As previously disclosed, subject to the terms of the MBI Term Loan Exchange Offer, any MBI Lender that delivers a lender acceptance to the designated exchange agent after 3:00 p.m. (New York City time) on June 22, 2026 will receive, in exchange for its MBI Term Loans, on a first-come first-served basis, (1) if, and solely to the extent that, the aggregate principal amount of MBI Term Loans of such participating MBI Lender, together with all MBI Term Loans of all earlier participating MBI Lenders, does not exceed 50.01% of the outstanding principal amount of MBI Term Loans, a combination of (i) 50.0% of the aggregate principal amount of the MBI Term Loans of such participating MBI Lender in cash and (ii) 50.0% of the aggregate principal amount of the MBI Term Loans of such participating MBI Lender in new first lien “first out” term loans of the Company; and/or (2) otherwise, 100% of the aggregate principal amount of the MBI Term Loans of such participating MBI Lender in new first lien “second out” term loans of the Company.

The MBI Term Loan Exchange Offer is scheduled to expire at 5:00 p.m., New York City time, on June 23, 2026, unless extended or earlier terminated by the Company in accordance with the terms of the Offer Notice (as defined below).

The Company is making the MBI Term Loan Exchange Offer pursuant to the offer materials distributed to eligible MBI Lenders.
