Ladies and Gentlemen:

We have acted as U.S. counsel to Canadian Imperial Bank of Commerce, a Canadian bank amalgamated under and governed by the *Bank Act* (Canada) ("CIBC"), in connection with the issuance and sale of US$650,000,000 aggregate principal amount of its Floating Rate Senior Notes due 2028, US$850,000,000 aggregate principal amount of its 4.243% Fixed-to-Floating Rate Senior Notes due 2028 and US$1,000,000,000 aggregate principal amount of its 4.580% Fixed-to-Floating Rate Senior Notes due 2031 (collectively, the "Securities"), pursuant to a registration statement on Form F-3 (File No. 333-282307) (the "Registration Statement"), including the prospectus constituting a part thereof, dated October 2, 2024 (the "Base Prospectus"), and the prospectus supplement, dated September 2, 2025 (the "Prospectus Supplement" and together with the "Base Prospectus," the "Prospectus"), filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"). The Securities are being issued under an indenture, dated as of September 14, 2010 (the "Base Indenture"), between CIBC and The Bank of New York Mellon (the "Trustee"), as supplemented by the First Supplemental Indenture, dated as of April 2, 2019, and the Second Supplemental Indenture, dated as of September 11, 2024 (the Base Indenture, as so supplemented, the "Indenture").

In connection with our representation, we have examined (i) the Registration Statement, (ii) the Prospectus, (iii) an executed copy of the Indenture, (iv) the forms of certificates representing the Securities and (v) the corporate records of the Company, including its certificate of incorporation, bylaws and other corporate records and documents and have made such other examinations as we consider necessary to render this opinion. In rendering this opinion, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to the original documents of all documents submitted to us as certified, conformed or photostatic copies. As to all parties, we have assumed the legal competence of each individual executing any document, the due authorization, execution and delivery of all documents and the validity and enforceability thereof against all parties thereto, other than CIBC, in accordance with their respective terms. As to matters of fact (but not as to legal conclusions), to the extent we deemed proper, we have relied on statements and representations of responsible officers and other representatives of CIBC and of public officials.

Based upon and subject to the foregoing, and having regard for legal considerations which we deem relevant, it is our opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) assuming that the Indenture has been duly authorized, executed and delivered by CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein and is a valid and legally binding obligation of CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein, the Indenture is the legal, valid and binding obligation of CIBC, enforceable against CIBC in accordance with its terms (subject, as to enforceability, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors' rights generally from time to time in effect and to general principles of equity regardless of whether enforceability is considered in a proceeding in equity or at law); *provided that* we express no opinion with respect to Section 301(b) of the Base Indenture or Section 1601(a) of the Base Indenture (as set forth in Section 2.7 of the First Supplemental Indenture), which is governed by the laws of the Province of Ontario and the federal laws of Canada; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) assuming that the Securities have been duly authorized, established, executed and delivered by CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein and are valid and legally binding obligations of CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein, when executed and authenticated by the Trustee in accordance with the terms and provisions of the Indenture, and delivered against due payment therefor as provided in the prospectus supplement, the Securities will constitute valid, binding and enforceable obligations of CIBC, entitled to the benefits of the Indenture (subject, as to enforceability, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors' rights generally from time to time in effect and to general principles of equity regardless of whether enforceability is considered in a proceeding in equity or at law); *provided that* we express no opinion with respect to Section 301(b) of the Base Indenture or Section 1601(a) of the Base Indenture (as set forth in Section 2.7 of the First Supplemental Indenture), which is governed by the laws of the Province of Ontario and the federal laws of Canada.

We are admitted to practice in the States of Illinois and New York and our opinions expressed herein are limited solely to the Federal laws of the United States of America and the laws of the States of Illinois and New York, and we express no opinion herein concerning the laws of any other jurisdiction. With respect to all matters of the laws of the Province of Ontario and the federal laws of Canada, we understand that you are relying upon the opinion, dated the date hereof, of Blake, Cassels & Graydon LLP, Canadian counsel for CIBC, and our opinion is subject to the same assumptions, qualifications and limitations with respect to such matters as are contained in such opinion of Blake, Cassels & Graydon LLP.

**Issue of US$650,000,000 Aggregate Principal Amount of Floating Rate Senior Notes due 2028, US$850,000,000 Aggregate Principal Amount of 4.243% Fixed-to-Floating Rate Senior Notes due 2028 and US$1,000,000,000 Aggregate Principal Amount of 4.580% Fixed-to-Floating Rate Senior Notes due 2031**

Dear Sirs/Mesdames:

We have acted as special Canadian counsel to Canadian Imperial Bank of Commerce (the "**Bank**") in connection with the issuance and sale of US$650,000,000 aggregate principal amount of the Bank's Floating Rate Senior Notes due 2028 (the **"Floating Rate Notes**"), US$850,000,000 aggregate principal amount of the Bank's 4.243% Fixed-to-Floating Rate Senior Notes due 2028 (the "**2028 Fixed-to-Floating Rate Notes**") and US$1,000,000,000 aggregate principal amount of the Bank's 4.580% Fixed-to-Floating Rate Senior Notes due 2031 (the "**2031 Fixed-to-Floating Rate Notes**", and, collectively with the Floating Rate Notes and the 2028 Fixed-to-Floating Rate Notes, the "**Notes**"), pursuant to an underwriting agreement dated September 2, 2025 (the "**Underwriting Agreement**"), among the Bank and CIBC World Markets Corp., BofA Securities, Inc., Citigroup Global Market Inc., BNP Paribas Securities Corp., Goldman Sachs & Co. LLC and UBS Securities LLC, as representatives of the several underwriters named in Schedule 2 thereto. The Notes will be issued pursuant to an indenture dated as of September 14, 2010 (the "**Base Indenture**") between the Bank and The Bank of New York Mellon, as trustee (the "**Trustee**"), as supplemented by the first supplemental indenture thereto dated as of April 2, 2019 (the "**First Supplemental Indenture**") and the second supplemental indenture thereto dated as of September 11, 2024 (the "**Second Supplemental Indenture**", and, collectively with the Base Indenture and the First Supplemental Indenture, and as amended or supplemented from time to time, the "**Indenture**").

We have participated, together with Willkie Farr & Gallagher LLP, United States counsel to the Bank, in the preparation of, or have reviewed, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. registration statement on Form F-3 (File No. 333-282307)
(the "**Registration Statement** "), including the prospectus constituting a part thereof, dated October 2, 2024 (the "**Base Prospectus** "), the preliminary prospectus supplement dated September 2, 2025 (the "**Preliminary Prospectus Supplement** "),
the final prospectus supplement dated September 2, 2025 (the "**Final Prospectus Supplement**" and, together with the
Preliminary Prospectus Supplement, the "**Prospectus Supplement**" and, together with the Base Prospectus, the "**Prospectus** "),
filed with the U.S. Securities and Exchange Commission under the Securities Act of 1933, as amended (the "**Act** ");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Underwriting Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the forms of certificates representing the Notes.

We have examined such statutes, public and corporate records, opinions, certificates and other documents, and considered such questions of law, as we have considered relevant and necessary as a basis for the opinions hereinafter set forth. In such examination we have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals, and the conformity to original documents of all documents submitted to us as certified or photostatic copies, portable document format or facsimiles.

For the purposes of the opinions expressed herein, we have, without independent investigation or verification, assumed that the Indenture has been duly authorized, executed and delivered by, and constitutes, a legal, valid and binding obligation of, each party thereto other than the Bank.

Additionally, for the purposes of the opinions expressed herein, we have relied upon a certificate of the Vice President, Corporate Secretary of the Bank dated September 8, 2025 (the "**Secretary's Certificate**"), as to certain matters of fact contained therein and the resolutions of the Board of Directors of the Bank relating to the Registration Statement, the Prospectus and the creation and issuance of the Notes and other related matters, and we have not independently verified the accuracy of the factual matters set forth therein upon which we have relied.

In expressing the opinion set forth in paragraph 1 below, as to the amalgamation of the Bank, we have relied exclusively upon a certificate of confirmation dated September 5, 2025 issued by the Office of the Superintendent of Financial Institutions and the Secretary's Certificate.

In expressing the opinion set forth in paragraph 2 below, we have assumed that the Notes will be issued in accordance with the provisions of the May 26, 2010, April 4, 2019, August 28, 2024 and March 5, 2025 resolutions, as applicable, of the Board of Directors of the Bank, which are attached as an exhibit to the Secretary's Certificate, and that such resolutions will not have been modified, repealed or superseded prior to the date of the issuance of the Notes in any way that would affect the substance of such opinion.

The Canada Deposit Insurance Corporation has the power to convert, or cause the Bank to convert, in whole or in part, by means of a transaction or series of transactions and in one or more steps, the prescribed liabilities of the Bank into the common shares of the Bank or any of its affiliates ("**Bail-In Conversion**"), if the Governor in Council (Canada) makes an order under paragraph 39.13(1)(d) of the *Canada Deposit Insurance Corporation Act* (Canada) (the "**CDIC Act**") in respect of the Bank. Regulations made under the CDIC Act and the *Bank Act* (Canada) (the "**Bank Act**") (collectively, the "**Bail-In Regulations**") prescribe the types of shares and liabilities that may be subject to a Bail-In Conversion. In general, any senior debt with an initial or amended term to maturity (including explicit or embedded options) greater than 400 days, that is unsecured or partially secured and has been assigned a CUSIP or ISIN or similar identification number is subject to a Bail-In Conversion. However, certain other debt obligations of the Bank, including structured notes, are not subject to a Bail-In Conversion. Subject to certain exceptions, a "structured note" is defined as a debt obligation that (a) specifies that the obligation's stated term to maturity, or a payment to be made by its issuer, is determined in whole or in part by reference to an index or reference point, including (i) the performance or value of an entity or asset, (ii) the market price of a security, commodity, investment fund or financial instrument, (iii) an interest rate, and (iv) the exchange rate between two currencies; or (b) contains any other type of embedded derivative or similar feature. To the extent the Debt Securities (as defined in the Prospectus) fall within this definition of a "structured note", they will accordingly not be subject to a Bail-in Conversion. Notwithstanding the above, any Debt Securities issued before the date the Bail-In Regulations came into force on September 23, 2018 are not subject to a Bail-In Conversion, unless the terms of such liability are, on or after September 23, 2018, amended to increase its principal amount or to extend its term to maturity and the liability, as amended, meets the requirements to be subject to a Bail-In Conversion.

The opinions contained herein are limited to matters governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein ("**Domestic Law**"). Such opinions are expressed with respect to the Domestic Law in effect on the date of this opinion and we do not accept any responsibility to take into account or inform the addressee, or any other person authorized to rely on this opinion, of any changes in law, facts or other developments subsequent to this date that do or may affect the opinions we express, nor do we have any obligation to advise you of any other change in any matter addressed in this opinion or to consider whether it would be appropriate for any other person other than the addressee to rely on our opinion.

Based and relying upon and subject to the qualifications set forth herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Bank is a bank amalgamated under and governed by the
Bank Act and has the corporate power to execute, deliver and perform its obligations under the Indenture and to create, issue and sell
the Notes as contemplated in the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. All necessary corporate action has been taken by the Bank to authorize the creation, issuance, sale and
delivery of the Notes; when the Notes have been duly executed and authenticated by the Trustee, issued in accordance with the Indenture
and delivered against payment therefor as contemplated in the Registration Statement, the Prospectus and the Underwriting Agreement, the
Notes will be, to the extent issuance, execution and delivery are matters governed by Domestic Law, duly issued, executed and delivered
by the Bank and, to the extent validity of the Notes is a matter governed by Domestic Law, the Notes will be valid obligations of the
Bank.

The opinion set forth in paragraph 2 above is subject to and may be limited by the following qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) general principles of equity, including the principle of granting equitable remedies such as specific
performance and injunctive relief, are subject to the discretion exercisable by a court of competent authority and/or jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) enforceability may be limited by bankruptcy, insolvency, winding-up, liquidation or other similar laws
of general application affecting the enforcement of creditors' rights generally (including the provisions of the Bank Act respecting
such matters);

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the enforcement of any rights against the Bank under the Indenture with respect to indemnity or contribution
may be limited by applicable law and may not be ordered by a court on the grounds of public policy and may, therefore, not be available
in any particular instance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) a court in the Province of Ontario may decline to enforce provisions in any document which purport to
allow a determination, calculation or certificate of a party thereto as to any matter provided for therein to be final, conclusive or
binding upon any other party thereto if such determination is found to be inaccurate on its face or to have been reached or made on any
arbitrary or fraudulent basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) enforceability of the Indenture or a provision of the Indenture may be subject to the provisions of the *Limitations Act*, 2002 (Ontario), and we express no opinion as to whether a court may find any provision of the Indenture to be
unenforceable on the basis that such provision is an attempt to vary or exclude a limitation period under such Act; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) pursuant to the *Currency Act* (Canada), a judgment by a court in any province in Canada may be awarded
in Canadian currency only and such judgment may be based on a rate of exchange which may be the rate in existence on a day other than
the day of payment of such judgment.

This opinion is rendered solely in connection with the transactions covered hereby, is limited to the matters stated herein, and no opinions may be implied or inferred beyond matters expressly stated herein.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us under the headings "*Legal Matters*", "*Material Income Tax Consequences—Canadian Taxation*", "*Limitations on Enforcement of U.S. Laws Against CIBC, Its Management and Others*" and "*Validity of Securities*" in the Prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required by the Act or the rules and regulations promulgated thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Bank is a bank amalgamated under and governed by the *Bank Act* (Canada) (the **Bank Act**)
and is listed on Schedule 1 to the Bank Act, is duly qualified to carry on its business in each jurisdiction in which the conduct of its
business or the ownership, leasing or operation of its property and assets requires such qualification except to the extent that the failure
to so qualify or be in good standing would not, individually or in the aggregate, reasonably be expected to have, a material adverse effect
on the condition, financial or otherwise, or the results of operations or business of the Bank and its subsidiaries, taken as a whole
(a **Material Adverse Effect**), and has all requisite power and authority (corporate and other) to conduct its businesses and to own,
lease and operate its properties and assets as described in the Time of Sale Prospectus, except where failure to do so would not reasonably

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Each "significant subsidiary" (as defined in Rule 1-02(w) of Regulation S-X under the Securities
Act) (the **Significant Subsidiaries**) of the Bank has been duly incorporated and is validly existing and in good standing under the
laws of the relevant jurisdiction set forth opposite its name in Column 2 in Schedule 3 to this Agreement, and each Significant Subsidiary
is duly qualified to carry on its business in each jurisdiction in which the conduct of its business or the ownership, leasing or operation

individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, and has all requisite power and authority
(corporate and other) to conduct its business and to own, lease and operate its properties and assets as described in the Time of Sale
Prospectus, except where failure to do so would not reasonably be expected to have a Material Adverse Effect.

in all respects with all applicable laws, rules and regulations of each jurisdiction in which its business is carried on and holds all
licenses, permits, approvals, consents, certificates, registrations and authorizations (whether governmental, regulatory or otherwise)
from the relevant regulatory or governmental authority in all such jurisdictions in which the Bank or its Significant Subsidiaries conduct
business, to enable its business to be carried on as now conducted and its property and assets to be owned, leased and operated, except
in each case where the failure to be in such compliance or to hold such license, permit, approval, consent, certificate, registration
or authorization would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and all such licenses,
permits, approvals, consents, certificates, registrations and authorizations are in good standing and in effect, except where the failure
to be in good standing or in effect would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect,
and none of the same contains any term, provision, condition or limitation which will have a Material Adverse Effect.

of incorporation, by-laws, partnership agreement or other constitutive documents or (ii) is in default, and no event has occurred that,
with notice or lapse of time or both, would constitute such a default, in the due performance or observance of any loan agreement, indenture,
mortgage, deed of trust or other agreement or instrument to which it is a party or by which it is bound, except in the case of clause
(ii), to the extent any such default would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The execution and delivery by the Bank of this Agreement, and the performance by the Bank of its obligations
under this Agreement, the Indenture and the Securities, will not result in a breach of or default under, and will not create a state of
facts which, after notice or lapse of time or both, will result in a breach or default under, and will not conflict with:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any of the terms, conditions or provisions of the Bank Act or the by-laws of the Bank or the terms, conditions

Subsidiaries;

regulatory or otherwise) issued to the Bank or any Significant Subsidiary or any agreement, indenture, mortgage, deed of trust, lease,
document or instrument to which the Bank or any Significant Subsidiary is a party or by which it is contractually bound at the Time of
Delivery (as defined herein), except for breaches or violations which would not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) any statute, regulation or rule applicable to the Bank or any Significant Subsidiary, or any judgment,
order or decree of any governmental body, agency or court having jurisdiction over the Bank or any Significant Subsidiary, except for
breaches or violations which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The Bank has not filed any confidential material change report with any of the applicable Canadian securities
commissions or similar regulatory authorities, the Toronto Stock Exchange or any other self-regulatory authority which remains confidential.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) All of the issued shares of capital stock of each Significant Subsidiary are validly authorized, issued
and outstanding, are fully paid and non-assessable and are owned directly or indirectly by the Bank, free and clear of all mortgages,
liens, charges, pledges, security interests, encumbrances, claims or demands whatsoever.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) This Agreement has been duly authorized, executed and delivered by the Bank.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) On or before the Time of Delivery, all actions required to be taken by or on behalf of the Bank, including
the passing of all requisite resolutions of its directors, will have occurred so as to validly authorize, issue and sell the Securities
as contemplated by this Agreement, and duly, punctually and faithfully perform all the obligations to be performed by it under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) No consent, approval, authorization or order of, or qualification with, any relevant regulatory or governmental
authority having jurisdiction over the Bank or any of its subsidiaries or any of their properties (**Governmental Authorization**)
is required in connection with the issuance and sale of the Securities or the consummation by the Bank of the transactions contemplated
by this Agreement or the Indenture, except such as have been, or will have been prior to the Time of Delivery, obtained under the laws
of the provinces and territories of Canada, the Securities Act and the Trust Indenture Act and such Governmental Authorizations as may
be required under state securities or blue sky laws in connection with the purchase and distribution of the Securities by the Underwriters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) The Indenture has been duly qualified under the Trust Indenture Act and the Indenture has been duly authorized,
executed and delivered by the Bank and constitutes a legal, valid and binding obligation of the Bank, enforceable in accordance with its
terms, except as enforcement thereof may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization or similar laws relating
to or affecting creditors' rights generally and general principles of equity and subject to the qualification that equitable remedies
may only be granted in the discretion of a court of competent jurisdiction (the **Enforceability Exceptions**).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) The Securities have been duly authorized by the Bank and, when executed by the Bank and authenticated
by the Trustee in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with
the terms of this Agreement, will constitute valid and binding obligations of the Bank, enforceable in accordance with their terms, subject
to the Enforceability Exceptions, and the Securities will be entitled to the benefits of the Indenture and the Securities conform, or
will conform, to the description thereof in the Time of Sale Prospectus and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(r) The consolidated financial statements of the Bank included or incorporated by reference in the Time of
Sale Prospectus, the Prospectus and the Registration Statement, together with the related schedules and notes, present fairly in all material
respects the consolidated financial position of the Bank and its subsidiaries at the dates indicated and the consolidated results of operations
and the consolidated changes in financial position of the Bank and its subsidiaries for the periods specified; and such consolidated financial
statements, together with the related schedules and notes, have been prepared in conformity with International Financial Reporting Standards
as issued by the International Accounting Standards Board (**IFRS**), including the accounting requirements of the Office of the Superintendent
of Financial Institutions (Canada), consistently applied throughout the periods involved, except as disclosed therein.

provincial, state, municipal or other governmental department, commission, board, agency or body, domestic or foreign, now pending, or,
to the knowledge of the Bank, threatened against or affecting the Bank or any of its subsidiaries (i) other than proceedings described
in all material respects in the Time of Sale Prospectus and proceedings that would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect or (ii) that is required to be described in the Registration Statement or the Prospectus and
is not so described.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(t) Except as disclosed in the Time of Sale Prospectus, there are no contracts, agreements or understandings
between the Bank and any person that would give rise to a valid claim against the Bank or any Underwriter for a brokerage commission,
finder's fee or other like payment in connection with the offering of the Securities contemplated hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(u) Except as set forth in the Time of Sale Prospectus, neither the Bank nor any of the Bank's subsidiaries
is a party to any contract with or other undertaking to, or is subject to any governmental order by, or is a recipient of any presently

to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) The Bank is not, and after giving effect to the offering and sale of the Securities and the application
of the proceeds thereof as described under "Use of Proceeds" in the Time of Sale Prospectus and the Prospectus, will not be,
required to register as an "investment company" as such term is defined in the Investment Company Act of 1940, as amended.

is the external auditor who prepared the Reports of Independent Registered Public Accounting Firm to the shareholders and directors of
the Bank in accordance with the standards of the Public Company Accounting Oversight Board (United States) (the **PCAOB**) –
which includes the reports on the Bank's consolidated financial statements and internal control over financial reporting. Ernst
& Young LLP is an independent registered public accounting firm as required by the Securities Act and the rules and regulations of
the Commission and the rules and regulations of the PCAOB.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) Neither the Bank nor any of its Significant Subsidiaries has taken, directly or indirectly, any action
designed to cause or result in, or which might cause or result in, the stabilization or manipulation of the price of the Securities to
facilitate the sale or resale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(y) The Bank maintains a system of internal control over financial reporting (as such term is defined in Rule
13a-15(f) under the Exchange Act) that has been designed by the Bank's principal executive officer and principal financial officer,
or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with IFRS. The management of the Bank concluded that such internal control over financial
reporting was effective as of October 31, 2024. Except as disclosed in the Time of Sale Prospectus, since October 31, 2024, there has
been no change in the Bank's internal control over financial reporting that has materially affected, or is reasonably likely to
materially affect, the Bank's internal control over financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(z) The Bank maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under
the Exchange Act) that have been designed to ensure that material information relating to the Bank and its subsidiaries is made known
to the Bank's principal executive officer and principal financial officer by others within those entities. Based on the evaluation
of these disclosure controls and procedures, the Bank's Chief Executive Officer and Chief Financial Officer concluded that the Bank's
disclosure controls and procedures were effective as of October 31, 2024.

Corruption of Foreign Public Officials Act (Canada), the United Kingdom Bribery Act 2010, the U.S. Foreign Corrupt Practices Act of 1977,
as amended, and the rules and regulations thereunder (the **FCPA)**, or any applicable similar law or regulation of any other jurisdiction
(collectively, the **Anti-Corruption Legislation**), including, without limitation, (i) making use of the mails or any means or instrumentality
of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or
other property, gift, promise to give, or authorization of the giving of anything of value to any "foreign official" (as such
term is defined in the FCPA), any foreign political party or official thereof or any candidate for foreign political office, or (ii) making,
authorizing, promising to make, authorizing the giving of, accepting, requesting or agreeing to receive a bribe or other unlawful payment
prohibited under the Anti-Corruption Legislation, in either case, if it would have a material adverse effect on the offer of the Securities
as contemplated by this Agreement; and the Bank and its subsidiaries and controlled affiliates maintain at all times adequate systems,
controls and procedures reasonably designed to comply with the Anti-Corruption Legislation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(bb) The operations of the Bank and its subsidiaries are and have been conducted in all material respects in
compliance with the applicable financial recordkeeping and reporting requirements and anti-money laundering statutes of all jurisdictions

or guidelines, issued, administered or enforced by any applicable governmental agency, including without limitation, the Proceeds of Crime
(Money Laundering) and Terrorist Financing Act (Canada) and the Currency and Foreign Transactions Reporting Act of 1970 (the **Bank Secrecy Act**), as amended by the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism
Act of 2001 (the **USA PATRIOT Act**) (collectively, the **Anti-Money Laundering Laws**), and no action, suit or proceeding by or
before any court or governmental agency, authority or body or any arbitrator involving the Bank or any of its subsidiaries with respect
to the Anti-Money Laundering Laws is pending or, to the best knowledge of the Bank, threatened which would have a material adverse effect
on the offer of the Securities as contemplated by this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(cc) None of the Bank or any of its subsidiaries nor, to the knowledge of the Bank, any director, officer,
agent, employee or controlled affiliate of the Bank or any of its subsidiaries (i) is the subject of any sanctions administered, enacted
or enforced by the Office of Foreign Assets Control of the U.S. Department of the Treasury (**OFAC**) or any other U.S., Canadian,
European Union, United Nations or United Kingdom economic sanctions or any equivalent sanctions authority with jurisdiction over the Bank

2. Agreements to Sell and Purchase

The Bank hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Bank the respective principal amounts of Securities set forth in Schedule 2 hereto opposite its name at the applicable purchase price set forth in Schedule 4 hereto.

3. Public Offering

The Bank is advised by the Representatives that the Underwriters propose to make a public offering of their respective portions of the Securities as soon after this Agreement has been entered into as in the Representatives' judgment is advisable. The Bank is further advised by the Representatives that the Securities are to be offered to the public upon the terms set forth in the Time of Sale Prospectus and the Prospectus.

4. Payment and Delivery

Payment for the Securities shall be made to or upon the order of the Bank by wire transfer payable in funds immediately available to an account specified by the Bank on the Closing Date and time set forth in Schedule 1 hereto, or at such other time on the same or such other date, not later than the fifth business day thereafter, as may be reasonably designated by the Representatives in writing. The time and date of such payment are herein referred to as the **Time of Delivery** and such date, the **Closing Date**.

At the Time of Delivery, the Bank shall pay the Underwriters fees (the Underwriters' Fees) equal to 0.150% of the aggregate principal amount of the Floating Rate Notes, 0.150% of the aggregate principal amount of the 2028 Fixed-to-Floating Rate Notes and 0.350% of the aggregate principal amount of the 2031 Fixed-to-Floating Rate Notes. The parties agree that the Underwriters shall set off the Underwriters' Fees against a portion of the purchase price payable to the Bank in an amount equal to the Underwriters' Fees and payment by the Underwriters to the Bank in accordance with the above paragraph of the purchase price net of the Underwriters' Fees shall be full satisfaction of the Underwriters' obligation to pay the purchase price for the Securities and of the Bank's obligation to pay the Underwriters' Fees. For the avoidance of doubt, the purchase price applicable to the respective principal amounts of Securities set forth in Schedule 4 hereto is, in each case, presented on a gross basis, without netting of the applicable Underwriters' Fee payable pursuant to this Section 4. Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof. Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct and agree to with the Bank.

5. Conditions to the Underwriters' Obligations

The several obligations of the Underwriters are subject, in the discretion of the Representatives, to the condition that all representations and warranties and other statements of the Bank in this Agreement as at the date hereof and at, and as of, the Time of Delivery, are true and correct, the condition that the Bank shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

rating organization," as such term is used in section 3(a)(62) under the Exchange Act; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) there shall not have occurred any change, or any development involving a prospective change, in the condition,
financial or otherwise, or in the earnings, business or operations of the Bank and its subsidiaries, taken as a whole, from that set forth

of the Representatives, impracticable to market the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Underwriters shall have received on the Closing Date a certificate, dated the Closing Date and signed

The Bank will furnish to the Representatives conformed copies of such opinions, certificates, letters and other documents in such number as the Representatives will reasonably request.

6. Covenants of the Bank

The Bank covenants with each Underwriter as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) To prepare the Prospectus in a form reasonably approved by the Representatives and to file the Prospectus
with the Commission pursuant to Rule 424(b) under the Securities Act not later than the Commission's close of business on the second
business day following the execution and delivery of this Agreement; before amending or supplementing the Registration Statement, the
Time of Sale Prospectus or the Prospectus prior to the Time of Delivery, to furnish to the Representatives a copy of each such proposed
amendment or supplement and not to file any such proposed amendment or supplement to which the Representatives shall have reasonably objected
in a timely manner by written notice to the Bank; to file promptly all reports required to be filed by the Bank with the Commission pursuant
to Section 13(a), 13(c) or 15(d) of the Exchange Act for so long as the delivery of a prospectus is required in connection with the offering
or sale of the Securities, and during such same period to advise the Representatives, promptly after it receives notice thereof, (A) of
the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Preliminary Prospectus
or the Prospectus has been filed, in each case, as applicable, with the Commission, (B) of the issuance by the Commission of any stop
order or of any order preventing or suspending the use of any prospectus relating to the Securities or the effectiveness of the Registration
Statement, (C) of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or the initiation or
threatening of any proceeding for any such purpose, or (D) of any request by the Commission for the amending or supplementing of the Registration
Statement, the Base Prospectus, the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus or for additional information
relating to the Securities; and, in the event of the issuance of any such stop order or of any such order preventing or suspending the
use of any prospectus relating to the Securities or suspending any such qualification, to promptly use its best efforts to obtain the
withdrawal of such order.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) To endeavor to qualify the Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions as the Representatives shall reasonably request; *provided* that in no event shall the Bank be obligated to qualify
to do business in any jurisdiction where it is not now so qualified, to file any general consent to service of process or to take any
action that would subject it to general service of process or to taxation in any jurisdiction where it is not now so subject.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) To furnish to the Representatives, without charge, and to each of the Underwriters, so long as delivery
of a prospectus by an Underwriter or dealer may be required by the Securities Act, as many copies of the Time of Sale Prospectus, the
Prospectus, any documents incorporated therein by reference and any supplements and amendments thereto as the Representatives may reasonably
request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) To furnish to the Representatives a copy of each proposed free writing prospectus to be used by, or referred
to by, the Bank and not to use or refer to any proposed free writing prospectus to which the Representatives reasonably objects. Each
free writing prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the rules and
regulations of the Commission on the date of first use, and the Bank will comply with any filing requirements applicable to such free
writing prospectus pursuant to Rule 433 of the rules and regulations of the Commission and each free writing prospectus will not, as of
its issue date and through the time the Securities are delivered, include any information that conflicts with the information contained
in the Registration Statement, the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Other than the filing with the Commission of the final term sheet substantially in the form set forth
in Schedule 4 hereto, not to knowingly take any action that would result in an Underwriter or the Bank being required to file with the
Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that
the Underwriter otherwise would not have been required to file thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) If the Time of Sale Prospectus is being used to solicit offers to buy the Securities at a time when the
Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary
to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts
with the information contained in the Registration Statement then on file, or if it is necessary to amend or supplement the Time of Sale
Prospectus or to file under the Exchange Act any document incorporated by reference in the Time of Sale Prospectus in order to comply
with the Securities Act, the Exchange Act or the Trust Indenture Act, forthwith to notify the Representatives and, upon the request of
the Representatives, prepare, file with the Commission, as applicable, and furnish, at its own expense, to the Underwriters and to any
dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus
as so amended or supplemented will not, in the light of the circumstances when delivered to a prospective purchaser, be misleading or
so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the
Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) If, during such period after the filing of the Prospectus with the Commission, the Prospectus (or in lieu
thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by
an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus
in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred
to in Rule 173(a) under the Securities Act) is delivered to a purchaser, not misleading, or if it is necessary to amend or supplement
the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the
Securities Act, the Exchange Act or the Trust Indenture Act, forthwith to notify the Representatives, and, upon the request of the Representatives,
prepare, file with the Commission, as applicable, and furnish, at its own expense, to the Underwriters and to the dealers (whose names
and addresses the Representatives will furnish to the Bank) to which Securities may have been sold by the Representatives on behalf of
the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the
Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice
referred to in Rule 173(a) under the Securities Act) are delivered to a purchaser, be misleading or so that the Prospectus, as amended
or supplemented, will comply with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) To make generally available to the Bank's security holders and to the Representatives as soon as
practicable, but in any event not later than eighteen months after the effective date (as defined in Rule 158(c) under the Securities
Act) of the Registration Statement, an earnings statement of the Bank and its subsidiaries (which need not be audited) covering a period
of at least twelve months beginning with the first fiscal quarter of the Bank occurring after the date of this Agreement which shall satisfy
the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder; *provided* that
the Bank may make such earnings statements generally available by filing quarterly and annual reports with the Commission as may be required
by the Exchange Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated,
to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees,
disbursements and expenses of the Bank's counsel and the Bank's accountants in connection with the preparation and filing
of the Base Prospectus, the Preliminary Prospectus, the Prospectus and any amendment or supplement thereof with the Commission, the registration
and delivery of the Securities under the Securities Act and all other fees or expenses in connection with the preparation and filing of
the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, any free writing
prospectus prepared by or on behalf of, used by, or referred to by the Bank and amendments and supplements to any of the foregoing, including
the filing fees payable to the Commission relating to the Securities, all printing costs associated therewith, and the mailing and delivering
of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the
transfer and delivery of the Securities to the Underwriters, including any transfer or similar taxes payable thereon, (iii) the cost of
printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Securities under state
securities laws and all expenses in connection with the qualification of the Securities for offer and sale under state securities laws
as provided in Section 6(b) hereof, including filing fees and the reasonable and documented fees and disbursements of counsel for the
Underwriters in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) all filing
fees and the reasonable and documented fees and disbursements of counsel to the Underwriters incurred in connection with the review and
qualification of the offering of the Securities by the Financial Industry Regulatory Authority, Inc., (v) any fees charged by the rating
agencies for the rating of the Securities, (vi) the cost of the preparation, issuance and delivery of the Securities, (vii) the fees and
expenses of any Trustee and any agent of any Trustee and the reasonable fees and disbursements of counsel for any Trustee in connection
with any Indenture and the Securities, (viii) the costs and expenses of the Bank relating to investor presentations on any "road
show" undertaken in connection with the marketing of the offering of the Securities, including, without limitation, expenses associated
with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics,
fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Bank, and travel
and lodging expenses of the representatives and officers of the Bank and any such consultants (ix) the document production charges and
expenses associated with printing this Agreement, (x) the services of Ernst & Young LLP, (xi) the services of Willkie Farr & Gallagher
LLP and Blake, Cassels & Graydon LLP and (xii) all other costs and expenses incident to the performance of the obligations of the
Bank hereunder for which provision is not otherwise made in this Section 6. It is understood, however, that, except as provided in this
Section 6, Section 8 entitled "Indemnity and Contribution," and the last paragraph of Section 9 below, the Underwriters will
pay all of their own costs and expenses including, transfer taxes payable on resale of any of the Securities by them, any advertising
expenses connected with any offers they may make and the fees and disbursements of their counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) During the period beginning on the date hereof and continuing to and including the Closing Date, not to
offer, sell, contract to sell or otherwise dispose of in the United States any debt securities of the Bank or warrants to purchase or
otherwise acquire debt securities of the Bank substantially similar to the Securities (other than (i) the Securities, (ii) commercial
paper or Yankee certificates of deposit with a maturity of no more than 12 months issued in the ordinary course of business or (iii) securities
or warrants permitted with the prior written consent of the Representatives).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) To prepare a final term sheet relating to the offering of the Securities, containing only information
that describes the final terms of the Securities or the offering in a form consented to by the Representatives (such consent not to be
unreasonably withheld), and to file such final term sheet within two days of the later of the date such final terms have been established
for the offering of the Securities and the date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) The Bank will not take, directly or indirectly, any action designed to cause or result in, or that might
cause or result in, stabilization or manipulation of the price of the Securities to facilitate the sale or resale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) The Bank and each Underwriter, on a several basis, covenants and agrees that, during the distribution
of the Securities, it will not provide any potential investor with any materials or information in relation to the offer and sale of the
Securities or the Bank other than the Preliminary Prospectus, the Prospectus, the free writing prospectus, and any amendments or supplements
to the foregoing in accordance with this Agreement.

7. COVENANTS of the Underwriters

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each Underwriter represents and warrants to, and agrees with, the Bank and each other Underwriter that
it has not made, and will not make, any offer relating to the Securities that would constitute a free writing prospectus without the prior
consent of the Bank and the Representatives (such consent not to be unreasonably withheld), *provided, however*, that prior to the
preparation of the final term sheet substantially in the form set forth in Schedule 4 hereto, the Underwriters are authorized to use a
free writing prospectus that contains only information (i) describing the preliminary terms of the Securities or their offering or (ii)
describing the final terms of the Securities which will not be inconsistent with the final term sheet substantially in the form set forth
in Schedule 4 hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter represents and agrees that it has not offered or sold, directly or indirectly, and that
it will not, directly or indirectly, offer, sell or deliver, any of the Securities in or from Canada or to any resident of Canada, provided
that the Underwriters may, in their discretion, resell such Securities to the Canadian investment dealer affiliate of CIBC World Markets
Corp. Each Underwriter further agrees that it will include a comparable provision in any sub-underwriting, banking group or selling group
agreement or similar arrangement with respect to the Securities that may be entered into by such Underwriter.

CIBC World Markets Corp. further agrees that (i) any offer or sale by its Canadian investment dealer affiliate of the Notes, as contemplated in the paragraph above, purchased by it hereunder in Canada or to any resident of Canada shall only be effected on a private placement basis in accordance with applicable exemptions under the applicable securities laws in the relevant jurisdictions; and (ii) neither it nor its Canadian investment dealer affiliate will distribute or deliver the Prospectus or Prospectus Supplement or any other offering material relating to Securities purchased by it hereunder, in Canada in contravention of the securities laws or regulations of any province or territory of Canada.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Each Underwriter represents and warrants to, and agrees with, the Bank that none of the payments to be
made to the Underwriter by the Bank under this Agreement shall be for services rendered in Canada by or on behalf of such Underwriter.

8. Indemnity and Contribution

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Bank agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any
Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, each affiliate of any Underwriter
within the meaning of Rule 405 under the Securities Act and any agent of any Underwriter from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by or based upon any untrue statement or alleged untrue statement of a material fact contained
in the Registration Statement or any amendment thereof, the Base Prospectus, the Preliminary Prospectus, the Time of Sale Prospectus,
any issuer free writing prospectus or road show, each as defined in Rule 433(h) under the Securities Act, and, in the case of a road show,
as identified on Schedule 5 hereto, any Bank information that the Bank has filed, or is required to file, pursuant to Rule 433(d) under
the Securities Act or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished to the Bank in writing by such Underwriter through the Representatives expressly for
use therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Bank, its directors,
its officers who sign the Registration Statement and each person, if any, who controls the Bank within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Bank to such Underwriter,
but only with reference to information relating to such Underwriter furnished to the Bank in writing by such Underwriter through the Representatives
expressly for use in the Registration Statement or any amendment thereof, the Base Prospectus, any preliminary prospectus, the Time of
Sale Prospectus, the Prospectus or any amendment or supplement thereto, any issuer free writing prospectus or road show, each as defined
in Rule 433(h) under the Securities Act, and, in the case of a road show, as identified on Schedule 5 hereto, or any amendment or supplement
thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person
in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the **indemnified party**) shall promptly
notify the person against whom such indemnity may be sought (the **indemnifying party**) in writing and the indemnifying party, upon
request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party
and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related
to such proceeding; *provided, however*, that the failure to so notify the indemnifying party will not relieve it from any liability
which it may have under this Section 8 except to the extent it has been prejudiced in any material respect by such failure or from any
liability which it may have to an indemnified party otherwise under this Section 8. In any such proceeding, any indemnified party shall
have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named
parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, including that
the Underwriters have been advised by counsel that there may be one or more legal defenses available to the Underwriters which are different
from or additional to those available to the Bank and in the judgment of such counsel it is advisable for the Underwriters to employ separate
counsel or (iii) the Bank has failed to assume the defense of such action and employ counsel satisfactory to the Underwriters, in which
event the fees and expenses of such separate counsel will be paid by the Bank. It is understood that the indemnifying party shall not,
except as noted in the preceding sentence, in respect of the legal expenses of any indemnified party in connection with any proceeding
or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any
local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm
shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 8(a), and by the Bank, in
the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent (which consent will not be unreasonably withheld), but if settled with such consent or if there be
a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability
by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences
of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written
consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and
(ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending
or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought
hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding and does not include any statements as to or any findings of fault, culpability
or failure to act by or on behalf of any indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) To the extent the indemnification provided for in Section 8(a) or Section 8(b) is unavailable to an indemnified
party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under
such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits
received by the Bank on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation
provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause 8(d)(i) above but also the relative fault of the Bank on the one hand and of the Underwriters on the other
hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Bank on the one hand and the Underwriters on the other hand in
connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering
of the Securities (before deducting expenses) received by the Bank and the total underwriting discounts and commissions received by the
Underwriters bear to the aggregate initial public offering price of the Securities as set forth in the Prospectus. The relative fault
of the Bank on the one hand and the Underwriters on the other hand 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 the Bank or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 8
are several in proportion to the respective principal amounts of Securities they have purchased hereunder, and not joint.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Bank and the Underwriters agree that it would not be just or equitable if contribution pursuant to
Section 8(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 that does not take account of the equitable considerations referred to in Section 8(d). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed
to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection
with investigating or defending any such action or claim which is subject to Section 8(d). Notwithstanding the provisions of Section 8(d),
no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten
by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to any indemnified party at law or in equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties
and other statements of the Bank contained in this Agreement shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter
or any affiliate of any Underwriter or by or on behalf of the Bank, its officers or directors or any person controlling the Bank and (iii)
acceptance of and payment for any of the Securities.

9. Termination

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Underwriters may terminate this Agreement by notice given by the Representatives to the Bank, if after
the execution and delivery of this Agreement and prior to the Time of Delivery (i) trading generally shall have been suspended or materially
limited on, or by, as the case may be, any of the New York Stock Exchange or the Toronto Stock Exchange, (ii) trading of any securities
of the Bank shall have been suspended or materially limited on any exchange or in any over-the-counter market, (iii) a material disruption
in securities settlement, payment or clearance services in the United States or Canada shall have occurred, (iv) any moratorium on commercial
banking activities shall have been declared by U.S. federal, New York State, Canadian federal or Ontario provincial authorities, (v) there
shall have occurred any outbreak or escalation of hostilities involving the United States or Canada or there shall have been a declaration
of a national emergency or war by the United States or Canada, or (vi) any material adverse change in financial markets in the United
States or Canada should be such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the
offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.
Any termination of this Agreement pursuant to this Section 9 will be without liability on the part of the Bank or any Underwriter, except
as otherwise provided in Sections 6(j), 8 and 9(b) hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If the sale of the Securities provided for herein is not consummated by reason of acts of the Bank or
changes in circumstances of the Bank pursuant to this Section 9 which prevent this Agreement from becoming effective, or by reason of
any failure, refusal or inability on the part of the Bank to perform any agreement on its part to be performed or because any other condition
of the Underwriters' obligations hereunder is not fulfilled or if the Underwriters decline to purchase the Securities for any reason
permitted under this Agreement, the Bank will reimburse the Underwriters for all reasonable out-of-pocket disbursements (including fees
and expenses of counsel to the Underwriters) incurred by the Underwriters in connection with any investigation or preparation made by
them in respect of the marketing of the Securities or in contemplation of the performance by them of their obligations hereunder.

10. Effectiveness; Defaulting Underwriters

This Agreement shall become effective *upon* the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule 2 bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; *provided* that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-tenth of such principal amount of Securities set forth opposite its name in Schedule 2 hereto without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Bank for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Bank. In any such case either the Representatives or the Bank shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, the Time of Sale Prospectus or the Prospectus, as amended or supplemented, if applicable, or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11. Entire Agreement

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) This Agreement, together with any contemporaneous written agreements and any prior written agreements
(to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between
the Bank and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus,
the conduct of the offering, and the purchase and sale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Bank acknowledges that in connection with the offering of the Securities, notwithstanding any preexisting
relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by
the Underwriters:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) no fiduciary or agency relationship between the Bank and any other person, on the one hand, and the Underwriters,
on the other hand, exists (except to the extent disclosed in the Registration Statement, the Preliminary Prospectus, the Time of Sale
Prospectus and Prospectus);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Underwriters are not acting as advisors, experts or otherwise, to the Bank, including, without limitation,
with respect to the determination of the public offering price of the Securities, and such relationship between the Bank, on the one hand,
and the Underwriters, on the other hand, is entirely and solely a commercial relationship, based on arms-length negotiations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the Underwriters owe the Bank only those duties and obligations set forth in this Agreement and prior
written agreements (to the extent not superseded by this Agreement), if any; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Underwriters may have interests that differ from those of the Bank. The Bank waives to the full extent
permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection
with the offering of the Securities.

12. USA PATRIOT Act

In accordance with the requirements of the USA PATRIOT Act, the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Bank, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

13. Information Furnished by Underwriters

The Underwriters severally confirm that the information appearing in the list of names of each of the Underwriters under the caption "Underwriting (Conflicts of Interest)" in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus and the statements in the tenth and eleventh paragraphs under the caption "Underwriting (Conflicts of Interest)" in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus, constitute the only written information furnished to the Bank by the Representatives on behalf of the Underwriters.

Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement, the Prospectus,
the Registration Statement, or the transactions contemplated hereby or thereby. The Bank irrevocably waives, to the fullest extent permitted
by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such
a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum. To the
extent that the Bank has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any
court or from any legal process with respect to itself or its property, the Bank irrevocably waives, to the fullest extent permitted by
law, such immunity in respect of any such suit, action or proceeding.

23. Judgment Currency

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Representatives could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Bank with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency.

The Bank has filed a shelf registration statement on Form F-3 (File No. 333-282307) (including a base prospectus) and a preliminary prospectus supplement dated September 2, 2025 (including the base prospectus, the "**Prospectus**") with the U.S. Securities and Exchange Commission (the "**SEC**") for the offering to which this communication relates. Before you invest, you should read the Prospectus and the documents incorporated therein by reference that the Bank has filed with the SEC for more complete information about the Bank and this offering. You may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, the Bank or any underwriter participating in the offering will arrange to send you the Prospectus and any document incorporated therein by reference if you request such documents by calling CIBC World Markets Corp. toll-free at (800) 282-0822; BNP Paribas Securities Corp. toll-free at (800) 854-5674; BofA Securities, Inc. toll-free at (800) 294-1322; Citigroup Global Markets Inc. toll-free at (800) 831-9146; Goldman Sachs & Co. LLC toll-free at (866) 471-2526; or UBS Securities LLC toll-free at (833) 481-0269.

\*\*We expect that delivery of the Notes will be made against payment therefor on or about September 8, 2025, which is four business days following the date of pricing of the Notes (this settlement cycle being referred to as "T+4"). Under Rule 15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their Notes on any date prior to the business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade their Notes on any date prior to one business day before delivery should consult their own advisor.
