(b)    The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall be paid to
the Persons in whose names the 2024 Notes (or one or more predecessor securities) are registered on the Regular Record Date for such Interest Payment Date, which will be (i) the close of business on the Business Day immediately preceding such
Interest Payment Date so long as all of the 2024 Notes remain in book-entry only form or (ii) the fifteenth calendar day, whether or not such day is a Business Day, immediately preceding such Interest Payment Date if any of the 2024 Notes do

attached as Exhibit A.

 Section 2.11.    Limitation on Liens. The 2024 Notes shall
be subject to the limitation on liens covenant set forth in Article Four of this Supplemental Indenture. 

Section 2.12.    Optional Redemption. Except as described in Article III of the Original Indenture and this
Section 2.12, the 2024 Notes may not be redeemed prior to the 2024 Maturity Date; provided however, that, to the extent any provision of Section 2.12 of this Supplemental Indenture is inconsistent with Article III of the Original
Indenture, the provisions of Section 2.12 of this Supplemental Indenture shall supersede the provisions of Article III of the Original Indenture with respect to the 2024 Notes (but not any other series of Notes). Prior to August 15, 2024
(the “2024 Par Call Date”), the Company shall have the right to redeem the 2024 Notes, at its option, at any time in whole, or from time to time in part, at a redemption price equal to the greater of: 

(i)    100% of the principal amount of the 2024 Notes to be redeemed; and 

(ii)    the sum of the present values of the remaining scheduled payments of principal and interest on the
2024 Notes to be redeemed that would be due if such 2024 Notes matured on the 2024 Par Call Date (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption 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 each case, accrued and unpaid interest on the principal amount being redeemed to, but excluding, the redemption date. 

On or after the 2024 Par Call Date, the Company shall have the right to redeem the 2024 Notes, at its option, at any time in whole, or from
time to time in part, at a redemption price equal to 100% of the principal amount of the 2024 Notes to be redeemed, plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the redemption date. 

The election of the Company to redeem any of the 2024 Notes shall be evidenced by a notice of redemption to the Trustee at least 45 days (or
such shorter period acceptable to the Trustee in its sole discretion) prior to the redemption date specified in such notice. Notwithstanding Section 3.02(a) of the Original Indenture, the Company’s election to redeem any of the 2024 Notes
need not be evidenced by a Board Resolution. 
 Notice of redemption to each Holder of the 2024 Notes to be redeemed as a whole or in part
shall be given by the Trustee, in the manner provided in Section 15.10 of the Original Indenture, no less than 10 or more than 60 days prior to the date fixed for redemption. Any notice which is given in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder receives the notice. In any case, failure duly to give such notice, or any defect in such notice, to the Holder of any 2024 Note designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other 2024 Note. 
 Notwithstanding the foregoing, installments
of interest on the 2024 Notes that are due and payable on an Interest Payment Date falling on our prior to a redemption date shall be payable on such Interest Payment Date to the Holders as of the close of business on the relevant Regular Record
Date.

Original Indenture. Such order shall specify the amount of the 2029 Notes to be authenticated, the date on which the original issue of 2029 Notes is to be authenticated and the name or names of the initial Holder or Holders. The
aggregate principal amount of 2029 Notes that may initially be outstanding shall not exceed $800,000,000; provided, however, that the authorized aggregate principal amount of the 2029 Notes may be increased above such amount without

for, on any Interest Payment Date shall be paid to the Persons in whose names the 2029 Notes (or one or more predecessor securities) are registered on the Regular Record Date for such Interest Payment Date, which will be (i) the close of
business on the Business Day immediately preceding such Interest Payment Date so long as all of the 2029 Notes remain in book-entry only form or (ii) the fifteenth calendar day, whether or not such day is a Business Day, immediately preceding
such Interest Payment Date if any of the 2029 Notes do not remain in book-entry only form. 

Section 3.05.    Place of Payment. Principal and interest payments on the 2029 Notes will be made by the
Company to DTC while it is the Depositary for the 2029 Notes, or if DTC shall cease to be the Depositary for the 2029 Notes, to the Trustee at its offices, as paying agent.

	Maturity Date: September 15, 2024	  	CUSIP No. 30034W AA4
	Registered Holder:

pay interest thereon from September 9, 2019, or from the most recent Interest Payment Date to which interest has been duly paid or provided for, initially on March 15, 2020, and thereafter semi-annually on March 15 and
September 15 of each year, at the interest rate stated above, until the date on which payment of such principal sum has been made or duly provided for. The interest so payable on any Interest Payment Date will be paid to the person in
whose name this Note is registered on the Regular Record Date for such Interest Payment Date, which will be (i) the close of business on the Business Day immediately preceding such Interest Payment Date so long as all of the Notes (as defined
below) remain in book-entry only form or (ii) the fifteenth calendar day, whether or not such day is a Business Day, immediately preceding such Interest Payment Date if any of the Notes do not remain in book-entry only form, except as otherwise
provided in the Indenture. 
 The principal and interest payments on this Note will be made by the Company to the registered Holder named
above. All such payments shall be made in such coin or currency of the United States of America as at the time of payment is legally tender for payment of public and private debts. 

This Note is one of a duly authorized issue of notes of the Company (herein called the “Notes”), issued under an Indenture,
dated as of June 1, 2004, as supplemented by the Sixth Supplemental Indenture, dated as of June 4, 2018 and the Seventh Supplemental Indenture, dated as of September 9, 2019 (herein called the “Indenture,” which term
shall have the meaning 

  
 A-1 













 
assigned to it in such instruments), between the Company and The Bank of New York Mellon Trust Company, N.A. (successor to BNY Midwest Trust Company), as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture). Reference is made to the Indenture and any supplemental indenture thereto for the provisions relating, among other things, to the respective rights of
the Company, the Trustee and the Holders of the Notes, and the terms on which the Notes are authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to
$800,000,000; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount by a Board Resolution authorizing such increase. Any additional notes issued pursuant to such
increase must have the same ranking, interest rate, maturity and other terms (except for the price to the public, the Original Issue Date and the first Interest Payment Date, as applicable) as the Notes. Any such additional notes, together with the
Notes, will constitute a single series of Notes under the Indenture; provided that if any such additional notes are not fungible for U.S. federal income tax purposes with the Notes, such additional notes will be issued under a separate CUSIP number.

 Prior to August 15, 2024 (the “Par Call Date”), the Company shall have the right to redeem the Notes of this
series, at its option, at any time in whole, or from time to time in part, at a redemption price equal to the greater of (i) 100% of the principal amount to be redeemed and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the Notes to be redeemed that would be due if such Notes matured on the Par Call Date (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of
redemption 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 each case, accrued and
unpaid interest on the principal amount of the Notes being redeemed to, but excluding, the redemption date. 
 On or after the Par Call
Date, the Company shall have the right to redeem the Notes, at its option, at any time in whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest
on the principal amount being redeemed to, but excluding, the redemption date. 
 For purposes of determining the optional redemption price:

 “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a
maturity comparable to the remaining term of the Notes to be redeemed (assuming, for this purpose, that the Notes matured on the Par 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 comparable maturity to the remaining term of the Notes. 
 “Comparable Treasury
Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations; (2) if
the Quotation Agent obtains fewer than four of such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations; or (3) if only one such Reference Treasury Dealer Quotation is received, such Reference
Treasury Dealer Quotation. 

  
 A-2 













 “Quotation Agent” means the Reference Treasury Dealer appointed by the
Company. 
 “Reference Treasury Dealer” means each of (1) BofA Securities, Inc., Citigroup Global Markets Inc., J.P.
Morgan Securities LLC and Wells Fargo Securities, LLC and (2) a Primary Treasury Dealer (as defined below) selected by MUFG Securities Americas Inc., or their respective affiliates and successors, unless any of them ceases to be a primary U.S.
government securities dealer in the United States of America (a “Primary Treasury Dealer”), in which case the Company will substitute therefor another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by the Quotation Agent, 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 Quotation Agent by such Reference Treasury Dealer
at 5:00 p.m., New York City time, on the third Business Day preceding 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 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. 
 The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this Note and (ii) the Company’s obligations under the Indenture and this Note with respect to certain covenants and related Events of Default, upon compliance by the Company with certain conditions set forth in the
Indenture. 
 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of this Note may be declared due
and payable in the manner and with the effect provided in the Indenture. 
 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 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 aggregate principal amount of the securities at the time outstanding of all series to be affected, considered as one class. The Indenture contains provisions permitting the Holders of a majority in
aggregate principal amount of the securities of any series at the time outstanding, on behalf of the Holders of all securities of such series, to waive certain past defaults or Events of Default 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 in exchange, substitution or upon the registration or transfer hereof, irrespective of
whether or not notation of such consent or waiver is made upon this Note. 
 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 premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency,
herein provided. 

  
 A-3 













 This Note is issuable as a registered Note only, in the minimum denomination of $2,000 and
integral multiples of $1,000. 
 As provided in the Indenture, this Note is transferable by the registered Holder hereof in person or by his
attorney duly authorized in writing on the books of the Company at the office or agency to be maintained by the Company for that purpose. Upon any registration of transfer, a new registered Note or Notes, of authorized denomination or
denominations, and in the same aggregate principal amount, will be issued to the transferee in exchange therefore. 
 The Company, the
Trustee, any paying agent and any Authenticating Agent may deem and treat the registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of or on account of the
principal of (and premium, if any) and interest on this Note as herein provided and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Authenticating Agent shall be affected by any notice to the contrary.

 No recourse shall be had for the payment of the principal of or any premium or 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 or against any past, present or future stockholder, officer or member of the Board of Directors, as such, of the
Company, whether by virtue of any constitution, state 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 the issue hereof,
expressly waived and released. 
 This Note shall be governed by and deemed to be a contract made under, and construed in accordance with,
the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of the State of New York without regard to conflicts of law principles thereof. 

All terms used in this Note which are defined in the Indenture and not defined herein shall have the meaning assigned to them in the
Indenture. 
 This Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until the
certificate of authentication on the face hereof is manually signed by the Trustee.
