instruments of substantially similar tenor signed by such Holders in Person or by an agent duly appointed in writing. Except as
herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the
holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the
Trust Indenture Act) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in
the manner provided in this Section.

(4)           If
the Company shall solicit from the Holders of any Securities any request, demand, authorization, direction, notice, consent, waiver
or other Act, the Company may at its option (but is not obligated to), by Board Resolution fix in advance a record date for the
determination of Holders of Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver
or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of Securities of record at the close of business on such
record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders of Securities shall be deemed effective unless it shall become effective pursuant to the provisions
of this Indenture not later than six months after the record date. Nothing in this paragraph shall be construed to prevent the
Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount
of Outstanding Securities of the relevant series on the date such action is taken.


 


(5)           Any
request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying
Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.


 


Section
105.           Notices, etc, to Trustee and Company.

permitted by this Indenture to be made upon, given or furnished to, or filed with,

Trustee by any Holder or the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing
to or with the Trustee at its Corporate Trust Office, or


 


(2)           the
Company by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided)

Section
106.           Notice to Holders of Securities;
Waiver. Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice
to Holders of Securities of any event,


 


(1)           such
notice shall be sufficiently given to Holders of Securities if in writing and mailed, first-class postage prepaid, to each Holder
of 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 acceptable to
the Trustee shall constitute a sufficient notification for every purpose hereunder.


 


Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event,
and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee,
but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

may be, in respect of such Security may be given by the Company or the 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 of any such notice shall be deemed to mean, solely as concerns
the notice given by the Company or the Trustee to such Depository or its nominee, as the case may be, the electronic transmission
of such notice as aforesaid, mutatis mutandis.

any provision hereof limits, qualifies or conflicts with any duties under any required provision of the Trust Indenture Act
imposed hereon by Section 318(c) thereof, such required provision of the Trust Indenture Act shall control.


 


Section 109.           Effect

and shall not affect the construction hereof.


 


Section
110.           Successors and Assigns.  All
covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or
not.

legality and enforceability of the remaining provisions shall not, to the fullest extent permitted by law, in any way be affected
or impaired thereby.

The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may have to the laying of the venue

that the designation and appointment of the Process Agent as such authorized agent shall become effective immediately without any

immunity in respect of its obligations under this Indenture to the extent permitted by law.

such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not

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

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.

305, then, unless otherwise provided in or pursuant to this Indenture with respect to the Securities of such series, the Trustee

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

the extent to which, or the manner in which, any interest payable on a temporary global Security will be paid if other than in

Indenture in connection therewith or in connection with any other instrument or agreement entered into in connection therewith;


 


(23)        if

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

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.


 






    	17



    	 



    

 


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 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.


 



    	18



    	 



    

 


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 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.


 






    	19



    	 



    

 


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 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.


 


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).


 






    	21



    	 



    

 


(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.


 


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.

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


 


(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


 






    	23



    	 



    

 


(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.


 


Section 402.           Defeasance
and Covenant Defeasance. 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.


 






    	24



    	 



    

 


(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 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.


 






    	25



    	 



    

 


(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.


 


(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.


 






    	26



    	 



    

 


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.


 


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

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.

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 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,


 






    	29



    	 



    

 


(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.


 


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.


 


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.


 



    	31



    	 



    

 





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.


 


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.


 






    	32



    	 



    

 


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


 


(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.

be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently evidenced by a
Board Resolution;


 


(3)           whenever

Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities, except the Trustee’s
certificate of authentication, shall be taken as the statements of the Company and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Securities and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility

Hold Securities. The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other Person that may
be an agent of the Trustee or the Company, in its individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other Person.


 


Section 605.           Money

(1)           to

(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

held or collected by the Trustee as such, except funds held in trust for the payment of principal of, or premium or interest on
or any Additional Amounts with respect to Securities.


 


Any compensation or expense incurred by
the Trustee after a default specified by Section 501(8), (9) or (10) is intended to constitute an expense of administration under
any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 606 shall include any predecessor
Trustee but the negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under this Section
606. The provisions of this Section 606 shall, to the extent permitted by law, survive any termination of this Indenture (including,
without limitation, termination pursuant to any Bankruptcy Laws) and the resignation or removal of the Trustee.

If the instrument of acceptance by a successor Trustee required by Section 609 shall not have been delivered to the Trustee within
30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction
for the appointment of a successor Trustee with respect to such series.


 


(3)           The
Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series, delivered to the Trustee and the Company.


 


(4)           If
at any time:


 


(a)           the
Trustee shall fail to comply with the obligations imposed upon it under Section 310(b) of the Trust Indenture Act with respect

(5)           If
the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the 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

petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

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. 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.

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

(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.

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.

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 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.


 



    	38



    	 



    

 


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.


 


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.

amend or supplement any provision contained herein, in any supplemental indenture or in any Securities (which amendment or supplement
may apply to one or more series of Securities or to one or more Securities within any series as specified in such supplemental
indenture), provided that such amendment or supplement does not apply to any Outstanding Security issued prior to the date
of such supplemental indenture and entitled to the benefits of such provision.

the Stated Maturity of the principal of, or premium, if any, or any installment of interest, if any, on, or any Additional Amounts,
if any, with respect to, any Security, or reduce the principal amount thereof or the premium, if any, thereon or the rate (or modify
the calculation of such rate) of interest thereon, or reduce the amount payable upon redemption thereof, whether such redemption
is mandatory or at the option of the Company, or upon repayment thereof at the option of the Holder, or reduce any Additional Amounts
payable with respect thereto, or change the obligation of the Company to pay Additional Amounts pursuant to Section 1004 (except
as contemplated by Section 801(1) and permitted by Section 901(1)), or reduce the amount of the principal of any Original Issue
Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section
502 or the amount thereof provable in bankruptcy pursuant to Section 504, or adversely affect the right of repayment at the option
of any Holder as contemplated by Article Thirteen, or change the Place of Payment where or the Currency in which the principal
of, any premium or interest on, or any Additional Amounts with respect to any Security is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after
the Redemption Date or, in the case of repayment pursuant to Article Thirteen at the option of the Holder, on or after the date
for repayment) in each case as such Stated Maturity, Redemption Date or date for repayment may, if applicable, be extended in accordance
with the terms of such Security, or in the case of any Security which is convertible into or exchangeable for other securities
or property, impair the right to institute suit to enforce the right to convert or exchange such Security in accordance with its
terms, or

the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any
such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions
of this Indenture or certain defaults hereunder and their consequences) provided for in Section 513 or 1006 of this Indenture,
or

any of the provisions of this Section, Section 513 or Section 1006, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security
affected thereby.


 


A supplemental indenture which changes or
eliminates any covenant or other provision of this Indenture which shall have been included solely for the benefit of one or more
particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any
other series.


 


Anything in this Indenture to the contrary
notwithstanding, if more than one series of Securities is Outstanding, the Company shall be entitled to enter into a supplemental
indenture under this Section 902 with respect to any one or more series of Outstanding Securities without entering into a supplemental
indenture with respect to any other series of Outstanding Securities.


 


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

in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

COVENANTS


 


Section 1001.           Payment
of Principal, Premium, Interest and Additional Amounts. The Company covenants and agrees for the benefit of the Holders of
the Securities of each series that it will duly and punctually pay the principal of, any premium and interest on and any Additional
Amounts with respect to the Securities of such series, whether payable in cash, Common Shares or other securities or property,
in accordance with the terms thereof and this Indenture.


 


Section 1002.           Maintenance
of Office or Agency. The Company shall maintain in each Place of Payment for any series of Securities an Office or 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 provided in or pursuant
to this Indenture (including, without limitation, pursuant to Section 301 with respect to the Securities of any series), the Company
hereby designates the place where the Trustee shall from time to time maintain its Corporate Trust Office as the Company’s
Office or Agency for such purpose and initially appoints the Trustee as the Security Registrar for each series of Securities and,
if the Securities of any series are convertible into or exchangeable for 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.


 


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).


 


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.

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.


 


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.


 






    	47



    	 



    

 


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


 


(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.


 






    	48



    	 



    

 


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.

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.

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 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.

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.
