 i) such notice shall be sufficiently given to Holders of Unregistered Securities if advertised once in an Authorized Newspaper in the City of Montreal and the City of
Toronto on a business day which is not earlier than the earliest date nor later than the latest date prescribed for the giving of such notice; and 
 ii)
such notice shall be sufficiently given to any Holder of Registered Securities if in writing and mailed, first-class postage prepaid, to such Registered Holder of such Central Security, at his address as it appears on the Central Security Register,
not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. 
 In any case where notice
to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice by publication to Holders of Unregistered Securities given as provided above. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by first-class postage prepaid mail, then such notification to Holders of
Registered Securities as shall be made with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder.

 In case, by reason of the suspension of publication of any Authorized Newspaper, or by reason of any
other cause, it shall be impracticable to make publication of any notice in an Authorized Newspaper or Authorized Newspapers as required by this Indenture, then such method of publication or notification as shall be made with the approval of the
Trustee shall constitute a sufficient publication of such notice for every purpose hereunder. 
 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. Waivers of notice by Securityholders shall be
filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

1987 (each such date being an “Interest Payment Date”), at the rate of 10% per annum. 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)

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

 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 shall also have the right to purchase for cancellation
the Securities in the market, by tender or private contract, at prices not exceeding the price at which such Securities are redeemable, at the date of purchase, plus in each case accrued and unpaid interest to the date of purchase and costs of
purchase. The Securities purchased or redeemed by the Company shall be cancelled and shall not be reissued. 
 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. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities and coupons under the Indenture at any time by the Company with the consent of the Holders of two-thirds in aggregate principal amount of the Securities at the time Outstanding, as defined in
the Indenture, or of such lesser amount thereof as shall have acted at a meeting of the Holders of the Securities duly held pursuant to the provisions of the Indenture. The Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and of this Security and certain past
defaults under the Indenture and under this Security and their consequences. 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. 
 As provided in the Indenture and subject to certain limitations therein set forth, this
Registered Security is transferable by the registered Holder hereof on the Security Registers of the Company, upon surrender of this Security for transfer at the principal office of the Trustee in the Cities of Halifax, Saint John, Montreal,
Toronto, Winnipeg, Regina, Calgary and Vancouver, duly endorsed by, or 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 Registered
Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Fully Registered Securities without coupons, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee
or transferees. 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. 
 The Company, the Trustee and any agent of the Company or of the Trustee may treat the Person in whose name this Security is registered as the owner
hereof for all purposes whether or not this Security be overdue. 
 The Securities are issuable as Coupon Securities, as defined in the
Indenture, registrable as to principal, in the denominations of $1,000, $5,000, $25,000 and $100,000 and as fully registered Securities without coupons in denominations of $1,000 and any integral multiple thereof. Title to Coupon Securities not
registered as to principal, 

  

 - 31 - 

 
and to coupons appertaining to any Security shall pass by delivery. As provided in the Indenture and subject to certain limitations therein set forth,
Securities are exchangeable at the principal office of the Trustee in the Cities above mentioned for a like aggregate principal amount of Securities of a different authorized kind or denomination, as requested by the Holder surrendering the same
with, in the case of any Coupon Security, all unmatured coupons and all matured coupons in default thereto appertaining, upon payment of taxes and governmental charges and other reasonable charges. 
 Unless the certificate of authentication hereon has been executed by the Trustee by the manual signature of one of its authorized officers, this Security
shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

 IN WITNESS WHEREOF, the Company has caused this Security to be executed by its duly authorized officers.

DOLLARS et de payer les intérêts s’y rapportant à compter du 15 avril 1987 ou à compter de la dernière date de paiement des intérêts à l’égard de laquelle des
intérêts ont été versés ou dûment mis de côté, selon celle de ces dates qui tombera la dernière, et ce, semestriellement terme échu le 15 avril et le 15 octobre de chaque
année à compter du 15 octobre 1987 (chacune de ces dates étant une “date de paiement des intérêts”), au taux annuel de 10%. Les intérêts ainsi payables, qui sont payés ponctuellement ou
dûment mis de côté, à toute date de paiement des intérêts seront, tel qu’il est prévu dans le contrat de fiducie, versés à la personne au nom de laquelle le présent Titre (ou un
ou plusieurs Titres remplacés, selon la définition de “Predecessor Securities” qui est donnée dans la version anglaise dudit contrat de fiducie) est immatriculé à la fermeture des bureaux à la date
ordinaire de clôture des registres se rapportant à ces intérêts, laquelle est le ler jour (qu’il s’agisse ou non d’un jour ouvrable) du mois civil précédant cette date de paiement des
intérêts. Sauf dans la mesure où il est prévu autrement dans le contrat de fiducie, les intérêts qui ne sont pas ainsi payés ponctuellement ou dûment mis de côté cesseront
aussitôt d’être payables au détenteur inscrit à cette date ordinaire de clôture des registres et ils peuvent soit être payés à la personne au nom de laquelle le présent Titre (ou un ou
plusieurs Titres remplacés) est immatriculé à la fermeture des bureaux à une date spéciale de clôture des registres à l’égard du paiement de ces intérêts en souffrance qui doit
être fixée par le fiduciaire, un avis à cet égard devant être donné aux détenteurs de Titres au moins dix jours avant cette date spéciale de clôture des registres, soit être
payés en tout temps de toute autre manière licite que le fiduciaire juge possible, le tout tel qu’il est prévu plus en détail dans le contrat de fiducie. Le paiement du capital et des intérêts sur le
présent Titre sera effectué en monnaie légale du Canada à toute succursale au Canada de La Banque Royale du Canada ou à tout autre endroit que la Société peut désigner à cette fin et qui
est approuvé par le fiduciaire. Le paiement des intérêts sur le présent Titre peut être effectué, au gré de la Société, par mandat ou par chèque posté à l’adresse
de la personne ou des personnes y ayant droit, telle que cette adresse apparaît dans le registre central des détenteurs de Titres.

 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 définis 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.

 La Société, à compter du ler juillet 1992, fera tous les efforts raisonnables pour acheter à des fins
d’annulation sur le marché libre, au cours de chaque période de trois mois, des Titres d’un montant en capital de 1 125 000 $, et ce, à des 

  

 - 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. 
 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 

  

 - 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-Jean (N.-B.),
Montréal, Toronto, Winnipeg, Regina, 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. 
 EN FOI DE QUOI, la Société a fait signer le présent Titre par ses dirigeants dûment autorisés.

 DOMTAR INC., a corporation incorporated or continued under the Canada Business Corporations Act
(hereinafter called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to the bearer, or, if this Security be registered as to principal, to
the Registered Holder hereof, on April 15, 2011 the principal sum of                      Thousand Dollars and to pay interest thereon,
semi-annually in arrears from the later of April 15, 1987 and the most recent interest payment date to which interest has been paid or duly provided for, on April 15 and October 15 in each year commencing on October 15, 1987, at
the rate of 10% per annum upon surrender of the coupons attached hereto as they severally mature. 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. 
 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, 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 Holders of the Securities and coupons,
and the 

  

 - 41 - 

 
terms upon which the Securities are, and are to be, authenticated and delivered. The Securities will 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 shall also have the right to purchase for cancellation the Securities in the market, by tender or private contract, at prices not exceeding
the price at which such Securities are redeemable, at the date of purchase, plus in each case accrued and unpaid interest to the date of purchase plus costs of purchase. The Securities purchased or redeemed by the Company shall be cancelled and
shall not be reissued. 
 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 

  

 - 42 - 

 
interest and costs of purchase. If in any three-month period, the Company is unable to purchase such principal amount of Securities for any reason, including
the fact that the Securities did not 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. 
 The Indenture permits, with certain exceptions as
therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities and the coupons under the Indenture at any time by the Company with the consent of the Holders
of two-thirds in aggregate principal amount of the Securities at the time Outstanding, as defined in the Indenture, or of such lesser amount thereof as shall have acted at a meeting of the Holders of the Securities duly held pursuant to the
provisions of the Indenture. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and of this Security and certain past defaults under the Indenture and under this Security and their consequences. Any 

  

 - 43 - 

 
such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of
any Security issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security. 
 This Security is transferable by delivery, unless registered as to principal in the name of the Holder in the Central Security Register of the Company. This Security may be so registered upon presentation hereof at the principal office of
the Trustee in the Cities of Halifax, Saint John, Montreal, Toronto, Winnipeg, Regina, Calgary and Vancouver, such registration being noted hereon. While registered as aforesaid, this Security shall be transferable on the Security Registers of the
Company by the Registered Holder hereof, upon like presentation of this Security for notation of such transfer hereon, 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 Registered Holder hereof or his attorney duly authorized in writing, all as provided in the Indenture and subject to certain limitations therein set forth; but this Security may be discharged from registration
by being in like manner transferred to bearer, and thereupon transferability by delivery shall be restored. This Security shall continue to be subject to successive registrations and transfers to bearer at the option of the bearer or Registered
Holder, as the case may be. Such registration, however, shall not affect the transferability by delivery of the coupons appertaining hereto, which shall continue to be payable to bearer and transferable by delivery. 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 registration, transfer or discharge from registration. 
  

 - 44 - 

 The Company, the Trustee and any agent of the Company or of the Trustee may treat the bearer of this
Security, or, if this Security is registered as herein authorized, the person in whose name the same is registered, and the bearer of any coupon appertaining hereto, as the owner hereof and thereof for all purposes, whether or not this Security or
such coupon be overdue. 
 The Securities are issuable as Coupon Securities, as defined in the Indenture, registrable as to principal, in the
denominations of $1,000, $5,000, $25,000 and $100,000 and as fully registered Securities without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth,
Securities are exchangeable at the principal office of the Trustee in the Cities above mentioned for a like aggregate principal amount of Securities of a different authorized kind or denomination, as requested by the Holder surrendering the same
with, in the case of any Coupon Security, all unmatured coupons and all matured coupons in default thereto appertaining, upon payment of taxes and governmental charges and other reasonable charges. 
 Unless the certificate of authentication hereon has been executed by the Trustee by the manual signature of one of its authorized officers, neither this
Security, nor any coupon appertaining hereto, shall be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose. 
 IN WITNESS WHEREOF, the Company has caused this Security to be executed by its duly authorized officers and coupons bearing the facsimile signature of its Treasurer to be hereto annexed.

	No.             	  	$             

 DOMTAR INC., société constituée ou prorogée en vertu de la Loi sur les
sociétés commerciales canadiennes (appelée dans les présentes “Société”, lequel terme comprend toute société remplaçante aux termes du contrat de fiducie mentionné
ci-après), contre valeur reçue, promet par les présentes de payer au porteur ou, si le présent Titre est immatriculé quant au capital, au détenteur inscrit dudit Titre, le 15 avril 2011 le montant en capital
de                      mille dollars et de payer les intérêts s’y rapportant semestriellement terme échu à
compter du 15 avril 1987 ou à compter de la dernière date de paiement des intérêts à laquelle des intérêts ont été versés ou mis de côté, selon celle de ces dates qui
tombera la dernière, le 15 avril et le 15 octobre, de chaque année, à compter du 15 octobre 1987, au taux annuel de 10 % sur remise des coupons attachés aux présentes au fur et à mesure qu’ils
viendront à échéance. Le paiement du capital et des intérêts sur le présent Titre sera effectué en monnaie légale du Canada à toute 

  

 - 47 - 

 
succursale au Canada de La Banque Royale du Canada, ou à tout autre endroit que la Société peut désigner à cette fin et
qui est approuvé par le fiduciaire. 
 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 et de coupons, 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.

 Tous les termes utilisés dans le présent Titre qui sont la version française de termes anglais définis dans la
version anglaise du contrat de fiducie 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 

  

 - 48 - 

 
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 intéréts 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.

 La Société, à compter du ler juillet 1992, fera tous les efforts raisonnables pour acheter à des fins
d’annulation sur le marché libre, au cours de chaque période de trois mois, des Titres d’un montant en capital de 1 125 000 $, et ce, à des 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
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. 
 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. 
 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 - 

 
liera ce 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-Jean (N.-B.), Montréal, Toronto, Winnipeg,
Regina, 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.

of, an amount sufficient to pay and discharge the entire indebtedness on the Securities and coupons (other than those referred to in (i) and (iii) of Clause (A) above) not theretofore delivered to the Trustee cancelled or for
cancellation, for principal and interest to the date of such deposit (in the case of Securities which have become due and payable), or to the Stated Maturity or Redemption Date,

to be deposited with the Trustee securities issued or guaranteed by the Government of Canada or by any province of Canada or other securities or instruments acceptable to the Trustee, the principal of and interest on which, when due, without any
reinvestment thereof, will provide moneys which will be sufficient to pay to the holders of the Securities, when due, all amounts owing in respect of the principal of and interest on the Securities, and also for the payment of all other moneys
payable hereunder by the Company.

Trustee may determine, to the Holders of the Securities and coupons for whose payment or redemption such securities or money have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such
securities or money need not be segregated from other funds except to the extent required by law.

(ii) shall have resulted in the acceleration of such indebtedness so that the same shall be or become due and payable prior to the date on which the same would otherwise have become due and payable or shall have resulted in the enforcement of
any security for such indebtedness; provided, however, that if such default under such indentures or instruments shall be remedied or cured by the Company or waived by the holders of such indebtedness, then the Event of Default hereunder by reason
thereof shall be deemed likewise to have been thereupon remedied, cured or waived without further action upon the part of either the 

  

 - 73 - 

 
Trustee or any of the Securityholders; and provided, further, that, subject to the provisions of Section 601, the Trustee shall not be charged with

seizure or attachment remains in force or such taking of possession or control continues in effect for a period of 60 days. 
 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,

 (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 

  

 - 77 - 

 
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. 
 Section 505. Trustee May Enforce Claims Without Possession of Securities or
Coupons. 
 All rights of action and claims under this Indenture or the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name on behalf of the Securityholders and as
trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities and coupons in respect of which such judgment has been recovered. 
  

 - 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 
 (1) an Event of Default shall have occurred and be continuing and such Holder
shall have previously given written notice to the Trustee of such continuing Event of Default; 
  

 - 80 - 

 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities
shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60 day period by a
Majority Securityholders’ Act; 
 it being understood and intended that no one or more Holders of Securities or coupons shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder of Securities or coupons, or to obtain or to seek to obtain priority or preference over any other such
Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders of the Securities and coupons. 
  

 - 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. Every right and remedy given by this
Article or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Securityholders, as the case may be. 
 Section 511. Control by Securityholders. 
 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 
 (1) such direction shall not be in conflict with any rule of law or this Indenture,

 (2) the Trustee shall not determine that the action so directed would be unjustly prejudicial to the Holders not taking
part in such direction, and, 
 (3) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. 
 Section 512. Waiver of Past Defaults. 
 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.

 For the purposes of the calculations required to be made under Sections 1008, 1009, 1011 and 1012: 
  

	 	(1)	 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. 
 ARTICLE ELEVEN 
 Redemption and Purchase of
Securities 
 Section 1101. Right of Redemption. 
 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 Lévesque, Beaubien 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.

Section 105(2) in the Indenture) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding. The Company further agrees to take any and all actions, including the execution and filing of any and
all such documents and instruments, as may be necessary to continue such designation and appointment of CT Corporation System in full force and effect so long as the Indenture, as supplemented by this Supplemental Indenture, shall be in full force

waives such immunity in respect of its obligations under the Indenture, as supplemented by this Supplemental Indenture, to the extent permitted by law.
