In any case where notice to Holders of the Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of the Securities given as provided. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

In case, by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impractical to mail notice of any event to Holders of the Securities when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be sufficient giving of such notice for every purpose hereunder.

Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

Where this Indenture provides for notice 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 Holders 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.

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

All covenants and agreements in this Indenture by the Corporation and the Trustee shall bind their successors and assigns, whether so expressed or not.

In case any provision in this Indenture or in any Security shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Authenticating Agent, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York without regard to principles of conflicts of law. This Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions.

In any case where any Interest Payment Date, Redemption Date, Special Mandatory Redemption Date or Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of any Security, other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section), payment of principal (or premium, if any) or interest, if any, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, Special Mandatory Redemption Date or at the Stated Maturity or Maturity; provided that no additional interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Special Mandatory Redemption Date, Stated Maturity or Maturity, as the case may be.

SECTION 113. Agent for Service; Submission to Jurisdiction; Waiver of Immunities; Waiver of Jury Trial.

By the execution and delivery of this Indenture, the Corporation (i) acknowledges that it has irrevocably designated and appointed CT Corporation System, 111 8^th Avenue, 13^th Floor, New York, New York, 10011 (“CT Corporation”) as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the Securities or this Indenture that may be instituted in any federal or New York state court located in New York, New York or brought under federal or state securities laws or brought by the Trustee (whether in its individual capacity or in its capacity as Trustee hereunder), (ii) submits to the non-exclusive

jurisdiction of any such court in any such suit or proceeding, and (iii) agrees that service of process upon CT Corporation and written notice of said service to the Corporation (mailed or delivered to the Corporation, Attention: General Counsel, at its principal office specified in the first paragraph of this Indenture and in the manner specified in Section 105 hereof), shall be deemed in every respect effective service of process upon the Corporation in any such suit or proceeding. The Corporation further agrees to take any and all action, 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 in full force and effect so long as any of the Securities shall be outstanding.

To the extent that the Corporation has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, the Corporation hereby irrevocably waives such immunity in respect of its obligations under this Indenture and the Securities, to the extent permitted by law.

The Corporation hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Indenture or the Securities in any federal or state court in the State of New York, Borough of Manhattan. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(a) The Corporation covenants and agrees that the following provisions shall apply to conversion of currency in the case of the Securities and this Indenture:

(1) If for the purposes of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into any other currency (the “Judgment Currency”) an amount due or contingently due under the Securities of any series and this Indenture (the “Required Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day in such country before the day on which a final judgment which is not appealable or is not appealed is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

(2) If there is a change in the rate of exchange prevailing between the Business Day in such country before the day on which the judgment referred to in (1) above is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Corporation shall pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the Judgment Currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Required Currency originally due.

(b) In the event of the winding-up of the Corporation at any time while any amount or damages owing under the Securities and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Corporation shall indemnify and hold the Holders of Securities and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the equivalent of the amount in the Required Currency (other than under this Subsection (b)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this Subsection (b) the final date for the filing of proofs of claim in the winding-up of the Corporation shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Corporation may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

(c) The obligations contained in Subsections (a)(2) and (b) of this Section shall constitute separate and independent obligations of the Corporation from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Corporation, shall apply irrespective of any waiver or extension granted by any Holder or Trustee from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Corporation for a liquidated sum in respect of amounts due hereunder (other than under Subsection (b) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Corporation or the applicable liquidator. In the case of Subsection (b) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

(d) The term “rate(s) of exchange” shall mean the Bank of Canada daily average exchange rate for purchases on the relevant date of the Required Currency with the Judgment Currency, as reported on the “Exchange Rates—Daily exchange rates” page of the website of Bank of Canada (or by such other means of reporting the Bank of Canada daily average exchange rate as may be agreed upon by each of the parties to this Indenture) and includes any premiums and costs of exchange payable.

Except as otherwise provided in this Indenture, for purposes of the construction of the terms of this Indenture or of the Securities, in the event that any amount is stated herein in the Currency of one nation (the “First Currency”), as of any date such amount shall also be deemed to represent the amount in the Currency of any other relevant nation (the “Other Currency”) which is required to purchase such amount in the First Currency at the Bank of Canada daily

average exchange rate as reported on the “Exchange Rates—Daily exchange rates” page of the website of Bank of Canada (or by such other means of reporting the Bank of Canada daily average exchange rate as may be agreed upon by each of the parties to this Indenture) on the date of determination.

UNLESS PERMITTED UNDER CANADIAN SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY IN OR TO A PERSON IN ANY PROVINCE OR TERRITORY OF CANADA BEFORE SUCH DATE THAT IS FOUR MONTHS AND A DAY AFTER THE ISSUANCE OF THE SECURITY

Cenovus Energy Inc., a corporation duly organized and existing under the laws of Canada (herein called the “Corporation”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of US$[ ] ([ ] DOLLARS) on [ ], at the office or agency of the Corporation referred to below, and to pay interest thereon on [ ] and semi-annually thereafter, on [ ] and [ ] in each year, from [ ], or from the most recent Interest Payment Date to which interest has been paid or duly provided for, at the rate of [ ]% per annum until the principal hereof is paid or duly provided for, and (to the extent lawful) to pay on demand interest on any overdue interest at the rate borne by the Securities from the date on which such overdue interest becomes payable to the date payment of such interest has been made or duly provided for. 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) is registered at the close of business on the Regular Record Date for such interest, which shall be [ ] or [ ] (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest which is payable but is not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Holder on the relevant Regular Record Date, and such defaulted interest, and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities, may 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 than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth herein.

Unless the certificate of authentication hereon has been duly executed by the Trustee by manual signature, this Security shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly executed.

This Security is one of a duly authorized issue of securities of the Corporation designated as its [ ]% Notes due [ ] (herein called the “Securities”), issued pursuant to an indenture (herein called the “Indenture”) dated as of April 7, 2017 among the Corporation and The Bank of New York Mellon, as 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, limitations of rights, duties, obligations and immunities thereunder of the Corporation, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is a Global Security representing US$[ ] aggregate principal amount of the Securities of this series.

The Corporation may from time to time without notice to, or the consent of, the Holders, create and issue Additional Securities under the Indenture.

Payment of the principal of (and premium, if any, on) and interest, if any, on this Security will be made at the office or agency of the Corporation maintained or caused to be maintained for that purpose, 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; provided, that principal paid in relation to any Security, redeemed at the option of the Corporation or upon Maturity, shall be paid to the holder of such Security only upon presentation and surrender of such Security to such office or agency referred to above. Payments in respect of any Security represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by DTC.

The Corporation will pay to the Holders such Additional Amounts as may be payable under Section 1005 of the Indenture.

The Securities are subject to redemption prior to [ ], in whole or in part, at the option of the Corporation, upon not less than 10 nor more than 60 days’ notice, at any time and from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Securities to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed that would be due if the Securities matured on [ ] (exclusive of the payments of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) plus [ ] basis points, plus, in the case of (1) and (2), accrued interest thereon to the date of redemption.

On or after [ ], the Securities may be redeemed, in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon to the date of Redemption.

In the case of a partial redemption of Securities, selection of such Securities for redemption will be made in accordance with DTC procedures. If any Security is redeemed in part, the notice of redemption relating to such Security shall state the portion of the principal amount thereof to be redeemed; provided that no Security in an aggregate principal amount of US$2,000 or less shall be redeemed in part. A replacement Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holders thereof upon cancellation of the original Security.

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

The Securities are subject to redemption as a whole but not in part, at the option of the Corporation, as provided in Section 1110 of the Indenture.

If, on or before the Transaction Closing Deadline, (1) the Acquisition is not consummated on substantially the terms described in the Final Offering Memorandum or (2) the Corporation notifies the Trustee in writing or publicly announces that it will not proceed with the Acquisition for any reason, the Corporation will cause to be redeemed all of the Securities then outstanding, in whole and not in part, on or prior to the Special Mandatory Redemption Date. In the event of a Special Mandatory Redemption, the Special Mandatory Redemption Price will be equal to 101% of the aggregate principal amount of the Securities plus accrued interest to, but not including, the Special Mandatory Redemption Date.

In the case of any redemption of Securities, interest instalments whose Stated Maturity is on or prior to the Redemption Date, or the Special Mandatory Redemption Date, as the case may be, will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Date referred to on the face hereof. Securities (or portions thereof) for whose redemption provision is made in accordance with the Indenture shall cease to bear interest from and after the Redemption Date, or the Special Mandatory Redemption Date, as the case may be.

In the event of redemption of this Security in part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

If an Event of Default shall occur and be continuing, the principal of all the Securities, and all accrued and unpaid interest thereon, may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Corporation on this Security and (b) certain restrictive covenants and the related Defaults and Events of Default, upon compliance by the Corporation with certain conditions set forth therein, which provisions apply to this Security.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Corporation and the rights of the Holders under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of all affected Securities at the time Outstanding. 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 affected thereby, to waive compliance by the Corporation with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by or on behalf of 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 upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest, if any, on this Security at the times, place, and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable on the Security Register of the Corporation, upon surrender of this Security for registration of transfer at the office or agency of the Corporation maintained or caused to be maintained for such purpose duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Corporation and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities are issuable only in registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same.

Except as otherwise provided in the Indenture, prior to the time of due presentment of this Security for registration of transfer, the Corporation, the Trustee and any agent of the Corporation or 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, and none of the Corporation, the Trustee or any agent shall be affected by notice to the contrary.

Interest on this Security shall be computed on the basis of a 360-day year of twelve 30-day months. Solely for the purposes of disclosure under the Interest Act (Canada) and without affecting the calculation of the amount of interest owing on this Security, the yearly rate of interest to which interest calculated under a Security for a period of less than one year on the basis of a year of 360 days consisting of twelve 30 day months (the “calculation period”) is equivalent will be such rate of interest multiplied by a fraction of which (i) the numerator is the product of (A) the actual number of days in the year commencing on the first day of such calculation period, multiplied by (B) the sum of (y) the product of 30 multiplied by the number of complete months elapsed in such calculation period and (z) the actual number of days elapsed in any incomplete month in such calculation period; and (ii) the denominator is the product of (A) 360 multiplied by (B) the actual number of days in such calculation period.

If at any time, (i) the Depositary notifies the Corporation that it is unwilling or unable or no longer qualifies to continue as Depositary for these Securities or if at any time the Depositary shall no longer be registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation and a successor depositary is not appointed by the Corporation within 90 days after the Corporation receives such notice or becomes aware of such condition, as the case may be, (ii) the Corporation determines that the Securities shall no longer be represented by a Global Security or Securities, or (iii) there shall have occurred and be continuing an Event of Default under the Indenture with respect to the Securities and the Trustee has received a written request from the Depositary or a participant in the Depositary in accordance with the Depositary’s customary procedures to issue Securities in definitive form to such participant or other beneficial owner specified by such participant to the Trustee in writing, then in such event the Corporation will execute and the Trustee will authenticate and deliver Securities in definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of this Security in exchange for this Security. Such Securities in definitive registered form shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Subject to Section 612, the Trustee’s certificate of authentication shall be in substantially the following form:

The Stated Maturity of the 5.40% Senior Notes due 2047 shall be June 15, 2047 and they shall bear interest at the rate of 5.40% per annum, from April 7, 2017, or the most recent Interest Payment Date to which interest has been paid or duly provided for, payable on December 15, 2017 and semi-annually thereafter on June 15 and December 15 in each year and at said Stated Maturity, until the principal thereof is paid or duly provided for.

Payment of the principal of (and premium, if any, on) and interest, if any, on these Securities will be made at the office or agency of the Corporation maintained or caused to be maintained for that purpose, 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, provided that principal paid in relation to any Security, redeemed at the option of the Corporation or upon Maturity, shall be paid to the holder of such Security only upon presentation and surrender of such Security to such office or agency referred to above.

Additional Securities of any series ranking equal to the Original Securities of such series in all respects or, in all respects except for the payment of interest accruing prior to the issue date of the Additional Securities of that series or except for the initial interest payment

following the issue date of the Additional Securities of that series, may be created and issued from time to time by the Corporation without notice to or consent of the Holders and may be consolidated with and form a single series with the Securities of that series initially issued and shall have the same terms as to status, redemption or otherwise as the Securities of that series originally issued.

The Securities of each series, other than Securities issued in global form (which may be of any denomination), shall be issuable in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

The Securities shall be executed on behalf of the Corporation by its Chairman, its President, its Chief Executive Officer, its Chief Financial Officer or a Vice-President, together with any one of the Corporate Secretary, or Assistant Corporate Secretary, the Treasurer or an Assistant Treasurer. The signature of any of these officers on the Securities may be the manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Corporation shall bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Exchange Securities to be issued in exchange for the Initial Securities (the “Initial Exchange Securities”) or may deliver Additional Securities of any series, in each case, executed by the Corporation to the Trustee for authentication, together with a Corporation Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Corporation Order shall authenticate and deliver such Securities.

In authenticating such Initial Exchange Securities or Additional Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, one or more Opinions of Counsel stating that such Securities, when completed by appropriate insertions and executed and delivered by the Corporation to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Corporation in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legal, valid and binding obligations of the Corporation, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equitable principles.

The Trustee shall not be required to authenticate and deliver any such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

No Security 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 form provided for herein duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Corporation, and the Corporation shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Corporation, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never entitle a Holder to the benefits of this Indenture.

Pending the preparation of definitive Securities, the Corporation may execute and, upon receipt of the documents required by Section 303, together with a Corporation Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities are issued, the Corporation shall 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 the office or agency of the Corporation to be maintained as provided in Section 1002, without charge to the Holder; and upon surrender for cancellation of any one or more temporary Securities the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations and of like tenor and terms. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Securities represented thereby pursuant to this Section 304 or Section 305, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such temporary Global Security shall be reduced for all purposes by the amount so exchanged and endorsed.

The Corporation shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Securities (the registers maintained in the Corporate Trust Office of the Trustee and in any other office or agency of the Corporation in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Corporation shall provide for the registration of Securities and of transfers of Securities. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Security Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as security registrar (the “Security Registrar”) for the purpose of registering Securities and transfers of Securities as herein provided. The Corporation shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Corporation and shall have accepted such appointment by the Corporation. In the event that the Trustee shall not be or shall cease to be the Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for such series of Securities.

Upon surrender for registration of transfer of any Security of any series at the office or agency in a Place of Payment for that series, the Corporation shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee, one or more new Securities of the same series, of any authorized denominations and of a like principal amount and tenor and evidencing the same indebtedness.

At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denomination and of a like principal amount and tenor and evidencing the same indebtedness, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

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

Notwithstanding the foregoing, any permanent Global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent Global Security is entitled to exchange such interest for Securities of such series and of like principal amount and tenor and evidencing the same indebtedness of another authorized form and denomination, provided that any applicable notice provided in the permanent Global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Corporation shall deliver to the Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent Global Security, executed by the Corporation. On or after the earliest date on which such interests may be so exchanged, such permanent Global Security shall be surrendered by the Depositary as shall be specified in the Corporation Order

with respect thereto to the Trustee, as the Corporation’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent Global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent Global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption. If a Security is issued in exchange for any portion of a permanent Global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent Global Security is payable in accordance with the provisions of this Indenture.

If at any time the Depositary for Securities of a series notifies the Corporation that it is unwilling, unable or no longer qualifies to continue as Depositary for Securities of such series or if at any time the Depositary for Securities for such series shall no longer be registered or in good standing under the Exchange Act, or other applicable statute or regulation, the Corporation shall appoint a successor Depositary with respect to Securities for such series. If a successor to the Depositary for Securities is not appointed by the Corporation within 90 days after the Corporation receives such notice or becomes aware of such condition, as the case may be, and the Trustee, as Security Registrar, has received a written request from the Depositary or a participant in the Depositary in accordance with the Depositary’s customary procedures to issue Securities in definitive form to such participant or other beneficial owner specified by such participant to the Trustee in writing, the Depositary shall no longer continue as Depositary with respect to Securities for such series and the Corporation will execute, and the Trustee, upon receipt of a Corporation Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver individual Securities of such series in certificated, fully registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of a Global Security or Securities representing such series in exchange for such Global Security or Securities.

The Corporation may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more global Securities shall no longer be represented by such Global Security or Securities. In such event the Corporation will execute, and the Trustee, upon receipt of a Corporation Order for the authentication and delivery of definitive Securities of such series, will authenticate and deliver Securities of such series in definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of a Global Security or Securities representing such series in exchange for such Global Security or Securities.

Upon the exchange of a Global Security for Securities in definitive registered form, such Global Security shall be cancelled by the Trustee. Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such Securities to the persons in whose names such Securities are so registered.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Corporation, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

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

No service charge shall be made for any registration of transfer or exchange of Securities, but the Corporation and the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1109 not involving any transfer.

The Corporation shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of that series under Section 1102 or 1103 and ending at the close of business on the day of the mailing 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, except the unredeemed portion of any Security being redeemed in part.

None of the Corporation, the Trustee, any agent of the Corporation, or the Trustee, any Paying Agent, the Registrar or any transfer agent shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities and this Indenture shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of beneficial owners in the Global Security shall be exercised only through the Depositary subject to the applicable procedures. The Trustee, any agent of the Trustee, any Paying Agent, the Registrar and any transfer agent shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. The Trustee, any agent of the Trustee, any Paying Agent, the Registrar and any transfer agent shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered Holder of any Global Security for all purposes of this Indenture relating to such Global Security (including the payment of principal, premium, if any, and interest and Additional Amounts, if any, and the giving of instructions or directions by or to the owner or Holder of a beneficial ownership interest in such Global Security) as the sole Holder of such Global Security and shall have no obligations to the beneficial owners thereof. None of the Corporation, the Trustee, any

agent of the Trustee, any Paying Agent, the Registrar or any transfer agent shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of any such Depositary, including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between the Depositary and any members of, or participants in, the Depositary (each, an “Agent Member”) or between or among the Depositary, any such Agent Member and/or any holder or owner of a beneficial interest in such Global Security, or for any transfers of beneficial interests in any such Global Security.

If any mutilated Security is surrendered to the Trustee, the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like principal amount and tenor and evidencing the same indebtedness and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Corporation and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Corporation or the Trustee that such Security has been acquired by a protected purchaser (as defined in Article 8 of the UCC), the Corporation shall execute and upon Corporation Order the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like principal amount and tenor and evidencing the same indebtedness and bearing a number not contemporaneously outstanding.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Corporation in its discretion may, instead of issuing a new Security, pay such Security.

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

Every new Security of any series issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original contractual obligation of the Corporation, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and the Holders of such Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, 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.

Interest, if any, on any 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 such Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Corporation maintained for such purpose pursuant to Section 1002, provided, that principal paid in relation to any Security redeemed at the option of the Corporation pursuant to Article Eleven, except pursuant to Section 1103, or paid at Maturity, shall be paid to the Holder of such Security only upon presentation and surrender of such Security to such office or agency referred to in this Section 307. Payments in respect of any Security represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Depositary.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the relevant Regular Record Date, and such defaulted interest and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities of such series (such defaulted interest and, if applicable, interest thereon herein collectively called “Defaulted Interest”) may be paid by the Corporation, at its election in each case, as provided below:

The Corporation may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (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 Corporation shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Corporation 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 on or 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 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 Corporation of such Special Record Date and, in the name and at the expense of the Corporation, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided in Section 106, not less than 10 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 name the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date.

Subject to the foregoing provisions of this Section and Section 305, 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.

Prior to due presentment of a Security for registration of transfer, the Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest, if any, on such Security and for all other purposes whatsoever (except for determining whether the payment of Additional Amounts is required), whether or not such Security be overdue, and none of the Corporation, the Trustee or any agent of the Corporation or the Trustee shall be affected by notice to the contrary.

The Depositary for Securities may be treated by the Corporation, the Trustee, and any agent of the Corporation or the Trustee as the owner of such Global Security for all purposes whatsoever (except for determining whether the payment of Additional Amounts is required). None of the Corporation, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Notwithstanding anything to the contrary in this Indenture, the Depositary or its nominee, as a Holder of a Global Security, may grant proxies and otherwise authorize any Person (including owners of beneficial interests in the Securities) to take any action that the Depositary or its nominee, as a Holder of a Global Security, is entitled to take under this Indenture or the Securities, provided further that, with respect to any Global Security, nothing herein shall prevent the Corporation, the Trustee, or any agent of the Corporation or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary, as a Holder, with respect to such Global Security or impair, as between such Depositary and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security.

All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall be promptly cancelled by it. The Corporation may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Corporation has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. If the Corporation shall so acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until

the same are surrendered to the Trustee for cancellation. 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 held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures and, upon written request of the Corporation, certification of their disposal delivered to the Corporation unless by Corporation Order the Corporation shall direct that cancelled Securities be returned to it.

Interest, if any, on the Securities shall be computed on the basis of a 360 day year of twelve 30 day months. Solely for the purposes of disclosure under the Interest Act (Canada) and without affecting the calculation of the amount of interest owing on the Securities, the yearly rate of interest to which interest calculated under a Security for a period of less than one year on the basis of a year of 360 days consisting of twelve 30-day months (the “calculation period”) is equivalent will be such rate of interest multiplied by a fraction of which (i) the numerator is the product of (A) the actual number of days in the year commencing on the first day of such calculation period, multiplied by (B) the sum of (y) the product of 30 multiplied by the number of complete months elapsed in such calculation period and (z) the actual number of days elapsed in any incomplete month in such calculation period; and (ii) the denominator is the product of (A) 360 multiplied by (B) the actual number of days in such calculation period. The interest period relating to an Interest Payment Date shall be the period from but not including the preceding Interest Payment Date to and including the relevant Interest Payment Date.

Payment of the principal of (and premium, if any) and interest, if any, on any Security shall 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.

This Indenture shall upon a Corporation Request cease to be of further effect with respect to any series of Securities specified in such Corporation Request (except as to any surviving rights of registration of transfer or exchange of Securities of such series expressly provided for herein or pursuant hereto and any right to receive Additional Amounts as contemplated by Section 1005) and the Trustee, at the expense of the Corporation, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series when

(A) all Securities of such series theretofore authenticated and delivered (other than Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and Securities of such series for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Corporation and thereafter repaid to the Corporation, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

(iii) if redeemable at the option of the Corporation, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Corporation,

and the Corporation, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest, if any, 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, as the case may be;

(2) the Corporation has paid or caused to be paid all other sums payable hereunder by the Corporation in respect of such series; and

(3) the Corporation has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Corporation to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 612 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Corporation acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

“Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) default in the payment of any interest on any Security of that series, when such interest becomes due and payable, and continuance of such default for a period of 30 days; or

(2) default in the payment of the principal of (or premium, if any, on) any Security of that series when it becomes due and payable; or

(3) default in the performance, or breach, of any covenant or warranty of the Corporation in this Indenture in respect of Securities of that series (other than a covenant or warranty a default in the performance of which, or the breach of which, is specifically dealt with elsewhere in this Indenture), and continuance of such default or breach for a period of 60 days after the receipt by the Corporation of written notice specifying such default or breach, and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder (i) to the Corporation (attention of the General Counsel to the Corporation via facsimile, with a hard copy then sent, by registered or certified mail) by the Trustee or (ii) to the Corporation (in the same manner) and the Trustee by the Holders of at least 25% in principal amount of all Outstanding Securities of any series affected thereby; or

(4) if an event of default (as defined in any indenture or instrument under which the Corporation or any of its Restricted Subsidiaries has at the time of this Indenture or shall thereafter have outstanding any indebtedness for borrowed money) shall happen and be continuing, or the Corporation or any of its Restricted Subsidiaries shall have failed to pay principal amounts with respect to such indebtedness at maturity and such event of default or failure to pay shall result in such indebtedness being declared due and payable or otherwise being accelerated, in either event so that an amount in excess of the greater of $150,000,000 (or its equivalent in any other currency) and 3.5% of the Shareholders’ Equity of the Corporation shall be or become due and payable upon such declaration or otherwise accelerated prior to the date on which the same would otherwise have become due and payable (the “Accelerated Indebtedness”), and such acceleration shall not be rescinded or annulled, or such event of default or failure to pay under such indenture or instrument shall not be remedied or cured, whether by payment or otherwise, or waived by the holders of such Accelerated Indebtedness, then (a) if the Accelerated Indebtedness shall be as a result of an event of default which is not related to the failure to pay principal or interest on the terms, at the times and on the conditions set out in any such indenture or instrument, it shall not be considered an Event of Default for purposes of this

Indenture until 30 days after such indebtedness has been accelerated, or (b) if the Accelerated Indebtedness shall occur as a result of such failure to pay principal or interest or as a result of an event of default which is related to the failure to pay principal or interest on the terms, at the times, and on the conditions set out in any such indenture or instrument, then (i) if such Accelerated Indebtedness is, by its terms, Non-Recourse Debt to the Corporation or its Restricted Subsidiaries, it shall not be considered an Event of Default for purposes of this Indenture; or (ii) if such Accelerated Indebtedness is recourse to the Corporation or its Restricted Subsidiaries, any requirement in connection with such failure to pay or event of default for the giving of notice or the lapse of time or the happening of any further condition, event or act under such other indenture or instrument in connection with such failure to pay principal or an event of default shall be applicable together with an additional seven days before being considered an Event of Default for purposes of this Indenture; or

(5) the entry of a decree or order by a court having jurisdiction in the premises adjudging the Corporation a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Corporation under the Bankruptcy and Insolvency Act (Canada), the Companies’ Creditors Arrangement Act (Canada) or any other applicable insolvency law, or appointing a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Corporation or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 90 consecutive days; or

(6) the institution by the Corporation of proceedings to be adjudicated a bankrupt or insolvent, or the consent by it to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under the Bankruptcy and Insolvency Act (Canada), the Companies’ Creditors Arrangement Act (Canada) or any other applicable insolvency law, or the consent by it to the filing of any such petition or to the appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Corporation or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due.

If an Event of Default described in Section 501 with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such affected series may, subject to any subordination provisions thereof, declare the principal amount of all of the Securities of that series, and all accrued and unpaid interest thereon to the date of such acceleration, to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series (or of all series, as the case may be) has been made, but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in principal amount of the Outstanding Securities of that series (or of all series, as the case may be), by written notice to the Corporation and the Trustee, may rescind and annul such declaration and its consequences if:

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

(A) all overdue interest, if any, on all Outstanding Securities of that series (or of all series, as the case may be),

(B) all unpaid principal of (and premium, if any, on) any Outstanding Securities of that series (or of all series, as the case may be), which has become due otherwise than by such declaration of acceleration, and interest on such unpaid principal at the rate or rates prescribed therefor in such Securities,

(C) to the extent that payment of such interest is lawful, interest on overdue interest, if any, at the rate or rates prescribed therefor in such 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 with respect to Securities of that series (or of all series, as the case may be), other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

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

Notwithstanding the preceding paragraph, in the event of a declaration of acceleration in respect of the Securities because of an Event of Default specified in Section 501(4) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the indebtedness that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Corporation and countersigned by the holders of such indebtedness or a trustee, fiduciary or agent for such holders, within 30 days after such declaration of acceleration in respect of the Securities, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period.

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

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

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

then the Corporation will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, if any, and interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amounts 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 Corporation fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Corporation or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Corporation or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series (or of all series, as the case may be) occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series (or of all series, as the case may be) by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Corporation or any other obligor upon the Securities or the property of the Corporation or the property 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 Corporation for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1) to file and prove a claim for the whole amount of principal (and premium, if any), and interest, if any, owing and unpaid in respect of the Securities 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 allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name 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 in respect of which such judgment has been recovered.

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 premium, if any) or interest, if any, upon presentation of the Securities, or both, as the case may be, and the notation thereon of the payment if only partially paid or upon surrender thereof if fully paid:

Second: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest, if any, on the Securities 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 for principal (and premium, if any) and interest, if any, respectively; and

Third: The balance, if any, to the Corporation or to such Person or Persons as the Corporation instructs in writing.

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

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

(2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of that series in the case of any Event of Default described in Section 501, 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 the Holders of a majority or more in principal amount of the Outstanding Securities of that series in the case of any Event of Default described in Section 501;

it being understood and intended that no one or more of such Holders 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 Holders of Securities of the same series, in the case of any Event of Default described in Section 501, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of Securities of the same series, in the case of any Event of Default described in Section 501.

SECTION 508. Unconditional Right of Holders to Receive Principal (Premium, if any) and Interest.

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Twelve) and in such Security, of the principal of (and premium, if any) and (subject to Section 307) interest, if any, on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

If the Trustee or any Holder 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, subject to any determination in such proceeding, the Corporation, the Trustee and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities 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 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.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default 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 Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Subject to Article Six, with respect to the Securities of any series, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series 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, relating to or arising under Section 501, provided that in each case

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders of Securities of such series not consenting.

Subject to Section 502, the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past or existing default described in Section 501, and its consequences, except a default

(1) in respect of the payment of the principal of (or premium, if any) or interest, if any, on any Security, or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, any such default shall cease to exist, and any Event of Default arising therefrom 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 Event of Default or impair any right consequent thereon.

The Corporation covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Corporation (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

All parties to this Indenture agree, and each Holder, by acceptance of a Security, shall be deemed to have agreed that, in any suit for the enforcement of any right or remedy under this Indenture, or any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, any court may, in its discretion, require 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; provided, however, that the provisions of this Section 515 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate Securities representing more than 10% of the aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of any installment of interest on any Security on or after the Stated Maturity thereof expressed in such Security or for the enforcement of the payment of the principal of such Security at the Stated Maturity therefore.

Within 90 days after the occurrence of any Default hereunder with respect to the Securities, the Trustee shall transmit in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, notice of such Default hereunder known to the Trustee, unless such

Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of (or premium, if any) or interest, if any, on any Security of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series, and so advises the Corporation in writing; and provided further, that in the case of any Default of the character specified in Section 501(3) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof.

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default that may have occurred, shall undertake to perform with respect to Securities of any series, such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants shall be read into this Indenture against the Trustee. If an Event of Default has occurred and is continuing and a Responsible Officer has actual knowledge thereof, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(1) prior to the occurrence of an Event of Default and after the curing or waiving of all such Events of Default that may have occurred:

(i) the duties and obligations of the Trustee with respect to Securities of any series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture and the Trust Indenture Act;

but in the case of any such certificates or opinions that by any provision hereof or Section 314 of the Trust Indenture Act are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by them in good faith in accordance with the direction of the Holders of not less than a majority in principal amount of Securities of any series at the time Outstanding relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture; and

(4) notwithstanding anything contained herein to the contrary, subject to the provisions of Sections 315(a) through 315(d) of the Trust Indenture Act, the Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(c) Whether or not therein expressly so provided, except to the extent expressly provided herein to the contrary, every provision of this Indenture relating to the conduct or effecting the liability or affording protection to the Trustee, shall be subject to the provisions of this Section.

Subject to the provisions of Sections 315(a) through 315(d) of the Trust Indenture Act:

(1) the Trustee may, in good faith, rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(2) any request or direction of the Corporation mentioned herein shall be sufficiently evidenced by a Corporation Request or Corporation Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution;

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s Certificate;

(4) before the Trustee acts or refrains from acting, the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders of Securities of any series pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Corporation, personally or by agent or attorney;

(7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(8) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(9) except as otherwise specifically provided herein, (i) all references in this Indenture to the Trustee shall be deemed to refer to the Trustee in its capacity as Trustee and in its capacities as Security Registrar, Authenticating Agent and Paying Agent and (ii) every provision of this Indenture relating to the conduct or affecting the liability or offering protection, immunity or indemnity to the Trustee shall be deemed to apply with the same force and effect to the Trustee acting in its capacities as Paying Agent, Authenticating Agent and Security Registrar;

(10) in no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action;

(11) the Trustee may request, from time to time, that the Corporation deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture;

(12) the Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including without limitation, acts of God; earthquakes; fires; floods; wars; civil or military disturbances; sabotage; epidemics, riots; interruptions, loss or malfunctions of utilities, computer (hardware or software) or communications service; accidents; labor disputes; acts of civil or military authority or governmental actions; it being understood that the Trustee shall use its best efforts to resume performance as soon as practicable under the circumstances; and

(13) the permissive rights of the Trustee enumerated herein shall not be construed as duties.

The Trustee shall not be deemed to have knowledge of any Default or Event of Default unless written notice of any event which is in fact such a Default or Event of Default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

Unless it is specifically required to do so pursuant to the terms of the Indenture, the Trustee shall have no obligation to make any calculations set forth in this Indenture.

SECTION 604. Trustee Not Responsible for Recitals or Issuance of Securities.

The recitals contained herein and in the Securities, except for the Trustee’s certificates of authentication, shall be taken as the statements of the Corporation, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that any statements made by it in a Statement of Eligibility on Form T-1 supplied to the Corporation are true and accurate, subject to the qualifications set forth therein. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Corporation of Securities or the proceeds thereof.

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Corporation or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Corporation with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. A Trustee that has resigned or was removed shall remain subject to Section 311(a) of the Trust Indenture Act.

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Corporation.

(1) to pay to the Trustee from time to time such compensation as the Trustee and the Corporation shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense (including, without limitation, the reasonable compensation and the expenses and disbursements of its agents and counsel) incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, the performance of its duties hereunder and/or the exercise of its rights hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder.

The obligations of the Corporation under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. As security for the performance of such obligations of the Corporation, the Trustee shall have a claim prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (or premium, if any) or interest, if any, on particular Securities.

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(5), the expenses (including reasonable charges and expense of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable U.S. or Canadian federal, state or provincial bankruptcy, insolvency or other similar law.

The provisions of this Section shall survive the termination of this Indenture, the payment of the Securities and the resignation or removal of the Trustee.

There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee under Section 310(a)(1) of the Trust Indenture Act and shall have a combined capital and surplus (together with that of its parent) of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 610.

(b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Corporation. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may, at the expense of the Corporation, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(c) The Trustee may be removed on not less than fifteen (15) days prior written notice at any time with respect to the Securities of any series by Act of the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Corporation.

(1) the Trustee shall acquire any conflicting interest as defined in Section 310(b) of the Trust Indenture Act and fail to comply with the provisions of Section 310(b)(i) of the Trust Indenture Act, or

(2) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act after written request therefor by the Corporation or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(3) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by the Corporation or by any Holder who has been a bona fide Holder of a Security for at least six months, or

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

then, in any such case, (i) the Corporation may remove the Trustee with respect to all Securities or the Securities of such series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities of such series and the appointment of a successor Trustee or Trustees. The following indentures shall be deemed to be specifically described herein for the purposes of clause (i) of the second provision contained in Section 310(b) of the Trust Indenture Act: Indenture, dated as of September 18, 2009, between the Corporation and The Bank of New York Mellon, as trustee; and Indenture, dated as of August 17, 2012, between the Corporation and The Bank of New York Mellon, as trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Corporation, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the

Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Corporation and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Corporation. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Corporation or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(f) The Corporation shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to the Holders of Securities of such series in the manner provided for in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Corporation and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Corporation or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Corporation, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in

the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Corporation or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. Whenever there is a successor Trustee with respect to one or more (but less than all) series of Securities issued pursuant to this Indenture, the terms “Indenture” and “Securities” shall have the meanings specified in the provisos to the respective definitions of those terms in Section 101 which contemplate such situation.

(c) Upon request of any such successor Trustee, the Corporation shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. In case any of the Securities shall not have been authenticated by such predecessor Trustee, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

At any time when any of the Securities remain Outstanding, the Trustee may authorize an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series and the Trustee shall give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 106. Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such authorization shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Corporation. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Corporation and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Corporation. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Corporation. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may authorize a successor Authenticating Agent which shall be acceptable to the Corporation and shall give written notice of such authorization to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 106. Any successor Authenticating Agent upon acceptance of its authorization hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be authorized unless eligible under the provisions of this Section.

The Corporation agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section.

If an authorization with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Securities of the series designated and referred to in, and issued under, the within-mentioned Indenture.


THE BANK OF NEW YORK MELLON, as Trustee

By
		as Authenticating Agent

By
		Authorized Signatory

The Corporation will furnish or cause to be furnished to the Trustee (1) not more than 15 days after each Regular Record Date a list, in such form as the Trustee may reasonably require, of the names and addresses of Holders of the Securities as of such Regular Record Date; provided, however, that the Corporation shall not be obligated to furnish or cause to be furnished such list at any time that the list shall not differ in any respect from the most recent list furnished to the Trustee by the Corporation and at such times as the Trustee is acting as Security Registrar for the applicable series of Securities and (2) at such other times as the Trustee may request in writing within 30 days after the receipt by the Corporation of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished.

The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders of the Securities contained in the most recent list furnished to it as provided in Section 701 and as to the names and addresses of Holders of the Securities received by the Trustee in its capacity as Security Registrar for the applicable series of Securities (if acting in such capacity).

The Trustee may destroy any list furnished to it as provided in Section 701 upon receipt of a new list so furnished.

Holders may communicate as provided in Section 312(b) of the Trust Indenture Act with other Holders with respect to their rights under this Indenture or under the Securities.

Every Holder of Securities, by receiving and holding the same, agrees with the Corporation and the Trustee that none of the Corporation or the Trustee or any agent of either of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Section 312 of the Trust Indenture Act, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under Section 312(b) of the Trust Indenture Act.

(a) Within 60 days after May 15 of each year commencing with the first May 15 after the first issuance of Securities pursuant to this Indenture, the Trustee shall transmit to the Holders of the Securities, in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, a brief report dated as of such May 15 if required by Section 313(a) of the Trust Indenture Act.

(b) The Trustee shall comply with Sections 313(b) and 313(c) of the Trust Indenture Act.

(c) A copy of such report shall, at the time of such transmission to the Holders of the Securities, be filed by the Trustee with the Corporation (Attention: General Counsel), with each securities exchange upon which any of the Securities are listed (if so listed) and also with the Commission. The Corporation agrees to notify the Trustee in writing when the Securities become listed on any stock exchange.

(a) file with the Trustee, within 30 days after the Corporation files or furnishes the same with or to the Commission, copies, which may be in electronic format, of the annual and quarterly reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which the Corporation may be required to file with or furnish to the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act;

(b) file with the Trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such additional information, documents and reports with respect to compliance by the Corporation with the conditions and covenants of this Indenture as may be required from time to time by such rules and regulations;

(c) notwithstanding that the Corporation may not be required to remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the Commission, the Corporation shall provide the Trustee:

(i) within 140 days after the end of each fiscal year, the information required to be contained in annual reports on Form 20-F, Form 40-F or Form 10-K as applicable (or any successor form); and

(ii) within 65 days after the end of each of the first three fiscal quarters of each fiscal year, the information required to be contained in reports on Form 6-K (or any successor form) which, regardless of applicable requirements, shall, at a minimum, contain such information required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a corporation with securities listed on the Toronto Stock Exchange, whether or not the Corporation has any of its securities so listed.

Such reports, to the extent permitted by the rules and regulations of the Commission, may be prepared in accordance with Canadian disclosure requirements and GAAP; provided, however, that the Corporation shall not be obligated to file such reports with the Commission if the Commission does not permit such filings;

(d) transmit to all Holders, in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, within 30 days after the filing thereof with the Trustee, such summaries of any information, documents and reports required to be filed by the Corporation pursuant to paragraphs (a) and (b) of this Section as may be required by rules and regulations prescribed from time to time by the Commission; and

(e) for so long as any series of Securities are not freely tradeable under the Securities Act, if at any time the Corporation is not required to file with the SEC the reports required by this Section 705, furnish to the Holders, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) of the Securities Act.

Delivery of such reports, information and documents to the Trustee shall be for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Corporation’s compliance with any of the covenants contained in this Indenture (as to which the Trustee is entitled to conclusively rely upon an Officer’s Certificate).

The Corporation shall not consolidate or amalgamate with or merge into or enter into any statutory arrangement with any other corporation, partnership or trust, or convey, transfer or lease all or substantially all of its properties and assets to any Person, unless:

(1) the entity formed by or continuing from such consolidation or amalgamation or into which the Corporation is merged or with which the Corporation enters into such statutory arrangement or the Person which acquires or leases, all or substantially all of the Corporation’s properties and assets (A) shall be a corporation, partnership or trust organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia or the laws of Canada or any province or territory thereof, or, if such consolidation, amalgamation, merger, statutory arrangement or other transaction would not impair the rights of Holders, in any other country, provided that if such successor entity is organized under the laws of a jurisdiction other than the United States, any state thereof or the District of Columbia, or the laws of Canada or any province or territory thereof, the successor entity assumes the Corporation’s obligations under the Securities and this Indenture to pay Additional Amounts, with the name of such successor jurisdiction being included in addition to Canada in each place that Canada appears in Section 1005 and Section 1110 and (B) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, or shall assume by operation of law, the Corporation’s obligation for the due and punctual payment of the principal of (and premium, if any) and interest, if any, on all the Securities and the performance and observance of every covenant of this Indenture on the part of the Corporation to be performed or observed;

(2) immediately after giving effect to such transaction, no Default or Event of Default, shall have happened and be continuing; and

(3) the Corporation or such Person shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such amalgamation, statutory arrangement, consolidation, merger, conveyance, transfer or lease and such supplemental indenture comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with.

This Section shall only apply to a merger, amalgamation, statutory arrangement or consolidation in which the Corporation is not the surviving corporation and to conveyances, leases and transfers by the Corporation as transferor or lessor. For greater certainty, the Corporation shall be considered to be the surviving corporation in the event of a statutory amalgamation by the Corporation with any Subsidiary wholly-owned by it.

In addition, the Corporation may, notwithstanding anything contained in this Indenture, consolidate or amalgamate with or merge into or enter into a statutory arrangement with any direct or indirect wholly-owned Subsidiary and may convey, transfer or lease all or substantially all of the properties and assets of the Corporation to any direct or indirect wholly-owned Subsidiary without complying with the provisions in this Section 801 in a transaction or series of transactions in which the Corporation retains all of its obligations under and in respect of all Outstanding Securities (a “Permitted Reorganization”) provided that on or prior to the date of the Permitted Reorganization the Corporation delivers to the Trustee an Officer’s Certificate confirming that, as of the date of the Permitted Reorganization:

(a) substantially all of the unsubordinated and unsecured indebtedness for borrowed money of the Corporation which ranked pari passu with the then Outstanding Securities immediately prior to the proposed Permitted Reorganization will rank no better than pari passu with the then Outstanding Securities after the Permitted Reorganization; for certainty, there is no requirement for any such other indebtedness to obtain or maintain similar ranking to the then Outstanding Securities and such other indebtedness may be structurally subordinated or otherwise subordinated to the then Outstanding Securities; or

(b) at least two of the Corporation’s then current Rating Agencies (or if only one Rating Agency maintains ratings in respect of the Securities at such time, that one Rating Agency) have affirmed that the rating assigned by them to the Securities shall not be downgraded as a result of the Permitted Reorganization.

If, as a result of any such transaction, any of our or the Restricted Subsidiaries’ Restricted Properties become subject to a Lien, then, unless such Lien could be created pursuant to the provisions described herein without equally and ratably securing the Securities, the Corporation, simultaneously with or prior to such transaction, will secure, or cause the applicable Restricted Subsidiary to secure, the Securities to be secured equally and ratably with or prior to the indebtedness secured by such Lien.

Upon any amalgamation, consolidation or statutory arrangement by the Corporation with or merger by the Corporation into any other corporation, partnership or trust or any conveyance, transfer or lease of all or substantially all of the properties and assets of the Corporation to any Person in accordance with Section 801, other than a Permitted Reorganization, the successor Person formed by such amalgamation or consolidation or into which the Corporation is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Corporation under this Indenture with the same effect as if such successor Person had been named as the Corporation herein, and in the event of any such conveyance or transfer, the Corporation (which term shall for this purpose mean the Person named as the “Corporation” in the first paragraph of this Indenture or any successor Person which shall theretofore become such in the manner described in Section 801), except in the case of a lease, shall be discharged of all obligations and covenants under this Indenture and the Securities and may be dissolved and liquidated.

If, upon any such amalgamation, consolidation or statutory arrangement of the Corporation with or merger of the Corporation into any other corporation, partnership or trust or upon any conveyance, lease or transfer of all or substantially all of the property of the Corporation to any other Person, any Restricted Property of the Corporation or a Restricted Subsidiary, or any Restricted Securities owned by the Corporation immediately prior thereto, would thereupon become subject to any Lien, then unless such Lien could be created pursuant to Section 1006 without equally and ratably securing the Securities, the Corporation, prior to or simultaneously with such consolidation, amalgamation, statutory arrangement, merger, conveyance, lease or transfer, will, as to such Restricted Property or Restricted Securities, secure or cause such Restricted Subsidiary to secure the Securities Outstanding hereunder (together with, if the Corporation shall so determine, any other indebtedness of the Corporation now existing or hereafter created which is not subordinate to the Securities) equally and ratably with (or prior to) the indebtedness which upon such consolidation, amalgamation, merger, statutory arrangement, conveyance, lease or transfer is to become secured as to such Restricted Property or Restricted Securities by such Lien, or will cause such Securities to be so secured.

Without the consent of any Holders, the Corporation, when authorized by or pursuant to a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:

(1) to evidence the succession of another Person to the Corporation and the assumption by any such successor of the covenants of the Corporation contained herein and in the Securities; or

(2) to add to the covenants of the Corporation for the benefit of the Holders of all or any series of Securities (and if such covenants are to be for the benefit of less than all series of Securities, stating that such covenants are being included solely for the benefit of such series) or to surrender any right or power herein conferred upon the Corporation; or

(3) to add any additional Events of Default (and if such Events of Default are to be for the benefit of less than all series of Securities, stating that such Events of Default are being included solely for the benefit of such series); or

(4) to change or eliminate any of the provisions of this Indenture; provided that any such change or elimination shall become effective only when there is no Security Outstanding of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision; or

(5) to secure the Securities pursuant to the requirements of Section 803 or 1006 or otherwise; or

(6) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 610(b) or to comply with applicable law; or

(7) to close this Indenture with respect to the authentication and delivery of Additional Securities of any series; or

(8) to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Sections 401, 1202 and 1203; provided that any such action shall not adversely affect the interests of the Holders of Securities of such series or any other series of Securities in any material respect; or

(9) to cure any ambiguity, to correct or supplement any provision herein or in any supplemental indenture which may be inconsistent with any other provision herein or in any supplemental indenture, or to make any other provisions with respect to matters or questions arising hereunder or in any supplemental indenture; provided such action shall not adversely affect the interests of the Holders of Securities of any series in any material respect.

With the consent of the Holders of not less than a majority in principal amount of all Outstanding Securities of a series affected by such supplemental indenture, by Act of said Holders delivered to the Corporation and the Trustee, the Corporation, when authorized by or pursuant to a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture which affect such series of Securities or of modifying in any manner the rights of the Holders of the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security of such series,

(1) change the Stated Maturity of the principal of (or premium, if any) or any installment of interest on any Security of such series, or reduce the principal amount thereof (or premium, if any) or the rate of interest, if any, thereon, or change any obligation of the Corporation to pay Additional Amounts contemplated by Section 1005 (except as contemplated by Section 801(1) and permitted by Section 901(1)), or change any Place of Payment where, or the Currency in which, any Security of such series or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date or Special Mandatory Redemption Date); or

(2) reduce the percentage of principal amount of the Outstanding Securities of such series required for any such supplemental indenture, or the consent of Holders required for any waiver of compliance with certain provisions of this Indenture which affect such series or certain defaults applicable to such series hereunder and their consequences provided for in this Indenture, or reduce the requirements of Section 1304 for quorum or voting with respect to Securities of such series, or

(3) modify any of the provisions of this Section, Section 513 or Section 1009, except to increase any such percentage or to provide that certain other provisions of this Indenture which affect such series cannot be modified or waived without the consent of the Holder of each Outstanding Security of such series.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit or one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. Any such supplemental indenture adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture, or modifying in any manner the rights of the Holders of Securities of such series, shall not affect the rights under this Indenture of the Holders of Securities of any other series.

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, in addition to the documents required by Section 102, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect.

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Corporation shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Corporation, to any such supplemental indenture may be prepared and executed by the Corporation and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

Promptly after the execution by the Corporation and the Trustee of any supplemental indenture pursuant to the provisions of Section 902, the Corporation shall give notice thereof to the Holders of each Outstanding Security affected, in the manner provided for in Section 106, setting forth in general terms the substance of such supplemental indenture.

The Corporation covenants and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the principal of (and premium, if any) and interest, if any, on the Securities of that series in accordance with the terms of the Securities and this Indenture.

The Corporation will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Corporation in respect of the Securities of that series and this Indenture may be served.

The Corporation will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Corporation shall fail to maintain any such required office or agency or shall fail to furnish in writing the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Corporation may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Corporation of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Corporation will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Corporation hereby designates as a Place of Payment for each series of Securities the Corporate Trust Office in New York, New York and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in such city and as its agent to receive all such presentations, surrenders, notices and demands.

If the Corporation shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (or premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of (or premium, if any) or interest, if any, on the Securities of such series so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee in writing of its action or failure so to act.

Whenever the Corporation shall have one or more Paying Agents for any series of Securities, it will, prior to or on each due date of the principal of (or premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (or premium, if any) or interest, if any, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Corporation will promptly notify the Trustee in writing of its action or failure so to act.

The Corporation will cause each Paying Agent (other than the Trustee) for any series of Securities to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will:

(1) hold all sums held by it for the payment of the principal of (and premium, if any) and interest, if any, on Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee written notice of any default by the Corporation (or any other obligor upon the Securities of such series) in the making of any payment of principal of (or premium, if any) or interest, if any, on the Securities of such series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Corporation may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Corporation Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Corporation or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which sums were held by the Corporation or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Except as provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or then held by the Corporation, in trust for the payment of the principal of (or premium, if any) or interest, if any, on any Security of any series, and remaining unclaimed for two years (or such shorter period as may be specified in the applicable abandoned property statutes) after such principal, premium or interest has become due and payable shall be

paid to the Corporation on Corporation Request, or (if then held by the Corporation) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Corporation for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Corporation as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Corporation cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Corporation.

The Corporation will deliver to the Trustee, within 140 days after the end of each fiscal year, a brief certificate from the Chief Executive Officer, the Chief Financial Officer, the Controller, or the Treasurer of the Corporation as to his or her knowledge of the Corporation’s compliance with all conditions and covenants under this Indenture. For purposes of this Section 1004, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(a) All payments made by or on behalf of the Corporation under or with respect to the Securities of any series will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or of any province or territory thereof or by any authority or agency therein or thereof having power to tax (hereinafter “Canadian Taxes”), unless the Corporation is required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof. If the Corporation is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Securities, the Corporation will pay to each Holder as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder (including the Additional Amounts) after such withholding or deduction (and after deducting any Canadian Taxes on such Additional Amounts) will not be less than the amount the Holder would have received if such Canadian Taxes had not been withheld or deducted. However, no Additional Amounts will be payable with respect to a payment made to a Holder in respect of the beneficial owner thereof (such Holder or beneficial owner, an “Excluded Holder”):

(1) with which the Corporation does not deal at arm’s length for the purposes of the Income Tax Act (Canada) at the time the amount is paid or payable;

(2) which is subject to such Canadian Taxes by reason of the Holder or beneficial owner being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with Canada or any province thereof otherwise than by the mere holding of Securities or the receipt of payments thereunder; or

(3) which is subject to such Canadian Taxes by reason of the Holder’s or beneficial owner’s failure to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes.

In addition, Additional Amounts will not be payable if the beneficial owner of, or person ultimately entitled to obtain an interest in, such Securities is not the sole beneficial owner of such payments, or is a fiduciary or partnership, to the extent that any beneficial owner, beneficiary or settlor with respect to such fiduciary or any partner or member of such partnership would not have been entitled to such Additional Amounts with respect to such payments had such beneficial owner, beneficiary, settlor, partner or member received directly its beneficial or distributive shares of such payments. In addition, Additional Amounts will not be payable with respect to any Canadian Taxes which are payable otherwise than by withholding from payments of, or in respect of, principal of, or interest on, the Securities.

(ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

The Corporation will furnish to the Holders of the Securities, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by the Corporation.

(b) The Corporation will indemnify and hold harmless each Holder in respect of the beneficial owner (other than an Excluded Holder) and, upon written request, reimburse each such Holder for the amount excluding any of Additional Amounts that have been previously been paid by the Corporation with respect thereto of:

(1) the payment of any Canadian Tax, together with any interest, penalties and reasonable expenses in connection therewith; and

(2) any Canadian Taxes imposed with respect to any reimbursement under clause (1) in this paragraph, but excluding any such Canadian Taxes on such Holder’s net income.

At least five (5) days prior to each date on which any payment under or with respect to the Securities is due and payable, if the Corporation will be obligated to pay Additional Amounts with respect to such payment, the Corporation will deliver to the Trustee an Officer’s Certificate stating the fact that such Additional Amounts will be payable and specifying the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date.

Notwithstanding the foregoing, provided that the Corporation (or any successor) is an entity organized under the laws of the United States of America, any state thereof, or the District of Columbia, or the laws of Canada or any province or territory thereof, no Additional Amounts or indemnity amounts will be payable in excess of Additional Amounts or indemnity amounts which would be required if the Holder of the Securities was a resident of the United States and a “qualifying person” for purposes of the Canada-U.S. Income Tax Convention (1980), as amended.

Wherever in this Indenture or the Securities there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount payable under or with respect to a Security, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

So long as any Securities are Outstanding and subject to the terms of this Indenture, the Corporation will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise have outstanding any Lien securing any indebtedness for borrowed money or interest thereon (or any liability of the Corporation or such Restricted Subsidiaries under any guarantee or endorsement or other instrument under which the Corporation or such Restricted Subsidiaries are contingently liable, either directly or indirectly, for borrowed money or interest thereon), other than Permitted Liens, without also simultaneously or prior thereto securing, or causing such Restricted Subsidiaries to secure, indebtedness under this Indenture so that the Securities are secured equally and ratably with or prior to such other indebtedness or liability, except that the Corporation and its Restricted Subsidiaries may incur a Lien to secure indebtedness for borrowed money without securing the Securities if, after giving effect thereto, the principal amount of indebtedness for borrowed money secured by Liens created, incurred or assumed after the date hereof and otherwise prohibited by this Indenture does not exceed 12% of the Corporation’s Consolidated Net Tangible Assets.

Notwithstanding the foregoing, transactions such as the sale (including any forward sale) or other transfer of: (i) oil, gas, minerals or other resources of a primary nature, whether in place or when produced, for a period of time until, or in an amount such that, the purchaser will realize therefrom a specified amount of money or a specified rate of return (however determined), or a specified amount of such oil, gas, minerals, or other resources of a primary nature, or (ii) any other interest in property of the character commonly referred to as a “production payment”, will not constitute a Lien and will not result in the Corporation or a Restricted Subsidiary being required to secure the Securities.

The Corporation will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon the Corporation or any Restricted Subsidiary or upon the income, profits or property of the Corporation or any Restricted Subsidiary; provided, however, that the Corporation shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

Subject to Article Eight, the Corporation will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the rights (charter and statutory) and franchises of the Corporation and any Restricted Subsidiary; provided, however, that the Corporation shall not be required to preserve any such right or franchise if the Corporation shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Corporation and its Subsidiaries as a whole.

The Corporation may, with respect to any series of Securities, omit in any particular instance to comply with any term, provision or condition which affects such Securities set forth in Section 803 or Sections 1006 through 1008 inclusive, if before the time for such compliance the Holders of at least a majority in principal amount of all Outstanding Securities of any series, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Corporation and the duties of the Trustee to Holders of Securities of such series in respect of any such term, provision or condition shall remain in full force and effect.

On the date of this Indenture, (i) the Corporation shall deposit (or cause to be deposited) into the Escrow Account cash in the amount sufficient to pay in full the Special Mandatory Redemption Price for the Securities on the latest possible Special Mandatory Redemption Date and (ii) the Corporation, the Trustee and the Escrow Agent shall enter into the Escrow and Security Agreement. The Corporation hereby expressly directs the Trustee to enter into the Escrow and Security Agreement.

The Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with the terms of such Securities and (except as otherwise specifically contemplated by Section 301 for Securities of any series) in accordance with this Article.

Prior to the Applicable Par Call Date, the Securities of each series will be redeemable, in whole or in part, at the option of the Corporation at any time or from time to time, at a Redemption Price equal to the greater of:

(2) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed that would be due if such series of Securities matured on the Applicable Par Call Date (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus the Applicable Spread for such series of Securities, plus, in each case, accrued interest thereon to the Redemption Date.

On or after the Applicable Par Call Date, the Securities of each series will be redeemable, in whole or in part, at a redemption price equal to 100% of the principal amount of such series of the Securities to be redeemed, plus, in each case, accrued and unpaid interest thereon to the Redemption Date.

If, on or before the Transaction Closing Deadline, (1) the Acquisition is not consummated on substantially the terms described in the Final Offering Memorandum or (2) the Corporation notifies the Escrow Agent and the Trustee in writing or publicly announces that it will not proceed with the Acquisition for any reason, the Corporation will cause to be redeemed the Securities then outstanding, in whole and not in part, on or prior to the Special Mandatory Redemption Date (the “Special Mandatory Redemption”). In the event of a Special Mandatory Redemption, the “Special Mandatory Redemption Price” will be equal to 101% of the aggregate principal amount of the Securities plus accrued interest to, but not including, the Special Mandatory Redemption Date.

The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Corporation, the Corporation shall, at least 60 days prior to the Redemption Date fixed by the Corporation (unless a shorter notice shall be satisfactory to the Trustee), except in the case of a Special Mandatory Redemption pursuant to Section 1103, in which case such notice shall be given not less than five days prior to the Special Mandatory Redemption Date, notify the Trustee in writing of such Redemption Date and of the principal amount of the Securities of such series to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 1105. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Corporation shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction.

In the case of a partial redemption of Securities, selection of such Securities for redemption will be made in accordance with DTC procedures. If any Security is redeemed in part, the notice of redemption relating to such Security shall state the portion of the principal amount thereof to be redeemed; provided that no Security in an aggregate principal amount of US$2,000 or less shall be redeemed in part. A replacement Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Security.

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 redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

Notice of redemption shall be given in the manner provided for in Section 106, and shall be given not less than 10 nor more than 60 days prior to the Redemption Date, except in the case of a Special Mandatory Redemption pursuant to Section 1103, in which case such notice shall be given not less than five days prior to the Special Mandatory Redemption Date, to each Holder of Securities to be redeemed. Failure to give notice in the manner provided in Section 106 to the Holder of any Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

(1) the Redemption Date or, in the case of a Special Mandatory Redemption, the Special Mandatory Redemption Date,

(2) the Redemption Price and the amount of accrued interest to the Redemption Date, or, in the case of a Special Mandatory Redemption, the Special Mandatory Redemption Price, payable as provided in Section 1108, if any,

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

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that on the Redemption Date, the Redemption Price and accrued interest, if any, to the Redemption Date payable as provided in Section 1108 will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, and

(6) the Place or Places of Payment where such Securities maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any.

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

At or prior to 10:00 a.m. (New York time) on any Redemption Date, the Corporation shall deposit with the Trustee or with a Paying Agent (or, if the Corporation 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, and accrued interest, if any, on all the Securities which are to be redeemed on that date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, (a) on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued interest, if any, to the Redemption Date), or, (b) in the case of a Special Mandatory Redemption, on the Special Mandatory Redemption Date, become due and payable at the Special Mandatory Redemption Price as provided in Section 1103, and from and after such date (unless the Corporation shall default in the payment of the Redemption Price and accrued interest, if any, or the Special Mandatory Redemption Price, as the case may be) such Securities shall cease to bear interest. In the case of a redemption pursuant to Section 1102, upon surrender of any such Security for redemption in accordance with said notice such Security shall be paid by the Corporation at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, that installments of interest on the 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 at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate of interest set forth in such Security.

Any Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered at a Place of Payment therefor (with, if the Corporation or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Corporation and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Corporation shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

The Corporation shall have the right to redeem, at any time, the Securities of a series, in whole and not in part, at a redemption price equal to the principal amount thereof together with accrued and unpaid interest to the date fixed for redemption, upon the giving of a notice as described below, if (1) the Corporation (or its successor) determines that (a) as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of Canada or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after (i) April 4, 2017 or (ii) if applicable, the date a Person organized in a jurisdiction other than Canada or the United States becomes the Corporation’s successor pursuant to Section 801, the Corporation or such successor reasonably determines that it has or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts pursuant to Section 1005 or (b) on or after (i) April 4, 2017 or (ii) if applicable, the date a Person organized in a jurisdiction other than Canada or the United States becomes the Corporation’s successor pursuant to Section 801, any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in Canada, or any political subdivision or taxing authority thereof or therein, including any of those actions specified in (a) above, whether or not such action was taken or decision was rendered with respect to the Corporation, or such successor, or any change, amendment, application or interpretation shall be officially proposed, which, in any such case, in the Opinion of Counsel to the Corporation, will likely result in the Corporation or such successor becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any Security of such series and (2) in any such case, the Corporation, or such successor, in its business judgment determines that such obligation cannot be avoided by the use of reasonable measures available to the Corporation, or such successor; provided, however, that (i) no such notice of redemption may be given earlier than 60 or later than 10 days prior to the earliest date on which the Corporation would be obligated to pay such Additional Amounts were a payment in respect of the Securities then due, and (ii) at the time such notice of redemption is given, such obligation to pay such Additional Amounts remains in effect.

SECTION 1201. Corporation’s Option to Effect Defeasance or Covenant Defeasance.

The Corporation may, at its option, effect defeasance (as defined below) of the Securities of or within a series under Section 1202, or covenant defeasance (as defined below) of or within a series under Section 1203 in accordance with the terms of such Securities and in accordance with this Article.

Upon the Corporation’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in Section 1204 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Corporation shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities, which shall

thereafter be deemed to be “Outstanding” only for the purposes of Section 1205 and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Corporation, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on such Securities when such payments are due, (B) the Corporation’s obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1005, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Corporation’s obligation under Section 607 and (D) this Article Twelve. Subject to compliance with this Article Twelve, the Corporation may exercise its option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203 with respect to such Securities.

Upon the Corporation’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be released from its obligations under Section 803 and Sections 1006 through 1008 inclusive with respect to such Outstanding Securities on and after the date the conditions set forth in Section 1204 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Corporation may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(3) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

The following shall be the conditions to application of either Section 1202 or Section 1203 to any Outstanding Securities of or within a series:

(1) The Corporation shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Article Twelve applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) an amount in cash, or (B) Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal

of (and premium, if any), and interest, if any, under such Securities, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants (which shall be expressed in a written certification thereof delivered to the Corporation, that is attached to an Officer’s Certificate delivered to the Trustee), to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of (and premium, if any) and interest, if any, on such Outstanding Securities on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of interest, if any; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to said payments with respect to such Securities. Before such a deposit, the Corporation may give to the Trustee, in accordance with Section 1102 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such series and Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(2) No Default or Event of Default with respect to such Securities shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs (5) and (6) of Section 501 are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(3) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Corporation is a party or by which it is bound.

(4) In the case of an election under Section 1202, the Corporation shall have delivered to the Trustee an Opinion of Counsel in the United States stating that (x) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of execution of this Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(5) The Corporation shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 1202 or the covenant defeasance under Section 1203 (as the case may be) have been complied with.

(6) In the case of an election under Section 1203, the Corporation shall have delivered to the Trustee an Opinion of Counsel in the United States to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

(7) Either the Corporation has delivered to the Trustee an Opinion of Counsel in Canada or an advance tax ruling from Canada Revenue Agency (or successor agency) to the effect that the Holders of such Outstanding Securities should not recognize income, gain or loss for Canadian federal or provincial income tax purposes as a result of such defeasance or covenant defeasance and should be subject to Canadian federal or provincial income tax on the same amounts, in the same manner and at the same times as would have been the case had such defeasance not occurred (and for the purposes of such opinion, such Canadian counsel shall assume that Holders of the Securities include Holders who are not resident in Canada).

(8) The Corporation is not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada) on the date of such deposit or at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(9) The Corporation has delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the Investment Company Act of 1940, as amended.

SECTION 1205. Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions.

Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of such Outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Corporation acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Corporation shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities.

Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver or pay to the Corporation from time to time upon Corporation Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 1204 which, in the opinion of, a nationally recognized firm of independent public accountants (evidenced by an Officer’s Certificate) delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article.

If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 1205 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Corporation’s obligations under this Indenture and such Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 1202 or 1203, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1205; provided, however, that if the Corporation makes any payment of principal of (or premium, if any) or interest, if any, on any such Security following the reinstatement of its obligations, the Corporation shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

A meeting of Holders of one or more series of Securities may be called at any time and from time to time pursuant to this Article to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Securities of such series.

(a) The Trustee may at any time call a meeting of Holders of Securities of any series for any purpose specified in Section 1301, to be held at such time and at such place in New York, New York or in Calgary, Alberta as the Trustee shall determine. Notice of every meeting of Holders of one or more series of Securities, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given, in the manner provided for in Section 106, not less than 21 nor more than 180 days prior to the date fixed for the meeting.

(b) In case at any time the Corporation, pursuant to a Board Resolution, or the Holders of at least 25% in principal amount of the Outstanding Securities of any series shall have requested the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified in Section 1301, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have made the first publication of the notice of such meeting within 21 days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Corporation or the Holders of Securities of such series in the amount above specified, as the case may be, may determine the time and the place in New York, New York or in Calgary, Alberta for such meeting and may call such meeting for such purposes by giving notice thereof as provided in paragraph (a) of this Section.

To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall be (1) a Holder of one or more Outstanding Securities of such series, or (2) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of such series by such Holder of Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders of Securities of any series shall be the Person entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Corporation and its counsel.

The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders of Securities of such series; provided, however, that, if any action is to be taken at such meeting with respect to a consent or waiver which this Indenture expressly provides may be given by the Holders of not less than a specified percentage in principal amount of the Outstanding Securities of a series, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series shall constitute a quorum. In the absence of a quorum within 30 minutes of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series, be dissolved. In any other case the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 1302(a), except that such notice need be given only once not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of any adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series which shall constitute a quorum.

Subject to the foregoing, at the reconvening of any meeting adjourned for lack of a quorum, the Persons entitled to vote 25% in principal amount of the Outstanding Securities at the time shall constitute a quorum for the taking of any action set forth in the notice of the original meeting.

Except as limited by the proviso to Section 902, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted by the affirmative vote of the Holders of not less than a majority in principal amount of the Outstanding Securities of such series who have cast their votes; provided, however, that, except as limited by the proviso to Section 902, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action which this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of not less than such specified percentage in principal amount of the Outstanding Securities of such series.

Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section shall be binding on all the Holders of Securities of such series, whether or not present or represented at the meeting.

Notwithstanding the foregoing provisions of this Section 1304, if any action is to be taken at a meeting of Holders of Securities of any series with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage in principal amount of all Outstanding Securities affected thereby, or of the Holders of such series and one or more additional series:

(ii) the principal amount of the Outstanding Securities of such series that vote in favor of such request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or taken under this Indenture.

SECTION 1305. Determination of Voting Rights; Conduct and Adjournment of Meetings.

(a) Notwithstanding any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct, including, without limitation, the location and period for notification, of the meeting as its shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 104 or other proof.

(b) The Trustee shall, by an instrument in writing appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Corporation or by Holders of the Securities as provided in Section 1302(b), in which case the Corporation or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting.

(c) At any meeting each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of Outstanding Securities of such series held or represented by him (determined as specified in the definition of “Outstanding” in Section 101); provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

(d) Any meeting of Holders of the Securities of any series duly called pursuant to Section 1302 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice.

The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers, if any, of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of the Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 1302 and, if applicable, Section 1304. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Corporation, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

This Indenture may be executed in any number of counterparts (either by facsimile or by original manual signature) each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Indenture.

The parties hereto acknowledge that, in accordance with Section 326 of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (as amended, modified or supplemented from time to time, the “USA Patriot Act”), the Trustee, like all financial institutions, is required to obtain, verify, and record information that identifies each person or legal entity that opens an account. The parties to this Agreement agree that they will provide the Trustee with such information as the Trustee may request in order for the Trustee to satisfy the requirements of the USA Patriot Act.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of the day and year first above written.
