Statement&#148;), prospectus dated May&nbsp;4, 2015, and related prospectus supplement dated September&nbsp;14, 2016. The Company intends to use the net proceeds of the issuance to repay in full at maturity the Company&#146;s $650 million aggregate
principal amount of 2.65% notes due February 2017. The Company intends to use the balance of the net proceeds for general corporate purposes. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company entered into an underwriting agreement, dated September&nbsp;14, 2016 (the &#147;Underwriting Agreement&#148;) with Goldman,

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The 2026 Notes bear interest at a rate of 2.875%&nbsp;per annum and mature on October&nbsp;15, 2026 and the 2046 Notes bear interest at a rate
of 4.000%&nbsp;per annum and mature on October&nbsp;15, 2046. Interest on the Notes is payable semi-annually in arrears on April&nbsp;15 and October&nbsp;15 of each year, beginning on April&nbsp;15, 2017. The Notes will be redeemable at the option
of the Company in whole at any time or in part from time to time at a redemption price as described below. The redemption price for the 2026 Notes, at any time prior to July&nbsp;15, 2026 (the &#147;2026 Par Call Date&#148;), and the 2046 Notes, at
any time prior to April&nbsp;15, 2046 (the &#147;2046 Par Call Date&#148; and, together with the 2026 Par Call Date, the &#147;Par Call Dates&#148;) will be equal to the greater of (i)&nbsp;100% of the aggregate principal amount of the Notes to be

including any portion of the payments of interest accrued as of such redemption date, discounted to the redemption date; plus in each case accrued and unpaid interest. On or after each of the Par Call Dates, the redemption price will be equal to
100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to the redemption date. The Notes are general unsecured obligations and rank equally in right of payment with any of the Company&#146;s existing and

of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such

together with the Original Indenture, the &#147;Indenture&#148;), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (the &#147;Trustee,&#148; which term includes any successor trustee under the Indenture), to which
Indenture and all indentures incidental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the holders of the Senior Notes (as defined
below) issued thereunder and of the terms upon which said Senior Notes are, and are to be, authenticated and delivered. The Securities represented by this Note are one of the series designated on the face hereof as 2.875% Senior Notes due 2026 (the
&#147;Senior Notes&#148;), initially limited in aggregate principal amount to $300,000,000; provided, however, that the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the holders of the Senior
Notes, as provided in the Twelfth Supplemental Indenture. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture. </P>

principal amount of the Senior Notes at the time Outstanding, on behalf of the holders of all Senior Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Senior Note issued upon the registration of transfer hereof or in exchange
hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Indenture contains provisions for

that would be due if the Senior Notes matured on the Par Call Date, not including any portion of the payments of interest accrued as of such Redemption Date, discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate, plus 20 basis points, plus, in the case of each of (i)&nbsp;and (ii), accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed to, but excluding, such Redemption
