Except as expressly amended by the Supplemental Indenture, the terms and provisions of the Base Indenture shall remain in full force and effect. Notwithstanding the foregoing, this Supplemental Indenture shall only apply to the Notes.

(ii)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

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

in respect of the following indebtedness of the Company, whether any such indebtedness exists as of the date of the Indenture or is created, incurred or assumed after such date: (i) all obligations for borrowed money; (ii) all obligations evidenced by debentures, debt securities or other similar instruments; (iii) all obligations in respect of letters of credit, security purchase facilities or bankers acceptances or similar instruments (or reimbursement obligations with respect thereto); (iv) all obligations to pay the deferred purchase price of property or services, except trade accounts payable arising in the ordinary course of business; (v) indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on property owned by the Company; (vi) obligations associated with derivative products including, but not limited to, interest rate and currency future or exchange contracts, foreign exchange contracts, swap agreements (including interest rate and foreign exchange rate swap agreements), cap agreements, floor agreements, collar agreements, options, interest rate future or option contracts, commodity contracts, and similar arrangements; (vii) purchase money and similar obligations; (viii) obligations to general creditors of the Company; (ix) a deferred obligation of, or any such obligation, directly or indirectly guaranteed by, the Company which obligation is incurred in connection with the acquisition of any business, properties or assets not evidenced by a note or similar instrument given in connection therewith; (x) interest or obligations in respect of any of the foregoing accruing after the commencement of insolvency or bankruptcy proceedings; (xi) all obligations of the type referred to in the foregoing subclauses above of other persons or entities for the payment of which the Company is responsible or liable as obligor, guarantor or otherwise, whether or not classified as a liability on a balance sheet prepared in accordance with GAAP; and (xii) any renewals, amendments, deferrals, supplements, extensions, refundings or replacements of any of the foregoing.

“Term SOFR” means the forward-looking term rate for the applicable Corresponding Tenor based on SOFR that has been selected or recommended by the Relevant Governmental Body.

“i” is a series of whole numbers from one to d₀, each representing the relevant U.S. Government Securities Business Days in chronological order from, and including, the first U.S. Government Securities Business Day in the relevant Observation Period.

“SOFRi”, for any U.S. Government Securities Business Day “i” in the relevant Observation Period, is equal to SOFR in respect of that day “i”.

“ni”, for any U.S. Government Securities Business Day “i” in the relevant Observation Period, is the number of calendar days from, and including, such U.S. Government Securities Business Day “i” to, but excluding, the following U.S. Government Securities Business Day (“i+1”).

“(g) in the event of an appointment of a Custodian for the Company’s Material Subsidiary.”

“If an Event of Default under clause (d), (e) or (g) of Section 501 occurs and is continuing, then the principal amount of all the Notes, together with premium, if any, and accrued and unpaid interest, if any, thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. The Maturity of the Notes shall not otherwise be accelerated as a result of an Event of Default.”

“Not in limitation of the foregoing, without the consent of any Holder of Securities, the Company and the Trustee may amend or supplement the Indenture or the Notes (i) to conform the terms of the Indenture and the Notes to the “Description of the Notes” section in the prospectus supplement, dated June 13, 2025, relating to the offering of the Notes; or (ii) to implement any benchmark transition provisions after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred (or in anticipation thereof).” The Trustee may rely on a Company Request (in addition to any other orders, certificates and opinion) as to whether any such event in clause ‎(ii) has occurred.

The payment of the principal of and interest on all Notes (including, but not limited to, the redemption price with respect to the Notes called for redemption in accordance with ‎Section 3.02(g)) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at the date of the Indenture or thereafter incurred.

No provision of this ‎Article V shall prevent the occurrence of any Default or Event of Default hereunder.

If the Trustee receives any Payment Blockage Notice pursuant to clause ‎(b) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until (A) at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice, and (B) all scheduled payments of principal, premium, if any, and interest on the Notes that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice.

The Company may and shall resume payments on and distributions in respect of the Notes upon the earlier of:

Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or Notes, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full in cash or other payment satisfactory to the holders of

such Senior Indebtedness, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Indebtedness, before any payment is made on account of the principal of or interest on the Notes (except payments made pursuant to ‎Article V of the Base Indenture from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding- up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or Notes, to which the Holders of the Notes or the Trustee would be entitled, except for the provision of this ‎Article V, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Notes or by the Trustee under the Indenture if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution or provision therefor is made to the Holders of the Notes or to the Trustee. Whenever a distribution is to be made or a notice given to the holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative.

In the event of the acceleration of the Notes because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Notes in respect of the principal of or interest on the Notes (including, but not limited to, the redemption price with respect to the Notes called for redemption in accordance with ‎Section 3.02(g)), except payments and distributions made by the Trustee as permitted by the first or second paragraph of ‎Section 5.05, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of the Indenture. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the acceleration at the address set forth in the notice from the Agent (or successor agent) to the Trustee as being the address to which the Trustee should send its notice pursuant to this ‎Section 5.02, unless there are no payment obligations of the Company thereunder and all obligations thereunder to extend credit have been terminated or expired. In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or Notes (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Notes before all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company and directed by the Company pursuant to a Company Order, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or other payment satisfactory to the holders of such Senior

Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

Nothing contained in this ‎Article V or elsewhere in the Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness, and the Holders of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Notes the principal of (and premium, if any) and interest on the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Notes and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Note from exercising all remedies otherwise permitted by applicable law upon default under the Indenture, subject to the rights, if any, under this ‎Article V of the holders of Senior Indebtedness in respect of cash, property or Notes of the Company received upon the exercise of any such remedy.

Upon any payment or distribution of assets of the Company referred to in this ‎Article V, the Trustee, subject to the provisions of Section 601 of the Base Indenture, and the Holders of the Notes shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Notes, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this ‎Article V.

Notwithstanding anything in this ‎Article V to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 401 of the Base Indenture, and any such payment shall not be subject to the provisions of ‎Section 5.01 or ‎5.02.

The Trustee, subject to the provisions of Section 601 of the Base Indenture, shall be entitled to rely on the delivery to it of a written notice by a Representative or a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this ‎Article V, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this ‎Article V, and if such evidence is not furnished the Trustee may defer any payment to such person pending judicial determination as to the right of such person to receive such payment.

With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this ‎Article V, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into the Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 601 of the Base Indenture, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to Holders of Notes, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this ‎Article V or otherwise.

7.000% Fixed-to-Floating Rate Subordinated Notes due 2035

This Note is one of a duly authorized issue of Securities of the Company of a series designated as the “7.000% Fixed-to-Floating Rate Subordinated Notes due 2035” (herein called the “Notes”) initially issued in an aggregate principal amount of $350,000,000 on June 13, 2025. Such series of Securities has been established pursuant to, and is one of an indefinite number of series of subordinated debt securities of the Company issued or issuable under and pursuant to the Subordinated Debt Securities Indenture, dated as of June 13, 2025 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee), as supplemented and amended by the Supplemental Indenture between the Company and the Trustee, dated as of June 13, 2025 (the “Supplemental Indenture,” and the Base Indenture as supplemented and amended by the Supplemental Indenture, the “Indenture”), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the persons in whose names Notes are registered from time to time and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms, conditions and provisions of the Notes are those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and those set forth in this Note. To the extent that the terms, conditions and provisions of this Note modify, supplement or are inconsistent with those of the Indenture, then the terms, conditions and other provisions of this Note shall govern to the extent that such terms, conditions and other provisions of this Note are not inconsistent with the terms, conditions and provisions made part of the Indenture by reference to the Trust Indenture Act.

All capitalized terms used in this Note and not defined herein that are defined in the Indenture shall have the meanings assigned to them in the Indenture. To the extent that any capitalized term used in this Note and defined herein is also defined in the Indenture but conflicts with the definition provided in the Indenture, the definition of the capitalized term in this Note shall control.

The indebtedness of the Company evidenced by the Notes, including the principal thereof, premium, if any, and interest thereon, is, to the extent and in the manner set forth in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at the date hereof or hereafter incurred, and on the terms and subject to the terms and conditions set forth in the Indenture, and shall rank pari passu in right of payment with all other Securities and with all other unsecured subordinated indebtedness of the Company and not by its terms subordinate and subject in right of payment to the prior payment in full of debentures, notes, bonds or other evidences of indebtedness of types that include the Notes. Each Holder of this Note, by the acceptance hereof, agrees to and shall be bound by such provisions of the Indenture and authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided.

​

‌​

For purposes of this Note, and in calculating the interest to be paid during the Floating Rate Period:

During the Floating Rate Period, the index maturity (the “Index Maturity”) for the Notes shall be daily.

During the Floating Rate Period, the Base Rate shall be SOFR (compounded daily over a quarterly Observation Period in accordance with the specific formula described below). As further described below, (x) in determining the Base Rate for a U.S. Government Securities Business Day, the Base Rate generally will be the rate in respect of such day that is provided on the following U.S. Government Securities Business Day and (y) in determining the Base Rate for any other day, such as a Saturday, Sunday or holiday, the Base Rate generally will be the rate in respect of the immediately preceding U.S. Government Securities Business Day that is provided on the following U.S. Government Securities Business Day.

The “Spread” is the number of basis points (one one-hundredth of a percentage point) specified above to be added to the Base Rate for a Floating Rate Interest Payment Period. The amount of interest accrued and payable on the Notes for the Floating Rate Interest Payment Period will be equal to the outstanding principal amount of the Notes multiplied by the product of: (x) the sum of the Base Rate plus the Spread for the relevant Floating Rate Interest Payment Period, multiplied by (y) the quotient obtained by dividing the actual number of calendar days in such Floating Rate Interest Payment Period by 360.

Notwithstanding the foregoing, in no event will the interest rate payable for any Floating Rate Interest Payment Period be less than zero percent.

On the Floating Rate Interest Payment Date, accrued interest will be paid for the most recently completed Floating Rate Interest Payment Period. During the relevant Floating Rate Interest Payment Period, interest on the Notes will accrue from and including the first date in such Floating Rate Interest Payment Period, or from and including the Interest Reset Date in the case of the first Floating Rate Interest Payment Period. Interest will accrue to but excluding the next Floating Rate Interest Payment Date.

During the Floating Rate Period, the calculation agent shall notify the paying agent of each determination of the interest rate applicable to the notes promptly after the determination is made on the Floating Rate Interest Determination Date.

With respect to any Floating Rate Interest Payment Period, the “Base Rate” means the rate of return of a daily compound interest investment computed in accordance with the following formula (with the resulting percentage rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% being rounded upwards to 0.00001%):

Where:

“d₀”, for any Observation Period, is the number of U.S. Government Securities Business Days in the relevant Observation Period.

“i” is a series of whole numbers from one to d₀, each representing the relevant U.S. Government Securities Business Days in chronological order from, and including, the first U.S. Government Securities Business Day in the relevant Observation Period.

“SOFRi”, for any U.S. Government Securities Business Day “i” in the relevant Observation Period, is equal to SOFR in respect of that day “i”.

“n_i”, for any U.S. Government Securities Business Day “i” in the relevant Observation Period, is the number of calendar days from, and including, such U.S. Government Securities Business Day “i” to, but excluding, the following U.S. Government Securities Business Day (“i+1”).

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

In determining the Base Rate for a U.S. Government Securities Business Day, the Base Rate generally will be the rate in respect of such day that is

provided on the following U.S. Government Securities Business Day. In determining the Base Rate for any other day, such as a Saturday, Sunday or holiday, the Base Rate generally will be the rate in respect of the immediately preceding U.S. Government Securities Business Day that is provided on the following U.S. Government Securities Business Day.

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

In connection with the above, the following definitions apply:

“Benchmark” means SOFR with the Index Maturity specified above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR with the Index Maturity specified above or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order presented in clause (3) of the definition of “SOFR” that can be determined by the Company or its designee as of the Benchmark Replacement Date. 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.

“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:

(1)the Spread adjustment, or method for calculating or determining such Spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2)if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment;

(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.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Floating Rate Interest Payment Periods,” timing and frequency of determining rates and making payments of interest and other administrative matters) that the Company or its designee decide 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 decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably necessary).

“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:

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

“Floating Rate Interest Determination Date” means the date two U.S. Government Securities Business Days before each Floating Rate Interest Payment

Date (or, in the case of the final Floating Rate Interest Payment Period, before the Stated Maturity of the Notes).

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

“ISDA Fallback Adjustment” means the Spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

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

“Reference Time” with respect to any determination of the Benchmark means the time determined by the Company or its designee in accordance with the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Board of Governors of the Federal Reserve (the “Federal Reserve Board”) and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

If a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, any determination, decision or election that may be made by the Company or its designee pursuant to this section, including any determination with respect to a 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:

None of the Trustee, the paying agent or the 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, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant methodology applicable to such substitute or successor benchmark. In connection with the foregoing, each of the Trustee, paying agent 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 Company’s direction in connection therewith.

​

None of the Trustee, the paying agent or the calculation agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this note 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 required or contemplated by the terms of this note and reasonably required for the performance of such duties. None of the Trustee, paying agent or calculation agent shall be responsible or liable for the Company’s actions or omissions or for those of 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 or calculation agent be under any obligation to oversee or monitor the Company’s performance or that of its designee.

​

The Company will pay interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. The Company will make payments in respect of Notes in global form (including principal and interest) to the Holder thereof or a nominee of the Holder, by wire transfer of immediately available funds as of the close of business on the date such payments are due.

​

The term “Business Day” means any day that is not a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions in the City of New York or any place of payment are authorized or required by law, regulation or executive order to close.

If the Company defaults in the payment of interest due on any Interest Payment Date after taking into account any applicable grace period, such defaulted interest shall be paid as set forth in the Indenture.

The Notes are intended to be treated as Tier 2 Capital (or its then-equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy rules or regulations of the Board of Governors of the Federal Reserve System (or any successor regulatory authority with jurisdiction over bank holding companies) (the “Federal Reserve”) as applicable to the Company and as the same may be amended or supplemented from time to time. If an Event of Default with respect to Notes shall occur and be continuing, the principal and interest owed on the Notes shall only become due and payable in accordance with the terms and conditions set forth in ‎Article V of the Base Indenture and ‎Section 3.02(m) and ‎(n) of the Supplemental Indenture. Accordingly, the Holder of this Note has no right to accelerate the maturity of this Note in the event that the Company fails to pay interest on any of the Notes, or fails to perform any other obligations under the Notes or in the Indenture that are applicable to the Notes.

The Company may, at its option, redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest (the “Redemption Price”) to, but excluding, the date of redemption (the “Redemption Date”), on any Interest Payment Date on or after June 13, 2030. The Company may also, at its option, redeem the Notes before the Stated Maturity Date, in whole, but not in part, at any time, upon the occurrence of a Tier 2 Capital Event, a Tax Event or if the Company is required to register as an investment company pursuant to the Investment Company Act of 1940, as amended. Any such redemption will be at a redemption price equal to the Redemption Price to, but excluding, the Redemption Date fixed by the Company. No redemption of the Notes by the Company prior to the Stated Maturity Date shall be made without the prior approval of the Federal Reserve if such prior approval is or will be required at the scheduled Redemption Date. The provisions of Article III of the Base Indenture and ‎Section 3.02(g) of the Supplemental Indenture shall apply to the redemption of any Notes by the Company.

The Notes are not entitled to the benefit of any sinking fund. The Notes are not convertible into or exchangeable for any other securities or property of the Company or any Subsidiary of the Company.

In the event that any payment on the Notes is subject to withholding of any U.S. federal income tax or other tax or assessment (as a result of a change in law or otherwise), the Company will not pay additional amounts with respect to such tax or assessment.

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 Notes at any time by the Company and the Trustee with the consent of the Holders of at least a majority in principal amount of the outstanding Notes. The Indenture also contains provisions permitting the Holders of

specified percentages in principal amount of the Notes at the time outstanding, on behalf of the Holders of all Notes, to waive certain past Defaults 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 upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Register described in Section 305 of the Base Indenture, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note 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 Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

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

The Company and the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security is a global note, represented by one or more permanent global certificates registered in the name of the nominee of The Depository Trust Company (each a “Global Note” and collectively, the “Global Notes”). Accordingly, unless and until it is exchanged for individual certificates, this Note may not be transferred except as a whole by The Depository Trust Company (the “Depositary”) to a nominee of such Depositary or by a nominee of such Depositary or by the Depositary or any nominee to a successor Depositary or any nominee of such successor. Ownership of beneficial interests in this Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the applicable Depositary or its nominee (with respect to interest of persons that have accounts with the Depositary (“Participants”)) and the records of Participants (with respect to interests of persons other than Participants). Beneficial interests in Notes owned by persons that hold through Participants will be evidenced only by, and transfers of such beneficial interests with such Participants will be effected only through, records maintained by such Participants. Except as provided below, owners of beneficial interests in this Note will not be entitled to have any individual certificates and will not be considered the owners or Holders thereof under the Indenture.

​

Except in the limited circumstances set forth in the Base Indenture, Participants and owners of beneficial interests in the Global Notes will not be entitled to receive Notes in the form of Individual Securities and will not be considered Holders of Notes. None of the Company, the Trustee, the Security Registrar, the Paying Agent or any of their respective agents will be liable for any delay by the Depositary, its nominee or any direct or indirect Participant in identifying the beneficial owners of the related Notes. The Company, the Trustee, the Security Registrar, the Paying Agent and each of their respective agents may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the Notes to be issued.

Except as provided in Section 305 of the Base Indenture and ‎Section 3.02(f) of the Supplemental Indenture, beneficial owners of Global Notes will not be entitled to receive physical delivery of Notes in the form of Individual Securities, and no Global Note will be exchangeable except for another Global Note of like denomination and tenor to be registered in the name of the Depositary or its nominee. Accordingly, each person owning a beneficial interest in a Global Note must rely on the procedures of the Depositary and, if such person is not a Participant, on the procedures of the Participant through which such person owns its interest, to exercise any rights of a Holder under the Notes.

The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the Notes represented by a Global Note to those persons may be limited. In addition, because the Depositary can act only on behalf of its Participants, who in turn act on behalf of persons who hold interests through Participants, the ability of a person having an interest in Notes represented by a Global Note to pledge or transfer such interest to persons or entities that do not participate in the Depositary’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest. None of the Company, the Trustee, the Paying Agent and the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of Notes by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to the Notes.

The Trustee will act as the Company’s Paying Agent with respect to the Notes through its Corporate Trust Office presently located at One Federal Street, 3rd Floor, Boston MA 02110. The Company may at any time rescind the designation of a Paying Agent, appoint a successor Paying Agent, or approve a change in the office through which any Paying Agent acts.

Notices to the Holders of registered Notes in the form of Individual Securities will be given to such Holders at their respective addresses in the Register, or in the case of Global Notes, electronic delivery in accordance with DTC’s applicable procedures. The Indenture contains provisions setting forth certain conditions to the institution of

proceedings by the Holders of Notes with respect to the Indenture or for any remedy under the Indenture.

THIS NOTE IS GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.
