12

or any securities exchange on which the debt securities or any class of securities of SMFG, or any successor to any of the foregoing, is listed); provided that SMFG shall not be obligated to furnish or deliver any such documents that are available to the public on SMFG’s internet website or which SMFG would be prohibited from so furnishing or delivering due to applicable laws or regulations;

(p) SMFG shall cooperate with the Underwriters to cause the debt securities to be eligible for clearance and settlement through DTC, Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”).

6.

(a) (i) SMFG represents and agrees that, (A) other than the final term sheet prepared and filed pursuant to Section 5(a) hereof, without the prior consent of the Representative(s), it has not made and will not make any offer relating to the debt securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act and (B) it has not made and will not make any offer relating to the debt securities using a written communication not required to be filed with the Commission in reliance on the exemption of Rule 163B under the Securities Act;

8. The obligations of the Underwriters hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of SMFG herein are, at and as of the Closing Time, true and correct, the condition that SMFG shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

9.

(a) SMFG will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any Pre-Offering Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that SMFG shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, the Pricing Disclosure Package, any Issuer Free Writing Prospectus, or any Pre-Offering Communication in reliance upon and in conformity with written information furnished to SMFG by any Underwriter relating to such Underwriter through the Representative(s) expressly for use therein.

(b) Each Underwriter will indemnify and hold harmless SMFG against any losses, claims, damages or liabilities to which SMFG may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any

16

Issuer Free Writing Prospectus, or any Pre-Offering Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, any Issuer Free Writing Prospectus, or any Pre-Offering Communication in reliance upon and in conformity with written information furnished to SMFG relating to any Underwriter by such Underwriter through the Representative(s) expressly for use therein; and will reimburse SMFG for any legal or other expenses reasonably incurred by SMFG in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of any counsel other than the counsel specified above or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by SMFG on the one hand and the Underwriters on the other from the offering of the debt securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of SMFG on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by SMFG on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the debt securities purchased under this Agreement (before deducting expenses) received by SMFG bear to the total underwriting discounts and commissions received by the Underwriters under this Agreement, in each case as set forth in the Underwriting Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by SMFG on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. SMFG and the Underwriters agree that it would not be just and

17

equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the debt securities underwritten by it and distributed to investors were offered to investors exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Underwriters’ obligations in this subsection (d) to contribute are several in proportions to their respective underwriting obligations and not joint.

(e) The obligations of SMFG under this Section 9 shall be in addition to any liability which SMFG may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act, and each Underwriter’s affiliates, as such term is defined in Rule 501(b) under the Securities Act, selling agents, directors, officers and agents; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of SMFG and to each person, if any, who controls SMFG within the meaning of the Securities Act.

10.

(a) If any Underwriter shall default in its obligation to purchase the debt securities which it has agreed to purchase hereunder, the Representative(s) may in their discretion arrange for them or another party or other parties to purchase such debt securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter, the Representative(s) do not arrange for the purchase of such debt securities, then SMFG shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representative(s) to purchase such debt securities on such terms. In the event that, within the respective prescribed periods, the Representative(s) notify SMFG that they have so arranged for the purchase of such debt securities, or SMFG notifies the Representative(s) that it has so arranged for the purchase of such debt securities, the Representative(s) or SMFG shall have the right to postpone the Closing Time for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and SMFG agrees to prepare promptly any amendments to the Registration Statement or the Prospectus and other documents which in the opinion of the Representative(s) may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such debt securities.

(b) If, after giving effect to any arrangements for the purchase of the debt securities of a defaulting Underwriter or Underwriters by the Representative(s) and SMFG as provided in subsection (a) above, the aggregate principal amount of such debt securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the debt securities, then SMFG shall have the right to require each non-defaulting Underwriter to purchase the aggregate principal amount of debt securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the aggregate principal amount of debt securities which such Underwriter agreed to purchase hereunder) of the debt securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the debt securities of a defaulting Underwriter or Underwriters by the Representative(s) and SMFG as provided in subsection (a) above, the

18

aggregate principal amount of such debt securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the debt securities, or if SMFG shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase debt securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or SMFG, except for the expenses to be borne by SMFG and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of SMFG and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, SMFG or any officer or director or controlling person of SMFG, as the case may be, and shall survive delivery of and payment for the debt securities.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, SMFG shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason the debt securities are not delivered by or on behalf of SMFG as provided herein, SMFG will reimburse the Underwriters through the Representative(s) for all out-of-pocket expenses approved in writing by the Representative(s), including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the debt securities, but SMFG shall then be under no further liability to any Underwriter in respect of the debt securities except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, the Representative(s) shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representative(s).

14. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Representative(s) shall be delivered or sent by mail, telex or facsimile transmission to the addresses set forth in Schedule II to the Underwriting Agreement; and if to SMFG, shall be delivered or sent by mail, telex or facsimile transmission to SMFG at the address set forth in Schedule II to the Underwriting Agreement.

15. Unless otherwise provided herein, this Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, SMFG, and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of SMFG and each person who controls SMFG or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the debt securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

16. Each of the parties hereto irrevocably (i) agrees that any legal suit, action or proceeding against SMFG brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any court of the State of New York or the United States located in the Borough of Manhattan, The City of New York (each a “New York Court”), (ii) waives, to the fullest extent it may effectively do so under applicable law, any objection which it may now or hereafter have to the laying of venue of any such proceeding in any such New York Court or any immunity it may have or hereafter acquire (on the grounds of sovereignty or otherwise) from the jurisdiction of any such New York Court or from any legal process with respect to itself or its property and (iii) submits to the non-exclusive personal jurisdiction of any such New York Court in any such suit, action or proceeding. SMFG hereby designates SMBC’s New York branch, with offices at 277 Park Avenue, New York, New York 10072, General Manager, Planning Dept., Americas Division, as SMFG’s authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any New York Court by any Underwriter or by any person who

19

controls any Underwriter, and SMFG expressly consents to the jurisdiction of any such New York Court in respect of any such action and waives any other requirements of or objections to personal jurisdiction with respect thereto. SMFG hereby agrees to maintain until the first-year anniversary of the first day upon which none of the debt securities shall be outstanding an office in The City of New York upon which process may be served in the manner contemplated in this Section 16 or, if no such office is maintained at any time, to appoint a third party with an office in The City of New York upon which such process may be served in such manner and, in connection therewith, to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent, such office of SMFG in The City of New York or such third party with an office in The City of New York, as the case may be, shall be deemed, in every respect, effective service of process upon SMFG. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, in any court of competent jurisdiction in Japan.

17. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than U.S. dollars, SMFG will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase U.S. dollars with the amount of judgment currency actually received by such Underwriter on the business day immediately following the day on which such party receives such payment. The foregoing indemnity shall constitute a separate and independent obligation of SMFG and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into U.S. dollars.

18. Time shall be of the essence of this Agreement.

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

20.

(a) SMFG acknowledges and agrees that (i) the purchase and sale of the debt securities pursuant to this Agreement is an arm’s-length commercial transaction between SMFG, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of SMFG, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of SMFG with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising SMFG on other matters) or any other obligation to SMFG except the obligations expressly set forth in this Agreement and (iv) SMFG has consulted its own legal and financial advisors to the extent it deemed appropriate. SMFG agrees that it will not claim that the Underwriters, or any of them, owes a fiduciary or similar duty to SMFG, in connection with such transaction or the process leading thereto. Nothing in this paragraph shall exclude or restrict any duty or liability of the Underwriters which they have under the Financial Services and Markets Act 2000 of the United Kingdom or the arrangements for regulating the Underwriters thereunder to any extent prohibited by those arrangements.

(b) SMFG AND EACH OF THE UNDERWRITERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

[Name(s) of Representative(s)]

As representative(s) of the several Underwriters named in Schedule I hereto

c/o [                ]

Ladies and Gentlemen:

Sumitomo Mitsui Financial Group, Inc., a joint stock company incorporated under the laws of Japan (“SMFG”), proposes, subject to the terms and conditions stated herein, to issue and sell to the underwriters named in Schedule I hereto (collectively, the “Underwriters”, and each, individually, an “Underwriter”), acting severally and not jointly, for whom [insert name(s) of Representative(s)] are acting as representatives (in such capacity, the “Representative(s)”), $[            ] aggregate principal amount of SMFG’s [[        ]%] [floating rate] [bonds/notes] (the “[Bonds/Notes]”) having the terms set forth in Schedule II hereto. The [Bonds/Notes] are to be issued pursuant to an indenture dated as of [            ], 20[    ] (the “Indenture”) between SMFG and [insert name of Trustee], as trustee (the “Trustee”). With respect to the offering, issue and purchase of the [Bonds/Notes], the term “Applicable Time” in the Underwriting Agreement Standard Provisions (as defined below) shall be deemed to refer to [            ] [a.m./p.m.] (New York City time) on [            ], 20[    ]. The [Bonds/Notes] are “debt securities” referred to in the document entitled Sumitomo Mitsui Financial Group, Inc. Debt Securities Underwriting Agreement Standard Provisions (the “Underwriting Agreement Standard Provisions”) attached hereto as Annex A. All capitalized terms used but not defined herein shall have the meaning given to them in the Underwriting Agreement Standard Provisions attached hereto.

1. Subject to the terms and conditions herein set forth or herein incorporated by reference, SMFG agrees to issue and sell to each of the Underwriters and each of the Underwriters agrees, severally and not jointly, to purchase from SMFG, at a purchase price of [        ]% of the aggregate principal amount of the [Bonds/Notes], the respective principal amount of the [Bonds/Notes] as set forth opposite the name of such Underwriter in Schedule I hereto. In each case, the purchase price will be plus accrued interest from [            ], 20[    ], if settlement occurs after that date.

2. SMFG covenants and agrees to pay or cause to be paid to [insert name of Representative] for the account of the Underwriters and as compensation for the Underwriters’ commitments hereunder and for the Underwriters’ services in connection with the procuring of subscribers for or purchase of the [Bonds/Notes] and the management of the offering thereof, if the sale and delivery of the [Bonds/Notes] to the Underwriters provided herein is consummated as contemplated hereby, an amount equal to [        ]% of the principal amount of the [Bonds/Notes], which may be divided among the Underwriters in such proportions as the Underwriters may determine.

3. SMFG understands that the Underwriters intend to make a public offering of the [Bonds/Notes] as soon after the effectiveness of this Underwriting Agreement as in the judgment of the Representative(s) is advisable, and initially to offer the [Bonds/Notes] on the terms set forth in the Pricing Disclosure Package and the Prospectus. Schedule III hereto sets forth the Pricing Disclosure Package, any materials deemed to be an Issuer Free Writing Prospectus and any Pre-Offering Communication for the purpose of this Underwriting Agreement. SMFG acknowledges and agrees that the Underwriters may offer and sell [Bonds/Notes] to or through any affiliate of an Underwriter and that any such affiliate may offer and sell [Bonds/Notes] purchased by it to or through any Underwriter.

4. Payment of the purchase price for and delivery of the [Bonds/Notes] shall be made at [            ] [a.m./p.m.], New York City time, on [            ], 20[    ] or such other time and date as the Representative(s) and SMFG may agree upon in writing. Payment of the purchase price for the [Bonds/Notes] shall be made by [insert name of Representative], on behalf of the Underwriters, by wire transfer of immediately available funds to the account designated by SMFG in U.S. dollars. The [Bonds/Notes] to be purchased by each Underwriter hereunder will be issued in book-entry form and will be deposited by or on behalf of SMFG with The Depository Trust Company (“DTC”) or its custodian. SMFG will deliver the [Bonds/Notes] to [insert name of Representative], for the account of each Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor as set forth in the first sentence of this paragraph, by causing DTC to credit the [Bonds/Notes] to the accounts designated by [insert name of Representative] at DTC.

5. It is understood that each Underwriter has authorized the Representative(s), for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the [Bonds/Notes] which it has agreed to purchase. [insert name of Representative] or its agent, individually and not as Representative, may (but shall not be obligated to) make payment of the purchase price for the [Bonds/Notes] to be purchased by any Underwriter whose funds have not been received by the Closing Time, but such payment shall not relieve such Underwriter from its obligations hereunder.

6. During the period beginning from the date of this Underwriting Agreement and continuing until the Closing Time, SMFG agrees with each of the Underwriters not to directly or indirectly issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise transfer or dispose of, in any market outside of Japan, any [senior]/[subordinated] debt securities of SMFG which are denominated in U.S. dollars without the prior written consent of the Underwriters.
