Corporation (i) by check mailed to the address of the Person entitled thereto as such address shall appear on the Security Register or (ii) by transfer to an account maintained by the payee located in the United States. 

The Securities will be redeemable at any time and from time to time. Prior to August 15, 2021 (three months prior to the maturity
date), the Securities will be redeemable, in whole or in part, at the option of the Corporation, at a Redemption Price equal to the greater of (i) 100% of their principal amount and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate,
plus 25 basis points, plus accrued and unpaid interest thereon to, but not including, the Redemption Date. 
 On or after
August 15, 2021, (three months prior to the maturity date), the Securities will be redeemable, in whole or in part, at the option of the Corporation, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid
interest thereon to, but not including, the Redemption Date.

Reference Treasury Dealer and any Redemption Date, the average, as determined by the Corporation, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the

payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Date referred to on the face hereof. Securities (or portions thereof) for whose redemption provision is made
in accordance with the Indenture shall cease to bear interest from and after the Redemption Date. 







 In the event of redemption of this Security in part only, a new Security or Securities for
the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 If a Change of
Control Triggering Event occurs with respect to the Securities, unless the Corporation has exercised its right to redeem the Securities, Holders of the Securities that have not been redeemed shall have the right to require the Corporation to

Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities
as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, the Corporation shall be required to comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control provisions of the Indenture by virtue of such conflicts.

transaction (including, without limitation, any merger or amalgamation) the result of which is that one or more “persons” (as such term is used in Section 13(d) of the Exchange Act) becomes the beneficial owner (as defined in Rules

Corporation. 







 Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of

 The Corporation shall not be required to make a Change of Control Offer with respect to the Securities upon a
Change of Control Triggering Event if a third party makes an equivalent offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control Offer made by the Corporation and such third party purchases all the
Securities properly tendered and not withdrawn under its offer. 
 The failure by the Corporation to comply with its obligations
in the event of a Change of Control Triggering Event described above for a period of 60 days after written notice to the Corporation by the Trustee or to the Corporation and the Trustee by the Holders of not less than 25% in principal amount of the
Outstanding Securities will constitute an Event of Default with respect to the Securities. If such an Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in principal

obligations of the Corporation and the rights of the Holders under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding.
The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Corporation
with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by or on behalf of the Holder of this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security 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 Security. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest on this Security at the times, place, and rate, and in the coin or currency, herein prescribed.

aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities are issuable only in
registered form without coupons in denominations of $2,000 and integral multiples of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of
Securities of a different authorized denomination, as requested by the Holder surrendering the same. 







 No service charge shall be made for any registration of transfer or exchange of Securities,
but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to the time of due presentment of this Security for registration of transfer, the Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Corporation, the Trustee nor any agent shall be affected by notice to the contrary. 

Interest on this Security shall be computed on the basis of a 360-day year of twelve 30-day months. 

If at any time, (i) the Depositary notified the Corporation that it is unwilling or unable to continue as Depositary or if at any
time the Depositary shall no longer be registered or in good standing under the Exchange Act or other applicable statute or regulation and a successor Depositary is not appointed by the Corporation within 90 days after the Corporation received
such notice or becomes aware of such condition, as the case may be, or (ii) the Corporation determines that the Securities shall no longer be represented by a global Security or Securities or (iii) any Event of Default shall have occurred
and be continuing, then in such event the Corporation will execute and the Trustee will authenticate and deliver Securities in definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal
amount of this Security in exchange for this Security. Such Securities in definitive registered form shall be registered in such names and issued in such authorized denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered. 
 The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York. 
 All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
