Each such Officers’ Certificate or Opinion of Counsel with respect to compliance with a covenant or condition provided for in this Indenture shall include:

(a) a statement that each individual signing such certificate or opinion has read and understands such covenant or condition and the definitions herein relating thereto;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

1.3 Form of Documents Delivered to Trustees

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Any certificate or opinion of an officer of the Corporation may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Corporation stating that the information with respect to such factual matters is in the possession of the Corporation, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

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

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. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustees and, where it is hereby expressly required, to the Corporation. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments 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 conclusive in favour of the Trustees and the Corporation, if made in the manner provided in this Section.

(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 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 Trustees deem sufficient.

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

(d) If the Corporation shall solicit from the Holders of Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Corporation may, at its option, by or pursuant to 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 TIA Section 316(c), 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 11 months after the record date.

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

1.5 Notices, Etc. to Trustees and Corporation

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

(a) the U.S. Trustee by the Canadian Trustee, any Holder or the Corporation shall be sufficient for every purpose hereunder if made, given, furnished or delivered, in writing to or with the U.S. Trustee at its Corporate Trust Office; or

(b) the Canadian Trustee by the U.S. Trustee, any Holder or the Corporation shall be sufficient for every purpose hereunder if made, given, furnished or delivered, in writing to or with the Canadian Trustee at its Corporate Trust Office; and

(c) the Corporation by either 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 and marked for the attention of the Secretary, or at any other address previously furnished in writing to the Trustees by the Corporation.

1.6 Notice to Holders; Waiver

Where this Indenture provides for notice of any event to Holders of Securities by the Corporation or either 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, 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 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 Securities. 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 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 satisfactory to the applicable Trustee shall be deemed to be sufficient giving of such notice for every purpose hereunder.

Any request, demand, authorization, direction, notice, consent or waiver 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 either Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

1.7 Effect of Headings and Table of Contents

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

1.8 Successors and Assigns

All covenants and agreements in this Indenture by the Corporation shall bind its successors and assigns, whether so expressed or not.

1.9 Severability Clause

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

1.10 Benefits of Indenture

Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

1.11 Governing Law

This Indenture and the Securities shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein. This Indenture is subject to the provisions of Trust Indenture Legislation and shall, to the extent applicable, be governed by such provisions.

1.12 Legal Holidays

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 interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date 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.

1.13 Entire Agreement

The Indenture constitutes the entire agreement between the Corporation, the Trustees and Holders. No implied covenant, agreement, representation or warranty shall be read into the Indenture against the Corporation, including any covenant, agreement, representation or warranty pertaining to the protection of the reasonable expectations of Holders. For purposes of any rights or remedies under Trust Indenture Legislation that Holders of Notes from time to time or the applicable Trustee may assert or employ, any act or omission of the Corporation that does not constitute a default in the performance, or breach, of any of its covenants or agreements in the Indenture shall be deemed conclusively to be fair and reasonable insofar as the interests of

Holders are concerned. For greater certainty, representations, warranties and statements made by or on behalf of the Corporation (whether orally or in writing) shall not give rise to, or form the basis of, any reasonable expectations of Holders for purposes of any rights or remedies under Trust Indenture Legislation that Holders from time to time or the applicable Trustee may assert or employ. The Indenture may not be supplemented, amended or modified, directly or indirectly, except by one or more indentures supplemental to the Indenture entered into pursuant to the applicable provisions thereof.

2.3 Securities Issuable in Global Form

If Securities of or within a series are specified to be issuable in global form, as contemplated by Section 3.1, then, notwithstanding clause (h) 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 either 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 such Trustee pursuant to Section 3.3 or Section 3.4. Subject to the provisions of Section 3.3 and, if applicable, Section 3.4, such 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 either 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 any premium and interest 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 Trustees and any agent of the Corporation and the Trustees shall treat the registered Holder of any global Security as the Holder of the Outstanding Securities represented thereby for all purposes.

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in any such indenture supplemental hereto. Not all Securities of any one series need be issued at the same time, and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series.

3.2 Denominations

All Securities shall be issuable in such denominations as shall be specified as contemplated by Section 3.1. Securities of any series denominated in U.S. Dollars, in the absence of any such provisions, shall be issuable in denominations of U.S.$1,000 and any integral multiple thereof.

3.3 Execution, Authentication, Delivery and Dating

The Securities shall be executed on behalf of the Corporation by its Chairman, its Chief Executive Officer or Chief Financial Officer. The signature of any of these officers on the Securities 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.

Securities 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 did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Securities of any series executed by the Corporation to one of the Trustees for authentication, together with a Corporation Order for the authentication and delivery of such Securities, and such Trustee, in accordance with the Corporation Order, shall authenticate and deliver such Securities. If not all the Securities of any series are to be issued at one time and if the supplemental indenture establishing such series shall so permit, such Corporation Order may set forth procedures acceptable to the applicable Trustee for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, maturity date, 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 applicable Trustee shall be entitled to receive, and (subject to Trust Indenture Legislation) shall be fully protected in acting and relying upon, an Opinion of Counsel stating:

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

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

(c) that such Securities, when completed by appropriate insertions and executed and delivered by the Corporation to one of the Trustees for authentication in accordance with this Indenture, authenticated and delivered by such 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 in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights, to general equitable principles and to such other qualifications as such counsel shall conclude do not materially affect the rights of Holders of such Securities; and

(d) that authentication and delivery of such Securities and the execution and delivery of the supplemental indenture, if any, by such Trustee will not violate the terms of the Indenture.

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 Officer’s 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.

A Trustee shall not be required to authenticate and deliver any such Securities if the issue of such Securities pursuant to this Indenture will affect such Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to such Trustee.

Each Security shall be dated the date of its issue.

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

3.4 Temporary Securities

Pending the preparation of definitive Securities of any series, the Corporation may execute, and upon Corporation Order one of the Trustees 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, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. In the case of Securities of any series, such temporary Securities may be in global form.

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 of such series, upon surrender of the temporary Securities of such series at the Corporate Trust Office for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Corporation shall execute and one of the Trustees shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of like tenor of the same series of authorized denominations. 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.

3.5 Registration, Registration of Transfer and Exchange

So long as required by Trust Indenture Legislation, the Corporation shall cause to be kept at its registered office in Ontario, or at the Corporate Trust Office in Canada an index and register (the “principal register”) of Holders of Securities and shall as soon as possible cause to be entered

therein the name (alphabetically arranged) of every person who becomes a Holder together with (i) the full name and address of every Holder, noting, where applicable, the Holder’s representative capacity, (ii) the date that each Holder is entered in the principal register, and whether the Holder acquired its Security by issue or transfer or otherwise and, if by transfer, from whom, (iii) the date that a person ceases to be a Holder, (iv) the principal amount of Securities held by the Holder, and the (v) particulars of the Securities held by the Holder. The Trustee shall initially be the principal securities registrar for the purpose of registering the transfer and exchange of Securities as provided herein; provided, however, that the Corporation may appoint from time to time one or more successor principal security registrars and may from time to time rescind any such appointment. If no longer required by Trust Indenture Legislation, the Corporation may appoint a Person other than the Corporation or a trust corporation in Canada as the principal securities registrar.

The Corporation may also cause to be maintained a branch register or branch registers (each a “branch register”) of Holders of Securities in accordance with Section 10.2 in the same manner and containing the same information with respect to each entry contained therein as contained in the principal register. A copy of every entry in any branch register shall, promptly after the entry is made, be transmitted to the principal registrar. Unless otherwise specified pursuant to Section 3.1, the U.S. Trustee is hereby initially appointed as a branch registrar for the purpose of maintaining a branch register with respect to the Securities of each series at its Corporate Trust Office; provided, however, that the Corporation may from time to time appoint one or more successor or additional branch registrars and may from time to time rescind any such appointment.

The principal register together with each branch register is sometimes referred to herein as the “Securities Register”, and the principal registrar together with each branch registrar is sometimes referred to herein as the “Securities Registrar”. In the event of any conflict between the principal register and any branch register, the principal register shall be determinative.

Upon surrender for registration of transfer of any Security of any series at the Corporate Trust Office for that series, the Corporation shall execute, and one of the Trustees shall authenticate and deliver, in the name of the designated transferee, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

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

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the 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 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 with such signature guaranteed by a commercial bank reasonably acceptable to the Security Registrar or by a member of a national securities exchange.

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 14 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 the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part or (iii) 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.

3.6 Mutilated, Destroyed, Lost and Stolen Securities

If any mutilated Security is surrendered to either Trustee, the Corporation shall execute and such 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 or, in case any such mutilated Security 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.

If there shall be delivered to the Corporation and to either Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such surety or indemnity bond 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 such Trustee that such Security has been acquired by a bona fide purchaser, the Corporation shall execute and upon its request such Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, or, in case any such destroyed, lost or stolen Security 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.

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 Trustees) connected therewith.

Every new Security of any series, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, shall constitute an original additional contractual obligation of the Corporation, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone,

and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

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

3.7 Payment of 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 on any 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 interest on any Security may at the Corporation’s option be paid by mailing a cheque 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.

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

(i) The Corporation may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Corporation shall notify the Trustees in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Corporation shall deposit with one of the Trustees an amount of money in the Currency in which the Securities of such series are payable or shall make arrangements satisfactory to the Trustees 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 Trustees 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 Trustees of the notice of the proposed payment. The Trustees 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 mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose name the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (ii); or

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

(c) 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 Trustees of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date for such Note, which notice shall set forth the specific information to be contained in the Reset Notice (as defined below). Not later than 40 days prior to each Optional Reset Date, the Trustees 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) or method of determining such rate (or 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 Date 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 multiplier used to calculate such interest rate, if applicable) or method of determining such rate (or spread or spread multiplier, 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) or method of determining such

rate (or spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustees 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) or method of determining such higher interest rate (or 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 13 for repayment at the option of Holders except that the period for delivery or notification to one of the Trustees 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 one of the Trustees, 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.

3.8 Optional Extension of 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 (the “Final Maturity”) set forth on the face of such Security. The Corporation may exercise such option with respect to any Security by notifying the Trustees 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”), which notice shall set forth the specific information to be contained in the Extension Notice (as defined below). If the Corporation exercises such option, the Trustees 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 Maturity, (ii) the new Stated Maturity, (iii) the interest rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustees’ 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.

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 Trustees 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 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 13 for repayment at the option of Holders, except that the period for delivery or notification to one of the Trustees 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 one of the Trustees revoke such tender for repayment until the close of business on the tenth day before the Original Stated Maturity.

3.9 Persons Deemed Owners

Prior to due presentment of a Security for registration of transfer, the Corporation, the Trustees and any agent of the Corporation or the Trustees may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 3.5 and 3.7) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Corporation, the Trustees nor any agent of the Corporation or the Trustees shall be affected by notice to the contrary.

None of the Corporation, the Trustees, 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 Trustees, or any agent of the Corporation or the Trustees, 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 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.

3.10 Cancellation

All Securities 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 a Trustee, be delivered to one of the Trustees. All Securities so delivered shall be promptly cancelled by such Trustee. The Corporation may at any time deliver to one of the Trustees for cancellation any Securities

previously authenticated and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and may deliver to one of the Trustees (or to any other Person for delivery to one of the Trustees) 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 such Trustee. If the Corporation shall so acquire any of the Securities, however, 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 one of the Trustees 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. Each Trustee shall deliver its certificate of cancellation to the Corporation.

3.11 Computation of Interest

Except as otherwise specified as contemplated by Section 3.1 with respect to any Securities, interest 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 of disclosure under the Interest Act (Canada), the yearly rate of interest to which any rate of interest payable under a Security, which is to be calculated on any basis other than a full calendar year, is equivalent may be determined by multiplying the rate by a fraction, the numerator of which is the number of days in the calendar year in which the period for which interest at such rate is payable and the denominator of which is the number of days comprising such other basis.

3.12 Currency and Manner of Payments in Respect of Securities

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, payment of the principal of (and premium, if any) and interest, if any, on the Securities of any series will be made in the Currency in which such Securities are payable.

ARTICLE 4
SATISFACTION AND DISCHARGE

4.1 Satisfaction and Discharge of Indenture

This Indenture shall upon Corporation Request cease to be of further effect with respect to any series of Securities (except as to any surviving rights of registration of transfer or exchange of Securities of such series herein expressly provided for and the Trustees, at the expense of the Corporation, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series) when

(a) either

(i) all Securities of such series previously authenticated and delivered (other than (i) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.6 and (ii) Securities of such series for whose payment money has theretofore been deposited with one of the Trustees or any Paying Agent and

thereafter repaid to the Corporation, as provided in Section 10.3) have been delivered to the Trustees for cancellation; or

(ii) all Securities of such series not previously delivered to the Trustees for cancellation

A. have become due and payable, or

B. will become due and payable at their Stated Maturity within one year, or

C. if redeemable at the option of the Corporation, are to be called for redemption within one year under arrangements satisfactory to the Trustees for the giving of notice of redemption by the Trustees in the name, and at the expense, of the Corporation,

and the Corporation, in the case of A, B or C above, has deposited or caused to be deposited with one of the Trustees as trust funds in trust for the purpose an amount, in the Currency in which the Securities of such series are payable, sufficient to pay and discharge the entire indebtedness on such Securities not previously delivered to the Trustees for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

(iii) the Corporation has paid or caused to be paid all other sums payable hereunder by the Corporation; and

(iv) the Corporation has delivered to the Trustees an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Corporation to the Trustees under Section 6.8, if money shall have been deposited with one of the Trustees pursuant to subclause B of clause (a) of this Section, the obligations of such Trustee under Section 4.2 and the last paragraph of Section 10.3 shall survive.

4.2 Application of Trust Money

Subject to the provisions of the last paragraph of Section 10.3, all money deposited with a 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 such Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with such Trustee; but such money need not be segregated from other funds except to the extent required by law.

ARTICLE 5

5.1 Events of Default

“Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

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

5.2 Acceleration of Maturity; Rescission and Annulment

If an Event of Default (other than an Event of Default described in clause (d) of Section 5.1 or an Event of Default relating to the Corporation (but not any Material Subsidiary) described in clause (f) or (g) of Section 5.1 with respect to Securities of any series at the time Outstanding occurs and is continuing), then in every such case the Trustees or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the

principal amount as may be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustees if given by Holders), and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable. If an Event of Default described in clause (d) of Section 5.1 occurs and is continuing, then in every such case the Trustees or the Holders of not less than 25% in principal amount of all the Securities then Outstanding may declare the principal amount (or, if any such Securities are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Outstanding Securities to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustees if given by the Holders) and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable. If an Event of Default with respect to the Corporation (but not any Material Subsidiary) described in clause (f) or (g) of Section 5.1 occurs, the principal amount of all the Securities then Outstanding shall automatically, and without any declaration or other action on the part of the Trustees or any Holder, become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series (or of all series, as the case may be) has been made and before a judgment or decree for payment of the money due has been obtained by the Trustees as hereinafter in this Article provided, 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 Trustees, may rescind and annul such declaration and its consequences if

(a) the Corporation has paid or deposited with either or both of the Trustees a sum sufficient to pay in the Currency in which the Securities of such series are payable,

(i) all overdue interest on all Outstanding Securities of that series (or of all series, as the case may be),

(ii) all unpaid principal of (and premium, if any, on) 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 any interest on such unpaid principal at the rate or rates prescribed therefor in such Securities,

(iii) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and

(iv) all sums paid or advanced by the Trustees hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel; and

(b) 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.

Notwithstanding the preceding paragraph, in the event of a declaration of acceleration in respect of the Securities because of an Event of Default specified in Section 5.1(e) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Debt that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such Debt, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustees by the Corporation and countersigned by the holders of such Debt or a trustee, fiduciary or agent for such holders, within 30 days after such declaration of acceleration in respect of the Securities, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period.

5.3 Collection of Indebtedness and Suits for Enforcement by Trustees

The Corporation covenants that if

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

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

(c) default is made in the payment of any sinking or purchase fund or analogous obligation when the same becomes due pursuant to the terms of any Security,

then the Corporation will, upon demand of the Trustees, pay to either or both of the Trustees, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and to the extent that payment of such interest shall be legally enforceable, 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 Trustees, their agents and counsel.

If the Corporation fails to pay such amounts forthwith upon such demand, the Trustees, in their own names and as trustees 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 Trustees may in their discretion proceed to protect and enforce their 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 Trustees shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

5.4 Trustees 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 Trustees (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 Trustees 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,

(a) 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 as may be specified in the terms of such series, and interest owing and unpaid in respect of the Securities and to file such other papers or documents and take such other actions, including participating as a member, voting or otherwise, of any official committee of creditors appointed in such matter, as may be necessary or advisable in order to have the claims of the Trustees (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel) and of the Holders allowed in such judicial proceeding, and

(b) 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 Trustees and, in the event that the Trustees shall consent to the making of such payments directly to the Holders, to pay to the Trustees any amount due them for the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel, and any other amounts due the Trustees under Section 6.8.

Nothing herein contained shall be deemed to authorize the Trustees 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 Trustees to vote in respect of the claim of any Holder in any such proceeding except as aforesaid, to vote for the election of a trustee in bankruptcy or similar person or to participate as a member, voting or otherwise on any committee of creditors.

5.5 Trustees May Enforce Claims Without Possession of Securities

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustees without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustees shall be brought in their own names as trustees 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 Trustees, their agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

5.6 Application of Money Collected

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

First: to the payment of all amounts due the Trustees under Section 6.8;

Second: to the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities 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 for principal (and premium, if any) and interest, respectively, in the order of principal first, then premium and then accrued and unpaid interest on amounts in default; and

Third: the balance, if any, to the Person or Persons entitled thereto or as a court of competent jurisdiction may direct.

5.7 Limitation on Suits

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

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

(b) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series in the case of any Event of Default described in clause (a), (b), (c), (e) or (h) of Section 5.1, or, in the case of any Event of Default described in clause (d), (f) or (g) of Section 5.1, the Holders of not less than 25% in principal amount of all Outstanding Securities, shall have made written request to the Trustees to institute proceedings in respect of such Event of Default in their own names as Trustees hereunder;

(c) such Holder or Holders have offered to the Trustees reasonable funding, security and indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustees for 60 days after their receipt of such notice, request and offer of funding, security and indemnity have failed to institute any such proceeding; and

(e) no direction inconsistent with such written request has been given to either Trustee during such 60-day period by the Holders of not less than a majority in principal amount of the Outstanding Securities of that series in the case of any Event of Default described in clause (a), (b), (c), (e) or (h) of Section 5.1, or, in the case of any Event of Default described in clause (d), (f) or (g) of Section 5.1, by the Holders of not less than a majority in principal amount of all Outstanding Securities;

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 Securities of the same series, in the case of any Event of Default described in clause (a), (b), (c), (e) or (h) of Section 5.1, or of Holders of all Securities in the case of any Event of Default described in clause (d), (f) or (g) of Section 5.1, 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 Securities of the same series, in the case of any Event of Default described in clause (a), (b), (c), (e) or (h) of Section 5.1, or of Holders of all Securities in the case of any Event of Default described in clause (d), (f) or (g) of Section 5.1.

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 14) and in such Security, of the principal of (and premium, if any) and (subject to Section 3.7) interest on, such Security on the respective due dates expressed in such Security (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.

5.9 Restoration of Rights and Remedies

If the Trustees 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 Trustees or to such Holder, then and in every such case, subject to any determination in such proceeding, the Corporation, the Trustees and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustees and the Holders shall continue as though no such proceeding had been instituted.

5.10 Rights and Remedies Cumulative

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustees or to the Holders of Securities 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.

5.11 Delay or Omission Not Waiver

No delay or omission of the Trustees or either of them or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustees or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustees or by the Holders, as the case may be.

5.12 Control by Holders

With respect to the Securities of any series, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustees, or exercising any trust or power conferred on the Trustees, relating to or arising under clause (a), (b), (c), (e) or (h) of Section 5.1, and, with respect to all Securities, the Holders of not less than a majority in principal amount of all Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustees, or exercising any trust or power conferred on the Trustees, not relating to or arising under clause (a), (b), (c), (e) or (h) of Section 5.1, provided that in each case

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

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

(c) the Trustees need not take any action which might involve either of them in personal liability or be unjustly prejudicial to either of them or to the Holders of Securities of such series not taking part in such direction or to the Holders of Securities of any other series.

5.13 Waiver of Past Defaults

Subject to Section 5.2, the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default described in clause (a), (b), (c), (e) or (h) of Section 5.1 (or, in the case of a default described in clause (d), (f) or (g) of Section 5.1, the Holders of not less than a

majority in principal amount of all Outstanding Securities may waive any such past default), and its consequences, except a default

(a) in respect of the payment of the principal of (or premium, if any, on) or interest on any Security, or

(b) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

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.

ARTICLE 6
THE TRUSTEES

6.1 Joint Trustees

The rights, powers, duties and obligations conferred and imposed upon the Trustees are conferred and imposed upon and shall be exercised and performed by the U.S. Trustee and the Canadian Trustee jointly, except to the extent otherwise provided herein and except to the extent that, under Trust Indenture Legislation, either Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by the Trustee which is not so incompetent or unqualified. If the Trustees are unable to agree jointly to act or refrain from acting with respect to any right, power, duty or obligation conferred jointly upon the Trustees hereunder, the reasonable decision of the U.S. Trustee to act or refrain from acting shall be binding upon the Canadian Trustee.

6.2 Duty of Trustees

In the exercise of the powers, rights, duties and obligations prescribed or conferred by the terms of this Indenture, each Trustee shall exercise that degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances and act honestly and in good faith with a view to the best interests of the Holders of the Securities.

6.3 Notice of Defaults

Each Trustee shall promptly give the other Trustee notice of any Default or Event of Default known to it. The Trustees, or either of them, shall, within a reasonable time but not exceeding 30 days after they become aware of the occurrence of any default hereunder, transmit by mail to all Holders, as their names and addresses appear in the Security Register, notice of such default, 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 on any Security of such series or in the payment of any sinking fund installment with respect to Securities of such series, the Trustees 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 Trustees in good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series; and provided further that in the case of any default or breach of the character specified in Section 5.1(d) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series.

6.4 Certain Rights of Trustees

No provision of this Indenture shall be construed to relieve either of the Trustees from its duties, except that to the extent permitted by Trust Indenture Legislation:

Whenever the Corporation shall have one or more Paying Agents for any series of Securities, it will, three Business Days prior to each due date of the principal of (and premium, if any, on) or interest on any Securities of that series, deposit with a Paying Agent a sum (in the Currency described in the preceding paragraph) sufficient to pay the principal (and premium, if any, on) or interest 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 a Trustee) the Corporation will promptly notify the Trustees of its action or failure so to act.

The Corporation will cause each Paying Agent (other than a Trustee) for any series of Securities to execute and deliver to the Trustees an instrument in which such Paying Agent shall agree with the Trustees, subject to the provisions of this Section, that such Paying Agent will:

(a) hold all sums held by it for the payment of the principal of (and premium, if any) and interest 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;

(b) give the Trustees 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 on the Securities of such series; and

(c) at any time during the continuance of any such default, upon the written request of the Trustees, forthwith pay to the Trustees 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 Trustees all sums held in trust by the Corporation or such Paying Agent, such sums to be held by the Trustees upon the same trusts as those upon which sums were held by the Corporation or such Paying Agent; and, upon such payment by any Paying Agent to the Trustees, 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 Trustees or any Paying Agent, or then held by the Corporation, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Corporation on Corporation Request subject to applicable abandoned property or escheat law, or (if then held by the Corporation) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Corporation for payment thereof, and all liability of the Trustees 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 Trustees or such Paying Agent, before being required to make any such

repayment, may 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.

10.4 Corporate Existence

Subject to Article 8, the Corporation will at all times maintain its corporate existence and will carry on and conduct its business in a proper and efficient manner and will keep or cause to be kept proper books of account and will file with the Trustees copies of all financial statements of the Corporation furnished or required to be furnished to its shareholders; provided, however, that nothing herein contained shall prevent the Corporation from ceasing to operate any premises or property if, in the opinion of the Board of Directors, it shall be advisable and in the best interests of the Corporation so to do.

10.5 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 set forth in Section 10.4, inclusive, if before the time for such compliance the Holders of not less than a majority in principal amount of all Outstanding Securities affected by such term, provision or covenant, 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 Trustees to Holders of Securities of such series in respect of any such term, provision or condition shall remain in full force and effect.

10.6 Annual Compliance Certificate

The Corporation shall deliver to the Trustees, within 90 days after the end of each calendar year, an Officers’ Certificate as to the knowledge of the Officers who execute the Certificate, of the Corporation’s compliance with all conditions and covenants of this Indenture, certifying that after reasonable investigation and inquiry, they are satisfied the Corporation has complied with all covenants, conditions or other requirements contained in the Indenture, the non-compliance with which could, with the giving of notice, lapse of time or otherwise, constitute an Event of Default hereunder, or if such is not the case, setting forth with reasonable particulars any steps taken or proposed to be taken to remedy such Event of Default.

ARTICLE 11
REDEMPTION OF SECURITIES

11.1 Applicability of Article

Securities of any series which are redeemable before their Stated Maturity shall be redeemable 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.

11.2 Election to Redeem; Notice to Trustees

The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Corporation of less than all the Securities of any series, the Corporation shall, at least 60 days prior to the Redemption Date fixed by the Corporation (unless a shorter notice shall be satisfactory to the Trustees), notify the Trustees of such Redemption Date and of the principal amount of Securities of such series to be redeemed and shall deliver to the Trustees such documentation and records as shall enable the Trustees to select the Securities to be redeemed pursuant to Section 11.3. 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 Trustees with an Officers’ Certificate evidencing compliance with such restriction.

11.3 Selection by Trustees of Securities to be Redeemed

If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustees, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustees shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal of Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series established pursuant to Section 3.1.

The Trustees shall promptly notify 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.

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 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

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 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.

All notices of redemption shall state:

(a) the Redemption Date,

(b) the Redemption Price,

(c) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed,

(d) that on the Redemption Date the Redemption Price (together with 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,

(e) the place or places where such Securities are to be surrendered for payment of the Redemption Price,

(f) that the redemption is for a sinking fund, if such is the case.

Notice of redemption of Securities to be redeemed at the election of the Corporation shall be given by the Corporation or, at the Corporation’s request, by the Trustees in the name and at the expense of the Corporation.

11.5 Deposit of Redemption Price

One Business Day prior to any Redemption Date, the Corporation shall deposit with the Trustees 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 sufficient to pay the Redemption Price of, and accrued interest on, all the Securities which are to be redeemed on that date.

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 (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) such Securities shall, if the same were interest-bearing, cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, 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 Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable (but without interest thereon, unless the Corporation shall default in the payment thereof) 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 any Security called for redemption shall not be 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 the Security.

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 12) shall be surrendered at a Place of Payment therefor (with, if the Corporation or either Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Corporation and the Trustees or either of them duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Corporation shall execute, and the Trustees or either of them 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.

ARTICLE 12
SINKING FUNDS

12.1 Applicability of Article

Retirements of Securities of any series pursuant to any sinking fund 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.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

12.2 Satisfaction of Sinking Fund Payments with Securities

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 Trustees Outstanding Securities of a series (other than any previously called for redemption) previously purchased or otherwise acquired by the Corporation and/or (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustees by the Corporation or 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 Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustees 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.

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 Trustees 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 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 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 Trustees 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 Trustees 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 U.S.$100,000, the Trustees, 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, 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 Trustees or any paying agent will be reimbursed by the Corporation) determined by the Corporation but not in excess of the principal amount thereof.

ARTICLE 13
REPAYMENT AT OPTION OF HOLDERS

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.

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 the Business Day preceding the Repayment Date it will deposit with a 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 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 on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

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 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.

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. 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 installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Corporation shall default in the payment thereof) 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.

13.5 Securities Repaid in Part

Upon surrender of any Security which is to be repaid in part only, the Corporation shall execute and one of the Trustees shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Corporation, a new Security or Securities of the same series of like tenor, 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

14.1 Corporation’s Option to Effect Defeasance or Covenant Defeasance

Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, 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 shall be made, at the Corporation’s option by Board Resolution at any time, in accordance with the terms of such Securities and in accordance with this Article.

14.2 Defeasance and Discharge

Upon the Corporation’s exercise 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 its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustees, 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 and 10.3, (C) the rights, powers, trusts, duties and immunities of the Trustees hereunder and (D) this Article 14. Subject to compliance with this Article 14, the Corporation may exercise its option under this Section 14.2 notwithstanding the prior exercise of its option under Section 14.3 with respect to such Securities.

14.3 Covenant Defeasance

Upon the Corporation’s exercise 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 10.4, and, if specified pursuant to Section 3.1, its 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 to be not Outstanding for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with Section 10.4, or such other covenant, 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 Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other 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(d) or Section 5.1(h) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

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.

(a) The Corporation shall irrevocably have deposited or caused to be deposited with the Trustees (or another trustee satisfying the requirements of Section 6.10 who shall agree to comply with the provisions of this Article 14 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 (including any premium) 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 public accountants expressed in a written certification thereof delivered to the Trustees, to pay and discharge, and which shall be applied by the Trustees (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium, if any) and interest on such Outstanding Securities on the Stated Maturity (or Redemption Date, if applicable) of such principal or installment of principal or interest 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. Before such a deposit, the Corporation may give to the Trustees, in accordance with Section 11.2 hereof, a notice of its election to redeem all or any part of such Securities at a future date in accordance with Article 11 hereof and the terms of such Securities, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(b) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs (f) or (g) of Section 5.1 are concerned, at any time during the three-month period after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(c) In the case of an election under either Section 14.2 and 14.3, the Corporation is not an “insolvent person” within the meaning of the Bankruptcy Act (Canada) on the date of such deposit or at any time during the three-month period after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(d) 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.

(e) In the case of an election under Section 14.2, the Corporation shall have delivered to the Trustees an Opinion of Counsel in the United States stating that (x) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of this Indenture, there has been a change in the applicable 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 federal income tax purposes as a result of such defeasance and will be subject to 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.

(f) In the case of an election under Section 14.3, the Corporation shall have delivered to the Trustees an Opinion of Counsel in the United States to the effect that the Holders of such Outstanding Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to 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.

(g) In the case of an election under either Section 14.2 or 14.3, the Corporation shall have delivered to the Trustees an Opinion of Counsel in Canada to the effect that Holders of the Outstanding Securities will not recognize income, gain or loss for Canadian federal or provincial income tax or other tax purposes as a result of such defeasance or covenant defeasance, as applicable, and will be subject to Canadian federal and 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 if such defeasance or covenant defeasance, as applicable, had not occurred.

(h) In the case of an election under either Section 14.2 and 14.3, the Corporation shall have delivered to the Trustees an Officers’ Certificate stating that the deposit made by the Corporation pursuant to its election under Section 14.2 or 14.3 was not made by the Corporation with the intent of preferring the Holders over other creditors of the Corporation or with the intent of defeating, hindering, delaying or defrauding creditors of the Corporation or others.

(i) 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.

(j) The Corporation shall have delivered to the Trustees 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.

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 Trustees (or other qualifying trustee—collectively for purposes of this Section 14.5, the “Trustee”) pursuant to Section 14.4 in respect of any Outstanding Securities of such series 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, but such money need not be segregated from other funds except to the extent required by law.

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 14 to the contrary notwithstanding, the Trustee shall deliver or pay to the Corporation from time to time upon 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 public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article.

ARTICLE 15
SUBMISSION TO JURISDICTION

15.1 Agent for Service; Submission to Jurisdiction; Waiver of Immunities

By the execution and delivery of this Indenture, the Corporation (i) acknowledges that it has, by separate written instrument, irrevocably designated and appointed IESI Corporation, 2301 Eagle Parkway, Suite 200, Fort Worth, Texas, 76177 as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Securities or this Indenture that may be instituted in any federal or New York state court located in the City of New York, or brought by either Trustee (whether in its individual capacity or in its capacity as Trustee hereunder), and acknowledges that IESI Corporation has accepted such designation, (ii) submits to the jurisdiction of any such court in any such suit or proceeding, and (iii) agrees that service of process upon IESI Corporation and written notice of said service to it (mailed or delivered to its Secretary at its principal office in Toronto, Canada as specified in Section 1.5 hereof, shall be deemed in every respect effective service of process upon it in any such suit or proceeding. 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 IESI Corporation in full force and effect so long as this Indenture shall be in full force and effect.
