The PSUs shall vest, if at all, based on the 60-Day VWAP in accordance with the schedule below:

As used herein, the “60-Day VWAP” means the volume-weighted average price of a Share for the 60 consecutive trading days immediately preceding October 17, 2025 (such period, the “Performance Period”), as adjusted for stock splits, stock dividends and other similar events.
