The semiannual interest to be paid on the Securities will amount to U.S.$29.04 per U.S.$1,000 in nominal amount of the Securities.

For the purposes of this Security, the term “Business Day” means any day which is not a day on which banking institutions in The City of New York, London or Tokyo are authorized or required by law, regulation 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 the Indenture, be paid to the person in whose name this Security is registered as of the close of business on the fifteenth day before the Interest Payment Date (whether or not a Business Day).

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any payment is due on the Securities on a day that is not a Business Day, payment will be made on the day that is the next succeeding Business Day without any additional interest as a result of such delay. Payments postponed to the next Business Day in this situation will be treated under the Indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the Securities or the Indenture, and no interest will accrue on the postponed amount from the original due date to the next succeeding day that is a Business Day.

The principal of, and interest and Additional Amounts on, the Securities will be payable in U.S. dollars. The Issuer will cause the Trustee, or the paying agent, if any, to pay such amounts, on the dates payment is to be made, directly to The Depository Trust Company (“DTC”).

The Issuer will pay the Holder hereof Additional Amounts with respect to withholding taxes as are provided for, and subject to the conditions stated, on the reverse of this Security.

This Security is being deposited with DTC acting as depository, and registered in the name of Cede & Co., a nominee of DTC. As Holder of record of this Security, Cede & Co. shall be entitled to receive payments of principal and interest. Payments of principal and interest, including any Additional Amounts, on this Security shall be made in the manner specified on the reverse hereof and, to the extent not inconsistent with the provisions set forth herein, in the Indenture referred herein.

The Securities constitute the direct, unconditional, unsecured and unsubordinated general obligations of the Issuer and shall at all times rank pari passu without any preference among themselves and with all other unsecured obligations of the Issuer, other than subordinated obligations of the Issuer and except for statutorily preferred obligations. The Securities are not redeemable prior to maturity, except as set forth on the reverse of this Security and will not be subject to any sinking fund.

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.

5.808% Senior Notes due 2033

This Security is one of a duly authorized issue of unsecured bonds, debentures, notes or other evidences of indebtedness of Sumitomo Mitsui Financial Group, Inc., a joint stock company (kabushiki kaisha) organized under the laws of Japan (herein called the “Issuer”, which term includes any successor person under the Indenture hereinafter referred) designated as its 5.808% Senior Notes due 2033 (herein called the “Securities”), issued under and pursuant to a senior indenture dated as of March 9, 2016, as supplemented by the First Supplemental Indenture dated as of July 16, 2019 (hereinafter called the “Indenture”), between the Issuer and The Bank of New York Mellon, as trustee (herein called the “Trustee”, which term includes any successor trustee under 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, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any paying agent, the Issuer and the Holders of the Securities and of the terms upon which the Securities are issued and are to be authenticated and delivered.

This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary as to denomination, date, amount, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount.

The principal of and interest (and any Additional Amounts) on the Securities shall be payable in U.S. Dollars or in such other coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. So long as any of the Securities are held in global form, payments of principal and interest on such Securities shall be made by wire transfer in immediately available funds in U.S. Dollars to a bank account in The City of New York designated by the Holder of this Registered Global Security. Otherwise, (i) the principal amount of the Securities will be payable by check, drawn on a bank in The City of New York, upon the presentation and surrender of the Securities at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose and (ii) interest on the Securities will be payable by check, drawn on a bank in The City of New York, mailed to the persons in whose names the Securities are registered as of the close of business on the record date which is at least five Business Days preceding the applicable Interest Payment Date (or the subsequent record date in the case of a defaulted interest payment) at the addresses of such persons as shall appear in the Security register of the Issuer; provided, however, that at the option of a Holder in whose name at least U.S.$1,000,000 principal amount of Securities are registered, all payments in respect of the Securities may be received by wire transfer in immediately available funds to a bank account in The City of New York designated by such ▇▇▇▇▇▇ in a written notice received by the Trustee (a) in the case of an interest payment, prior to the record date which is at least five Business Days preceding the Interest Payment Date on which such payment is due and (b) in the case of payment of principal, prior to the record date which is at least five Business Days preceding the date of redemption or maturity, as the case may be; provided, however, that in the case of such a payment of principal, the Securities shall have been surrendered to the Trustee at the Corporate Trust Office of the Trustee or at any office or agency maintained by the Issuer for such purpose for payment together with such notice.

All payments of principal and interest in respect of the Securities will be made by the Issuer without withholding or deduction for or on account of any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any authority thereof or therein having power to tax (“Taxes”) unless such withholding or deduction is required by law. In such event, the Issuer shall pay to a Holder such additional amounts (“Additional Amounts”) as will result in the receipt by the Holder of such amounts as would have been received by it had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any Securities under any of the following circumstances:

No Additional Amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code and the U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted or published in any jurisdiction implementing, or relating to, FATCA or any intergovernmental agreement.

Where Securities are held through a participant of an international Clearing Organization or a financial intermediary (each, a “Participant”), in order to receive payments free of withholding or deduction by the Issuer for or on account of Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Japanese financial institution falling under certain categories prescribed by the Special Taxation Measures Act (a “Designated Financial Institution”), each such beneficial owner shall, at the time of entrusting a Participant with the custody of the relevant Securities, provide certain information prescribed by the Special Taxation Measures Act to enable the Participant to establish that such beneficial owner is exempted from the requirement for withholding or deduction of such Taxes (“Interest Recipient Information”), and advise the Participant if the beneficial owner ceases to be so exempted (including the case in which a beneficial owner who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of the Issuer).

Where Securities are not held through a Participant, in order to receive payments free of withholding or deduction by the Issuer for, or on account of, Taxes, if the relevant beneficial owner is (A) an individual non-resident of Japan or a non-Japanese corporation (other than a specially-related person of the Issuer) or (B) a Designated Financial Institution, each such beneficial owner shall, prior to each time at which it receives interest, submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho) (a “Tax Exemption Application”), in a form obtainable from the paying agent stating, inter alia, the name and address (and, if applicable, the Japanese individual or corporation ID number) of the beneficial owner, the title of the Securities, the relevant Interest Payment Date, the amount of interest and the fact that the beneficial owner is qualified to submit the Tax Exemption Application, together with documentary evidence regarding its identity and residence.

By subscribing to the Securities as part of the distribution by the underwriters under the applicable underwriting agreement, an investor shall be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the Issuer or (ii) a Designated Financial Institution.

The Issuer shall make any required withholding or deduction and remit the full amount withheld or deducted to the Japanese taxing authority in accordance with applicable law. The Issuer shall use reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any tax, duty, assessment, fee or other governmental charge so withheld or deducted from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge, and if certified copies are not available, the Issuer shall use reasonable efforts to obtain other evidence satisfactory to the Trustee, and the Trustee shall make such certified copies or other evidence available to the Holders upon reasonable request to the Trustee.

If (i) subsequent to making a payment on this Security without withholding or deduction of Japanese taxes the Issuer is required to remit to the Japanese taxing authority any amount in respect of Japanese taxes that should have been withheld or deducted from such payment (together with any interest and penalties) due to the failure of the beneficial owner to provide accurate Interest Recipient Information or to otherwise properly claim an exemption from Japanese taxes imposed with respect to such payment, and (ii) such beneficial owner would not have been entitled to receive Additional Amounts with respect to such payment had Japanese taxes been withheld from the payment when it was made, such beneficial owner (but not any subsequent beneficial owner of such Security) shall be required to reimburse the Issuer, in Japanese yen, for the amount remitted by the Issuer to the Japanese taxing authority.

The obligation to pay Additional Amounts with respect to any taxes, duties, assessments or other governmental charges shall not apply to (A) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by withholding or deduction from payments of principal of or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Issuer shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or similar levies and other duties, if any, which may be imposed by Japan, the United States or any political subdivision or any taxing authority thereof or therein, with respect to the execution and enforcement of the Indenture or as a consequence of the initial issuance, execution, delivery or registration of this Security.

The Securities may be redeemed at the option of the Issuer, in whole, but not in part, subject to prior confirmation of the FSA, if such confirmation is required under applicable Japanese laws or regulations then in effect, at any time, on giving not less than 30 nor more than 60 days’ notice of redemption to the Holders of the series to be redeemed (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of the Securities together with any accrued and unpaid interest (including Additional Amounts with respect thereto, if any) to (but excluding) the date fixed for redemption, if the Issuer is or will be obliged to pay Additional Amounts as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the issuance of the relevant series of Securities and such obligation cannot be avoided by the Issuer through the taking of reasonable measures available to the Issuer; provided, that no such notice of redemption shall be given sooner than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment then due in respect of the relevant Securities.

Notwithstanding anything to the contrary in the Indenture or the Securities, each Holder and the Trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer, not to initiate any action to attach any of the Issuer’s assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act, and (b) to any transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act, including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of the Issuer’s assets under Article 126-5 of the Deposit Insurance Act, and that any such transfer shall not constitute a sale or disposal of the Issuer’s properties or assets for the purpose of Article 8 of the Indenture.

Subject to applicable law, each Holder of Securities, by acceptance of any interest in the Securities, agrees that it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by the Issuer arising under, or in connection with, the Securities or the Indenture.

The Issuer shall, as soon as practicable after the Prime Minister of Japan has confirmed that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to the Issuer or a Japanese court has publicly announced that it has granted permission to a transfer of the Issuer’s assets (including shares of the Issuer’s subsidiaries) or liabilities, or any portions thereof, in accordance with Article 126-13 of the Deposit Insurance Act, deliver a written notice of such event to the Holders and beneficial owners of the Securities through DTC and to the Trustee. Any failure or delay by the Issuer to provide such written notice shall not change or delay the effect of the acknowledgement, consent and agreement described in the preceding paragraph.

A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the face of this global Security, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be included on the face of any Securities issued in definitive form. The security registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate 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 Issuer 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 the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Issuer in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities 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 Securities of this series are issuable only in registered form without coupons in denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess 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 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; provided, however, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name this Security is registered upon the Security register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer nor the Trustee nor any such agent shall be affected by notice to the contrary.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, as herein prescribed.

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

All capitalized terms used and not defined herein shall have the meanings assigned to them in the Indenture.
