 PREAMBLE 

The Company desires to employ the Executive, and the Executive desires to be employed by the Company, upon the terms and
subject to the conditions set forth in this Agreement. Therefore, the parties agree as follows with the intent to be legally bound. 

AGREEMENT 

1. Employment. The Company shall employ the Executive, and the Executive accepts employment with the
Company, upon the terms and subject to the conditions set forth in this Agreement. 
 2. Position and
Duties. During the Term (as defined below), the Executive shall be employed by the Company as its Executive Chairman and shall have duties, responsibilities and authority commensurate with such position, including (a) those assigned to
the Executive Chairman in any Delegation of Authority Policy (or similar policy) that may be in effect from time to time, and (b) those otherwise assigned to the Executive by the Company’s Board of Directors (or its designee) from time to
time. As of the Effective Date, certain specific duties, responsibilities and authority that have been assigned to the Executive are described in Exhibit A attached hereto. The Executive shall report to the Company’s Board of Directors,
and shall perform his duties and responsibilities to the best of his abilities and in a diligent, trustworthy, businesslike and efficient manner and shall not engage in any other business, profession, or occupation for compensation or otherwise
which could conflict or interfere with the performance of such services either directly or indirectly without the prior written consent of the Company. The Executive’s duties hereunder shall be performed during the Company’s normal
business hours and at such additional times, without the right to additional compensation, as shall be necessary for the Executive to perform such duties. 

3. Compensation. 

(a) Base Salary. The Company shall pay the Executive an annual rate of base salary of $350,000.00 (the “Base
Salary”), which Base Salary shall be payable in regular installments in accordance with the Company’s general payroll practices and subject to customary withholding and employment taxes as required by law. The Executive shall be issued
an IRS Form W-2 in connection with the payment of such Base Salary and any other items paid to the Executive in connection with the Executive’s employment with the Company. 

(b) Equity Incentive Compensation. The Executive will be eligible to receive grants of stock options, restricted stock
units, profits interests, and other forms of equity compensation awards (time and/or performance-based, collectively the “Equity Awards”). Such Equity Awards, if any, will be made in the discretion of the Company’s Board of
Directors or other applicable governing body, or any committee thereof with delegated authority to approve such Equity Awards (as applicable, the “Governing Body”), and will be subject to the terms and conditions specified by the
Governing Body, the Company’s applicable equity plan document, the award agreement that Executive will be required to execute as a condition of any grant, and the Company’s then existing clawback policy and insider trading policy, if any.













 4. Benefits. During the Term, the Executive shall be
entitled to participate in all employee benefit plans and programs maintained by the Company, as in effect from time to time (collectively, “Employee Benefit Plans”), on a basis that is no less favorable than is provided to other
similarly situated employees of the Company, to the extent consistent with applicable law and the terms of the applicable Employee Benefit Plans. The Company reserves the right to amend or terminate any Employee Benefit Plans at any time in its sole
discretion, subject to the terms of such Employee Benefit Plan and applicable law.

incurred; (b) not affect or be affected by any other expenses that are eligible for reimbursement in any other tax year of Executive; and (c) not be subject to liquidation or exchange for any other benefit.

performance) to the Company, or any of its successors, for more than ninety (90) days, unless further time is required as a reasonable accommodation under the Americans With Disabilities Act of 1990, as amended. 

(b) Severance Benefits. If the Executive’s employment under this Agreement is terminated by the Company without
Cause, or if the Executive resigns for Good Reason, the Executive shall be entitled to receive severance benefits, subject to the terms and conditions below, through the date that is twelve (12) months after the effective date of such
termination. 
 (i) Terms of Severance Payment. The Executive shall receive (A) continued payment of the Base

 (ii) Release Agreement. The

(2) calendar years, the severance payments shall not begin to be paid until the second calendar year.

shall comply with Section 409A of the Code or an exception thereto and each provision of the Agreement shall be interpreted, to the extent possible, to comply with Section 409A or an exception thereto. Nevertheless, the Company does not
and cannot guarantee any particular tax effect or treatment of the amounts due under this Agreement. Except for the Company’s responsibility to withhold applicable income and employment taxes from compensation paid or provided to the Executive,
the Company shall not be responsible for the payment of any applicable taxes on compensation paid or provided pursuant to this Agreement. Notwithstanding any other provision of this Agreement to the contrary, neither the time nor schedule of any

shall be paid prior to the Executive’s “separation from service” as defined in Treasury Regulation Section 1.409A-1(h) (applying the default rules of Treasury Regulation Section 1.409A-1(h)).

or business reputation, practices or conduct of the Company or its subsidiaries or Affiliates, or their respective shareholders, members, directors, managers, officers, employees, sales representatives, suppliers, customers, products or services.
The Executive’s obligations under this Section 10(d) do not inhibit him from participating in or filing a charge or testifying truthfully if the Executive is called upon to do so. Nothing in this
Section 10(d) is intended to limit the Executive’s ability to exercise his rights under the National Labor Relations Act.

Section 10 are reasonable and necessary to protect the legitimate business interests of the Company, (ii) any violation by the Executive of any of his covenants contained in Section 10 would
result in irreparable injury to the Company, the exact amount of which would be difficult, if not impossible, to ascertain or estimate, and (iii) the remedies at law for any such violation would not be reasonable or adequate compensation to the
Company for such a violation. Accordingly, the Executive hereby agrees that, if the Executive (including, if applicable, any Affiliate thereof), directly or indirectly, violates any of his covenants under Section 10 then,
in addition to any other remedy which may be available to the Company at law or in equity, the Company shall be entitled to specific performance and injunctive relief against such violating party (including any Affiliate), without posting bond or
other security, and without the necessity of proving actual or threatened damage or harm. 
 (g) Extension of Time for
Breach. If the Executive shall be in breach of any of the provisions of Section 10 above, then the time periods set forth in such clauses shall be extended by the length of time during which the Executive is in breach
of any of such provisions.

 (h) Reasonableness of Covenants. The Executive represents and
warrants to the Company that the covenants contained herein are reasonable, that valid consideration has or shall be received therefor, and that his experience and capabilities are such that the provisions of this
Section 10 shall not prevent him from earning an adequate livelihood. 
 (i) Cessation of
Payments. Without limiting the Company or its Affiliates’ rights and remedies hereunder, at law or in equity, it is acknowledged and agreed by the Executive that the right of the Executive to receive and retain any payments otherwise due to
him under this Agreement shall be suspended and cancelled if, and for so long as, he shall be in breach of any provision of this Section 10. If, and when, the Executive shall have cured any such breach such right shall

they will first utilize the procedures specified in Sections 14(f)(i)-(xii) (the “Procedure”) prior to commencing any action or proceeding in any court; provided, however, that such procedures shall not apply to, and the
Company may immediately commence an action or proceeding in any federal or state court located in Phoenix, Arizona (including, without limitation to seek equitable relief pursuant to Section 10(f)), in the event that the
Executive breaches any provision of Sections 10 or 11.

 (ii) The party seeking to initiate the Procedure shall give written notice
to the other party, describing in general terms the nature of the Dispute, the initiating party’s claim for relief and identifying one or more individuals with authority to settle the Dispute on such party’s behalf. The party receiving
such notice shall have three (3) business days within which to designate by written notice to the initiating party, one or more individuals with the authority to settle the Dispute on such party’s behalf. The individuals so designated
shall be known as the “Authorized Individuals.” 
 (iii) The Authorized Individuals shall be entitled to
make such investigation of the Dispute as they deem appropriate, but agree to promptly, and in no event later than five (5) business days from the date of the initiating party’s written notice, meet (in person, or via conference call or
videoconference) to discuss resolution of the Dispute. The Authorized Individuals shall meet at such times and places and with such frequency as they may agree. If the Dispute has not been resolved within ten (10) calendar days from the date of
their initial meeting, the parties shall cease direct negotiations and shall submit the Dispute to non-binding mediation in accordance with the procedure set forth below. 

(iv) The Authorized Individuals shall have three (3) business days from the date they cease direct negotiations to
submit to each other a written list of acceptable qualified attorney-mediators not affiliated with either of the parties. Within one (1) business day from the date for receipt of such list, the Authorized Individuals shall rank the mediators in
numerical order of preference and exchange such rankings. If no mediator has been selected by this procedure, within two (2) business days after the date of receipt of the list referred to in the first sentence of this
Section 14(f)(iv), the Authorized Individuals shall initiate mediation in accordance with the rules and procedures of the American Arbitration Association. 

(v) In consultation with the mediator selected, the Authorized Individuals shall promptly designate a mutually convenient
date for the mediation, which shall take place in Phoenix, Arizona, and unless circumstances require otherwise, such time to be not later than fourteen (14) calendar days after selection of the mediator. 

(vi) In the event either party has substantial need for information in the possession of the other party in order to prepare
for the mediation, the parties shall attempt in good faith to agree to procedures for the expeditious exchange of such information, with the help of the mediator if required. 

(vii) At least three (3) calendar days prior to the first scheduled session of the mediation, each party shall deliver
to the mediator and to the other party concise written summary of its views on the matter in Dispute and such other matters required by the mediator. The mediator may also request that a confidential issue paper be submitted by each party to him.

 (viii) In the mediation, each party shall be represented by an Authorized Individual and may be represented by counsel.
In addition, each party may, with permission of the mediator, bring such additional persons as needed to respond to questions, contribute information, and participate in the negotiations. 

(ix) The mediator shall determine the format for the meetings, designed to assure that both the mediator and the Authorized
Individuals have an opportunity to hear an oral presentation of each party’s views on the matter in dispute, and that the authorized parties attempt to negotiate a resolution of the matter in dispute, with or without the assistance of counsel
or others, but with the assistance of the mediator. To this end, the mediator is authorized to conduct both joint meetings and separate private caucuses with the parties. The mediation session shall be private. The mediator will keep confidential
all information learned in private caucus with any party unless specifically authorized by such party to make disclosure of the information to the other party. The parties commit to participate in the proceedings in good faith with the intention of
resolving the Dispute if at all possible.

 (x) The parties agree to participate in the mediation procedure to its
conclusion. The mediation shall be terminated (A) by the execution of a settlement agreement by the parties, (B) by a declaration of the mediator that the mediation is terminated, or (C) by a written declaration of a party to the
effect that the mediation process is terminated at the conclusion of one (1) full day’s mediation session. 

(xi) The fees and expenses of the mediator shall be shared equally by the Disputing Members. The mediator shall be
disqualified as a witness, consultant, expert or counsel for any Disputing Member with respect to the Dispute of any related matters. 

(xii) Mediation is a compromise negotiation for purposes of federal and state Rules of Evidence and constitutes privileged
communication under Delaware law. The entire mediation process is confidential, and no stenographic, visual or audio record shall be made. All conduct, statements, promises, offers, views and opinions, whether oral or written, made in the course of
the mediation by any party, their agents, employees, representatives or other invitees and by the mediator are confidential and shall, in addition and when appropriate, be deemed privileged. Such conduct, statements, promises, offers, views and
opinions shall not be discoverable or admissible for any purpose, including impeachment, in any litigation or other proceeding involving the parties, and shall not be disclosed to anyone not an agent, employee, expert, witness, or representative of
either of the parties; provided, however, that evidence otherwise discoverable or admissible is not excluded from discovery or admission as a result of its use in the mediation. 

(xiii) If the Dispute has not been resolved pursuant to the Procedure, then either party may commence an action or proceeding
in any federal or state court located in Phoenix, Arizona. The parties irrevocably submit to the exclusive jurisdiction of the federal and state courts located in Phoenix, Arizona for the purposes of any action or proceeding arising out of or
relating to this Agreement. Each party hereby consents to the personal jurisdiction of, and agrees that venue shall lie in, the state or federal courts in Phoenix, Arizona with respect to any claim or cause of action arising under or relating to
this Agreement. Each party hereby waives any objection based on forum non conveniens and waives any objection to venue of any action instituted hereunder. If any legal action or any arbitration or other proceeding is brought in connection
with this Agreement, except as set forth in Section 14(f)(xi) above, the prevailing party shall be entitled to recover reasonable attorneys’ fees, accounting fees, and other costs incurred in that action or proceeding,
in addition to any other relief to which it may be entitled.
