DESCRIPTION OF SENIOR DEBT SECURITIES

The following describes the material terms of the senior debt securities. The senior debt securities will be issued under the indenture (the “Base Indenture”), dated as of September 15, 2012 between CIBC and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as supplemented by the first supplemental indenture thereto dated as of November 6, 2018 and the second supplemental indenture thereto dated as of December 16, 2019 (together with the Base Indenture, and as may be further amended or supplemented from time to time, the “indenture”), copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part. The specific terms applicable to a particular issuance of senior debt securities and any variations from the terms set forth below will be set forth in the applicable prospectus supplement. In this section, “CIBC,” “we,” “us” or “our” means Canadian Imperial Bank of Commerce, the issuer of the senior debt securities, and not its subsidiaries.

The following is a summary of the material terms and provisions of the indenture and the senior debt securities. You should refer to the indenture and the senior debt securities for complete information regarding the terms and provisions of the indenture and the senior debt securities. The indenture is subject to and governed by the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and applicable Canadian trust indenture legislation.

Ranking

The senior debt securities will not be secured by any of our property or assets or the property or assets of our subsidiaries. Thus, by owning a senior debt security, you are one of our unsecured creditors.

The senior debt securities will be unsubordinated obligations that rank equally with all of our other unsecured and unsubordinated debt, including deposit liabilities, other than certain governmental claims in accordance with applicable law.

In the event we become insolvent, our governing legislation provides that priorities among payments of our deposit liabilities (including payments in respect of the senior debt securities) and payments of all of our other liabilities are to be determined in accordance with the laws governing priorities and, where applicable, by the terms of the indebtedness and liabilities. In addition, our right to participate in any distribution of the assets of our banking or non-banking subsidiaries, upon a subsidiary’s dissolution, winding-up, liquidation or reorganization or otherwise, and thus your ability to benefit indirectly from such distribution, is subject to the prior claims of creditors of that subsidiary, except to the extent that we may be a creditor of that subsidiary and our claims are recognized. There are legal limitations on the extent to which some of our subsidiaries may extend credit, pay dividends or otherwise supply funds to, or engage in transactions with, us or some of our other subsidiaries. Accordingly, the senior debt securities will be structurally subordinated to all existing and future liabilities of our subsidiaries, and holders of senior debt securities should look only to our assets for payments on the senior debt securities.

The senior debt securities will not constitute deposits insured under the CDIC Act or by the United States Federal Deposit Insurance Corporation or any other Canadian or U.S. governmental agency or instrumentality.

General

We may issue as many distinct series of senior debt securities under the indenture as we wish. The provisions of the indenture allow us not only to issue senior debt securities with terms different from those previously issued under the applicable indenture, but also to “re-open” a previous issue of a series of senior debt securities and issue additional senior debt securities of that series. We do not intend to re-open a previous issue of a series of debt securities where such re-opening would have the effect of making the relevant debt securities of such series subject to bail-in conversion (as defined below under “ — Special Provisions Related to Bail-inable Debt Securities”). We may issue senior debt securities in amounts that exceed the total amount specified on the cover of your applicable prospectus supplement at any time without your consent and without notifying you. In addition, we may issue additional senior debt securities of any series at any time without your consent and without notifying you. We may also issue other securities at any time without your consent and without notifying you. The indenture does not limit our ability to incur other indebtedness or to issue other securities, and we are not subject to financial or similar restrictions under the indenture.

This section summarizes the material terms of the senior debt securities that are common to all series, subject to any modifications contained in an applicable prospectus supplement. Most of the specific terms of your series will be described in the applicable prospectus supplements accompanying this prospectus. The specific terms of your senior debt security as described in the applicable prospectus supplements will supplement and, if applicable, may modify or replace the general terms described in this section. If there are any differences between the information in the applicable prospectus supplements and this prospectus, the information in the most recent applicable prospectus supplement will control. Accordingly, the statements we make in this section may not apply to your senior debt securities. Because this section is a summary, it does not describe every aspect of the senior debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture and the applicable series of senior debt securities, including definitions of certain terms used in the indenture and the applicable series of senior debt securities. In this summary, we describe the meaning of only some of the more important terms. You must look to the indenture or the applicable series of senior debt securities for the most complete description of what we describe in summary form in this prospectus.

We may issue the senior debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their stated principal amount. An applicable prospectus supplement relating to the original issue discount securities will describe U.S. federal income tax considerations and other special considerations applicable to them. The senior debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail in an applicable prospectus supplement relating to any of the particular senior debt securities. An applicable prospectus supplement relating to specific senior debt securities will also describe any special considerations and any material additional tax considerations applicable to such senior debt securities.

When we refer to a series of senior debt securities, we mean a series issued under the indenture pursuant to which the senior debt securities will be issued. Each series of senior debt securities is a single distinct series under the indenture pursuant to which they will be issued and we may issue senior debt securities of each series in such amounts, at such times and on such terms as we wish. The senior debt securities of each series may differ from one another, and from any other series, in their terms, but all senior debt securities of a series together will constitute a single series for all purposes under the indenture pursuant to which they will be issued, except as described in the section “— Events of Default” below or the applicable prospectus supplements.

We may issue senior debt securities up to an aggregate principal amount as we may authorize from time to time. The applicable prospectus supplements will describe the terms of any series of senior debt securities being offered, including:

Market-Making Transactions

One or more of our subsidiaries may purchase and resell senior debt securities in market-making transactions after their initial issuance. We may also, subject to applicable law and any required regulatory approvals, purchase senior debt securities in the open market or in private transactions to be held by us or cancelled.

If you purchase securities issued before September 23, 2018 in a market making transaction, those securities will not be bail-inable securities, even though the applicable pricing supplement may not specify that your securities are not bail-inable securities.

Covenants

Except as otherwise provided in an applicable prospectus supplement with respect to any series of senior debt securities, we are not restricted by the indenture from incurring, assuming or becoming liable for any type of debt or other obligations, from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity, nor does it contain any covenants or other provisions that would limit our or our subsidiaries’ right to incur additional indebtedness, enter into any sale and leaseback transaction or grant liens on our or our subsidiaries’ assets. The indenture does not contain any provisions that would require us to repurchase or redeem or otherwise modify the terms of any of the senior debt securities upon a change in control or other events that may adversely affect the creditworthiness of the senior debt securities, for example, a highly leveraged transaction, except as otherwise specified in this prospectus or any applicable prospectus supplement.

Mergers and Similar Events

The indenture provides that we are permitted to merge, amalgamate, consolidate or otherwise combine with another entity, or to sell or lease substantially all of our assets to another entity, as long as the following conditions are met:

If the conditions described above are satisfied with respect to any series of debt securities, we will not need to obtain the consent of the holders of that series of debt securities in order to merge, amalgamate, consolidate or otherwise combine with another entity or to sell or lease substantially all of our assets.

We will not need to satisfy the conditions described above if we enter into other types of transactions, including:

It is possible that this type of transaction may result in a reduction in our credit rating, may reduce our operating results or may impair our financial condition. Holders of senior debt securities, however, will have no approval right with respect to any transaction of this type.

Modification and Waiver of the Senior Debt Securities

There are three types of changes we can make to the indenture and the senior debt securities issued under that indenture.

Changes Requiring Consent of Each Holder. First, there are changes that cannot be made to the indenture or the senior debt securities without the consent of each holder of a series of senior debt securities affected in any material respect by the change under the indenture. The following is a list of those types of changes:

Changes Requiring a Majority Consent. The second type of change to the indenture and the senior debt securities is the kind that requires the consent of holders of senior debt securities owning not less than a majority of the principal amount of the particular series affected. Most changes, including any change or elimination of any provision of the indenture and any modification of any right of the noteholders, fall into this category. A smaller class of changes does not require a majority consent, including clarifying changes and certain other changes that would not adversely affect in any material respect holders of the senior debt securities. We may also obtain a waiver of a past default from the holders of senior debt securities owning a majority of the principal amount of the particular series affected. However, we cannot obtain a waiver of a payment default or any other aspect of the indenture or the senior debt securities described above under “— Changes Requiring Consent of Each Holder” unless we obtain the individual consent of each holder of senior debt securities of the affected series to the waiver.

Changes Not Requiring Consent. The third type of change to the indenture and the senior debt securities does not require the consent by holders of senior debt securities. This type of change is limited to the issuance of new series of senior debt securities under the indenture, clarifications and certain other changes that would not adversely affect in any material respect the interests of the holders of the senior debt securities of any series.

We may also make changes or obtain waivers that do not adversely affect in any material respect a particular debt security, even if they affect other debt securities. In those cases, we do not need to obtain the approval of the holder of that debt security; we need only obtain any required approvals from the holders of the affected debt securities.

Modification of Bail-inable Debt Securities. Where an amendment, modification or other variance that can be made to the indenture or the bail-inable debt securities would affect the recognition of those bail-inable debt securities by the Superintendent of Financial Institutions (Canada) (the “Superintendent”) as TLAC (as defined below under “— Canadian Bank Resolution Powers”), that amendment, modification or variance will require the prior approval of the Superintendent.

Further Details Concerning Voting. When seeking consent, we will use the following rules to decide the principal amount to attribute to a senior debt security:

Senior debt securities will not be considered outstanding, and therefore not eligible to vote or take other action under the applicable indenture, if we have given a notice of redemption and deposited or set aside in trust for the holders money for the payment or redemption of those senior debt securities. Senior debt securities will also not be considered outstanding, and therefore not eligible to vote or take other action under the applicable indenture, if they have been fully defeased as described below under “— Defeasance — Full Defeasance” or if we or one of our affiliates is the beneficial owner of the senior debt securities.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding senior debt securities that are entitled to vote or take other action under the applicable indenture. In certain limited circumstances, the trustee will be entitled to set a record date for action by holders. If the trustee or we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding senior debt securities of that series on the record date. We or the trustee as applicable, may shorten or lengthen this period from time to time. This period, however, may not extend beyond the 180th day after the record date for the action.

Book-entry and other indirect holders should consult their banks, brokers or other financial institutions for information on how approval may be granted or denied if we seek to change the indenture or the senior debt securities or request a waiver.

Special Provisions Related to Bail-inable Debt Securities

The indenture provides for certain provisions applicable to bail-inable debt securities. The prospectus supplement and, if applicable, the relevant pricing supplement will describe the specific terms of bail-inable debt securities we may issue and specify whether or not your debt security is a bail-inable debt security.

Subject to certain exceptions discussed under “― Canadian Bank Resolution Powers,” including for certain structured notes, senior debt issued on or after September 23, 2018, with an initial or amended term to maturity (including explicit or embedded options) greater than 400 days, that is unsecured or partially secured and that has been assigned a CUSIP or ISIN or similar identification number, is 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 CIBC or any of its affiliates under the bail-in regime (as defined below under “— Canadian Bank Resolution Powers”), which we refer to as a “bail-in conversion.” We refer to debt securities that are subject to bail-in conversion as “bail-inable debt securities.”

By its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security is deemed to (i) agree to be bound, in respect of the bail-inable debt securities, by the CDIC Act, including the conversion of the bail-inable debt securities, 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 subsection 39.2(2.3) of the CDIC Act and the variation or extinguishment of the bail-inable debt securities in consequence, and by 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 bail-inable debt securities; (ii) attorn and submit to the jurisdiction of the courts in the Province of Ontario with respect to the CDIC Act and those laws; (iii) have represented and warranted that CIBC has not directly or indirectly provided financing to the holder or beneficial owner of the bail-inable debt securities for the express purpose of investing in the bail-inable debt securities; and (iv) acknowledge and agree that the terms referred to in clauses (i) and (ii) above, are binding on that holder or beneficial owner despite any provisions in the indenture or the bail-inable debt securities, any other law that governs the bail-inable debt securities and any other agreement, arrangement or understanding between that holder or beneficial owner and CIBC with respect to the bail-inable debt securities.

Holders and beneficial owners of bail-inable debt securities will have no further rights in respect of their bail-inable debt securities to the extent those bail-inable debt securities are converted in a bail-in conversion, other than those provided under the bail-in regime, and by its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security is deemed to irrevocably consent to the converted portion of the principal amount of that debt security and any accrued and unpaid interest thereon being deemed paid in full by CIBC by the issuance of common shares of CIBC (or, if applicable, any of its affiliates) upon the occurrence of a bail-in conversion, which bail-in conversion will occur without any further action on the part of that holder or beneficial owner or the trustee; provided that, for the avoidance of doubt, this consent will not limit or otherwise affect any rights that holders or beneficial owners may have under the bail-in regime.

Each holder or beneficial owner of a bail-inable debt security that acquires an interest in the bail-inable debt security in the secondary market and any successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of any holder or beneficial owner is deemed to acknowledge, accept, agree to be bound by and consent to the same provisions specified herein to the same extent as the holders or beneficial owners that acquired an interest in the bail-inable debt securities upon their initial issuance, including, without limitation, with respect to the acknowledgement and agreement to be bound by and consent to the terms of the bail-inable debt securities related to the bail-in regime.

Trustee and Trustee’s Duties

The trustee will undertake certain procedures and seek certain remedies in the event of an event of default or a default. See “— Events of Default” below. However, by its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security is deemed to acknowledge and agree that the bail-in conversion will not give rise to a default or event of default for purposes of Section 315(b) (Notice of Defaults) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act.

By its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security, to the extent permitted by the Trust Indenture Act, is deemed to waive any and all claims, in law and/or in equity, against the trustee, for, agrees not to initiate a suit against the trustee in respect of, and agrees that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the bail-in regime.

Additionally, by its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security is deemed to acknowledge and agree that, upon a bail-in conversion, or other action pursuant to the bail-in regime with respect to bail-inable debt securities,

Notwithstanding the foregoing, if, following the completion of a bail-in conversion, the relevant bail-inable debt securities remain outstanding (for example, if not all bail-inable debt securities are converted), then the trustee’s duties under the indenture will remain applicable with respect to those bail-inable debt securities following such completion to the extent that CIBC and the trustee will agree pursuant to a supplemental indenture or an amendment to the indenture; provided, however, that notwithstanding the bail-in conversion, there will at all times be a trustee for the bail-inable debt securities in accordance with the indenture, and the resignation and/or removal of the trustee, the appointment of a successor trustee and the rights of the trustee or any successor trustee will continue to be governed by the indenture, including to the extent no additional supplemental indenture or amendment to the indenture is agreed upon in the event the relevant bail-inable debt securities remain outstanding following the completion of the bail-in conversion.

DTC — Bail-in Conversion

Upon a bail-in conversion, we will provide a written notice to The Depository Trust Company (“DTC”) and the holders of bail-inable debt securities through DTC as soon as practicable regarding such bail-in conversion. CIBC will also deliver a copy of such notice to the trustee for information purposes.

By its acquisition of an interest in any bail-inable debt security, each holder or beneficial owner of that debt security is deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such bail-inable debt security to take any and all necessary action, if required, to implement the bail-in conversion or other action pursuant to the bail-in regime with respect to the bail-inable debt security as it may be imposed on it, without any further action or direction on the part of that holder or beneficial owner, the trustee or the paying agent.

Defeasance

The following discussion of full defeasance and covenant defeasance will be applicable to each series of senior debt securities that is denominated in U.S. dollars and has a fixed rate of interest and will apply to other series of senior debt securities if we so specify in the applicable prospectus supplements. Any defeasance or covenant defeasance with respect to bail-inable debt securities that would result in CIBC not meeting the TLAC requirements applicable to it pursuant to the TLAC Guideline (as defined below under “—Canadian Bank Resolution Powers”) will be subject to the prior approval of the Superintendent.

Full Defeasance. If there is a change in U.S. federal income tax law, as described below, we can legally release ourselves from any payment or other obligations on the senior debt securities of a series, called full defeasance, if we put in place the following other arrangements for holders to be repaid:

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment on the senior debt securities. You could not look to us for repayment in the event of any shortfall.

Covenant Defeasance. Even without a change in current U.S. federal income tax law, we can make the same type of deposit as described above, and we will be released from the restrictive covenants under the senior debt securities of a series that may be described in the applicable prospectus supplements. This is called covenant defeasance. In that event, you would lose the protection of these covenants but would gain the protection of having money and U.S. government, U.S. government agency or U.S. government-sponsored entity notes or bonds set aside in trust to repay the senior debt securities. In order to achieve covenant defeasance, we must do the following:

If we accomplish covenant defeasance, certain provisions of the indenture and the senior debt securities would no longer apply:

If we accomplish covenant defeasance, you can still look to us for repayment of the senior debt securities if there were a shortfall in the trust deposit. In fact, if one of the remaining events of default occurs (such as a bankruptcy) and the senior debt securities become immediately due and payable, there may be such a shortfall.

Events of Default

You will have special rights if an “event of default” occurs and is not cured, as described later in this subsection.

What is an Event of Default?

Under the indenture, for debt securities of a series issued on or after September 23, 2018, “event of default” means any of the following:

An event of default regarding one series of debt securities will not cause an event of default regarding any other series of debt securities. For purposes of this section “— Events of Default” with respect to debt securities issued on or after September 23, 2018, “series” refers to debt securities having identical terms, except as to issue date, principal amount and, if applicable, the date from which interest begins to accrue.

Notwithstanding the foregoing, if you purchase debt securities issued before September 23, 2018, or debt securities that are part of a series created before the date of this prospectus, “event of default” means any of the following:

A bail-in conversion will not constitute a default or an event of default under the indenture.

Remedies If an Event of Default Occurs. If an event of default occurs, the trustee will have special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the applicable indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in

conducting his or her own affairs. If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the outstanding senior debt securities of the affected series may declare the entire principal amount of (or, in the case of original issue discount securities, the portion of the principal amount that is specified in the terms of the affected senior debt security) and interest on all of the senior debt securities of that series to be due and immediately payable. This is called a “declaration of acceleration”. The declaration of acceleration is not, however, an automatic right upon the occurrence of an event of default, and for such acceleration to be effective, the trustee must take the aforementioned action or the holders must direct the trustee to act as described in this section below. Furthermore, a declaration of acceleration may be cancelled in certain circumstances, but only before a judgment or decree based on the acceleration has been obtained, by the holders of at least a majority in principal amount of the senior debt securities of the affected series. If any provisions of applicable U.S. or Canadian banking law prohibit the payment of any amounts due under the senior debt securities before a specified time, then the obligation to make such payment shall be subject to such prohibition.

Holders or beneficial owners of bail-inable debt securities may only exercise, or direct the exercise of, the rights described in this section if the Governor in Council (Canada) has not made an order under Canadian bank resolution powers pursuant to subsection 39.13(1) of the CDIC Act in respect of CIBC. Notwithstanding the exercise of those rights, bail-inable debt securities will continue to be subject to bail-in conversion until repaid in full.

You should read carefully the applicable prospectus supplements relating to any series of senior debt securities which are original issue discount securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount securities upon the occurrence of an event of default and its continuation.

Except in cases of default in which the trustee has the special duties described above, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection from expenses and liability called an indemnity satisfactory to the trustee. If such an indemnity is provided, the holders of a majority in principal amount of the outstanding senior debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture with respect to the senior debt securities of that series.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the senior debt securities, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your senior debt security on or after its due date.

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A REQUEST OF THE TRUSTEE AND TO MAKE OR CANCEL A DECLARATION OF ACCELERATION.

We will give to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture and the senior debt securities issued under it, or else specifying any default.

Form, Exchange and Transfer

Unless we specify otherwise in an applicable prospectus supplement, the senior debt securities will be issued:

If a senior debt security is issued as a registered global senior debt security, only the depositary will be entitled to transfer and exchange the senior debt security as described in this subsection because the depositary will be the sole registered holder of the senior debt security and is referred to below as the “holder.” Those who own beneficial interests in a global senior debt security do so through participants in the depositary’s securities clearance system, and the rights of these indirect owners will be governed by the applicable procedures of the depositary and its participants. We describe book-entry procedures below under “—Legal Ownership and Book-Entry Issuance.”

Holders of senior debt securities issued in fully-registered form may have their senior debt securities broken into more senior debt securities of smaller denominations of not less than US$1,000, or combined into fewer senior debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange.

Holders may exchange or register the transfer of senior debt securities at the office of the trustee. Senior debt securities may be transferred by endorsement. Holders may also replace lost, stolen or mutilated senior debt securities at that office. The trustee acts as our agent for registering senior debt securities in the names of holders and registering the transfer of senior debt securities. We may change this appointment to another entity or perform it ourselves. The entity performing the role of maintaining the list of registered holders is called the security registrar. It will also record transfers. The trustee may require an indemnity before replacing any senior debt securities.

Holders will not be required to pay a service charge to register the transfer or exchange of senior debt securities, but holders may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The registration of a transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If we designate additional agents, they will be named in the applicable prospectus supplements. We may cancel the designation of any particular agent. We may also approve a change in the office through which any agent acts.

If the senior debt securities are redeemable and we redeem less than all of the senior debt securities of a particular series, we may block the registration of transfer or exchange of senior debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders entitled to receive the mailing. We may also refuse to register transfers or exchanges of senior debt securities selected for redemption, except that we will continue to permit registration of transfers and exchanges of the unredeemed portion of any senior debt security being partially redeemed.

The Trustee

The trustee makes no representation or warranty, whether express or implied, with respect to CIBC or the senior debt securities and other matters described in this prospectus. The trustee has not prepared or reviewed any of the information included in this prospectus, except the trustee has consented to the use of its name. Such approval does not constitute a representation or approval by the trustee of the accuracy or sufficiency of any information contained in this prospectus.

Canadian Bank Resolution Powers

General

Under Canadian bank resolution powers, the CDIC may, in circumstances where CIBC has ceased, or is about to cease, to be viable or in certain other circumstances, assume temporary control or ownership of CIBC and may be granted broad powers by one or more orders of the Governor in Council (Canada), each of which we refer to as an “Order,” 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. As part of the Canadian bank resolution powers, certain provisions of and regulations under the Bank Act, the CDIC Act and certain other Canadian federal statutes pertaining to banks, which we refer to collectively as the “bail-in regime,” provide for a bank recapitalization regime for banks designated by the Superintendent as “domestic systemically important banks,” or “D-SIBs,” which include CIBC.

The expressed objectives of the bail-in regime include reducing government and taxpayer exposure in the unlikely event of a failure of a D-SIB, reducing the likelihood of such a failure by increasing market discipline and reinforcing that bank shareholders and creditors are responsible for the D-SIBs’ risks and not taxpayers, and preserving financial stability by empowering the CDIC to quickly restore a failed D-SIB to viability and allow it to remain open and operating, even where the D-SIB has experienced severe losses.

Under the CDIC Act, in circumstances where the Superintendent is of the opinion that CIBC has ceased, or is about to cease, to be viable and viability cannot be restored or preserved by exercise of the Superintendent’s powers under the Bank Act, or in certain other circumstances specified in the CDIC Act, the Superintendent, after providing CIBC with a reasonable opportunity to make representations, is required to provide a report to CDIC. Following receipt of the Superintendent’s report, CDIC may request the Minister of Finance for Canada (the “Minister of Finance”) to recommend that the Governor in Council (Canada) make an Order and, if the Minister of Finance is of the opinion that it is in the public interest to do so, the Minister of Finance may recommend that the Governor in Council (Canada) make, and on that recommendation, the Governor in Council (Canada) may make, one or more of the following Orders:

Following a vesting order or receivership order, CDIC will assume temporary control or ownership of CIBC and will be granted broad powers under that Order, 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.

Under a bridge bank order, CDIC has the power to transfer CIBC’s insured deposit liabilities and certain assets and other liabilities of CIBC to a bridge institution. Upon the exercise of that power, any assets and liabilities of CIBC that are not transferred to the bridge institution would remain with CIBC, which would then be wound up. In such a scenario, any liabilities of CIBC, including any outstanding debt securities (whether or not such debt securities are bail-inable debt securities), that are not assumed by the bridge institution could receive only partial or no repayment in the ensuing wind-up of CIBC.

Upon the making of a conversion order, prescribed shares and liabilities under the bail-in regime that are subject to that conversion order will, to the extent converted, be converted into common shares of CIBC or any of its

affiliates, as determined by CDIC. Subject to certain exceptions discussed below, senior debt issued on or after September 23, 2018, with an initial or amended term to maturity (including explicit or embedded options) greater than 400 days, that is unsecured or partially secured and that has been assigned a CUSIP or ISIN or similar identification number is subject to a bail-in conversion. Shares, other than common shares, and subordinated debt of CIBC are also subject to a bail-in conversion, unless they are non-viability contingent capital.

Shares and liabilities which would otherwise be bail-inable but were issued before September 23, 2018 are not subject to a bail-in conversion unless, in the case of any such liability, including any debt securities, the terms of that liability are amended to increase the principal amount or to extend the term to maturity on or after September 23, 2018, and that liability, as amended, meets the requirements to be subject to a bail-in conversion. Covered bonds, certain derivatives and certain structured notes (as such term is used under the bail-in regime) are expressly excluded from a bail-in conversion. To the extent that any debt securities constitute structured notes (as such term is used under the bail-in regime) they will not be bail-inable debt securities. As a result, claims of some creditors whose claims would otherwise rank equally with those of the holders holding bail-inable debt securities would be excluded from a bail-in conversion and thus the holders and beneficial owners of bail-inable debt securities will have to absorb losses ahead of these other creditors as a result of the bail-in conversion. The terms and conditions of the bail-in conversion will be determined by CDIC in accordance with and subject to certain requirements discussed below.

Bail-in Conversion

Under the bail-in regime there is no fixed and pre-determined contractual conversion ratio for the conversion of the bail-inable debt securities, or other shares or liabilities of CIBC that are subject to a bail-in conversion, into common shares of CIBC or any of its affiliates nor are there specific requirements regarding whether liabilities subject to a bail-in conversion are converted into common shares of CIBC or any of its affiliates. CDIC determines the timing of the bail-in conversion, the portion of bail-inable shares and liabilities to be converted and the terms and conditions of the conversion, subject to parameters set out in the bail-in regime. Those parameters include that:

Compensation Regime

The CDIC Act provides for a compensation process for holders of bail-inable debt securities who immediately prior to the making of an Order, directly or through an intermediary, own bail-inable debt securities that are converted in a bail-in conversion. While this process applies to successors of those holders it does not apply to assignees or transferees of the holder following the making of the Order and does not apply if the amounts owing under the relevant bail-inable debt securities are paid in full.

Under the compensation process, the compensation to which such holders are entitled is the difference, to the extent it is positive, between the estimated liquidation value and the estimated resolution value of the relevant bail-inable debt securities. The liquidation value is the estimated value the holders of bail-inable debt securities would have received if an order under the Winding-up and Restructuring Act (Canada) had been made in respect of CIBC, as if no Order had been made and without taking into consideration any assistance, financial or otherwise, that is or may be provided to CIBC, directly or indirectly, by CDIC, the Bank of Canada, the Government of Canada or a province of Canada, after any order to wind up CIBC has been made.

The resolution value in respect of relevant bail-inable debt securities is the aggregate estimated value of the following: (a) the relevant bail-inable debt securities, if they are not held by CDIC and they are not converted, after the making of an Order, into common shares under a bail-in conversion; (b) common shares that are the result of a bail-in conversion after the making of an Order; (c) any dividend or interest payments made, after the making of the Order, with respect to the relevant bail-inable debt securities to any person other than CDIC; and (d) any other cash, securities or other rights or interests that are received or to be received with respect to the relevant bail-inable debt securities as a direct or indirect result of the making of the Order and any actions taken in furtherance of the Order, including from CDIC, CIBC, the liquidator of CIBC, if CIBC is wound up, the liquidator of a CDIC subsidiary incorporated or acquired by order of the Governor in Council (Canada) for the purposes of facilitating the acquisition, management or disposal of real property or other assets of CIBC that CDIC may acquire as the result of its operations that is liquidated or the liquidator of a bridge institution if the bridge institution is wound up.

In connection with the compensation process, CDIC is required to estimate the liquidation value and the resolution value in respect of the portion of converted bail-inable debt securities and is required to consider the difference between the estimated day on which the liquidation value would be received and the estimated day on which the resolution value is, or would be, received.

CDIC must, within a reasonable period following a bail-in conversion, make an offer of compensation by notice to the relevant holders that held bail-inable debt securities equal to, or in value estimated to be equal to, the amount of compensation to which such holders are entitled or provide a notice stating that such holders are not entitled to any compensation. In either case, such offer or notice is required to include certain prescribed information, including important information regarding the rights of such holders to seek to object and have the compensation to which they are entitled determined by an assessor (a Canadian Federal Court judge) where holders of liabilities representing at least 10% of the principal amount and accrued and unpaid interest of the liabilities of the same class object to the offer or absence of compensation. The period for objecting is limited (45 days following the day on which a summary of the notice is published in the Canada Gazette) and failure by holders holding a sufficient principal amount plus accrued and unpaid interest of affected bail-inable debt securities to object within the prescribed period will result in the loss of any ability to object to the offered compensation or absence of compensation, as applicable. CDIC will pay the relevant holders the offered compensation within 135 days after the date on which a summary of the notice is published in the Canada Gazette if the offer of compensation is accepted, the holder does not notify CDIC of acceptance or objection to the offer or if the holder objects to the offer but the 10% threshold described above is not met within the aforementioned 45-day period.

Where an assessor is appointed, the assessor could determine a different amount of compensation payable, which could either be higher or lower than the original amount. The assessor is required to provide holders, whose compensation it determines, notice of its determination. The assessor’s determination is final and there are no further opportunities for review or appeal. CDIC will pay the relevant holders the compensation amount determined by the assessor within 90 days of the assessor’s notice.

By its acquisition of an interest in any bail-inable debt securities, each holder or beneficial owner of that debt security is deemed to agree to be bound by a bail-in conversion and so will have no further rights in respect of its bail-inable debt securities to the extent those bail-inable debt securities are converted in a bail-in conversion, other than those provided under the bail-in regime.

A similar compensation process to the one set out above applies, in certain circumstances, where as a result of CDIC’s exercise of bank resolution powers, notes are assigned to an entity which is then wound-up.

TLAC Guideline

In connection with the bail-in regime, the OSFI guideline (the “TLAC Guideline”) on Total Loss Absorbing Capacity (“TLAC”) applies to and establishes standards for D-SIBs, including CIBC. Under the TLAC Guideline, beginning November 1, 2021, CIBC is required to maintain a minimum capacity to absorb losses composed of unsecured external long-term debt that meets the prescribed criteria or regulatory capital instruments to support recapitalization in the event of a failure. Bail-inable debt securities and regulatory capital instruments that meet the prescribed criteria will constitute TLAC of CIBC.

In order to comply with the TLAC Guideline, our indenture provides for terms and conditions for the bail-inable debt securities necessary to meet the prescribed criteria and qualify at their issuance as TLAC instruments of CIBC under the TLAC Guideline. Those criteria include the following:

Payment and Paying Agents

We will pay interest to the person listed in the trustee’s records at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the senior debt security on the interest due date. That particular day, which will be the business day immediately preceding the interest due date unless otherwise stated in the applicable pricing supplement, is called the regular record date. Holders buying and selling senior debt securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the one who is the registered holder on the regular record date. The most common manner is to adjust the sale price of the senior debt securities to prorate interest fairly between buyer and seller. This prorated interest amount is called accrued interest.

We will pay interest, principal and any other money due on the senior debt securities at the office of the paying agent or such other office as may be agreed upon. Holders must make arrangements to have their payments picked up at or wired from that office or such other office as may be agreed upon. We may also choose to pay interest by mailing checks.

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW THEY WILL RECEIVE PAYMENTS.

We may also arrange for additional payment offices and may cancel or change these offices, including our use of the trustee’s corporate trust offices. These offices are called paying agents. We may also choose to act as our own paying agent or choose one of our subsidiaries to do so. We must notify holders of changes in the paying agents for any particular series of senior debt securities.

Conversion or Exchange of Senior Debt Securities

If and to the extent mentioned in the applicable prospectus supplement, any series of senior debt securities may be optionally or mandatorily convertible or exchangeable for stock or other securities of CIBC or another entity or entities, into the cash value therefor or into any combination of the above. The specific terms on which any senior debt securities series may be so converted or exchanged (as well as any material U.S. and Canadian federal income tax considerations) will be described in the applicable prospectus supplement. These terms may include provisions for conversion or exchange, either mandatory, at the holder’s option or at our option, in which case the amount or number of securities the senior debt securities holders would receive would be calculated at the time and manner described in the applicable prospectus supplement.

Notices

We and the trustee will send notices regarding the senior debt securities only to registered holders, using the address as listed in the trustee’s records. With respect to who is a registered “holder” for this purpose, see “—Legal Ownership and Book-Entry Issuance.”

Regardless of who acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount is due to holders will be repaid to us. After that two-year period, holders may look to us for payment and not to the trustee or any other paying agent.

Governing Law

The indenture and the senior debt securities will be governed by New York law, except that, pursuant to the indenture, the ranking of the senior debt securities and the provisions relating to the bail-in acknowledgment of holders and beneficial owners of bail-inable debt securities will be governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein.

Legal Ownership and Book-Entry Issuance

In this section, we describe special considerations that will apply to registered senior debt securities issued in global i.e., book-entry, form. First we describe the difference between registered ownership and indirect ownership of registered senior debt securities. Then we describe special provisions that apply to global senior debt securities.

Who Is the Legal Owner of a Registered Security?

Each senior debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global senior debt securities representing senior debt securities. We refer to those who have senior debt securities registered in their own names, on the books that we or the trustee maintains for this purpose, as the “registered holders” of those senior debt securities. Subject to limited exceptions, we and the trustee are entitled to treat the registered holder of a senior debt security as the person exclusively entitled to vote, to receive notices, to receive any interest or other payment in respect of the senior debt security and to exercise all the rights and power as an owner of the senior debt security. We refer to those who own beneficial interests in senior debt securities that are not registered in their own names as “indirect owners” of those senior debt securities. As we discuss below, indirect owners are not registered holders, and investors in senior debt securities issued in book-entry form or in street name will be indirect owners.

Book-Entry Owners. Unless otherwise noted in an applicable prospectus supplement, we will issue each senior debt security in book-entry form only. This means senior debt securities will be represented by one or more global senior debt securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, in turn, hold beneficial interests in the senior debt securities on behalf of themselves or their customers.

Under the indenture, subject to limited exceptions and applicable law, only the person in whose name a senior debt security is registered is recognized as the holder of that senior debt security. Consequently, for senior debt securities issued in global form, we will recognize only the depositary as the holder of the senior debt securities and we will make all payments on the senior debt securities, including deliveries of any property other than cash, to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the senior debt securities.

As a result, investors will not own senior debt securities directly. Instead, they will own beneficial interests in a global senior debt security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the senior debt securities are issued in global form, investors will be indirect owners, and not registered holders, of the senior debt securities.

Street Name Owners. We may issue senior debt securities initially in non-global form or we may terminate an existing global senior debt security, as described below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” In these cases, investors may choose to hold their senior debt securities in their own names or in street name. Senior debt securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those senior debt securities through an account he or she maintains at that institution.

For senior debt securities held in street name, we will, subject to limited exceptions and applicable law, recognize only the intermediary banks, brokers and other financial institutions in whose names the senior debt securities are registered as the holders of those senior debt securities, and we will make all payments on those senior debt securities, including deliveries of any property other than cash, to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold senior debt securities in street name will be indirect owners, not registered holders, of those senior debt securities.

Registered Holders. Subject to limited exceptions, our obligations, as well as the obligations of the trustee under any indenture and the obligations, if any, of any other third parties employed by us, run only to the registered holders of the senior debt securities. We do not have obligations to investors who hold beneficial interests in global senior debt securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect owner of a senior debt security or has no choice because we are issuing the senior debt securities only in global form.

For example, once we make a payment or give a notice to the registered holder, we have no further responsibility for that payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect owners but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose — for example, to amend the indenture for a series of senior debt securities or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture — we would seek the approval only from the registered holders, and not the indirect owners, of the relevant senior debt securities. Whether and how the registered holders contact the indirect owners is up to the registered holders.

When we refer to “you” in this prospectus, we mean all purchasers of the senior debt securities being offered by this prospectus and the applicable prospectus supplements, whether they are the registered holders or only indirect owners of those senior debt securities. When we refer to “your senior debt securities” in this prospectus, we mean the senior debt securities in which you will hold a direct or indirect interest.

Special Considerations for Indirect Owners. If you hold senior debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

What Is a Global Security?

Unless otherwise noted in the applicable prospectus supplement, we will issue each senior debt security in book-entry form only. Each senior debt security issued in book-entry form will be represented by a global senior debt security that we deposit with and register in the name of one or more financial institutions or clearing systems, or their nominees, which we select. A financial institution or clearing system that we select for any senior debt security for this purpose is called the “depositary” for that senior debt security. A senior debt security will usually have only one depositary but it may have more. Each series of senior debt securities will have one or more of the following as the depositaries:

The depositaries named above may also be participants in one another’s systems. Thus, for example, if DTC is the depositary for a global senior debt security, investors may hold beneficial interests in that senior debt security through Euroclear or Clearstream, as DTC participants. The depositary or depositaries for your senior debt securities will be named in the applicable prospectus supplements; if none is named, the depositary will be DTC.

A global senior debt security may represent one or any other number of individual senior debt securities. Generally, all senior debt securities represented by the same global senior debt security will have the same terms. We may, however, issue a global senior debt security that represents multiple senior debt securities of the same kind, such as senior debt securities that have different terms and are issued at different times. We call this kind of global senior debt security a master global senior debt security. The applicable prospectus supplements will not indicate whether your senior debt securities are represented by a master global senior debt security.

A global senior debt security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all senior debt securities represented by a global senior debt security, and investors will be permitted to own only indirect interests in a global senior debt security. Indirect interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose senior debt security is represented by a global senior debt security will not be a holder of the senior debt security, but only an indirect owner of an interest in the global senior debt security.

If an applicable prospectus supplement for a particular senior debt security indicates that the senior debt security will be issued in global form only, then the senior debt security will be represented by a global senior debt security at all times unless and until the global senior debt security is terminated. We describe the situations in which this can occur below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” If termination occurs, we may issue the senior debt securities through another book-entry clearing system or decide that the senior debt securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities. As an indirect owner, an investor’s rights relating to a global senior debt security will be governed by the account rules of the depositary and those of the investor’s bank, broker, financial institution or other intermediary through which it holds its interest (such as Euroclear or Clearstream, if DTC is the depositary), as well as general laws relating to securities transfers. We do not recognize this type of investor or any intermediary as a holder of senior debt securities and instead deal only with the depositary that holds the global senior debt security.

If senior debt securities are issued only in the form of a global senior debt security, an investor should be aware of the following:

Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated. If we issue any series of senior debt securities in book-entry form but we choose to give the beneficial owners of that series the right to obtain non-global senior debt securities, any beneficial owner entitled to obtain non-global senior debt securities may do so by following the applicable procedures of the depositary, any transfer agent or registrar for that series and that owner’s bank, broker or other financial institution through which that owner holds its beneficial interest in the senior debt securities. If you are entitled to request a non-global certificate and wish to do so, you will need to allow sufficient lead time to enable us or our agent to prepare the requested certificate.

In addition, in a few special situations described below, a global senior debt security will be terminated and interests in it will be exchanged for certificates in non-global form representing the senior debt securities it represented. After that exchange, the choice of whether to hold the senior debt securities directly or in street name will be up to the investor. Investors must consult their own banks, brokers or other financial institutions, to find out how to have their interests in a global senior debt security transferred on termination to their own names, so that they will be holders. We have described the rights of holders and street name investors above under “— Who Is the Legal Owner of a Registered Security?”.

The special situations for termination of a global senior debt security are as follows:

If a global senior debt security is terminated, only the depositary, and neither we nor the trustee for any senior debt securities, is responsible for deciding the names of the institutions in whose names the senior debt securities represented by the global senior debt security will be registered and, therefore, who will be the registered holders of those senior debt securities.

Considerations Relating to DTC

DTC has informed us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that DTC participants deposit with DTC. DTC also facilitates the post-trade settlement among DTC participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between DTC participants’ accounts. This eliminates the need for physical movement of securities certificates. DTC participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. The rules applicable to DTC and DTC participants are on file with the SEC.

Purchases of senior debt securities within the DTC system must be made by or through DTC participants, which will receive a credit for the senior debt securities on DTC’s records. The ownership interest of each actual acquirer of new securities is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which they entered into the transaction. Transfers of ownership interests in the senior debt securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in securities, except in the event that use of the book-entry system for the securities is discontinued.

To facilitate subsequent transfers, the securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities; DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to its direct participants, by its direct participants to indirect participants, and by its direct and indirect participants to beneficial owners of the securities will be governed by arrangements among them, respectively, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the senior debt securities are being redeemed, DTC will determine the amount of the interest of each direct participant to be redeemed in accordance with its then current procedures.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the senior debt securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts such senior debt securities are credited on the record date (identified in a listing attached to the omnibus proxy).

Distribution payments on the senior debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s usual practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detailed information from the issuer or agent on the relevant payment date in accordance with their respective holdings shown on DTC’s records. Payments by DTC participants to beneficial owners will be governed by standing instructions and customary practices and will be the responsibility of such participants and not of DTC, the agent or the issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of distributions to Cede & Co. (or other nominee as may be requested by an authorized representative of DTC) is the responsibility of the issuer or agent, disbursements of such payments to direct participants are the responsibility of DTC, and disbursements of such payments to the beneficial owners are the responsibility of direct and indirect participants.

DTC may discontinue providing its services as depository with respect to the securities at any time by giving reasonable notice to the issuer or agent. Under such circumstances, in the event that a successor depository is not obtained, security certificates are required to be printed and delivered.

CIBC may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, security certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof. We do not have any responsibility for the performance by DTC or its participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

Considerations Relating to Euroclear and Clearstream

Euroclear and Clearstream are securities clearing systems in Europe. Both systems clear and settle securities transactions between their participants through electronic, book-entry delivery of securities against payment.

Euroclear and Clearstream may be depositaries for a global senior debt security. In addition, if DTC is the depositary for a global senior debt security, Euroclear and Clearstream may hold interests in the global senior debt security as participants in DTC.

As long as any global senior debt security is held by Euroclear or Clearstream, as depositary, you may hold an interest in the global senior debt security only through an organization that participates, directly or indirectly, in Euroclear or Clearstream. If Euroclear or Clearstream is the depositary for a global senior debt security and there is no depositary in the United States, you will not be able to hold interests in that global senior debt security through any securities clearance system in the United States.

The information in this section concerning Euroclear and Clearstream and each of their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof. Payments, deliveries, transfers, exchanges, notices and other matters relating to the senior debt securities made through Euroclear or Clearstream must comply with the rules and procedures of those clearing systems. Those clearing systems could change their rules and procedures at any time. We have no control over those clearing systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on one hand, and participants in DTC, on the other hand, when DTC is the depositary, would also be subject to DTC’s rules and procedures.

Special Timing Considerations Relating to Transactions in Euroclear and Clearstream. Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any senior debt securities held through those clearing systems only on days when those clearing systems are open for business. Those clearing systems may not be open for business on days when banks, brokers and other financial institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the senior debt securities through those clearing systems and wish to transfer their interests, or to receive or make a payment or

delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than would be the case for transactions within one clearing system.
