Section
1.4 Acts of Holders; Record Dates.


 


Any
request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to
be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor
signed by such Holders in person or by agent duly appointed in writing; and, 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. The Trustee shall promptly deliver to the Company copies of all such instrument or instruments delivered
to the Trustee. 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. Proof of execution of any such instrument or
of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive
in favor of the Trustee and the Company, if made in the manner provided in this Section.



 


The
fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to him or her the execution thereof. Where such execution
is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his or her authority. The fact and date of the execution of any such instrument or writing, or the authority
of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.


 


The
ownership of Securities shall be proved by the Security Register.


 


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


 


The
Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled
to give, make or take any request, demand, authorization, direction, vote, notice, consent, waiver or other action provided or
permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company
may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any
notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph,
the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take
the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall
be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount
of Outstanding Securities of such series on such 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 canceled 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. Promptly after any record date is set pursuant to this paragraph,
the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in
Section 1.6.


 


The
Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled
to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2,
(iii) any request to institute proceedings referred to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in
each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request
or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee
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 canceled 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. Promptly after any record date is set pursuant to this paragraph,
the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set
forth in Section 1.6.


 




    	 	 -9-	 



    	 		 



    

 


With
respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as
the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided
that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto
in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6, on or prior to the
existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date
as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.


 


Without
limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do
so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which
may do so pursuant to such appointment with regard to all or any part of such principal amount.


 


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


 


Any
request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing (or by facsimile transmissions, provided
that oral confirmation of receipt shall have been received) to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust Department, or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder
(unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, personally delivered or sent
via overnight courier to the Company addressed to it at the address of its principal office specified in the first paragraph of
this instrument or at any other address previously furnished in writing to the Trustee by the Company, Attention: Chief Financial
Officer.


 


Section
1.6 Notice to Holders; Waiver.


 


Where
this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, or delivered by hand or overnight courier, to each Holder affected
by such event, at its address as it appears in the Security Register, not later than the latest date (if any), and not earlier
than the earliest date (if any), prescribed for the giving of such notice. Neither the failure to mail or deliver by hand or overnight
courier any notice, nor any defect in any notice so mailed or delivered by hand or overnight courier, to any particular Holder
shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner,
such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall
not be a condition precedent to the validity of any action taken in reliance upon such waiver.


 


In
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 with the approval of the Trustee shall constitute a sufficient notification
for every purpose hereunder.

Indenture Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture

the Company and the Trustee with the consent of the Holders of more than 50% in principal amount of the Securities at the time
Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages
in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder

any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder,

Securities of this series, the Holders of not less than a majority in principal amount of the Securities of this series at the
time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as
Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in
principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or
any premium or interest hereon on or after the respective due dates expressed herein.


 


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

The
Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be
specified as contemplated by Section 3.1. In the absence of any such specified denomination with respect to the Securities of
any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof.


 


Section
3.3 Execution, Authentication, Delivery and Dating.


 


The
Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief
Executive Officer, its principal financial officer, its President or one of its Vice Presidents, attested by its Treasurer, its
Secretary or one of its Assistant Treasurers or Assistant Secretaries. 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 bind the
Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such Securities.


 


At
any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of
such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form
or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, 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 Section 6.1) shall be fully protected in
relying upon, a copy of such Board Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion
of Counsel, with such Opinion of Counsel stating,


 


(1)
if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.1, that such
form has been established in conformity with the provisions of this Indenture;


 


(2)
if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.1, that such
terms have been established in conformity with the provisions of this Indenture; and





 




    	 	 -20-	 



    	 		 



    

 


(3)
that such Securities, when 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 legally binding obligations of the Company enforceable
in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar
laws of general applicability relating to or affecting creditors’ rights and to general equity principles.


 


If
such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of
such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities
and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.



 


Notwithstanding
the provisions of Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at
one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the
Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication
of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued.


 


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 herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has
been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated
and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this Indenture.


 


Neither
the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check,
advice of payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been
assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be liable for
any inaccuracy in such numbers.


 


Section
3.4 Temporary Securities.


 


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


 


If
temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall
be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office
or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and
aggregate principal amount. 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 and tenor.

Section
3.5 Registration; Registration of Transfer and Exchange.


 


The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office
and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the
“Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar”
for the purpose of registering Securities and transfers of Securities as herein provided.


 


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



 


At
the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized
denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office
or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate
and deliver, the Securities that the Holder making the exchange is entitled to receive. All Securities issued upon any registration
of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.


 


Every
Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee)
be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar
duly executed, by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration
of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant
to Section 3.4, 9.6 or 11.7 not involving any transfer.


 


If
the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required
(A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the
case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption
of any such Securities selected for redemption under Section 11.3 and ending at the close of business on the day of such mailing,
or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.


 


The
provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:


 


(1)
Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such
Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such
Global Security shall constitute a single Security for all purposes of this Indenture.


 


(2)
Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling
or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange
Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall
exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated
by Section 3.1.





 




    	 	 -22-	 



    	 		 



    

 


(3)
Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities
issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global
Security shall direct.


 


(4)
Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security
or any portion thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.7 or otherwise, shall be authenticated and
delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof.


 


Section
3.6 Mutilated, Destroyed, Lost and Stolen Securities.


 


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



 


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


 


In
case any such 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 of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute
an original additional contractual 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 that series duly issued hereunder.


 


The
provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Securities.


 


Section
3.7 Payment of Interest; Interest Rights Preserved.


 


Except
as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, interest on any Security which
is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name
that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such
interest.


 


Any
interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment
Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular
Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:


 


(1)
The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or
their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money 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 prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in
this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which
shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special
Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section
1.6, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities
of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2).


 




    	 	 -23-	 



    	 		 



    

 


(2)
The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner
of payment shall be deemed practicable by the Trustee.


 


Subject
to the foregoing provisions of this Section, 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.


 


Subject
to the provisions of Section 14.2, in the case of any Security (or any part thereof) which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than any Security the principal of (or premium, if any,
on) which shall become due and payable, whether at Stated Maturity or by declaration of acceleration or otherwise prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment
Date notwithstanding such conversion and such interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Security (or any one or more Predecessor Securities) is registered at the close of business on such
Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence or in Section 14.2, in the case
of any Security (or any part thereof) which is converted, interest whose Stated Maturity is after the date of conversion of such
Security (or such part thereof) shall not be payable.


 


Section
3.8 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 as the owner of such Security for the purpose of receiving payment
of principal of and any premium and (subject to Section 3.7) any interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall
be affected by notice to the contrary.


 


Section
3.9 Cancellation.


 


All
Securities surrendered for payment, redemption, registration of transfer or 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 shall be promptly canceled
by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued
and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All
canceled Securities held by the Trustee shall be disposed of in accordance with its customary procedures.

as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

(7)
                                         any other Event of Default provided with respect to Securities of that series in the
                                         Board Resolution, supplemental indenture or Officers’ Certificate establishing
                                         that series.


 


Section
5.2 Acceleration of Maturity; Rescission and Annulment.


 


(a)
Unless the Board Resolution, supplemental indenture or Officers’ Certificate establishing such series provides otherwise,
if an Event of Default (other than an Event of Default specified in Section 5.1(5) or 5.1(6)) with respect to Securities of any
series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25%
in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof), and premium, if any, together with 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 amount (or specified amount), and premium, if any, together with accrued and unpaid
interest, if any, thereon, shall become immediately due and payable. If an Event of Default specified in Section 5.1(5) or 5.1(6)
with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series
(or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities
as may be specified by the terms thereof), and premium, if any, together with accrued and unpaid interest, if any, thereon, shall
automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and
payable. Any payments by the Company on the Securities following any such acceleration will be subject to the subordination provisions
of Article 15 to the extent provided therein.


 



(b)
Notwithstanding the foregoing, at the election of the Company, the sole remedy with respect to an Event of Default for the failure
by the Company to comply with its obligations under Section 314(a)(1) of the Trust Indenture Act relating to the Company’s
failure to file any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of
the Exchange Act or of its covenants set forth in Section 7.4 (any such Event of Default, a “Reporting Default”),
shall for the first 180 calendar days after the occurrence of such Reporting Default consist exclusively of the right to receive
additional interest (the “Additional Interest”) on the Securities at an annual rate equal to (i) 0.25% of the principal
amount of the Securities for the first 90 calendar days after the occurrence of such Reporting Default and (ii) 0.50% of the principal
amount of the Securities from the 91st day to, and including, the 180th day after the occurrence of such Reporting Default. If
the Company so elects, the Additional Interest shall accrue on all Outstanding Securities from and including the date on which
such Reporting Default first occurs until such violation is cured or waived and shall be payable as provided in Section 3.7. On
the 181st day after such Reporting Default (if such violation is not cured or waived prior to such 181st calendar day), then the
Trustee or the Holders of not less than 25% in principal amount of the Outstanding securities may declare the principal of, and
premium, if any, together with accrued and unpaid interest, if any, on all such Securities to be due and payable immediately.


 


If
the Company elects to pay the Additional Interest as the sole remedy for the Reporting Default, the Company shall notify in writing,
by a certificate, the Holders, the Paying Agent and the Trustee of such election at any time on or before the close of business
on the first Business Day following the date on which such Event of Default first occurs. Unless and until a Responsible Officer
of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that Additional
Interest is not payable. The Company shall pay the Additional Interest semi-annually in arrears, with the first semi-annual payment
due on the first Interest Payment Date following the date of such Reporting Default, in the same manner as described on the face
of the Security.


 


(c)
At any time after such a declaration of acceleration with respect to Securities of any series has been made 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
a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee,
may rescind and annul such declaration and its consequences if





 



    	 	 -27-	 



    	 		 



     


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


 


(A)
all overdue interest on all Securities of that series,


 


(B)
the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration
of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,


 


(C)
to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor
in such Securities, and


 


(D)
all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; and


 



(2)
all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of
that series that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section
5.13.


 


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


 


Section
5.3 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 any Security when such interest becomes due and payable and such default continues
for a period of 30 days, or


 


(2)
default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, the Company
will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed
therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.


 


If
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 in aid of the exercise of any power granted herein, or to enforce any other proper remedy.


 


Section
5.4 Trustee May File Proofs of Claim.


 


In
case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors,
the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized
under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular,
the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that
the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 6.7. No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent
to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee
in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for

Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date), to convert such Securities in accordance
with Article 14 to the extent that such right to convert is applicable to such Security, and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent of such Holder.


 



Section

If
the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding
has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and
in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored

delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

such direction shall not be in conflict with any rule of law or with this Indenture and the Trustee shall not have determined
that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or any other series, not taking
part in such direction; and


 


(2)
the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction or this Indenture.

Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders
of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except


 


(1)
a default in the payment of the principal of or any premium or interest on any Security of such series as and when the same shall
become due and payable by the terms thereof, otherwise than by acceleration (unless such default has been cured and a sum sufficient
to pay all matured installments of interest, principal and premium, if any, has been deposited with the Trustee), or

in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected.

of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture
Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such
an undertaking or to make such an assessment in any suit instituted by the Company or in any suit for the enforcement of the right
to convert any Security in accordance with Article 14.


 


Section
5.15 Waiver of Usury, Stay or Extension Laws.


 


The
Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter
in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully

THE
TRUSTEE


 


Section
6.1 Certain Duties and Responsibilities.


 


The
duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no
provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured
to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

Section
                                         6.2 Notice of Defaults.


 


If
a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such
series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that
except in the case of a default in the payment of principal of (or premium, if any) or interest on any Securities of such series
or in the payment of any sinking fund installment or any conversion right applicable to Securities of such series, the Trustee
shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in the interests of the holders of Securities of such
series; provided, further, however, that in the case of any default of the character specified in Section 5.1(4)
with respect to Securities of such series, no such notice to Holders shall be given until at least 60 days after the occurrence
thereof. For the purpose of this Section, the term “default” means any event that is, or after notice or lapse of
time or both would become, an Event of Default with respect to Securities of such series.



 


Except
with respect to Section 10.1, the Trustee shall have no duty to inquire as to the performance of the Company with respect to the
covenants contained in Article 10. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except
(i) any Default or Event of Default occurring pursuant to Sections 5.1(1), 5.1(2) and 5.1(3) (defaults in payments on the Securities)
or (ii) any Default or Event of Default of which the Trustee shall have received written notification or obtained actual knowledge.


 


Delivery
of reports, information and documents to the Trustee under Section 7.4 is for informational purposes only and the Trustee’s
receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information
contained therein, including the Company’s compliance with any of their covenants hereunder (as to which the Trustee is
entitled to rely conclusively on Officers’ Certificates).


 


Section
6.3 Certain Rights of Trustee.


 


Subject
to the provisions of Section 6.1:


 


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


 


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


 


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


 


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


 


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





 


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


 



    	 	 -32-	 



    	 		 



     





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


 


Section
                                         6.4 Not Responsible for Recitals or Issuance of Securities.


 


The
recitals contained herein and in the Securities, except the Trustee’s certificates 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, sufficiency or priority of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds
thereof.



 



Section
6.5 May Hold Securities and Act as Trustee under Other Indentures.


 


The
Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal
with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar
or such other agent. Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall prohibit the
Trustee from becoming and acting as trustee under other indentures under which other securities, or certificates of interest of
participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder.


 


Section
6.6 Money Held in Trust.


 


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


 


Section
6.7 Compensation and Reimbursement.


 


The
Company agrees:


 


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


 


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


 


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


 


When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.1(5) or Section 5.1(6) hereof
occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended
to constitute expenses of administration under any applicable bankruptcy, insolvency, reorganization or similar law.

Section
6.8 Conflicting Interests.


 


If
the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act and there is an Event of
Default under the Securities of that series, the Trustee shall either eliminate such interest or resign, to the extent and in
the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted
by the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under
this Indenture with respect to Securities of more than one series.


 



Section
6.9 Corporate Trustee Required; Eligibility.


 


There
shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee
hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture
Act to act as such and has (or if the Trustee is a member of a bank holding company system, its bank holding company has) a combined
capital and surplus of at least $50,000,000. If any such Person or bank holding company publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at
any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.


 


Section
6.10 Resignation and Removal; Appointment of Successor.


 


No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11. The
Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company.
If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within
30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction
for the appointment of a successor Trustee with respect to the Securities of such series.


 


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 to the Company.


 


If
at any time:


 


(1)
the Trustee shall fail to comply with Section 6.8 after written request therefor by the Company or by any Holder who has been
a bona fide Holder of a Security for at least six months, or


 


(2)
the Trustee shall cease to be eligible under Section 6.9 and shall fail to resign after written request therefor by the Company
or by any such Holder, or


 


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


 


then,
in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject
to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.


 


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 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
6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.
If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders
and accepted appointment in the manner required by Section 6.11, the retiring Trustee may petition, or any Holder who has been
a bona fide Holder of a Security of such series for at least six months may petition, on behalf of himself and all others similarly
situated, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.


 



    	 	 -34-	 



    	 		 



     


The
Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series
in the manner provided in Section 1.6. 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
6.11 Acceptance of Appointment by Successor.


 


In
case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, -36- trusts and duties of the retiring Trustee; but,
on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall
duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.


 


In
case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and
deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain
such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood
that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each
such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered
by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.


 



    	 	 -35-	 



    	 		 



     


Upon
request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting
in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph,
as the case may be. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article.


 


Section
6.12 Merger, Conversion, Consolidation or Succession to Business.


 


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


 


Section
6.13 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
6.14 Appointment of Authenticating Agent.


 


The
Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized
to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration
of transfer or partial redemption thereof or pursuant to Section 3.6, 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 shall at all times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having (or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) a combined
capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising

may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or
exchange, where Securities of that series may be surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee
as its agent to receive all such presentations, surrenders, notices and demands. Unless otherwise provided in a supplemental indenture
or pursuant to Section 3.1 hereof, the Place of Payment for any series of Securities shall be 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 obligation to maintain an
office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.


 


Section
10.3 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 will, on or before each
due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.


 


Whenever
the Company shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal
of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount,
such sum to be held as provided by the Trust Indenture Act, 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 will 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 will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance
of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect
of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust
by such Paying Agent for payment in respect of the Securities of that series.


 


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 trusts 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 money.


 


Any
money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of
or any premium or interest on any Security of any series and remaining unclaimed for a period ending on the earlier of the date
that is ten Business Days prior to the date such money would escheat to the State or two years after such principal, premium or
interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day and of general circulation in each Place of Payment,
notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

The
Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof,
an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default
in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and
the nature and status thereof of which they may have knowledge. The fiscal year of the Company currently ends on December 31;

and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as, and to the extent, in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted at all times; provided, however,
that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties
if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in
any material respect to the Holders.


 


Section
10.7 Payment of Taxes and Other Claims.


 


The
Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges levied or imposed upon the Company or upon the income, profits or property of the Company, and (2) all
lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company;
provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged
any such tax, assessment, charge or claim (i) whose amount, applicability or validity is being contested in good faith by appropriate
proceedings or (ii) if the failure to pay or discharge would not have a material adverse effect on the assets, business, operations,
properties or condition (financial or otherwise) of the Company and its subsidiaries, taken as a whole.

as otherwise specified as contemplated by Section 3.1 for Securities of such series, the Company may, with respect to the Securities
of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided
pursuant to Section 3.1(19), 9.1(2), 9.1(7), 10.6 or 10.7 for the benefit of the Holders 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 shall, by
Act of such Holders, either waive such compliance in such instance or generally waive 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.

REDEMPTION
OF SECURITIES


 


Section
11.1 Applicability of Article.


 


Securities
of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 3.1 for such Securities) in accordance with this Article.


 


Section
11.2 Election to Redeem; Notice to Trustee.


 


The
election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated
by Section 3.1 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of
any series (including any such redemption affecting only a single Security), the Company shall, at least 45 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, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities
to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided
in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’
Certificate evidencing compliance with such restriction.


 


Section
11.3 Selection by Trustee of Securities to Be Redeemed.


 


If
less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor
are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata basis, provided that the
unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor
are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and
specified tenor not previously called for redemption in accordance with the preceding sentence.


 


If
any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the
portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion
selected for redemption. Securities that have been converted during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.


 


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


 


The
provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether
such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination)
for such Security.


 


For
all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of
such Securities which has been or is to be redeemed.

Section
11.4 Notice of Redemption.


 


Notice

Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed,
at its address appearing in the Security Register.


 


All
notices of redemption shall state:


 


(1)
the Redemption Date,


 


(2)
the Redemption Price (including accrued interest, if any),


 


(3)
if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification
(and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed
and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal
amount of the particular Security to be redeemed,


 


(4)
in case any Security is to be redeemed in part only, that 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 will become due and payable upon each such Security to be redeemed and, if applicable,
that interest thereon will cease to accrue on and after said date,


 


(6)

CONVERSION
OF SECURITIES


 


Section
14.1 Applicability of Article.


 


The
provisions of this Article shall be applicable to the Securities of any series which are convertible into shares of Common Stock
of the Company, and the issuance of such shares of Common Stock upon the conversion of such Securities, except as otherwise specified
as contemplated by Section 3.1 for the Securities of such series.


 


Section
14.2 Exercise of Conversion Privilege.


 


In
order to exercise a conversion privilege, the Holder of a Security of a series with such a privilege shall surrender such Security
to the Company at the office or agency maintained for that purpose pursuant to Section 10.2, accompanied by a duly executed conversion
notice to the Company substantially in the form set forth in Section 2.6 stating that the Holder elects to convert such Security
or a specified portion thereof. Such notice shall also state, if different from the name and address of such Holder, the name
or names (with address) in which the certificate or certificates for shares of Common Stock, which shall be issuable on such conversion,
shall be issued. Securities surrendered for conversion shall (if so required by the Company or the Trustee) be duly endorsed by
or accompanied by instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the Holder or
its attorney duly authorized in writing; and Securities so surrendered for conversion (in whole or in part) during the period
from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date
(excluding Securities or portions thereof called for redemption during the period beginning at the close of business on a Regular
Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or
if such Interest Payment Date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of
such Security then being converted, and such interest shall be payable to such Holder notwithstanding the conversion of such Security,
subject to the provisions of Section 3.7 relating to the payment of Defaulted Interest by the Company. As promptly as practicable
after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject to Section 3.3, set forth,
or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures supplemental
hereto setting forth the terms of such series of Security, and the surrender of such Security in accordance with such reasonable
regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or agency at which such Security
is surrendered, to such Holder or on its written order, a certificate or certificates for the number of full shares of Common
Stock issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such
Board Resolution, Officers’ Certificate or supplemental indenture, and cash as provided therein in respect of any fractional
share of such Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the date on which such notice and such payment, if required, shall have been received in proper
order for conversion by the Company and such Security shall have been surrendered as aforesaid (unless such Holder shall have
so surrendered such Security and shall have instructed the Company to effect the conversion on a particular date following such
surrender and such Holder shall be entitled to convert such Security on such date, in which case such conversion shall be deemed
to be effected immediately prior to the close of business on such date) and at such time the rights of the Holder of such Security
as such Security Holder shall cease and the person or persons in whose name or names any certificate or certificates for shares
of Common Stock of the Company shall be issuable upon such conversion shall be deemed to have become the Holder or Holders of
record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 3.7, no payment
or adjustment shall be made upon any conversion on account of any interest accrued on the Securities (or any part thereof) surrendered
for conversion or on account of any dividends on the Common Stock of the Company issued upon such conversion.


 




    	-51-



     


    

 


In
the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities
of the same series, of authorized denominations, in aggregate principal amount equal to the unconverted portion of such Security.


 


Section
14.3 No Fractional Shares.


 


No
fractional share of Common Stock of the Company shall be issued upon conversions of Securities of any series. If more than one
Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable
upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof
to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 14.3, any Holder of a Security or
Securities would be entitled to a fractional share of Common Stock of the Company upon the conversion of such Security or Securities,
or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Common Stock is listed or admitted to unlisted trading privileges on a national securities
exchange or market, on the basis of the last reported sale price regular way on such exchange or market on the last trading day
prior to the date of conversion upon which such a sale shall have been effected, or (ii) if such Common Stock is not at the time
so listed or admitted to unlisted trading privileges on a national securities exchange or market, on the basis of the average
of the bid and asked prices of such Common Stock in the over-the-counter market, on the last trading day prior to the date of
conversion, as reported by the National Quotation Bureau, Incorporated or similar organization if the National Quotation Bureau,
Incorporated is no longer reporting such information, or if not so available, the fair market price as determined by the Board
of Directors. For purposes of this Section, “trading day” shall mean each Monday, Tuesday, Wednesday, Thursday and
Friday other than any day on which the Common Stock is not traded on the principal exchange or market on which the Common Stock
is then traded or quoted.


 


Section
14.4 Adjustment of Conversion Price or Conversion Rate.


 


The
conversion price or conversion rate, as the case may be, of Securities of any series that is convertible into Common Stock of
the Company shall be adjusted for any stock dividends, stock splits, reclassifications, combinations or similar transactions in
accordance with the terms of the supplemental indenture or Board Resolutions setting forth the terms of the Securities of such
series.


 


Whenever
the conversion price or conversion rate, as the case may be, is adjusted, the Company shall compute the adjusted conversion price
or conversion rate, as the case may be, in accordance with terms of the applicable Board Resolution or supplemental indenture
and shall prepare an Officers’ Certificate setting forth the adjusted conversion price or conversion rate, as the case may
be, and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed
at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2 and, if different, with
the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion price or conversion rate, as the
case may be, to be mailed, first class postage prepaid, to each Holder of Securities of such series at its address appearing on
the Security Register and to any conversion agent other than the Trustee.

for which approval of any shareholders of the Company is required); or


 


(3)
of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares
of Common Stock, or of any consolidation, merger or share exchange to which the Company is a party and for which approval of any
shareholders of the Company is required), or of the sale of all or substantially all of the assets of the Company; or


 


(4)
of the voluntary or involuntary dissolution, liquidation or winding up of the Company;


 


then
the Company shall cause to be filed with the Trustee, and shall cause to be mailed to all Holders at their last addresses as they
shall appear in the Security Register, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to
the applicable record date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose
of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, or
(ii) the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding
up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled
to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up. If at any time the Trustee shall not be the conversion agent,
a copy of such notice shall also forthwith be filed by the Company with the Trustee.


 


Section
14.6 Reservation of Shares of Common Stock.


 


The
Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common
Stock, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock of the Company then
issuable upon the conversion of all outstanding Securities of any series that has conversion rights.


 


Section
14.7 Payment of Certain Taxes upon Conversion.


 


Except
as provided in the next sentence, the Company will pay any and all taxes that may be payable in respect of the issue or delivery
of shares of its Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of its Common Stock in a
name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made
unless and until the person requesting such issue has paid to the Company the amount of any such tax, or has established, to the
satisfaction of the Company, that such tax has been paid.


 


Section
14.8 Nonassessability.


 


The
Company covenants that all shares of its Common Stock that may be issued upon conversion of Securities will upon issue in accordance
with the terms hereof be duly and validly issued and fully paid and nonassessable.

Section
14.9 Provision in Case of Consolidation, Merger or Sale of Assets.


 


In
case of any consolidation or merger of the Company with or into any other Person, any merger of another Person with or into the
Company (other than a merger which does not result in any reclassification, conversion, exchange or cancellation of outstanding
shares of Common Stock of the Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company, the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case
may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security of a series
then Outstanding that is convertible into Common Stock of the Company shall have the right thereafter (which right shall be the
exclusive conversion right thereafter available to said Holder), during the period such Security shall be convertible, to convert
such Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease by a holder of the number of shares of Common Stock of the Company into which such Security
might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such
holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or merged with or into or which
merged into or with the Company or to which such conveyance, sale, transfer or lease was made, as the case may be (a “Constituent
Person”), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of election, if any, as to the
kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or
lease (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the Company held immediately prior to such
consolidation, merger, conveyance, sale, transfer or lease by others than a Constituent Person or an Affiliate thereof and in
respect of which such rights of election shall not have been exercised (“Non-electing Share”), then for the purpose
of this Section 14.9 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance,
sale, transfer or lease by the holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per
share by a plurality of the Non-electing Shares). Such supplemental indenture shall provide for adjustments which, for events
subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article or in accordance with the terms of the supplemental indenture or Board Resolutions setting forth
the terms of such adjustments. The above provisions of this Section 14.9 shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the Company
to the Holder of each Security of a series that is convertible into Common Stock of the Company as provided in Section 1.6 promptly
upon such execution.


 


Neither
the Trustee nor any conversion agent, if any, shall be under any responsibility to determine the correctness of any provisions
contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property
or cash receivable by Holders of Securities of a series convertible into Common Stock of the Company upon the conversion of their
Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may accept
as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel
with respect thereto, which the Company shall cause to be furnished to the Trustee upon request.


 


Section
14.10 Duties of Trustee Regarding Conversion.


 


Neither
the Trustee nor any conversion agent shall at any time be under any duty or responsibility to any Holder of Securities of any
series that is convertible into Common Stock of the Company to determine whether any facts exist which may require any adjustment
of the conversion price or conversion rate, as the case may be, or with respect to the nature or extent of any such adjustment
when made, or with respect to the method employed, whether herein or in any supplemental indenture, any resolutions of the Board
of Directors or written instrument executed by one or more officers of the Company provided to be employed in making the same.
Neither the Trustee nor any conversion agent shall be accountable with respect to the validity or value (or the kind or amount)
of any shares of Common Stock of the Company, or of any securities or property, which may at any time be issued or delivered upon
the conversion of any Securities and neither the Trustee nor any conversion agent makes any representation with respect thereto.
Subject to the provisions of Section 6.1, neither the Trustee nor any conversion agent shall be responsible for any failure of
the Company to issue, transfer or deliver any shares of its Common Stock or stock certificates or other securities or property
upon the surrender of any Security for the purpose of conversion or to comply with any of the covenants of the Company contained
in this Article 14 or in the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed
by one or more duly authorized officers of the Company.


 


Section
14.11 Repayment of Certain Funds upon Conversion.


 


Any
funds which at any time shall have been deposited by the Company or on its behalf with the Trustee or any other paying agent for
the purpose of paying the principal of, and premium, if any, and interest, if any, on any of the Securities (including, but not
limited to, funds deposited for the sinking fund referred to in Article 12 hereof and funds deposited pursuant to Article 13 hereof)
and which shall not be required for such purposes because of the conversion of such Securities as provided in this Article 14
shall after such conversion be repaid to the Company by the Trustee upon the Company’s written request.

SUBORDINATION
OF SECURITIES


 


Section
15.1 Agreement of Subordination.


 


Except
as otherwise provided in a supplemental indenture or pursuant to Section 3.1, the Company covenants and agrees, and each Holder
of Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject
to the provisions of this Article 15; and each Person holding any Security, whether upon original issue or upon transfer, assignment
or exchange thereof, accepts and agrees to be bound by such provisions.


 


The
payment of the principal of, premium, if any, and interest on all Securities (including, but not limited to, the redemption price
with respect to the Securities called for redemption in accordance with Article 11 as provided in the Indenture) issued hereunder
shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment
in full of all Senior Debt, whether outstanding at the date of this Indenture or thereafter incurred.


 


No
provision of this Article 15 shall prevent the occurrence of any default or Event of Default hereunder.


 


Section
15.2 Payments to Holders.


 


No
payment shall be made with respect to the principal of, or premium, if any, or interest on the Securities (including, but not
limited to, the redemption price with respect to the Securities to be called for redemption in accordance with Article 11 as provided
in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section
15.5, if:


 


(i)
a default in the payment of principal, premium, if any, interest, rent or other obligations due on any Senior Debt occurs and
is continuing (or, in the case of Senior Debt for which there is a period of grace, in the event of such a default that continues
beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Debt) (a “Payment Default”),
unless and until such default shall have been cured or waived or shall have ceased to exist; or


 


(ii)
a default, other than a Payment Default, on any Designated Senior Debt occurs and is continuing that then permits holders of such
Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage
Notice”) from a holder of Designated Senior Debt, a Representative of Designated Senior Debt or the Company (a “Non-Payment
Default”).


 


If
the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be
effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of
the immediately prior Payment Blockage Notice. No Non-Payment Default that existed or was continuing on the date of delivery of
any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice.


 


The
Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of:


 


(2)
in the case of any Payment Default, the date upon which the Payment Default is cured or waived or ceases to exist, or


 




    	-55-



     


    

 


(3)
in the case of a Non-Payment Default, the earlier of (a) the date upon which such Non-Payment Default is cured, waived or ceases
to exist or (b) 179 days after the date on which the applicable Payment Blockage Notice is received by the Trustee,


 


unless
this Article 15 otherwise prohibits the payment or distribution at such time.


 


Upon
any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, reorganization, liquidation, receivership or other proceedings, or upon an assignment for the benefit of creditors
or any marshalling of the assets and liabilities of the Company, or otherwise, all amounts due or to become due upon all Senior
Debt shall first be paid in full in cash or other payment satisfactory to the holders of such Senior Debt, or payment thereof
in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Debt, before any
payment is made on account of the principal of, premium, if any, or interest on the Securities (except payments made pursuant
to Article 4 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution,
winding-up, liquidation, reorganization, assignment for the benefit of creditors or the marshalling of assets and liabilities
of the Company); and upon any such dissolution, winding-up, liquidation, reorganization, assignment for the benefit of creditors
or marshalling of assets and liabilities of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment
by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to
which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article 15, shall (except
as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making
such payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture if received by them or
it, directly to the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held
by such holders, or as otherwise required by law or a court order) or their Representative or Representatives, or to the trustee
or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Debt in full, in cash or other payment satisfactory to the holders
of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt, before
any payment or distribution or provision therefor is made to the Holders of the Securities or to the Trustee.


 


For
purposes of this Article 15, the words, “cash, property or securities” shall not be deemed to include shares of stock
of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization
or readjustment, the payment of which is subordinated at least to the extent provided in this Article 15 with respect to the Securities
to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by
the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Debt
(other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent
of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company
into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article
8 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 15.2 if such other
corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article
8.


 


In
the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the
Trustee or any Holder of Securities in respect of the principal of, premium, if any, or interest on the Securities (including,
but not limited to, the redemption price with respect to the Securities called for redemption in accordance with Article 11 as
provided in the Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph
of Section 15.5, until all Senior Debt has been paid in full in cash or other payment satisfactory to the holders of Senior Debt
or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Securities is accelerated
because of an Event of Default, the Company shall promptly notify holders of Senior Debt of the acceleration.


 




    	-56-



     


    

 


In
the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or
character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited
by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Debt is paid in full in
cash or other payment satisfactory to the holders of such Senior Debt, or provision is made for such payment thereof in accordance
with its terms in cash or other payment satisfactory to the holders of such Senior Debt, such payment or distribution shall be
held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Debt or their Representative or
Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt
may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of
all Senior Debt remaining unpaid to the extent necessary to pay all Senior Debt in full in cash or other payment satisfactory
to the holders of such Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of such
Senior Debt.


 


Nothing
in this Section 15.2 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.7. This Section 15.2
shall be subject to the further provisions of Section 15.5.


 


Section
15.3 Subrogation of Securities.


 


Subject
to the payment in full of all Senior Debt, the rights of the Holders of the Securities shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this Article 15 (equally and ratably
with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company
to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights
of the holders of Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to
the Senior Debt until the principal, premium, if any, and interest on the Securities shall be paid in full; and, for the purposes
of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article 15, and no payment over
pursuant to the provisions of this Article 15, to or for the benefit of the holders of Senior Debt by Holders of the Securities
or the Trustee, shall, as between the Company, its creditors other than holders of Senior Debt, and the Holders of the Securities,
be deemed to be a payment by the Company to or on account of the Senior Debt; and no payments or distributions of cash, property
or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article 15,
which would otherwise have been paid to the holders of Senior Debt shall be deemed to be a payment by the Company to or for the
account of the Securities. It is understood that the provisions of this Article 15 are and are intended solely for the purposes
of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the Senior Debt, on the
other hand.


 


Nothing
contained in this Article 15 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the
Company, its creditors other than the holders of Senior Debt, and the Holders of the Securities, the obligation of the Company,
which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and interest
on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall
affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of the Senior
Debt, nor shall anything herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 15 of the holders
of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy.


 


Upon
any payment or distribution of assets of the Company referred to in this Article 15, the Trustee, subject to the provisions of
Section 6.1, and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate
of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered
to the Trustee or to the Holders of the securities, for the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon and
all other facts pertinent thereto or to this Article 15.

Section
15.4 Authorization to Effect Subordination.


 


Each
Holder of a Security by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf
to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 15 and appoints
the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper
proof of claim or proof of debt in the form required in any proceeding referred to in Section 5.4 hereof at least 30 days before
the expiration of the time to file such claim, the holders of any Senior Debt or their representatives are hereby authorized to
file an appropriate claim for and on behalf of the Holders of the Securities.


 


Section
15.5 Notice to Trustee.


 


The
Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee
and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the
Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 15. Notwithstanding the provisions
of this Article 15 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article 15, unless and until a Responsible Officer of the Trustee shall have received written notice
thereof at the Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative or
a holder or holders of Senior Debt or from any trustee therefor; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Section 6.1, shall be entitled in all respects to assume that no such facts exist; provided that
if on a date not fewer than two Business Days prior to the date upon which by the terms hereof any such monies may become payable
for any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest on any Security)
the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 15.5, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to
apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may
be received by it on or after such prior date.


 


Notwithstanding
anything in this Article 15 to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited
with it pursuant to Section 4.1, and any such payment shall not be subject to the provisions of Section 15.1 or 15.2.


 


The
Trustee, subject to the provisions of Section 6.1, shall be entitled to rely on the delivery to it of a written notice by a Representative
or a person representing himself to be a holder of Senior Debt (or a trustee on behalf of such holder) to establish that such
notice has been given by a Representative or a holder of Senior Debt or a trustee on behalf of any such holder or holders. The
Trustee shall not be required to make any payment or distribution to or on behalf of a holder of Senior Debt pursuant to this
Article 15 unless it has received satisfactory evidence as to the amount of Senior Debt held by such person, the extent to which
such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person
under this Article 15.


 


Section
15.6 Trustee’s Relation to Senior Debt.


 


The
Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 15 in respect of any Senior Debt
at any time held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the
Trustee of any of its rights as such holder.


 


With
respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article 15, and no implied covenants or obligations with respect to the holders of Senior
Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Debt and, subject to the provisions of Section 6.1, the Trustee shall not be liable to any holder of Senior Debt (i)
for any failure to make any payments or distributions to such holders or (ii) if it shall pay over or deliver to Holders of Securities,
the Company or any other Person money or assets to which any holder of Senior Debt shall be entitled by virtue of this Article
15 or otherwise.

Section
15.7 No Impairment of Subordination.


 


No
right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Company, the Trustee or any Holder of Securities with the terms, provisions
and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with.


 


Section
15.8 Certain Conversions/Exchanges Deemed Payment.


 


For
the purposes of this Article 15 only, (1) the issuance and delivery of junior securities upon conversion or exchange of Securities
in accordance with Article 14 or otherwise (except upon conversion of the Securities in accordance with their terms) shall not
be deemed to constitute a payment or distribution on account of the principal of (or premium, if any) or interest on Securities
or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash (except in
satisfaction of fractional shares pursuant to Section 14.3), property or securities (other than junior securities) upon conversion
or exchange of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes
of this Section 15.8, the term “junior securities” means (a) shares of any stock of any class of the Company, or (b)
securities of the Company which are subordinated in right of payment to all Senior Debt which may be outstanding at the time of
issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so
subordinated as provided in this Article. Nothing contained in this Article 15 or elsewhere in this Indenture or in the Securities
is intended to or shall impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of Securities,
the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article
14.


 


Section
15.9 Article Applicable to Paying Agents.


 


If
at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the
term “Trustee” as used in this Article shall (unless the context otherwise requires) be construed as extending to
and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in
this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 15.5
shall not apply to the Company or any Affiliate of the Company if the Company or such Affiliate acts as Paying Agent. The Trustee
shall not be responsible for the actions or inactions of any other Paying Agents (including the Company if acting as its own Paying
Agent) and shall have no control of any funds held by such other Paying Agents.


 


Section
15.10 Senior Debt Entitled to Rely.


 


The
holders of Senior Debt (including, without limitation, Designated Senior Debt) shall have the right to rely upon this Article
15, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such
holders shall have agreed in writing thereto.


 


Section
15.11 Reliance on Judicial Order or Certificate of Liquidating Agent.


 


Upon
any payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders shall be entitled
to rely upon any order or decree entered by any court of competent jurisdiction in which such dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company or bankruptcy,
insolvency, receivership or other like proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other person making such payment or distribution, delivered
to the Trustee or to the Holders, for the purpose of ascertaining the persons entitled to participate in such payment or distribution,
the holders of Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this Article.


 


Section
15.12 Trust Monies Not Subordinated.


 


Notwithstanding
anything contained herein to the contrary, payments from money, U.S. Government Obligations and/or Foreign Government Obligations
held in trust under Article 4 or Article 13 by the Trustee for the payment of the principal of, premium, if any, and interest
on the Securities shall not be subordinated to the prior payment in full of any Senior Debt of the Company or subject to the restrictions
set forth in this Article 15, and none of the Holders shall be obligated to pay over any such amount to the Company or any holder
of Senior Debt of the Company or any other creditor of the Company.
