4. ELIGIBILITY AND PARTICIPATION. Participation in the Plan shall be limited to those employees of the Company or its subsidiaries selected by the Committee from time to time in its sole discretion, and no person shall be entitled to any Award for a Performance Period unless the individual is designated as a Participant for the Performance Period. The Committee may add to or delete individuals from the list of designated Participants at any time and from time to time, in its sole discretion. No Participant who is granted an Award under the Plan shall have any right to a grant of future Awards under the Plan. By accepting any payment under the Plan, each Participant and each person claiming under or through such Participant shall be conclusively deemed to have indicated such person’s acceptance and ratification of, and consent to, any action taken under the Plan by the Company or the Committee. Subject to the terms and conditions of the Plan, determinations made by the Committee under the Plan need not be uniform and may be made selectively among eligible employees under the Plan, whether or not such employees are similarly situated.

5. GRANT OF AWARDS; PAYMENT OF AWARDS.

(a) AWARDS. The Committee shall establish the terms and conditions applicable to any Award granted under the Plan and a Participant shall be eligible to receive an Award under the Plan in accordance with such terms and conditions. Without limiting the foregoing, the Committee may grant Awards subject to any or all of the following: (i) attainment of time-based vesting conditions; (ii) attainment of any Performance Goal established by the Committee with respect to any Performance Period; or (iii) the Committee’s evaluation of a Participant’s individual performance for the Company and/or its subsidiaries. The Committee may, in its sole discretion, amend or modify the terms and conditions applicable to an Award (provided that the consent of an affected Participant shall be required prior to any amendment or modification that adversely affects a Participant’s outstanding Awards) and may elect to pay all or any portion of an Award to a Participant regardless of whether any Award is payable in accordance with the terms and conditions originally established by the Committee, subject to the limitations of Section 6 hereof.

(b) TIME OF PAYMENT. Unless otherwise determined by the Committee, Awards shall be paid in the calendar year following the year to which such Award relates at such time or times as determined by the Committee in its sole discretion. Notwithstanding the foregoing, the Committee may defer payment of all or any portion of any Awards with such conditions as the Committee may determine and may permit a Participant electively to defer receipt of all or a portion of an Award, in each case, taking into account the requirements of Section 409A.

(c) FORM OF PAYMENT. In the sole discretion of the Committee, Awards may be paid in whole or in part in cash, Common Stock or other property, provided that any Common Stock to be awarded as part of an Award hereunder shall be issued pursuant to the terms and conditions of any shareholder-approved equity plan of the Company (if any) as in effect from time to time. To the extent that there is no shareholder-approved equity plan of the Company with an available share reserve to cover the issuance of Common Stock in connection with the payment of any Award hereunder, the full amount of the Award shall be paid in cash.

(d) IMPACT OF TERMINATION OF EMPLOYMENT. Unless otherwise determined by the Committee in its sole discretion, the right to any payment in respect of an Award hereunder shall be subject to the Participant’s continued employment with the Company or its subsidiaries on the applicable date of payment of the Award.

6. SECTION 162(m) COMPLIANCE. Notwithstanding any other provision of the Plan to the contrary, the provisions of this Section 6 shall apply to the extent that an Award under the Plan is intended to be a Section 162(m) Award.

(a) GRANT TIMING. For purposes of any Award payable hereunder that is intended to be a Section 162(m) Award, the Committee shall make such determinations with respect to such Award and shall establish the objective performance criteria and the individual target Award (if any) applicable to each Participant or class of Participants in writing within ninety (90) days after the beginning of the applicable Performance Period (or such other time period as is required under Section 162(m)) and while the outcome of the Performance Goals is substantially uncertain. The applicable performance criteria shall be based on one or more of the Performance Goals set forth in Schedule A hereto.

(b) OBJECTIVE CRITERIA. Subject to the limitations of the Plan, the Committee shall, in its sole discretion, have authority to determine the eligible Participants to whom, and the time or times at which, Section 162(m) Awards shall be made, the vesting and payment provisions applicable to such Awards, and all other terms and conditions of such Awards. As and to the extent required by Section 162(m), the terms of an Award that is a Section 162(M) Award must state, in terms of an objective formula or standard, the method of computing the amount of compensation payable under the Award, and must preclude discretion to increase the amount of compensation payable under the terms of the Award (but may allow the Committee discretion to decrease the amount of compensation payable).

(c) OTHER TERMS. For each Participant, the Committee may specify a target Award. The individual target Award may be expressed, at the Committee’s discretion, as a fixed dollar amount, a percentage of base salary, or an amount determined pursuant to an objective formula or standard. Establishment of an individual target Award for a Participant for a Performance Period shall not imply or require that the same level individual target Award (if any such Award is established by the Committee for the relevant Participant) be set for any subsequent Performance Period. At the time the Performance Goals are established, the Committee shall prescribe a formula to determine the percentages (which may be greater than 100%) of the individual target Award, which may be payable based upon the degree of attainment of the Performance Goals during the Performance Period.

(d) MEASUREMENT OF ACHIEVEMENT. The measurements used in Performance Goals set under the Plan shall be determined in accordance with generally accepted accounting principles, except, to the extent that any objective Performance Goals are used, if any measurements require deviation from generally accepted accounting principles, such deviation shall be at the discretion of the Committee at the time the Performance Goals are set or at such later time to the extent permitted under Section 162(m).

(e) COMMITTEE CERTIFICATION. At the expiration of the applicable Performance Period, the Committee shall determine and certify in writing the extent to which the Performance Goals established pursuant to this Section 6 have been achieved and the percentage of the Participant’s individual target Award that has been vested and earned. Following the Committee’s determination and certification in accordance with the foregoing, the Section 162(m) Award shall become vested and payable in accordance with the terms and conditions of the Plan.

(f) MAXIMUM AWARD. The maximum value of any payment under any Section 162(m) Award to any Participant in the Plan with respect to any twelve (12)-month period shall be $5,000,000.

7. NON-ASSIGNABILITY. No Award or payment thereof nor any right or benefit under the Plan shall be subject to anticipation, alienation, sale, assignment, pledge, encumbrance, garnishment, execution or levy of any kind or charge, and any attempt to anticipate, alienate, sell, assign, pledge, encumber and to the extent permitted by applicable law, charge, garnish, execute upon or levy upon the same shall be void and shall not be recognized or given effect by the Company.

8. SUCCESSORS. For purposes of the Plan, the Company shall include any and all successors or assignees, whether direct or indirect, by purchase, merger, consolidation or otherwise, to all or substantially all of the business or assets of the Company and such successors and assignees shall perform the Company’s obligations under the Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession or assignment had taken place. In the event that the surviving corporation in any transaction to which the Company is a party is a subsidiary of another corporation, the ultimate parent corporation of such surviving corporation shall cause the surviving corporation to perform the obligations of the Company under the Plan in the same manner and to the same extent that the Company would be required to perform such obligations if no such succession or assignment had taken place. In such event, the term “Company,” as used in the Plan, shall mean the Company, as hereinbefore defined, and any successor or assignee (including the ultimate parent corporation) to the business or assets thereof which by reason hereof becomes bound by the terms and provisions of the Plan.

9. NO RIGHT TO EMPLOYMENT. Nothing in the Plan or in any notice of an Award shall confer upon any person the right to continue in the employment of the Company or one of its subsidiaries or affect the right of the Company or any of its subsidiaries to terminate the employment of any Participant at any time or for any reason (or no reason).

10. AMENDMENT OR TERMINATION. The Board reserves the right, subject to shareholder approval to the extent required by applicable law, regulation or exchange listing rules, to amend, suspend or terminate the Plan at any time, provided that no amendment, suspension or termination may adversely affect the rights of any

Participant with regard to any outstanding Award. In no event may any such amendment, suspension or termination result in an increase in the amount of compensation payable pursuant to any Award under the Plan or the failure of any such Award to qualify for the “performance-based compensation” exception under Section 162(m) to the extent applicable.

11. EFFECTIVE DATE AND TERM OF PLAN. The Board approved the Plan effective as of March 27, 2019, subject to shareholder approval for purposes of Awards intended to be Section 162(m) Awards. No Award under the Plan that is intended to be a Section 162(m) Award shall be granted on or after the fifth anniversary of the shareholder approval of the Plan unless the Performance Goals are re-approved (or other designated Performance Goals are approved) by the shareholders no later than the first shareholder meeting that occurs in the fifth year following the year in which shareholders approve the Performance Goals.

12. SEVERABILITY. In the event that any one or more of the provisions contained in the Plan shall, for any reason, be held to be invalid, illegal or unenforceable, in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Plan and the Plan shall be construed as if such invalid, illegal or unenforceable provisions had never been contained therein.

13. WITHHOLDING. The Company shall have the right to make such provisions as it deems necessary or appropriate to satisfy any obligations it may have under applicable law to withhold federal, state or local income or other taxes incurred by reason of the payment of Awards under the Plan.

14. GOVERNING LAW. The Plan and any amendments hereto shall be construed, administered, and governed in all respects in accordance with the laws of the State of Delaware (regardless of the law that might otherwise govern under applicable principles of conflict of laws).

15. COMPANY RECOUPMENT OF AWARDS. All Awards shall be subject to any right or obligation that the Company may have regarding the clawback of “incentive-based compensation” under Section 10D of the Securities Exchange Act of 1934, as amended (as determined by the applicable rules and regulations promulgated thereunder from time to time by the U.S. Securities and Exchange Commission).

16. SECTION 409A COMPLIANCE. The Plan is intended to either comply with, or be exempt from, the requirements of Section 409A. To the extent that the Plan is not exempt from the requirements of Section 409A, the Plan is intended to comply with the requirements of Section 409A and shall be limited, construed and interpreted in accordance with such intent. Accordingly, the Company reserves the right to amend the provisions of the Plan at any time and in any manner without the consent of Participants solely to comply with the requirements of Section 409A and to avoid the imposition of the additional tax, interest or income inclusion under Section 409A on any payment to be made hereunder while preserving, to the maximum extent possible, the intended economic result of the Award of any affected Participant. In no event whatsoever shall the Company be liable for any additional tax, interest, income inclusion or other penalty that may be imposed on a Participant by Section 409A or for damages for failing to comply with Section 409A. Notwithstanding any contrary provision in the Plan, to the extent that the payment of an Award is to be made as a result of a Participant’s “separation from service” (within the meaning of Section 409A) and such Participant is a “specified employee” (as defined under Section 409A) of the Company at the time of such “separation from service,” the payment of the Award shall be delayed for the first six (6) months following such “separation from service” (or, if earlier, the date of such Participant’s death) and shall instead be paid in the manner set forth for the applicable Award upon expiration of such delay period.

17. TITLES AND HEADINGS. The headings and titles used in the Plan are for reference purposes only and shall not affect in any way the meaning or interpretation of the Plan.
