. If we exercise our defeasance option, payment of the securities may not be accelerated by the reference to restrictive covenants which are subject to covenant defeasance. If we do not comply with our remaining obligations after exercising our covenant defeasance option and the securities are declared due and payable because of the occurrence of any event of 9

default, the amount of money and U.S. Government obligations on deposit in the defeasance trust may be insufficient to pay amounts due on the securities at the time of the acceleration. However,
we will remain liable for those payments. (Sections 1302, 1303 and 1304)

Changes to the Indenture

Holders who own more than a majority in principal amount of the outstanding debt securities of a series can agree with us to change the
provisions of the indenture relating to that series. However, no change can affect the payment terms or the percentage required to change certain other terms without the consent of all holders of debt securities of the affected series. (Section 902)

We and the trustee may enter into supplemental indentures for other specified purposes and to make changes that would not
materially adversely affect the interests of the holders of debt securities issued under the indenture, including the creation of any new series of debt securities, without the consent of all affected holders of those debt securities. (Section 901)

Governing Law

New York law will govern the indenture and the debt securities. (Section 112)

Trustee

The Bank of New
York Mellon, as successor trustee to JPMorgan Chase Bank, serves as the trustee under the indenture. If we use a different trustee for any series of debt securities, we will inform you in a prospectus supplement. In the ordinary course of its
business, The Bank of New York Mellon and its affiliates have engaged and may in the future engage in commercial and investment banking transactions with us.
