Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 104. Acts of Holders; Record Dates . Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Bank. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Bank, if made in the manner provided in this Section.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

For the purposes of this Indenture, the ownership of Securities shall be proved by the Security Register.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Bank in reliance thereon, whether or not notation of such action is made upon such Security.

The Bank may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Bank may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Bank from setting a new record date for any action for which a record date has

8

previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Bank, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Bank’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Bank in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106.

With respect to any record date set pursuant to this Section, the party hereto that sets such record date may designate any day as the “ Expiration Date ” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto that set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph; provided that the Expiration Date shall not be later than the 180th day after such record date.

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

and any such request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document shall be deemed received only upon actual receipt thereof.

In respect of this Indenture, the Trustee shall not have any duty or obligation to verify or confirm that the Person sending instructions, directions, reports, notices or other communications or information by electronic transmission is, in fact, a Person authorized to give such instructions, directions, reports, notices or other communications or information on behalf of the party purporting to send such electronic transmission; and the Trustee shall not have any liability for any losses, liabilities, costs or expenses incurred or sustained by any party as a result of such reliance upon or compliance with such instructions, directions, reports, notices or other communications or information. Each other party agrees to assume all risks arising out of the use of electronic methods to submit instructions, directions, reports, notices or other communications or information to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, notices, reports or other communications or information, and the risk of interception and misuse by third parties.

Section 106. Notice to Holders; Waiver . Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his or her address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

10

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Section 107. Conflict with Trust Indenture Act . If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Section 108. Effect of Headings and Table of Contents . The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 109. Successors and Assigns . All covenants and agreements in this Indenture by the Bank shall bind its successors and assigns, whether so expressed or not.

Section 110. Separability Clause . In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 113. Legal Holidays . In any case where any Interest Payment Date, Redemption Date, Repayment Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repayment Date, or at the Stated Maturity; provided , however , that no interest shall accrue on such amount for the period from and after such Interest Payment Date, Redemption Date, Repayment Date, or Stated Maturity, as the case may be, to the date of such payment.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, including in the event that the size of a series of Outstanding Securities is increased as contemplated by Section 301, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 301 or the Bank Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee, by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Bank, and the Bank shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 304. Temporary Securities . Pending the preparation of definitive Securities of any series, the Bank may execute, and upon Bank Order the Trustee shall authenticate and deliver, temporary Securities that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Bank executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities of any series are issued, the Bank will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Bank in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Bank shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor.

23

Section 305. Registration, Registration of Transfer and Exchange . The Bank shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Bank in a Place of Payment being herein sometimes collectively referred to as the “ Security Register ”) in which, subject to such reasonable regulations as it may prescribe, the Bank shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “ Security Registrar ” for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Security of a series at the office or agency of the Bank in a Place of Payment for that series, the Bank shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Bank shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Bank, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Bank or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Bank and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Bank or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906, 1107 or 1303 not involving any transfer.

If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Bank shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

The provisions of Clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

(1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

(2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for registered Securities, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary has notified the Bank that it is unwilling or unable or no longer permitted under applicable law to continue as Depositary for such Global Security and the Bank does not appoint another institution to act as Depositary within 60 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security, (C) the Bank so directs the Trustee by a Bank Order or (D) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301.

(3) Subject to Clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

(4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906, 1107 or 1303 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities . If any mutilated Security is surrendered to the Trustee, the Bank shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Bank and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Bank or the Trustee that such Security has been acquired by a protected purchaser in good faith, the Bank shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

25

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Bank in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Bank may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Bank, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 307. Payment of Interest; Interest Rights Preserved . Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid to the Trustee by 10:00 a.m. (local time at the Place of Payment) on any Interest Payment Date shall be paid on such Interest Payment Date to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Bank, at its election in each case, as provided in Clause (1) or (2) below:

(1) The Bank may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Bank shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Bank shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Bank of such Special Record Date and, in

26

the name and at the expense of the Bank, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Bank may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Bank to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308. Persons Deemed Owners . Prior to due presentment of a Security for registration of transfer, the Bank, the Trustee and any agent of the Bank or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Bank, the Trustee nor any agent of the Bank or the Trustee shall be affected by notice to the contrary.

Section 309. Cancellation . All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Bank may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Bank may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Bank has not issued and sold, and all Securities so delivered shall, upon the written direction of the Bank, be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary procedures.

Section 310. Computation of Interest . Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. For disclosure purposes under the Interest Act (Canada), whenever in this Indenture or any Securities issued hereunder interest at a specified rate is to be calculated on the basis of a period less than a calendar year, the yearly rate of interest to which such rate is equivalent is such rate multiplied by the actual number of days in the relevant calendar year and divided by the number of days in such period.

27

Section 311. CUSIP Numbers . The Bank in issuing any series of the Securities may use CUSIP numbers, if then generally in use, and thereafter with respect to such series, the Trustee may use such numbers in any notice of redemption with respect to such series, provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities of that series or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities of that series, and any such redemption shall not be affected by any defect in or omission of such numbers. The Bank shall promptly notify the Trustee in writing of any change in the CUSIP numbers.

Section 312. Original Issue Discount . If any of the Securities is an Original Issue Discount Security, the Bank shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on such Outstanding Original Issue Discount Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

Section 402. Application of Trust Money .

29

(3) if the Bank shall become insolvent or bankrupt or subject to the provisions of the Winding-Up and Restructuring Act of Canada, or go into liquidation either voluntarily or under an order of a court of competent jurisdiction, or otherwise acknowledge its insolvency ( provided that a resolution or order for winding-up the Bank, with a view to its consolidation, amalgamation or merger with another bank or the transfer of its assets as an entirety to such other bank, as provided in Article Eight, shall not constitute an event of default under this Section 501 if such last-mentioned bank shall, as a part of such consolidation, amalgamation, merger or transfer, and, within 90 days from the passing of the resolution or the date of the order for the winding-up or liquidation of the Bank or within such further period of time as may be allowed by the Trustee, comply with the conditions to that end stated in Article Eight); or

(4) any other Event of Default provided with respect to Securities of that series.

Section 502. Acceleration of Maturity; Rescission and Annulment . If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) and accrued and unpaid interest on all the Securities of that series to be due and payable immediately, by a notice in writing to the Bank (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Bank and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Bank has paid or deposited with the Trustee a sum sufficient to pay:

(A) all overdue interest on all Securities of that series,

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;

and

30

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 503. Suits for Enforcement by Trustee . If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

In case of any judicial proceeding relative to the Bank (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 607.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided , however , that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Section 505. Trustee May Enforce Claims Without Possession of Securities . All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 506. Application of Money Collected . Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

31

(4) the Trustee for 90 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 90-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders) or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

Section 508. Unconditional Right of Holders to Receive Principal, Premium and Interest . Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or repayment, on the Redemption Date or date for repayment, as the case may be) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

32

Section 509. Restoration of Rights and Remedies .

Section 510. Rights and Remedies Cumulative . Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 511. Delay or Omission Not Waiver . No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 512. Control by Holders . The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that:

(1) in the payment of the principal of or any premium or interest on any Security of such series, or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 514. Undertaking for Costs . In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess reasonable costs (including legal fees and expenses) against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Bank or by the Trustee.

Section 515. Waiver of Usury, Stay or Extension Laws . The Bank covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Bank (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

The Trustee, any Paying Agent, any Security Registrar or any other agent of the Bank, in their individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Bank with the same rights they would have if they were not Trustee, Paying Agent, Security Registrar or such other agent.

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee (in addition to the compensation for its services) in accordance with any provision of this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or willful misconduct;

38

(4) when the Trustee incurs any expenses or renders any services in connection with an Event of Default specified in Section 501(3), such expenses (including the reasonable charges and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under the Winding-Up and Restructuring Act of Canada or any similar Canadian or United States federal or state law for the relief of debtors;

Section 609. Corporate Trustee Required; Eligibility . There shall at all times be a Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $15,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign promptly in the manner and with the effect hereinafter specified in this Article.

Section 610. Resignation and Removal; Appointment of Successor . No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611.

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Bank. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may, at the expense of the Bank, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

39

The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Bank. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may, at the expense of the Bank, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

If at any time:

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Bank or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Bank or by any such Holder, or

(3) the Trustee shall become incapable of acting or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Bank by a Board Resolution or other appropriate Bank authorization may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee.

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Trustee for any cause, with respect to the Securities of one or more series, the Bank shall promptly appoint a successor Trustee with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Bank and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Bank. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Bank or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

40

The Bank shall give notice of each resignation and each removal of a Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

Section 611. Acceptance of Appointment by Successor . In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Bank and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Bank or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Bank, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and that (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Bank or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

Upon request of any such successor Trustee, the Bank shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

41

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Section 612. Merger, Conversion, Consolidation or Succession to Business . Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee (including this transaction), shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion, consolidation or sale to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 613. Preferential Collection of Claims Against Bank . If and when the Trustee shall be or become a creditor of the Bank (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Bank (or any such other obligor).

Section 614. Appointment of Authenticating Agent . The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Bank and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $15,000,000 and subject to supervision or examination by federal or state authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or

42

consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent (including the authenticating agency contemplated by this Indenture), shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Bank. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Bank. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent that shall be acceptable to the Bank and shall give notice of such appointment in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Bank agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Section 615. Not Bound to Act . The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any

43

applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days written notice to the Bank, provided that (i) the Trustee’s written notice shall describe the circumstances of such non-compliance; and (ii) if such circumstances are rectified to the Trustee’s satisfaction within such 10 day period, then such resignation shall not be effective.

If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Holder of such series of Securities or of all series of Securities or of all series of Securities whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 702 a copy of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender the Trustee shall mail to such applicants and file with the Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interest of the relevant Holders or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application.

Every Holder of Securities, by receiving and holding the same, agrees with the Bank and the Trustee that neither the Bank nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant to the Trust Indenture Act.

A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange upon which any Securities are listed, with the Commission and with the Bank. The Bank will promptly notify the Trustee in writing when any Securities are listed on any stock exchange and of any delisting thereof.

Section 704. Reports by Bank . The Bank shall file with the Trustee and the Commission, and transmit to Holders, such information, documents and other reports as may be required by the Trust Indenture Act; provided that any such information, documents or reports filed electronically with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be deemed filed with, and delivered to, the Trustee at the same time as filed with the Commission; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed pursuant to the “EDGAR” system (or its successor).

Delivery of such reports, information and documents to the Trustee is for informational purposes only and shall not constitute a representation or warranty as to the accuracy or completeness of the reports, information or documents.

The Bank will deposit with the Paying Agent money in immediately available funds sufficient to pay such amounts, provided that if the Bank is acting as a Paying Agent, it will, on or before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in this Indenture. In each case the Bank will promptly notify the Trustee in writing of its compliance with this paragraph.

Section 1002. Maintenance of Office or Agency . The Bank will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Bank in respect of the Securities of that series and this Indenture may be served. The Bank will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Bank shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at such location as determined by the Bank and the Trustee.

The Bank may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided , however , that no such designation or rescission shall in any manner relieve the Bank of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Bank will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Trustee is hereby appointed as Paying Agent for the Securities.

50

If the Bank issues Securities of any series through a branch, agency or office other than its head or home office, the Bank represents that, notwithstanding the place of booking office or jurisdiction of incorporation or organization of the Bank, the obligations of the Bank in respect of such Securities are the same as if it had issued such Securities through its head or home office.

Section 1003. Money for Securities Payments to Be Held in Trust . If the Bank shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before 10:00 a.m. (local time at the Place of Payment) on each due date of the principal of or any premium or interest on any of the Securities of that series, deposit in an account established for the purpose of providing the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Bank shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Bank will promptly notify the Trustee of its action or failure so to act.

The Bank will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Bank (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

The Bank may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Bank Order direct any Paying Agent to pay, to the Trustee all sums held by the Bank or such Paying Agent, such sums to be held by the Trustee in trust for the benefit of the Persons entitled thereto; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Bank on Bank Request; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Bank for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, shall thereupon cease.

51

Section 1004. Statement by Officers as to Default . The Bank will deliver to the Trustee, within 120 days after the end of each fiscal year of the Bank ending after the date hereof, an Officer’s Certificate, stating whether or not to the best knowledge of the signatory thereof the Bank is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Bank shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

Section 1005. Existence . Subject to Article Eight, the Bank will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 1006. Waiver of Certain Covenants . Subject to Section 502 and Section 902, and except as otherwise specified as contemplated by Section 301 for Securities of such series, the Bank may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 301(c)(18), 901(2) or 901(7) for the benefit of the Holders of such series or in Section 1005 if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Bank and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

(3) In the event of an election to have Section 1403 apply to any Securities or any series of Securities, as the case may be, the Bank shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for U.S. federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to U.S. federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.

59

(5) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of the Trust Indenture Act).

(6) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Bank is a party or by which it is bound.

(7) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under the Investment Company Act or exempt from registration thereunder.

(8) The Bank shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with (in each case, subject to the satisfaction of the condition in clause (4)).

Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Bank from time to time upon Bank Request any money or U.S. Government Obligations held by it as provided in Section 1404 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

Section 1406. Reinstatement .

60

Bank has been discharged or released pursuant to Section 1402 or 1403 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1405 with respect to such Securities in accordance with this Article; provided , however , that if the Bank makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Bank shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

September 25, 2012

Wells Fargo Securities, LLC

375 Park Avenue, 4 ^th Floor

New York, New York 10152

Ladies and Gentlemen:

Canadian Imperial Bank of Commerce, a Canadian chartered bank (“CIBC”), proposes to issue and sell from time to time equity-linked, commodity-linked, currency-linked, interest rate-linked and other structured Medium-Term Notes (such series of securities being hereinafter referred to as the “Series” and any securities to be issued from time to time as part of such Series being hereinafter referred to individually as a “Security” and collectively as the “Securities”), in an aggregate amount up to U.S. $2,000,000,000 or the equivalent thereof in other currencies or currency units and agrees with the Agent as set forth in this Agreement. Wells Fargo Securities, LLC (“WFS” or the “Agent”) may, from time to time, offer Securities as agent of CIBC or purchase Securities from CIBC as principal for the Agent’s own account. The Agent agrees that it will only do so in accordance with Applicable Law (as defined below) in all material respects and the conditions provided herein.

Subject to the terms and conditions stated herein and to the reservation by CIBC of the right to sell Securities directly on its own behalf, CIBC hereby (i) appoints the Agent as an agent of CIBC for the purpose of soliciting and receiving offers to purchase Securities from CIBC when and as instructed by CIBC pursuant to Section 3(a) hereof and (ii) agrees that, except as otherwise contemplated herein, whenever it is agreed between CIBC and the Agent that CIBC will sell Securities directly to the Agent as principal, CIBC and the Agent will enter into a separate agreement (each a “Terms Agreement”), substantially in the form of Exhibit A hereto or in such other form as may be agreed by the parties to that particular agreement (which may be an oral agreement, if confirmed in writing by electronic transmission or otherwise), relating to such sale in accordance with Section 3(b) hereof. This Agreement shall not be construed to create either an obligation on the part of CIBC to sell any Securities or an obligation of the Agent to purchase Securities as principal or otherwise participate in any particular offering of Securities.

The Securities will be issued under an indenture, dated as of September 15, 2012 (the “Indenture”), between CIBC and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”). The Securities shall have such terms, including the right (if any) to repayment of principal, the right (if any) to payment of interest, redemption provisions (if any) and other

terms set forth in the Prospectus referred to below as it may be amended or supplemented from time to time. The Securities will be issued, and the terms and rights thereof established, from time to time by CIBC in accordance with the Indenture.

1.  Representations and Warranties of CIBC . CIBC represents and warrants to, and agrees with, the Agent as of the date hereof (the “Commencement Date”), as of each date the Agent solicits offers to purchase Securities, as of the date of each acceptance by CIBC of an offer for the purchase of Securities (whether to the Agent as principal or through the Agent as agent) (the “Acceptance Date”), as of the Time of Sale (as defined below), as of the date of each delivery of Securities (whether to the Agent as principal or through the Agent as agent) (the “Settlement Date”), and as of any time that the Registration Statement (as defined below) or the Prospectus (as defined below) shall be amended or supplemented (other than by an amendment or supplement providing solely for the establishment of or a change in the interest rates, maturity or price of Securities or similar changes), or there is filed with the Commission any document incorporated by reference into the Prospectus (other than any Form 6-K relating exclusively to the issuance of debt securities under the Registration Statement other than the Securities) (each of the times referenced above being referred to herein as a “Representation Date”) as follows: provided , however , that as of the Commencement Date (as defined below) CIBC does not represent and warrant with respect to the Time of Sale, the Time of Sale Information (as defined below) or the Issuer Free Writing Prospectus (as defined below) that:

(a) CIBC meets the requirements for use of Form F-3 (“Form F-3”) under the Securities Act of 1933, as amended, and the rules and regulations of the U.S. Securities and Exchange Commission (the “Commission”) thereunder (collectively, the “Act”), and has filed a registration statement including a prospectus on Form F-3 (File No. 333-180771) in respect of securities (the “Shelf Securities”) with the Commission. As of any time, the various parts of such registration statement and any post-effective amendment thereto, including all exhibits thereto, any information in a form of prospectus, prospectus supplement and/or pricing supplement that is deemed or retroactively deemed to be a part of such registration statement, as amended, pursuant to Rule 430B under the Act (which information shall be considered to be included in such registration statement, as amended, as of the time specified in Rule 430B under the Act) that has not been superseded or modified and the documents incorporated by reference therein at the time such part of the registration statement became effective, but excluding Form T-1, each as amended at the time such part of such registration statement became effective, are hereinafter collectively called the “Registration Statement.” Such Registration Statement (including any pre-effective amendment thereto) and any post-effective amendment thereto, each in the form heretofore delivered to the Agent, including all documents incorporated by reference in the prospectus contained therein as of the date of such prospectus, have been declared effective by the Commission in such form and continue to be effective. As of the Commencement Date, no other document with respect to such Registration Statement or document incorporated by reference therein has heretofore been filed or transmitted for filing with the Commission, except for any documents filed with the Commission subsequent to the date of such effectiveness and available on the Commission’s website.

The prospectus covering the Shelf Securities dated May 4, 2012, included in such Registration Statement, in the form first used to confirm sales of the Securities (or in the form first made available to the Agent by CIBC to meet requests of purchasers pursuant to Rule 173 under the Act) is hereinafter referred to as the “Basic Prospectus.”

2

The Basic Prospectus, as supplemented by the prospectus supplement, dated September 25, 2012 (the “Prospectus Supplement”) specifically relating to the Securities, in the form first used to confirm sales of the Securities (or in the form first made available to the Agent by CIBC to meet requests of purchasers pursuant to Rule 173 under the Act), is hereinafter referred to as the “Program Prospectus.”

The Program Prospectus, as supplemented by a pricing prospectus supplement that sets forth only the terms of a particular issue of the Securities (together with the accompanying product prospectus supplement that sets forth terms common to one or more particular issues of the Securities (if applicable), a “Pricing Supplement”), in the form first used to confirm sales of the applicable issue of Securities (or in the form first made available to the Agent by CIBC to meet requests of purchasers pursuant to Rule 173 under the Act) is hereinafter referred to as the “Prospectus.”

The term “Preliminary Prospectus” means any preliminary form of the Prospectus. If a preliminary Pricing Supplement is not used in connection with any particular offering of the Securities, the term “Preliminary Prospectus” means the Program Prospectus and any applicable product prospectus supplement. If CIBC and the Agent agree that the preliminary terms of any Securities shall be conveyed to investors by means of a free writing prospectus (as defined pursuant to Rule 405 under the Act) rather than by means of a preliminary Pricing Supplement, each such free writing prospectus is referred to herein as a “Preliminary Term Sheet.” If CIBC and the Agent agree to use a free writing prospectus to convey the final terms of any Securities to investors prior to delivering the Prospectus to investors, each such free writing prospectus is referred to herein as a “Final Term Sheet.”

Any reference herein to any Preliminary Prospectus or Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, as of the date of such Preliminary Prospectus or Prospectus, as the case may be, and as of any applicable Representation Date.

Any reference herein to any amendment or supplement to any Preliminary Prospectus or Prospectus shall be deemed to refer to and include any documents filed after the date of such Preliminary Prospectus or Prospectus, as the case may be, under the U.S. Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference in such Preliminary Prospectus or Prospectus, as the case may be.

Any reference herein to the Prospectus as amended or supplemented shall be deemed to refer to the Prospectus as amended or supplemented in relation to the Securities in the form in which it is filed with the Commission in accordance with Section 5(a) hereof, including any documents incorporated by reference therein as of the date of such filing.

(b) At or prior to the Time of Sale, CIBC had prepared the following information (collectively, the “Time of Sale Information”): the Preliminary Prospectus, any applicable Preliminary Term Sheet and any applicable Final Term Sheet, together with any pricing information CIBC shall convey to the Agent in writing prior to the Time of Sale for oral communication by the Agent to its customers. “Time of Sale” means, with respect to Securities of a particular tranche, the time agreed to by CIBC and the Agent (whether acting as principal or agent) as the time of the pricing of the Securities of that tranche, which, unless otherwise agreed, shall be the time immediately after CIBC and the Agent agree on the pricing terms of such Securities.

(c) The documents incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus, as amended or supplemented, when they were filed with the Commission, complied in all material respects with the requirements of the Act and the Exchange Act, as applicable, and none of such documents, as of their respective issue dates, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading; and any further documents so filed and incorporated by reference in the Registration Statement, the Time of Sale Information or the Prospectus or any further amendment or supplement thereto, when such documents are filed with the Commission, will comply in all material respects with the Act and the Exchange Act, as applicable, and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to be make the statements therein, in the light of the circumstances in which they were made, not misleading; provided , however , that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to CIBC relating to the Agent or its affiliates by or on behalf of the Agent expressly for use in the Registration Statement, the Time of Sale Information or the Prospectus as amended or supplemented relating to a particular issuance of Securities;

(d) The Registration Statement, the Time of Sale Information and the Prospectus comply and, as amended or supplemented, if applicable, will comply as of the time of such amendment or supplement, in all material respects with the Act and, if applicable, the U.S. Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and as to the Registration Statement and any amendment thereto, do not and will not, as of the applicable effective date of the Registration Statement and such amendment and as of each Representation Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading and, as to the Prospectus and any amendment or supplement thereto, do not and will not, as of their dates and applicable filing dates and as of each Representation Date, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided , however , that this representation and warranty shall not apply to (i) any statements or omissions made in reliance upon and in conformity with information furnished in writing to CIBC relating to the Agent or its affiliates by or on behalf of the Agent expressly for use in the Prospectus as amended or supplemented, relating to a particular issuance of Securities or (ii) that part of the Registration Statement that shall constitute the Statement of Eligibility under the Trust Indenture Act (Form T-1) of the Trustee;

(e) As of the relevant Time of Sale for any particular offering of Securities, the Time of Sale Information does not, and at the Settlement Date, will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided , however , that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to CIBC relating to the Agent or its affiliates by or on behalf of the Agent expressly for use in such Time of Sale Information.

4

The term “broadly available road show” means a “bona fide electronic road show” as defined in Rule 433(h)(5) under the Act that has been made available without restriction to any person. Each such Issuer Free Writing Prospectus complied in all material respects with the Act, has been filed in accordance with the Act (to the extent required thereby) and, when taken together with the Preliminary Prospectus, as amended and supplemented, most recently filed prior to first use of such Issuer Free Writing Prospectus, did not, and as of each Representation Date will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided , however , that this representation and warranty shall not apply to any statements or omissions made in each such Issuer Free Writing Prospectus in reliance upon and in conformity with information furnished in writing to CIBC relating to the Agent or its affiliates by or on behalf of the Agent expressly for use in any Issuer Free Writing Prospectus.

3. Appointment as Agent .

(a) On the basis of the representations and warranties herein contained, and subject to the terms and conditions herein set forth, if the Agent agrees to participate as Agent in an offering of a particular Security or Securities, the Agent hereby agrees, upon receipt of instructions from CIBC, to act as agent of CIBC and to use its reasonable efforts to solicit and receive offers to purchase such Security or Securities from CIBC upon the terms and conditions set forth in the Time of Sale Information and the Prospectus as amended or supplemented from time to time. The Agent shall solicit offers to purchase only Securities having such terms, and shall solicit such offers only during such periods, as CIBC and the Agent shall agree upon.

The Agent shall be the exclusive agent in connection with the offer and sale of any particular Security or Securities that the Agent has been instructed to offer by CIBC during such periods as CIBC and the Agent shall agree upon. From the time of the receipt by the

8

Agent of instructions from CIBC to act as Agent in connection with any particular Securities to the earlier of the settlement date for such Securities and the end of the period referred to in the prior sentence, CIBC shall not offer or sell such Securities, or any substantially similar Securities, other than through the Agent. It is understood that if from time to time CIBC is approached by a prospective agent offering to solicit a specific purchase of Securities and the Agent has not received instructions from CIBC, at or prior to such time, to act as Agent in connection with such Securities or substantially similar Securities (unless the settlement date for such Securities has already occurred), CIBC may enter into an agreement with such agent with respect to such specific purchase upon such terms as CIBC and such agent may agree. These provisions shall not limit Section 5(f) hereof or any similar provision included in any Terms Agreement.

CIBC reserves the right, in its sole discretion, at any time when the Agent has agreed to solicit offers to purchase the Securities, to instruct the Agent to suspend, for any period of time or permanently, the solicitation of offers to purchase the Securities. As soon as practicable, but in any event not later than one business day in New York City, after receipt of notice from CIBC, the Agent will suspend solicitation of offers to purchase Securities from CIBC until such time as CIBC has instructed the Agent to resume such solicitation. During such period, CIBC shall not be required to comply with the provisions of Sections 5(i), 5(j), 5(k), 5(l) and 5(m) with regard to the Agent. Upon advising the Agent that such solicitation may be resumed, however, CIBC shall simultaneously provide the documents (if any) required to be delivered by Sections 5(i), 5(j), 5(k), 5(l) and 5(m) and the Agent shall have no obligation to solicit offers to purchase the Securities until such documents have been received by the Agent. In addition, any failure by CIBC to comply with its obligations hereunder, including its obligations to deliver the documents required by Sections 5(i), 5(j), 5(k), 5(l) and 5(m) with regard to the Agent shall automatically terminate the Agent’s obligations hereunder, including its obligations to solicit offers to purchase the Securities hereunder as agent or to purchase Securities hereunder as principal.

CIBC agrees to pay the Agent a commission, at the time of settlement of any sale of a Security by CIBC as a result of a solicitation made by the Agent, in such amount as may be agreed between the Agent and CIBC and as set forth in the Prospectus as amended and supplemented under the caption “Supplemental Plan of Distribution.”

(a) CIBC agrees to indemnify and hold harmless the Agent, its affiliates, directors, officers, employees and agents and each person, if any, who controls the Agent within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “Wells Fargo Indemnified Parties”), from and against any and all losses, claims, damages and liabilities (including, without limitation, attorneys’ fees), as incurred, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or Time of Sale Information or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon and in conformity with information relating to the Agent or its affiliates furnished in writing to CIBC by the Agent expressly for use therein.

(b) The Agent agrees to indemnify and hold harmless CIBC, its directors, officers, employees, agents, its authorized representative or representatives in the United States, and each person, if any, who controls CIBC within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “CIBC Indemnified Parties”), from and against any and all losses, claims, damages and liabilities (including, without limitation, attorneys’ fees), as incurred, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or Time of Sale Information or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, but only with reference to information furnished in writing by the Agent relating to the Agent or its affiliates expressly for use in the Registration Statement, the Time of Sale Information, any Issuer Free Writing Prospectus, the Prospectus or any Preliminary Prospectus, in each case as amended or supplemented, (ii) any untrue statement or alleged untrue statement of a material fact contained in any Agent Free Writing Prospectus or any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except to the extent that the information in such Agent Free Writing Prospectus is based upon and in conformity in all material respects with the information included or incorporated by reference in the applicable Preliminary Prospectus or Prospectus or any applicable Issuer Free Writing Prospectus and (iii) any breach, or any allegation of conduct that, if proved, would be a breach, of any of the representations, warranties and agreements in Section 2 hereof by the Agent.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party

and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding; provided, however, that the failure to notify promptly the indemnifying party will not relieve it from liability unless and to the extent that such failure results in the forfeiture by the indemnifying party of substantial rights or defenses. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Agent in the case of parties indemnified pursuant to Section 9(a) and by CIBC in the case of parties indemnified pursuant to Section 9(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is an actual or potential party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in Sections 9(a) and 9(b) hereof is unavailable as a matter of law to an indemnified party in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under either such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by CIBC on the one hand, and the Agent on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of CIBC on the one hand, and of the Agent on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by CIBC on the one hand, and the Agent on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by CIBC bear to the total underwriting commissions received by the Agent, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of CIBC and of the Agent shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by CIBC or by the Agent relating to the Agent or its affiliates and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

19

(e) CIBC and the Agent agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Agent were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, the Agent shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 9 (i) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity and (ii) shall be available as provided in this Section 9 regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any person.

10. Agency; No Fiduciary Relationship .

(a) The Agent, in soliciting offers to purchase Securities from CIBC and in performing the other obligations of the Agent hereunder (other than in respect of any purchase by the Agent as principal, pursuant to a Terms Agreement or otherwise), is acting solely as agent for CIBC and not as principal. The Agent will make reasonable efforts to assist CIBC in obtaining performance by each purchaser whose offer to purchase Securities from CIBC was solicited by the Agent and has been accepted by CIBC, but the Agent shall not have any liability to CIBC in the event such purchase is not consummated for any reason. If CIBC shall default on its obligation to deliver Securities to a purchaser whose offer it has accepted, CIBC shall (i) hold the Agent harmless against any loss, claim or damage arising from or as a result of such default by CIBC and (ii) notwithstanding such default, pay to the Agent that solicited such offer any commission to which it would be entitled in connection with such sale.

(b) CIBC acknowledges and agrees that the Agent is acting solely in the capacity of an arm’s length contractual counterparty to CIBC with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to CIBC or any other person; additionally, the Agent is not advising CIBC or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction; CIBC shall consult with its own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Agent shall have no responsibility or liability to CIBC with respect thereto; any review by the Agent of CIBC, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Agent and shall not be on behalf of CIBC.

11. Survival of Certain Representations and Obligations . Notwithstanding any termination of this Agreement (y) this Agreement shall remain in full force and effect with respect to the rights and obligations of any party which have previously accrued or which relate to Securities which are already issued, agreed to be issued or the subject of a pending

20

offer at the time of such suspension or termination and (z) in any event, this Agreement shall remain in full force and effect insofar as the third paragraph of Section 3(a), and Sections 5(d), 5(e), 7, 9, 10, 11, 13, 15, 16, 18 and 19 hereof are concerned. All provisions of this Agreement shall survive delivery of and payment for any of the Securities.

12. Suspension or Termination; Amendments .

(a) This Agreement (excluding any Terms Agreement) may be terminated at any time by CIBC or by the Agent upon the giving of written notice of such suspension or termination to the Agent or CIBC, as the case may be.

(b) CIBC and the Agent may amend any provision of this Agreement. Any such amendment shall be made in a writing signed by CIBC and the Agent.

13. Notices . All statements, requests, notices and agreements hereunder shall be in writing, and if to the Agent shall be delivered or sent by mail, facsimile transmission or e-mail to the address of Wells Fargo Securities, LLC, 375 Park Avenue, 4 ^th Floor, New York, New York 10152, Attn: Don Brudie, Managing Director, Facsimile: (212) 214-8917, e-mail: don.brudie@wellsfargo.com (or to such other address, facsimile number or e-mail address as CIBC shall be notified by the Agent); and if to CIBC shall be delivered to Canadian Imperial Bank of Commerce, Commerce Court, Toronto, Ontario M5L 1A2, Facsimile: (416) 980-7012, Attention: Corporate Secretary, e-mail: corporate.secretary@cibc.com (or to such other address, facsimile number or e-mail address as the Agent shall be notified by CIBC) with a copy to: Blake, Cassels & Graydon LLP, 199 Bay Street, Suite 2800, Commerce Court, Toronto, Ontario M5L 1A9, Facsimile: (416) 863-2653, Attention: Ernest D. McNee, e-mail: ernest.mcnee@blakes.com and Mayer Brown LLP, 71 S. Wacker Drive, Chicago, Illinois 60606, Facsimile: (312) 701-7711, Attention: Edward S. Best, e-mail: ebest@mayerbrown,com. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. Patriot Act . In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Agent is required to obtain, verify and record information that identifies their respective clients, including CIBC, which information may include the name and address of their respective clients, as well as other information that will allow the Agent to properly identify their respective clients.

15. Successors . This Agreement and any Terms Agreement shall be binding upon, and inure solely to the benefit of, the Agent and CIBC, and to the extent provided in Sections 9 and 10 hereof, the CIBC Indemnified Parties and the Wells Fargo Indemnified Parties, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any Terms Agreement. No purchaser of any of the Securities through or from the Agent hereunder shall be deemed a successor or assign by reason merely of such purchase.

16. Jurisdiction . CIBC irrevocably (i) agrees that any legal suit, action or proceeding against CIBC brought by the Agent or by any person who controls the Agent arising out of or based upon this Agreement or any Terms Agreement or the transactions contemplated hereby and thereby may be instituted in any state or federal court in The City of New York (a “New York Court”), (ii) waives, to the fullest extent it may effectively do so, any objection that it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the jurisdiction of such courts in any such suit, action or

21

proceeding. CIBC irrevocably waives any immunity to jurisdiction to which it may otherwise be entitled or become entitled (including sovereign immunity, immunity to pre-judgment attachment, post-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement and any Terms Agreement or the transactions contemplated hereby and thereby that is instituted in any New York Court. CIBC has appointed CIBC World Markets Corp., 425 Lexington Avenue, New York, New York 10017, Attention: General Counsel, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement and any Terms Agreement or the transactions contemplated hereby and thereby that may be instituted in any New York Court by the Agent or by any person who controls the Agent, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. CIBC represents and warrants that the Authorized Agent has agreed to act as such agent for service of process and agrees to take any and all action, including the filing of any and all documents and instruments, which may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to CIBC shall be deemed, in every respect, effective service of process upon CIBC.

17. Business Day . Time shall be of the essence in this Agreement and any Terms Agreement. As used herein, “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

18. Judgment Currency . If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Agent could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of CIBC with respect to any sum due from it to the Agent or any Wells Fargo Indemnified Party shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by the Agent or Wells Fargo Indemnified Party of any sum in such other currency, and only to the extent that the Agent or Wells Fargo Indemnified Party may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to the Agent or Wells Fargo Indemnified Party hereunder, CIBC agrees as a separate obligation and notwithstanding any such judgment, to indemnify the Agent or Wells Fargo Indemnified Party against such loss. If the United States dollars so purchased are greater than the sum originally due to the Agent or Wells Fargo Indemnified Party hereunder, the Agent or Wells Fargo Indemnified Party agrees to pay to CIBC an amount equal to the excess of the dollars so purchased over the sum originally due to the Agent or Wells Fargo Indemnified Party hereunder.

19. Governing Law . This Agreement and any Terms Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to any law thereof that would result in the application of the law of any other jurisdiction.

20. Counterparts . This Agreement and any Terms Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.
