Section 2.04 Execution of Debt Securities. The Debt Securities shall be signed (either manually or by facsimile or other electronic signature) by any two authorized directors or officers of the Company holding office at the time of signing. Such signatures upon the Debt Securities may be the manual, facsimile or other electronic signatures of the present or any future such authorized officers and may be imprinted or otherwise reproduced on the Debt Securities.

Only such Debt Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed (either manually or by facsimile or other electronic signature) by the Appropriate Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Appropriate Trustee upon any Debt Security executed by the Company shall be conclusive evidence that the Debt Security so authenticated has been duly authenticated and delivered hereunder.

In case any officer of the Company who shall have signed any of the Debt Securities shall cease to be such officer before the Debt Securities so signed shall have been authenticated and delivered by the Appropriate Trustee, or disposed of by the Company, such Debt Securities nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Debt Securities had not ceased to be such officer of the Company; and any Debt Security may be signed on behalf of the Company by such Persons as, at the actual date of the execution of such Debt Security, shall be the proper officers of the Company, although at the date of such Debt Security or of the execution of this Indenture any such Person was not such officer.

Section 2.05 Authentication and Delivery of Debt Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debt Securities of any series executed by the Company to the Appropriate Trustee for authentication, and the Appropriate Trustee shall thereupon authenticate and deliver said Debt Securities to or upon a Company Order. In authenticating such Debt Securities, and accepting the additional responsibilities under this Indenture in relation to such Debt Securities, the Appropriate Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon:

(a) a copy of any resolution or resolutions of the Board of Directors, certified by any authorized officer of the Company, authorizing the terms of issuance of any series of Debt Securities;

(b) an executed supplemental Indenture, if any;

(c) an Officers’ Certificate or an officer’s authentication order specifying the amount of the Debt Securities to be authenticated, the date of original issue thereof, the name of the Holder for such issuance, and any relevant delivery instructions; and

(d) an Opinion of Counsel prepared in accordance with Section 13.05 which shall also state:

(i) that the form of such Debt Securities has been established by or pursuant to a resolution of the Board of Directors or by a supplemental Indenture as permitted by Section 2.01 in conformity with the provisions of this Indenture;

(ii) that the terms of such Debt Securities have been established by or pursuant to a resolution of the Board of Directors or by a supplemental Indenture as permitted by Section 2.03 in conformity with the provisions of this Indenture;

(iii) that such Debt Securities, when authenticated and delivered by the Appropriate Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms except for customary exceptions, including that (A) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally and (B) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability;

(iv) that the Company has the corporate power to issue such Debt Securities and has duly taken all necessary corporate action with respect to such issuance;

(v) that the issuance of such Debt Securities will not contravene the articles or by-laws of the Company or result in any material 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;

(vi) that authentication and delivery of such Debt Securities and the execution and delivery of any supplemental Indenture will not violate the terms of this Indenture; and

(vii) such other matters as the Appropriate Trustee may reasonably request.

Such Opinion of Counsel need express no opinion as to whether a court in Canada or the United States would render a money judgment in a currency other than that of Canada or the United States, respectively.

The Appropriate Trustee shall have the right to decline to authenticate and deliver any Debt Securities under this Section 2.05 if the Appropriate Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Appropriate Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of directors, trustees or vice presidents shall determine that such action would expose the Appropriate Trustee to personal liability to existing Holders.

The Appropriate Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate Debt Securities of any series. Unless limited by the terms of such appointment, an authenticating agent may authenticate Debt Securities whenever the Appropriate Trustee may do so. Each reference in this Indenture to authentication by the Appropriate Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, paying agent or agent for service of notices and demands. Each authenticating agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any state thereof or the District of Columbia or the laws of Canada or any province thereof, authorized under such laws to act as authenticating agent, having a combined capital and surplus of not less than $10,000,000 and subject to supervision or examination by Canadian federal or provincial or United States federal or state authority.

Unless otherwise provided in the form of Debt Security for any series, each Debt Security shall be dated the date of its authentication.

Section 2.06 Denomination of Debt Securities. Unless otherwise provided in the form of Debt Security for any series, in a resolution of the Board of Directors and set forth in an Officers’ Certificate, or in any supplement to the Indenture applicable thereto, the Debt Securities of each series shall be issuable only in such denominations as shall be specified or contemplated by Section 2.03. In the absence of any such specification with respect to the Debt Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 2.07 Registration of Transfer and Exchange.

(a) The Company shall keep or cause to be kept a register for each series of Debt Securities issued hereunder (hereinafter collectively referred to as the “Debt Security Register”), in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Debt Securities and the transfer of Debt Securities as in this Article II provided. At all reasonable times the Debt Security Register shall be open for inspection by the Trustees. Subject to Section 2.15, upon due presentment for registration of transfer of any Debt Security at any office or agency to be maintained by the Company in accordance with the provisions of Section 4.02, the Company shall execute and the Appropriate Trustee shall authenticate and deliver in the name of the transferee or transferees a new Debt Security or Debt Securities of authorized denominations for a like aggregate principal amount.

Unless and until otherwise determined by the Company by resolution of the Board of Directors or pursuant to Section 2.03, the Company hereby appoints the Canadian Trustee as the Registrar and transfer agent for the Debt Securities.

Debt Securities of any series (other than a Global Security, except as set forth below) may be exchanged for a like aggregate principal amount of Debt Securities of the same series of other authorized denominations. Subject to Section 2.15, Debt Securities to be exchanged shall be surrendered at the office or agency to be maintained by the Company as provided in Section 4.02, and the Company shall execute and the Appropriate Trustee shall authenticate and deliver in exchange therefor the Debt Security or Debt Securities which the Holder making the exchange shall be entitled to receive.

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

Each Debt 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 rules and regulations of U.S. securities laws and the Securities Transfer Association of Canada, as applicable.

(b) All Debt Securities presented or surrendered for registration of transfer, exchange or payment shall (if so required by the Company, the Appropriate Trustee or the Registrar) be duly endorsed or be accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, the Appropriate Trustee and the Registrar, duly executed by the Holder or its attorney duly authorized in writing.

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

No service charge shall be made for any exchange or registration of transfer of Debt Securities (except as provided by Section 2.09), but the Company may require payment of a sum sufficient to cover any tax, fee, assessment or other governmental charge that may be imposed in relation thereto, other than those expressly provided in this Indenture to be made at the Company’s own expense or without expense or without charge to the Holders.

The Company shall not be required (i) to issue, register the transfer of or exchange any Debt Securities for a period of 15 days next preceding any mailing of notice of redemption of Debt Securities of such series or (ii) to register the transfer of or exchange any Debt Securities selected, called or being called for redemption, from the date of mailing of the notice of redemption up to the redemption date for such Debt Securities.

Prior to the due presentation for registration of transfer of any Debt Security, the Company, the Appropriate Trustee, any paying agent or any Registrar may deem and treat the Person in whose name a Debt Security is registered as the absolute owner of such Debt Security for the purpose of receiving payment of principal of, and premium, if any, and (subject to Section 2.12 and 2.17) interest on, such Debt Security and for all other purposes whatsoever, whether or not such Debt Security is overdue, and none of the Company, the Appropriate Trustee, any paying agent or Registrar shall be affected by notice to the contrary.

None of the Company, the Trustees, any agent of the Trustees, any paying agent or any Registrar will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The Trustees, Registrars and any transfer agents shall not have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer or exchange imposed under this Indenture or under applicable law with respect to any transfer or exchange of any interest in any Debt Security (including any transfers between or among participants or other beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.08 Temporary Debt Securities. Pending the preparation of definitive Debt Securities of any series, the Company may execute and the Appropriate Trustee shall authenticate and deliver temporary Debt Securities (printed, lithographed, photocopied, typewritten or otherwise produced) of any authorized denomination, and substantially in the form of the definitive Debt Securities in lieu of which they are issued, in registered form, and with such omissions, insertions and variations as may be appropriate for temporary Debt Securities, all as may be determined by the Company with the concurrence of the Appropriate Trustee. Temporary Debt Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary Debt Security shall be executed by the Company and be authenticated by the Appropriate Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Debt Securities.

If temporary Debt Securities of any series are issued, the Company will cause definitive Debt Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be exchangeable for definitive Debt Securities of such series upon surrender of the temporary Debt Securities of such series at the office or agency of the Company at a Place of Payment for such series, without charge to the Holder thereof, and upon surrender for cancellation of any one or more temporary Debt Securities of any series, the Company shall execute and the Appropriate 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 definitive Debt Securities of such series.

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 Section 2.07 or this Section 2.08, the temporary Global Security shall be endorsed by the Appropriate 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 to be exchanged and endorsed.

Section 2.09 Mutilated, Destroyed, Lost or Stolen Debt Securities. If (a) any mutilated Debt Security is surrendered to the Appropriate Trustee at its corporate trust office or (b) the Company and the Appropriate Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and there is delivered to the Company and the Appropriate Trustee such security (or surety bond in the case of the Canadian Trustee) or indemnity as may be required by them to save each of them and any paying agent harmless, and neither the Company nor the Appropriate Trustee receives notice that such Debt Security has been acquired by a bona fide purchaser, then the Company shall execute and, upon a Company Order, the Appropriate Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt Security of the same series of like tenor, form, terms and principal amount, bearing a number not contemporaneously Outstanding. Upon the issuance of any substituted Debt Security pursuant to this Section 2.09, the Company may require the payment of a sum sufficient to cover any tax, fee, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security which has matured or is about to mature or which has been called for redemption shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substituted Debt Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debt Security) if the applicant for such payment shall furnish the Company and the Appropriate Trustee with such security, surety bond or indemnity as either may require to save it harmless from all risk, however remote, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Appropriate Trustee of the destruction, loss or theft of such Debt Security and of the ownership thereof.

Every substituted Debt Security of any series issued pursuant to the provisions of this Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost or stolen shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of that series duly issued hereunder. All Debt Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities, and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

Section 2.10 Cancellation of Surrendered Debt Securities. All Debt Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to the Company or to any paying agent or a Registrar or to a Trustee who is not the Appropriate Trustee, be delivered to the Appropriate Trustee for cancellation by it, or if surrendered to the Appropriate Trustee, shall be canceled by it, and no Debt Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All canceled Debt Securities held by the Appropriate Trustee shall be destroyed (subject to the record retention requirements of the Exchange Act) and certification of their destruction delivered to the Company, unless otherwise directed. On request of the Company, the Appropriate Trustee shall deliver to the Company canceled Debt Securities held by such Trustee. If the Company shall acquire any of the Debt Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented thereby unless and until the same are delivered or surrendered to the Appropriate Trustee for cancellation. The Company may not issue new Debt Securities to replace Debt Securities it has redeemed, paid or delivered to the Appropriate Trustee for cancellation.

Section 2.11 Provisions of the Indenture and Debt Securities for the Sole Benefit of the Parties and the Holders. Nothing in this Indenture or in the Debt Securities, expressed or implied, shall give or be construed to give to any Person, other than the parties hereto, the Holders or any Registrar or paying agent, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all its covenants, conditions and provisions being for the sole benefit of the parties hereto, the Holders and any Registrar and paying agents.

Section 2.12 Payment of Interest; Interest Rights Preserved.

(a) Interest on any Debt Security that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the Person in whose name such Debt Security is registered at the close of business on the regular record date for such interest notwithstanding the cancellation of such Debt Security upon any transfer or exchange subsequent to the regular record date. Payment of interest on Debt Securities shall be made at the corporate trust office of the Appropriate Trustee (except as otherwise specified pursuant to Section 2.03), or at the option of the Company, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt Security Register (or in the case of joint Holders, to such address of one of the joint Holders), unless such Holder otherwise directs, or, if provided pursuant to Section 2.03 and in accordance with arrangements satisfactory to the Trustees, at the option of the Holder by wire transfer to an account designated by the Holder.

(b) Subject to the foregoing provisions of this Section 2.12 and Section 2.17, each Debt Security of a particular series delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security of the same series shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debt Security.

Section 2.13 Securities Denominated in Other Currencies.

(a) Except as otherwise specified pursuant to Section 2.03 for Debt Securities of any series, payment of the principal of, and premium, if any, and interest on, Debt Securities of such series denominated in any Currency will be made in such Currency.

(b) In the event any Other Currency or currencies or units of two or more Currencies in which any payment with respect to any series of Debt Securities may be made ceases to be a freely convertible Currency on Canadian currency markets, for any date thereafter on which payment of principal of, or premium, if any, or interest on, the Debt Securities of a series is due, the Company shall select the Currency of payment for use on such date, all as shall be provided in the Debt Securities of such series. In such event, the Company shall, as shall be provided in the Debt Securities of such series, notify the Trustees of the Currency which it has selected to constitute the funds necessary to meet the Company’s obligations on such payment date and of the amount of such Currency to be paid. Such amount shall be determined as provided in the Debt Securities of such series. The payment to the Trustees with respect to such payment date shall be made by the Company solely in the Currency so selected in accordance with the terms of the Debt Securities of such series.

Section 2.14 Wire Transfers. Notwithstanding any other provision to the contrary in this Indenture, the Company may make any payment of monies required to be deposited with the Trustees on account of principal of, or premium, if any, or interest on, the Debt Securities (whether pursuant to Stated Maturity, optional or mandatory redemption payments, interest payments or otherwise) by wire transfer in immediately available funds to an account designated by the Trustees on or before the date such moneys are to be paid to the Holders of the Debt Securities in accordance with the terms hereof. If payment is made through the Trustee, by 11:00 a.m. (Calgary time) at least one Business Day prior to the related interest payment date for a Debt Security or to the date of mailing the checks for the interest due on such interest payment date, whichever is earlier, the Company shall deliver sufficient funds to the Appropriate Trustee by electronic transfer or certified check or make such other arrangements for the provision of funds as may be agreeable between the Appropriate Trustee and the Company in order to effect such interest payment hereunder.

Section 2.15 Securities Issuable in the Form of a Global Security.

(a) If the Company shall establish pursuant to Sections 2.01 and 2.03 that the Debt Securities of a particular series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Appropriate Trustee or its agent shall, in accordance with Section 2.05, authenticate and deliver, such Global Security or Securities, which (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented by such Global Security or Securities, or such portion thereof as the Company shall specify in an Officers’ Certificate, (ii) shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, (iii) shall be delivered by the Appropriate Trustee or its respective agent to the Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: ‘UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE [NAME OF DEPOSITARY], TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF [NAME OF DEPOSITARY] OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [NAME OF DEPOSITARY] (AND ANY PAYMENT IS MADE TO [NAME OF DEPOSITARY], OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [NAME OF DEPOSITARY]) ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, [NAME OF DEPOSITARY], HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF [NAME OF DEPOSITARY] OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF’, or such other legend as may then be required by the Depositary for such Global Security or Securities.

(b) Notwithstanding any other provision of this Section 2.15 or of Section 2.07 to the contrary, and subject to the provisions of paragraph (c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for definitive Debt Securities in registered form, a Global Security may be transferred, in whole but not in part and in the manner provided in Section 2.07, only by the Depositary to a nominee of the Depositary for such Global Security, or by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or a nominee of the Depositary to a successor Depositary for such Global Security selected or approved by the Company, or to a nominee of such successor Depositary.

(c) (i) If at any time the Depositary for a Global Security or Securities notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or Securities or if at any time the Depositary for the Debt Securities for such series shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or regulation, the Company shall appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company shall execute, and the Appropriate Trustee or its respective agent, upon receipt of a Company Order for the authentication and delivery of such individual Debt Securities of such series in exchange for such Global Security, will authenticate and deliver, individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such Global Security or Securities.

(ii) The Company may at any time and in its sole discretion determine that the Debt Securities of any series or portion thereof issued or issuable 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 individual Debt Securities of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such series or portion thereof in exchange for such Global Security or Securities.

(iii) If specified by the Company pursuant to Sections 2.01 and 2.03 with respect to Debt Securities issued or issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual Debt Securities of such series of like tenor and terms in definitive form on such terms as are acceptable to the Company, the Appropriate Trustee and such Depositary. Thereupon the Company shall execute, and the Appropriate Trustee or its respective agents upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series shall authenticate and deliver, without service charge, (A) to each Person specified by such Depositary a new Debt Security or Securities of the same series of like tenor and terms and 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 (B) to such Depositary a new Global Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt Securities delivered to Holders thereof.

(iv) In any exchange provided for in any of the preceding three paragraphs, the Company will execute and the Appropriate Trustee or its respective agent will authenticate and deliver individual Debt Securities. Upon the exchange of the entire principal amount of a Global Security for individual Debt Securities, such Global Security shall be canceled by the Appropriate Trustee or its respective agents. Except as provided in the preceding paragraph, Debt Securities issued in exchange for a Global Security pursuant to this Section 2.15 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 or the Registrar. The Appropriate Trustee or the Registrar shall deliver such Debt Securities to the Persons in whose names such Debt Securities are so registered.

(v) Payments in respect of the principal of and interest on any Debt Securities registered in the name of the Depositary or its nominee will be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Company and the Trustees may treat the Person in whose name the Debt Securities, including the Global Security, are registered as the owner thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Company, the Trustees, any Registrar, the paying agent or any agent of the Company or the Trustees will have any responsibility or liability for (A) any aspect of the records relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its nominee or any of the Depositary’s direct or indirect participants, or for maintaining, supervising or reviewing any records of the Depositary, its nominee or any of its direct or indirect participants relating to the beneficial ownership interests of the Global Security, (B) the payments to the beneficial owners of the Global Security of amounts paid to the Depositary or its nominee, or (C) any other matter relating to the actions and practices of the Depositary, its nominee or any of its direct or indirect participants. None of the Company, the Trustees or any such agent will be liable for any delay by the Depositary, its nominee, or any of its direct or indirect participants in identifying the beneficial owners of the Debt Securities, and the Company and the Trustees may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Debt Securities to be issued).

Section 2.16 Debt Securities to be Issued Periodically. Notwithstanding any contrary provision herein, if all Debt Securities of a series are not to be originally issued at one time, it shall not be necessary for the Company to deliver to the Trustees an Officers’ Certificate, resolutions of the Board of Directors, supplemental Indenture, Opinion of Counsel or written order or any other document otherwise required pursuant to Section 2.01, 2.03, 2.05 or 13.05 at or prior to the time of authentication of each Debt Security of such series if such documents are delivered to the Trustees or its respective agent at or prior to the authentication upon original issuance of the first such Debt Security of such series to be issued; provided, that any subsequent request by the Company to the Trustees to authenticate Debt Securities of only such series upon original issuance shall include a representation and warranty by the Company that, as of the date of such request, the statements made in the Officers’ Certificate for only such series delivered pursuant to Section 2.05 or 13.05 are true and correct as if made on such date and that the Opinion of Counsel delivered at or prior to such time of authentication of an original issuance of Debt Securities shall specifically state that it shall relate to all subsequent issuances of Debt Securities of only such series that are identical to the Debt Securities issued in the first issuance of Debt Securities of only such series.

A Company Order, delivered by the Company to the Trustees in the circumstances set forth in the preceding paragraph, may provide that Debt Securities which are the subject thereof will be authenticated and delivered by the Trustees or their respective agents on original issue from time to time upon the written order of Persons designated in such written order and that such Persons are authorized to determine, consistent with the Officers’ Certificate, supplemental Indenture or resolution of the Board of Directors relating to such written order, such terms and conditions of such Debt Securities as are specified in such Officers’ Certificate, supplemental Indenture or such resolution.

Section 2.17 Defaulted Interest.

(a) Any interest on any Debt Security of a particular series which is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in the Debt Securities of such series and in this Indenture (herein called “Defaulted Interest”) shall, if such Debt Security is a Debt Security, forthwith cease to be payable to the Holder thereof on the relevant record date by virtue of having been such Holder, and such Defaulted Interest (plus interest on such Defaulted Interest to the extent lawful) may be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Debt Securities of such series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall promptly notify the Trustees in writing of the amount of Defaulted Interest proposed to be paid on each such Debt Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustees 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 Trustees 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 as in this clause provided. Thereupon the Trustees shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustees of the notice of the proposed payment. The Trustees shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage pre-paid, to each Holder thereof at its address as it appears in the Debt Security Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Debt Securities of such series are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii).

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

Section 2.18 Judgments. The obligation, if any, of the Company to pay the principal of, and premium, if any, and interest on, the Debt Securities of any series in Other Currency or Dollars (the “Designated Currency”) as may be specified pursuant to Section 2.03 is of the essence and the Company agrees that, (a) to the fullest extent possible under applicable law, judgments in respect of Debt Securities of such series shall be given in the Designated Currency; (b) the obligation of the Company to make payments in the Designated Currency of the principal of, and premium, if any, and interest on, such Debt Securities shall, notwithstanding any payment in any other Currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the Designated Currency that the Holder receiving such payment may, in accordance with normal banking procedures, purchase with the sum paid in such other Currency (after any premium and cost of exchange) on the Business Day in the country of issue of the Designated Currency or in the international banking community (in the case of a composite currency) immediately following the day on which such Holder receives such payment; (c) if the amount in the Designated Currency that may be so purchased for any reason falls short of the amount originally due, the Company shall pay such additional amounts as may be necessary to compensate for such shortfall; and (d) any obligation of the Company not discharged by such payment shall be due as a separate and independent obligation and, until discharged as provided herein, shall continue in full force and effect.

Section 2.19 CUSIP Numbers. The Company, in issuing the Debt Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustees shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, that any such notice may state that no representation is made as to the accuracy 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 Company will promptly notify the Trustees of any change in the “CUSIP” numbers.

ARTICLE III

REDEMPTION OF DEBT SECURITIES

Section 3.01 Applicability of Article. The provisions of this Article shall be applicable to the Debt Securities of any series which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 2.03 for Debt Securities of such series.

Section 3.02 Notices to Trustee. If the Company elects to redeem Debt Securities in accordance with their terms, it must furnish to the Trustees, at least three Business Days before notice of redemption is required to be mailed or sent to Holders pursuant to Section 3.04 hereof (unless a shorter time shall be agreed to by the Trustees) an Officers’ Certificate setting forth:

(a) the clause of this Indenture pursuant to which the redemption shall occur;

(b) the redemption date;

(d) the principal amount of Debt Securities to be redeemed; and

(e) the redemption price or the method by which it is to be determined.

Section 3.03 Selection of Debt Securities to be Redeemed. If less than all of the Debt Securities of like tenor and terms of a series are to be redeemed (other than pursuant to mandatory sinking fund redemptions) at any time, unless otherwise permitted by the terms of a resolution of the Board of Directors and set forth in an Officers’ Certificate, or any supplement to the Indenture in respect of such Debt Securities or required by law or applicable stock exchange or Depositary requirements, the Trustees will select, on a pro rata basis (or, in the case of Global Securities, based on the method as the Depositary or its nominee or successor may require or, where such nominee or successor is a Trustee, a method that most nearly approximates pro rata selection unless otherwise required by law), by lot or by such other method as in its sole discretion it shall deem appropriate and fair, the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed. The Trustees shall promptly notify the Company in writing of the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed.

In the event of partial redemption, the particular Debt Securities to be redeemed will be selected, unless otherwise provided herein, not less than 15 nor more than 60 days prior to the redemption date by the Trustees from the outstanding Debt Securities not previously called for redemption.

Provisions of this Indenture that apply to Debt Securities called for redemption also apply to portions of Debt Securities called for redemption.

Section 3.04 Notice of Redemption. At least 10 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail (or, in the case of Global Securities, pursuant to the applicable procedures of the Depositary), a notice of redemption to each Holder whose Debt Securities are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Debt Securities or a satisfaction and discharge of this Indenture pursuant to Article XII hereof.

The notice will identify the Debt Securities (including CUSIP numbers) to be redeemed and will state:

(a) the redemption date;

(b) the redemption price (or the method by which it will be determined);

(c) if any Debt Securities are being redeemed in part, the portion of the principal amount of such Debt Securities to be redeemed and that, after the redemption date upon surrender of such Debt Securities, a new Debt Security or Securities in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Debt Security;

(d) the name and address of the paying agent;

(e) that Debt Securities called for redemption must be surrendered to the paying agent to collect the redemption price;

(f) that, unless the Company defaults in making such redemption payment, or a condition precedent with respect to such redemption has not been satisfied or waived, interest on the Debt Securities called for redemption ceases to accrue on and after the redemption date;

(g) the paragraph of the Debt Securities and/or Section of this Indenture or any supplemental Indenture pursuant to which the Debt Securities called for redemption are being redeemed;

(h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Debt Securities; and

(i) if such redemption is subject to satisfaction of one or more conditions precedent, (i) a description of such condition or conditions precedent and (ii) that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived (provided, that in no event shall such date of redemption be delayed to a date later than 60 days after the date on which such notice was sent), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date as so delayed.

At the Company’s request, the Trustees will give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company has delivered to the Trustees an Officers’ Certificate in accordance with Section 3.02.

Section 3.05 Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.04 hereof, the Debt Securities called for redemption become due and payable on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived. The Company shall provide written notice of the satisfaction or waiver of such conditions, the delay of such date of redemption or the rescission of such notice of redemption to the Trustees prior to the close of business one Business Day prior to the date of redemption, and the Trustees shall provide such notice to each Holder in the same manner in which the notice of redemption was given. Upon receipt of such notice of the delay of such date of redemption or the rescission of such notice of redemption, such date of redemption shall be automatically delayed or such notice of redemption shall be automatically rescinded, as applicable, and the redemption of the Debt Securities shall be automatically delayed or rescinded and cancelled, as applicable, as provided in such notice.

Section 3.06 Payment of Debt Securities Called for Redemption. If notice of redemption has been given as provided in Section 3.04, the Debt Securities or portions of Debt Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the Place or Places of Payment stated in such notice at the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Debt Securities at the applicable redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt Securities of any series so called for redemption shall cease to accrue, and any original issue discount in the case of Original Issue Discount Debt Securities shall cease to accrue. On presentation and surrender of such Debt Securities at the Place or Places of Payment in said notice specified, the said Debt Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption.

Any Debt Security that is to be redeemed only in part shall be surrendered at the corporate trust office or such other office or agency of the Company as is specified pursuant to Section 2.03 with, if the Company, the Registrar or the Trustees so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustees duly executed by, the Holder thereof or its attorney duly authorized in writing, and the Company shall execute, and the Trustees shall authenticate and deliver to the Holder of such Debt Security without service charge, a new Debt Security or Debt Securities of the same series, of like tenor and form, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Debt Security so surrendered; except that if a Global Security is so surrendered, the Company shall execute, and the Trustees shall authenticate and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Debt Security providing appropriate space for such notation, at the option of the Holder thereof, the Trustees, in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion thereof.

Section 3.07 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as an “optional sinking fund payment.”

If provided for by the terms of Debt Securities of any series, in lieu of making all or any part of any mandatory sinking fund payment with respect to any Debt Securities of a series in cash, the Company may at its option (a) deliver to the Trustees the Debt Securities of that series theretofore purchased or otherwise acquired by the Company or (b) receive credit for the principal amount of Debt Securities of that series which have been redeemed either at the election of the Company pursuant to the terms of such Debt Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Debt Securities, resolution or supplemental Indenture; provided, that such Debt Securities have not been previously so credited. If provided for by the terms of Debt Securities of any series, such Debt Securities shall be received and credited for such purpose by the Trustees at the redemption price specified in such Debt Securities, resolution or supplemental Indenture for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

Section 3.08 Redemption of Debt Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Debt Securities, the Company will deliver to the Trustees an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, any resolution or supplemental Indenture, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) and the portion thereof, if any, which is to be satisfied by delivering and crediting Debt Securities of that series pursuant to Section 3.07 (which Debt Securities, if not previously redeemed, will accompany such certificate) and whether the Company intends to exercise its right to make any permitted optional sinking fund payment with respect to such series. Such certificate shall also state that no Event of Default has occurred and is continuing with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Company to deliver such certificate (or to deliver the Debt Securities specified in this paragraph) shall not constitute a Default, but such failure shall require that the sinking fund payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Debt Securities subject to a mandatory sinking fund payment without the option to deliver or credit Debt Securities as provided in this Section 3.08 and without the right to make any optional sinking fund payment, if any, with respect to such series.

Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made in cash which shall equal or exceed $100,000 (or a lesser sum if the Company shall so request) with respect to the Debt Securities of any particular series shall be applied by the Trustees on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Debt Securities at the redemption price specified in such Debt Securities, resolution or supplemental Indenture for operation of the sinking fund together with any accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustees to the redemption of Debt Securities shall be added to the next cash sinking fund payment received by the Trustees for such series and, together with such payment, shall be applied in accordance with the provisions of this Section 3.08. Any and all sinking fund moneys with respect to the Debt Securities of any particular series held by the Trustees on the last sinking fund payment date with respect to Debt Securities of such series and not held for the payment or redemption of particular Debt Securities shall be applied by the Trustees, together with other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities of that series at its Stated Maturity.

The Trustees or Depositary shall select the Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.03 and the Company shall cause notice of the redemption thereof to be given in the manner provided in Section 3.04 except that the notice of redemption shall also state that the Debt Securities are being redeemed by operation of the sinking fund. Such notice having been duly given, the redemption of such Debt Securities shall be made upon the terms and in the manner stated in this Section 3.08.

At least one Business Day before each sinking fund payment date, the Company shall pay to the Trustees (or, if the Company is acting as its own paying agent, the Company shall segregate and hold in trust) in cash a sum in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) equal to any interest accrued to the date fixed for redemption of Debt Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 3.08.

The Trustees shall not redeem any Debt Securities of a series with sinking fund moneys or mail any notice of redemption of such Debt Securities by operation of the sinking fund for such series during the continuance of a Default in payment of interest on such Debt Securities or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to such Debt Securities, except that if the notice of redemption of any such Debt Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustees shall redeem such Debt Securities if cash sufficient for that purpose shall be deposited with the Trustees for that purpose in accordance with the terms of this Article III. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such Default or Event of Default shall occur and any moneys thereafter paid into such sinking fund shall, during the continuance of such Default or Event of Default, be held as security for the payment of such Debt Securities; provided, however, that in case such Event of Default or Default shall have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date for such Debt Securities on which such moneys may be applied pursuant to the provisions of this Section 3.08.

ARTICLE IV

Each installment of interest on the Debt Securities may at the Company’s option be paid by wire transfer or by mailing checks for such interest payable to the Person entitled thereto pursuant to Section 2.07(a) to the address of such Person as it appears on the Debt Security Register.

Except as otherwise provided in this Indenture, the supplemental Indenture or a resolution of the Board of Directors and set forth in an Officers’ Certificate, principal of and premium and interest on Debt Securities of any series shall be considered paid on the date due if on such date as of 11:00 a.m. (New York City time) the Appropriate Trustee or any paying agent holds in accordance with this Indenture money sufficient to pay in the Currency in which the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) all principal, premium and interest then due and, in the case of Debt Securities subordinated pursuant to the terms of such Debt Securities, resolution of the Board of Directors or supplemental Indenture, the Appropriate Trustee or such paying agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture.

The Company will maintain in each Place of Payment for any series of Debt Securities an office or agency where Debt Securities of such series may be presented or surrendered for payment, where Debt Securities of such series may be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Debt Securities of such series and this Indenture may be served. The Company will give prompt written notice to the Trustees of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustees with the address thereof, such presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustees, and the Company hereby appoints the Trustees as its agent to receive all presentations, surrenders, notices and demands.

The Company may also from time to time designate different or additional offices or agencies to be maintained for such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations described in the preceding paragraph. The Company will give prompt written notice to the Trustees of any such additional designation or rescission of designation and any change in the location of any such different or additional office or agency.

Section 4.03 Appointment to Fill a Vacancy in the Office of Trustee. The Company, whenever necessary to avoid or fill a vacancy in the office of a Trustee, will appoint, in the manner provided in Section 7.08, a Trustee, so that, except as otherwise set forth herein, there shall at all times be a Canadian Trustee and a U.S. Trustee hereunder with respect to each series of Debt Securities.

Section 4.04 Duties of Paying Agents, etc.

(a) The Company shall cause each paying agent, if any, other than the Trustees, to execute and deliver to the Trustees an instrument in which such agent shall agree with the Trustees, subject to the provisions of this Section 4.04,

(iii) that it will at any time during the continuance of an Event of Default, upon the written request of the Trustees, forthwith pay to the Trustees all sums so held by it as such agent.

If an Event of Default described in clause (f) or (g) occurs, then and in each and every such case, unless the principal of, premium (if any) and interest on all the Debt Securities shall have become due and payable, the principal of, premium (if any) (or, if any Debt Securities are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms thereto) and interest on all the Debt Securities then Outstanding hereunder shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustees or any Holders, anything in this Indenture or in the Debt Securities contained to the contrary notwithstanding.

The Holders of a majority in aggregate principal amount of the Debt Securities of a particular series by notice to the Trustees may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree already rendered and if all existing Events of Default have been cured or waived except nonpayment of principal, premium (if any) or interest that has become due solely because of acceleration. Upon any such rescission, the parties hereto shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the parties hereto shall continue as though no such proceeding had been taken.

No such act or omission either of the Trustees or of the Holders shall extend to or be taken in any manner whatsoever to affect any subsequent Event of Default or the rights resulting therefrom.

In case the Trustees or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustees or such Holder, then and in every such case the parties hereto shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the parties hereto shall continue as though no such proceeding had been taken.

The foregoing Events of Default shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

Section 6.02 Collection of Indebtedness by Trustees, etc. If an Event of Default occurs and is continuing, each Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid or enforce the performance of any provision of the Debt Securities of the affected series or this Indenture, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Company upon the Debt Securities appertaining thereto, of such series (and collect in the manner provided by law out of the property of the Company upon the Debt Securities of such series wherever situated the moneys adjudged or decreed to be payable).

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company upon the Debt Securities of any series under the Bankruptcy and Insolvency Act (Canada), the Companies’ Creditors Arrangement Act (Canada), the U.S. Federal Bankruptcy Code, ABCA or any other federal, provincial, state or foreign bankruptcy, insolvency or analogous laws, or the issuance of a sequestration order or the appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Company or in receipt of any substantial part of the property of the Company, or in case of any other similar judicial proceedings relative to the Company upon the Debt Securities of any series, its creditors or its property, the Trustees, irrespective of whether the principal of Debt Securities of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustees shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Debt Securities of such series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustees (including any claim for reasonable compensation to the Trustees, its respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities Incurred, and all advances made, by the Trustees except as a result of its negligence or bad faith) and of the Holders thereof allowed in any such judicial proceedings relative to the Company, its creditors or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of such Holders and of the Trustees on their behalf, and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of such Holders to make payments to the Trustees, and, in the event that the Trustees shall consent to the making of payments directly to such Holders, to pay to the Trustees such amount as shall be sufficient to cover reasonable compensation to the Trustees, their agents, attorneys and counsel, and all other reasonable expenses and liabilities Incurred, and all advances made, by the Trustees except as a result of its negligence or bad faith.

SECOND: In case the principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall not have become due, to the payment of interest on the Debt Securities of such series in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustees) upon the overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities of such series, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference;

THIRD: In case the principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Debt Securities of such series for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustees) upon overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities of such series; and, in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Debt Securities of such series, then to the payment of such principal and premium, if any, and interest, without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Debt Security of such series over any Debt Security of such series, ratably to the aggregate of such principal and premium, if any, and interest; and

Section 6.04 Limitation on Suits by Holders. No Holder of any Debt Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any action, suit or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to this Indenture, or for the appointment of a liquidator, receiver or trustee, or for a receiving order under the Bankruptcy and Insolvency Act (Canada), or to have the Company wound up or to file or prove a claim in any liquidation or bankruptcy proceeding or for any other remedy hereunder, unless such Holder previously shall have given to the Trustees written notice of an Event of Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 25% in aggregate principal amount of the Outstanding Debt Securities of that series shall have made written request upon the Trustees to institute such action or proceedings in respect of such Event of Default in its own name as Trustees hereunder and shall have offered to the Trustees such indemnity as it may require against the costs, expenses and liabilities to be Incurred therein or thereby, and the Trustees, for 90 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustees pursuant to Section 6.06; it being understood and intended, and being expressly covenanted by the Holder of every Debt Security and the Trustees, that no one or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any Holders, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all such Holders. For the protection and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustees shall be entitled to such relief as can be given either at law or in equity.

Section 6.05 Remedies Cumulative; Delay or Omission in Exercise of Rights Not a Waiver of Default. All powers and remedies given by this Article VI to the Trustees or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustees or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustees or of any Holder to exercise any right or power accruing upon any Default occurring and continuing as aforesaid, shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence therein; and, subject to the provisions of Section 6.04, every power and remedy given by this Article VI or by law to the Trustees or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustees or by the Holders.

Section 6.06 Rights of Holders of Majority in Principal Amount of Debt Securities to Direct Trustees and to Waive Default. The Holders of a majority in aggregate principal amount of the Debt Securities of any series at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustees, or exercising any trust or power conferred on the Trustees, with respect to the Debt Securities of such series; provided, however, that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture, and that subject to the provisions of Section 7.01, the Trustees shall have the right to decline to follow any such direction if the Trustees being advised by counsel shall determine that the action so directed may not lawfully be taken, or if the Trustees shall by a responsible officer or officers determine that the action so directed would involve it in personal liability or would be unjustly prejudicial to Holders of Debt Securities of such series not taking part in such direction; and provided, further, however, that nothing in this Indenture contained shall impair the right of the Trustees to take any action deemed proper by the Trustees and which is not inconsistent with such direction by such Holders. Prior to the acceleration of the maturity of the Debt Securities of any series, as provided in Section 6.01, the Holders of a majority in aggregate principal amount of the Debt Securities of that series at the time Outstanding may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series specified in Section 6.01 as modified by the resolutions of the Board of Directors and set forth in an Officers’ Certificate or the supplemental Indenture applicable to Debt Securities of that series, except (a) a Default in the payment of the principal of, and premium, if any, or interest on, any of the Debt Securities and (b) a Default in respect of a provision that under Section 10.02 cannot be amended without the consent of each Holder affected thereby. In case of any such waiver, such Default shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, and the Company, the Trustees and the Holders of the Debt Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.07 Trustees to Give Notice of Defaults Known to It, but May Withhold Such Notice in Certain Circumstances. If a Default or Event of Default occurs and is continuing and is known to a Trustee, such Trustee must send to each Holder of the Debt Securities a notice of the Default or Event of Default within 30 days after it occurs and in accordance with Section 313(c) of the Trust Indenture Act, unless such Defaults shall have been cured or waived before the giving of such notice; provided, that, except in the case of Default in the payment of the principal of, or premium, if any, or interest on, any of the Debt Securities of such series or in the making of any sinking fund payment with respect to the Debt Securities of such series, a Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a committee of directors or responsible officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders thereof. The Trustee shall advise the Company in writing of such determination to withhold notice. The Trustee, however, may withhold from Holders of the Debt Securities a notice of any continuing Default or Event of Default if it determines that withholding such notice is in their interest, except a Default or Event of Default relating to the payment of principal of, premium, if any, on, or interest, if any, on, the Debt Securities.

A Trustee will not be deemed to have notice of any Default or Event of Default, except Events of Default under Section 6.01(a) or 6.01(b) hereof, unless a responsible officer of a Trustee has actual knowledge thereof or unless written notice of any event that 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 6.08 Requirement of an Undertaking To Pay Costs in Certain Suits under the Indenture or Against the Trustees. All parties to this Indenture agree, and each Holder of any Debt Security by its acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustees for any action taken or omitted by them as Trustees, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit in the manner and to the extent provided in the Trust Indenture Act, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.08 shall not apply to any suit instituted by the Trustees, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than ten percent in principal amount of the Outstanding Debt Securities of that series or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any Debt Security on or after the due date for such payment expressed in such Debt Security.

ARTICLE VII

CONCERNING THE TRUSTEE

Section 7.01 Certain Duties and Responsibilities. The Trustees, prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred, undertake to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustees shall exercise such of the rights and powers vested in them by this Indenture, and use the same degree of care and skill in their exercise, as, for the U.S. Trustee, a prudent man, and for the Canadian Trustee, a reasonably prudent trustee, would exercise or use under the circumstances in the conduct of his own affairs.

No provision of this Indenture shall be construed to relieve a Trustee from liability for its own negligent action, its own negligent failure to act, its own bad faith, or its own willful misconduct, except that:

(a) this subsection shall not be construed to limit the effect of the first paragraph of this Section 7.01;

(b) prior to the occurrence of an Event of Default with respect to the Debt Securities of a series and after the curing or waiving of all Events of Default with respect to such series which may have occurred:

(i) the duties and obligations of the Trustees with respect to Debt Securities of any series shall be determined solely by the express provisions of this Indenture, and the Trustees shall not be liable except for the performance of such duties and obligations with respect to such series as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to such series shall be read into this Indenture against the Trustees; and

(k) Anything in this Indenture to the contrary notwithstanding, in no event shall the Trustees be liable for special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustees have been advised of the likelihood of such loss or damage and regardless of the form of action.

Section 7.03 Trustee Not Liable for Recitals in Indenture or in Debt Securities. The recitals contained herein, in the Debt Securities (except the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustees assume no responsibility for the correctness of the same. The Trustees make no representations as to the validity or sufficiency of this Indenture or of the Debt Securities of any series, except that each Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Debt Securities, as applicable, and perform its obligations hereunder, and that, for the U.S. Trustee, the statements made by it or to be made by it in a Statement of Eligibility and Qualification on Form T-1 or Form T-3 supplied to the Company are true and accurate. The Trustees shall not be accountable for the use or application by the Company of any of the Debt Securities or of the proceeds thereof. A U.S. Trustee that has resigned or was removed shall remain subject to Section 311(a) of the Trust Indenture Act to the extent provided therein.

Section 7.04 Trustees, Paying Agent or Registrar May Own Debt Securities. The Trustees or any paying agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Debt Securities and subject to the provisions of the Trust Indenture Act relating to conflicts of interest and preferential claims may otherwise deal with the Company with the same rights it would have if it were not Trustee, paying agent or Registrar.

Section 7.05 Moneys Received by Trustees to Be Held in Trust. Subject to the provisions of Section 12.05, all moneys received by the Trustees shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustees will not be liable for interest on any moneys received by them hereunder, except as the Trustees may agree in writing with the Company.

Section 7.06 Compensation and Reimbursement. The Company covenants and agrees to pay to the Trustees from time to time, and the Trustees shall be entitled to, reasonable compensation for all services rendered by it hereunder (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and, except as otherwise expressly provided herein, the Company will pay or reimburse the Trustees upon its request for all reasonable costs, charges, expenses, disbursements and advances Incurred or made by the Trustees in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents, attorneys and counsel and of all Persons not regularly in its employ and with the execution of the trusts hereby created). The Company also covenants to indemnify the Trustees and any predecessor Trustees for, and to hold it harmless against, any and all loss, liability, claim, damage or expense Incurred without negligence, willful misconduct or bad faith on the part of the Trustees, arising out of or in connection with the acceptance or administration of this trust or trusts hereunder, including the reasonable costs and expenses of defending itself against any claim of liability (whether brought by the Company, any Holder or otherwise) in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the Company under this Section 7.06 to compensate and indemnify the Trustees and to pay or reimburse the Trustees for costs, expenses, disbursements and advances (including the costs and expenses of enforcing the terms of this Indenture including the indemnification provided in this Section 7.06 and of defending itself against any claims) which shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the resignation or removal of either Trustee. The Company and the Holders agree that such additional indebtedness shall be secured by a Lien prior to that of the Debt Securities upon all property and funds held or collected by the Trustees, as such, except funds held in trust for the payment of principal of, and premium, if any, or interest on, particular Debt Securities.

When the Trustees incurs expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency, reorganization or other similar law.

Section 7.07 Right of Trustees to Rely on an Officers’ Certificate Where No Other Evidence Specifically Prescribed. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustees shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustees, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustees and such certificate, in the absence of negligence or bad faith on the part of the Trustees, shall be full warrant to the Trustees for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 7.08 Separate Trustees; Replacement of Trustees. The Company may, but need not, further appoint a separate Trustee for any one or more series of Debt Securities. Any Trustee may resign with respect to one or more or all series of Debt Securities at any time by giving thirty (30) days written notice to the Company. The Holders of a majority in principal amount of the Debt Securities of a particular series may remove the Trustees for such series and only such series by so notifying such Trustees with thirty (30) days written notice and may appoint a successor Trustee. The Company shall remove a Trustee if:

(a) the Trustee fails to comply with Section 7.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting.

If a Canadian Trustee under this Indenture is no longer required by Trust Indenture Legislation, then the Company by a resolution of the Board may remove the Canadian Trustee and shall not be required to replace it, notwithstanding any other provision of this Indenture.

If either Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Debt Securities of a particular series and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of either Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of this Section 7.08. However, the Company shall not be required to appoint a successor Trustee to the Canadian Trustee if the Canadian Trustee resigns or is removed and a Canadian Trustee under this Indenture is no longer required under Trust Indenture Legislation.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of Debt Securities of each applicable series. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.06.

If a successor Trustee does not take office within 60 days after the retiring Trustee gives notice of resignation or is removed, the retiring Trustee or the Holders of 25% in principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment of a successor Trustee for the Debt Securities of such series.

If a Trustee fails to comply with Section 7.10, any Holder of Debt Securities of any applicable series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series.

Notwithstanding the replacement of the Trustees pursuant to this Section 7.08, the Company’s obligations under Section 7.06 shall continue for the benefit of a retiring Trustee.

In the case of the appointment hereunder of a separate or successor Trustee with respect to the Debt Securities of one or more series, the Company, any retiring Trustee and each successor or separate Trustee with respect to the Debt Securities of any applicable series shall execute and deliver an Indenture supplemental hereto (i) which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of any retiring Trustee with respect to the Debt Securities of any series as to which any such retiring Trustee is not retiring shall continue to be vested in such retiring Trustee and (ii) that 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 separate, retiring or successor 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.

Section 7.09 Successor Trustees by Merger. If a Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to a Trustee shall succeed to the trusts created by this Indenture any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Debt Securities so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Debt Securities or in this Indenture provided that the certificate of the Trustee shall have.

Section 7.10 Eligibility; Disqualification. For so long as required by the Trust Indenture Act, there shall be a U.S. Trustee under this Indenture. The U.S. Trustee shall at all times satisfy the requirements of Section 310(a) of the Trust Indenture Act. The U.S. Trustee shall have a combined capital and surplus of at least $10,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Debt Securities of a particular series or Person directly or indirectly controlling, controlled by or under common control with such obligor shall serve as U.S. Trustee for the Debt Securities of such series. The U.S. Trustee shall comply with Section 310(b) of the Trust Indenture Act; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act this Indenture or any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met.

For so long as required by Trust Indenture Legislation, there shall be a Canadian Trustee under this Indenture. The Canadian Trustee shall at all times be a resident or authorized to do business in the Province of Alberta and any other province in Canada where Holders may be resident from time to time. The Canadian Trustee represents and warrants that no material conflict of interest exists in the Canadian Trustee’s role as a fiduciary hereunder and agrees that in the event of a material conflict of interest arising hereafter it will, within 30 days after ascertaining that it has such material conflict of interest, either eliminate the same or resign its trust hereunder. If any such material conflict of interests exists or hereafter shall exist, the validity and enforceability of this Indenture shall not be affected in any manner whatsoever by reason thereof.

Section 7.11 Preferential Collection of Claims Against Company. The Trustees shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein.

Section 7.12 Compliance with Tax Laws. The Trustees hereby agree to comply with all Canadian and U.S. federal income tax information reporting and withholding requirements applicable to it with respect to payments of premium (if any) and interest on the Debt Securities, whether acting as Trustees, Registrar, paying agent or otherwise with respect to the Debt Securities.

Section 7.13 Trustee’s Application for Instructions From the Company. Any application by the Trustees for written instructions from the Company may, at the option of the Trustees, set forth in writing any action proposed to be taken or omitted by the Trustees under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustees shall not be liable to the Company for any action taken by, or omission of, the Trustees in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than ten Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustees shall have received written instructions in response to such application specifying the action to be taken or omitted.

Section 7.14 Privacy. The parties hereto acknowledge that Canadian federal and provincial legislation addressing the protection of individuals’ personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Indenture. Despite any other provision of this Indenture, neither party shall take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Company, prior to transferring, or causing to be transferred, personal information to any Canadian Trustee, shall obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have been previously given and can be relied on or are not required under Privacy Laws. The Canadian Trustee shall use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws. Specifically, the Canadian Trustee agrees to:

(i) have designated a chief privacy officer;

(ii) maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry;

(iii) use personal information solely for the purposes of providing its services under or ancillary to this Indenture and not to use it for any other purpose except with the consent and direction of the Company;

(iv) not sell or otherwise improperly disclose personal information to any third party; and

(v) use employee administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft or unauthorized access, use or modification.

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

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

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

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

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

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

Section 7.15 Joint Trustees. The rights, powers, duties and obligations conferred and imposed upon the Trustees are conferred and imposed upon and shall be exercised and performed by the Canadian Trustee and the U.S. Trustee individually, except to the extent the Trustees are required under Trust Indenture Legislation to perform such acts jointly, and neither Trustee shall be liable or responsible for the acts or omissions of the other Trustee. If the Canadian Trustee and the U.S. Trustee are unable to agree jointly to act or refrain from acting, the Appropriate Trustee shall make the decision in accordance with its applicable legislation. Unless the context implies or requires otherwise, any written notice, request, direction, certificate, instruction, opinion or other document (each such document, a “Writing”) delivered pursuant to any provision of this Indenture to any of the Canadian Trustee and the U.S. Trustee shall be deemed for all purposes of this Indenture as delivery of such Writing to the Trustee. Each such Trustee in receipt of such writing shall notify such other Trustee of its receipt of such Writing within two Business Days of such receipt; provided, however, that any failure of such Trustee in receipt of such Writing to so notify such other Trustee shall not be deemed as a deficiency in the delivery of such Writing to the Trustee.

Section 7.16 Anti-Money Laundering and Anti-Terrorism. In order to comply with applicable law, including those relating to the funding of terrorist activities and money laundering (for example, section 326 of the USA PATRIOT Act of the United States), the Trustees are required to obtain, verify, record and update certain information relating to individuals and entities which maintain a business relationship with the Trustees. Accordingly, the Company agrees to provide to the Trustees, upon its request from time to time such identifying information and documentation as may be available for the Company in order to enable the Trustees to comply with such applicable law. The Trustees shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Appropriate Trustee, in its sole judgment, acting reasonably, determines that such act might cause it to be in noncompliance with any applicable anti-money laundering or antiterrorist legislation, regulation or guideline. Further, should any Trustee, in its sole judgment, acting reasonably, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days’ prior written notice sent to the Company; provided, that (i) the Trustee’s written notice shall describe the circumstances of such non-compliance; and (ii) if such circumstances are rectified to the Trustee’s satisfaction within such 10-day period, then such resignation shall not be effective.

Section 7.17 Transfer of Funds to Trustees.

(a) Unless otherwise provided, payments to be made to the Holders of any Debt Securities with respect to the payment of principal, premium or interest (including as interest becomes due, upon redemptions or upon maturity), if any and as applicable, the Company, either directly or through one or more Trustees or any agents of the Trustees, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Trustee, such payment to the order of the Holder. Such payments may also be made through a paying agent. If payment is made through the Trustee or a paying agent, by 11:00 a.m. (Calgary time) at least one Business Day prior to the related payment date or to the date of mailing the checks for such payment, whichever is earlier, the Company shall deliver sufficient funds to the Trustee or paying agent, including to a designated account established for such payment, by electronic transfer or certified check or make such other arrangements for the provision of funds as may be agreeable between the Trustee or paying agent and the Company in order to effect such payment hereunder. The Company shall also deposit with the Trustee or paying agent a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee or paying agent in connection with such payments, including any charges or expenses incurred upon a redemption of Debt Securities. Every such deposit shall be irrevocable.

So long as the Debt Securities or any portion thereof are issued in the form of a Global Security, then all such payments on such Global Security shall be made by 11:00 a.m. (Calgary time) at least one Business Day prior to the related payment date by electronic funds transfer made payable to the Depositary or its nominee for subsequent payment to the beneficial Holders of the applicable interests in that Global Security, unless the Company and the Depositary otherwise agree.

(b) Neither the Trustees nor paying agent, as applicable, shall have any obligation to disburse funds in respect of any Debt Securities pursuant to Section 7.17(a) unless it has received written confirmation satisfactory to it that the funds have been deposited with it in sufficient amount to pay in full all amounts due and payable with respect to such payment for such Debt Securities. The Trustee or paying agent, as applicable, shall, if it accepts any funds received by it in the form of uncertified checks, be entitled to delay the time for release of such funds until such uncertified checks shall be determined to have cleared the financial institution upon which the same are drawn. Notwithstanding Section 7.17(a), with respect to the Canadian Trustee (i) all payments in excess of $25,000,000 (or such other amount as determined from time to time by the Canadian Payments Association or any successor thereto) shall be made by the use of the Large Value Transfer System (LVTS) and (ii) in the event that payment must be made to the Depositary, the Company shall remit payment to the Trustee or paying agent by LVTS.

ARTICLE VIII

CONCERNING THE HOLDERS

Section 8.01 Evidence of Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Debt Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article IX, (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders or (d) in the case of Debt Securities evidenced by Global Securities, by an electronic transmission or other message, whether or not in written format, that complies with the applicable procedures of the Depositary.

Section 8.02 Proof of Execution of Instruments and of Holding of Debt Securities. Subject to the provisions of Section 7.01, Section 7.02 and Section 9.02, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustees or in such manner as shall be satisfactory to the Trustees.

The ownership of Debt Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series.

The Trustees may require such additional proof of any matter referred to in this Section 8.02 as it shall deem necessary.

Section 8.03 Who May Be Deemed Owner of Debt Securities. Prior to due presentment for registration of transfer of any Debt Security, the Company, the Trustees, any paying agent and any Registrar may deem and treat the Person in whose name any Debt Security shall be registered upon the books of the Company as the absolute owner of such Debt Security (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and premium, if any, and (subject to Section 2.12 and 2.17) interest on such Debt Security and for all other purposes, and neither the Company nor the Trustees nor any paying agent nor any Registrar shall be affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, or upon its order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Debt Security.

None of the Company, the Trustees, any paying agent or the Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 8.04 Instruments Executed by Holders Bind Future Holders. At any time prior to (but not after) the evidencing to the Trustees, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such action, any Holder of a Debt Security which is shown by the evidence to be included in the Debt Securities the Holders of which have consented to such action may, by filing written notice with the Trustees at its corporate trust office and upon proof of holding as provided in Section 8.02 (or, in the case of Debt Securities evidenced by Global Securities, by complying with the applicable procedures of the Depositary), revoke such action so far as concerns such Debt Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Debt Security appertaining thereto, and of any Debt Security issued upon transfer thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities. Any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustees and the Holders of all the Debt Securities of such series.

Section 8.05 Record Dates for Actions by Holders. If the Company shall solicit from the Holders of Debt Securities of any series any action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action), the Company may, at its option, by resolution of the Board of Directors, fix in advance a record date for the determination of Holders of Debt Securities entitled to take such action, but the Company shall have no obligation to do so. Any such record date shall be fixed at the Company’s discretion. If such a record date is fixed, such action may be sought or given before or after the record date, but only the Holders of Debt Securities of record at the close of business on such record date shall be deemed to be Holders of Debt Securities 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 action, and for that purpose the Debt Securities of such series Outstanding shall be computed as of such record date. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder of a Debt Security and every subsequent Holder of the Debt Security or portion of the Debt Security that evidences the same debt as the consenting Holder’s Debt Security, even if notation of the consent is not made on any Debt Security. However, any such Holder or subsequent Holder may revoke the consent as to its Debt Security if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective.

The Trustees are hereby authorized to join with the Company in the execution of any such supplemental Indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustees shall not be obligated to enter into any such supplemental Indenture which affects their respective own rights, duties or immunities under this Indenture or otherwise.

Any supplemental Indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the Trustees without the consent of the Holders of any of the Debt Securities appertaining thereto at the time Outstanding, notwithstanding any of the provisions of Section 10.02.

After an amendment under this Section 10.01 becomes effective, the Company shall mail (including by electronic transmission) to Holders of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 10.01.

Section 10.02 Modification of Indenture with Consent of Holders of Debt Securities. Without notice to any Holder but with the consent (evidenced as provided in Section 8.01) of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such supplemental Indenture, the Company, when authorized by a resolution of the Board of Directors, and the Trustees may from time to time and at any time enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental Indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series; provided, that no such supplemental Indenture, without the consent of the Holders of each Debt Security so affected, shall (a) reduce the percentage in principal amount of Debt Securities of any series whose Holders must consent to an amendment; (b) reduce the rate of or extend the time for payment of interest on any Debt Security; (c) reduce the principal of or extend the Stated Maturity of any Debt Security; (d) reduce the premium payable upon the redemption of any Debt Security or change the time at which any Debt Security may or shall be redeemed in accordance with Article III; (e) make any Debt Security payable in Currency other than that stated in the Debt Security; (f) impair or affect the right of a Holder of Debt Securities to receive payment of principal of, and premium, if any, and interest on such Holder’s Debt Securities on or after the due dates therefor or impair or affect the right of a Holder of Debt Securities to institute suit for the enforcement of any such payment on or after such due dates; or (g) make any change in Section 6.06 or this Section 10.02.

A supplemental Indenture which changes or eliminates any covenant or other provision of this Indenture which has been expressly included solely for the benefit of one or more particular series of Debt Securities or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Debt Securities of any other series.

Upon the request of the Company, accompanied by a copy of a resolution of the Board of Directors authorizing the execution of any such supplemental Indenture, and upon the filing with the Trustees of evidence of the consent of Holders as aforesaid, the Trustees shall join with the Company in the execution of such supplemental Indenture unless such supplemental Indenture affects a Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case such Trustee may in its discretion but shall not be obligated to enter into such supplemental Indenture.

It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed supplemental Indenture, but it shall be sufficient if such consent shall approve the substance thereof.

After an amendment under this Section 10.02 becomes effective, the Company shall mail to Holders of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 10.02.

Section 10.03 Effect of Supplemental Indentures. Upon the execution of any supplemental Indenture pursuant to the provisions of this Article X, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustees, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental Indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

The Trustees, subject to the provisions of Sections 7.01 and 7.02, may receive and shall be fully protected in relying on an Officers’ Certificate and an Opinion of Counsel (at the sole expense of the Company) as conclusive evidence that any such supplemental Indenture complies with the provisions of this Article X, is authorized and permitted by the terms of this Indenture, and that all conditions precedent to such supplemental Indenture have been satisfied. Each Trustee may, but shall not be obligated to, enter into any such supplemental Indenture or amended and restated Indenture that adversely affects such Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise.

Section 10.04 Debt Securities May Bear Notation of Changes by Supplemental Indentures. Debt Securities of any series authenticated and delivered after the execution of any supplemental Indenture pursuant to the provisions of this Article X may, and shall if required by the Trustees, bear a notation in form approved by the Trustees as to any matter provided for in such supplemental Indenture. New Debt Securities of any series so modified as to conform, in the opinion of the Trustees and the Board of Directors, to any modification of this Indenture contained in any such supplemental Indenture may be prepared and executed by the Company, authenticated by the Appropriate Trustee and delivered in exchange for the Debt Securities of such series then Outstanding. Failure to make the appropriate notation or to issue a new Debt Security of such series shall not affect the validity of such amendment.

Section 10.05 Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Debt Securities appertaining thereto unless such consideration is offered to be paid to all Holders of the applicable series of Debt Securities that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

The Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all the Debt Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustees; and, upon the order of the Successor Company, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Appropriate Trustee shall authenticate and shall deliver any Debt Securities appertaining thereto, which previously shall have been signed and delivered by the officers of the Company to the Appropriate Trustee for authentication, and any Debt Securities appertaining thereto, which the Successor Company thereafter shall cause to be signed and delivered to the Appropriate Trustee for that purpose. All the Debt Securities appertaining thereto so issued shall in all respects have the same legal rank and benefit under this Indenture as the Debt Securities appertaining thereto theretofore or thereafter issued in accordance with the terms of this Indenture as though all such Debt Securities had been issued at the date of the execution hereof.

In case of any such consolidation, amalgamation, merger, sale or conveyance such changes in phraseology and form (but not in substance) may be made in the Debt Securities appertaining thereto thereafter to be issued as may be appropriate and as evidenced in a supplemental Indenture in accordance with Article XI.

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

Section 13.04 Governing Law; Conflict of Any Provision of the Indenture with the Trust Indenture Act.

(a) This Indenture and each Debt Security shall be governed by and construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein and shall be treated in all respects as Alberta contracts; provided, that the rights, protections, duties, obligations and immunities of the U.S. Trustee hereunder shall be governed by and construed under the laws of the State of New York.

(b) Each of the Company and the U.S. Trustee agrees to comply with all provisions of the Trust Indenture Act applicable to or binding upon it in connection with this Indenture and each Debt Security. If and to the extent that any provision of this Indenture, the Debt Security or applicable law limits, qualifies or conflicts with any mandatory requirement of the Trust Indenture Act (and notwithstanding any provisions of this Indenture or the Debt Security to the contrary), such mandatory requirement shall prevail. For greater certainty, if and to the extent that any provision of this Indenture, the Debt Security or applicable law limits, qualifies or conflicts with the duties imposed by Sections 310 to 318, inclusive, of the Trust Indenture Act, or conflicts with any provision required by or deemed to be included in this Indenture by operation of such Trust Indenture Act sections (and notwithstanding any provisions of this Indenture or the Debt Securities to the contrary), the Trust Indenture Act shall control.

Section 13.05 Officers’ Certificate and Opinion of Counsel to Be Furnished upon Application or Demand by the Company. Upon any application or demand by the Company to the Trustees to take, or refrain from taking, any action under any of the provisions of this Indenture, the Company shall furnish to the Trustees an Officers’ Certificate stating that all conditions precedent provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that, in the opinion of such counsel, all such conditions precedent have been complied with, except that in the case of any such application or demand as to which the furnishing of such document is specifically required by any provision of this Indenture relating to such particular application or demand, no additional certificate or opinion need be furnished.

Each certificate or opinion provided for in this Indenture and delivered to the Trustees with respect to compliance with a condition or covenant provided for in this Indenture shall include (a) a statement that the Person making such certificate or opinion has read such covenant or condition, (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based, (c) a statement that, in the opinion of such Person, that Person has made such examination or investigation as is necessary to enable that Person to express an informed opinion as to whether or not such covenant or condition has been complied with and (d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been complied with.

Section 13.06 Payments Due on Legal Holidays. In any case where the date of maturity of interest on or principal of and premium, if any, on the Debt Securities of a series or the date fixed for conversion, redemption or repayment of any Debt Security or the making of any sinking fund payment shall not be a Business Day at any Place of Payment for the Debt Securities of such series, then payment of interest or principal and premium, if any, or the making of such sinking fund payment, or in the case of a conversion, the issuance of securities, need not be made on such date at such Place of Payment, 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 date of maturity or the date fixed for redemption, and no interest shall accrue for the period after such date. If a record date is not a Business Day, the record date shall not be affected.

Section 13.07 Computation of Interest on Debt Securities. Interest, if any, on the Debt Securities shall be computed on the basis of a 360-day year of twelve 30-day months, except as may otherwise be provided pursuant to Section 2.03. For the purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which interest calculated under a Debt Security for any period in any calendar year (the “calculation period”) is equivalent, is the rate payable under a Debt Security in respect of the calculation period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator of which is the actual number of days in the calculation period. If the Canadian Trustee is appointed paying agent, it shall be entitled to rely on the calculations to be provided by the Company.

Section 13.08 Agent for Service; Submission to Jurisdiction; Waiver of Immunities.

(a) The Company hereby irrevocably and unconditionally submits to the jurisdiction of (i) a New York state or federal court located in The Borough of Manhattan, The City of New York and (ii) the courts of the Province of Alberta, in each case with all applicable courts of appeal therefrom, with respect to actions brought against it as a defendant, for purposes of all legal proceedings arising out of or relating to this Indenture or the Debt Securities or the transactions contemplated hereby or thereby; provided, that nothing herein shall be deemed to limit the ability of any party to this Indenture or the Debt Securities to bring suit in any other permissible jurisdiction. The Company hereby irrevocably submits to the non-exclusive jurisdiction of any such court in any such suit or proceeding, and it irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such proceeding brought in such a court, any claim that any such proceeding brought in such a court has been brought in an inconvenient forum and any objection based on place of residence or domicile.

(b) By the execution and delivery of this Indenture, the Company (i) acknowledges that it has irrevocably designated and appointed Cogency Global Inc., 122 East 42nd Street, 18th Floor, New York, NY 10168, as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Debt Securities or this Indenture that may be instituted a New York state or federal 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), and (ii) agrees that service of process upon Cogency Global Inc. and written notice of said service to the Company (mailed or delivered to the Company as specified herein), 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 Cogency Global Inc. in full force and effect so long as this Indenture shall be in full force and effect.

(c) 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 Debt Securities, to the extent permitted by law.

(d) 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 in any such court or any appellate court with respect thereto. The Company irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action, suit or proceeding in any such court.

(e) 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 will be the equivalent of such notice. Waivers of notice by Holders will be filed with the Appropriate Trustee, but such filing will not be a condition precedent to the validity of any action taken in reliance on such waiver.

(f) The Trustees agree to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile transmission or other similar unsecured electronic methods; provided, however, that (a) the party providing such written instructions, subsequent to such transmission of written instructions, shall provide the originally executed instructions or directions to the Appropriate Trustee in a timely manner, and such originally executed instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions. If the party elects to give a Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustees shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustees’ reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustees, including the risk of the Trustees acting on unauthorized instructions, and the risk or interception and misuse by third parties.

Section 13.09 No Recourse Against Others. An incorporator or any past, present or future director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Debt Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Debt Security, each Holder shall waive and release all such liability. The waiver and release shall be part of the consideration for the issue of the Debt Securities.

Section 13.10 Severability. In case any provision in this Indenture or the Debt Securities shall be invalid, illegal or unenforceable, such provision shall be deemed to be severed herefrom or therefrom and the validity, legality and enforceability of the remaining provisions shall not in any way be affected, prejudiced or impaired thereby.

Section 13.11 Effect of Headings. The article and section headings herein and in the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 13.12 Entire Agreement. This Indenture and all supplemental Indentures and Schedules hereto and thereto, and the Debt Securities issued hereunder and thereunder, together constitute the entire agreement between the parties hereto with respect to the indebtedness created hereunder and thereunder and under the Debt Securities and supersedes as of the date hereof all prior memoranda, agreements, negotiations, discussions and term sheets, whether oral or written, with respect to the indebtedness created hereunder or thereunder and under the Debt Securities.

Section 13.13 Indenture May Be Executed in Counterparts. This Indenture may be executed in several counterparts, each of which when so executed shall be deemed to be an original and such counterparts together shall constitute one and the same instrument. Delivery of an executed signature page to this Indenture by any party hereto by facsimile transmission, PDF or other form of electronic transmission, including through DocuSign and similar applications, shall be as effective as delivery of a manually executed copy of this Indenture by such party. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Indenture or any document to be signed in connection with this Indenture (including the Debt Securities and any Officer’s Certificate) shall be deemed to include electronic signatures, including digital signature provided by DocuSign (or such other digital signature provider as specified in writing to Trustees by the authorized representative), each of which shall be of the same legal effect, validity or enforceability as a manually executed signature. The Company agrees to assume all risks arising out of the use of digital signatures and electronic methods to submit communications to Trustees, including the risk of Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties.

Section 13.14 Formal Date. For the purpose of convenience, this Indenture may be referred to as bearing the formal date of January 25, 2021, irrespective of the actual date of execution hereof.

Section 13.15 Force Majeure. Except for the payment obligations of the Company contained herein or in any supplemental Indenture or resolution of the Board of Directors, neither party shall be liable to the other, or held in breach of this Indenture, if prevented, hindered, or delayed in the performance or observance of any provision contained herein by reason of act of God, riots, terrorism, acts of war, epidemics, pandemics, governmental action or judicial order, earthquakes, economic sanctions or any other similar causes (including, but not limited to, mechanical, electronic or communication interruptions, disruptions or failures). Performance times under this Indenture shall be extended for a period of time equivalent to the time lost because of any delay that is excusable under this Section 13.15.

Each Trustee hereby accepts the trusts in this Indenture upon the terms and conditions herein set forth.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly signed as of the date first written above.
