The Company shall have the right to reopen the Securities of the Series Due 2049 for the issuance of additional Securities
of such series (“Additional Securities of the Series Due 2049”). The issuance of any Additional Securities of the Series

(f)   
The Securities of the Series Due 2049 shall bear interest at the rate of 3.30% per annum, and such interest shall accrue
from August 14, 2019 (or from the most recent Interest Payment Date to which interest on the Securities of the Series Due 2049
has been paid or provided for). The Interest Payment Dates for the Securities of the Series Due 2049 shall be March 1 and September

the principal amount of the Securities of the Series Due 2049 being redeemed or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest on the Securities of the Series Due 2049 being redeemed that would be due if such
Securities of the Series Due 2049 matured on the Early Call Date but for the redemption (exclusive of interest accrued to the Redemption
Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the

the Redemption Date. At any time on or after the Early Call Date, the Company may redeem the Securities of the Series Due 2049,
in whole or in part from time to time, at 100% of the principal amount of the Securities of the Series Due 2049 being redeemed
plus accrued and unpaid interest to, but not including, the Redemption Date.

 

Such Redemption Date shall be set forth in
an Officer’s Certificate delivered to the Trustee on or before the Redemption Date and upon which the Trustee may conclusively
rely.

 

For purposes of this paragraph (h):

 

    3 

     

    

 

“Treasury Rate” means, with respect
to any Redemption Date, the rate per year equal to the semiannual equivalent yield to maturity or interpolated (on a day count
basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal
amount) equal to the Comparable Treasury Price for such Redemption Date; provided that, if the Independent Investment Banker
shall determine that there is no such Comparable Treasury Issue, such rate per year shall be equal to the estimated semiannual
equivalent yield to maturity that a United States Treasury security having a maturity comparable to the remaining term of the Securities
of the Series Due 2049 to be redeemed (assuming, for this purpose, that the Securities of the Series Due 2049 mature on the Early
Call Date) would bear, if such security were available, such estimate to be made by the Reference Treasury Dealers on the basis
of interpolation, extrapolation and other accepted financial practices, taking into account (a) the yields to maturity of United
States Treasury securities of other maturities, (b) yields to maturity of other U.S. dollar denominated debt securities having
a maturity comparable to the remaining term of the Securities of the Series Due 2049 to be redeemed (assuming, for this purpose,
that the Securities of the Series Due 2049 mature on the Early Call Date) and (c) applicable interest rate spreads between
United States Treasury securities and such other debt securities, all as of 5:00 p.m., New York City time, on the third Business
Day preceding such Redemption Date.

 

“Comparable Treasury Issue” means
the United States Treasury security or securities selected by the Independent Investment Banker as having an actual or interpolated
maturity comparable to the remaining term of the Securities of the Series Due 2049 being redeemed (assuming, for this purpose,
that the Securities of the Series Due 2049 mature on the Early Call Date) 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 a comparable maturity to
the remaining term of such Securities of the Series Due 2049.

 

“Independent Investment Banker”
means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company.

 

“Comparable Treasury Price” means,
with respect to any Redemption Date, (a) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such quotations.

 

“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, 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 Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding
such redemption date.

 

“Reference Treasury Dealer” means
each of BofA Securities, Inc. and Wells Fargo Securities, LLC and their respective successors, one primary U.S. government securities
dealer (a “Primary Treasury Dealer”) selected by each of MUFG Securities Americas Inc. and PNC Capital Markets LLC
and two other Primary Treasury Dealers selected by the Company. If any Reference Treasury Dealer shall cease to be a Primary Treasury
Dealer, the Company will select another Primary Treasury Dealer which will be substituted for that dealer.

 

    4 

     

    

 

(i)    
The Securities of the Series Due 2049 shall not be subject to any sinking fund and shall not be redeemable at the option
of the Holders thereof.

 

(j)    
The Securities of the Series Due 2049 shall initially be issued in whole in the form of one or more Global Securities. If
individual securities of the Series Due 2049 are issued under the conditions specified in Section 2.05 of the Indenture, individual
certificates will be issued in denominations of $1,000 or any integral multiple thereof.

 

Such Securities of the Series Due 2049 and
Additional Securities of the Series Due 2049, if any, shall be initially authenticated and delivered from time to time upon delivery
to the Trustee of the documents required by Section 3.01 of the Indenture and the form of Securities for the Securities of the
Series Due 2049 and Additional Securities of the Series Due 2049, if any, substantially in the form of Security attached hereto
as Appendix I, which is incorporated herein by reference.

the manner and with the effect provided in the Indenture. Upon payment (i) of the amount of principal so declared due and payable

of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by
the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding
of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in principal amount
of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall bind
such Holder and all future Holders of this Security and of any Security 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 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 Company, which is absolute and unconditional,
to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency,
herein prescribed.

 

As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of
this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium,
if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series, of authorized denominations and for the same Stated Maturity and aggregate
principal amount, will be issued to the designated transferee or transferees.

 

The Securities of this series are issuable
only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture
and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

 

    12

     

    

 

No service charge shall be made for any such
registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.

 

Prior to due presentment of this Security
for registration of transfer, the Company, the Trustee and any agent of the Company 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
Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 

The Indenture imposes certain limitations

all or substantially all of its properties or assets. All such covenants and limitations are subject to a number of important qualifications
and exceptions. The Company must report periodically to the Trustee on compliance with the covenants in the Indenture.

 

A director, officer, employee or shareholder,
as such, of the Company shall not have any liability for any obligations of the Company under this Security or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Security,
waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security.
