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 Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

     Any certificate or opinion of an officer of the Company or of counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of, or representations by, an accountant or firm of accountants in the employ of the Company, unless such officer or counsel, as the case may be, knows, or in the exercise of reasonable care should know, that the

certificate or opinion or representations with respect to the accounting matters upon which such certificate or opinion may be based are erroneous. Any certificate or opinion of any independent firm of public accountants filed with the Trustees shall contain a statement that such firm is independent.

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

Section 1.04 Acts of Holders

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

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

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

     (d) The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary,

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

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

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

Section 1.05 Notices, etc. to Trustees and Company

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

Section 1.06 Notice to Holders; Waiver

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

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

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

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

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

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

Section 1.07 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 1.08 Successors and Assigns

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

Section 1.09 Severability Clause

     In case any provision in this Indenture or in any Security or coupon 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.

     Nothing in this Indenture or in the Securities or coupons, express or implied, shall give to any Person, other than the parties hereto, any Authenticating Agent, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders of Securities or coupons, any benefit or any legal or equitable right, remedy or claim under this Indenture. Subject to Section 1.16, at all times in relation to this Indenture and any action to be taken hereunder, the Company and the Trustees each shall observe and comply with Trust Indenture Legislation and the Company, the Trustees and each Holder of a Security shall be entitled to the benefits of Trust Indenture Legislation.

Section 1.11 Governing Law

     This Indenture and the Securities and coupons shall be governed by and construed in accordance with the law 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. Each Trustee and the Company agrees to comply with all provisions of Trust Indenture Legislation applicable to or binding upon it in connection with this Indenture and any action to be taken hereunder. This Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions. Notwithstanding the preceding sentence, the exercise, performance or discharge by the Canadian Trustee of any of its rights, powers, duties or responsibilities hereunder shall be construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable thereto.

Section 1.12 Legal Holidays

     In any case where any Interest Payment Date, Redemption Date, sinking fund payment date or Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment or other location contemplated hereunder, then (notwithstanding any other provision of this Indenture or of any Security or coupon other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section), payment of principal (or premium, if any) or interest, if any, need not be made at such Place of Payment or other location contemplated hereunder on such date, but may be made on the next succeeding Business Day at such Place of Payment or other location contemplated hereunder with the same force and effect as if made on the Interest Payment Date or Redemption Date or sinking fund payment date, or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be.

Section 1.13 Agent for Service; Submission to Jurisdiction; Waiver of Immunities

     By the execution and delivery of this Indenture, the Company (i) acknowledges that it has irrevocably designated and appointed CT Corporation System, 111 8 ^th Avenue, 13 ^th Floor, New York, New York, 1001 as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Securities or this Indenture that may be instituted in any federal or New York State court located in The Borough of Manhattan, The City of New York, or brought by the Trustees (whether in their individual capacity or in their capacity as Trustees hereunder), (ii) submits to the non-exclusive jurisdiction of any such court in any such suit or proceeding, and (iii) agrees that service of process upon CT Corporation System and written notice of said service to the Company (mailed or delivered to the Company, attention: Chief Financial Officer, at its principal office at 1701 East “E” Street, PO Box 50850, Casper, Wyoming 82605-0850., as specified in Section 1.05 hereof), shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. The Company further agrees to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of CT Corporation System in full force and effect so long as this Indenture shall be in full force and effect.

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

     The Company irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of venue of any such action, suit or proceeding arising out of or relating to this Indenture or the Securities in any federal or state court in the State of New York, The Borough of Manhattan. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

Section 1.14 Conversion of Currency

     (a) The Company covenants and agrees that the following provisions shall apply to conversion of currency in the case of the Securities and this Indenture:

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

latest practicable date as at which liabilities of the Company may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

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

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

Section 1.16 Conflict with Trust Indenture Legislation

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

Any portion of the text of any Security may be set forth on the reverse thereof, with an appropriate reference thereto on the face of the Security.

Section 2.03 Securities Issuable in Global Form

     If Securities of or within a series are issuable in global form, as specified and contemplated by Section 3.01, then, notwithstanding clause (10) of Section 3.01, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such series from time to time endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustees in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Company Order to be delivered to the Trustees pursuant to Section 3.03 or Section 3.04. Subject to the provisions of Section 3.03 and, if applicable, Section 3.04, the Trustees shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 3.03 or Section 3.04 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or

redelivery of a Security in global form shall be in writing but need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel.

ARTICLE THREE
THE SECURITIES

Section 3.01 Amount Unlimited; Issuable in Series

     The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is unlimited.

     The Securities may be issued in one or more series and may be denominated and payable in Dollars or any Foreign Currency. The principal amount of any series of Securities may be increased and issued under this Indenture. There shall be established in one or more Board Resolutions or pursuant to authority granted by one or more Board Resolutions and, subject to Section 3.03, set forth in, or determined in the manner provided in, an Officers’ Certificate, or established in one or more indentures supplemental hereto, prior to the issuance of Securities of any series, any or all of the following, as applicable (each of which (except for the matters set forth in clauses (1), (2) and (19) below), if so provided, may be determined from time to time by the Company with respect to unissued Securities of the series and set forth in such Securities of the series when issued from time to time):

     All Securities of any one series and the coupons appertaining to any Bearer Securities of such series shall be substantially identical except, in the case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution (subject to Section 3.03) and set forth in such Officers’ Certificate or in any such indenture supplemental hereto. Not all Securities of any one series need be issued at the same time, and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series.

     If any of the terms of the series are established by action taken pursuant to one or more Board Resolutions, such Board Resolutions shall be delivered to the Trustees at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series.

Section 3.02 Denominations

     The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by Section 3.01. With respect to Securities of any series denominated in Dollars, in the absence of any such provisions, the Registered Securities of such series, other than Registered Securities issued in global form (which may be of any denomination), shall be issuable in denominations of $1,000 and any integral multiple thereof and the Bearer Securities of such series, other than the Bearer Securities issued in global form (which may be of any denomination), shall be issuable in a denomination of $5,000 and any integral multiples thereof.

Section 3.03 Execution, Authentication, Delivery and Dating

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Section 3.04 Temporary Securities

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

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

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

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

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

     Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 3.01, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to the Depositary on such Interest Payment Date upon delivery by the Depositary to the Trustees of a certificate or certificates in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established pursuant to Section

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

Section 3.05 Registration, Registration of Transfer and Exchange

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

     The Company may, subject to the consent of the Appropriate Trustee, also cause to be maintained a branch register (a “Branch Register”) or Branch Registers of Holders of Securities in accordance with Section 11.02 in the same manner and containing the same information with respect to each entry contained therein as contained in the Central Register. A copy of every entry in a Branch Register shall, promptly after the entry is made, be transmitted to the Central Security Registrar. If there is a conflict between the information contained in the Central Register and the information contained in the Branch Register, the information contained in the Central Register shall prevail. The Central Register together with each Branch Register are collectively referred to herein as the “Security Register”. At all reasonable times, the Security Register shall be open to inspection by the Trustees. The Company may appoint from time to time one or more branch security registrars (“Branch Security Registrars”) and may from time to time rescind any such appointment. The Central Security Registrar together with each Branch Security Registrar are collectively referred to herein as the “Security Registrar”.

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

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

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

     If (but only if) expressly permitted in or pursuant to the applicable Board Resolution and (subject to Section 3.03) set forth in the applicable Officers’ Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 3.01, at the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at the office of the Appropriate Trustee, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons

may be waived by the Company and the Trustees if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided , however , that, except as otherwise provided in Section 11.02, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture.

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

     Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent global Security is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as contemplated by Section 3.01 and provided that any applicable notice provided in the permanent global Security shall have been given to the Company, the Appropriate Trustee and the Common Depositary, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall deliver to the Appropriate Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Company Order with respect thereto to the Appropriate Trustee, as the Company’s agent for such purpose, to be exchanged in whole or from time to time in part, for definitive Securities without charge, and the Appropriate Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged which, unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, as specified as contemplated by Section 3.01, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof. The Appropriate Trustee shall promptly provide to the Common Depositary (or other applicable Depositary) a replacement global Security in the aggregate

principal amount of the global Security not being so exchanged. The Appropriate Trustee shall note the exchange on the register for such Securities. Notwithstanding the foregoing, no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption; and provided, further, that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

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

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

     Interests of a beneficial owner in global Securities may also be transferred or exchanged for definitive Securities if, after the occurrence of an Event of Default with respect to such Securities, and while such Event of Default is continuing, such owner notifies the Trustees in writing that it wishes to receive a Security in definitive, registered form and provides to the Trustees evidence reasonably satisfactory to the Trustees of its ownership interest in such

Securities. In such event the Company will execute, and the Appropriate Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive, registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global Security or Securities representing such series in exchange for such global Security or Securities.

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

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

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

     Any registration of transfer or exchange of Securities may be subject to service charges by the Central Securities Registrar and the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04, Section 10.06, Section 12.07 or Section 14.05 not involving any transfer.

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

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities

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

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

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

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

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

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

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

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

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

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

     (b) The provisions of this Subsection may be made applicable to any series of Securities pursuant to Section 3.01 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.01). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series may be reset by the Company on the date or dates specified on the face of such Security (each an “Optional Reset Date”). The Company may exercise such option with respect to such Security by notifying the Trustees of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date for such Security. Not later than 40 days prior to each Optional Reset Date, the Trustees shall transmit, in the manner provided for in Section 1.06, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset

Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of such Security (each such period a “Subsequent Interest Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period.

     Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Company may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or the spread or spread multiplier, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustees to transmit, in the manner provided for in Section 1.06, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable).

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

     Subject to the foregoing provisions of this Section and Section 3.05, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 3.08 Optional Extension of Stated Maturity

     The provisions
