	(d)		reduces, combines or consolidates its outstanding Common Shares into a smaller number of Common Shares,

(any of such events in subsections (a), (b), (c) and (d) being called a “Common Share Reorganization”), then the Conversion Price then in effect will be adjusted effective immediately on the effective date or record date for the happening of a Common Share Reorganization, as the case may be, at which the holders of Common Shares are determined for the purpose of the Common Share Reorganization, so that it will equal the price determined by multiplying the Conversion Price in effect immediately prior to such effective date or record date by a fraction, the numerator of which will be the total number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization and the denominator of which will be the total number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had all such securities been exchanged for or converted into Common Shares on such effective date or record date).

(3) If and whenever at any time after the date hereof and prior to the Maturity Date, the Corporation fixes a record date for the issue of rights, options or warrants to the holders of all or substantially all of the outstanding Common Shares under which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (the “Rights Period”), to subscribe for or purchase Common Shares or securities exchangeable for or convertible into Common Shares at a price per share to the holder (or at an exchange price or conversion price per share during the Rights Period to the holder in the case of securities exchangeable for or convertible into Common Shares) which is less than 95% of the Current Market Price for the

- 24 -

Common Shares on such record date (any of such events being called a “Rights Offering”), then the Conversion Price will be adjusted effective immediately after the end of the Rights Period so that it will equal the price determined by multiplying the Conversion Price in effect immediately prior to the end of the Rights Period by a fraction:

(a)

the numerator of which will be the aggregate of:

	(i)		the total number of Common Shares outstanding as of the record date for the commencement of the Rights Offering, and

	(ii)		a number determined by dividing (I) either (x) the product of the number of Common Shares issued or subscribed for during the Rights Period upon the exercise of the rights, warrants or options under the Rights Offering and the price at which such Common Shares are offered for such issue or subscription, or, as the case may be, (y) the product of the exchange price or conversion price of such securities exchangeable for or convertible into Common Shares and the number of Common Shares for or into which the securities so offered pursuant to the Rights Offering could have been exchanged or converted during the Rights Period, by (II) the Current Market Price of the Common Shares as of the record date for the commencement of the Rights Offering, and

(b)

the denominator of which will be the number of Common Shares outstanding, or the number of Common Shares which would be outstanding if all the exchangeable or convertible securities were exchanged for or converted into Common Shares during the Rights Period, after giving effect to the Rights Offering and including the number of Common Shares actually issued or subscribed for during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering.

Any Debentureholder who has exercised the right to convert to Common Shares in accordance with Article 4 during the period beginning immediately after the record date for a Rights Offering and ending on the last day of the Rights Period for the Rights Offering will, in addition to the Common Shares to which that holder would otherwise be entitled upon such conversion, be entitled to that number of additional Common Shares equal to the result obtained when the difference, if any, between the Conversion Price in effect immediately prior to the end of such Rights Offering and the Conversion Price as adjusted for such Rights Offering pursuant to this Section 5.01(3) is multiplied by the number of Common Shares received upon the conversion of the Debentures held by such Holder during such period, and the resulting product is divided by the Conversion Price as adjusted for such Rights Offering pursuant to this Section 5.01(3); provided that the provisions of Section 4.03 will be applicable to any fractional interest in a Common Share to which such Holder might otherwise be entitled under the foregoing provisions of this subsection. Such additional Common Shares will be deemed to have been issued to the Debentureholder immediately following the end of the Rights Period and a certificate for such additional Common Shares will be delivered to such Holder within 15 Business Days following the end of the Rights Period. To the extent that any such rights, options or warrants are not so exercised on or before the expiry thereof, the Conversion Price will be readjusted to the Conversion Price which would then be in effect based on the number of Common Shares (or the

- 25 -

securities convertible into or exchangeable for Common Shares) actually delivered on the exercise of such rights, options or warrants.

(4) If and whenever at any time after the date hereof and prior to the Maturity Date, the Corporation fixes a record date for the issue or the distribution to the holders of all or substantially all of the outstanding Common Shares of (i) securities of the Corporation, including rights, options or warrants to acquire securities of the Corporation or any of its property or assets and including cash and evidences of indebtedness; or (ii) any property or other assets, including cash and evidences of indebtedness, and if such issuance or distribution does not constitute a Dividend Paid in the Ordinary Course, a Common Share Reorganization, a Rights Offering or a distribution contemplated by Section 5.01(3) (any of such non-excluded events being called a “Special Distribution”), then the Conversion Price will be adjusted effective immediately after such record date so that it will equal the price determined by multiplying the Conversion Price in effect on such record date by a fraction:

(a)

the numerator of which will be:

	(i)		the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date; less

	(ii)		the fair market value, as determined by action by the Board of Directors (whose determination, subject to the consent of a Recognized Stock Exchange, will be conclusive), to the holders of Common Shares of such securities or property or other assets so issued or distributed in the Special Distribution; and

(b)

the denominator of which will be the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date.

To the extent that any Special Distribution is not so made, the Conversion Price will be readjusted effective immediately to the Conversion Price which would then be in effect based upon such securities or property or other assets as actually distributed.

(5) If and whenever at any time after the date hereof and prior to the Maturity Date, there is a reclassification of the Common Shares at any time outstanding or change of the Common Shares into other shares or into other securities or other capital reorganization (other than a Common Share Reorganization), or a consolidation, amalgamation or merger of the Corporation with or into any other corporation or other entity (other than a vertical short-form amalgamation with one or more of its Wholly-Owned Subsidiaries pursuant to the Canada Business Corporations Act), or a transfer of the undertaking or assets of the Corporation as an entirety or substantially as an entirety to another corporation or other entity in which the holders of Common Shares are entitled to receive shares, other securities or other property (any of such events being called a “Capital Reorganization”), any Holder of Debentures who exercises the right to convert Debentures into Common Shares pursuant to Debentures then held after the effective date of such Capital Reorganization will be entitled to receive, and will accept for the same aggregate consideration in lieu of the number of Common Shares to which such Holder was previously entitled upon such conversion, the aggregate number of shares, other securities or other

- 26 -

property that such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, the holder had been the registered holder of the number of Common Shares to which such holder was previously entitled upon conversion subject, however, to any requirements necessary to ensure that the interest payable on the Debentures will be and will remain exempt from Canadian withholding tax including the requirement in effect on the date hereof for so long as such requirement is in effect that a Holder of Debentures will not be entitled to receive shares, other securities or property other than securities that are “prescribed securities” as defined in Regulation 6208 to the Income Tax Act (Canada) on or prior to five years after the date of issue of the Debentures. Subject to the preceding sentence, the Corporation will take all steps necessary to ensure that, on a Capital Reorganization, the Holders of Debentures will receive the aggregate number of shares, other securities or other property to which they are entitled as a result of the Capital Reorganization. Appropriate adjustments will be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Article 5 with respect to the rights and interests thereafter of Holders of Debentures to the end that the provisions set forth in this Article 5 will thereafter correspondingly be made applicable as nearly as may reasonably be in relation to any shares, other securities or other property thereafter deliverable upon the conversion of any Debenture. Prior to or concurrent with effecting a Capital Reorganization, the Corporation will enter into an indenture supplemental hereto approved by action of the Board of Directors and by the Trustee, relying on advice of counsel, that will set forth an appropriate adjustment to give effect to this Section 5.01(5), in which event such adjustment will for all purposes be conclusively deemed to be an appropriate adjustment, subject to any required prior consent of a Recognized Stock Exchange.

(6) If the purchase price provided for in any rights, options or warrants (the “Rights Offering Price”) referred to in Sections 5.01(3) or (4) is decreased, the Conversion Price will forthwith be changed so as to decrease the Conversion Price to the Conversion Price that would have been obtained if the adjustment to the Conversion Price made under Section 5.01(3) or (4), as the case may be, with respect to such rights, options or warrants had been made on the basis of the Rights Offering Price as so decreased, provided that the terms of this Section 5.01(6) will not apply to any decrease in the Rights Offering Price resulting from terms in any such rights, options or warrants designed to prevent dilution except to the extent that the resulting decrease in the Conversion Price under this Section 5.01(6) would be greater than the decrease, if any, in the Conversion Price to be made under the terms of this Section 5.01(6) by virtue of the occurrence of the event giving rise to such decrease in the Rights Offering Price.

(7) In any case in which this Section 5.01 requires that an adjustment will become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the Holder of any Debenture converted after such record date and before the occurrence of such event the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event, provided, however, that the Corporation will deliver to such Holder evidence of such Holder’s right to receive such additional Common Shares upon the occurrence of such event and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the date of conversion or such later date on which such Holder would, but for the provisions of this Section 5.01(7), have become the holder of record of such additional Common Shares.

- 27 -

5.02 Other Adjustment of Conversion Price.

If the Corporation will take any action affecting the Common Shares, other than an action described in Sections 5.01(2), (3), (4)or (6) but including an action under Section 5.01(5), that results in a Holder of Debentures being unable, for any period of time, to exercise conversion privileges that it would otherwise be permitted to exercise due to requirements necessary to ensure that the Debentures will be and will remain exempt from Canadian withholding tax, the Conversion Price may be adjusted in such manner and at such time, or such other adjustment to the conversion privilege may be made, as the Board of Directors determine to be equitable in the circumstances, subject to any required prior consent of a Recognized Stock Exchange and subject, however, to any requirements necessary to ensure that the interest payable on the Debentures will be and will remain exempt from Canadian withholding tax. Failure of the Board of Directors to take any such action will be conclusive evidence that the Board of Directors has determined that it is equitable to make no adjustment in the circumstances.

5.03 Rules Regarding Calculation of Adjustment of Conversion Price.

For the purposes of Sections 5.01 and 5.02:

(1) The adjustments provided for in Sections 5.01 and 5.02 are cumulative and will be computed to the nearest one-tenth of one cent and will be made successively whenever an event referred to therein occurs, subject to the following provisions of this Section 5.03.

(2) No adjustment in the Conversion Price will be required unless the cumulative effect of such adjustment would result in a change of at least 1% in the prevailing Conversion Price; provided, however, that any adjustments that, except for the provisions of this Section 5.03 would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustment.

(3) No adjustment in the Conversion Price will be required upon the issuance from time to time of Common Shares pursuant to the Corporation’s stock option plans or share purchase plan, or any dividend reinvestment plan, as such plans may be replaced, supplemented or further amended from time to time, or in respect of the New Rights Offering (as defined in the Plan).

(4) No adjustment in the Conversion Price will be made in respect of any of the events referred to in Section 5.01(2)(a) and (b), Section 5.01(3), or Section 5.01(4), if Debentureholders are entitled to participate in such event on the same terms, mutatis mutandis, as if they had converted their Debentures prior to or on the effective date or record date of such event. Any such participation will be subject to any required prior consent of a Recognized Stock Exchange.

(5) If at any time a dispute arises with respect to adjustments provided for in Section 5.01, such dispute will be conclusively determined, subject to the consent of a Recognized Stock Exchange, by the Corporation’s auditors, or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by action of the Board of Directors and any such determination will be binding upon the Corporation, the Trustee, the Debentureholders and shareholders of the Corporation; such auditors or accountants will be given access to all necessary records of the Corporation. If any such determination is made, the Corporation will deliver a Certificate of the Corporation to the Trustee describing such

- 28 -

determination, and the Trustee will be entitled to act and rely upon such Certificate of the Corporation.

(6) If the Corporation sets a record date to determine the holders of Common Shares for the purpose of entitling them to receive any dividend or distribution or sets a record date to take any other action and thereafter and before the distribution to such shareholders of any such dividend or distribution or the taking of any other action, legally abandons its plan to pay or deliver such dividend or distribution or take such other action, then no adjustment in the Conversion Price will be made.

(7) In the absence of a resolution of the Board of Directors fixing a record date for a Special Distribution or Rights Offering, the Corporation will be deemed to have fixed as the record date therefor the date on which the Special Distribution or Rights Offering is effected.

For greater certainty, Debentureholders will have no right to convert Debentures into any security other than Common Shares unless an appropriate adjustment is made by and set forth in an indenture supplemental hereto.

5.04 Certificate as to Adjustment.

The Corporation will from time to time, immediately after the occurrence of any event that requires an adjustment or readjustment as provided in Section 5.01 or 5.02, deliver a Certificate of the Corporation to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, and the Trustee will be entitled to act and rely upon such Certificate of the Corporation. Such Certificate of the Corporation and the amount of the adjustment specified therein will be conclusive and binding on all parties in interest. Until such Certificate of the Corporation is received by the Trustee, the Trustee may act and be protected in acting on the presumption that no adjustment has been made or is required. Except in respect of any subdivision, reduction, combination or consolidation of the Common Shares contemplated by Section 5.01(2)(a), the Corporation will forthwith give notice to the Debentureholders specifying the event requiring such adjustment or readjustment and the amount thereof, including the resulting Conversion Price; provided that if the Corporation has given notice under Section 5.05 covering all the relevant facts in respect of such event, no such notice need be given under this Section 5.04.

5.05 Notice of Special Matters.

The Corporation covenants that, so long as any Debentures remain outstanding, it will give notice to the Trustee and to the Debentureholders of its intention to fix a record date for any event referred to in Section 5.01(2), (3), (4) or (5) (other than the subdivision, reduction, combination or consolidation of Common Shares contemplated by Section 5.01(2)(a)) or a cash dividend (other than a Dividend Paid in the Ordinary Course) that may give rise to an adjustment in the Conversion Price, or other adjustment, and such notice must specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation will only be required to specify in such notice such particulars of such event as have been fixed and determined on the date on which such notice is given. Such notice must be given not less than 14 days prior to the applicable record date in the case of an event referred to in Sections 5.01(2), (3)

- 29 -

or (4) and 30 days prior to the applicable record date in the case of an event referred to in Section 5.01(5).

5.06 Notice of Expiry of Conversion Right.

The Corporation covenants that, so long as any Debentures remain outstanding, it will give notice to the Trustee and the Debentureholders in the manner provided in the Principal Indenture, not less than 21 days prior to the Maturity Date, of the expiry of the right of the Holders of the Debentures to convert their Debentures.

5.07 Protection of Trustee.

The Trustee, even if it were to act as conversion agent, will not at any time be under any duty or responsibility to any Debentureholder to determine whether any facts exist that may require any adjustment in the Conversion Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same; and will not be accountable with respect to the validity or value (or the kind or amount) of any Common Shares or of any shares or other securities or other property that may at any time be issued or delivered upon the conversion of any Debenture; and the Trustee will not be responsible for any failure of the Corporation to make any cash payment or to issue, transfer or deliver Common Shares or share certificates upon the surrender of any Debenture for the purpose of conversion, or to comply with any of the covenants contained in this Article 5.

ARTICLE 6 — RANKING OF DEBENTURES

6.01 Ranking.

The Corporation covenants and agrees, and each Debentureholder, by its acceptance thereof, likewise agrees, that the payment of the principal of and of any interest on the Debentures ranks pari passu with all Senior Debt whether outstanding on the date of this Second Supplemental Indenture or thereafter incurred.

ARTICLE 7 — ADDITIONAL COVENANTS OF THE CORPORATION WITH RESPECT TO THE DEBENTURES

7.01 Additional Covenants.

(1) The Corporation covenants and agrees with the Trustee for the benefit of the Holders that:

	(a)		it will take all reasonable steps and actions and do all such acts and things as may be required to: (i) as long as it meets the minimum listing requirements of such institutions, maintain the listing and posting for trading of the Debentures and the Common Shares on a Recognized Stock Exchange, and (ii) maintain its status as a reporting issuer, or the equivalent thereof, not in default of the requirements of Applicable Securities Laws of Canada; and

	(b)		it will, at the relevant times and upon exercise of the relevant rights or elections, comply and take all measures necessary to comply at all times with Sections

- 30 -

4.01(3) and 4.02(3) including, make application for any order, ruling, registration or filing or give any notice required under Applicable Securities Laws.

(2) The Trustee will have no obligation to verify information relating to the Corporation’s compliance with this Section 7.01 and may act and rely upon all information provided by the Corporation with respect to such compliance, without independent inquiry.

ARTICLE 8 — SATISFACTION AND DISCHARGE

8.01 Cancellation and Destruction.

All matured Debentures will forthwith after payment thereof be delivered to the Trustee or to a Person appointed by it or by the Corporation with the approval of the Trustee and cancelled. All Debentures cancelled or required to be cancelled under this or any other provision of this Indenture, in the Trustee’s sole discretion, may be destroyed by or under the direction of the Trustee by cremation or otherwise (in the presence of a representative of the Corporation, if the Corporation so requires) and the Trustee will prepare and retain upon request a certificate of such destruction and deliver a duplicate thereof to the Corporation.

8.02 Non-Presentation of Debentures.

If the Holder of any Debenture fails to present the same for payment within 30 days of the date on which the principal thereon or represented thereby becomes payable at maturity or otherwise or fails within such 30 day period to accept payment on account thereof, accept Common Shares issued and delivered pursuant to the provisions hereof or give such receipt therefor, if any, as the Trustee may require:

	(a)		the Corporation will be entitled to pay or issue and deliver, as the case may be, to the Trustee and direct the Trustee to set aside; or

	(b)		in respect of money in the hands of the Trustee that may or should be applied to the payment of the Debentures, the Corporation will be entitled to direct the Trustee to set aside,

the principal and interest, or the Common Shares, as the case may be, in trust to be paid or delivered, as the case may be, without interest to the Holder of such Debenture, upon due presentation or surrender thereof in accordance with the provisions of this Indenture; and thereupon the principal and interest payable on or represented by each Debenture in respect whereof such money or Common Shares have been set aside will be deemed to have been paid and the Holder thereof will thereafter have no right in respect thereof, except that of receiving payment of the money or the Common Shares so set aside by the Trustee upon due presentation and surrender by the Holders of such Debenture, subject always to the provisions of Section 8.03.

8.03 Repayment of Unclaimed Money or Common Shares to Corporation.

Any money or Common Shares in the hands of the Trustee and set aside under Section 8.02 and not claimed by and paid or delivered as provided in Section 8.02, to Holders of Debentures within two years after the date of such setting aside must be repaid or delivered to the Corporation by the Trustee on demand, and thereupon the Trustee will be released from all further

- 31 -

liability with respect to such money and Common Shares and thereafter the Holders of the Debentures in respect of which such money and Common Shares were so repaid or delivered to the Corporation will have no rights in respect thereof, except to obtain payment of the money or delivery of the Common Shares due thereon from the Corporation upon due presentation and surrender by the Holder of such Debentures without interest.

8.04 Release from Covenants.

Upon Written Request and proof being given to the reasonable satisfaction of the Trustee that the principal of all the Debentures and interest thereon and other money payable hereunder have been paid or satisfied or that all the Debentures then outstanding having matured and, such payment having been duly and effectually provided for by payment to the Trustee or otherwise, and upon payment of all costs, charges and expenses properly incurred by the Trustee in relation to these presents and all interest thereon and the remuneration of the Trustee, or upon provision satisfactory to the Trustee being made therefor, the Trustee will, at the request and at the expense of the Corporation, execute and deliver to the Corporation such deeds or other instruments as are requisite to release the Corporation from the terms of the Second Supplemental Indenture and the terms of the Principal Indenture relating to the Debentures, except those relating to the indemnification of the Trustee and issue and delivery of Common Shares in connection with the exercise of rights of conversion pursuant to Article 4.

ARTICLE 9 — COMMON SHARE INTEREST PAYMENT ELECTION

9.01 Interest Payment Election by Delivery of Common Shares to be Liquidated.

(1) Provided that no Event of Default has occurred and is continuing under this Indenture and that all applicable regulatory approvals have been obtained (including any required approval of any stock exchange on which the Common Shares are then listed and any required regulatory approval to permit the Trustee to carry out its obligations under this Section 9.01), the Corporation will have the revocable right, from time to time, to make an Interest Payment Election in respect of all or any part of any Interest Obligation by delivering an Interest Payment Election Notice to the Trustee by no later than the earlier of: (i) the date required by Applicable Law or the rules of any stock exchange on which the Common Shares are then listed, or (ii) the day that is 15 Business Days prior to the Interest Payment Date to which the Interest Payment Election relates.

(2) Upon receipt of an Interest Payment Election Notice, the Trustee will, in accordance with this Article 9 and such Interest Payment Election Notice, deliver Common Share Bid Requests to the investment banks, brokers or dealers identified by the Corporation, in its absolute discretion, in the Interest Payment Election Notice. In connection with the Interest Payment Election, the Trustee will have the power, on behalf of the Corporation, to: (i) accept delivery of the Common Shares from the Corporation and process the Common Shares in accordance with the Interest Payment Election Notice, (ii) accept bids with respect to, and consummate sales of, such Common Shares, each as the Corporation will direct in its absolute discretion, through the investment banks, brokers or dealers identified by the Corporation in the Interest Payment Election Notice, (iii) invest the proceeds of such sales on the direction of the Corporation in Canadian Government Obligations that mature at least three Business Days prior to an applicable Interest Payment Date or use such proceeds to pay all or part of the Interest

- 32 -

Obligation in respect of which the Interest Payment Election was made or both and (iv) perform any other action necessarily incidental thereto.

(3) The Interest Payment Election Notice must provide for, and all bids must be subject to, the right of the Corporation, by delivering written notice to the Trustee at any time prior to the consummation of such delivery and sale of the Common Shares on the Common Share Delivery Date, to withdraw the Interest Payment Election (which will have the effect of withdrawing each related Common Share Bid Request), whereupon the Corporation will be obliged to pay in cash the Interest Obligation in respect of which the Interest Payment Election Notice has been delivered. The Trustee will be fully indemnified by the Corporation in respect of any withdrawal of an Interest Payment Election or any termination of bids or contracts for the issuance or sales of Common Shares entered into by the Trustee on behalf of the Corporation.

(4) Any sale of Common Shares pursuant to this Article 9 may be made to one or more Persons whose bids are solicited, but all such sales with respect to a particular Interest Payment Election will take place concurrently on the Common Share Delivery Date.

(5) The amount received by a Holder of a Debenture in respect of the Interest Obligation will not be affected by whether or not the Corporation elects to satisfy the Interest Obligation pursuant to an Interest Payment Election.

(6) The Trustee must inform the Corporation promptly following receipt of any bid or bids for Common Shares solicited pursuant to the Common Share Bid Requests. The Trustee will accept such bid or bids as the Corporation (in its absolute discretion) directs by Written Order. In connection with any bids so accepted, the Corporation, the Trustee (if required by the Corporation in its absolute discretion) and the applicable bidders must, not later than the Common Share Delivery Date, enter into Common Share Purchase Agreements and will comply with all Applicable Securities Laws, including the securities rules and regulations of any stock exchange on which the Common Shares are then listed. The Corporation will, if so requested by the Trustee, deliver to the Trustee an Opinion of Counsel that such Common Share Purchase Agreements so comply with such Applicable Securities Laws or regulations of any stock exchange on which the Common Shares are then listed. The Corporation will pay all fees and expenses in connection with the Common Share Purchase Agreements including the fees and commissions charged by the investment banks, brokers and dealers and the standard fees of the Trustee generally charged for this service.

(7) Provided that (i) all conditions specified in each Common Share Purchase Agreement to the closing of all sales thereunder have been satisfied, other than the delivery of the Common Shares to be sold thereunder against payment of the purchase price thereof, and (ii) the purchasers under each Common Share Purchase Agreement must be ready, willing and able to perform thereunder, in each case on the Common Share Delivery Date, the Corporation will, on the Common Share Delivery Date, deliver to the Trustee the Common Shares to be sold on such date, an amount in cash equal to the difference between the applicable Interest Obligation and the anticipated net proceeds of the Common Shares to be sold and a Certificate of the Corporation, upon which the Trustee may act and rely absolutely without any further enquiry, to the effect that all conditions precedent to such sales, including those set forth in this Indenture and in each Common Share Purchase Agreement, have been satisfied. Upon such deliveries, the Trustee will consummate such sales on such Common Share Delivery Date by the delivery of the Common

- 33 -

Shares to such purchasers against payment to the Trustee in immediately available funds of the purchase price therefor.

(8) The Trustee will, on the Common Share Delivery Date, use the sale proceeds of the Common Shares (together with any cash received from the Corporation) to purchase, on behalf of and for the account of the Corporation and on the direction of the Corporation in writing, Canadian Government Obligations that mature at least three Business Days prior to the applicable Interest Payment Date and that the Trustee is required to hold until maturity (the “Common Share Proceeds Investment”) and will, on such date, deposit the balance, if any, of such sale proceeds in the Property Account for such Debentures. At least one Business Day prior to the Interest Payment Date, the Trustee will deposit amounts from the proceeds of the Common Share Proceeds Investment in the Property Account to bring the balance of the Property Account to the Interest Payment Election Amount. On the Interest Payment Date, the Trustee will pay the funds held in the Property Account to the Holders of record of the Debentures on the Interest Payment Date (less such amount of Taxes as determined by the Corporation as required to be deducted, if any) and, provided that there is no Event of Default, will remit amounts, if any, in respect of income earned on the Common Share Proceeds Investment or otherwise in excess of the Interest Payment Election Amount to the Corporation.

(9) Neither the making of an Interest Payment Election nor the consummation of sales of Common Shares on a Common Share Delivery Date will (i) result in the Holders of the Debentures not being entitled to receive on the applicable Interest Payment Date cash in an aggregate amount equal to the Interest Obligation payable on such date, or (ii) entitle such Holders to receive any Common Shares in satisfaction of such Interest Obligation.

9.02 Interest Payment Election by Delivery of Common Shares

(1) Provided that all applicable regulatory approvals have been obtained (including any required approval of any stock exchange on which the Debentures are then listed), the Corporation may, at its option, pay all, or any part, of any Interest Obligation by delivering to the Holders, Common Shares in lieu of cash payments of interest pursuant to Section 2.08 and the terms of the Debentures (the “Common Share Interest Payment Election”) by giving notice (the “Common Share Interest Payment Election Notice”) to the Trustee by no later than the earlier of: (i) the date required by Applicable Law or the rules of any stock exchange on which the Debentures and Common Shares are then listed, or (ii) the day that is 15 Business Days prior to the record date for the Interest Payment Date to which the applicable interest payment relates.

(2) The Corporation will, not less than three Business Days prior to the applicable Interest Payment Date, deliver to Holders that number of fully paid and non-assessable Common Shares obtained by dividing the interest amount not paid in cash by 90% of the VWAP of the Common Shares on the TSX for the 20 consecutive Trading Days ending on the fifth Trading Day prior to the applicable Interest Payment Date; provided that the Corporation may at its option make any interest payment not exceeding $1,000 to any Holder in money.

(3) The Corporation will be required to provide the Common Share Interest Payment Election Notice only if it determines to exercise the Common Share Interest Payment Election.

- 34 -

(4) The Corporation’s right to exercise the Common Share Interest Payment Election will be conditional upon the following conditions being met on the date that is three Business Days preceding the applicable Interest Payment Maturity Date:

	(a)		all applicable regulatory approvals have been obtained (including any required approval of any stock exchange on which the Debentures are then listed);

	(b)		the Common Shares to be issued on exercise of the Common Share Interest Payment Election will be issued from treasury of the Corporation and will be Freely Tradeable in each province and territory of Canada and fully paid and non-assessable;

	(c)		the listing or quoting of such additional Common Shares on a Recognized Stock Exchange;

	(d)		the Corporation being a reporting issuer or equivalent in good standing or equivalent under Applicable Securities Laws in the Province of Ontario and the other jurisdictions in which the beneficial Holders of the Debentures that are being paid on interest, if reasonably ascertainable, are resident (unless not in Canada);

	(e)		no Event of Default will have occurred and be continuing;

	(f)		the receipt by the Trustee of a Certificate of the Corporation stating that conditions (a), (b), (c), (d) and (e) above have been satisfied and setting forth the number of Common Shares to be delivered; and

	(g)		the receipt by the Trustee of an Opinion of Counsel to the effect that such Common Shares have been duly authorized and, when issued and delivered pursuant to the terms of this Second Supplemental Indenture in payment of the interest amount on the Debentures outstanding, will be validly issued as fully paid and non-assessable, that conditions (b) and (c) above have been satisfied and that, relying exclusively on certificates of good standing issued by the relevant securities regulatory authorities, condition (d) above is satisfied, except that the opinion in respect of condition (d) need not be expressed with respect to those provinces where such certificates are not issued.

ARTICLE 10 – COLLATERAL AND SECURITY

10.01 Collateral and Security Documents; Additional Collateral.

(1) In order to secure the due and punctual payment of the principal of and interest on the Debenture when and as the same will be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, purchase, repurchase, redemption or otherwise, and interest on the overdue principal of and interest (to the extent permitted by law), if any, on the Debentures and the performance of all other obligations of the Corporation to the Holders or the Trustee under this Indenture, the Debentures and any other documents contemplated hereby, the Corporation and the Trustee have simultaneously with the execution of this Indenture entered into the Security Documents. The Trustee and the Corporation hereby agree that the Trustee holds its interest in the

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE CANADIAN DEPOSITORY FOR SECURITIES LIMITED (“CDS”) TO THE CORPORATION OR THE TRUSTEE FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS AN INTEREST HEREIN. THIS CERTIFICATE IS SUBJECT TO A MASTER LETTER OF REPRESENTATION OF THE CORPORATION TO CDS, AS SUCH LETTER MAY BE REPLACED OR AMENDED FROM TIME TO TIME.

STELCO INC. (the “Corporation”), for value received, hereby acknowledges itself indebted and promises to pay to the order of CDS & Co. as nominee for CDS on •, 2016 (the “Maturity Date”), or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture hereinafter mentioned, the principal sum of

• DOLLARS ($•)

in lawful money of Canada, on presentation and surrender of this Debenture at the principal office of BNY Trust Company of Canada in the City of Toronto, and to pay interest on the principal amount hereof at the rate of 9.5% per annum from •, 2006 or from the most recent Interest Payment Date to which interest has been paid or made available for payment on the Debentures then outstanding, whichever is later, in like money in equal quarterly instalments in arrears on •, •, • and • in each year (each such date an “Interest Payment Date”), commencing •, 2006, with overdue interest, if any, at the same rate after as well as before maturity and after as well as before default in payment of principal or interest.

As interest on this Debenture becomes due, the Corporation (except in the case of payment of interest at maturity or on redemption or repurchase, at which time payment of

- 45 -

interest, if any, will be made upon surrender of this Debenture and in the event of conversion, payment of interest, if any, will be made immediately prior to completion of such conversion less in all cases any Taxes required by Applicable Law to be deducted or withheld) will forward or cause to be forwarded by courier or ordinary post to the registered address of the registered Holder of the Debenture for the time being, or in the case of joint Holders to the registered address of one of such joint Holders, or in accordance with the procedures established by CDS if this is a Book-Entry Only Debenture, a cheque or electronic funds transfer for such interest, less any Taxes required by law to be deducted or withheld, payable to the order of such Holder or Holders and negotiable at par. The forwarding of such cheque or electronic funds transfer will satisfy and discharge the liability for interest on this Debenture to the extent of the sum represented thereby (plus the amount of any Taxes deducted or withheld as aforesaid), unless such cheque, if any, is not paid on presentation. The Corporation may, at its option, subject to receipt of all necessary regulatory approvals, pay interest in additional Common Shares in lieu of cash payments of interest and provided that no Event of Default has occurred and is continuing (the “Common Share Interest Payment Election”). The amount received by a Holder in respect of the Interest Obligation will not be affected by whether or not the Corporation elects to satisfy the Interest Obligation pursuant to a Common Share Interest Payment Election.

This Debenture is one of the 9.5% Convertible Secured Debentures due 2016 (the “Debentures”) in the aggregate principal amount of up to $225 million dollars ($225,000,000) in lawful Canadian money plus up to $10.75 million dollars ($10,750,000) in lawful Canadian money plus the aggregate principal amount of Debentures in lawful Canadian money issued pursuant to the New Rights Offering (as defined in the Plan) issued under a Trust Indenture (the “Principal Indenture”) dated as of •, 2006, as supplemented by a Second Supplemental Indenture dated as of •, 2006, providing for the creation of the Debentures (the “Supplemental Indenture” and, together with the Principal Indenture, the “Indenture”), the Indenture being made between the Corporation and BNY Trust Company of Canada, as Canadian trustee (the “Canadian Trustee”) and The Bank of New York, as U.S. Trustee (together with the Canadian Trustee, the “Trustee”). Reference is hereby made to the Indenture for a description of the rights of the Holders of the Debentures, the Corporation and the Trustee and of the terms and conditions upon which the Debentures are issued and held, all to the same effect as if the provisions of the Indenture were herein set forth, to all of which provisions the Holder of this Debenture, by acceptance hereof, agrees. To the extent that the terms and conditions stated in this Debenture conflict with the terms and conditions of the Indenture, the latter prevails. All capitalized terms used herein have the meaning ascribed thereto in the Indenture unless otherwise indicated.

The Debentures are issuable as fully registered Debentures in denominations of $1,000 and integral multiples of $1,000. The Debentures of any authorized denomination may be exchanged, as provided in the Indenture, for Debentures in equal aggregate principal amount.

This Debenture and all other Debentures certified and issued under the Indenture rank pari passu with one another and all Senior Debt, in accordance to their tenor without discrimination, preference or priority. The Indenture does not contain any financial covenants or restrictions on the Corporation’s ability to pay dividends, incur additional Senior Debt or issue or repurchase securities.

- 46 -

The Corporation may, at its option but subject to regulatory approval, upon not less than 40 days and not more than 60 days prior notice, elect to satisfy its obligation to repay the principal amount of the outstanding Debentures at maturity or upon redemption or upon repurchase in the event of a Change of Control by delivery of, for each $1,000 principal amount of the Debentures, that number of Common Shares equal to the number obtained by dividing such principal amount of the Debentures by 95% of the Current Market Price of the Common Shares on the Maturity Date or the Redemption Date, provided that no Event of Default has occurred and is continuing. No fractional Common Shares will be delivered to the holders of Debentures upon such share repayment, but in lieu thereof, the Corporation will make an equivalent payment.

Each $1,000 principal amount of Debentures is convertible at any time and from time to time prior to the close of business on the Business Day immediately preceding maturity, or, if called for redemption or repurchase, the Business Day immediately preceding the date specified for redemption or repurchase of the Debentures, at the option of the Holder, into that number of Common Shares obtained by dividing $1,000 by the conversion price of $13.50 per share, subject to adjustment upon the occurrence of certain events specified in the Indenture. The Holder of a Debenture surrendered for conversion will be entitled to receive accrued and unpaid interest in respect thereof for the period up to but not including the date of conversion from the date of the latest Interest Payment Date. No fractional Common Shares will be delivered to the holders of Debentures upon conversion, but in lieu thereof, the Corporation will make an equivalent payment.

Upon the giving of notice by the Trustee of the occurrence of an Event of Default in accordance with the Indenture, the Debentures will become immediately due and payable.

At any time on and after •, 2011 and prior to •, 2013, upon at least 30 days’ prior notice, the Corporation has the right to redeem the Debentures in whole at any time or in part from time to time, for cash, at a price equal to the principal amount of the Debentures to be redeemed plus accrued and unpaid interest, if any, to but not including the date of redemption (the “Redemption Amount”) provided that the VWAP of the Common Shares on a Recognized Stock Exchange for at least 20 Trading Days in any consecutive 30 day period ending five Trading Days prior to the date on which the notice of redemption is given exceeds 125% of the Conversion Price. On and after •, 2013, the Debentures will be redeemable by the Corporation, in whole or from time to time in part, at a price equal to the principal amount of the Debentures to be redeemed plus accrued and unpaid interest, if any, to but not including the date of redemption.

The Corporation must commence, within 45 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Debentures then outstanding, at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest (if any) to but not including the Payment Date. Prior to the mailing of the notice to Holders commencing such Offer to Purchase, but in any event within 45 days following any Change of Control, the Corporation will (i) repay in full all indebtedness of the Corporation that would prohibit the repurchase of the Debentures pursuant to such Offer to Purchase, or (ii) obtain any requisite consents under instruments governing any such indebtedness of the Corporation to permit the repurchase of the Debentures. The Corporation will first comply with the provisions of the

- 47 -

immediately preceding sentence before it will be required to repurchase Debentures upon the occurrence of a Change of Control.

The Corporation may purchase Debentures in the open market or by tender or private contract at any price, that is agreed upon between the Corporation and the applicable Holders. Debentures purchased or redeemed by the Corporation will be cancelled and will not be reissued.

In all cases, if Taxes are required to be deducted or withheld from a payment in cash payable to a Holder or from Common Shares to be delivered to a Holder (including, without limitation, Common Shares issued as a result of the conversion of a Debenture at the option of the Holder, as a result of the redemption of a Debenture before maturity at the option of the Corporation or as a result of a repurchase of a Debenture following a Change of Control), such Holder will receive such payment less all such applicable Taxes.

Any payments made by or on behalf of the Corporation under or with respect to the Debentures will be made free and clear of and without withholding or deduction for or on account of any Taxes, unless the Corporation or any other payor is required to withhold or deduct Taxes by Applicable Law or by the interpretation or administration thereof by the relevant Governmental Authority. If the Corporation is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Debentures, the Corporation will make such withholding or deduction and will remit the full amount withheld or deducted to the relevant Governmental Authority as and when required by Applicable Law.

Subject to receiving applicable regulatory approvals, the Corporation will have the right to elect, from time to time, to issue and deliver Common Shares to the Trustee to raise funds in order to satisfy its Interest Obligation. Unless an Event of Default has occurred and is continuing, upon such election by the Corporation, the Trustee will have the power, on behalf of the Corporation, to (i) accept delivery of Common Shares from the Corporation, (ii) accept bids with respect to, and consummate sales of, such Common Shares, each as the Corporation directs in its absolute discretion, (iii) invest the proceeds of such sales on behalf of and for the account of the Corporation in short-term Canadian Government Obligations that mature prior to an applicable Interest Payment Date or use such proceeds to satisfy the Interest Obligation in whole or in part in respect of which the Common Share Interest Payment Election was made or both and (iv) perform any other action necessarily incidental thereto.
