**Senior Global Medium-Term Notes**

**$ Fixed to Floating Rate Notes Linked to Compounded SOFR due October 7, 2030**

We, Canadian Imperial Bank of Commerce (the "Bank" or "CIBC"), are offering $ aggregate principal amount of Fixed to Floating Rate Notes Linked to Compounded SOFR (as defined herein, "Compounded SOFR" or the "Reference Rate") due October 7, 2030 (CUSIP 13609FBC7 / ISIN US13609FBC77) (the "Notes").

At maturity, you will receive a cash payment equal to 100% of the principal amount, plus any accrued and unpaid interest. Interest will be paid quarterly on January 7, April 7, July 7 and October 7 of each year, commencing on July 7, 2026 and ending on the Maturity Date. The Notes will accrue interest during the following periods of their term at the following rates per annum:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· From and including the Original Issue Date to but excluding April 7, 2026: 0.00%;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· From and including April 7, 2026 to but excluding the Maturity Date: the sum of Compounded
SOFR on the applicable Interest Determination Date and 1.70%, subject to a Minimum Rate of 0.00% and a Maximum Rate of 5.50%.

The Notes will be issued in minimum denominations of $1,000, and integral multiples of $1,000 in excess thereof.

The Notes will not be listed on any securities exchange.

**The Notes are unsecured obligations of CIBC and all payments on the Notes are subject to the credit risk of CIBC. The Notes will not constitute deposits insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other government agency or instrumentality of Canada, the United States or any other jurisdiction.** 

**Neither the Securities and Exchange Commission (the "SEC") nor any state or provincial securities commission has approved or disapproved of these Notes or determined if this pricing supplement or the accompanying prospectus supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.** 

The Notes are bail-inable debt securities (as defined in the accompanying prospectus) and subject to conversion in whole or in part – by means of a transaction or series of transactions and in one or more steps – into common shares of the Bank or any of its affiliates under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act (the "CDIC Act") and to variation or extinguishment in consequence, and subject to the application of the laws of the Province of Ontario and the federal laws of Canada applicable therein in respect of the operation of the CDIC Act with respect to the Notes. See "Description of Senior Debt Securities ― Special Provisions Related to Bail-inable Debt Securities" and "— Canadian Bank Resolution Powers" in the accompanying prospectus and "Risk Factors ― Risks Relating to Bail-Inable Notes" in the accompanying prospectus supplement.

**Investing in the Notes involves risks not associated with an investment in ordinary debt securities. See the "Additional Risk Factors" beginning on page PS-7 of this pricing supplement and the "Risk Factors" beginning on page S-1 of the accompanying prospectus supplement and page 1 of the prospectus.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Because certain dealers who purchase the Notes for sale to certain fee-based advisory
accounts may forgo some or all of their commissions or selling concessions, the price to public for investors purchasing the Notes in
these accounts may be between $990.00 and $1,000.00 per Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) CIBC World Markets Corp. ("CIBCWM"), acting as agent for the Bank, will
receive a commission of up to $10.00 (1.00%) per $1,000 principal amount of the Notes. CIBCWM may use a portion or all of its commission
to allow selling concessions to other dealers in connection with the distribution of the Notes. The other dealers may forgo, in their
sole discretion, some or all of their selling concessions. See "Supplemental Plan of Distribution (Conflicts of Interest)"
on page PS-15 of this pricing supplement.

We will deliver the Notes in book-entry form through the facilities of The Depository Trust Company ("DTC") on or about October 7, 2025 against payment in immediately available funds.

**ADDITIONAL RISK FACTORS**

An investment in the Notes involves significant risks. In addition to the following risks included in this pricing supplement, we urge you to read "Risk Factors" beginning on page S-1 of the accompanying prospectus supplement and page 1 of the accompanying prospectus.

You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisers, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus and prospectus supplement.

***Structure Risks***

 ****

**The Interest Rate for Each Interest Period During the Floating Rate Payment Period is Variable and May Be as Low as the Minimum Rate.**

You will receive interest on the applicable Interest Payment Date during the Floating Rate Payment Period at the Interest Rate calculated on the corresponding Interest Determination Date, which may be as low as the Minimum Rate. The Interest Rate applicable to each Interest Payment Date during the Floating Rate Payment Period will fluctuate because it is equal to the sum of Compounded SOFR calculated on the applicable Interest Determination Date and 1.70%, subject to the Minimum Rate and the Maximum Rate. If Compounded SOFR calculated on any Interest Determination Date were less than -1.70%, the Interest Rate for the relevant Interest Period would be equal to the Minimum Rate. Compounded SOFR, on which the Interest Rate for each Interest Period during the Floating Rate Payment Period is based, will vary and may be less than -1.70% for most or all of the Interest Determination Dates, and you may receive interest at the Minimum Rate on most or all of the Interest Payment Dates during the Floating Rate Payment Period. The return on the Notes may be lower than the return on conventional debt securities of comparable maturity. As a result, your investment in the Notes may not reflect the full opportunity cost to you when you consider factors that affect the time value of money.

**The Potential Return on the Notes Will Be Limited by the Maximum Rate.**

The Interest Rate applicable for each Interest Period will not be greater than the Maximum Rate. Therefore, your return on the Notes will be limited by the Maximum Rate.

**You Will Not Know the Interest Rate for Each Interest Period During the Floating Rate Payment Period Until the End of that Interest Period.**

The Reference Rate is compounded in arrears. Unlike forward-looking term rates, the Interest Rate for each Interest Period during the Floating Rate Payment Period will be calculated at the end of that Interest Period.

**The Repayment of the Principal Amount Applies Only at Maturity.**

The Notes offer repayment of the principal amount only if you hold your Notes until the Maturity Date. If you sell the Notes prior to maturity, you may lose some of the principal amount.

**The** **Notes Will Be Subject to Risks, Including Conversion in Whole or in Part — by Means of a Transaction or Series of Transactions and in One or More Steps — into Common Shares of CIBC or Any of its Affiliates, Under Canadian Bank Resolution Powers.**

Under Canadian bank resolution powers, the Canada Deposit Insurance Corporation (the "CDIC") may, in circumstances where CIBC has ceased, or is about to cease, to be viable, assume temporary control or ownership of CIBC and may be granted broad powers by one or more orders of the Governor in Council (Canada), including the power to sell or dispose of all or a part of the assets of CIBC, and the power to carry out or cause CIBC to carry out a transaction or a series of transactions the purpose of which is to restructure the business of CIBC. If the CDIC were to take action under the Canadian bank resolution powers with respect to CIBC, this could result in holders or beneficial owners of the Notes being exposed to losses and conversion of the Notes in whole or in part — by means of a transaction or series of transactions and in one or more steps — into common shares of CIBC or any of its affiliates.

As a result, you should consider the risk that you may lose all or part of your investment, including the principal amount plus any accrued interest, if the CDIC were to take action under the Canadian bank resolution powers, including the bail-in regime, and that any remaining outstanding Notes, or common shares of CIBC or any of its affiliates into which the Notes are converted, may be of little value at the time of a bail-in conversion and thereafter. See "Description of Senior Debt Securities―Special Provisions Related to Bail-inable Debt Securities" and "—

Canadian Bank Resolution Powers" in the accompanying prospectus and "Risk Factors — Risks Relating to Bail-Inable Notes" in the accompanying prospectus supplement for a description of provisions and risks applicable to the Notes as a result of Canadian bail-in powers.

**The Notes Are Riskier Than Notes With a Shorter Term.**

The Notes are relatively long-dated. Therefore, many of the risks of the Notes are heightened as compared to notes with a shorter term, as you will be subject to those risks for a longer period of time. In addition, the value of a longer-dated note is typically less than the value of an otherwise comparable note with a shorter term.

***Reference Rate Risks***

 ****

**The Occurrence of a Benchmark Transition Event Could Adversely Affect the Return (if any) on the Notes.**

A Benchmark Transition Event (as defined in "Description of the Notes We May Offer – Interest Rates – Floating Rate Notes – SOFR Notes – Effect of a Benchmark Transition Event for Compounded SOFR Notes" in the accompanying prospectus supplement) could occur during the term of the Notes. Any resulting alternative replacement and Calculation Agent adjustments and determinations, as described in "Description of the Notes We May Offer – Interest Rates – Floating Rate Notes – SOFR Notes – Effect of a Benchmark Transition Event for Compounded SOFR Notes" in the accompanying prospectus supplement, could adversely affect the value of and the return on your Notes.

**The Secured Overnight Financing Rate ("SOFR") May Be Modified or Discontinued.**

The Federal Reserve Bank of New York notes on its publication page for SOFR that use of SOFR is subject to important limitations, indemnification obligations and disclaimers, including that the Federal Reserve Bank of New York may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice. There can be no guarantee that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which SOFR is calculated is changed or if SOFR is discontinued, that change, or discontinuance may result in a reduction of the interest or other applicable payments payable on the Notes and a reduction in the trading price of the Notes.

**The Future Performance of SOFR Cannot Be Predicted Based on Historical Performance.**

The future performance of SOFR cannot be predicted based on its historical performance. Prior observed patterns, if any, in the behavior of market variables and their relation to SOFR, such as correlations, may change in the future. While some pre-publication historical data have been released by the Federal Reserve Bank of New York, such analysis inherently involves assumptions, estimates and approximations. The future performance of SOFR is impossible to predict and therefore no future performance of SOFR may be inferred from any of the historical actual or historical indicative data. Hypothetical or historical performance data are not indicative of, and have no bearing on, the potential performance of SOFR. You should not rely on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates.

**Any Failure of SOFR to Retain or Increase Market Acceptance Could Adversely Affect the Notes.**

SOFR is based on transactions secured by U.S. Treasury securities; it does not measure bank-specific credit risk. As a result, SOFR is less likely to correlate with the unsecured short-term funding costs of banks. Any failure of SOFR to retain or increase its market acceptance could adversely affect the return on and value of the Notes and the price at which investors can sell the Notes in the secondary market.

***Conflicts of Interest***

 ****

**Certain Business, Trading and Hedging Activities of Us, CIBCWM and Our Other Affiliates May Create Conflicts with Your Interests and Could Potentially Adversely Affect the Value of the Notes** **.**

We, CIBCWM or one or more of our other affiliates may engage in trading and other business activities that are not for your account or on your behalf (such as holding or selling of the Notes for our proprietary account or effecting secondary market transactions in the Notes for other customers). These activities may present a conflict of interest between your interest in the Notes and the interests we, CIBCWM or one or more of our other affiliates may have in our or their proprietary accounts. We, CIBCWM and our other affiliates may engage in any such activities without regard to the Notes or the effect that such activities may directly or indirectly have on the value of the Notes.

Moreover, we, CIBCWM and our other affiliates play a variety of roles in connection with the issuance of the Notes, including hedging our obligations under the Notes. We expect to hedge our obligations under the Notes through CIBCWM, one of our other affiliates and/or another unaffiliated counterparty, which may include any dealer from

which you purchase the Notes. In connection with such activities, the economic interests of us, CIBCWM and our other affiliates may be adverse to your interests as an investor in the Notes. Any of these activities may adversely affect the value of the Notes. In addition, because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging activity may result in a profit that is more or less than expected, or it may result in a loss. We, CIBCWM, one or more of our other affiliates or any unaffiliated counterparty will retain any profits realized in hedging our obligations under the Notes even if investors do not receive a favorable investment return under the terms of the Notes or in any secondary market transaction. Any profit in connection with such hedging activities will be in addition to any other compensation that we, CIBCWM, our other affiliates or any unaffiliated counterparty receive for the sale of the Notes, which creates an additional incentive to sell the Notes to you. We, CIBCWM, our other affiliates or any unaffiliated counterparty will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the Notes.

**There Are Potential Conflicts of Interest Between You and the Calculation Agent.**

The Calculation Agent will, among other things, determine the Interest Rate and decide the amount of your payment for any Interest Payment Date on the Notes. The Calculation Agent will exercise its judgment when performing its functions. Because determinations made by the Calculation Agent may affect payments on the Notes, the Calculation Agent may have a conflict of interest if it needs to make any such determination.

In addition, and without limiting the generality of the previous paragraph, the Calculation Agent may make certain determinations if a Benchmark Transition Event occurs or it may administer a successor rate in certain circumstances as also described herein. For the avoidance of doubt, any decision made by the Calculation Agent will be effective without consent from the holders of the Notes or any other party. Potential conflicts of interest may exist between the Bank, the Calculation Agent and holders of the Notes. All determinations made by the Calculation Agent in such a circumstance will be conclusive for all purposes and binding on the Bank and holders of the Notes. In making these potentially subjective determinations, the Bank and/or the Calculation Agent may have economic interests that are adverse to your interests, and such determinations may adversely affect the value of and return on your Notes. Because the continuation of SOFR on the current basis cannot and will not be guaranteed, the Calculation Agent is likely to exercise more discretion in respect of calculating interest payable on the Notes than would be the case in the absence of such a need to select a successor rate.

***Tax Risks***

 ****

**The Tax Treatment of the Notes Is Uncertain.**

Significant aspects of the tax treatment of the Notes are uncertain. You should consult your tax advisor about your own tax situation. See "U.S. Federal Income Tax Considerations" and "Certain Canadian Income Tax Considerations" in this pricing supplement.

***General Risks***

 ****

**Payments on the Notes Are Subject to Our Credit Risk, and Actual or Perceived Changes in Our Creditworthiness Are Expected to Affect the Value of the Notes.**

The Notes are our senior unsecured debt obligations and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus and prospectus supplement, the Notes will rank on par with all of our other unsecured and unsubordinated debt obligations, except such obligations as may be preferred by operation of law. All payments to be made on the Notes, including the interest payments and the return of the principal amount at maturity, depend on our ability to satisfy our obligations as they come due. As a result, the actual and perceived creditworthiness of us may affect the market value of the Notes and, in the event we were to default on our obligations, you may not receive the amounts owed to you under the terms of the Notes. If we default on our obligations under the Notes, your investment would be at risk and you could lose some or all of your investment. See "Description of Senior Debt Securities—Events of Default" in the accompanying prospectus.

**The Inclusion of Dealer Spread and Projected Profit from Hedging in the Original Issue Price Is Likely to Adversely Affect Secondary Market Prices.**

Assuming no change in market conditions or any other relevant factors, the price, if any, at which CIBCWM or any other party is willing to purchase the Notes at any time in secondary market transactions will likely be significantly lower than the original issue price, since secondary market prices are likely to exclude underwriting commissions paid with respect to the Notes and the cost of hedging our obligations under the Notes that are included in the original issue price. The cost of hedging includes the projected profit that we and/or our affiliates may realize in

consideration for assuming the risks inherent in managing the hedging transactions. These secondary market prices are also likely to be reduced by the costs of unwinding the related hedging transactions. In addition, any secondary market prices may differ from values determined by pricing models used by CIBCWM as a result of dealer discounts, mark-ups or other transaction costs.

**The Notes Will Not Be Listed on Any Securities Exchange and We Do Not Expect a Trading Market for the Notes to Develop.**

The Notes will not be listed on any securities exchange. Although CIBCWM and/or its affiliates may purchase the Notes from holders, they are not obligated to do so and are not required to make a market for the Notes. There can be no assurance that a secondary market will develop for the Notes. Because we do not expect that any market makers will participate in a secondary market for the Notes, the price at which you may be able to sell your Notes is likely to depend on the price, if any, at which CIBCWM and/or its affiliates are willing to buy your Notes.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your Notes prior to maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the Notes to maturity.

**U.S. FEDERAL INCOME TAX CONSIDERATIONS**

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the Notes. The following summary is not complete and is both qualified and supplemented by (although to the extent inconsistent supersedes) the discussion entitled "Material Income Tax Consequences—United States Taxation" in the accompanying prospectus, which you should carefully review prior to investing in the Notes. It applies only to those U.S. Holders who are not excluded from the discussion of United States Taxation in the accompanying prospectus.

**You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the Notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.**

In the opinion of Mayer Brown LLP, the Notes should be treated as debt instruments for U.S. federal income tax purposes. Assuming such treatment is respected, the coupon on a Note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder's normal method of accounting for tax purposes. Please see the discussion in the prospectus under the section entitled "Material Income Tax Consequences—United States Taxation—Variable Interest Rate Securities" for a discussion of the OID consequences applicable to the Notes. Under these rules, the Notes may be issued with OID. Whether the Notes will be treated as being issued with OID will depend on rates in effect on the issue date and, in that event, the final pricing supplement will so specify.

Upon the sale, exchange, retirement or other disposition of a Note, a U.S. Holder will recognize taxable gain or loss equal to the difference, if any, between the amount realized on the sale, exchange, retirement or other disposition, other than accrued but unpaid interest which will be taxable as interest, and such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's adjusted tax basis in a Note generally will equal the cost of the Note to such U.S. Holder, increased by any OID previously included in income with respect to the Note, and decreased by the amount of any payment (other than a payment of qualified stated interest) received in respect of the Note. Any gain or loss on the sale, exchange, retirement or other disposition of a Note will generally be capital gain or loss. For a non-corporate U.S. Holder, under current law, the maximum marginal U.S. federal income tax rate applicable to the gain will be generally lower than the maximum marginal U.S. federal income tax rate applicable to ordinary income if the U.S. Holder's holding period for the Notes exceeds one year (i.e., such gain is long-term capital gain). Any gain or loss realized on the sale, exchange, retirement or other disposition of a Note generally will be treated as U.S. source gain or loss, as the case may be. Consequently, a U.S. Holder may not be able to claim a credit for any non-U.S. tax imposed upon a disposition of a Note. The deductibility of capital losses is subject to limitations.

**CERTAIN CANADIAN INCOME TAX CONSIDERATIONS**

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the *Income Tax Act (Canada)* and the regulations thereto (the "Canadian Tax Act") generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a Note pursuant to this pricing supplement and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm's length with the Issuer and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the Note; (c) acquires and holds Notes and any common shares acquired on a bail-in conversion as capital property; (d) does not use or hold and is not deemed to use or hold the Note or any common shares acquired on a bail-in conversion in, or in the course of, carrying on a business in Canada; (e) is entitled to receive all payments (including any interest and principal) made on the Note; (f) is not a, and deals at arm's length with any, "specified shareholder" of the Issuer for purposes of the thin capitalization rules in the Canadian Tax Act; and (g) is not an entity in respect of which the Issuer or any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of, loans or otherwise transfers the Note is a "specified entity", and is not a "specified entity" in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Rules, as defined below (a "Non-Resident Holder"). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a "hybrid mismatch arrangement" under which the payment arises within the meaning of the rules in the Canadian Tax Act with respect to "hybrid mismatch arrangements" (the "Hybrid Mismatch Rules"). Investors should note that the Hybrid Mismatch Rules are highly complex and there remains significant uncertainty as to their interpretation and application.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning Notes under "Material Income Tax Consequences—Canadian Taxation" in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

For the purposes of the Canadian Tax Act, all amounts not otherwise expressed in Canadian dollars must be converted into Canadian dollars based on the exchange rate as quoted by the Bank of Canada for the applicable day or such other rate of exchange acceptable to the Minister of National Revenue (Canada).

**This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.**

**Notes**

Interest payable on the Notes should not be considered to be "participating debt interest" as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by the Issuer on a Note as, on account of or in lieu of payment of, or in satisfaction of, interest.

In the event that a Note held by a Non-Resident Holder is converted to common shares on a bail-in conversion, the amount (the "Excess Amount"), if any, by which the fair market value of the common shares received on the conversion exceeds the sum of: (i) the price for which the Note was issued, and (ii) any amount that is paid in respect of accrued and unpaid interest at the time of the conversion (the "Conversion Interest") may be deemed to be interest paid to the Non-Resident Holder. There is a risk that the Excess Amount (if any) and the Conversion Interest could be characterized as "participating debt interest" and, therefore, subject to Canadian non-resident withholding tax unless certain exceptions apply.

Non-Resident Holders should consult their own advisors regarding the consequences to them of a disposition of the Notes to a person with whom they are not dealing at arm's length for purposes of the Canadian Tax Act.

**Common Shares Acquired on a Bail-in Conversion**

*Dividends*

Dividends paid or credited or deemed to be paid or credited to a Non-Resident Holder on common shares of the Issuer or of any affiliate of the Issuer that is a corporation resident or deemed to be resident in Canada will be subject to Canadian non-resident withholding tax of 25% but such rate may be reduced under the terms of an applicable income tax treaty.

*Dispositions*

A Non-Resident Holder will not be subject to tax under the Canadian Tax Act on any capital gain realized on a disposition or deemed disposition of any common shares of the Issuer or of any affiliate unless the common shares constitute "taxable Canadian property" to the Non-Resident Holder for purposes of the Canadian Tax Act at the time of their disposition, and such Non-Resident Holder is not entitled to relief pursuant to the provisions of an applicable income tax treaty.

Generally, the common shares of the Issuer or of any such affiliate will not constitute taxable Canadian property to a Non-Resident Holder provided that they are listed on a designated stock exchange (which includes the TSX and NYSE) at the time of the disposition, unless, at any particular time during the 60-month period that ends at that time, the following conditions are met concurrently: (i) one or any combination of (a) the Non-Resident Holder, (b) persons with whom the Non-Resident Holder did not deal at arm's length, or (c) partnerships in which the Non-Resident Holder or a person described in (b) holds a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any class or series of the applicable issuer's share capital and (ii) more than 50% of the fair market value of the common shares of such issuer was derived directly or indirectly from one or any combination of (a) real or immovable property situated in Canada, (b) Canadian resource properties (as defined in the Canadian Tax Act), (c) timber resource properties (as defined in the Canadian Tax Act), and (d) an option, an interest or right in any of the foregoing property, whether or not such property exists. Notwithstanding the foregoing, a common share of the Issuer or of any such affiliate may be deemed to be "taxable Canadian property" in certain other circumstances. Non-Resident Holders whose common shares of the Issuer or of any such affiliate may constitute taxable Canadian property should consult their own tax advisers with respect to their particular circumstances.

**SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)**

CIBCWM will purchase the Notes from CIBC at the price to public less the underwriting discount set forth on the cover page of this pricing supplement for distribution to other registered broker-dealers or will offer the Notes directly to investors.

CIBCWM or other registered broker-dealers will offer the Notes at the price to public set forth on the cover page of this pricing supplement. CIBCWM may receive a commission of up to $10.00 (1.00%) per $1,000 principal amount of the Notes and may use a portion or all of that commission to allow selling concessions to other dealers in connection with the distribution of the Notes. The other dealers may forgo, in their sole discretion, some or all of their selling concessions. The price to public for Notes purchased by certain fee-based advisory accounts may vary between 99.00% and 100.00% of the principal amount of the Notes. Any sale of a Note to a fee-based advisory account at a price to public below 100.00% of the principal amount will reduce the agent's commission specified on the cover page of this pricing supplement with respect to such Note. The price to public paid by any fee-based advisory account will be reduced by the amount of any fees assessed by the dealers involved in the sale of the Notes to such advisory account but not by more than 1.00% of the principal amount of the Notes.

CIBCWM is our affiliate, and is deemed to have a conflict of interest under FINRA Rule 5121. In accordance with FINRA Rule 5121, CIBCWM may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer.

We expect to deliver the Notes against payment therefor in New York, New York, on a date that is more than one business day following the Trade Date. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement.

We may use this pricing supplement in the initial sale of the Notes. In addition, CIBCWM or any of our other affiliates may use this pricing supplement in market-making transactions in any Notes after their initial sale. Unless CIBCWM or we inform you otherwise in the confirmation of sale, this pricing supplement is being used by CIBCWM in a market-making transaction.

While CIBCWM may make markets in the Notes, it is under no obligation to do so and may discontinue any market-making activities at any time without notice. See the section titled "Supplemental Plan of Distribution (Conflicts of Interest)" in the accompanying prospectus supplement.

The price at which you purchase the Notes includes costs that the Bank or its affiliates expect to incur and profits that the Bank or its affiliates expect to realize in connection with hedging activities related to the Notes. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the Notes. As a result, you may experience an immediate and substantial decline in the market value of your Notes on the Original Issue Date.
