“provided that, in the event the Termination Date is on or after July 1, 2024, (A) such amount shall equal 100% (instead of 50%) of the Executive’s Base Salary, which shall be paid in equal periodic installments over a period of twelve (12) months following the Termination Date (instead of six (6) months) in accordance with the Company’s customary payroll practices and (B) each stock option granted to the Executive under the Company’s (or any parent’s or affiliate’s) equity plan, other than the stock option under grant number 0039 (which grant shall not be subject to this subsection (B)), that is outstanding and exercisable as of the Termination Date (each, an “Option”) shall remain outstanding for a period of 180 days following the Termination Date (or such longer period so that there is at least a 30-day open trading window during such period), but in no event later than expiration of the Option term (the “Extended Post Termination Exercise Period”), during which time the Option will be exercisable for the number of shares that were vested as of the Termination Date;”
