(a)Vesting. Except as otherwise provided in this Section 2, the Restricted Shares shall become vested, if at all, in five equal installments on each anniversary of the grant date set forth in the Notice of Grant (the “Grant Date”), subject to the Participant’s continued provision of Services to the Company or any Subsidiary thereof through such date.

For purposes of this Agreement, each of “Good Reason”, “Cause” and “Non-Renewal Notice” shall have the meaning set forth in the Employment Agreement.

(ii)Death; Disability. If, at any time during the Restricted Period, the Participant’s Services to the Company terminate by reason of the Participant’s death or Disability, a number of Restricted Shares shall vest as of the date of the Participant’s Termination of Service equal to the number of Restricted Shares that would have vested had the Participant’s Service continued through the next vesting date immediately following the date of the Participant’s Termination of Services.

3.Securities Law Compliance. Notwithstanding any other provision of this Agreement, the Participant may not sell the Restricted Shares that become vested unless such Shares are registered under the Securities Act of 1933, as amended (the “Securities Act”), or, if such Shares are not then so registered, such sale would be exempt from the registration requirements of the Securities Act. The sale of such Shares must also comply with other applicable laws and regulations governing the Shares and Participant may not sell the Shares if the Company determines that such sale would not be in material compliance with such laws and regulations.

4.Participant’s Rights with Respect to the Restricted Shares.

(a)Restrictions on Transferability. During the Restricted Period, the Restricted Shares granted hereby are not assignable or transferable, in whole or in part, and may not, directly or indirectly, be offered, transferred, sold, pledged, assigned,

alienated, hypothecated or otherwise disposed of or encumbered (including without limitation by gift, operation of law or otherwise) other than by will or by the laws of descent and distribution to the estate of the Participant upon the Participant’s death.

(b)Rights as Shareholder; Dividends. The Participant shall be the record owner of the Restricted Shares until the Shares are sold or otherwise disposed of, and shall be entitled to all of the rights of a shareholder of the Company including, without limitation, the right to vote such shares and receive all dividends or other distributions paid with respect to such shares. Notwithstanding the foregoing, any non-cash dividends or other distributions shall be subject to the same restrictions on transferability as the Restricted Shares with respect to which they were paid. If the Participant forfeits any rights he has under this Agreement in accordance with Section 2, the Participant shall, on the date of such forfeiture, no longer have any rights as a shareholder with respect to the Restricted Shares and shall no longer be entitled to vote or receive dividends on such Shares.

(c)Shares Certificates. The Company may issue shares certificates or evidence the Participant’s interest by using a restricted book entry account with the Company’s transfer agent. Physical possession or custody of any shares certificates that are issued shall be retained by the Company until such time as the Restricted Shares vest.

5.Adjustment in Capitalization.

6.Miscellaneous.

(b)No Right to Continued Services. Nothing in the Plan or this Agreement shall interfere with or limit in any way the right of the Company or any of its Subsidiaries or Shareholders to terminate the Participant’s Services at any time, or confer upon the Participant any right to continue in the Services of the Company or any of its Subsidiaries.

(c)Interpretation. The Committee shall have full power and discretion to construe and interpret the Plan (and any rules and regulations issued thereunder) and this Award. Any determination or interpretation by the Committee under or pursuant to the

Plan or this Award shall be final and binding and conclusive on all persons affected hereby.

(d)Tax Withholding. The Company and its Subsidiaries shall have the right to deduct from all amounts paid to the Participant in cash (whether under the Plan or otherwise) any amount of taxes required by law to be withheld in respect of the Restricted Shares under the Plan as may be necessary in the opinion of the Company to satisfy tax withholding required under the laws of any country, state, city or other jurisdiction, including but not limited to income taxes, capital gains taxes, transfer taxes, and social security contributions that are required by law to be withheld. The Company may require the recipient of the Shares to remit to the Company an amount in cash sufficient to satisfy the amount of taxes required to be withheld as a condition to the issuance of shares deliverable to the Participant upon vesting of the Restricted Shares. The Committee may, in its discretion, require the Participant, or permit the Participant to elect, subject to such conditions as the Committee shall impose, to meet such obligations by having the Company sell the least number of whole Shares having a Fair Market Value sufficient to satisfy all or part of the amount required to be withheld. The Company may defer delivery of the Shares until such requirements are satisfied.

(e)Section 83(b) Election. The Participant may make an election under Code Section 83(b) (a “Section 83(b) Election”) with respect to the Restricted Shares.

The Participant agrees to assume full responsibility for ensuring that the Section 83(b) Election is actually and timely filed with the US Internal Revenue Service and for all tax consequences resulting from the Section 83(b) Election.

(f)Forfeiture, Cancellation and “Clawback” of Awards. The Participant shall forfeit and disgorge to the Company any Restricted Shares granted or vested and any gains earned or accrued due to the sale of any Shares to the extent required by the Company’s Executive Compensation Clawback Policy, as adopted on February 27, 2018 and as the same may be amended from time to time, or Applicable Law or regulations in effect on or after the Effective Date, including Section 304 of the U.S. Sarbanes-Oxley Act of 2002 and Section 10D of the Exchange Act. For the avoidance of doubt, the Committee shall have full authority to implement any policies and procedures necessary to comply with Section 10D of the Exchange Act and any rules promulgated thereunder.

to Participants. Any such policies may (in the discretion of the Administrator or the Board) be applied to outstanding Awards at the time of adoption of such policies, or on a prospective basis only.
