 and including November 6,
2035 (the “2035 Fixed Rate Notes Maturity Date”) or any date of earlier redemption. Interest will be paid to holders of record of the 2035 Fixed Rate Notes in respect of the principal amount thereof outstanding as of the close of
business 15 calendar days preceding the relevant 2035 Fixed Interest Payment Date, whether or not a Business Day.

Interest on the 2035
Fixed Rate Notes will be calculated on the basis of a 360-day year consisting of twelve 30-day months and, in the case of an incomplete month, on the basis of the actual
number of days elapsed in such month. If any scheduled 2035 Fixed Interest Payment Date is not a Business Day, we will pay interest on the next Business Day, but interest on that payment will not accrue during the period from and after the scheduled
2035 Fixed Interest Payment Date. If the 2035 Fixed Rate Notes Maturity Date or date of redemption or repayment is not a Business Day, we may pay interest and principal on the next succeeding Business Day, but interest on that payment will not
accrue during the period from and after the 2035 Fixed Rate Notes Maturity Date or date of redemption or repayment.

General

The Notes will constitute three separate series of senior non preferred debt securities issued pursuant to the provisions of an indenture dated
as of March 14, 2024 (as heretofore amended and supplemented, the “Base Indenture”) between us as Issuer and The Bank of New York Mellon, London Branch, as trustee (the “Trustee”), as amended and supplemented by a third
supplemental indenture to be dated as of the date of issuance of the Notes (the “Third Supplemental Indenture”) between us as Issuer and the Trustee.

Book-entry interests in the Notes will be issued in denominations of $200,000 and integral multiples of $200,000 in excess thereof.

With respect to the Notes, the term “Business Day” means any day, other than Saturday or Sunday, that is not a legal holiday nor a
day on which banking institutions are authorized or required by law, regulation or executive order to close in the City of New York or London nor a day when the T2 real-time gross settlement (RTGS) system, owned and operated by the Eurosystem, or
any successor thereto, is closed for business.
