Agreement between Registrant and Jack Phillips, dated as of January 31, 2020

Your principal place of employment will be the Company’s principal executive offices in Tucson, Arizona.

Beginning on the Start Date, you will serve as the President and Chief Executive Officer of the Company. In your capacity as the President and Chief Executive Officer, you will have control over, and responsibility for the overall management of the Company and its subsidiaries, and you will report to the Company’s board of directors (the “Board”).

So long as you are employed as Chief Executive Officer, the Company will use its reasonable efforts, subject to applicable law and the rules of the Nasdaq Stock Market (“Nasdaq”) and the Company’s bylaws, to cause you to be nominated for election to the Board at the Company’s annual shareholder meeting (and for future years, re-election) as a director of the Company.

$595,000 per year (the “Base Salary”) to be paid according to the Company’s normal payroll cycle. Your Base Salary will be reviewed at least annually and may be adjusted upward or downward by the Compensation Committee of the Board of Directors (the “Compensation Committee”) in its sole discretion.

On the Start Date, you will be granted 50,000 Restricted Stock Units under our 2012 Omnibus Equity Incentive Plan, as amended (the “Equity Plan”). The Grant will be subject to a 5-year annual vesting schedule with the first annual vesting and issuance

Beginning January 1, 2020 and for each full calendar year during the Term thereafter, you will be eligible to participate in an annual incentive program adopted in writing and approved by the Compensation Committee (the “AIP”). Your target incentive under the AIP will equal 100% of your Base Salary as of the first day of the calendar year, with the opportunity to earn up to (but not exceed) 150% of your Base Salary as of the first day of the calendar year. Whether you are entitled to receive an AIP payment, and the amount and form of such payment, will depend on the attainment of written quantitative and qualitative performance goals, including financial performance goals, establish by the Compensation Committee in its sole discretion. The amount and form of the AIP, if any, will be certified by the Compensation Committee in February of the year following the year to which the AIP relates, and the earned AIP, if any, will be paid to you no later than March 15 of the year following the year to which the AIP relates (e.g., the AIP for 2020, if any, will be paid no later than March 15, 2021). Except as set forth below, you must be employed by the Company through the date the AIP is paid in order to earn and be eligible to receive the AIP.

Beginning January 1, 2021 and for each full calendar year during the Term thereafter, you will be eligible to receive grants of stock options, performance shares and other awards under the Equity Plan (the “Equity Awards”). The amount of Equity Awards, the mix of Equity Awards, the vesting schedule and the other terms and conditions of the Equity Awards will be established by the Compensation Committee in its sole discretion, provided, that, for the 2021 calendar year your target Equity Award grant will equal 400% of your then Base Salary and will consist of an award mix of 50% non-qualified stock options and 50% performance shares. The Equity Awards will be subject to such other terms and conditions specified by the Compensation Committee, the Equity Plan, the award agreement that you must execute as a condition of the grant(s), and the Company’s insider trading policy.

You will continue to be eligible to participate in the Company’s standard company benefit plans, as such plans may be amended, modified, or terminated by the Company from time to time, with or without notice, in accordance with the applicable benefit and vacation plan documents. For the avoidance of doubt, your participation in such plans will be subject to the terms and conditions set forth in the applicable benefit plan documents.

The initial term of your employment under this Agreement shall commence on the Start Date and shall continue until the two (2) year anniversary of the Start Date (the “Initial Term”). The Initial term will automatically extend on the same terms and conditions set forth below for additional one (1) year periods (each a “Renewal Term”), unless either party gives the other party written notice of non-renewal at least 30 days prior to the end of the Initial Term or any Renewal Term. The Initial Term, together with all Renewal Terms, are collectively referred to in this Agreement as the “Term.”

This Agreement, and your employment hereunder, may be terminated at any time, for any reason, by you or the Company upon at least 30 days prior written notice, provided, that, the Company may terminate your employment immediately for Cause. Upon your termination for any reason, the Company will pay you your accrued but unpaid Base Salary and any accrued but unpaid reasonable business expenses through your date of termination (the “Accrued Obligations”), with such amount paid in compliance in accordance with applicable law. In addition to the Accrued Obligations, you may be entitled to receive severance benefits and Equity Award acceleration as described below.

This Agreement, and your employment hereunder, will terminate immediately upon your death or Disability (as defined in Exhibit A). In such case, you (or your spouse or estate) will be entitled to the Accrued Obligations.

In the event your employment is terminated by the Company without Cause or by you with Good Reason (as defined in Exhibit A) prior to a Change of Control (as defined in Exhibit A), then, in addition to the Accrued Obligations, and subject to your timely execution (and non-revocation) of the release described below, you will be entitled to receive a cash severance payment equal to the sum of: (i) 12 months of your then Base Salary; and (ii) your average earned AIP for over the Term (collectively, the “Base Severance Amount”). The Base Severance Amount will be paid to you in installments over a 12 month period, in accordance with the Company’s normal payroll cycle, with the first installment paid during the first payroll period following the expiration of the release revocation period described below. In addition to the Base Severance Amount, you will be entitled to receive a pro-rata AIP for the year in which your termination occurred, with such pro-rata AIP paid at the same time described above.

Upon the closing of a transaction that results in a Change of Control, and notwithstanding anything in the Equity Plan to the contrary, your Option and other Equity Awards shall fully vest and become exercisable.

In the event your employment is terminated by the Company without Cause or by you with Good Reason (as defined in Exhibit A) during the 12 month period following a Change of Control, then, in addition to the Accrued Obligations, and subject to your timely execution (and non-revocation) of the release described below, you will be entitled receive a cash severance payment equal to the sum of: (i) 18 months of your then Base Salary; and (ii) 18 times the monthly amount that is charged to COBRA qualified beneficiaries for the same medical coverage options elected by you immediately prior to your last day of employment (collectively, the “Enhanced Severance Amount”). The Enhanced Severance Amount will be paid to you in installments over a 18 month period, in accordance with the Company’s normal payroll cycle, with the first installment paid during the first payroll period following the expiration of the release revocation period described below. In addition to the Enhanced Severance Amount, you will be entitled to receive a pro-rata AIP for the year in which your termination occurred, with such pro-rata AIP paid at the same time described above.

In order to receive the severance pay and other benefits described above, you must, no later than 60 days following your last day of employment, execute (and not revoke) a general release and waiver of any claims that you may have in connection with your employment and termination of employment with the Company and its affiliates.

This offer is contingent upon you, on your Start Date, signing the Restrictive Covenant Agreement attached hereto as Exhibit B.

Following the termination of your service with the Company for any reason, you agree to cooperate fully with the Company and with the Company’s counsel in connection with any present and future actual or threatened litigation, administrative proceeding or other investigation involving the Company or any affiliate that relates to events, occurrences or conduct occurring (or claimed to have occurred) during your employment.

During the Term and following the termination of your service for any reason, you agree that you will not criticize, defame, be derogatory toward or otherwise disparage the Company, its products, services, or the Company’s past, present and future officers, directors, managers, stockholders, agents, representatives, employees, or affiliates, or its or their business plans or actions, to any third-party, either orally or in writing; provided that that this provision will not preclude you from giving truthful testimony in response to a lawful subpoena or preclude any conduct protected under any local, state or federal law, including those providing “whistleblower” protection to you or the right to engage in concerted activities. Finally, on the date of your termination of service for any reason, you agree to update your profile on social media websites (such as LinkedIn) to reflect that you are no longer an employee of the Company.

To the extent required by law, the Company shall withhold from any payments due to you under this Agreement any applicable federal, state or local taxes. You hereby acknowledge that neither the Company nor any of its affiliates, shareholders, members, directors, managers, officers, employees, agents or representatives have provided you with any tax-related advice with respect to the matters covered by this Agreement and that you are solely responsible for obtaining your own tax advice with respect to the matters covered by this Agreement.

Notwithstanding anything in this Agreement to the contrary, if the Company concludes, that the Base Severance Amount or the Enhanced Severance Amount are subject to Section 409A of the Internal Revenue Code, then no such Severance Amount will be paid prior to your “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)). Installment payments made pursuant to this Agreement shall be treated as separate payments for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii).
