a Security 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; and 

(2) In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made in a manner

Trustee electronically in accordance with the procedures of such Depository as in effect from time to time in lieu of giving notice to such Depository or such nominee, as the case may be, by mail and all references in this Indenture to the mailing

(iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New
York or a day on which trust companies or banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed. The provisions of this Section 116 shall not be applicable with respect to
any payment due on a Security which is payable in Dollars. 
 Section 117. Extension of Payment Dates. 

In the event that (i) the terms of any Security established in or pursuant to this Indenture permit the Company or any Holder thereof to
extend the date on which any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if any, with respect to such Security is due and payable and (ii) the due date for any such payment shall have been so
extended, then all references herein to the Stated Maturity of such payment (and all references of like import) shall be deemed to refer to the date as so extended. 

Section 118. Immunity of Shareholders, Directors, Officers and Agents of the Company. 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, or for any claim based thereon or otherwise in respect thereof, shall be had against any past, present or future shareholder, incorporator,
employee, officer or director, as such, of the Company or any predecessor or successor to the Company, either directly or through the Company or any such predecessor or 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 and as part of the consideration for the issue of the
Securities; it being expressly understood that, without limitation to the foregoing, this Indenture and the Securities and the obligations created hereunder and thereunder are solely corporate, limited liability company, partnership, limited
partnership or similar obligations, as the case may be, of the Company and that no such Personal liability whatever shall attach to, or is or shall be incurred by, any past, present or future shareholder, incorporator, employee, officer or director,
as such, of the Company or any of its predecessors or successors, or any of them, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in any
Security or implied herefrom or therefrom and that any and all such Personal liability of every type and nature, either at common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such past,
present or future shareholder, incorporator, employee, officer or director, as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in
any Security or implied herefrom or therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issuance of

the Securities. As used in this Section 118, all references to “shareholders” shall be deemed to mean, with respect to any Person, any past, present or future holder or owner of an
equity interest in such Person, including, without limitation, owners or holders of capital stock, limited or general partnership interests and limited liability company interests. 

Section 119. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations
hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or
acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the
banking industry to resume performance as soon as practicable under the circumstances. 
 Section 120. Patriot Act. The parties hereto
acknowledge that in accordance with Section 326 of the Patriot Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information
that identifies each Person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee
to satisfy the requirements of the Patriot Act.

aggregate amount of all Outstanding Securities of such series (or such lesser amount as is permitted by the terms thereof) from time to time endorsed thereon or reflected on the books and records

not be accompanied by an Opinion of Counsel. Notwithstanding the foregoing provisions of this paragraph, in the event a global Security is exchangeable for definitive Securities as provided in Section 305, then, unless otherwise provided in or
pursuant to this Indenture with respect to the Securities of such series, the Trustee shall deliver and redeliver such global Security to the extent necessary to effect such exchanges, shall endorse such global Security to reflect any decrease in
the principal amount thereto resulting from such exchanges and shall take such other actions, all as contemplated by Section 305.

of the Company and the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a global Security, the Holder of such global Security.

indices or other indices), and, if so, the terms and conditions upon which and the method by which such amounts shall be determined and paid or payable;

Securities of such series are to be secured by any property, assets or other collateral and, if so, the applicable collateral, any deletions from, or modifications or additions to, the provisions of Article Fifteen hereof or any other provisions of
this Indenture in connection therewith or in connection with any other instrument or agreement entered into in connection therewith; 
 (23)
if the principal amount payable at the Stated Maturity of any Securities of the series will not be determinable as of any one or more dates prior to the Stated Maturity, the amount which shall be deemed to be the principal amount of such Securities
as of any such date for any purpose thereunder or hereunder, including the principal amount thereof which shall be due and payable upon any Maturity other than the Stated Maturity or which shall be deemed to be Outstanding as of any date prior to
the Stated Maturity (or, in any such case, the manner in which such amount deemed to be the principal amount shall be determined); and 

  
 16 








 (24) any other terms of such Securities (whether or not such other terms are consistent or
inconsistent with any other terms of this Indenture) and any deletions from or modifications or additions to this Indenture in respect of such Securities. 

The terms of the Securities of any series may provide, without limitation, that the Securities shall be authenticated and delivered by the
Trustee on original issue from time to time upon written order of Persons designated in the Board Resolution, Officers’ Certificate or supplemental indenture, as the case may be, pertaining to such series of Securities and that such Persons are
authorized to determine, consistent with such Board Resolution, Officers’ Certificate or supplemental indenture, such terms and conditions of the Securities of such series as are specified in such Board Resolution, Officers’ Certificate or
supplemental indenture. All Securities of any one series need not be issued at the same time and, unless otherwise provided by the Company as contemplated by this Section 301, a series may be reopened from time to time without the consent of
any Holders for issuances of additional Securities of such series. 
 If any of the terms of the Securities of any series shall be
established by action taken by or pursuant to one or more Board Resolutions, such Board Resolutions shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of such series. 

Section 302. Currency; Denominations. Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and interest on
and any Additional Amounts with respect to the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Securities denominated in Dollars shall be issuable in registered form without coupons in
denominations of $1,000 and any integral multiples thereof. 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. Securities shall be executed on behalf of the Company by its Chairman, its Chief
Executive Officer, its President or one of its Vice Presidents and by its Treasurer, one of its Assistant Treasurers, its Secretary or one of its Assistant Secretaries and may (but need not) have its corporate or other seal or a facsimile thereof
reproduced thereon. The signature of any of these officers on the Securities may be manual or facsimile. 
 Securities bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of the Company shall, to the fullest extent permitted by law, 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. 
 At any time and from
time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental
indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order
and subject to the provisions hereof and of such Securities 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 the applicable provisions of Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel to the following effect, which Opinion of
Counsel may contain such assumptions, qualifications and limitations as such counsel shall deem appropriate: 
 (a) the form or forms and
terms of such Securities have been established in conformity with Sections 201 and 301 of this Indenture; and 
 (b) all conditions
precedent set forth in Sections 201, 301 and 303 of this Indenture to the authentication and delivery of such Securities have been complied with and that such Securities, when completed by 

  
 17 








 
appropriate insertions (if applicable), executed by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to
this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws
relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). 

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel at the time
of issuance of each Security, but such opinion, with such modifications as counsel shall deem appropriate, shall be delivered at or before the time of issuance of the first Security of such series. After any such first delivery, any separate request
by the Company that the Trustee authenticate Securities of such series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of
such Securities continue to have been complied with. The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any 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 that is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not
lawfully be taken. 
 Each Security shall be dated the date of its authentication. 

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such
Security a certificate of authentication substantially in the form provided for in Section 202 or 611 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized signatories. Such
certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 

Section 304. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon
Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof 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 of the Company 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 set forth in this
Indenture or the provisions established pursuant to Section 301, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. Except as otherwise provided in or pursuant to this
Indenture, after the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities
upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Except as otherwise provided in or pursuant to this Indenture, upon surrender for cancellation of any one or more temporary
Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions.
Unless otherwise provided in or pursuant to this Indenture with respect to a temporary Security, 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. 
 Section 305. Registration, Transfer and Exchange. With respect to the Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the
Company shall provide for the registration of the Securities of such series and of transfers of the Securities of such series. Such Office or Agency shall be the “Security Registrar” for that series of Securities. Unless otherwise
specified in or pursuant to this Indenture or the Securities, the initial Security Registrar for each 

  
 18 








 
series of Securities shall be as specified in the last paragraph of Section 1002. 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 Securities shall have been appointed by the Company and shall have accepted such appointment.
In the event that the Trustee shall not be or shall cease to be 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 each series of Securities. 
 Except as otherwise provided in or pursuant to this Indenture, upon surrender for
registration of transfer of any Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new
Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions. 

Except as otherwise provided in or pursuant to this Indenture, at the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series.
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. 

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, 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 provided in or pursuant to this Indenture, the global Securities of any series shall be
exchangeable for definitive certificated Securities of such series only if (i) the Depository for such global Securities notifies the Company that it is unwilling or unable to continue as a Depository for such global Securities or at any time
the Depository for such global Securities ceases to be a clearing agency registered as such under the Exchange Act, if so required by applicable law or regulation, and no successor Depository for such Securities shall have been appointed within 90
days of such notification or of the Company becoming aware of the Depository’s ceasing to be so registered, as the case may be, (ii) the Company, in its sole discretion, determines that the Securities of such series shall no longer be
represented by one or more global Securities and executes and delivers to the Trustee a Company Order to the effect that such global Securities shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with respect
to such Securities. 
 If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive
Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding paragraph, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal
amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the Depository (or its custodian) as shall be
specified in the Company Order with respect thereto (which the Company agrees to deliver), and in accordance with instructions given to the Trustee and the Depository (which instructions shall be in writing but need not be contained in or
accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), 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 in
part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged, which shall be in such denominations and registered in such names as shall be specified by the Depository;
provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date. Promptly
following any such exchange in part, such global Security shall be returned by the Trustee to such Depository (or its custodian) or such other Depository (or its custodian) referred to above in accordance with the instructions of the Company
referred to above, and the 

  
 19 








 
Trustee shall endorse such global Security to reflect the decrease in the principal amount thereof resulting from such exchange. If a Security is issued in exchange for any portion of a global
Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest
Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be
payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but shall 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 global Security shall be payable in accordance with the provisions of this Indenture. 
 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 entitling the Holders thereof to the same benefits under this Indenture as the Securities
surrendered upon such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for
exchange or redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such
Security 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, or any redemption or repayment of Securities, or any conversion or exchange of Securities for other types of securities or property, 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, 905 or 1107, upon repayment or repurchase in part of any Security
pursuant to Article Thirteen, or upon surrender in part of any Security for conversion or exchange into Common Shares or other securities or property pursuant to its terms, in each case not involving any transfer. 

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of
or exchange any Securities during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of like tenor and terms and of the same series under Section 1103 and ending at the close of
business on the day of such selection, or (ii) to register the transfer of or exchange any Security, or portion thereof, so selected for redemption, except in the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder pursuant to Article Thirteen and not withdrawn, 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 is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms
and of like principal amount and bearing a number not contemporaneously outstanding. 
 If there be delivered to the Company and to the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security, 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 from and against any
and all loss, liability or expense, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon the Company’s request the Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously
outstanding. 
 Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 

  
 20 








 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 issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute a separate obligation of
the Company, whether or not the destroyed, lost or stolen Security 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 such series
duly issued hereunder. 
 The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular
Securities or generally, shall (to the extent lawful) be 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. 

Section 307. Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved. Unless otherwise
provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Security which shall be payable, and are 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 as of the close of business on the Regular Record Date for such interest. 

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Security which
shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular
Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Security (or a Predecessor Security
thereof) shall be 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 such Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as
in this Clause provided. Thereupon, the Company 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 Company shall promptly notify the Trustee 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 mailed, first-class postage prepaid, to the Holder of such Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days
prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan,
The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the
following clause (2). 
 (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Security 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
payment shall be deemed practicable by the Trustee. 
 Unless otherwise provided in or pursuant to this Indenture or the Securities of any
particular series, at the option of the Company, interest on Securities that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an
account maintained by the payee with a bank located in the United States of America. 

  
 21 








 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. Persons Deemed Owners. Prior to due presentment of a 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 Security is registered in the Security Register as the owner of such Security for the purpose of receiving payment of principal of, any premium and (subject to Sections 305 and 307)
interest on and any Additional Amounts with respect to such Security and for all other purposes whatsoever, whether or not any payment with respect to such Security shall 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. 
 No holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect to such global Security, and such Depository 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. 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 global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any Paying Agent or the Security Registrar from giving
effect to any written certification, proxy or other authorization furnished by the applicable Depository, as a Holder, with respect to a global Security or impair, as between such Depository and the owners of beneficial interests in such global
Security, the operation of customary practices governing the exercise of the rights of such Depository (or its nominee) as the Holder of such global Security. 

Section 309. Cancellation. All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit
against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled
promptly by the Trustee. 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 all Securities so
delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All
cancelled Securities held by the Trustee shall be destroyed by the Trustee in accordance with customary procedures. 
 Section 310. Computation of
Interest. Except as otherwise provided in or pursuant to this Indenture or in the Securities of any series, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. 

ARTICLE FOUR 

SATISFACTION AND DISCHARGE OF INDENTURE 

Section 401. Satisfaction and Discharge. Unless, pursuant to Section 301, the provisions of this Section 401 shall not be applicable
with respect to the Securities of any series, upon the direction of the Company by a Company Order, this Indenture shall cease to be of further effect with respect to any series of Securities specified in such Company Order, and the Trustee, on
receipt of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series, when 

  
 22 








 (1) either 

(a) all Securities of such series theretofore authenticated and delivered (other than (i) Securities of such series which have been
destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and (ii) Securities of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company
and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 

(b) all Securities of such series 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 Company, 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 Company, 
 and the Company, in the case of (i),
(ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable in an amount sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and, to the extent that the Securities of such series provide for the payment of Additional Amounts
thereon and the amount of any such Additional Amounts which are or will be payable with respect to the Securities of such series is at the time of deposit reasonably determinable by the Company (in the exercise by the Company of its sole and
absolute discretion), any Additional Amounts with respect to, such Securities, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be; 

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of
such series; and 
 (3) the Company has delivered to the Trustee an Officers’ 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. 

In the event there are Securities of two or more series Outstanding hereunder, the Trustee shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met. 

Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to
the Trustee under Section 606 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the respective obligations of the Company and the Trustee with respect to the Securities
of such series under Sections 305, 306, 403, 404, 1002 and 1003, any rights of Holders of the Securities of such series (unless otherwise provided pursuant to Section 301 with respect to the Securities of such series) to convert or exchange,
and the obligations of the Company to convert or exchange, such Securities into Common Shares or other securities or property, and, if expressly provided pursuant to Section 301 with respect to the Securities of such series, any rights of
Holders of the Securities of such series to require the Company to repurchase or repay, and the obligations of the Company to repurchase or repay, such Securities at the option of such Holders as contemplated by Article Thirteen hereof, shall
survive, and, if the Securities of such series provide for the payment of Additional Amounts pursuant to Section 1004, the Company will remain obligated, following satisfaction and discharge of this Indenture with respect to the Securities of
such series, to pay Additional Amounts with respect to such Securities as contemplated by Section 1004, to the extent (and only to the extent) that the Additional Amounts payable with respect to such Securities exceed the amount deposited in
respect of such Additional Amounts pursuant to subclause (b) of clause (1) of this Section. 

  
 23 








 Section 402. Defeasance and Covenant Defeasance. 

(1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a series under clause
(2) of this Section 402 or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such series, then such provisions,
together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities, and the Company may at its option
by Board Resolution, at any time, with respect to the Securities of or within such series, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance with the conditions set forth below in this
Section 402. Unless otherwise specified pursuant to Section 301 with respect to the Securities of any series, defeasance under clause (2) of this Section 402 and covenant defeasance under clause (3) of this Section 402
may be effected with respect to any or all of the Outstanding Securities of any series. To the extent that the terms of any Security established in or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which
any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if any, with respect to such Security is due and payable, then unless otherwise provided pursuant to Section 301, the right to extend such date
shall terminate upon defeasance or covenant defeasance, as the case may be. 
 (2) Upon the Company’s exercise of the above option
applicable to this Section 402(2) 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 on the date the conditions set forth in
clause (4) of this Section 402 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, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (5) of this Section 402 and the other Sections of this Indenture referred to in clauses (i) through (iv) of
this paragraph, and shall be deemed 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 Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities to receive, solely (except as provided in clause (ii) below)
from the trust fund described in clause (4)(a) of this Section 402 and as more fully set forth in this Section 402 and Section 403, payments in respect of the principal of (and premium, if any) and interest, if any, on, and
Additional Amounts, if any, with respect to, such Securities when such payments are due, (ii) the obligations of the Company and the Trustee with respect to such Securities under Sections 305, 306, 1002 and 1003 and, if applicable to the
Securities of such series, any rights of Holders of such Securities (unless otherwise provided pursuant to Section 301 with respect to the Securities of such series) to convert or exchange, and the obligations of the Company to convert or
exchange, such Securities into Common Shares or other securities or property, and, if expressly provided pursuant to Section 301 with respect to the Securities of such series, any rights of Holders of the Securities of such series to require
the Company to repurchase or repay, and the obligations of the Company to repurchase or repay, such Securities at the option of such Holders as contemplated by Article Thirteen hereof, and, if the Securities of such series provide for the payment of
Additional Amounts pursuant to Section 1004, the Company will remain obligated, following defeasance of this Indenture with respect to the Securities of such series, to pay Additional Amounts with respect to such Securities as contemplated by
Section 1004, to the extent (and only to the extent) that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to clause 4(a) of this Section 402,
(iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402 and Sections 403 and 404. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise
of its option under Section 402(3) with respect to such Securities. 
 (3) Upon the Company’s exercise of the above option
applicable to this Section 402(3) with respect to any Securities of or within a series, the Company shall be released from its obligations under any covenants applicable to such Securities which are specified pursuant to Section 301 as
being subject to covenant defeasance on and after the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not
“Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, 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 Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth
in any such 

  
 24 








 
covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other
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(5) or 501(11) or otherwise, as the case may be, but, except as specified above,
the remainder of this Indenture and such Securities shall be unaffected thereby. 
 (4) The following shall be the conditions to application
of clause (2) or (3) of this Section 402 to any Outstanding Securities of or within a series: 
 (a) The Company shall
irrevocably have 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 Section 402 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, (1) an amount in Dollars or in such Foreign Currency in which such Securities
are then specified as payable at Stated Maturity or, if such defeasance or covenant defeasance is to be effected in compliance with subsection (f) below, on the relevant Redemption Date, as the case may be, or (2) 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 or, if such defeasance or covenant defeasance is to be effected in compliance with subsection
(f) below, on the relevant Redemption Date, as the case may be) 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, on such Securities, money in an amount, or (3) a combination thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of independent public 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, (y) the principal of (and premium, if any) and interest, if any, on, and, to the extent that such Securities provide for the payment of Additional Amounts thereon and the amount of any such Additional Amounts
which are or will be payable with respect to the Securities of such series is at the time of deposit reasonably determinable by the Company (in the exercise by the Company of its sole and absolute discretion), any Additional Amounts with respect to,
such Outstanding Securities on the Stated Maturity of such principal or installment of principal or interest or the applicable Redemption Date, as the case may be, and (z) any mandatory sinking fund payments or analogous 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. 

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture. 

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities
shall have occurred and be continuing on the date of such deposit, and, solely in the case of defeasance under Section 402(2), no Event of Default with respect to the Company under clauses (8), (9) or (10) of Section 501 with
respect to such Securities or event which with notice or lapse of time or both would become an Event of Default with respect to the Company under clauses (8), (9) or (10) of Section 501 with respect to such Securities shall have
occurred and be continuing at any time during the period ending on and including the 91st day after the date of such deposit (it being understood that this condition to defeasance under Section 402(2) shall not be deemed satisfied until the
expiration of such period). 
 (d) In the case of defeasance pursuant to Section 402(2), the Company shall have delivered to the
Trustee an opinion of independent counsel reasonably acceptable to the Trustee 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 this Indenture
there has been a change in applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion of independent counsel 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; or, in the case of covenant defeasance pursuant to Section 402(3), the Company shall have delivered to the Trustee an opinion of independent counsel reasonably acceptable to the Trustee 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. 

  
 25 








 (e) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance, as the case may be, under this Indenture have been complied with. 

(f) If the monies or Government Obligations or combination thereof, as the case may be, deposited under clause (a) above are sufficient
to pay the principal of, and premium, if any, and interest, if any, on and, to the extent provided in such clause (a), Additional Amounts with respect to, such Securities provided such Securities are redeemed on a particular Redemption Date, the
Company shall have given the Trustee irrevocable instructions to redeem such Securities on such date and to provide notice of such redemption to Holders as provided in or pursuant to this Indenture. 

(g) Notwithstanding any other provisions of this Section 402(4), such defeasance or covenant defeasance shall be effected in compliance
with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 301. 

(5) 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 402(5) and Section 403, the “Trustee”) pursuant to
clause (4)(a) of Section 402 in respect of any Outstanding Securities of any series 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 (other than the Company or any Subsidiary or Affiliate of the Company acting as 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 and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law. 

Unless otherwise specified in or pursuant to this Indenture or any Securities, if, after a deposit referred to in Section 402(4)(a) 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 301 or the terms of such Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to Section 402(4)(a) 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, and Additional Amounts, if any, with respect to, such
Security as the same becomes 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 (x) in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for such Currency in effect on the second Business Day
prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign 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 this Section 402 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities. 

Anything in this Section 402 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 clause (4)(a) of this Section 402 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 a defeasance or covenant defeasance, as applicable, in accordance with this
Section 402. 

  
 26 








 Section 403. Application of Trust Money. Subject to the provisions of the last paragraph of
Section 1003, all money and Government Obligations deposited with the Trustee pursuant to Section 401 or 402 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 Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, interest and Additional Amounts for whose payment such money
has or Government Obligations have been deposited with or received by the Trustee; but such money and Government Obligations need not be segregated from other funds except to the extent required by law. 

Section 404. Reinstatement. If the Trustee (or other qualifying trustee appointed pursuant to Section 402(4)(a)) or any Paying Agent is
unable to apply any moneys or Government Obligations deposited pursuant to Section 401(1) or 402(4)(a) to pay any principal of or premium, if any, or interest, if any, on or Additional Amounts, if any, with respect to the Securities of the
applicable series by reason of any legal proceeding or 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 the
Securities of such series shall be revived and reinstated as though no such deposit had occurred, until such time as the Trustee (or other qualifying trustee) or Paying Agent is permitted to apply all such moneys and Government Obligations to pay
the principal of and premium, if any, and interest, if any, on and Additional Amounts, if any, in respect of the Securities of such series as contemplated by Sections 401 or 402 as the case may be, and Section 403; provided, however, that if
the Company makes any payment of the principal of or premium, if any, or interest if any, on or Additional Amounts, if any, in respect of the Securities of such series following the reinstatement of its obligations as aforesaid, the Company shall be
subrogated to the rights of the Holders of such Securities to receive such payment from the funds held by the Trustee (or other qualifying trustee) or Paying Agent. 

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 the supplemental indenture, Board Resolution or Officers’ Certificate establishing the terms of such series pursuant to this Indenture:

 (1) default in the payment of any interest, if any, on, or any Additional Amounts, if any, payable in respect of any interest, if any,
on, any of the Securities of such series when such interest or such Additional Amounts, as the case may be, become due and payable, and continuance of such default for a period of 30 days; or 

(2) default in the payment of any principal of or premium, if any, on, or any Additional Amounts, if any, payable in respect of any principal
of or premium, if any, on, any of the Securities of such series when due (whether at Maturity or otherwise and whether payable in cash or in Common Shares or other securities or property); or 

(3) default in the deposit of any sinking fund payment or payment under any analogous provision when due with respect to any of the Securities
of such series; or 
 (4) default in the delivery when due of any securities, cash or other property (including, without limitation, any

stating that such notice is a “Notice of Default” hereunder; or

rescinded, prior to written notice of acceleration of the Outstanding Securities of such series; or 
 (7) failure by the Company or any of
its Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $100.0 million, which judgments are not paid, discharged or stayed for a period of 30 days after such judgments become final and
nonappealable; or 
 (8) the Company pursuant to or under or within the meaning of any Bankruptcy Law: 

(i) commences a voluntary case or proceeding seeking liquidation, reorganization or other relief with respect to it or its debts or seeking
the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property; or

Section 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in clauses (8),
(9) or (10) of Section 501 with respect to the Company) occurs and is continuing with respect to Securities of any series, then either the Trustee may, or acting at the director of Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities of each series, shall, or the Holders of 

  
 28 








 
not less than 25% in aggregate principal amount of the Outstanding Securities of such series may, declare the principal of all the Securities of such series, or such lesser amount as may be
provided for in the Securities of such series, and accrued and unpaid interest, if any, thereon to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such
principal or such lesser amount, as the case may be, and such accrued and unpaid interest shall become immediately due and payable. If an Event of Default specified in clause (8), (9) or (10) of Section 501 with respect to the Company
occurs with respect to the Securities of any series, then the principal of all of the Securities of such series, or such lesser amount as may be provided for in the Securities of such series, and accrued an unpaid interest, if any, thereon shall
ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of the Securities of such series. For purposes of clarity, the parties hereto agree that references in
this Indenture to an Event of Default specified in clauses (8), (9) or (10) of Section 501 with respect to the Company shall not include any Event of Default specified in clauses (8), (9) or (10) of Section 501 with
respect to any Significant Subsidiary of the Company. 
 At any time after Securities of any series have been accelerated (whether by
declaration of the Trustee or the Holders or automatically) and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of such series, 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 of money sufficient to pay (or, to the extent that the terms of the Securities of
such series established pursuant to Section 301 expressly provide for payment to be made in Common Shares or other securities or property, Common Shares or other securities or property, together with cash in lieu of fractional shares or
securities to the extent required pursuant to the terms of such Securities, sufficient to pay) 
 (a) all overdue installments of any
interest on any Securities of such series which have become due otherwise than by such declaration of acceleration and any Additional Amounts with respect thereto, 

(b) the principal of and any premium on any Securities of such series which have become due otherwise than by such declaration of acceleration
and any Additional Amounts with respect thereto and, to the extent permitted by applicable law, interest thereon at the rate or respective rates, as the case may be, provided for in or with respect to such Securities, or, if no such rate or rates
are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities, 
 (c) to the extent permitted
by applicable law, interest upon installments of any interest, if any, which have become due otherwise than by such declaration of acceleration and any Additional Amounts with respect thereto at the rate or respective rates, as the case may be,
provided for in or with respect to such Securities, or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities, and 

(d) all sums paid or advanced by the Trustee hereunder and the compensation, fees and expenses, disbursements and advances of the Trustee, its
agents and counsel and all other amounts due the Trustee under Section 606; and 
 (2) all Events of Default with respect to Securities
of such series other than the non-payment of the principal of, any premium and interest on, and any Additional Amounts with respect to Securities of such series which shall have become due solely by such declaration of acceleration, shall have been
cured or waived as provided in Section 513. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 

  
 29 








 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 interest on, or any Additional Amounts payable in respect of any interest on, any
Security when such interest or Additional Amounts, as the case may be, shall have become due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts payable in respect of any principal
of or premium, if any, on, any Security at its Maturity, or 
 (3) default is made in the deposit of any sinking fund payment when due, 

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount of money then due and
payable with respect to such Securities, with interest upon the overdue principal, any premium and, to the extent permitted by applicable law, upon any overdue installments of interest and Additional Amounts at the rate or respective rates, as the
case may be, provided for or with respect to such Securities or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities, and, in addition thereto, such further amount of
money as shall be sufficient to cover the costs and expenses of collection, including the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 606. 

If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the
Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and collect the monies 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 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 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 such Securities or in aid of the exercise of any power granted herein or therein, 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 such other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium,
interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (1) to file and
prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts 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 or counsel) and of the Holders of
Securities allowed in such judicial proceeding, and 
 (2) to collect and receive any monies 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 of Securities 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 of Securities, to pay to the Trustee
any amount due to it for the compensation, fees and expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 606. 

  
 30 








 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder of a Security 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 of a Security in any such proceeding. 
 Section 505. Trustee May Enforce Claims without Possession of Securities. All rights of action
and claims under this Indenture or any of the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery or judgment, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, shall be for the ratable benefit of each and every Holder of a Security in respect of which such judgment has been recovered. 

Section 506. Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article with respect to the
Securities of any series 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 any premium, interest or Additional Amounts, upon presentation of
such Securities, 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 and any predecessor Trustee under Section 606; 
 SECOND: To the payment of the amounts then due
and unpaid upon the Securities for principal and any premium, interest and Additional Amounts in respect of which or for the benefit of which such money or property has been collected, ratably, without preference or priority of any kind, according
to the aggregate amounts due and payable on such Securities for principal and any premium, interest and Additional Amounts; 
 THIRD: The
balance, if any, to the Company. 
 Section 507. Limitations on Suits. No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of such
series; 
 (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series 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 indemnity reasonably satisfactory to the Trustee against the costs, fees and expenses and liabilities which might 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 in principal amount of the Outstanding Securities of such series; 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 or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 

  
 31 








 Section 508. Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional
Amounts. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of, any premium, if any, and (subject to Sections 305 and
307) interest, if any, on and any Additional Amounts with respect to such Security, on the respective Stated Maturity or Maturities therefor specified in such Security (or, in the case of redemption, on the Redemption Date or, in the case of
repayment pursuant to Article Thirteen hereof at the option of such Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and, in the case of any Security which is convertible into or exchangeable for other
securities or property, to convert or exchange, as the case may be, such Security in accordance with its terms, and to institute suit for the enforcement of any such payment and any such right to convert or exchange, and such right shall not be
impaired without the consent of such Holder. 
 Section 509. Restoration of Rights and Remedies. If the Trustee or any Holder of a Security has
instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the
Company, the Trustee and each such Holder shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and each such Holder
shall continue as though no such proceeding had been instituted. 
 Section 510. Rights and Remedies Cumulative. To the extent permitted by
applicable law and except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall 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, to the extent permitted by law, 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 to exercise any right or remedy accruing upon any Event of Default shall, to the extent permitted by applicable law, 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 any Holder of a Security may, to the extent permitted by applicable law, be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder, as
the case may be. 
 Section 512. Control by Holders of Securities. The Holders of a majority in aggregate principal amount of the Outstanding
Securities of any 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 with respect to the Securities of such
series, provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture or with the Securities of
any such series, 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction,
and 
 (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities of such series not joining in such
action. 
 Section 513. Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities of any series on behalf of the Holders of all the Securities of such series may waive any past default hereunder with respect to such series and its consequences, except 

(1) a default in the payment of the principal of, any premium or interest on, or any Additional Amounts with respect to, any Security of such
series, or 

  
 32 








 (2) in the case of any Securities which are convertible into or exchangeable for Common Shares or
other securities or property, a default in any such conversion or exchange, or 
 (3) a default 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, 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 impair any right consequent thereon. 

Section 514. Waiver of Usury, Stay or Extension Laws. The Company covenants that (to the extent that it may lawfully do so) 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 or any usury law or any other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive
the Company from paying all or any portion of the principal of or premium, if any, or interest, if any, on or Additional Amounts, if any, with respect to any Securities as contemplated herein and therein or which may affect the covenants or the
performance of this Indenture or the Securities; and the Company (to the extent that it may lawfully do so) 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 or the Holders, 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 of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted to be taken by it as Trustee, the filing by
any party litigant in such suit of any undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and disbursements, against any party litigant in such suit
having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 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 more than 10% in principal amount of Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest, if any,
on or Additional Amounts, if any, with respect to any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date, and, in the case of repayment at the option of
the Holder pursuant to Article Thirteen hereof, on or after the date for repayment) or for the enforcement of the right, if any, to convert or exchange any Security into Common Shares or other securities in accordance with its terms.

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, coupon or other paper or document, but the Trustee, in

repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section.

any default of the character specified in Section 501(5) or 501(11) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the

 (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

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
Company, by or pursuant to 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 of a Security 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

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 Company, by or pursuant to 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) and shall comply with the applicable requirements of Section 609. 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 in accordance with the applicable requirements of Section 609, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee

with respect to the Securities of such series. 
 (6) The Company 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 by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Securities of such
series as their names and addresses appear in the Security Register. 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. 

(1) Upon the appointment hereunder of any successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and 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 hereunder of the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring Trustee, upon payment of its charges, shall execute
and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to Section 1003, shall duly assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 606. 
 (2) Upon the
appointment hereunder of any successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee 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, such 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, 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 that no Trustee shall be responsible for any notice given to, or received by, or any act or failure to act on the part of any other Trustee hereunder, 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, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance
of the duties and obligations vested in the Trustee under this Indenture with respect to the Securities of that or those series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, 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 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 such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the Securities of that or those series to which the appointment of such successor relates and
subject to Section 1003 shall duly assign, transfer and deliver to such successor Trustee, to the extent contemplated by such supplemental indenture, the 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, subject to its claim, if any, provided for in Section 606. 

(3) Upon request of any Person appointed hereunder as a successor Trustee, the Company shall execute any and all instruments for more fully
and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case may be. 

(4) No Person shall accept its appointment hereunder as a successor Trustee unless at the time of such acceptance such successor Person 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 consolidation to which the Trustee shall be a party, or any Corporation succeeding to all or substantially
all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder (provided that such Corporation shall otherwise be 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 

  
 37 








 
been authenticated but not delivered by the Trustee then in office, any such successor 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 Securities shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities
in either its own name or that of its predecessor Trustee. 
 Section 611. Preferential Collection of Claims Against Company. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other
obligor). 
 Section 612. Appointment of Authenticating Agent. The Trustee may appoint one or more Authenticating Agents acceptable to the
Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption,
partial repayment, partial conversion or exchange for Common Shares or other securities or property, or pursuant to Section 306, and 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. 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, except as provided in or pursuant to this Indenture, shall at all times be a
Corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined
capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. 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 all or substantially all
of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, 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 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 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 appoint a successor Authenticating Agent which shall be acceptable
to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the
Security Register. 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
Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section. If the Trustee makes such payments, it shall be entitled to be reimbursed for such payments, subject to the provisions of
Section 606. 
 The provisions of Sections 308, 603 and 604 shall be applicable to each Authenticating Agent. 

  
 38 








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

This is one of the Securities of the series designated herein referred to in the within-mentioned Indenture. 

 

			
	 [Name of Authenticating Agent],
 as
Authenticating Agent

		
	By:    	 	 
		 	As Authenticating Agent
		
	By:    	 	 
		 	Authorized Signatory


 If all of the Securities of any series may not be originally issued at one time, and if the Trustee does
not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested in writing
(which writing need not be accompanied by or contained in an Officers’ Certificate of the Company), shall appoint in accordance with this Section an Authenticating Agent having an office in a Place of Payment designated by the Company with
respect to such series of Securities.

Agency where Securities of such series may be presented or surrendered for payment, where Securities of such series may be surrendered for registration of transfer or exchange, where Securities of such series that are convertible or exchangeable may
be surrendered for conversion or exchange, and where notices and demands to or upon the Company in respect of the Securities of such series relating thereto 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 the Trustee with the address thereof, such presentations and
surrenders may be made or served at the Corporate Trust Office of the Trustee. 
 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 such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its obligations to maintain an Office or Agency in each Place of Payment for Securities of any series for such purposes. The Company shall 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

Common Shares or other securities or property, initially appoints the Trustee as conversion or exchange agent, as the case may be, for the Securities of such series. The Company may subsequently appoint a different or additional Office or Agency
and, as provided in Section 305, may remove and replace from time to time the Security Registrar. 
 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, it shall, on or before each due date of the principal of, any premium or interest on, or any Additional Amounts
with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which the Securities of such series are payable sufficient to pay the principal,
any premium, interest and Additional Amounts, as the case may be, so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so to act.

 Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the
principal of, or any premium or interest on or any Additional Amounts with respect to, any Securities of such series, deposit with any Paying Agent a sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the
principal, premium, interest and Additional Amounts, as the case may be, so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of its action or failure so to act. 

  
 44 








 The Company shall cause each Paying Agent for any series of Securities other than the Trustee 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 shall: 

(1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to
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 provided in or pursuant to this Indenture; 

(2) give the Trustee 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, any premium or interest on or any Additional Amounts with respect to 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. 

To the extent that the terms of any Securities established pursuant to Section 301 provide that any principal of, or premium or interest, if any, on or
any Additional Amounts with respect to any such Securities is or may be payable in Common Shares or other securities or property, then the provisions of this Section 1003 shall apply, mutatis mutandis, to such Common Shares or
other securities or property. 
 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, such sums to be held by the Trustee upon the same terms as those upon which such 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. 

Subject to any applicable abandoned property laws and except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any Additional Amounts with respect to any Security of any series and remaining unclaimed for two years after
such principal or such premium or interest or Additional Amount shall have 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
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, not later than 30 days after the Company’s request for such repayment, at the expense of the Company
cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Securities of such series, or both, 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 or mailing nor shall it be earlier than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance
of such money then remaining will be repaid to the Company. 
 Section 1004. Additional Amounts. If any Securities of a series provide
for the payment of Additional Amounts by the Company, the Company agrees to pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is mentioned, in
any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series
established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any
provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 

Section 1005. Legal Existence. Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in
full force and effect its legal existence as any type of Corporation (it being understood that nothing in this Section 1005 shall prohibit the Company from changing its legal form from one type of Corporation to another type of Corporation).


  
 45 








 Section 1006. Waiver of Certain Covenants. The Company may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 801, 802, 1002, 1003 or 1005 with respect to the Securities of any series and, if expressly provided pursuant to Section 301 with respect to the Securities of such series, any
additional covenants applicable to the Securities of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive
such compliance in such instance or generally shall have waived compliance 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 in respect of any such term, provision or condition shall remain in full force and effect. 

Section 1007. Company Statement as to Compliance. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a
written statement (which need not be contained in or accompanied by an Officers’ Certificate) signed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company, stating whether or not,
to the best of his or her knowledge, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to notice requirements or periods of grace) and if the Company shall be
in default, specifying all such defaults and the nature and status thereof of which he or she may have knowledge. 
 Section 1008.
Calculation of Original Issue Discount. 
 The Company shall deliver to the Trustee promptly at the end of each calendar year
(i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such
original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time. 
 ARTICLE ELEVEN

 REDEMPTION OF SECURITIES 

Section 1101. Applicability of Article. Redemption of Securities of any series at the option of the Company as permitted or required by the terms
of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) 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 of less than all of the Securities of any series, 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 of such Redemption Date and of the principal amount of Securities of such series to be redeemed and, in the event that the Company shall determine that the Securities of any series to be redeemed
shall be selected from Securities of such series having the same issue date, interest rate or interest rate formula, Stated Maturity and other terms (the “Equivalent Terms”), the Company shall notify the Trustee of such Equivalent Terms.

 In the case of any redemption of Securities (A) prior to the expiration of any restriction on such redemption provided in the terms
of such Securities or elsewhere in this Indenture or (B) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish to the Trustee
an Officers’ Certificate evidencing compliance with such restriction or condition. 
 Section 1103. Selection by Trustee of Securities to be
Redeemed. If less than all of the Securities of any series are to be redeemed or if less than all of the Securities of any series with Equivalent Terms 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 or from the Outstanding Securities of such series with Equivalent Terms, as the case may be, 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 amount of Securities of such series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto. 

  
 46 








 The Trustee shall promptly notify the Company and the Security Registrar (if other than itself)
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 Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed. 

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series or in a notice of redemption, if any Security
selected for partial redemption is converted or exchanged for Common Shares or other securities or property in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted or
exchanged portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as
Outstanding for the purpose of such selection. 
 Section 1104. Notice of Redemption. Notice of redemption shall be given in the manner provided
in Section 106, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the
manner herein provided 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
portions thereof. 
 Any notice that is mailed to the Holder of any Securities in the manner herein provided 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 or, if applicable, the manner in which the Redemption Price will be determined, 
 (3) if less than all Outstanding
Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed, 

(4) that, in case any Security is to be redeemed in part only, on and after the Redemption Date, upon surrender of such Security, the Holder
of such Security 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 shall become due and payable upon each such Security or portion thereof to be redeemed,
(subject, if applicable, to the provisos to the first paragraph of Section 1106), and, if applicable, that interest thereon shall cease to accrue on and after said date, 

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price, 

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

(8) in the case of Securities of any series that are convertible or exchangeable into Common Shares or other securities or property, the then
current conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate, as applicable, and the place or places where and the
Persons to whom such Securities may be surrendered for conversion or exchange, 
 (9) the CUSIP number of such Securities, if any, and 

  
 47 








 (10) if the Redemption Price or any portion thereof shall be payable, at the option of the
Company, in cash or in Common Shares or other securities or property (or a combination thereof), a statement as to whether the Company has elected to pay the Redemption Price in cash or Common Shares or other securities or property or a combination
thereof and, if applicable, the portion of the Redemption Price that is to be paid in cash, Common Shares or other securities or property. 

A notice of redemption published as contemplated by Section 106 need not identify particular Securities to be redeemed. 

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, so long as the above information is provided to the Trustee at the time the notice is given to the Trustee pursuant to Section 1102. 

Section 1105. Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities of any
series called for redemption pursuant to Section 1104, 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
applicable Currency or, if the Redemption Price shall be payable in cash, securities and/or other property, an amount of money in the applicable Currency, securities and/or other property, as the case may be, sufficient to pay the Redemption Price
of all such Securities or portions thereof which are to be redeemed on that date, except that, if the Securities of such series are convertible or exchangeable into Common Shares or other securities or property, no such deposit shall be required
(unless otherwise specified pursuant to Section 301 with respect to the Securities of such series) with respect to any such Securities (or portions thereof) which have been converted or exchanged prior to such Redemption Date. 

Section 1106. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed
(except, in the case of Securities which are convertible or exchangeable into Common Shares or other securities or property, any such Securities which shall have been so converted or exchanged prior to the applicable Redemption Date) shall, on the
Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price; provided, however, that, except as otherwise specified in or pursuant to this Indenture or the
Securities of such series, 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 Regular Record Dates therefor 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 any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security or, if no rate is prescribed therefor
in the Security, at the rate of interest, if any, borne by such Security. 
 Section 1107. Securities Redeemed in Part. Any Security which is to
be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee
duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the
same series, containing identical terms and provisions, 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. If
a Security in global form is so surrendered, the Company shall, if so requested by the Trustee, execute, and the Trustee shall authenticate and deliver to the Depository for such Security in global form as shall be specified in the Company Order
with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

 ARTICLE TWELVE 

SINKING FUNDS 
 Section 1201.
Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such
series issued pursuant to this Indenture. 
 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 such 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 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 and this Indenture. 
 Section 1202. Satisfaction of Sinking Fund
Payments with Securities. The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of
such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), and (2) apply as a credit Securities of such series which have been
redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided 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 sinking fund
payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such series to be redeemed in order to
exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the
next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying
Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company. 

Section 1203. Redemption of Securities for Sinking Fund. Not less than 75 days prior to each sinking fund payment date for any series of
Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory 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 and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing
mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less 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. 
 ARTICLE THIRTEEN

 REPAYMENT AT THE OPTION OF HOLDERS 

Section 1301. Applicability of Article. Securities of any series which are repayable at the option of the Holders thereof before their Stated
Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for
purposes of Section 309, shall not operate as a payment, redemption or 

  
 49 








 
satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the applicable repayment date an amount not less than the repayment price payable by the Company on repayment of such
Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers. 

Unless otherwise expressly stated in this Indenture or pursuant to Section 301 with respect to the Securities of any series or unless the
context otherwise requires, all references in this Indenture to the repayment of Securities at the option of the Holders thereof (and all references of like import) shall be deemed to include a reference to the repurchase or redemption of Securities
at the option of the Holders thereof. 
 ARTICLE FOURTEEN 

SECURITIES IN FOREIGN CURRENCIES 

Section 1401. Applicability of Article. Whenever this Indenture provides for (i) any action by, or the determination of any of the rights of,
Holders of Securities of any series in which not all of such Securities are denominated in the same Currency or (ii) any distribution to Holders of Securities of any series in which not all of such Securities are denominated in the same
Currency, in the absence of any provision to the contrary in or pursuant to this Indenture or the Securities of such series, any amount in respect of any Security denominated in a Currency other than Dollars shall be treated for any such action,
determination or distribution as that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record date with respect to Securities of such series (if any) for such action, determination or
distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such distribution) as the Company may specify in a written notice to the Trustee. 

ARTICLE FIFTEEN 

SECURITY 
 Section 1501.
Security. If so provided pursuant to Section 301 with respect to the Securities of any series, the Securities of such series may be secured by such property, assets or other collateral as may be specified in or pursuant to Section 301.
Any and all terms and provisions applicable to the security for the Securities of such series shall also be provided in or pursuant to Section 301, which may include, without limitation, provisions for the execution and delivery of such
security agreements, pledge agreements, collateral agreements and other similar or related agreements as the Company may elect and which may provide for the Trustee to act as collateral agent or in a similar or other capacity. The Trustee shall
comply with Sections 313(a)(5) and (6) and 313(b)(1) of the Trust Indenture Act and the Company shall comply with Sections 314(b), 314(c) and 314(d) of the Trust Indenture Act, in each case in respect of any secured Securities that may be
outstanding hereunder from time to time. 
 * * * * * 

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.
