the forms of certificates representing the Notes.

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

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

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

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

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

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

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

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

It is understood, however, that, except as provided in this Section 6, Section 8 entitled “Indemnity and Contribution,” and the last paragraph of Section 9 below, the Underwriters will pay all of their own costs and expenses including, transfer taxes payable on resale of any of the Securities by them, any advertising expenses connected with any offers they may make and the fees and disbursements of their counsel.

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

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.

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.

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

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.

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.

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

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.

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.

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

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

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.

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

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)

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.

EFFECTIVENESS; DEFAULTING UNDERWRITERS

ENTIRE AGREEMENT

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.

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:

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);

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;

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

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.

/ US13607H6M92

The Bank is a bank amalgamated under and governed by the Bank Act (Canada) (Bank Act), with all power and authority necessary to conduct the business as described in the Prospectus.

The Bank has the corporate power to execute, deliver and perform its obligations under this Agreement and the Indenture and to sell the Securities to be delivered at the Time of Delivery as contemplated by the Prospectus.

The Bank is a reporting issuer under the Securities Act (Ontario) and is not included on the list of defaulting reporting issuers maintained by the Ontario Securities Commission.

All necessary corporate action has been taken by the Bank to authorize the execution and delivery of this Agreement and the performance of its obligations thereunder and this Agreement has been, to the extent execution and delivery are matters governed by the laws of the Province of Ontario or the federal laws of Canada applicable therein, duly executed and delivered by the Bank.

All necessary corporate action has been taken by the Bank to authorize the creation, issuance, sale and delivery of the Securities to be delivered at the Time of Delivery, and the Securities have been, to the extent issuance, execution and delivery are matters governed by the laws of the Province of Ontario or the federal laws of Canada applicable therein, duly issued, executed and delivered by the Bank.

All necessary corporate action has been taken by the Bank to authorize the execution and delivery of the Indenture and the performance of its obligations thereunder and the Indenture has been, to the extent execution and delivery are matters governed by the laws of the Province of Ontario or the federal laws of Canada applicable therein, duly executed and delivered by the Bank. The Indenture will, with respect to the provisions thereof governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, constitute a legal, valid and binding obligation of the Bank enforceable in accordance with its terms.

The execution and delivery of this Agreement and the Indenture by the Bank, the fulfillment of the terms of this Agreement and the Indenture by the Bank, and the issuance, sale and delivery of the Securities do not and will not result in a breach of or default under, and do not and will not create a state of facts which, after notice or lapse of time or both, will result in a breach of or default under: (a) any of the terms, conditions or provisions of the Bank Act or the by-laws of the Bank or (b) any law, statute, regulation or rule applicable to the Bank or its property or assets;.

The Indenture and the issuance of the Securities thereunder comply, to the extent applicable, with the provisions of the Bank Act. No registration, filing or recording of the Indenture under the laws of the Province of Ontario or the federal laws of Canada applicable therein is necessary or required for the issue of the Securities or the consummation of the transactions contemplated by this Agreement or the Indenture, except such as have been made.

All necessary corporate action has been taken by the Bank to authorize the execution and delivery of the Prospectus and the filing thereof with the Commission.

The statements in the Registration Statement under Part II of the registration statement on Form F-3 under the heading “Indemnification of Directors and Officers”, insofar as such statements constitute statements of the laws of the Province of Ontario or the federal laws of Canada applicable therein or purport to summarize provisions of agreements or instruments, have been reviewed by us and fairly summarize the matters described therein and are accurate in all material respects.

The form of global certificate representing the Securities to be delivered at the Time of Delivery has been approved by the Bank and, to the extent applicable, complies with the provisions of the Bank Act.

The statements in the Prospectus under the heading “Limitations on Enforcement of U.S. Laws Against CIBC, its Management and Others” insofar as such statements constitute statements of Canadian federal law or Ontario law, have been reviewed by us and fairly summarize the matters described therein and are accurate in all material respects.

The statements as to matters of the federal laws of Canada under the heading “Material Canadian Federal Income Tax Considerations” in the Prospectus are an accurate summary, in all material respects, of the principal Canadian federal income tax considerations generally applicable to a purchaser of the Securities described therein, subject to the assumptions, limitations and qualifications set out therein.

All payments by the Bank pursuant to this Agreement shall be made without withholding for taxes under the Income Tax Act (Canada) provided that such payments are not in respect of services rendered in Canada. No goods and services tax or harmonized sales tax imposed under the federal laws of Canada or provincial taxes under the laws of the Province of Ontario will be payable by the Bank to an Underwriter or collectable by an Underwriter in respect of the payment of the commissions as contemplated by this Agreement to an Underwriter that is not a resident of Canada and is not registered under the Excise Tax Act (Canada), provided that any such commissions are in respect of services performed by the Underwriter wholly outside of Canada or the resale of Securities by an Underwriter to persons outside of Canada.

No stamp duty, documentary taxes or similar taxes are payable by the Bank under the federal laws of Canada or the laws of the Province of Ontario in connection with the creation, issuance, sale and delivery of the Securities to an Underwriter or the resale of Securities by an Underwriter to U.S. residents.

A court of competent jurisdiction in Ontario (an Ontario Court) would give a judgment based upon a final and conclusive in personam judgment of a court sitting in the Borough of Manhattan, The City of New York, New York (a New York Court) for a sum certain, obtained against the Bank with respect to a claim arising out of this Agreement, the Indenture or the Securities (a New York Judgment), without reconsideration of the merits provided that:

an action to enforce the New York Judgment must be commenced in the Ontario Court within any applicable limitation period;

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;

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

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

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

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);

the enforcement of the New York Judgment is contrary to or inconsistent with public policy, as such term is interpreted under Ontario Law (Public Policy) or to an order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada) in respect of certain judgments referred to in such statutes; or

the New York Judgment has been satisfied or is void or voidable under the laws of the State of New York (New York Law).

In an action on a final and conclusive judgment in personam of any New York Court that is not impeachable as void or voidable under New York Law, the Ontario Court would give effect to the provisions in this Agreement and the Indenture whereby the Bank has submitted to the non-exclusive jurisdiction of a New York Court, provided that the provisions of this Agreement and the Indenture, as applicable, dealing with service of process on the Bank are duly complied with.

In any proceeding in an Ontario Court for the enforcement of this Agreement, the Indenture or the Securities, the Ontario Court would apply New York Law in accordance with the parties’ choice of law in this Agreement and the Indenture, to all issues which under Ontario Law are to be determined in accordance with the parties’ choice of New York Law in this Agreement and the Indenture (which choice explicitly does not extend to issues in respect of Section 301(b) and Section 1601(a) of the Indenture), provided that:

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;

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

will not take judicial notice of the provisions of New York Law but will only apply such provisions if they are pleaded and proven by expert testimony;

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;

will apply provisions of Ontario Law that have overriding effect;

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

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;

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

an Ontario Court has discretion to decline to hear an action if:

it is contrary to Public Policy;

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

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

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.

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.

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.

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 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.
