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, 2025. Except as disclosed in the Time of Sale Prospectus, since October 31, 2025, there has

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, 2025.

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,

steps to confirm that each purchaser of Notes in the Qualifying Provinces is not an individual and meets the terms and conditions of the
"accredited investor exemption" as defined in NI 45-106, will obtain, as necessary, and retain relevant information and documentation
to evidence the steps taken to verify compliance with the exemption and provide to the Bank forthwith upon request all such information
or documentation as the Bank may reasonably request for the purpose of complying with a request from a securities regulator in the Qualifying
Provinces (including identifying whether the purchaser is purchasing for its own account and what category of "accredited investor"
the purchaser falls under).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) 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 the Canadian Offering Memorandum,
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, or the Canadian Offering Memorandum, 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 Notes 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 Notes 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 Notes 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 Notes.

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(i), 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 Notes 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 the Notes that it has or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes 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 Notes to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Notes set forth opposite their respective names in Schedule 2 bears to the aggregate principal amount of Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Notes 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 Notes 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 Notes 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 Notes and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives and the Bank for the purchase of such Notes 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 Notes, 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 ninth and tenth 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.

14. Research Analyst Independence

The Bank acknowledges that the Underwriters' research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters' research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Bank and/or the offering of the Securities that differ from the views of their respective investment banking divisions. The Bank hereby waives and releases, to the fullest extent permitted by law, any claims that the Bank may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Bank by such Underwriters' investment banking divisions. The Bank acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

15. Counterparts

This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This agreement may be executed by manual, facsimile or electronic signature, and signatures of the parties hereto transmitted by electronic delivery methods shall be deemed to be their original signatures for all purposes and shall constitute effective execution and delivery of this Agreement. The use of electronic signatures, records and delivery methods shall be of the same legal effect, validity or enforceability as a manually executed signature and physical delivery thereof to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law.

16. Applicable Law

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

17. Headings

The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

18. Notices

All communications hereunder shall be in writing (including email) and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to the Representatives at the addresses set forth in Schedule 1 hereto; and if to the Bank shall be delivered, mailed or sent to the address set forth in Schedule 1 hereto.

19. RECOGNITION OF THE U.S. Special Resolution Regimes

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S.
Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement,
will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and
any such interest and obligation, were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter
becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against
such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special
Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) As used in this Section 19:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) "**BHC Act Affiliate**" has the meaning assigned to the term "affiliate" in,
and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) "**Covered Entity**" means any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) "covered entity" as that term is defined in, and interpreted in accordance with, 12 C.F.R.
§ 252.82(b);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) a "covered bank" as that term is defined in, and interpreted in accordance with, 12 C.F.R.
§ 47.3(b); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) a "covered FSI" as that term is defined in, and interpreted in accordance with, 12 C.F.R.
§ 382.2(b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) "**Default Right**" has the meaning assigned to that term in, and shall be interpreted
in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) "**U.S. Special Resolution Regime**" means each of (i) the Federal Deposit Insurance Act
and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the
regulations promulgated thereunder.

20. Submission to Jurisdiction; Appointment of Agent for Service

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Bank irrevocably submits to the non-exclusive jurisdiction of any New York State or United States
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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Bank hereby irrevocably appoints Achilles M. Perry of Canadian Imperial Bank of Commerce, with offices
at 300 Madison Avenue, New York, NY 10017 as its agent for service of process in any suit, action or proceeding described in the preceding
paragraph and agrees that service of process in any such suit, action or proceeding may be made upon it at the office of such agent. The
Bank waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto.
The Bank represents and warrants that such agent has agreed to act as the Bank's agent for service of process, and the Bank agrees
to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment
in full force and effect.

21. waiver of right to trial by jury

EACH OF THE PARTIES HEREBY EXPRESSLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER THIS AGREEMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF ANY OF THE PARTIES WITH RESPECT TO THIS AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH OF THE PARTIES AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY OF THE PARTIES MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 21 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

22. 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. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Bank agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Bank an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

|  | &nbsp;&nbsp; Upon any redemption by the Bank of the Preferred Shares (as defined below) held in the Limited Recourse Trust (as defined below) in accordance with their terms prior to the Maturity Date (such redemption will be subject to the prior written approval of the Superintendent), outstanding Notes with an aggregate principal amount equal to the aggregate face amount of Preferred Shares redeemed by the Bank shall automatically and immediately be redeemed, on a full and permanent basis, for a cash amount equal to the Redemption Price, without any action on the part of, or the consent of, the Noteholders. See the Final Term Sheet for the Preferred Shares attached hereto (the "Preferred Share Term Sheet") for circumstances under which the Preferred Shares may be redeemed or purchased for cancellation by the Bank. For certainty, to the extent that, in accordance with the terms of the Indenture (as defined in the Preliminary Prospectus Supplement), the Bank has immediately prior to or concurrently with such redemption of Preferred Shares redeemed or purchased for cancellation Notes with an aggregate principal amount equal to the aggregate face amount of Preferred Shares being redeemed, such requirement to redeem a corresponding aggregate principal amount of Notes shall be deemed satisfied.<br>The Bank will not redeem the Notes under any circumstances if such redemption would, directly or indirectly, result in the Bank's breach of any provision of the *Bank Act* (Canada) (the "Bank Act") or the Office of the Superintendent of Financial Institutions Canada's ("OSFI") Capital Adequacy Requirements (CAR) Guideline.<br>Any Notes redeemed by the Bank will be cancelled and will not be reissued.<br>As a result of the redemption provisions applicable to the Preferred Shares and the Notes, the Limited Recourse Trustee (as defined below) will, at all times prior to a Recourse Event (as defined below), hold one Preferred Share for each US$1,000 principal amount of Notes outstanding. |
|  | &nbsp;&nbsp;"Redemption Price" means 100% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date. |

---

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Limited Recourse:** | &nbsp;&nbsp;If (i) there is non-payment by the Bank of the principal amount of the Notes, together with any accrued and unpaid interest thereon, in cash, on the Maturity Date, (ii) a Failed Coupon Payment Date occurs, (iii) in connection with the redemption of the Notes, on the redemption date for such redemption, the Bank does not pay the applicable Redemption Price in cash, (iv) an event of default with respect to the Notes occurs or (v) a Trigger Event (as defined in the Preferred Share Term Sheet) occurs (each such event, a "Recourse Event"), while a Noteholder will have a claim against the Bank for the principal amount of the Notes and any accrued and unpaid interest thereon (which will then be due and payable), each such Noteholder's sole recourse in respect of such claim will be limited to such Noteholder's proportionate share of the assets held by a third party trustee (the "Limited Recourse Trustee") in respect of the Notes (the "Corresponding Trust Assets") in CIBC LRCN Limited Recourse Trust (the "Limited Recourse Trust"). The Limited Recourse Trustee will hold assets in the Limited Recourse Trust in respect of more than one series of limited recourse capital notes, and the assets (including the Bank's preferred shares) for each such series will be held separate from the assets for other series. Computershare Trust Company of Canada will act as the Limited Recourse Trustee. |
|  | &nbsp;&nbsp;Initially, at the time of issuance of the Notes, the Corresponding Trust Assets will consist of the Bank's Non-Cumulative 5-Year Fixed Rate Reset Class A Preferred Shares Series 64 (Non-Viability Contingent Capital (NVCC)) (the "Preferred Shares") issued prior to the issue date of the Notes at an issue price equal to the Canadian Dollar Equivalent (as defined in the Preferred Share Term Sheet) of US$1,000 per Preferred Share. Following the issuance of the Notes, the Corresponding Trust Assets may consist of (i) Preferred Shares (or proceeds with respect to the subscription for units of the Limited Recourse Trust by the Bank, which are to be used by the Limited Recourse Trustee to subscribe for Preferred Shares), (ii) cash, if the Preferred Shares are redeemed for cash, or purchased for cancellation, by the Bank with the prior written approval of the Superintendent (other than any portion of such cash in respect of any declared and unpaid dividends), (iii) common shares of the Bank ("Common Shares") issued upon the conversion of the Preferred Shares into Common Shares upon a Trigger Event and resulting NVCC Automatic Conversion (as defined in the Preferred Share Term Sheet) in connection with such Trigger Event (other than Dividend Common Shares (as defined below), if any) or (iv) any combination thereof, depending on the circumstances. |

---

---

| |
|:---|
| &nbsp;&nbsp; The number of Preferred Shares issued prior to the issue date of the Notes will be equal to the aggregate principal amount of the Notes to be issued on the issue date divided by US$1,000.<br>Upon the occurrence of a Recourse Event that is not a Trigger Event, the Limited Recourse Trustee will deliver to each Noteholder one Preferred Share for each US$1,000 principal amount of Notes held by such Noteholder, which shall be applied to the payment of the principal amount of the Notes, and such delivery of Preferred Shares will be the sole remedy of each Noteholder against the Bank for repayment of the principal amount of the Notes and any accrued but unpaid interest thereon then due and payable.<br>Upon the occurrence of a Recourse Event that is a Trigger Event, each Noteholder will be entitled to receive such Noteholder's proportionate share of the Corresponding Trust Assets and the Limited Recourse Trustee will deliver to each Noteholder such Noteholder's proportionate share of Common Shares issued upon the conversion of the Preferred Shares into Common Shares upon a Trigger Event and resulting NVCC Automatic Conversion in connection with such Trigger Event (other than Dividend Common Shares, if any). The number of Common Shares issuable in connection with the Trigger Event will be calculated based on a Share Value (as defined in the Preferred Share Term Sheet) of US$1,000, plus declared and unpaid dividends, if any, to, but excluding, the date of the Trigger Event, expressed in Canadian dollars. The delivery of such Common Shares shall be applied to the payment of the principal amount of the Notes, and such delivery of Common Shares will be the sole remedy of each Noteholder against the Bank for repayment of the principal amount of the Notes and any accrued but unpaid interest thereon then due and payable. See "NVCC Automatic Conversion" below. |
| &nbsp;&nbsp;Notwithstanding the foregoing, upon a Recourse Event that is a Trigger Event, holders of Notes will not be entitled to receive any Common Shares issued in respect of the portion of the Share Value equal to any declared and unpaid dividends (such Common Shares, the "Dividend Common Shares"), which Dividend Common Shares shall not be delivered to holders of Notes and either will be retained by the Limited Recourse Trustee or sold by the Limited Recourse Trust with the proceeds distributed to the Bank. As a result of the Dividend Waiver (as described in the Preferred Share Term Sheet), the Bank does not expect the NVCC Automatic Conversion Formula (as defined in the Preferred Share Term Sheet) to result in the issuance of any Dividend Common Shares in connection with a Recourse Event that is a Trigger Event. |
| &nbsp;&nbsp;The receipt by a Noteholder of its proportionate share of the Corresponding Trust Assets upon the occurrence of a Recourse Event shall exhaust all remedies of such Noteholder under the Notes. If a Noteholder does not receive its proportionate share of the Corresponding Trust Assets under such circumstances, the sole remedy of such Noteholder for any claims against the Bank shall be limited to a claim for the delivery of its proportionate share of such Corresponding Trust Assets. |
| &nbsp;&nbsp;In case of any shortfall resulting from the value of the Corresponding Trust Assets being less than the principal amount of and any accrued and unpaid interest on the Notes, all losses arising from such shortfall shall be borne by the Noteholders. |
| &nbsp;&nbsp;All claims of any Noteholder against the Bank under the Notes will be extinguished upon receipt by such Noteholder of its proportionate share of the Corresponding Trust Assets. |

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Purchase for Cancellation:** | &nbsp;&nbsp; The Bank may, at its option and at any time, with the prior written approval of the Superintendent, purchase the Notes, in whole or in part, in the open market, by tender (available to all holders of Notes), by private contract or otherwise, for cancellation, at any price or prices and upon such terms and conditions as the Bank in its absolute discretion may determine, subject, however, to any applicable law restricting the purchase of Notes.<br>If any Notes are so purchased for cancellation, subject to the provisions of the Bank Act, the prior written approval of the Superintendent and various restrictions on the retirement of Preferred Shares, the Bank shall redeem a corresponding number of Preferred Shares (which Preferred Shares will have an aggregate face amount equal to the aggregate principal amount of the Notes to be cancelled) then held in the Limited Recourse Trust.<br>Any Notes so purchased by the Bank will be cancelled and will not be reissued. |
| &nbsp;&nbsp;**NVCC Automatic Conversion:** | &nbsp;&nbsp;Upon the occurrence of a Trigger Event, each Preferred Share held in the Limited Recourse Trust will be automatically and immediately converted, on a full and permanent basis, without the consent of the holder thereof, the Limited Recourse Trustee, the Trustee (as defined in the Preliminary Prospectus Supplement) or the Canadian Co-Trustee (as defined in the Preliminary Prospectus Supplement), into the number of fully-paid and non-assessable Common Shares based on the Conversion Price (as defined in the Preferred Share Term Sheet) (an "NVCC Automatic Conversion"). See "NVCC Automatic Conversion" in the Preferred Share Term Sheet. |
|  | &nbsp;&nbsp;Immediately following such NVCC Automatic Conversion, pursuant to the limited recourse feature described above, each Noteholder will be entitled to receive such Noteholder's proportionate share of the Corresponding Trust Assets and the Limited Recourse Trustee will deliver to each Noteholder such holder's proportionate share of the Common Shares issued upon a Trigger Event and resulting NVCC Automatic Conversion in connection with such Trigger Event (other than Dividend Common Shares, if any). All claims of Noteholders against the Bank under the Notes will be extinguished upon receipt of such Common Shares. See "Limited Recourse" above. |
| &nbsp;&nbsp;**Subordination:** | &nbsp;&nbsp;The Notes will be direct unsecured obligations of the Bank constituting subordinated indebtedness within the meaning of the Bank Act and will rank subordinate to all of the Bank's deposit liabilities and all of the Bank's other indebtedness (including all of the Bank's other unsecured and subordinated indebtedness) from time to time issued and outstanding, except for such indebtedness which by its terms ranks equally in right of payment with, or is subordinate to, the Notes. |
|  | &nbsp;&nbsp;Upon the occurrence of a Recourse Event, including a Trigger Event or an event of default, the recourse of each Noteholder will be limited to the Noteholder's proportionate share of the Corresponding Trust Assets. The receipt by a Noteholder of its proportionate share of the Corresponding Trust Assets upon the occurrence of a Recourse Event shall exhaust all remedies of such Noteholder under the Notes. If a Noteholder does not receive its proportionate share of the Corresponding Trust Assets under such circumstances, the sole remedy of the Noteholder for any claims against the Bank will be limited to a claim for the delivery of such Corresponding Trust Assets. If the Corresponding Trust Assets that are delivered to the Noteholders under such circumstances consist of Preferred Shares or Common Shares, such Preferred Shares or Common Shares will rank on parity with the Bank's other Class A preferred shares ("Class A Preferred Shares") or Common Shares, as applicable. |

---

---

| | |
|:---|:---|
|  | &nbsp;&nbsp;The Notes will not constitute savings accounts, deposits or other obligations that are insured by the U.S. Federal Deposit Insurance Corporation, the Deposit Insurance Fund, the Canada Deposit Insurance Corporation or any other U.S. or Canadian governmental agency or under the *Canada Deposit Insurance Corporation Act* (Canada), the Bank Act or any other deposit insurance regime designed to ensure the payment of all or a portion of a deposit upon the insolvency of the deposit taking financial institution. |
| &nbsp;&nbsp;**Events of Default:** | &nbsp;&nbsp;The only events of default with respect to the Notes shall be the bankruptcy, insolvency, liquidation, or winding-up of the Bank. |
|  | &nbsp;&nbsp;An event of default will not include any non-payment by the Bank of the principal amount of or interest on the Notes, a default in the performance by the Bank of any other covenant of the Bank contained in the Indenture, or the occurrence of a Trigger Event (including an NVCC Automatic Conversion). |
|  | &nbsp;&nbsp;The occurrence of an event of default is a Recourse Event, for which the sole recourse of Noteholders will be limited to the delivery of the Corresponding Trust Assets. In case of an event of default, the delivery of the Corresponding Trust Assets to the Noteholders will exhaust all remedies of such Noteholders in connection with such event of default, and all claims of holders of Notes against the Bank under the Notes will be extinguished upon receipt of the Corresponding Trust Assets. See "Limited Recourse" above. |
| &nbsp;&nbsp;**Risk Factors:** | &nbsp;&nbsp;An investment in the Notes is subject to certain risks. Please refer to the Preliminary Prospectus Supplement for a discussion of those risks. As an investment in the Notes may become an investment in the Preferred Shares or Common Shares in certain circumstances (including upon the occurrence of a Trigger Event), and potential investors in the Notes should consider the risks discussed in the Preliminary Prospectus Supplement regarding the Preferred Shares and Common Shares in addition to the risks regarding the Notes. |
| &nbsp;&nbsp;**Prohibited Owners:** | &nbsp;&nbsp;The terms and conditions of the Notes will include mechanics to allow the Bank to attempt to facilitate a sale of Preferred Shares or Common Shares (issued upon a Recourse Event) on behalf of any Noteholders whom the Bank or its stock transfer agent has reason to believe is an Ineligible Person (as defined in the Preliminary Prospectus Supplement), Ineligible Government Holder (as defined in the Preliminary Prospectus Supplement), or any person who, by virtue of that delivery, would become a Significant Shareholder (as defined in the Preliminary Prospectus Supplement). |

---

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Use of Proceeds:** | &nbsp;&nbsp;The net proceeds from the sale of the Notes will be added to the Bank's funds and will be used for general corporate purposes, which may include the redemption of outstanding capital securities of the Bank, and/or repayment of other outstanding liabilities of the Bank. The Notes are expected to qualify as Additional Tier 1 capital of the Bank for regulatory purposes. |
| &nbsp;&nbsp;**No Public Trading Market:** | &nbsp;&nbsp; The Bank does not intend to apply for listing of the Notes on any securities exchange or to arrange for quotation on any automated quotation systems. There can be no assurance that an active trading market will develop for the Notes.<br>Upon a Trigger Event, pursuant to the limited recourse feature described above, Noteholders will become holders of Common Shares. The Bank currently intends to apply to list such Common Shares on the New York Stock Exchange and the Toronto Stock Exchange in accordance with their respective rules and requirements. |
| &nbsp;&nbsp;**Form and Denomination:** | &nbsp;&nbsp;The Notes will be registered in the name of the nominee of The Depository Trust Company. Minimum of US$200,000 and integral multiples of US$1,000 in excess thereof. |

The Bank has filed a shelf registration statement on Form F-3 (File No. 333-282307) and a preliminary prospectus supplement dated January 6, 2026 (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; 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 January 13, 2026, which is five business days following the date of pricing of the Notes (this settlement cycle being referred to as "T+5"). 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+5, 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.**

| **Restrictions on Dividends and Retirement of Shares:** | So long as any Preferred Shares are outstanding, the Bank will not, without the approval of the holders of the outstanding Preferred Shares, declare, pay or set apart for payment any dividends on any Class B preferred shares, any Common Shares or any other shares of the Bank ranking junior to the Preferred Shares (other than stock dividends payable in any shares of the Bank ranking junior to the Preferred Shares); redeem, purchase or otherwise retire any Class B preferred shares, any Common Shares or any other shares of the Bank ranking junior to the Preferred Shares (except out of the net cash proceeds of a substantially concurrent issue of shares ranking junior to the Preferred Shares); redeem, purchase or otherwise retire less than all of the Preferred Shares then outstanding; or, except pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provision attaching to any series of preferred shares of the Bank, redeem, purchase, or otherwise retire any other shares ranking on a parity with the Preferred Shares, unless, in each case, all cumulative dividends accrued and unpaid up to and including the applicable dividend payment date for the last completed period for which dividends were payable shall have been declared and paid or set apart for payment in respect of each series of cumulative Class A Preferred Shares then issued and outstanding and on all other cumulative shares ranking prior to or on a parity with the Class A Preferred Shares and there shall have been paid or set apart for payment all declared dividends in respect of each series of non-cumulative Class A Preferred Shares then issued and outstanding and on all other non-cumulative shares ranking prior to or on a parity with the Preferred Shares. |
| **Redemption:** | Except as noted below, the Preferred Shares will not be redeemable prior to the Initial Reset Date. <br>Subject to the provisions of the Bank Act, the prior consent of the Superintendent and to the provisions of the Preferred Shares, the Bank may, at its option, without the consent of the holder, redeem all or any part of the outstanding Preferred Shares, on the Initial Reset Date and on each January 28, April 28, July 28 and October 28 thereafter, by the payment of an amount in cash for each such share so redeemed of US$1,000 (or if then held in the Limited Recourse Trust, the Canadian Dollar Equivalent of US$1,000), together with any declared and unpaid dividends (of which none are expected for so long as the Preferred Shares are held by the Limited Recourse Trustee), to, but excluding, the date fixed for redemption. |

| | |
|:---|:---|
|  | When the Preferred Shares are held in the Limited Recourse Trust, subject to the provisions of the Bank Act, the prior consent of the Superintendent and to the provisions of the Preferred Shares, the Bank may also redeem all but not less than all of the outstanding Preferred Shares (i) at any time following a Regulatory Event Date (as defined in the Preliminary Prospectus Supplement), or (ii) at any time following the occurrence of a Tax Event Date (as defined in the Preliminary Prospectus Supplement), at the Bank's option without the consent of the holder, by the payment of an amount in cash for each such share so redeemed of the Canadian Dollar Equivalent of US$1,000 per Preferred Share, together with any declared and unpaid dividends (of which none are expected for so long as the Preferred Shares are held by the Limited Recourse Trustee) to, but excluding, the date fixed for redemption. |
|  | If at any time the Bank, with the prior written approval of the Superintendent, redeems Notes in accordance with their terms (including in connection with a redemption at the option of the Bank or a Regulatory Event Date or Tax Event Date) or purchases Notes, in whole or in part, in the open market, by tender, by private contract or otherwise, for cancellation, then the Bank shall, subject to the provisions of the Bank Act, the prior written approval of the Superintendent and the provisions of the Preferred Shares, redeem a corresponding number of Preferred Shares with an aggregate face amount equal to the aggregate principal amount of Notes redeemed or purchased for cancellation by the Bank, by the payment of an amount in cash for each such share so redeemed of the Canadian Dollar Equivalent of US$1,000 together with any declared and unpaid dividends (of which none are expected for so long as the Preferred Shares are held by the Limited Recourse Trustee) to, but excluding, the date fixed for redemption. |
|  | Concurrently with or upon the maturity of the Notes, subject to the provisions of the Bank Act, the prior written approval of the Superintendent and to the provisions of the Preferred Shares, the Bank shall redeem all but not less than all of the outstanding Preferred Shares by the payment of an amount in cash for each such share so redeemed of the Canadian Dollar Equivalent of US$1,000 per Preferred Share, together with any declared and unpaid dividends (of which none are expected for so long as the Preferred Shares are held by the Limited Recourse Trustee) to, but excluding, the date fixed for redemption, and unless otherwise satisfied, apply, or cause the Limited Recourse Trustee to apply, the proceeds of such redemption towards the repayment of the aggregate principal amount of and any accrued and unpaid interest on the Notes. |
|  | The Bank will give notice of any redemption to registered holders at least 10 and not more than 60 days prior to the redemption date. |
| **NVCC Automatic Conversion:** | Upon the occurrence of a Trigger Event (as defined below), each outstanding Preferred Share will automatically and immediately be converted, on a full and permanent basis, without the consent of the holder thereof, into the number of fully-paid and non-assessable Common Shares determined in accordance with the NVCC Automatic Conversion Formula set out below (an "NVCC Automatic Conversion"), rounding down, if necessary, to the nearest whole number of Common Shares. Fractions of Common Shares will not be issued or delivered pursuant to an NVCC Automatic Conversion and such number of Common Shares to be issued to such holder shall be rounded down to the nearest whole number of Common Shares and no cash payment will be made in lieu of a fractional Common Share. |

● the Superintendent publicly announces that the Bank has been advised, in writing, that the Superintendent is of the opinion that the Bank has ceased, or is about to cease, to be viable and that, after the conversion or write-off, as applicable, of all contingent instruments and taking into account any other factors or circumstances that are considered relevant or appropriate, it is reasonably likely that the viability of the Bank will be restored or maintained; or

● a federal or provincial government in Canada publicly announces that the Bank has accepted or agreed to accept a capital injection, or equivalent support, from the federal government or any provincial government or political subdivision or agent or agency thereof without which the Bank would have been determined by the Superintendent to be non-viable.

| | |
|:---|:---|
| **Common Share Corporate Event:** | In the event of a capital reorganization, consolidation, merger or amalgamation of the Bank or comparable transaction affecting the Common Shares, the Bank will take necessary action to ensure that holders of Preferred Shares receive, pursuant to an NVCC Automatic Conversion, the number of Common Shares or other securities that such holders would have received if the NVCC Automatic Conversion had occurred immediately prior to the record date for such event. |
| **Conversion into Another Series of Class A Preferred Shares:** | The Bank may at any time that the Preferred Shares are not held by the Limited Recourse Trustee, subject to the prior consent of the Superintendent, (i) give holders of the Preferred Shares the right, at their option, to convert such Preferred Shares into New Preferred Shares (as defined in the Preliminary Prospectus Supplement) of the Bank, or (ii) require the holders of Preferred Shares to convert such Preferred Shares into New Preferred Shares of the Bank. |
| **Purchase for Cancellation:** | Subject to the provisions of the Bank Act, the prior written approval of the Superintendent and to the provisions of the Preferred Shares, the Bank may at any time or from time to time purchase for cancellation the whole or any part of the outstanding Preferred Shares in the open market (including by private contracts), by tender or otherwise at the lowest price or prices at which in the opinion of the board of directors such shares are obtainable. |
| **Risk Factors:** | An investment in the Preferred Shares and Common Shares upon delivery of the assets of the Limited Recourse Trust, including upon the occurrence of a Trigger Event is subject to certain risks. Please refer to the Preliminary Prospectus Supplement for the offering for a discussion of those risks. |

If no calculation is provided as described above, then the Bank or its designee, after consulting such sources as it deems comparable to any of the foregoing calculations, or any such source as it deems reasonable from which to estimate the five-year treasury rate, will determine the U.S. Treasury Rate in its sole discretion.

If the Bank or its designee determines that there is such a replacement rate, then such replacement rate will replace the U.S. Treasury Rate (or then-current reset reference rate) for all purposes relating to the Notes in respect of such determination on such Interest Rate Calculation Date and all determinations on all subsequent Interest Rate Calculation Dates. If a replacement rate is utilized in accordance with the foregoing, the Bank or its designee in its sole discretion may adopt or make changes to any Interest Payment Date, Interest Rate Calculation Date, Interest Reset Date, other relevant date, Business Day convention, interest period or Rate Reset Period, the manner, timing and frequency of determining rates and amounts of interest that are payable on the Notes and the conventions relating to such determination, rounding conventions and any other relevant methodology for calculating such replacement rate, including any adjustment factor needed to make replacement rate comparable to the U.S. Treasury Rate, in a manner that is consistent with industry accepted practices for such replacement rate. If the Bank or its designee determines that there is no such replacement rate, then the interest rate for the applicable reset period will be: (a) if the first reset interest rate is to be determined, the initial interest rate or (b) if a subsequent reset interest rate is to be determined, the interest rate that was applicable for the preceding reset period.

The Notes shall be issued initially in the form of one or more fully registered global notes (each such global note, a "**Global Note**") deposited with DTC or its designated custodian or such other Depositary as any officer of the Bank may from time to time designate. Unless and until a Global Note is exchanged for Notes in certificated form, such Global Note may be transferred, in whole but not in part, and any payments on the Notes shall be made, only to DTC or a nominee of DTC, or to a successor Depositary selected or approved by the Bank or to a nominee of such successor Depositary.

Section 205 <u>Interest.</u>

The Notes shall bear interest on their principal amount (i) from, and including, the Issue Date to, but excluding, July 28, 2031 (the "**Initial Reset Date**"), at a fixed rate of 6.500% per annum, and (ii) from, and including, the Initial Reset Date, during each Rate Reset Period, at a rate per annum equal to the U.

The term "**interest period**" for the Notes means the period from, and including, any Interest Payment Date (or, with respect to the initial interest period only, commencing on the Issue Date) to, but excluding, the next succeeding Interest Payment Date, and in the case of the final such interest period, the Maturity (or, if applicable, the Redemption Date or repurchase date).

Interest on the Notes shall be calculated and paid on the basis of a 360-day year of twelve 30-day months. For the avoidance of doubt, interest payments shall not be deferrable.

Interest on the Notes shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by the United States law of general application. In no event shall the interest rate on the Notes be less than zero.

All percentages resulting from any calculation relating to a Note will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point, e.g., 9.876541% (or 0.09876541) being rounded down to 9.87654% (or 0.0987654) and 9.876545% (or 0.09876545) being rounded up to 9.87655% (or 0.0987655). All amounts used in or resulting from any calculation relating to a Note will be rounded upward or downward, as appropriate, to the nearest cent, in the case of U.S. dollars, or to the nearest corresponding hundredth of a unit, in the case of a currency other than U.S. dollars, with one-half cent or one-half of a corresponding hundredth of a unit or more being rounded upward.

Each calculation of the interest rate on the Notes will, in the absence of manifest error, be final and binding on holders of Notes, the Trustee, the Canadian Co-Trustee, the paying agent and the Bank. Any other determination, decision or selection that may be made by us or the Calculation Agent, pursuant to the provisions of the Notes (including provisions relating to a rate substitution event and any U.S. Treasury Rate adjustments, or of the occurrence or non-occurrence of an event, circumstance or date, and any decision to take or refrain from taking any action or make or refrain from making any selection) will be made in our or such agent's sole discretion, will be conclusive and binding absent manifest error and, notwithstanding anything to the contrary in this Indenture or the Notes, shall become effective without consent from the Holders of the Notes or any other party.

ARTICLE Five<br> REMEDIES

Section 501 <u>Applicability of Article Five of Base Indenture.</u>

For the avoidance of doubt, except as set forth in this Article Five, Article Five of the Base Indenture applies to the Notes.

Section 502 <u>Events of Default.</u>

Notwithstanding any other provisions of the Indenture or the Notes, and for the avoidance of doubt, none of (i) the non-payment of principal or interest on the Notes, (ii) a default in the performance of any other covenant of the Bank in the Indenture or (iii) the occurrence of a Trigger Event (including an NVCC Automatic Conversion) shall constitute an Event of Default under the Indenture or in respect of the Notes.

In addition, by acquiring any Note, each Holder and beneficial owner of such Note or any interest therein, including any Person acquiring any such Note or interest therein after the date hereof, is deemed to irrevocably acknowledge and agree with and for the benefit of the Bank and the Trustee and the Canadian Co-Trustee that a Trigger Event (including an NVCC Automatic Conversion) shall not give rise to an Event of Default or a default for purposes of Section 315(b) (*Notice of Default*) and Section 315(c) (*Duties of the Trustee in Case of Default*) of the Trust Indenture Act.

Section 503 <u>Recourse to Corresponding Trust Assets Is Sole Remedy.</u>

All claims of a Holder against the Bank under the Notes shall be extinguished upon receipt by such Holder of such Holder's proportionate share of the Corresponding Trust Assets. If the Limited Recourse Trustee fails to deliver, or the Bank fails to cause the Limited Recourse Trustee to deliver, a Holder's proportionate share of the Corresponding Trust Assets to such Holder, the sole remedy of such Holder for any claims against the Bank shall be recourse to such Holder's proportionate share of the Corresponding Trust Assets.

For the avoidance of doubt, the delivery of a Holder's proportionate share of the Corresponding Trust Assets to such Holder shall be deemed to be in full satisfaction of the Notes and shall exhaust all remedies of such Holder against the Bank. In the case of any shortfall resulting from the value of the Corresponding Trust Assets being less than the principal amount of and any accrued and unpaid interest on, or the Redemption Price of, the Notes held by such Holder, all losses arising from such shortfall shall be borne by such Holder and no claim may be made against the Bank."

Section 706 <u>Corporate Trustee Required; Eligibility.</u>

For purposes of the Notes, Section 609 of the Base Indenture is hereby replaced in its entirety as follows:

Any Trustee or co-trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $15,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 706 and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Notes shall cease to be eligible in accordance with the provisions of this Section 706, it shall resign immediately in the manner and with the effect hereinafter specified in Article Six of the Base Indenture.

For so long as required by Canadian Trust Indenture Legislation, there shall be a Canadian Co-Trustee with respect to the Notes under this Supplemental Indenture.

Unless the context implies or requires otherwise, any written notice, request, direction, certificate, instruction, opinion, Board Resolution or other document (each such document, a "Writing") delivered pursuant to any provision of this Indenture to the Trustee shall be deemed for all purposes of this Indenture as delivery of such Writing to the Trustee and the Canadian Co-Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) For avoidance of doubt, the provisions of Sections 610, 611 and 612 of the Base Indenture shall apply to the Canadian Co-Trustee. The Bank at any time, by an instrument in writing executed by it, may accept the resignation of, or remove, the Canadian Co-Trustee (or other co-trustee appointed by it) under the Indenture.

ARTICLE Eight<br> COVENANTS

Section 801 <u>Additional Amounts.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Bank will pay any and all amounts on the Notes without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("**taxes**") now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of Canada or any Canadian political subdivision or authority that has the power to tax ("**Canadian Taxes**"), unless the deduction or withholding is required by law or by the interpretation or administration thereof by the relevant governmental authority. At any time a Canadian taxing jurisdiction requires the Bank to deduct or withhold for or on account of Canadian Taxes from any payment made under or in respect of the Notes, the Bank will pay such additional amounts ("**Additional Amounts**") as may be necessary so that the net amounts received by each Holder (including Additional Amounts), after such deduction or withholding of Canadian Taxes, shall not be less than the amount the Holder would have received had no such deduction or withholding of Canadian Taxes been required.

However, no Additional Amounts will be payable with respect to a payment made to a Holder or a beneficial owner of a Note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) which does not deal at arm's length (for the purposes of the Tax Act) with the Bank at the time the amount is paid or payable or is, or does not deal at arm's length with any Person who is, a "specified shareholder" of the Bank for purposes of the thin capitalization rules in the Tax Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) which is subject to such Canadian Taxes by reason of the Holder or beneficial owner being a "specified entity" in respect of the Bank as defined in the rules in the Tax Act with respect to "hybrid mismatch arrangements";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) which is subject to such Canadian Taxes by reason of the Holder or beneficial owner thereof (or any fiduciary, settlor, beneficiary, member or shareholder of, or possessor of power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust, partnership, limited liability company or corporation) being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some present or former connection with Canada or any province or territory thereof otherwise than by the mere holding of the Notes or the receipt of payments thereunder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D) which is subject to such Canadian Taxes by reason of the Holder's or beneficial owner's failure to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes or is otherwise reasonably requested by us to support a claim for relief or exemption from such tax.

In addition, Additional Amounts will not be payable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(E) if the Holder of such Notes is not the sole beneficial owner of such payments, or is a fiduciary or partnership, to the extent that any beneficial owner, beneficiary or settlor with respect to such fiduciary or any partner or member of such partnership would not have been entitled to such Additional Amounts with respect to such payments had such beneficial owner, beneficiary, settlor, partner or member received directly its beneficial or distributive shares of such payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(F) with respect to any Canadian Taxes which are payable otherwise than by withholding from payments made under or in respect of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(G) with respect to any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or other governmental charge;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(H) with respect to any Canadian Taxes that would not have been imposed but for the presentation by the Holder of a Note for payment more than 30 days after the date on which such payment became due and payable or on which payment thereof was duly provided for, whichever occurs later;

&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) with respect to any Canadian Taxes required to be deducted or withheld by any paying agent from a payment on a Note, if such payment can be made without such deduction or withholding by any other paying agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(J) with respect to any tax, assessment, withholding or deduction imposed pursuant to Sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended, or any successor version thereof, or any similar legislation imposed by any other governmental authority (the "**Code**"), any agreements entered into pursuant to current Section 1471(b)(1) of the Code, and any fiscal or regulatory legislation adopted pursuant to any intergovernmental agreement, treaty, or convention among governmental authorities entered into in connection with the implementation of the foregoing, and including for greater certainty, Part XVIII and Part XIX of the Tax Act and any rules or practices adopted pursuant to any of them ("**FATCA**"), or any taxes or penalties that arise from the Holder or beneficial owner's failure to properly comply with its obligations with respect to FATCA or the Canada-United States Enhanced Tax Information Exchange Agreement Implementation Act (Canada); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(K) any combination of the items listed above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Bank will also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Bank will furnish to the Trustee, the Canadian Co-Trustee and Holders of the relevant Notes, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by the Bank to the relevant taxation authority.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Bank will indemnify and hold harmless each Holder (except in the circumstances where no Additional Amounts would be payable) from and against, and upon written request reimburse each such Holder for the amount (excluding any Additional Amounts that have previously been paid by the Bank with respect thereto) of: (a) any Canadian Taxes so levied or imposed and paid by such Holder as a result of payments of principal or interest made by or on behalf of the Bank under or with respect to the Notes; (b) any penalties and interest arising therefrom or with respect thereto; and (c) any Canadian Taxes imposed with respect to any reimbursement under (a) or (b), but excluding any such Canadian Taxes on such Holder's net income or capital.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) In any event, no Additional Amounts or indemnity amounts will be payable under the provisions described above in respect of any Note in excess of the Additional Amounts and the indemnity amounts which would be required if, at all relevant times, the beneficial owner of such Note were a resident of the United States for purposes of, and was entitled to all of the benefits of the Canada-U.S. Income Tax Convention (1980), as amended, including any protocols thereto. As a result of the limitation on the payment of Additional Amounts and indemnity amounts discussed in the preceding sentence of this Section 801(5), the Additional Amounts or indemnity amounts received by certain Holders or beneficial owners of the Notes may be less than the amount of Canadian Taxes withheld or deducted or the amount of Canadian Taxes (and related amounts) levied or imposed, as the case may be, and, accordingly, the net amount received by such Holders of those Notes will be less than the amount such Holders would have received had there been no such withholding or deduction in respect of Canadian Taxes or had such Canadian Taxes (and related amounts) not been levied or imposed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Wherever in the Indenture there is mentioned, in any context, the payment of principal or interest or any other amount payable under or with respect to a Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable as set forth in this Section 801.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) In the event of the occurrence of any transaction or event resulting in a successor to the Bank, all references to Canada in the preceding paragraphs of this subsection shall be deemed to be references to the jurisdiction of organization of the successor entity.

Section 802 <u>No Restriction on Other Indebtedness.</u>

The Bank may create, issue or incur any other Indebtedness which, in the event of the insolvency or winding-up of the Bank, would rank in right of payment in priority to, equally with, or subordinate to the Notes.

Notwithstanding any other provision in the Indenture, the sole remedy of Holders in the event of a Recourse Event (including, for the avoidance of doubt, the non-payment of the principal amount of, interest on or the Redemption Price for the Notes when due or the occurrence of a Trigger Event) shall be recourse to the Corresponding Trust Assets. Upon any such Recourse Event, the principal amount of, and accrued and unpaid interest (if any) on, the Notes will become due and payable without any declaration or other act on the part of the Trustee, the Canadian Co-Trustee or any Holders; *provided* that recourse for such principal amount and accrued and unpaid interest shall be solely to the Corresponding Trust Assets. The delivery to a Holder of such Holder's proportionate share of the Corresponding Trust Assets shall exhaust all remedies of such Holder under the Notes in connection with any Recourse Event. All claims of a Holder against the Bank shall be extinguished upon receipt by such Holder of such Holder's proportionate share of the Corresponding Trust Assets. The delivery of a Holder's proportionate share of the Corresponding Trust Assets to such Holder shall be deemed to be in full satisfaction of the Notes and shall exhaust all remedies of such Holder against the Bank in accordance with Section 503 regardless of whether the value of such Corresponding Trust Assets is less than the principal amount of and any accrued and unpaid interest on the Notes or the Redemption Price of the Notes, as applicable. Upon the distribution of the Corresponding Trust Assets to the Holders, the Bank will instruct the Trustee to cancel the corresponding Notes.

Section 902 <u>Corresponding Trust Assets.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) In connection with the issuance of the Notes, the Bank will cause the Limited Recourse Trustee to hold Corresponding Trust Assets in the Limited Recourse Trust, that will, on the Issue Date, consist of 700,000 Preferred Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) From and after the Issue Date, in the event of a Recourse Event, each Holder will be entitled to receive from the Limited Recourse Trustee, such Holder's proportionate share of the Corresponding Trust Assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Upon the occurrence of a Recourse Event that is a Trigger Event and immediately following an NVCC Automatic Conversion, each Holder will be entitled to receive from the Limited Recourse Trustee, such Holder's proportionate share of the Corresponding Trust Assets (subject to Section 903) (which shall be the fully-paid and non-assessable Common Shares (other than any Dividend Common Shares) then held in the Limited Recourse Trust pursuant to an NVCC Automatic Conversion).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) In accordance with the Limited Recourse Trust Declaration and subject to the provisions thereof, the Bank shall not permit the Limited Recourse Trustee to distribute any Corresponding Trust Assets other than (i) cash that does not constitute proceeds of a Preferred Share Redemption or purchase for cancellation of Preferred Shares (other than any portion of such proceeds in respect of any accrued and unpaid dividends), and (ii) in connection with the redemption or cancellation of any Notes or the redemption of the Preferred Shares pursuant to any Preferred Share Redemption. Notwithstanding the foregoing, the Limited Recourse Trustee shall remain free to distribute the Corresponding Trust Assets to Holders upon a Recourse Event and to distribute, at any time, to the Bank as sole unitholder of the Limited Recourse Trust (a) any dividends declared and paid on the Preferred Shares while held by the Limited Recourse Trustee, (b) the proceeds of the sale of any Dividend Common Shares issued to the Limited Recourse Trustee upon an NVCC Automatic Conversion, and (c) cash received upon any Preferred Share Redemption in respect of any accrued and unpaid dividends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) If a Recourse Event occurs, the Bank will, no later than one Business Day after the occurrence of such Recourse Event, notify the Limited Recourse Trustee and the Trustee and the Canadian Co-Trustee in writing of the occurrence of such Recourse Event, and the Bank will take any necessary actions to cause the Limited Recourse Trustee to deliver to each Holder such Holder's proportionate share of the Corresponding Trust Assets in accordance with the terms of the Limited Recourse Trust Declaration and the Indenture.

Section 903 <u>Right Not to Deliver Common Shares or Preferred Shares.</u>

Notwithstanding any other provision in the Indenture or the Limited Recourse Trust Declaration, the Bank reserves the right not to (i) deliver Common Shares or Preferred Shares to any Person whom the Bank or its stock transfer agent has reason to believe is an Ineligible Person or any Person who, by virtue of that delivery, would become a Significant Shareholder or (ii) record in its securities register a transfer or issue of Common Shares or Preferred Shares to any person whom the Bank or its stock transfer agent has reason to believe is an Ineligible Government Holder based on a declaration submitted to the Bank or its stock transfer agent by or on behalf of such person. In such circumstances, the Bank or its stock transfer agent will hold, as agent for such Persons, the Common Shares or Preferred Shares that would have otherwise been delivered to such Persons and will attempt to facilitate the sale of such Common Shares or Preferred Shares to parties other than the Limited Recourse Trust or the Bank and its Affiliates on behalf of such Persons through a registered dealer to be retained by the Bank on behalf of such Persons. Those sales (if any) may be made at any time and at any price as the Bank (or its stock transfer agent as directed by the Bank), in its sole discretion, may determine. Neither the Bank nor its stock transfer agent shall be subject to any liability for failure to sell any such Common Shares or Preferred Shares on behalf of such Persons or at any particular price on any particular day. The net proceeds received by the Bank or its stock transfer agent from the sale of any such Common Shares or Preferred Shares will be divided among the applicable Persons in proportion to the number of Common Shares or Preferred Shares that would otherwise have been delivered to any such Person after deducting the costs of sale and any applicable withholding taxes. The Bank shall deliver a check or send a wire transfer in immediately available funds representing the aggregate net proceeds to the Depository (if the Common Shares or Preferred Shares are then held in the form of one or more global securities) or in all other cases to such Persons in accordance with the regular practices and procedures of the Depository or otherwise.

Section 904 <u>Trigger Event.</u>

Upon the occurrence of a Trigger Event and immediately following an NVCC Automatic Conversion, the Corresponding Trust Assets will consist of Common Shares, and each Holder will be entitled to receive from the Limited Recourse Trustee, such Holder's proportionate share of the Corresponding Trust Assets (excluding, for the avoidance of doubt, any Dividend Common Shares), subject to Section 903.

Section 905 <u>Conversion Rate.</u>

The number of Common Shares that will be held in the Limited Recourse Trust following an NVCC Automatic Conversion and immediately before the delivery of the Common Shares (other than any Dividend Common Shares) to Holders will be equal to the product of (a) the number of Preferred Shares held in the Limited Recourse Trust immediately prior to an NVCC Automatic Conversion, times (b) the quotient obtained by dividing (i) the Multiplier multiplied by the Share Value, by (ii) the Conversion Price (rounding down, if necessary to the nearest whole number of Common Shares). For the purposes of this Section 905, the terms "Multiplier," "Share Value" and "Conversion Price" shall have the respective meanings ascribed to them in the terms and conditions applicable to the Preferred Shares.

Each Holder shall receive the number of Common Shares (subject to Section 903 and excluding any Dividend Common Shares) in proportion to the principal amount of the Outstanding Notes held by each Holder. For the avoidance of doubt, any accrued and unpaid interest will not be taken into account.

Section 906 <u>Time of Delivery.</u>

The delivery of the Common Shares is deemed to be effected immediately following the occurrence of an NVCC Automatic Conversion and the Person or Persons entitled to receive Corresponding Trust Assets (which shall be the fully-paid and non-assessable Common Shares then held in the Limited Recourse Trust pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)) upon a Recourse Event that is a Trigger Event shall be treated for all purposes as having become the holder or holders of record of such Common Shares at such time. Subject to Section 903, as promptly as practicable after the occurrence of a Trigger Event, the Bank shall announce the applicable Recourse Event by way of a press release and shall give notice (a "**Trigger Event Notice**") of the delivery of the Common Shares in accordance with the provisions of Section 106 of the Base Indenture to the Holders, the Trustee and the Canadian Co-Trustee. Immediately following the NVCC Automatic Conversion, any certificates representing the Notes shall represent the right to receive upon surrender thereof the applicable number of Common Shares as specified in Section 905. The provisions hereof shall be mandatory and binding upon the Bank, the Trustee, the Canadian Co-Trustee and all Holders notwithstanding anything else including, without limitation: (i) the existence or prior occurrence of an Event of Default in respect of the Notes; (ii) any prior action to or in furtherance of a redeeming, exchanging or converting the Notes pursuant to the other terms and conditions of the Indenture and (iii) any delay or impediment to the issuance of the Common Shares pursuant to an NVCC Automatic Conversion or the delivery of the Common Shares to the Holders.

Section 907 <u>Trigger Event Procedure.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If the Notes are held in the form of one or more Global Notes at the time of the Trigger Event, within two Business Days of its receipt of the Trigger Event Notice, the Trustee shall, acting pursuant to the Indenture, cause such notice to be transmitted to DTC to be delivered by DTC to its direct participants holding the Notes at such time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If the Notes are held in definitive form at the time of the Trigger Event, the Bank will deliver to Holders a notice describing, among other things, how the Bank intends to cause the Limited Recourse Trustee to deliver the evidence of beneficial ownership of the Common Shares and requesting such Holders to provide the Bank with their relevant securities account information for purposes of receiving such evidence of beneficial ownership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Bank shall have no liability to any Holder or beneficial owner of the Notes from any delay in the receipt of the evidence of beneficial ownership of the Common Shares resulting from the Bank's compliance with applicable operational and legal requirements.

Section 908 <u>Duties of Trustee and Canadian Co-Trustee Upon Trigger Event.</u>

Upon receipt by Holders of their proportionate share of the Corresponding Trust Assets from the Limited Recourse Trustee, neither the Trustee nor the Canadian Co-Trustee shall be required to take any further directions from Holders or beneficial owners of the Notes under the Indenture. The Indenture shall impose no duties upon the Trustee or the Canadian Co-Trustee whatsoever with respect to any calculations in connection with an NVCC Automatic Conversion or delivery of Common Shares upon a Trigger Event (except for the delivery of a notice by the Trustee to DTC following a Trigger Event pursuant to Section 907).

Section 909 <u>General.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The delivery to a Holder of its proportionate share of the Corresponding Trust Assets (which shall be fully-paid and non-assessable Common Shares then held by the Limited Recourse Trustee pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)) shall exhaust all remedies of such Holder under the Notes including in connection with any Trigger Event. All claims of a Holder against the Bank shall be extinguished upon receipt by such Holder of the applicable Common Shares. If tax is required to be withheld from such delivery of Common Shares, the number of Common Shares received by a Holder shall reflect an amount net of any applicable withholding tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Notwithstanding any other provision of the Indenture or the Notes, the Trigger Event and the delivery of Common Shares to the Holders pursuant to the provisions hereof shall not be an Event of Default and the only consequence of a Trigger Event shall be the right of the Holders to receive the Corresponding Trust Assets (which shall be the fully-paid and non-assessable Common Shares then held by the Limited Recourse Trustee pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Neither the Trustee nor the Canadian Co-Trustee shall have a duty to determine the occurrence of a Trigger Event or any calculations in connection with such Trigger Event. Neither the Trustee nor the Canadian Co-Trustee make any representation as to the validity or value of any securities or assets delivered upon a Trigger Event, and the Trustee and the Canadian Co-Trustee shall not be responsible for the Bank's failure to comply with any provisions of this Article Nine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Notwithstanding any other provision of the Indenture or the Notes, a failure to provide any notice referred to in Section 906, Section 907 or Section 908, shall not have any impact on the effectiveness of, or otherwise invalidate, any of the recourse mechanics described in the Indenture, or give the Holders and beneficial owners of the Notes any rights as a result of such failure.

Section 910 <u>Agreements of Holders and Beneficial Owners of Notes.</u>

By acquiring any Note, each Holder and beneficial owner of such Note or any interest therein, including any Person acquiring any such Note or interest therein after the date hereof, shall be deemed to have irrevocably acknowledged and agreed with and for the benefit of the Bank and the Trustee and the Canadian Co-Trustee as fo**l**lows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) that the delivery of the Holder's proportionate share of the Corresponding Trust Assets to such Holder shall exhaust all remedies of such Holder against the Bank under the Notes, including in connection with any Recourse Event that is a Trigger Event, and all claims of a Holder against the Bank shall be extinguished upon receipt by such Holder of such Holder's proportionate share of the Corresponding Trust Assets (which shall be the fully-paid and non-assessable Common Shares then held by the Limited Recourse Trustee pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)) upon the occurrence of a Recourse Event that is a Trigger Event, which occurrence and resulting delivery of Common Shares shall occur without any further action on the part of such Holder or beneficial owner or the Trustee or the Canadian Co-Trustee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) that the delivery of Common Shares or the occurrence of a Trigger Event shall not constitute an Event of Default under the terms of the Notes or the Indenture, and upon receipt by Holders of their proportionate share of the Corresponding Trust Assets, no Holder or beneficial owner of the Notes shall have any rights against the Bank with respect to the repayment of the principal of, or interest on, the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) that, (i) upon receipt by Holders of their proportionate share of the Corresponding Trust Assets, neither the Trustee nor the Canadian Co-Trustee shall be required to take any further directions from Holders or beneficial owners of the Notes under the Indenture and (ii) the Indenture shall impose no duties upon the Trustee or the Canadian Co-Trustee whatsoever with respect to the delivery of the Corresponding Trust Assets (which shall be the fully-paid and non-assessable Common Shares then held by the Limited Recourse Trustee pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)) immediately following a Trigger Event (except for the delivery of a notice by the Trustee to DTC following a Trigger Event pursuant to Section 907);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) that such Holder or beneficial owner authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Notes to take any and all necessary action, if required, to implement the delivery of the Corresponding Trust Assets (which shall be the fully-paid and non-assessable Common Shares then held in the Limited Recourse Trust pursuant to an NVCC Automatic Conversion (other than any Dividend Common Shares)) immediately following a Trigger Event without any further action or direction on the part of such Holder or such beneficial owner or the Trustee or the Canadian Co-Trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) that such Holder or beneficial owner acknowledges and agrees that all authority conferred or agreed to be conferred by any Holder and beneficial owner pursuant to the provisions described above shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of each Holder and beneficial owner of a Note or any interest therein.

Section 911 <u>Amendments to Limited Recourse Trust Declaration.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Any amendment or supplemental declaration of trust for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Limited Recourse Trust Declaration shall require the consent of the Majority Holders with notice to the Trustee and the Canadian Co-Trustee; *provided*, *however*, that to the extent any such addition, change or elimination is in respect of the definition of "Trust Assets" in Section 1.1 (Definitions), Section 2.3 (Objective of the Trust), Section 2.4 (Ownership of Trust Assets), Section 2.5 (Binding Effect), Section 2.6 (Legal Character of Trust), Section 10.6 (Acquisition and Administration of Trust Assets) and Article 14 (Termination) of the Limited Recourse Trust Declaration (or the equivalent sections of the Limited Recourse Trust Declaration following any addition, change or elimination to the Limited Recourse Trust Declaration permitted in accordance with this Section 911), such addition, change or elimination shall not be made without the consent of the Holder of each Outstanding Note affected thereby. For certainty, a change to the governing law of the Limited Recourse Trust Declaration in accordance with the provisions of the Limited Recourse Trust Declaration shall not require the consent of any Holders. It shall not be necessary for any Act of Holders under this Section 911(1) to approve the particular form of any proposed amendment or supplemental declaration of trust, but it shall be sufficient if such Act shall approve the substance thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Notwithstanding Section 911(1), without the consent of any Holders, the Limited Recourse Trustee may make any amendment to the Limited Recourse Trust Declaration or enter into supplemental declarations of trust to the Limited Recourse Trust Declaration for any of the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to evidence and provide for the acceptance of appointment by a successor Limited Recourse Trustee; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to cure any ambiguity, to correct or supplement any provision of the Limited Recourse Trust Declaration which may be defective or inconsistent with any other provision of the Limited Recourse Trust Declaration, to add, amend, correct or supplement any provision of the Limited Recourse Trust Declaration which may become incorrect or inaccurate as a result of the passage of time (including changes to the provisions of legislation referred to in the Limited Recourse Trust Declaration) or to make any other provisions with respect to matters or questions arising under the Limited Recourse Trust Declaration, *provided* that such action pursuant to this Section 911(2) shall not adversely affect the interests of the Holders in any material respect.

ARTICLE Ten<br> SUBORDINATION OF NOTES

Section 1001 <u>Applicability of Article Fifteen of Base Indenture.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) For the avoidance of doubt, the provisions of Article Fifteen of the Base Indenture shall be applicable to the Notes, except as modified herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Solely for purposes of the Notes (and not in relation to any other series of Securities), all references in Article Fifteen of the Base Indenture to "Senior Indebtedness" shall hereby be replaced with references to "Higher Ranked Indebtedness."

Section 1002 <u>Notes Subordinate to Deposit Liabilities and Other Indebtedness.</u>

For purposes of the Notes, Section 1501 of the Base Indenture is hereby replaced in its entirety as follows:

"The Notes are direct unsecured debt obligations constituting subordinated indebtedness within the meaning of the Bank Act and, in the event of the insolvency or winding-up of the Bank, the Indebtedness evidenced by the Notes shall rank:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) subordinate in right of payment to the prior payment in full of all Higher Ranked Indebtedness; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) in right of payment equally with and not prior to the Junior Subordinated Indebtedness (other than the Junior Subordinated Indebtedness which by its terms ranks subordinate to the Notes),

in each case, whether now outstanding or hereinafter incurred.

Notwithstanding the foregoing, in the event of the occurrence of a Recourse Event, including an Event of Default, the sole remedy of a Holder of the Notes shall be recourse to such Holder's proportionate share of the Corresponding Trust Assets.

The Bank agrees and each Holder and beneficial owner of any Note, by his, her or its acceptance of such Note, also agrees and shall be deemed conclusively to have agreed, for the benefit of the present and future holders of Higher Ranked Indebtedness, and for the benefit of all present and future holders of Indebtedness to which the Notes are subordinate in right of payment, to the provisions of this Article Ten and Article Fifteen of the Base Indenture and the Bank and each Holder of any Note by his, her or its acceptance of such Note shall be bound by such provisions."

ARTICLE Eleven<br> REDEMPTION OF NOTES

Section 1101 <u>Applicability of Article Eleven of the Base Indenture.</u>

For the avoidance of doubt, the provisions of Article Eleven of the Base Indenture shall be applicable to the Notes, except as modified herein.

In addition, for purposes of the Notes, Section 1101 of the Base Indenture is hereby replaced in its entirety as follows:

"Subject to any applicable law restricting the redemption of the Notes, including the Bank Act and the regulations and guidelines thereunder, including the CAR Guideline, and provided that a Trigger Event has not occurred, the Notes shall be redeemable in accordance with this Article Eleven. For certainty, the Bank will not redeem the Notes under any circumstances if such redemption would, directly or indirectly, result in the Bank's breach of any provision of the Bank Act or the CAR Guideline, as may be amended from time to time.

Subject to any law restricting the redemption of the Securities, Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article."

Section 1102 <u>Regulatory or Tax Redemption.</u>

The Bank may, with the prior written approval of the Superintendent and without the consent of the Holders of the Notes, redeem the Notes, in whole but not in part, on not less than 10 days' and not more than 60 days' prior notice to the Holders of the Notes, (i) at any time following a Regulatory Event Date, or (ii) at any time following the occurrence of a Tax Event Date, in each case at the Redemption Price (a "**Special Event Redemption**").

From and after the date of the Special Event Redemption, any Outstanding Notes so redeemed shall cease to be outstanding, the Holders thereof shall cease to be entitled to interest thereon, and any certificates representing the Notes shall represent only the right to receive, upon surrender thereof, the Redemption Price.

Section 1103 <u>Optional Redemption.</u>

The Bank may, at its option, with the prior written approval of the Superintendent and without the consent of the Holders, redeem the Notes, in whole or in part from time to time, on not less than 10 days' and not more than 60 days' prior notice to the Holders of the Notes, on the Initial Reset Date and on each January 28, April 28, July 28, and October 28 thereafter, at the Redemption Price (an "**Optional Redemption**").

From and after the date of the Optional Redemption, any Outstanding Notes so redeemed shall cease to be outstanding, the Holders thereof shall cease to be entitled to interest thereon, and any certificates representing the Notes shall represent only the right to receive, upon surrender thereof, the Redemption Price.

Section 1104 <u>Mandatory Redemption Upon Redemption of the Preferred Shares.</u>

Upon the occurrence of a Preferred Share Redemption on any date other than the Stated Maturity (such redemption will be subject to the prior written approval of the Superintendent), a corresponding number of Outstanding Notes with an aggregate principal amount equal to the aggregate face amount of Preferred Shares redeemed by the Bank pursuant to the Preferred Share Redemption shall automatically and immediately be redeemed, on a full and permanent basis, for a cash amount equal to the Redemption Price (a "**Mandatory Redemption**"), without any action on the part of, or the consent of, the Holders or beneficial owners. For certainty, to the extent that, in accordance with the terms of the Indenture, the Bank has immediately prior to or concurrently with such Preferred Share Redemption redeemed or purchased for cancellation Outstanding Notes with an aggregate principal amount equal to the aggregate face amount of Preferred Shares being redeemed, such requirement to redeem a corresponding aggregate principal amount of Notes shall be deemed satisfied.

From and after the date of a Mandatory Redemption, any Outstanding Notes so redeemed shall cease to be outstanding, the Holders thereof shall cease to be entitled to interest thereon, and any certificates representing the Notes shall represent only the right to receive, upon surrender thereof, the Redemption Price.

Section 1105 <u>Purchase for Cancellation.</u>

At any time, the Bank may, with the prior written approval of the Superintendent, purchase Notes, in whole or in part, in the open market or by tender (available to all Holders of Notes), by private contract or otherwise at such price or prices and upon such terms and conditions as the Bank in its absolute discretion may determine, subject, however, to any applicable law restricting the purchase of Notes. Any Notes purchased by the Bank shall be cancelled. Notwithstanding the foregoing, any subsidiary of the Bank may purchase Notes in the ordinary course of its business of dealing in securities.

If any Notes are so purchased for cancellation, subject to the provisions of the Bank Act, the consent of the Superintendent and various restrictions on the retirement of Preferred Shares, the Bank shall redeem a corresponding number of Preferred Shares (which Preferred Shares will have a face amount equal to the aggregate principal amount of the Notes to be cancelled) then held in the Limited Recourse Trust for cancellation.

Section 1106 <u>Redemption Obligations.</u>

Except as provided in this Article Eleven, the Bank shall not be required to make mandatory redemption payments or sinking fund payments with respect to the Notes.

Section 1107 <u>Redemption Generally.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If the Bank does not pay the applicable Redemption Price in cash when required, a Recourse Event will have occurred and each Holder of the Notes' sole remedy shall be the delivery of such Holder's proportionate share of the Corresponding Trust Assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Bank will not redeem the Notes under any circumstance if such redemption would, directly or indirectly, result in the Bank's breach of any provision of the Bank Act or CAR Guideline, as may be amended from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Any Notes redeemed by the Bank will be cancelled and will not be reissued.

Section 1108 <u>Notice of Redemption.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The occurrence of a Trigger Event prior to the Redemption Date shall automatically rescind a notice of redemption and, in such circumstances, no Notes shall be redeemed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Notwithstanding any other provision of the Indenture or the Notes, a failure to provide any notice (except for the notice in Section 1103 of the Base Indenture) referred to in Article Eleven of the Base Indenture or this Article Eleven shall not have any impact on the effectiveness of, or otherwise invalidate, any redemption, or give the Holders and beneficial owners of the Notes any rights as a result of such failure.

Section 1109 <u>Agreements of Holders and Beneficial Owners of Notes.</u>

By acquiring any Note, each Holder and beneficial owner of such Note or any interest therein, including any Person acquiring any such Note or interest therein after the date hereof, shall be deemed to have irrevocably acknowledged and agreed with and for the benefit of the Bank and the Trustee and the Canadian Co-Trustee as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) that upon the occurrence of any redemption of Notes, such redemption shall, in each case, occur without any further action on the part of such Holder or beneficial owner; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) that the occurrence of any redemption of Notes shall not constitute an Event of Default under the terms of the Notes or the Indenture, and following such redemption, Holders and beneficial owners of the Notes will not have any rights against the Bank with respect to the repayment of the principal amount of, or interest on, the Notes other than if the Redemption Price is not paid in cash as required, in which case the recourse of Holders is limited to receiving the Corresponding Trust Assets.

Canadian Imperial Bank of Commerce, a Schedule I bank under the *Bank Act* (Canada) (herein called the "**Bank**", which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or its registered assigns, as nominee of The Depository Trust Company, the principal sum of US$[ ] ([ ] MILLION AND 00/100 U.S. DOLLARS) on July 28, 2086 (the "**Stated Maturity**"), and to pay interest thereon (a) from, and including, January 13, 2026 to, but excluding, July 28, 2031 (the "**Initial Reset Date**"), at a fixed rate of 6.500% per annum, and (b) during each period from, and including, the Initial Reset Date to, but excluding, the next Interest Reset Date and each five year period thereafter from, and including, such Interest Reset Date to, but excluding, the next Interest Reset Date or the Stated Maturity, as applicable (each such period, a "**Rate Reset Period**"), at a rate per annum equal to the U.S. Treasury Rate on the Interest Rate Calculation Date immediately preceding the applicable Interest Reset Date plus 2.727%. For each Rate Reset Period, the U.S. Treasury Rate shall be determined by the Calculation Agent on the third Business Day immediately preceding the applicable Interest Reset Date (each such date, a "**Interest Rate Calculation Date**"). Interest on this Security will be payable quarterly in arrears on January 28, April 28, July 28, and October 28 of each year (each, an "**Interest Payment Date**"), commencing on April 28, 2026. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture referred to herein, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date (as defined below) for such interest, *provided* that the interest due at the Stated Maturity or, if this Security is redeemed, the Redemption Date, will be paid to the Person to whom principal is payable. The "**Regular Record Date**" means the close of business on the day immediately preceding each Interest Payment Date (or if this Security is held in definitive form, the 15th calendar day preceding each Interest Payment Date, whether or not a Business Day). A "**Business Day**" means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or obligated by law or executive order to close in the city of New York, New York or Toronto, Ontario. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holders of the Securities not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the Bank shall postpone the making of such interest or principal payment to the next succeeding Business Day (and no interest thereon shall be paid in respect of the delay).

Ex. A-1

Payment of the principal of and interest on this Security shall be made at the office or agency of the Bank maintained for that purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; *provided* that at the option of the Bank payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; *provided further* that payment of the principal of and interest on the Securities represented by one or more Global Securities registered in the name of or held by DTC or its nominee shall be payable in immediately available funds to DTC or its nominee, as the case may be, as the registered Holder of such Global Security (or pursuant to the applicable procedures of DTC).

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

**(REVERSE OF SECURITY)**

CANADIAN IMPERIAL BANK OF COMMERCE

6.500% Fixed Rate Reset Limited Recourse Capital Notes Series 9<br> (Non-Viability Contingent Capital (NVCC)) (Subordinated Indebtedness)

This Security is one of a duly authorized issue of securities of the Bank (herein called the "**Securities**"), issued and to be issued in one or more series under the Indenture, dated as of November 5, 2024 (herein called the "**Base Indenture**," which term shall have the meaning assigned to it in such instrument), between the Bank and The Bank of New York Mellon, as trustee (the "**Trustee**," which term includes any successor trustee under the Indenture), security registrar and paying agent, as amended and supplemented by the Third Supplemental Indenture, dated as of January 13, 2026, between the Bank, the Trustee and Computershare Advantage Trust of Canada, as Canadian co-trustee (the "**Canadian Co-Trustee**," which term includes any successor co-trustee under the Indenture) (the "**Supplemental Indenture**" and, together with the Base Indenture, the "**Indenture**"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Bank, the Trustee, the Canadian Co-Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to US$700,000,000.

This Security is a Global Security representing US$[ ] aggregate principal amount of Securities.

The indebtedness evidenced by this Security is a direct unsecured obligation constituting subordinated indebtedness within the meaning of the Bank Act and, in the event of the insolvency or winding-up of the Bank, the indebtedness evidenced by this Security shall rank (1) subordinate in right of payment to the prior payment in full of all Higher Ranked Indebtedness and (2) in right of payment equally with and not prior to Junior Subordinated Indebtedness (other than the Junior Subordinated Indebtedness which by its terms ranks subordinate to the Securities), in each case, from time to time outstanding. Notwithstanding the foregoing, in the event of the occurrence of a Recourse Event, including an Event of Default, the sole remedy of the Holders shall be recourse to the Corresponding Trust Assets. Each Holder, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee and the Canadian Co-Trustee on his, her or its behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee and the Canadian Co-Trustee as his or her attorney-in-fact for any and all such purposes. Each Holder, by his or her acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Higher Ranked Indebtedness whether now outstanding or hereafter created, incurred, assumed or guaranteed, and waives reliance by such holder upon said provisions.

The Bank may, at its option, with the prior written approval of the Superintendent and without the consent of the Holders, redeem the Securities, on not less than 10 days' and not more than 60 days' prior notice to the Holders, in whole or in part from time to time, on the Initial Reset Date and on each January 28, April 28, July 28, and October 28 thereafter, in each case at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date (the "**Redemption Price**").

The Bank may, with the prior written approval of the Superintendent and without the consent of the Holders, on not less than 10 days' and not more than 60 days' prior notice to the Holders, redeem this Security, in whole but not in part, (i) at any time following a Regulatory Event Date, or (ii) at any time following the occurrence of a Tax Event Date, in each case at the Redemption Price.

Upon any redemption by the Bank of the Preferred Shares held in the Limited Recourse Trust in accordance with the terms of such Preferred Shares prior to the Stated Maturity (such redemption will be subject to the prior written approval of the Superintendent), Outstanding Securities with an aggregate principal amount equal to the aggregate face amount of Preferred Shares redeemed by the Bank pursuant to such redemption shall automatically and immediately be redeemed, for a cash amount equal to the Redemption Price, on a full and permanent basis, without any action on the part of, or the consent of, the Holders or beneficial owners of the Securities. For certainty, to the extent that, in accordance with the terms of the Indenture, the Bank has immediately prior to or concurrently with such redemption of Preferred Shares redeemed or purchased for cancellation Securities with an aggregate principal amount equal to the aggregate face amount of Preferred Shares being redeemed, the foregoing requirement to redeem a corresponding aggregate principal amount of Securities shall be deemed satisfied.

Ex. A-5

Notwithstanding the foregoing, installments of interest on this Security that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant record date according to this Security and the Indenture.

On and after the redemption date, interest will cease to accrue on this Security or any portion of this Security called for redemption, unless the Bank defaults in the payment of the redemption price and accrued interest.

At any time or from time to time the Bank may, with the prior written approval of the Superintendent, purchase Securities, in whole or in part, in the open market (including by private contracts), by tender or otherwise in accordance with applicable securities laws and regulations, so long as such acquisition does not otherwise violate the terms of the Indenture, upon such terms and at such prices as the Bank may determine.

The Bank will pay any and all amounts on this Security without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("**taxes**") now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of Canada or any Canadian political subdivision or authority that has the power to tax ("**Canadian Taxes**"), unless the deduction or withholding is required by law or by the interpretation or administration thereof by the relevant governmental authority. At any time a Canadian taxing jurisdiction requires the Bank to deduct or withhold for or on account of Canadian Taxes from any payment made under or in respect of this Security, the Bank will pay such additional amounts ("**Additional Amounts**") as may be necessary so that the net amounts received by each Holder (including Additional Amounts), after such deduction or withholding of Canadian Taxes, shall not be less than the amount the Holder would have received had no such deduction or withholding of Canadian Taxes been required. However, no Additional Amounts will be payable with respect to a payment made to a Holder or the beneficial owner: (a) which does not deal at arm's length (for the purposes of the *Income Tax Act* (Canada)) with the Bank at the time the amount is paid or payable or is, or does not deal at arm's length with any person who is, a "specified shareholder" of the Bank for purposes of the thin capitalization rules in the *Income Tax Act* (Canada); (b) which is subject to such Canadian Taxes by reason of the Holder or beneficial owner being a "specified entity" in respect of the Bank as defined in the rules in the *Income Tax Act* (Canada) with respect to "hybrid mismatch arrangements"; (c) which is subject to such Canadian Taxes by reason of the Holder or beneficial owner thereof (or any fiduciary, settlor, beneficiary, member or shareholder of, or possessor of power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust, partnership, limited liability company or corporation) being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some present or former connection with Canada or any province or territory thereof otherwise than by the mere holding of the Securities or the receipt of payments thereunder; or (d) which is subject to such Canadian Taxes by reason of the Holder's or beneficial owner's failure to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes or is otherwise reasonably requested by the Bank to support a claim for relief or exemption from such tax. In addition, Additional Amounts will not be payable: (a) if the Holder is not the sole beneficial owner of such payments, or is a fiduciary or partnership, to the extent that any beneficial owner, beneficiary or settlor with respect to such fiduciary or any partner or member of such partnership would not have been entitled to such Additional Amounts with respect to such payments had such beneficial owner, beneficiary, settlor, partner or member received directly its beneficial or distributive shares of such payments; (b) with respect to any Canadian Taxes which are payable otherwise than by withholding from payments made under or in respect of this Security; (c) with respect to any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or other governmental charge; (d) with respect to any Canadian Taxes that would not have been imposed but for the presentation by the Holder for payment more than 30 days after the date on which such payment became due and payable or on which payment thereof was duly provided for, whichever occurs later; (e) with respect to any Canadian Taxes required to be deducted or withheld by any paying agent from a payment on this Security, if such payment can be made without such deduction or withholding by any other paying agent; (f) with respect to any tax, assessment, withholding or deduction imposed pursuant to Sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended, or any successor version thereof, or any similar legislation imposed by any other governmental authority (the "**Code**"), any agreements entered into pursuant to current Section 1471(b)(1) of the Code, and any fiscal or regulatory legislation adopted pursuant to any intergovernmental agreement, treaty, or convention among governmental authorities entered into in connection with the implementation of the foregoing, and including for greater certainty, Part XVIII and Part XIX of the *Income Tax Act* (Canada) and any rules or practices adopted pursuant to any of them ("**FATCA**"), or any taxes or penalties that arise from the Holder or beneficial owner's failure to properly comply with its obligations with respect to FATCA or the Canada-United States Enhanced Tax Information Exchange Agreement Implementation Act (Canada); or (g) any combination of the items listed above.

Ex. A-6

The Bank will also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Bank will furnish to the Trustee, the Canadian Co-Trustee and the Holders, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by the Bank to the relevant taxation authority.

The Bank will indemnify and hold harmless each Holder (except in the circumstances where no Additional Amounts would be payable) from and against, and upon written request reimburse each such Holder for the amount (excluding any Additional Amounts that have previously been paid by the Bank with respect thereto) of: (a) any Canadian Taxes so levied or imposed and paid by such Holder as a result of payments of principal or interest made by or on behalf of the Bank under or with respect to this Security; (b) any penalties and interest arising therefrom or with respect thereto; and (c) any Canadian Taxes imposed with respect to any reimbursement under (a) or (b), but excluding any such Canadian Taxes on such Holder's net income or capital.

In any event, no Additional Amounts or indemnity amounts will be payable under the provisions described above in respect of this Security in excess of the Additional Amounts and the indemnity amounts which would be required if, at all relevant times, the beneficial owner of this Security were a resident of the United States for purposes of, and was entitled to all of the benefits of the United States-Canada Income Tax Convention (1980), as amended, including any protocols thereto. As a result of the limitation on the payment of Additional Amounts and indemnity amounts discussed in the preceding sentence, the Additional Amounts or indemnity amounts received by certain Holders may be less than the amount of Canadian Taxes withheld or deducted or the amount of Canadian Taxes (and related amounts) levied or imposed giving rise to the obligation to pay the indemnity amounts, as the case may be, and, accordingly, the net amount received by such Holders will be less than the amount such Holders would have received had there been no such withholding or deduction in respect of Canadian Taxes or had such Canadian Taxes (and related amounts) not been levied or imposed.

Wherever in the Indenture there is mentioned, in any context, the payment of principal or interest or any other amount payable under or with respect to this Security, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

In the event of the occurrence of any transaction or event resulting in a successor to the Bank, all references to Canada in the preceding paragraphs relating to Additional Amounts shall be deemed to be references to the jurisdiction of organization of the successor entity.

No sinking fund is provided for the Securities.

This Security is not subject to defeasance.

Ex. A-7

No Holder or beneficial owner of an interest in this Security may exercise, or direct the exercise, claim or plead any right of set-off, netting, compensation or retention in respect of any amount owed to it by the Bank arising under, or in connection with, this Security, and each Holder or beneficial owner of an interest in this Security shall, by virtue of its acquisition of this Security (or an interest therein), be deemed to have irrevocably and unconditionally waived all such rights of set-off, netting, compensation or retention. Notwithstanding the foregoing, if any amounts due and payable to any Holder or beneficial owner of an interest in this Security by the Bank in respect of, or arising under, this Security are purportedly discharged by set-off, netting, compensation or retention, without limitation to any other rights and remedies of the Bank under applicable law, such Holder or beneficial owner of an interest in this Security shall be deemed to receive an amount equal to the amount of such discharge and, until such time as payment of such amount is made, shall hold such amount in trust for the Bank and, accordingly, any such discharge shall be deemed not to have taken place and such set-off, netting, compensation or retention shall be ineffective.

Upon the occurrence of an Event of Default with respect to the Securities, the sole remedy of a Holder shall be recourse to such Holder's proportionate share of the Corresponding Trust Assets held in respect of this Security, and all claims of the Holder against the Bank under this Security shall be extinguished upon receipt of such Corresponding Trust Assets.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Bank and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Bank and the Trustee and, as applicable, the Canadian Co-Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected, or in certain cases the unanimous consent of each of such Holders. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Bank with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. The Indenture prohibits the Bank from amending or varying terms of this Security that would affect the recognition of this Security as regulatory capital under capital adequacy requirements adopted by the Superintendent without the prior written approval of the Superintendent.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Bank, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed, *provided* that, as provided in and subject to the provisions of the Indenture, the sole remedy of the Holder will be recourse to such Holder's proportionate share of the Corresponding Trust Assets held in respect of this Security. Delivery of Corresponding Trust Assets to the Holder shall be applied to the payment of the principal amount of this Security, and all claims of the Holder against the Bank will be extinguished upon receipt of the Corresponding Trust Assets.

Ex. A-8

As provided in and subject to the provisions of the Indenture, the Holder shall not have the right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (i) such Holder has previously given written notice to the Trustee and the Canadian Co-Trustee of a continuing Event of Default with respect to the Securities or a failure of the Limited Recourse Trustee to deliver such Holder's proportionate share of the Corresponding Trust Assets to such Holder; (ii) the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee and/or the Canadian Co-Trustee to institute proceedings in respect of such Event of Default or failure of the Limited Recourse Trustee to deliver the proportionate share of the Corresponding Trust Assets to a Holder, in one or both of the Trustee's and/or the Canadian Co-Trustee's own name as Trustee or Canadian Co-Trustee, as the case may be, under the Indenture; (iii) such Holder or Holders shall have offered to the Trustee and/or the Canadian Co-Trustee, as the case may be, full indemnity and/or security against reasonable costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee and/or the Canadian Co-Trustee, as the case may be, for 90 days after its receipt of such notice, request and offer of indemnity has not taken action to institute any such proceeding; and (v) no direction inconsistent with such written request has been given to the Trustee and/or the Canadian Co-Trustee, as the case may be, during such 90-day period by the majority in principal amount of Securities at the time Outstanding; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal and ratable benefit of all of such Holders.

For disclosure purposes under the *Interest Act* (Canada), whenever in the Securities or the Indenture interest at a specified rate is to be calculated on the basis of a period less than a calendar year, the yearly rate of interest to which such rate is equivalent is such rate multiplied by the actual number of days in the relevant calendar year and divided by the number of days in such period.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Bank in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Bank and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities and of like tenor, of authorized denominations and for the same aggregate principal amount, shall be issued to the designated transferee or transferees.

The Securities are issuable only in registered form without coupons in denominations of US$200,000 and integral multiples of US$1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

Any Holder that transfers any Security shall provide or cause to be provided to the Trustee and the Canadian Co-Trustee all information necessary to allow each of them to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. Each of the Trustee and the Canadian Co-Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

Ex. A-9

No service charge shall be made for any such registration of transfer or exchange, but the Bank or the Trustee or the Canadian Co-Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

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

No recourse for the payment of the principal or interest on this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Bank in the Indenture or any supplemental indenture thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Bank or of any successor corporation of either of them, either directly or through the Bank or any successor corporation of either of them, whether by virtue of any constitution, statute or rule or law or by the enforcement of any assessment or penalty or otherwise, all such liability being by the acceptance hereof and as a condition of and as part of the consideration for the issue hereof, expressly waived and released.

The following resale restriction is only applicable to residents of Canada who purchased this Security pursuant to a prospectus exemption under applicable Canadian securities laws: Unless permitted under securities legislation, the Holder must not trade this Security before May 14, 2026.

All terms used in this Security and not otherwise defined herein that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

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 (i) issuance and sale of US$700,000,000 aggregate principal amount of 6.500% Fixed Rate Reset Limited Recourse Capital Notes Series 9 (Non-Viability Contingent Capital (NVCC)) (Subordinated Indebtedness) (the "Notes") and (ii) issuance to Computershare Trust Company of Canada, as trustee of CIBC LRCN Limited Recourse Trust of 700,000 Non-Cumulative 5-Year Fixed Rate Reset Class A Preferred Shares Series 64 (Non-Viability Contingent Capital (NVCC)) (the "Preferred Shares"). CIBC filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act") 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 January 6, 2026 (the "Prospectus Supplement" and together with the "Base Prospectus," the "Prospectus"), relating to, among other things, the Notes. The Notes are being issued under an indenture, dated as of November 5, 2024 (the "Base Indenture"), between CIBC and The Bank of New York Mellon (the "Trustee"), as supplemented by a third supplemental indenture, dated as of January 13, 2026, among CIBC, the Trustee and Computershare Advantage Trust of Canada, as Canadian co-trustee (the "Supplemental Indenture" and, together with the Base Indenture, the "Indenture"). The Preferred Shares will be convertible into common shares of CIBC upon a Trigger Event and resulting NVCC Automatic Conversion (as such terms are defined in the provisions attaching to the Preferred Shares).

In connection with our representation, we have examined (i) the Registration Statement, (ii) the Prospectus, (iii) an executed copy of the Indenture, (iv) the form of certificate representing the Notes 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.

&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 Notes 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 Notes 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) and Article Fifteen of the Base Indenture and Sections 903, 904, 905, 906, 909, 910 and 1002 of the Supplemental Indenture, each of which is governed by the laws of the Province of Ontario and the federal laws of Canada.

Ladies and Gentlemen:

We have acted as Canadian counsel to Canadian Imperial Bank of Commerce (the "<u>Bank</u>") in connection with the issue and sale today (the "<u>Offering</u>") by the Bank of US$700,000,000 6.500% Fixed Rate Reset Limited Recourse Capital Notes Series 9 (Non-Viability Contingent Capital (NVCC)) (Subordinated Indebtedness) (the "<u>Notes</u>") pursuant to an underwriting agreement dated January 6, 2026 (the "<u>Underwriting Agreement</u>") among the Bank and CIBC World Markets Corp., BNP Paribas Securities Corp., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC and UBS Securities LLC, as representatives of the several underwriters named therein (collectively, the "<u>Underwriters</u>"). The Notes are issuable under and pursuant to a subordinated indenture, dated as of November 5, 2024 (the "<u>Base Indenture</u>"), between the Bank and The Bank of New York Mellon, as trustee (the "<u>Trustee</u>"), as amended and supplemented by a supplemental indenture dated as of January 13, 2026 (the "<u>Supplemental Indenture</u>" and together with the Base Indenture, the "<u>Indenture</u>"), among the Bank, the Trustee and Computershare Advantage Trust of Canada, as Canadian co-trustee. We have also acted as Canadian counsel to the Bank in connection with the issuance and sale on January 9, 2026 by the Bank of 700,000 Non-Cumulative 5-Year Fixed Rate Reset Class A Preferred Shares Series 64 (Non-Viability Contingent Capital (NVCC)) of the Bank (the "<u>Preferred Shares</u>" and, collectively with the Notes, the "<u>Securities</u>") to Computershare Trust Company of Canada, as trustee (the "<u>Limited Recourse Trustee</u>") of CIBC LRCN Limited Recourse Trust (the "<u>Limited Recourse Trust</u>").

The Securities are being offered pursuant to a Registration Statement on Form F-3 (File No. 333-282307) (the "<u>Registration Statement</u>"), including the prospectus constituting a part thereof, dated October 2, 2024 (the "<u>Base Shelf Prospectus</u>"), as supplemented by a preliminary prospectus supplement of the Bank dated January 6, 2026 relating to the Securities (the "<u>Preliminary Prospectus Supplement</u>"), as further supplemented by a prospectus supplement of the Bank dated January 6, 2026 relating to the Securities (the "<u>Final Prospectus Supplement</u>" and together with the Base Shelf Prospectus and the Preliminary Prospectus Supplement, the "<u>Prospectus</u>").

In accordance with the terms of an amended and restated declaration of trust dated as of September 14, 2020, as may be supplemented, amended or restated from time to time, in respect of the Limited Recourse Trust made by the Limited Recourse Trustee, the Limited Recourse Trustee will hold the Preferred Shares as registered owner to satisfy the recourse of the holders of the Notes in respect of the Bank's obligations under the Indenture. Upon the occurrence of a Recourse Event (as defined in the Indenture), the limited recourse trust assets held in the Limited Recourse Trust in respect of the Notes, which will initially consist of the Preferred Shares, will be delivered to holders of the Notes.

The provisions attaching to the Preferred Shares (the "<u>Share Terms</u>") provide that the Preferred Shares will convert, upon the occurrence of a Trigger Event (as defined in the Share Terms), into common shares in the capital of the Bank (each, a "<u>Common Share</u>"), subject to certain conditions as described in the Share Terms (an "<u>NVCC Automatic Conversion</u>"). If a Trigger Event occurs and the Preferred Shares are then held in the Limited Recourse Trust, then immediately following such NVCC Automatic Conversion, each holder of the Notes will be entitled to receive such holder's proportionate share of the Preferred Shares then held in the Limited Recourse Trust and subsequently, the Common Shares issued in connection with such Trigger Event (other than any Dividend Common Shares (as defined in the Indenture)) will be delivered to each holder of the Notes, subject to certain conditions as described in the Indenture.

We are qualified to practice law in the Province of Ontario, and we do not express any opinion with respect to the laws of any jurisdiction other than the laws of the Province of Ontario and the federal laws of Canada applicable therein, in each case, in force at the date of this opinion letter.

We, as Canadian counsel to the Bank, have examined originals or copies, certified or otherwise authenticated to our satisfaction, of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. the Prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. the Underwriting Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. the Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. the Share Terms.

In connection with the opinions expressed in this letter we have considered such questions of law and examined such public and corporate records, certificates and other documents and conducted such other examinations as we have considered necessary or appropriate for the purposes of the opinions hereafter expressed, including the following documents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. the by-laws of the Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. officers' certificates of the Bank as to resolutions of the directors of the Bank authorizing the Registration Statement, Prospectus,
the creation and issuance of the Notes and the Preferred Shares and other related matters; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. a Certificate of Confirmation dated January 12, 2026 issued by the Office of the Superintendent of Financial Institutions (Canada)
in respect of the Bank (the " <u>Certificate of Confirmation</u> ").

We understand that the Registration Statement and the Prospectus were filed with the U.S. Securities and Exchange Commission in connection with the Notes and the Preferred Shares.

We have assumed the legal capacity of all individuals, the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as certified, conformed, photostatic, facsimile or electronic copies.

In expressing the opinion in paragraph 1 as to the existence of the Bank, we have relied exclusively on the Certificate of Confirmation, which certificate we assume is accurate as of the date hereof.

The opinion expressed in paragraph 3 is based on the assumption that the Indenture has been duly authorized, executed and delivered by, and is enforceable in accordance with its terms against, the Trustee.

Based upon the foregoing, and subject to the qualifications expressed herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Bank validly exists as a Schedule I bank under the *Bank Act* (Canada) and has the corporate power to create, issue and sell
the Securities, to issue and deliver the Common Shares into which the Preferred Shares may be converted upon an NVCC Automatic Conversion
(as defined in the Share Terms), and to execute, deliver and perform its obligations under the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The creation, issuance, sale and delivery of the Notes have been duly authorized by the Bank and the Notes have been, to the extent
issuance, execution and delivery are matters governed by the laws of the Province of Ontario and the federal laws of Canada applicable
therein, duly issued, executed and delivered by the Bank. The creation, issuance, sale and delivery of the Preferred Shares have been
duly authorized by the Bank and the Preferred Shares have been validly created and allotted and, payment therefor having been made to
the Bank, have been validly issued and are outstanding as fully-paid and non-assessable shares of the Bank. All necessary corporate action
has been taken by the Bank to authorize and reserve for issuance the Common Shares into which the Preferred Shares may be converted upon
an NVCC Automatic Conversion (as defined in the Share Terms) and such Common Shares, when duly issued in accordance with the Share Terms,
will be validly issued, fully-paid and non-assessable shares. The Notes, with respect to the provisions thereof governed by the laws of
the Province of Ontario and the federal laws of Canada applicable therein, constitute a legal, valid and binding obligation of the Bank
enforceable in accordance with their terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Indenture has been duly authorized, executed and, to the extent delivery is a matter governed by the laws of the Province of Ontario
and the federal laws of Canada applicable therein, delivered by the Bank and, with respect to the provisions thereof governed by the laws
of the Province of Ontario and the federal laws of Canada applicable therein, constitutes a legal, valid and binding obligation of the
Bank enforceable in accordance with its terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The execution and delivery by the Bank of, and the performance by the Bank of its obligations under, the Notes and the Indenture,
the issuance and delivery of the Preferred Shares to the Limited Recourse Trustee, and the issuance and delivery of the Common Shares
upon an NVCC Automatic Conversion (as defined in the Share Terms), do not contravene any existing provision of applicable law or result
in a breach (whether after notice or lapse of time or both) of any of the terms, conditions or provisions of the *Bank Act* (Canada)
or the by-laws of the Bank.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Subject to the assumptions, limitations and qualifications set out therein, the statements as to matters of the laws of Canada under
the heading "Material Canadian Federal Income Tax Considerations" in the Final Prospectus Supplement are accurate in all material
respects.

The opinions set forth in paragraphs 2 and 3 above as to the enforceability of the Notes and the Indenture, respectively, are subject to the qualifications that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, preference, moratorium, arrangement or winding-up
laws or other similar laws affecting the enforcement of creditors' rights generally;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. enforceability may be limited by equitable principles, including the principle that equitable remedies such as specific performance
and injunction may only be granted in the discretion of a court of competent jurisdiction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii. enforceability will be subject to the limitations contained in the *Limitations Act, 2002* (Ontario), and we express no opinion
as to whether a court may find any provision of the Notes or the Indenture to be unenforceable as an attempt to vary or exclude a limitation
period under that Act.

Our opinion in paragraph 5 above is limited to the tax matters described herein and does not address any other Canadian federal income tax matters, any other Canadian federal tax matters, any provincial tax matters or any foreign tax matters. Except as noted in the Final Prospectus Supplement, our opinion in paragraph 5 does not take into account or anticipate any changes in law, whether by way of legislative, judicial or governmental decision or action, or in the administrative and assessing practices of the Canada Revenue Agency ("<u>CRA</u>"), and there can be no assurance that the *Income Tax Act* (Canada) or the Income Tax Regulations made thereunder will not be amended, or the CRA administrative and assessing practices changed, in a manner which will affect the considerations that are identified and reviewed in such opinion.

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 letter as an exhibit to a Current Report on Form 6-K to be incorporated by reference in the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the United States Securities Act of 1933.
