“Ticking Fee Start Date” means November 1, 2023; provided that if initial filing of the Proxy Statement is filed with the SEC after July 5, 2023, then the Ticking Fee Start Date shall be delayed by the number of calendar days that have elapsed after July 5, 2023 through the date the initial filing of the Proxy Statement is filed with the SEC.
