Section 1.4 ACTS OF HOLDERS.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of the Outstanding Securities of all series or one or more series, as the case may be, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Corporation. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 6.2 hereof) conclusive in favor of the Trustee and the Corporation, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 15.6.

(b) 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 authority. The fact

16

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 and in accordance with such reasonable rules as the Trustee may determine, and the Trustee may in any instance require further proof with respect to any of the matters referred in this Section.

(c) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of commencement and the date of termination of holding the same, shall be proved by the Security Register.

(d) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank or other depositary, wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Corporation may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or
(3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved in any other manner that the Trustee deems sufficient.

(e) If the Corporation shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Corporation may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Corporation shall have no obligation to do so. Notwithstanding Section 316(c) of the Trust Indenture Act, such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; PROVIDED that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

(f) 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

17

therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Corporation in reliance thereon, whether or not notation of such action is made upon such Security.

Section 1.5 NOTICES, ETC., TO TRUSTEE AND CORPORATION.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other documents provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or by the Corporation shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust/Global Finance Unit, or

(2) the Corporation by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Corporation addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Corporation.

Section 1.6 NOTICE TO HOLDERS; WAIVER.

Where this Indenture provides for notice of any event to Holders of Registered Securities by the Corporation or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities 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 of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

In case, by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impractical to mail notice of any event to Holders of Registered Securities when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be directed by the Corporation shall be deemed to be sufficient giving of such notice for every purpose hereunder.

Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 3.1, where this Indenture provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper in The City of New York and in such other city or cities as, may be specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice. Any such notice shall be deemed to have been given on the date of the first such publication.

18

In case, by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause, it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders of every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the sufficiency of any notice to Holders of Registered Securities given as provided herein.

Any request, demand, authorization, direction, notice, consent or waiver or other Act required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

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.

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

applicable, be governed by such provisions.

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 excluded, as the case may be.

Section 1.12 LEGAL HOLIDAY.

In any case where any Interest Payment Date, Redemption Date, sinking fund payment date or Stated Maturity or 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 any Security other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section), payment of principal (or premium, if any) or interest, 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 or Redemption Date or sinking fund payment date, or at the Stated Maturity or Maturity; PROVIDED that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be.

The Corporation further agrees to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of CT Corporation System in full force and effect so long as any of the Securities shall be outstanding.

To the extent that the Corporation has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, the Corporation hereby irrevocably waives such immunity in respect of its obligations under this Indenture and the Securities, to the extent permitted by law.

(ii) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment referred to in (i) above is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Corporation shall pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the Judgment Currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Required Currency originally due.

(b) In the event of the winding-up of the Corporation at any time while any amount or damages owing under the Securities and this Indenture, or any judgment or order, rendered in respect thereof, shall remain outstanding, the Corporation shall indemnify and hold the Holders of Securities and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the equivalent of the amount in the Required Currency (other than under this Subsection (b)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this Subsection (b) the final date for the filing of proofs of claim in the winding-up of the Corporation shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Corporation may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

(c) The obligations contained in Subsections (a)(ii) and (b) of this Section shall constitute separate and independent obligations of the Corporation from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Corporation shall apply irrespective of any waiver or extension granted by any Holder or Trustee from time to time and shall continue in full force and effect

21

notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Corporation for a liquidated sum in respect of amounts due hereunder (other than under Subsection (b) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Corporation or the applicable liquidator. In the case of Subsection (b) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

(d) The term "RATE(S) OF EXCHANGE" shall mean, if the Canadian Currency is the Judgment Currency and United States Currency is the Required Currency, or vice versa the Bank of Canada noon rate for purchases on the relevant date of the Required Currency with the Judgment Currency, as reported by Telerate on screen 3194 (or such other means of reporting the Bank of Canada noon rate as may be agreed upon by the Corporation and the Trustee) and includes any premiums and costs of exchange payable.

Section 2.3 SECURITIES ISSUABLE IN GLOBAL FORM.

If Securities of or within a series are issuable in global form, as specified as contemplated by Section 3.1, then, notwithstanding clause
(10) of Section 3.1, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such series from time to time endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Corporation Order to be delivered to the Trustee pursuant to Section 3.3 or Section 3.4. Subject to the provisions of Section 3.3 and, if applicable,
Section 3.4, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Corporation Order. If a Corporation Order pursuant to Section 3.3 or Section 3.4 has been, or simultaneously is, delivered, any instructions by the Corporation with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 1.2 and need not be accompanied by an Opinion of Counsel.

The provisions of the last sentence of Section 3.3 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Corporation and the Corporation delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 1.2 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 3.3.

Notwithstanding the provisions of Section 3.7, unless otherwise specified as contemplated by Section 3.1, payment of principal of (and premium, if any) and interest, if any,

24

on any Security in permanent global form shall be made to the Person or Persons specified therein.

Notwithstanding the provisions of Section 3.9 and except as provided in the preceding paragraph, the Corporation, the Trustee and any agent of the Corporation or the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a permanent global Security (i) in the case of a permanent global Security in registered form, the Holder of such permanent global Security in registered form, or (ii) in the case of a permanent global Security in bearer form, Euroclear or Clearstream.

Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

Section 3.3 EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

The Securities and any Coupons appertaining thereto shall be executed on behalf of the Corporation by any two officers of the Corporation, under its corporate seal reproduced thereon or otherwise. The signature of any of these officers on the Securities or Coupons may be the manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities or Coupons.

Securities or Coupons bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Corporation shall bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or Coupons or did not hold such offices at the date of such Securities or Coupons.

At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Securities of any series together with any Coupon appertaining thereto, executed by the Corporation to the Trustee for authentication, together with a Corporation Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Corporation Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the United States; and PROVIDED FURTHER that, unless otherwise specified with respect to any series of Securities pursuant to Section 3.1, a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in Exhibit B-1 to this Indenture, dated no earlier than 15 days prior to the earlier of the date on which such

29

Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security, then, for purposes of this Section and
Section 3.4, the notation of a beneficial owner's interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial owner's interest in such permanent global Security. Except as permitted by Section 3.6, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant Coupons for interest then matured have been detached and cancelled. If not all the Securities of any series are to be issued at one time and if the Board Resolution, Officers' Certificate or supplemental indenture establishing such series shall so permit, such Corporation Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, Stated Maturity, date of issuance and date from which interest shall accrue.

In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel stating:

(a) that the form or forms of such Securities and any Coupons have been established in conformity with the provisions of this Indenture;

(b) that the terms of such Securities and any Coupons have been established in conformity with the provisions of this Indenture;

(c) that such Securities together with any Coupons appertaining thereto, when completed by appropriate insertions and executed and delivered by the Corporation to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Corporation in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legal, valid and binding obligations of the Corporation, enforceable against the Corporation in accordance with their terms, subject to (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer and other similar laws of general applicability relating to or affecting the enforcement of creditors' rights, (ii) general equitable principles and (iii) such other qualifications as such counsel shall conclude do not materially affect the rights of Holders of such Securities and any Coupons;

(d) that all laws and requirements in respect of the execution and delivery by the Corporation of such Securities, any Coupons and of the supplemental indentures, if any, have been complied with and that authentication and delivery of such Securities any Coupons and the execution and delivery of the supplemental indenture, if any, by the Trustee will not violate the terms hereunder;

30

(e) that the Corporation has the corporate power to issue such Securities and any Coupons and has duly taken all necessary corporate action with respect to such issuance; and

(f) that the issuance of such Securities and any Coupons will not contravene the articles of incorporation or by-laws of the Corporation.

Notwithstanding the provisions of Section 3.1 and of the preceding two paragraphs, if not all the Securities of any series are to be issued at one time, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 3.1 or the Corporation Order and Opinion of Counsel otherwise required pursuant to the preceding two paragraphs prior to or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series.

The Trustee shall not be required to authenticate and deliver any 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.

Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated by Section 3.1.

No Security or Coupon 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 duly executed by the Trustee by manual signature of a Responsible Officer, 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 Corporation, and the Corporation shall deliver such Security to the Trustee for cancellation as provided in Section 3.10 together with a written statement (which need not comply with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Corporation, 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 3.4 TEMPORARY SECURITIES.

Pending the preparation of definitive Securities of any series, the Corporation may execute, and upon Corporation Order the Trustee shall authenticate and deliver, temporary Securities which 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, in registered form or, if authorized, in bearer form with one or more Coupons or without Coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

31

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if temporary Securities of any series are issued, the Corporation 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 such series upon surrender of the temporary Securities of such series at the office or agency of the Corporation 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 (accompanied by the unmatured Coupons appertaining thereto), the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations; PROVIDED, HOWEVER, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and PROVIDED FURTHER that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 3.3. 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.

If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London, England office of a depositary or common depositary (the "COMMON DEPOSITARY"), for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security (the "EXCHANGE DATE"), the Corporation shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Corporation. On or after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Corporation's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 3.1, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; PROVIDED, HOWEVER, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euroclear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global Security held for its account then to be exchanged, each in the form set forth in Exhibit B-2 to this Indenture (or in such other form as may be established pursuant to Section 3.1); and PROVIDED, FURTHER, that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security only in compliance with the requirements of Section 3.3.

32

Unless otherwise specified in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear or Clearstream, as the case may be, a certificate in the form set forth in Exhibit B-1 to this Indenture (or in such other form as may be established pursuant to Section 3.1), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like in the event that such Person does not take delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global security shall be deliverable only outside the United States.

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 3.1, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee of a certificate or certificates in the form set forth in Exhibit B-2 to this Indenture (or in such other form as may be established pursuant to Section 3.1), for credit without further interest thereon on or after such Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date in the form set forth in Exhibit B-1 to this Indenture (or in such other form as may be established pursuant to Section 3.1). Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this
Section and of the third paragraph of Section 3.3 of this Indenture and the interests of the Persons who are the beneficial owners of the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange Date or the date of certification if such date occurs after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or interest, if any, owing with respect to a beneficial interest in a temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear and Clearstream and not paid as herein provided shall be returned to the Trustee no later than one month prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Corporation in accordance with Section 10.3.

Section 3.5 REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

33

The Corporation shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Registered Securities (the registers maintained in the Corporate Trust Office of the Trustee and in any other office or agency of the Corporation 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 Corporation shall provide for the registration of Registered Securities and of transfers of Securities. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Security Register for each series shall be open to inspection by the applicable security registrar (the "SECURITY REGISTRAR"). The Trustee is hereby initially appointed as Security Registrar for the purpose of registering Registered Securities and transfers of Registered Securities as herein provided. The Corporation shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; PROVIDED, THAT, no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Registered Securities shall have been appointed by the Corporation and shall have accepted such appointment by the Corporation. In the event that the Trustee shall not be or shall cease to be the Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for such series of Securities. Notwithstanding the foregoing, to the extent required under applicable law, the Corporation agrees to maintain at its registered office in Canada or any other place in Canada designated by the board of directors, a central securities register (which shall not be a Securities Register hereunder), wherein the Corporation shall record information derived from the Securities Register and other information required by applicable law.

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

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Registered Securities, which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to any series of Securities as contemplated by Section 3.1, Bearer Securities may not be issued in exchange for Registered Securities.

If (but only if) expressly permitted in or pursuant to the applicable Board Resolution and (subject to Section 3.3) set forth in the applicable Officers' Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 3.1, at the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured

34

Coupon or Coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Corporation in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Corporation and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; PROVIDED, HOWEVER, that, except as otherwise provided in Section 10.2, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

Whenever any Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.1, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent global Security is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 3.1 and PROVIDED that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Corporation shall deliver to the Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner's interest in such permanent global Security, executed by the Corporation. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Corporation Order with respect thereto to the Trustee, as the Corporation's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged, which (unless such Securities of the series are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the global Security shall be issuable only in the form in which the Securities are

35

issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof; PROVIDED, HOWEVER, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption; and PROVIDED, FURTHER, that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

If at any time the Depositary for Securities of a series notifies the Corporation that it is unwilling, unable or no longer qualifies to continue as Depositary for Securities of such series or if at any time the Depositary for Securities for such series shall no longer be registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Corporation shall appoint a successor depositary with respect to the Securities for such series. If a successor to the Depositary for Securities is not appointed by the Corporation within 90 days after the Corporation receives such notice or becomes aware of such condition, as the case may be, the Corporation's election pursuant to Section 3.1 shall no longer be effective with respect to the Securities for such series and the Corporation will execute, and the Trustee, upon receipt of a Corporation Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

If an Event of Default, under Section 5.1 hereof, occurs and is continuing, then the Securities of any series issued in the form of one or more global Securities shall no longer be represented by such global Security or Securities. In addition, the Corporation may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more global Securities shall no longer be represented by such global Security or Securities. In either such event the Corporation will execute, and the Trustee, upon receipt of a Corporation Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

Upon the exchange of a global Security for Securities in definitive registered form, such global Security shall be cancelled by the Trustee. Securities issued in exchange for a global Security pursuant to this
Section shall be registered in such names and in such authorized

36

denominations as the depositary for such global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Securities to the persons in whose names such Securities are so registered.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Corporation 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 Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Corporation or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Corporation 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 Corporation 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 3.4, 9.6, 11.7 or 13.5 not involving any transfer.

The Corporation shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of that series under Section 11.3 or 12.3 and ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that, to the extent provided with respect to such Bearer Security, such Bearer Security may be exchanged for a Registered Security of that series and like tenor; PROVIDED that such Registered Security shall be immediately surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture, or
(iv) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

Section 3.6 MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

If any mutilated Security or a Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, the Corporation 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, with Coupons corresponding to the Coupons, if any, appertaining to the surrendered Security, or, in case any such mutilated Security or Coupon has become or is about to become due and payable, the Corporation in its

37

discretion may, instead of issuing a new Security, with Coupons corresponding to the Coupons, if any, appertaining to the surrendered Security, pay such Security or Coupon.

If there shall be delivered to the Corporation and the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon 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 Corporation or the Trustee that such Security or Coupon has been acquired by a bona fide purchaser, the Corporation shall execute and upon Corporation Order the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the Security for which a destroyed, lost or stolen Coupon appertains (with all appurtenant Coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with Coupons corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the Corporation in its discretion may, instead of issuing a new Security, pay such Security, with Coupons corresponding to the Coupons, if any, appertaining to such mutilated, destroyed, lost or stolen Security or to the Security to which such mutilated, destroyed, lost or stolen Coupon appertains, pay such Security or Coupon; PROVIDED, HOWEVER, that payment of principal of (and premium, if any) and interest, if any, on Bearer Securities shall, except as otherwise provided in Section 10.2, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 3.1, any interest on Bearer Securities shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

Upon the issuance of any new Security under this Section, the Corporation 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 with its Coupons, if any, issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security or in exchange for a Security to which a mutilated, destroyed, lost or stolen Coupon appertains, shall constitute an original additional contractual obligation of the Corporation, whether or not the mutilated, destroyed, lost or stolen Security and its Coupons, if any, or the mutilated, destroyed, lost or stolen Coupon 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 and their Coupons, if any, duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, 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 or Coupons.

38

Section 3.7 PAYMENT OF PRINCIPAL AND INTEREST; INTEREST RIGHTS PRESERVED; OPTIONAL INTEREST RESET.

(a) Unless otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, interest, if any, on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Corporation maintained for such purpose pursuant to Section 10.2; PROVIDED, HOWEVER, that each installment of the principal of (and premium, if any, on) and interest, if any, on any Registered Security may at the Corporation's option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 3.9, to the address of such Person as it appears on the Security Register or (ii) wire transfer to an account located in the United States maintained by the payee (with wire transfer instructions provided to the Trustee not less than 15 days prior to payment of interest by wire transfer); PROVIDED FURTHER, that principal paid in relation to any Security redeemed at the option of the Corporation pursuant to Article Eleven, or paid at Maturity, shall be paid to the holder of such Security only upon presentation and surrender of such Security to such office or agency referred to in this Section 3.7(a).

Unless otherwise provided as contemplated by Section 3.1 with respect to the Securities of any series, payment of interest, if any, may be made, in the case of a Bearer Security, by transfer to an account located outside the United States maintained by the payee.

Unless otherwise provided as contemplated by Section 3.1, every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to each of Euroclear and Clearstream with respect to that portion of such permanent global Security held for its account by the Common Depositary, for the purpose of permitting each of Euroclear and Clearstream to credit the interest, if any, received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date 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 and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities of such series (such defaulted interest and, if applicable, interest thereon herein collectively called "DEFAULTED INTEREST") may be paid by the Corporation, at its election in each case, as provided in clause (1) or (2) below:

(1) The Corporation may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered 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 Corporation shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and at the same time the Corporation shall deposit with the Trustee an amount of money in the Currency in which the Securities of such series are payable

39

(except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) 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 on or 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 Corporation of such Special Record Date and, in the name and at the expense of the Corporation, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided in Section 1.6, 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 given, such Defaulted Interest shall be paid to the Persons in whose name the Registered 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 Corporation may make payment of any Defaulted Interest on the Registered 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 Corporation to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

(b) The provisions of this Section 3.7(b) may be made applicable to any series of Securities pursuant to Section 3.1 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.1). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series may be reset by the Corporation on the date or dates specified on the face of such Security (each an "OPTIONAL RESET DATE"). The Corporation may exercise such option with respect to such Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date for such Security, which notice shall specify the information to be included in the Reset Notice (as defined). Not later than 40 days prior to each Optional Reset Date, the Trustee shall transmit, in the manner provided for in
Section 1.6, to the Holder of any such Security a notice (the "RESET NOTICE") indicating whether the Corporation has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity of such Security (each such period a "SUBSEQUENT INTEREST PERIOD"), including the date or dates on which, or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period.

Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Corporation may, at its option, revoke the interest rate (or the spread or spread

40

multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or a spread or spread multiplier used to calculate such interest rate, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 1.6, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable).

The Holder of any such Security will have the option to elect repayment by the Corporation of the principal of such Security on each Optional Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date.

Subject to the foregoing provisions of this Section and
Section 3.5, 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 3.8 OPTIONAL EXTENSION OF STATED MATURITY.

The provisions of this Section 3.8 may be made applicable to any series of Securities pursuant to Section 3.1 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.1). The Stated Maturity of any Security of such series may be extended at the option of the Corporation for the period or periods specified on the face of such Security (each an "EXTENSION PERIOD") up to but not beyond the date set forth on the face of such Security. The Corporation may exercise such option with respect to any Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such option (the "ORIGINAL STATED MATURITY"). If the Corporation exercises such option, the Trustee shall transmit, in the manner provided for in Section 1.6, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the "EXTENSION NOTICE") indicating (i) the election of the Corporation to extend the Stated Maturity,
(ii) the new Stated Maturity, (iii) the interest rate, if any, applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee's transmittal of the Extension Notice, the Stated Maturity of such Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Extension Notice.

41

Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Corporation may, at its option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 1.6, notice of such higher interest rate to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate.

If the Corporation extends the Stated Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Corporation on the Original Stated Maturity at a price equal to the principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Corporation has extended the Maturity thereof, the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment until the close of business on the tenth day before the Original Stated Maturity.

Section 3.9 PERSONS DEEMED OWNERS.

Prior to due presentment of a Registered Security for registration of transfer, the Corporation, the Trustee and any agent of any of the foregoing may treat the Person in whose name such Registered Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 3.5 and 3.7) interest, if any, on such Registered Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Corporation, the Trustee or any agent of any of the foregoing shall be affected by notice to the contrary.

Title to any Bearer Security and any Coupons appertaining thereto shall pass by delivery. The Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the bearer of any Bearer Security and the bearer of any Coupon as the absolute owner of such Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Security or Coupons be overdue, and none of the Corporation, the Trustee or any agent of the Corporation or the Trustee shall be affected by notice to the contrary.

The Depositary for Securities may be treated by the Corporation, the Trustee, and any agent of the Corporation or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Corporation, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent the Corporation, the Trustee, or any agent of any of the foregoing from giving effect to any written certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such global Security or impair, as between such depositary and owners of

42

beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such global Security.

Section 3.10 CANCELLATION.

All Securities and Coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against any current or future sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities and Coupons so delivered to the Trustee shall be promptly cancelled by it. The Corporation may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Corporation 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 Corporation has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. If the Corporation shall so acquire any of the Securities, however, then, unless provided otherwise in an Officers' Certificate or a supplemental indenture relating to a series of Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. 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 by the Trustee in accordance with its customary procedures and certification of their disposal delivered to the Corporation unless by Corporation Order the Corporation shall direct that cancelled Securities be returned to it.

Section 3.11 COMPUTATION OF INTEREST.

Except as otherwise specified as contemplated by Section 3.1 with respect to any Securities, interest, if any, on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. For the purposes only of the disclosure required by the INTEREST ACT (Canada), and without affecting the amount of interest payable to any Holder or the calculation of interest on any Securities, if any rate of interest on any Securities is calculated on the basis of a deemed year which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for the purposes of the INTEREST ACT (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in such deemed year. Notwithstanding the foregoing, and for the purposes only of disclosure required by the INTEREST ACT (Canada), and without affecting the amount of interest payable to any Holder or the calculation of interest on any Securities, whenever interest to be paid under a Security is to be calculated on the basis of a year of 360 days consisting of twelve 30-day months, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent during any particular period is the rate so determined multiplied by a fraction of which:

(a) the numerator is the product of:

(i) the actual number of days in the calendar year in which the same is to be ascertained, and

43

(ii) the sum of (A) the product of (x) 30 and (y) the number of complete months elapsed in the relevant period and (B) the number of days elapsed in any incomplete month in the relevant period, and

(b) the denominator is the product of (i) 360 and (ii) the number of days in the relevant period.

Section 3.12 CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF SECURITIES.

(a) With respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or the Holders of which have not made the election provided for in paragraph (b) below, and with respect to Bearer Securities of any series except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and interest, if any, on any Registered or Bearer Security of such series will be made in the Currency in which such Registered or Bearer Security, as the case may be, is payable. The provisions of this Section 3.12 may be modified or superseded with respect to any Securities pursuant to Section 3.1.

(b) It may be provided pursuant to Section 3.1 with respect to Registered Securities of any series that Holders shall have the option, subject to paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered Securities in any of the Currencies which may be designated for such election by delivering to the Trustee a written election with signature guarantees and in the applicable form established pursuant to Section 3.1, not later than the close of business on the Election Date immediately preceding the applicable payment date. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustee (but any such change must be made not later than the close of business on the Election Date immediately preceding the next payment date to be effective for the payment to be made on such payment date and no such change of election may be made with respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has occurred or with respect to which the Corporation has deposited funds pursuant to Article Four or Fourteen or with respect to which a notice of redemption has been given by the Corporation or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Registered Security who shall not have delivered any such election to the Trustee not later than the close of business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant Currency as provided in Section 3.12(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Registered Securities for which Holders have made such written election.

(c) Unless otherwise specified pursuant to Section 3.1, if the election referred to in paragraph (b) above has been provided for pursuant to
Section 3.1, then, unless otherwise specified pursuant to Section 3.1, not later than the fourth Business Day after the Election Date for each payment date for Registered Securities of any series, the Exchange Rate Agent will deliver to the Corporation a written notice specifying, in the Currency in which Registered Securities of such series are payable, the respective aggregate amounts of principal of (and

44

premium, if any) and interest, if any, on the Registered Securities to be paid on such payment date, specifying the amounts in such Currency so payable in respect of the Registered Securities as to which the Holders of Registered Securities of such series shall have elected to be paid in another Currency as provided in paragraph (b) above. If the election referred to in paragraph (b) above has been provided for pursuant to Section 3.1 and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 3.1, on the second Business Day preceding such payment date the Corporation will deliver to the Trustee for such series of Registered Securities an Exchange Rate Officers' Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Unless otherwise specified pursuant to Section 3.1, the Dollar or Foreign Currency amount receivable by Holders of Registered Securities who have elected payment in a Currency as provided in paragraph (b) above shall be determined by the Corporation on the basis of the applicable Market Exchange Rate in effect on the third Business Day (the "VALUATION DATE") immediately preceding each payment date, and such determination shall be conclusive and binding for all purposes, absent manifest error.

(d) If a Conversion Event occurs with respect to a Foreign Currency in which any of the Securities are denominated or payable other than pursuant to an election provided for pursuant to paragraph (b) above, then with respect to each date for the payment of principal of (and premium, if any) and interest, if any, on the applicable Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the "CONVERSION DATE"), the Dollar shall be the Currency of payment for use on each such payment date. Unless otherwise specified pursuant to
Section 3.1, the Dollar amount to be paid by the Corporation to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

(e) Unless otherwise specified pursuant to Section 3.1, if the Holder of a Registered Security denominated in any Currency shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment in Dollars as provided in paragraph (d) above.

(f) The "Dollar Equivalent of the Foreign Currency" shall be determined by the Exchange Rate Agent and shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion Date.

(g) The "Dollar Equivalent of the Currency Unit" shall be determined by the Exchange Rate Agent and subject to the provisions of paragraph
(h) below shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency into Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date with respect to each payment.

45

(h) For purposes of this Section 3.12 the following terms shall have the following meanings:

A "Component Currency" shall mean any Currency which, on the Conversion Date, was a component currency of the relevant currency unit.

A "Specified Amount" of a Component Currency shall mean the number of units of such Component Currency or fractions thereof which were represented in the relevant currency unit, on the Conversion Date. If after the Conversion Date the official unit of any Component Currency is altered by way of combination or subdivision, the Specified Amount of such Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such Component Currencies shall be replaced by an amount in such single Currency equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed in such single Currency, and such amount shall thereafter be a Specified Amount and such single Currency shall thereafter be a Component Currency. If after the Conversion Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced by amounts of such two or more currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date of such replacement equal to the Dollar Equivalent value of the Specified Amount of such former Component Currency at the Market Exchange Rate immediately before such division and such amounts shall thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, a Conversion Event (other than any event referred to above in this definition of "Specified Amount") occurs with respect to any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion Date of such Component Currency.

"Election Date" shall mean the date for any series of Registered Securities as specified pursuant to clause (15) of Section 3.1 by which the written election referred to in paragraph (b) above may be made.

All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Corporation, the Trustee and all Holders of such Securities denominated or payable in the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Corporation and the Trustee of any such decision or determination.

In the event that the Corporation determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Corporation will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 1.6 to the affected Holders)

46

specifying the Conversion Date. In the event the Corporation so determines that a Conversion Event has occurred with respect to any currency unit in which Securities are denominated or payable, the Corporation will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in
Section 1.6 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion Date. In the event the Corporation determines in good faith that any subsequent change in any Component Currency as set forth in the definition of Specified Amount above has occurred, the Corporation will similarly give written notice to the Trustee and the Exchange Rate Agent.

The Trustee shall be fully justified and protected in relying and acting upon information received by it from the Corporation and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Corporation or the Exchange Rate Agent.

Section 3.13 APPOINTMENT AND RESIGNATION OF SUCCESSOR EXCHANGE RATE AGENT.

(a) Unless otherwise specified pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Corporation will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. The Corporation will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 3.1 for the purpose of determining the applicable rate of exchange and, if applicable, for the purpose of converting the issued Currency into the applicable payment Currency for the payment of principal (and premium, if any) and interest, if any, pursuant to Section 3.12.

(b) The Corporation shall have the right to remove and replace from time to time the Exchange Rate Agent for any series of Securities. No resignation or removal of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become effective until the acceptance of appointment by the successor Exchange Rate Agent as evidenced by a written instrument delivered to the Corporation and the Trustee.

(c) If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent for any cause with respect to the Securities of one or more series, the Corporation, by or pursuant to a Board Resolution, shall promptly appoint a successor Exchange Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series and that, unless otherwise specified pursuant to Section 3.1, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are originally issued by the Corporation on the same date and that are initially denominated and/or payable in the same Currency).

Section 4.2 APPLICATION OF TRUST MONEY.

Subject to the provisions of the last paragraph of Section 10.3, all money deposited with the Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Corporation acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

In addition to the events set forth above, the Corporation may by indenture supplemental hereto, executed and delivered pursuant to the provisions of Article 9, create further Events of Default.

Section 5.2 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

If an Event of Default described in Section 5.1 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 affected series may, subject to subordination provisions, if any, declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of such affected series) of all of the Securities of that series and all interest thereon to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable.

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

(1) the Corporation has paid or deposited with the Trustee a sum sufficient to pay in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(4) and 3.12(e)),

(A) all overdue interest, if any, on all Outstanding Securities of that series (or of all series, as the case may be) and any related Coupons,

(B) all unpaid principal of (and premium, if any)
any Outstanding Securities of that series (or of all series, as the case may be) which has become due otherwise than by such declaration of acceleration, and interest on such unpaid principal at the rate or rates prescribed therefor in such Securities,

51

(C) to the extent lawful, interest on overdue interest, if any, at the rate or rates prescribed therefor in such Securities, and

(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

(2) all Events of Default with respect to Securities of that series (or of all series, as the case may be), other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

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

Section 5.3 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

The Corporation covenants that if:

(1) default is made in the payment of any installment of interest on any Security, or any related Coupon when such interest becomes due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

then the Corporation will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Securities and Coupons, the whole amount then due and payable on such Securities and Coupons for principal (and premium, if any) and interest, if any, and, to the extent lawful, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Corporation fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Corporation or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Corporation or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series (or of all series, as the case may be) 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 (or of all series, as the case may be) by such appropriate judicial proceedings as the Trustee shall deem most

52

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.

Section 5.4 TRUSTEE MAY FILE PROOFS OF CLAIM.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Corporation or any other obligor upon the Securities or the property of the Corporation or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Corporation for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i) to file and prove a claim for the whole amount of principal (and premium, if any), or such portion of the principal amount of any series of Original Issue Discount Securities or Indexed Securities as may be specified in the terms of such series, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(ii) 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 the Trustee under Section 6.6.

Nothing herein contained 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.

Section 5.5 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

All rights of action and claims under this Indenture or the Securities or Coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or Coupons 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

53

benefit of the Holders of the Securities and Coupons in respect of which such judgment has been recovered.

Section 5.6 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 premium, if any) or interest, if any, upon presentation of the applicable Securities or Coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

(i) FIRST: To the payment of all amounts due the Trustee under Section 6.6;

(ii) SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest, if any, on the Securities and Coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities and Coupons for principal (and premium, if any) and interest, if any, respectively; and

(iii) THIRD: The balance, if any, to the Person or Persons entitled thereto.

Section 5.7 LIMITATION ON SUITS.

No Holder of any Security of any series or any related Coupons shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the Securities of any series, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of all series affected by such Event of Default (determined as provided in Section 5.2), shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with, such request;

(4) the Trustee for 60 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 60-day period by the Holders of a majority or more in principal amount of the Outstanding Securities of all series affected by such Event of Default (determined as provided in Section 5.2);

54

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 Holders of Outstanding Securities of any such affected series, or to obtain or to seek to obtain priority or preference over any other of 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 Holders of Outstanding Securities of all such affected series.

Section 5.8 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, as provided herein (including, if applicable, Article Fourteen) and in such Security, of the principal of (and premium, if any) and (subject to Section 3.7) interest, if any, on, such Security or payment of such Coupon on the respective Stated Maturities expressed in such Security or Coupons (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 5.9 RESTORATION OF RIGHTS AND REMEDIES.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Corporation, the Trustee and the Holders of Securities and Coupons shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 5.10 RIGHTS AND REMEDIES CUMULATIVE.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or Coupons 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 5.11 DELAY OR OMISSION NOT WAIVER.

No delay or omission of the Trustee or of any Holder of any Security or Coupon 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.

55

Section 5.12 CONTROL BY HOLDERS.

The Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected by an Event of Default (determined as provided in Section 5.2 and as one class) 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 Outstanding Securities of such affected series, provided in each case

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

Subject to Section 5.2, the Holders of not less than a majority in principal amount of the Outstanding Securities of all affected series with respect to which a Default shall have occurred and be continuing may on behalf of the Holders of all the Outstanding Securities of such affected series waive any past Default, and its consequences, except a Default

(1) in respect of the payment of the principal of (or premium, if any) or interest, if any, on any Security or any related Coupon or the payment of Additional Amounts, 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 affected series.

Upon any such waiver, any 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 Event of Default or impair any right consequent thereon.

Section 5.14 WAIVER OF STAY OR EXTENSION LAWS.

The Corporation 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 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 Corporation (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

56

granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 6.

THE TRUSTEE

Within 30 days after the occurrence of any Default hereunder with respect to the Securities of any series, the Trustee shall transmit in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, notice of such default hereunder known to the Trustee, unless such Default shall have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a Default in the payment of the principal of (or premium, if any) or interest, if any, on any Security of such series or in the payment of any sinking fund installment with respect to Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series and any related Coupons; and PROVIDED FURTHER that in the case of any Default of the character specified in Section 5.1(3) with respect to Securities of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Corporation, 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 which (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 Corporation or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee, unless contemplated otherwise by such supplemental indenture, 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. Whenever there is a successor Trustee with respect to one or more (but less than all) series of securities issued pursuant to this Indenture, the terms "Indenture" and "Securities"

62

shall have the meanings specified in the provisos to the respective definitions of those terms in Section 1.1 which contemplate such situation.

(c) Upon request of any such successor Trustee, the Corporation shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

(d) 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 6.10 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, 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 or consolidation 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. In case any of the Securities shall not have been authenticated by such predecessor Trustee, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee; PROVIDED, HOWEVER, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 6.11 APPOINTMENT OF AUTHENTICATING AGENT.

At any time when any of the Securities remain Outstanding, 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 and the Trustee shall give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.6. 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. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Corporation. 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 Corporation and shall at all times be a

63

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 $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation 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 corporation 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, it 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 consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, 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 Corporation. 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 Corporation. 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 which shall be acceptable to the Corporation and shall give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.6. 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 Corporation 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 alternate certificate of authentication in the following form:

Dated: ________________________

The Corporation covenants and agrees for the benefit of the Holders of each series of Securities and any related Coupons that it will duly and punctually pay or cause to be paid the principal of (and premium, if any) and interest, if any (including, in the case of a Default or an Event of Default, interest at the rate specified therein on the amount in Default to the extent lawful), on the Securities of that series in accordance with the terms of the Securities, any Coupons appertaining thereto and this Indenture. Unless otherwise specified as contemplated by Section 3.1 with respect to any series of Securities, any interest installments due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several Coupons for such interest installments as are evidenced thereby as they severally mature.

Section 10.2 MAINTENANCE OF OFFICE OR AGENCY.

If the Securities of a series are issuable only as Registered Securities, the Corporation will maintain or cause to be maintained 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, where Securities of that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable and where notices and demands to or upon the Corporation in respect of the Securities of that series and this Indenture may be served.

If Securities of a series are issuable as Bearer Securities, the Corporation will maintain an office or agency outside the United States where any Bearer Securities of that series

72

and related Coupons may be presented or surrendered for payment, where Bearer Securities of that series may be, surrendered for exchange, where Bearer Securities of that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable, where notices and demands to or upon the Corporation in respect of the Bearer Securities of that series and this Indenture may be served and where Bearer Securities of that series and related Coupons may be presented or surrendered for payment; PROVIDED, HOWEVER, that, if the Bearer Securities of that series are listed on any stock exchange located outside the United States and such stock exchange shall so require, the Corporation will maintain a Paying Agent for the Securities of that series in any required city located outside the United States so long as the Bearer Securities of that series are listed on such exchange.

The Corporation will give prompt written notice to the Trustee of the location, and any change in the location, of any such office or agency. If at any time the Corporation 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 the Corporate Trust Office of the Trustee, except that Bearer Securities of any series and the related Coupons may be presented and surrendered for payment at the offices specified in the Security, and the Corporation hereby appoints the same as its agent to receive such respective presentations, surrenders, notices and demands.

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, no payment of principal, premium or interest on Bearer Securities shall be made at any office or agency of the Corporation in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States; PROVIDED, HOWEVER, that, if the Securities of a series are payable in Dollars, payment of principal of (and premium, if any) and interest, if any, on any Bearer Security shall be made at the office of the Corporation's Paying Agent in The City of New York, if (but only if) payment in Dollars of the full amount of such principal, premium or interest, as the case may be, at all offices or agencies outside the United States maintained for such purpose by the Corporation in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions.

The Corporation 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 any such designation; PROVIDED, HOWEVER, that no such designation or rescission shall in any manner relieve the Corporation of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Corporation 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. Unless otherwise specified with respect to any Securities as contemplated by Section 3.1 with respect to a series of Securities, the Corporation hereby designates as a Place of Payment for each series of Securities the Corporate Trust/Global Finance Unit of the Trustee in New York, New York, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in the Borough of Manhattan, The City of New York and as its agent to receive all such presentations, surrenders, notices and demands.

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or

73

(ii) may be payable in a Foreign Currency, or so long as it is required under any other provision hereunder, then the Corporation will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent.

Section 10.3 MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

If the Corporation shall at any time act as its own Paying Agent with respect to any series of Securities and any related Coupons, it will, on or before each due date of the principal of (or premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal of (or premium, if any) or interest, if any, on Securities of such series 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 Corporation shall have one or more Paying Agents for any series of Securities and any related Coupons, it will, prior to 10:00 am (local time at the place of payment) on each due date of the principal of (or premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the principal (or premium, if any) or interest, if any, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Corporation will promptly notify the Trustee of its action or failure so to act.

The Corporation will cause each Paying Agent (other than the Trustee) for any series of Securities 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) hold all sums held by it for the payment of the principal of (and premium, if any) and interest, if any, on Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee notice of any default by the Corporation (or any other obligor upon the Securities of such series) in the making of any payment of principal of (or premium, if any) or interest, if any, on the Securities of such series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Corporation may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Corporation Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Corporation or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which sums were

74

held by the Corporation or such Paying Agent; 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 sums.

Except as provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or then held by the Corporation, in trust for the payment of the principal of (or premium, if any) or interest, if any, on any Security of any series, or any Coupon appertaining thereto, and remaining unclaimed for two years (or such shorter period as may be specified in the applicable abandoned property statutes) after such principal, premium or interest has become due and payable shall be paid to the Corporation, or the Corporation (if any money is then held by the Corporation) shall be discharged from such trust; and the Holder of such Security or Coupon shall thereafter, as an unsecured general creditor, look only to the Corporation for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Corporation as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the written direction and at the expense of the Corporation cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Corporation.

Section 10.4 STATEMENT AS TO COMPLIANCE.

The Corporation will deliver to the Trustee, within 140 days after the end of each fiscal year, a certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of whether the Corporation is in compliance with all conditions and covenants under this Indenture and, if not in such compliance, specifying all such known defaults. For purposes of this Section 10.4, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

Section 10.5 ADDITIONAL AMOUNTS.

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, all payments made by the Corporation under or with respect to the Securities of any series will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (hereinafter "TAXES"), unless the Corporation is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Corporation is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Securities, the Corporation will pay such additional amounts ("ADDITIONAL AMOUNTS") as may be necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction (and after deducting Taxes on such Additional Amounts) will not be less than the amount the Holder would have received if

75

such Taxes had not been withheld or deducted; PROVIDED that no Additional Amounts will be payable:

(1) to any Person in respect of whom such Taxes are required to be withheld or deducted as a result of such Person not dealing at arm's length with the Corporation (within the meaning of the INCOME TAX ACT (Canada));

(2) to any Person by reason of such Person being connected with Canada (otherwise than merely by holding or ownership of any series of Securities or receiving any payments or exercising any rights thereunder), including without limitation a non-resident insurer who carries on an insurance business in Canada and in a country other than Canada;

(3) for or on account of any Taxes which would not have been so imposed but for (i) the presentation by the Holder of such Security or Coupon for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later or (ii) the Holder's failure to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from or a reduction in the rate of deduction or withholding of, any such taxes, assessment or charge;

(4) for or on account of any estate, inheritance, gift, sales, transfer, personal property tax or any similar tax, assessment or other governmental charge;

(5) for or on account of any Taxes required to be withheld by any Paying Agent from any payment to a Person in respect of any Security, if such payment can be made to such Person without such withholding by at least one other Paying Agent the identity of which is provided to such Person;

(6) for or on account of any Taxes which are payable otherwise than by withholding from a payment in respect of such Security; or

(7) for any combination of items (1), (2), (3), (4), (5) and (6); nor will Additional Amounts be paid with respect to any payment on a Security to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to payment of the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Security.

At least 10 days prior to each date on which any payment under or with respect to the Securities is due and payable, if the Corporation will be obligated to pay Additional Amounts with respect to such payment, the Corporation will deliver to the Trustee an Officers' Certificate stating the fact that such Additional Amounts will be payable, the amounts so payable and will

76

set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date.

The Corporation will furnish to the Holders of the Securities, within 30 days after the date the payment of any Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by the Corporation.

Whenever in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), Redemption Price, interest or any other amount payable under or with respect to any Security such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made (if applicable).

The obligations of the Corporation under this Section 10.5 shall survive the termination of the Indenture.

Section 10.6 PAYMENT OF TAXES AND OTHER CLAIMS.

The Corporation will from time to time pay or discharge or cause to be paid or discharged all taxes, rates, levies, assessments, ordinary or extraordinary, government fees or dues lawfully levied, assessed or imposed upon or in respect of its property or any part thereof or upon the income and profits of the Corporation as and when the same become due and payable, and it will exhibit or cause to be exhibited to the Trustee, when requested, the receipts and vouchers establishing such payment and will duly observe and conform to all valid requirements of any governmental authority relative to any of the property or rights of the Corporation and all covenants, terms and conditions upon or under which any such property or rights are held; provided, however, that the Corporation shall have the right to contest by legal proceedings any such taxes, rates, levies, assessments, government fees or dues, and upon such contest, may delay or defer payment or discharge thereof.

Section 10.7 MAINTENANCE OF PROPERTIES.

The Corporation will cause all its properties to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Corporation may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent or restrict the sale, abandonment or other disposition of any of such properties if such action is, in the judgment of the Corporation desirable in the conduct of the business of the Corporation.

Subject to Article Eight, the Corporation will at all times
(i) maintain and keep in full force and effect its corporate existence and the rights (charter and statutory) and franchises

77

of the Corporation and (ii) carry on and conduct its businesses in a proper, efficient and business-like manner and in accordance with good business practice; PROVIDED, HOWEVER, that the Corporation shall not be required to preserve any such right or franchise if the Corporation shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Corporation and its Subsidiaries as a whole, as the case may be.

Section 10.9 MAINTENANCE OF BOOKS AND RECORDS.

The Corporation shall keep or cause to be kept proper books of record and account, in which full and correct entries shall be made of all financial transactions and the assets and business of the Corporation in accordance with Generally Accepted Accounting Principles.

Section 10.10 RESTRICTION OF SALES AND LEASEBACK TRANSACTIONS

The Corporation shall not, and shall not permit any Subsidiary to, enter into any sale and leaseback transaction unless the Corporation and its Subsidiaries comply with this restrictive covenant. A "sale and leaseback transaction" is an arrangement between the Corporation or any Subsidiary and a bank, insurance company or other lender or investor where the Corporation or any Subsidiary lease real or personal property which was or will be sold by the Corporation or any Subsidiary to that lender or investor. The Corporation can comply with this Section 10.10 if either (i) the sale and leaseback transaction is entered into prior to, concurrently with or within 270 days after the acquisition, the completion of construction (including any improvements on an existing property) or the commencement of commercial operations of the property or (ii) the Corporation or its Subsidiaries could otherwise grant a Security Interest on the property as permitted by the provisions of Section 10.12 hereof.

Section 10.11 INSURANCE.

The Corporation shall have in full force and effect such policies of insurance in such amounts issued by insurers of recognized standing covering the properties and operations of the Corporation as are customarily held by similar corporations engaged in the same or similar business in the localities where its properties and operations are located.

So long as any Securities remain Outstanding the Corporation and its Subsidiaries will not create, assume or otherwise have Outstanding any Security Interest, except for Permitted Encumbrances, on or over its or their respective assets (present or future) in respect of any Indebtedness of any person unless, in the Opinion of Counsel to the Corporation or the Trustee, the obligations of the Corporation in respect of all Securities then Outstanding shall be secured equally and ratably therewith (either by the same instrument or by other instrument).

Section 10.13 WAIVER OF CERTAIN COVENANTS.

The Corporation may, with respect to any series of Securities, omit in any particular instance to comply with any term, provision or condition which affects such series set

78

forth in Section 8.4 or Sections 10.6 to 10.8, Section 10.10 and Section 10.12, inclusive, or any covenants added to Article Ten pursuant to Section 3.1 in connection with Securities of such series, if before the time for such compliance the Holders of at least a majority in principal amount of all Outstanding Securities of any series, by Act of such Holders, waive such compliance in such instance 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 Corporation and the duties of the Trustee to Holders of Securities of such series in respect of any such term, provision or condition shall remain in full force and effect.

The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution.

In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Corporation shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction.

Section 11.3 SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

The Trustee shall promptly notify the Corporation and the Security Registrar (if other than the Corporation) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

79

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

Section 11.4 NOTICE OF REDEMPTION.

Except as otherwise specified as contemplated by Section 3.1, notice of redemption shall be given in the manner provided for in Section 1.6 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. Failure to give notice in the manner provided in Section 1.6 to the Holder of any Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

Any notice that is mailed to the Holder of any Securities in the manner provided in Section 1.6 shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

(5) that on the Redemption Date, the Redemption Price and accrued interest, if any, to the Redemption Date payable as provided in Section 11.6 will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(6) the Place or Places of Payment where such Securities, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any,

Section 10.3) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the Redemption Price of, and accrued interest, if any, on, all the Securities which are to be redeemed on that date.

Section 11.6 SECURITIES PAYABLE ON REDEMPTION DATE.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Corporation shall default in the payment of the Redemption Price and accrued interest, if any) such Securities shall, if the same were interest-bearing, cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Corporation at the Redemption Price, together with accrued interest, if any, to the Redemption Date; PROVIDED, HOWEVER, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.2) and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and surrender of Coupons for such interest; and PROVIDED FURTHER, that installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date or

81

Special Record Date, as the case may be, according to their terms and the provisions of Section 3.7.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Corporation and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; PROVIDED, HOWEVER, that interest represented by Coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in
Section 10.2) and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and surrender of those Coupons.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security,

Section 11.7 SECURITIES REDEEMED IN PART.

Any Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered at a Place of Payment therefor (with, if the Corporation or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Corporation and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing), and the Corporation shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

Section 11.8 TAX REDEMPTION.

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, the Securities of a series will be subject to redemption at any time, in whole but not in part, at a redemption price equal to the principal amount thereof together with accrued and unpaid interest to the date fixed for redemption, upon the giving of a notice as described below, if
(1) the Corporation determines that (a) as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of Canada or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the date specified pursuant to Section 3.1, if any date is so specified, the Corporation has or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts pursuant to Section 10.5 or (b) on or after the date specified pursuant to Section 3.1,

82

any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in, Canada or any political subdivision or taxing authority thereof or therein, including any of those actions specified in (a) above, whether or not such action was taken or decision was rendered with respect to the Corporation, or any change, amendment, application or interpretation shall be officially proposed, which, in any such case, in the Opinion of Counsel to the Corporation of recognized standing, will result in the Corporation becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any Security of such series and (2) in any such case, the Corporation in its business judgment determines that such obligation cannot be avoided by the use of reasonable measures available to the Corporation; PROVIDED HOWEVER, that (i) no such notice of redemption may be given earlier than 60 or later than 30 days prior to the earliest date on which the Corporation would be obligated to pay such Additional Amounts were a payment in respect of the Securities then due, and (ii) at the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect.

Subject to Section 12.3, in lieu of making all or any part of any mandatory sinking fund payment with respect to any Securities of a series in cash, the Corporation may at its option (1) deliver to the Trustee Outstanding Securities of a series (other than any previously called for redemption) theretofore purchased or otherwise acquired by the Corporation together in the case of Bearer Securities of such series with all unmatured Coupons appertaining thereto, and/or (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustee by the Corporation for Securities of such series which have been redeemed either at the election of the Corporation pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of the same series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; PROVIDED, HOWEVER, that such

83

Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

Section 12.3 REDEMPTION OF SECURITIES FOR SINKING FUND.

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Corporation will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 12.2 (which Securities will, if not previously delivered, accompany such certificate) and whether the Corporation intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Corporation shall be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Corporation to deliver such certificate, the sinking fund payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without, with respect to such payment date, the option to deliver or credit Securities as provided in
Section 12.2 and without the right to make any optional sinking fund payment, if any, with respect to such series.

Not more than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Corporation in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.6 and 11.7.

Prior to any sinking fund payment date, the Corporation shall pay to the Trustee or a Paying Agent (or, if the Corporation is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) in cash a sum equal to any interest that will accrue to the date fixed for redemption of Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 12.3.

Notwithstanding the foregoing, with respect to a sinking fund for any series of Securities, if at any time the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not exceed in the aggregate $100,000, the Trustee, unless requested by the Corporation, shall not give the next succeeding notice of the redemption of Securities of such series through the operation of the sinking fund. Any such unused balance of moneys deposited in such sinking fund shall be added to the sinking fund payment for such series to be made in cash on the next succeeding sinking fund payment date or,

84

at the request of the Corporation, shall be applied at any time or from time to time to the purchase of Securities of such series, by public or private purchase, in the open market or otherwise, at a purchase price for such Securities (excluding accrued interest and brokerage commissions, for which the Trustee or any Paying Agent will be reimbursed by the Corporation) not in excess of the principal amount thereof.

ARTICLE 13.

REPAYMENT AT OPTION OF HOLDERS

Section 13.1 APPLICABILITY OF ARTICLE.

Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified as contemplated by
Section 3.1 for Securities of any series) in accordance with this Article.

Section 13.2 REPAYMENT OF SECURITIES.

Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Corporation covenants that on or before the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Corporation is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of and (except if the Repayment Date shall be an Interest Payment Date) accrued interest, if any, on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

Section 13.3 EXERCISE OF OPTION.

Securities of any series subject to repayment at the option of the Holders thereof will contain an "Option to Elect Repayment" form on the reverse of such Securities. To be repaid at the option of the Holder, any Security so providing for such repayment, with the "Option to Elect Repayment" form on the reverse of such Security duly completed by the Holder (or by the Holder's attorney duly authorized in writing), must be received by the Corporation at the Place of Payment therefor specified in the terms of such Security (or at such other place or places or which the Corporation shall from time to time notify the Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repayment Date. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such Security surrendered

85

that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Corporation.

Section 13.4 WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND PAYABLE.

If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Corporation on the Repayment Date therein specified, and on and after such Repayment Date (unless the Corporation shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be repaid, except to the extent provided below shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, the principal amount of such Security so to be repaid shall be paid by the Corporation, together with accrued interest, if any, to the Repayment Date; PROVIDED, HOWEVER, that Coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.2) and, unless otherwise specified pursuant to Section 3.1, only upon presentation and surrender of such Coupons; and PROVIDED FURTHER that, in the case of Registered Securities, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7.

If the principal amount of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security.

If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant Coupons maturing after the Repayment Date, such Security may be paid after deducting from the amount payable therefor as provided in Section 13.2 an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Corporation and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; PROVIDED, HOWEVER, that interest represented by Coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in
Section 10.2) and, unless

86

otherwise specified as contemplated by Section 3.1, only upon presentation and surrender of those Coupons.

Section 13.5 SECURITIES REPAID IN PART.

Upon surrender of any Registered Security which is to be repaid in part only, the Corporation shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Corporation, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid.

ARTICLE 14.

DEFEASANCE AND COVENANT DEFEASANCE

Section 14.1 OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, the provisions of this Article Fourteen shall apply to each series of Securities, and the Corporation may, at its option, effect defeasance of the Securities of or within a series under Section 14.2, or covenant defeasance of or within a series under Section 14.3 in accordance with the terms of such Securities and in accordance with this Article.

Section 14.2 DEFEASANCE AND DISCHARGE.

Upon the exercise by the Corporation of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in Section 14.4 are satisfied (hereinafter, "DEFEASANCE"). For this purpose, such defeasance means that the Corporation shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities which shall thereafter be deemed to be "Outstanding" only for the purposes of
Section 14.5 and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all of its other obligations under such Securities, and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Corporation, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of holders of such Outstanding Securities to receive, solely from the trust fund described in
Section 14.4 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on such Securities when such payments are due, (B) the Corporation's obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.2, 10.3 and 10.5 and the Corporation's rights pursuant to Section 11.8, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Fourteen. Subject to compliance with this Article Fourteen, the Corporation may exercise its option under this Section 14.2 notwithstanding the prior exercise of the option under Section 14.3 with respect to such Securities and any related Coupons.

Section 14.3 COVENANT DEFEASANCE.

87

Upon the exercise by the Corporation of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be released from its obligations under Section 8.4 and Sections 10.6 through 10.8, 10.10 and 10.12, and, if specified pursuant to
Section 3.1, their obligations under any other covenant, with respect to such Outstanding Securities on and after the date the conditions set forth in Section 14.4 are satisfied (hereinafter, "COVENANT DEFEASANCE"), and such Securities shall thereafter be deemed not to be "Outstanding" for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences thereof) in connection with such covenants, but shall continue to be deemed "Outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Corporation may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 5.1(3) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

Section 14.4 CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

The following shall be the conditions to application of either
Section 14.2 or Section 14.3 to any Outstanding Securities of or within a series:

(1) The Corporation shall have irrevocably deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 6.7 who shall agree to comply with the provisions of this Article Fourteen applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) an amount (in such Currency in which such Securities are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal of and premium, if any, and interest, if any, under such Securities, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent chartered accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (1) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities on the Stated Maturity (or Redemption Date, if applicable) of such principal
(and premium, if any) or installment of interest, if any, and (ii) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities; PROVIDED that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to said payments with respect to such Securities. Before such a deposit, the Corporation may give to the Trustee, in accordance with Section 11.2 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in

88

accordance with the terms of the Securities of such series and Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(2) In the case of an election under Section 14.2, the Corporation shall have delivered to the Trustee an Opinion of Counsel of recognized standing in the United States stating that
(i) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(3) In the case of an election under Section 14.3, the Corporation shall have delivered to the Trustee an Opinion of Counsel of recognized standing in the United States to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

(4) Either the Corporation has delivered to the Trustee an Opinion of Counsel of recognized standing in Canada or a ruling from Canada Customs and Revenue Agency to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for Canadian federal, provincial or territorial income tax or other tax purposes as a result of such defeasance or covenant defeasance and will be subject to Canadian federal or provincial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case had such defeasance or covenant defeasance, as applicable, not occurred (and for the purposes of such opinion, such Canadian counsel shall assume that Holders of the Securities include Holders who are not resident in Canada).

(5) The Corporation is not an "insolvent person" within the meaning of the BANKRUPTCY AND INSOLVENCY ACT (Canada) on the date of such deposit or at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(6) No Event of Default or Default with respect to such Securities shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs (6) and (7) of Section 5.1 are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

89

(7) The Corporation has delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the Investment Company Act of 1940, as amended.

(8) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Corporation is a party or by which it is bound.

(9) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations in connection therewith pursuant to Section 3.1.

(10) The Corporation shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 14.2 or the covenant defeasance under
Section 14.3 (as the case may be) have been complied with.

Section 14.5 DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

Subject to the provisions of the last paragraph of Section 10.3, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 14.5, the "TRUSTEE") pursuant to Section 14.4 in respect of such Outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Corporation acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

Unless otherwise specified with respect to any Security pursuant to Section 3.1, if, after a deposit referred to in Section 14.4(1) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.12(b) or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 14.4(1) has been made in respect of such Security, or (b) a Conversion Event occurs as contemplated in Section 3.12(d) or 3.12(e) or by the terms of any Security in respect of which the deposit pursuant to
Section 14.4(1) has been made, the indebtedness represented by such Security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and interest, if any, on such Security as they become due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on the applicable Market Exchange Rate for such Currency in effect on the third Business Day prior to each payment date, except, with respect to a Conversion Event, for such Currency in effect (as nearly as feasible) at the time of the Conversion Event.

90

The Corporation shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 14.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities.

Anything in this Article Fourteen to the contrary notwithstanding, the Trustee shall deliver or pay to the Corporation from time to time upon a Corporation Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 14.4 which, in the opinion of a nationally recognized firm of independent chartered 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 an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article.

Section 14.6 REINSTATEMENT.

If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 14.5 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Corporation under this Indenture and such Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 14.2 or 14.3, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 14.5; PROVIDED, HOWEVER, that if the Corporation makes any payment of principal of (or premium, if any) or interest, if any, on any such Security following the reinstatement of its obligations, the Corporation shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

Ladies and Gentlemen:

TransAlta Corporation, a corporation organized under the laws of Canada (the "Company"), proposes to sell to the several underwriters named in Schedule I hereto (the "Underwriters"), for whom you (the "Representatives") are acting as representatives, U.S.$300,000,000 principal amount of its 6.750% Senior Notes due 2012 (the "Securities"), to be issued under an indenture (the "Indenture") to be dated as of June 25, 2002, between the Company and The Bank of New York, as trustee (the "Trustee"). To the extent there are no additional Underwriters listed on Schedule I other than you, the term Representatives as used herein shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires.

The Company has prepared and filed a preliminary short form base shelf prospectus, dated May 6, 2002, and a final short form base shelf prospectus, dated May 14, 2002, in respect of the Securities with the Alberta Securities Commission (the "Reviewing Authority"), and has been issued a preliminary receipt by the Reviewing Authority for such preliminary short form base shelf prospectus and a final receipt by the Reviewing Authority for such final short form base shelf prospectus (hereinafter called


2

the "Canadian Shelf Prospectus"). The Reviewing Authority is the principal regulator regulating the offering of the Securities. The term "Canadian Basic Prospectus" means the Canadian Shelf Prospectus at the time the Reviewing Authority issued a final receipt with respect thereto in accordance with the rules and procedures established under the securities laws, rules, regulations and published policy statements applicable in the Province of Alberta and the federal laws of Canada applicable therein (the "Alberta Securities Laws"), including National Instrument 44-101 Short Form Prospectus Distributions ("NI 44-101") and Companion Policy 44-101CP and National Instrument 44-102 Shelf Distributions and Companion Policy 44-102CP (collectively, the "Shelf Procedures").

The Company has also filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form F-10 (File No. 333-87762) providing for the registration of common shares, first preferred shares, debt securities and warrants, including the Securities, under the United States Securities Act of 1933, as amended (the "1933 Act"), and the rules and regulations of the Commission thereunder (the "1933 Act Regulations").

Such registration statement, as amended, including any exhibits and all documents incorporated therein by reference, as of the time it became effective, and in the event of any post-effective amendments filed prior to the execution of this Agreement, as of the date of the effectiveness of such amendment, is referred to herein as the "Registration Statement". The Canadian Basic Prospectus (with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the Commission) included in the Registration Statement shall be referred to herein as the "U.S. Basic Prospectus," and the U.S. Basic Prospectus, once it is filed together with the prospectus supplement relating to the offering of the Securities first filed with the Commission pursuant to General Instruction II.L. of Form F-10 following the execution of this Underwriting Agreement, including all documents incorporated therein by reference as of the date of this Underwriting Agreement, is referred to herein as the "U.S. Prospectus". A "preliminary prospectus" shall be deemed to refer to any prospectus which describes the Securities and the offering thereof and is used by the Underwriters prior to filing of the U.S. Prospectus or the Canadian Prospectus.

The Company has prepared and filed with the Commission an appointment of agent for service of process upon the Company on Form F-X in

conjunction with the filing of the Registration Statement (the "Form F-X"). The Company has also caused the Trustee to prepare and file with the Commission a Statement of Eligibility under the Trust Indenture Act of 1939, as amended (the "1939 Act") on Form T-1 (the "Form T-1").

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" (or other references of like import) in the Registration Statement, the U.S. Prospectus, the Canadian Prospectus or any preliminary prospectus shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference therein as of the date of such Registration Statement, U.S. Prospectus, Canadian Prospectus or any preliminary prospectus, as the case may be.

(e) The Company shall have furnished to the Representatives a certificate of the Company, signed by the two senior officers (one executive and one financial) of the Company acceptable to the Representatives, acting reasonably (on behalf of the Company and not in a personal capacity), dated the Closing Date, to the effect that:

(g) The Registration Statement shall have become effective under the 1933 Act prior to the Execution Time or at such later time or on such later date as the Representatives shall have agreed to in writing. The U.S. Prospectus shall have been filed in the manner and within the time period required by General Instruction II.L. of Form F-10; and no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted by the Commission and any request for additional information shall have been complied with.

(h) Ernst & Young LLP, Chartered Accountants, the independent chartered accountants of the Company, shall have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, (which may refer to letters previously delivered to one or more of the Representatives), dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, together with signed or reproduced copies of such letter for each of the Underwriters containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, the Canadian Prospectus and the U.S. Prospectus.

18

(j) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Company's debt securities by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the 1933 Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(k) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Latham & Watkins, United States counsel for the Company, at 885 Third Avenue, New York, New York 10022-4802, on the Closing Date.

7. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through Salomon Smith Barney Inc. on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the 1933 Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment


19

thereof, or in any preliminary prospectus, the Canadian Basic Prospectus, U.S. Basic Prospectus, Canadian Prospectus or U.S. Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, provided, further, that this indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter, or any person controlling such Underwriter, if a copy of the U.S. Prospectus or Canadian Prospectus was not sent or given by or on behalf of such Underwriter to such person at or prior to the written confirmation of the sale of such Securities to such person and that the U.S. Prospectus or the Canadian Prospectus (as so amended or supplemented, if applicable) would have corrected the defect giving rise to such loss, liability, claim, damage or expense. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement or the Canadian Prospectus, and each person who controls the Company within the meaning of either the 1933 Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party and to assume the defense thereof in any action for which


20

indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); PROVIDED, HOWEVER, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; PROVIDED, HOWEVER, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the


21

Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by each Underwriter shall be deemed to be equal to the total underwriting discounts and commissions received by such Underwriter, in each case as set forth on the cover page of the Canadian Prospectus and the U.S. Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the 1933 Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the 1933 Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. DEFAULT BY AN UNDERWRITER. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as


22

the Representatives shall determine in order that the required changes in the Registration Statement and the Canadian Prospectus and the U.S. Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. TERMINATION. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time
(i) trading in the Company's securities shall have been suspended by the Commission, the Reviewing Authority, or the Toronto Stock Exchange or the New York Stock Exchange, or trading in securities generally on the Toronto Stock Exchange or the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on either of such exchanges, (ii) a banking moratorium shall have been declared either by U.S. Federal, New York State or Canadian Federal authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or Canada of a national emergency or war, or other calamity or crisis the effect of which on U.S. and Canadian financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Canadian Prospectus and the U.S. Prospectus.

11. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. NOTICES. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to the Salomon Smith Barney Inc. General Counsel (fax no.:
(212) 816-7912) and confirmed to the General Counsel, Salomon Smith Barney Inc., at 388 Greenwich Street, New York, New York, 10013, Attention: General Counsel; or, if sent to the Company, will be mailed, delivered or telefaxed to TransAlta Corporation (403) 267-4764 and confirmed to it at 110-12th Avenue S.W., Calgary, Alberta, TOP 2M1 Canada, attention Marvin Waiand, Vice-President Finance and Treasurer, with a copy to Latham & Watkins, Attention: Robert A. Zuccaro, 885 Third Avenue, New York, New York 10022.

13. SUCCESSORS. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors,


23

employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. APPLICABLE LAW. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

15. COUNTERPARTS. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

The Company irrevocably (i) agrees that any legal suit, action or proceeding against the Company brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated thereby may be instituted in any New York Court, (ii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and

EXHIBIT A
Form of Latham & Watkins Opinion

1. The Indenture is the legally valid and binding agreement of the Company enforceable against it in accordance with its terms.

2. The Notes, when duly executed, issued and authenticated in accordance with the terms of the Indenture and delivered to and paid for by you in accordance with the terms of the Underwriting Agreement, will be the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

3. Each of the Underwriting Agreement, the Indenture and the Notes has been delivered by the Company, to the extent delivery thereof is governed by the laws of the State of New York.

4. The Indenture has been qualified under the Trust Indenture Act of 1939, as amended.

5. The Notes and Indenture conform in all material respects to the descriptions thereof in the Prospectus under the caption "Description of Notes," in each case insofar as such descriptions are summaries of legal matters.

6. The execution and delivery of the Underwriting Agreement and the Indenture and the issuance and sale of the Notes by the Company pursuant to the Underwriting Agreement on the date hereof do not (a) violate any U.S. federal or New York State statute, rule or regulation; (b) require any consents, approvals, authorizations, registrations, declarations or filings by the Company under any U.S. federal or New York State statute, rule or regulation, except such as have been obtained under the Act and such as may be required under state securities laws in connection with the purchase and distribution of the Notes by the Underwriters; or (c) violate any U.S. federal or New York State court or administrative orders, writs, judgments or decrees specifically directed to the Company that were identified to us by an officer of the Company as material to the Company.

7. The Registration Statement has become effective under the Act and to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. Any required filing of the Prospectus and the Prospectus Supplement pursuant to General Instruction II. L. of Form F-10 has been made in accordance with General Instruction II. L. of Form F-10.

8. The Registration Statement, as of the date it was declared effective, and the Prospectus, as of its date, complied as to form in all material respects with the requirements for registration statements on Form F-10 under the Act and the rules and


3

regulations of the Commission thereunder; it being understood, however, that we express no opinion with respect to the financial statements, schedules, other financial data or the Form T-1 included in, incorporated by reference in, or omitted from, the Registration Statement or the Prospectus; and the Form F-X filed with the Registration Statement, as of its date, complied as to form in all material respects with the requirements for an appointment of agent for service of process and undertaking on Form F-X under the Act and the rules and regulations of the Commission thereunder. In passing upon the compliance as to form of the Registration Statement, the Prospectus and the Form F-X, we have assumed that the statements made therein are correct and complete.

9. The Company is not, and after giving effect to the sale of the Notes in accordance with the Underwriting Agreement and the application of the proceeds as described in the Prospectus under the caption "Use of Proceeds," will not be an "investment company" within the meaning of the Investment Company Act of 1940, as amended.

10. Pursuant to Section 18 of the Underwriting Agreement and Section 1.13 of the Indenture, the Company has validly (a) submitted to the personal jurisdiction of any New York State or U.S. federal court located in the City of New York in connection with any suit or proceeding arising out of or related to the Notes, the Underwriting Agreement or the Indenture, (b) to the fullest extent permitted by law, waived any objection to the venue of a proceeding in any such court and (c) appointed CT Corporation as its initial authorized agent for the purpose described in Section 18 of the Underwriting Agreement and
Section 1.13 of the Indenture.

11.
