SECTION
105.        ACTS OF HOLDERS; RECORD DATES.

request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given 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 an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective
when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments and so voting at any
such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding of any Person
of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved
in the manner provided in Section 1306.


 


The Company may set in
advance a record date for purposes of determining the identity of Holders of Registered Securities entitled to vote or consent
to any action by vote or consent authorized or permitted under this Indenture. If not set by the Company prior to the first solicitation
of a Holder of Registered Securities of such series made by any Person in respect of any such action, or in the case of any such
vote, prior to such vote, the record date for any such action or vote shall be the later of 30 days prior to such first solicitation
of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation. If a record
date is fixed, those Persons who were Holders of Outstanding Registered Securities at such record date (or their duly designated
proxies), and only those Persons, shall be entitled with respect to such Securities to take such action by vote or consent or to
revoke any vote or consent previously given, whether or not such Persons continue to be Holders after such record date. Promptly
after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice thereof to be given
to the Trustee in writing in the manner provided in Section 106 and to the relevant Holders as set forth in Section 107.


 


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


 


(3)         The
principal amount and serial numbers of Registered Securities held by any Person, and the date of holding the same, shall be proved
by the Security Register.

(4)         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. Any Holder or subsequent Holder may revoke the request,
demand, authorization, direction, notice, consent or other Act as to his Security or portion of his Security; provided,
however, that such revocation shall be effective only if the Trustee receives the notice of revocation before the date the
Act becomes effective.


 


SECTION
106.        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
to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Administration, or


 


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


 


The Company or the Trustee,
by notice to the other, may designate additional or different addresses for subsequent notices or communications.


 


All notices and communications
(other than those sent to the Trustee) shall be deemed to have been duly given: at the time delivered by hand, if personally delivered;
five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt acknowledged, if telecopied; and
the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next-day delivery. All
notices and communications to the Trustee shall be deemed duly given and effective only upon receipt.


 


Any notice or communication
to a Holder shall be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier
guaranteeing next-day delivery to its address shown on the Security Register. Any notice or communication shall also be so mailed
to any Person described in TIA Section 313(c), to the extent required by the TIA. Failure to mail a notice or communication to
a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.


 


If a notice or communication
is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.


 


If the Company mails
a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.


 


SECTION
107.        NOTICE TO HOLDERS; WAIVER.

Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice.


 




    	 	-11-	 



     


    

 


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 to Holders
of Registered Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient
notification for every purpose hereunder. In any case in which notice to Holders of Registered Securities is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security, shall
affect the sufficiency of such notice with respect to other Holders of Registered Securities.


 


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


 


SECTION
108.        CONFLICT WITH TRUST INDENTURE ACT.


 


If any provision hereof
limits, qualifies or conflicts with any provision of the Trust Indenture Act or another provision hereof required to be included
in this Indenture by any of the provisions of the Trust Indenture Act, such provision of the Trust Indenture Act shall control.
If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded,
the former provision shall be deemed to apply to this Indenture as so modified or to be excluded.

the remaining provisions shall not in any way be affected or impaired thereby.


 


SECTION
112.        BENEFITS OF INDENTURE.


 


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

Securities shall be governed by and construed in accordance with the laws of the State of New York, but without giving effect to

Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment,

as permitted by Section 304, the form thereof shall be established as provided in the preceding sentence. A copy of the Board Resolution
establishing the form or forms of Securities of any series (or any such temporary global Security) shall be delivered to the Trustee
at or prior to the delivery of the Company Order contemplated by Section 303 for the authentication and delivery of such Securities
(or any such temporary global Security).


 




    	 	-13-

	 	By	 
	 	 	AUTHORIZED OFFICER”


 


SECTION
203.        SECURITIES IN GLOBAL FORM.


 


If Securities of a series
are issuable in global form, as contemplated by Section 301, then, notwithstanding clause (10) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein
and may provide that it shall represent the aggregate amount of Outstanding Securities from time to time endorsed thereon and that
the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced to reflect exchanges. Any endorsement
of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified
in such Security or in a Company Order to be delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions
of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in
the manner and upon instructions given by the Person or Persons specified in such Security or in the applicable Company Order.
If a Company Order pursuant to Section 303 or 304 has been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section
103 and need not be accompanied by an Opinion of Counsel.


 


The provisions of the
last sentence of Section 303 shall apply to any Security in global form if such Security was never issued and sold by the Company
and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with
Section 103 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities
represented thereby, together with the written statement contemplated by the last sentence of Section 303.

Notwithstanding the provisions
of Sections 201 and 307, unless otherwise specified as contemplated by Section 301, payment of principal of (and premium, if any)
and interest on any Security in permanent global form shall be made to the Person or Persons specified therein.


 


Notwithstanding the provisions
of Section 308 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company or of the
Trustee shall treat a Person as the Holder of such principal amount of Outstanding Securities represented by a global Security
as shall be specified in a written statement, if any, of the Holder of such global Security, which is produced to the Security
Registrar by such Holder.


 


Global Securities may
be issued in either temporary or permanent form. Permanent global Securities will be issued in definitive form.


 


SECTION
204.        BOOK-ENTRY SECURITIES.


 


Notwithstanding any provision
of this Indenture to the contrary:


 


(a)          At
the discretion of the Company, any Registered Security may be issued from time to time, in whole or in part, in permanent global
form registered in the name of a Depositary, or its nominee. Each such Registered Security in permanent global form is hereafter
referred to as a “Book-Entry Security.” Subject to Section 303, upon such election, the Company shall execute, and
the Trustee or an Authenticating Agent shall authenticate and deliver, one or more Book-Entry Securities that (i) are denominated
in an amount equal to the aggregate principal amount of the Outstanding Securities of such series if elected in whole or such lesser
amount if elected in part, (ii) are registered in the name of the Depositary or its nominee, (iii) are delivered by the Trustee
or an Authenticating Agent to the Depositary or pursuant to the Depositary’s instructions and (iv) bear a legend in substantially
the following form (or such other form as the Depositary and the Company may agree upon):


 


UNLESS THIS SECURITY IS PRESENTED
BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY], TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF [NOMINEE OF THE DEPOSITARY] OR IN SUCH OTHER NAME AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY] (AND ANY PAYMENT IS MADE TO [NOMINEE OF THE DEPOSITARY] OR TO SUCH OTHER ENTITY AS
IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY]), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, [NOMINEE OF THE DEPOSITARY], HAS AN INTEREST HEREIN.


 


(b)          Any
Book-Entry Security shall be initially executed and delivered as provided in Section 303. Notwithstanding any other provision of
this Indenture, unless and until it is exchanged in whole or in part for Registered Securities not issued in global form, a Book-Entry
Security may not be transferred except as a whole by the Depositary to a nominee of such Depositary, by a nominee of such Depositary
to such Depositary or another nominee of such Depositary, or by such Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.


 




    	 	-15-	 



     


    

 


(c)          If
at any time the Depositary notifies the Company or the Trustee that it is unwilling or unable to continue as Depositary for any
Book-Entry Securities, the Company shall appoint a successor Depositary, whereupon the retiring Depositary shall surrender or cause
the surrender of its Book-Entry Security or Securities to the Trustee. The Trustee shall promptly notify the Company upon receipt
of such notice. If a successor Depositary has not been so appointed by the effective date of the resignation of the Depositary,
the Book-Entry Securities will be issued as Registered Securities not issued in global form, in an aggregate principal amount equal
to the principal amount of the Book-Entry Security or Securities theretofore held by the Depositary.


 


The Company
may at any time and in its sole discretion determine that the Securities shall no longer be Book-Entry Securities represented by
a global certificate or certificates, and will so notify the Depositary. Upon receipt of such notice, the Depositary shall promptly
surrender or cause the surrender of its Book-Entry Security or Securities to the Trustee. Concurrently therewith, Registered Securities
not issued in global form will be issued in an aggregate principal amount equal to the principal amount of the Book-Entry Security
or Securities theretofore held by the Depositary.


 


Upon any
exchange of Book-Entry Securities for Registered Securities not issued in global form as set forth in this Section 204(c), such
Book-Entry Securities shall be cancelled by the Trustee, and Securities issued in exchange for such Book-Entry Securities pursuant
to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Book-Entry Securities,
pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee or any
Authenticating Agent shall deliver such Securities to the Persons in whose names such Securities are so registered.


 


(d)          The
Company and the Trustee shall be entitled to treat the Person in whose name any Book-Entry Security is registered as the Holder
thereof for all purposes of the Indenture and any applicable laws, notwithstanding any notice to the contrary received by the Trustee
or the Company; and the Trustee and the Company shall have no responsibility for transmitting payments to, communication with,
notifying, or otherwise dealing with any beneficial owners of any Book-Entry Security. Neither the Company nor the Trustee shall
have any responsibility or obligations, legal or otherwise, to the beneficial owners or to any other party including the Depositary,
except for the Holder of any Book-Entry Security; provided however, notwithstanding anything herein to the contrary,
(i) for the purposes of determining whether the requisite principal amount of Outstanding Securities have given, made or taken
any request, demand, authorization, direction, notice, consent, waiver, instruction or other action hereunder as of any date, the
Trustee shall treat any Person specified in a written statement of the Depositary with respect to any Book-Entry Securities as
the Holder of the principal amount of such Securities set forth therein and (ii) nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or Trustee, from giving effect to any written certification, proxy or other authorization
furnished by a Depositary with respect to any Book-Entry Securities, or impair, as between a Depositary and holders of beneficial
interests in such Securities, the operation of customary practices governing the exercise of the rights of the Depositary as Holder
of such Securities.

    	 	-18-	 



     


    

 


All Securities of any
one series shall be substantially identical except, in the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined
in the manner provided, in the Officers’ Certificate referred to above or in any such indenture supplemental hereto.


 


All Securities of any
one series need not be issued at the same time and, unless otherwise provided in such Board Resolution or supplemental indenture,
a series may be reopened for issuances of additional Securities of such series pursuant to a Board Resolution or in any indenture
supplemental hereto.


 


At the option of the
Company, interest on the Registered Securities of any series that bears interest may be paid by mailing a check or otherwise transmitting
payment to the address of any Holder as such address shall appear in the Security Register.


 


If any of the terms of
the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action together
with such Board Resolution shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee
at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series.


 


SECTION
302.        DENOMINATIONS.


 


The Securities of each
series shall be issuable in such denominations as shall be specified as contemplated by Section 301. In the absence of any such
provisions with respect to the Securities of any series, the Registered Securities of such series denominated in Dollars shall
be issuable in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Unless otherwise provided as contemplated
by Section 301 with respect to any series of Securities, any Securities of a series denominated in a currency other than Dollars
shall be issuable in denominations that are the equivalent, as determined by the Company by reference to the noon buying rate in
the City of New York for cable transfers for such currency, as such rate is reported or otherwise made available by the Federal
Reserve Bank of New York, on the applicable issue date for such Securities, of $2,000 and any integral multiple of $1,000 in excess
thereof.


 


SECTION
303.        EXECUTION, AUTHENTICATION, DELIVERY AND DATING.


 


The Securities shall
be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, its Chief Financial
Officer, its Treasurer or one of its Vice Presidents, under its corporate seal reproduced thereon or affixed thereto attested by
its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile.
Coupons shall bear the facsimile signature of the Chairman of the Board, President, Treasurer or any Vice President of the Company.


 


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 as in this Indenture provided
and not otherwise.


 




    	 	-19-	 



     


    

 


If the form or terms
of the Securities of the series have been established in or pursuant to one or more Board Resolutions or Officer’s Certificate
as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities, the Trustee shall be given (in addition to the other documents required by Section 103
hereof), and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,


 


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


 


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


 


(c)          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 legal, valid and binding obligations of the Company, enforceable in accordance
with their terms, except as such enforcement is subject to the effect of bankruptcy, insolvency, fraudulent conveyance, reorganization
or other laws relating to or affecting creditors’ rights, and general principles of equity (regardless of whether such enforcement
is considered in a proceeding in equity or at law); provided that such Opinion of Counsel need express no opinion as to
whether a court in the United States would render a money judgment in currency other than that of the United States.


 


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 not
reasonably acceptable to the Trustee.


 


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 309 together with a written statement (which need not comply with Section 103 and need not be accompanied by an Opinion
of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.


 


SECTION
304.        TEMPORARY SECURITIES.


 


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


 




    	 	-20-	 



     


    

 


Except in the case of
temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall
be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office
or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations. 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.


 


All Outstanding temporary
Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of
the same series and of like tenor authenticated and delivered hereunder.


 


SECTION
305.        REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.


 


The Company shall cause
to be kept for each series of Securities at one of the offices or agencies maintained pursuant to Section 1002 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 Registered Securities and of transfers of Registered Securities of such series.
The Trustee is hereby initially appointed “Security Registrar” for the purpose of registering Securities and transfers
of Securities as herein provided.


 


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


 


At the option of the
Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series and of like tenor,
of any authorized denominations and of a like 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.


 




    	 	-21-	 



     


    

 


Notwithstanding the foregoing,
except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided
in this paragraph. If the beneficial owners of interests in a permanent global Security are entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified
as contemplated by Section 301, then without unnecessary delay but in any event not later than the earliest date on which such
interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities of that series in an aggregate principal
amount equal to the principal amount of such permanent global Security, executed by the Company. On or after the earliest date
on which such interests may be so exchanged, such permanent global Security shall be surrendered from time to time in accordance
with instructions given to the Trustee and the Depositary (which instructions shall be in writing but need not comply with Section
103 or be accompanied by an Opinion of Counsel) or such other depositary as shall be specified in the Company Order with respect
thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities
of the same series without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent
global Security, a like aggregate principal amount of other definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such permanent global Security to be exchanged; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of that series
is to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such permanent global
Security marked to evidence the partial exchange shall be returned by the Trustee to the Depositary or such other depositary referred
to above in accordance with the instructions of the Company referred to above. If a Registered Security is issued in exchange for
any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i)
any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of
Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date
or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent
global Security is payable in accordance with the provisions of this Indenture.


 


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


 


Every Registered Security
presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the 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 his attorney duly authorized in writing.


 


No service charge shall
be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchange pursuant to Section 304, 905 or 1107 not involving any transfer.


 


The Company shall not
be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of Securities of such series selected for redemption
and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer
of or exchange any Registered Security so selected for redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.


 


SECTION
306.        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.


 




    	 	-22-	 



     


    

 


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 upon its request 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 fee 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
307.        PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.


 


Interest on any Registered
Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record
Date for such interest. Unless otherwise provided with respect to the Securities of any series, payment of interest may be made
at the option of the Company by check mailed or delivered to the address of any Person entitled thereto as such address shall appear
in the Security Register.


 


Any interest on any Registered
Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (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:


 




    	 	-23-	 



     


    

 


(1)         The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money 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 mailed, first-class postage prepaid, to each Holder of Registered Securities of such
series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. The Trustee
may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in
an Authorized Newspaper, but such publication shall not be a condition precedent to the establishment of such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted
Interest shall be paid to the Persons in whose names the Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the
following clause (2).


 


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


 


Subject to the foregoing
provisions of this Section, each Security delivered under this Indenture, upon registration of transfer of, in exchange for or
in lieu of, any other Security, shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.


 


SECTION
308.        PERSONS DEEMED OWNERS.


 


Prior to due presentment
of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose
of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Registered 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
309.        CANCELLATION.


 


All Securities surrendered
for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered
to any Person other than the Trustee, be delivered to the Trustee. All Registered Securities so delivered shall be promptly cancelled
by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed
of in its customary manner.

SECTION
310.        COMPUTATION OF INTEREST.


 


Except as otherwise specified
as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the
basis of a year comprising twelve 30-day months.


 


SECTION
311.        CUSIP NUMBERS.


 


The Company in issuing
the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP”
numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation
is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption
and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers.

of registration of transfer, exchange or replacement of such series of Securities herein expressly provided for), and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with
respect to such Securities, when


 


(1)         either


 


(A)         all
such Securities of such series theretofore authenticated and delivered (other than (i) such Securities which have been destroyed,
lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) such Securities of such series for whose

and the Company, in the case
of (B)(i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee, as funds in trust for such purpose, an
amount in the currency or currencies or currency unit or units in which such Securities of such series are payable or U.S. Government

be sufficient to pay and discharge the entire indebtedness on such Securities of such series not theretofore delivered to the Trustee
for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have
become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

of the Company to the Trustee under Section 607 and to any Authenticating Agent under Section 614 and, if money or U.S. Government
Obligations shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section, the obligations
of the Trustee under Section 406, Article VI and the last paragraph of Section 1003 shall survive such satisfaction and discharge.


 


SECTION
402.        OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.


 


In addition to the Company’s
rights under Section 401 (which shall not be affected by this Section 402), the Company may, at the option of its Board of Directors
evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 403 or 404 hereof
applied to all Outstanding Securities of any series upon compliance with the conditions set forth in Sections 403 through 406 hereof.


 


SECTION
403.        LEGAL DEFEASANCE AND DISCHARGE.


 


Upon the Company’s
exercise under Section 402 hereof of the option applicable to this Section 403, the Company and the Guarantors shall, subject to
the satisfaction of the conditions set forth in Section 405 hereof, be deemed to have been discharged from their obligations with
respect to all Outstanding Securities of a series on the date the conditions set forth below are satisfied (hereinafter, “Legal
Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Securities of a series, which shall thereafter be deemed to be “outstanding”
only for the purposes of Section 406 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Securities and this Indenture (and the Trustee, on demand of and at the expense
of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of Outstanding Securities of any series to receive
payments in respect of the principal of, premium, if any, and interest, if any, on such Securities when such payments are due from
the trust referred to in Section 405, (b) the Company’s obligations with respect to such Securities under Sections 304, 305,
306 and 1002 of this Indenture, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s
obligations in connection therewith and (d) this Article IV. Subject to compliance with Sections 402 through 406 hereof, the Company
may exercise its option under this Section 403 notwithstanding the prior exercise of its option under Section 404 hereof.

SECTION
404.        COVENANT DEFEASANCE.


 


Upon the Company’s
exercise under Section 402 hereof of the option applicable to this Section 404, the Company shall, subject to the satisfaction
of the conditions set forth in Section 405 hereof, be released from the operation of Section 801 hereof with respect to the Outstanding
Securities of a series and any other covenant contained in the Board Resolution or supplemental indenture relating to such series
on and after the date the conditions set forth in Section 405 are satisfied (hereinafter, “Covenant Defeasance”), and
the Securities of such series shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver,
consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue
to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be
deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the Outstanding
Securities of such series, the Company may omit to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission
to comply shall not constitute a Default or an Event of Default under Section 501 hereof, but, except as specified above, the remainder
of this Indenture and such series of Securities shall be unaffected thereby. In addition, upon the Company’s exercise under
Section 402 hereof of the option applicable to this Section 404 hereof, subject to the satisfaction of the conditions set forth
in Section 405 hereof, Sections 501(3) through 501(6) and Section 501(9) hereof shall not constitute Events of Default.


 


SECTION
405.        CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.


 


The following shall be
the conditions to the application of either Section 403 or 404 hereof to the Outstanding Securities of any series:


 


In order to exercise
either Legal Defeasance or Covenant Defeasance:


 


(a)          the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Securities, cash in United States
dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, to pay the principal of,
or interest and premium, if any, on the Outstanding Securities of such series on the Stated Maturity or on the applicable redemption
date, as the case may be, and the Company must specify whether the Securities are being defeased to maturity or to a particular
redemption date;


 


(b)          in
the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
Trustee confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling
or (ii) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the Outstanding Securities of such series
will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject
to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance
had not occurred;


 


(c)          in
the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to
the Trustee confirming that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for
federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;


 




    	 	-27-	 



     


    

 


(d)          no
Default or Event of Default shall have occurred and be continuing either: (i) on the date of such deposit (other than a Default
or Event of Default resulting from the borrowing of funds to be applied to such deposit); or (ii) insofar as Events of Default
from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;


 


(e)          such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material
agreement or instrument (other than this Indenture) to which the Company is a party or by which the Company is bound;


 


(f)          the
Company must have delivered to the Trustee an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of the
Company or any Guarantor between the date of deposit and the 91st day following the deposit and assuming that no Holder is an “insider”
of the Company under applicable bankruptcy law, after the 91st day following the deposit, the trust funds will not be subject to
the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;


 


(g)          the
Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Securities over the other creditors of the Company with the intent of defeating, hindering,
delaying or defrauding creditors of the Company or others; and


 


(h)          the
Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.


 


SECTION
406.        DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST; OTHER
MISCELLANEOUS PROVISIONS.


 


Subject to Section 407
hereof, all money and non callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 406, the “Trustee”) pursuant to Section 401 or
404 hereof in respect of the Outstanding Securities of any series shall be held in trust and applied by the Trustee, in accordance
with the provisions of such Securities and this Indenture, to the payment, either directly or through any paying agent (including
the Company acting as paying agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become
due thereon in respect of principal, premium on , if any, and interest, but such money need not be segregated from other funds
except to the extent required by law.


 


The Company shall pay
and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government
Obligations deposited pursuant to Section 401 or 404 hereof or the principal and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities.


 


Anything in this Article
IV to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the written request
of the Company any money or non-callable U.S. Government Obligations held by it as provided in Section 401 or 404 hereof which,
in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered
to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance
or Covenant Defeasance or satisfaction and discharge of this Indenture.

SECTION
407.        REPAYMENT TO COMPANY.


 


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, premium on, if any,
or interest on any Securities and remaining unclaimed for two years after such principal, and premium, if any, or interest has
become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Securities shall thereafter, as an unsecured 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 the New York Times and The
Wall Street Journal (national edition), 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 notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.


 


SECTION
408.        REINSTATEMENT.


 


If the Trustee or Paying
Agent is unable to apply any money or U.S. Government Obligations deposited with respect to Securities of any series in accordance
with Section 401, 403 or 404 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture with
respect to the Securities of such series and the Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to Section 401, 403 or 404 hereof until such time as the Trustee or Paying Agent is permitted to apply all
such money or U.S. Government Obligations in accordance with Section 401, 403 or 404 hereof, as the case may be; provided,
however, that, if the Company makes any payment of principal of, premium on, if any, or interest on any Securities following
the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive
such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

A Default under clause
(3) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the Securities of the applicable series notify the Company and the Trustee of the Default and (except in the case of a default
with respect to any provisions of any supplemental indenture or Board Resolution establishing such series of Securities giving
the Holders of Securities of such series the right to require the Company to repurchase or redeem such Securities of such series
upon the occurrence of a change of control prior to the final maturity date of such Securities of such series (“Change of
Control Provisions”) or Article VIII (or any replacement provisions contemplated by Article VIII)) the Company does not cure
the Default within 90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state
that the notice is a “Notice of Default.”


 


SECTION
502.        ACCELERATION.


 


If any Event of Default
(other than an Event of Default specified in clause (7) or (8) of Section 501 hereof) with respect to Securities of any series
occurs and is continuing, either the Trustee or the Holders of at least 25% in principal amount of the then Outstanding Securities
of that series may declare all the Securities of that series to be due and payable immediately. Upon any such declaration, the
Securities of that series shall become due and payable immediately, by a notice in writing to the Company (and to the Trustee if
given by Holders). Notwithstanding the foregoing, if an Event of Default specified in clause (7) or (8) of Section 501 hereof occurs
with respect to any series of Securities, all outstanding Securities of that series shall become due and payable without further
action or notice. The Holders of a majority in aggregate principal amount of Securities of any series then Outstanding by notice
to the Trustee may on behalf of the Holders of all of the Securities of that series waive any existing Default or Event of Default
and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium,
if any, on, or the principal of, the Securities of that series.


 


SECTION
503.        OTHER REMEDIES.


 


If an Event of Default
with respect to Securities of any series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment
of principal, premium, if any, and interest on the Securities of that series or to enforce the performance of any provision of
the Securities of that series or this Indenture.


 


The Trustee may maintain
a proceeding even if it does not possess any of the Securities in a series or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder of a Security in exercising any right or remedy accruing upon an Event of Default
shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative
to the extent permitted by law.


 


SECTION
504.        WAIVER OF PAST DEFAULTS.


 


Holders of not less than
a majority in aggregate principal amount of the then outstanding Securities in any series by notice to the Trustee may on behalf
of the Holders of all of the Securities of that series waive any existing Default or Event of Default and its consequences hereunder,
except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Securities
of that series (including in connection with an offer to purchase) (provided, however, that the Holders of a majority
in aggregate principal amount of the then outstanding Securities of any series may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration, with respect to that series). Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.


 




    	 	-31-	 



     


    

 


SECTION
505.        CONTROL BY MAJORITY.


 


With respect to any series
of Securities, Holders of a majority in principal amount of the then outstanding Securities of that series may direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee
determines may be unduly prejudicial to the rights of other Holders of Securities of any series or that may involve the Trustee
in personal liability.


 


SECTION
506.        LIMITATION ON SUITS.


 


A Holder of a Security
of any series may pursue a remedy with respect to this Indenture or the Securities of that series only if:


 


(a)          the
Holder of a Security of that series gives to the Trustee written notice of a continuing Event of Default;


 


(b)          the
Holders of at least 25% in principal amount of the then outstanding Securities of that series make a written request to the Trustee
to pursue the remedy;


 


(c)          such
Holder of a Security or Holders of Securities offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense;


 


(d)          the
Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision
of indemnity; and


 


(e)          during
such 60-day period the Holders of a majority in principal amount of the then outstanding Securities of that series do not give
the Trustee a direction inconsistent with the request.


 


A Holder of a Security
may not use this Indenture to prejudice the rights of another Holder of a Security or to obtain a preference or priority over another
Holder of a Security.


 


SECTION
507.        RIGHTS OF HOLDERS OF SECURITIES TO RECEIVE PAYMENT.


 


Notwithstanding any other
provision of this Indenture, the right of any Holder of a Security of any series to receive payment of principal, premium, if any,
and interest on the Security, on or after the respective due dates expressed in the Security (including in connection with an offer
to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder.


 


SECTION
508.        COLLECTION SUIT BY TRUSTEE.


 


With respect to the Securities
of any series, if an Event of Default specified in clause (1) or (2) of Section 501 hereof occurs and is continuing, the Trustee
is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of
principal of, premium on, if any, and interest remaining unpaid on the Securities of that series and interest on overdue principal
and, to the extent lawful, interest and 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.

SECTION
509.        TRUSTEE MAY
FILE PROOFS OF CLAIM.


 


The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Securities of any series allowed in any judicial proceedings relative to the Company (or any other
obligor upon the Securities), its creditors or its property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder of that series to make such payments to the Trustee, and in the event that the Trustee shall consent
to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section
607 of this Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section 607 of this Indenture out of the estate in any such
proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and
all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed
to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of any series of Securities any
plan of reorganization, arrangement, adjustment or composition affecting the Securities of that series or the rights of any Holder,
or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.


 


SECTION
510.        PRIORITIES.


 


If the Trustee collects
any money pursuant to this Article, it shall pay out the money in the following order:


 


(a)          First:
to the Trustee, its agents and attorneys for amounts due under Section 607 of this Indenture, including payment of all compensation,
expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any,
and interest, respectively; and


 


(c)          Third:
to the Company or to such party as a court of competent jurisdiction shall direct.

SECTION
511.        UNDERTAKING FOR COSTS.


 


In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee,
a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit,

party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a Security pursuant to Section 507 hereof, or a suit
by Holders of more than 10% in principal amount of the then outstanding Securities of any series.

Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and


 


(2)         in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but in the case of any such certificates or opinions that by any provision hereof are specifically required to
be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether they conform to the requirements
of this Indenture (but need not confirm or investigate the accuracy of mathematical calculation or other facts stated therein).


 


(b)          In
case an Event of Default has occurred and is continuing with respect to the Securities of any series, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.


 


(c)          No
provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent

provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability

grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured
to it.

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.

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.


 


(e)          If

cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor

SECTION
611.        ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.


 


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

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.


 


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

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
612.        MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.


 


Any corporation into
which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of
the parties hereto; provided, however, that in the case of a corporation succeeding to all or substantially all the
corporate trust business of the Trustee, such successor corporation shall expressly assume all of the Trustee’s liabilities
hereunder. 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.


 


SECTION
613.        PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.


 


The Trustee shall comply
with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture
Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated
therein.


 


SECTION
614.        APPOINTMENT OF AUTHENTICATING AGENT.


 


The Trustee may appoint
an Authenticating Agent or Agents that shall be authorized to act on behalf of the Trustee to authenticate Securities issued upon
original issue and upon exchange, registration of transfer or partial redemption or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery
on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and 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 having a combined
capital and surplus of not less than $50 million or equivalent amount expressed in a foreign currency and subject to supervision
or examination by Federal or State (or the District of Columbia) authority or authority of such country. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section 614, the combined capital and surplus of such Authenticating Agent shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section 614, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 614.


 


Any corporation into
which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided
such corporation shall be otherwise eligible under this Section 614, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.


 




    	 	-41-	 



     


    

 


An Authenticating Agent
may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section 614, the Trustee may appoint a successor Authenticating Agent which shall be
acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders
as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of
this Section 614.


 


The Trustee agrees to
pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 614, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.


 


If an appointment is
made pursuant to this Section 614, the Securities may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternate certificate of authentication in the following form:


 


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


 


	 	 	 
	 	 	AS TRUSTEE
	 	 	 
	 	By	 
	 	 	AS AUTHENTICATING AGENT
	 	 	 
	 	By	 
	 	 	AS AUTHORIZED SIGNATORY”


 


Notwithstanding any provision
of this Section 614 to the contrary, if at any time any Authenticating Agent appointed hereunder with respect to any series of
Securities shall not also be acting as the Security Registrar hereunder with respect to any series of Securities, then, in addition
to all other duties of an Authenticating Agent hereunder, such Authenticating Agent shall also be obligated (i) to furnish to the
Security Registrar promptly all information necessary to enable the Security Registrar to maintain at all times an accurate and
current Security Register and (ii) prior to authenticating any Security denominated in a foreign currency, to ascertain from the
Company the units of such foreign currency that are required to be determined by the Company pursuant to Section 302.

the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment,
transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the
“Company” shall refer instead to the successor corporation and not to the Company), and may exercise every right and
power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of
and interest on the Securities except in the case of a sale of all of the Company’s assets that meets the requirements of
Section 801 hereof.

SECTION

Notwithstanding Section

the consent of any Holder of a Security of any series:


 


(a)          to
cure any ambiguity, defect or inconsistency;


 


(b)          to
provide for uncertificated Securities in addition to or in place of certificated Securities or to alter the provisions of Article

to the Company pursuant to Article VIII of this Indenture;


 


(e)          to
make any change that would provide any additional rights or benefits to the Holders of the Securities or that does not adversely
affect the legal rights hereunder of any such Holder;


 


(f)          to
comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture
Act;


 


(g)          to
evidence and provide the acceptance of the appointment of a successor Trustee pursuant to Sections 610 and 611 of this Indenture;
and


 




    	 	-45-	 



     


    

 


(h)          to
add a Guarantor of the Securities.


 


Upon the request of the
Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture,
and upon receipt by the Trustee of the documents described in Section 603 of this Indenture, the Trustee shall join with the Company
in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any
further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter
into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.


 


SECTION
902.        WITH CONSENT OF HOLDERS.


 


Except as provided below
in this Section 902, the Company and the Trustee may amend or supplement this Indenture and the Securities of any series may be
amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount at maturity of Securities
of that series then Outstanding voting as a single class (including, without limitation, consents obtained in connection with a
purchase of, or tender offer or exchange offer for, that series of Securities), and, subject to Sections 504 and 507 hereof, any
existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if
any, and interest, if any, on such Securities, except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture or such Securities may be waived with the consent of the Holders of a majority
in aggregate principal amount at maturity of the then Outstanding Securities of that series voting as a single class (including
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, that series of Securities).


 


Upon the request of the
Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of that series of Securities as aforesaid,
and upon receipt by the Trustee of the documents described in Section 603 of this Indenture, the Trustee shall join with the Company
in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall
not be obligated to, enter into such amended or supplemental indenture.


 


It shall not be necessary
for the consent of the Holders of Securities under this Section 902 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance thereof.


 


After an amendment, supplement
or waiver under this Section becomes effective, the Company shall mail to the Holders of Securities of any series affected thereby
a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.


 


Subject to Sections 504
and 507 hereof, the Holders of a majority in aggregate principal amount at maturity of a series of Securities then Outstanding
voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the
Securities. However, without the consent of each Holder of a series of Securities affected, an amendment or waiver under this Section
902 may not (with respect to the series of Securities held by a non-consenting Holder):


 




    	 	-46-	 



     


    

 


(a)          reduce
the principal amount of the then Outstanding Securities whose Holders must consent to an amendment, supplement or waiver;


 


(b)          reduce
the principal of or change the fixed maturity of any Security or alter any of the provisions with respect to the redemption of
the Securities unless otherwise specifically provided for in the supplemental indenture;


 


(c)          reduce
the rate of or change the time for payment of interest on any Security;


 


(d)          waive
a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Securities (except a rescission
of acceleration of the Securities by the Holders of any series of Securities of at least a majority in aggregate principal amount
of the then Outstanding Securities of that series and a waiver of the payment default that resulted from such acceleration);


 


(e)          make
any Security payable in money other than that stated in the Security;


 


(f)          make
any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Securities to receive
payments of principal of, or interest or premium, if any, on the Securities;


 


(g)          waive
a redemption payment with respect to any Security (other than as may be specifically permitted by the supplemental indenture);


 


(h)          cause
the Securities to become subordinated in right of payment to any other Indebtedness;


 


(i)          release
any Guarantor from any of its obligations under its Guarantee or this Indenture, except in accordance with the terms thereof; or


 


(j)          make
any change in Sections 504 or 507 or the foregoing amendment and waiver provisions.


 


SECTION 903.        COMPLIANCE
WITH TRUST INDENTURE ACT.


 


Every amendment or supplement
to this Indenture or the Securities shall be set forth in a amended or supplemental indenture that complies with the Trust Indenture
Act as then in effect.


 


SECTION 904.        REVOCATION
AND EFFECT OF CONSENTS.


 


Until an amendment, supplement
or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder of a Security and
every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security,
even if notation of the consent is not made on any Security. However, any such Holder of a Security or subsequent Holder of a Security
may revoke the consent as to its Security if the Trustee receives written notice of revocation before the date the waiver, supplement
or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter
binds every Holder.

SECTION
905.        NOTATION ON OR EXCHANGE OF SECURITIES.


 


The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Security thereafter authenticated. The Company in exchange
for all Securities of a series may issue and the Trustee shall, upon receipt of a written order from the Company to authenticate
such Securities, authenticate new Securities that reflect the amendment, supplement or waiver.


 


SECTION
906.        TRUSTEE TO
SIGN AMENDMENTS, ETC.


 


The Trustee shall sign
any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture
until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be given and (subject
to Section 601 of this Indenture) shall be fully protected in relying upon, in addition to the documents required by Section 603
this Indenture, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

COVENANTS


 


SECTION
1001.        PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.


 


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


 


SECTION
1002.        MAINTENANCE OF OFFICE OR AGENCY.


 


If Securities of a series
are issuable only as Registered Securities, the Company will maintain in each Place of Payment for any series of Securities an
office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may
be surrendered for registration of transfer or exchange 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.


 


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
1003.        MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.


 


If the Company shall
at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal
of (and premium, if any) or interest on or any Additional Amounts with respect to 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 premium, if any) or
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, the Company will, on or before each due date of the principal
of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled
to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee
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)         hold
all sums held by it for the payment of the principal of (and premium, if any), interest on or any Additional Amounts with respect
to Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons
or otherwise disposed of as herein provided;


 


(2)         give
the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any
payment of principal (and premium, if any), interest on or any Additional Amounts with respect to the Securities of that series;
and


 


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


 


The Company may at any
time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be
held by the Trustee upon the same trusts as those upon which sums were held by the Company or such Paying Agent; and, upon such
payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such
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 (and premium, if any)
or interest on any Security of any series and remaining unclaimed for three years after such principal (and premium, if any) or
interest has become due and payable shall, unless otherwise required by mandatory provisions of applicable escheat, or abandoned
or unclaimed property law, 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 an Authorized Newspaper in
the Borough of Manhattan, the City of New York and in such other Authorized Newspapers as the Trustee shall deem appropriate, notice
that such money remains unclaimed and that, after a date specified herein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will, unless otherwise required by mandatory provisions of
applicable escheat, or abandoned or unclaimed property law, be repaid to the Company.

SECTION
1004.        EXISTENCE.


 


Subject to Article VIII,
the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.


 


SECTION
1005.        STATEMENT BY OFFICERS AS TO DEFAULT.


 


The Company shall deliver
to the Trustee, within 120 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing
officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this
Indenture, and further stating, as to each such officer signing such certificate, that to the best of his or such Officer’s
knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not
in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default
or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge
and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no
event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on
the Securities is prohibited or if such event has occurred, a description of the event and what action the Company is taking or
proposes to take with respect thereto.


 


The Company shall, so
long as any of the Securities are outstanding, deliver to the Trustee, forthwith and in any event within five days upon any officer
becoming aware of any Default or Event of Default or an event which, with notice or the lapse of time or both, would constitute
an Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is
taking or proposes to take with respect thereto.


 


SECTION
1006.        WAIVER OF CERTAIN COVENANTS.


 


The Company may omit
in any particular instance to comply with any covenant or condition set forth in Section 1005, or any covenant added for the benefit
of any series of Securities as contemplated by Section 301 (unless otherwise specified pursuant to Section 301) if before or after
the time for such compliance the Holders of a majority in principal amount of the Outstanding Securities of all series affected
by such omission (acting as one class) shall, by Act of such Holders, either waive such compliance in such instance or generally
waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant 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 covenant or condition shall remain in full force and effect.


 


SECTION
1007.        ADDITIONAL AMOUNTS.


 


If the Securities of
a series expressly provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series
Additional Amounts as expressly provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received from
the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional
Amounts provided for in this Section 1007 to the extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to the provisions of this Section 1007 and express mention of the payment of Additional Amounts (if
applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.


 




    	 	-50-	 



     


    

 


If the Securities of
a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which
a payment of principal and any premium is made), and at least 10 days prior to each date of payment of principal and any premium
or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate,
the Company shall furnish the Trustee and the Company’s principal Paying Agent or Paying Agents, if other than the Trustee,
with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal
of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series who are United
States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities
of that series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount,
if any, required to be withheld on such payments to such Holders of Securities and the Company will pay to such Paying Agent the
Additional Amounts required by this Section. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold
them harmless against any loss, liability or expense reasonably incurred without negligence or willful misconduct on their part
arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished
pursuant to this Section 1007.

SECTION
1102.        ELECTION TO REDEEM; NOTICE TO TRUSTEE.


 


The election of the Company

less than all the Securities of any series, the Company shall, a reasonable period prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal
amount of Securities of such series to be redeemed. 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
1103.        SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.


 


If less than all the

to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and that may provide for the selection for redemption of portions (equal

of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series or

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


 


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


 


SECTION
1104.        NOTICE OF REDEMPTION.

(4)         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,


 


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


 


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


 


(7)         the
“CUSIP” number, if applicable.


 


A notice of redemption
as contemplated by Section 107 need not identify particular Registered Securities to be redeemed. Notice of redemption of Securities
to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request and provision to
the Trustee of the notice information 10 days prior to delivery of the notice, by the Trustee in the name and at the expense of
the Company.

1105.        DEPOSIT OF REDEMPTION PRICE.


 


On or before 10:00 a.m.,
New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company

the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on and any Additional

Notice of redemption
having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance
with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest (and any Additional
Amounts) to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered
as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.


 


If any Security called
for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the Security or, in the case of Original Issue Discount
Securities, the Securities’ Yield to Maturity.


 


SECTION
1107.        SECURITIES REDEEMED IN PART.

by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series and
Stated Maturity, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.


 


SECTION
1108.        PURCHASE OF SECURITIES.


 


Unless otherwise specified
as contemplated by Section 301, the Company and any Affiliate of the Company may at any time purchase or otherwise acquire Securities
in the open market or by private agreement. Such acquisition shall not operate as or be deemed for any purpose to be a redemption
of the indebtedness represented by such Securities. Any Securities purchased or acquired by the Company may be delivered to the
Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 309 shall apply
to all Securities so delivered.

the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the

(a)          The
holding of Securities shall be proved in the manner specified in Section 105 and the appointment of any proxy shall be proved in

as contemplated by Section 301 hereof) of the Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and
ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or as a proxy.
