the words “herein,” “hereof” and “hereunder” and other words of similar import refer to the Indenture and this First Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision;

(3)

capitalized terms used but not defined herein are used as they are defined in the Indenture; and

(4)

any term defined both in the Indenture and in this First Supplemental Indenture shall have the meaning set forth in this First Supplemental Indenture.

“Attributable Indebtedness” with respect to a Sale/Leaseback Transaction means, as of the time of determination, (i) if the obligation with respect to such Sale/Leaseback Transaction is a Finance Lease Obligation, the amount of such obligation determined in accordance with GAAP and included in the financial statements of the lessee or (ii) if the obligation with respect to such Sale/Leaseback Transaction is not a Finance Lease Obligation, the total Net Amount of Rent required to be paid by the lessee under such lease during the remaining term thereof (including any period for which the lease has been extended), discounted from the respective due dates thereof to such determination date at the rate per annum borne by the Notes compounded semi-annually.

“Change of Control” means the occurrence of any of the following after the date of issuance of the Notes:

(1)

(2)

the consummation of any transaction, including without limitation any merger or consolidation, the result of which is that a “person” or “group” (within the meaning of Sections 13(d) and 14(d)(2) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Company;

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control solely because the Company shall become a direct or indirect wholly-owned subsidiary of a holding company if the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction.

THE NOTES

SECTION 2.01 Title and Terms.

There are hereby created under the Indenture a series of Securities known and designated as the “2.700% Senior Notes due 2031” of the Company. The aggregate principal amount of Notes that may be authenticated and delivered under this First Supplemental Indenture is initially limited to $400,000,000.

The Company may, subject to the applicable requirements of Section 3.01 of the Indenture, without notice to or the consent of the Holders of the Notes, issue in separate offerings additional notes having the same ranking, interest rate, maturity and other terms as the Notes (other than the date of issuance, price to public and, under certain circumstances, the initial interest payment date). Any such additional notes, together with the Notes, will form a single series of Securities under the Indenture; provided that if any such additional notes are not fungible with the Notes for U.S. federal income tax purposes, such additional notes will be issued with a different CUSIP number (or other applicable identifying number).

The Stated Maturity for payment of principal of the Notes shall be March 18, 2031. The Notes shall bear interest at the rate of 2.700% per annum, from March 18, 2021 or the most recent interest payment date to which interest has been paid or duly provided for, payable semi-annually in arrears on March 18 and September 18 of each year (commencing September 18, 2021), to the Persons in whose names the Notes are registered at the close of business on March 3 and September 3 whether or not a Business Day, as the case may be, next preceding such interest payment date (each, a “Regular Record Date”), until principal thereof is paid or made available for payment.

The Notes shall be initially issued in the form of a Global Security and the Depositary for the Notes shall be The Depository Trust Company, New York, New York. The original issue date of the Notes shall be March 18, 2021, and the Notes shall not constitute Original Issue Discount Securities under the Indenture.

Except as provided in Section 2.03 hereof, the Company shall have no obligation to redeem, purchase or repay the Notes pursuant to any mandatory redemption, sinking fund or analogous provisions or at the option of a Holder thereof.

The Notes shall be in registered book-entry form and shall be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Notes shall not be guaranteed or secured by any collateral and shall rank equally with the Company’s other unsecured senior indebtedness.

The Notes shall be subject to Article VIII of the Base Indenture.

The Notes shall be in the form attached hereto as Exhibit A.

SECTION 2.02 Optional Redemption.

(a) The provisions of Article XI of the Indenture, as supplemented by the provisions of this First Supplemental Indenture, shall apply to the Notes.

(b) On or after December 18, 2030 (which is the date that is three months prior to the Stated Maturity for payment of principal of the Notes, the “Par Call Date”), the Notes will be redeemable, as a whole or in part, at the option of the Company at any time, 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 the date of the redemption. At any time prior to the Par Call Date, the Notes may be redeemed, as a whole or in part, at the option of the Company 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 thereon that would be due if the Notes matured on the Par Call 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 20 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to the date of redemption.

Unless the Company defaults in payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

SECTION 2.03 Purchase upon a Change of Control Triggering Event.

(a) Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Company has exercised its right to redeem the Notes in full by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of the Notes will have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date.

(b) Unless the Company has exercised its right to redeem the Notes, within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to the Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to send, by first class mail, (or with respect to Global Securities, to the extent permitted or required by Applicable Procedures of the Depositary, send electronically) a notice to each Holder of the Notes, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. The notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date the notice is mailed or sent, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior or sent to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

(i) accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(d) The Company will not be required to make a Change of Control Offer with respect to the Notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all the Notes properly tendered and not withdrawn under its offer.

(e) The Company will comply in all material respects with the requirements of Rule 14e-1 under 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 Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under this Section 2.03 by virtue of any such conflict.

SECTION 2.04 Limitation on Liens.

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Issuer shall also pay interest on overdue principal or installments of interest at such rate. The interest so payable, and punctually paid or duly provided for, on any interest payment date will, as provided in the Indenture, be paid to the Person in whose name this Note is registered as of the Regular Record Date.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated herein and referred to in the within-mentioned Indenture.

[REVERSE OF GLOBAL NOTE]

This Note is one of a duly authorized issue of securities of the Issuer (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of March 18, 2021 (the “Base Indenture”), between the Issuer and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of March 18, 2021 (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Issuer and the Trustee, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof (the “Notes”). All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

On or after December 18, 2030 (which is the date that is three months prior to the Stated Maturity for payment of principal of the Notes, the “Par Call Date”), the Notes will be redeemable, as a whole or in part, at the option of the Company at any time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, on the principal amount being redeemed to the date of the redemption. At any time prior to the Par Call Date, the Notes may be redeemed, as a whole or in part, at the option of the Issuer at a redemption price equal to the greater of (a) 100% of the principal amount to be redeemed and (b) the sum of the present values of the Remaining Scheduled Payments thereon that would be due if the Notes matured on the Par Call 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 20 basis points, plus, in either case, accrued and unpaid interest, if any, on the principal amount being redeemed to the date of redemption. Unless the Issuer defaults in payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Issuer has exercised its right to redeem the Notes in full, by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of the Notes will have the right to require the Issuer to purchase all or a portion of the Notes pursuant to a Change of Control Offer, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of the Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date.

Unless the Issuer has exercised its right to redeem the Notes, within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to the Notes or, at the Issuer’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Issuer will be required to send by first class mail (or, to the extent permitted or required by Applicable Procedures of the Depositary, send electronically), a notice to each Holder of the Notes, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. The notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date the notice is

A-4

mailed or sent, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed or sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(i) accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit or cause a third party to deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased and that all conditions precedent to the Change of Control Offer and to the purchase by the Issuer of Notes pursuant to the Change of Control Offer have been complied with.

The Issuer will not be required to make a Change of Control Offer with respect to the Notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Issuer and such third party purchases all the Notes properly tendered and not withdrawn under its offer.

The Issuer will comply in all material respects with the requirements of Rule 14e-1 under 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 Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer will comply with those securities laws and regulations and will not be deemed to have breached its obligations under Section 2.03 of the First Supplemental Indenture by virtue of any such conflict.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Notes or certain restrictive covenants and Events of Default with respect to the Notes, in each case upon compliance with certain conditions set forth in the Indenture. Such provisions shall be applicable to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and interest on 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, with the consent of Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of each series affected by such supplemental indenture, the Issuer and the Trustee at any time to enter into an indenture or supplemental indenture for the purpose of adding any provisions to or

A-5

changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of Securities of such series under the Indenture. The Indenture also permits, with certain exceptions as therein provided, prior to the acceleration of the maturity of the Securities of any series, the Holders of a majority in aggregate principal amount of the Securities of that series at the time Outstanding may, on behalf of the Holders of all the Securities of that series, waive any past default or Event of Default and its consequences for that series specified in the terms thereof. Any such consent or waiver by the Holder of any such Security shall be conclusive and binding upon such Holder and upon all future Holders of such Security and of any Security issued upon the registration of transfer hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon such Security.

As provided in and subject to the provisions of the Indenture, no Holder of any Security will have any right to institute any action or proceeding upon or under or with respect to the Indenture, for the appointment of a receiver or trustee or for any other remedy, unless (i) such Holder previously has given to the Trustee written notice of an Event of Default with respect to the Securities of such series and of the continuance thereof, (ii) Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series have made written request to the Trustee to institute such action or proceeding with respect to such Event of Default and have offered to the Trustee such security or indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby and (iii) the Trustee, for 60 days after its receipt of such notice, request and offer of security or indemnity, has failed to institute such action or proceeding and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by Holders of a majority in aggregate principal amount of the Outstanding Securities of that series. The foregoing shall not apply to any suit instituted by the Holder of a Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed therein.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, 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.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Prior to due presentation for registration of transfer of this Note, the Issuer, the Trustee, any Paying Agent or any Security Registrar may deem and treat the Person in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note shall be overdue, and none of the Issuer, the Trustee, any Paying Agent or any Security Registrar shall be affected by notice to the contrary.
