DB1/ 138804239.3

[FORM OF REVERSE OF NOTE]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of November 1, 2017 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer’s Certificate filed with the Trustee on June 20, 2023 creating the series designated on the face hereof (herein called the “Officer’s Certificate”), for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities of this series and of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

Interest and Payment.

The Securities of this series shall bear interest at a variable rate per annum (the “Interest Rate”) equal to Compounded SOFR (as defined below), minus 0.35% (negative 0.35%, the “Margin”).

If any Interest Payment Date falls on a day that is not a Business Day (as defined below), the Company will make the interest payment on the next succeeding Business Day unless that Business Day is in the next succeeding calendar month, in which case (other than in the case of the Stated Maturity Date, the New Maturity Date, a Redemption Date or a Repayment Date) the Company will make the interest payment on the immediately preceding Business Day. If an interest payment is made on the next succeeding Business Day, no interest will accrue as a result of the delay in payment. If the Stated Maturity Date, the New Maturity Date, a Redemption Date or a Repayment Date of the Securities of this series falls on a day that is not a Business Day, the payment due on such date will be postponed to the next succeeding Business Day, and no further interest will accrue in respect of such postponement.

On each Interest Payment Determination Date (as defined below) relating to the applicable Interest Payment Date, the Calculation Agent (as defined below) will calculate the amount of accrued interest payable on the Securities of this series by multiplying (i) the outstanding principal amount of the Securities of this series by (ii) the product of (a) the Interest Rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Observation Period divided by 360. In no event will the interest rate on the Securities of this series be less than zero.

“Calculation Agent” means a banking institution or trust company appointed by the Company to act as calculation agent, initially The Bank of New York Mellon.

    A - 4

DB1/ 138804239.3

Compounded SOFR. “Compounded SOFR” will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point):

(	SOFR IndexEnd	-1	)	x	360
	SOFR IndexStart				dc

where:

“SOFR IndexStart” = For periods other than the initial Interest Period, the SOFR Index value on the preceding Interest Payment Determination Date, and, for the initial Interest Period, the SOFR Index value on June 15, 2023;

“SOFR IndexEnd” = The SOFR Index value on the Interest Payment Determination Date relating to the applicable Interest Payment Date (or, in the final Interest Period, relating to the Stated Maturity Date or the New Maturity Date, as the case may be, or, in the case of a redemption or repayment of the Securities of this series, as the case may be, relating to the applicable Redemption Date or Repayment Date, respectively); and

“dc” is the number of calendar days in the relevant Observation Period.

For purposes of determining Compounded SOFR,

“Interest Payment Determination Date” means the date that is two U.S. Government Securities Business Days before each Interest Payment Date (or, in the final Interest Period, before the Stated Maturity Date or the New Maturity Date, as the case may be, or, in the case of a redemption or repayment of the Securities of this series, as the case may be, before the applicable Redemption Date or Repayment Date, respectively).

“Observation Period” means, in respect of each Interest Period, the period from and including the date that is two U.S. Government Securities Business Days preceding the first date in such Interest Period to but excluding the date that is two U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period (or, in the final Interest Period, preceding the Stated Maturity Date or the New Maturity Date, as the case may be, or, in the case of a redemption or a repayment of the Securities of this series, as the case may be, preceding the applicable Redemption Date or Repayment Date, respectively).

“SOFR Index” means, with respect to any U.S. Government Securities Business Day:

(1)the SOFR Index value as published by the SOFR Administrator (as defined below) as such index appears on the SOFR Administrator’s Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the “SOFR Index Determination Time”); provided that:

(2)if a SOFR Index value does not so appear as specified in (1) above at the SOFR Index Determination Time, then: (i) if a Benchmark Transition Event and its related

    A - 5

DB1/ 138804239.3

Benchmark Replacement Date (each, as defined below) have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “SOFR Index Unavailable Provisions” described below, or (ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “Effect of Benchmark Transition Event” provisions described below.

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (or a successor administrator of SOFR).

“SOFR Administrator’s Website” means the website of the Federal Reserve Bank of New York, currently at http://www.newyorkfed.org, or any successor source.

“U.S. Government Securities Business Day” means any day except for a Saturday, Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary in the Securities of this series, the Officer’s Certificate or the Indenture, if the Company or its designee (which may be an independent financial advisor or any other designee of the Company (any of such entities, a “Designee”)) determines on or prior to the relevant Reference Time (as defined below) that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth below under “Effect of Benchmark Transition Event” will thereafter apply to all determinations of the rate of interest payable on the Securities of this series.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the Interest Rate for each Interest Period on the Securities of this series will be an annual rate equal to the sum of the Benchmark Replacement and the applicable margin.

SOFR Index Unavailable Provisions. If a SOFR IndexStart or SOFR IndexEnd is not published on the associated Interest Payment Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the applicable Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator’s Website, initially located at https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information. For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to “calculation period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180-calendar days” shall be removed. If SOFR does not so appear for any day “i” in the Observation Period, SOFRi for

    A - 6

DB1/ 138804239.3

such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

Absent willful misconduct, bad faith or manifest error, the calculation of the applicable Interest Rate for each Interest Period by the Calculation Agent, or in certain circumstances described below, by the Company (or its Designee) will be final and binding on the Company, the Trustee, and the Holders of the Securities of this series.

None of the Trustee, Paying Agent, Security Registrar or Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, determine or designate any Benchmark Replacement Adjustment (as defined below), or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes (as defined below) are necessary or advisable, if any, in connection with any of the foregoing. In connection with the foregoing, each of the Trustee, Paying Agent and Registrar and Calculation Agent shall be entitled to conclusively rely on any determinations made by the Company (or its Designee) without independent investigation, and none will have any liability for actions taken at the direction of the Company in connection therewith.

None of the Trustee, Paying Agent, Security Registrar or Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties described in the Securities of this series, the Officer’s Certificate or the Indenture as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information contemplated by the Securities of this series, the Officer’s Certificate or the Indenture and reasonably required for the performance of such duties. In connection with any determinations made under the subsection “Effect of Benchmark Transition Event” below, none of the Trustee, Paying Agent, Registrar or Calculation Agent shall be responsible or liable for the actions or omissions of the Company (or its Designee), or for any failure or delay in the performance by the Company (or its Designee), nor shall any of the Trustee, Paying Agent, Registrar or Calculation Agent be under any obligation to oversee or monitor the performance of the Company (or its Designee).

Effect of Benchmark Transition Event.

Benchmark Replacement. If the Company (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Securities of this series in respect of such determination on such date and all determinations on all subsequent dates.

    A - 7

DB1/ 138804239.3

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company (or its Designee) will have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations. Any determination, decision or election that may be made by the Company (or its Designee) pursuant to the benchmark replacement provisions described in this subsection “Effect of Benchmark Transition Event,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, will be made in the Company’s (or its Designee’s) sole discretion, and, notwithstanding anything to the contrary in the Securities of this series, the Officer’s Certificate or the Indenture, shall become effective without consent from the holders of the Securities of this series or any other party.

Certain Defined Terms. As used herein, the following terms have the following meanings:

“Benchmark” means, initially, Compounded SOFR; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company (or its Designee) as of the Benchmark Replacement Date:

(1)the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2)the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; and

(3)the sum of: (a) the alternate rate of interest that has been selected by the Company (or its Designee) as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Company (or its Designee) as of the Benchmark Replacement Date:

(3)the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company (or its Designee) giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time.

The Benchmark Replacement Adjustment shall not include the Margin specified herein and such Margin shall be applied to the Benchmark Replacement to determine the interest payable on the Securities of this series.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of “Interest Period,” the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company (or its Designee) decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company (or its Designee) decides that adoption of any portion of such market practice is not administratively feasible or if the Company (or its Designee) determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company (or its Designee) determines is reasonably necessary or practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(1)in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

(2)in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1)a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such

statement or publication, there is no successor administrator that will continue to provide the Benchmark;

(2)a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

(3)a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

    A - 12

DB1/ 138804239.3

In order for a Security of this series to be repaid at the option of a Holder, the Trustee must receive, at least thirty (30) but not more than sixty (60) days before the Repayment Date,

(1)    the Security of this series with the form entitled “Option to Elect Repayment” on the reverse of the Security of this series duly completed or

(2)    a facsimile transmission or a letter from a member of a national securities exchange or a member of the Financial Industry Regulatory Authority, Inc. or a commercial bank or trust company in the United States which must set forth:

•the name of the Holder of the Security of this series;

•the principal amount of the Security of this series;

•the principal amount of the Security of this series to be repaid;

•the certificate number or a description of the tenor and terms of the Security of this series; and

•a statement that the option to elect repayment is being exercised and a guarantee that the Security of this series to be repaid, together with the duly completed form entitled “Option to Elect Repayment” on the reverse of the Security of this series, will be received by the Trustee not later than the fifth Business Day after the date of that facsimile transmission or letter.

The repayment option may be exercised by the Holder of a Security of this series for less than the entire principal amount of the Security of this series but, in that event, the principal amount of the Security of this series remaining Outstanding after repayment must be in an authorized denomination.

Conditional Right to Shorten Maturity.

If a Tax Event (as defined below) occurs, the Company will have the right to shorten the Maturity (as defined below) of the Securities of this series to a new date (the “New Maturity Date”), without the consent of the Holders of the Securities of this series,

•to the minimum extent required, in the opinion of nationally recognized independent tax counsel, so that, after shortening the Maturity, interest paid on the Securities of this series will be deductible for United States federal income tax purposes or

•if that counsel cannot opine definitively as to such a minimum period, the minimum extent so required to maintain the Company’s interest deduction,

in each case, to the extent deductible under current law, as determined in good faith by the Board of Directors, after receipt of an opinion of that counsel regarding the applicable legal standards. In that case, the amount payable on the Securities of this series on the New Maturity Date will be equal to 100% of the principal amount of the Securities of this series plus accrued and unpaid interest, if any, on the Securities of this series to but excluding the New Maturity Date. If the

    A - 13

DB1/ 138804239.3

Company elects to exercise its right to shorten the Maturity of the Securities of this series when a Tax Event occurs, the Company will give notice to each Holder of Securities of this series not more than sixty (60) days after the occurrence of the Tax Event, stating the New Maturity Date of the Securities of this series. As used herein, the term “Maturity” means the Stated Maturity Date or the New Maturity Date, as the case may be.

“Tax Event” means that the Company shall have received an opinion of nationally recognized independent tax counsel to the effect that, as a result of:

•any amendment to, clarification of, or change (including any announced prospective amendment, clarification or change) in any law, or any regulation thereunder, of the United States;

•any judicial decision, official administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an “administrative or judicial action”); or

•any amendment to, clarification of, or change in any official position with respect to, or any interpretation of, an administrative or judicial action or a law or regulation of the United States that differs from the previously generally accepted position or interpretation,

in each case, occurring on or after June 15, 2023, there is more than an insubstantial increase in the risk that interest paid by the Company on the Securities of this series is not, or will not be, deductible, in whole or in part, by the Company for United States federal income tax purposes.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture, including the Officer’s Certificate described above.

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 by such amendment to 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 all series to be thus affected. The Indenture also contains provisions permitting the Holders of specified percentages 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 compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by Holders of the specified percentages in principal amount of the Securities of this series shall be conclusive and binding upon all current and 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.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for sixty (60) days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

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 any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $1,000 and integral multiples 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 and of like tenor and of authorized denominations, as requested by the Holder surrendering the same.

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 that may be imposed in connection therewith.

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 absolute owner hereof for all purposes, whether or not this Security be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.
