• to amend the Second Proposed Amendment, to amend Section 6.01(1) in the Indenture (and paragraph 15(a) in the Global Securities (as defined in the Indenture) representing the Notes), solely in connection with the Additional Consent Fee Trigger (as defined below), to further extend the grace period set forth therein as it relates to the payment of interest due on the Notes on December 30, 2020 for an additional 45 days, through (and including) May 29, 2021 (as amended, the “Second Proposed Amendment” and, together with the First Proposed Amendment, the “Proposed Amendments”) and to increase the Additional Consent Fee from U.S.1.00 (the “Original Additional Consent Fee”) to U.S.1.50 per U.S.$1,000 aggregate principal amount of Notes (as amended hereby, the “Additional Consent Fee”) for which a Holder thereof has delivered valid and unrevoked Consents on or prior to the Expiration Date; and
