The Corporation may from time to time designate alternate or additional places as the Convertible Note Agency and shall give notice to the Trustee of any change of the Convertible Note Agency. 3.2 Effect of Exercise of Convertible Notes (a) Upon the exercise of Convertible Notes pursuant to Section 3.1 or Section 3.7, and subject to Section 3.3 the aggregate principal amount of Convertible Debentures into which Convertible Notes are exercised shall be deemed to have been issued and the Person or Persons to whom such Convertible Debentures are to be issued shall be deemed to have become the holder or holders of record of such aggregate principal amount of Convertible Debentures on the Exercise Date or, if the transfer registers of the Corporation shall be closed on such date, on the date on which such transfer registers are reopened. (b) Subject to Section 3.7, within five Business Days after the Exercise Date with respect to a Convertible Note, the Corporation shall cause to be mailed or delivered to the Person or Persons in whose name or names the Convertible Debentures are to be issued, in such aggregate principal amount or number as specified in the applicable Exercise Form, at the address specified in such Exercise Form or, if so specified in such Exercise Form, delivered at the Convertible Note Agency where the applicable Convertible Note Certificate was -18- surrendered, a certificate or certificates for the appropriate aggregate principal amount of Convertible Debentures into which such Convertible Note is exercised. 3.3 Partial Exercise of Convertible Notes; Fractions (a) The holder of any Convertible Notes may acquire an aggregate principal amount of Convertible Debentures less than the aggregate principal amount which the holder is entitled to acquire pursuant to any surrendered Convertible Note Certificate for exercise. In the event of any exercise of an aggregate principal amount of Convertible Notes less than the aggregate principal amount into which a Convertible Note is exercisable the holder of the Convertible Notes upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new Convertible Note Certificate in respect of the balance of the principal amount of Convertible Notes represented by the unexercised portion of the surrendered Convertible Note Certificate. (b) Notwithstanding anything herein contained, the Corporation shall not be required, upon the exercise of any Convertible Notes, to issue Convertible Debentures in denominations of less than $1,000 and multiples thereof or to distribute certificates which evidence Convertible Debentures other than in $1,000 denominations and multiples thereof. 3.4 Exercise by Certain Persons Restricted The Convertible Notes may not be exercised by any Person resident in a jurisdiction which is not a Qualifying Jurisdiction unless the distribution of Convertible Debentures to such Person can be lawfully made without the Corporation being required to qualify such distribution in any manner under applicable law. 3.5 Reliance By Trustee The Trustee shall have no obligation to ensure or verify compliance with any Applicable Legislation or regulatory requirements on the issue, exercise or transfer of any Convertible Notes or any underlying Convertible Debentures or Common Shares or other securities issuable upon the exercise of any Convertible Notes. The Trustee shall be entitled to process all proffered transfers and exercises of Convertible Notes upon the presumption that such transfers or exercises are permissible pursuant to all Applicable Legislation and regulatory requirements and the terms of the Indenture and the related Convertible Note Certificates, provided that transfers and exercises of Convertible Notes, or the underlying Convertible Debentures or Common Shares or other securities issuable upon the exercise of any Convertible Notes, bearing the U.S. Legend may only be processed by the Trustee upon written instruction of the Corporation to the Trustee, which instruction may be based, in the Corporation's discretion, upon certificates, opinions and other documentation of the holders of such Convertible Notes or underlying Convertible Debentures or Common Shares. The Trustee may assume for the purposes of this Indenture that the address on the register of Convertible Noteholders of any Convertible Notes is the Convertible Noteholder's actual address and is also determinative of the Convertible Noteholder's residency and that the address of any transferee to whom any Convertible Notes or -19- underlying Convertible Debentures or Common Shares or other securities issuable upon the exercise of any Convertible Notes are to be registered, as shown on the transfer document, is the transferee's actual address and is also determinative of the transferee's residency. 3.6 Expiration of Convertible Notes (a) Subject to Section 3.7, immediately after the Time of Expiry, all rights to acquire Convertible Debentures under any Convertible Note in respect of which such right shall not have been exercised shall cease and terminate, and, subject to Section 3.7, such Convertible Note shall be void and of no further force or effect. (b) If for any reason, the exercise of Convertible Notes in accordance with the terms hereof is prohibited by law or does not take place as contemplated herein (including by order of any securities regulatory authority or court of competent jurisdiction) such Convertible Notes shall, notwithstanding anything to the contrary herein contained, remain valid and outstanding, and shall continue to bear interest at the rate herein provided and shall be due and payable in full on the sixth Business Day following the Expiry Date provided the Convertible Notes are then outstanding. 3.7 Accounting and Recording (a) Any securities or other instruments, from time to time received by the Trustee shall be received in trust for, and shall be segregated and kept apart by the Trustee in trust for, the Corporation. (b) The Trustee shall record the particulars of Convertible Notes exercised, which particulars shall include the names and addresses of the Persons who become holders of Convertible Debentures on the exercise thereof and the Exercise Date, if any, in respect thereof. The Trustee shall provide such particulars in writing to the Corporation within five Business Days of any request by the Corporation therefor. 3.8 Automatic Exercise Any Convertible Notes which are not exercised prior to the Expiry Time shall be deemed to be exercised by the holders thereof immediately prior to the Expiry Time to convert Convertible Notes into Convertible Debentures without any further action on behalf of such holder. Following such exercise, such Convertible Notes shall be cancelled and of no further force and effect other than evidence of entitlement to receive the Convertible Debentures resulting from the conversion of Convertible Notes upon the automatic exercise of any Convertible Notes, which shall be issued upon the surrender of the related Convertible Note Certificate accompanied with the duly completed and executed Exercise Form, either by personal delivery thereof to the Trustee at the Convertible Note Agency or at any other place or places that may be designated by the Corporation with the approval of the Trustee, or, if sent by mail upon actual receipt thereof by the Trustee at the Convertible Note Agency. Within two Business Days of the Expiry Date, the Corporation shall notify holders of the Convertible Notes that have -20- not exercised such Convertible Notes prior to the Time of Expiry that such Convertible Notes have been automatically exercised and converted. 3.9 Securities Restrictions Notwithstanding anything herein contained, Convertible Debentures will only be issued upon exercise of any Convertible Note in compliance with the securities laws of any applicable jurisdiction, and without limiting the generality of the foregoing, in the event that the Convertible Notes are exercised pursuant to Section 3.1 prior to the issuance of a Receipt, the certificates representing the Convertible Debentures thereby issued, or any Common Shares into which the Convertible Debentures are converted, will bear such legend as may, in the opinion of counsel to the Corporation, be necessary in order to avoid a violation of any securities laws of any province in Canada or to comply with the requirements of any stock exchange on which the Common Shares are listed, provided that if, at any time, in the opinion of counsel to the Corporation, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate, at the holders expense, provides the Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel satisfactory to the Corporation, acting reasonably) to the effect that such holder is entitled to sell or otherwise transfer such Convertible Debentures or Common Shares in a transaction in which such legends are not required, such legended certificate may thereafter be surrendered to the Corporation in exchange for a certificate which does not bear such legend. ARTICLE 4 - REDEMPTION 4.1 Redemption (a) If the Corporation has not obtained a Receipt on or before the Receipt Deadline, then: (i) each Convertible Noteholder will be entitled to elect (the "Redemption Election") to cause the Corporation to redeem all, but not less than all, the Convertible Notes held by such Convertible Noteholder at a price (the "Redemption Price") per Convertible Note equal to the principal amount thereof, together with accrued and unpaid interest on the principal amount of the Convertible Note so redeemed to but not including the date fixed for redemption (the "Redemption Date"), which date shall not be less than 15 Business Days after the date of receipt or deemed receipt of a Redemption Election Notice (as defined herein) by the Convertible Noteholders; (ii) the Redemption Election may be exercised by delivery to the Corporation of a notice of exercise (a "Redemption Election Notice") substantially in the form attached hereto as Schedule "C" prior to 5:00 p.m. (Toronto time) on the third Business Day immediately preceding the Redemption Date by the Convertible Noteholders; (iii) notwithstanding Section 4.1(a)(i), in the event that Convertible Noteholders representing in the aggregate more than 50% of the aggregate -21- principal amount of the Convertible Notes outstanding on September 28, 2001 elect to cause the Corporation to redeem the Convertible Notes held by such Convertible Noteholders, all outstanding Convertible Notes shall be redeemed (a "Mandatory Redemption") by the Corporation on the Redemption Date at a price per Convertible Note equal to the Redemption Price; (iv) the Corporation shall, on or before October 2, 2001, deliver or cause to be delivered to each Convertible Noteholder and the Trustee a notice stating (A) that a Receipt was not obtained by the Corporation prior to the Receipt Deadline, (b) that each Convertible Noteholder has the rights set forth in, and shall be subject to the provisions of, Sections 4.1(a)(i), (ii) and (iii), as applicable, and (C) the Redemption Date, and including a Redemption Election Notice in the form attached hereto as Schedule "C".

(b) Upon compliance by the Corporation with the provisions of Section 4.1(a)(v), all of the outstanding Convertible Notes so called for redemption shall thereupon become due and payable at the Redemption Price on the Redemption Date and from and after the Redemption Date such Convertible Notes shall not be considered as outstanding hereunder and interest on such Convertible Notes shall cease. (c) From the sums deposited with the Trustee by the Escrow Agent pursuant to the Escrow Direction, the Trustee shall deliver, pay or cause to be delivered and paid to the holders of Convertible Notes so redeemed, upon surrender of such Convertible Notes, the moneys to which the Convertible Noteholders are respectively entitled on redemption. -22- (d) If the Trustee determines that the sums deposited with the Trustee by the Escrow Agent will not be sufficient to allow the Trustee to pay the Redemption Price with respect to Convertible Notes to be redeemed in accordance with this Section 4.1, the Trustee shall give notice of such determination to the Corporation and the Corporation shall, within three Business Days of the date upon which such notice is received, pay to the Trustee such amount as shall be sufficient, together with the sums deposited with the Trustee by the Escrow Agent, to allow the Trustee to pay the Redemption Price with respect to Convertible Notes to be redeemed in accordance with this Section 4.1. ARTICLE 5 - RIGHTS OF THE CORPORATION AND COVENANTS. REPRESENTATIONS AND WARRANTIES 5.1 Optional Purchases by the Corporation The Corporation may from time to time purchase with the consent of the Convertible Noteholder, by private contract or otherwise any of the Convertible Notes. Any such purchases shall be offered to all Convertible Noteholders on a pro rata basis. Any such purchase shall be made at the lowest price or prices at which, in the opinion of the directors, such Convertible Notes are then obtainable from such Convertible Noteholder, plus reasonable costs of purchase, and may be made in such manner, from such Persons and on such other terms as the Corporation may determine.

then, in each and every such event, if such event is continuing, subject to Section 6.3 and Section 7.10(d), the Trustee may in its discretion and shall, upon receipt of a Convertible Noteholders' Request, declare the principal of, and interest on, all Convertible Notes then outstanding and all other moneys outstanding hereunder to be due and payable, and the same shall forthwith become immediately due and payable to the Trustee, anything therein or herein to the contrary notwithstanding, and the Corporation shall forthwith pay to the Trustee for the benefit of the Convertible Noteholders the amount of the principal of, and interest then accrued on, all of the Convertible Notes then outstanding and all other moneys outstanding hereunder, together with interest thereon, at the rate of interest borne by the Convertible Notes from the date of the said declaration until payment is received by the Trustee and such payment when made shall be deemed to have been made on such Convertible Notes and shall be applied as provided in Section 6.5. 6.2 Notice of Events of Default If an Event of Default shall occur and be continuing the Trustee shall, as soon as reasonably possible but in any event within 15 days after it becomes aware of the occurrence of such Event of Default, give notice of such Event of Default, to the Convertible Noteholders in the manner provided in Article 10; provided that, notwithstanding the foregoing, unless the Trustee shall have been requested to do so pursuant to a Convertible Noteholders' Request, the Trustee shall not be required to give such notice, if the Trustee, in good faith, reasonably believes that it is in the best interests of the Convertible Noteholders to withhold such notice and shall have so informed the Corporation in writing. -29- 6.3 Waiver of Default Upon the happening of any Event of Default, except default in payment of principal, and in addition to the powers exercisable by the Convertible Noteholders by Extraordinary Resolution, the holders of not less than 51% in principal amount of all the Convertible Notes which shall then be outstanding shall have power, by an instrument or instruments in writing or by affirmative votes of such holders at a meeting duly convened and held as hereinafter provided, to cancel any declaration made by the Trustee pursuant to Section 6.1 or to require the Trustee to waive the default, or both, and such declaration shall thereupon be cancelled or the Trustee shall thereupon waive the default, in either case, upon such terms and conditions as such holders shall prescribe. So long as it has not become bound as provided in this Article 6 to declare the principal of and interest on all the Convertible Notes then outstanding to be due and payable, or to obtain and enforce payment of the same, the Trustee shall have the power to waive any default arising hereunder if, in the reasonable opinion of the Trustee, acting in good faith, the same shall have been cured, or adequate satisfaction made therefor, upon such terms and conditions as the Trustee may deem advisable. Provided always that no act or omission either of the Trustee or of the Convertible Noteholders in the premises shall extend to or be taken in any manner whatsoever to affect any subsequent default or the rights resulting therefrom. 6.4 Right of Trustee to Enforce Payment (a) Subject to the provisions of Section 6.3, if the Corporation shall fail to pay to the Trustee, on demand, the principal of and interest on all Convertible Notes then outstanding which shall have been declared by the Trustee to be due and payable pursuant to Section 6.1, together with any other amounts due hereunder, the Trustee may in its discretion and shall upon receipt of a Convertible Noteholders' Request and upon being funded and indemnified 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 of and interest on all the Convertible Notes then outstanding together with any other amounts due hereunder, by any remedy provided by law either by legal proceedings or otherwise. (b) 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 of the Convertible Notes, 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 of the Convertible Notes 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 of the Convertible Notes by taking and holding the same shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective holders of the Convertible Notes with authority to make or file in the respective names of the holders of the Convertible Notes or on behalf of the holders of the Convertible Notes as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the holders of -30- the Convertible Notes themselves, any proof of debt, amendment of proof of debt, claim, petition or other document in any proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any such other papers and documents and to do and perform any and all such acts and things for and on behalf of such holders of the Convertible Notes, as may be necessary or advisable in the opinion of the Trustee, in order to have the respective claims of the Trustee and of the holders of the Convertible Notes 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 Indenture shall be deemed to give to the Trustee, unless so authorized by Extraordinary Resolution, any right to accept or consent to any plan of reorganization or otherwise by action of any character in such proceeding to waive or change in any way any right of any Convertible Noteholder.

In such event, the holder shall be entitled to receive a new Convertible Note Certificate for the unexercised portion of the Convertible Notes represented hereby. Convertible Debentures will only be issued in denominations of $1,000 and multiples thereof. At the Time of Expiry on the Expiry Date, the Convertible Notes represented hereby shall be deemed to have been exercised immediately prior to the Time of Expiry (unless the Convertible Notes represented hereby have been previously exercised) to convert such Convertible Notes into Convertible Debentures and the certificates representing such Convertible Debentures will be issued to the holder of this Convertible Note Certificate upon surrender to the Trustee at the principal office of the Trustee in the City of Toronto and thereupon the Convertible Notes represented hereby be deemed to be cancelled and of no further force and effect. On the second Business Day following the Expiry Date, the Corporation shall notify -3- holders of the Convertible Notes that if they have not exercised such Convertible Notes prior to the Time of Expiry that such Convertible Notes have been deemed to be exercised. The Convertible Notes represented by this certificate are issued under and pursuant to a Convertible Note Trust Indenture (hereinafter referred to as the "Indenture") made as of August 30, 2001 between the Corporation and the Trustee. Reference is made to the Indenture and any instruments supplemental thereto for a full description of the rights of the holder of this Convertible Note Certificate and the terms and conditions upon which the Convertible Notes are, or are to be, issued and held, with the same effect as if the provisions of the Indenture and all instruments supplemental thereto were herein set forth. By acceptance hereof, the holder assents to all provisions of the Indenture. Capitalized terms used herein have the same meaning as in the Indenture, unless otherwise defined herein. To the extent the terms and conditions set forth in this Convertible Note Certificate conflict with the terms and conditions of the Indenture, the Indenture shall prevail. The Corporation will furnish to the holder of this Convertible Note Certificate, upon request and without charge, a copy of the Indenture. The Convertible Notes represented hereby shall bear interest from the Effective Date or the date of issue, whichever is later, at the rate of 7.25% per annum, after as well as before default, with interest on overdue interest at the same rate. Interest shall be based on a 365 or 366 day year, as the case may be, and shall be calculated semi-annually not in advance from the Effective Date or the date of issue of the Convertible Notes, whichever is later, or from the last interest payment date to which interest has been paid or made available for payment on the Convertible Notes, whichever is later, and shall be paid in like money semi-annually on February 28 and August 30, commencing on February 28, 2002, unless this Convertible Note shall have been previously exercised as duly provided for. As the interest on the Convertible Notes becomes due (except interest payable at maturity which may be paid upon presentation and surrender of such Convertible Notes for payment), the Corporation, either directly or indirectly through the Trustee, shall forward or cause to be forwarded by prepaid ordinary mail at least three (3) Business Days prior to the interest payment date, to the holder for the time being, or, in the case of joint holders, to one of such joint holders (failing written instructions to the contrary from all of such joint holders), at the holder's address appearing on the register, a cheque for such interest (less any tax required to be deducted), payable to or to the order of such holder or holders and negotiable at par. The forwarding of such cheque shall satisfy and discharge the liability for the interest upon the Convertible Notes to the extent of the sums represented thereby (plus the amount of any tax deducted as aforesaid) unless such cheque is not paid on presentation; provided that in the event of the non-receipt of such cheque by such registered holder or the loss or destruction thereof, the Corporation, upon being furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, shall issue or cause to be issued to such registered holder a replacement cheque for the amount of such cheque. If for any reason, the exercise of Convertible Notes in accordance with the terms hereof is prohibited by law or does not take place as contemplated in the Indenture (including by order of any securities regulatory authority or court of competent jurisdiction) such Convertible Notes shall, notwithstanding anything to the contrary herein contained, remain valid and outstanding, -4- and shall continue to accrue interest at the rate herein provided and shall be due and payable in full on the sixth Business Day following the Expiry Date. The registered holder of this Convertible Note Certificate may, at any time prior to the Time of Expiry, upon surrender hereof to the Trustee at its principal office in the City of Toronto, exchange this Convertible Note Certificate for other Convertible Note Certificates entitling the holder to acquire, in the aggregate, the same aggregate principal amount of Convertible Debentures as may be acquired on exercise of the Convertible Notes represented by this Certificate. The holding of the Convertible Notes evidenced by this Convertible Note Certificate shall not entitle the holder to any right or interest in respect of the Corporation except as expressly provided in the Indenture and in this Convertible Note Certificate. The Indenture provides that all holders of Convertible Notes shall be bound by any resolution passed at a meeting of the holders held in accordance with the provisions of the Indenture and resolutions signed by the holders of Convertible Notes of 66"% of the principal amount of all then outstanding Convertible Notes. Subject to the Corporation's right to purchase the Convertible Notes under the Indenture and to any restriction under applicable law or policy of any applicable regulatory body, the Convertible Notes evidenced by this Convertible Note Certificate may be transferred on the register kept at the principal offices of the Trustee in the City of Toronto by the registered holder hereof or its legal representatives or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee, only upon compliance with the conditions prescribed in the Indenture and upon compliance with such reasonable requirements as the Trustee may prescribe. This Convertible Note Certificate shall not be valid for any purpose whatever unless and until it has been certified by or on behalf of the Trustee. -5- IN WITNESS WHEREOF the Corporation has caused this Convertible Note Certificate to be signed by its duly authorized officer as of the 30th day of August, 2001.
