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

Covenants of the Bank

The Bank covenants with each Underwriter as follows:

(a)

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

(b)

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

(c)

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

(d)

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

(e)

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

(f)

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

(g)

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

(h)

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

(k)

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

(l)

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

(m)

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

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 Securities to the Canadian investment dealer affiliate of CIBC World Markets Corp. Each Underwriter further agrees that it will include a comparable provision in any sub-underwriting, banking group or selling group agreement or similar arrangement with respect to the Securities that may be entered into by such Underwriter.

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

(c)

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

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, 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, 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 Securities as set forth in the Prospectus. The relative fault of the Bank on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Bank or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Securities they have purchased hereunder, and not joint.

(e)

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

(f)

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

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 Securities for any reason permitted under this Agreement, the Bank will reimburse the Underwriters for all reasonable out-of-pocket disbursements (including fees and expenses of counsel to the Underwriters) incurred by the Underwriters in connection with any investigation or preparation made by them in respect of the marketing of the Securities or in contemplation of the performance by them of their obligations hereunder.

10.

Effectiveness; Defaulting Underwriters

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

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

11.

Entire Agreement

(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 Securities, and such relationship between the Bank, on the one hand, and the Underwriters, on the other hand, is entirely and solely a commercial relationship, based on arms-length negotiations;

(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.

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” in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus and the statements in the tenth and eleventh paragraphs under the caption “Underwriting” 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.

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.

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.

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 XXXXX on the SEC website at xxx.xxx.xxx. 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 (000) 000-0000; BofA Securities, Inc. toll-free at (000) 000-0000; X.X. Xxxxxx Securities LLC collect at (000) 000-0000; Xxxxxx Xxxxxxx & Co. LLC toll-free at (000) 000-0000 and UBS Securities LLC toll-free at (000) 000-0000.

**We expect that delivery of the Notes will be made against payment therefor on or about April 28, 2023, which is four business days following the date of pricing of the Notes (this settlement cycle being referred to as “T+4”). Under Rule 15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their Notes on any date prior to two business days before delivery will be required, by virtue of the fact that the Notes initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade their Notes on any date prior to two business days before delivery should consult their own advisor.

(b)

the Ontario Court has discretion to stay or decline to hear an action on the New York Judgment if such New York Judgment is under appeal or there is another subsisting judgment in any jurisdiction relating to the same cause of action as the New York Judgment;

EXHIBIT A1-2

	(c)	the Ontario Court will render judgment only in Canadian dollars; and

(d)

an action in the Ontario Court on the New York Judgment may be affected by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors’ rights generally; and

further, the Ontario Court will not give such judgment if:

	(i)	the New York Judgment was obtained by fraud or in a manner contrary to the principles of natural justice;

	(ii)	the New York Judgment is for a claim which would be characterized as based directly or indirectly on foreign revenue, expropriatory, penal, or other public law under the laws of the Province of Ontario and the federal laws applicable in the Province of Ontario (Ontario Law);

	(a)	the parties’ choice of New York Law is bona fide and legal and is not contrary to Public Policy, as that term is understood under Ontario Law;

	(b)	in any such proceeding, and notwithstanding the parties’ choice of New York Law, the Ontario Court:

(i)

	(ii)	will apply Ontario Law to matters that would be characterized as procedural under Ontario Law and will not apply New York Law that would be characterized as procedural under Ontario Law;

	(iii)	will apply provisions of Ontario Law that have overriding effect;

	(iv)	will not apply any New York Law if its application would be contrary to Public Policy, as that term is understood under Ontario Law;

	(v)	will not apply New York Law if such application would be characterized under Ontario Law as the direct or indirect enforcement of a foreign revenue, expropriatory, penal or other public law;

	(vi)	will not enforce the performance of any obligation that is illegal under the laws of any jurisdiction in which the obligation is to be performed; and

	(c)	an Ontario Court has discretion to decline to hear an action if:

	(i)	it is contrary to Public Policy;

	(ii)	it is not the proper forum to hear such an action; or

(iii)

another action is properly pending before, or a decision has been rendered by, a foreign authority relating to the same cause of action.

and we have no reason to believe that the parties’ choice of law in this Agreement and the Indenture would be contrary to Public Policy, as that term is understood under Ontario Law.

Form of Opinion of Xxxxx Xxxxx LLP

(To be delivered pursuant to Section 5(f) of the Underwriting Agreement)

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

2.	The Indenture has been duly qualified under the Trust Indenture Act.

Assuming the Securities have been duly authorized, established, executed and delivered by CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein and are valid and legally binding obligations of CIBC under the laws of the Province of Ontario and the federal laws of Canada applicable therein, when executed and authenticated by the Trustee in accordance with the terms and provisions of the Indenture and delivered against due payment therefor as provided in the Underwriting Agreement, the Securities will constitute valid, binding and enforceable obligations of CIBC, entitled to the benefits of the Indenture (subject, as to enforceability, to applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally from time to time in effect and to general principles of equity regardless of whether enforceability is considered in a proceeding in equity or at law); provided that such counsel need not express any opinion with respect to Section 301(b) of the Base Indenture, Section 1601(a) of the Base Indenture (as set forth in Section 2.7 of the First Supplemental Indenture), and the corresponding provisions of the Securities, each of which is governed by the laws of the Province of Ontario and the federal laws of Canada.

The execution and delivery by the Bank of, and the performance by the Bank of its obligations under, this Agreement, the Indenture and the Securities will not contravene any provision of any United States federal or New York State law, rule or regulation, in each case which, in such counsel’s opinion, based on such counsel’s experience, are normally applicable to transactions of the type contemplated by this Agreement, the Indenture or the Securities (United States Applicable Laws), except that such counsel need not express any opinion in this paragraph with respect to state securities laws.

EXHIBIT A2-1

The Registration Statement, or any amendment thereto, as of its most recent effective date with respect to the Underwriters, and the Prospectus, or any supplement or amendment thereto, as of its date, in each case, other than the financial statements and notes thereto and the other financial data contained therein, as to which such counsel need express no opinion, and excluding the documents incorporated by reference therein, each appeared on its face to comply as to form in all material respects with the applicable requirements of the Securities Act and the rules and regulations thereunder and the Trust Indenture Act and the rules and regulations thereunder, and the Form F-X, as of its date, appeared on its face to comply as to form in all material respects with the applicable requirements of the Securities Act and the rules and regulations thereunder applicable to such form.

Based upon such counsel’s review of United States Applicable Laws, no consent, approval, authorization or order of, or qualification with, any United States federal or New York state governmental body or agency is required for the performance by the Bank of its obligations under this Agreement, the Indenture or the Securities, except for the registration of the Securities under the Securities Act, the qualification of the Indenture under the Trust Indenture Act and such as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Securities.

7.	The statements set forth in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities,” insofar as such statements purport to summarize certain provisions of the Securities or the Indenture, fairly summarize the matters set forth therein in all material respects.

The discussion of tax matters set forth in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus under the caption “Material Income Tax Consequences – United States Taxation,” insofar as such statements constitute a summary of the United States federal tax laws referred to therein as of such date and as of the date of such opinion, are accurate and fairly summarize in all material respects the United States federal tax laws referred to therein (subject to the qualifications and assumptions set forth in such discussion).

The Bank is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Time of Sale Prospectus and the Prospectus will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

EXHIBIT A2-2

10.

Assuming this Agreement and the Indenture have been duly authorized, executed and delivered by the Bank under the laws of the Province of Ontario or the federal laws of Canada applicable therein and assuming the validity of such actions under the laws of the Province of Ontario or the federal laws of Canada applicable therein, under the laws of the State of New York relating to submission to jurisdiction, the Bank has, pursuant to Section 20 of this Agreement and Section 1501 of the Indenture, (i) validly submitted to the non-exclusive jurisdiction of the U.S. federal and New York State courts sitting in The City of New York in connection with any action or proceeding arising out of or related to this Agreement, the Indenture or the Securities or the transactions contemplated thereby and (ii) validly appointed an authorized agent for service of process pursuant to Section 20 of this Agreement and Section 1501 of the Indenture.

Such counsel shall also state that (i) the staff of the Commission has confirmed that the Registration Statement was declared effective by the Commission on September 28, 2021; (ii) any required filings of the Preliminary Prospectus or the Prospectus pursuant to Rule 424(b) have been made in the manner and within the time period required by such rule; (iii) that, based solely on conversations with the Commission, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for the purpose have been instituted, are pending or, to such counsel’s knowledge, are contemplated under the Securities Act; and (iv) that, based solely on inquiries of the Bank, the Bank is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the Securities Act and the Bank is not the subject of a pending proceeding under Section 8A of the Securities Act in connection with the offering of the Securities.

In addition, such counsel shall also state that they have examined various documents and participated in discussions with representatives of the Bank and its accountants and with representatives of the Underwriters and their counsel at which the contents of the Registration Statement, the Time of Sale Prospectus and the Prospectus and related matters were discussed. However, except as specifically noted in paragraphs (7) and (8) above, such counsel is not passing upon and assumes no responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus or the Prospectus or making any representation that such counsel has independently verified or checked the accuracy, completeness or fairness of such statements or assessments of or reports on the effectiveness of internal control over financial reporting contained in, incorporated by reference into or omitted from the Registration Statement, the Time of Sale Prospectus or the Prospectus. Subject to the foregoing, such counsel shall advise that nothing has come to its attention that caused it to believe that (i) the Registration Statement, or any amendment thereto, as of its most recent effective date with respect to the Underwriters, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) the Time of Sale Prospectus, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) the Prospectus or any supplement or amendment thereto, as of its date or at the date of such opinion, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except for the Form T-1 and the financial statements, supporting schedules and other financial or statistical data included or incorporated by reference therein or omitted therefrom as to which such counsel need express no belief).

In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of the Province of Ontario or the federal laws of Canada applicable therein to the extent they deem proper upon the opinion of Xxxxx, Xxxxxxx & Xxxxxxx LLP referred to in Section 6(e) of this Agreement, and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Bank and public officials and on the representations of the Bank as provided in this Agreement.
