The Company shall be entitled, upon delivery of an Officers’ Certificate and an opinion of Counsel, subject to its compliance with all of the covenants of the Indenture, to issue additional Series H Debentures pursuant to this Supplemental Trust Indenture without the consent of any holder of any class or series of Debentures. The additional Series H Debentures will have identical terms of the Series H Debentures issued on the date hereof, except that they shall be dated their date of issuance and except for such other changes as may be necessary to ensure they are treated as a single class with all other Series H Debentures. The Series H Debentures issued on the date hereof and any additional Series H Debentures issued will be treated as a single class for purposes of this Eighth Supplemental Indenture.

2.2 TERMS OF DEBENTURES

(a) The Series H Debentures shall bear interest (“Interest”) from the date hereof at the rate of 2.95% per annum calculated and payable in equal semi-annual payments of $14.75 per $1,000 principal amount in arrears (after as well as before maturity and after as well as before default with interest on overdue interest at the said rate) on April 21 and October 21 in each year (each an “Interest Payment Date”), commencing April 21, 2021 and shall mature on October 21, 2027. The record date for the payment of Interest shall be the close of business on the tenth Business Day preceding the relevant Interest Payment Date. For any interim period, interest to be paid will be computed using the Actual/365 (Canadian Bond) Day-Count Convention as adopted by the Investment Industry Association of Canada.

-5-

(b) The Company, at least two Business Days prior to an Interest Payment Date, shall deliver or cause to be delivered by prepaid mail, by courier or by an employee of the Company to the registered holders of Series H Debentures, post-dated cheques for Interest due thereon (less any tax required by law to be deducted or withheld) payable to the order of the registered holders thereof and negotiable on the Interest Payment Date. The Company may, at its option but only to the extent the Trustee has the arrangements in place to accommodate such request, cause the amount of such Interest to be paid to one or more registered holders thereof by way of electronic transfer of funds, with any such transfer to be made no later than 11:30 a.m. (Toronto time) on the date of such payment. The delivery of such cheques or electronic transfer of funds shall satisfy and discharge the liability for Interest on such Series H Debentures to the extent of the sums represented thereby (plus the amount of any tax deducted or withheld as aforesaid) unless, in the case of a cheque, such cheque shall not be paid on presentation.

(c) The Company upon maturity of the Series H Debentures shall pay, by cheque or electronic transfer of funds (to the extent the Trustee or any paying agent has the arrangements in place to accommodate such electronic transfer of funds) to the registered holders thereof, such principal amount due, together with accrued and unpaid Interest to the date of maturity, payable to the order of the registered holders thereof and negotiable on the date of the maturity of the Series H Debentures, against presentation and surrender of the Series H Debentures. The delivery of such cheques or electronic transfer of funds shall satisfy and discharge the liability for principal on such Series H Debentures to the extent of the sums represented thereby unless, in the case of a cheque, such cheque shall not be paid on presentation.

(d) The Series H Debentures will, prior to the Par Call Date, be redeemable at the option of the Company at any time, in whole or in part, upon not more than 60 days and not less than 15 days prior notice, at the higher of the Canada Yield Price and par, together in each case with accrued and unpaid interest to but excluding the date fixed for redemption. On and after the Par Call Date, the Series H Debentures will be redeemable at the option of the Company at any time, in whole or in part, upon not more than 60 days and not less than 15 days prior notice, at par, plus accrued and unpaid interest to but excluding the date fixed for redemption. Except as set out in this Eighth Supplemental Indenture, the Company will give notice of redemption and otherwise carry out the redemption of the Series H Debentures in accordance with Article 4 of the Indenture. Less than all of the Series H Debentures may be redeemed in accordance with Section 4.2 of the Indenture.

-6-

(e) Any redemption of the Series H Debentures may, at the option of the Company, be made subject to one or more conditions and, in such case, the notice of redemption shall specify, in addition to the requirements of the Indenture, the details and terms of any such event (e.g., a financing, asset disposition or other transaction) upon which such redemption is conditional. Notwithstanding the terms of the Indenture, upon the notice of any conditional redemption having been given as outlined in this Section 2.2(e), the Series H Debentures so called for redemption will become due and payable at the redemption price and on the redemption date specified in such notice of redemption only upon the fulfillment or discharge of the conditions stated in such notice of redemption to the satisfaction of the Company, acting reasonably, or the waiver of such conditions by the Company, in whole or in part, anything therein or herein to the contrary notwithstanding. For any notice of redemption that is conditional, in the event that such condition(s) are not satisfied or waived by the Company in its sole discretion on or prior to the redemption date, the redemption shall not be made and the Company shall promptly give notice (but in any event no later than the redemption date), in the manner in which the notice of redemption was given, that such condition was not satisfied or waived and such redemption shall not be made, and the Trustee shall promptly return to the holders thereof any of such Series H Debentures which had been surrendered for payment upon such redemption. For the avoidance of doubt, the Trustee shall have no responsibility for determining whether or not a condition set forth in such notice of redemption is satisfied, and shall be entitled to conclusively rely upon the Company’s determination regarding the satisfaction or waiver thereof.

2.3 FORM, TRANSFER AND ISSUANCE OF A GLOBAL DEBENTURE

(a) Form: Except as provided for in Section 2.6, the Series H Debentures shall be issued in the form of one global Debenture substantially in the form of Schedule A hereto (the “Global Debenture”) and shall bear such distinguishing letters and numbers as the Company and the Trustee may approve. The Global Debenture will be issued in the name of and deposited by the Trustee with, or on behalf of, the Depository as custodian of the Global Debenture and registered by the Trustee in the name of the Depository or its nominee. No purchaser of Series H Debentures represented by the Global Debenture will be entitled to a certificate or other instrument from the Company or the Depository evidencing that purchaser’s ownership thereof except in the circumstances contemplated in Section 2.6. Beneficial interests in the Global Debenture, constituting ownership of the Series H Debentures, will be represented only through the Book-Based System.

(b) Issuance: The Global Debenture shall be signed by any authorized signatory of the Company holding office at the time of signing and empowered to sign the Global Debenture on behalf of the Company and delivered to the Trustee. Upon receipt thereof by the Trustee, the Global Debenture shall be certified, in accordance with Section 2.7, by the Trustee and delivered to CDS pursuant to a Written Order of the Company, without the Trustee receiving consideration therefor. The Global Debenture may be delivered to the Trustee for certification, and upon certification by the Trustee, the Global Debenture may be delivered to CDS by electronic or other means.

-7-

(c) Transfer: Transfers of Series H Debentures between CDS Participants shall occur in accordance with the Depository’s rules and procedures.

2.4 DEALINGS WITH AND BY THE DEPOSITORY

All references herein to actions by, or notices given or payments made to, Debentureholders shall, where such Series H Debentures are held through the Depository, refer to actions taken by, or notices given or payments made to, the Depository upon instructions from the CDS Participants in accordance with the Depository’s rules and procedures. For the purpose of any provision of this Eighth Supplemental Trust Indenture requiring or permitting actions with the consent of or at the direction of the Debentureholders evidencing a specified percentage of the aggregate unpaid principal amount of Series H Debentures outstanding, such direction or consent may be given by Debentureholders acting through the Depository and the CDS Participants owning Series H Debentures evidencing the requisite percentage of the principal amount of Series H Debentures. The rights of a Debentureholder shall be exercised only through the Depository and the CDS Participants and shall be limited to those established by law and agreements between such Debentureholder and the Depository and/or the CDS Participants or upon instructions from the CDS Participants. Each of the Company and the Trustee may deal with the Depository for all purposes (including the making of payments) as the authorized representative of the respective Debentureholders and such dealings with the Depository shall constitute satisfaction or performance, as applicable, of its respective obligations hereunder.

In the event of a vote by registered Debentureholders pursuant to the Indenture when the Series H Debentures are held through the Depository, the Depository shall vote such Series H Debentures upon instructions from the CDS Participants in accordance with the Depository’s rules and procedures, and if such vote requires the approval of a specified percentage of the aggregate unpaid principal amount of Series H Debentures outstanding, the approval of CDS Participants owning Series H Debentures evidencing the requisite percentage of the principal amount of Series H Debentures shall be sufficient.

2.5 NOTICES TO THE DEPOSITORY

For so long as the Series H Debentures are held through the Depository, if any notice or other communication is required to be given to Debentureholders, the Trustee and the Company shall give all such notices and communications through the Depository, which shall be in accordance with applicable law and regulation.

2.6 FORM AND ISSUANCE OF DEFINITIVE DEBENTURE CERTIFICATES

(a) Form: If: (i) the Depository resigns or is removed from its responsibilities as depository and the Company is unable or does not wish to locate a qualified successor or if the Book-Based System for the Series H Debentures otherwise ceases to exist; (ii) the Company determines that it wishes definitive Debentures to replace the Global Debenture and notifies the Depository to such effect; (iii) required by applicable law; or (iv) after an Event of Default has occurred, the holders of Series H Debentures representing beneficial interests aggregating over 50% of the outstanding principal amount of Series H Debentures determine that the continuation of ownership through the Book-Based System is no longer in their best interests, the Depository shall surrender the Global Debenture to the Trustee with instructions from the Depository for re-registration of each Debenture in the name and as to the principal amount specified by the Depository, and the Company shall issue and the Trustee shall certify and deliver the aggregate unpaid principal amount of the Series H Debentures then outstanding in the form of definitive Series H Debenture certificates (the “Definitive Debentures”) representing such Debentures.

-8-

(b) The Definitive Debentures shall be issued as fully-registered Debentures in denominations of $1,000 and integral multiples thereof. Each Definitive Debenture and the certificate of the Trustee in respect thereof endorsed thereon shall be substantially in the form set forth in Schedule A annexed hereto in respect of the Global Debenture with such changes, additions and deletions as are necessary. The Definitive Debentures may be typed, engraved, printed or lithographed, or partly in one form and partly in another, as the Company may determine. The Definitive Debentures shall be signed (either manually or by facsimile or other electronic signature) by any authorized signatory of the Company holding office at the time of signing and empowered to sign such Definitive Debentures on behalf of the Company. A facsimile or other electronic signature upon any of the Definitive Debentures shall for all purposes of this Eighth Supplemental Trust Indenture be deemed to be the signature of the person whose signature it purports to be and to have been signed at the time such facsimile or other electronic signature is reproduced and, notwithstanding that any person whose signature, either manual or in facsimile or other electronic means, appears on the Definitive Debentures is not at the date of this Eighth Supplemental Trust Indenture or at the date of the Definitive Debentures or at the date of the certification and delivery thereof an officer of the Company, such Definitive Debentures shall be valid and binding upon the Company and entitled to the benefits of this Eighth Supplemental Trust Indenture.

(c) Issuance: The Definitive Debentures shall forthwith upon their issue, having been authorized and executed by the Company, be delivered to the Trustee. Upon receipt thereof by the Trustee, the Definitive Debentures shall be certified by the Trustee and delivered to or to the order of the Company pursuant to a Written Order of the Company, without the Trustee receiving consideration therefor.

(d) Transfer: Transfers of Definitive Debentures shall be governed by the provisions of Article 3 of the Indenture.

2.7 CERTIFICATION

No Series H Debenture shall be issued or, if issued, shall be obligatory or shall entitle the Debentureholder to the benefits of this Eighth Supplemental Trust Indenture until it has been certified by or on behalf of the Trustee. Such certificate on any Series H Debenture shall be conclusive evidence as against the Company that such Series H Debenture is duly issued and is a valid obligation of the Company and that the holder is entitled to the benefits hereof.

-9-

The certificate of the Trustee signed on the Series H Debentures shall not be construed as a representation or warranty by the Trustee as to the validity of this Eighth Supplemental Trust Indenture or of the Series H Debentures or their issuance and the Trustee shall in no respect be liable or answerable for the use made of said Series H Debentures or either of them or the proceeds thereof. The certificate of the Trustee signed on the said Series H Debentures shall, however, be a representation and warranty by the Trustee that said Series H Debentures have been duly certified by or on behalf of the Trustee pursuant to the provisions of this Eighth Supplemental Trust Indenture.

2.8 RANKING

The Series H Debentures are direct unsecured obligations of the Company and rank equally and rateably with one another and with all other present and future unsecured and unsubordinated indebtedness of the Company, except to the extent prescribed by law.
