 2. Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted
Interest) to the Persons who are Holders of Notes at the close of business on the May 15 or November 15 preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 307 of the Original Indenture with respect to Defaulted Interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a Paying Agent on or after the
Stated Maturity thereof. The Notes shall be payable as to principal, premium, if any, and interest at the office or agency maintained by the Issuer for such purpose (which initially is the corporate trust office of Wells Fargo Bank, National
Association at 333 S. Grand Avenue, 5th Floor, Los Angeles, California 90071) or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, and interest and premium, if any, on, (a) each Global Security and (b) all other Notes aggregating at least
$1,000,000 in principal amount the Holder of which shall have provided wire transfer instructions to the Issuer or the Paying Agent to an account in the United States prior to the applicable record date. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 3. Paying
Agent and Registrar. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, has been appointed to act as Paying Agent and Security Registrar. The Issuer may change any Paying Agent or Security Registrar without
notice to any Holder. The Issuer may act in any such capacity. 
 4. Indenture. The Issuer issued the Notes under an Indenture dated
as of November 20, 2012 (the “Original Indenture”), as supplemented by the Fourth Supplemental Indenture dated as of November 14, 2019 (the “Supplemental Indenture” and, together with the Original Indenture, the
“Indenture”), between the Issuer and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling to the extent permitted by law. The Notes are the obligation of the Issuer, initially in aggregate principal amount of $500,000,000. The Issuer may issue an unlimited principal amount of
Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same series (with identical terms other than with respect to the issue date and first payment of
interest) as the initial Notes for the purposes indicated in Section 3.02 of the Supplemental Indenture). 
 5. Optional
Redemption. 
 (a) At its option, the Issuer may choose to redeem all or any portion of the Notes, at once or from time to time. 

  
 A - 3 













 (b) To redeem the Notes prior to the Call Date, the Issuer must pay a Redemption Price equal
to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest in respect of the Notes to be redeemed (exclusive of interest
accrued to the Redemption Date) through the Call Date discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day
months) at a rate equal to the sum of the Treasury Rate (as defined below) plus 30 basis points, plus in either case, any accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders on the relevant Regular
Record Date to receive interest due on the relevant Interest Payment Date). To redeem the Notes on or after the Call Date, the Issuer must pay a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus any accrued and
unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date). 

For purposes of determining the Redemption Price with respect to any Redemption Date prior to the Call Date, the following definitions shall
apply: 
 “Call Date” means September 1, 2029 (the date that is three months prior to the maturity date of the Notes).

 “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 to the Call Date 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 a comparable maturity to the remaining term to the Call Date of the Notes to be redeemed. 

“Comparable Treasury Price” means, for any Redemption Date, the average of the Reference Treasury Dealer Quotations for such
Redemption Date as determined by the Company. 
 “Independent Investment Banker” means one of the Reference Treasury
Dealers appointed by the Trustee after consultation with the Company. 
 “Reference Treasury Dealer” means each of Barclays
Capital Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC or their respective affiliates that are primary U.S. government securities dealers in the United States (a “Primary Treasury Dealer”), and their respective
successors; provided, however, that if any of the foregoing and its affiliates and subsidiaries shall not be a Primary Treasury Dealer at the appropriate time, the Company shall 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 Independent Investment Banker, 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 Independent Investment Banker by
such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

  
 A - 4 













 “Treasury Rate” means, with respect to any Redemption Date, the rate per
annum equal to the semiannual equivalent yield to maturity (computed by the Company as of the second Business Day immediately preceding such Redemption Date, or in the case of a satisfaction and discharge, the second Business Day immediately
preceding the date of deposit with the Trustee or any paying agent) 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 election of the Issuer to redeem any Notes need not be evidenced by a Board Resolution. 

6. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the
Notes or to repurchase them at the option of the Holders. 
 7. Notice of Redemption. Any notice of redemption shall be given at
least 15 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held
by a Holder are to be redeemed. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the Redemption Price has been paid. 

8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Security Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents, and the Issuer may require a Holder to pay any taxes or other governmental charges imposed in relation thereto. 

9. Persons Deemed Owners. The registered holder of a Note shall be treated as its owner for all purposes. 

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of
the Holders of a majority in principal amount of the then Outstanding Securities of each series affected thereby, any past default relating to the Notes may be waived with the consent of the Holders of a majority in principal amount of the then
Outstanding Notes, and the Holders of a majority in principal amount of all Outstanding Securities may on behalf of the Holders of all Outstanding Securities waive any other past default under the Indenture. Without the consent of any Holder of a
Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 901 of the Indenture, including to cure any ambiguity, defect or inconsistency, to evidence the succession of another Person to the Company and
provide for the assumption by any such successor of the covenants of the Company herein and in the Indenture, to make any change that does not adversely affect the rights under the Indenture of any Holder of the Notes in any material respect, to
comply with the requirements of the Commission to effect or maintain the qualification of the Indenture under the Trust Indenture Act, to evidence or provide for the acceptance of appointment under the Indenture of a successor or additional Trustee,
to add to the covenants of the Issuer or any additional Events of Default, to secure the Notes or to establish the form or terms of any other series of Securities. 

  
 A - 5

(iii) default in the performance or breach of any covenant of the Company in the Indenture (other than a covenant referred to in clause (i) or (ii) or included in the Indenture for the sole benefit of a series of Securities other than the
Notes), and continuance of such default for a period of 90 days (or, in the case of a default under the covenant in Section 704 of the Indenture, 120 days) after there has been given, by registered or certified mail, to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of all series affected thereby a written notice specifying such default and requiring it to be remedied and stating that such
notice is a “Notice of Default” under the Indenture; and (iv) certain events of bankruptcy, insolvency or reorganization with respect to the Issuer. If any Event of Default referred to in clause (i) or (ii) occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of the then Outstanding Notes may declare all the Notes to be due and payable. If an Event of Default referred to in clause (iii) occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of all Outstanding Securities of all series affected by such default, including the Notes, may declare all such Securities to be due and payable. Notwithstanding the foregoing, in the case of an
Event of Default referred to in clause (iv), all Outstanding Securities shall become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture.
