(1)                A series of debt securities is hereby established under the Indenture, and such series of debt securities shall be known and designated as the “3.250% Notes due 2031” (the “Securities”).

(2)                The aggregate principal amount of the Securities of such series which may be authenticated and delivered under the Indenture is limited to $600,000,000, except for Securities of such series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of such series pursuant to Sections 304, 305, 306, 906 or 1107 of the Indenture; provided, however, that such series of Securities may be re-opened by the Company for the issuance of additional Securities of such series, so long as any such additional Securities of such series have the same form and terms (other than, if applicable, the offering price, underwriting or other discounts and commissions, the original date of issuance, the first date on which interest thereon shall be payable and the date from which interest thereon shall begin to accrue), and carry the same right to receive accrued and unpaid interest, as the Securities of such series theretofore issued; provided, however, that, notwithstanding the foregoing, such series of Securities may not be reopened if the Company has effected defeasance or covenant defeasance with respect to the Securities of such series pursuant to Section 1402 and 1403, respectively, of the Indenture or has effected satisfaction and discharge with respect to the Securities of such series pursuant to Section 401 of the Indenture.

Notwithstanding the foregoing, certificated Securities of such series in definitive form (“Certificated Securities”) may be issued in exchange for Global Securities of such series under the circumstances contemplated by Section 305 of the Indenture.

(4)                The Securities of such series shall be sold by the Company to the several underwriters named in the Purchase Agreement dated May 6, 2020, for whom Citigroup Global Markets Inc., BofA Securities, Inc., Barclays Capital Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC are acting as representatives, at a price equal to 98.337% of the principal amount thereof.

Interest on the Securities will be computed on the basis of a 360-day year of twelve 30-day months. If any principal of, or premium, if any, or interest on, any of the Securities of such series is not paid when due, then such overdue principal and, to the extent permitted by law, such overdue premium or interest, as the case may be, shall bear interest until paid or until such payment is duly provided for at the rate of 3.250% per annum.
