RECITALS OF THE ISSUER


WHEREAS, the Issuer and the Trustee entered into an Indenture, dated as of May 8, 2007 (the "Original Indenture").   Section 8.01(7) of the Original Indenture provides that the Issuer and the Trustee may, without the consent of any Holder, enter into a supplemental indenture to establish the form or terms of Securities of any series as permitted by Section 2.01 and 3.01 thereof.


WHEREAS, pursuant to Sections 2.01 and 3.01 of the Original Indenture, the Issuer desires to provide for the establishment of a series of Securities under the Original Indenture, and the form and terms thereof, as hereinafter set forth.


WHEREAS, the Issuer has requested that the Trustee execute and deliver this Third Supplemental Indenture.  The Issuer has delivered to the Trustee an Opinion of Counsel and an Officers' Certificate pursuant to Sections 1.02 and 8.03 of the Original Indenture to the effect, among other things, that all conditions precedent provided for in the Indenture to the Trustee's execution and delivery of this Third Supplemental Indenture have been complied with. All acts and things necessary have been done and performed to make this Third Supplemental Indenture enforceable in accordance with its terms, and the execution and delivery of this Third Supplemental Indenture has been duly authorized in all respects.


WHEREAS the proper officers of the Issuer have duly authorized the creation and issuance of a series of Securities to be designated as 7.25% Notes due 2019 (the "Notes") and to be initially limited (subject to the exceptions described herein and in the Original Indenture) to the aggregate principal amount of U.S.$350,000,000; the further terms and conditions thereof being hereinafter set forth, all in accordance with a resolution of the directors of the Issuer;


NOW, THEREFORE, THIS THIRD SUPPLEMENTAL  INDENTURE
WITNESSETH: For and in consideration of the premises and the purchase of the Securities (as herein defined) by the holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all holders of the Securities, as follows:

As used herein "Third Supplemental Indenture", "hereto", "herein", "hereof ', "hereby", "hereunder" and similar expressions refer to this Third Supplemental Indenture and



Doc#: US I :5625421v4

not to any particular Article, Section or other portion hereof and include any and every instrument supplemental or ancillary hereto or in implementation hereof, and further include the terms of the Notes set forth in the form of Notes annexed as Schedule A hereto.


		
	1.2
	Definitions in Third Supplemental Indenture




All terms contained in this Third Supplemental Indenture which are defined in the Original Indenture and not defined herein shall, for all purposes hereof, have the meanings given to such terms in the Original Indenture, unless the context otherwise specifies or requires; provided, however, that notwithstanding the foregoing, the terms "Issuer" and "Trustee" shall have the respective meanings given to them in the Original Indenture.


		
	1.3
	Interpretation not Affected by Headings




The division of this Third Supplemental Indenture into Articles and Sections, the provision of the table of contents hereto and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation of this Third Supplemental Indenture.


		
	2.
	NOTES




		
	2.1
	Form and Terms of Notes




There shall be and there is hereby created for issuance under the Original Indenture, as supplemented by this Third Supplemental Indenture; (i) a series of Securities which shall consist of an aggregate principal amount of U.S.$350,000,000 Notes; provided, however, that if the Issuer shall, at any time after the date hereof, increase the principal amount of Notes which may be issued and issue such increased principal amount (or any portion thereof), then any such additional Notes so issued shall have the same form and terms (other than the date of issuance and the date from which interest thereon shall begin to accrue and, under certain circumstances, the first interest payment date), and shall carry the same right to receive accrued and unpaid interest, as the Notes theretofore issued; and provided,  further, that, notwithstanding the foregoing, the Issuer shall not be entitled to increase the principal amount of Notes which may be issued or issue any such increased principal amount if the Issuer has effected satisfaction and discharge of the Indenture pursuant to Section 4.01 of the Original Indenture or defeasance or covenant defeasance pursuant to Article 12 of the Original Indenture.


The Notes will mature, and the principal of the Notes and accrued and unpaid interest thereon will be due and payable, on May 15, 2019, or such earlier date as the principal of any of the Notes may become due and payable in accordance with the provisions of the Original Indenture and this Third Supplemental Indenture.


The Notes shall bear interest on the principal amount thereof from May 15, 2009 or from the last date to which interest shall have been paid or duly made available for payment on the Notes, whichever is later, at the rate of 7.25% per annum, payable semi-annually in arrears on May 15 and November 15 (each, an "Interest Payment Date") in each year, commencing November 15, 2009, until the principal of and premium, if any, on the applicable series of Notes  is paid or duly made available for payment;  and should the Issuer at any time



Doc#: US I :5625421v4






3


default in the payment of any principal of, or premium, if any, or interest on the Notes when due, the Issuer shall pay interest (such interest to be payable on demand), to the extent permitted by law, on the amount in default at the same rate applicable to the Notes. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Original Indenture, be paid to the Persons in whose names the Notes (or one or more predecessor Notes) are registered at the close of business on May 1 or November 1 (the "Regular Record Dates"), as the case may be, immediately prior to such Interest Payment Date, regardless of whether any such Regular Record Date is a business day. Any such interest on the Notes not so punctually paid or duly provided for on any Interest Payment Date shall be payable, as applicable, as provided in the form of Note annexed hereto as Schedule A to this Third Supplemental Indenture.


For the purposes only of the disclosure required by the Interest Act (Canada), and without affecting the amount of interest payable to any holder of a Note or the calculation of interest on any Note, if the rate of interest on any Note is calculated on the basis of a year (the "deemed year") which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for the purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.


All payments of principal of and premium, if any, and interest on the Notes will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts, and all references herein to "United States dollars", "U.S.$" or "U.S. dollars" shall be deemed to refer to such coin or currency of the United States of America.


The principal of and premium, if any, and interest on the Notes shall be payable, and the Notes may be surrendered for exchange, registration, transfer or discharge from registration, at the Corporate Trust Office of the Trustee in the City of New York, New York, and in such other places as the Issuer may from time to time designate in accordance with the Original Indenture. The Trustee is hereby appointed as the initial Paying Agent, registrar and transfer agent for the Notes in the City of New York, New York.


The Notes shall be issued only as fully registered Notes, without coupons, in denominations of U.S.$2,000 and integral multiples of $1,000 thereafter. Each series of Notes initially will be represented by one or more global Securities (collectively, the "Global Notes") registered in the name of The Depository Trust Company, as Depositary or its nominee, or a successor depositary or its nominee.


The certificates representing the Notes shall bear the following legend:


"UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE REGISTERED FORM, THIS CERTIFICATE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY DTC TO A NOMINEE OF DTC OR BY A NOMINEE OF DTC TO DTC OR ANOTHER NOMINEE



Doc#: US I :5625421v4






4


OF DTC OR BY DTC OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE  OF SUCH SUCCESSOR   DEPOSITARY."
The Notes and the certificate of the Trustee endorsed thereon shall be in the form set out in Schedule A to this Third Supplemental Indenture with such appropriate insertions, omissions, substitutions and variations as the Trustee may approve and shall be numbered in such manner as the Trustee may approve, such approvals of the Trustee concerning any Note to be conclusively evidenced by its certification of such Note.


The Security Register referred to in Section 3.05 of the Original Indenture shall, with respect to the Notes, be kept at the office or agency in the City of New York, New York that the Issuer may from time to time designate for such purpose (which shall initially be the Corporate Trust Office of the Trustee in the City of New York, New York), and at such other place or places as the Issuer with the approval of the Trustee may hereafter designate.


The Notes shall be subject to redemption at the option of the Issuer as provided in Article 4 (Optional Redemption of Notes) of this Third Supplemental Indenture and Article 10 of the Original Indenture and repurchase by the Issuer as provided in Article 5 of this Third Supplemental Indenture. The Issuer shall not otherwise be required to redeem, purchase or repay Notes pursuant to any mandatory redemption, sinking fund or analogous provision or at the option of the holders thereof. The Notes will not be convertible into or exchangeable for securities of any Person.


The Notes shall have the other terms and provisions set forth in the forms of Notes attached hereto as Schedule A to this Third Supplemental Indenture with the same force and effect as if such terms and provisions were set forth in full herein.


2.2    Issuance of Notes


The Notes in the aggregate principal amount of U.S.$350,000,000 shall be executed by the Designated Officer of the Issuer and delivered by the Issuer to the Trustee on the date of issue for authentication and delivery pursuant to and in accordance with the provisions of Section 3.02 of the Original Indenture and, upon the requirements of such provisions being complied with, the Notes shall be authenticated by or on behalf of the Trustee and delivered by it to or upon the Issuer Order of the Issuer without any further act or formality on the part of the Issuer. The Trustee shall have no duty or responsibility with respect to the use or application of any of the Notes so certified and delivered or the proceeds thereof.


		
	3.
	OPTIONAL REDEMPTION OF NOTES




		
	3.1
	Redemption of Notes




The Notes will be redeemable at any time, in whole or from time to time in part, at the option of the Issuer (in the manner and in accordance with and subject to the terms and provisions set forth in Article 10 of the Original Indenture), at a Redemption Price equal to the greater of:

plus in each case accrued interest to the Redemption Date; provided that installments of interest on Notes which are due and payable on any date falling on or prior to a Redemption Date will be payable to the registered holders of such Notes (or one or more predecessor Notes), registered as such as of the close of business on the relevant Regular Record Dates.

Incorporated or their affiliates which are primary U.S. government securities dealers, and their respective successors; provided, however, that if any of the foregoing ceases to be a primary U.S. government securities dealer in The City of New York (a "Primary Treasury Dealer"), the Corporation will substitute therefor another Primary Treasury Dealer.
