If the Company is unable to appoint an independent financial advisor, or the independent financial advisor appointed by the Company fails to determine an appropriate substitute reference rate, then the Company (in consultation with the Calculation Agent to the extent practicable and acting in good faith) may determine a substitute reference rate for purposes of determining the rate of interest for the applicable Interest Period; provided, however, that if the Company is unable or unwilling to determine a substitute reference rate prior to a LIBOR Determination Date in accordance with the immediately preceding clause, the rate of interest will be equal to the rate of interest in effect with respect to the immediately preceding LIBOR Determination Date or, in the case of the initial LIBOR Determination Date, the rate of interest will be equal to the Fixed Interest Rate.

GENERAL TERMS AND CONDITIONS OF THE NOTES

Section 201 Terms of Notes.

Pursuant to Sections 201 and 301 of the Base Indenture, there is hereby established a series of Securities, the terms of which shall be as follows:

(a) Designation. The Notes shall be known and designated as the “5.25% Fixed to Floating Rate Subordinated Notes due 2028”. The CUSIP number for the Notes is 064227 AB7. The Notes shall be issued in minimum denominations of $1,000 and any integral multiple thereof. The Notes shall not be issued as Original Issue Discount Securities.

(b) Aggregate Principal Amount. The maximum aggregate principal amount of the Notes that may be authenticated and delivered under this Supplemental Indenture is initially limited to $75,000,000 (except for Notes authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306, 906 or 1107 of the Base Indenture). The Company may, without the consent of the Holders of the Notes, issue additional notes of this series in an unlimited amount having the same ranking, Stated Maturity, CUSIP number and terms as to status, redemption or otherwise as the Notes (other than dates as to issuance and the initial accrual of interest), in which event such notes and the Notes shall constitute one series for all purposes under the Indenture, including without limitation, amendments, waivers and redemptions; provided, that if any such additional notes are not fungible with the Notes for United States federal income tax purposes, such additional notes will have a separate CUSIP or other identifying number.

(c) Form and Denomination. The Notes will be issued in book-entry form, and the minimum authorized denominations of the Notes shall be $1,000 principal amount and integral multiples of $1,000 in excess thereof. The Notes will initially be issued in the form of one or more Global Securities substantially in the form of Exhibit A (attached hereto), with such modifications thereto as may be approved by the authorized officer executing the same. The Notes will be denominated in U.S. Dollars and payments of principal and interest will be made in U.S. Dollars.

Upon their original issuance, the Notes shall be issued in the form of Global Securities registered in the name of the Depositary or its nominee and deposited with the Trustee, as custodian for the Depositary, for credit by the Depositary to the respective accounts of beneficial owners of the Notes represented thereby (or such other accounts as they may direct). Each such Global Security will constitute a single Security for all purposes of the Indenture.

(d) Stated Maturity. The principal amount of, and all accrued and unpaid interest (including compounded interest) on, the Outstanding Notes shall be payable in full on June 1, 2028, or if such day is not a Business Day, the next Business Day (the “Stated Maturity”).

(e) Rate of Interest. The Notes shall bear interest on their principal amount (i) from and including May 24, 2018, to, but excluding June 1, 2023, at the rate of 5.25% per annum, computed on the basis of a 360-day year comprised of twelve 30-day months (the “Fixed Interest Rate”), and (ii) from and including June 1, 2023, to, but excluding the Stated Maturity or earlier Redemption Date, at a floating per annum rate equal to the Three-month LIBOR (provided, however, that in the event that the Three-month LIBOR is less than zero, the Three-month LIBOR shall be deemed to be zero) plus a spread of 225.5 basis points, computed on the basis of a 360-day year and the actual number of days elapsed. All percentages resulting from any calculation of the Three-month LIBOR will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. All amounts used in or resulting from any calculation will be rounded upward or downward as appropriate, to the nearest cent with one-half cent or more being rounded upward. In the case of Section 201(e)(i), interest on the Notes shall be payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2018 and ending on June 1, 2023 (each such date, a “Fixed-Rate Interest Payment Date”) and in the case of Section 201(e)(ii), interest on the Notes shall be payable quarterly in arrears on March 1, June 1,September 1 and December 1 of each year, beginning on September 1, 2023 (each such date, a “Floating-Rate Interest Payment Date”). In the event any Fixed-Rate Interest Payment Date falls on a day that is not a Business Day, the interest payment due on that date will be postponed to the next day that is a Business Day and no interest shall accrue as a result of such postponement. If any Floating-Rate Interest Payment Date would otherwise fall on a day that is not a Business Day, such Floating-Rate Interest Payment Date will be postponed to the following Business Day and interest will accrue to the actual Floating-Rate Interest Payment Date, unless such postponement would cause the day to fall in the next calendar month, in which case it shall be brought forward to the immediately preceding Business Day.

(f) To Whom Interest is Payable. Interest shall be payable to the Person in whose name the Notes are registered at the close of business on the Business Day next preceding the Interest Payment Date, or in the event the Notes cease to be held in the form of one or more Global Securities, at the close of business on the date 15 days prior to that Interest Payment Date, whether or not a Business Day.

(g) Acceleration of Maturity. If an Event of Default specified in Section 501(a) of the Base Indenture occurs, then, in every such case, the principal amount of (and premium, if any, on) and accrued interest on all the Outstanding Notes shall automatically become due and payable immediately, without any declaration or other action on the part of the Trustee or any Holder.

If any deduction or withholding for any present or future taxes, duties, assessments or other governmental charges of the Relevant Taxing Jurisdiction shall at any time be required by the Relevant Taxing Jurisdiction in respect of any amounts to be paid by the Company on or in respect of the Notes, the Company will pay to each Holder of Notes as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amounts paid to each such Holder, after such deduction or withholding (and after deducting taxes on such Additional Amounts), shall be not less than the amounts such Holder would have received if such taxes, duties, assessments or other governmental charges had not been withheld or deducted; provided, however, that the Company shall not be required to make any payment of Additional Amounts for, or on account of, any:

(a) present or future tax, duty, assessment or other governmental charge which would not have been imposed but for (a) the existence of a present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, such Holder, if such Holder is an estate, trust, partnership or corporation) and the Relevant Taxing Jurisdiction, as the case may be, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a domiciliary, national or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or otherwise having or having had some connection with the Relevant Taxing Jurisdiction, as the case may be, other than the holding or ownership of a Note or the collection of principal of and interest and premium, if any, on a Note or (b) the presentation of a Note (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later, except to the extent that the Holder would have been entitled to such Additional Amounts if it had presented such Note for payment on any day within such period of 30 days;

(e) present or future tax, duty, assessment or other governmental charge required to be withheld or deducted by any paying agent from any payment on a Note if such payment can be made without such withholding or deduction by presenting the Note to (where presentation is required for payment), or otherwise accepting payment from, any other paying agent; or

(f) combination of the items above.

(ii) Notwithstanding the foregoing, all payments shall be made net of any deduction or withholding imposed or collected pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such sections of the Code (or any law implementing such an intergovernmental agreement) (any such withholding, a “FATCA Withholding Tax”), and no Additional Amounts will be payable as a result of any such FATCA Withholding Tax. No Additional Amounts be paid with respect to any payment of principal of, and any premium or interest on, any Note to any Holder who is a fiduciary, a partnership, a limited liability company or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the Relevant Taxing Jurisdiction to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary, a member of such partnership, an interest holder in a limited liability company or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder of such Note.

(iii) Wherever in the Indenture there is mentioned, in any context, the payment of principal of, and any premium or interest, if any on, or any other amount payable under or with respect to the Notes, such mention will be deemed to include payment of Additional Amounts provided for in the Indenture to the extent that in such context, Additional Amounts are, were or could be payable in respect thereof. In the event of the occurrence of any transaction or event resulting in a successor to the Company, all references to the Relevant Taxing Jurisdiction in this Supplemental Indenture shall be deemed to be references to the jurisdiction of organization or tax residence of the successor entity.

The Bank of N.T. ▇▇▇▇▇▇▇▇▇▇▇ & Son Limited, a company duly incorporated and existing under the laws of Bermuda (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of SEVENTY-FIVE MILLION DOLLARS ($75,000,000) on June 1, 2028 (or, if this day is not a Business Day, the following Business Day) (the “Stated Maturity”).

This Security shall bear interest (i) from and including May 24, 2018, to, but excluding June 1, 2023, payable at the rate of 5.25% per annum semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2018 and ending on June 1, 2023 (computed on the basis of a 360-day year comprised of twelve 30-day months), and (ii) from and including June 1, 2023, at an annual rate equal to the Three-month LIBOR (as defined in the Indenture) plus 2.255% (computed on the basis of a 360-day year and the actual number of days elapsed), payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year, beginning on September 1, 2023, until the principal hereof is paid or made available for payment (each such date referred to in clause (i), a “Fixed-Rate Interest Payment Date”, and each such date referred to in clause (ii), a “Floating-Rate Interest Payment Date”). In the event that any Fixed-Rate Interest Payment Date falls on a day that is not a Business Day, the interest payment due on that date shall be postponed to the next day that is a Business Day and no interest shall accrue as a result of that postponement. In the event that any Floating-Rate Interest Payment Date would otherwise fall on a day that is not a Business Day, that Floating-Rate Interest Payment Date shall be postponed to the next day that is a Business Day and interest will accrue to the actual Floating-Rate Interest Payment Date, unless such postponement would cause the day to fall in the next calendar month, in which case it shall be brought forward to the immediately preceding Business Day.

A “Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to close.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be (i) the Business Day immediately preceding the Interest Payment Date if this Security is issued in the form of a Global Security, or (ii) the day 15 days prior to that Interest Payment Date (whether or not a Business Day), if this Security is not issued in the form of a Global Security. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of (and premium, if any) and any such interest on this Security shall be made 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 and such payment shall be made through one or more Paying Agents appointed under the Indenture to the Holders of this Security; provided, however, that at the option of the Company payment of interest will be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer in immediately available funds at such place and to such account as may be designated by the Person entitled thereto as specified in the Security Register; provided, further, that any such payment and any such interest on the Securities beneficially held that are represented by this Global Security, and all transfers and deliveries of such Securities shall be made to the Depositary, which shall initially be the Depository Trust Company, or its nominee, as the case may be, as the Holder of this Global Security, in accordance with the Depositary’s procedures.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

In Witness Whereof, the Company has caused this instrument to be duly executed under its corporate seal.

[Reverse of Security]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in one or more series under a Subordinated Debt Securities Indenture, dated as of May 24, 2018 (herein called the “Base Indenture”, which term shall have the meaning assigned to it in such instrument), as supplemented by a First Supplemental Indenture, dated as of May 24, 2018, (herein called the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), in each case, between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $75,000,000 (except for Notes authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306, 906 or 1107 of the Base Indenture).

All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Notes shall be redeemable in accordance with Article Eleven of the Base Indenture, provided that the Notes shall be redeemable at the Company’s option, (1) at any time on or after June 1, 2023, in whole or in part; and (2) at any time prior to June 1, 2023, in whole, but not in part, within 90 days after the occurrence of a Tax Event, a Tier 2 Capital Event or a 1940 Act Event, in each case of (1) and (2), at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest to but excluding the Redemption Date. Any such redemption will be subject to the prior approval of the BMA.

In the event of redemption of Notes in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee as his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter created, incurred, assumed or guaranteed, and waives reliance by each such holder of Senior Indebtedness upon said provisions.

The Notes of this series do not have the benefit of any sinking fund obligation and are not subject to the repurchase at the option of the Holders.

The Indenture contains provisions for defeasance of the entire indebtedness of this Security at any time prior to the Stated Maturity upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes 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 the Holder of this Security shall be conclusive and binding upon such Holder and upon all 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 Notes of this series, the Holders of not less than 25% in principal amount of the Notes of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 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.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company maintained under Section 1002 of the Indenture for such purpose, 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 this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for a like aggregate principal amount of Notes of this series and of like tenor of a different authorized denomination, 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 payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, 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 owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York.
