SECTION 104. Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by Holders of the Outstanding Securities of all series or one or more series, as the case may be, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents
duly appointed in writing. If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of such series
may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly
called and held in accordance with the provisions of Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or
record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as
the “Act” of the Holders signing 

  
 16 

 
such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1506. 
 (b) The fact and date of the execution by any Person of any such instrument or writing may
be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to
him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such
instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 

(c) The principal amount and serial numbers of Registered Securities held by any Person, and the date of holding the same,
shall be proved by the Security Register. 
 (d) The principal amount and serial numbers of Bearer Securities held by any
Person, and the date of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary, wherever situated, if such certificate shall be
deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another
certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange
for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved in any other manner that the
Trustee deems sufficient. 
 (e) If the Company shall solicit from the Holders of Registered Securities any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be
a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of 

  
 17 

 
record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have
authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date. 

(f) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall
bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 SECTION 105. Notices, etc. to
Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other documents
provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the
Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention; Corporate Trust Administration, or 

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if
in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by
the Company. 
 SECTION 106. Notice to Holders; Waiver. 

Where this Indenture provides for notice of any event to Holders of Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date,
and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer 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 Registered Securities when such notice is required to be given pursuant to any provision of this 

  
 18 

 
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. 

Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 301, where this
Indenture provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper in New York, New York and in such other city or cities as may
be specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice. Any such notice shall be deemed to
have been given on the date of the first such publication. 
 In case, by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause, it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the
approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published,
shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the sufficiency of any notice to Holders of Registered Securities given as provided herein. 

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. 

SECTION 107. Effect of Headings and Table of Contents. 

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

SECTION 108. Successors and Assigns. 

All covenants and agreements in this Indenture by the Company and the Trustee shall bind their successors and assigns, whether so expressed or
not. 
 SECTION 109. Seperability Clause. 

In case any provision in this Indenture or in any Security or coupon 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. 

  
 19 

 SECTION 110. Benefits of Indenture. 

Nothing in this Indenture or in the Securities or coupons, 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 or coupons, any benefit or any legal or equitable right, remedy or claim under this Indenture. 

SECTION 111. Governing Law. 

This Indenture and the Securities and coupons 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. 

SECTION 112. Legal Holidays. 

In any case where any Interest Payment Date, Redemption Date, sinking fund payment 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 or coupon 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 or Redemption Date or sinking fund payment 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, sinking fund payment date. Stated Maturity or Maturity, as the case may be. 
 SECTION 113. Agent for Service;
Submission to Jurisdiction; Waiver of Immunities. 
 By the execution and delivery of this Indenture, the Company (i) acknowledges
that it has irrevocably designated and appointed CT Corporation System, 111 8th Avenue, 13th 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 Company (mailed or delivered to the Company, 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 Company in any such suit or proceeding. The Company 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. 

  
 20 

 To the extent that the Company 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 Company hereby irrevocably waives such immunity in
respect of its obligations under this Indenture and the Securities, to the extent permitted by law. 
 The Company 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. 
 SECTION 114. Conversion of Currency. 

(a) The Company 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 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
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 Company 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 Company 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 Company 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 Company 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 Company may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto. 

  
 21 

 (c) The obligations contained in Subsections (a)(2) and (b) of this Section
shall constitute separate and independent obligations of the Company from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Company, 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 Company 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 Company 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 noon rate for purchases on the relevant date of the Required Currency with the Judgment Currency, as reported on the “Exchange Rates—Daily noon rates” page of the website of Bank of
Canada (or by such other means of reporting the Bank of Canada noon rate as may be agreed upon by each of the parties to this Indenture) and includes any premiums and costs of exchange payable. 

SECTION 115. Currency Equivalent. 

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

SECTION 116. Incorporators, Shareholders, Officers and Directors of the Company Exempt from Individual Liability. 

No recourse under or upon any obligation, covenant or agreement contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any incorporator, as such, or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under
any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the
Holders as part of the consideration for the issue of the Securities. 

  
 22 

 SECTION 117. Conflict with the Trust Indenture Act. 

If and to the extent that any provision hereof limits, qualifies or conflicts with the duties imposed by any of Sections 310 to 318, inclusive,
of the Trust Indenture Act, through operation of Section 318(c) thereof, such imposed duties shall control.

accordance with, in addition to or in lieu of any of the provisions of Section 312; 
 (14) the designation of the initial Exchange Rate
Agent, if any; 
 (15) the applicability, if any, of Sections 1402 and/or 1403 to the Securities of the series and any provisions in

 (17) any deletions from, modifications of or additions to the Events of Default or

 (19) the date as of which any Bearer

charge and, if so, whether the Company will have the option to redeem such Securities rather than pay such Additional Amounts (and the terms of any such option); 

  
 27 

 (24) if the Securities of the series are to be convertible into or exchangeable for any debt
securities of any Person (including the Company), the terms and conditions upon which such Securities will be so convertible or exchangeable; 

(25) if payment of the Securities will be guaranteed by any other Person; 

(26) the extent and manner, if any, to which payment on or in respect of the Securities of the series will be senior or will be subordinated to
the prior payment of other liabilities and obligations of the Company; and 
 (27) any other terms, conditions, rights and preferences (or
limitations on such rights and preferences) relating to the series (which terms shall not be inconsistent with the requirements of the Trust Indenture Act or the provisions of this Indenture). 

All Securities of any one series and the coupons appertaining to any Bearer Securities of such series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to a Board Resolution (subject to Section 303) and set forth in such Officer’s Certificate or in any such indenture
supplemental hereto. The Company may, from time to time, without notice or consent of the Holders, create and issue additional Securities of a series so that such additional Securities may be consolidated and form a single series with the Securities
of the same series initially issued by the Company and shall have the same terms as to status, redemption and otherwise as the Securities of the same series originally issued. 

If any of the terms of the series are established by action taken pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of the series. 
 SECTION
302. Denominations. 
 The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by
Section 301. With respect to Securities of any series denominated in Dollars, in the absence of any such provisions, the Registered Securities of such series, other than Registered Securities issued in global form (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral multiple thereof and the Bearer Securities of such series, other than the Bearer Securities issued in global form (which may be of any denomination), shall be issuable in a
denomination of $5,000. 
 SECTION 303. Execution, Authentication, Delivery and Dating. 

The Securities and any coupons appertaining thereto shall be executed on behalf of the Company 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
or coupons 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. 

  
 28 

 Securities or coupons bearing the manual or facsimile signatures of individuals who were at any
time the proper officers of the Company shall bind the Company, 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 or coupons. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may
deliver Securities of any series together with any coupon appertaining thereto, executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in
accordance with such Company Order shall authenticate and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the
United States; and provided further, that, unless otherwise specified with respect to any series of Securities pursuant to Section 301, a Bearer Security may be delivered in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in Exhibit A-1 to this Indenture, dated no earlier than 15 days prior to the earlier of the date on which such Bearer Security is delivered and the
date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security, then,
for purposes of this Section and Section 304, the notation of a beneficial owner’s interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner’s interest in such permanent global Security. Except as permitted by Section 306, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and cancelled. If not all the Securities of any series are to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Company
Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, stated maturity, date of issuance and date from which interest shall
accrue. 
 In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to TIA Sections 315(a) through 315(d)) shall be fully protected in relying upon, one or more Opinions of Counsel stating: 

(a) if the form of such Securities has been established by or pursuant to a Board Resolution or in one or more indentures
supplemental hereto as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; 

(b) if the terms of such Securities have been established by or pursuant to one or more Board Resolutions or established in one
or more indentures supplemental hereto as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 

  
 29 

 (c) that such Securities, together with any coupons appertaining thereto, when
completed by appropriate insertions and executed and delivered by the Company 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 Company
in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legal, valid and binding obligations of the Company, 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. 

Notwithstanding the provisions of Section 301 and of the preceding two paragraphs, if not all the Securities of any series are to be
issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to the preceding two paragraphs prior to
or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series. 

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. 

Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as
contemplated by Section 301. 
 No Security or coupon 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 Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 310 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 Company, 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. 
 SECTION 304. Temporary Securities. 

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in
registered form or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as conclusively the officers executing such Securities may determine,
as 

  
 30 

 
conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form. 

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor
a like principal amount of definitive Securities of the same series of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and
provided further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 303. Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
 If temporary
Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London, England office of a depositary or common depositary (the “Common
Depositary”) or the Depositary, as applicable, for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct). 

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary
global Security (the “Exchange Date”), the Company shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or
after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company’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 temporary 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 temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global bearer form or permanent
global registered form, or any combination thereof, as specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euroclear as to the
portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global Security held for its account
then to be exchanged, each in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established 

  
 31 

 
pursuant to Section 301); and provided further, that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security only in compliance
with the requirements of Section 303. 
 Unless otherwise specified in such temporary global Security, the interest of a beneficial
owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or Clearstream, as the case may
be, to request such exchange on his behalf and delivers to Euroclear or Clearstream, as the case may be, a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 301),
dated no earlier than 15 days prior to the Exchange Date, copies of which certificate shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying
Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost
of insurance, postage, transportation and the like in the event that such Person does not take delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in
exchange for any portion of a temporary global Security shall be delivered only outside the United States. 
 Until exchanged in full as
hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except
that, unless otherwise specified as contemplated by Section 301, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to
Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee of a certificate or certificates in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established
pursuant to Section 301), for credit without further interest thereon on or after such Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date
and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date in the form set forth in Exhibit A-1 to this Indenture
(or in such other form as may be established pursuant to Section 301). Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding
two paragraphs of this Section and of the third paragraph of Section 303 of this Indenture and the interests of the Persons who are the beneficial owners of the temporary global Security with respect to which such certification was made will be
exchanged for definitive Securities of the same series and of like principal amount and tenor and evidencing the same indebtedness on the Exchange Date or the date of certification if such date occurs after the Exchange Date, without further act or
deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or interest, if any, owing with respect to a beneficial interest in a temporary global Security will be made unless and
until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear and Clearstream and not paid as herein provided shall be returned to the Trustee
immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company in accordance with Section 1003. 

  
 32 

 SECTION 305. Registration, Registration of Transfer and Exchange. 

The Company 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 Company 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 Company shall provide for the registration of Registered Securities and of transfers of Registered 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 Registered Securities and transfers of Registered Securities as herein provided. The Company 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 Registered Securities shall have been appointed by the Company and shall have accepted such
appointment by the Company. 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
Registered Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee, one or more new Registered
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, Registered Securities of any series may be exchanged for other Registered 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 Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to any series of Securities as
contemplated by Section 301, Bearer Securities may not be issued in exchange for Registered Securities. 
 If (but only if) expressly
permitted in or pursuant to the applicable Board Resolution and (subject to Section 303) set forth in the applicable Officer’s Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for Registered 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
Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or
matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the

  
 33 

 
surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such
payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the
United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such
office or agency 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, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and 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 the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such
coupon when due in accordance with the provisions of this Indenture. 
 Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, 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, as specified as contemplated by Section 301 and 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 Company 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 Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other Depositary as
shall be specified in the Company Order with respect thereto to the Trustee, as the Company’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 which, unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, as specified as contemplated by Section 301, shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof; 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; and provided further, that no

  
 34 

 
Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered 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 Registered 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 Company 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 Company shall
appoint a successor Depositary with respect to the Securities for such series. If a successor to the Depositary for Securities is not appointed by the Company within 90 days after the Company 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 the Securities for such series and the Company will execute, and the Trustee,
upon receipt of a Company 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 the global Security or Securities representing such series in exchange for such global Security or Securities. 

The Company 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 Company will execute, and the Trustee, upon receipt of a Company 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 the 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. 

  
 35 

 All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company, 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 Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the
Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Company 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 Company 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, 1107 or 1305 not involving any transfer.

 The Company 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 1103 or 1203 and ending at the close of business on (A) if Securities of the series are issuable only as
Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of
the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be immediately surrendered for redemption, or (iv) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such Security not to be so repaid. 
 SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

 If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee, the Company 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, with
coupons corresponding to the coupons, if any, appertaining to the surrendered Security, or, in case any such mutilated Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new
Security, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security, pay such Security or coupon. 
 If
there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon and (ii) such security or indemnity as may be required by them to save each of them
and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or 

  
 36 

 
coupon has been acquired by a protected purchaser (as defined in Article 8 of the UCC), the Company shall execute and upon Company Order the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security or in exchange for the Security for which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), 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, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen coupon appertains. 
 Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated,
destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to such mutilated,
destroyed, lost or stolen Security or to the Security to which such mutilated, destroyed, lost or stolen coupon appertains, pay such Security or coupon; provided, however, that payment of principal of (and premium, if any) and
interest, if any, on Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, any
interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. 
 Upon the
issuance of any new Security under this Section, the Company 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 with its coupons, if any, issued pursuant to this Section in lieu of
any mutilated, destroyed, lost or stolen Security or in exchange for a Security to which a mutilated, destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security and its coupons, if any, or the mutilated, destroyed, lost or stolen coupon 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 and their coupons, if any, 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 or coupons. 

SECTION 307. Payment of Principal and Interest; Interest Rights Preserved; Optional Interest Reset. 

(a) Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name 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 Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of the principal of (and premium, if any,
on) and interest, 

  
 37 

 
if any, on any Registered Security may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto
pursuant to Section 309, to the address of such Person as it appears on the Security Register or (ii) wire transfer to an account of the person entitled to receive such payment located in the United States maintained by the payee of a
Holder of $5,000,000 or more in aggregate principal amount of the Securities of such series (with wire transfer instructions provided to the Trustee not less than 15 days prior to payment of interest by wire transfer); provided
further, that principal paid in relation to any Security redeemed at the option of the Company pursuant to Article Eleven, 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(a). 
 Unless otherwise provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest, if any, may be made, in the case of a Bearer Security, by transfer to an account located outside the United States maintained by the payee. 

Unless otherwise provided as contemplated by Section 301, every permanent global Security will provide that interest, if any, payable on
any Interest Payment Date will be paid to each of Euroclear and Clearstream with respect to that portion of such permanent global Security held for its account by the Common Depositary, for the purpose of permitting each of Euroclear and Clearstream
to credit the interest, if any, received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof. 

Any interest on any Registered 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 Company, at its election in each case, as provided in clause (1) or
(2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the
Registered 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 Company
shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of
money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e))
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 

  
 38 

 
proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be given 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 Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of
any Defaulted Interest on the Registered Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such
exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

(b) The provisions of this Section 307(b) may be made applicable to any series of Securities pursuant to Section 301
(with such modifications, additions or substitutions as may be specified pursuant to such Section 301). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series
may be reset by the Company on the date or dates specified on the face of such Security (each an “Optional Reset Date”). The Company may exercise such option with respect to such Security by notifying the Trustee of such exercise at
least 50 but not more than 60 days prior to an Optional Reset Date for such Note. Not later than 40 days prior to each Optional Reset Date, the Trustee shall transmit, in the manner provided for in Section 106, to the Holder of any such
Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new
interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset
Date, to the Stated Maturity Date of such Security (each such period a “Subsequent Interest Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may
occur during the Subsequent Interest Period. 
 Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the
Company may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or a spread or spread multiplier used to
calculate such interest rate, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustee to transmit, in the
manner provided for in Section 106, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the
interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or
have 

  
 39 

 
validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable). 

The Holder of any such Security will have the option to elect repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment
at the option of Holders except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment
pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset 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. 

SECTION 308. Optional Extension of Stated Maturity. 

The provisions of this Section 308 may be made applicable to any series of Securities pursuant to Section 301 (with such
modifications, additions or substitutions as may be specified pursuant to such Section 301). The Stated Maturity of any Security of such series may be extended at the option of the Company for the period or periods specified on the face of such
Security (each an “Extension Period”) up to but not beyond the date (the “Final Maturity”) set forth on the face of such Security. The Company may exercise such option with respect to any Security by notifying the
Trustee of such exercise at least 50 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such option (the “Original Stated Maturity”). If the Company exercises such option, the
Trustee shall transmit, in the manner provided for in Section 106, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “Extension Notice”) indicating (i) the election
of the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the interest rate, if any, applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the
Trustee’s transmittal of the Extension Notice, the Stated Maturity of such Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms
as prior to the transmittal of such Extension Notice. 
 Notwithstanding the foregoing, not later than 20 days before the Original Stated
Maturity of such Security, the Company may, at its option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in
Section 106, notice of such higher interest rate to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 

If the Company extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Company on the
Original Stated Maturity at a price equal to the principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Company has extended the Maturity thereof,

  
 40 

 
the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25
but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment
until the close of business on the tenth day before the Original Stated Maturity. 
 SECTION 309. Persons Deemed Owners. 

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of (and 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 Company, the Trustee or any agent of the Company or
the Trustee shall be affected by notice to the contrary. 
 Title to any Bearer Security and any coupons appertaining thereto shall pass by
delivery. The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or
on account thereof and for all other purposes whatsoever, whether or not such Security or coupons be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 

The Depositary for Securities may be treated by the Company, the Trustee, and any agent of the Company 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 Company, 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 Company, the Trustee, or any agent of the Company 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. 
 SECTION 310. Cancellation. 

All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or
for credit against any current or 

  
 41 

 
future sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities and coupons so delivered to the Trustee shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company 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 Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. If the Company
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 certification of their disposal delivered to the Company unless by Company Order the Company shall direct that cancelled Securities be returned to it. 

SECTION 311. Computation of Interest. 

Except as otherwise specified as contemplated by Section 301 with respect to any Securities, 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 the Interest Act (Canada), 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 periods (the “calculation period”) is equivalent is 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 period, multiplied by (B) the sum of (y) the product of 30 multiplied by the number of complete months elapsed in such period and (z) the actual number of days elapsed in any
incomplete month in such period; and (ii) the denominator is the product of (A) 360 multiplied by (B) the actual number of days in such period. 

SECTION 312. Currency and Manner of Payments in Respect of Securities. 

(a) With respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or
the Holders of which have not made the election provided for in paragraph (b) below, and with respect to Bearer Securities of any series, except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and
interest, if any, on any Registered or Bearer Security of such series will be made in the Currency in which such Registered Security or Bearer Security, as the case may be, is payable. The provisions of this Section 312 may be modified or
superseded with respect to any Securities pursuant to Section 301. 
 (b) It may be provided pursuant to
Section 301 with respect to Registered Securities of any series that Holders shall have the option, subject to paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered
Securities in any of the Currencies which may be designated for such election by delivering to the Trustee a written election with signature guarantees and in the applicable form established pursuant to Section 301, not later than the close of

  
 42 

 
business on the Election Date immediately preceding the applicable payment date. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such
Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustee (but any such change must be made not later than the close of business on the Election Date immediately preceding the next
payment date to be effective for the payment to be made on such payment date and no such change of election may be made with respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has
occurred or with respect to which the Company has deposited funds pursuant to Article Four or Fourteen or with respect to which a notice of redemption has been given by the Company or a notice of option to elect repayment has been sent by such
Holder or such transferee). Any Holder of any such Registered Security who shall not have delivered any such election to the Trustee not later than the close of business on the applicable Election Date will be paid the amount due on the applicable
payment date in the relevant Currency as provided in Section 312(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Registered Securities for which Holders
have made such written election. 
 (c) Unless otherwise specified pursuant to Section 301, if the election referred to
in paragraph (b) above has been provided for pursuant to Section 301, then, unless otherwise specified pursuant to Section 301, not later than the fourth Business Day after the Election Date for each payment date for Registered
Securities of any series, the Exchange Rate Agent will deliver to the Company a written notice specifying, in the Currency in which Registered Securities of such series are payable, the respective aggregate amounts of principal of (and premium, if
any) and interest, if any, on the Registered Securities to be paid on such payment date, specifying the amounts in such Currency so payable in respect of the Registered Securities as to which the Holders of Registered Securities of such series shall
have elected to be paid in another Currency as provided in paragraph (b) above. If the election referred to in paragraph (b) above has been provided for pursuant to Section 301 and if at least one Holder has made such election, then,
unless otherwise specified pursuant to Section 301, on the second Business Day preceding such payment date the Company will deliver to the Trustee for such series of Registered Securities an Exchange Rate Officer’s Certificate in respect
of the Dollar or Foreign Currency payments to be made on such payment date. Unless otherwise specified pursuant to Section 301, the Dollar or Foreign Currency amount receivable by Holders of Registered Securities who have elected payment in a
Currency as provided in paragraph (b) above shall be determined by the Company on the basis of the applicable Market Exchange Rate in effect on the third Business Day (the “Valuation Date”) immediately preceding each payment
date, and such determination shall be conclusive and binding for all purposes, absent manifest error. 
 (d) If a Conversion
Event occurs with respect to a Foreign Currency in which any of the Securities are denominated or payable other than pursuant to an election provided for pursuant to paragraph (b) above, then with respect to each date for the payment of
principal of (and premium, if any) and interest, if any, on the applicable Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the
Dollar shall be the Currency of payment for use on each such payment date. Unless otherwise specified 

  
 43 

 
pursuant to Section 301, the Dollar amount to be paid by the Company to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities with respect to such payment date
shall be the Dollar Equivalent of the Foreign Currency as determined by the Exchange Rate Agent in the manner provided in paragraph (f) below. 

(e) Unless otherwise specified pursuant to Section 301, if the Holder of a Registered Security denominated in any Currency
shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have been made
in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment in Dollars as provided in paragraph
(d) above. 
 (f) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange
Rate Agent and shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion Date. 

(g) For purposes of this Section 312, “Election Date” shall mean the date for any series of Registered
Securities as specified pursuant to clause (13) of Section 301 by which the written election referred to in paragraph (b) above may be made. 

All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency and the Market Exchange
Rate as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Company, the Trustee and all Holders of such Securities denominated or payable in
the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Company and the Trustee of any such decision or determination. 

In the event that the Company determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Company
will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 106 to the affected Holders) specifying the Conversion Date.

 The Trustee shall be fully justified and protected in relying and acting upon information received by it from the Company and the
Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Company or the Exchange Rate Agent. 

SECTION 313. Appointment and Resignation of Successor Exchange Rate Agent. 

(a) Unless otherwise specified pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities,

  
 44 

 
or as so required, at least one Exchange Rate Agent. The Company will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified
pursuant to Section 301 for the purpose of determining the applicable rate of exchange and, if applicable, for the purpose of converting the issued Currency into the applicable payment Currency for the payment of principal (and premium, if any)
and interest, if any, pursuant to Section 312. 
 (b) The Company shall have the right to remove and replace from time
to time the Exchange Rate Agent for any series of Securities. No resignation of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become effective until the acceptance of appointment by the
successor Exchange Rate Agent as evidenced by a written instrument delivered to the Company and the Trustee. 
 (c) If the
Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent for any cause with respect to the Securities of one or more series, the Company, by or pursuant to a
Board Resolution, shall promptly appoint a successor Exchange Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to
the Securities of one or more or all of such series and that, unless otherwise specified pursuant to Section 301, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are
originally issued by the Company on the same date and that are initially denominated and/or payable in the same Currency). 
 ARTICLE FOUR

 SATISFACTION AND DISCHARGE 

SECTION 401. Satisfaction and Discharge of Indenture. 

This Indenture shall upon a Company Request cease to be of further effect with respect to any series of Securities specified in such Company
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 Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series when 

(1) either 
 (A)
all Securities of such series theretofore authenticated and delivered and all coupons, if any, appertaining thereto (other than (i) coupons appertaining to Bearer Securities surrendered for exchange for Registered Securities and maturing after

 and the
Company, 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 in the Currency in which the Securities of such series are payable,
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

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. 
 SECTION 402. Application of Trust Money. 

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, the coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and 

  
 46 

 
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. 
 ARTICLE FIVE 

REMEDIES 
 SECTION 501.
Events of Default. 
 “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), unless such event is specifically deleted or modified in or pursuant to a supplemental indenture, Board Resolution or Officer’s Certificate establishing the terms of such series pursuant to
Section 301 of this Indenture:

related coupon, when such interest or coupon 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

period of 60 days after the receipt by the Company 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 Company
(attention of the General Counsel to the Company via facsimile, with a hard copy then sent, by registered or certified mail) by the Trustee or (ii) to the Company (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 Company 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 Company 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 $75,000,000 and 2% of the Shareholders’ Equity of the Company 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 

  
 47 

 
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 Company 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 Company 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 Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company
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 Company 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 Company 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 Company
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; or 

(7) any other Event of Default provided with respect to Securities of that series. 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

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

  
 48 

 
(or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of that series) 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 Company (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 Company and the Trustee, may rescind and annul such declaration and its consequences
if: 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay in the Currency in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)): 

(A) all overdue interest, if any, on all Outstanding Securities of that series (or of all series, as the case may be) and any
related coupons, 
 (B) all unpaid principal of (and premium, if any) 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

  
 49 

 
have been given to the Trustee by the Company 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. 

The Company covenants that if: 

(1) default is made in the payment of any installment of interest on any Security and any related coupon 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 Company will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such
Securities and coupons, the whole amount then due and payable on such Securities and coupons for principal (and 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 Company 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 Company 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 Company 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. 

SECTION 504. Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or 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 Company 

  
 50 

 
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), or such portion of the principal amount of any series of
Original Issue Discount Securities or Indexed Securities as may be specified in the terms of such series, 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. 
 SECTION 505. Trustee May
Enforce Claims Without Possession of Securities. 
 All rights of action and claims under this Indenture or the Securities or coupons may
be prosecuted and enforced by the Trustee without the possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities and coupons in respect of which such judgment has been recovered. 
 SECTION 506. Application of Money Collected.

 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, if any, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid: 
 First: To the payment of all amounts due the Trustee
under Section 607; 

  
 51 

 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 and coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on
such Securities and coupons for principal (and premium, if any) and interest, if any, respectively; and 
 Third: The
balance, if any, to the Company or to such Person or Persons as the Company instructs in writing. 
 SECTION 507. Limitation on Suits.

 No Holder of any Security of any series or any related coupons 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 Fourteen) and in such Security, of the principal of (and 

  
 52 

 
premium, if any) and (subject to Section 307) interest, if any, on such Security or payment of such coupon on the respective Stated Maturities expressed in such Security or coupon (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. 

SECTION 509. Restoration of Rights and Remedies. 

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 Company, the Trustee and the Holders of Securities and
coupons 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. 

SECTION 510. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511. Delay or Omission Not
Waiver. 
 No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon
any Event of Default 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. 
 SECTION 512. Control by
Holders. 
 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 

  
 53 

 (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. 
 SECTION 513. Waiver of Past Defaults. 

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 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 any related coupon, 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. 

SECTION 514. Waiver of Stay or Extension Laws. 

The Company 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 Company (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. 
 SECTION 515. Undertaking for Costs. 

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.

 ARTICLE SIX 

THE TRUSTEE 
 SECTION

 Within 90 days after the occurrence of any Default hereunder with respect to the Securities of any series,
the Trustee shall transmit in the manner and to the extent provided in TIA Section 313(c), 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 or in the payment of any sinking fund installment with respect to Securities 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 any related coupons, and so advises the Company 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. 

SECTION 602. Certain Duties and Responsibilities of Trustee. 

(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 the 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, 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 the 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 

  
 55 

 
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 TIA 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;

(4) notwithstanding anything contained herein to the contrary, subject to the provisions of TIA Sections 315(a) through 315(d),
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. 
 SECTION 603. Certain Rights of Trustee. 

Subject to the provisions of TIA Sections 315(a) through 315(d): 

(1) the Trustee may, in good faith, rely and shall be protected in acting or refraining from acting upon any resolution, certificate,

Company Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 
 (3) whenever in the

the absence of bad faith on its part, rely upon an Officer’s Certificate; 

  
 56 

 (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 or any related coupons 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 Company, 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; and 
 (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. 
 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, and in any coupons shall be
taken as the statements of the Company, 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 or coupons, 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 the statements made by it in a Statement of
Eligibility on Form T-1 supplied to the Company 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 Company of Securities or
the proceeds thereof. 

  
 57 

 SECTION 605. May Hold Securities. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company or of the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company 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 TIA Section 311(a). 

SECTION 606. Money Held in Trust. 

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 Company. 
 SECTION 607.
Compensation and Reimbursement. 
 The Company agrees: 

(1) to pay to the Trustee from time to time such compensation as the Trustee and the Company 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 Company 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 Company, 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 or any coupons. 
 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 

  
 58 

 
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. 
 SECTION 608. Corporate Trustee Required; Eligibility. 

There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(l) and shall have a

(d) If at any time: 

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

for any cause, with respect to the Securities of one or more series, the Company, 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 Company 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 Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company 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

 SECTION 610. Acceptance of Appointment by Successor. 

(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 Company 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 Company 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 Company, 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 Company
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 Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such 

  
 61 

 
successor Trustee all rights, powers and trusts referred to in paragraph (i) or (ii) 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. 
 SECTION 611. Merger, Conversion, Consolidation or Succession to Business. 

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. 

SECTION 612. Authorization of Authenticating Agent. 

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 Company. 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 Company 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 

  
 62 

 
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 Company. 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 Company. 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 Company 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 Company 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: 

Dated:                      
                     

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

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 Company’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 (B) shall expressly assume, by an indenture supplemental hereto, executed and

(together with, if the Company shall so determine, any other indebtedness of the Company 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; provided
that, for the purpose of providing such equal and ratable security, the principal amount of Original Issue Discount Securities and Indexed Securities shall mean that amount which would at the time of making such effective provision be due and
payable pursuant to Section 502 and the terms of such Original Issue Discount Securities and Indexed Securities upon a declaration of acceleration of the Maturity thereof, and the extent of such equal and ratable security shall be adjusted, to

ARTICLE TEN 
 COVENANTS

 SECTION 1001. Payment of Principal (Premium, if any) and Interest. 

The Company covenants and agrees for the benefit of the Holders of each series of Securities and any related coupons 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, any coupons appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any interest installments due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. 
 SECTION 1002. Maintenance of Office or Agency. 

If the Securities of a series are issuable only as Registered Securities, the Company 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, where Securities of that series that are
convertible or exchangeable may be surrendered for conversion or exchange, as applicable, and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. 

If Securities of a series are issuable as Bearer Securities, the Company will maintain (A) in New York, New York an office or agency
where any Registered Securities of that series may be presented or surrendered for payment, where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable, where notices and demands to or upon the Company in respect of the Securities of that series and this
Indenture may be served 

  
 71 

 
and where Bearer Securities of that series and related coupons may be presented or surrendered for payment in the circumstances described in the following paragraph (and not otherwise), (B)
subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States, an office or agency where Securities of that series and related coupons may be presented and surrendered for
payment; provided, however, that, if the Securities of that series are listed on any securities exchange located outside the United States and such securities exchange shall so require, the Company will maintain a Paying Agent for the
Securities of that series in any required city located outside the United States so long as the Securities of that series are listed on such exchange, and (C) subject to any laws or regulations applicable thereto, in a Place of Payment for that
series located outside the United States an office or agency where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange, where Securities of that
series that are convertible and exchangeable may be surrendered for conversion or exchange, as applicable and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. 

The Company 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 Company 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, except that Bearer Securities of any series and the related coupons may be presented and surrendered for payment at the offices specified in the Security, in London, and the Company hereby appoints the same as its agents to
receive such respective presentations, surrenders, notices and demands. 
 Unless otherwise specified with respect to any Securities
pursuant to Section 301, no payment of principal, premium or interest on Bearer Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an
account maintained with a bank located in the United States; provided, however, that, if the Securities of a series are payable in Dollars, payment of principal of (and premium, if any) and interest, if any, on any Bearer Security
shall be made at the office of the Company’s Paying Agent in New York, New York if (but only if) payment in Dollars of the full amount of such principal, premium or interest, as the case may be, at all offices or agencies outside the United
States maintained for such purpose by the Company in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. 

The Company 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 Company 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 Company 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. Unless otherwise specified with respect to any Securities as contemplated by Section 301 with respect to a series of Securities, the Company 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.

  
 72 

 Unless otherwise specified with respect to any Securities pursuant to Section 301, if and so
long as the Securities of any series (i) are denominated in a Currency other than Dollars or (ii) may be payable in a Currency other than Dollars, or so long as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. 
 SECTION 1003. Money
for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series
of Securities and any related coupons, 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 in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and
312(e)) sufficient to pay the principal of (or premium, if any) or interest, if any, on 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 Company shall have one or more Paying Agents for any series of
Securities and any related coupons, 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 (in the Currency described in the preceding
paragraph) 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 Company will promptly notify the Trustee in writing of its action or failure so to act. 
 The Company 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 Company (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 Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, 

  
 73 

 
such sums to be held by the Trustee upon the same trusts as those upon which sums were held by the Company 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 Company, in trust for the payment of the principal of (or premium, if any) or interest, if any, on any Security of any series, or any coupon appertaining thereto, 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 Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of such Security or coupon shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company 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 Company 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 Company. 
 SECTION 1004. Statement as to Compliance. 

The Company 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 or the Controller of the Company as to his or her knowledge of the Company’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. 
 SECTION 1005. Additional Amounts.

 (a) Unless otherwise provided pursuant to Section 301, all payments made by or on behalf of the Company 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 Company is required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof. If the Company 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 Company 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 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 (such Holder, an “Excluded Holder”) in respect of the beneficial owner thereof: 

  
 74 

 (1) with which the Company does not deal at arm’s length for the purposes of the Income
Tax Act (Canada) at the time of the making of such payment; 
 (2) which is subject to such Canadian Taxes by reason of the Holder 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 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. 
 The Company will also: 

(i) make such withholding or deduction; and 

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

The Company 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 Company. 
 (b) The Company will indemnify
and hold harmless each Holder (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 Company 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 Company will be obligated to pay Additional Amounts with respect to such payment, the Company 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, 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 for purposes of the Canada-U.S. Income Tax Convention (1980), as amended. 

  
 75 

 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. 
 SECTION 1006. Limitation on Liens. 

So long as any Securities are Outstanding and subject to the terms of this Indenture, the Company 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 Company or such Restricted Subsidiaries under any guarantee or
endorsement or other instrument under which the Company 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 Company 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 10% of the Company’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 Company or a Restricted Subsidiary being required to secure the Securities. 
 SECTION 1007. Payment of Taxes. 

The Company 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 Company or any Restricted Subsidiary or upon the income, profits or property of the Company or any Restricted Subsidiary; provided, however, that the Company 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. 

SECTION 1008. Corporate Existence. 

Subject to Article Eight, the Company 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 Company and any Restricted Subsidiary; provided, however, that the Company shall not be required to preserve any such right or franchise if the

  
 76 

 
Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole. 

SECTION 1009. Waiver of Certain Covenants. 

The Company may, with respect to any series of Securities, omit in any particular instance to comply with any term, provision or condition
which affects such series set forth in Section 803 or Sections 1006 through 1008 inclusive or, as specified pursuant to Section 301(17) for Securities of such series, in any covenants of the Company added to Article Ten pursuant to
Section 301(16) or Section 301(17) in connection with Securities of such series, 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 Company 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. 

ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 

SECTION 1101. Applicability of Article. 

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 specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 

SECTION 1102. Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal
amount of 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 1103. 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 Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with
such restriction. 
 SECTION 1103. Selection by Trustee of Securities to Be Redeemed. 

If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 90
days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series: provided, however, that no such partial redemption shall reduce the portion of the principal 

  
 77 

 
amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series established pursuant to Section 301. 

The Trustee shall promptly notify the Company 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. 
 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. 

SECTION 1104. Notice of Redemption. 

Except as otherwise specified as contemplated by Section 301, notice of redemption shall be given in the manner provided for in
Section 106 not less than 30 nor more than 60 days prior to the 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. 

All notices of redemption shall state: 

(1) the Redemption Date. 
 (2) the
Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 1106, 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 1106 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, 

(6) the Place or Places of Payment where such Securities, together in the case of Bearer Securities with all coupons appertaining thereto, if
any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any, 
 (7) that
the redemption is for a sinking fund, if such is the case, 

  
 78 

 (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
surrendered for redemption must be accompanied by all coupons maturing subsequent to the Redemption Date or the amount of any such missing coupon or coupons will be deducted from the Redemption Price unless security or indemnity satisfactory to the
Company, the Trustee and any Paying Agent is furnished, and 
 (9) if Bearer Securities of any series are to be redeemed and any Registered
Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on such Redemption Date pursuant to Section 305 or otherwise, the last date, as determined by
the Company, on which such exchanges may be made. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall
be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 
 SECTION 1105.
Deposit of Redemption Price. 
 At or prior to 10:00 a.m. (New York time) on any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the Currency in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the Redemption Price of, and accrued interest, if any, on all the
Securities which are to be redeemed on that date. 
 SECTION 1106. Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at
the Redemption Price therein specified in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in
Sections 312(b), 312(d) and 312(c)) (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void, Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the
Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of coupons for such interest; and provided further, that installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307. 

  
 79 

 If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be
payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons.

 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 or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 

SECTION 1107. Securities Redeemed in Part. 

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 Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s
attorney duly authorized in writing), and the Company 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. 

SECTION 1108. Tax Redemption. 

Unless otherwise specified pursuant to Section 301, the Company shall have the right to redeem, at any time, the Securities of a series,
in whole but 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 Company (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 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 a date
specified pursuant to Section 301, if any date is so specified, the Company 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 a
date specified pursuant to Section 301, 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 Company, or any change, amendment, 

  
 80 

 
application or interpretation shall be officially proposed, which, in any such case, in the Opinion of Counsel to the Company, will result in the Company 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 Company in its business judgment determines that such obligation cannot be avoided by the use of reasonable
measures available to the Company; provided, however, that (i) no such notice of redemption may be given earlier than 60 or later than 30 days prior to the earliest date on which the Company 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. 

ARTICLE TWELVE 
 SINKING
FUNDS 
 SECTION 1201. Applicability of Article. 

Retirements of Securities of any series pursuant to any sinking fund shall be made in accordance with the terms of such Securities and (except
as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 
 The minimum
amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of
Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. 

SECTION 1202. Satisfaction of Sinking Fund Payments with Securities. 

Subject to Section 1203, in lieu of making all or any part of any mandatory Sinking fund payment with respect to any Securities of a
series in cash, the Company may at its option (1) deliver to the Trustee Outstanding Securities of a series (other than any previously called for redemption) theretofore purchased or otherwise acquired by the Company together in the case of any
Bearer Securities of such series with all unmatured coupons appertaining thereto, and/or (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustee by the Company or for
Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in
each case in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of the same series required to be made pursuant to the terms of such Securities as provided for by the terms of such series;
provided, however, that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. 

  
 81 

 SECTION 1203. Redemption of Securities for Sinking Fund. 

Not less than 60 days prior to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to
the Trustee), the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be
satisfied by payment of cash in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b),
312(d) and 312(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 1202 (which Securities will, if not previously delivered, accompany such certificate) and
whether the Company intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or
payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to deliver such certificate, the sinking fund payment due on the next succeeding sinking fund payment date
for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without the option to deliver or credit Securities as provided in Section 1202
and without the right to make any optional sinking fund payment, if any, with respect to such series. 
 Not more than 60 days before each
such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. 

On or prior to 10:00 a.m. (New York time) on any sinking fund payment date, the Company shall pay to the Trustee or a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) in cash a sum equal to any interest that will accrue to the date fixed for redemption of Securities or portions thereof to be redeemed on such
sinking fund payment date pursuant to this Section 1203. 
 Notwithstanding the foregoing, with respect to a sinking fund for any
series of Securities, if at any time the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not
exceed in the aggregate $100,000, the Trustee, unless requested by the Company, shall not give the next succeeding notice of the redemption of Securities of such series through the operation of the sinking fund. Any such unused balance of moneys
deposited in such sinking fund shall be added to the sinking fund payment for such series to be made in cash on the next succeeding sinking fund payment date or, at the request of the Company, shall be applied at any time or from time to time to the
purchase of Securities of such series, by public or private purchase, in the open market or otherwise, at a purchase price for such Securities (excluding accrued interest and brokerage commissions, for which the Trustee or any Paying Agent will be
reimbursed by the Company) not in excess of the principal amount thereof.

 ARTICLE THIRTEEN 

REPAYMENT AT OPTION OF HOLDERS 

SECTION 1301. Applicability of Article. 

Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms
of such Securities and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 

SECTION 1302. Repayment of Securities. 

Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the
terms of such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that on or
before the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal (or, if
so provided by the terms of the Securities of any series, a percentage of the principal) of and (except if the Repayment Date shall be an Interest Payment Date) accrued interest, if any, on all the Securities or portions thereof, as the case may be,
to be repaid on such date. 
 SECTION 1303. Exercise of Option. 

Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form
on the reverse of such Securities. To be repaid at the option of the Holder, any Security so providing for such repayment, with the “Option to Elect Repayment” form on the reverse of such Security duly completed by the Holder (or by the
Holder’s attorney duly authorized in writing), must be received by the Company at the Place of Payment therefor specified in the terms of such Security (or at such other place or places or which the Company shall from time to time notify the
Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repayment Date. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such
Security surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of
such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of
the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Company. 

  
 83 

 SECTION 1304. When Securities Presented for Repayment Become Due and Payable. 

If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified,
and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, together with all coupons, if any, appertaining thereto
maturing after the Repayment Date, the principal amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided, however, that coupons whose Stated
Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified pursuant to Section 301, only upon
presentation and surrender of such coupons; and provided further, that, in the case of Registered Securities, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment 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 Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as provided in Section 1302 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall
be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons.

 If the principal amount of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount
(together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such
Security. 
 SECTION 1305. Securities Repaid in Part. 

Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security 

  
 84 

 
or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such
Security so surrendered which is not to be repaid. 
  
 ARTICLE
FOURTEEN 
 DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 1401. Company’s Option to Effect Defeasance or Covenant Defeasance. 

Except as otherwise specified as contemplated by Section 301 for Securities of any series, the provisions of this Article Fourteen shall
apply to each series of Securities, and the Company may, at its option, effect defeasance (as defined below) of the Securities of or within a series under Section 1402, or covenant defeasance (as defined below) of or within a series under
Section 1403 in accordance with the terms of such Securities and in accordance with this Article. 
 SECTION 1402. Defeasance and
Discharge. 
 Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within
a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any related coupons on the date the conditions set forth in Section 1404 are satisfied (hereinafter,
“defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any related coupons, which shall thereafter
be deemed to be “Outstanding” only for the purposes of Section 1405 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 any
related coupons and this Indenture insofar as such Securities and any related coupons are concerned (and the Trustee, at the expense of the Company, 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 and any related coupons to receive, solely from the trust fund described in Section 1404 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 and any related coupons when such payments are due, (B) the Company’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
Company’s obligation under Section 607 and (D) this Article Fourteen. Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section 1402 notwithstanding the prior exercise of its option
under Section 1403 with respect to such Securities and any related coupons. 
 SECTION 1403. Covenant Defeasance. 

Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the
Company shall be released from its obligations under Section 803 and Sections 1006 through 1008 inclusive and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding

  
 85 

 
Securities and any related coupons on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter, “covenant defeasance”), and such Securities and
any related coupons 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 and any related coupons, the Company 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 and any related coupons shall be unaffected thereby. 
 SECTION 1404. Conditions to
Defeasance or Covenant Defeasance. 
 The following shall be the conditions to application of either Section 1402 or
Section 1403 to any Outstanding Securities of or within a series and any related coupons: 
 (1) The Company 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 Fourteen 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 and any related coupons, (A) an amount (in such Currency in which such
Securities and any related coupons are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at
Stated Maturity) 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 and any related coupons, 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 Company, 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,
(i) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities and any related coupons on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of
interest, if any, and (ii) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities and any related coupons on the day on which such payments are due and payable in accordance with the terms of this
Indenture and of such Securities and any related coupons; 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 and
any related coupons. Before such a deposit, the Company 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 

  
 86 

 
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 or any related coupons 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 Company is a party or by which it is bound. 

(4) In the case of an election under Section 1402, the Company shall have delivered to the Trustee an Opinion of Counsel
in the United States stating that (x) the Company 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 and any related coupons 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) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in
compliance with any additional or substitute terms, conditions or limitations in connection therewith pursuant to Section 301. 

(6) The Company 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 1402 or the covenant defeasance under Section 1403 (as the case may be) have been complied with. 

(7) In the case of an election under Section 1403, the Company 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. 

(8) Either the Company has delivered to the Trustee an Opinion of Counsel in Canada or a ruling from Canada Revenue Agency to
the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for Canadian federal or provincial income tax or other tax purpose as a result of such defeasance or covenant defeasance and will be subject to
Canadian federal or provincial income tax and other 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 

  
 87 

 
Canadian counsel shall assume that Holders of the Securities include Holders who are not resident in Canada). 

(9) The Company 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). 

(10) The Company 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 1405. 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 (or other property as may be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405,
the “Trustee”) pursuant to Section 1404 in respect of such Outstanding Securities and any related coupons shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any related coupons
and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any related coupons 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. 

Unless otherwise specified with respect to any Security pursuant to Section 301, if, after a deposit referred to in Section 1404(1)
has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 312(b) or the terms of such Security to receive payment in a Currency other than that in which the
deposit pursuant to Section 1404(1) has been, made in respect of such Security, or (b) a Conversion Event occurs as contemplated in Section 312(d) or 312(e) or by the terms of any Security in respect of which the deposit pursuant to
Section 1404(1) has been made, the indebtedness represented by such Security and any related coupons shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as they become due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the
Currency in which such Security becomes payable as a result of such election or Conversion Event based on the applicable Market Exchange Rate for such Currency in effect on the third Business Day prior to each payment date, except, with respect to a
Conversion Event, for such Currency in effect (as nearly as feasible) at the time of the Conversion Event. 
 The Company 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 1404 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 and any related coupons. 

  
 88 

 Anything in this Article Fourteen to the contrary notwithstanding, the Trustee shall deliver or
pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 1404 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. 
 SECTION 1406. Reinstatement. 

If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 1405 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and such Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1402 or 1403, 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 1405; provided, however, that if the
Company makes any payment of principal of (or premium, if any) or interest, if any, on any such Security or any related coupon following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such
Securities and any related coupons to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE FIFTEEN

by any trust company, bank or banker authorized by Section 104 to certify to the holding of Bearer Securities. 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 Company or by Holders of Securities as provided in Section 1502(b), in which case the Company or the 

  
 91 

 
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 Securities of any series duly called pursuant to Section 1502 at which a quorum is present

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

by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank or other depositary, wherever situated, if such certificate shall be deemed by the Trustee to be

  
 13 

 
satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved
by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Corporation may assume that such ownership of any Bearer Security
continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved
in any other manner that the Trustee deems sufficient. 
 (e) If the Corporation shall solicit from the Holders of Registered Securities
any request, demand, authorization, direction, notice, consent, waiver or other Act, the Corporation may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act, but the Corporation shall have no obligation to do so. Notwithstanding Section 316(c) of the Trust Indenture Act, such record date shall be the record date specified in
or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record
date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than eleven months after the record date. 
 (f) Any request, demand, authorization,
direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Corporation in reliance thereon, whether or not notation of such action is made upon such Security. 

SECTION 105. Notices, etc., to Trustee and Corporation. 

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other documents provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the Corporation shall
be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Global Finance Unit, or 

  
 14 

 (2) the Corporation by the Trustee or by any Holder shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Corporation addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at
any other address previously furnished in writing to the Trustee by the Corporation. 
 SECTION 106. Notice to Holders;
Waiver. 
 Where this Indenture provides for notice of any event to Holders of Registered Securities by the Corporation or the Trustee,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer 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 Registered 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 directed by the Corporation shall be deemed to be
sufficient giving of such notice for every purpose hereunder. 
 Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper
in The City of New York and in such other city or cities as may be specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for
the giving of such notice. Any such notice shall be deemed to have been given on the date of the first such publication. 
 In case, by
reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause, it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification
to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders of every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as
provided above, nor any defect in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the sufficiency of any notice to Holders of Registered Securities given as provided herein.

  
 15 

 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. 
 SECTION 107. Effect of Headings and Table of Contents. 

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

SECTION 108. Successors and Assigns. 

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

SECTION 109. Separability Clause. 

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. 
 SECTION 110. Benefits of
Indenture. 
 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. 

SECTION 111. Governing Law. 

This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York. 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. If any provision hereof limits, qualifies or conflicts with a provision of the
Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Indenture, the latter provision shall prevail. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that
may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be. 

  
 16 

 SECTION 112. Legal Holidays. 

In any case where any Interest Payment Date, Redemption Date, sinking fund payment 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 or Redemption Date or sinking fund payment date, or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date,
sinking fund payment date, Stated Maturity or Maturity, as the case may be. 
 SECTION 113. Agent for Service; Submission to
Jurisdiction; Waiver of Immunities. 
 By the execution and delivery of this Indenture, the Corporation (i) acknowledges that it has
irrevocably designated and appointed Alenco Inc., c/o CT Corporation System, 111 8th Avenue, 13th Floor, New York, New York 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 state court in the City of 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 Alenco Inc. 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 Alenco Inc. 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. 
 SECTION 114. Conversion of Currency. 

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

  
 17 

 
series and this Indenture (the “Required Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day 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). 

(ii) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment
referred to in (i) above is given or an order of endorsement 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)(ii) 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 noon rate
for purchases on the relevant date of the Required Currency with the Judgment Currency, as reported by Telerate on screen 3194 (or such other means of reporting the Bank of Canada noon rate as may be agreed upon by each of the parties to this
Indenture) and includes any premiums and costs of exchange payable. 

  
 18 

 SECTION 115. Currency Equivalent. 

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 noon rate as reported by Telerate on screen 3194 (or such other means of reporting the Bank of Canada noon rate as may be agreed upon by each of
the parties to this Indenture) on the date of determination. 
 SECTION 116. No Recourse Against Others. 

A director, officer, employee or shareholder, as such, of the Corporation shall not have any liability for any obligations of the Corporation
under the Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. Such waiver and release shall be
part of the consideration for the issue of the Securities. 
 SECTION 117. Multiple Originals. 

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same
agreement. One signed copy is enough to prove this Indenture. 
 ARTICLE 2 

SECURITY FORMS 

SECTION 201. Forms Generally. 

The Registered Securities, if any, of each series and the Bearer Securities, if any, of each series and related coupons shall be in
substantially the forms as shall be established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith,

Corporate Secretary of the Corporation and delivered to the Trustee at or prior to the delivery of the Corporation Order contemplated by Section 303 for the authentication and delivery of such Securities. Any portion of the text of any Security may
be set forth on the reverse thereof, with an appropriate reference thereto on the face of the Security. 
 Unless otherwise specified as
contemplated by Section 301, Bearer Securities shall have interest coupons attached.

 The Trustee’s certificate of authentication on all Securities shall be in substantially the
form set forth in this Article. 
 The definitive Securities shall be printed, lithographed or engraved on steel-engraved borders or may be

 Subject to Section 611, the Trustee’s certificate of authentication shall be in substantially the following

 SECTION 203. Securities Issuable in Global Form. 

If Securities of or within a series are issuable in global form, as specified as contemplated by Section 301, then, notwithstanding clause (10)
of Section 301, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such series from time to time
endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or
any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Corporation Order to be
delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the applicable Corporation Order. If a Corporation Order pursuant to Section 303 or Section 304 has been, or simultaneously is, delivered, any instructions by the Corporation with
respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 102 and need not be accompanied by an Opinion of Counsel. 

  
 20 

 The provisions of the last sentence of Section 303 shall apply to any Security represented by a
Security in global form if such Security was never issued and sold by the Corporation and the Corporation delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 303. 

Notwithstanding the provisions of Section 307, unless otherwise specified as contemplated by Section 301, payment of principal of (and
premium, if any) and interest, if any, on any Security in permanent global form shall be made to the Person or Persons specified therein. 

Notwithstanding the provisions of Section 309 and except as provided in the preceding paragraph, the Corporation, the Trustee and any agent of
the Corporation or the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a permanent global Security (i) in the case of a permanent global Security in registered form, the Holder of such permanent
global Security in registered form, and (ii) in the case of a permanent global Security in bearer form, Euroclear or Clearstream. 

ARTICLE 3

(14) whether the amount of payments of principal of (or premium, if any) or interest, if any, on the Securities of the

amounts shall be determined;

Securities of the series are to be payable, at the election of the Corporation or a Holder thereof, in a Currency other than that in which such Securities are denominated or stated to be payable, the period or periods within which (including the
Election Date), and the terms and conditions upon which, such election may be made, and the time and manner of determining the exchange rate between the Currency in which such Securities are denominated or stated to be payable and the Currency in
which such Securities are to be so payable, in each case in accordance with, in addition to or in lieu of any of the provisions of Section 312; 

(16) the designation of the initial Exchange Rate Agent, if any; 

(17) the applicability, if any, of Sections 1402 and/or 1403 to the Securities of the series and any provisions in

(18) provisions, if any, granting special rights to the Holders of Securities of the series upon the occurrence of such

 23 

 (26) if the Securities of the series are to be convertible into or
exchangeable for any securities of any Person (including the Corporation), the terms and conditions upon which such Securities will be so convertible or exchangeable; and 

(27) any other terms, conditions, rights and preferences (or limitations on such rights and preferences) relating to the
series which do not apply generally to the Securities (which terms shall not be inconsistent with the requirements of the Trust Indenture Act or the provisions of this Indenture). 

All Securities of any one series and the coupons appertaining to any Bearer Securities of such series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution (subject to Section 303) and set forth in such Officer’s Certificate or in any such indenture supplemental
hereto. Not all Securities of any one series need be issued at the same time, and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series. 

If any of the terms of the series are established by action taken pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of the series. 
 SECTION
302. Denominations. 
 The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by
Section 301. With respect to Securities of any series denominated in Dollars, in the absence of any such provisions, the Registered Securities of such series, other than Registered Securities issued in global form (which may be of any denomination),
shall be issuable in denominations of $1,000 and any integral multiple thereof and the Bearer Securities of such series, other than the Bearer Securities issued in global form (which may be of any denomination), shall be issuable in a denomination
of $5,000. Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture. 

SECTION 303. Execution, Authentication, Delivery and Dating. 

The Securities and any coupons appertaining thereto shall be executed on behalf of the Corporation by its Chairman, its President or a Vice
President together with any one of the Corporate Secretary or Assistant Corporate Secretary and the Treasurer or an Assistant Treasurer of the Corporation, under its corporate seal reproduced thereon. The signature of any of these officers on the
Securities or coupons 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 or coupons. 

Securities or coupons 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 coupons or did not hold such offices at the date of such Securities or
coupons. 

  
 25 

 At any time and from time to time after the execution and delivery of this Indenture, the
Corporation may deliver Securities of any series together with any coupon appertaining thereto, 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; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and provided further that, unless otherwise specified with respect to any series of Securities pursuant to Section 301, a Bearer Security may be delivered in connection with its original issuance only if the
Person entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in Exhibit B-l to this Indenture, dated no earlier than 15 days prior to the earlier of the date on which such Bearer Security is delivered and
the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security,
then, for purposes of this Section and Section 304, the notation of a beneficial owner’s interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner’s interest in such permanent global Security. Except as permitted by Section 306, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons
for interest then matured have been detached and cancelled. If not all the Securities of any series are to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Corporation Order
may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, stated maturity, date of issuance and date from which interest shall accrue.

 At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Securities of any
series, 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 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, an Opinion of Counsel stating: 

(a) that the form or forms of such Securities have been established in conformity with the provisions of this Indenture; 

(b) that the terms of such Securities have been established in conformity with the provisions of this Indenture; 

(c) 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

  
 26 

 
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 (i) applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights, (ii) general equitable principles and (iii)
such other qualifications as such counsel shall conclude do not materially affect the rights of Holders of such Securities and any coupons; 

(d) that all laws and requirements in respect of the execution and delivery by the Corporation of such Securities, any coupons
and of the supplemental indentures, if any, have been complied with and that authentication and delivery of such Securities and the execution and delivery of the supplemental indenture, if any, by the Trustee will not violate the terms of the
Indenture; 
 (e) that the Corporation has the corporate power to issue such Securities and has duly taken all necessary
corporate action with respect to such issuance; and 
 (f) that the issuance of such Securities will not contravene the
articles of incorporation or by-laws of the Corporation. 
 Notwithstanding the provisions of Section 301 and of the preceding two
paragraphs, if not all the Securities of any series are to be issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 301 or the Corporation Order and Opinion of Counsel
otherwise required pursuant to the preceding two paragraphs prior to or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series. 

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. 

Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as
contemplated by Section 301. 
 No Security or coupon 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 310 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 

  
 27 

 
Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 

SECTION 304. Temporary Securities. 

Pending the preparation of definitive Securities of any series, the Corporation may execute, and upon 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, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form. 
 Except in the case of temporary Securities in global form (which shall be exchanged in accordance with
the provisions of the following paragraphs), if temporary Securities of any series are issued, the Corporation will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities
of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Corporation in a Place of Payment for
that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 303. Until so exchanged the temporary Securities of any series shall in all respects be entitled to
the same benefits under this Indenture as definitive Securities of such series. 
 If temporary Securities of any series are issued in
global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London, England office of a depositary or common depositary (the “Common Depositary”), for the benefit of Euroclear and
Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct). 

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary
global Security (the “Exchange Date”), the Corporation shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Corporation. On or
after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary 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 temporary 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 temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global 

  
 28 

 
Security shall be in registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 301, and, if any
combination thereof is so specified, as requested by the beneficial owner thereof; provided, however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global
Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euroclear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or
a subsequent date and signed by Clearstream as to the portion of such temporary global Security held for its account then to be exchanged, each in the form set forth in Exhibit B-2 to this Indenture (or in such other form as may be established
pursuant to Section 301); and provided, further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security only in compliance with the requirements of Section 303. 

Unless otherwise specified in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary
global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and
delivers to Euroclear or Clearstream, as the case may be, a certificate in the form set forth in Exhibit B-1 to this Indenture (or in such other form as may be established pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such temporary
global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like in
the event that such Person does not take delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. 

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301, interest payable on a temporary global Security on an
Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this Indenture (or in such other form as may be established pursuant to Section 301), for credit without further interest thereon on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no earlier than 15 days
prior to the Interest Payment Date occurring prior to such Exchange Date in the form set forth in Exhibit B-1 to this Indenture (or in such other form as may be established pursuant to Section 301). Notwithstanding anything to the contrary herein
contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this Section and of the third paragraph of Section 303 of this Indenture and the interests of the Persons
who are the beneficial owners of the temporary global Security with 

  
 29 

 
respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange Date or the date of certification if such date occurs
after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or interest, if any, owing with respect to a beneficial interest in a
temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear and Clearstream and not paid as herein
provided shall be returned to the Trustee no later than one month prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Corporation in accordance with Section 1003. 

SECTION 305. Registration, Registration of Transfer and Exchange. 

The Corporation shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Registered 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 for each series shall be open to inspection by the applicable security registrar (the “Security Registrar”). The Trustee is hereby initially appointed as
Security Registrar for the purpose of registering Registered Securities and transfers of Registered 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 Registered 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 Registered 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
Registered Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. 
 At the
option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denomination and of a like aggregate principal amount, upon surrender of the Registered Securities to be
exchanged at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Registered Securities, which the Holder making the exchange is
entitled to receive. Unless otherwise specified with respect to any series of Securities as contemplated by Section 301, Bearer Securities may not be issued in exchange for Registered Securities. 

  
 30 

 If (but only if) expressly permitted in or pursuant to the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officer’s Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 301, at the option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all
matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Corporation in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Corporation and the Trustee
if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of
which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of business at such office or agency 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, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be, and 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 the Registered Security issued
in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. 

Whenever any Registered Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is entitled to receive. 
 Notwithstanding the foregoing, except as
otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph and the immediately following 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 tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 301 and 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 Common Depositary or such other 

  
 31 

 
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, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any
combination thereof, as shall be specified by the beneficial owner thereof; 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; and provided, further, that no Bearer Security delivered in exchange for a portion of a permanent global
Security shall be mailed or otherwise delivered to any location in the United States. If a Registered 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 Registered 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 Securities Exchange Act of 1934, as amended, or other
applicable statute or regulation, the Corporation shall appoint a successor depositary with respect to the 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, the Corporation’s election pursuant to Section 301 shall no longer be effective with respect to the 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 Securities of such series in definitive registered form, in authorized
denominations, and in an aggregate principal amount equal to the principal amount of the 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 

  
 32 

 
definitive registered form, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the 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 Registered 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 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, 1107 or 1305 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 1103 or 1203 and ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities,
the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that, to the extent provided with respect to such Bearer Security, such Bearer Security may be exchanged for a
Registered Security of that series and like tenor; provided that such Registered Security shall be immediately surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture, or (iv) to issue,
register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. 

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

  
 33 

 If any mutilated Security or a Security with a mutilated coupon appertaining to it 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 tenor and principal amount and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to the surrendered Security, or, in case any such mutilated Security or coupon has become due and payable, the Corporation in its discretion may, instead of issuing a new Security, with
coupons corresponding to the coupons, if any, appertaining to the surrendered Security, pay such Security. 
 If there shall be delivered to
the Corporation and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them
harmless, then, in the absence of notice to the Corporation or the Trustee that such Security or coupon has been acquired by a bona fide purchaser, the Corporation shall execute and upon Corporation Order the Trustee shall authenticate and deliver,
in lieu of any such destroyed, lost or stolen Security or in exchange for the Security for which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of
like tenor and principal amount 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, with coupons corresponding
to the coupons, if any, appertaining to such mutilated, destroyed, lost or stolen Security or to the Security to which such mutilated, destroyed, lost or stolen coupon appertains, pay such Security or coupon; provided, however, that payment
of principal of (and premium, if any) and interest, if any, on Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an office or agency located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. 

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 with its coupons, if any, issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or stolen coupon appertains, shall constitute an original contractual obligation of the Corporation, whether or not the mutilated, destroyed, lost or stolen Security and
its coupons, if any, or the mutilated, destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, 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 

  
 34 

 
the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons. 

SECTION 307. Payment of Principal and Interest; Interest Rights Preserved; Optional Interest Reset. 

(a) Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest, if any, on any Registered
Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name 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, however, that each installment of the principal of (and premium, if any, on) and interest, if
any, on any Registered Security may at the Corporation’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 309, to the address of such Person as it
appears on the Security Register or (ii) wire transfer to an account located in the United States maintained by the payee (with wire transfer instructions provided to the Trustee not less than 15 days prior to payment of interest by wire transfer);
provided further, that principal paid in relation to any Security redeemed at the option of the Corporation pursuant to Article Eleven, 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(a). 
 Unless otherwise provided as contemplated by Section 301 with
respect to the Securities of any series, payment of interest, if any, may be made, in the case of a Bearer Security, by transfer to an account located outside the United States maintained by the payee. 

Unless otherwise provided as contemplated by Section 301, every permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to each of Euroclear and Clearstream with respect to that portion of such permanent global Security held for its account by the Common Depositary, for the purpose of permitting each of Euroclear and Clearstream to
credit the interest, if any, received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof. 

Any interest on any Registered 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 by virtue of having been such Holder, 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 in
clause (1) or (2) below: 
 (1) The Corporation may elect to make payment of any Defaulted Interest to the Persons in whose
names the Registered 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 

  
 35 

 
proposed to be paid on each Registered 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 in the
Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) 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 Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 

(2) The Corporation may make payment of any Defaulted Interest on the Registered Securities of any series in any other lawful
manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Corporation to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 (b) The provisions of this Section
307(b) may be made applicable to any series of Securities pursuant to Section 301 (with such modifications, additions or substitutions as may be specified pursuant to such Section 301). The interest rate (or the spread or spread multiplier used to
calculate such interest rate, if applicable) on any Security of such series may be reset by the Corporation on the date or dates specified on the face of such Security (each an “Optional Reset Date”). The Corporation may exercise such
option with respect to such Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date for such Security, which notice shall specify the information to be included in the Reset Notice (as
defined). Not later than 40 days prior to each Optional Reset Date, the Trustee shall transmit, in the manner provided for in Section 106, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Corporation
has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions,
if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of such Security (each such period a “Subsequent Interest
Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. 

  
 36 

 Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the
Corporation may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or a spread or spread multiplier used
to calculate such interest rate, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustee to transmit, in the
manner provided for in Section 106, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest
rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have
validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable). 

The Holder of any such Security will have the option to elect repayment by the Corporation of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment
at the option of Holders except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment
pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset 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. 

SECTION 308. Optional Extension of Stated Maturity. 

The provisions of this Section 308 may be made applicable to any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301). The Stated Maturity of any Security of such series may be extended at the option of the Corporation for the period or periods specified on the face of such Security (each
an “Extension Period”) up to but not beyond the date set forth on the face of such Security. The Corporation may exercise such option with respect to any Security by notifying the Trustee of such exercise at least 50 but not more than 60
days prior to the Stated Maturity of such Security in effect prior to the exercise of such option (the “Original Stated Maturity”). If the Corporation exercises such option, the Trustee shall transmit, in the manner provided for in Section
106, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “Extension Notice”) indicating (i) the election of the Corporation to extend the Stated Maturity, (ii) the new Stated Maturity,
(iii) the interest rate, if any, applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice, the Stated Maturity of such Security shall
be extended automatically and, except as modified by the 

  
 37 

 
Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Extension Notice. 

Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Corporation may, at its
option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 106, notice of such higher interest rate to
the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 

If the Corporation extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the
Corporation on the Original Stated Maturity at a price equal to the principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Corporation has extended the Maturity thereof,
the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original
Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment until the close of business on the tenth day
before the Original Stated Maturity. 
 SECTION 309. Persons Deemed Owners. 

Prior to due presentment of a Registered Security for registration of transfer, the Corporation, the Trustee and any agent of any of the
foregoing may treat the Person in whose name such Registered 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 Registered Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Corporation, the Trustee or any agent of any of the foregoing shall be affected by notice to the contrary. 

Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Corporation, the Trustee and any agent of the
Corporation or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupons 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. 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. 

  
 38 

 Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent
the Corporation, the Trustee, or any agent of any of the foregoing 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. 

SECTION 310. Cancellation. 

All Securities surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit
against any current or future sinking fund payment 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, then, unless provided otherwise in a supplemental indenture relating to a series of Securities, 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 certification of their disposal delivered to the Corporation unless by Corporation Order the Corporation shall direct that cancelled
Securities be returned to it. 
 SECTION 311. Computation of Interest. 

Except as otherwise specified as contemplated by Section 301 with respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. For the purposes of disclosure under the Interest Act (Canada), the yearly rate of interest to which interest calculated under a Security for any period in any calendar
year (the “calculation period”) is equivalent, is the rate payable under a Security in respect of the calculation period multiplied by a fraction the numerator of which is the actual number of days in such calendar year and the denominator
of which is the actual number of days in the calculation period. 
 SECTION 312. Currency and Manner of Payments in Respect of
Securities. 
 (a) With respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or
the Holders of which have not made the election provided for in paragraph (b) below, and with respect to Bearer Securities of any series except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and interest, if
any, on any Registered or Bearer Security of such series will be made in the Currency in which such Registered or Bearer Security, as the case may be, is payable. The provisions of this 

  
 39 

 
Section 312 may be modified or superseded with respect to any Securities pursuant to Section 301. 

(b) It may be provided pursuant to Section 301 with respect to Registered Securities of any series that Holders shall have the option,
subject to paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered Securities in any of the Currencies which may be designated for such election by delivering to the Trustee a
written election with signature guarantees and in the applicable form established pursuant to Section 301, not later than the close of business on the Election Date immediately preceding the applicable payment date. If a Holder so elects to receive
such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustee (but any such change must be made not later
than the close of business on the Election Date immediately preceding the next payment date to be effective for the payment to be made on such payment date and no such change of election may be made with respect to payments to be made on any
Registered Security of such series with respect to which an Event of Default has occurred or with respect to which the Corporation has deposited funds pursuant to Article Four or Fourteen or with respect to which a notice of redemption has been
given by the Corporation or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Registered Security who shall not have delivered any such election to the Trustee not later than the close of
business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant Currency as provided in Section 312(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable after the Election
Date of the aggregate principal amount of Registered Securities for which Holders have made such written election. 
 (c) Unless
otherwise specified pursuant to Section 301, if the election referred to in paragraph (b) above has been provided for pursuant to Section 301, then, unless otherwise specified pursuant to Section 301, not later than the fourth Business Day after the
Election Date for each payment date for Registered Securities of any series, the Exchange Rate Agent will deliver to the Corporation a written notice specifying, in the Currency in which Registered Securities of such series are payable, the
respective aggregate amounts of principal of (and premium, if any) and interest, if any, on the Registered Securities to be paid on such payment date, specifying the amounts in such Currency so payable in respect of the Registered Securities as to
which the Holders of Registered Securities of such series shall have elected to be paid in another Currency as provided in paragraph (b) above. If the election referred to in paragraph (b) above has been provided for pursuant to Section 301 and if
at least one Holder has made such election, then, unless otherwise specified pursuant to Section 301, on the second Business Day preceding such payment date the Corporation will deliver to the Trustee for such series of Registered Securities an
Exchange Rate Officer’s Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Unless otherwise specified pursuant to Section 301, the Dollar or Foreign Currency amount receivable by Holders of
Registered Securities who have elected payment in a Currency as provided in paragraph (b) above shall be determined by the Corporation on the basis of the applicable Market Exchange Rate in effect on the third Business Day (the “Valuation
Date”) immediately preceding each payment date, and such determination shall be conclusive and binding for all purposes, absent manifest error. 

  
 40 

 (d) If a Conversion Event occurs with respect to a Foreign Currency in which any of the
Securities are denominated or payable other than pursuant to an election provided for pursuant to paragraph (b) above, then with respect to each date for the payment of principal of (and premium, if any) and interest, if any, on the applicable
Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the Dollar shall be the Currency of payment for use on each such payment date. Unless
otherwise specified pursuant to Section 301, the Dollar amount to be paid by the Corporation to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign
Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in
paragraph (f) or (g) below. 
 (e) Unless otherwise specified pursuant to Section 301, if the Holder of a Registered Security
denominated in any Currency shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment
would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment in Dollars as provided in
paragraph (d) above. 
 (f) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange Rate Agent and
shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion Date. 

(g) The “Dollar Equivalent of the Currency Unit” shall be determined by the Exchange Rate Agent and subject to the provisions of
paragraph (h) below shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency into Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date with respect to each payment. 

(h) For purposes of this Section 312 the following terms shall have the following meanings: 

A “Component Currency” shall mean any Currency which, on the Conversion Date, was a component currency of the
relevant currency unit. 
 A “Specified Amount” of a Component Currency shall mean the number of units of such
Component Currency or fractions thereof which were represented in the relevant currency unit, on the Conversion Date. If after the Conversion Date the official unit of any Component Currency is altered by way of combination or subdivision, the
Specified Amount of such Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such
Component Currencies shall be replaced by an amount in such single Currency equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed 

  
 41 

 
in such single Currency, and such amount shall thereafter be a Specified Amount and such single Currency shall thereafter be a Component Currency. If after the Conversion Date any Component
Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced by amounts of such two or more currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date
of such replacement equal to the Dollar Equivalent value of the Specified Amount of such former Component Currency at the Market Exchange Rate immediately before such division and such amounts shall thereafter be Specified Amounts and such
currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, a Conversion Event (other than any event referred to above in this definition of “Specified Amount”) occurs with respect to
any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars
at the Market Exchange Rate in effect on the Conversion Date of such Component Currency. 
 “Election Date” shall
mean the date for any series of Registered Securities as specified pursuant to clause (15) of Section 301 by which the written election referred to in paragraph (b) above may be made. 

All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of
the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the
Corporation, the Trustee and all Holders of such Securities denominated or payable in the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Corporation and the Trustee of any such decision or determination. 

In the event that the Corporation determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the
Corporation will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 106 to the affected Holders) specifying the Conversion
Date. In the event the Corporation so determines that a Conversion Event has occurred with respect to any currency unit in which Securities are denominated or payable, the Corporation will immediately give written notice thereof to the Trustee and
to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 106 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion
Date. In the event the Corporation determines in good faith that any subsequent change in any Component Currency as set forth in the definition of Specified Amount above has occurred, the Corporation will similarly give written notice to the Trustee
and the Exchange Rate Agent. 
 The Trustee shall be fully justified and protected in relying and acting upon information received by it
from the Corporation and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Corporation or the Exchange Rate Agent. 

  
 42 

 SECTION 313. Appointment and Resignation of Successor Exchange Rate Agent. 

(a) Unless otherwise specified pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a Foreign
Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Corporation will maintain with respect to each such series of Securities, or as so required, at least one
Exchange Rate Agent. The Corporation will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 301 for the purpose of determining the applicable rate of
exchange and, if applicable, for the purpose of converting the issued Currency into the applicable payment Currency for the payment of principal (and premium, if any) and interest, if any, pursuant to Section 312. 

(b) The Corporation shall have the right to remove and replace from time to time the Exchange Rate Agent for any series of Securities. No
resignation or removal of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become effective until the acceptance of appointment by the successor Exchange Rate Agent as evidenced by a
written instrument delivered to the Corporation and the Trustee. 
 (c) If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent for any cause with respect to the Securities of one or more series, the Corporation, by or pursuant to a Board Resolution, shall promptly appoint a successor
Exchange Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series
and that, unless otherwise specified pursuant to Section 301, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are originally issued by the Corporation on the same date and that are
initially denominated and/or payable in the same Currency). 
 ARTICLE 4 

SATISFACTION AND DISCHARGE 

SECTION 401. Satisfaction and Discharge of Indenture. 

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 

(1) either

(other than (i) coupons appertaining to Bearer Securities surrendered for exchange for Registered Securities and maturing after such exchange, whose surrender is not required or has been waived as provided in Section 305, (ii) Securities and coupons
of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, (iii) coupons appertaining to Securities called for redemption and maturing after the relevant Redemption Date, whose surrender

thereafter repaid to the Corporation, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 

(B) all Securities of such series and, in the case of (i) or (ii) below, not theretofore delivered to the Trustee for
cancellation 
 (i) have become due and payable, or 

(ii) will become due and payable at their Stated Maturity within one year, 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 in the Currency in which the Securities of such series are payable,
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 with respect to the Outstanding Securities 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 606, the
obligations of the Trustee to any Authenticating Agent under Section 611 and, if money shall have been deposited with the 

  
 44 

 
Trustee pursuant to subclause (B) of clause (1) of this Section and the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. 

SECTION 402. Application of Trust Money. 

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.

 ARTICLE 5 

REMEDIES 
 SECTION 501.
Events of Default. 
 “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), unless such event is specifically deleted or modified in or pursuant to a supplemental indenture, Board Resolution or Officer’s Certificate establishing the terms of such series pursuant to this Indenture:

 (1) default in the payment of the principal of (or premium, if any, on) any Security of that series at its Maturity;
or 
 (2) default in the payment of any interest or Additional Amounts on any Security of that series, or any related
coupon, when such interest, coupon or Additional Amounts become due and payable, and continuance of such default for a period of 30 days; or 

(3) default in the deposit of any sinking fund payment, when such payment becomes due by the terms of the Securities of
that series and Article Twelve; or 
 (4) default in the performance, or breach, of any covenant or warranty of the
Corporation in this Indenture in respect of the 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 there has been given to the Corporation by the Trustee to the attention of the General Counsel to the Corporation via facsimile, with a hard copy then sent, by registered or certified mail, or to
the Corporation and the Trustee by the Holders of at least 25% in principal amount of all Outstanding Securities of any 

  
 45 

 
series affected thereby, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 

(5) if an event of default (as defined in any indenture or instrument under which the Corporation or a Subsidiary has, at
the time of the Indenture or shall thereafter have, outstanding any indebtedness for borrowed money) shall happen and be continuing and such indebtedness shall have been accelerated so that an amount in excess of US$75,000,000 shall be or become due
and payable 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 under such indenture or
instrument shall not be remedied or cured, whether by payment or otherwise, or waived by the holders of such 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 the Indenture until 30 days after written notice thereof shall
have been given to the Corporation by the Trustee, or to the Corporation and the Trustee by the holders of not less than 25% in aggregate principal amount of Outstanding Securities, or (b) if the accelerated indebtedness shall occur 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 non-recourse to the
borrower, it shall not be considered an Event of Default for purposes of this Indenture or (ii) if such accelerated indebtedness is recourse to the borrower, any requirement in connection with such 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 shall be applicable together with an additional seven days before being considered an Event of Default for purposes of this Indenture; or

 (6) 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 

(7) 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 

  
 46 

 
of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due; or 

(8) any other Event of Default provided with respect to Securities of that series. 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default described in clause (1), (2) or (3) of 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 principal amount of the Outstanding Securities of that series may, subject to subordination provisions, if any, declare the principal amount (or, if
the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of such affected series) of all of the Securities of that series and all interest
thereon 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. If an Event of Default described in clause (4) or (8) of Section 501 occurs and is continuing with respect to the Securities of one or more series, then in every such case the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Securities of all series affected thereby (as one class) may declare the principal amount (or, if any such Securities are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be
specified in the terms of such affected series) of all of the Outstanding Securities of such affected series and all interest thereon to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustee if given by the
Holders) and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable. If an Event of Default described in clause (5), (6) or (7) of Section 501 occurs and is continuing, then in every
such case the Trustee or the Holders of not less than 25% in principal amount of all the Securities then Outstanding (as a class) may declare the principal amount (or, if any such Securities are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Outstanding Securities and all interest thereon to be due and payable immediately, by a notice in writing to the Corporation (and to the
Trustee if given by the Holders), and upon any such declaration such principal amount (or specified portion thereof) shall become immediately due and payable. 

At any time after a declaration of acceleration with respect to Securities of any series (or of all series, as the case may be) has been made
and 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 in the Currency in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)), 

  
 47 

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

The Corporation covenants that if: 

(1) default is made in the payment of any installment of interest on any Security and any related coupon 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 and coupons, the whole amount then due and payable on such Securities and coupons for principal (and premium, if any) and interest, if any, and, to the extent lawful, 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 amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the 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 

  
 48 

 
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. 

SECTION 504. Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Corporation or any other obligor upon the Securities or the property of the Corporation or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then
be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Corporation for the payment of overdue principal, premium, if any, or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise, 
 (i) to file and prove a claim for the whole amount of
principal (and premium, if any), or such portion of the principal amount of any series of Original Issue Discount Securities or Indexed Securities as may be specified in the terms of such series, 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 
 (ii) 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 606. 

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. 

  
 49 

 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name 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. 
 SECTION 506. Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal (or premium, if any) or interest, if any, upon presentation of the applicable Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid: 
 First: To the payment of all amounts due the Trustee under Section 606;

 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 and coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities and coupons for
principal (and premium, if any) and interest, if any, respectively; and 
 Third: The balance, if any, to the Person
or Persons entitled thereto. 
 SECTION 507. Limitation on Suits. 

No Holder of any Security of any series or any related coupons 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 principal amount of the Outstanding Securities of all
series affected by such Event of Default (determined as provided in Section 502 and as one class), 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; 

  
 50 

 (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 all series affected by such Event of Default (determined as provided in Section 502 and as one
class); 
 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 Outstanding Securities of any such affected series, 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 Outstanding Securities of all such affected series. 

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium 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 Fourteen) 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. 

SECTION 509. Restoration of Rights and Remedies. 

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 and
coupons 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. 

SECTION 510. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent
permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 511. Delay or Omission Not
Waiver. 

  
 51 

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

SECTION 512. Control by Holders. 

The Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected by an Event of Default
(determined as provided in Section 502 and as one class) 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, with
respect to the Outstanding Securities of such affected series, provided 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 Outstanding Securities of such affected series not consenting. 

SECTION 513. Waiver of Past Defaults. 

Subject to Section 502, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series with respect to
which a Default shall have occurred and be continuing (as one class) may on behalf of the Holders of all the Outstanding Securities of such affected series waive any past Default, 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 any related
coupon or the payment of Additional Amounts, 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 affected series. 
 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. 
 SECTION 514. Waiver of Stay or Extension Laws. 

  
 52 

 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. 
 ARTICLE 6 

THE TRUSTEE 
 SECTION
601. Notice of Defaults. 
 Within 90 days after the occurrence of any Default hereunder with respect to the Securities of any series,
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 or in the payment of any sinking fund installment with respect to Securities 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 provided further that in the case of any Default of the character specified in Section 501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 60 days after the occurrence thereof. 
 SECTION 602. Certain Rights of Trustee. 

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

(1) the Trustee may rely and shall be protected in acting or refraining from acting upon any statutory declaration, 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; 

  
 53 

 (4) 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; and 
 (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. 
 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. 
 SECTION 603. 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, and in any coupons 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 or the coupons, 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 the 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. 

  
 54 

 SECTION 604. May Hold Securities. 

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 coupons 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. 
 SECTION 605. Money Held in Trust. 

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. 
 SECTION 606.
Compensation and Reimbursement. 
 The Corporation agrees: 

(1) to pay to the Trustee from time to time reasonable compensation 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 willful misconduct, negligence or bad faith; and 
 (3) to indemnify the
Trustee for, and to hold it harmless against, any loss, liability or expense incurred without willful misconduct, negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts
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 or any coupons. 
 When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 501(6) or (7), the expenses (including reasonable charges and 

  
 55 

 
expense of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable bankruptcy, insolvency or other similar law. 

“Trustee” for purposes of this Section 606 shall include any predecessor Trustee but the willful misconduct, negligence or bad faith
of any Trustee shall not affect the rights of any other Trustee under this Section 606. 
 The provisions of this Section shall survive the
termination of this Indenture. 
 SECTION 607. Corporate Trustee Required; Eligibility. 

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 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. 

SECTION 608. Resignation and Removal; Appointment of Successor. 

(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 609. 
 (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 609 shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may 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 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. 
 (d) If at any time: 

(1) 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 
 (2)
the Trustee shall cease to be eligible under Section 607 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 

  
 56 

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

then, in any such case, (i) the Corporation, by or pursuant to authority granted by a Board Resolution, 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 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 removal of the Trustee with respect to all Securities of such series and the appointment of a successor Trustee or Trustees. 

(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 or pursuant to authority granted 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. 

SECTION 609. Acceptance of Appointment by Successor. 

(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 

  
 57 

 
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, unless contemplated otherwise by such supplemental indenture, 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. 
 SECTION 610. Merger, Conversion, Consolidation or Succession to Business. 

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 

  
 58 

 
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. 

SECTION 611. Appointment of Authenticating Agent. 

At any time when any of the Securities remain Outstanding, the Trustee may appoint 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 appointment 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 

  
 59 

 
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 appoint a successor Authenticating Agent which shall be acceptable to the Corporation and
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. Any successor Authenticating Agent upon acceptance of its
appointment 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 appointed unless eligible
under the provisions of this Section. 
 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation
for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 606. 

If an appointment 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: 

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

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

SECTION 702. Preservation of List of Names and Addresses of Holders. 

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders

CONVEYANCE, TRANSFER OR LEASE 

SECTION 801. Corporation May Amalgamate or Consolidate, etc., Only on Certain Terms. 

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

(1) in a transaction in which the Corporation does not survive or continue or in which the Corporation sells, assigns, conveys,
transfers or leases or otherwise disposes of all or substantially all of its properties and assets, the entity formed by such amalgamation or consolidation or into which the Corporation is merged or with which it enters into such arrangement or the
Person which acquires by conveyance or transfer or otherwise, or which leases, all or substantially all the properties and assets of the Corporation, (A) shall be a corporation, partnership or trust organized and validly existing (i) 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, 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 obligations under the Securities and this Indenture; 

(2) immediately before and after giving effect to such transaction, no Default or Event of Default shall have occurred and be
continuing; 
 (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 consolidation, amalgamation, statutory arrangement, 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. 

  
 63 

 For greater certainty, the Corporation shall be considered to be the continuing corporation in
the event of an amalgamation by the Corporation with any Wholly-Owned Subsidiary of the Corporation pursuant to Section 178 (or any successor thereto) of the Business Corporations Act (Alberta). 

SECTION 802. Successor Person Substituted. 

Upon any consolidation or amalgamation by the Corporation, statutory arrangement with or merger by the Corporation into any other corporation
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, the successor Person formed by such consolidation or amalgamation or statutory arrangement
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. 
 SECTION 803. Assignment of Rights. 

Subject to Section 801, the Corporation will have the right at all times to assign any of its rights or obligations under this Indenture to a
Wholly-Owned Subsidiary of the Corporation; provided, however, that in the event of any such assignment, the Corporation will remain fully and unconditionally liable for all of its obligations pursuant to the Securities and the Indenture by
execution of an indenture supplemental hereto, in form satisfactory to the Trustee. Subject to the foregoing, this Indenture will be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. 

SECTION 804. Securities to Be Secured in Certain Events. 

If, upon any consolidation, amalgamation or statutory arrangement of the Corporation with or merger of the Corporation into any other Person,
or upon any conveyance, transfer or lease of all or substantially all of the properties and assets of the Corporation to any other Person, any of the property and assets of the Corporation would thereupon become subject to any Lien, then unless such
Lien could be created pursuant to Section 1009 without equally and ratably securing the Securities, the Corporation prior to or simultaneously with such consolidation, amalgamation, statutory arrangement, merger, conveyance, transfer or lease, will
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, conveyance, transfer or lease is to become secured by such Lien, or will cause such Securities to be so secured; provided that, for the purpose of providing such
equal and ratable security, the principal amount of Original Issue Discount Securities and Indexed Securities shall mean that amount which would at the time of making 

  
 64 

 
such effective provision be due and payable pursuant to Section 502 and the terms of such Original Issue Discount Securities and Indexed Securities upon a declaration of acceleration of the
Maturity thereof, and the extent of such equal and ratable security shall be adjusted, to the extent permitted by law, as and when said amount changes over time pursuant to the terms of such Original Issue Discount Securities and Indexed Securities.

 ARTICLE 9 

SUPPLEMENTAL INDENTURES 

SECTION 901. Supplemental Indentures Without Consent of Holders. 

Without the consent of any Holders, the Corporation, when authorized by or pursuant to a Board Resolution, and the Trustee, at any time and

(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 804 or 1009 or otherwise; or 

(6) to establish the form or terms of Securities of any series as permitted by Sections 201 and 301; or 

(7) 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 609(b); or 

  
 65 

 (8) to close this Indenture with respect to the authentication and delivery
of additional series of Securities, to cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under
this Indenture; provided such action shall not adversely affect the interests of the Holders of Securities of any series in any material respect; or 

(9) 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, 1402 and 1403; 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. 
 SECTION 902. Supplemental Indentures with Consent of Holders. 

With the consent of the Holders of not less than a majority in principal amount of all Outstanding Securities of any 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 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) subject to Section 308, 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 reduce the amount of the principal of an Original Issue Discount Security of such series that would be
due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable in bankruptcy pursuant to Section 504, or adversely affect any right of repayment at the option of any Holder of any
Security of such series, 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 or repayment at the option of the Holder, on or after the Redemption Date or Repayment Date, as the case may be), or adversely affect any right to convert or exchange any Security as
may be provided pursuant to Section 301 herein, or 
 (2) reduce the percentage in principal amount of the Outstanding
Securities of such series required for any modification or amendment of this Indenture 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 1504 for quorum or voting with respect to Securities of such series, or 

  
 66 

 (3) modify any of the provisions of this Section, Section 513 or Section 1010,
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. 

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. 
 SECTION 903. Execution of Supplemental
Indentures. 
 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, 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. 

SECTION 904. Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such

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

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. 

  
 67 

 SECTION 907. Notice of Supplemental Indentures. 

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. 

ARTICLE 10 
 COVENANTS

 SECTION 1001. Payment of Principal, Premium, if any, and Interest. 

The Corporation covenants and agrees for the benefit of the Holders of each series of Securities and any related coupons 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, any coupons appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any interest installments due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. 
 SECTION 1002. Maintenance of Office or Agency. 

If the Securities of a series are issuable only as Registered Securities, the Corporation will maintain or cause to be maintained 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, where Securities of
that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable and where notices and demands to or upon the Corporation in respect of the Securities of that series and this Indenture may be served. 

If Securities of a series are issuable as Bearer Securities, the Corporation will maintain an office or agency outside the United States where
any Bearer Securities of that series and related coupons may be presented or surrendered for payment, where any Bearer Securities of that series may be surrendered for registration of transfer, where Bearer Securities of that series may be
surrendered for exchange, where Bearer Securities of that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable, where notices and demands to or upon the Corporation in respect of the Bearer
Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered for payment; provided, however, that, if the Bearer Securities of that series are listed
on any stock exchange located outside the United States and such stock exchange shall so require, the Corporation will maintain a Paying Agent for the Securities of that series in any required city located outside the United States so long as the
Bearer Securities of that series are listed on such exchange. 

  
 68 

 The Corporation will give prompt written notice to the Trustee of the location, and any change in
the location, of any 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 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, except that Bearer Securities of any series and the related coupons may be presented and surrendered for payment at the offices specified in the Security, and the Corporation hereby
appoints the same as its agent to receive such respective presentations, surrenders, notices and demands. 
 Unless otherwise specified with
respect to any Securities pursuant to Section 301, no payment of principal, premium or interest on Bearer Securities shall be made at any office or agency of the Corporation in the United States or by check mailed to any address in the United States
or by transfer to an account maintained with a bank located in the United States; provided, however, that, if the Securities of a series are payable in Dollars, payment of principal of (and premium, if any) and interest, if any, on any
Bearer Security shall be made at the office of the Corporation’s Paying Agent in The City of New York, if (but only if) payment in Dollars of the full amount of such principal, premium or interest, as the case may be, at all offices or agencies
outside the United States maintained for such purposes by the Corporation in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. 

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. Unless otherwise specified with respect to any Securities as contemplated by Section 301 with respect to a series of Securities, the Corporation hereby designates as a Place of Payment for each series of
Securities the office or agency of the Corporation in Calgary, Alberta, Canada, 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. 
 Unless otherwise specified with respect to any Securities pursuant to Section 301, if and so long as the Securities of any
series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of the Indenture, then the Corporation will maintain with respect to each such series of
Securities, or as so required, at least one Exchange Rate Agent. 
 SECTION 1003. Money for Securities Payments to Be Held in Trust.

 If the Corporation shall at any time act as its own Paying Agent with respect to any series of Securities and any related coupons, 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 in the Currency or 

  
 69 

 Currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section
301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal of (or premium, if any) or interest, if any, on 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 of its action or failure so to act. 

Whenever the Corporation shall have one or more Paying Agents for any series of Securities and any related coupons, 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 (in the Currency or Currencies described in the preceding paragraph) 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 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 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, or any coupon appertaining thereto, and remaining unclaimed for two years after such principal, premium or interest has become due
and payable shall be paid to the Corporation, or (if then held by the 

  
 70 

 Corporation) shall be discharged from such trust; and the Holder of such Security or coupon 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, shall at the written direction and 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. 

SECTION 1004. Statement as to Compliance. 

The Corporation will deliver to the Trustee, within 140 days after the end of each fiscal year, a certificate from the principal executive
officer, principal financial officer or principal accounting officer as to his or her knowledge of whether the Corporation is in compliance with all conditions and covenants under this Indenture and, if not in such compliance, specifying all such
known defaults. 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. 

SECTION 1005. Additional Amounts. 

If specified pursuant to Section 301, all payments made by 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 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 “Taxes”), unless the Corporation is required to withhold or deduct 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 Taxes from any payment made under or with respect to the Securities, the Corporation will pay such additional amounts (“Additional Amounts”) as may be
necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction will not be less than the amount the Holder would have received if such Taxes had not been withheld or deducted;
provided that no Additional Amounts will be payable: 
 (1) to any Person in respect of whom such taxes are
required to be withheld or deducted as a result of such Person not dealing at arm’s length with the Corporation (within the meaning of the Income Tax Act (Canada)); 

(2) to any Person by reason of such Person being connected with Canada (otherwise than merely by holding or ownership of
any series of Securities or receiving any payments or exercising any rights thereunder), including without limitation a non-resident insurer who carries on an insurance business in Canada and in a country other than Canada; 

  
 71 

 (3) for or on account of any tax, assessment or other governmental charge which
would not have been so imposed but for the presentation by the Holder of such Security or coupon for payment on a date more than 10 days after the date on which such payment became due and payable or the date on which payment thereof is duly
provided for, whichever occurs later; 
 (4) for or on account of any estate, inheritance, gift, sales, transfer, personal
property tax or any similar tax, assessment or other governmental charge; 
 (5) for or on account of any tax, assessment or other
governmental charge required to be withheld by any paying agent from any payment to a Person in respect of any Security, if such payment can be made to such person without such withholding by at least one other paying agent the identity of which is
provided to such Person; 
 (6) for or on account of any tax, assessment or other governmental charge which is payable otherwise than by
withholding from a payment in respect of such Security; or 
 (7) for any combination of items (1), (2), (3), (4), (5) and (6); 

nor will Additional Amounts be paid with respect to any payment on a Security to a Holder who is a fiduciary or partnership or other than the sole beneficial
owner of such payment to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Security. 

At least 10 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, 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. Whenever in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), Redemption Price,
interest or any other amount payable under or with respect to any Security such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such context, Additional Amounts are,
were or would be payable in respect thereof pursuant to the provisions of this Section and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those
provisions hereof where such express mention is not made (if applicable). 
 The obligations of the Corporation under this Section 1005
shall survive the termination of the Indenture. 

  
 72 

 SECTION 1006. Payment of Taxes and Other Claims. 

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 upon the income, profits or property of the Corporation; provided, however, that the Corporation shall not be required to pay or discharge or cause to be
paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 

SECTION 1007. Maintenance of Properties. 

The Corporation will cause all its properties to be maintained and kept in good condition, repair and working order and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Corporation may be necessary so that the business carried on in connection therewith may
be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent or restrict the sale, abandonment or other disposition of any of such properties if such action is, in the judgment of the
Corporation desirable in the conduct of the business of the Corporation. 
 SECTION 1008. Corporate Existence. 

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; 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, as the case may be. 

SECTION 1009. Limitation on Liens. 

So long as any Securities are Outstanding, the Corporation will not, and will not permit any Subsidiary of the Corporation to, create, incur or
assume any Lien securing any indebtedness for borrowed money or interest thereon (or any liability of the Corporation or such Subsidiary under any guarantee or endorsement or other instrument under which the Corporation or such Subsidiary is
contingently liable, either directly or indirectly, for borrowed money or interest thereon), other than Permitted Liens, without simultaneously or prior thereto securing, or causing such Subsidiary to secure, indebtedness under the Indenture so that
Securities are secured equally and ratably with or prior to such other indebtedness or liability, except that the Corporation and its 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 10% of Consolidated Net Tangible Assets of
the Corporation. 
 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 

  
 73 

 
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 be deemed to create indebtedness secured by Liens. 

SECTION 1010. Waiver of Certain Covenants. 

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 series set forth in Section 804 or Sections 1006 to 1009, inclusive, or any covenants added to Article Ten pursuant to Section 301 in connection with Securities of such series, 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. 
 ARTICLE 11 

REDEMPTION OF SECURITIES 

SECTION 1101. Applicability of Article. 

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 specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 

SECTION 1102. Election to Redeem; Notice to Trustee. 

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), notify the Trustee of such Redemption Date and of the
principal amount of 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 1103. 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. 
 SECTION 1103. Selection by Trustee of Securities to Be Redeemed. 

If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60
days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by lot in such manner as the Trustee shall deem fair and appropriate and which may 

  
 74 

 provide for the selection for redemption of portions of the principal of Securities of such series; provided,
however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series established pursuant to Section 301. 

The Trustee shall promptly notify the Corporation and the Security Registrar (if other than 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. 

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. 

SECTION 1104. Notice of Redemption. 

Except as otherwise specified as contemplated by Section 301, notice of redemption shall be given in the manner provided for in Section 106 not
less than 30 nor more than 60 days prior to the 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. 

Any notice that is mailed to the Holder of any Securities in the manner provided in Section 106 shall be conclusively presumed to have been
duly given, whether or not such Holder receives the notice. 
 All notices of redemption shall state: 

(1) the Redemption Date, 

(2) the Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 1106, 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 1106 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, 

  
 75 

 (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, and 
 (7) that
the redemption is for a sinking fund, if such is the case. 
 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. 

SECTION 1105. Deposit of Redemption Price. 

On or prior to any Redemption Date, the Corporation shall deposit, with respect to the Securities being redeemed, 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 in the Currency in which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the Redemption Price of, and accrued interest, if any, on, all the Securities which are to be
redeemed on that date. 
 SECTION 1106. Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at
the Redemption Price therein specified in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections
312(b), 312(d) and 312(e)) (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Corporation shall default in the payment of the Redemption Price and accrued interest, if any) such Securities
shall, if the same were interest-bearing, cease to bear interest. 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, however, that installments of interest on 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 Regular Record Date or Special Record Date, as the case may be, 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 or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 

SECTION 1107. Securities Redeemed in Part. 

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 

  
 76 

 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. 

SECTION 1108. Tax Redemption. 

If specified pursuant to Section 301, the Securities of a series will be subject to redemption at any time, in whole but 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 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 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 a date specified in the applicable prospectus supplement, if any
date is so specified, the Corporation 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 a date specified pursuant to Section 301, 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 any change, amendment, application or interpretation shall be officially proposed, which, in any such case, in the Opinion of Counsel to the
Corporation, will result in the Corporation 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 in its business
judgment determines that such obligation cannot be avoided by the use of reasonable measures available to the Corporation; provided however, that (i) no such notice of redemption may be given earlier than 90 or later than 30 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. 
 ARTICLE 12 

SINKING FUNDS 
 SECTION
1201. Applicability of Article. 
 Retirements of Securities of any series pursuant to any sinking fund shall be made in accordance with
the terms of such Securities and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 

  
 77 

 The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund
payment”. If provided for by the terms of Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such series. 
 SECTION 1202. Satisfaction of Sinking Fund
Payments with Securities. 
 Subject to Section 1203, in lieu of making all or any part of any mandatory sinking fund payment with
respect to any Securities of a series in cash, the Corporation may at its option (1) deliver to the Trustee Outstanding Securities of a series (other than any previously called for redemption) theretofore purchased or otherwise acquired by the
Corporation, and/or 
 (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustee by the
Corporation for Securities of such series which have been redeemed either at the election of the Corporation pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of the same series required to be made pursuant to the terms of such Securities as provided for by the terms of
such series; provided, however, that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. 
 SECTION
1203. Redemption of Securities for Sinking Fund. 
 Not less than 30 days prior to each sinking fund payment date for any series of
Securities, the Corporation will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be
satisfied by payment of cash in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b),
312(d) and 312(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 1202 (which Securities will, if not previously delivered, accompany such certificate) and whether
the Corporation intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Corporation shall be obligated to make the cash payment or
payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Corporation to deliver such certificate, the sinking fund payment due on the next succeeding sinking fund payment
date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without, with respect to such payment date, the option to deliver or credit
Securities as provided in Section 1202 and without the right to make any optional sinking fund payment, if any, with respect to such series. 

  
 78 

 Not more than 30 days before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Corporation in the manner provided in Section 1104.
Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. 

On or prior to any sinking fund payment date, the Corporation shall pay to the Trustee or a Paying Agent (or, if the Corporation is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 1003) in cash a sum equal to any interest that will accrue to the date fixed for redemption of Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section 1203. 
 Notwithstanding the foregoing, with respect to a sinking fund for any series of Securities, if at any time
the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not exceed in the aggregate $100,000, the
Trustee, unless requested by the Corporation, shall not give the next succeeding notice of the redemption of Securities of such series through the operation of the sinking fund. Any such unused balance of moneys deposited in such sinking fund shall
be added to the sinking fund payment for such series to be made in cash on the next succeeding sinking fund payment date or, at the request of the Corporation, shall be applied at any time or from time to time to the purchase of Securities of such
series, by public or private purchase, in the open market or otherwise, at a purchase price for such Securities (excluding accrued interest and brokerage commissions, for which the Trustee or any Paying Agent will be reimbursed by the Corporation)
not in excess of the principal amount thereof. 
 ARTICLE 13 

REPAYMENT AT OPTION OF HOLDERS 

SECTION 1301. Applicability of Article. 

Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms
of such Securities and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 

SECTION 1302. Repayment of Securities. 

Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the
terms of such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Corporation covenants that on
or before the Repayment Date it will 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 

  
 79 

 provided in Section 1003) an amount of money in the Currency in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal (or, if so provided by the terms of the Securities
of any series, a percentage of the principal) of and (except if the Repayment Date shall be an Interest Payment Date) accrued interest, if any, on, all the Securities or portions thereof, as the case may be, to be repaid on such date. 

SECTION 1303. Exercise of Option. 

Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form
on the reverse of such Securities. To be repaid at the option of the Holder, any Security so providing for such repayment, with the “Option to Elect Repayment” form on the reverse of such Security duly completed by the Holder (or by the
Holder’s attorney duly authorized in writing), must be received by the Corporation at the Place of Payment therefor specified in the terms of such Security (or at such other place or places of which the Corporation shall from time to time
notify the Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repayment Date. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the
principal amount of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal
amount of such Security surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid
principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for
repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Corporation. 

SECTION 1304. When Securities Presented for Repayment Become Due and Payable. 

If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Corporation on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Corporation shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest. Upon surrender of any
such Security for repayment in accordance with such provisions, the principal amount of such Security so to be repaid shall be paid by the Corporation, together with accrued interest, if any, to the Repayment Date; provided, however, that, in
the case of Securities, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment 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. 

  
 80 

 If the principal amount of any Security surrendered for repayment shall not be so repaid upon
surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue
Discount Securities) set forth in such Security. 
 SECTION 1305. Securities Repaid in Part. 

Upon surrender of any Registered Security which is to be repaid in part only, the Corporation shall execute and the Trustee shall authenticate
and deliver to the Holder of such Security, without service charge and at the expense of the Corporation, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal
amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid. 
 ARTICLE 14

 DEFEASANCE AND COVENANT DEFEASANCE 

SECTION 1401. Option to Effect Defeasance or Covenant Defeasance. 

Except as otherwise specified as contemplated by Section 301 for Securities of any series, the provisions of this Article Fourteen shall apply
to each series of Securities, and the Corporation may, at its option, effect defeasance of the Securities of or within a series under Section 1402, or covenant defeasance of or within a series under Section 1403 in accordance with the terms of such
Securities and in accordance with this Article. 
 SECTION 1402. Defeasance and Discharge. 

Upon the exercise by the Corporation 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 1404 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 1405
and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all of 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 1404 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, 1003 and 1005, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Fourteen. Subject to

  
 81 

 
compliance with this Article Fourteen, the Corporation may exercise its option under this Section 1402 notwithstanding the prior exercise of the option under Section 1403 with respect to such
Securities. 
 SECTION 1403. Covenant Defeasance. 

Upon the exercise by the Corporation 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 804 and Sections 1006 through 1009, and, if specified pursuant to Section 301, their obligations under any other covenant, with respect to such Outstanding Securities on and after the
date the conditions set forth in Section 1404 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(4) or Section 501(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 

SECTION 1404. Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of either Section 1402 or Section 1403 to any Outstanding Securities of or within a
series: 
 (1) The Corporation has deposited or caused to be deposited with the Trustee (or another trustee satisfying the
requirements of Section 607 who shall agree to comply with the provisions of this Article Fourteen 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 such Currency in which such Securities are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of
the Currency in which such Securities are then specified as payable at Stated Maturity) 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 chartered
accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) 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, and (ii) any mandatory sinking fund payments or analogous 

  
 82 

 payments applicable to such Outstanding Securities on the day on which such payments are due and
payable in accordance with the terms of this Indenture and of such Securities; 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) In the case of an election under Section 1402, the Corporation shall have delivered to the Trustee an Opinion of Counsel in
the United States stating that (i) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) 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 U.S. federal income tax purposes as a result of such
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 defeasance had not occurred. 

(3) In the case of an election under Section 1403, 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. 

(4) Either the Corporation has delivered to the Trustee an Opinion of Counsel in Canada or a ruling from Canada Customs
and Revenue Agency to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for Canadian federal, provincial or territorial income tax or other tax purposes as a result of such defeasance or covenant
defeasance and will be subject to Canadian federal or provincial income tax and other 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). 

(5) 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). 

(6) No Event of Default or Default with respect to such Securities shall have occurred and be continuing on the date of
such deposit or, insofar as paragraphs (6) and (7) of Section 501 are concerned, at any time during the period ending on the 91st day 

  
 83 

 
after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 

(7) 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. 
 (8) 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. 

(9) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in
compliance with any additional or substitute terms, conditions or limitations in connection therewith pursuant to Section 301. 

(10) 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 1402 or the covenant defeasance under Section 1403 (as the case may be) have been complied with. 

SECTION 1405. 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 (or other property as may be provided
pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405, the “Trustee”) pursuant to Section 1404 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. 
 Unless otherwise specified with respect to any Security pursuant to Section 301, if, after a deposit referred to
in Section 1404(1) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 312(b) or the terms of such Security to receive payment in a Currency other than that in
which the deposit pursuant to Section 1404(1) has been made in respect of such Security, or (b) a Conversion Event occurs as contemplated in Section 312(d) or 312(e) or by the terms of any Security in respect of which the deposit pursuant to Section
1404(1) has been made, the indebtedness represented by such Security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and interest, if any, on such Security as

 Anything in this Article Fourteen to
the contrary notwithstanding, the Trustee shall deliver or pay to the Corporation from time to time upon request of the Corporation any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section
1404 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof 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. 
 SECTION 1406.
Reinstatement. 
 If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 1405 by reason of any order

deposit had occurred pursuant to Section 1402 or 1403, 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 1405; 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

 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 provided in the manner specified in Section 104 or by having the signature of the person executing the proxy witnessed or guaranteed by
any trust company or bank authorized by Section 104 to certify to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof

of the meeting, unless the meeting shall have been called by the Corporation or by Holders of Securities as provided in Section 1502(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

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 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 1502 and, if

 88 

 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.

 [The Securities are also subject to redemption on [date] in
each year commencing in [year] through the operation of a sinking fund, at a Redemption Price equal to 100% of the principal amount, together with accrued interest to the Redemption Date, all as provided in the Indenture. The sinking fund provides

In the event of redemption [repayment] of this Security in part only, a new Security or Securities for the unredeemed [unpaid] 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

 Exhibit A-5

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 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 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 in New York, New York 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 without coupons in denominations of $1,000 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth, 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. 

No service charge shall be made for any registration of transfer or exchange of Securities, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 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 Trustees 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 neither the Corporation, the Trustee nor 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. For the purposes of the Interest Act (Canada), the yearly rate of interest 

  
 Exhibit A-6 

 which is equivalent to the rate payable hereunder is the rate payable multiplied by the actual number of days in
the year and divided by 360. 
 *[If at any time, (i) the Depositary notifies the Corporation that it is unwilling or unable or no longer
qualifies to continue as Depositary 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, or (ii) the Corporation determines that the Securities shall no longer be represented by a global Security
or Securities, 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 issued 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.
