(c) Any Officers' Certificate may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such Authorized Officer knows that the opinion with respect to the matters upon which his or her certificate may be based as aforesaid is erroneous. Any Opinion of Counsel may be based, insofar as it relates to factual matters, upon certificates, statements or opinions of, or representations by an officer or officers of the Issuer, or other persons or firms deemed appropriate by such counsel, unless such counsel knows that the certificates, statements or opinions or representations with respect to the matters upon which his or her opinion may be based as aforesaid are erroneous. (d) Any Officers' Certificate, statement or Opinion of Counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representation by an accountant (who may be an employee of the Issuer), or firm of accountants, unless such Authorized Officer or counsel, as the case may be, knows that the certificate or opinion or representation with respect to the accounting matters upon which his or her certificate, statement or opinion may be based as aforesaid is erroneous. SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. (a) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. (b) Any Officers' Certificate or Opinion of Counsel of the Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which such certificate or opinion is based is erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Issuer, stating that the information with respect to such factual matters is in the possession of such certifying entity unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters is erroneous. (c) Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 8 SECTION 104. ACTS OF HOLDERS. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and, subject to Section 601, conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section. The record of any meeting of Holders of Debt Securities shall be proved in the manner provided in Section 1406. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any manner that the Trustee deems sufficient. (c) The ownership of Debt Securities shall be proved by the Security Register. (d) If the Issuer shall solicit from the Holders of Debt Securities of any series any Act, the Issuer may, at its option, by Board Resolution, fix in advance a record date for the determination of Holders of Debt Securities entitled to take such Act, but the Issuer shall have no obligation to do so. Any such record date shall be fixed at the discretion of the Issuer. If such a record date is fixed, such Act may be sought or taken before or after the 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 purpose of determining whether Holders of the requisite proportion of Debt Securities of such series Outstanding have authorized or agreed or consented to such Act, and for that purpose the Debt Securities of such series Outstanding shall be computed as of such record date. (e) Any Act of the Holder of any Debt Security shall bind every future holder of the same Debt Security and the Holder of every Debt Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, suffered or omitted by the Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Debt Security. (f) For purposes of determining the principal amount of Outstanding Debt Securities of any series the Holders of which are required, requested or permitted to take any Act under this Indenture: (1) each Original Issue Discount Security shall be deemed to have an amount outstanding determined by the Trustee that could be declared to be due and payable pursuant to the terms of such Original Issue Discount Security as of the date such Act is delivered to the 9 Trustee and, where it is hereby expressly required, to the Issuer; and (2) each Debt Security denominated in a Foreign Currency or composite currency shall be deemed to have an amount outstanding determined by the Trustee by converting the principal amount of such Debt Security in the currency in which such Debt Security is denominated into Dollars at the Exchange Rate as of the date such Act is delivered to the Trustee and, where it is hereby expressly required, to the Issuer (or, if there is no such rate on such date for the reasons specified in Section 311(d), such rate on the date specified in such Section). SECTION 105. NOTICES, ETC., TO TRUSTEE AND ISSUER. Any Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: (1) the Trustee, by any Holder or by the Issuer, shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust & Agency Services, facsimile 201-593-6527, or such other facsimile number as may be provided by the Trustee from time to time, and shall be deemed to have been made at the time of delivery or facsimile transmission; provided that any delivery made or facsimile sent on a day other than a Business Day in New York shall be deemed to be received on the next following Business Day in New York; or (2) the Issuer, by the Trustee or by any Holder, shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing to the Issuer addressed to it at the address of its executive office specified in the first paragraph of this Indenture, Attention: Corporate Secretary, facsimile number (905) 863-8386, or such other facsimile number as may be provided by the Issuer to the Trustee from time to time, and shall be deemed to have been made at the time of delivery or facsimile transmission; provided that any delivery made or facsimile sent on a day other than a Business Day in Toronto, Ontario shall be deemed to be received on the next following Business Day in Toronto, Ontario. SECTION 106. NOTICE TO HOLDERS; WAIVER. (a) Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given to Holders if in writing and mailed, first-class postage prepaid, to each 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. (b) If the regular mail service is suspended or for any other reason it shall be impracticable to give notice to Holders by mail, then such notification to Holders as shall be made with the approval of the Trustee shall constitute sufficient notification for every purpose hereunder. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 10 (c) Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. (d) Any Act required or permitted under this Indenture shall be in the English language. SECTION 107. CONFLICT WITH TRUST INDENTURE ACT. If any provision of this Indenture limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be. SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. SECTION 109. SUCCESSORS AND ASSIGNS. All covenants and agreements in this Indenture by the Issuer shall bind its successors and assigns, whether expressed or not. All agreements of the Trustee in this Indenture shall bind its respective successors. SECTION 110. SEPARABILITY CLAUSE. If any provision in this Indenture or in the Debt Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. SECTION 111. BENEFITS OF INDENTURE. Nothing in this Indenture or in the Debt Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, and any Paying Agent and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. SECTION 112. GOVERNING LAW, ETC. (a) This Indenture and the Debt Securities shall be governed by and construed in accordance with the laws of the State of New York, but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby. 11 (b) The Issuer has appointed CT Corporation System with offices at 111 Eighth Avenue, 13th Floor, New York, New York, 10011 as its authorized agent (the "Authorized Agent") upon whom all writs, process and summonses may be served in any suit, action or proceeding arising out of or based upon this Indenture or the Debt Securities which may be instituted in any state or federal court in the City of New York, New York. The Issuer hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Issuer agrees to take any and all action, including the filing of any and all documents, that may be reasonably necessary to continue each such appointment in full force and effect as aforesaid so long as the Debt Securities remain outstanding. The Issuer agrees that the appointment of the Authorized Agent shall be irrevocable so long as any of the Debt Securities remain outstanding or until the irrevocable appointment by the Issuer of a successor agent in the City of New York, New York as its authorized agent for such purpose and the acceptance of such appointment by such successor. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Issuer. (c) The Issuer hereby: (1) agrees that any suit, action or proceeding against it arising out of or relating to this Indenture or the Debt Securities, as the case may be, may be instituted in any federal or state court sitting in the City of New York; (2) waives to the extent permitted by applicable law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding, and any claim that any suit, action or proceeding in such a court has been brought in an inconvenient forum; (3) irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding; and (4) agrees that service of process by mail to the addresses specified herein shall constitute personal service of such process on it in any such suit, action or proceeding. SECTION 113. LEGAL HOLIDAYS. If any Interest Payment Date, Redemption Date or Stated Maturity Date of any Debt Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Debt Securities) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, or Stated Maturity Date, and no interest shall accrue on such payment for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity Date, as the case may be. 12 ARTICLE TWO DEBT SECURITY FORMS SECTION 201.

The Trustee shall be entitled to receive, prior to the authentication and delivery of such Debt Securities, the supplemental indenture or the Board Resolution by or pursuant to which the terms of such Debt Securities have been approved, an Officers' Certificate as to the absence of any event that is, or after notice or lapse of time or both would become, an Event of Default, and an Opinion or Opinions of Counsel of the Issuer to the effect that: (1) all instruments furnished by the Issuer to the Trustee in connection with the authentication and delivery of such Debt Securities conform to the requirements of this Indenture and constitute sufficient authority hereunder for the Trustee to authenticate and deliver such Debt Securities; (2) the forms of such Debt Securities have been established in conformity with the provisions of this Indenture; (3) the terms of such Debt Securities have been established in conformity with the provisions of this Indenture; (4) in the event that the forms or terms of such Debt Securities have been established in a supplemental indenture, the execution and delivery of such supplemental indenture have been duly authorized by all necessary corporate action of the Issuer, such supplemental indenture has been duly executed and delivered by the Issuer and, assuming due authorization, execution and delivery by the Trustee, is a valid and binding obligation enforceable against the Issuer in accordance with its terms, subject to enforceability being limited by bankruptcy, insolvency, or other laws or foreign governmental actions affecting the enforcement of creditors' rights generally, and equitable remedies, including the remedies of specific performance and injunction, being granted only in the discretion of a court of competent jurisdiction; (5) the execution and delivery of such Debt Securities have been duly authorized by all necessary corporate action of the Issuer and such Debt Securities have been duly executed by the Issuer and, assuming due authentication by the Trustee and delivery by the Issuer, are valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, entitled to the benefit of the Indenture, subject to enforceability being limited by bankruptcy, insolvency, or other laws or foreign governmental actions affecting the enforcement of creditors' 17 rights generally, and equitable remedies, including the remedies of specific performance and injunction, being granted only in the discretion of a court of competent jurisdiction; (6) the amount of Outstanding Debt Securities of such series, together with the amount of such Debt Securities, does not exceed any limit established under the terms of this Indenture on the amount of Debt Securities of such series that may be authenticated and delivered; and (7) such other matters as the Trustee may reasonably request. (c) If the Issuer shall establish pursuant to Section 301 that the Debt Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Issuer shall execute and the Trustee shall authenticate and deliver one or more Global Securities that shall: (1) represent an aggregate amount equal to the aggregate principal amount of the Outstanding Debt Securities of such series to be represented by one or more Global Securities; (2) be registered in the name of the Depositary for such Global Security or Securities or the nominee of such Depositary; (3) be held or be delivered by the Trustee to such Depositary or pursuant to such Depositary's instruction; and (4) bear a legend substantially to the following effect: "Unless and until it is exchanged in whole or in part for the individual Debt Securities represented hereby, this Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary." (d) Each Depositary designated pursuant to Section 301 for a Global Security must, at the time of its designation and at all times while it serves as such Depositary, be a clearing agency registered under the Exchange Act and any other applicable statute or regulation. (e) The Trustee shall not be required to authenticate any Debt Securities if the issuance of such Debt Securities pursuant to this Indenture will adversely affect the Trustee's own rights, duties or immunities under this Indenture. (f) Each Debt Security shall be dated the date of its issue, except as otherwise provided pursuant to Section 301 with respect to Debt Securities of such series. (g) No Debt Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Debt Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of one of its authorized officers, and such certificate upon any Debt Security shall be conclusive evidence, and the only evidence, that such Debt Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. SECTION 304. TEMPORARY DEBT SECURITIES. (a) Pending the preparation of definitive Debt Securities of any series, the Issuer may execute, and, upon receipt of an Issuer Order, the Trustee shall authenticate and deliver, temporary Debt Securities that are printed, lithographed, typewritten, mimeographed or otherwise produced, in 18 any authorized denomination, substantially of the tenor of the definitive Debt Securities in lieu of which they are issued, in registered form, and in all cases with such appropriate insertions, omissions, substitutions and other variations as the officers of the Issuer, executing such Debt Securities may determine, as conclusively evidenced by their execution of such Debt Securities. Any such temporary Debt Securities may be in global form, representing all or a portion of the Outstanding Debt Securities of such series. Every such temporary Debt Security shall be executed by Authorized Officers of the Issuer and shall be authenticated and delivered by the Trustee upon the same terms and conditions and in substantially the same manner, and with the same effect, as the definitive Debt Securities in lieu of which it is issued. (b) If temporary Debt Securities of any series are issued, the Issuer will cause definitive Debt Securities of such series to be prepared without unreasonable delay. Upon surrender for cancellation of any one or more temporary Debt Securities of any series, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debt Securities of the same series of authorized denominations and of like tenor. Until so exchanged, temporary Debt Securities of any series shall in all respects be entitled to the same benefits under this Indenture as individual Debt Securities of such series, except as otherwise specified as contemplated by Section 301 with respect to the payment of interest on Global Securities in temporary form. (c) Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Debt Securities represented thereby pursuant to this Section 304 or Section 305, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such temporary Global Security shall be reduced for all purposes by the amount so exchanged and endorsed. SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. (a) The Issuer will maintain an office or agency at which shall be kept a register (the "Security Register") which, subject to such reasonable regulations as it may prescribe, shall provide for the registration of Debt Securities and of transfers of Debt Securities. Unless and until otherwise determined by the Issuer, the Trustee shall act as the Issuer's agent as Security Registrar and the Security Register shall be kept at the office or agency of the Trustee in the Borough of Manhattan, the City of New York. Such Security Register shall be in written form or in any other form capable of being converted into written form within a reasonable period of time. At all reasonable times, the Security Register shall be open for inspection by the Trustee. (b) Upon surrender for registration of transfer of any Debt Security of any series at the office or agency of the Issuer maintained for such purpose, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Debt Securities of the same series of any authorized denomination or denominations, of like tenor and aggregate principal amount. Every Debt Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer, the Security Registrar or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuer, the Security Registrar and the Trustee duly executed, by the Holder thereof or his attorney duly authorized in writing. 19 (c) Notwithstanding any other provision of this Section, unless and until it is exchanged in whole or in part for Debt Securities in definitive form, a Global Security representing all or a portion of the Debt Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. (d) At the option of the Holder, Debt Securities of any series (other than a Global Security) may be exchanged for other Debt Securities of the same series of any authorized denomination or denominations of a like aggregate principal amount, upon surrender of the Debt Securities to be exchanged at such office or agency. (e) If at any time the Depositary for the Debt Securities of a series notifies the Issuer that it is unwilling or unable to continue as Depositary for the Debt Securities of such series or if at any time the Depositary for the Debt Securities of such series shall no longer be eligible under Section 303(d), the Issuer shall appoint a successor Depositary with respect to the Debt Securities of such series. (f) The Issuer may at any time and in its sole discretion determine that individual Debt Securities of any series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Global Securities. In such event the Issuer will execute, and the Trustee, upon receipt of the Issuer Order for the authentication and delivery of individual Debt Securities of such series, will authenticate and deliver, individual Debt Securities of such series in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing Debt Securities of such series in exchange for such Global Security or Global Securities. (g) If specified by the Issuer pursuant to Section 301 with respect to a series of Debt Securities, the Depositary for such series of Debt Securities may surrender a Global Security for such series of Debt Securities in exchange in whole or in part for definitive Debt Securities of such series on such terms as are acceptable to the Issuer and such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver, without service charge: (1) to each Person specified by such Depositary a new definitive Debt Security or Debt Securities of the same series of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person's beneficial interest in the Global Security; and (2) to such Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of definitive Debt Securities delivered to Holders thereof. (h) In any exchange provided for in Sections 305(f) or (g), the Issuer shall execute and the Trustee will authenticate and deliver Debt Securities in registered form in authorized denominations. (i) Upon the exchange of a Global Security for individual Debt Securities in definitive form, such Global Security shall be cancelled by the Trustee. Individual Debt Securities exchanged for portions of 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 20 instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Debt Securities to the persons in whose names such Debt Securities are so registered. (j) All Debt Securities executed for delivery upon any transfer or exchange of Debt Securities shall be valid obligations of the Issuer evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered for such transfer or exchange. No service charge shall be made for any registration of transfer or exchange of Debt Securities, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer, registration of transfer or exchange of Debt Securities, other than exchanges pursuant to Sections 304, 906 or 1107 not involving any transfer. (k) The Issuer shall not be required to: (1) execute for delivery, register the transfer of or exchange of Debt Securities of any particular series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Debt Securities of such series selected for redemption under Section 1103 and ending at the close of business on the day of such mailing; or (2) register the transfer of or exchange of any Debt Security so selected for redemption in whole or in part, except the unredeemed portion of any Debt Security being redeemed in part. SECTION 306. MUTILATED, DESTROYED, LOST OR STOLEN DEBT SECURITIES. (a) If: (1) any mutilated Debt Security is surrendered to the Trustee; or (2) the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and the Issuer and the Trustee receive such security or indemnity satisfactory to them; then, in the absence of notice to the Issuer or the Trustee that such Debt Security has been acquired by a bona fide purchaser, the Issuer shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such Security, a new Debt Security of like tenor and principal amount in registered form bearing a number not contemporaneously outstanding appertaining to such destroyed, lost or stolen Debt Security. (b) If any such mutilated, destroyed, lost or stolen Debt Security has become or is about to become due and payable, the Issuer in its discretion may, instead of executing for delivery a new Debt Security, pay such Debt Security. Upon the execution for delivery of any new Debt Security under this Section, the Issuer may require the payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities. (c) Every new Debt Security of any series executed for delivery pursuant to this Section in lieu of any destroyed, lost or stolen Debt Security shall constitute a contractual obligation of the Issuer to the same effect as such destroyed, lost or stolen Debt Security and shall be at any time enforceable by anyone, and any such new Debt Security shall be entitled to all the benefits of 21 this Indenture equally and proportionately with any and all other Debt Securities of that series duly issued hereunder. SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. (a) Interest on any Debt Security that is payable on any Interest Payment Date shall be paid to the Person in whose name that Debt Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. At the option of the Issuer payment of interest on any Debt Security may be made by cheque mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer to an account designated by such Person. (b) Any interest on any Debt Security of any series that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall be paid in accordance with the following provisions and not to the registered Holder on the relevant Regular Record Date by virtue of his having been such Holder. (1) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Debt 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 Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Debt Security of such series and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Debt Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Defaulted Interest shall be paid to the Persons in whose names the Debt 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 Issuer may make payment of any Defaulted Interest on the Debt Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debt Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 22 (c) Subject to the foregoing provisions of this Section, each Debt Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Debt Security. SECTION 308. PERSONS DEEMED OWNERS. (a) Prior to due presentment of a Debt Security for registration of transfer, the Issuer, the Trustee and any agent of any of the foregoing may treat the Person in whose name such Debt Security is registered as the owner of such Debt Security for the purpose of receiving payment of principal of (and premium, if any) and, subject to Section 307, interest on such Debt Security and for all other purposes whatsoever, whether or not such Debt Security be overdue, and none of the Issuer, the Trustee or any agent of any of the foregoing shall be affected by notice to the contrary. (b) None of the Issuer, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records related to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records related to such beneficial ownership interests. SECTION 309. CANCELLATION. Unless otherwise provided, all Debt Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Issuer may deliver to the Trustee for cancellation any Debt Securities previously authenticated and delivered hereunder that the Issuer may have acquired in any manner whatsoever, and all Debt Securities so delivered shall be promptly cancelled by the Trustee. No Debt Securities shall be authenticated in lieu of or in exchange for any Debt Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Debt Securities held by the Trustee shall be disposed of in accordance with the Trustee's policy of disposal or shall be returned to the Issuer upon Issuer Request; provided, however, that the Trustee shall not be required to destroy cancelled Debt Securities. SECTION 310. COMPUTATION OF INTEREST. Except as otherwise specified pursuant to Section 301 for Debt Securities of any series, interest on the Debt Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. Solely for the purposes of disclosure pursuant to the Interest Act (Canada) and without affecting the calculation of interest on any Debt Securities, the yearly rate of interest for any portion of an interest period of less than one year is the percent rate per annum noted on any series of Debt Securities multiplied by the number of days in the calendar year in which interest is paid divided by 360. SECTION 311. PAYMENT IN CURRENCIES. (a) Payment of principal of (and premium, if any) and interest on the Debt Securities of any series shall be made in the currency or currencies specified pursuant to Section 301; provided 23 that the Holder of a Debt Security of such series may elect to receive such payment in any one of Dollars or any other currency designated for such purpose pursuant to Section 301. A Holder may make such election by delivering to the Trustee or, if the Trustee is not also acting as the Paying Agent, to any Paying Agent, a written notice thereof, substantially in the form attached hereto as Exhibit A or in such other form as may be acceptable to the Trustee or to any Paying Agent, as the case may be, not later than the close of business on the Regular or Special Record Date immediately preceding the applicable Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be. Such election shall remain in effect with respect to such Holder until such Holder delivers to the Trustee or to any Paying Agent, as the case may be, a written notice substantially in the form attached hereto as Exhibit A or in such other form as may be acceptable to the Trustee or to any Paying Agent, as the case may be, specifying a change in the currency in which such payment is to be made; provided further that any such notice must be delivered to the Trustee or to any Paying Agent, as the case may be, not later than the close of business on the Regular or Special Record Date immediately preceding the next Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, in order to be effective for the payment to be made thereon; and provided further that no such change in currency may be made with respect to payments to be made on any Debt Security with respect to which notice of redemption has been given by the Issuer, pursuant to Article Eleven. (b) Except as otherwise specified pursuant to Section 301, the Trustee or any Paying Agent, as the case may be, shall deliver to the Issuer, not later than the eighth Business Day after the Regular or Special Record Date with respect to an Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, with respect to a series of Debt Securities, a written notice specifying, in the currency or currencies in which the Debt Securities of such series are denominated, the aggregate amount of the principal of (and premium, if any) and interest on such Debt Securities to be paid on such payment date. If payments on any such Debt Securities are designated to be made in a currency other than the currency in which such Debt Securities are denominated or if at least one Holder has made the election referred to in paragraph (a) above, then such written notice shall also specify, in each currency in which payment is to be made pursuant to paragraph (a), the amount of principal of (and premium, if any) and interest on such series of Debt Securities to be paid in such currency on such payment date. (c) The Issuer shall deliver, not later than the fourth Business Day following each Regular or Special Record Date or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, to the Trustee or to any Paying Agent, as the case may be, an Exchange Rate Officers' Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Except as otherwise specified pursuant to Section 301, the amount receivable by Holders who have elected payment in a currency other than the currency in which such Debt Securities are denominated as provided in paragraph (a) above shall be determined by the Issuer on the basis of the applicable Exchange Rate set forth in the applicable Exchange Rate Officers' Certificate. (d) Except as otherwise specified pursuant to Section 301, if the Foreign Currency in which Debt Securities of a series is denominated ceases to be used both by the government of the country 24 which issued such currency and for the settlement of transactions by banks, then with respect to each date for the payment of principal of (and premium, if any) and interest on such Debt Securities occurring after the final date on which the Foreign Currency was so used, all payments with respect to such Debt Securities shall be made in Dollars; provided that payment to a Holder of a Debt Security of such series shall be made in a different Foreign Currency if that Holder has elected or elects payment in such Foreign Currency as provided for by paragraph (a) above. If payment is to be made in Dollars to the Holders of any such Debt Securities pursuant to the provisions of the preceding sentence, then the amount to be paid in Dollars on a payment date by the Issuer to the Trustee or to any Paying Agent, as the case may be, and by the Trustee or any Paying Agent to Holders shall be determined by the Trustee or by any Paying Agent, as the case may be, as of the Regular or Special Record Date with respect to such Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, and shall be equal to the sum obtained by converting the specified Foreign Currency into Dollars at the Exchange Rate on the last Record Date on which such Foreign Currency was so used in such capacity. (e) If a Holder of a Debt Security denominated in a composite currency has elected payment in a specified Foreign Currency as provided for by paragraph (a) and such Foreign Currency ceases to be used both by the government of the country which issued such currency and for the settlement of transactions by banks, such Holder shall, subject to paragraph (f) below, receive payment in such composite currency; provided that such payment to such Holder shall be made in a different Foreign Currency or in Dollars if that Holder has elected or elects payment in such Foreign Currency or in Dollars as provided for by paragraph (a) above. (f) Except as otherwise specified as contemplated by Section 301, if any composite currency in which a Debt Security is denominated or payable ceases to be used for the purposes for which it was established, then with respect to each date for the payment of principal of (and premium, if any) and interest on Debt Securities of a series denominated in such composite currency occurring after the last date on which such composite currency was so used (the "Conversion Date"), all payments with respect to such Debt Securities shall be made in Dollars; provided that payment to a Holder of a Debt Security of such series shall be made in a Foreign Currency if that Holder has elected or elects payment in such Foreign Currency as provided for by paragraph (a) above. (g) If payment with respect to Debt Securities of a series denominated in any composite currency is to be made in Dollars pursuant to the provisions of Section 311(f) then the amount to be paid in Dollars on a payment date by the Issuer to the Trustee or to any Paying Agent, as the case may be, and by the Trustee or by any Paying Agent, as the case may be, to Holders shall be determined by the Trustee or by any Paying Agent, as the case may be, as of the Regular or Special Record Date with respect to such Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, and shall be equal to the sum of the amounts obtained by converting each Component of such composite currency into Dollars at the Exchange Rate for such Component on such Record Date or fifteenth day, as the case may be, multiplied by the number of units of such composite currency that would have been so paid had such composite currency not ceased to be so used. If payment is to be made in Foreign Currency to the Holders of Debt Securities of such series pursuant to Section 311(f), then the amount to be paid in such Foreign Currency on a 25 payment date by the Issuer to the Trustee or to any Paying Agent, as the case may be, and by the Trustee or by any Paying Agent, as the case may be, to Holders shall be determined by the Trustee or by any Paying Agent, as the case may be, as of the Regular or Special Record Date with respect to such Interest Payment Date or date for payment of Defaulted Interest or the fifteenth day immediately preceding the Maturity of an installment of principal, as the case may be, and shall be determined by (1) converting each Component of such composite currency into Dollars at the Exchange Rate for such Component on such Record Date or fifteenth day, as the case may be, and (2) converting the sum in Dollars so obtained into such Foreign Currency at the Exchange Rate for such Foreign Currency on such Record Date or fifteenth day, as the case may be. (h) All decisions and determinations of the Trustee or any Paying Agent, as the case may be, regarding conversion of Foreign Currency into Dollars pursuant to Sections 311(d) or 301 or the conversion of any composite currency into Dollars or Foreign Currency pursuant to Sections 311(d) and (f) above or as specified pursuant to Section 301 or the Exchange Rate shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Issuer and all Holders of the Debt Securities. If a Foreign Currency or composite currency in which payment of Debt Securities of a series may be made ceases to be used both by the government of the country which issued such currency and for the settlement of transactions by banks, the Issuer, after learning thereof, will give notice pursuant to Section 105 thereof to the Trustee or to any Paying Agent, as the case may be, immediately (and the Trustee or any Paying Agent, as the case may be, promptly thereafter will give notice to the Holders in the manner provided in Section 106) specifying as the case may be the last date on which the Foreign Currency was used for the payment of principal of (and premium, if any) or interest on such Debt Securities, or the Conversion Date with respect to such composite currency and the Components of such composite currency on such Conversion Date. If any Component subsequently changes, the Issuer, after learning thereof, will give notice to the Trustee or to any Paying Agent, as the case may be, similarly. The Trustee or any Paying Agent, as the case may be, shall be fully justified, protected and otherwise held harmless in relying and acting upon the information so received by the Issuer and shall not otherwise have any duty or obligation to determine or verify such information independently. SECTION 312. JUDGMENTS. Any payment in respect of principal of (and premium, if any) and interest otherwise due on Debt Securities made in Canadian currency by the Issuer to any Holder of Debt Securities (the "Payee") pursuant to a judgment or order of a court or tribunal in Canada shall constitute a discharge of the Issuer only to the extent of the amount of Dollars or Foreign Currency payable on such Debt Securities (the "Purchased Amount") that the Payee, on the date of such payment in Canadian currency, would be able to purchase with the amount so paid based on the noon buying rate for Dollars or the Foreign Currency for wire transfers quoted on the date of payment or, if such date is not a Business Day in Toronto, Ontario, on the next Business Day in Toronto, Ontario. If the amount otherwise due to the Payee (the "Amount Due") is greater or less than the Purchased Amount, the Issuer shall indemnify and hold harmless the Payee to the extent that the Amount Due exceeds the Purchased Amount and the Issuer may retain the amount, if any, by which the Amount Due is less than the Purchased Amount. This indemnity shall constitute a separate and independent obligation from the other obligations contained in this Indenture and 26 shall give rise to a separate and independent cause of action and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of amounts due under the Debt Securities or any judgment or order. SECTION 313. CUSIP NUMBERS. The Issuer in issuing the Debt Securities may use "CUSIP" numbers (if then generally accepted in use), and if so, the Trustee shall use "CUSIP" numbers in notices and redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Debt Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Debt Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the "CUSIP" numbers. ARTICLE FOUR SATISFACTION AND DISCHARGE SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE. (a) This Indenture shall upon Issuer Request cease to be of further effect as to the Issuer (except as to any surviving rights of registration of transfer or exchange of Debt Securities provided for herein and rights to receive payments of principal of (and premium, if any) and interest thereon) and the Trustee, at the expense of the Issuer, shall execute proper instruments provided to it acknowledging satisfaction and discharge of this Indenture with respect to the Issuer, when: (1) either (i) all Debt Securities theretofore issued by the Issuer and authenticated and delivered hereunder (other than: (x) Debt Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 306; and (y) Debt Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (ii) all such Debt Securities issued by the Issuer and authenticated and delivered hereunder and not theretofore delivered to the Trustee for cancellation: (x) have become due and payable; (y) will become due and payable at their Stated Maturity Date within one year; or 27 (z) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Issuer, and the Issuer, in the case of (ii)(x), (ii)(y) or (ii)(z) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust an amount sufficient to pay and discharge the entire indebtedness on such Debt Securities for principal (and premium, if any) and interest to the date of such deposit (in the case of Debt Securities that have become due and payable) or to the Stated Maturity Date or Redemption Date, as the case may be; (2) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer; and (3) the Issuer has delivered to the Trustee an Officers' Certificate and Opinion of Counsel each stating that all conditions precedent herein provided related to the satisfaction and discharge of this Indenture have been complied with. (b) Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Issuer to the Trustee under Section 606 and, if money shall have been deposited with the Trustee pursuant to paragraph (a)(1)(ii) of this Section, the obligations of the Trustee under Section 402 and Section 1003(e) shall survive such satisfaction and discharge. SECTION 402. APPLICATION OF TRUST MONEY. Subject to the provisions of Section 1003(e), all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Debt Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. ARTICLE FIVE DEFAULTS AND REMEDIES SECTION 501. EVENTS OF DEFAULT AND ENFORCEMENT. (a) If and when any one or more of the following events (herein called an "Event of Default") shall happen and be continuing with respect to the Debt Securities of any series, namely: (1) a default in payment of principal (and premium, if any) of any Debt Security of such series when due; (2) a default in payment of interest on any Debt Security of such series when due and payable and the continuance of such default for 30 days; 28 (3) a default in the deposit of any sinking fund payment on any Debt Security of such series when due and the continuance of such default for 30 days; (4) a default in performing or observing any of the covenants, agreements or other obligations of the Issuer, as described herein for 90 days after written notice to the Issuer by the holders of not less than 25% in principal amount of Outstanding Debt Securities of such series requiring the same to be remedied; (5) a decree, judgment, or order by a court having jurisdiction in the premises shall have been entered adjudging the Issuer a bankrupt or insolvent or approving as properly filed a petition seeking reorganization, readjustment, arrangement, composition or similar relief for the Issuer under any bankruptcy, insolvency or other similar applicable law and such decree, judgment or order of a court having jurisdiction in the premises for the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of the Issuer of a substantial part of its property, or for the winding up or liquidation of its affairs, shall have remained in force for a period of 60 consecutive days; or any substantial part of the property of the Issuer shall be sequestered or attached and shall not be returned to the possession of the Issuer or released from such attachment whether by filing of a bond, or stay or otherwise within 60 consecutive days thereafter; (6) the Issuer shall institute proceedings to be adjudicated a voluntary bankrupt, or shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking reorganization, readjustment, arrangement, composition or similar relief under any bankruptcy, insolvency or other similar applicable law or the Issuer shall consent to the filing of any such petition, or shall consent to the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency for it or of a substantial part of its property, or shall make an assignment for the benefit of creditors, or shall be unable, or admit in writing its inability, to pay its debts generally as they become due, or corporate action shall be taken by the Issuer in furtherance of any of the aforesaid actions; (7) the occurrence of an event of default as defined in any evidence of indebtedness for borrowed money of the Issuer exceeding on its face $100,000,000 in principal amount, whether such indebtedness now exists or shall hereafter be created, which results in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable and such acceleration shall not be rescinded or annulled within 10 days after written notice (i) specifying such default, (ii) requiring such defaulting entity to cause such acceleration to be rescinded or annulled, and (iii) stating that such notice is a "Notice of Default" thereunder, shall have been given to such defaulting entity by the Trustee or to such defaulting entity and the Trustee by the trustee under any such lien, indenture or instrument, by the holder or holders of any such indebtedness or by the agent of any such holder or holders; or (8) any other Event of Default provided with respect to the Debt Securities of that series; 29 then, and in each and every such case, the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of such series at such time may declare the principal of (and premium, if any) together with accrued interest on, all such Debt Securities of such series to be due and payable immediately, by a notice in writing to the Issuer and to the Trustee if given by the Holders, and upon any such declaration such principal amount (and premium, if any) together with accrued interest thereon, shall become immediately due and payable. SECTION 502. WAIVER OF DECLARATION. At any time after such a declaration of acceleration with respect to the Debt Securities of a series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided, the Holders of a majority in principal amount of Outstanding Debt Securities of such series, by written notice to the Issuer and the Trustee, may rescind and annul such declaration and its consequences if: (1) the Issuer has paid or deposited with the Trustee a sum sufficient to pay: (i) all overdue interest on all the Debt Securities of such series; (ii) the principal of any of the Debt Securities of such series which have become due otherwise than by such declaration of acceleration, and interest thereon at the rate or rates prescribed therefor in such Debt Securities; and (iii) to the extent that payment of such interest is lawful and applicable, interest upon overdue installments of interest at the rate or rates prescribed therefor in such Debt Securities; and (2) all Events of Default with respect to the Debt Securities of such series, other than the non-payment of the principal of, and interest on, such Debt Securities which have become due solely by such declaration of acceleration, have been cured or waived in accordance with the provisions of the Indenture. SECTION 503. WAIVER. (a) The Holders of not less than a majority in principal amount of the Outstanding Debt Securities of any series may on behalf of the Holders of all Debt Securities of any such series waive any past or existing default hereunder with respect to such series and its consequences, except a default: (1) in the payment of the principal of (or premium, if any) or interest on any Debt Security of such series; or (2) in respect of a covenant or provision hereof that under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Debt Security of such series affected. 30 (b) Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 504. OTHER REMEDIES. (a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of (and premium, if any) or interest on Debt Securities or to enforce the performance of any provision of Debt Securities or this Indenture. (b) The Trustee may maintain a proceeding even if it does not possess any Debt Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies, except as provided in Section 306, are cumulative to the extent permitted by law. SECTION 505. APPLICATION OF MONEY COLLECTED. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the dates fixed by the Trustee and, in case of the distribution of such money on account of principal of (and premium, if any) or interest, upon presentation of Debt Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 606; SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on Debt Securities, in respect of which or for the benefit of which such money has been collected ratably, without preference or priority of any kind, according to the amounts due and payable on such Debt Securities for principal (and premium, if any) and interest, respectively. The Holders of any Debt Securities denominated in a composite currency or a Foreign Currency shall be entitled to receive a ratable portion of the amount determined by the Trustee converting the principal amount Outstanding of such Debt Securities and matured but unpaid interest on such Debt Securities in the currency in which such Debt Securities are denominated into Dollars at the Exchange Rate as of the date of declaration of acceleration of the Maturity of the Debt Securities (or, if there is no such rate on such date for the reasons specified in Section 311(d), such rate on the date specified in such Section); and THIRD: To the Issuer. SECTION 506. CONTROL BY HOLDERS. (a) The Holders of at least a majority in principal amount of the Outstanding Debt Securities of any series, may: 31 (1) direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Debt Securities of such series; and (2) take any other action authorized to be taken by or on behalf of the Holders of any specified aggregate principal amount of Debt Securities under any provisions of this Indenture or under applicable law. (b) The Trustee may refuse, however, to follow any direction that conflicts with law or this Indenture or is unduly prejudicial to the rights of other Holders. SECTION 507. LIMITATION ON SUITS. (a) A Holder of Debt Securities may pursue a remedy with respect to this Indenture directly himself only if: (1) the Holder gives to the Trustee written notice of a continuing Event of Default; (2) the Holders of at least 25% in principal amount of all of the then Outstanding Debt Securities issued under the Indenture (treated as a class) make a request in writing to the Trustee to pursue the remedy; (3) such Holder or Holders indemnify the Trustee in form satisfactory to it against any loss, liability, claim, damage or expense; (4) the Trustee does not comply with the request within 60 days after receipt of such request and indemnity; and (5) during such 60-day period the Holders of a majority in principal amount of all of the Outstanding Debt Securities (treated as a class) do not give the Trustee a direction inconsistent with the request. (b) Holders may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. SECTION 508. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of (and, premium, if any) and interest on Debt Securities held by him, on or after the respective due dates expressed in the Debt Securities (or, in the case of redemption, on the Redemption Date), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. SECTION 509. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 501(1), (2) or (3) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal (and premium, if any) and interest remaining unpaid. SECTION 510. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses, disbursements and advances of the Trustee) and the Holders allowed in any judicial proceedings relative to the Issuer, its creditors or its property. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or compensation 32 affecting the Debt Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 511. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 507, or a suit by any Holder or group of Holders of more than 10% in principal amount of the Outstanding Debt Securities. SECTION 512. DELAY OR OMISSION NOT WAIVER. No delay or omission of the Trustee or of any Holder of any Debt Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 513. WAIVER OF STAY OR EXTENSION LAWS. The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so), hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX THE TRUSTEE SECTION 601. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of an Event of Default: 33 (1) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others shall be inferred or implied; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; however, the Trustee shall examine the certificates and opinions required to be delivered to it pursuant to the terms of this Indenture to determine whether or not they so conform. (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (1) this paragraph does not limit the effect of paragraph (b) of this Section; (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; (3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 506; and (4) no provision of the Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (d) Every provision of this Indenture that in any way relates to the Trustee is subject to the above paragraphs of this Section. The Trustee may refuse to perform any duty or exercise any right or power under this Indenture (including with respect to Section 506) unless it receives indemnity reasonably satisfactory to it for actions taken under this Indenture. The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 602. RIGHTS OF TRUSTEE. The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person or persons. The Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. Any request, direction, order or demand of the Issuer mentioned herein shall be sufficiently evidenced by an 34 Officers' Certificate (unless other evidence in respect thereof is herein specifically prescribed). Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance thereon. The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through the appointment of a co-trustee or through agents, attorneys, custodians or nominees and shall not be responsible for the misconduct or negligence of any agent, attorney, custodian or nominee appointed with due care. The Trustee shall not be liable for any action it takes or omits to take in good faith without negligence or willful misconduct, except as otherwise provided in this Indenture, which it reasonably believes to be authorized or within its rights or powers. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. SECTION 603. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual or any other capacity may become the owner or pledgee of Debt Securities and may otherwise deal with the Issuer with the same rights it would have if it were not Trustee. Any agent of the Trustee may do the same with like rights. However, the Trustee is at all times subject to Sections 609 and 610. SECTION 604. TRUSTEE'S DISCLAIMER. The Trustee makes no representation as to the validity or adequacy of Debt Securities, it shall not be accountable for the Issuer's use of the proceeds from Debt Securities, and it shall not be responsible for any statement in Debt Securities other than its certificate of authentication. SECTION 605. NOTICE OF DEFAULTS. (a) If an Event of Default with respect to a series of Debt Securities occurs and is continuing, the Trustee shall mail to Holders of Debt Securities of such series a notice of the Event of Default within 90 days after it occurs. Except in the case of an Event of Default resulting from nonpayment on any Debt Securities, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of Debt Securities. (b) Except in the case of an Event of Default resulting from nonpayment on any Debt Security the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Debt Securities and this Indenture. SECTION 606. COMPENSATION AND INDEMNITY. (a) The Issuer shall pay to the Trustee from time to time compensation for its services as agreed separately by the Issuer and the Trustee. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. 35 (b) The Issuer shall fully indemnify the Trustee and any predecessor Trustee and their agents for, and hold them harmless against, any and all loss, damage, claims, liability or expense (including reasonable attorneys' fees and expenses) arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent that such loss, damage, claim, liability or expense is caused by its own negligence or bad faith or, with respect to indemnification of an agent hereunder, the negligence or bad faith of such agent. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. The Issuer shall defend the claim and the Trustee shall cooperate in the defense. The Issuer need not pay for any settlement made without its consent. (c) Except as otherwise expressly provided herein, the Issuer agrees to reimburse the Trustee upon its request for all reasonable and documented expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable and documented compensation, expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith or, with respect to documented compensation, expenses and disbursements of an agent or attorney, the negligence or bad faith of such agent or attorney. (d) To secure the Issuer's payment obligations in this Section, the Trustee shall have a lien prior to Debt Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on Debt Securities. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(5) or Section 501(6), the reasonable and documented expenses (including the reasonable and documented charges and expenses of its counsel) and compensation for the services are intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law. The provisions of this Section shall survive the termination of this Indenture and the resignation or removal of the Trustee. SECTION 607. REPLACEMENT OF TRUSTEE. (a) A resignation or removal of the Trustee and appointment of a successor Trustee for the Debt Securities of any series shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. (b) The Trustee may resign at any time with respect to Debt Securities of one or more series by giving written notice thereof to the Issuer. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee and to the Issuer within 30 days after the giving of such notice of resignation, the resigning Trustee may at the expense of the Issuer petition any court of competent jurisdiction for the appointment of a successor Trustee to the Trustee. The Holders of at least a majority in principal amount of then Outstanding Debt Securities of such series may remove the Trustee by so notifying the Trustee and the Issuer in writing if: (1) the Trustee fails to comply with Section 609; (2) the Trustee is adjudged a bankrupt or an insolvent; 36 (3) a receiver or public officer takes charge of the Trustee or its property; or (4) the Trustee becomes incapable of acting; in addition, in any such case, (i) the Issuer by a Board Resolution thereof may remove the Trustee with respect to all Debt Securities, or (ii) any Holder who has been a bona fide Holder of a Debt Security of any series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee for the Debt Securities of such series and the appointment of a successor Trustee. (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason with respect to the Debt Securities of one or more series, the Issuer shall promptly appoint a successor Trustee or Trustees with respect to the Debt Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Debt Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Debt Securities of any particular series) and shall comply with the applicable requirements of this Section 607. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of Outstanding Debt Securities of any series may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer with respect to the Debt Securities of such series. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount of the Debt Securities of any series may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debt Securities of such series. (d) If the Trustee fails to comply with Section 609, any Holder of Debt Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. (e) The Issuer shall give notice of each resignation and each removal of the Trustee with respect to Debt Securities of any series and each appointment of a successor Trustee with respect to Debt Securities of any series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to Debt Securities of such series and the address of its Corporate Trust Office. (f) In the case of an appointment hereunder of a successor Trustee with respect to all Debt Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Issuer 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 request of the Issuer 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. (g) In case of the appointment hereunder of a successor Trustee with respect to Debt Securities of one or more (but not all) series, the Issuer, the retiring Trustee upon payment of its charges and each successor Trustee with respect to Debt Securities of one or more series shall execute 37 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 Debt 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 Debt 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 Debt 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 Debt Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Issuer 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 Debt Securities of that or those series to which the appointment of such successor Trustee relates. (h) Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (f) or (g) of this Section, as the case may be. (i) 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 608. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee, provided that prior written notice thereof is given to the Issuer and such successor corporation is acceptable to the Issuer. SECTION 609. ELIGIBILITY; DISQUALIFICATION. This Indenture shall always have a Trustee who satisfies the requirements of Section 310(a)(1) of the Trust Indenture Act. The Trustee shall always have a combined capital and surplus of at least $5 million, calculated as permitted by Section 310(a)(2) of the Trust Indenture Act. The Trustee is subject to Section 310(b) of the Trust Indenture Act, including the optional provision permitted by the second sentence of Section 310(b)(9) of the Trust Indenture Act. 38 SECTION 610. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE ISSUER. The Trustee is subject to Section 311(a) of the Trust Indenture Act, except with respect to any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed is subject to Section 311(a) of the Trust Indenture Act to the extent indicated. ARTICLE SEVEN HOLDERS' LISTS AND REPORTS BY TRUSTEE AND ISSUER SECTION 701. PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders of Debt Securities received by the Trustee in its capacity as Security Registrar, if so acting. (b) If three or more Holders of a series of Debt Securities (hereinafter referred to as "applicants") apply in writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Debt Security for a period of at least six months immediately preceding the date of such application, and such application states that the applicants' desire to communicate with other Holders of Debt Securities of a particular series (in which case the applicants must hold Debt Securities of such series) or with all Holders of Debt Securities with respect to their rights under this Indenture or under the Debt Securities and is accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the Trustee shall, within five Business Days after the receipt of such application, at its election, either: (1) afford such applicants access to the information preserved at the time by the Trustee in accordance with Section 701(a); or (2) inform such applicants as to the approximate number of Holders of Debt Securities of such series or of all Debt Securities, as the case may be, whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 701(a), and as to the approximate cost of mailing to such Holders the form of proxy or other communication, if any, specified in such application. If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Holder whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 701(a), a copy of the form of proxy or other communication that is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender, the Trustee shall mail to such applicants and file with the Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the Holders or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the 39 Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the entry of such order and the renewal of such tender, otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application. (c) Every Holder of Debt Securities, by receiving and holding the same, agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Section 701(b), regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under Section 701(b).

(b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates). (c) The Issuer shall also comply with the provisions of Section 314(a) of the Trust Indenture Act. ARTICLE EIGHT AMALGAMATION, MERGER, CONVEYANCE, TRANSFER OR LEASE SECTION 801. AMALGAMATION AND MERGER OF ISSUER AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS. So long as any Debt Security of a particular series remains Outstanding, the Issuer will not amalgamate or merge with any other corporation or enter into any reorganization or arrangement or effect any conveyance, transfer or lease of all or substantially all of the assets of it and its Subsidiaries, taken as a whole (other than with or to Nortel Networks Limited, provided that Nortel Networks Limited will assume all obligations as successor issuer under this Indenture or the Issuer shall be the surviving corporation or one of the continuing corporations), unless in any such case: (1) (a) the Issuer shall be the surviving corporation or one of the continuing corporations, or (b) the successor corporation (or the Person that leases or that acquires by conveyance or transfer all or substantially all of the assets of the Issuer and its Subsidiaries, taken as a whole) shall expressly assume the due and punctual payment of the principal of (and premium, if any) and interest on all Outstanding Debt Securities issued hereunder, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Issuer by supplemental indenture pursuant to Article Nine satisfactory to the Trustee, executed and delivered to the Trustee by such corporation; and (2) the Issuer or the successor corporation shall not, immediately thereafter be in default under this Indenture or the Debt Securities. SECTION 802. RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.

Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of the Issuer any or all of Debt Securities of any series issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee. All Debt Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as Debt Securities theretofore or thereafter issued or endorsed in accordance with the terms of this Indenture as though all of such Debt Securities had been issued or endorsed at the date of the execution hereof. (b) In the case of any such amalgamation, merger, reorganization, arrangement, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in Debt Securities thereafter to be issued as may be appropriate. SECTION 803. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL. The Trustee shall receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any such amalgamation, merger, reorganization, arrangement, conveyance, transfer or lease, and any such assumption, comply with the provisions of this Article Eight.
