Where this Indenture provides for notice to any Person in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the Regular Record Date for such interest, which shall be the 1st day (whether or not a business day) of the calendar month next preceding such Interest Payment Date. Except as otherwise provided in the Indenture, any such interest not so punctually paid

- 27 -

or duly provided for will forthwith cease to be payable to the registered Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities not less then 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner deemed practicable by the Trustee, all as more fully provided in the Indenture. Payment of the principal of and interest on this Security will be made in lawful money of Canada at any branch in Canada of The Royal Bank of Canada, or at such other place as may be designated by the Company for such purpose and approved by the Trustee. Payment of interest on this Security may be made at the option of the Company by warrant or cheque mailed to the address of the Person or Persons entitled thereto as such address shall appear on the Central Security Register.

This Security is one of a duly authorized issue of Securities of the Company designated as its 10% Debentures Due 2011 (herein called the “Securities”), limited in aggregate principal amount to $100,000,000, issued and to be issued under an indenture bearing formal date of April 15, 1987 (herein called the “Indenture”), between the Company and Compagnie Montréal Trust - Montreal Trust Company, Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Securities, and the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities will

- 28 -

be direct unsecured obligations of the Company and will rank pari passu with all other unsecured indebtedness of the Company.

All terms used in this Security which are defined in the Indenture shall have the respective meanings assigned to them in the Indenture except as otherwise expressly provided or unless the context otherwise requires.

The Securities will be redeemable, at the Company’s option, in whole at any time or in part from time to time, on not more than 60 and not less than 30 days prior notice, at the higher of the Canada Yield Price (as defined in the Indenture) and the principal amount thereof plus accrued and unpaid interest to the date fixed for redemption.

Where less than all of the outstanding Securities are to be redeemed, the Securities so to be redeemed will be selected by the Trustee in such a manner as it shall deem equitable.

The Company, commencing July 1, 1992, will make all reasonable efforts to purchase for cancellation in the open market during each three-month period, $1,125,000 principal amount of the Securities at prices not exceeding 100% of the principal amount thereof plus accrued and unpaid interest and costs of purchase. If in any three-month period, the Company is unable to purchase

- 29 -

such principal amount of Securities for any reason, trade below par, such purchase fund obligation for such period, to the extent unfulfilled, will be carried forward for the succeeding seven three-month periods and will thereafter be extinguished. The Securities which the Company is obligated to purchase during any three-month period pursuant to this provision will be reduced by the aggregate principal amount of the Securities redeemed or purchased by the Company in the same three-month period otherwise than pursuant to this provision.

If an Event of Default, as defined in the Indenture, shall occur, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon

- 30 -

all future Holders of this Security and of any Security issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security.

The Company may require payment of a sum sufficient to cover any tax or governmental charge or other reasonable charge payable in connection with any such transfer.

Le présent Titre est l’un des Titres d’une émission dûment autorisée de Titres de la Société désignés comme étant ses Débentures 10% échéant en 2011 (appelées dans les présentes “Titres”), dont le montant en capital global est limité à $100 000 000, et qui sont émis ou qui doivent être émis en vertu d’un contrat de fiducie portant la date officielle du 15 avril 1987 (appelé dans les présentes “contrat de fiducie”) et passé entre la Société et Compagnie Montréal Trust – Montreal Trust Company, à titre de fiduciaire (appelée dans les présentes “fiduciaire”, lequel terme comprend tout fiduciaire remplaçant aux termes du contrat de fiducie); il y a lieu de se reporter à ce contrat de fiducie et à tout contrat de fiducie supplémentaire pour obtenir l’énoncé des droits respectifs que possèdent en vertu de ceux-ci la Société, le fiduciaire et les détenteurs de Titres, de même que l’énoncé des conditions selon lesquelles les Titres sont et doivent être authentifiés et livrés. Les Titres constitueront des obligations non garanties directes de la Société et seront d’un rang égal à celui de toutes les dettes non garanties de la Société.

- 35 -

Tous les termes utilisés dans le présent Titre qui sont la version française de termes anglais ▇▇▇▇▇▇▇ dans la version anglaise du contrat de fiducíe ont le sens qui est attribué à ces termes anglais dans ladite version anglaise du contrat de fiducie, sauf si une disposition dans les présentes prévoit expressément le contraire ou si le contexte l’exige autrement.

Les Titres seront remboursables par anticipation, au gré de la Société, en totalité en tout temps ou en partie de temps à autre, sur préavis d’au plus 60 jours et d’au moins 30 jours, au plus élevé du Prix de rendement Canada (selon la définition de “Canada Yield Price” donnée dans la version anglaise du contrat de fiducie) et du montant en capital de ceux-ci plus les intérêts courus et impayés jusqu’à la date fixée pour le remboursement par anticipation.

Si moins de la totalité des Titres en circulation doivent être remboursés par anticipation, les Titres devant être ainsi remboursés seront choisis par le fiduciaire d’une manière qu’il jugera équitable.

La Société a également le droit d’acheter à des fins d’annulation les Titres sur le marché, par voie de soumission ou de gré à gré, à un prix n’excédant pas le prix auquel ces Titres sont, à la date d’achat, remboursables par anticipation plus dans chaque cas les intérêts courus et impayés à la date d’achat plus les frais d’achat. Les Titres achetés ou remboursés par anticipation par la Société sont annulés sans possibilité de réémission.

- 36 -

prix ne dépassant pas leur valeur nominale plus les intérêts courus et impayés et les frais d’achat. Si, au cours d’une période de trois mois quelconque, la Société est dans l’impossibilité d’acheter des Titres représentant ce montant en capital pour quelque raison que ce soit, notamment le fait que les Titres ne se sont pas négociés au-dessous du pair, cette obligation à l’égard du fonds d’achat quant à cette période, dans la mesure où elle n’aura pas été exécutée, sera reportée sur les sept périodes de trois mois subséquentes et s’éteindra par la suite. Le montant en capital global des Titres que la Société remboursera par anticipation ou achètera autrement que conformément à cet engagement pendant une période de trois mois quelconque réduira d’autant l’obligation d’achat de la Société conformément à cet engagement à l’égard de la période en question.

S’il survient un cas de défaut, selon la définition de “Event of Default” qui est donnée dans la version anglaise du contrat de fiducie, le capital de tous les Titres peut être déclaré dû et payable de la manière et avec l’effet prévus dans le contrat de fiducie.

- 37 -

comporte également des dispositions permettant aux détenteurs de pourcentages spécifiés du montant en capital global des Titres alors en circulation, au nom des détenteurs de tous les Titres, de renoncer à exiger que la Société se conforme à certaines dispositions du contrat de fiducie et du présent Titre, de renoncer à leurs recours à l’égard de certains cas de défaut antérieurs en vertu du contrat de fiducie et du présent Titre. Un tel consentement ou une telle renonciation de la part du détenteur du présent Titre sera concluant et 1iera ce détenteur et tous les détenteurs futurs du présent Titre et de tout Titre émis au moment du transfert du présent Titre ou en échange ou en remplacement de celui-ci, qu’un tel consentement ou qu’une telle renonciation soit ou non indiqué sur le présent Titre.

Comme il est prévu dans le contrat de fiducie et sous réserve de certaines restrictions qui y sont énoncées, le présent Titre nominatif est transférable par le détenteur inscrit dudit Titre; l’inscription du transfert se fait dans les registres des détenteurs de Titres de la Société, sur remise du présent Titre à des fins de transfert à l’un des principaux bureaux du fiduciaire dans les villes de Halifax, Saint-▇▇▇▇ (N.-B.), Montréal, Toronto, Winnipeg, ▇▇▇▇▇▇, Calgary et Vancouver; à cette fin, ledit Titre doit être dûment endossé par le détenteur inscrit dudit Titre ou par son fondé de pouvoir dûment autorisé par écrit, ou il doit être accompagné d’un instrument de transfert écrit dont le libellé est acceptable par la Société et par le fiduciaire ou tout agent chargé de la tenue d’un registre local des détenteurs de Titres, dûment signé par le détenteur du Titre ou par son fondé de pouvoir dûment autorisé par écrit. Sur ce, un ou plusieurs nouveaux Titres entièrement nominatifs sans coupons, en coupures autorisées et d’un montant en capital global équivalent, seront émis au ou aux cessionnaires

- 38 -

désignés. La Société peut exiger le paiement d’une somme suffisante pour couvrir toute taxe ou imposition gouvernementale ou tous autres frais raisonnables payables à l’égard d’un tel transfert.

La Société, le fiduciaire et tout autre mandataire de la Société ou du fiduciaire peuvent traiter la personne au nom de laquelle le présent Titre est immatriculé comme le propriétaire dudit Titre, et ce, à toutes fins, que le présent Titre soit ou non échu.

Les Titres sont émissibles sous forme de Titres à coupons, selon la définition de “Coupon Securities” qui est donnée dans la version anglaise du contrat de fiducie, immatriculables quant au capital, en coupures de $1 000, $5 000, $25 000 et $100 000, et sous forme de Titres entièrement nominatifs, sans coupons, en coupures de $1 000 et de multiples complets de $1 000. Le titre de propriété des Titres à coupons non immatriculés quant au capital et des coupons se rapportant à tout Titre est transmis sur livraison. Comme il est prévu dans le contrat de fiducie et sous réserve de certaines restrictions qui y sont énoncées, les Titres sont échangeables aux principaux bureaux du fiduciaire dans les villes mentionnées ci-dessus contre des Titres de nature ou de coupures différentes autorisées d’un montant en capital global équivalent, selon les instructions du détenteur remettant un tel Titre et, dans le cas de tout Titre à coupons, tous les coupons non échus et tous les coupons échus en souffrance s’y rapportant, sur paiement des taxes et des impositions gouvernementales et des autres frais raisonnables.

A moins que l’attestation d’authenticité apparaissant sur les présentes n’ait été signée par le fiduciaire par le biais de la signature manuscrite de l’un de ses dirigeants autorisés, le

- 39 -

présent Titre ne donne droit à aucun avantage en vertu du contrat de fiducie et il n’est ni valide ni obligatoire à quelque fin que ce soit.

Si, au cours d’une période de trois mois quelconque, la Société est dans l’impossibilité d’acheter des Titres représéntant ce montant en capital pour quelque raison que ce soit, notamment le fait que les Titres ne se sont pas négociés au-dessous du pair, cette obligation à l’égard du fonds d’achat quant à cette période, dans la mesure où elle n’aura pas été exécutée, sera reportée sur les sept périodes de trois mois subséquentes et s’éteindra

- 49 -

par la suite. Le montant en capital global des Titres que la Société remboursera par anticipation ou achètera autrement que conformément à cet engagement pendant une période de trois mois quelconque réduira d’autant l’obligation d’achat de la Société conformément à cet engagement à l’égard de la période en question.

Le contrat de fiducie permet, à quelques exceptions près qui y sont prévues, la modification en tout temps par la Société dudit contrat de fiducie, de même que des droits et des obligations de la Société et des droits des détenteurs des Titres et des coupons, en vertu du contrat de fiducie, avec le consentement des détenteurs des deux tiers du montant en capital global des Titres alors en circulation, selon la définition de “Outstanding” qui est donnée dans la version anglaise du contrat de fiducie, ou des détenteurs d’un pourcentage inférieur de ce montant en capital global ayant agi à une réunion des détenteurs de Titres dûment tenue conformément aux dispositions du contrat de fiducie. Le contrat de fiducie comporte également des dispositions permettant aux détenteurs de pourcentages spécifiés du montant en capital global des Titres alors en circulation, au nom des détenteurs de tous les Titres, de renoncer à exiger que la Société se conforme à certaines dispositions du contrat de fiducie et du présent Titre et de renoncer à leurs recours a l’égard de certains cas de défaut antérieurs en vertu du contrat de fiducie et du présent Titre. Un tel consentement ou une telle renonciation de la part du détenteur du présent Titre sera concluant et

- 50 -

▇▇▇▇▇ ▇▇ détenteur et tous les détenteurs futurs du présent Titre et de tout Titre émis en échange ou en remplacement de celui-ci, qu’un tel consentement ou qu’une telle renonciation soit ou non indiqué sur le présent Titre.

Le présent Titre est transférable sur livraison, à moins qu’il ne soit immatriculé quant au capital au nom du détenteur dans le registre central des détenteurs de Titres de la Société. Le présent Titre peut être ainsi immatriculé sur présentation des présentes à l’un des principaux bureaux du fiduciaire dans les villes de Halifax, Saint-▇▇▇▇ (N.-B.), Montréal, Toronto, Winnipeg, ▇▇▇▇▇▇, Calgary et Vancouver, cette immatriculation étant notée sur les présentes. Tant que le présent Titre est immatriculé de la façon susmentionnée, il est transférable par le détenteur inscrit des présentes et l’inscription d’un tel transfert se fait dans les registres des détenteurs de Titres de la Société sur présentation, comme il est indiqué ci-dessus, du présent Titre aux fins d’y noter un tel transfert, accompagné d’un instrument de transfert écrit dont le libellé est acceptable par la Société et par le fiduciaire ou tout agent chargé de la tenue d’un registre local des détenteurs de Titres, dûment signé par le détenteur inscrit des présentes ou par son fondé de pouvoir dûment autorisé par écrit, le tout tel qu’il est prévu dans le contrat de fiducie et sous réserve de certaines restrictions qui y sont énoncées; cependant, le présent Titre peut être dispensé d’immatriculation s’il est transféré au porteur de la manière indiquée ci-dessus, et, sur ce, la transférabilité sur livraison est rétablie. Le présent Titre continue d’être soumis aux immatriculations et aux transferts successifs au porteur au gré du porteur ou du détenteur inscrit, selon le cas. Cette immatriculation, cependant, ne porte aucunement atteinte à la transférabilité sur livraison des coupons s’attachant au présent Titre,

- 51 -

lesquels continueront d’être payables au porteur et transférables sur livraison. La Société peut exiger le paiement d’une somme suffisante pour couvrir toute taxe ou imposition gouvernementale ou tous autres frais raisonnables payables à l’égard d’une telle immatriculation, d’un tel transfert ou d’une telle dispense d’immatriculation.

La Société, le fiduciaire et tout autre mandataire de la Société ou du fiduciaire peuvent traiter le porteur du présent Titre ou, si le présent Titre est immatriculé comme il est autorisé dans les présentes, la personne au nom de laquelle le présent Titre est immatriculé et le porteur de tout coupon s’y rattachant comme le propriétaire dudit Titre et dudit coupon, et ce, à toutes fins, que le présent Titre soit ou non échu.

Les Titres sont émissibles sous forme de Titres à coupons, selon la définition de “Coupon Securities” qui est donnée dans la version anglaise du contrat de fiducie, immatriculables quant au capital, en coupures de $ 1 000, $ 5 000, $ 25 000 et $ 100 000 et sous forme de Titres entièrement nominatifs, sans coupons, en coupures de $ 1 000 et de multiples complets de $ 1 000. Comme il est prévu dans le contrat de fiducie et sous réserve de certaines restrictions qui y sont énoncées, les Titres sont échangeables aux principaux bureaux du fiduciaire dans les villes mentionnées ci-dessus contre des Titres de nature ou de coupures différentes autorisées d’un montant en capital global équivalent, selon les instructions du détenteur remettant un tel Titre et, dans le cas de tout Titre à coupons, tous les coupons non échus et tous les coupons échus en souffrance s’y rapportant, sur paiement des taxes et des impositions gouvernementales et des autres frais raisonnables.

A moins que 1’attestation d’authenticité apparaissant sur les présentes n’ait été signée par

- 52 -

le fiduciaire par le biais de la signature manuscrite de l’un de ses dirigeants autorisés, ni le présent Titre ni aucun coupon s’y rattachant donnent droit à aucun avantage en vertu du contrat de fiducie et ils ne sont ni valides ni obligatoires à quelque fin que ce soit.

EN FOI DE QUOI, la Société a fait signer le présent Titre par ses dirigeants dûment autorisés et a fait joindre aux présentes des coupons portant la signature en fac-similé de son trésorier.

ARTICLE THREE

The Securities

Section 301. Title and Terms.

The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $100,000,000, except for Securities authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Securities pursuant to Sections 304, 305, 306, 805 or 1108.

The Securities shall be known and designated as the “10% DEBENTURES DUE 2011” of the Company. Their Stated Maturity shall be April 15, 2011 and they shall bear interest from the later of April 15, 1987 and the most recent Interest Payment Date to which interest has been paid or duly provided for, payable semi-annually in arrears on April 15

- 54 -

and October 15 in each year commencing on October 15, 1987, at the rate of 10% per annum until the principal thereof is paid or made available for payment, as more fully described in the forms of Securities set forth in Sections 202 and 203 of this Indenture.

The principal of and interest on the Securities shall be payable at any branch in Canada of The Royal Bank of Canada, or at such other place as may be designated by the Company for such purpose and approved by the Trustee (any municipality in which any such branch or place is located being herein called a “Place of Payment”).

The Regular Record Date referred to in Section 307 for the payment of the interest payable and punctually paid or duly provided for on any Interest Payment Date in respect of Fully Registered Securities shall be the 1st day (whether or not a business day) of the calendar month next preceding said Interest Payment Date.

The Securities shall be redeemable as provided in Article Eleven.

Section 302. Denominations.

The Securities may be issued as Coupon Securities in the denominations of $1,000, $5,000, $25,000 and $100,000 and as Fully Registered Securities in denominations of $1,000 and integral multiples thereof.

- 55 -

Section 303. Execution, Authentication Delivery and Dating.

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Vice-Presidents and by its Secretary or one of its Assistant Secretaries. Any such signature may be manual or printed or otherwise mechanically reproduced and may, but need not be, under or accompanied by the corporate seal of the Company or a reproduction thereof. The coupons shall bear the printed or otherwise mechanically reproduced signature of the Treasurer or an Assistant Treasurer of the Company.

Securities and coupons appertaining thereto bearing the printed or otherwise mechanically reproduced signatures of any Person who was at any time the proper officer of the Company shall bind the Company, notwithstanding that such Person has ceased to hold such office prior to the authentication and delivery of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

Each Security shall be dated the date of its authentication.

No Security or coupon appertaining thereto shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the

- 56 -

form provided for herein executed by the Trustee by the manual signature of one of its authorized officers, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Subject to the provisions of Section 305 and except as permitted by Section 306, the Trustee shall not authenticate and deliver any Coupon Security unless all appurtenant coupons for interest then matured have been detached and cancelled.

The definitive Securities and coupons shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner not contrary to the rules of any securities exchange on which the Securities may at the time be listed, all as determined by the officers executing such Securities, as evidenced by their signing of such Securities.

Section 304. Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in bearer or registered form, with one or more coupons or without coupons, with or without provision for registration as to principal and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their signing of such Securities.

- 57 -

If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any Place of Registration, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities (accompanied by any unmatured coupons appertaining thereto) the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized form and denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and interest thereon, when and as payable, shall be paid to the bearers of temporary Securities upon presentation thereof for notation of such payment thereon, unless such temporary Securities shall be Fully Registered Securities or shall bear coupons for such interest.

Section 305. Registration, Registration of Transfer and Exchange.

The Company shall cause to be kept by the Trustee at its principal office in the City of Montreal (or at such other Place of Registration in Canada maintained by the Trustee as may be requested by the Company with the approval of the Trustee) a central Security register (herein referred to as the “Central Security Register”) and at each other Place of Registration, a branch Security register (herein collectively referred to as the “Branch Security Registers” and the Branch Security Registers together with the Central Security Register are herein sometimes collectively referred to as the “Security Registers”) in which,

- 58 -

subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and the registration of transfers of Registered Securities entitled to be registered or transferred as herein provided. A Branch Security Register shall at least contain particulars of the registration of Securities and the registration of transfers of Registered Securities made at the Place of Registration where such Branch Security Register is being maintained and the Central Security Register shall contain particulars of registrations of Securities and registrations of transfers of Registered Securities made at all Places of Registration. The Trustee is hereby appointed registrar for the purpose of registering Securities and transfers of Registered Securities as herein provided on the Central Security Register and a “Branch Security Registrar” for the purpose of registring Securities and transfers of Registered Securities as herein provided on the Branch Security Registers expressly provided for on the date hereof. Each Branch Security Registrar (if other than the Trustee) shall provide the Trustee with the particulars of each registration of Securities and of transfers of Registered Securities made on the Branch Security Register for which it has been appointed Branch Security Registrar immediately following any such registration.

Any office or agency appointed pursuant to Section 1002 after the date hereof shall, by its appointment as such, also be deemed to have been appointed a “Branch Security Registrar” for the purpose of registering Securities and transfers of Registered Securities as herein provided on the Branch Security Register for which it has been appointed Branch Security Registrar.

Upon surrender for transfer of any Fully Registered Security at any Place of Registration,

- 59 -

the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Fully Registered Securities of a like aggregate principal amount, all as requested by the transferor.

Upon presentation for registration of any Coupon Security at any Place of Registration, the Security shall be registered as to principal in the name of the Holder thereof and such registration shall be noted on the Security. Any Coupon Security so registered shall be transferable on the Security Registers, upon presentation of such Security at any Place of Registration for similar notation thereon, but such Security may be discharged from registration by being in like manner transferred to bearer, whereupon trans-ferability by delivery shall be restored. Coupon Securities shall continue to be subject to successive registrations and discharges from registration at the option of the Holders thereof. Each such registration or discharge shall be subject to payment, if the Company shall so require, of the charges hereinafter provided.

The Coupon Securities shall be transferable by delivery except while registered as to principal. Registration of any Coupon Security shall not affect the transferability by delivery of the coupons appertaining thereto, which shall continue to be payable to bearer and transferable by delivery.

At the option of the Holder, Coupon Securities may be exchanged for Coupon Securities in any other authorized denominations or for Fully Registered Securities of any authorized denominations, of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Place of Registration with all unmatured coupons and all matured coupons in default thereto appertaining,

- 60 -

and upon payment, if the Company shall so require, of the charges hereinafter provided. If the Holder of a Coupon Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, such exchange may be effected if the Coupon Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons or the surrender of such missing coupon or coupons may be waived by the Company, and the Trustee, if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment. Notwithstanding the foregoing, in case a Coupon Security is surrendered in exchange for a Fully Registered Security at any Place of Registration after the close of business at such Place of Registration on (i) any Regular Record Date and before the opening of business at such Place of Registration on the next succeeding Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such Place of Registration on the related proposed date for payment of Defaulted Interest, such Coupon Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date of payment, as the case may be.

At the option of the Holder, Fully Registered Securities may be exchanged for Coupon Securities or Fully Registered Securities of any authorized denominations, of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Place of Registration and upon payment, if the Company shall so require, of the charges hereinafter provided. In case a Fully

- 61 -

Registered Security is surrendered in exchange for a Coupon Security at any Place of Registration after the close of business at such Place of Registration on (i) any Regular Record Date and before the opening of business at such Place of Registration on the next succeeding Interest Payment Date or (ii) any Special Record Date and before the opening of business at such Place of Registration on the related proposed date for payment of Defaulted Interest, there shall be detached from the Coupon Security issued on such exchange the coupon relating to such Interest Payment Date or proposed date of payment of Defaulted Interest and interest will not be paid on such Interest Payment Date or proposed date for payment of Defaulted Interest in respect of the Coupon Security issued in exchange for such Fully Registered Security but will be payable only to the Person in whose name that Fully Registered Security (or one or more Predecessor Securities) is registered at the close of business on such regular or special Record Date.

Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Securityholder making the exchange is entitled to receive.

Every Registered Security presented or surrendered for registration of transfer, shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Trustee or other Branch Security Registrar, if any, duly executed, by the Holder thereof or his attorney duly authorized in writing.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the

- 62 -

same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

The Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Securities and in addition a reasonable service charge for the services rendered and expenses incurred on any such exchange or transfer, except in the case of any transfer or exchange, expressly provided in this Indenture to be made at the Company’s own expense or without expense or without charge to Securityholders.

All Securities and coupons surrendered upon any exchange or transfer provided for in this Indenture shall be promptly cancelled by the Trustee and thereafter disposed of as directed by a Company Order.

The Company shall not be required (i) to issue, register the transfer of or exchange any Security during a period beginning at the opening of business 15 days before the date of any selection of Securities to be redeemed and ending at the close of business on the day of the first publication, or the mailing (if there is no publication) of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security or any Security with a mutilated coupon appertaining to it is surrendered to the Trustee, the Company shall execute and the Trustee shall thereupon authenticate and deliver in exchange therefor a new Security of like

- 63 -

tenor and principal amount, bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.

If there be delivered to the Company and to the Trustee

(i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon, and

(ii) such security or indemnity as may be required by them to save each of them and any agent of each of them harmless,

then, in the absence of notice to the Company or the Trustee that such Security or coupon has been acquired by a bona fide purchaser, the Company shall execute and upon its request (in the form of a Company Request) the Trustee shall authenticate and deliver in lieu of any such destroyed, lost or stolen Security, or in exchange for the Security to which such coupon appertains (upon surrender of such Security with all appurtenant coupons not destroyed, lost or stolen), a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains.

In case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or coupon.

Upon the issuance of any new Security under this Section, the Company may require the payment

- 64 -

of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security and every new coupon issued pursuant to this Section in lieu of any destroyed, lost or stolen coupon, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost or stolen coupon, shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities and coupons duly issued hereunder.

The provisions of this Section are 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 Securities or coupons.

Section 307. Payment of Interest; Interest Rights Preserved.

Interest on any Fully Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. In case a Coupon Security is surrendered in exchange for a Fully Registered Security at any Place of Registration after the close of business at such Place of Registration on (i) any Regular Record Date and before the opening of business at such Place of Registration on

- 65 -

the next succeeding Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such Place of Registration on the related proposed date for payment of Defaulted Interest, such Coupon Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date of payment and interest will not be payable on such Interest Payment Date or proposed date of payment in respect of the Fully Registered Security issued in exchange for such Coupon Security, but will be payable only to the Holder of such coupon.

Any Defaulted Interest on any Fully Registered Security shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, either as provided in Clause (1) or in Clause (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Fully Registered Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner: the Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Fully Registered Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to

- 66 -

such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given, to each Holder of Fully Registered Securities not less than 10 days nor more than 15 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Fully Registered Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner and upon such notice to the Securityholders if, after notice given by the Company to the Trustee of the proposed payment and the manner and notice thereof, such manner of payment and such notice shall be deemed appropriate by the Trustee.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

- 67 -

Section 308. Persons Deemed Owners.

The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Unregistered Security and the bearer of any coupon, whether or not the Security to which it appertains be registered, as the owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes, whether or not such Security or coupon be overdue. Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of, and (subject to Section 307) if such Security be a Fully Registered Security, interest on, such Security and for all other purposes whatsoever (except the payment of coupons appertaining to any Registered Coupon Security and the payment of interest payable on presentation of any temporary Security) whether or not such Security be overdue.

Section 309. Cancellation and Disposal of Securities

All Securities and coupons surrendered for payment, exchange or redemption shall, if surrendered to the Company or any agent of the Company, be delivered to the Trustee and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder, together with all

- 68 -

unpaid coupons appertaining thereto, which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities and coupons held by the Trustee shall be disposed of as directed by a Company Order.

Section 310. Authentication and Delivery of Original Issue.

Forthwith upon the execution and delivery of this Indenture, or from time to time thereafter, Securities up to the aggregate principal amount provided for in Section 301 may be executed by the Company and delivered to the Trustee for authentication, and shall thereupon be authenticated and delivered by the Trustee upon Company Order, without any further action by the Company.

ARTICLE FIVE

Section 502. Acceleration of Maturity; Rescission and Annulment.

If an Event of Default occurs and is continuing, then and in every such case the Trustee may, in its discretion and shall, if so requested by the Holders of not less than 25% in principal amount of the Securities Outstanding declare the principal of all the Securities to be due and payable immediately, by a notice in writing to the Company, and upon any such declaration such principal shall become immediately due and payable.

At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Securityholders may by a Majority Securityholders’ Act delivered to the Company and the Trustee rescind and annul such declaration and its consequences if

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay

(A) all overdue instalments of interest on all Securities,

- 75 -

(B) the principal of any Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Securities,

(C) to the extent that payment of such interest is lawful, interest upon overdue instalments of interest at the rate borne by the Securities, and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;

and

(2) all Events of Default, other than the non-payment of the principal of Securities which has become due solely by such acceleration, have been cured or waived as provided in Section 512.

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

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if

(1) default is made in the payment of any instalment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days _t or

- 76 -

(2) default is made in the payment of the principal of any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities and coupons, the whole amount then due and payable on such Securities and coupons for principal and interest, with interest upon the overdue principal and, to the extent that payment of such interest shall be legally enforceable, upon overdue instalments of interest, at the rate borne by the Securities; and in addition thereto, 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.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name on behalf of all the Holders of Securities and the coupons and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon the Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or of any other obligor upon the Securities, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of the Securities and the coupons by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this

Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 504. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and the coupons and to file such 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 of the Holders of the Securities and coupons allowed in such judicial proceeding, and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

- 78 -

and any receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Securityholder to make such payments to the Trustee, and if the Trustee shall so consent, to the making of such payments directly to the Holders of the Securities and coupons, 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 606.

Subject to Article Seven and Section 802, nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or a coupon any plan or reorganization, arrangement, adjustment or composition affecting the Securities or the coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any such Holder in any such proceeding.

- 79 -

Section 506. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 606; and

SECOND: To the payment of the amount then due and unpaid upon the Securities and coupons for principal and interest, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities and coupons, for principal and interest, respectively.

Section 507. Limitation on Suits.

No Holder of any Security or coupon shall have any right to institute against the Company or any other obligor upon the Securities any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

- 81 -

Section 508. Restoration of Rights and Remedies.

If the Trustee or any Holder of a Security or a coupon has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder then and in every such case the Company, the Trustee and the Holders of such Securities and coupons shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and such Holders shall continue as though no such proceeding had been instituted.

Section 509. Rights and Remedies Cumulative.

Except as provided in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 510. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default

- 82 -

shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

The Securityholders, by way of a Majority Securityholders’ Act, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that

The Securityholders, by way of a Majority Securityholders’ Act, may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default in respect of a covenant or provision hereof which under Article Eight cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

- 83 -

Upon any such waiver, such default shall cease to exist, and any Event of Default arising from such default shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 513. Undertaking for Costs.

All parties to this Indenture agree, and each Holder of any Security or coupon by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee or to any suit instituted by any Securityholder, or group of Securityholders, holding more than 10% in principal amount of the Outstanding Securities.

When determining any ratio between Consolidated Net Tangible Assets and the principal amount of Consolidated Funded Debt, such determination shall be made by the Board of Directors (who may determine such Consolidated Net Tangible Assets to be not less than a stated amount without determining the exact amount thereof), on the basis of the most recent financial statements or financial data made available to the Board of Directors, as at a date not more than 120 days prior to the date of the adoption of the resolution of the Board of Directors

- 119 -

authorizing the issue of the Funded Debt in respect of which such ratio is being determined, and there shall be taken into calculation all issues and retirements of Funded Debt (without duplication) and of shares of capital stock and the proceeds of such issues and the expenditures on such retirements made and received and to be made and received, as the case may be, and such change in the value of Consolidated Net Tangible Assets as the Board of Directors shall deem material, subsequent to the date as of which such determination is being made up to and including the date of the first delivery of any of the Funded Debt authorized by such resolution and including all the other Funded Debt which have been authorized for issue by said resolution and the estimated net proceeds to be received on the issue of such other Funded Debt;

(2)

when determining any ratio between Exempted Debt and Consolidated Net Tangible Assets, such determination (which may stipulate such Consolidated Net Tangible Assets to be not less than a stated amount without stipulating the exact amount thereof) shall be made by a financial officer of the Company, on the basis of the most recent available financial statements or financial data, as at a date not more than one hundred and twenty (120) days prior to the date on which the Exempted Debt in respect of which such ratio is being determined is to be incurred or, in the case of an Attributable Obligation, the date on which the Sale and Leaseback Transaction is to be entered into, and there shall be

- 120 -

taken into calculation all issues and retirements of Funded Debt and Exempted Debt (without duplication) and of shares of capital stock and the proceeds of such issues and the expenditures on such retirements made and received, as the case may be, and such change in the value of Consolidated Net Tangible Assets as shall be deemed material, subsequent to the date as of which such determination is being made up to and including the first date on which any of the Exempted Debt in respect of which such determination is being made is to be incurred or entered into and including all the other Exempted Debt which have been concurrently authorized for issue and the estimated net proceeds to be received on the issue of such other Exempted Debt;

(3)

there shall be excluded from such calculations all Exempted Debt and Funded Debt of the Company payable to a Restricted Subsidiary or of any Restricted Subsidiary payable to the Company or to any other Restricted Subsidiary; and

(4)

all such calculations and determinations shall be made in accordance with generally accepted accounting principles.

Section 1016. Purchase Fund.

In each calendar quarter commencing with the quarter beginning on July 1, 1992, the Company will make all reasonable efforts to purchase in the open market in Canada, at such time or times as the Company in its discretion shall determine, at a price or prices not exceeding in each case the principal

- 121 -

amount thereof plus accrued and unpaid interest and costs of purchase, up to $1,125,000 principal amount of the Securities which Securities (together with all unmatured coupons, if any, appertaining thereto) so purchased shall be promptly surrendered by the Company to the Trustee for cancellation.

If in any such calendar quarter the Company shall, for any reason, including the fact that the Securities did not trade at or below the aforesaid maximum price, be unable, by the exercise of all reasonable efforts, to purchase as aforesaid, the maximum principal amount of Securities which it is obliged by this Section 1016 to endeavour to purchase during such quarter, then the Company shall not be in default hereunder, but in each such case the maximum principal amount of the Securities which it shall be obliged to make all reasonable efforts to purchase as aforesaid during the next succeeding calendar quarters shall be increased by that amount which is equal to the difference between the maximum principal amount of Securities which the Company was obliged to endeavour to purchase during such first mentioned quarter and the principal amount of Securities actually purchased during such first mentioned quarter in discharge of that obligation.

Provided that:

(a) If during any calendar quarter the obligation of the Company to endeavour to purchase Securities under this Section 1016 is in excess of $1,125,000 as aforesaid, then the principal amount of Securities purchased hereunder during such calendar quarter shall be deemed to be applied first in reduction of such excess, and if the principal amount so purchased is insufficient to discharge fully the obligation with respect to the entire such excess, it shall be deemed to be applied to the discharge of the respective amounts

- 122 -

thereof arising in respect of each of the preceding calendar quarters in the order of their respective dates, beginning with the earliest such quarter;

(b) Where an obligation to endeavour to purchase Securities has been initially incurred in respect of any calendar quarter and during the next seven succeeding calendar quarters has not been deemed to have been fully discharged by virtue of subsequent purchases of Securities determined as aforesaid, then the amount of the aggregate obligation of the Company in respect of the eighth succeeding calendar quarter shall be deemed to have been reduced by an amount equal to the remaining undischarged amount of such first mentioned obligation; and

(c) The Company may, in the discharge of its obligation under this Section 1016 in respect of any calendar quarter, surrender to the Trustee in respect of that quarter, Securities (together with all unmatured coupons, if any, appertaining thereto) which may have been redeemed or purchased by it during such quarter otherwise than pursuant to such obligation, and upon any such surrender, the principal amount of the Securities which the Company is by this Section obliged to endeavour to purchase during such calendar quarter shall be deemed to have been reduced by an amount equal to the aggregate principal amount of the Securities so surrendered.

Section 1017. Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any covenant or condition set forth in this Article Ten, if before or after the time for such compliance the Securityholders shall, by a Majority Securityholders’ Act, either waive such compliance in such instance or generally

- 123 -

waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect.

The Securities will be redeemable, at the Company’s option, in whole at any time or in part from time to time, on not more than 60 and not less than 30 days prior notice at the higher of the Canada Yield Price (as defined below) and 100% of the principal amount thereof, together in each case with accrued and unpaid interest to the date fixed for redemption.

“Canada Yield Price” shall mean, in effect, a price equal to the price of the Securities calculated to provide a yield to maturity equal to the Government of Canada Yield plus 0.50% on the business day preceding the date of the resolution authorizing the redemption or if such price is being calculated for the purpose of Section 1109, on the business day preceding the date of purchase. “Government of Canada Yield” on any date shall mean, in effect, the yield to maturity on such date compounded semi-annually which a non-callable Government of Canada Bond would carry if issued, in Canadian dollars in Canada, at 100% of its principal amount on such date with a term to maturity equal to the remaining term to maturity of the

- 124 -

Securities. The Government of Canada Yield will be provided by two Canadian investment dealers, Wood Gundy Inc. and ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ Inc., or such other Canadian investment dealer or dealers as the Company may determine from time to time and as may be acceptable to the Trustee.

Section 1102. Applicability of Article.

Redemption of Securities by the Company shall be made in accordance with this Article.

Section 1103. Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all of the Securities, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee) notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed.

Section 1104. Selection by Trustee of Securities to be Redeemed.

If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities not previously called for redemption by such method as it shall deem equitable and which may provide for the selection for redemption of portions (equal to $1,000 or a multiple thereof) of the principal of Securities of a denomination larger than $1,000.

- 125 -

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security which has been or is to be redeemed only in part, to the portion of the principal of such Security which has been or is to be redeemed.

Section 1105. Notice of Redemption.

Notice of the proposed redemption shall be given in the manner provided in this Indenture to each Holder of Securities to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date; provided that where any such notice is being given to the Holders of Unregistered Securities, the same shall be published in an Authorized Newspaper in each of the Cities of Montreal and Toronto once in each of 4 successive calendar weeks, the first publication to be not less than 30 nor more than 60 days prior to the Redemption Date.

If notice is published as aforesaid, neither failure to give notice by mail, nor defect in any notice so mailed, shall affect the validity of the proceedings for such redemption.

- 126 -

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all Outstanding Securities are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the Securities to be redeemed,

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security, and that interest thereon shall cease to accrue on and after said date, and

(5) the place where such Securities are to be surrendered for payment of the Redemption Price.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name of and at the expense of the Company.

Section 1106. Deposit of Redemption Price.

At least one business day prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of all the Securities which are to be redeemed on such Redemption Date.

- 127 -

Section 1107. Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified and on and after such date (unless the Company shall default in the payment of the Redemption Price) such Securities shall cease to bear interest and all coupons appertaining to such Securities which represent instalments of interest to become due after the Redemption Date shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price together with accrued interest to the Redemption Date, provided, however, that instalments of interest on Coupon Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only upon presentation and surrender of coupons for such interest and provided, further, that instalments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 307. Interest maturing on or prior to the Redemption Date shall continue to be payable (but without interest thereon, unless the Company shall default in the due payment or provision for payment thereof) in the case of Coupon Securities to the bearers of the coupons for such interest upon surrender thereof, and in the case of Fully Registered Securities to the Registered Holders thereof according to their terms in the customary manner.

- 128 -

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate borne by such Security.

If any Coupon Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee, if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted.

Section 1108. Securities Redeemed in Part.

Any Security which is to be redeemed only in part may, at the option of the Holder,

(1) be presented to the Trustee or Paying Agent for notation thereon of the payment as of the Redemption Date of the redeemed portion of the principal thereof, or

(2) be surrendered (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee

- 129 -

shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination or denominations as requested by such Holder in aggregate principal amount equal to the unredeemed portion of the principal of the Security so surrendered.

Section 1109. Purchase of Securities

At any time when the Company is not in default hereunder it may purchase for cancellation all or any Securities in the market or by tender or by private contract, provided that the prices at which such Securities may be purchased shall not exceed the Redemption Price (including accrued interest) at which such Securities could, at the time of purchase, be redeemed by the Company at its option, plus costs of purchase. All Securities so purchased shall be delivered to the Trustee and shall be cancelled by it and no Securities shall be issued in substitution therefor.
