(a)Vesting. Except as otherwise provided in this Section 2, the Options shall become vested, if at all, in five equal installments on each of the first through fifth anniversaries 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. The period over which the Options vest is referred to as the “Vesting Period.”

(b)Termination of Services. Subject to the terms of any employment or Services agreement that the Participant may have with the Company or any of its Subsidiaries, if, at any time during the Vesting Period, the Participant’s Services to the Company terminate (whether initiated by the Participant or by the Company), all Options which are unvested as of the date of termination shall automatically terminate and be forfeited without payment, and the Participant shall have 90 days (180 in the case of death or Disability) following the date of termination to exercise vested Options.

(c)Committee Discretion. Notwithstanding anything contained in this Agreement to the contrary, the Committee, in its sole discretion, may accelerate the vesting with respect to any Options under this Agreement, at such times and upon such terms and conditions as the Committee shall determine.

(d)No Other Accelerated Vesting. The vesting and exercisability provisions set forth in Section 2 or expressly set forth in the Plan, shall be the exclusive vesting and exercisability provisions applicable to Options and shall supersede any other provisions relating to vesting and exercisability, unless such other provision expressly refers to the Plan by name and this Agreement by name and date..

(a)Restrictions on Transferability. The Options 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 not be treated as the record owner of the Shares underlying the Options until the underlying Shares are delivered in settlement thereof, at which time the Participant 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.

(a)Binding Effect; Benefits. This Agreement shall be binding upon and inure to the benefit of the parties to this Agreement and their respective successors and assigns. Nothing in this Agreement, express or implied, is intended or shall be construed to give any person other than the parties to this Agreement or their respective successors or assigns any legal or equitable right, remedy or claim under or in respect of any agreement or any provision contained herein.

(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 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 Options or the underlying 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 upon exercise of settlement of the Options 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 such exercise. 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)Forfeiture, Cancellation and “Clawback” of Awards. The Participant shall forfeit and disgorge to the Company any Options 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. The implementation of policies and procedures pursuant to this Section 7(e) and any modification of the same shall not be subject to any restrictions on amendment or modification of Awards. Awards granted under the Plan (and gains earned or accrued in connection with Awards) shall also be subject to such generally applicable policies as to forfeiture and recoupment (including, without limitation, upon the occurrence of material financial or accounting errors, financial or other misconduct or Competitive Activity) as may be adopted by the Administrator or the Board from time to time and communicated 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.

(f)Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York regardless of the application of rules of conflict of law that would apply the laws of any other jurisdiction.
