 25,
2025, and ending on (and including) December 25, 2028, with respect to the floating rate notes (each a “Floating Rate Interest Reset Date”); provided that if any Floating Rate Interest Reset Date would fall on a day that is not
a Business Day, such Floating Rate Interest Reset Date will be postponed to the next succeeding Business Day. If the next succeeding Business Day falls in the next calendar month, however, then the relevant Floating Rate Interest Reset Date shall be
brought forward to the immediately preceding day that is a Business Day.

The Calculation Agent for the notes is The Bank of New York
Mellon or its successor appointed by the Issuer. The Calculation Agent will determine the Floating Interest Rate for each Floating Rate Interest Period for the notes by reference to the SOFR Index Average on the applicable Floating Rate Interest
Determination Date. Promptly upon such determination, the Calculation Agent will notify the Issuer and the trustee (if the Calculation Agent is not the trustee) of the applicable Floating Interest Rate. Upon the request of the holder of any note,
the Calculation Agent will provide the Floating Interest Rate as determined for the most recent applicable Floating Rate Interest Period.

Subject to the circumstances described under “—SOFR Discontinuation” below, the “SOFR Index Average”
for each Floating Rate Interest Period shall be equal to the value of the SOFR rates for each day during the relevant Floating Rate Interest Period as calculated by the Calculation Agent as follows:

with the resulting percentage being rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, with 0.000005 being rounded upwards, where:

“dc” for any SOFR Observation Period, means the number of
calendar days in the relevant SOFR Observation Period;

“SOFR Index” means the SOFR Index in relation to any U.S.
Government Securities Business Day as published by the NY Federal Reserve on the NY Federal Reserve’s Website at the SOFR Determination Time;

S-27

“SOFR IndexEnd” means the SOFR Index value on the date that is two U.S. Government Securities Business Days preceding the Floating Rate Interest Payment Date relating to such Floating
Rate Interest Period (or in the final Floating Rate Interest Period, preceding the Maturity Date) (such date a “SOFR Index Determination Date”); and

“SOFR IndexStart” means the SOFR Index value on the date that
is two U.S. Government Securities Business Days preceding the first date
