The Debentures may have notations, legends or endorsements required by law, stock exchange, automated quotation system or depository rule or regulation or usage.

Each Certificate Debenture or Global Debenture, as the case may be, shall be dated the date of its authentication.

(b) Each Certificate Debenture or Global Debenture, as the case may be, shall represent such of the outstanding Debentures as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Debentures from time to time endorsed thereon and that the aggregate amount of outstanding Debentures represented thereby may from time to time be reduced or increased, as appropriate, to reflect replacements, exchanges, purchases, redemptions or conversions of such Debentures. Any adjustment of the aggregate principal amount of a Debenture to reflect the amount of any increase or decrease in the amount of outstanding Debentures represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof in accordance with this Indenture and shall be made on the records of the Registrar and the Depository, subject to (i) compliance with Applicable Procedures, if applicable, and (ii) the Trustee receiving all documentation required by the terms of this Indenture and any other documents reasonably requested by the Trustee.

(c) Prior to the completion of the Offering and the Private Placement, the Debentures shall be issued initially in the form of one or more registered and definitive Restricted Debentures, which shall be delivered to the Selling Debentureholder, as the initial Holder, or as otherwise directed thereby, and registered in the name of the Selling Debentureholder (or any successor thereto or as otherwise directed thereby), duly executed by the Corporation and authenticated by the Trustee as hereinafter provided. In the event that the Corporation determines to change a registered and definitive Certificated Debenture into a Global Debenture, such change shall be made pursuant to Applicable Procedures.

2.2 Global Debentures Generally

(a) Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global Debenture held on their behalf by the Depository or under the Global Debenture, and the Depository (including, for this purpose, its nominee) may be treated by the Corporation, the Trustee and any agent of the Corporation or the Trustee as the absolute owner and Holder of any Global Debenture for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (i) prevent the Corporation, the Trustee or any agent of the Corporation or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or (ii) impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Debenture.

(b) Each Global Debenture authenticated under this Indenture shall be registered in the name of the Depository or a nominee thereof and delivered to such Depository or a nominee thereof or custodian therefor, and each such Global Debenture shall constitute a single Debenture for purposes of this Indenture.

(c) Notwithstanding any other provisions of this Indenture or the Debentures, a Global Debenture shall not be exchanged in whole or in part for a Certified Debenture, and no Transfer of a Global Debenture in whole or in part shall be registered in the name of any Person other than the Depository or a nominee or any successor thereof; provided that a Global Debenture may be exchanged for Debentures registered in the names of any person designated by the Depository in the event that: (i) the Depository has notified the Corporation that it is unwilling or unable to continue as Depository for such Global Debentures; (ii) such Depository has ceased to be a clearing agency or otherwise ceases to be eligible to be a depository, and a successor Depository is not appointed by the Corporation within 90 days after receiving such notice or becoming aware that the Depository has ceased to be a clearing agency or otherwise ceases to be eligible to be a depository; (iii) the Corporation has determined, in its sole discretion, to terminate the book based registration system in respect of such Global Debenture and has communicated such determination to the Trustee in writing; or (iv) an Event of Default has occurred and is continuing with respect to the Debentures, provided that Agent Members acting on behalf Beneficial Owners holding more than 25% of the aggregate principal amount of the Debentures then outstanding advise the Depository in writing that the continuation of a book based registration system through the Depository is no longer in their best interest and provided further that the Trustee has not waived such Event of Default in accordance with the terms of this Indenture. Any Global Debenture exchanged pursuant to subclause (i), (ii) or (iii) of this Section 2.2(c) shall be so exchanged in whole and not in part, and any Global Debenture exchanged pursuant to subclause (iv) of this Section 2.2(c) may be exchanged in whole or from time to time in part as directed by the Depository. Any Debentures issued in exchange for a Global Debenture or any portion thereof shall be a Global Debenture; provided however that any such Debenture so issued that is registered in the name of a Person other than the Depository or a nominee or any successor thereof shall not be a Global Debenture.

(d) Debentures issued in exchange for a Global Debenture or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Debenture or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depository shall designate and shall bear the applicable legends provided for herein. Any Global Debenture to be exchanged in whole shall be surrendered by the Depository to the Trustee, as Registrar. With regard to any Global Debenture to be exchanged in part, the principal amount thereof shall be reduced by an amount equal to the portion thereof to be so exchanged, by means of a notation made on the Global Debenture as authenticated by the Trustee and an appropriate adjustment made on the records of the Depository and the Trustee.

(e) Subject to Section 2.2(g), the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Debentures.

(f) In the event of the occurrence of any of the events specified in Section 2.2(c), the Corporation will promptly make available to the Trustee a reasonable supply of Certificated Debentures in definitive, fully registered form, without interest coupons.

(g) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Debentures registered in the name of the Depository or any nominee thereof, or under any such Global Debentures, and the Depository or such nominee, as the case may be, may be treated by the Corporation, the Trustee and any Agent as the absolute owner and holder of such Global Debentures for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Corporation, the Trustee or any Agent from giving effect to any written certification, proxy or other authorization furnished by the Depository or such nominee, as the case may be, or impair, as between the Depository, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Debentures.

(h) At such time as all interests in a Global Debenture have been redeemed, converted, cancelled or exchanged for Certificated Debentures, such Global Debenture shall, upon receipt thereof, be cancelled by the Trustee in accordance with Applicable Procedures and instructions existing between the Depository and the Trustee, subject to Section 2.19 of this Indenture. At any time prior to such cancellation, if any interest in a Global Debenture is redeemed, converted, cancelled or exchanged for Certificated Debentures, the principal amount of such Global Debenture shall, in accordance with the Applicable Procedures and instructions existing between the Depository and the Trustee, be appropriately reduced by means of a notation made on the Global Debenture as authenticated by the Trustee and an appropriate adjustment made on the records of the Depository and the Trustee.

2.3 Book Entry Provisions

(a) Any Global Debenture that shall be registered in the name of the Depository or its nominee shall be executed by the Corporation and authenticated and delivered by the Trustee to the Depository or pursuant to the Depository’s instructions and shall bear legends substantially to the following effect:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO FORTIS INC. (THE “ISSUER”) OR ITS AGENT 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 A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE.”

The Fortis Order shall specify the principal amount of Debentures to be authenticated, shall provide that all such Debentures will, on an aggregate basis, initially be represented by one or more registered and definitive Restricted Debentures in accordance with Section 2.1(c), and shall further specify the principal amount of Debentures to be initially represented by the registered and definitive Restricted Debentures and the date on which the issue of Debentures is to be authenticated. Restricted Debentures representing Debentures sold in the Offering will be replaced by Unrestricted Certificated Debentures on completion of the Offering in accordance with Sections 2.1(d) and 2.14, however, Restricted Debentures representing Debentures sold in the Private Placement will continue to be represented by Restricted Debentures on completion of the Private Placement in accordance with Sections 2.1(e) and 2.14.

(b) Where Debentures are registered in more than one name, the principal, interest and premium, if any, from time to time payable in respect thereof may be paid to the order of all such Holders, failing written instructions from them to the contrary, and the receipt of any one of such Holders therefor shall be a valid discharge, to the Trustee and to the Corporation.

(c) In the case of the death of one or more joint holders of any Debentures the principal, interest and premium, if any, from time to time payable thereon may be paid to the order of the survivor or survivors of such registered holders and the receipt of any such survivor or survivors therefor shall be a valid discharge to the Trustee and to the Corporation.

Upon doing so, the Paying Agent (other than the Corporation) shall have no further liability for the money.

2.14 Transfer and Exchange

(a) Subject to compliance with any applicable additional requirements contained in Section 2.20, when a Debenture is presented to a Registrar with a request to register a transfer thereof or to exchange such Debenture for an equal principal amount of Debentures of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Debenture presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and completed in a manner satisfactory to the Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing.

(b) If any such mutilated, destroyed, lost or stolen Debenture has become or is about to become due and payable, or is about to be purchased or redeemed by the Corporation pursuant to Article 4, or converted pursuant to Article 5, the Corporation in its discretion may, instead of issuing a new Debenture, pay, redeem, purchase or convert such Debenture, as the case may be.

(c) Upon the issuance of any new Debentures under this Section 2.15, the Corporation may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith.

(d) Every new Debenture issued pursuant to this Section 2.15 in lieu of any mutilated, destroyed, lost or stolen Debenture shall constitute an original contractual obligation of the Corporation, whether or not the mutilated, destroyed, lost or stolen Debenture shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Debentures duly issued hereunder.

(e) The provisions of this Section 2.15 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures.

2.16 Outstanding Debentures

(a) Debentures outstanding at any time are all Debentures authenticated by the Trustee, except for those cancelled by it, those redeemed or purchased pursuant to Article 4, those converted pursuant to Article 5, those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those described in this Section 2.16 as not outstanding.

(b) If a Debenture is replaced pursuant to Section 2.15, it ceases to be outstanding.

(d) Any Debentures issued pursuant to this Indenture shall be cancelled by the Trustee upon their purchase by the Corporation, redemption or conversion.

Debentures so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Debentures and that the pledgee is not the Corporation or any other obligor on the Debentures or any Affiliate of the Corporation (other than Debentures owned by or behalf of the Selling Debentureholder) or of such other obligor.

Until definitive Debentures are ready for delivery, the Corporation may prepare and execute, and, upon receipt of a Fortis Order, the Trustee shall authenticate and deliver, temporary Debentures. Temporary Debentures shall be substantially in the form of definitive Debentures but may have variations that the Corporation with the consent of the Trustee considers appropriate for temporary Debentures. Without unreasonable delay, the Corporation shall prepare and the Trustee shall authenticate and deliver definitive Debentures in exchange for temporary Debentures.

All Debentures which are redeemed, purchased or otherwise acquired by the Corporation or any of its Subsidiaries prior to the Maturity Date pursuant to Article 4 shall be delivered to the Trustee for cancellation, and the Corporation may not hold or resell such Debentures or issue any new Debentures to replace any such Debentures or any Debentures that any Holder has converted pursuant to Article 5.

(a) A Global Debenture may not be Transferred, in whole or in part, to any Person other than the Depository or a nominee or any successor thereof, and no such Transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any Transfer of a Debenture that is issued in exchange for a Global Debenture but is not itself a Global Debenture. No Transfer of a Debenture to any Person shall be effective under this Indenture or the Debentures unless and until such Debenture has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Debentures, Transfers of a Global Debenture, in whole or in part, shall be made only in accordance with this Section 2.20 and, for greater certainty, Section 2.2(c).

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE [insert date that is four months and a day after the distribution date].

(b) Upon the Transfer, exchange or replacement of a Debenture bearing the Restrictive Legend, the Registrar shall deliver only a Debenture that bears the Restrictive Legend, unless (i) such Debenture has been sold pursuant to an effective prospectus under Applicable Securities Legislation or (ii) four months and a day have elapsed since the

distribution date, in each case upon receipt by the Registrar of evidence in form and substance satisfactory to it to such effect.

2.22 Restricted Legend on Common Share Certificates

The Corporation will promptly notify the Trustee of any change in the CUSIP and/ or ISIN numbers.

Article 3
INTEREST

3.1 Computation of Interest

Subject to Section 3.4(a), interest on the Debentures shall be computed by the Corporation quarterly, provided that interest for any period shorter than a full quarterly period shall be computed on the basis of a 365-day year.

3.2 Interest Act (Canada)

For purposes only of disclosure under the Interest Act (Canada), any rate of interest which is calculated with reference to a period (the “Deemed Interest Period”) that is less than the actual number of days in the calendar year of calculation is, for the purposes of the Interest Act (Canada), equivalent to an annual rate based on a calendar year calculated by multiplying such rate by the actual number of days in the calendar year in which the Deemed Interest Period ends and dividing by the number of days in the Deemed Interest Period.

3.3 Concerning Interest

Every Debenture issued hereunder, whether issued originally or in exchange for a previously issued Debenture, shall bear interest from and including the later of its Original Issue Date (or from such other date as may be expressed in such Debenture) and the last Interest Payment Date to which full interest shall have been paid or made available for payment on the outstanding Debentures. Whenever in this Indenture there is mention, in any context, of the payment of interest, such mention shall be deemed to include the payment of interest on amounts in default.

3.4 Interest Payable

(a) Subject to Section 3.7, the Debentures shall bear interest to and including the Final Instalment Date at the rate of 4% per annum payable quarterly in arrears in equal instalments on each Interest Payment Date, such interest to be payable after as well as before the Final Instalment Date and after as well as before default and judgment, with interest on amounts in default payable at the same rate, provided that the initial interest payment for the period from and including the Original Issue Date to but excluding March 1, 2014 shall be equal to $5.5890 per $1,000 principal amount of Debentures. On the day following the Final Instalment Date, the interest rate payable on the Debentures shall be 0% and interest will cease to accrue on the Debentures.

(b) Interest for each period in respect of which interest is payable under this Indenture shall be payable from and including the prior Interest Payment Date to but excluding the next following Interest Payment Date, Redemption Date or Mandatory Redemption Date, as applicable, provided that if the next following Interest Payment Date is the Final Instalment Date interest will be payable to and including the Final Instalment Date.

3.5 Deposit of Interest

Prior to 11:00 a.m., Toronto time, three Business Days preceding each Interest Payment Date under this Indenture, the Corporation shall deposit with the Paying Agent (or if the Corporation acts as Paying Agent, shall segregate and hold in trust) a sum in immediately available funds sufficient to pay such interest so becoming due on the applicable Interest Payment Date. Any such amount shall be held in trust for the benefit of Holders by the Paying Agent pursuant to Section 2.13. The Paying Agent shall as promptly as practicable return to the Corporation any funds not required for that purpose or, if such funds are then held by the Corporation in trust and are not required for such purpose, they shall be discharged from the trust.

3.6 Payment of Interest

Subject to Section 3.5, the following provisions shall apply to Debentures, except as otherwise permitted by this Indenture:

(a) As interest becomes due on each Debenture, the Corporation, either directly or through the Trustee or any agent of the Trustee, shall send or forward by prepaid ordinary mail, electronic transfer of funds or such other means as may be agreed to by the Trustee, payment of such interest (less any Withholding Taxes required or permitted to be withheld therefrom) to the order of the Holder of such Debenture appearing on the securities register maintained by the Registrar on the applicable Regular Record Date (subject to Section 5.2(b)) and addressed to the Holder at the Holder’s last address appearing on the securities register, unless such Holder otherwise directs (in any manner so directed). If payment is made by cheque, such cheque shall be forwarded at least three days prior to each date on which interest becomes due and if payment is made by other means (such as electronic transfer of funds), such payment shall be made in a manner whereby the Holder receives credit for such payment on the date such interest on such Debentures becomes due. The mailing of such cheque or the making of such payment by other means shall, to the extent of the sum represented thereby, plus the amount of any Withholding Tax withheld as aforesaid, satisfy and discharge all liability for interest on such Debentures, unless in the case of payment by cheque, such cheque is not paid at par on presentation. In the event of non-receipt of any cheque for or other payment of interest by the person to whom it is so sent as aforesaid, the Corporation or the Trustee will issue to such person a replacement cheque or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on each Debenture in the manner provided above, the Corporation may make payment of such interest or make such interest available for payment (less any Withholding Taxes required or permitted to be withheld therefrom) in any other manner acceptable to the Trustee with the same effect as though payment had been made in the manner provided above.

(b) Notwithstanding Section 3.6(a), if a Debenture is a Global Debenture, then all payments of interest on the Global Debenture shall be made by electronic funds transfer to the Depository or its nominee for subsequent payment (less applicable Withholding Taxes, if any) to Beneficial Owners of interests in the applicable Global Debenture, unless the Corporation and the Depository otherwise agree. None of the Corporation, the Trustee or any agent of the Trustee for any Debenture issued as a Global Debenture will be liable or responsible to any person for any aspect of the records related to or payments made on account of beneficial interests in any Global Debenture or for maintaining, reviewing, or supervising any records relating to such beneficial interests.

3.7 Make-Whole Payment

If the Final Instalment Date occurs prior to the first anniversary of the date of this Indenture, the Corporation shall pay on the Business Day following the Final Instalment Date, the Make-Whole Payment to Holders of record on the Final Instalment Date who have paid the Final Instalment on or before the Final Instalment Date. For greater certainty, no Make-Whole Payment will be payable if the Final Instalment Date occurs on or after the first anniversary of the date of this Indenture.

3.8 Deposit of Make-Whole Payment

Prior to 11:00 a.m., Toronto time, on the Final Instalment Date the Corporation shall deposit with the Trustee (or, if the Corporation acts as Paying Agent, shall segregate and hold in trust) a sum in immediately available funds sufficient to pay the Make-Whole Payment due and payable on the Business Day following the Final Instalment Date, if applicable. Any such amount shall be held in trust for the benefit of Holders by the Paying Agent pursuant to Section 2.13. The Payment Agent shall as promptly as practicable return to the Corporation any funds not required for that purpose or, if such funds are then held by the Corporation in trust and are not required for such purpose, they shall be discharged from the trust.

Article 4
REDEMPTION AND PURCHASE

4.1 Redemption

(a) The Debentures are not redeemable by the Corporation except (i) as described under Section 4.5, and (ii) on or after the Final Instalment Date and before the Maturity Date, subject to receipt of any required regulatory approval, the Corporation shall have the right at its option to redeem the Debentures issued hereunder, either in whole or in part, at the Redemption Price in accordance with the terms and conditions of this Indenture, the Debentures or a supplemental indenture authorizing or providing for the issue thereof.

(b) If less than all the Debentures for the time being outstanding are at any time to be redeemed pursuant to Section 4.1(a), the Debentures to be so redeemed shall be selected by the Trustee on a pro rata basis to the nearest multiple of $1,000 in accordance with the principal amount of the Debentures registered in the name of each Holder or in such other manner as the Trustee deems equitable, subject to the receipt of any required regulatory approval. Unless otherwise specifically provided in the terms of any series of Debentures, no Debentures shall be redeemed in part unless the principal amount redeemed is $1,000 or a multiple thereof. In the event that one or more of such Debentures becomes subject to redemption in part only, upon surrender of any such Debentures for payment of the Redemption Price, the Corporation shall execute and the Trustee shall authenticate and deliver without charge to the Holder thereof or upon the Holder’s order one or more new Debentures for the unredeemed part of the principal amount of the Debentures so surrendered or, with respect to a Global Debenture, the principal amount thereof shall be reduced by an amount equal to the portion thereof to be so exchanged,

by means of a notation made on the Global Debenture as authenticated by the Trustee and an appropriate adjustment made on the records of the Depository and Trustee.

4.2 Redemption Notice

(a) Except in the event of a mandatory redemption pursuant to Section 4.5, at least 15 days but not more than 30 days before a Redemption Date, the Corporation shall mail or cause to be mailed a notice of redemption to each Holder of Debentures to be redeemed (and to Beneficial Owners as required by applicable law) determined on a date being not more than 10 days before the date on which such notice is sent (the “Redemption Notice”). A Redemption Notice shall be mailed to the address of each such Holder as such address appears on the Registrar’s books.

(b) The Redemption Notice shall identify the Debentures (including CUSIP numbers) to be redeemed and shall state:

(i)	the Redemption Date;

(ii)	the Redemption Price;

(iii)	the then effective Conversion Rate and Conversion Price;

(iv)	the name and address of the Trustee;

(v)	that Debentures called for redemption must be presented and surrendered to the Trustee to collect the Redemption Price; and

(vi)	that Holders who wish to convert Debentures prior to redemption must surrender such Debentures for conversion no later than the close of business on the Business Day immediately preceding the Redemption Date and must satisfy the other requirements set forth in Article 5.

(c) If any of the Debentures to be redeemed is in the form of a Global Debenture, then the Corporation shall modify the Redemption Notice to the extent necessary to accord with the Applicable Procedures of the Depository applicable to redemptions. At the Corporation’s written request, which request shall (i) be irrevocable once given and (ii) set forth all relevant information required by clauses (i) through (vi) of Section 4.2(b), the Trustee shall give the Redemption Notice to each Holder in the Corporation’s name and at the Corporation’s expense; provided, however, that in all cases, the text of such Redemption Notice shall be prepared by the Corporation; and provided further that if such Redemption Notice is to be mailed by the Trustee such request must be given to the Trustee at least five Business Days (or such lesser number of days as the Trustee may accept) prior to the date by which such Redemption Notice must be mailed to the Holders in accordance with this Section 4.2.

4.3 Effect of a Redemption Notice

Upon delivery of a Redemption Notice, Holders shall thereafter be entitled to receive the Redemption Price with respect to their respective Debentures on the Redemption Date. Such Redemption Price shall be paid to such Holder promptly following the later of (i) the Redemption Date (provided that the conditions in Section 4.4 have been satisfied) and (ii) the time of delivery of such Debenture to and actual receipt by the Trustee from the Holder thereof in the manner required by this Indenture.

4.4 Deposit of Redemption Price

(a) Prior to 11:00 a.m., Toronto time, on the Business Day immediately preceding the Redemption Date, the Corporation shall deposit with the Paying Agent (or, if the Corporation acts as Paying Agent, shall segregate and hold in trust) an amount of money in immediately available funds sufficient to pay the Redemption Price payable upon redemption on all Debentures to be redeemed on that date, other than Debentures or portions thereof called for redemption on that date which have been delivered by the Corporation to the Trustee for cancellation or have been converted as permitted hereunder. Any such amount shall be held in trust for the benefit of Holders by the Paying Agent pursuant to Section 2.13. The Paying Agent shall as promptly as practicable return to the Corporation any funds not required for that purpose or, if such funds are then held by the Corporation in trust and are not required for such purpose, they shall be discharged from the trust.

(b) If the Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Redemption Price of any Debenture for which a Redemption Notice has been tendered in accordance with this Indenture then, on the Redemption Date, such Debenture will cease to be outstanding, whether or not the Debenture is delivered to the Trustee, and interest shall cease to accrue, and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Redemption Price as aforesaid).

4.5 Mandatory Redemption

(a) If a Mandatory Redemption Event occurs the Debentures shall be redeemed by the Corporation at the Redemption Price as soon as practicable after the date of the Mandatory Redemption Event as fixed in the Mandatory Redemption Event Notice delivered pursuant to Section 4.5(b) (the “Mandatory Redemption Date”). Subject to Section 4.8, the Mandatory Redemption Date may, with the consent of the Trustee, be as early as the first Business Day after the day on which the Mandatory Redemption Event Notice is given, and, in any event, shall be as soon as practicable following the date of the Mandatory Redemption Notice.

(b) Subject to Section 4.8, on the occurrence of a Mandatory Redemption Event the Corporation shall as soon as practical thereafter issue a press release and deliver a written notice of the Mandatory Redemption Event to the Trustee and to each Holder (and to Beneficial Owners as required by applicable law) determined on a date being not more than 10 days before the date on which such notice is sent (a “Mandatory Redemption Event Notice”). A

Mandatory Redemption Event Notice shall be mailed to the address of each such Holder as such address appears on the Registrar’s books. A Mandatory Redemption Event Notice shall state:

(i)	that a Mandatory Redemption Event has occurred under the Indenture and provide a description of the Mandatory Redemption Event which has occurred, including the date on which the Mandatory Redemption Event occurred;

(ii)	the Mandatory Redemption Date;

(iii)	notify Holders that all Debentures shall be redeemed by the Corporation as of the Mandatory Redemption Date;

(iv)	that, unless the Corporation fails to pay the Redemption Price pursuant to the Indenture, the Debentures will cease to be outstanding and interest will cease to accrue on the Mandatory Redemption Date;

(v)	that any Final Instalment Notice previously delivered under the Instalment Receipt Agreement and any Final Instalment Date set out therein are deemed to be revoked and of no further force and effect;

(vi)	the name and address of the Trustee;

(vii)	that Debentures called for redemption must be presented and surrendered to the Trustee to collect the Redemption Price; and

(viii)	the CUSIP and/or ISIN number of the Debentures.

(c) If any of the Debentures to be redeemed is in the form of a Global Debenture, then the Corporation shall modify the Redemption Notice to the extent necessary to accord with the Applicable Procedures of the Depository applicable to redemptions. At the Corporation’s written request, which request shall (i) be irrevocable once given and (ii) set forth all relevant information required by clauses (b)(i)(i) through (viii) of Section 4.5(b) the Trustee shall give such Mandatory Redemption Event Notice in the Corporation’s name and at the Corporation’s expense; provided, that, in all cases, the text of such Mandatory Redemption Event Notice shall be prepared by the Corporation; and provided further that if such Mandatory Redemption Event Notice is to be mailed by the Trustee, such request must be given to the Trustee at least five Business Days (or such lesser number of days as the Trustee may accept) prior to the date on which the Mandatory Redemption Event Notice is to be mailed to the Holders in accordance with this Section 4.5.

(d) The Corporation shall deposit cash at the time and in the manner as provided in Section 4.7, sufficient to pay the aggregate Redemption Price of all Debentures redeemed pursuant to this Section 4.5.

4.6 Effect of Mandatory Redemption Event Notice

Upon delivery of a Mandatory Redemption Event Notice, Holders shall thereafter be entitled to receive the Redemption Price with respect to their respective Debentures on the Mandatory Redemption Date. Such Redemption Price shall be paid to such Holder promptly following the later of (i) the Mandatory Redemption Date (provided that the conditions in Section 4.7 have been satisfied) and (ii) the time of delivery of such Debenture to and actual receipt by the Trustee from the Holder thereof in the manner required by this Indenture.

4.7 Deposit of Redemption Price

(a) On or before 11:00 a.m., Toronto time, on the Business Day preceding the applicable Mandatory Redemption Date, the Corporation shall deposit with the Paying Agent (or if the Corporation or an Affiliate of the Corporation is acting as the Paying Agent, shall segregate and hold in trust) an amount of money in immediately available funds sufficient to pay the aggregate Redemption Price of all the Debentures. Any such amount shall be held in trust for the benefit of Holders by the Paying Agent pursuant to Section 2.13.

(b) If the Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Redemption Price of the Debentures then, on the applicable Mandatory Redemption Date, each Debenture will cease to be outstanding, whether or not the Debenture is delivered to the Trustee, and interest shall cease to accrue, and the rights of the Holder in respect of the Debenture shall terminate (other than the right to receive the Redemption Price as aforesaid).

(c) If a Mandatory Redemption Date falls after a Regular Record Date and on or before the related Interest Payment Date, then interest on the Debentures payable on such Interest Payment Date (which, for greater certainty, shall be payable only for the period to and including the Mandatory Redemption Date) will instead be payable on the Mandatory Redemption Date to the Holders in whose names the Debentures are registered at the close of business on such Regular Record Date.

4.8 Notice to TSX

If the Instalment Receipts are listed and posted for trading on the TSX on the date of a Mandatory Redemption Event the Corporation shall provide at least 15 days prior written notice of the Mandatory Redemption Date to the TSX.

4.9 Repayment to the Corporation

To the extent that the aggregate amount of cash deposited by the Corporation pursuant to Section 4.7 exceeds the aggregate Redemption Price of the Debentures then promptly after the Mandatory Redemption Date the Paying Agent shall return any such excess cash to the Corporation or, if such funds are then held by the Corporation in trust and are not required for such purpose, they shall be discharged from the trust.

4.10 Right to Pay Principal Amount of the Debentures in Common Shares

(a) Subject to the other provisions of this Section 4.10, the Corporation may, at its option, elect to satisfy its obligation to pay all or any portion of the principal amount of the Debentures on maturity by issuing and delivering to Holders on the Maturity Date that number of Common Shares obtained by dividing the aggregate principal amount of the Debentures then outstanding by 95% of the Market Price (the “Share Maturity Right”).

(b) The Corporation shall exercise the Share Maturity Right in its sole discretion and need not provide notice of such determination to Holders.

(c) The Corporation’s right to exercise the Share Maturity Right shall be conditional upon the following conditions being met on the Business Day immediately preceding the Maturity Date:

(i) the Common Shares to be issued on exercise of the Share Maturity Right shall be qualified for distribution under Applicable Securities Legislation;

(ii) the Common Shares to be issued on exercise of the Share Maturity Right shall be listed on the TSX or a United States national securities exchange or quoted in an interdealer quotation system of any United States registered national securities association;

(iii) the Corporation shall be a reporting issuer in Canada not in default of its reporting obligations under Applicable Securities Legislation where the distribution of such Common Shares occurs;

(iv) no Event of Default shall have occurred and be continuing;

(v) the receipt by the Trustee of an Officers’ Certificate stating that the conditions in Sections 4.10(c)(i), 4.10(c)(ii), 4.10(c)(iii) and 4.10(c)(iv) have been satisfied and setting forth the number of Common Shares to be issued and delivered on exercise of the Share Maturity Right and the Market Price used for calculating the number of Common Shares to be issued and delivered to Holders on exercise of the Share Maturity Right; and

(vi) 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 Indenture in payment (whether in whole or in part) of the aggregate principal amount of the Debentures then outstanding will be validly issued as fully paid and non-assessable and that the conditions in Sections 4.10(c)(i) and 4.10(c)(ii) have been satisfied.

If the foregoing conditions are not satisfied prior to the close of business on the Business Day preceding the Maturity Date, the Corporation shall pay the aggregate principal amount of the

Debentures in cash in accordance with Sections 2.12 and 7.1 and paragraph 3 of the Debentures unless each of the Holders and the Corporation waives the conditions which are not satisfied.

(d) In the event that the Corporation duly exercises its Share Maturity Right, the Corporation shall, on or before 11:00 a.m. Toronto Time on the Business Day immediately preceding the Maturity Date, make delivery to the Trustee for delivery to and on account of the Holders, of certificates representing the Common Shares to which such Holders are entitled or otherwise make or direct electronic delivery thereof in accordance with Applicable Procedures.

(e) The Corporation will not issue fractional Common Shares upon the exercise of the Share Maturity Right. If more than one Debenture shall be surrendered for purchase at one time by the same Holder, the number of full Common Shares that shall be issuable upon purchase shall be computed on the basis set forth in Section 4.10(a). In lieu of any fractional Common Shares, the Corporation will pay to the Trustee for the account of the Holders, at the time contemplated in Section 7.1 and paragraph 3 of the Debentures, the cash equivalent thereof (less any Withholding Tax required to be deducted, if any) determined for each Holder by multiplying the applicable fraction of a Share otherwise to be issued and delivered under this Section 4.10 by 95% of the Market Price; provided however, that the Corporation shall not be required to make any payment of less than $10.00.

(f) A Holder shall be treated as the Holder of record of the Common Shares issued on due exercise by the Corporation of its Share Maturity Right effective immediately after the close of business on the Maturity Date, and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including dividends or distributions in kind) thereon and arising thereafter, and in the event that the Trustee receives the same, it shall hold the same for the benefit of such Holder.

(g) The Corporation shall at all times reserve and keep available out of its authorized Common Shares (if the number thereof is or becomes limited), solely for the purpose of issue and delivery upon the exercise of the Share Maturity Right as provided herein, and shall issue to Holders to whom Common Shares will be issued pursuant to the exercise of the Share Maturity Right, such number of Common Shares as shall be issuable in such event. All Common Shares which shall be so issuable shall be duly and validly issued as fully paid and non-assessable.

4.11 Debentures Purchased in Part

Any Debenture that is not in the form of a Global Debenture, that is to be purchased or redeemed only in part shall be surrendered at the Corporate Trust Office and promptly after the Redemption Date, the Corporation shall execute and the Trustee shall authenticate and deliver to the Holder of such Debenture, without service charge, a new Debenture or Debentures, of such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Debenture so surrendered that is not purchased. No Debenture shall be purchased in part unless the principal amount redeemed is $1,000 or any multiple thereof. With respect to Global Debentures, in the event Debentures are redeemed only

in part, the Trustee shall make notations on the Global Debenture of the principal amount thereof so redeemed in accordance with the Applicable Procedures.

4.12 Compliance with Securities Laws Upon Purchase of Debentures

In connection with any offer to purchase Debentures under Section 4.13, the Corporation shall comply with all Canadian federal and provincial laws in connection with such offer to purchase or purchase of Debentures, all so as to permit the rights of the Holders and obligations of the Corporation under Section 4.10 to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would result in a conflict with any of the terms hereof, this Indenture is hereby modified to the extent required for the Corporation to comply with such laws, rules and regulations.

4.13 Purchase of Debentures in Open Market

The Corporation shall surrender any Debenture purchased or redeemed by the Corporation pursuant to this Article 4 to the Trustee for cancellation. Any Debentures surrendered to the Trustee for cancellation may not be reissued or resold by the Corporation and will be cancelled promptly in accordance with Section 2.19. Subject to applicable laws, the Corporation may repurchase Debentures in the open market or by issuer bid or tender at any price or by private agreement.

Article 5
CONVERSION

5.1 Conversion Right and Conversion Rate

(a) Upon compliance with the provisions of this Article 5, at the option of the Holder thereof, the Debentures of such Holder may be converted into fully paid, non-assessable and freely tradeable Common Shares (calculated as to each conversion to the nearest share) on the Final Instalment Date and at any time thereafter, but prior to the close of business on the Business Day immediately preceding the earlier of the Redemption Date or the Maturity Date, unless such Debentures have previously been redeemed or purchased for cancellation by the Corporation, at the Conversion Rate in effect at such time, determined as hereinafter provided, and subject to the adjustments contained in Sections 5.5 or 5.9.

(b) The conversion rights pursuant to this Article 5 shall commence on the Final Instalment Date and expire at the close of business on the Business Day immediately preceding the Maturity Date, subject, in the case of conversion of any Global Debenture, to any Applicable Procedures. If a Debenture is called for redemption pursuant to Section 4.2, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date for such Debenture (unless the Corporation shall fail to pay the Redemption Price when due in accordance with Section 4.4, in which case the conversion right shall terminate at the close of business on the date such failure is cured and such Debenture is redeemed).

(c) Provisions of this Indenture that apply to conversion of all of a Debenture also apply to conversion of a portion of a Debenture.

(d) A Holder of Debentures is not entitled to any rights of a holder of Common Shares until such Holder has converted its Debentures into Common Shares, and only to the extent such Debentures are deemed to have been converted into Common Shares pursuant to this Article 5.

(e) The Conversion Rate shall be adjusted in certain instances as provided in Section 5.5.

(f) By delivering the number of Common Shares issuable on conversion to the Trustee and any payment for fraction Common Shares in accordance with Section 5.3, the Corporation will be deemed to have satisfied its obligation to pay the principal amount of the Debentures so converted.

5.2 Conversion Procedure

(a) To convert a Debenture, a Holder must (i) complete and manually sign the conversion notice on the back of the Debenture and deliver such notice to the Conversion Agent, (ii) surrender the certificates representing the Debenture (if any) to the Trustee, (iii) furnish appropriate endorsements and transfer documents if required by the Trustee, and (iv) if required, pay all transfer and similar taxes. The date on which the Holder satisfies all of those requirements is the “Conversion Date”. In connection with the conversion of a Debenture, the Corporation will pay the cash, if any, representing fractional Common Shares and deliver the Common Shares, as applicable, as promptly as practicable after the later of the Conversion Date and the date that all calculations necessary to make such payment and delivery have been made, but in no event later than five Business Days after the later of those dates. Anything herein to the contrary notwithstanding, in the case of Global Debentures, conversion notices may be delivered and such Debentures may be surrendered for conversion in accordance with the Applicable Procedures.

(b) The person in whose name the Common Shares are issuable upon conversion shall be deemed to be a holder of record of such Common Shares on the Conversion Date; provided, however, that no surrender of a Debenture on any Conversion Date when the stock transfer books of the Corporation maintained by the transfer agent shall be closed shall be effective to constitute the person or persons entitled to receive the Common Shares upon conversion as the record holder or holders of such Common Shares on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such Common Shares as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided further that such conversion shall be at the Conversion Rate in effect on the Conversion Date as if the stock transfer books of the Corporation had not been closed. Upon conversion of a Debenture, such person shall no longer be a Holder of such Debenture. Except as set forth in this Indenture, no

payment or adjustment will be made for dividends or distributions declared or made on Common Shares issued upon conversion of a Debenture prior to the issuance of such Common Shares.

(c) Holders of Debentures surrendered for conversion in respect of which there is any accrued and unpaid interest or an unpaid Make-Whole Payment will receive payment of such accrued and unpaid interest and Make-Whole Payment, if applicable, together with the Common Shares issuable to such Holder pursuant to this Article 5.

(d) A Holder may exercise its right to convert the Debentures held by such Holder in accordance with this Article 5, following the issuance by the Corporation of a Notice of Redemption or Maturity Notice and prior to the close of business on the Business Day immediately preceding the Redemption Date and Maturity Date, as applicable.

5.3 Fractional Common Shares

The Corporation will not issue fractional Common Shares upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same Holder, the number of full Common Shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the extent permitted hereby) so surrendered. In lieu of any fractional Common Share, the Corporation will pay an amount in cash equal to the applicable fraction multiplied by the Conversion Price; provided, however, that the Corporation shall not be required to make any payment of less than $10.00.

5.4 Corporation to Provide Common Shares

(a) The Corporation shall, prior to issuance of any Debentures hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Shares, a sufficient number of Common Shares to permit the conversion of all outstanding Debentures into Common Shares pursuant to this Article 5.

(b) All Common Shares delivered upon conversion of the Debentures shall be newly issued Common Shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from pre-emptive or similar rights and free of any Lien or adverse claim as the result of any action by the Corporation.

(c) The Corporation will endeavour promptly to comply with all Applicable Securities Legislation and United States securities laws regulating the offer and delivery of Common Shares upon conversion of Debentures.

5.5 Adjustment of Conversion Rate

(a) Subject to Section 5.6, the Conversion Rate shall be adjusted from time to time by the Corporation as follows:

(i) If the Corporation shall pay a dividend or make a distribution to all holders of outstanding Common Shares in Common Shares, or securities convertible into Common Shares, the Conversion Rate in effect immediately preceding the record date for the determination of shareholders entitled to receive such dividend or other distribution shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately preceding such record date by a fraction of which the numerator shall be the sum of (x) the number of Common Shares outstanding at the close of business on such record date plus (y) the total number of Common Shares offered (or into which the convertible securities so offered are convertible) constituting such dividend or other distribution and of which the denominator shall be the number of Common Shares outstanding at the close of business on such record date. The Conversion Price will be correspondingly decreased if the Conversion Rate is increased pursuant to this Section 5.5(a)(i). Such adjustment shall be made successively whenever any such dividend or distribution is made and shall become effective immediately after such record date. For the purpose of this Section 5.5(a)(i), the number of Common Shares at any time outstanding shall not include Common Shares held in the treasury of the Corporation. The Corporation will not pay any dividend or make any distribution on Common Shares held in the treasury of the Corporation. If any dividend or distribution of the type described in this Section 5.5(a)(i) is declared but not so paid or made, the Conversion Rate and Conversion Price shall again be adjusted to the Conversion Rate and Conversion Price that would then be in effect if such dividend or distribution had not been declared.

(ii) If the Corporation shall subdivide its outstanding Common Shares into a greater number of Common Shares, or combine its outstanding Common Shares into a smaller number of Common Shares, the Conversion Rate in effect immediately preceding the day upon which such subdivision or combination becomes effective shall be, in the case of a subdivision of Common Shares, proportionately increased (and the Conversion Price correspondingly reduced) and, in the case of a combination of Common Shares, proportionately reduced (and the Conversion Price correspondingly increased). Such adjustment shall be made successively whenever any such subdivision or combination of the Common Shares occurs and shall become effective immediately after the date upon which such subdivision or combination becomes effective.

(iii) If the Corporation shall issue rights or warrants to all holders of its outstanding Common Shares entitling them (for a period expiring within 45 days after such issuance) to subscribe for or purchase Common Shares (or securities convertible into Common Shares) at a price per Common Share (or having a conversion price per Common Share) less than the

Conversion Price on the record date for the determination of shareholders entitled to receive such rights or warrants, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately preceding such record date by a fraction of which the numerator shall be the sum of (x) the number of Common Shares outstanding at the close of business on such record date plus (y) the number of additional Common Shares offered (or into which the convertible securities so offered are convertible) and of which the denominator shall be the sum of (x) the number of Common Shares outstanding at the close of business on such record date plus (y) the number of Common Shares which the aggregate offering price of the total number of Common Shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered for subscription or purchase, which shall be determined by multiplying the number of Common Shares issuable upon conversion of such convertible securities by the conversion price per Common Share pursuant to the terms of such convertible securities) would purchase at the Conversion Price on such record date. The Conversion Price will be correspondingly decreased if the Conversion Rate is increased pursuant to this Section 5.5(a)(iii). Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. To the extent that Common Shares (or securities convertible into Common Shares) are not delivered after the expiration of such rights or warrants, the Conversion Rate and Conversion Price shall be readjusted to the Conversion Rate and Conversion Price that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of Common Shares actually delivered. If such rights or warrants are not so issued, the Conversion Rate and Conversion Price shall again be adjusted to be the Conversion Rate and Conversion Price that would then be in effect if the record date for the determination of shareholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the shareholders to subscribe for or purchase Common Shares at a price less than the Conversion Price and in determining the aggregate offering price of the total number of Common Shares so offered, there shall be taken into account any consideration received by the Corporation for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(iv) If the Corporation shall make a distribution to all holders of Common Shares of (A) shares in the capital of the Corporation, (other than (I) Common Shares or (II) a dividend payable exclusively in cash), or (B) evidences of indebtedness or other assets of the Corporation, including

securities (the “Distributed Securities”), (but excluding any issuance of rights or warrants for which any adjustment was made pursuant to Section 5.5(a)(iii), then in each such case (unless the Corporation distributes such Distributed Securities to the Holders of Debentures on such dividend or distribution date (as if each Holder had converted such Debentures into Common Shares immediately preceding the record date with respect to such distribution)) the Conversion Rate in effect immediately preceding the record date fixed for the determination of shareholders entitled to receive such dividend or distribution shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately preceding such record date by a fraction of which the numerator shall be (x) the Conversion Price on such record date and of which the denominator shall be (y) the Conversion Price on such record date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) on such record date of the portion of the Distributed Securities so distributed applicable to one Common Share (determined on the basis of the number of Common Shares outstanding at the close of business on such record date). The Conversion Price will be correspondingly decreased if the Conversion Rate is increased pursuant to this Section 5.5(a)(iv). Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate and Conversion Price shall again be adjusted to be the Conversion Rate and Conversion Price that would then be in effect if such dividend or distribution had not been declared. For greater certainty, any adjustment to the Conversion Rate and Conversion Price pursuant to this Section 5.5(a)(iv) shall be subject to the prior approval of the TSX or such other exchange on which the Common Shares are then listed.

If the then fair market value (as so determined) of the portion of the Distributed Securities so distributed applicable to one Common Share is equal to or greater than the Conversion Price on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of a Debenture shall have the right to receive upon conversion the amount of Distributed Securities so distributed that such Holder would have received had such Holder converted each Debenture on such record date.

Notwithstanding the foregoing, if the securities distributed by the Corporation to all holders of its Common Shares consist of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the

Corporation (the “Spinoff Securities”), the Conversion Rate shall be adjusted, unless the Corporation makes an equivalent distribution to the Holders of Debentures, so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the record date fixed for the determination of shareholders entitled to receive such distribution by a fraction, the numerator of which shall be the sum of (A) the Market Price of one Common Share determined as of the date on which ex-dividend trading commences for such distribution on the TSX (the “Spinoff Valuation Period”) or such other national or regional exchange or market on which the Common Shares are then listed or quoted and (B) the product of (i) the weighted average trading price (calculated in substantially the same way as the Market Price is calculated for the Common Shares) over the Spinoff Valuation Period of the Spinoff Securities or, if no such prices are available, the fair market value of the Spinoff Securities as reasonably determined by the Board of Directors (which determination shall be conclusive and shall be evidenced by an Officers’ Certificate delivered to the Trustee) multiplied by (ii) the number of Spinoff Securities distributed in respect of one Common Share and the denominator of which shall be the Market Price of one Common Share over the Spinoff Valuation Period, such adjustment to become effective immediately preceding the opening of business on the 25th Trading Day after the date on which ex-dividend trading commences. Any such increase in the Conversion Rate shall result in a corresponding decrease in the Conversion Price.

(v) If any tender offer made by the Corporation or any of its Subsidiaries for all or any portion of Common Shares shall expire, then, if the tender offer shall require the payment to shareholders of consideration per Common Share having a fair market value (determined as provided below) that exceeds the Conversion Price on the last date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the “Expiration Time”), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately preceding the close of business on the Expiration Date by a fraction of which (i) the numerator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) payable to shareholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all Common Shares validly tendered and not withdrawn as of the Expiration Time (the Common Shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Common

Shares”) and (B) the product of the number of Common Shares outstanding (less any Purchased Common Shares and excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time and the Conversion Price on the Expiration Date and (ii) the denominator of which shall be the product of the number of Common Shares outstanding (including Purchased Common Shares but excluding any Common Shares held in the treasury of the Corporation) at the Expiration Time multiplied by the Conversion Price on the Expiration Date, such increase to become effective immediately preceding the opening of business on the day following the Expiration Date. In the event that the Corporation is obligated to purchase Common Shares pursuant to any such tender offer, but the Corporation is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of Common Shares actually purchased, if any. If the application of this Section 5.5(a)(v) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 5.5(a)(v). The Conversion Price shall be correspondingly decreased if the Conversion Price is increased pursuant to this Section 5.5(a)(v).

(vi) For purposes of this Section 5.5, the term “tender offer” shall mean and include tender offers, take-over bids, issuer bids and exchange offers, all references to “purchases” of Common Shares in tender offers (and all similar references) shall mean and include the purchase of Common Shares in tender offers and the acquisition of Common Shares pursuant to take over bids, issuer bids or exchange offers, and all references to “tendered Common Shares” (and all similar references) shall mean and include Common Shares tendered in both tender offers, take over bids, issuer bids and exchange offers.

(b) In the event of any question arising with respect to the adjustments provided in this Section 5.5, such question will be conclusively determined by a firm of nationally recognized chartered accountants appointed by the Corporation (who may be the auditors of the Corporation); such accountants will have access to all necessary records of the Corporation and such determination will be binding upon the Corporation, the Trustee, and the Holders, absent manifest error.

(c) In case the Corporation takes any action affecting the Debentures or the Common Shares other than actions described in this Section 5.5, which in the opinion of the Board of Directors, would materially affect the rights of Holders (including their conversion rights), the Conversion Rate and Conversion Price will be adjusted in such manner and at such time, by action of the Board of Directors, subject to the prior written consent of the TSX or such other exchange on which the Common Shares are then listed, as the Board of Directors in its sole

discretion may determine to be equitable in the circumstances. Failure of the Board of Directors to make such an adjustment will be conclusive evidence that they have determined that it is equitable to make no adjustment in the circumstances.

(d) In any case in which this Section 5.5 shall require that an adjustment be made following a record date or Expiration Date, as the case may be, established for the purposes specified in this Section 5.5, the Corporation may elect to defer (but only until five Business Days following the filing by the Corporation with the Trustee of the certificate described in Section 5.7) issuing to the Holder of any Debenture converted after such record date or Expiration Date the Common Shares and other Capital Stock of the Corporation issuable upon such conversion over and above the Common Shares and other Capital Stock of the Corporation (or other cash, property or securities, as applicable) issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of any cash, property or securities the issuance of which is so deferred, the Corporation shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Corporation of the right to receive such property or securities. If any distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record date or Expiration Date therefor is not thereafter made or paid by the Corporation for any reason, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such record date or Expiration Date had not occurred.

(e) For purposes of this Section 5.5, “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Shares have the right to receive any securities or other property or in which the Common Shares (or other applicable security) are exchanged or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such cash, security or other property (whether or not such date is fixed by the Board of Directors or by statute, contract or otherwise).

(f) If one or more event occurs requiring an adjustment be made to the Conversion Rate for a particular period, adjustments to the Conversion Rate shall be determined by the Corporation’s Board of Directors to reflect the combined impact of such Conversion Rate adjustment events, as set out in this Section 5.5, during such period.

5.6 No Adjustment

(a) No adjustment in the Conversion Rate shall be required if Holders may participate in the transactions set forth in Section 5.5 (to the same extent as if the Debentures had been converted into Common Shares immediately preceding such transactions) without converting the Debentures held by such Holders, subject to regulatory and TSX approval.

(b) No adjustment in the Conversion Rate or Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this Section 5.6(b) shall be carried forward and taken into account in any

subsequent adjustment. All calculations under this Article 5 shall be made to the nearest cent or to the nearest whole share, as the case may be, with one half cent and one half of a share, respectively, being rounded upward.

(c) No adjustment in the Conversion Rate shall be required for issuances of Common Shares pursuant to a Corporation plan for reinvestment of dividends or interest, including the DRIP, or for the declaration or payment of special or ordinary cash dividends by the Corporation.

5.7 Notice of Adjustment

Whenever the Conversion Rate or Conversion Price is required to be adjusted pursuant to this Indenture, the Corporation shall first promptly provide the TSX or such other exchange on which the Common Shares are then listed with written notice of the adjustment. The Corporation shall then also promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Failure to provide or mail any such notices or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate and Conversion Price, the Trustee may assume without inquiry that the Conversion Rate and Conversion Price have not been adjusted and that the last Conversion Rate and Conversion Price of which it has knowledge remains in effect.

5.8 Notice of Certain Transactions

In the event that there is a dissolution or liquidation of the Corporation, the Corporation shall mail to Holders and file with the Trustee a notice stating the proposed effective date. The Corporation shall mail such notice at least 20 days before such proposed effective date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in this Section 5.8.

5.9 Effect of Reclassification, Consolidation, Amalgamation, Merger or Sale on Conversion Privilege

(a) If any of the following shall occur, namely:

(i) any reclassification, recapitalization or other change of Common Shares issuable upon conversion of the Debentures (other than as a result of a subdivision or combination or any other transaction or event for which an adjustment is provided in Section 5.5);

(ii) any statutory share exchange, consolidation, amalgamation, arrangement, merger or other combination to which the Corporation is a party other than a merger which does not result in any reclassification of, or a change (other than as a result of a subdivision or combination) in outstanding Common Shares; or

(iii) any sale or conveyance of all or substantially all the property and assets of the Corporation, directly or indirectly, to any person (other than a directly or indirectly wholly-owned Subsidiary of the Corporation),

then the Corporation and any such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, recapitalization, change, combination, statutory share exchange, consolidation, amalgamation, arrangement, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture to this Indenture providing that the Holders be entitled to convert the Debentures with a Conversion Rate to be adjusted accordingly so that, upon the conversion of a Debenture, the Holder will be entitled to receive the Common Shares, Capital Stock or other securities and property (including cash) receivable upon such reclassification, recapitalization, change, combination, statutory share exchange, consolidation, merger, amalgamation, arrangement, sale or conveyance by a holder of the number of Common Shares deliverable upon conversion of such Debentures immediately preceding such reclassification, recapitalization, change, combination, statutory share exchange, consolidation, merger, amalgamation, arrangement, sale or conveyance (assuming such holder of Common Shares did not exercise any right of election as to the kind or amount of stock, other securities or other property or assets, including cash, receivable upon such transaction, and provided that if the kind or amount of stock, other securities or other property or assets receivable upon such transaction is not the same for each Common Share in respect of which such rights of election shall not have been exercised, then the kind and amount shall be deemed to be the kind and amount receivable per Common Share by a plurality of the non-electing Common Shares). Such supplemental indenture shall provide for adjustments of the Conversion Rate and Conversion Price and other appropriate numerical thresholds which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate and Conversion Price provided for in this Article 5. If, in the case of any such consolidation, merger, amalgamation, arrangement, combination, statutory share exchange, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Shares include Common Shares, Capital Stock or other securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, amalgamation, arrangement, combination, statutory share exchange, sale or conveyance, then such supplemental indenture shall contain such adjustments to the Conversion Rate as are necessary having regard to the value of such securities or other property deliverable to a holder of Common Shares as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 5.9 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, amalgamations, arrangements, sales or conveyances. If this Section 5.9(a) applies to any event or occurrence, Section 5.5 shall not apply.

(b) In the event the Corporation shall execute a supplemental indenture pursuant to this Section 5.9, the Corporation shall promptly file with the Trustee;

(i) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Common Shares or Capital Stock or other securities or property (including cash) receivable by Holders of the Debentures upon the

conversion of their Debentures after any such reclassification, recapitalization, change, combination, consolidation, merger, amalgamation, arrangement, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with; and

(ii) an Opinion of Counsel that all conditions precedent thereto and hereunder have been complied with, and shall promptly mail notice thereof to all Holders. Failure to mail such notice or any defect therein shall not affect the validity of such transaction and such supplemental indenture.

5.10 Trustee’s Disclaimer

(a) The Trustee shall have no duty to determine when an adjustment under this Article 5 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in acting and relying upon, an Officers’ Certificate and Opinion of Counsel, including the Officers’ Certificate with respect thereto which the Corporation is obligated to file with the Trustee pursuant to Section 5.7. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Debentures, and the Trustee shall not be responsible for the Corporation’s failure to comply with any provisions of this Article 5.

(b) The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 5.9, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in acting and relying upon, the Officers’ Certificate and Opinion of Counsel, with respect thereto which the Corporation is obligated to file with the Trustee pursuant to Section 5.9.

Article 6
SUBORDINATION OF SECURITIES

6.1 Applicability of Article

(a) The indebtedness, liabilities and obligations of the Corporation hereunder (except as provided in Section 10.8) or under the Debentures, whether on account of principal, premium, interest, Make-Whole Payment or otherwise, but excluding the issuance of Common Shares or other securities upon any conversion pursuant to Article 5, or at maturity pursuant to Article 4 (collectively, the “Debenture Liabilities”), shall be subordinated and postponed and subject in right of payment, to the extent and in the manner hereinafter set forth in the following sections of this Article 6, to the full and final payment of all Senior Indebtedness and each holder of any such Debenture by his acceptance thereof agrees to and shall be bound by the provisions of this Article 6.

(b) The Senior Indebtedness shall continue to be Senior Indebtedness and shall be entitled to the benefits of this Article 6 irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness and notwithstanding that no express written subordination

agreement may have been entered into between any Senior Creditor and the Trustee or any of the Holders of Debentures.

(c) Holders of Debentures shall have no right to institute or commence any proceedings for the appointment of a receiver or receiver and manager or trustee for the Corporation or any Subsidiary or for any part of the property of the Corporation or any Subsidiary or any other proceeding relating to the Corporation or any Subsidiary under any bankruptcy, insolvency, reorganization, arrangement or readjustment of debt, law or statute of any jurisdiction, whether now or hereafter in effect.

(d) Holders of the Debentures shall not be entitled to enforce their rights and remedies, other than the right to convert their Debentures pursuant to Section 5.1, if applicable, following the occurrence of a Default or an Event of Default unless, and only to the extent that, payment on account of the Debentures would not be restricted at such time pursuant to Section 6.5(a).

(e) No Holder of Debentures will take any steps whatsoever whereby the priority or rights of holders of any Senior Indebtedness may be defeated or impaired and no Holder of Debentures shall assert any right or claim, whether in law or equity, which might impair the validity and effectiveness of the priority of the Senior Indebtedness in accordance with the terms hereof.

6.2 Order of Payment

In the event of any voluntary or involuntary dissolution, winding-up or liquidation, or any bankruptcy, insolvency, receivership, creditor enforcement or realization or other similar proceedings relating to the Corporation or any of its Subsidiaries (to the extent the Corporation or any of its Subsidiaries is liable and as a principal obligor, guarantor or otherwise for any of the Senior Indebtedness and in respect of the Debentures) or any of its respective property (whether voluntary or involuntary, partial or complete) or any other marshalling of the assets and liabilities of the Corporation or such Subsidiary, any reorganization or any sale, distribution or other transfer of all or substantially all of the assets of the Corporation or such Subsidiary:

(a) all Senior Indebtedness, together with accrued and interest and premium, if any, shall first be paid in full, or provision made for such payment, before any payment or distribution is made on account of Debenture Liabilities;

(b) any payment or distribution of assets of the Corporation or such Subsidiary, whether in cash, property or securities, to which the Holders of the Debentures or the Trustee on behalf of such holders would be entitled except for the provisions of this Article 6, shall be paid or delivered by the trustee in bankruptcy, receiver, assignee for the benefit of creditors, or other liquidating agent making such payment or distribution, directly to the applicable Senior Creditors to the extent necessary to pay all Senior Indebtedness in full after giving effect to any concurrent payment or distribution, or provision therefor, to such Senior Creditors

before any payment or distribution is made to the Holders of Debentures or the Trustee; and

(c) to the extent the Corporation is liable as a principal obligor, guarantor or otherwise for any of the Senior Indebtedness, the Senior Creditors or a receiver or a receiver-manager of the Corporation or of all or part of its assets or any other enforcement agent may sell, mortgage, or otherwise dispose of the assets of the Corporation in whole or in part, free and clear of all Debenture Liabilities and without the approval of the Holders of Debentures or the Trustee or any requirement to account to the Trustee or the Holders.

The rights and priority of the Senior Indebtedness and the subordination pursuant hereto shall not be affected by:

(i) the time of incurrence or extension of any Senior Indebtedness;

(ii) the time, sequence or order of creating, granting, executing, delivering of, or registering, perfecting or failing to register or perfect any security notice, caveat, financing statement or other notice in respect of the Senior Security, if any;

(iii) the time or order of the attachment, perfection or crystallization of any security constituted by the Senior Security, if any;

(iv) the taking of any collection, enforcement or realization proceedings pursuant to the Senior Indebtedness;

(v) the date of obtaining of any judgment or order of any bankruptcy court or any court administering bankruptcy, insolvency or similar proceedings as to the entitlement of the Senior Creditors, or any of them, or the Holders of Debentures or other creditors of the Corporation or any of them to any money or property of the Corporation;

(vi) the failure to exercise any power or remedy reserved to the Senior Creditors under documents evidencing the Senior Indebtedness or under the Senior Security or to insist upon a strict compliance with any terms thereof;

(vii) whether any Senior Security is now perfected, hereafter ceases to be perfected, is avoidable by any trustee in bankruptcy or like official or is otherwise set aside, invalidated or lapses;

(viii) the date of giving or failing to give notice to or making demand upon the Corporation; or

(ix) to the extent permitted by applicable law, any other matter whatsoever.

6.3 Waiver by Trustee

The Trustee, on behalf of each of the Holders of Debentures, hereby waives any and all rights to require a Senior Creditor to pursue or exhaust any rights or remedies with respect to the Corporation or any property and assets subject to the Senior Security or in any other manner to require the marshalling of property, assets or security in connection with the exercise by the Senior Creditors of any rights, remedies or recourses available to them.

6.4 Obligation to Pay Not Impaired

Nothing contained in this Article 6 or elsewhere in this Indenture or in the Debentures is intended to or shall impair, as between the Corporation, its creditors other than the Senior Creditors, and the Holders of the Debentures, the obligation of the Corporation, which is absolute and unconditional, to pay to the Holders of the Debentures the principal of, premium or Make-Whole Payment, if any, and interest on the Debentures, as and when the same shall become due and payable in accordance with their terms, or affect the relative rights of the Holders of the Debentures and creditors of the Corporation other than the Senior Creditors, nor shall anything herein or therein prevent the Trustee or the Holder of any Debentures from exercising all remedies otherwise permitted by applicable law or under this Indenture upon default under this Indenture, subject to the rights, if any, under this Article 6 of the Senior Creditors.

6.5 No Payment if Senior Indebtedness in Default

(a) No payment of any principal of, premium or Make-Whole Payment, if any, or interest (or any other amounts payable) in respect of the Debentures or in respect of any Redemption Price may be made, and neither the Trustee nor any Holder of Debentures will be entitled to demand, accelerate, institute proceedings (other than as may be necessary to preserve a limitation period) for the collection of, or receive any payment or benefit (including, without limitation, by set-off, combination of accounts or realization of security or otherwise in any manner whatsoever) on account of indebtedness represented by the Debentures:

(i) in a manner inconsistent with the terms (as they exist on the date of issue) of the Debentures;

(ii) unless all payments of principal and interest then due and payable on all Senior Indebtedness for borrowed money have been made;

(iii) at any time when any amount is in arrears under any Senior Indebtedness or a default or an event of default has occurred under Senior Indebtedness, and such a default or event of default is continuing unless and until such Senior Indebtedness has been paid and satisfied in full or such default or event of default shall have been cured or waived in writing in accordance with the provisions of such Senior Indebtedness; or

(iv) if the making of any such payment or the taking of any such action would create, including by the lapse of time or giving of notice, a default or an event of default under any Senior Indebtedness unless and until such Senior Indebtedness has been satisfied in full or the making of any such payment or taking of such action would no longer create, including by the lapse of time or giving of notice, a default or an event of default under any Senior Indebtedness.

(b) If, notwithstanding Section 6.2(b) or Section 6.5(a), the Trustee receives any payment when such payment should have been paid to the Senior Creditors pursuant to Section 6.2(b) or is prohibited by Section 6.5(a), as the case may be, and if the Trustee has not distributed the payment, the Trustee shall, upon receiving an Officer’s Certificate to that effect, return such payment to the Corporation; provided, however, that the foregoing shall in no way prohibit, restrict or prevent the Trustee from taking such actions as may be necessary to preserve claims of the Trustee and/or the Holders of the Debentures under this Indenture in any bankruptcy, reorganization or insolvency proceeding (including, without limitation, the filing of proofs of claim in any such bankruptcy, reorganization or insolvency proceedings by or against the Corporation and exercising its rights to vote as an unsecured creditor under any such bankruptcy, reorganization or insolvency proceedings commenced by or against the Corporation).

6.6 Payment on Debentures Permitted

Nothing contained in this Article 6 or elsewhere in this Indenture, or in any of the Debentures, shall affect the obligation of the Corporation to make, or prevent the Corporation from making, at any time except as prohibited by Section 6.5, any payment of principal of, premium or Make-Whole Payment, if any, or interest on the Debentures. The fact that any such payment is prohibited by Section 6.5 shall not prevent the failure to make such payment from being an Event of Default hereunder. Nothing contained in this Article 6 or elsewhere in this Indenture, or in any of the Debentures, shall prevent the conversion of the Debentures when otherwise permitted under this Indenture or, except as prohibited by this Article 6, the application by the Trustee of any monies deposited with the Trustee hereunder for the purpose, to the payment of or on account of the Debenture Liabilities.

6.7 Confirmation of Subordination

Each Holder of Debentures by his or her acceptance of the Debentures authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate, and as relying on the advice of counsel, to effect the subordination as provided in this Article 6 and appoints the Trustee as his attorney-in-fact for any and all such purposes. Upon request of the Corporation, and upon being furnished with an Officers’ Certificate stating that one or more named Persons are Senior Creditors and specifying the amount and nature of the Senior Indebtedness of such Senior Creditor, the Trustee shall enter into a written agreement or agreements with the Corporation and the Person or Persons named in such Officers’ Certificate providing that such Person or Persons are entitled to all the rights and benefits of this Article 6 as

a Senior Creditor. Such agreement shall be conclusive evidence that the indebtedness specified therein is Senior Indebtedness, provided however, nothing herein shall impair the rights of any Senior Creditor who has not entered into such an agreement.

6.8 Knowledge of Trustee

Notwithstanding the provisions of this Article 6 or any provision in this Indenture or in the Debentures, the Trustee will not be charged with knowledge of any Senior Indebtedness or of any default in the payment thereof, or of the existence of any other fact that would prohibit the making of any payment of monies to or by the Trustee, or the taking of any other action by the Trustee, unless and until the Trustee has received written notice thereof from the Corporation, any Holder of Debentures or any Senior Creditor.

6.9 Trustee May Hold Senior Indebtedness

The Trustee is entitled to all the rights set forth in this Article 6 with respect to any Senior Indebtedness at the time held by it, to the same extent as any other Senior Creditor, and nothing in this Indenture deprives the Trustee of any of its rights as such Senior Creditor.

6.10 Rights of Holders of Senior Indebtedness Not Impaired

No right of any present or future Senior Creditor 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 Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

6.11 Altering the Senior Indebtedness

The Senior Creditors have the right to extend, renew, modify or amend the terms of the Senior Indebtedness or any security therefor 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 of Debentures or the Trustee and without affecting the provisions of this Article 6 or the other liabilities and obligations of the parties to this Indenture or the Holders of Debentures or the Trustee.

6.12 Right of Holder to Convert Not Impaired

The subordination of the Debentures to the Senior Indebtedness and the provisions of this Article 6 do not impair in any way the right of a Holder of Debentures to convert its Debentures pursuant to Article 5.

6.13 Invalidated Payments

In the event that any of the Senior Indebtedness shall be paid in full and subsequently, for whatever reason, such formerly paid or satisfied Senior Indebtedness becomes unpaid or

unsatisfied, the terms and conditions of this Article 6 shall be reinstated and the provisions of this Article 6 shall again be operative until all Senior Indebtedness is repaid in full, provided that such reinstatement shall not give the Senior Creditors any rights or recourses against the Trustee or the Holders of Debentures for amounts paid to the Holders of Debentures subsequent to such payment or satisfaction in full and prior to such reinstatement.

6.14 Contesting Security

The Trustee, on behalf of the Holders of Debentures, agrees that it shall not contest or bring into question the validity, perfection or enforceability of any of the Senior Security, or the relative priority of the Senior Security.

Article 7
COVENANTS

7.1 Payment of Debentures

(a) The Corporation shall promptly make all payments in respect of the Debentures on the dates and in the manner provided in the Debentures and this Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Corporation) holds by 11:00 a.m., Toronto time, three Business Days preceding that date money and by 11:00 a.m. on the Business Day immediately preceding that date Common Shares sufficient to make the payment. Accrued and unpaid interest on any Debenture that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid by cheque or wire transfer to the Person in whose name that Debenture is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Corporation maintained for such purpose (or as otherwise directed by such Person and in the manner so directed). Any Make-Whole Payment or Redemption Price, if payable, shall be considered paid on the applicable date due if on the Business Day preceding the Final Instalment Date, Redemption Date or Mandatory Redemption Date, as applicable, the Trustee holds, in accordance with this Indenture, money and/or Common Shares, if applicable, sufficient to pay all such amounts then due. The Corporation shall, to the fullest extent permitted by law, pay interest in immediately available funds on overdue principal amount and interest at the annual rate borne by the Debentures compounded quarterly, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand.

(b) Payment of the principal of, interest, Make-Whole Payment or other amounts, if any, on the Debentures shall be made by cheque mailed to the address of the Holder on the applicable record date entitled thereto as such address appears in the Register; provided further that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election and direction of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

(c) Notwithstanding Section 7.1(b), if Debentures are represented by one or more Global Debentures, interest payments on Global Debentures will be made by wire transfer to the Trustee no later than 11:00 a.m. on the Business Day immediately preceding the Interest Payment Date for delivery to the Depository or its nominee, as the case may be. Principal amount payments on Global Debentures will be made by wire transfer delivered to the Depository or its nominee, as the case may be, at maturity against surrender to the Trustee of the Global Debenture. As long as the Depository or the nominee is the registered owner of a Global Debenture, the Depository or the nominee, as the case may be, will be considered the sole owner of the Global Debenture for the purposes of receiving payments on the Global Debenture and for all other purposes under the Indenture and the Global Debenture. The forwarding of any such payments to the Depository or the nominee shall satisfy and discharge the liability in respect of such amounts on such Debenture to the extent of the sum represented thereby (plus the amount of any tax deducted or withheld).

7.2 Reporting Requirements

(a) The Corporation shall file with the Trustee within 15 days after the filing thereof with securities commissions or similar regulatory authorities in each of the provinces of Canada, copies of all reports and other information and documents that the Corporation is required to file with such securities commissions or similar regulatory authorities; provided however that any reports, information and documents filed on The System for Electronic Document Analysis and Retrieval (SEDAR) shall be deemed to be filed with the Trustee; and provided further that any confidential material change report (as described in Part 7 of National Instrument 51-102 Continuous Disclosure Obligations) shall not be filed with the Trustee until such report is made public. The Corporation will provide copies of such reports, information and documents to Holders upon request.

(b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Corporation’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

7.3 Compliance Certificates

The Corporation shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Corporation (beginning with the fiscal year ending December 31, 2014), an Officers’ Certificate as to the signers’ knowledge of the Corporation’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not the signers know of any Default or Event of Default. If such signers know of such a Default or Event of Default, the Officers’ Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of this Section 7.3, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture.

7.4 Further Instruments and Acts

Upon request of the Trustee, the Corporation will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

7.5 Maintenance of Corporate Existence

Subject to Article 8, the Corporation will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

7.6 Maintenance of Office or Agency

The Corporation will maintain an office or agency of the Trustee, Registrar and Paying Agent and Conversion Agent where Debentures may be presented or surrendered for payment, where Debentures may be surrendered for registration of transfer, purchase, conversion or redemption and where notices and demands to or upon the Corporation in respect of the Debentures and this Indenture may be served. The Corporate Trust Office shall be the office or agency for all of the aforesaid purposes. The Corporation shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Corporation fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 14.1. The Corporation may also from time to time designate one or more other offices or agencies where the Debentures may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Corporation of its obligation to maintain an office or agency.

7.7 Withholding Matters

All payments made by or on behalf of the Corporation under or with respect to the Debentures (including, without limitation, any penalties, interest and other liabilities related thereto) will be made free and clear of and without withholding or deduction for, or on account of, any present or future tax, duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or elsewhere, or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Withholding Taxes”), unless the Corporation is required by law or the interpretation or administration thereof, to withhold or deduct any amounts for, or on account of, Withholding Taxes. If the Corporation is so required to withhold or deduct any amount for or on account of Withholding Taxes from any payment made under or with respect to the Debentures, the Corporation shall deduct and withhold such Withholding Taxes from any payment to be made under or with respect to the Debentures and, provided that the Corporation forthwith remits such withheld amount to the relevant governmental authority or agency, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Corporation’s obligations under the

Debentures. There is no obligation on the Corporation to gross-up or pay additional amounts to a Holder in respect of such deductions or withholdings. For greater certainty, if any amount is required to be deducted or withheld in respect of Withholding Taxes upon a conversion of a Debenture, the Corporation shall be entitled to liquidate such number of Common Shares (or other securities) issuable as a result of such conversion as shall be necessary in order to satisfy such requirement. The Corporation shall provide the Trustee with copies of receipts or other communications relating to the remittance of such withheld amount or the filing of any forms received from such government authority or agency promptly after receipt thereof.

(i) the Person formed by such consolidation or into which the Corporation is amalgamated or merged, or the Person which acquires by sale, conveyance, transfer or lease all or substantially all of the properties and assets of the Corporation is a corporation incorporated and existing under the laws of Canada or any province or territory thereof or the laws of the United States and such corporation (if other than the Corporation or the continuing corporation resulting from the amalgamation of the Corporation with another corporation under the laws of Canada or any province or territory thereof) expressly assumes, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the obligations of the Corporation under the Debentures and this Indenture and the performance or observance of every covenant and provision of this Indenture and the Debentures required on the part of the Corporation to be performed or observed and the conversion rights shall be provided for in accordance with Article 5, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by the Person (if other than the Corporation or the continuing corporation resulting from the amalgamation of the Corporation with another corporation under the laws of Canada or any province or territory thereof) formed by such consolidation or into which the Corporation shall have been merged or by the Person which shall have acquired the Corporation’s assets;

(ii) after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and

(iii) if the Corporation or the continuing corporation resulting from the amalgamation of the Corporation with another corporation under the laws of Canada or any province or territory thereof will not be the resulting, continuing or surviving corporation, the Corporation shall have, at or prior to the effective date of such consolidation, amalgamation, merger or sale, conveyance, transfer or lease, delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer complies with this Article and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Article, and that all conditions precedent herein provided for relating to such transaction have been complied with.

8.2 Successor Substituted

Upon any consolidation of the Corporation with, or amalgamation or merger of the Corporation into, any other Person or any sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Corporation and its Subsidiaries, taken as a whole, in accordance with Section 8.1, the successor Person formed by such consolidation or into which the Corporation is amalgamated or merged or to which such sale, conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Corporation under this Indenture with the same effect as if such successor Person had been named as the Corporation herein, and thereafter, except in the case of a lease, and except for obligations the predecessor Person may have under a supplemental indenture entered into pursuant to Section 8.1(a)(iii), the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Debentures.

Article 9
DEFAULT AND REMEDIES

9.1 Events of Default

(a) An “Event of Default” shall occur if:

(i) the Corporation shall fail to pay when due the principal or premium, if any, on the Debentures when the same becomes due and payable whether at the Maturity Date, upon redemption, acceleration or otherwise and such default continues for a period of five Business Days;

(ii) the Corporation shall fail to pay an instalment of cash interest or Make-Whole Payment, if any, on any of the Debentures, which failure continues for 30 days after the date when due;

(iii) the Corporation shall fail to deliver when due all cash and Common Shares deliverable upon conversion of the Debentures, which failure continues for 30 days; or

(iv) the Corporation shall fail to perform or observe any other material term, covenant or agreement contained in the Debentures or this Indenture for a period of 30 days after the receipt by the Corporation of a Notice of Default specifying such failure; or

(v) if at any time a default is made by the Corporation or any Material Subsidiary, with respect to any indebtedness (excluding amounts due to the Holders), where the aggregate principal amount of such indebtedness exceeds an amount equal to the greater of 2% of the Consolidated Net Worth at such time and $100,000,000, and (A) if the default is a payment default, such default continues to exist for a period exceeding 30 days; provided that if the payment obligation to which the default relates is accelerated, then the default shall constitute an Event of Default immediately following such acceleration, and (B) if the default is not a payment default, then as a result of the default and the passing of any applicable cure period, the maturity of the obligation is accelerated; provided that, in each case, if the default is cured prior to acceleration of the Debentures, then the Event of Default shall be deemed to have been cured;

(b) the Corporation pursuant to or within the meaning of any Bankruptcy Law:

(i) commences as a debtor a voluntary case or proceeding;

(ii) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it;

(iii) consents to the appointment of a Receiver of it or for all or substantially all of its property;

(iv) makes a general assignment for the benefit of its creditors;

(i) grants relief against the Corporation in an involuntary case or proceeding or adjudicates the Corporation insolvent or bankrupt;

(ii) appoints a Receiver of the Corporation or for all or substantially all of the property of the Corporation; or

(iii) orders the winding up or liquidation of the Corporation;

and in each case the order or decree remains unstayed and in effect for 60 consecutive days. The term “Bankruptcy Law” means the Bankruptcy and Insolvency Act (Canada) (or any successor thereto), the Companies’ Creditors Arrangement Act (Canada) (or any successor thereto), or Title 11, United States Code (or any successor thereto) or any similar Canadian federal or provincial, United States or foreign law for the relief of debtors. The term “Receiver” means any receiver (interim or otherwise), trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law.

(d) Notwithstanding Section 9.1(a), no Event of Default under Sections 9.1(a)(iv) or (v) shall occur until the Trustee notifies the Corporation in writing, or the Holders of at least 25% in aggregate principal amount of the Debentures then outstanding notify the Corporation and the Trustee in writing, of the Default (a “Notice of Default”), and the Corporation does not cure the Default within the time specified in Sections 9.1(a)(iv) or (v), as applicable, after receipt of such notice. A notice given pursuant to this Section 9.1(d) shall be given by registered or certified mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under this Section 9.1(d) is cured, it ceases.

(e) The Corporation will deliver to the Trustee, within five Business Days after becoming aware of the occurrence of a Default or Event of Default, written notice thereof.

(f) The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to the Trustee by the Corporation, a Paying Agent (if other than the Trustee), any Holder or any agent of any Holder, including reference to the Section of this Indenture under which the Default or Event of Default has occurred.

9.2 Acceleration

If an Event of Default (other than an Event of Default specified in Sections 9.1(b) or (c)) occurs and is continuing with respect to the Corporation, the Trustee may, by notice to the Corporation, or the Holders of at least 25% in aggregate principal amount of the Debentures then outstanding may, by notice to the Corporation and the Trustee, declare the principal amount and accrued and unpaid interest, if any, through the date of declaration on all the Debentures to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in Sections 9.1(b) or (c) occurs in respect of the Corporation and is continuing, the principal amount and accrued but unpaid interest, if any, on all the Debentures shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Debentures. The Holders of a majority in aggregate principal amount of the

Debentures then outstanding by notice to the Trustee may rescind an acceleration and its consequences. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

9.3 Other Remedies

(a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy under this Indenture, or by proceeding at law or in equity to collect payment of the principal amount and accrued and unpaid interest, if any, on the Debentures or to enforce the performance of any provision of the Debentures or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Debentures or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy under this Indenture is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by applicable law.

9.4 Waiver of Defaults and Events of Default

Subject to Sections 9.7 and 12.2, the Holders of 662/3% in aggregate principal amount of the Debentures then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequences. When a Default or Event of Default is waived in accordance with this Section 9.4, it is cured and ceases.

9.5 Control by Majority

The Holders of a majority in aggregate principal amount of the Debentures then outstanding may 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 it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered funding and indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

9.6 Limitations on Suits

(a) A Holder may not pursue any remedy with respect to this Indenture or the Debentures (except actions for payment of overdue principal, premium or Make-Whole Payment, if any, or interest or for the conversion of the Debentures pursuant to Article 5) unless:

(i) the Holder gives to the Trustee written notice of a continuing Event of Default;

(ii) the Holders of at least 25% in aggregate principal amount of the then outstanding Debentures make a written request to the Trustee to pursue the remedy;

(iv) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of funding and indemnity; and

(v) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Debentures then outstanding.

(b) No Holder of a Debenture shall have any right under any provision of this Indenture or the Debentures to affect, disturb, or prejudice the rights of another Holder of a Debenture or to obtain a preference or priority over another Holder of a Debenture.

9.7 Rights of Holders to Receive Payment and to Convert

Notwithstanding any other provision of this Indenture, the right of any Holder of a Debenture to receive payment of the principal amount, interest, Make-Whole Payment or Redemption Price, if any, in respect of the Debentures held by such Holder, on or after the respective due dates expressed in the Debentures and this Indenture (whether upon redemption, repurchase or otherwise), and to convert such Debentures in accordance with Article 5, and to bring suit for the enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with Article 5, is absolute and unconditional and shall not be impaired or affected without the consent of the Holders of the majority of the aggregate principal amount of Debentures then outstanding.

9.8 Collection Suit by Trustee

If an Event of Default described in clause (i) or (ii) of Section 9.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Corporation or another obligor on the Debentures for the whole amount owing with respect to the Debentures and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

9.9 Trustee may File Proofs of Claim

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Corporation (or any other obligor on the Debentures), its creditors or its property and shall be entitled and

empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Receiver in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 10.8, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Debentures or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

shall be enforceable by, the Trustee in each of its capacities hereunder, including, without limitation as Paying Agent, Registrar and Conversion Agent, and to each agent, custodian and other Person employed to act hereunder.

(k) The Trustee shall not be required to exercise any powers and shall not have any responsibilities except as expressly provided in this Indenture and shall have no obligation to recognize nor have any liability or responsibility arising under any other document or agreement to which the Trustee is not a party, notwithstanding that reference thereto may be made herein.

10.5 Individual Rights of Trustee

The Trustee in its individual or any other capacity may become the owner or pledgee of Debentures and may otherwise deal with the Corporation or an Affiliate of the Corporation with the same rights it would have if it were not Trustee.

10.6 Trustee’s Disclaimer

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Debentures or of any recitals or statements of fact herein. It shall not be accountable for the Corporation’s use of the Debentures or any proceeds from the Debentures and it shall not be responsible for any statement in the Debentures other than its certificate of authentication.

10.7 Notice of Default or Events of Default

Subject to Sections 10.3(c) and 10.4(i), if a Default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder of a Debenture (and to beneficial owners as required by applicable law) notice of all uncured Defaults or Events of Default known to it within 30 days after such becomes known to the Trustee. However, the Trustee may withhold the notice if and for so long as it in good faith determines that withholding such notice is in the interests of Holders of Debentures, provided the Trustee gives notice to the Corporation in writing, and except in the case of a Default or an Event of Default in payment of any amount payable under this Indenture or the Debentures when due or, or the Corporation’s failure to convert Debentures when obligated to convert them.

10.8 Compensation

The Trustee shall be entitled to compensation and to be remunerated for the performance of its duties hereunder as separately agreed upon with the Corporation in the Fee Letter and the Corporation shall reimburse the Trustee, upon its request, for all reasonable costs and expenses, disbursements and advances incurred or made by the Trustee in the administration or execution of its duties under this Indenture (including the reasonable and documented compensation and disbursements of its counsel and all other advisers and assistants not regularly in its employ), both before any Default and thereafter until all duties of the Trustee under this Indenture shall be finally and fully performed. The Trustee’s compensation shall not be limited

by any law on compensation of a trustee of an express trust. Any amount due and owing pursuant to the Fee Letter that remains unpaid by the Corporation 30 days after written request for payment will bear interest from the expiration of such period at a rate per annum equal to the then current rate charged by the Trustee, payable by the Corporation on demand by the Trustee. After Default, all amounts so payable and the interest thereon shall be payable out of any funds coming into the possession of the Trustee or its successors in the trusts hereunder in priority to any payment of any amount payable under this Indenture or the Debentures. Such remuneration shall continue to be payable until the trusts hereof shall be finally wound up, whether or not the trusts of this Indenture shall be in course of administration by or under the direction of a court.

10.9 Indemnification

(a) Subject to Sections 10.9(b) and 10.11, the Trustee, its successors and permitted assigns, and every attorney, manager, agent, delegate or other person appointed by either of them under this Indenture (“Indemnified Parties”) are each hereby indemnified by the Corporation from and against all losses, liabilities, claims, proceedings, actions, demands, suits, assessments, damages, interest, penalties and all costs and expenses in connection therewith (collectively, “Losses”) which each may incur or which may be made or brought against any of them as a result of the execution or purported execution of the duties or obligations of the Trustee under or pursuant to this Indenture or under any indentures or agreements made or to be made between the Trustee and the Corporation relating to the function of the Trustee as Trustee or in any of its capacities as Agent for the Debentures or arising from or in connection with any actions or omissions of the Indemnified Parties in respect of this Indenture. This indemnity shall survive the resignation or removal of the Trustee and the termination or discharge of this Indenture.

(b) If any action or claim shall be brought against an Indemnified Party in respect of which it appears to the Trustee that indemnity may be sought by such Indemnified Party from the Corporation pursuant to Section 10.9(a), the Trustee shall as soon as practicable notify the Corporation in writing of such action or claim. Failure by the Trustee to so notify the Corporation shall not relieve the Corporation of its obligation of indemnification hereunder unless (and only to the extent that) such failure results in forfeiture by the Corporation of substantive rights and defences. The Corporation shall, subject as hereinafter in this Section 10.9(b) provided, be entitled (but not required) to assume the defence of any such action or claim through legal counsel selected by the Corporation and acceptable to the Trustee acting reasonably and no admission of liability shall be made by the Corporation or by any Indemnified Party without, in each case, the prior written consent of the other of them, such consent not to be unreasonably withheld. An Indemnified Party shall have the right to employ separate counsel of its choosing in any such action or claim and participate in the defence thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the Corporation fails to assume the defence of such action or claim within a reasonable period of time; (ii) the employment of such counsel has been authorized in writing by the Corporation; or (iii) the named parties to such action or claim include both the person seeking indemnity and the Corporation and the person seeking indemnity shall have been advised by counsel that there may be one or more legal defences available to the person seeking indemnity that are different from or in addition to those available to the Corporation, as the case may be, in which case, if the

person seeking indemnity notifies the Corporation in writing that it elects to employ its own legal advisers at the expense of the Corporation, the Corporation shall not have the right to assume such defence on behalf of the person seeking indemnity but shall be liable to pay the reasonable fees and expenses of such counsel, it being understood that such counsel shall be acceptable to the Corporation, acting reasonably, and the Corporation shall not in connection with any one action or claim or separate but substantially similar or related actions or claims in the same jurisdiction arising out of the same general allegations or circumstances be liable for the reasonable fees and expenses of more than one separate law firm for all Indemnified Parties.

(c) Computershare Trust Company of Canada has entered into this agreement and any document delivered in connection herewith solely in its capacity as Trustee and not in its personal capacity. Whenever any reference is made in this Indenture or in any document delivered in connection herewith, to an act to be performed by the Trustee, such reference shall be construed and applied for all purposes as if it referred to an act to be performed by the Trustee for and on behalf of the Corporation. Any and all of the representations, undertakings, covenants, indemnities, agreements and other obligations (in this section, collectively “obligations”) made on the part of the Trustee herein of therein are made and intended not as personal obligations of or by Computershare Trust Company of Canada or for the purpose or with the intention of binding Computershare Trust Company of Canada in its personal capacity, but are made and intended for the purpose of binding only the Trustee in its capacity as Trustee or Agent. No property or assets of Computershare Trust Company of Canada, whether owned beneficially by it in its personal capacity or otherwise, will be subject to levy, execution or other enforcement procedures with regard to any of the Trustee’s obligations hereunder. No recourse may be had or taken, directly or indirectly, against Computershare Trust Company of Canada in its personal capacity, or any incorporator, shareholder, officer, director, employee or agent of Computershare Trust Company of Canada or of any predecessor or successor of Computershare Trust Company of Canada, with regards to the Trustee’s obligations hereunder.

10.10 Reliance on Minutes

The Trustee shall not be responsible for having acted upon any resolution purporting to have been passed at any meeting of the Holders held pursuant to Article 13 in respect whereof minutes have been made and signed even though it may subsequently be found that there was some defect in the constitution of the meeting or the passing of the resolution or that for any reason the resolution was not valid or binding upon the Holders.

10.11 No Entitlement to Indemnity

Notwithstanding any other provision of this Article 10, if and to the extent that a court of competent jurisdiction, in a final non-appealable judgment in a proceeding in which the Trustee or any other Indemnified Party is named as a party, determines that Losses under an action or claim were caused primarily and directly by or resulted primarily and directly from an Indemnified Party’s fraud, negligence or wilful misconduct, the Indemnified Parties shall not be entitled to any indemnity hereunder and shall be required to reimburse any funds advanced by the Corporation to the Indemnified Parties pursuant to the indemnity set out in Section 10.9(a) in

respect of such action or claim and thereafter, the indemnity set out in Section 10.9(a) shall cease to apply to the Indemnified Parties in respect of such action or claim.

10.12 Force Majeure

The Trustee shall not be liable, or held in breach of this Indenture, if prevented, hindered, or delayed in the performance or observance of any provision contained herein by reason of act of God, riots, terrorism, acts of war, epidemics, governmental action or judicial order, earthquakes, or any other similar causes (including, but not limited to, mechanical, electronic or communication interruptions, disruptions or failures).

(f) If at any time:

(i) the Trustee shall fail to comply with the provisions of Section 10.3; or

(ii) the Trustee shall cease to be eligible under Section 10.14 and shall fail to resign after written request therefor by the Corporation or by any Holder; or

(iii) the Trustee shall become incapable of acting or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any case,

(iv) the Corporation may remove the Trustee; or

(v) in the case of Section 10.13(f)(i), a Holder and any other interested party, and in the case of Sections 10.13(f)(ii) and (iii), any Holder may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall mail notice of its succession to each Holder.

(h) A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee after its succession.

10.14 Successor Trustee by Merger, etc.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the administration of this Indenture) to another corporation the resulting, surviving or transferee corporation, without any further act, shall be the successor Trustee; provided such transferee corporation shall qualify and be eligible under Section 10.2. Such successor Trustee shall promptly mail notice of its succession to the Corporation and each Holder (and to beneficial owners as required by applicable law).

10.15 Third Party Interests

Each party to this Indenture hereby represents to the Trustee that any account to be opened by, or interest to be held by, the Trustee in connection with this Indenture, for or to the credit of such party, either (a) is not intended to be used by or on behalf of any third party; or (b) is intended to be used by or on behalf of a third party, in which case such party hereto agrees

to complete and execute forthwith a declaration in the Trustee’s prescribed form as to the particulars of such third party.

10.16 Trustee Not Bound to Act

The Trustee shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions legislation, regulation or guideline. Further, should the Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions legislation, regulation or guideline, then it shall have the right to resign on 10 days’ written notice to the Corporation, provided: (a) that the Trustee’s written notice shall describe the circumstances of such non-compliance; and (b) that if such circumstances are rectified to the Trustee’s satisfaction within such 10 day period, then such resignation shall not be effective.

If at any time a material conflict of interest exists in respect of the Trustee’s role as Trustee under this Indenture that is not eliminated within 90 days after the Trustee becomes aware that such a material conflict of interest exists, the Trustee shall resign from the trusts under this Indenture by giving notice in writing of such resignation and the nature of such conflict to the Corporation at least 21 days prior to the date upon which such resignation is to take effect, and shall on the effective date of such resignation be discharged from all further duties and liabilities hereunder. The validity and enforceability of this Indenture and any Debentures shall not be affected in any manner whatsoever by reason only of the existence of a material conflict of interest of the Trustee.

(b) After an amendment, supplement or waiver under this Section 12.2 becomes effective, the Corporation shall promptly mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver.

Article 13
MEETINGS OF HOLDERS

13.1 Convening of Meetings

The Trustee or the Corporation may at any time convene a meeting of the Holders and the Trustee shall do so upon a requisition in writing by the Holders of Debentures representing not less than 25% of the aggregate principal amount of Debentures and upon being funded and indemnified to its reasonable satisfaction by the Corporation or by the Holders signing such request against the costs which may be incurred in connection with the calling and holding of such meeting. If the Trustee fails within 30 days after receipt of any such request and such indemnity to give notice convening a meeting, the Corporation or such Holders, as the case may be, may convene such meeting. Every meeting shall be held in Toronto, Ontario or such other place in Canada as the Corporation and the Trustee may decide.

13.2 Notice of Meeting

Notice of all meetings of Holders shall be sent to all Holders entitled thereto within all time periods and in accordance with all legal requirements applicable to meetings of the Corporation’s securityholders (including the requirements of National Instrument 54-101). A copy of the notice shall be sent to the Corporation (unless the meeting shall be convened by the Corporation) and the Trustee (unless the meeting shall be convened by the Trustee). Such notice shall state the time and place at which the meeting is to be held and shall briefly state the nature of the business proposed to be transacted thereat, and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 13. The accidental omission to give notice of any meeting or any irregularity in the notice of any meeting or the non-receipt of any notice by any Holders, the Trustee or the Corporation shall not invalidate any resolution passed or any proceedings taken at any meeting of Holders. Any Holder

present, either in person or by proxy, at any meeting of the Holders shall for all purposes be deemed to have received due notice of such meeting and, where requisite, of the purposes for which such meeting was convened.

13.3 Quorum

A quorum for the transaction of business at any meeting of Holders shall be Holders present in person, or represented by proxy and owning or representing at least 15% of the aggregate principal amount of the Debentures entitled to vote at the meeting. If a quorum is present at the opening of any meeting of Holders, the Holders present or represented may proceed with the business of the meeting notwithstanding that a quorum is not present throughout the meeting. If a quorum is not present within 30 minutes from the time fixed for the holding of a meeting, the meeting, if convened by or on the requisition of Holders, shall be dissolved, but if convened by or on the requisition of the Corporation or the Trustee, then the meeting shall be adjourned to the same day in the next following week (unless such day is not a Business Day, in which case it shall be adjourned to the following Business Day) at the same time and place, and no notice shall be required to be given in respect of such adjourned meeting. At any such adjourned meeting, the Holders present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent at least 15% of the aggregate principal amount of the Debentures then outstanding.

13.4 Chairman

A person (who may, but need not be, a Holder or the proxyholder or representative of a Holder) nominated in writing by the Trustee shall be entitled to take the chair at every meeting of Holders and if no person is so nominated or if at any meeting a person so nominated shall not be present within five minutes after the time appointed for holding the meeting the Holders present in person or by proxy shall choose any one of their number to be Chairman.

13.5 Attendance

The Trustee and the Corporation and their duly authorized representatives may attend and speak at any such meeting.

13.6 Power to Adjourn

The Chairman of a meeting at which a quorum of Holders is present may, with the consent of the Holders of a majority of the aggregate principal amount of the Debentures present or represented thereat, adjourn such meeting, and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

13.7 Voting

(a) Every question submitted to a meeting of the Holders shall be decided in the first instance by a show of hands unless a poll is demanded pursuant to Section 13.9. The Chairman shall not on either a show of hands or a poll have a casting vote. On a show of hands, every Holder (or its duly appointed proxy) who (being an individual) is present in person or (being a corporation) is present by its duly authorized representative shall have one vote.

(b) In the case of a Global Debenture, the Depository may appoint or cause to be appointed a Person or Persons as proxies and shall designate the number of votes entitled to each such Person, and each such Person shall be entitled to be present at any meeting of Holders and shall be the Persons entitled to vote at such meeting in accordance with the number of votes set out in the Depository’s designation.

13.8 Chairman’s Declarations

At any meeting of the Holders, unless a poll on any question is demanded by the Chairman or by any Holder present in person or by proxy, a declaration by the Chairman that a resolution has been carried or lost or carried by a particular majority shall be conclusive evidence of that fact.

13.9 Polls

If at any meeting of Holders a poll is demanded by one or more Holders or proxyholders for Holders of at least $10,000,000 principal amount of Debentures, a poll shall be taken in such manner and either at once or, subject to Section 13.12, after such adjournment. The demand for a poll may be withdrawn. On a poll every Holder who is present in person or by proxy shall have one vote for each $1,000 principal amount of Debentures held by such Holder on the record date fixed for the meeting.

13.10 Objections and Errors

If (a) any objection shall be raised to the qualification of any voter (whether on a show of hands or on a poll), (b) any votes have been counted which ought not to have been counted or which might have been rejected or (c) any votes have not been counted which ought to have been counted, then the objection or error shall not vitiate the decision of the meeting or adjourned meeting on any resolution unless the same is raised or pointed out at the meeting or, as the case may be, the adjourned meeting at which the vote objected to is given or tendered or at which the error occurs. Any objection or error shall be referred to the Chairman of the meeting and shall only vitiate the decision of the meeting on any resolution if the Chairman decides that the same may have affected the decision of the meeting. The decision of the Chairman on such matters shall be final and conclusive for all purposes.

13.11 Adjournments

The Chairman may with the consent of any meeting at which a quorum is present adjourn the same from time to time and from place to place. If a meeting of Holders is adjourned for less than 30 days, it shall not be necessary to give notice of the adjourned meeting, other than by announcement at the earliest meeting that is adjourned. If a meeting of Holders is adjourned by one or more adjournments for an aggregate of 30 days or more, notice of the adjourned meeting shall be given in the same manner as for an original meeting. Any business may be brought before or dealt with at any adjourned meeting for which no notice is required which might have been brought before or dealt with at the original meeting in accordance with the notice calling same.

13.12 Time and Place of Polls

Any poll demanded at any meeting on the election of a Chairman or on any question of adjournment shall be taken at the meeting without adjournment. A poll demanded on any other question shall be taken at such time and place as the Chairman directs.

13.13 Entitlement to Vote

The Holder or in the case of joint Holders any one of them shall be entitled to vote in respect of any Debenture either in person or by proxy and in the latter case as if such joint Holder were solely entitled thereto and if more than one joint Holder be present at any meeting either personally or by proxy the joint Holder so present who is first named on the relevant Debenture shall alone be entitled to vote in respect thereof.

13.14 Form of Proxy

Every Holder entitled to vote at a meeting of Holders may appoint a proxyholder, or one or more alternate proxyholders, to attend and act as its representative at the meeting in the manner and to the extent authorized and with the authority conferred by the proxy. A proxy shall be in writing executed by the Holder or its attorney and shall conform with the requirements of the Act.

Alternatively, every such Holder which is a body corporate or association may authorize by resolution of its directors or governing body an individual to represent it at a meeting of Holders and such individual may exercise on the Holder’s behalf all the powers it could exercise if it were an individual Holder. The authority of such an individual shall be established by depositing with the Trustee a certified copy of such resolution, or in such other manner as may be satisfactory to the Trustee or the Chairman of the meeting.

If the Holder of record is deceased, his or her personal representative, upon filing with the secretary of the meeting sufficient proof of his or her appointment shall be entitled to exercise the same voting rights at any meeting of the Holders as the Holder of record would have been entitled to exercise if he or she were living.

13.15 Identity of Proxyholder

A proxyholder need not be a Holder.

FORTIS INC.
UNSECURED SUBORDINATED CONVERTIBLE DEBENTURES
DUE JANUARY 9, 2024

Fortis Inc., a corporation continued under the Corporations Act (Newfoundland and Labrador) (the “Corporation”) for value received hereby acknowledges itself indebted and, subject to the provisions of the trust indenture (the “Indenture”) dated as of January 9, 2014 between the Corporation and Computershare Trust Company of Canada (the “Trustee”), promises to pay to the registered holder of this security (the “Debenture”) on January 9, 2024 (the “Maturity Date”), or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture, the principal amount set forth in the attached Schedule 1, in lawful money of Canada on presentation and surrender of this Debenture at the main branch of the Trustee in Toronto, Ontario in accordance with the terms of the Indenture. Subject as hereinafter provided, the Corporation further promises to pay interest on the principal amount of this Debenture from the date hereof at the rate of 4% per annum to and including the Final Instalment Date, following which date interest on the principal amount of this Debenture will be payable at the rate of 0%. The Corporation shall pay interest, while payable, quarterly in arrears in equal instalments on the first Business Day in March, June, September and December of each year (each an “Interest Payment Date”) until and including the Final Instalment Date (which shall be the final Interest Payment Date for this Debenture), commencing on March 3, 2014 (less any tax required by law to be deducted). Should the Corporation at any time make default in the payment of any principal or interest, the Corporation shall pay interest on the amount in default at the same rate, in like money and on the same dates. The first interest payment payable on March 3, 2014 shall be in the amount of $ 5.5890 per $1,000 principal amount of Debentures. If the Final Instalment Date occurs prior to the first anniversary of the date of this Indenture, the Corporation shall pay, on the Business Day following the Final Instalment Date, the Make-Whole Payment to Holders of record on the Final Instalment Date who have paid the Final Instalment on or before the Final Instalment Date. No Make-Whole Payment will be payable if the Final Instalment Date occurs on or after the first anniversary of the date of this Indenture.

The Corporation shall pay interest on this Debenture (except defaulted interest) to the person who is the Holder of this Debenture at the close of business on February 15, May 15, August 15 or November 15 (or on the next Business Day, if such date is not a Business Day), immediately preceding the related Interest Payment Date, or in the case of the Interest Payment Date occurring on the Final Instalment Date, the Final Instalment Date (each, a “Regular Record Date”). The Holder must surrender this Debenture to a Paying Agent to collect payment of principal. The Corporation will pay all amounts due and payable under this Debenture in the lawful currency of Canada. The Corporation may pay all amounts due and payable under this Debenture in respect of any Certificated Debenture by cheque or wire payable in such money; provided, however, that a Holder with a Debenture in an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election or direction of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the relevant payment date. The Corporation may mail an interest cheque to the Holder’s registered address. Notwithstanding the foregoing, so long as this Debenture is registered in the name of a Depository or its nominee, all payments hereon shall be

made by wire transfer of immediately available funds to the account of the Depository or its nominee.

This Debenture is one of a duly authorized issue of Debentures of the Corporation designated as its 4% Unsecured Subordinated Convertible Debentures due on January 9, 2024 issued under the Indenture. The terms of this Debenture include those stated in the Indenture and those required by or made part of the Indenture by reference to Indenture Legislation. This Debenture is subject to all such terms, and the Holder of this Debenture is referred to the Indenture and said legislation for a statement of them. In the event of any contradiction or inconsistency between the provisions of the Indenture and this Debenture, the provisions of the Indenture shall prevail.

The whole of the principal of this Debenture is convertible, at the option of the holder hereof and provided that the Final Instalment has been paid, upon surrender of this Debenture at the principal office of the Trustee in Toronto, Ontario, at any time on or after the Final Instalment Date and prior to the close of business on the Business Day immediately preceding the Maturity Date or, if this Debenture is called for redemption on or prior to such date, then up to but not after the close of business on the last Business Day immediately preceding the date specified for redemption of this Debenture, into Common Shares (without adjustment for interest accrued hereon or for dividends or distributions on Common Shares issuable upon conversion) at a conversion price of $30.72 (the “Conversion Price”) per Common Share, being a rate of approximately 32.5521 Common Shares for each $1,000 principal amount of Debentures, all subject to the terms and conditions and in the manner set forth in the Indenture. The Indenture makes provision for adjustment of the Conversion Rate and Conversion Price in the events therein specified, including without limitation, in the event of a stock split by the Corporation or payment of a dividend in kind. No fractional Common Shares will be issued on any conversion but in lieu thereof, the Corporation will satisfy such fractional interest by a cash payment equal to the fractional interest multiplied by the Conversion Price; provided, however, the Corporation shall not be required to make any payment of less than $10.00.

This Debenture may be redeemed after the Final Instalment Date at the option of the Corporation on the terms and conditions set out in the Indenture at the Redemption Price therein and herein set out and is otherwise not redeemable, except that this Debenture will be redeemed forthwith by the Corporation at the Redemption Price on the occurrence of any of the following prior to the Final Instalment Date: (a) notification to Holders that the Approval Conditions will not be satisfied; (b) termination of the Acquisition Agreement; or (c) July 2, 2015 if the Final Instalment Notice has not been given on or before June 30, 2015.

The Corporation may, on notice as provided in the Indenture, at its option and subject to any applicable regulatory approval and provided no Event of Default has occurred and is continuing, elect to satisfy the obligation to repay all or any portion of the principal amount of this Debenture due on the Maturity Date by the issue of that number of Common Shares obtained by dividing the principal amount of this Debenture to be paid for in Common Shares pursuant to the exercise by the Corporation of the Common Share repayment right by 95% of the Market Price on the Maturity Date.

The indebtedness evidenced by this Debenture, and by all other Debentures now or hereafter certified and delivered under the Indenture, is a direct unsecured obligation of the Corporation, and (i) will rank equally with one another and with all other unsecured and subordinated indebtedness of the Corporation except as prescribed by law and (ii) is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment of all Senior Indebtedness (including any indebtedness to trade creditors), whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed.

The principal hereof may become or be declared due and payable before the stated maturity in the events, in the manner, with the effect and at the times provided in the Indenture.

The Indenture or the Debentures may be amended or supplemented with the consent of the Holders of at least 662/3% in aggregate principal amount of the Debentures then outstanding (which consent may be obtained at a duly called and constituted meeting of Holders or by an instrument in writing), and an existing Default or Event of Default and its consequence or compliance with any provision of the Indenture or the Debentures may be waived in a particular instance with the consent of the Holders of 662/3% in aggregate principal amount of the Debentures then outstanding. Without the consent of or notice to any Holder, the Corporation and the Trustee may amend or supplement the Indenture or the Debentures to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of the Holders in any material respect.

This Debenture shall not be valid until the Trustee or an authenticating agent manually or by facsimile signs the certificate of authentication on this Debenture.

All terms defined in the Indenture and used in this Debenture but not specifically defined herein are defined in the Indenture and are used herein as so defined.

This Indenture and the Debenture shall be governed by, and construed in accordance with, the laws of the Province of Newfoundland and Labrador and the laws of Canada applicable therein. The Corporation has submitted to the non-exclusive jurisdiction of any court of the Province of Newfoundland and Labrador for purposes of all legal actions and proceedings instituted in connection with the Indenture and the Debentures.

The Corporation will furnish to any Holder, upon written request and without charge, a copy of the Indenture. Requests may be made to: Fortis Inc., The Fortis Building, Suite 1201, 139 Water Street, PO Box 8837, St. John’s, Newfoundland and Labrador, A1B 3T2 Attention: Corporate Secretary, Facsimile No: (709) 737-5307.
