Payment and Paying Agents

We will pay interest on any debt securities to the person in whose name the debt securities are registered on the regular record date for the
applicable interest payment date. (sections 2.03 and 3.03)

We will pay principal, any premium and interest on the debt securities of a
particular series at the office of one or more paying agents that we designate for that series. Unless otherwise stated in the applicable officers’ certificate, supplemental indenture and prospectus supplement, we will initially designate the
corporate trust office of the trustee in the City of New York as our sole paying agent. We will be required to maintain a paying agent in each place of payment for the debt securities. (sections 4.01, 4.02 and 4.03)

All money we pay to a paying agent or the trustee for the payment of principal, any premium or interest on any debt security which remains
unclaimed for a period of two years after the principal, premium or interest has become due and payable will, upon our request, be repaid to us, and the holder of the debt security may then look only to us for payment of those amounts. (section
11.05)

Governing Law

The indenture
and the debt securities will be governed by and interpreted in accordance with the laws of the State of New York. (section 13.05)
