Notwithstanding the Early Settlement Date, Eligible Holders (as defined below) who did not tender at or prior to the Early Participation Deadline may still tender Existing Masonite Notes in the Exchange Offer until 5:00 p.m., New York City time, on May 30, 2024, unless such date is extended or the Exchange Offer and Consent Solicitation are earlier terminated (such date and time, as the same may be extended, the “Expiration Time”).
