For those holders of Outstanding Warrants who chose not to participate in the Incentive Program, the Outstanding Warrants will remain outstanding and continue to be exercisable for Common Shares on their current terms, until March 16, 2026 at which time any Outstanding Warrants that remain unexercised will expire and be cancelled pursuant to their terms.
