one with a maturity date following such date, the Issuer shall select the United States Treasury security with a maturity date preceding such date. If there are two or more United States Treasury
securities maturing on the Par Call Date or, in the case of the 2027 Fixed Rate Notes, the maturity date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or
more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining
the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal
amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Remaining
Scheduled Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date for such redemption (assuming, for this
purpose, that the Notes matured on November 3, 2027 for the 2027 fixed rate notes, on November 3, 2028 for the 2028 fixed rate notes and on November 3, 2032 for the 2032 fixed rate notes).

The notice of redemption will state any conditions applicable to a redemption and the amount of Notes to be redeemed. If less than all the
Notes are to be redeemed, the Notes to be redeemed will be selected on a pro rata basis or, as long as the Notes are in the form of global securities, in accordance with DTC’s procedures.

The Issuer’s and any of its designees’ (including the Trustee acting in its capacity of Calculation Agent) actions and
determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any
redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the procedures of the Trustee acting in its capacity of Security Registrar) at least 10 days but not more than 60 days before the redemption date to
each registered holder as of the applicable record date of the Notes of the applicable series to be redeemed by the Issuer
