Section 1.05.     
Acts of Holders; Record Dates.


 


(1)         Any 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 6.01) 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 13.06.


 


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 1.06 and to the relevant Holders
as set forth in Section 1.07.


 


(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.


 






    	 	11	 



     


    

 


(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 1.06.     
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.

provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

Section 1.07.     
Notice to Holders; Waiver.


 


Where this Indenture provides for notice to Holders
of Securities of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the address of such 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.


 


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 1.08.     
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.

or implied, shall give to any Person, other than the parties hereto and their successors hereunder, any Authenticating Agent, Paying Agent

by and construed in accordance with the laws of the State of New York, but without giving effect to applicable principles of conflicts

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
3.03 for the authentication and delivery of such Securities (or any such temporary global Security).

Section 2.03.     
Securities in Global Form.


 


If Securities of a series are issuable in global
form, as contemplated by Section 3.01, then, notwithstanding clause (10) of Section 3.01 and the provisions of Section 3.02, 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 3.03 or Section 3.04. Subject to the provisions of Section 3.03 and, if applicable, Section
3.04, 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 3.03 or 3.04 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 1.03 and need not be accompanied by an Opinion of Counsel.


 


The provisions of the last sentence of Section 3.03
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 1.03 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 3.03.


 


Notwithstanding the provisions of Sections 2.01 and
3.07, unless otherwise specified as contemplated by Section 3.01, 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 3.08 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 2.04.     
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 3.03, 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):


 






    	 	16	 



     


    

 


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 3.03. 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.


 


(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.


 






    	 	17	 



     


    

 


Upon any exchange of Book-Entry Securities for Registered
Securities not issued in global form as set forth in this Section 2.04(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

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.

premium, if any) and interest on such Book-Entry Security and redemption thereof and all notices with respect to such Book-Entry Security
shall be made and given, respectively, in the manner provided in the arrangements of the Company with such Depositary.

    	 	20	 



     


    

 


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 3.03) 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 3.02.     
Denominations.


 


The Securities of each series shall be issuable in
such denominations as shall be specified as contemplated by Section 3.01. 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 any multiple of $1,000.
Unless otherwise provided as contemplated by Section 3.01 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 any multiple of $1,000.


 


Section 3.03.     
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.


 






    	 	21	 



     


    

 


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.


 


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 2.01 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 1.03 hereof), and (subject to Section 6.01) 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 2.01, 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 3.01, 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 3.09 together with a written statement (which need not comply
with Section 1.03 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.


 






    	 	22	 



     


    

 


Section 3.04.     
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.


 


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 3.05.     
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 10.02 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.


 






    	 	23	 



     


    

 


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.


 


Notwithstanding the foregoing, except as otherwise
specified as contemplated by Section 3.01, 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 3.01, 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 1.03 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.


 






    	 	24	 



     


    

 


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 3.04, 9.05 or 11.07 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 3.06.     
Mutilated, Destroyed, Lost and Stolen Securities.


 


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


 


If there shall be delivered to the Company and the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may
be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and 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.


 






    	 	25	 



     


    

 


Every new Security of any series issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the
Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.


 


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


 


Section 3.07.     
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:


 


(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).


 






    	 	26	 



     


    

 


(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 3.08.     
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 3.05 and 3.07) 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 3.09.     
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 3.10.     
Computation of Interest.


 


Except as otherwise specified as contemplated by
Section 3.01 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 3.11.     
CUSIP Numbers.


 






    	 	27	 



     


    

 


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.

precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series of Securities have
been complied with.


 


Notwithstanding the satisfaction and discharge of
this Indenture with respect to the Outstanding Securities of such series pursuant to this Section 4.01, the obligations of the Company
to the Trustee under Section 6.07 and to any Authenticating Agent under Section 6.14 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
4.06, Article VI and the last paragraph of Section 10.03 shall survive such satisfaction and discharge.


 


Section 4.02.     
Option to Effect Legal Defeasance or Covenant Defeasance.


 


In addition to the Company’s rights under Section
4.01 (which shall not be affected by this Section 4.02), 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 4.03 or 4.04 hereof applied to all Outstanding
Securities of any series upon compliance with the conditions set forth in Sections 4.03 through 4.06 hereof.


 


Section 4.03.     
Legal Defeasance and Discharge.


 


Upon the Company’s exercise under Section 4.02
hereof of the option applicable to this Section 4.03, the Company and the Guarantors shall, subject to the satisfaction of the conditions
set forth in Section 4.05 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 4.06 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 4.05, (b) the Company’s obligations
with respect to such Securities under Sections 3.04, 3.05, 3.06 and 10.02 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 4.02 through 4.06 hereof, the Company may exercise its option under this Section 4.03 notwithstanding the prior exercise
of its option under Section 4.04 hereof.


 






    	 	29	 



     


    

 


Section 4.04.     
Covenant Defeasance.


 


Upon the Company’s exercise under Section 4.02
hereof of the option applicable to this Section 4.04, the Company shall, subject to the satisfaction of the conditions set forth in Section
4.05 hereof, be released from the operation of Section 8.01 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 4.05 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 5.01 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 4.02 hereof of the option applicable to this Section 4.04 hereof, subject to the satisfaction of the conditions
set forth in Section 4.05 hereof, Sections 5.01(3) through 5.01(6) and Section 5.01(9) hereof shall not constitute Events of Default.


 


Section 4.05.     
Conditions to Legal or Covenant Defeasance.


 


The following shall be the conditions to the application
of either Section 4.03 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;


 






    	 	30	 



     


    

 





(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;


 


(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 4.06.     
Deposited Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions.


 






    	 	31	 



     


    

 


Subject to Section 4.07 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 4.06, the “Trustee”) pursuant to Section 4.01 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 4.01 or 4.04 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 4.01 or 4.04 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 4.07.     
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 4.08.     
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 4.01, 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 4.01, 4.03 or
4.04 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 4.01, 4.03 or 4.04 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.

REMEDIES


 


Section 5.01.     
Events of Default.


 


An “Event of Default” on a series
occurs if:


 


(1)              
the Company defaults in the payment of interest on any Security of such series when the same becomes due and payable and the Default
continues for a period of 30 days after notice of default;


 


(2)              
the Company defaults in the payment of the principal of any Security of such series when the same becomes due and payable at maturity,
upon redemption or otherwise, and continuance of such default for a period of 30 days after notice of default;


 


(3)              
the Company fails to comply with any of its other agreements in the Securities of such series or this Indenture (as they relate
thereto) and the Default continues for the period and after the notice specified below (except in the case of a default with respect to
any Change of Control Provisions or Article VIII (or any replacement provisions contemplated by Article VIII), which will constitute Events
of Default with notice but without passage of time);


 


(4)              
the acceleration of any Indebtedness of the Company in an amount of $50.0 million or more, individually or in the aggregate, and
such acceleration does not cease to exist, or such Indebtedness is not satisfied, in either case within five days after such acceleration;


 


(5)              
the failure by the Company to make any principal or interest payment in an amount of $50.0 million or more, individually or in
the aggregate, in respect of Indebtedness of the Company within five days of such principal or interest becoming due and payable (after
giving effect to any applicable grace period set forth in the documents governing such Indebtedness);


 


(6)              
a final judgment or judgments in an amount of $50.0 million or more, individually or in the aggregate, for the payment of money
having been entered by a court or courts of competent jurisdiction against the Company and such judgment or judgments is not satisfied,
stayed, annulled or rescinded within 90 days after being entered;


 


(7)              
the Company pursuant to or within the meaning of any Bankruptcy Law:


 






    	 	33	 



     


    

 


(a)              
commences a voluntary case,


 


(b)              
consents to the entry of an order for relief against it in an involuntary case,


 


(c)              
consents to the appointment of a Custodian of it or for all or substantially all of its property, or


 


(d)              
makes a general assignment for the benefit of creditors;


 


(8)              
a court of competent jurisdiction enters into an order or decree under any Bankruptcy Law that:


 


(a)              
is for relief against the Company in an involuntary case,


 


(b)              
appoints a Custodian of the Company or for all or substantially all of its property, or


 


(c)              
orders the liquidation of the Company,


 


and the order or decree remains unstayed and in effect for
60 days; or


 


(9)              
any other Event of Default occurs with respect to Securities of that series as provided in the supplemental indenture or Board
Resolutions establishing such series of Securities.


 


The term “Bankruptcy Law” means
the Bankruptcy Act or any similar Federal or State law for the relief of debtors. The term “Custodian” means any receiver,
trustee, assignee, liquidator or similar official under any Bankruptcy Law.


 


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 5.02.     
Acceleration.


 


If any Event of Default (other than an Event of Default
specified in clause (7) or (8) of Section 5.01 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 5.01 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.


 



    	 	34	 



     


    




Section 5.03.     
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 5.04.     
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.


 


Section 5.05.     
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.


 






    	 	35	 



     


    

 


Section 5.06.     
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 5.07.     
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 5.08.     
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 5.01 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.


 



    	 	36	 



     


    

 





Section 5.09.     
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 6.07 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 6.07 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 5.10.     
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 6.07 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;


 


(b)              
Second: to Holders of Securities for amounts due and unpaid on the Securities for principal, premium, if any, and interest, ratably,
without 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.


 


The Trustee may fix a record date and payment date
for any payment to Holders of Securities pursuant to this Section 5.10.


 


Section 5.11.     
Undertaking for Costs.


 






    	 	37	 



     


    

 


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, and the court in its discretion
may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any 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 5.07 hereof, or a suit by Holders of more than 10% in principal amount of
the then outstanding Securities of any series.


 


Article
VI

THE TRUSTEE


 


Section 6.01.     
Certain Duties and Responsibilities.


 


(a)              
Except during the continuance of an Event of Default with respect to the Securities of any series:


 


(1)              
the 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
failure to act or its own willful misconduct, except that:


 


(3)              
this Subsection shall not be construed to limit the effect of Subsection (a) of this Section;


 


(4)              
the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved
that the Trustee was negligent in ascertaining the pertinent facts;


 






    	 	38	 



     


    

 


(5)              
the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with the direction
of the Holders of a majority in principal amount of the Outstanding Securities of any series or of all series, determined as provided
in Section 5.05, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and


 


(6)              
no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it.


 


(d)

The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the resigning

of rehabilitation, conservation or liquidation,


 


then, in any such case, (i) the Company by a Board Resolution may remove
the Trustee with respect to all Securities, or (ii) subject to Section 5.05, any Holder who has been a bona fide Holder of a Security
for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.


 


(e)

any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be
appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with

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

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.

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 6.13.     
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

Section 6.14.     
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 3.06, 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 6.14, 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 6.14, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section 6.14.


 


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 6.14, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating
Agent.


 



    	 	46	 



     


    




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 6.14, 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 6.14.


 


The Trustee agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services under this Section 6.14, and the Trustee shall be entitled to be reimbursed
for such payments, subject to the provisions of Section 6.07.


 


If an appointment is made pursuant to this Section
6.14, 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 6.14
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 3.02.

(ii)             
the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale,

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

SUPPLEMENTAL INDENTURES


 


Section 9.01.     
Without Consent of Holders.


 


Notwithstanding Section 9.02 of this Indenture, the
Company and the Trustee may amend or supplement this Indenture or the Securities of any series without the consent of any Holder of a
Security of any series:


 


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


 






    	 	50	 



     


    

 


(b)              
to provide for uncertificated Securities in addition to or in place of certificated Securities or to alter the provisions of Article
II of this Indenture (including the related definitions) in a manner that does not materially adversely affect any Holder;


 


(c)              
to establish the form or terms of Securities of any series as permitted by Sections 2.01 and 3.01 of this Indenture;


 


(d)              
to provide for the assumption of the Company’s or any Guarantor’s obligations to the Holders of the Securities by a
successor 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 6.10 and 6.11 of this Indenture;
and


 


(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 6.03 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 9.02.     
With Consent of Holders.


 


Except as provided below in this Section 9.02, 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 5.04 and 5.07 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).


 






    	 	51	 



     


    

 


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 6.03 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 9.02 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 5.04 and 5.07 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 9.02 may not (with respect to the series
of Securities held by a non-consenting Holder):


 


(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;


 






    	 	52	 



     


    

 


(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 5.04 or 5.07 or the foregoing amendment and waiver provisions.


 


Section 9.03.     
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 9.04.     
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 9.05.     
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 9.06.     
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 6.01 of this Indenture) shall be
fully protected in relying upon, in addition to the documents required by Section 6.03 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 10.01. 
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 10.02. 
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 10.03. 
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.


 






    	 	54	 



     


    

 


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 10.04. 
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 10.05. 
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 10.06. 
Waiver of Certain Covenants.


 


The Company may omit in any particular instance to
comply with any covenant or condition set forth in Section 10.05, or any covenant added for the benefit of any series of Securities as
contemplated by Section 3.01 (unless otherwise specified pursuant to Section 3.01) 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 10.07. 
Additional Amounts.


 






    	 	56	 



     


    

 


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 10.07 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 10.07
and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not made.


 


If 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 10.07.

3.01 for Securities of any series) in accordance with this Article.


 


Section 11.02. 
Election to Redeem; Notice to Trustee.


 


The election of the Company to redeem any Securities
shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all the Securities of

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.


 






    	 	57	 



     


    

 


Section 11.03. 
Selection by Trustee of Securities to be Redeemed.


 


If less than all the Securities of any series are
to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and
appropriate and that may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities
of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the
minimum authorized denomination for Securities of that series or of the principal amount of global Securities of such series.


 


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 11.04. 
Notice of Redemption.


 


Notice of redemption shall be given in the manner
provided in Section 1.07 to each Holder of Securities to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date.


 


All notices of redemption shall state:


 


(1)              
the Redemption Date,

the Redemption Price,


 


(3)              
if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption,
the principal amounts) of the particular Securities to be redeemed,


 


(4)              
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,


 






    	 	58	 



     


    

 


(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
1.07 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.


 


Section 11.05. 
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 is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if
the Redemption Date shall be an Interest Payment Date) accrued interest on and any Additional Amounts with respect to all the Securities
to be redeemed on that date.


 


Section 11.06. 
Securities Payable on Redemption Date.


 


Notice of redemption having been given as aforesaid,
the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, 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 3.07.


 


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 11.07. 
Securities Redeemed in Part.


 


Any Registered Security which is to be redeemed only
in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or 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 11.08. 
Purchase of Securities.


 


Unless otherwise specified as contemplated by Section
3.01, 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 3.09 shall apply to all Securities so delivered.

respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of
such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited
