemnify and hold harmless contained in this Section shall not apply to claims between the 

  
 -13- 













 
Company and Executive (including Executive’s heirs, estate, executors and administrators) including, without limitation, disputes arising out of the terms of this Agreement, nor shall it
apply to any claims or suits successfully adjudicated on the merits against Executive based upon Executive’s willful misconduct or gross negligence or Executive’s breach of any term of this Agreement (in which event Executive shall
promptly return to the Company all legal and other expenses paid on Executive’s behalf). 

Section 16.    Waiver and Amendments. 

Any waiver, alteration, amendment, or modification of any of the terms of this Agreement shall be valid only if made in writing and signed by
each of the parties hereto; provided, however, that any such waiver, alteration, amendment, or modification must be consented to on the Company’s behalf by the Board. No waiver by either of the parties hereto of their rights
hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver specifically states that it is to be construed as a continuing waiver. 

Section 17.    Severability. 

If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of
competent jurisdiction, (a) the remaining terms and provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that
comes closest to expressing the intention of the invalid or unenforceable term or provision hereof. 

Section 18.    Governing Law; Waiver of Jury Trial; Arbitration. 

THIS AGREEMENT IS GOVERNED BY AND IS TO BE CONSTRUED UNDER THE LAWS OF THE STATE OF NEVADA. EACH PARTY TO THIS AGREEMENT ALSO HEREBY WAIVES ANY
RIGHT TO TRIAL BY JURY IN CONNECTION WITH ANY SUIT, ACTION, OR PROCEEDING UNDER OR IN CONNECTION WITH THIS AGREEMENT.

shall be mailed to or delivered to the party for whom or which it is intended at such address as may from time to time be designated by it in a notice mailed or delivered to the other party as herein provided; provided, however, that

Executive may be given to Executive personally or may be mailed to Executive at Executive’s last known address, as reflected in the Company’s records. A copy (which such copy shall not constitute notice) of any notice to be delivered to
