(m)

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

(n)

The Bank will not take, directly or indirectly, any action designed to cause or result in, or that might cause or result in, stabilization or manipulation of the price of the Notes to facilitate the sale or resale of the Notes.

COVENANTS of the Underwriters

(a)

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

(b)

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

(c)

CIBC World Markets Corp. further agrees that any offer or sale by its Canadian investment dealer affiliate of the Notes, as contemplated in the paragraph above, purchased by it hereunder in Canada or to any resident of Canada shall only be effected on a private placement basis in accordance with applicable exemptions under the applicable securities laws in the relevant jurisdictions including that CIBC World Markets Corp.’s Canadian investment dealer affiliate (i) will not offer or sell the Notes purchased by it hereunder in Canada except in the Provinces of Ontario, British Columbia, Alberta, Québec and Manitoba (collectively, the Qualifying Provinces) and in each case will only do so in accordance with applicable securities laws in the relevant Qualifying Province; and (ii) with respect to the Qualifying Provinces, represents and agrees that (A) it has not offered, sold, distributed or delivered, and that it will not offer, sell, distribute or deliver, any Notes purchased by it hereunder, directly or indirectly in the Qualifying Provinces or to any person that is resident in any Qualifying Province for the purposes of securities laws applicable therein (including any corporation or other entity organized under the laws of any jurisdiction in Canada), except to persons who are not individuals, who are “permitted clients” as defined under National Instrument 31-103 – Registration Requirements, Exemptions and Ongoing Registrant Obligations and who are “accredited investors” as defined under National Instrument 45-106 – Prospectus Exemptions (NI 45-106) or Section 73.3(1) of the Securities Act (Ontario), as applicable, under the “accredited investor exemption” as defined in NI 45-106; and (B) neither it nor its Canadian investment dealer affiliate will distribute or deliver the Prospectus or Prospectus Supplement or any other offering material relating to the Notes purchased by it hereunder, in the Qualifying Provinces in contravention of the securities laws or regulations of the Qualifying Provinces.

(d)

CIBC World Markets Corp. and its Canadian investment dealer affiliate have taken or will take reasonable 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).

(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.

Indemnity and Contribution

(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.

(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.

(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.

(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.

(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.

(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.

Termination

(a)

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

(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

(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.

(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:

(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);

(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;

(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

(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.

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.

(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.

21.

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.

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.

Redemption:		The Bank may, at its option, with the prior written approval of the Superintendent of Financial Institutions (Canada) (the “Superintendent”) and without the consent of Noteholders, on not less than 10 days’ and not more than 60 days’ prior notice to the registered holders, redeem the Notes, 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, at the Redemption Price. The Bank may, with the prior written approval of the Superintendent and without consent of Noteholders, on not less than 10 days’ and not more than 60 days’ prior written notice to the registered holders, redeem the Notes, in whole but not in part, (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), in each case at the Redemption Price.

		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. 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. Any Notes redeemed by the Bank will be cancelled and will not be reissued. 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.

-3-

		“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.

Limited Recourse:		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.

		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 59 (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.

-4-

		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. 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. 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.

		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.

		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.

		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.

		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.

Purchase for Cancellation:		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. 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. Any Notes so purchased by the Bank will be cancelled and will not be reissued.

NVCC Automatic Conversion:		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.

		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.

-6-

Subordination:		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.

		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.

		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.

Events of Default:		The only events of default with respect to the Notes shall be the bankruptcy, insolvency, liquidation, or winding-up of the Bank.

		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).

		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.

-7-

Risk Factors:		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.

Prohibited Owners:		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).

Use of Proceeds:		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.

No Public Trading Market:		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. 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.

Form and Denomination:		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.

-10-

Dividend Deferability:		If the board of directors does not declare dividends, or any part thereof, on the Preferred Shares on or before the relevant Dividend Payment Date for a particular period, then the rights of the holders of Preferred Shares to receive such dividends, or any part thereof, for the relevant period shall be forever extinguished.

		The Bank may also be restricted under the Bank Act from paying dividends on the Preferred Shares in certain circumstances.

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.

		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.

-11-

	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.

Trigger Event:	A “Trigger Event” has the meaning set out in the CAR Guideline, Chapter 2, Definition of Capital, effective November 2023, as such term may be amended or superseded by OSFI from time to time, which term currently provides that each of the following constitutes a Trigger Event:

	●	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.

-12-

NVCC Automatic Conversion Formula:		The “NVCC Automatic Conversion Formula” is (Multiplier x Share Value) ÷ Conversion Price = number of Common Shares into which each Preferred Share is converted upon a Trigger Event. “Multiplier” means 1.0. “Share Value” of a Preferred Share means US$1,000 together with declared and unpaid dividends as at the date of the Trigger Event, expressed in Canadian dollars. In determining the Share Value of any Preferred Share, the face amount thereof and any declared and unpaid dividends thereon shall be converted from U.S. dollars into Canadian dollars on the basis of the Bank of Canada Closing Rate. “Bank of Canada Closing Rate” means, with respect to a given currency, the closing exchange rate between Canadian dollars and such currency reported by the Bank of Canada on the date immediately preceding the date of the relevant Trigger Event (or if not available on such date, the date on which such closing rate was last available prior to such date), or if such exchange rate is no longer reported by the Bank of Canada, the simple average of the closing exchange rates between Canadian dollars and the relevant currency quoted at approximately 4:00 p.m., New York City time, on such date by three major banks selected by the Bank. “Conversion Price” of each Preferred Share means the greater of (i) the Current Market Price (as defined below) of the Common Shares, and (ii) the Floor Price (as defined below). “Floor Price” means C$2.50, subject to adjustment in the event of (i) the issuance of Common Shares or securities exchangeable for or convertible into Common Shares to all holders of Common Shares as a stock dividend, (ii) the subdivision, redivision or change of the Common Shares into a greater number of Common Shares, or (iii) the reduction, combination or consolidation of the Common Shares into a lesser number of Common Shares. The adjustment shall be computed to the nearest one-tenth of one cent provided that no adjustment of the Floor Price shall be required unless such adjustment would require an increase or decrease of at least 1% of the Floor Price then in effect; provided, however, that in such case any adjustment that would otherwise be required to be made will be carried forward and will be made at the time of and together with the next subsequent adjustment which, together with any adjustments so carried forward, will amount to at least 1% of the Floor Price. “Current Market Price” of the Common Shares means the volume weighted average trading price of the Common Shares on the Toronto Stock Exchange, or, if not then listed on the Toronto Stock Exchange, on the principal securities exchange or market on which the Common Shares are then listed or quoted, for the 10 consecutive trading days ending on the trading day immediately preceding the date of the Trigger Event, converted (if not denominated in Canadian dollars) into Canadian dollars on the basis of the Bank of Canada Closing Rate. If no such trading prices are available, “Current Market Price” shall be the Floor Price.

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.
