If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Sixteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustees and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustees and the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 16.06.

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 Registered Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

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

Securities held by any Person, and the date of holding the same, may also be proved in any other manner that the Trustees deem sufficient.

(e) If the Company shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding Trust Indenture Legislation, including 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 eleven months after the record date.

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

Section 1.05 Notices, etc. to Trustees and Company

Section 1.06 Notice to Holders; Waiver

Where this Indenture provides for notice of any event to Holders of Registered Securities by the Company or the Trustees, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

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

Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 3.01, where this Indenture provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper in The City of New York and in such other city or cities as may be specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice. Any such notice shall be deemed to have been given on the date of the first such publication.

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

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

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustees, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(c) The obligations contained in Subsections (a)(ii) and (b) of this Section shall constitute separate and independent obligations of the Company from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Company, shall apply irrespective of any waiver or extension granted by any Holder or the Trustees or either of them from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Company for a liquidated sum in respect of amounts due hereunder (other than under Subsection (b) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustees, as the case may be, and no proof or evidence of any actual loss shall be required by the Company or its liquidator. In the case of Subsection (b) above, the amount of such deficiency shall not be deemed to be increased or reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

The term “rate(s) of exchange” shall mean the rate of exchange quoted by a Canadian chartered bank as may be designated in writing by the Company to the Trustees from time to time, at its central foreign exchange desk in its main office in Toronto at 12:00 noon (Toronto time) on the relevant date for purchases of the Base Currency with the Judgment Currency and includes any premiums and costs of exchange payable. The Trustees shall have no duty or liability with respect to monitoring or enforcing this Section.

Section 1.15 Currency Equivalent

Except as otherwise provided in this Indenture, for purposes of the construction of the terms of this Indenture or of the Securities, in the event that any amount is stated herein in the Currency of one nation (the “First Currency”), as of any date such amount shall also be deemed to represent the amount in the Currency of any other relevant nation (the “Other Currency”) which is required to purchase such amount in the First Currency at the Bank of Canada noon rate as reported by Telerate on screen 3194 (or such other means of reporting the Bank of Canada noon rate as may be agreed upon by each of the parties to this Indenture) on the date of determination.

Section 1.16 Conflict with Trust Indenture Legislation

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with any mandatory requirement of Trust Indenture Legislation, such mandatory requirement shall control. If and to the extent that any provision hereof limits, qualifies or conflicts with the duties imposed by any of Sections 310 to 318, inclusive, of the Trust Indenture Act, through operation of Section 318(c) thereof, such duties shall control.

Section 1.17 Incorporators, Shareholders, Officers and Directors of the Company Exempt from Individual Liability

No recourse under or upon any obligation, covenant or agreement contained in this Indenture, or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such, or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the Holders and as part of the consideration for the issue of the Securities.

Section 3.03 Execution, Authentication, Delivery and Dating

The Securities and any coupons appertaining thereto shall be executed on behalf of the Company by its President, Chief Executive Officer, Chief Operating Officer, Chief Financial Officer together with the Corporate Secretary of the Company. If two or more persons share such office any one of such persons may. The signature of any of these officers on the Securities or coupons may be the manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities.

Securities or coupons bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, 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 or coupons.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series together with any coupon appertaining thereto, executed by the Company to the applicable Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the applicable Trustee in accordance with such Company Order shall authenticate and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the United States; and provided further that, unless otherwise specified with respect to any series of Securities pursuant to Section 3.01, a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in Exhibit A-1 to this Indenture, dated no earlier than 15 days prior to the earlier of the date on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security, then, for purposes of this Section and Section 3.04, the notation of a beneficial owner’s interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial owner’s interest in such permanent global Security. Except as permitted by Section 3.06, the Trustees shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and cancelled. If not all the Securities of any series are to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustees for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, stated maturity, date of issuance and date from which interest shall accrue.

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

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

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

(c) that such Securities, together with any coupons appertaining thereto, when completed by appropriate insertions and executed and delivered by the Company to the Trustees for authentication in accordance with this Indenture, authenticated and delivered by the Trustees, or either of them, in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legal, valid and binding obligations of the Company, 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 and 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 any coupons;

(d) that all laws and requirements in respect of the execution and delivery by the Company of such Securities, any coupons and of the supplemental indentures, if any, have been complied with and that authentication and delivery of such Securities and any coupons and the execution and delivery of the supplemental indentures, if any, by the Trustees will not violate the terms of the Indenture;

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

(f) that the issuance of such Securities and any coupons will not contravene the articles of incorporation or continuance, or such other constating documents then in effect, if any, or by-laws of the Company or result in any violation of any of the terms or provisions of any law or regulation or of any indenture, mortgage or other agreement known to such Counsel by which the Company is bound.

Notwithstanding the provisions of Section 3.01 and of the preceding two paragraphs, if not all the Securities of any series are to be issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.01 or the Company Order and Opinion of Counsel otherwise required pursuant to the preceding two paragraphs prior to or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series.

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

Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated by Section 3.01.

No Security or coupon shall entitle a Holder to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the U.S. Trustee or by the Canadian Trustee by manual signature of an authorized officer, and such certificate upon any Security shall be

conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustees for cancellation as provided in Section 3.10 together with a written statement (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never entitle a Holder to the benefits of this Indenture.

Section 3.04 Temporary Securities

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order, the Trustees, or either of them, shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Notwithstanding that procedure, Canadian Securities issued in temporary form must be returned to the Canadian Trustee for cancellation. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining thereto), the Company shall execute and either Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 3.03. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the office of a depositary or common depositary (the “Common Depositary”) or the Depositary, as applicable, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security (the “Exchange Date”), the Company shall deliver to the Trustees definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustees, as the Company’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge and either Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 3.01, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided, however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by the Depositary as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date, each in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established pursuant to Section 3.01); and provided further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security only in compliance with the requirements of Section 3.03.

Unless otherwise specified in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs the Depositary to request such exchange on his behalf and delivers to the Depositary a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 3.01), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate shall be available from the offices of the Depositary, the Trustees, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like in the event that such Person does not take delivery of such definitive Securities in person at the offices of the Depositary. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall be delivered only outside the United States.

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 3.01, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to the Depositary on such Interest Payment Date upon delivery by the Depositary to the Trustees of a certificate or certificates in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established pursuant to Section 3.01), for credit without further interest thereon on or after such Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have

each delivered to the Depositary a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 3.01). Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this Section and of the third paragraph of Section 3.03 of this Indenture and the interests of the Persons who are the beneficial owners of the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange Date or the date of certification if such date occurs after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or interest, if any, owing with respect to a beneficial interest in a temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by the Depositary and not paid as herein provided shall be returned to the Trustees immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company in accordance with Section 11.03.

Section 3.05 Registration, Registration of Transfer and Exchange

So long as required by Trust Indenture Legislation, the Company shall cause to be kept at the Corporate Trust Offices of the Trustees a register for each series of Securities(the registers maintained in the Corporate Trust Offices of the Trustees and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Central Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Holders of Registered Securities and of transfers of Registered Securities. The Central Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Central Register shall be open to inspection by the Trustee. The Company will cause the particulars of each such issue, exchange or transfer of Securities to be recorded in the Central Register. The Company hereby appoints the Canadian Trustee as the Central Registrar and Transfer Agent for the Canadian Securities and the U.S. Trustee as the Central Registrar and Transfer Agent for the U.S. Securities (collectively, the “Central Securities Registrars”). There shall be two such Central Registers, one for U.S. Securities and one for Canadian Securities. If permitted by Trust Indenture Legislation, the Company may appoint a Person other than the Company or a trust corporation registered under the Trust and Loan Companies Act, S.C. 1991, c. 45 as the Central Securities Registrar; provided that, no such removal or replacement shall be effective until a successor Central Security Registrar with respect to such series of Registered Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustees shall not be or shall cease to be the Central Securities Registrar with respect to a series of Securities, it shall have the right to examine the Central Register for such series at all reasonable times. There shall be only one Central Securities Register for such series of Securities.

The Company may, subject to the consent of the Appropriate Trustee, also cause to be maintained a branch register (a “Branch Register”) or Branch Registers of Holders of Securities in accordance with Section 11.02 in the same manner and containing the same information with respect to each entry contained therein as contained in the Central Register. A copy of every entry in a Branch Register shall, promptly after the entry is made, be transmitted to the Central Security

Registrar. If there is a conflict between the information contained in the Central Register and the information contained in the Branch Register, the information contained in the Central Register shall prevail. The Central Register together with each Branch Register are collectively referred to herein as the “Security Register”. At all reasonable times, the Security Register shall be open to inspection by the Trustees. The Company may appoint from time to time one or more branch security registrars (“Branch Security Registrars”) and may from time to time rescind any such appointment. The Central Security Registrar together with each Branch Security Registrar are collectively referred to herein as the “Security Registrar”.

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

For Canadian Securities, the Security must be duly endorsed for transfer or in a duly endorsed transferable form as applicable and must comply with the current industry practice in accordance with the Securities Transfer Association of Canada.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denomination and of a like aggregate principal amount, upon surrender of the Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Appropriate Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to any series of Securities as contemplated by Section 3.01, Bearer Securities may not be issued in exchange for Registered Securities. The Appropriate Trustee shall update the Register, or, if the Appropriate Trustee is not the Authenticating Agent, the Appropriate Trustee shall immediately provide a copy of the newly Authenticated Security to the Central Registrar so that the Register may be updated.

If (but only if) expressly permitted in or pursuant to the applicable Board Resolution and (subject to Section 3.03) set forth in the applicable Officers’ Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 3.01, at the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at the office of the Appropriate Trustee, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustees if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 11.02, interest represented by

coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture.

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

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent global Security is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as contemplated by Section 3.01 and provided that any applicable notice provided in the permanent global Security shall have been given to the Company, the Appropriate Trustee and the Common Depositary, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall deliver to the Appropriate Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Company Order with respect thereto to the Appropriate Trustee, as the Company’s agent for such purpose, to be exchanged in whole or from time to time in part, for definitive Securities without charge, and the Appropriate Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged which, unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, as specified as contemplated by Section 3.01, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof. The Appropriate Trustee shall promptly provide to the Common Depositary (or other applicable Depositary) a replacement global Security in the aggregate principal amount of the global Security not being so exchanged. The Appropriate Trustee shall note the exchange on the register for such Securities. Notwithstanding the foregoing, no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption; and provided, further, that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or

agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

Transfers of global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. If at any time the Depositary of a series notifies the Company that it is unwilling, unable or no longer qualifies to continue as Depositary of such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or regulation, the Company shall appoint a successor depositary with respect to the Securities for such series. If a successor to the Depositary is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, the Company’s election pursuant to Section 3.01 shall no longer be effective with respect to the Securities for such series and the Company will execute, and the Appropriate Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive, registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

The Company may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more global Securities shall no longer be represented by such global Security or Securities. In such event the Company will execute, and the Appropriate Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive, registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

Interests of a beneficial owner in global Securities may also be transferred or exchanged for definitive Securities if, after the occurrence of an Event of Default with respect to such Securities, and while such Event of Default is continuing, such owner notifies the Trustees in writing that it wishes to receive a Security in definitive, registered form and provides to the Trustees evidence reasonably satisfactory to the Trustees of its ownership interest in such Securities. In such event the Company will execute, and the Appropriate Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive, registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

Upon the exchange of a global Security for Securities in definitive registered form, such global Security shall be cancelled by the Appropriate Trustee. Securities issued in exchange for a global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Appropriate Trustee in writing. The Appropriate Trustee shall deliver such Securities to the persons in whose names such Securities are so registered.

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

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

Any registration of transfer or exchange of Securities may be subject to service charges by the Central Securities Registrar and the Company 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 3.04, Section 10.06, Section 12.07 or Section 14.05 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series in definitive form during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of that series under Section 12.03 or Section 13.03 and ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, (C) if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security in definitive form so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor; provided that such Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue, register the transfer of or exchange any Security in definitive form which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities

If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to either Trustee, the Company shall execute and either Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security, or, in case any such mutilated Security or coupon has become or is about to become due and payable, the Company in its discretion may,

instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security, pay such Security or coupon. If there shall be delivered to the Company and to either Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon and (ii) such security (or surety in the case of the Canadian Trustee) or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustees that such Security or coupon has been acquired by a protected purchaser (as defined in Article 8 of the UCC), the Company shall execute and upon Company Order either Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the Security for which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to such mutilated, destroyed, lost or stolen Security or to the Security to which such mutilated, destroyed, lost or stolen coupon appertains, pay such Security or coupon; provided, however, that payment of principal of (and premium, if any) and interest, if any, on Bearer Securities shall, except as otherwise provided in Section 11.02, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 3.01, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto.

Upon the issuance of any new Security under this Section, the Company 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 with its coupons, if any, issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security or in exchange for a Security to which a mutilated, destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security and its coupons, if any, or the mutilated, destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and the Holders of such Security shall be entitled to all the benefits of this Indenture equally and proportionately with the Holders of any and all other Securities of that series and their coupons, if any, duly issued hereunder.

The provisions of this Section as amended or supplemented pursuant to this Indenture with respect to particular securities or generally are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons.

Section 3.07 Payment of Principal; Premium; Interest; Interest Rights Preserved; Optional Interest Reset

(a) Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, principal of, and premium, if any, and interest, if any, on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date or other date in which the principal of, and premium, if any, is payable shall be paid by the Paying Agent 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 principal, premium or interest, as the case may be, at the office or agency of the Company maintained for such purpose pursuant to Section 11.02; provided, however, that each installment of principal of, and premium, if any, and interest, if any, on any Registered Security may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 3.09, to the address of such Person as it appears on the Security Register or (ii) transfer to an account located in the United States maintained by the payee of a Holder of $2.0 million or more in aggregate principal amount of such Securities (with wire transfer instructions provided to the Trustee not less than 15 days prior to payment of interest by wire transfer). The Paying Agent shall confirm in writing to the Canadian Trustee upon payment having been made to Holders of Canadian Securities within five days.

Unless otherwise provided as contemplated by Section 3.01 with respect to the Securities of any series, payment of interest, if any, may be made, in the case of a Bearer Security, by transfer to an account located outside the United States maintained by the payee.

Unless otherwise provided as contemplated by Section 3.01, every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to the Depositary with respect to that portion of such permanent global Security held for its account by the Common Depositary, for the purpose of permitting the Depositary to credit the interest, if any, received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such defaulted interest and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities of such series (such defaulted interest and, if applicable, interest thereon herein collectively called “Defaulted Interest”) must be paid by the Company as provided for in either clause (1) or (2), at the Company’s election:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustees in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with either Trustee an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities

of such series and except, if applicable, as provided in Section 3.12(b), Section 3.12(d) and Section 3.12(e)) equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the 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 Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided in Section 1.06, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose name the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

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

(b) The provisions of this Subsection may be made applicable to any series of Securities pursuant to Section 3.01 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.01). 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 Company on the date or dates specified on the face of such Security (each an “Optional Reset Date”). The Company 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 Security. Not later than 40 days prior to each Optional Reset Date, the Trustees shall transmit, in the manner provided for in Section 1.06, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity 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 Company may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or the spread or spread multiplier, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustees to transmit, in the manner provided for in Section 1.06, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable).

The Holder of any such Security will have the option to elect repayment by the Company 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 Fourteen for repayment at the option of Holders except that the period for delivery or notification to 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 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 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 3.08 Optional Extension of Stated Maturity

The provisions of this Section 3.08 may be made applicable to any series of Securities pursuant to Section 3.01 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.01). The Stated Maturity of any Security of such series may be extended at the option of the Company 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 Company 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”). If the Company exercises such option, the Trustees shall transmit, in the manner provided for in Section 1.06, 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 Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the interest rate, if any, applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the 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 Company 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 1.06, 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 Company extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Company 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 Company has extended the Maturity thereof, the Holder must follow the procedures set forth in Article Fourteen for repayment at the option of Holders, except that the period for delivery or notification to 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 the Trustees revoke such tender for repayment until the close of business on the tenth day before the Original Stated Maturity.

Section 3.09 Persons Deemed Owners

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustees and any agent of the Company or the Trustees may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 3.05 and Section 3.07) interest, if any, on such Security and for all other purposes whatsoever (other than the payment of Additional Amounts, if any), whether or not such Security be overdue, and none of the Company, the Trustees or any agent of the Company or the Trustees shall be affected by notice to the contrary.

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

The Depositary for Securities may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever (other than the payment of Additional Amounts, if any). None of the Company, 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 Company, the Trustees, or any agent of the Company 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.

Section 3.10 Cancellation

All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against any current or future sinking fund payment shall, if surrendered to any Person other than a Trustee, be delivered to a Trustee. All securities and coupons so delivered to either Trustee shall be promptly cancelled by it. The Company may at any time deliver to either Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to either Trustee (or to any other Person for delivery to such Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by such Trustee. If the Company 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 a Trustee for cancellation. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by a Trustee shall be disposed of by such Trustee in accordance with its customary procedures and certification of their disposal delivered to the Company unless by Company Order the Company shall direct that cancelled Securities be returned to it.

Section 3.11 Computation of Interest

Except as otherwise specified as contemplated by Section 3.01 with respect to any Securities, interest, if any, on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. For the purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which interest calculated under a Security for any period in any calendar year (the “calculation period”) is equivalent, is the rate payable under a Security in respect of the calculation period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator of which is the actual number of days in the calculation period. If the Canadian Trustee is appointed Paying Agent, it shall be entitled to rely on the calculations to be provided by the Company.

Section 3.12 Currency and Manner of Payments in Respect of Securities

(a) With respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or the Holders of which have not made the election provided for in paragraph (b) below, and with respect to Bearer Securities of any series, except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and interest, if any, on any Registered or Bearer Security of such series will be made in the Currency in which such Registered

Security or Bearer Security, as the case may be, is payable. The provisions of this Section may be modified or superseded with respect to any Securities pursuant to Section 3.01.

(b) It may be provided pursuant to Section 3.01 with respect to Registered Securities of any series that Holders shall have the option, subject to paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered Securities in any of the Currencies which may be designated for such election by delivering to the Trustees a written election with signature guarantees and in the applicable form established pursuant to Section 3.01, not later than the close of business on the Election Date immediately preceding the applicable payment date. If the Canadian Trustee or the U.S. Trustee is appointed Paying Agent, the ability to receive payments of principal of (or premium, if any) or interest, if any in the Currency designated for election will be subject to the Canadian Trustee’s or the U.S. Trustee’s ability, as Paying Agent, to accommodate payment in the Currency elected. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustees (but any such change must be made not later than the close of business on the Election Date immediately preceding the next payment date to be effective for the payment to be made on such payment date and no such change of election may be made with respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has occurred or with respect to which the Company has deposited funds pursuant to Articles Four or Fifteen or with respect to which a notice of redemption has been given by the Company or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Registered Security who shall not have delivered any such election to the Trustees not later than the close of business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant Currency as provided in Section 3.12(a). The Trustees shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Registered Securities for which Holders have made such written election.

(c) Unless otherwise specified pursuant to Section 3.01, if the election referred to in paragraph (b) above has been provided for pursuant to Section 3.01, then, unless otherwise specified pursuant to Section 3.01, not later than the fourth Business Day after the Election Date for each payment date for Registered Securities of any series, the Exchange Rate Agent will deliver to the Company a written notice specifying, in the Currency in which Registered Securities of such series are payable, the respective aggregate amounts of principal of (and premium, if any) and interest, if any, on the Registered Securities to be paid on such payment date, specifying the amounts in such Currency so payable in respect of the Registered Securities as to which the Holders of Registered Securities of such series shall have elected to be paid in another currency as provided in paragraph (b) above. If the election referred to in paragraph (b) above has been provided for pursuant to Section 3.01 and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 3.01, on the seventh Business Day preceding such payment date the Company will deliver to the Trustees for such series of Registered Securities an Exchange Rate Officers’ Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Unless otherwise specified pursuant to Section 3.01, the Dollar or Foreign Currency amount receivable by Holders of Registered Securities who have elected payment in a Currency as provided in paragraph (b) above shall be determined by the Company on the basis of the applicable Market Exchange Rate in effect on the eighth Business Day (the “Valuation Date”) immediately preceding

each payment date, and such determination shall be conclusive and binding for all purposes, absent manifest error.

(d) If a Conversion Event occurs with respect to a Foreign Currency in which any of the Securities are denominated or payable other than pursuant to an election provided for pursuant to paragraph (b) above, then, with respect to each date for the payment of principal of (and premium, if any) and interest, if any, on the applicable Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the Dollar shall be the Currency of payment for use on each such payment date. Unless otherwise specified pursuant to Section 3.01, the Dollar amount to be paid by the Company to the Trustees and by the Trustees or any Paying Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

(e) Unless otherwise specified pursuant to Section 3.01, if the Holder of a Registered Security denominated in any Currency shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment in Dollars as provided in paragraph (d) above.

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

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

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

A “Component Currency” shall mean any Currency which, on the Conversion Date, was a component currency of the relevant currency unit, including, but not limited to, the Euro.

A “Specified Amount” of a Component Currency shall mean the number of units of such Component Currency or fractions thereof which were represented in the relevant currency unit, including, but not limited to, the Euro, on the Conversion Date. If after the Conversion Date the official unit of any Component Currency is altered by way of combination or subdivision, the Specified Amount of such Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such Component Currencies shall be replaced by an amount in such single Currency equal to the sum of the respective Specified Amounts of such

consolidated Component Currencies expressed in such single Currency, and such amount shall thereafter be a Specified Amount and such single Currency shall thereafter be a Component Currency. If after the Conversion Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced by amounts of such two or more currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date of such replacement equal to the Dollar Equivalent value of the Specified Amount of such former Component Currency at the Market Exchange Rate immediately before such division and such amounts shall thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, including, but not limited to, the Euro, a Conversion Event (other than any event referred to above in this definition of “Specified Amount”) occurs with respect to any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion Date of such Component Currency.

“Election Date” shall mean the date for any series of Registered Securities as specified pursuant to clause (15) of Section 3.01 by which the written election referred to in paragraph (b) above may be made.

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

In the event that the Company determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Company will immediately give written notice thereof to the Trustees and to the Exchange Rate Agent (and the Trustees will promptly thereafter give notice in the manner provided for in Section 1.06 to the affected Holders) specifying the Conversion Date. In the event the Company so determines that a Conversion Event has occurred with respect to the Euro or any other currency unit in which Securities are denominated or payable, the Company will immediately give written notice thereof to the Trustees and to the Exchange Rate Agent (and the Trustees will promptly thereafter give notice in the manner provided for in Section 1.06 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion Date. In the event the Company determines in good faith that any subsequent change in any Component Currency as set forth in the definition of Specified Amount above has occurred, the Company will similarly give written notice to the Trustees and the Exchange Rate Agent.

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

Section 3.13 Appointment and Resignation of Successor Exchange Rate Agent

(a) Unless otherwise specified pursuant to Section 3.01, if and so long as the Securities of any series (i) are denominated in a Currency other than Dollars or (ii) may be payable in a Currency other than Dollars, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. The Company will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 3.01 for the purpose of determining the applicable rate of exchange and, if applicable, for the purpose of converting the issued Currency into the applicable payment Currency for the payment of principal (and premium, if any) and interest, if any, pursuant to Section 3.12.

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

(c) If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent for any cause with respect to the Securities of one or more series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Exchange Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series and that, unless otherwise specified pursuant to Section 3.01, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are originally issued by the Company on the same date and that are initially denominated and/or payable in the same Currency).

ARTICLE FIVE

SUBORDINATION OF THE SECURITIES

Section 5.01 Agreement to Subordinate

The Company covenants and agrees, and each Holder of Securities, by its acceptance thereof, likewise agrees, that the payment of the principal of, premium, if any, and interest on the Securities is hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness.

Section 5.02 Distribution on Insolvency or Winding-Up

In the event of any Senior Default or in the event that proceedings are commenced by or against the Company as a result of its insolvency or in the event of the liquidation or winding-up of the Company or if proceedings are commenced which effect a reorganization, arrangement, or compromise of debt of the Company:

(a) the holders of all Senior Indebtedness shall be entitled to receive payment in full of the principal thereof, the premium, if any, and the interest due thereon (including interest accruing after the commencement of any such proceeding at the rate specified in the instrument or agreement evidencing the Senior Indebtedness, whether or not such interest is an allowable claim in any such proceeding) before the Holders are entitled to receive any payment upon the principal of, premium, if any, and interest on indebtedness evidenced by the Securities;

(b) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders or the Trustees would be entitled except for the provisions of this Article 5 shall be paid by the Person making such payment or distribution, whether the liquidator, agent or other agent or a trustee in bankruptcy or a receiver or otherwise, directly to the holders of Senior Indebtedness or their representative or to the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay in full all Senior Indebtedness remaining unpaid after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness in respect thereof;

(c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, shall be received by the Trustees or the Holders before all Senior Indebtedness is paid in full, such payment or distribution shall be held in trust for the benefit of, and shall be paid over to, the holders of such Senior Indebtedness or their representative or to the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness in respect thereof; and

(d) any payments or distributions paid over to the holders of Senior Indebtedness pursuant to Section 5.02(c) and not applied in reduction of the amounts owing to the Holders hereunder shall be deemed not to have discharged any of the obligations of the Company hereunder (and, to the extent that by operation of applicable law they are treated as doing so, the Company covenants to indemnify the Holders on demand from and against any loss suffered or incurred by them in consequence thereof).

Upon any payment or distribution of assets of the Company referred to in this Article 5, the Trustees and the Holders shall be entitled to call for and rely upon a certificate, addressed to the Trustees or to the Holders, of the Person making any such payment or distribution for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 5.

Section 5.03 Subrogation of the Securities

Subject to the payment in full of all Senior Indebtedness, the Holders shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments and distributions of assets of the Company in respect of and on account of Senior Indebtedness, to the extent of the application thereto of moneys or other assets which would have been received by the Holders but for the provisions of this Article 5, until the principal of, premium, if any, and interest on the Securities shall be paid in full. No payment or distribution of assets of the Company to the Holders which would be payable or distributable to the holders of Senior Indebtedness pursuant to this Article shall, as between the Company, its creditors (other than the holders of Senior Indebtedness) and the Holders, be deemed to be a payment by the Company to or on account of the Holders, it being understood that the provisions of this Article 5 are, and are intended, solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained in this Article 5 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Company and its creditors (other than the holders of Senior Indebtedness and the Holders), the obligation of the Company, which is unconditional and absolute, to pay to the Holders the principal of, premium, if any, and interest on the Securities as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Holders and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustees or the Holder of any Securities from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 5, of the holders of Senior Indebtedness upon the exercise of any such remedy.

Section 5.04 No Payment to Holders if Senior Indebtedness Due or in Default or Commencement of Proceedings

(a) Upon the maturity of any Senior Indebtedness by lapse of time, acceleration or otherwise, then, except as hereinafter otherwise provided, all principal of, premium, if any, and interest on all such matured Senior Indebtedness shall first be paid in full, or shall first have been duly provided for, before any payment on account of principal of, premium, if any, and interest on the Securities is made.

In the event that, notwithstanding the foregoing, the Company shall make any payment of principal of, premium, if any, or interest on the Securities after the happening of such a default, then, except as hereinafter otherwise provided, unless and until such default shall have been cured or waived or shall have ceased to exist, such payments shall be held in trust for the benefit of, and if and when such Senior Indebtedness shall have become due and payable shall be paid over to, the holders of the Senior Indebtedness or their representative or to the trustee under any indenture under which any instruments evidencing any of the Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness in respect thereof.

(c) The fact that any payment which is required to be made pursuant to this Indenture or the Securities is prohibited by this Section 5.04 shall not prevent the failure to make such payment from being an Event of Default hereunder.

(d) The Company shall not grant and the Trustees and the Holders shall not be entitled to receive any mortgage, charge, hypothec, assignment, pledge or other security interest against any of the property, assets or undertaking of the Company or any of its Subsidiaries or Affiliates without the prior written consent of the holders of the Senior Indebtedness (other than trade creditors).

(e) Upon any default by the Company under this Indenture, the occurrence of any Event of Default or any Senior Default, neither the Trustees nor any Holder shall be entitled to take or commence any action, suit, remedy or proceedings (whether judicial or extra-judicial and including, without limitation, any action contemplated by Article 6) against the Company or any of its property, assets or undertaking to collect or enforce payment of the principal and interest on the Securities or any other amounts owing under this Indenture or to enforce the performance of any other covenant or obligation of the Company under this Indenture or the Securities (including, without limitation, any action or proceeding for the payment of any principal of or interest on the Securities, the appointment of a liquidator or receiver of the Company or any of its property, assets or undertaking for the winding up of the Company or pursuant to the Bankruptcy and Insolvency Act (Canada)) unless and until the Senior Indebtedness has been paid in full; provided however that the foregoing shall in no way prohibit, restrict or prevent the Trustees from filing proofs of claim in any bankruptcy, reorganization or insolvency proceedings commenced by or against the Company by any Person other than the Trustees or a Holder or taking steps in accordance with any subordination or postponement agreement entered into by the Trustees on their own behalf or on behalf of the Holders as contemplated by Section 5.10.

Section 5.05 Payment of Securities Permitted

(a) Subject always to Section 5.10, nothing contained in this Indenture or in any of the Securities shall prevent the Company at any time from making payments of the principal of, premium, if any on, or interest on the Securities provided that no such payments will be made if a Senior Default has occurred unless and until such default has been cured or waived or has ceased to exist.

(b) Until written notice shall be given to the Trustees by the Company or on behalf of any holder of any Senior Indebtedness of the occurrence of any Senior Default or of the existence of any other facts which would have the result that any payment with respect to the Securities would be in contravention of the provisions of this Article 5, the Trustees shall be entitled to assume that no such default has occurred, or that no such facts exist; and nothing in this Indenture shall prevent the Trustees, prior to receipt of such notice, from applying any moneys received by it pursuant to this Indenture prior to the receipt by it of such written notice, to the purposes for which the same were received, notwithstanding the occurrence or continuance of a default with respect to, or the existence of such facts with respect to, such Senior Indebtedness.

Section 5.06 Subordination Not to be Impaired

No right of any present or future holder of any Senior Indebtedness of the Company to enforce the subordination provided for in this Article shall at any time be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

Section 5.07 Obligations Created by Article 5

Each of the Company and the Trustees agrees, and each Holder of Securities, by its acceptance thereof, likewise agrees, that:

(a) the provisions of this Article 5 are an inducement and consideration to each holder of Senior Indebtedness to give or continue credit to the Company or others or to acquire Senior Indebtedness;

(b) each holder of Senior Indebtedness may accept the benefit of this Article 5 on the terms and conditions set forth in this Article 5 by giving or continuing credit to the Company or others or by acquiring Senior Indebtedness, in each case without notice to the Trustees or any Holder and without establishing actual reliance on this Article 5; and

(c) each obligation created by this Article 5 is created for the benefit of the holders of Senior Indebtedness and is hereby declared to be created in trust for those holders by the Company, the Trustees and each Holder of Securities and shall be binding on the Company, the Trustees and each Holder of Securities whether or not the confirmation described in Section 5.10 is requested, executed or delivered.

Section 5.08 No Set-Off

Each of the Company and the Trustees agrees, and each Holder of Securities, by its acceptance thereof, likewise agrees, that it shall have no rights of set-off or counterclaim with respect to the principal of, premium, if any, and interest on the Securities at any time when any payment of, or in respect of, such amounts to the Trustees or the Holders is prohibited by this Article 5 or is otherwise required to be paid to the holders of Senior Indebtedness or their representative or to the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, as their respective interests may appear.

Section 5.09 Amendments to Article 5

Each of the Company and the Trustees agrees, and each Holder of Securities, by its acceptance thereof, likewise agrees, not to make any changes to (i) this Article 5, (ii) the definitions of Senior Indebtedness or Senior Default, or (iii) any other provision of this Indenture that makes reference to this Article 5 or any provision of this Article 5, without the consent of each holder of Senior Indebtedness (other than trade creditors), or their representative or the trustee under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued.

Section 5.10 Authorization to Trustees to Effect Subordination

Each Holder of Securities, by its acceptance thereof, authorizes and directs the Trustees on its behalf to take such action as may be necessary or appropriate to effect the subordination provided for in this Article 5 and to acknowledge and confirm such subordination to any holder of Senior Indebtedness and appoints the Trustees its attorney-in-fact for any and all such purposes, including confirmations that the holder or holders of any Senior Indebtedness are entitled to all the rights and benefits of this Article 5 and that such holder of Senior Indebtedness may rely on and enforce each of the terms of this Indenture including, without limitation, of this Article 5. Forthwith upon the request of any holder of Senior Indebtedness or its representative or the trustee under any indenture under which any instruments evidencing any Senior Indebtedness may have been issued, the Trustees shall execute and deliver to the Person making that request a form of such confirmation or, with the advice of Counsel, any such subordination agreement, on its own behalf and on behalf of all Holders.

If an Event of Default described in clause (1), (2), (3), (4), (5), or (8) of Section 6.01 with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case, either Trustee 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 or Indexed 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 and all interest thereon to be due and payable immediately, by a notice in writing to the Company (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 specified in Section 6.01(6) or 6.01(7) occurs and is continuing, then the principal amount of all the Securities

shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustees or any Holder.

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 either Trustee as hereinafter provided in this Article, the Holders of a majority in principal amount of the Outstanding Securities of that series (or of all series, as the case may be), by written notice to the Company and the Trustees, may rescind and annul such declaration and its consequences if

(1) the Company has paid or deposited with either Trustee a sum sufficient to pay in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)),

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

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

(c) to the extent that payment of such interest is legally enforceable, interest on overdue interest at the rate or rates prescribed therefor in such Securities, and

(d) 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

(2) all Events of Default with respect to Securities of that series (or of all series, as the case may be), other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13.

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

Section 6.03 Collection of Debt and Suits for Enforcement by Trustees

The Company covenants that if

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

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

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

If the Company fails to pay such amounts forthwith upon such demand, each of the Trustees, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company 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 Company 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, either Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series (or of all series, as the case may be) by such appropriate judicial proceedings as such Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 6.04 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 Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, each Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether either Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

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

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to such Trustee and, in the event that such Trustee shall consent to the making of such payments directly to the Holders, to pay to such Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of each Trustee, its agents and counsel, and any other amounts due to such Trustee under Section 7.07.

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.

Section 6.05 Trustees May Enforce Claims Without Possession of Securities

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

Section 6.06 Application of Money Collected

Any money collected by a Trustee 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 or principal (or premium, if any) or interest, if any, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

First: to the payment of all amounts due the Trustees under Section 7.07;

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

Third: the balance, if any, to the Person or Persons entitled thereto.

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

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

Section 6.09 Restoration of Rights and Remedies

Section 6.11 Delay or Omission Not Waiver

No delay or omission of the Trustees or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

(7) If a Canadian Trustee under this Indenture is no longer required by Trust Indenture Legislation, then the Company by a Board Resolution may remove the Canadian Trustee after giving 30 days notice.

Section 7.10 Acceptance of Appointment by Successor

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

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

of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. Whenever there is a successor Trustee with respect to one or more (but less than all) series of Securities issued pursuant to this Indenture, the terms “Indenture” and “Securities” shall have the meanings specified in the provisions to the respective definitions of those terms in Section 1.01 which contemplate such situation.

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

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

Section 7.11 Merger, Conversion, Consolidation or Succession to Business

Any corporation into which either Trustee or its corporate trust business may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which either Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of either Trustee, shall be the successor of such Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by a Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. In case any of the Securities shall not have been authenticated by such predecessor Trustee, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of such Trustee; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 7.12 Appointment of Authenticating Agent

At any time when any of the Securities remain outstanding, the Trustees may appoint an Authenticating Agent or Agents, with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustees to authenticate Securities of such series and the Trustees shall give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.06. Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory

for all purposes as if authenticated by the Appropriate Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustees, and a copy of such instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustees or either Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustees by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustees by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia or the laws of Canada or any province thereof, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by U.S. federal or state or Canadian federal or provincial authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustees or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustees and to the Company. The Trustees may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustees may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.06. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Trustees agree to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustees shall be entitled to be reimbursed for such payments, subject to the provisions of Section 7.07.

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

(Certificate of Authentication may be executed by either Trustee)

Computershare Trust Company, N.A., as U.S. Trustee, certifies that this is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Section 7.13 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 individually, except to the extent the Trustees are required under Trust Indenture Legislation to perform such acts jointly, and neither Trustee shall be liable or responsible for the acts or omissions of the other Trustee. If the U.S. Trustee and Canadian Trustee are unable to agree jointly to act or refrain from acting, the Appropriate Trustee shall make the decision in accordance with its applicable legislation. Unless the context implies or requires otherwise, any written notice, request, direction, certificate, instruction, opinion or other document (each such document, a “Writing”) delivered pursuant to any provision of this Indenture to any of the U.S. Trustee or the Canadian Trustee shall be deemed for all purposes of this Indenture as delivery of such Writing to the Trustee. Each such trustee in receipt of such Writing shall notify such other trustee of its receipt of such Writing within two Business Days of such receipt provided, however, that any failure of

such trustee in receipt of such Writing to so notify such other trustee shall not be deemed as a deficiency in the delivery of such Writing to the Trustee.

Section 7.14 Other Rights of Trustees

Each Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, either Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should either Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days written notice to all parties provided (i) that such Trustee’s written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to such Trustee’s satisfaction within such 10 day period, then such resignation shall not be effective.

The parties hereto acknowledge that Canadian federal and provincial legislation addressing the protection of individuals’ personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Indenture. Despite any other provision of this Indenture, neither party shall take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Company, prior to transferring, or causing to be transferred, personal information to the Canadian Trustee, shall obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have been previously given and can be relied on or are not required under Privacy Laws. The Canadian Trustee shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Trustee agrees to (i) have designated a chief privacy officer; (ii) maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry; (iii) use personal information solely for the purposes of providing its services under or ancillary to this Indenture and not to use it for any other purpose except with the consent and direction of the Company; (iv) not sell or otherwise improperly disclose personal information to any third party; and (v) use employee administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft or unauthorized access, use or modification.

It is expressly acknowledged and agreed that the Canadian Trustee may, in the course of providing services hereunder, collect or receive, use and disclose financial and other personal information about such parties and/or their representatives, as individuals, or about other individuals related to the subject matter hereof, and use such information for the following purposes:

(i)		to provide the services required under this Indenture and other services that may be requested from time to time;

(ii)		to help the Canadian Trustee manage its servicing relationships with such individuals;

(iii)		to meet the Canadian Trustee’s legal and regulatory requirements; and

(iv)

if social insurance numbers are collected by the Canadian Trustee, to perform tax reporting and to assist in verification of an individual’s identity for security purposes.

Further, each party agrees that it shall not provide or cause to be provided to the Canadian Trustee any personal information relating to an individual who is not a party to this Indenture unless that party has assured itself that such individual understands and has consented to the aforementioned uses and disclosures. Notwithstanding anything to the contrary herein, the Company and the Trustees may, without liability, disclose information about the Holders and Beneficial Owners or Potential Holders or Beneficial Owners of the Securities pursuant to subpoena or other order issued by a court of competent jurisdiction or when otherwise required by applicable law.

Unless otherwise notified, the Trustees shall be entitled to assume that all payments have been made by the Company as required under this Indenture.

The Trustees may assume for the purposes of this Indenture that any address on the register of the Holders of the Securities is the holder’s actual address and is also determinative as to residency.

The Trustees shall have no obligation to ensure or verify compliance with any applicable laws or regulatory requirements on the issue, exercise or transfer of any Securities provided such issue, exercise or transfer, as the case may be, is effected in accordance with the terms of this Indenture. The Trustees shall be entitled to process all transfers of Securities upon the presumption that such transfers are permissible pursuant to all applicable laws and regulatory requirements. The Trustees shall have no obligation to ensure that legends appearing on the Securities certificates comply with regulatory requirements or securities laws of any applicable jurisdiction.

Except as provided in this Indenture, the Trustees shall retain the right not to act and shall not be held liable for refusing to act unless it has received clear and reasonable documentation which complies with the terms of this Indenture; such document must not require the exercise of any discretion or independent judgment.

Each Trustee hereby accepts the trusts in this Indenture declared and provided for and agrees to perform the same upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various persons who shall from time to time be holders, subject to all the terms and conditions herein set forth.

If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustees with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the U.S. Trustee, except that Bearer Securities of any series and the related coupons may be presented and surrendered for payment at the offices specified in the Security and the Company hereby appoints the same as its agents to receive such respective presentations, surrenders, notices and demands.

(5) The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for securities of any series for such purposes.

Section 11.03 Money for Securities Payments to Be Held in Trust

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities and any related coupons, it will, on or before each due date of the principal of (or premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal of (or premium, if any) or interest, if any, on Securities of such series so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustees of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities and any related coupons, it will, at least three Business Days in advance of the due date of the principal of (or premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum (in the Currency described in the preceding paragraph) sufficient to pay the principal (or premium, if any) or interest, if any, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is such Trustee) the Company will promptly notify the Trustees of its action or failure so to act.

The Company will cause each Paying Agent (other than the Trustees) 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:

(1) hold all sums held by it for the payment of the principal of (and premium, if any) and interest, if any, on Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

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

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

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustees all sums held in trust by the Company 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 Company 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 Company, in trust for the payment of the principal of (or premium, if any) or interest, if any, on any Security of any series, or any coupon appertaining thereto, and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or coupon shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustees or such Paying Agent with respect to such trust money, and all liability of the Company 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 Company 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 Company.

Section 11.04 Statement as to Compliance

The Company shall deliver to the Trustees, on or before 120 days after the end of the Company’s fiscal year, an Officers’ Certificate stating that a review of the activities of the Company during such fiscal year has been made under the supervision of the signing officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such officer signing such certificate, that the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and

is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred and is continuing, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or propose to take with respect thereto). The Company shall deliver to the Trustees upon demand evidence in such form as the Trustees may require as to compliance by the Company with any condition or covenant of the Company set out herein relating to any action required or permitted to be taken by the Company under this Indenture or as a result of any obligation imposed by this Indenture. For purposes of this Section, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

Section 11.05 Additional Amounts

If specified pursuant to Section 3.01, all payments made by or on behalf of the Company under or with respect to the Securities of any series will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other government charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Canadian Taxes”), unless the Company is required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. If the Company is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Securities, the Company will pay as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder after such withholding or deduction (including with respect to Additional Amounts) will not be less than the amount the Holder would have received if such Canadian Taxes had not been withheld or deducted; provided, however, that no Additional Amounts will be payable with respect to a payment made to a Holder (an “Excluded Holder”) if the Holder or the beneficial owner of some or all of the payment to the Holder (i) does not deal at arm’s length with the Company (for purposes of the Income Tax Act (Canada)) at the time of the making of such payment, (ii) is subject to such Canadian Taxes by reason of its failure to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes, (iii) is subject to such Canadian Taxes by reason of its being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with Canada or any province or territory thereof otherwise than by the mere holding of Securities or the receipt of payments thereunder, or (iv) is subject to such Canadian Taxes because it is not entitled to the benefit of an otherwise applicable tax treaty by reason of its legal nature. The Company will make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority as and when required in accordance with applicable law. The Company will pay all taxes, interest and other liabilities which arise by virtue of any failure of the Company to withhold, deduct and remit to the relevant authority on a timely basis the full amounts required in accordance with applicable law. The Company will furnish to the Holders, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other satisfactory evidence of such payment by the Company.

If as a result of any payment by or on behalf of the Company under or with respect to the Securities of any series, any Holder is required to pay tax under Part XIII of the Income Tax Act (Canada) or any successor provisions in circumstances where the Company is not required to make a withholding with respect to such tax (for instance, in accordance with Section 803 of the Regulations to the Income Tax Act (Canada)), then the Company will, upon demand by any such Holder, indemnify such Holder (other than a Holder (i) with which the Company does not deal at arm’s length (for the purposes of the Income Tax Act (Canada)) at the time of the making of such payment; (ii) which is subject to such Canadian Taxes by reason of its failure to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes for the payment of any such taxes, together with any interest, penalties and expenses in connection therewith, or (iii) which is subject to such Canadian Taxes because it is not entitled to the benefit of an otherwise applicable tax treaty by reason of the legal nature of such Holder). All such amounts shall be payable by the Company on demand and shall bear interest at the rate borne by the Securities, calculated from the date incurred by the Holder to the date paid by the Company. All such amounts shall be Additional Amounts for the purpose of this Indenture.

Promptly following the Company becoming aware that the Company will be obligated to pay Additional Amounts with respect to a payment hereunder, the Company will deliver to the Trustees and to any Paying Agent an Officers’ Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable. References in this Indenture to interest, principal or other payments made or to be made by the Company with respect to the Securities shall be deemed also to refer to the payment of Additional Amounts provided for in Section 3.01 that may be payable in respect thereof.

The provisions of this Section 11.05 shall survive any termination, defeasance or discharge of this Indenture.

Section 11.06 Payment of Taxes and Other Claims

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all material taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all material lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon any property or assets of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

Section 11.07 Corporate Existence

Subject to Article Nine, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if the Company shall determine that the preservation thereof is

no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 11.08 Waiver of Certain Covenants

The Company may, with respect to any series of Securities, omit in any particular instance to comply with any term, provision or condition which affects such series set forth in Section 11.06 and Section 11.07, or, as specified pursuant to Section 3.01(17) for Securities of such series, in any covenants of the Company added to this Article pursuant to Section 3.01(16) or Section 3.01(17) in connection with Securities of such series, if before the time for such compliance the Holders of at least a majority in principal amount of all Outstanding Securities of any series, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company 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.

ARTICLE TWELVE

REDEMPTION OF SECURITIES

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

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

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 3.01.

The Trustees shall promptly notify the Company 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 Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

Section 12.04 Notice of Redemption

Except as otherwise specified as contemplated by Section 3.01, notice of redemption shall be given in the manner provided for in Section 1.06 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. Failure to give notice in the manner provided in Section 1.06 to the Holder of any Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 12.06, if any,

(3) 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,

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that on the Redemption Date, the Redemption Price and accrued interest, if any, to the Redemption Date payable as provided in Section 12.06 will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(6) the Place or Places of Payment where such Securities, together in the case of Bearer Securities with all coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any,

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

(8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all coupons maturing subsequent to the Redemption Date or the amount of any such missing coupon or coupons will be deducted from the Redemption Price unless security or indemnity satisfactory to the Company, the Trustees and any Paying Agent is furnished, and

(9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on such Redemption Date pursuant to Section 3.05 or otherwise, the last date, as determined by the Company, on which such exchanges may be made.

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

Section 12.05 Deposit of Redemption Price

Section 12.06 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 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 11.02) and, unless otherwise specified as contemplated by Section 3.01, only upon presentation and surrender of coupons for such interest; and provided further that installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor

Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustees if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustees or any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 11.02) and, unless otherwise specified as contemplated by Section 3.01, only upon presentation and surrender of those coupons.

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

Section 12.07 Securities Redeemed in Part

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

Section 12.08 Tax Redemption

If specified pursuant to Section 3.01, the Securities of a series will be subject to redemption at any time, in whole but not in part, at a redemption price equal to the principal amount thereof together with accrued and unpaid interest to the date fixed for redemption, upon the giving of a notice as described below, if (1) the Company determines that (a) as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of Canada or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in position regarding application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after a date specified pursuant to Section 3.01, if any date is so specified, the Company has or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts pursuant to Section 11.05 or (b) on or after a date specified pursuant to Section 3.01, any action has been taken by any taxing authority of, or any decision has been rendered by a

court of competent jurisdiction in, Canada or any political subdivision or taxing authority thereof or therein, including any of those actions specified in (a) above, whether or not such action was taken or decision was rendered with respect to the Company, or any change, amendment, application or interpretation shall be proposed, which, in any such case, in the opinion of Counsel to the Company, will result in the Company becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any Security of such series and (2) in any such case, the Company in its business judgment determines that such obligation cannot be avoided by the use of reasonable measures available to the Company; provided, however, that (i) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which the Company would be obligated to pay such Additional Amounts were a payment in respect of the Securities then due, and (ii) at the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect.

In the event that the Company elects to redeem the Securities pursuant to the provisions set forth in the preceding paragraph, the Company shall deliver to the Trustees a certificate, signed by an authorized officer, stating that the Company is entitled to redeem the Securities pursuant to their terms.

ARTICLE THIRTEEN

SINKING FUNDS

Section 13.01 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 3.01 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 13.02. 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.

Section 13.02 Satisfaction of Sinking Fund Payments with Securities

Subject to Section 13.03, 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 Company may at its option (1) deliver to the Trustees Outstanding Securities of a series (other than any previously called for redemption) theretofore purchased or otherwise acquired by the Company together in the case of any Bearer Securities of such series with all un-matured coupons appertaining thereto, and/or (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustees by the Company or for Securities of such series which have been redeemed either at the election of the Company 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.

Section 13.03 Redemption of Securities for Sinking Fund

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company 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 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 13.02 (which Securities will, if not previously delivered, accompany such certificate) and whether the Company 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 Company 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 Company 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 13.02 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 12.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 12.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 12.06 and Section 12.07.

Prior to any sinking fund payment date, the Company shall pay to the Trustees or a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 11.03) 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.

Notwithstanding the foregoing, with respect to a sinking fund for any series of Securities, if at any time the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not exceed in the aggregate $100,000, the Trustees, unless requested by the Company, 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 Company, 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 Company) not in excess of the principal amount thereof.

ARTICLE FOURTEEN

REPAYMENT AT OPTION OF HOLDERS

Section 14.01 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 3.01 for Securities of any series) in accordance with this Article.

Section 14.02 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 Company covenants that at least three Business Days prior to the Repayment Date it will deposit with a Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 11.03) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of and (except if the Repayment Date shall be an Interest Payment Date) accrued interest, if any, on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

Section 14.03 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 Company at the Place of Payment therefor specified in the terms of such Security (or at such other place or places which the Company 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 Company.

Section 14.04 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 Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, together with all coupons, if any, appertaining thereto maturing after the Repayment Date, the principal amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 11.02) and, unless otherwise specified pursuant to Section 3.01, only upon presentation and surrender of such coupons; and provided further that, in the case of Registered Securities, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date, such Security may be paid after deducting from the amount payable therefor as provided in Section 14.02 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustees if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustees or any Paying Agent any such missing coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 11.02) and, unless otherwise specified as contemplated by Section 3.01, only upon presentation and surrender of those coupons.

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.

Section 14.05 Securities Repaid in Part

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

ARTICLE FIFTEEN

DEFEASANCE AND COVENANT DEFEASANCE

Section 15.01 Company’s Option to Effect Defeasance or Covenant Defeasance

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, the provisions of this Article shall apply to each series of Securities, and the Company may, at its option, effect defeasance (as defined below) of the Securities of or within a series under Section 15.02, or covenant defeasance (as defined below) of or within a series under Section 15.03 in accordance with the terms of such Securities and in accordance with this Article.

Section 15.02 Defeasance and Discharge

Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any related coupons on the date the conditions set forth in Section 15.04 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any related coupons, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 15.05 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 any related coupons and this Indenture insofar as such Securities and any related coupons are concerned (and the Trustees, at the expense of the Company, 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 and any related coupons to receive, solely from the trust fund described in Section 15.04 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 and any related coupons when such payments are due, (B) the Company’s obligations with respect to such Securities under Sections 3.04, 3.05, 3.06, 11.02 and 11.03 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 11.05, (C) the rights, powers, trusts, duties and immunities of the Trustees hereunder and (D) this Article. Subject to compliance with this Article, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 15.03 with respect to such Securities and any related coupons.

Section 15.03 Covenant Defeasance

Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be released from its obligations under Section 11.06 and Section 11.07, and, if specified pursuant to Section 3.01, its obligations under any other covenant, with respect to such Outstanding Securities and any related coupons on and after the date the conditions set forth in Section 15.04 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any related coupons shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such outstanding Securities and any related coupons, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under clauses (4), (5) or (9) of Section 6.01 or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and any related coupons shall be unaffected thereby.

Section 15.04 Conditions to Defeasance or Covenant Defeasance

The following shall be the conditions to application of either Section 15.02 or Section Section 15.03 to any Outstanding Securities of or within a series and any related coupons:

(1) The Company shall irrevocably have deposited or caused to be deposited with either Trustee (or another trustee satisfying the requirements of Section 7.08 who shall agree to comply with the provisions of this Article 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 and any related coupons, (A) an amount (in such Currency in which such Securities and any related coupons are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal of and premium, if any, and interest, if any, under such Securities and any related coupons, 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, if any, on such Outstanding Securities and any related coupons on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of interest, if any, (ii) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities and any related coupons on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any related coupons, and (iii)

all amounts due the Trustees under Section 7.07; provided that the Trustees shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to said payments with respect to such Securities and any related coupons. Before such a deposit, the Company may give to the Trustees, in accordance with Section 12.02 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such series and Article Tweleve hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(2) No Default or Event of Default with respect to such Securities or any related coupons shall have occurred and be continuing on the date of such deposit or, insofar as clauses (7) and (8) of Section 6.01 are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(3) 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 Company is a party or by which it is bound.

(4) In the case of an election under Section 15.02, the Company shall have delivered to the Trustees an Opinion of Counsel in the United States stating that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of execution of this Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any related coupons will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(5) In the case of an election under Section 15.03, the Company shall have delivered to the Trustees an Opinion of Counsel in the United States to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

(6) The Company shall have delivered to the Trustees an Opinion of Counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for Canadian federal, provincial or territorial income tax or other tax purposes as a result of such defeasance or covenant defeasance, as applicable, and will be subject to Canadian federal, provincial or territorial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case had such defeasance or covenant defeasance, as applicable, not occurred (and for the purposes of such

opinion, such Canadian counsel shall assume that Holders of the Securities include Holders who are not resident in Canada).

(7) The Company is not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada) on the date of such deposit or at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(8) 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 3.01.

(9) The Company 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 15.02 or the covenant defeasance under Section 15.03 (as the case may be), have been complied with.

Section 15.05 Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions

Subject to the provisions of the last paragraph of Section 11.03, all money and Government Obligations (or other property as may be provided pursuant to Section 3.01) (including the proceeds thereof) deposited with a Trustee (or other qualifying trustee, collectively, for purposes of this Section, the “Trustee”) pursuant to Section 15.04 in respect of such Outstanding Securities and any related coupons shall be held in trust and applied by such Trustee, in accordance with the provisions of such Securities and any related coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as such Trustee may determine, to the Holders of such Securities and any related coupons of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

Unless otherwise specified with respect to any Security pursuant to Section 3.01, if, after a deposit referred to in Section 15.04 has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.12(b) or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 15.04 has been made in respect of such Security, or (b) a Conversion Event occurs as contemplated in Section 3.12(d) or 3.12(e) or by the terms of any Security in respect of which the deposit pursuant to Section 15.04 has been made, the indebtedness represented by such Security and any related coupons shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and interest, if any, on such Security as they become due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on the applicable Market Exchange Rate for such Currency in effect on the third Business Day prior to each payment date, except, with respect to a Conversion Event, for such Currency in effect (as nearly as feasible) at the time of the Conversion Event.

The Company shall pay and indemnify such Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 15.04 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 and any related coupons.

Anything in this Article to the contrary notwithstanding, such Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 15.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to such Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article.

Section 15.06 Reinstatement

If a Trustee or any Paying Agent is unable to apply any money in accordance with Section 15.05 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and such Securities and any related coupons shall be revived and reinstated as though no deposit had occurred pursuant to Section 15.02 or Section 15.03, as the case may be, until such time as such Trustee or Paying Agent is permitted to apply all such money in accordance with Section 15.05; provided, however, that if the Company makes any payment of principal of (or premium, if any) or interest, if any, on any such Security or any related coupon following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities and any related coupons to receive such payment from the money held by such Trustee or Paying Agent.
