The aggregate principal amount of Notes authorized to be issued under this Note Indenture shall be unlimited. Notes may be issued in series as provided in section 2.2 and section 2.18 but only on the terms and subject to the conditions of this Note Indenture.

2.2 Terms of Series A Notes

(a) The initial series of Notes shall be designated as “Series A Notes”. The Series A Notes shall be dated as of the Issue Date, shall mature on the Maturity Date, shall bear interest from and including the Issue Date at the Interest Rate payable, after as well as before maturity and after as well as before default and judgment, with interest on amounts not paid when due at the same rate, payable on each Interest Payment Date for the Interest Period relating to such Interest Payment Date, shall be redeemable prior to maturity to the extent and in the manner set forth in Article 4, and shall be subordinated to all Senior Indebtedness as provided in Article 5. The Series A Notes will rank equally in right of payment without discrimination or preference in the case of any Creditor Proceedings.

(b) Series A Notes in the aggregate principal amount of $125,000,000.00 shall be executed by the Corporation and, forthwith after such execution, shall be delivered to the Trustee and shall be certified by the Trustee and delivered to or to the order of the Corporation pursuant to a Written Direction of the Corporation which will contain the applicable registration instructions for the Series A Notes.

(c) The Directors may from time to time authorize the issue of Series A Notes (the “Additional Series A Notes”) hereunder in addition to the Series A Notes referred to in subsection (b) above. Additional Series A Notes shall mature on the same date and bear the same rate of interest as the Series A Notes issued pursuant to subsection (b) above, but may be limited to such aggregate principal amount, bear such date or dates, be payable at such place or places and in Canadian or such other currency or

-8-

currencies and contain such other terms or provisions not inconsistent herewith as the Corporation may determine.

(d) All Series A Notes, including any Additional Series A Notes, shall be issued in the minimum denomination of $100.00 and for amounts above such minimum only in integral multiples of $1.00.

(e) Before the issue of any Additional Series A Notes, the Corporation shall execute and deliver to the Trustee a Certified Resolution of the Directors authorizing the issue of the same.

(f) When Additional Series A Notes shall have been authorized as aforesaid, the same may from time to time be executed by the Corporation and delivered to the Trustee and, subject to subsection (h) below, shall be certified by or on behalf of the Trustee and delivered by it to or to the order of the Corporation pursuant to a Written Direction of the Corporation upon receipt by the Trustee of the following:

(i) a Certified Resolution of the Directors authorizing certification and delivery of a specified principal amount of such Additional Series A Notes;

(ii) a written request of the Corporation for the certification and delivery of such Additional Series A Notes; and

(iii) such other documents as the Trustee may reasonably request.

(g) No Additional Series A Notes shall be certified or delivered hereunder if, to the knowledge of the Trustee, an Event of Default shall have occurred and be continuing and shall not have been waived in accordance with section 6.10.

2.3 Payment of Interest

(a) Subject to subsections (b) and (c) below, (and except at maturity, when interest shall be paid upon the surrender of any series of Notes for payment), the Corporation shall, at least three days prior to each Interest Payment Date in respect of such series of Notes, cause to be sent by prepaid ordinary mail to each Holder a cheque or by other transfer of funds by such means as may be considered appropriate by the Trustee for the amount of interest to be paid on the Interest Payment Date (less any Canadian Taxes required by law to be withheld or deducted therefrom) payable to the order of the Holder and addressed to it at its last address or account, as the case may be, appearing on the register, unless the Holder otherwise directs. In the case of joint Holders, the cheque or other such transfer of funds shall be payable or issued to the order of all such joint Holders and addressed to them at the last address or account appearing on the register, as the case may be, unless such joint Holders otherwise direct. If more than one address or account appears on the register in respect of such joint Holders, the cheque or other such transfer of funds, as the case may be, shall be mailed or delivered, as the case may be, to the first address or account so appearing. In the event of non-receipt by the Holder of any cheque or funds for interest, the Corporation will cause to be issued to the Holder a replacement cheque or other such replacement transfer of funds for like amount upon being furnished with such evidence of non-receipt as it and the Trustee shall reasonably require and upon the Corporation and the Trustee being indemnified to its satisfaction, acting reasonably. Concurrent with the mailing of such funds to each Holder, the Corporation shall provide evidence of such payment to the Trustee.

(b) The Corporation may extend the payment of interest by extending the Interest Payment Date in accordance with section 2.4 and shall be deemed to so defer whenever it fails to pay interest under subsection (a) or (c).

(c) The Corporation may, in its discretion, elect to pay any interest, including Deferred Interest, by making a Share Payment Election in accordance with section 2.6.

2.4 Deferral of Interest Payment Date

The Corporation may at any time and from time to time defer the payments of interest payable on any Interest Payment Date for up to 27 consecutive months (a “Deferral Period”) commencing on any particular Interest Payment Date and

-9-

interest that was otherwise due on such particular Interest Payment Date and such interest that accrues during a Deferral Period is called Deferred Interest. Such right to defer shall be deemed to be exercised whenever the Corporation fails to pay interest without further or other act by the Corporation, and this section 2.4 shall apply whenever Deferred Interest is unpaid for whatever reason. Notwithstanding the above, no Deferral Period may exceed 27 consecutive months from the commencement of such Deferral Period, as last extended, or extend beyond the Maturity Date or, in the case of a Share Payment Election in respect of the Maturity Amount, the Share Delivery Date in respect of such Maturity Amount (the “Payment Date”). The Corporation may, at any time during a Deferral Period, commence a new Deferral Period for up to 27 consecutive months, subject to the terms described in this Note Indenture. There may be multiple Deferral Periods of various lengths, each of up to 27 consecutive months, throughout the term of the Notes, but none of the Deferral Periods may extend beyond the Payment Date. During a Deferral Period, interest will accrue but will not compound. All Deferred Interest shall be paid on the Interest Payment Date at the end of such Deferral Period, as last extended and, in any event, no later than the Payment Date. No interest payments will be required to be made during a Deferral Period except at the end thereof, as last extended.

2.5 Notice of Deferral

The Corporation shall give the Holders and the Trustee written notice of its initiation of any Deferral Period, and any extensions thereof, at least 21 business days prior to the earlier of: (i) the next succeeding Interest Payment Date; or (ii) the date upon which the Corporation is required to give notice to any applicable regulatory body or to the Holders on the Interest Accrual Date or Interest Payment Date, in each case with respect to interest payments the payment of which is being deferred. Failure to give such notice shall not affect the validity of the initiation of any Deferral Period.

2.6 Share Payment Election

(a) The Corporation may from time to time and whether or not an Event of Default has occurred, in accordance with the provisions hereof, elect (each, a “Share Payment Election”):

(i) to satisfy its obligation to pay any interest, including Deferred Interest on any Interest Payment Date (an “Interest Amount”), by delivering Common Shares; or

(ii) to satisfy its obligation to pay the principal amount of the Notes plus accrued and unpaid interest thereon on the Maturity Date (a “Maturity Amount”), by delivering Common Shares.

(b) The Corporation shall make a Share Payment Election by delivering written notice (the “Share Election Notice”) to the Trustee in accordance with this section 2.6, subject to complying with applicable securities laws and other laws and to obtaining all appropriate regulatory approvals.

(c) In the case of a Share Payment Election in respect of the payment of an Interest Amount, the Share Election Notice shall include: (i) the aggregate Interest Amount (not exceeding the amount of interest, including Deferred Interest, payable in respect of the Notes on such Interest Payment Date) that is being satisfied through the issuance of Common Shares; (ii) the proportion of such Interest Amount that is being satisfied through the issuance of Common Shares, if any; and (iii) the Share Payment Amount.

(d) In the case of a Share Payment Election in respect of the payment of a Maturity Amount: (i) the Share Election Notice shall include the aggregate Maturity Amount (not exceeding the principal amount plus accrued and unpaid interest thereon payable in respect of the Notes on the Maturity Date) that is being satisfied through the issuance of Common Shares; (ii) the Corporation shall deliver such Share Election Notice at least 60 days prior to the Maturity Date; and (iii) the Share Payment Amount.

(e) Upon receipt of a Share Election Notice:

(i) The Trustee shall be required to subscribe for and purchase from the Corporation, on behalf of the Holders of the Notes (or the series of Notes in respect of which such payment is being made, as the case may be), that number of Common Shares that is the quotient obtained by dividing the amount of the Interest Amount or the Maturity Amount, as the case may be, by the Share Payment Amount in respect of such Common Shares.

-10-

(ii) Not later than the Interest Payment Date in respect of which such Share Payment Election is made, or on a date at least 60 days prior to the Maturity Date designated by the Corporation in a Share Payment Election in respect of the payment of a Maturity Amount, as the case may be (the “Share Delivery Date”), the Corporation and the Trustee, on behalf of the Holder, shall enter into a customary purchase agreement (a “Share Purchase Agreement”) and shall comply with all applicable laws, including the securities laws of Canada and the rules and regulations of any stock exchange on which the Common Shares are then listed. The Corporation shall pay all fees and expenses in connection with the Share Purchase Agreement.

(iii) On the Share Delivery Date:

A. The Corporation shall pay the amount of the Interest Amount or the Maturity Amount, as the case may be, in cash to the Trustee.

B. The Trustee shall hold the Interest Amount or the Maturity Amount, as the case may be, so paid and apply such amount to the payment of the aggregate Share Payment Amount to be paid for all Common Shares to be issued on such Share Delivery Date.

C. Provided that all conditions specified in this Note Indenture and the Share Purchase Agreement to the closing of the sale of Common Shares thereunder have been satisfied, other than the delivery of the shares to be sold thereunder against payment of the aggregate Share Payment Amount, the Corporation shall deliver to the Trustee the Common Shares to be issued on such Share Delivery Date, and a Certificate of the Corporation to the effect that all conditions precedent to such sales, including those set forth in this Note Indenture and the Share Purchase Agreement, have been satisfied. Notwithstanding anything herein contained, the Corporation shall in no case be required to deliver fractional Common Shares to the Trustee in respect of any Share Election Notice. If any fractional interest in a Common Share would, except for the provision of this subsection C, be deliverable to the Trustee, the Corporation shall deliver to the Trustee the next lowest whole number of Common Shares and nothing in this subsection C will be interpreted to entitle the Trustee to any interest, whether legal, beneficial or otherwise, to a number of Common Shares greater than such next lowest number of Common Shares.

D. Upon the receipt of the deliveries specified in subsection C above, the Trustee shall consummate such purchase and the Corporation shall issue such Common Shares to the Trustee against payment to the Corporation by the Trustee of the aggregate Share Payment Amount, less any amount attributable to any fractional Common Share, whereupon the sole right of a Holder of a Note in respect of the Interest Amount or the Maturity Amount, as the case may be, will be to the delivery of such Common Shares by the Trustee in full satisfaction of such Interest Amount or Maturity Amount, as the case may be, and the Holder of such Note will have no further recourse against the Corporation or the Trustee in respect of such Interest Amount or Maturity Amount, as the case may be.

(f) Each Share Election Notice shall provide for the right of the Corporation, by delivering written notice to the Trustee at any time prior to the consummation of the issue and sale of the Common Shares that are the subject of such Share Election Notice, to withdraw the Share Payment Election. Such written notice of withdrawal shall have the effect of withdrawing the obligation of the Trustee to subscribe for Common Shares in respect of such Share Election Notice, and shall obligate the Corporation to pay in cash the Interest Amount on the Interest Payment Date or the Maturity Amount on the Maturity Date, as applicable.

(g) The Corporation shall indemnify and hold harmless the Trustee and the Holders of Notes, and any person who controls any such Holder within the meaning of any applicable securities laws, from and

-11-

against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any such person in connection with defending or investigating any such action or claim) caused by or arising in connection with any Share Payment Election or any withdrawal thereof, except in each case for any losses, claims, damages or liabilities caused by any such person’s gross negligence, wilful default or fraud. If the indemnification provided for in this subsection (g) shall be unavailable to an indemnified person or insufficient in respect of any losses, claims, damages or liabilities referred to herein, then the Corporation shall contribute to the amount paid or payable by such indemnified person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the Corporation and such indemnified person and any other equitable considerations.

2.7 Form and Signatures of Notes

(a) The Notes shall be issued only as fully registered Notes. The Notes (including the certificate of the Trustee endorsed thereon) shall be substantially in the form set forth in Schedule A hereto. The Notes shall bear such distinguishing letters and numbers and such legends as the Corporation shall direct and Trustee may approve and may include a translation into the French language.

(b) The Notes shall be signed (either manually or by facsimile signature) by the President of the Corporation together with one of the following: any Vice President, the Secretary, the Chairman of the Board or the Assistant Secretary of the Corporation. A facsimile signature upon any of the Notes shall, for all purposes of this Note Indenture, be deemed to be the signature of the person whose signature it purports to be and to have been signed at the time such facsimile signature is reproduced; provided, however, that the certification of the Trustee shall not be by facsimile signature. Notwithstanding that any person whose signature, either manual or in facsimile, may appear on a Note is no longer, at the date of this Note Indenture or at the date of such Note or at the date of the certification and delivery thereof, the holder of the office indicated, any such Note shall be valid and binding upon the Corporation and entitled to the benefits of this Note Indenture.

2.8 Certification

(a) No Note shall be issued or, if issued, shall be obligatory or shall entitle the Holder to the benefits of this Note Indenture, until it has been certified by or on behalf of the Trustee substantially in the form set out in Schedule A hereto (or in some other form approved by the Trustee). Such certification on any Note shall be conclusive evidence that such Note is duly issued, is a valid obligation of the Corporation and is entitled to the benefits hereof.

(b) The certificate of the Trustee signed on the Notes shall not be construed as a representation or warranty by the Trustee as to the validity of this Note Indenture or of the Notes or as to the issuance of the Notes and the Trustee shall in no respect be liable or answerable for the use made of the Notes or any of them or the proceeds thereof. The certificate of the Trustee signed on the Notes shall, however, be a representation and warranty by the Trustee that the Notes have been duly certified by or on behalf of the Trustee pursuant to the provisions of this Note Indenture.

2.9 Notes to Rank Pari Passu

The Notes may be issued in such amounts, to such persons, and on such terms not inconsistent with the provisions of this Note Indenture, at par. Each Note as soon as issued or negotiated subject to the terms hereof, shall rank pari passu and shall be equally and proportionately entitled to the benefits hereof (except in respect of interest which shall accrue from the Issue Date of each Note and shall not be deemed to accrue from the same date for all Notes), without discrimination, preference or priority whatever, as if all of the Notes had been issued and negotiated simultaneously.

2.10 Registration of Notes

(a) The Corporation shall, at all times while any Notes are outstanding, cause to be kept at the principal office of the Trustee in the City of Calgary and in such other place or places and by the Trustee or such other registrars, if any, as the Corporation with the approval of the Trustee may designate, registers (“register(s)”) in which shall be entered the names and addresses of the Holders and

-12-

particulars of the Notes held by them respectively and of all transfers of Notes. No transfer of a Note shall be valid unless made by the Holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee, upon compliance with such requirements as the Trustee may prescribe, and unless such transfer shall have been duly entered on one of the appropriate registers or noted on such Note by the Trustee or other registrar.

(b) The registers hereinbefore referred to shall at all reasonable times be open for inspection by the Corporation, the Trustee or any Holder. Every registrar (including the Trustee) shall from time to time when requested so to do by the Corporation, the Trustee or any Holder, furnish the Corporation, Trustee or such Holder with a list of the names and addresses of Holders entered on the register or registers kept by such registrar and showing the principal amount and serial numbers of the Notes held by each such Holder.

(c) The Holder of a Note may at any time and from time to time have such Note transferred at any of the places at which a register is kept pursuant to the provisions of this section 2.10, by surrendering the certificate for such Note together with a duly executed Transfer and complying with such reasonable regulations as the Trustee and/or other registrar may prescribe.

(d) Neither the Corporation nor the Trustee shall be required to transfer or exchange any Notes on any Interest Payment Date or during a period of ten (10) business days immediately preceding any such date.

(e) None of the Trustee, any other registrar or the Corporation shall be charged with notice of or be bound to see to the execution of any trust, whether expressed, implied or constructive, with respect to any Note and the Trustee, any other registrar or the Corporation may transfer any Note on the direction of the Holder thereof, whether named as trustee or otherwise, as though that person were the beneficial owner thereof.

(f) Except in the case of the register required to be kept at the Trustee’s principal office in the City of Calgary, the Corporation with the approval of the Trustee may at any time close any register upon which the registration of any Note appears and transfer the records thereof to another existing register or to a new register and thereafter such Notes shall be deemed to be registered on such existing or new register, as the case may be. Notice of such transfer shall be given to the Holders of such Notes prior to such transfer.

2.11 Persons Entitled to Payment

(a) The Person in whose name any Note shall be registered shall be deemed and regarded as the owner thereof for all purposes of this Note Indenture and payment of or on account of the principal of such Note shall be made only to or upon the order in writing of such Holder thereof and such payment shall be good and sufficient discharge to the Trustee and any registrar and to the Corporation and any paying agent for the amounts so paid.

(b) The Holder for the time being of any Note shall be entitled to the principal monies, and interest evidenced by such Note, free from all equities or rights of set-off or counterclaim between the Corporation and the original or any intermediate Holder thereof and all persons may act accordingly and a transferee of a Note shall, after an appropriate form of Transfer is lodged with the Trustee or other registrar and upon compliance with all other conditions in that behalf required by this Note Indenture or by any conditions contained in such Note or by law, be entitled to be entered on any of the appropriate registers as the owner of such Note free from all equities or rights of set-off or counterclaim between the Corporation and his transferor or any previous Holder thereof, save with respect to equities of which the Corporation is required to take notice by statute or by order of a court of competent jurisdiction.

(c) Delivery by the Corporation to a Holder of a Note of, or the receipt of such Holder for, the principal monies and interest evidenced by such Note, respectively, shall be a good discharge to the Corporation, which shall not be bound to enquire into the title of such Holder, save as ordered by a

-13-

court of competent jurisdiction or as required by statute. Neither the Corporation, the Trustee nor any registrar shall be bound to see to the execution of any trust affecting the ownership of any Note nor be affected by notice of any equity that may be subsisting with respect thereto.

(d) In the case of the death of one or more joint Holders, the principal monies of, and interest on any Notes may be paid to the survivor or survivors of such joint Holders whose receipt thereof shall constitute a valid discharge to the Trustee, any registrar, the Corporation and any paying agent.

2.12 Withholding or Deduction of Canadian Taxes

(a) As between each Holder and the parties hereto, the Holder shall be liable for all Canadian Taxes which may become payable by, on behalf of, or for the account of such Holder in respect of such Notes registered in the Holder’s name.

(b) The Trustee and the Corporation shall provide the other with all the information in its possession necessary for the Corporation or the Trustee to determine the amount of withholding taxes levied under Part XIII of the Tax Act (Canada) and includes any similar Canadian Taxes hereafter levied in addition to or in substitution therefor, and penalties or interest in respect thereof (“Withholding Taxes”) to be remitted on behalf of each non-resident Holder and to otherwise perform its obligations under this section 2.12.

(c) The Corporation and the Trustee shall be entitled to deduct and withhold, from any payment of interest on the Notes that is not made pursuant to a Share Payment Election (a “Cash Interest Payment”), the amount of Withholding Taxes in respect of such Cash Interest Payment.

(d) If the Corporation makes a Cash Interest Payment to the Trustee, on behalf of the Holders, which is substantially contemporaneous with the issue and delivery of Common Shares pursuant to a Share Payment Election in respect of an Interest Amount (a “Non-cash Interest Payment”), the Trustee shall withhold from the Cash Interest Payment the amount of Withholding Tax applicable to both the Cash Interest Payment and the Non-cash Interest Payment to the extent such amount has not been withheld by the Corporation. If a Non-cash Interest Payment is made without a contemporaneous Cash Interest Payment in an amount sufficient to pay all Withholding Tax in relation to such Non-cash Interest Payments or in any other case, if the Corporation or, the Trustee shall receive a demand for or be obliged (on behalf of the Corporation or otherwise) to withhold and remit any Withholding Tax from or in respect of a payment to be made or credited to, on behalf of or for the account of a non-resident Holder, the Corporation shall make arrangements satisfactory to the Trustee whereby the Corporation shall pay to the Trustee on behalf of such non-resident Holder such amount as is equal to the Withholding Tax required to be withheld and remitted by the Trustee, together with such additional amount equal to the Withholding Tax that is or may be with the passage of time, required to be withheld and remitted upon the amount so paid by the Corporation to the Trustee on behalf of such non-resident holder prior to the time required for remittance of such Withholding Tax to the applicable government authorities, and such non-resident Holder shall be liable to pay the Corporation any such amount paid by the Corporation to the Trustee. Any amount paid or deemed to be paid on behalf of a non-resident Holder by the Corporation or the Trustee pursuant to this section 2.12 shall bear interest at the prime rate published from time to time by The Toronto-Dominion Bank (or any successor thereto) (or if at any time a prime rate is not published by such bank, a rate published by a financial institution selected by the Corporation) plus two per cent per annum, calculated daily and compounded monthly from the date of payment or deemed payment. The Trustee shall maintain a separate register showing the amount owing by each such non-resident Holder to the Corporation, and shall give notice to each such non-resident Holder of the amount owing by such non-resident Holder to the Corporation each time there is change in the amount owing arising other than from the accrual of interest. The Trustee may withhold any such amount owing by a non-resident Holder from any concurrent or subsequent payment that would, were it not for such withholding, have been actually made to such non-resident Holder and shall pay such amounts withheld to the Corporation who shall apply such amounts so received by the Corporation to reimburse the Corporation for amounts paid or deemed to have been paid by it pursuant to this section 2.12 and interest thereon as provided in this section 2.12.

-14-

(e) Any amount withheld by the Trustee or the Corporation on account of Withholding Tax, including all such amounts paid or deemed to be paid on behalf of a non-resident Holder by the Corporation pursuant to this section 2.12, shall be remitted by the Trustee or the Corporation to the appropriate government authorities within the time required by law and evidence thereof shall be delivered to the Corporation forthwith thereafter.

(f) The obligation of a non-resident Holder to pay to the Corporation all amounts owing pursuant to subsection 2.12(d) shall survive the sale or transfer of any or all of the non-resident Holder’s Notes to any other party. The obligation of a non-resident Holder to pay the Corporation all amounts owing under subsection 2.12(d) is a personal obligation of the non-resident Holder and shall not be assumed by or deemed to be assumed by any subsequent transferee of the Notes held by such non-resident Holder. The Trustee shall in no way be liable for any amounts becoming payable to the Corporation pursuant to Section 2.12(d).

(g) The Trustee shall be entitled to withhold delivery of certificates in respect of Notes and Common Shares to which a transferee of Notes may be entitled, until all amounts owing pursuant to subsection 2.12(d) have been paid. Notwithstanding the foregoing, failure to withhold such delivery shall not in any way result in the Trustee becoming liable for such amount.

2.13 Mutilation, Loss, Theft or Destruction

In case any of the Notes issued thereunder shall be mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue, and thereupon the Trustee shall certify, a new Note upon surrender and cancellation of the mutilated Note, or in the case of a lost, stolen or destroyed Note, in lieu of and in substitution for the same, and the substituted Note shall be in a form approved by the Trustee and shall be entitled to the benefits of this Note Indenture equally with all other Notes issued or to be issued thereunder without preference or priority one over another. In case of loss, theft or destruction, the applicant for a substituted Note shall furnish to the Corporation and 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 and surety bond satisfactory to them in their discretion. The applicant shall pay all charges and expenses incidental to the issuance of any substituted Note, including charges and expenses of the Corporation and the Trustee.

2.14 Exchanges of Notes

(a) Notes of any denomination may be exchanged for Notes of any other authorized denomination or denominations, any such exchange to be for Notes of an equivalent aggregate principal amount. Any exchange of Notes may be made at the offices of the Trustee or at the offices of any registrar where registers are maintained for the Notes pursuant to the provisions of section 2.10. Any Notes tendered for exchange shall be surrendered to the Trustee or appropriate registrar and shall be cancelled.

(b) Upon the occurrence of an Exchange Tax Event the Corporation may, subject to and in accordance with the provisions of Article 9, call a special meeting of Holders to consider an exchange of any series of Notes for a new series of Notes, having such terms and conditions as approved by a simple majority of Holders.

(c) Except as herein otherwise provided, upon any exchange of Notes of any denomination for other Notes and upon any transfer of Notes, the Trustee or other registrar may make a sufficient charge to reimburse it for any stamp or security transfer taxes or other governmental charge required to be paid and, in addition, a reasonable charge for its services and payment of the said charge shall be made by the party requesting such exchange or transfer as a condition precedent thereto.

(d) Notwithstanding the foregoing provisions of this section 2.14, no charge shall be made to a Holder thereunder for any exchange or transfer of any Note applied for within a period of 30 days from the date of this Note Indenture.

-15-

2.15 Transfer

Subject to section 2.10 the Notes may be resold, distributed or transferred by the Holder at any time subject always to any applicable laws and required regulatory approvals, including, without limitation, applicable securities laws which restrict the sale and distribution of the Notes.

2.16 Option of Holder as to Place of Payment

Except as herein otherwise provided, all sums which may at any time become payable, whether at maturity or on a declaration or otherwise, on account of any Note 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 Note are payable.

2.17 Trustee Not Bound to Make Enquiries

The Trustee may nevertheless, in its discretion, require further proof in cases where it receives a Noteholders’ Request or where it deems further proof desirable.

2.18 Creation and Issue of Additional Notes

(a) Subject to subsection (e), the Directors may from time to time authorize the creation of one or more series of Additional Notes hereunder. Additional Notes of any series may be limited to such aggregate principal amount and bear such rate or rates of interest (subject to subsection (b) below), and mature on such date or dates (subject to section 2.19), and contain such other terms or provisions not inconsistent herewith as the Corporation may determine. Notwithstanding any provision contained herein, no Additional Notes of any series shall be created with a maturity period of less than 5 years.

(b) All Additional Notes shall be issued in the minimum denomination of $100.00 and for amounts above such minimum only in integral multiples of $1.00.

(c) Before the issue of any Additional Notes, the Corporation shall execute and deliver to the Trustee an indenture supplemental hereto for the purpose of establishing the terms thereof and the forms and denominations in which they may be issued, together with a certified resolution of the directors of the Corporation authorizing the same, and the Trustee shall execute and deliver such supplemental indenture pursuant to Article 12.

(d) When a new series of Additional Notes shall have been authorized as aforesaid the same may from time to time be executed by the Corporation and delivered to the Trustee and, subject to subsection (e) below and section 2.1, shall be certified by or on behalf of the Trustee and delivered by it to or upon the Written Direction of the Corporation upon receipt by the Trustee of the following:

(i) a Certified Resolution of the Directors of the Corporation authorizing certification and delivery of a specified principal amount of such series of Notes;

(ii) a written request of the Corporation for the certification and delivery of such Notes; and

(iii) such other documents as the Trustee may reasonably request.

(e) No Additional Notes shall be certified or delivered hereunder if, to the knowledge of the Trustee, an Event of Default shall have occurred and be continuing and shall not have been waived in accordance with section 6.10.

-16-

2.19 Extension of Maturity Date

In the event that any Additional Notes created pursuant to section 2.18 mature on a date later than the then existing Maturity Date, the Maturity Date for all outstanding Notes shall be extended to such later date; provided that in no event shall the Maturity Date be so extended past November 25, 2033.

4.5 Failure to Surrender Notes Called for Redemption

In case the Holder of any Note shall fail, within 30 days after the date fixed for redemption, to surrender his Notes, or shall not within such time accept payment of the other redemption moneys payable in respect thereof and give such receipt therefor, if any, as the Trustee may require, such redemption moneys shall be set aside in trust for such Holder, at such rate of interest as the depositary may allow, either in the deposit department of the Trustee or in a separate account maintained at the principal bankers for the Corporation and such setting aside shall for all purposes be deemed a payment to the Holder of the Note so set aside, and to that extent said Notes shall thereafter not be considered as outstanding hereunder and the Holder of the Note shall have no other right except to receive payment out of the moneys so paid and deposited upon surrender and delivery up of his Notes, of the redemption price of such Notes plus such interest thereon, if any, as the depositary may allow.

4.6 Cancellation of Notes

All Notes purchased or redeemed by the Corporation under the provisions of this Article 4 shall be forthwith delivered to and cancelled by the Trustee and no Notes shall be issued in substitution therefor.

4.7 Surrender of Notes for Cancellation

If the principal moneys due upon any Notes issued hereunder shall become payable by redemption or otherwise before the Maturity Date, the person presenting such Notes for payment must surrender the same for cancellation, the Corporation nevertheless paying the interest accrued and unpaid thereon if the date fixed for payment is not an Interest Payment Date. All Notes and coupons which shall have been delivered to and cancelled by the Trustee shall be destroyed by the Trustee and, if required by the Corporation, the Trustee shall furnish to it a destruction certificate setting forth the numbers and denominations of the Notes and coupons so destroyed.

ARTICLE 5
SUBORDINATION OF THE NOTES

5.1 Agreement to Subordinate

(a) The Corporation covenants and agrees, and each Holder of a Note, by his acceptance thereof, likewise agrees, that (i) the payment of the principal of and interest on the Notes and all other amounts payable pursuant to this Note Indenture shall be junior, subject and subordinate, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness, and (ii) that any and all Liens now or hereinafter held by the Trustee or the Holders as security for the payment and performance of all obligations, indebtedness and liabilities of the Corporation under the Notes shall be junior, subject and subordinate in all respects to any and all Liens now or hereafter held by the holders of Senior Indebtedness as security for the payment and performance of all obligations, indebtedness and liabilities of the Corporation under the Senior Indebtedness or any part thereof.

(b) Nothing contained in this Article 5 is intended to or shall restrict the Corporation from incurring additional indebtedness or from mortgaging, pledging or otherwise charging its undertaking, property or assets to secure any indebtedness or liability.

5.2 Distribution on Insolvency or Winding-Up

(a) Upon any dissolution, winding-up, liquidation, reorganization or other similar proceedings relative to the Corporation or its property or assets, resulting from bankruptcy, insolvency, involuntary reorganization or receivership proceedings or upon an assignment for the benefit of creditors or other marshalling of the assets and liabilities of the Corporation for the benefit of creditors:

(i) the holders of all Senior Indebtedness will first be entitled to receive payment in full of the principal thereof, premium, if any, interest due thereon, and all other amounts payable in respect of Senior Indebtedness before the Holders are entitled to receive any payment on account of the principal of, premium, if any, or interest on, the Notes;

(ii) any payment by, or distribution of assets of, the Corporation of any kind or character, whether in cash, property or securities (other than securities of the Corporation or any other corporation provided for by a plan of reorganization or arrangement the payment of which is subordinate, at least to the extent provided in this Article 5 with respect to the Notes, to the payment of all Senior Indebtedness, provided that (1) all Senior Indebtedness is assumed by the new corporation, if any, resulting from such reorganization or arrangement and (2) the rights of the holders of Senior Indebtedness are not altered adversely by such reorganization or arrangement (“Excluded Securities”)), to which the Holders or the Trustee would be entitled except for the provisions of this Article 5, will be paid or delivered by the person making such payment or distribution, whether a trustee in bankruptcy, a receiver, a receiver-manager, an assignee for benefit of creditors, a liquidator or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the Senior Indebtedness held or represented by each such holder to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid after giving effect to any concurrent payment or distribution (or provision therefor) to the holders of such Senior Indebtedness;

(iii) subject to section 5.6, if, notwithstanding the foregoing, any payment by, or distribution of assets of, the Corporation of any kind or character, whether in cash, property or securities (other than Excluded Securities), which is provided in subsections (i) or (ii) above to be paid to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, is received by the Trustee or the Holders before all Senior Indebtedness is paid in full, such payment or distribution, unless received by the

-20-

Trustee or the Holders prior to the commencement of an event resulting in a payment or distribution as contemplated in this section 5.2 and held by the Trustee under this Note Indenture, will be held in trust for the benefit of, and will be paid over to the holders of such Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably as aforesaid, for application to the payment of all Senior Indebtedness remaining unpaid until such Senior Indebtedness has been paid in full, after giving effect to any concurrent payment or distribution (or provision therefor) to the holders of such Senior Indebtedness;

(iv) each Holder of one or more Notes, by his acceptance thereof, authorizes the Trustee to take such steps as may be necessary or appropriate to entitle the holder or holders of Senior Indebtedness to receive payment or distribution from the trustee in bankruptcy, receiver, receiver-manager, assignee for benefit of creditors, or other liquidating agent making such payment or distribution, all to the extent necessary to provide for payment of all Senior Indebtedness in full, in money or money’s worth, in priority to any payment of the indebtedness represented by the Notes as hereinabove provided; and

(v) whenever all Senior indebtedness shall have been paid in full, in money or money’s worth, the Holders of Notes shall be entitled to receive payment or distribution from the trustee in bankruptcy, receiver, receiver-manager, assignee for the benefit of the creditors, or other liquidating agent making such payment or distribution, of the assets available for purposes of such payment or distribution.

(b) In the event of any payment or distribution of assets of the Corporation referred to in this Article 5, the Trustee and the Holders of the Notes shall be entitled to rely upon a certificate of the trustee in bankruptcy, receiver, receiver-manager, assignee for benefit of creditors or the liquidating agent making such payment or distribution, delivered to the Trustee or to the Holders of Notes, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of Senior Indebtedness and other indebtedness of the Corporation, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 5. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and neither the Trustee nor any Holders of Notes shall be liable to any such holder of Senior Indebtedness if the Trustee shall mistakenly pay over or distribute to Holders of Notes or the Corporation or any other person, moneys or assets to which any holders of Senior Indebtedness shall be entitled by virtue of Article 5 of this Note Indenture or otherwise.

5.3 Subrogation of Notes

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

-21-

5.4 No Payment to Holders if Event of Default under Senior Indebtedness

(a) Nothing contained in this Article 5 or elsewhere in this Note Indenture shall affect the obligation of the Corporation to make, or prevent the Corporation from making, any payment of principal of or interest on the Notes, except that, other than as contemplated by section 5.2, the Corporation shall not, until all payments to holders of Senior Indebtedness contemplated pursuant to subsection (i) below have been made (but may do so thereafter, or if no payment is required thereunder), make any such payment:

(i) at any time during the pendency of any dissolution, winding-up, liquidation, reorganization or other similar proceedings relating to the Corporation or its property or assets as specified in section 5.2; or

(ii) if such payment would be prohibited under subsection (b) below.

The fact that any such payment is prohibited by this section 5.4 shall not prevent the failure to make such payment from being an Event of Default hereunder.

(b) Except as hereinafter otherwise provided in subsections (c) and (d) below and in sections 5.2 and 5.6, the Corporation shall not make any payment on the Notes or, if directed in writing by the holders, (including, for this purpose, the trustee or trustees for the holders) of at least 50% of the aggregate principal amount of Designated Senior Indebtedness outstanding at the time of such approval, (such holders herein called “Approving Holders”) on any other indebtedness or liabilities of the Corporation other than Designated Senior Indebtedness and other than such indebtedness and liabilities, if any, approved by the Approving Holders, and the Trustee shall not be entitled to receive, retain or make any payments on account or of the indebtedness represented by the Notes or to demand, institute proceedings for the collection of, or receive any payment or benefit (including without limitation by compensation, set-off, combination of accounts or realization of security or otherwise in any manner whatsoever) on account of indebtedness represented by the Notes (i) in a manner inconsistent with the terms (as they exist on the date hereof) of this Note Indenture, or (ii) at any time when an event of default, as defined in any Senior Indebtedness or any instrument evidencing the same and permitting the holders thereof to accelerate the maturity thereof, has occurred and is continuing, or an event which, with the giving of notice or passage of time would constitute such an event of default has occurred and is continuing, and notice has been given in accordance with the terms of such Senior Indebtedness or instrument in respect of such event of default by or on behalf of the holders of Senior Indebtedness to the Corporation and the Trustee, in each case unless and until such Senior Indebtedness has been paid and satisfied in full or unless and until such event of default shall have been cured or waived or shall have ceased to exist.

(c) Nothing contained in this Article 5 or elsewhere in this Note Indenture or in any of the Notes shall be construed so as to prevent the Trustee from receiving, retaining and making any payments on account of Notes which are made (i) in a manner that is consistent with the terms of this Note Indenture and (ii) at any time when no event of default, as defined in any Senior Indebtedness or the instrument creating the same and permitting the holders thereof to accelerate the maturity thereof, or an event which, with the giving of notice or passage of time would constitute such an event of default has occurred and is continuing, in respect of which notice has been given by or on behalf of the holders of Senior Indebtedness to the Corporation and the Trustee.

(d) Nothing contained in this Article 5 or elsewhere in this Note Indenture or in any of the Notes shall be construed so as to prevent the payment or distribution of: (i) any securities distributable to the Holders under a Share Payment Election; or (ii) Excluded Securities to the Holders.

5.5 Authorization of Holders to Trustee to Effect Subordination

Each Holder of a Note, by his acceptance thereof, authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effect the subordination provided for in this Article 5 and appoints the Trustee his attorney-in-fact for any and all such purposes.

-22-

5.6 Knowledge of Trustee

Notwithstanding the provisions of this Article 5 or any provisions of this Note Indenture or of the Notes, the Trustee shall not be charged with knowledge of the existence of any Senior Indebtedness or of the terms of any default in the payment thereof or occurrence of an event of default in respect thereof or of the terms of any instrument evidencing Senior Indebtedness, and the Trustee shall be entitled to assume that no such event of default has occurred or that no such facts exist, unless and until the Trustee shall have received written notice thereof from the Corporation or shall have received notice in the manner prescribed by the terms of such Senior Indebtedness or instrument for declaring any such event of default and giving notice thereof, from a trustee or other authorized representative of, or the specified number or percentage of, the holders of any such Senior Indebtedness, and, with respect to any money which may at any time be received by the Trustee in trust pursuant to any provision of this Note Indenture, unless and until such written notice has been received, nothing in this Note Indenture shall prevent the Trustee from applying such money to the purposes for which the same was so received, notwithstanding the occurrence or continuance of such default or the existence of such facts with respect to such Senior Indebtedness.

5.7 Trustee May Hold Senior Indebtedness

The Trustee is entitled to all the rights set forth in this Article 5 with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Note Indenture deprives the Trustee of any of its rights as such holder.

5.8 Rights of Holders of Senior Indebtedness Not Impaired

No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein will at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Corporation or by any non-compliance by the Corporation with the terms, provisions and covenants of this Note Indenture, regardless of any knowledge thereof any such holder may have or otherwise be charged with.

5.9 Altering the Senior Indebtedness

The holders of Senior Indebtedness have the right to extend, renew, modify or amend the terms of the Senior Indebtedness or any security thereof and to release, sell or exchange such security and otherwise to deal freely with the Corporation, all without notice to or consent of the Holders and without affecting the liabilities and obligations of the parties to this Note Indenture or the Holders.

ARTICLE 6
DEFAULT

6.1 Events of Default

It shall be an Event of Default if:

(a) the Corporation makes default in repayment, in cash or pursuant to a Share Payment Election, of the principal amount of the Notes, any series of Notes or any Note when due, whether on the Maturity Date, upon redemption, by acceleration on default or otherwise; provided that a valid extension by the Corporation of the Maturity Date in accordance with section 2.19 of this Note Indenture shall not constitute a default in the repayment of principal;

(b) the Corporation makes default in payment, in cash or pursuant to a Share Payment Election; of any interest on the Notes, any series of Notes, or any Note when such interest becomes due and payable, and such default continues for a period of 30 days; provided that a deferral of the Interest Payment Date for such Notes in accordance with section 2.4 of this Note Indenture shall not constitute a default in the payment of interest for this purpose unless such failure to pay interest continues beyond the end of the Deferral Period in respect thereof, as last extended;

(c) an event of default, as defined in any indenture or instrument under which the Corporation or any material Subsidiary of the Corporation has at the formal date of this Note Indenture, or shall hereafter have, outstanding, in the case of the Corporation, any Senior Indebtedness or, in the case of any

-23-

material Subsidiary of the Corporation (and for the purposes of this section 6.1, “material Subsidiary” shall mean a Subsidiary which accounts for 20% of the gross assets or gross income of the Corporation on a consolidated basis), any indebtedness, shall happen and be continuing and such Senior Indebtedness or material Subsidiary’s indebtedness, as the case may be, shall have been accelerated so that an amount in excess of $10,000,000 shall be or become due and payable prior to the date on which the same would otherwise have become due and payable;

(d) the Corporation shall fail to observe or perform any covenant or condition of the Corporation in this Note Indenture (other than a covenant or condition which is specifically dealt with elsewhere in this section 6.1), and such failure to observe or perform continues for a period of 60 days after there has been given, by registered or certified mail, to the Corporation by the Trustee or to the Corporation and the Trustee by the Holders of at least 25% in aggregate principal amount of all outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;

(e) a decree or order of a court having jurisdiction in the premises is entered adjudging the Corporation or any material Subsidiary a bankrupt or insolvent under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws, or issuing sequestration or process of execution against, or against any substantial part of the property of, the Corporation or any material Subsidiary, or appointing a receiver of, or of any substantial part of the property of, the Corporation or any material Subsidiary, or ordering the winding-up or liquidation of its affairs, and any such decree or order is not forthwith contested and has not been vacated, discharged or stayed within and otherwise remains in effect for a period of 30 days;

(f) a resolution is passed for the winding-up or liquidation of the Corporation or any material Subsidiary (other than a wholly-owned subsidiary) or if the Corporation or any material Subsidiary institutes proceedings to be adjudicated a bankrupt or insolvent, or consents to the institution of bankruptcy or insolvency proceedings against it under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous laws, or consents to the filing of any such petition or to the appointment of a receiver of, or of any substantial part of, the property of the Corporation or any material Subsidiary or makes a general assignment for the benefit of creditors, or admits in writing its inability to pay its debts generally as they become due;

(g) the Corporation shall neglect to observe or perform any other covenant or condition herein contained on its part to be observed or performed and, after notice in writing has been given by the Trustee to the Corporation specifying such default and requiring the Corporation to put an end to the same (which said notice may be given by the Trustee, in its discretion, and shall be given by the Trustee upon receipt of a Noteholder’s Request) the Corporation shall fail to make good such default within a period of thirty (30) days, unless the Trustee (having regard to the subject matter of the default) shall have agreed to a longer period, and in such event, within the period agreed to by the Trustee;

(h) any proceedings with respect to the Corporation or any material Subsidiary are taken after the date of this Note Indenture with respect to a compromise or arrangement under the Companies Creditors Arrangement Act (Canada) (or any Act substituted therefor) or similar legislation of any other jurisdiction;

(i) any encumbrancer takes possession of, in the opinion of the Trustee (based upon an opinion of Counsel), all or substantially all of the property of the Corporation or of any material Subsidiary, or if a distress or execution or any similar process is enforced against such property and remains unsatisfied for so long as would permit any part of such property to be sold thereunder, or if a custodian or sequestrator or a receiver or receiver and manager or any other officer with similar powers is appointed for the Corporation or for any material Subsidiary, or for all or substantially all or the property of the Corporation or of any material Subsidiary, and the Corporation or such material Subsidiary shall have failed to pay the amount owing and satisfy the claim under and discharge or terminate any such encumbrance, distress, execution or other process or appointment within 30 days; or

-24-

(j) the Corporation or any material Subsidiary shall cease to carry on, in the ordinary course, its business or a substantial part thereof.

6.2 Acceleration of Maturity, Rescission and Annulment

(a) If an Event of Default with respect to the Notes has occurred and is continuing, the Trustee may or, on the instructions of the Holders of not less than 25% in aggregate principal amount of the outstanding Notes shall, declare the Maturity Amount of such Notes and any other amounts payable under this Note Indenture to be forthwith due and payable immediately and the Trustee may enforce the rights of the Holders of such Notes as creditors, by a notice in writing to the Corporation. Upon any such declaration, without limiting the rights of the Corporation under section 2.6, the principal, accrued and unpaid interest and all other monies outstanding under such Notes shall become immediately due and payable notwithstanding anything contained in this Note Indenture or in such Notes to the contrary, and the Corporation shall forthwith pay to the Trustee for the benefit of the Holders such principal, accrued and unpaid interest and all other monies outstanding thereunder, together with interest at the Interest Rate on such amounts from the date of such declaration until payment is received by the Trustee. Such payment when made shall be deemed to have been made in discharge of the Corporation’s obligations under such Notes and any monies so received shall be applied in the manner provided in section 6.13.

(b) At any time after a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as provided in this Article 6, the Holders of not less than a majority in aggregate principal amount of the outstanding Notes, by written notice to the Corporation and the Trustee, may rescind and annul such declaration and its consequences; provided that:

(i) the Corporation shall have paid or deposited with the Trustee a sum sufficient to pay:

A. all overdue interest (including accrued interest, if any) on all outstanding Notes;

B. all unpaid principal of any outstanding Notes which has become due otherwise than by such declaration of acceleration, and interest on such unpaid principal at the applicable Interest Rate;

C. to the extent lawful, interest on overdue interest at the rate or rates prescribed therefor in such Notes;

D. all sums paid or advanced by the Trustee under this Note Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;

E. any other amounts payable under this Note Indenture; and

(ii) all Events of Default with respect to the Notes, other than the default in the payment of amounts of principal of or interest on the Notes which have become due solely by such declaration of acceleration, shall have been cured or waived as provided in section 6.10.

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

(c) In the event that the Trustee shall have proceeded to enforce any right with respect to the Notes 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 Trustee, then and in every such case, the Corporation and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Corporation and the Trustee shall continue as though no such declaration or proceedings had been made or taken.

-25-

6.3 Control by Holders

Subject to sections 6.4, and 11.10, the Holders shall have the right, exercisable by Noteholders’ Request, to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, relating to or arising upon an Event of Default with respect to the Notes; provided that:

(a) such direction shall not be in conflict with any rule of law or with this Note Indenture;

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

(c) the Trustee need not take any action required by such direction which might involve the Trustee in personal liability,

6.4 Remedies Blockage Period

The Trustee will, at the Written Direction of the Corporation from time to time, enter into an agreement with the holders of Designated Senior Indebtedness or a trustee or authorized representative for the holders of Designated Senior Indebtedness, agreeing with such holders or such trustee or authorized representative not to accelerate or commence or take any action, suit or other proceeding to enforce the rights of the Holders of the Notes during the period of 36 consecutive months following an Event of Default in the event that such Designated Senior Indebtedness is outstanding during such period (the “Remedies Blockage Period”). The Corporation will not provide such Written Direction of the Corporation unless it has been requested to do so by a holder of Designated Senior Indebtedness (or person that becomes a holder of Designated Senior Indebtedness) or, by a representative of such holder or such person, but the Trustee shall be entitled to act and rely upon such Written Direction of the Corporation and shall not be required by any such holder or person or representative to inquire into whether the Corporation has been requested to give such Written Direction of the Corporation.

6.5 Remedies Not Exclusive

No remedy for the enforcement of rights of the Holders under this Article 6 shall be exclusive of or dependent on any other such remedy, but any one or more of such remedies may from time to time be exercised independently or in combination.

6.6 Costs

The Corporation shall be liable to the Trustee for all costs incurred by the Trustee in connection with the enforcement of rights under this Note Indenture together with interest thereon at the Interest Rate from the date such costs are incurred until the date payment thereof is received by the Trustee.

6.7 Delay

No delay or omission of the Trustee or any Holder to exercise any remedy shall impair any such remedy or shall be construed to be a waiver of default hereunder or acquiescence herein.

6.8 No Recourse Against Other Parties

Neither the Trustee nor the Holders shall have any right, cause of action or remedy now or hereafter existing in any jurisdiction against any past, present or future incorporator, shareholder, director or officer of the Corporation for the payment of the principal or interest under any or all of the Notes or on any covenants, agreement, representation or warranty of the Corporation contained herein or in the Notes.

6.9 Notice of Events of Default

If an Event of Default shall occur and be continuing, the Trustee shall, within 30 days after it becomes aware of the occurrence of such Event of Default, give notice of such Event of Default to the Holders in the manner provided in section 10.1; provided that, notwithstanding the foregoing, unless the Trustee shall have been requested to do so by a Noteholders’ Request, the Trustee shall not be required to give such notice if the Trustee in good faith shall have

-26-

determined that the withholding of such notice is in the best interests of the Holders and shall have so advised the Corporation in writing.

6.10 Waiver of Default

Subject to the satisfaction of section 6.2(b)(i) and subject to subsection 9.11(e), the Holders may waive any past Default and its consequences, except a Default in respect of the payment when due of principal or interest (unless such Event of Default has been cured and a sum sufficient to pay all matured instalments of interest and principal due otherwise than by acceleration has been deposited with the Trustee). Upon any such waiver, any such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Note Indenture; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

6.11 Enforcement by the Trustee

(a) Subject to the provisions of section 6.9 and to the provisions of any Extraordinary Resolution that may be passed by the Holders, in case the Corporation shall fail to pay to the Trustee, forthwith after the same shall have been declared to be due and payable under section 6.2, the principal and interest on all Notes outstanding, together with any other amounts due hereunder, the Trustee may, upon being indemnified and funded to its reasonable satisfaction against all costs, expenses and liabilities to be incurred, proceed in its name as Trustee hereunder to obtain or enforce payment of the said principal and interest on all the Notes then outstanding together with any other amounts due thereunder by such proceedings authorized by this Note Indenture or by law or equity as the Trustee shall have been directed by the Holders by Extraordinary Resolution to take, or if such Extraordinary Resolution contains no such direction, or if the Trustee shall act without such Extraordinary Resolution, then by such proceedings authorized by this Note Indenture or by suit at law or in equity as the Trustee shall deem expedient.

(b) Notwithstanding sections 6.2 and 6.3, the Trustee shall be entitled and empowered, either in its own name or as trustee of an express trust, or as attorney-in-fact for the Holders, or in any one or more of such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claims of the Trustee and of the Holders allowed in any insolvency, bankruptcy, liquidation or other judicial proceedings relative to the Corporation or its creditors or relative to or affecting its property. The Trustee is hereby irrevocably appointed (and the successive respective Holders by taking and holding the Notes shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective Holders with authority to make and file in the respective names of the Holders or on behalf of the Holders as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the Holders themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sum becoming distributable on account thereof, and to execute any such acts and things for and on behalf of such Holders, as may be necessary or advisable in the opinion of the Trustee, (based upon an opinion of Counsel) in order to have the respective claims of the Trustee and of the Holders against the Corporation or its property allowed in any such proceeding, and to receive payment of or on account of such claims, provided, however, that nothing contained in this Note Indenture shall be deemed to give to the Trustee, unless so authorized by Extraordinary Resolution, any right to accept or consent to any plan or reorganization or otherwise by action of any character in such proceeding waive or change in any way any right of any Holder.

(c) Notwithstanding sections 6.2 and 6.3, the Trustee shall also have power at any time and from time to time to institute and to maintain such suits and proceedings as it may be advised shall be necessary or advisable to preserve and protect its interests and the interests of the Holders.

(d) All rights of action hereunder may be enforced by the Trustee without the possession of any of the Notes or the production thereof on the trial or other proceedings relative thereto. Any such suit or proceeding instituted by the Trustee shall be brought in the name of the Trustee as trustee of an express trust, and any recovery of judgment shall be for the ratable benefit of the Holders subject to the provisions of this Note Indenture. In any proceeding brought by the Trustee (and also any

-27-

proceeding in which a declaratory judgment of a court may be sought as to the interpretation or construction of any provision of this Note Indenture, to which the Trustee shall be a party) the Trustee shall be held to represent all of the Holders, and it shall not be necessary to make any Holders party to any such proceeding.

6.12 No Suits by Holders

No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Note Indenture, for the appointment of a receiver or trustee, or for any other remedy under this Note Indenture, unless:

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to such Notes;

(b) the Holders of not less than 25% in aggregate principal amount of outstanding Notes, in the case of an Event of Default, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Note Indenture and shall have offered to the Trustee reasonable indemnification against the costs, expenses and liabilities to be incurred by the Trustee in compliance with such request;

(c) the Trustee has, for 60 days after its receipt of such notice, request and offer of indemnification, failed to institute any such proceeding;

(d) no direction inconsistent with such written request has been given to the Trustee during such 60 day period by the Holders of a majority or more in aggregate principal amount of the outstanding Notes in the case of an Event of Default;

(e) the bringing of such action, suit or proceeding would not be contrary to Article 6; and

(f) the Remedies Blockage Period has expired,

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Note Indenture to affect, disturb or prejudice the rights of any other Holders, in the case of an Event of Default to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Note Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders. For the protection and enforcement of the provisions of this section 6.12, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

6.13 Application of Monies by Trustee

Except as herein otherwise expressly provided, any money received by the Trustee from the Corporation pursuant to the foregoing provisions of this Article 6, or as a result of legal or other proceedings or from any trustee in bankruptcy or liquidator of the Corporation, shall be applied, together with any other monies in the hands of the Trustee available for such purpose as follows:

(a) first, in payment or in reimbursement of the Trustee of its compensation, costs, charges, expenses, borrowings, advances or other monies furnished or provided by or at the instance of the Trustee in or about the execution of its trusts under, or otherwise in relation to this Note Indenture, with interest thereon as herein provided;

(b) second, but subject as hereinafter in this section 6.13 provided, in payment, ratably and proportionately to the Holders, of the principal of and accrued and unpaid interest and interest on amounts in default on the Notes which shall then be outstanding, in the priority of accrued and unpaid interest and interest on amounts in default first and then principal, unless otherwise directed by Extraordinary Resolution and in that case in such order or priority as between principal and interest as may be directed by such resolution; and

(c) third, in payment of the surplus, if any, of such monies to the Corporation or its assigns;

-28-

provided, however, that no payment shall be made pursuant to clause (b) above with respect to the principal or interest of any Note held, directly or indirectly, by or for the benefit of the Corporation or any Subsidiary (other than any Note pledged for value and in good faith to a person other than the Corporation or any Subsidiary, but only to the extent of such person’s interest therein) except subject to the prior payment in full of the principal and interest of all Notes which are not so held.

6.14 Distribution of Proceeds

Payments to the Holders pursuant to section 6.13(b) shall be made as follows:

(a) at least 15 days notice of every such payment shall be given in the manner provided in section 10.1 specifying the time when and the place or places where the Notes are to be presented and the amount of the payment and the application thereof as between principal and interest;

(b) payment of any Note shall be made upon presentation thereof at any one of the places specified in such notice and any such Note thereby paid in full shall be surrendered, otherwise a memorandum of such payment shall be endorsed thereon; but the Trustee may in its discretion dispense with presentation and surrender or endorsement in any special case upon such indemnity being given as it shall deem sufficient;

(c) from and after the date of payment specified in the notice, interest shall accrue only on the amount owing on each Note after giving credit for the amount of the payment specified in such notice unless the Note with respect to which such amount is owing is duly presented on or after the date so specified and payment of such amount is not made; and

(d) the Trustee shall not be bound to apply or make any partial or interim payment of any monies coming into its hands if the amount so received by it, after reserving thereon such amount as the Trustee may think necessary to provide for the payments mentioned in section 6.13(a), is insufficient to make a distribution of at least two percent (2%) of the aggregate principal amount of the outstanding Notes, but it may retain the money so received by it and invest or deposit the same as provided in section 11.9 until the money or the investments representing the same, with the income derived therefrom, together with any other monies for the time being under its control shall be sufficient for the said purpose or until it shall consider it advisable to apply the same in the manner hereinbefore set forth. The foregoing shall, however, not apply to a final payment or distribution hereunder.

The Corporation covenants and agrees with the Trustee that, in case of any judicial or other proceedings to enforce the rights of the Holders, judgment may be rendered against it in favour of the Holders or in favour of the Trustee, as trustee for the Holders, for any amount which may be proved to remain due with respect to the Notes and the interest thereon and any other monies owing hereunder.

7.3 Repayment of Unclaimed Monies

Any monies set aside under section 7.2 and not claimed by and paid or delivered to Holders as provided in section 7.2 within six years after the date of such setting aside shall, subject to applicable laws, be repaid or returned to the Corporation by the Trustee and thereupon the Trustee shall be released from all further liability with respect to such monies and thereafter the Holders with respect to which such monies were so repaid to the Corporation shall have no rights with respect thereto except to obtain payment or delivery of the monies due thereon from the Corporation up to such time as the right to proceed against the Corporation for recovery of such monies has become statute-barred under the laws of the Province of Alberta, after which time the monies will become the property of the Corporation.

7.4 Discharge

The Trustee shall at the request of the Corporation release and discharge this Note Indenture and execute and deliver such instruments as it shall be advised by Counsel are requisite for that purpose and to release the Corporation from its covenants herein contained (other than the provisions relating to the indemnification of the Trustee) upon proof being given to the reasonable satisfaction of the Trustee that the principal of and interest (including interest on amounts in default, if any), on all the Notes and all other monies or other consideration payable hereunder have been paid or satisfied or that, all the Notes having matured, payment of the principal of and interest (including interest on amounts in default, if any) on such Notes and on all other monies or other consideration payable hereunder has been duly and effectually provided for in accordance with the provisions hereof.

The accidental omission to give notice of a meeting to any Holder shall not invalidate any resolution passed at any such meeting.

9.3 Chairman

A person, who need not be a Holder, nominated in writing by the Trustee, shall be chairman of the meeting and if no person is so nominated, or if the person so nominated is not present within 15 minutes from the time fixed for the holding of the meeting, the Holders present in person or by proxy shall choose a person present at the meeting to be chairman.

The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote with respect to the Notes, if any, held by him.

9.7 Poll

On every Extraordinary Resolution, and on any other question submitted to a meeting, when demanded by the chairman or by one or more Holders or proxies for Holders, a poll shall be taken in such manner and either at once or after an adjournment as the chairman shall direct.

ARTICLE 11
CONCERNING THE TRUSTEE

11.1 No Conflict of Interest

The Trustee represents to the Corporation that at the date of execution and delivery by it of this Note Indenture there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder, but if, notwithstanding the provisions of this section 11.1, such a material conflict of interest exists, the validity and enforceability of this Note Indenture, and the Notes issued hereunder shall not be affected in any manner whatsoever by reason only that such material conflict of interest exists but the Trustee shall, within 90 days after ascertaining that it has a material conflict of interest, either eliminate such material conflict of interest or resign in the manner and with the effect specified in section 11.2. However, the Corporation hereby acknowledges that a material conflict of interest in the role of the Trustee as a fiduciary hereunder may arise in connection with the Trustee’s role as a fiduciary under the Trust Indenture and as the holder of the Notes as contemplated under the Arrangement. In such circumstances, the Corporation confirms that if the Trustee, acting reasonably, determines that such a material conflict of interest exists that prevents the Trustee from fulfilling its obligations hereunder or that such a conflict of interest is imminent, the Trustee shall be entitled to resign in the manner and with the effect specified in Section 11.2 provided that at no time shall the Trustee be required to take any action which would conflict with its obligations as a fiduciary under the Trust Indenture.

11.2 Replacement of Trustee

(a) The Trustee may resign its trust and be discharged from all further duties and liabilities hereunder by giving to the Corporation two months notice in writing or such shorter notice as the Corporation may accept as sufficient. In the event of the Trustee resigning or being removed or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Trustee unless a new Trustee has already been appointed by the Holders; failing such appointment by the Corporation, the retiring Trustee or any Holder may apply to a Justice of the Court of Queen’s Bench of Alberta, on such notice as such Justice may direct, for the appointment of a new Trustee; but any new Trustee so appointed by the Corporation or by the Court, shall be subject to removal as herein provided by the Holders. Any new Trustee appointed under any provision of this section 11.2 shall be a corporation authorized to carry on the business of a

-37-

trust company in the Province of Alberta. On any new appointment, the new Trustee shall be vested with the same powers, rights, duties and responsibilities as if it bad been originally named herein as Trustee.

(b) Any corporation into which the Trustee may be merged or with which it may be consolidated or amalgamated or any corporation resulting from any merger, consolidation or amalgamation to which the Trustee shall be a party, shall be the successor Trustee under this Note Indenture without the execution of any instrument or any further act. Nevertheless, upon the written request of the successor Trustee or of the Corporation, the Trustee ceasing to act shall execute and deliver an instrument assigning and transferring to such successor Trustee, upon the trusts herein expressed, all the rights, powers and trusts of the Trustee so ceasing to act, and shall duly assign, transfer and deliver all property and money held by such Trustee to the successor Trustee so appointed in its place.

DUE NOVEMBER 25, 2024

Enterra Acquisition Corp.

Interest is payable on the 15th day of each month (each an “Interest Payment Date”) during the term hereof commencing the 15th day of January, 2004 in respect of interest accrued to the first day of each such month (each an “Interest Accrual Date”) immediately preceding such Interest Payment Date, subject to deferral in accordance with the provisions of the Note Indenture.

As interest becomes due on this Note (except at maturity, when interest may be paid upon the surrender thereof for payment), the Corporation shall cause to be: (i) sent by prepaid ordinary mail a cheque or, (ii) delivered by other transfer of funds by such means as may be considered appropriate by the Trustee, for such interest (less any Canadian Taxes required by law to be withheld or deducted therefrom) payable to the order of the Holder and addressed to it at its last address or account, as the case may be, appearing on the register, at the respective Interest Payment Date unless the Holder otherwise directs.

This Note may only be transferred upon compliance with the conditions prescribed in the Note Indenture on the register of transfers to be kept at the principal office of the Trustee in the City of Calgary, and in such other place or places (if any) and/or by such other registrar or registrars (if any) as the Corporation with the approval of the Trustee and Trustee may designate, by the registered holder hereof or his executors or administrators or other legal representatives, or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee and/or other registrar (if any) and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe, and then, only if such transfer shall have been duly entered on one of the appropriate registers or noted on this Note by a proper registrar.

The Note Indenture contains provisions making binding upon all Holders of Notes outstanding thereunder resolutions passed at meetings of such Holders held in accordance with such provisions and instruments in writing signed by the Holders of a specified percentage of the principal amount of the Notes outstanding.

This Note shall not become obligatory for any purpose until it shall have been certified by the Trustee for the time being under the Note Indenture.

Concurrent with the mailing of such funds to each Holder, the Corporation shall provide evidence of such payment to the Trustee.

	(b)		The Corporation may extend the payment of interest by extending the Interest Payment Date in accordance with section 2.4 and shall be deemed to so defer whenever it fails to pay interest under subsection (a) or (c).

	(i)		to satisfy its obligation to pay any interest, including Deferred Interest on any Interest Payment Date (an “Interest Amount”), by delivering Common Shares; or

	(ii)		to satisfy its obligation to pay the principal amount of the Notes plus accrued and unpaid interest thereon on the Maturity Date (a “Maturity Amount”), by delivering Common Shares.

	(c)		In the case of a Share Payment Election in respect of the payment of an Interest Amount, the Share Election Notice shall include: (i) the aggregate Interest Amount (not exceeding the amount of interest, including Deferred Interest, payable in respect of the Notes on such Interest Payment Date) that is being satisfied through the issuance of Common Shares; (ii) the proportion of such Interest Amount that is being satisfied through the issuance of Common Shares, if any; and (iii) the Share Payment Amount.

	(d)		In the case of a Share Payment Election in respect of the payment of a Maturity Amount: (i) the Share Election Notice shall include the aggregate Maturity Amount (not exceeding the principal amount plus accrued and unpaid interest thereon payable in respect of the Notes on the Maturity Date) that is being satisfied through the issuance of Common Shares; (ii) the Corporation shall deliver such Share Election Notice at least 60 days prior to the Maturity Date; and (iii) the Share Payment Amount.

Notwithstanding anything herein contained, the Corporation shall in no case be required to deliver fractional Common Shares to the Trustee in respect of any Share Election Notice. If any fractional interest in a Common Share would, except for the provision of this subsection C, be deliverable to the Trustee, the Corporation shall deliver to the Trustee the next lowest whole number of Common Shares and nothing in this subsection C will be interpreted to entitle the Trustee to any interest, whether legal, beneficial or otherwise, to a number of Common Shares greater than such next lowest number of Common Shares.

	D.		Upon the receipt of the deliveries specified in subsection C above, the Trustee shall consummate such purchase and the Corporation shall issue such Common Shares to the Trustee against payment to the Corporation by the Trustee of the aggregate Share Payment Amount, less any amount attributable to any fractional Common Share, whereupon the sole right of a Holder of a Note in respect of the Interest Amount or the Maturity Amount, as the case may be, will be to the delivery of such Common Shares by the Trustee in full satisfaction of such Interest Amount or Maturity Amount, as the case may be, and the Holder of such Note will have no further recourse against the Corporation or the Trustee in respect of such Interest Amount or Maturity Amount, as the case may be.

	(g)		The Corporation shall indemnify and hold harmless the Trustee and the Holders of Notes, and any person who controls any such Holder within the meaning of any applicable securities laws, from and

Such certification on any Note shall be conclusive evidence that such Note is duly issued, is a valid obligation of the Corporation and is entitled to the benefits hereof.

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

Notice of such transfer shall be given to the Holders of such Notes prior to such transfer.

	(a)		The Person in whose name any Note shall be registered shall be deemed and regarded as the owner thereof for all purposes of this Note Indenture and payment of or on account of the principal of such Note shall be made only to or upon the order in writing of such Holder thereof and such payment shall be good and sufficient discharge to the Trustee and any registrar and to the Corporation and any paying agent for the amounts so paid.

	(b)		The Trustee and the Corporation shall provide the other with all the information in its possession necessary for the Corporation or the Trustee to determine the amount of withholding taxes levied under Part XIII of the Tax Act (Canada) and includes any similar Canadian Taxes hereafter levied in addition to or in substitution therefor, and penalties or interest in respect thereof (“Withholding Taxes”) to be remitted on behalf of each non-resident Holder and to otherwise perform its obligations under this section 2.12.

Any amount paid or deemed to be paid on behalf of a non-resident Holder by the Corporation or the Trustee pursuant to this section 2.12 shall bear interest at the prime rate published from time to time by The Toronto-Dominion Bank (or any successor thereto) (or if at any time a prime rate is not published by such bank, a rate published by a financial institution selected by the Corporation) plus two per cent per annum, calculated daily and compounded monthly from the date of payment or deemed payment. The Trustee shall maintain a separate register showing the amount owing by each such non-resident Holder to the Corporation, and shall give notice to each such non-resident Holder of the amount owing by such non-resident Holder to the Corporation each time there is change in the amount owing arising other than from the accrual of interest. The Trustee may withhold any such amount owing by a non-resident Holder from any concurrent or subsequent payment that would, were it not for such withholding, have been actually made to such non-resident Holder and shall pay such amounts withheld to the Corporation who shall apply such amounts so received by the Corporation to reimburse the Corporation for amounts paid or deemed to have been paid by it pursuant to this section 2.12 and interest thereon as provided in this section 2.12.

	(e)		Any amount withheld by the Trustee or the Corporation on account of Withholding Tax, including all such amounts paid or deemed to be paid on behalf of a non-resident Holder by the Corporation pursuant to this section 2.12, shall be remitted by the Trustee or the Corporation to the appropriate government authorities within the time required by law and evidence thereof shall be delivered to the Corporation forthwith thereafter.

	(f)		The obligation of a non-resident Holder to pay to the Corporation all amounts owing pursuant to subsection 2.12(d) shall survive the sale or transfer of any or all of the non-resident Holder’s Notes to any other party. The obligation of a non-resident Holder to pay the Corporation all amounts owing under subsection 2.12(d) is a personal obligation of the non-resident Holder and shall not be assumed by or deemed to be assumed by any subsequent transferee of the Notes held by such non-resident Holder. The Trustee shall in no way be liable for any amounts becoming payable to the Corporation pursuant to Section 2.12(d).

	(g)		The Trustee shall be entitled to withhold delivery of certificates in respect of Notes and Common Shares to which a transferee of Notes may be entitled, until all amounts owing pursuant to subsection 2.12(d) have been paid. Notwithstanding the foregoing, failure to withhold such delivery shall not in any way result in the Trustee becoming liable for such amount.

	(a)		Notes of any denomination may be exchanged for Notes of any other authorized denomination or denominations, any such exchange to be for Notes of an equivalent aggregate principal amount. Any exchange of Notes may be made at the offices of the Trustee or at the offices of any registrar where registers are maintained for the Notes pursuant to the provisions of section 2.10. Any Notes tendered for exchange shall be surrendered to the Trustee or appropriate registrar and shall be cancelled.

	(b)		Upon the occurrence of an Exchange Tax Event the Corporation may, subject to and in accordance with the provisions of Article 9, call a special meeting of Holders to consider an exchange of any series of Notes for a new series of Notes, having such terms and conditions as approved by a simple majority of Holders.

	(c)		Except as herein otherwise provided, upon any exchange of Notes of any denomination for other Notes and upon any transfer of Notes, the Trustee or other registrar may make a sufficient charge to reimburse it for any stamp or security transfer taxes or other governmental charge required to be paid and, in addition, a reasonable charge for its services and payment of the said charge shall be made by the party requesting such exchange or transfer as a condition precedent thereto.

	(d)		Notwithstanding the foregoing provisions of this section 2.14, no charge shall be made to a Holder thereunder for any exchange or transfer of any Note applied for within a period of 30 days from the date of this Note Indenture.
