The Company shall pay interest on such principal amount at the rate of 5.375% per annum, until payment of such principal amount has been made or duly provided for, semi-annually in arrears on May 15 and November 15 of each year (each, an “Interest Payment Date”). Interest shall be payable on each Interest Payment Date, commencing on November 15, 2017, and at the stated maturity or earlier redemption or repayment (the “Maturity Date”).

The principal of and interest on this Note are payable in immediately available funds in such coin or currency of the United States as at the time of payment is legal tender for payment of public and private debts, at the office or agency of the Company designated as provided in the Indenture. However, interest may be paid, at the option of the Company, by check mailed to the person entitled thereto at his address last appearing on the registry books of the Company relating to the Notes. Notwithstanding the preceding sentence, payments of principal of and interest payable on the Maturity Date shall be made by wire transfer of immediately available funds to a designated account maintained in the United States upon (i) receipt of written notice by the Paying Agent (as described on the reverse hereof) from the registered holder hereof not less than one Business Day prior to the due date of such principal and (ii) presentation of this Note to the Paying Agent, at U.S. Bank National Association, Corporate Trust Services, 21 South Street, Morristown, New Jersey 07960.

Notwithstanding the foregoing, installments of interest on this Note that are due and payable on Interest Payment Dates falling on or prior to a redemption date shall be payable on the Interest Payment Date to the holders of this Note as of the close of business on the relevant record date according to this Note and the Indenture. In determining the present values of the Remaining Scheduled Payments, the Company will discount such payments to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points.

(b) Notice of any redemption shall be given at least 30 days but not more than 60 days before the redemption date to each holder of the Notes to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest shall cease

to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes shall be selected by the Trustee on a pro rata basis to the extent practicable in accordance with its customary procedures or applicable procedures of the Depository.

(c) Prior to publishing any notice of redemption in connection with a redemption pursuant to Section 3(a) hereof, the Company will deliver to the Trustee an Officer’s Certificate signed by the Chief Financial Officer or a Senior Vice President of the Company stating that the Company is entitled to redeem the Notes and that the conditions precedent to redemption have occurred.

For purposes of the above:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes (assuming for this purpose that the Notes mature on the Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, (2) if the Company obtains fewer than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations for such redemption date or (3) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers, or their respective successors, as may be appointed from time to time by the Company; provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “primary treasury dealer”), the Company will substitute another primary treasury dealer.

“Reference Treasury Dealers” means Barclays Capital Inc., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, TD Securities (USA) LLC, and each of their respective successors and any other primary treasury dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer as of 3:30 p.m., New York City time, on the third business day preceding such redemption date.

“Remaining Scheduled Payments” means, with respect to any Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due

after the related redemption date but for such redemption, assuming for this purpose that the Notes mature on the Par Call Date; provided, however, that, if such redemption date is not an interest payment date with respect to such Note, the amount of the next scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date or in the case of a discharge, prior to the deposit date) of the applicable Comparable Treasury Issue. In determining this rate, the Company will assume a price for the applicable Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date.

(d) Upon the occurrence of a Change in Control Repurchase Event, Section 2.7 of the First Supplemental Indenture shall apply to the extent applicable.

(e) Any notice of redemption may be given prior to the completion of any event or transaction related to such redemption, including any offering or other corporate transaction, and any such redemption or notice may be subject to one or more conditions precedent, including the completion of the related offering or corporate transaction. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice will state that the redemption date may be delayed until such time as any or all of such conditions have been satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions have not been satisfied by the redemption date, or by the redemption date so delayed.

SECTION 4. Defeasance. The provisions of Article 8 of the First Supplemental Indenture and Article 14 of the Indenture apply to this Note.

SECTION 5. Events of Default.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the holders of this Note under the Indenture at any time by the Company with the consent of the holders of not less than a majority of the aggregate principal amount of the Notes then Outstanding and affected by such amendment and modification. The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Notes then outstanding on behalf of the holders of all such 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 Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

No recourse shall be had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer, or director, as such, past, present, or future, of the Company or any predecessor or successor corporation, whether by virtue of any constitution, statute, or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for issue hereof, expressly waived and released.

SECTION 7. Obligations Unconditional. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place, and rate, and in the coin or currency, herein prescribed.

SECTION 8. Authorized Denominations. The Notes are issuable only as registered Notes without coupons in the minimum denominations of Two Thousand Dollars ($2,000) and any whole multiples of One Thousand Dollars ($1,000).

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, the Paying Agent, and any agent of the Company may treat the person in whose name this Note is registered as the absolute owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note be overdue, and
