2.7 Certification

No Trust Notes shall be issued or, if issued, shall be obligatory or shall entitle the Holder thereof to the benefits of this Indenture until it has been certified by or on behalf of the Trustee substantially in the form set out in the applicable supplemental indenture hereto or in some other form approved by the Trustee, whose approval shall be conclusively evidenced by the certification thereof. Such certificate on any Trust Notes shall be conclusive evidence as against the Issuer that such Trust Notes are duly issued and is a valid obligation of the Issuer.

The certificate of the Trustee on any Trust Notes shall not be construed as a representation or warranty by the Trustee as to the validity of this Indenture or of the Trust Notes (except the due certification thereof) and the Trustee shall in no respect be liable or answerable for the use made of the Trust Notes or any of them or the proceeds thereof.

2.8 Concerning Interest

2.8.1 Unless otherwise provided in a supplemental indenture for a Series:

2.8.1.1 Every Trust Note, whether issued originally or in exchange for other Trust Notes, shall bear interest from and including its date of issue or from and including the last interest payment date to which interest shall have been paid or made available for payment on such Trust Notes, whichever shall be later.

2.8.1.2 Interest on each Trust Note shall cease to accrue from the earliest of: (i) the maturity date; or (ii) if such Trust Note is called for redemption, the date fixed for redemption, unless upon due presentation and surrender thereof for payment on or after the maturity date or the date fixed for redemption, as the case may be, such payment is improperly withheld or refused.

2.8.1.3 Wherever in this Indenture or the Trust Notes there is mention, in any context, of the payment of interest, such mention shall be deemed to include the payment of interest on amounts in default to the extent that, in such context, such interest is, was or would be payable pursuant to this Indenture or the Trust Notes, and express mention of interest on amounts in default in any of the provisions of this Indenture or the Trust Notes shall not be construed as excluding such interest in those provisions where such express mention is not made.

2.8.1.4 If an interest payment date falls on a day that is not a Business Day, the interest payment date will be postponed to the next Business Day, and no further interest or other sums will accrue in respect of such postponement.

2.9 Rank of Trust Notes

All Trust Notes created and issued under this Indenture shall be in all respects entitled, equally and rateably with all other Trust Notes created and issued under this Indenture, to the benefits hereof without preference, priority or distinction on account of the actual time or times of certification and delivery, all in accordance with the terms and provisions of this Indenture. The Trust Notes shall be direct, subordinated obligations of the Issuer, ranking equally and rateably with all other subordinated indebtedness of the Issuer from time to time issued and outstanding, except for indebtedness that, by its terms, ranks subordinate to the Trust Notes.

2.10 Registration of Trust Notes

2.10.1 Subject to section 2.11, the Issuer shall cause to be kept by and at the principal office of the Trustee in the City of Calgary, Alberta or such other location as it may designate from time to time, a central register of Holders, and at such other place or places or by such other registrar or registrars as the Issuer may designate or appoint, with the approval of the Trustee, branch registers, in which shall be entered the names and latest known addresses of the Holders of Trust Notes, and the other particulars, as prescribed by law, of the Trust Notes held by them respectively and of all transfers of Trust Notes. Such registration shall be noted on the Trust Notes by the Trustee or other registrar. Subject to section 2.11, no transfer of Trust Notes shall be effective as against the Issuer unless made on one of the appropriate registers by the Holder of the Trust Notes or the Holder’s executors or administrators or other legal representatives or the Holder’s attorney duly appointed by an instrument in form and execution satisfactory to the Trustee and upon compliance with such requirements as the Trustee or other registrar may prescribe, and unless such transfer shall have been duly noted on such Trust Notes by the Trustee or other registrar.

The Holder of Trust Notes may at any time and from time to time have the registration of such Trust Notes transferred from the register in which the registration thereof appears to another register maintained in another place authorized for that purpose under the provisions of this Indenture upon payment of a reasonable fee to be fixed by the Trustee.

2.10.4 None of the Issuer, the Trustee or any registrar shall be required:

2.10.4.1 to transfer or exchange any Trust Notes on any interest payment date or during the 10 Business Days immediately preceding any interest payment date; or

2.10.5 None of the Issuer, the Trustee or any registrar for any of the Trust Notes shall be charged with notice of or be bound to see to the execution of any trust, whether express, implied or constructive, in respect of any Trust Notes and may transfer any Trust Notes on the direction of a Holder thereof, whether named as trustee or otherwise, as though that Person were the beneficial owner thereof.

2.10.6 The Issuer shall have power at any time to close any branch register and in that event it shall transfer the records thereof to an existing register or to a new register and thereafter such Trust Notes shall be deemed to be registered on such existing or new register, as the case may be. In the event that the register in any place is closed and the records transferred to a register in another place, notice of such change shall be given to the Holders of the Trust Notes registered in the register so closed and the particulars of such change shall be recorded in the central register required to be kept in the City of Calgary, Alberta.

2.10.7 Every registrar shall, when requested to do so by the Issuer or the Trustee, furnish the Issuer or the Trustee, as the case may be, with a list of the names and addresses of the Holders of the Trust Notes showing the Series, principal amounts and serial numbers of such Trust Notes held by each Holder.

2.11.1 Notwithstanding any other provision of this Indenture, the Issuer may elect to have the Trust Notes of a Series issued hereunder represented in the form of one or more typewritten, English language, fully registered global certificates held by, or on behalf of, a Clearing Agency (or its nominee) as depository of the global certificate (for its Participants) and registered on the register maintained by the Trustee pursuant to section 2.10 in the name of the Clearing Agency (or its nominee). It is expressly acknowledged that any such registrations of ownership and transfers of such Trust Notes, or interests of Participants therein, will be made by the Clearing Agency only through the applicable Book-Entry System in accordance with policies and procedures of the Clearing Agency. Subject to this section 2.11, the rights of the holder of any beneficial interest in the Trust Notes of a Series represented by a global certificate (including the right to receive a certificate or other instrument evidencing an ownership interest in such Trust

Notes) shall be limited to those established by any agreement (including a book-entry securities services agreement or letter of representations of the Issuer to the Clearing Agency) between the Issuer and the Clearing Agency, by applicable law and agreements between the Clearing Agency and its Participants and between such Participants and the holder of such beneficial interest. Accordingly, except as provided herein, neither the Issuer nor the Trustee shall be under any obligation to deliver, nor shall the holder of such interest have any right to require the delivery of, a certificate evidencing Trust Notes of a Series to the holder of the interest in such Trust Notes. In the event of any conflict between this Indenture and any such agreement between the Issuer and a Clearing Agency, the terms of any such agreement shall prevail, subject to section 2.11.2.

2.11.2 Notwithstanding section 2.11.1, after the occurrence of an Event of Default or a breach of any of the covenants of the Issuer provided for in this Indenture which breach shall have continued unremedied for a period of 60 days after the Issuer has received notice of such breach, unless the Trustee (having regard to the subject matter of the breach) shall have agreed to a longer period and, in such event, within the period agreed to by the Trustee, the Holders of Trust Notes of a Series may at any time determine (which determination shall, for greater certainty, require an Ordinary Resolution and not an Extraordinary Resolution) that the continuation of the holding of the Trust Notes by only global certificates under the Book-Entry System is no longer in the best interests of such Holders.

2.11.3 Upon any determination made pursuant to section 2.11.2, or if required to do so by law, or if the applicable Book-Entry System ceases to exist, or if the Issuer determines that the applicable Clearing Agency is no longer willing or able to discharge properly its responsibilities as depository and the Issuer is unable to locate a qualified successor, or if the Issuer at its option elects or is required by applicable law or rules of any securities exchange to terminate the applicable Book-Entry System for any reason,

2.11.3.1 the Trustee shall notify the applicable Clearing Agency and shall request such Clearing Agency to notify the Participants of the availability of definitive fully registered certificates representing Trust Notes;

2.11.3.2 the Trustee shall request the Clearing Agency to deliver the global certificate representing Trust Notes to the Trustee and the Trustee shall thereupon reduce the holdings of such Clearing Agency on the register maintained hereunder to nil in respect of the Trust Notes represented by such global certificate;

2.11.3.3 the Issuer shall issue or cause to be issued, in accordance with and subject to the provisions of this Indenture, in exchange for such global certificate, Trust Notes of a Series in definitive form in an aggregate amount equal to the amount of such global certificate registered in the names of the Participants as advised by the Clearing Agency in accordance with their proportionate interest in such global certificate as recorded in the records maintained by such Clearing Agency as at the date of the issue of the Trust Notes in definitive form; and

2.11.3.4 after such replacement of such global certificate by definitive Trust Notes, all payments in respect of such Trust Notes in definitive form shall be made to the registered holders thereof in accordance with the terms and conditions of such Trust Notes in definitive form and the provisions of this Indenture and in all other respects such registered holders shall be the holders thereof for all purposes hereunder.

2.11.4 All expenses of the Trustee and any applicable Clearing Agency relating to this section 2.11 shall be paid by the Issuer.

2.11.5 Any notice required or permitted to be given to any beneficial holder of Trust Notes while such Trust Notes are represented by a global certificate held by, or on behalf of, an applicable Clearing Agency as part of the Book-Entry System, shall be provided to or as directed by such Clearing Agency.

2.11.6 It is hereby acknowledged that in making the determination as to the percentage interest of a Participant in a global certificate, the Trustee shall be entitled to rely solely upon the records therefor maintained by any applicable Clearing Agency and confirmed in writing to the Trustee by such Clearing Agency.

2.11.7 The Issuer shall not be responsible for any actions, inactions or omissions on the part of any Clearing Agency and/or the Participants under this Indenture or under any agreements, service rules or procedures entered into between an applicable Clearing Agency and each Participant and shall not be liable to registered holders for any such actions, inactions or omissions by any Clearing Agency and/or the Participants which adversely affect a Person’s beneficial interest in Trust Notes.

2.12 Payment of Principal and Interest in Respect of Trust Notes

2.12.1 Subject to section 2.12.4 and the specific terms applicable to a Series of Trust Notes, payment of the principal of the Trust Notes will be made by cheque or electronic transfer of funds to the respective Holders thereof in lawful money of the United States against surrender thereof by the respective Holders thereof at the principal office of the Trustee in Calgary, Alberta.

2.12.2 Subject to sections 2.12.3 and 2.12.4 and the specific terms applicable to a Series of Trust Notes, as the interest on Trust Notes becomes due (except interest payable on the maturity date which may be paid upon presentation and surrender of such Trust Notes for payment), the Issuer shall, on each date on which interest on such Trust Notes becomes due, effect an electronic transfer or forward, or cause to be forwarded, a cheque by first class mail, postage prepaid (or in the event of a mail service interruption by such other means as the Trustee and the Issuer shall determine to be appropriate), for such interest (less any tax required or permitted by law and the specific terms applicable to a Series of Trust Notes to be deducted) to such Holder and payable to such Holder and negotiable at par at each of the places at which interest upon such Trust Notes is payable. Any electronic transfer instructions received by the Trustee shall remain in effect until revoked by the Holder. The forwarding of such cheque or electronic funds shall satisfy and discharge the liability for the interest on such Trust Notes to the extent of the sum represented thereby (plus the amount of any tax deducted as aforesaid) unless such cheque is not paid on presentation or is lost or destroyed or such electronic funds are not received on or prior to the applicable payment date. In the event of the non-receipt of any such cheque by a Holder, or the loss or destruction thereof, the Issuer, upon being furnished with evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, shall issue or cause to be issued to such Holder a replacement cheque for the amount of such cheque. In the event of the non-receipt of any electronic funds by a Holder, the Issuer, upon being furnished with evidence of such non-receipt and indemnity reasonably satisfactory to it, shall forward or cause to be forwarded to such Holder a replacement electronic transfer for the amount initially transferred and not received.

2.12.3 Where Trust Notes are registered in more than one name, the principal and interest from time to time payable in respect thereof shall be paid by cheque or electronic transfer of

funds payable to the order of all such Holders, unless the Issuer has received written instructions from them to the contrary, and the receipt of any one of such Holders therefor shall be a valid discharge to the Trustee, any registrar of Trust Notes, the Issuer and any Paying Agent.

2.12.4 If Trust Notes of a Series are registered in the name of a Clearing Agency or its nominee, the principal and interest from time to time payable (subject to any amounts withheld in accordance with customary practices and procedures of the Trustee or the Clearing Agency) in respect thereof shall be paid by delivery of a cheque or electronic transfer of funds payable to the order of the Clearing Agency or its nominee, as the case may be, and the receipt of the Clearing Agency or its nominee, as the case may be, therefor shall be a valid discharge to the Trustee, any registrar of Trust Notes, the Issuer and any Paying Agent, who shall be entitled to rely upon the Clearing Agency and the Participants to ensure that funds are advanced to beneficial holders of Trust Notes.

2.13 Ownership of Trust Notes

2.13.1 The Person in whose name any Trust Notes are registered shall be deemed to be the owner thereof for all purposes of this Indenture, except for purposes of any withholding tax in which case the beneficial owner of the Trust Notes will be deemed to be the owner, and payment of or on account of the principal of, and interest on, such Trust Notes shall be made only to or upon the order in writing of the registered holder thereof and such payment shall be a complete discharge to the Trustee, any registrar of Trust Notes, the Issuer and any Paying Agent for the amounts so paid.

2.13.2 The Holder for the time being of any Trust Notes shall be entitled to the principal and interest evidenced by such Trust Notes, free from all equities or rights of set-off or counterclaim between the Issuer and the original or any intermediate Holder thereof (except any equities of which the Issuer is required to take notice by law or any rights of set-off or counterclaim which may be specifically set out in the terms of any Series of Trust Notes) and all Persons may act accordingly and a transferee of a Trust Note shall, after the appropriate form of transfer is lodged with the Trustee or other registrar of Trust Notes and upon compliance with all other conditions in that behalf required by this Indenture or by any conditions contained in such Trust Notes or by law, be entitled to be entered on the appropriate register or on any one of the appropriate registers as the owner of such Trust Notes free from all equities or rights of set-off or counterclaim between the Issuer and such Holder’s transferor or any previous Holder thereof, save in respect of equities of which the Issuer is required to take notice by statute or by order of a court of competent jurisdiction.

2.14 Exchange of Trust Notes

2.14.1 In the event that the Trust Notes of a Series are not held in the Book-Entry System, Trust Notes of any denomination may be exchanged for Trust Notes of any other authorized denomination or denominations, any such exchange to be for an equivalent aggregate principal amount and Series. Exchanges of Trust Notes may only be made at the principal office of the Trustee in the City of Calgary, Alberta. Any Trust Notes tendered for exchange shall be surrendered to the Trustee and shall be cancelled. The Issuer shall execute, and the Trustee shall certify, all Trust Notes necessary to carry out such exchanges.

2.14.2 Except as otherwise provided herein, upon any exchange of Trust Notes of any denomination for Trust Notes of any other authorized denominations and upon any transfer of Trust Notes, the Trustee or other registrar of Trust Notes may make a sufficient charge to

reimburse it for any stamp tax, security transfer tax or other governmental charge required to be paid, and in addition a reasonable charge for its services for Trust Notes exchanged or transferred, and payment of such charges shall be made by the party requesting such exchange or transfer as a condition precedent thereto.

2.14.3 Notwithstanding the foregoing, no charge to the Holder (other than for insurance on any Trust Notes forwarded by mail) shall be made by the Trustee, any registrar of Trust Notes or the Issuer

2.14.3.1 for any exchange, registration or transfer of any Trust Notes applied for within a period of 30 days from the date of issue thereof; or

2.14.3.2 for any exchange, after such period, of Trust Notes for Trust Notes of the same Series in lesser denominations;

provided that the Trust Notes surrendered for exchange shall not have been issued as a result of any previous exchange, other than an exchange pursuant to section 2.14.3.1 or section 3.8.

2.14.4 None of the Issuer, the Trustee or any other registrar of Trust Notes shall be required to make exchanges of Trust Notes on any interest payment date, during the 10 Business Days immediately preceding any interest payment date or from the Selection Date to the date that notice of redemption is mailed.

2.15 Replacement of Trust Notes

If any of the Trust Notes of a Series shall become mutilated or be lost, stolen or destroyed and in the absence of notice that such Trust Notes have been acquired by a bona fide purchaser, the Issuer shall issue, and thereupon the Trustee shall certify and deliver, new Trust Notes of the same Series upon surrender and cancellation of the mutilated Trust Notes, or, in the case of lost, stolen or destroyed Trust Notes, in lieu of and in substitution for the same, and the substituted Trust Notes shall be in a form approved by the Trustee and shall, subject to the terms of the applicable Series, be entitled to the benefits of this Indenture equally with all other Trust Notes issued or to be issued hereunder. In case of loss, theft or destruction, the applicant for new Trust Notes shall furnish to the Issuer and to the Trustee such evidence of such loss, theft or destruction as shall be satisfactory to them in their discretion and shall also furnish an indemnity in amount and form satisfactory to them in their discretion and any other documents that may be required. The applicant shall pay all expenses incidental to the issuance of any such new Trust Notes.

2.16 Interim Trust Notes

2.16.1 Pending delivery to the Trustee of definitive Trust Notes, the Issuer may execute in lieu thereof (but subject to the same provisions, conditions and limitations as herein set forth), and the Trustee may certify, interim printed, mimeographed or typewritten Trust Notes of a Series (“Interim Trust Notes”), in such form and in such denominations as may be approved by the Trustee and by the Administrative Agent on behalf of the Issuer by any one of the Authorized Officers of the Administrative Agent (whose certification or signature, either manual or in facsimile, as the case may be, on any such Interim Trust Notes shall be conclusive evidence of such approval) entitling the Holders thereof to definitive Trust Notes of the same Series in any authorized denominations when the same are ready for delivery, without expense to such Holders, but the total amount of Interim Trust Notes so issued shall not exceed the aggregate principal amount of Trust Notes of such Series authorized to be issued hereunder. Forthwith after the

issuance of any such Interim Trust Notes, the Issuer shall cause to be prepared the appropriate definitive Trust Notes of such Series for delivery to the Holders of such Interim Trust Notes.

2.16.2 Interim Trust Notes which have been duly issued shall, until exchanged for definitive Trust Notes, entitle the Holders thereof to rank for all purposes as Holders, and otherwise in respect of this Indenture to the same extent and in the same manner as though such exchange had actually been made. When exchanged for definitive Trust Notes, such Interim Trust Notes shall forthwith be cancelled by the Trustee. Any interest paid upon Interim Trust Notes shall be noted thereon by the Paying Agent at the time of payment unless paid by cheque to the Holders thereof.

2.17 Option of Holder as to Place of Payment

Except as otherwise provided herein, all sums which may at any time become payable, whether on the maturity date, on redemption or on a declaration by the Trustee pursuant to section 6.3 or otherwise, on account of any Trust Notes or any interest shall be payable at the option of the Holder at any of the places at which the principal of and interest on such Trust Notes are payable.

2.18 Payment Agreements for Trust Notes

Notwithstanding anything contained herein, the Issuer may enter into an agreement with a Holder of Trust Notes or with the Person for whom such Holder is acting as nominee providing for the payment to such Holder of the principal, interest, redemption price, if any, on such Trust Notes, together with any other amounts payable with respect thereto, at a place or places other than the place or places specified herein and in such Trust Notes as the place or places for such payment. Any payment of the principal, interest, redemption price, if any, on any such Trust Notes, together with any other amounts payable with respect thereto, at such other place or places pursuant to such agreement shall, notwithstanding any other provision of this Indenture, be valid and binding on the Issuer, the Trustee and such Holder of Trust Notes. The Issuer shall provide written notice to the Trustee of the existence and terms of any payment agreement between the Issuer and any Holder.

2.19 ERISA Matters

2.19.1 Subject to the restrictions in this Section 2.19, the Trust Notes may be held by (i) plans that are subject to the fiduciary responsibility provisions of ERISA or the provisions of Section 4975 of the Code and entities deemed to hold plan assets of the foregoing (such plans and entities, “Plans”) and (ii) plans that are subject to provisions under federal, state or other laws (“Similar Law”) that are substantially similar to the fiduciary responsibility provisions of ERISA or the prohibited transaction provisions of ERISA and/or Section 4975 of the Code (such plans, “Similar Law Plans”). A fiduciary of any Plan or Similar Law Plan shall determine that the purchase, holding, redemption or exchange of the Trust Notes or an interest therein is consistent with its fiduciary duties and will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or a violation under any applicable Similar Law. Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of Plans (as well as those plans that are not subject to ERISA but which are subject to Section 4975 of the Code) and certain persons (“parties in interest” or “disqualified persons”) having certain relationships to such Plans, unless a statutory or administrative exemption is applicable to the transaction. There can be no assurance that any administrative or statutory exemption will be available with respect to any particular transaction involving the Trust Notes. A party in interest or disqualified person who engages in a prohibited transaction

may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code.

2.19.2 Under a regulation issued by the U.S. Department of Labor, 29 CFR Section 2510.3-101 (as effectively modified by Section 3(42) of ERISA)(the “Regulation”), the assets of the Trust would be treated as plan assets of a Plan for the purposes of ERISA and the Code only if the Plan acquired an “equity interest” in the Trust and none of the exceptions to “plan assets” contained in the Regulation was applicable. An equity interest is defined under the Regulation as an interest other than an instrument which is treated as indebtedness under applicable local law and which has no substantial equity features. The Trust believes that as of the date hereof, the Trust Notes should be treated as indebtedness of the Trust without substantial equity features for purposes of the Regulation, but there is no certainty that the U.S. Department of Labor or a court would agree with that position. This determination is based upon the traditional debt features of the Trust Notes, including the reasonable expectation of purchasers of the Trust Notes that the Trust Notes will be repaid when due. The purchasers and subsequent transferees of the Trust Notes or any interest therein will be deemed to have acknowledged by its purchase, holding, redemption or exchange thereof that the debt treatment of the Trust Notes for ERISA purposes could change subsequent to the date hereof if the Trust incurs losses. In the event of a withdrawal or downgrade to below investment grade of the rating of the Trust Notes or a characterization of the Trust Notes as other than indebtedness under applicable local law, the transfer and subsequent acquisition of the Trust Notes or interest therein by a Plan is prohibited.

2.19.3 Unless a statutory or administrative exemption is applicable, the purchase and, in certain cases, the holding of securities by a Plan with respect to which (i) the Trust or any of its affiliates or (ii) any underwriter, dealer or agent selling the securities or any of their affiliates is a party in interest or disqualified person could constitute a prohibited transaction. Accordingly, each purchaser and subsequent transferee of the Trust Notes or any interest therein will be deemed to have represented by its purchase, holding, redemption or exchange thereof that either (i) it is not, and is not acting on behalf of, any Plan or Similar Law Plan or (ii) its purchase, holding, redemption or exchange of the Trust Notes or any interest therein will not constitute or result in a nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code because such purchaser and subsequent transferee relied on an available prohibited transaction exemption, all of the conditions of which are satisfied, or is not in violation of any applicable Similar Law. Each purchaser and subsequent transferee of the Trust Notes or any interest therein will be deemed to have acknowledged by its purchase, holding, redemption or exchange thereof that neither Plans nor Similar Law Plans may acquire the Trust Notes at any time that the ratings on the Trust Notes are below investment grade or the Trust Notes have been characterized as other than indebtedness for applicable local law purposes.

2.19.4 The purchasers and subsequent transferees of the Trust Notes or any interest therein will be deemed to have acknowledged by its purchase, holding, redemption or exchange thereof that the sale of any securities to a Plan or Similar Law Plan is in no respect a representation by the Trust, or by any underwriter, dealer or agent selling the securities, that such an investment meets all of the legal requirements with respect to investments by any particular Plan or Similar Law Plan or that such an investment is appropriate for any particular Plan or Similar Law Plan.

2.19.5 References to holder, purchaser or transferee of Trust Notes in this Section 2.19 include reference to a beneficial holder, owner, purchaser or transferee of Trust Notes.

ARTICLE 3

REDEMPTION AND PURCHASE FOR CANCELLATION OF TRUST NOTES

3.1 Redemption of Trust Notes at Option of Issuer

The Issuer shall have the right at its option to redeem either in whole at any time or in part from time to time prior to maturity Trust Notes issued hereunder of any Series which by their terms are made so redeemable (subject, however, to any applicable law restricting the redemption of Trust Notes of such Series) at such rates of premium, if any, and at such date or dates as shall have been determined at the time of the issue of such Trust Notes and as shall be expressed in such Trust Notes and/or supplemental indenture providing for the issue thereof.

3.2 Partial Redemption of Trust Notes

If less than all the Trust Notes of a Series are to be redeemed pursuant to section 3.1, the Issuer shall, at least 15 days prior to the date that notice of redemption is given, notify the Trustee of its intention to redeem the aggregate principal amount of such Series to be redeemed. The Trust Notes to be redeemed shall be selected by the Trustee in such manner as may be described in the applicable Series of Trust Notes and/or any supplemental indenture, or in such other manner as the Trustee may consider equitable. The day the Trustee makes such selection shall be referred to for the purpose of sections 2.10.4.2 and 2.14 as the “Selection Date”. For this purpose, the Trustee may make, and from time to time amend, regulations with regard to the manner in which such Trust Notes may be so selected and regulations so made shall be valid and binding upon all Holders of Trust Notes notwithstanding the fact that, as a result thereof, one or more of such Trust Notes become subject to redemption in part only.

3.3 Notice of Redemption

Notice of any intention to redeem any Trust Notes of a Series shall be given by or on behalf of the Issuer to the Holders of such Series in accordance with the terms contained in such Series or any supplemental indenture in respect thereof.

3.4 Trust Notes Due on Redemption Dates

3.4.1 Upon notice having been given as aforesaid, the Trust Notes so called for redemption shall thereupon become due and payable at the applicable redemption price and on the redemption date specified in such notice, in the same manner and with the same effect as if it were the maturity date specified in such Trust Notes, notwithstanding anything contained therein or herein to the contrary, and from and after such redemption date, if the moneys necessary to redeem such Trust Notes shall have been deposited as hereinafter provided and an Officer’s Certificate, affidavit or other proof satisfactory to the Trustee as to the mailing of such notices shall have been delivered to the Trustee, such Trust Notes shall no longer be considered outstanding hereunder and interest upon such Trust Notes shall cease to accrue after such date.

3.4.2 If any question shall arise as to whether notice of redemption or deposit of the redemption moneys has been given or made as provided above, such question shall be decided by the Trustee whose decision shall be final and binding upon all parties in interest.

3.5 Deposit of Redemption Moneys

Upon Trust Notes having been called for redemption, the Issuer shall deposit with the Trustee, on or before the redemption date fixed in the relevant notice of redemption, such sums as may be sufficient to pay the redemption price of the Trust Notes to be redeemed, together with accrued interest, if any, and the estimated charges and expenses to be incurred in connection with such redemption. From the sums so deposited, the Trustee shall pay or cause to be paid to the Holders of the Trust Notes called for redemption, upon surrender of such Trust Notes, the applicable redemption price and interest, (less any applicable withholding taxes, to the extent required or permitted by law and the specific terms applicable to a Series of Trust Notes) to which they are respectively entitled on redemption.

3.6 Failure to Surrender Trust Notes Called for Redemption

If the Holder of any Trust Notes called for redemption shall, within 30 days from the date fixed for redemption, fail to surrender any of such Trust Notes or shall not within such time accept payment of the redemption price payable in respect thereof or give such receipt therefor, if any, as the Trustee may require, such redemption price shall be set aside by the Trustee in trust for such Holder in a bank account and such setting aside shall for all purposes be deemed a payment to the Holder of the sum so set aside, and to that extent the Holder shall have no right except to receive payment out of the moneys so paid and deposited, upon surrender of his Trust Notes, of the redemption price of such Trust Notes without interest thereon.

3.7 Surrender of Trust Notes for Cancellation

If the principal moneys due upon any Trust Notes shall become payable by redemption or otherwise before the maturity date, the Person presenting such Trust Notes for payment must surrender the same for cancellation, the Issuer nevertheless paying or causing to be paid the interest accrued and unpaid thereon in accordance with the terms of such Trust Notes (computed on a per diem basis if the date fixed for payment is not a scheduled interest payment date).

3.8 Purchase of Trust Notes for Cancellation

Subject to such restrictions on purchase as may be set forth in any Trust Notes of a Series or in any supplemental indenture under which Trust Notes of a Series may be issued, at any time when the Issuer is not in default hereunder, the Issuer may purchase Trust Notes in the market or by private contract at any price.

3.9 Cancellation of Trust Notes

All Trust Notes redeemed and all Trust Notes purchased under this Article 3 shall forthwith be delivered to the Trustee and shall be cancelled by it and will not be reissued or resold, and except as may be provided in the Trust Notes or any supplemental indenture in respect thereof, no Trust Notes shall be issued in substitution therefor.

ARTICLE 4

SUBORDINATION OF TRUST NOTES

4.1 Trust Notes Subordinated to Issuer Senior Indebtedness

4.1.1 The Issuer covenants and agrees, and each Holder of Trust Notes, by the acceptance thereof, likewise covenants and agrees, that the indebtedness represented by the Trust Notes and the payment of the principal of and interest on each and all of the Trust Notes is hereby expressly

subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of Issuer Senior Indebtedness.

4.1.2 In the event (a) of any insolvency or bankruptcy proceedings or any receivership, liquidation, reorganization or other similar proceedings in respect of the Issuer or a substantial part of its property, or of any proceedings for liquidation, dissolution or other winding up of the Issuer, whether or not involving insolvency or bankruptcy, or (b) subject to the provisions of Section 4.2 that (i) a default shall have occurred with respect to the payment of principal of or interest on or other monetary amounts due and payable on any Issuer Senior Indebtedness, or (ii) there shall have occurred an event of default (other than a default in the payment of principal or interest or other monetary amounts due and payable) in respect of any Issuer Senior Indebtedness, as defined therein or in the instrument under which the same is outstanding, permitting the holder or holders thereof to accelerate the maturity thereof (with notice or lapse of time, or both), and such event of default shall have continued beyond the period of grace, if any, in respect thereof, and, in the cases of subclauses (i) and (ii) of this clause (b), such default or event of default shall not have been cured or waived or shall not have ceased to exist, or (c) that the principal of and accrued interest on the Trust Notes of any series shall have been declared due and payable pursuant to Section 6.3 and such declaration shall not have been rescinded and annulled as provided in Section 6.4, then:

4.1.2.1 the holders of all Issuer Senior Indebtedness shall first be entitled to receive payment of the full amount due thereon, or provision shall be made for such payment in money or money’s worth, before the Holders of any of the Trust Notes are entitled to receive a payment on account of the principal of or interest on the indebtedness evidenced by the Trust Notes, including, without limitation, any payments made pursuant to Article 3;

4.1.2.2 any payment by, or distribution of assets of, the Issuer of any kind or character, whether in cash, property or securities, to which the Holders of any of the Trust Notes or the Trustee would be entitled except for the provisions of this Article shall be paid or delivered by the person making such payment or distribution, whether a trustee in bankruptcy, a receiver, receiver and manager or liquidating trustee or otherwise, directly to the holders of such Issuer Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Issuer Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of such Issuer Senior Indebtedness held or represented by each, to the extent necessary to make payment in full of all Issuer Senior Indebtedness remaining unpaid after giving effect to any concurrent payment or distribution (or provision therefor) to the holders of such Issuer Senior Indebtedness, before any payment or distribution is made to the holders of the indebtedness evidenced by the Trust Notes or to the Trustee under this instrument; and

4.1.2.3 in the event that, notwithstanding the foregoing, any payment by, or distribution of assets of, the Issuer of any kind or character, whether in cash, property or securities, in respect of principal of or interest on the Trust Notes or in connection with any repurchase by the Issuer of the Trust Notes, shall be received by the Trustee or the Holders of any of the Trust Notes before all Issuer Senior Indebtedness is paid in full, or provision made for such payment in money or money’s worth, such payment or distribution in respect of principal of or interest on the Trust Notes or in connection with any repurchase by the Issuer of the Trust Notes shall be paid over to the holders of such Issuer Senior Indebtedness or their representative or representatives or to the trustee or

trustees under any indenture under which any instruments evidencing any such Issuer Senior Indebtedness may have been issued, ratably as aforesaid, for application to the payment of all Issuer Senior Indebtedness remaining unpaid until all such Issuer Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or distribution (or provision therefor) to the holders of such Issuer Senior Indebtedness.

4.2 Disputes with Holders of Certain Issuer Senior Indebtedness

Any failure by the Issuer to make any payment on or perform any other obligation under Issuer Senior Indebtedness, other than any indebtedness incurred by the Issuer or assumed or guaranteed, directly or indirectly, by the Issuer for money borrowed (or any deferral, renewal, extension or refunding thereof) or any indebtedness or obligation as to which the provisions of this Section shall have been waived by the Issuer in the instrument or instruments by which the Issuer incurred, assumed, guaranteed or otherwise created such indebtedness or obligation, shall not be deemed a default or event of default under Section 4.1.2(b) if (a) the Issuer shall be disputing its obligation to make such payment or perform such obligation and (b) either (i) no final judgment relating to such dispute shall have been issued against the Issuer which is in full force and effect and is not subject to further review, including a judgment that has become final by reason of the expiration of the time within which a party may seek further appeal or review, and (ii) in the event of a judgment that is subject to further review or appeal has been issued, the Issuer shall in good faith be prosecuting an appeal or other proceeding for review and a stay of execution shall have been obtained pending such appeal or review.

4.3 Subrogation

Subject to the payment in full of all Issuer Senior Indebtedness, the Holders of the Trust Notes shall be subrogated (equally and ratably with the holders of all obligations of the Issuer which by their express terms are subordinated to Issuer Senior Indebtedness of the Issuer to the same extent as the Trust Notes are subordinated and which are entitled to like rights of subrogation) to the rights of the holders of Issuer Senior Indebtedness to receive payments or distributions of cash, property or securities of the Issuer applicable to the Issuer Senior Indebtedness until all amounts owing on the Trust Notes shall be paid in full, and as between the Issuer, its creditors other than holders of such Issuer Senior Indebtedness and the Holders, no such payment or distribution made to the holders of Issuer Senior Indebtedness by virtue of this Article that otherwise would have been made to the Holders shall be deemed to be a payment by the Issuer on account of such Issuer Senior Indebtedness, it being understood that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of Issuer Senior Indebtedness, on the other hand.

Notwithstanding the provisions of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of moneys to or by the Trustee, or the taking of any other action by the Trustee, unless and until the Trustee shall have received written notice thereof mailed or delivered to the Trustee from the Issuer, any Holder, any paying agent or the holder or representative of any class of Issuer Senior Indebtedness; provided that if at least three Business Days prior to the date upon which by the terms hereof any such moneys may become payable for any purpose (including, without limitation, the payment of the principal or interest on any Trust Note) the Trustee shall not have received with respect to such moneys the notice provided for in this Section, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary that may be received by it within three Business Days prior to or on or after such date.

If any Event of Default has occurred and is continuing, the Trustee may in its discretion and shall upon receipt of a Holders’ Request, subject to section 6.4, by notice in writing to the Issuer, declare the principal of, and interest on, the Trust Notes of any Series then outstanding and any other moneys payable hereunder to be due and payable and the same shall forthwith become immediately due and payable to the Trustee, notwithstanding anything contained therein or herein to the contrary, and the Issuer shall pay forthwith to the Trustee for the benefit of the Holders of such Series the principal of, and accrued and unpaid interest (including interest on amounts in default) on, such Trust Notes and all other moneys payable hereunder, together with subsequent interest thereon at the rate borne by such Trust Notes from the date of such declaration until payment is received by the Trustee.

Indenture, notwithstanding that the Holders of not less than a majority of the aggregate principal amount of the Trust Notes then outstanding are not present in person or by proxy at such adjourned meeting.

Any remuneration so paid by the Trustee shall be repaid in accordance with section 5.4.

11.5.4 The Trustee may act and rely and shall be protected in acting and relying in good faith on the opinion or advice or information obtained from any counsel, auditors, accountants, appraisers or other expert or advisers, whether retained or employed by the Trustee in accordance with section 11.5.3 or by the Issuer, in relation to any manner arising in the performance of its duties under the Trust Indenture.

11.14 Compliance with Anti-Money Laundering Legislation

The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. The Issuer hereby agrees that if any account to be opened, or interest to be held, by the Trustee in connection with this Indenture, for or to the credit of the Issuer, is intended to be used by or on behalf of a third party, the Issuer will complete and execute forthwith a declaration in the Trustee’s prescribed form as to the particulars of such third party.
