Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on January 19, 2022 (the “Final Exercise Date”).
It is intended that the option evidenced by this agreement shall not be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”). Except as otherwise indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms.
This option will become exercisable (“vest”) as to the entire original number of Shares on the Vesting Commencement Date (as defined below). For purposes of this Agreement, “Vesting Commencement Date” shall mean January 19, 2017.
The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan.
