Securities of any particular
series may be issued at various times, with different dates on which the principal or any installment of principal is payable, with different
rates of interest, if any, or different methods by which rates of interest may be determined, with different dates on which such interest
may be payable and with different redemption dates.


 


Section 2.02          Form of
Securities and Trustee’s Certificate.


 


The Securities of any series
and the Trustee’s certificate of authentication to be borne by such Securities shall be substantially of the tenor and purport as
set forth in one or more indentures supplemental hereto or as provided in a Board Resolution, and set forth in an Officer’s Certificate,
and they may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed
or engraved thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Indenture, or as may be
required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities
exchange on which Securities of that series may be listed, or to conform to usage.


 


Section 2.03          Denominations:
Provisions for Payment.


 


The Securities shall be issuable
as registered Securities and in the denominations of one thousand U.S. dollars ($1,000) or any integral multiple thereof, subject to Section 2.01(a)(13).
The Securities of a particular series shall bear interest payable on the dates and at the rate specified with respect to that series.
Subject to Section 2.01(a)(23), the principal of and the interest on the Securities of any series, as well as any premium thereon
in case of redemption or repurchase thereof prior to maturity, and any cash amount due upon conversion or exchange thereof, shall be payable
in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or
agency of the Company maintained for that purpose. Each Security shall be dated the date of its authentication. Interest on the Securities
shall be computed on the basis of a 360-day year composed of twelve 30-day months.


 


The interest installment on
any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date for Securities of that series
shall be paid to the Person in whose name said Security (or one or more Predecessor Securities) is registered at the close of business
on the regular record date for such interest installment. In the event that any Security of a particular series or portion thereof is
called for redemption and the redemption date is subsequent to a regular record date with respect to any Interest Payment Date and prior
to such Interest Payment Date, interest on such Security will be paid upon presentation and surrender of such Security as provided in
Section 3.03.


 






    8


     


    

 


Any interest on any Security
that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date for Securities of the same series (herein
called “Defaulted Interest”) shall forthwith cease to be payable to the registered holder on the relevant regular record date
by virtue of having been such holder; and such Defaulted Interest shall be paid by the Company, at its election, as provided in clause
(1) or clause (2) below:


 


(1)            The
Company may make payment of any Defaulted Interest on Securities to the Persons in whose names such Securities (or their respective Predecessor
Securities) are registered in the Security Register 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 such Security and the date of the proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit 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 not be more than 15 nor 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 sent, to each Securityholder not less than 10 days prior
to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been
sent as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Securities (or their respective Predecessor
Securities) are registered in the Security Register on such special record date.


 


(2)            The
Company may make payment of any Defaulted Interest on any Securities 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.


 


Unless otherwise set forth
in a Board Resolution or one or more indentures supplemental hereto establishing the terms of any series of Securities pursuant to Section 2.01
hereof, the term “regular record date” as used in this Section with respect to a series of Securities and any Interest
Payment Date for such series shall mean either the fifteenth day of the month immediately preceding the month in which an Interest Payment
Date established for such series pursuant to Section 2.01 hereof shall occur, if such Interest Payment Date is the first day of a
month, or the first day of the month in which an Interest Payment Date established for such series pursuant to Section 2.01 hereof
shall occur, if such Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day.


 






    9


     


    

 


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


 


Section 2.04          Execution
and Authentications.


 


The Securities shall be signed
on behalf of the Company by one of its Officers. Signatures may be in the form of a manual or facsimile signature.


 


The Company may use the facsimile
signature of any Person who shall have been an Officer (at the time of execution), notwithstanding the fact that at the time the Securities
shall be authenticated and delivered or disposed of such Person shall have ceased to be such an officer of the Company. The Securities
may contain such notations, legends or endorsements required by law, stock exchange rule or usage. Each Security shall be dated the
date of its authentication by the Trustee.


 


A Security shall not be valid
until authenticated manually by an authorized signatory of the Trustee, or by an Authenticating Agent. Such signature shall be conclusive
evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture. 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 written order of the Company for the
authentication and delivery of such Securities, signed by an Officer, and the Trustee in accordance with such written order shall authenticate
and deliver such Securities.


 


Upon
the Company’s delivery of any such authentication order to the Trustee at any time after the initial issuance of Securities under
this Indenture, the Trustee shall be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act)
shall be fully protected in relying upon, (1) an Opinion of Counsel or reliance letter and (2) an Officer’s Certificate
stating that all conditions precedent to the execution, authentication and delivery of such Securities are in conformity with the
provisions of this Indenture.


 


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 that is not reasonably acceptable to the Trustee.


 


Section 2.05          Registration
of Transfer and Exchange.


 


(a)            Securities
of any series may be exchanged upon presentation thereof at the office or agency of the Company designated for such purpose, for other
Securities of such series of authorized denominations, and for a like aggregate principal amount, upon payment of a sum sufficient to
cover any tax or other governmental charge in relation thereto, all as provided in this Section. In respect of any Securities so surrendered
for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the
Security or Securities of the same series that the Securityholder making the exchange shall be entitled to receive, bearing numbers not
contemporaneously outstanding.


 






    10


     


    

 


(b)            The
Company shall keep, or cause to be kept, at its office or agency designated for such purpose a register or registers (herein referred
to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall register
the Securities and the transfers of Securities as in this Article provided and which at all reasonable times shall be open for inspection
by the Trustee. The registrar for the purpose of registering Securities and transfer of Securities as herein provided shall be appointed
as authorized by Board Resolution or Supplemental Indenture (the “Security Registrar”).


 


Upon surrender for transfer
of any Security at the office or agency of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate
and such office or agency shall deliver in the name of the transferee or transferees a new Security or Securities of the same series as
the Security presented for a like aggregate principal amount.


 


The Company initially appoints
the Trustee as Security Registrar for each series of Securities.


 


All Securities presented or
surrendered for exchange or registration of transfer, as provided in this Section, shall be accompanied (if so required by the Company
or the Security Registrar) by a written instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar,
duly executed by the registered holder or by such holder’s duly authorized attorney in writing.


 


(c)            Except
as provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or established
in one or more indentures supplemental to this Indenture, no service charge shall be made for any exchange or registration of transfer
of Securities, or issue of new Securities in case of partial redemption of any series or repurchase, conversion or exchange of less than
the entire principal amount of a Security, but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge in relation thereto, other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04 not involving
any transfer.


 


(d)            The
Company and the Security Registrar shall not be required (i) to issue, exchange or register the transfer of any Securities during
a period beginning at the opening of business 15 days before the day of the sending of a notice of redemption of less than all the Outstanding
Securities of the same series and ending at the close of business on the day of such sending, nor (ii) to register the transfer of
or exchange any Securities of any series or portions thereof called for redemption or surrendered for repurchase, but not validly withdrawn,
other than the unredeemed portion of any such Securities being redeemed in part or not surrendered for repurchase, as the case may be.
The provisions of this Section 2.05 are, with respect to any Global Security, subject to Section 2.11 hereof.


 






    11


     


    

 


The Trustee shall have no
obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or
under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary
participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation
or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine
the same to determine substantial compliance as to form with the express requirements hereof.


 


Section 2.06          Temporary
Securities.


 


Pending the preparation of
definitive Securities of any series, the Company may execute, and the Trustee shall authenticate and deliver, temporary Securities (printed,
lithographed or typewritten) of any authorized denomination. Such temporary Securities shall be substantially in the form of the definitive
Securities in lieu of which they are issued, but with such omissions, insertions and variations as may be appropriate for temporary Securities,
all as may be determined by the Company. Every temporary Security of any series shall be executed by the Company and be authenticated
by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities of such
series. Without unnecessary delay the Company will execute and will furnish definitive Securities of such series and thereupon any or
all temporary Securities of such series may be surrendered in exchange therefor (without charge to the Securityholders), at the office
or agency of the Company designated for the purpose, and the Trustee shall authenticate and such office or agency shall deliver in exchange
for such temporary Securities an equal aggregate principal amount of definitive Securities of such series, unless the Company advises
the Trustee to the effect that definitive Securities need not be executed and furnished until further notice from the Company. Until so
exchanged, the temporary Securities of such series shall be entitled to the same benefits under this Indenture as definitive Securities
of such series authenticated and delivered hereunder.


 


Section 2.07          Mutilated,
Destroyed, Lost or Stolen Securities.


 


In case any temporary or definitive
Security shall become mutilated or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute,
and upon the Company’s request the Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series,
bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution
for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company and
the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss
or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft
of the applicant’s Security and of the ownership thereof. The Trustee may authenticate any such substituted Security and deliver
the same upon the written request or authorization of any officer of the Company. Upon the issuance of any substituted Security, the Company
may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith.


 


In case any Security that
has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute
Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security) if the applicant
for such payment shall furnish to the Company and the Trustee such security or indemnity as they may require to save them harmless, and,
in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of
such Security and of the ownership thereof.


 






    12


     


    

 


Every replacement Security
issued pursuant to the provisions of this Section shall constitute an additional contractual obligation of the Company whether or
not the mutilated, destroyed, lost or stolen Security shall be found at any time, or be enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all other Securities of the same series duly issued hereunder.
All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities, and shall preclude (to the extent lawful) any and all other rights or remedies,
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.


 


Section 2.08          Cancellation.


 


All Securities surrendered
for the purpose of payment, redemption, repurchase, exchange, registration of transfer or conversion shall, if surrendered to the Company
or any paying agent (or any other applicable agent), be delivered to the Trustee for cancellation, or, if surrendered to the Trustee,
shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required or permitted by any of the provisions
of this Indenture. On request of the Company at the time of such surrender, the Trustee shall deliver to the Company canceled Securities
held by the Trustee. In the absence of such request the Trustee may dispose of canceled Securities in accordance with its standard procedures
and deliver a certificate of disposition to the Company. If the Company shall otherwise acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered
to the Trustee for cancellation.


 


Section 2.09          Benefits
of Indenture.


 


Nothing in this Indenture
or in the Securities, express or implied, shall give or be construed to give to any Person, other than the parties hereto and the holders
of the Securities any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition
or provision herein contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the
holders of the Securities.


 


Section 2.10          Authenticating
Agent.


 


So long as any of the Securities
of any series remain Outstanding there may be an Authenticating Agent for any or all such series of Securities which the Trustee shall
have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Securities of
such series issued upon exchange, transfer or partial redemption, repurchase or conversion thereof, 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.
All references in this Indenture to the authentication of Securities by the Trustee shall be deemed to include authentication by an Authenticating
Agent for such series. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital
and surplus, as most recently reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized
or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such business
and is subject to supervision or examination by federal or state authorities. If at any time any Authenticating Agent shall cease to be
eligible in accordance with these provisions, it shall resign immediately.


 






    13


     


    

 


Any Authenticating Agent may
at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time (and upon request
by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating
Agent and to the Company. Upon resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint
an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating
Agent pursuant hereto.


 


Section 2.11          Global
Securities.


 


(a)            If
the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global Security,
then the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver, a Global Security
that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, all of the Outstanding
Securities of such series, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by
the Trustee to the Depositary or pursuant to the Depositary’s instruction (or if the Depositary names the Trustee as its custodian,
retained by the Trustee), and (iv) shall bear a legend substantially to the following effect: “Except as otherwise provided
in Section 2.11 of the Indenture, this Security may be transferred, in whole but not in part, only to another nominee of the Depositary
or to a successor Depositary or to a nominee of such successor Depositary.”


 


(b)            Notwithstanding
the provisions of Section 2.05, the Global Security of a series may be transferred, in whole but not in part and in the manner provided
in Section 2.05, only to another nominee of the Depositary for such series, or to a successor Depositary for such series selected
or approved by the Company or to a nominee of such successor Depositary.


 






    14


     


    

 


(c)            If
at any time the Depositary for a series of the Securities notifies the Company that it is unwilling or unable to continue as Depositary
for such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the Exchange
Act, or other applicable statute or regulation, and a successor Depositary for such series is not appointed by the Company within 90 days
after the Company receives such notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred
and is continuing and the Company has received a request from the Depositary or from the Trustee, this Section 2.11 shall no longer
be applicable to the Securities of such series and the Company will execute, and subject to Section 2.04, the Trustee will authenticate
and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security. In addition,
the Company may at any time determine that the Securities of any series shall no longer be represented by a Global Security and that the
provisions of this Section 2.11 shall no longer apply to the Securities of such series. In such event the Company will execute and,
subject to Section 2.04, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the Company,
will authenticate and deliver the Securities of such series in definitive registered form without coupons, in authorized denominations,
and in an aggregate principal amount equal to the principal amount of the Global Security of such series in exchange for such Global Security.
Upon the exchange of the Global Security for such Securities in definitive registered form without coupons, in authorized denominations,
the Global Security shall be canceled by the Trustee. Such Securities in definitive registered form issued in exchange for the Global
Security pursuant to this Section 2.11(c) shall be registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Securities to the Depositary for delivery to the Persons in whose names such Securities are so registered.







 


Section 2.12          CUSIP
Numbers.


 


The Company in issuing the
Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers
in notices of redemption as a convenience to Securityholders; 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 elements of identification printed on the Securities, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

REDEMPTION
OF SECURITIES AND SINKING FUND PROVISIONS


 


Section 3.01          Redemption.


 


The Company may redeem the
Securities of any series issued hereunder on and after the dates and in accordance with the terms established for such series pursuant
to Section 2.01 hereof.


 






    15


     


    

 


Section 3.02          Notice
of Redemption.


 


(a)            In
case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series in
accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall, or shall cause
the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by mailing (or with regard to
any Global Security held in book entry form, by electronic mail in accordance with the applicable procedures of the Depositary), a notice
of such redemption not less than 30 days and not more than 90 days before the date fixed for redemption of that series to such Securityholders,
unless a shorter period is specified in the Securities to be redeemed. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered holder receives the notice. In any case, failure duly to
give such notice to the holder of any Security of any series designated for redemption in whole or in part, or any defect in the notice,
shall not affect the validity of the proceedings for the redemption of any other Securities of such series or any other series. 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 Officer’s Certificate evidencing compliance with any
such restriction.


 


Each such notice of redemption
shall identify the Securities to be redeemed (including CUSIP numbers, if any), specify the date fixed for redemption and the redemption
price at which Securities of that series are to be redeemed, and shall state that payment of the redemption price of such Securities to
be redeemed will be made at the office or agency of the Company, upon presentation and surrender of such Securities, that interest accrued
to the date fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue
and that the redemption is from a sinking fund, if such is the case. If less than all the Securities of a series are to be redeemed, the
notice to the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be so redeemed.


 


In case any Security is to
be redeemed in part only, the notice that relates to such Security shall state the portion of the principal amount thereof to be redeemed,
and shall state that on and after the redemption date, upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.


 


(b)            If
less than all the Securities of a series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice (unless
a shorter notice shall be satisfactory to the Trustee) in advance of the date fixed for redemption as to the aggregate principal amount
of Securities of the series to be redeemed, and thereupon the Securities to be redeemed shall be selected, by lot, on a pro rata basis,
or in such other manner as the Company shall deem appropriate and fair in its discretion and that may provide for the selection of a portion
or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof) of the principal amount of such Securities
of a denomination larger than $1,000, the Securities to be redeemed and shall thereafter promptly notify the Company in writing of the
numbers of the Securities to be redeemed, in whole or in part. The Company may, if and whenever it shall so elect, by delivery of instructions
signed on its behalf by an Officer, instruct the Trustee or any paying agent to call all or any part of the Securities of a particular
series for redemption and to give notice of redemption in the manner set forth in this Section, such notice to be in the name of the Company
or its own name as the Trustee or such paying agent may deem advisable. In any case in which notice of redemption is to be given by the
Trustee or any such paying agent, the Company shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such
paying agent, as the case may be, such Security Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient
to enable the Trustee or such paying agent to give any notice by mail that may be required under the provisions of this Section.


 






    16


     


    

 


Section 3.03          Payment
Upon Redemption.


 


(a)            If
the giving of notice of redemption shall have been completed as above provided, the Securities or portions of Securities of the series
to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to, but excluding, the date fixed for redemption and interest on such Securities or portions
of Securities shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such
redemption price and accrued interest with respect to any such Security or portion thereof. On presentation and surrender of such Securities
on or after the date fixed for redemption at the place of payment specified in the notice, said Securities shall be paid and redeemed
at the applicable redemption price for such series, together with interest accrued thereon to, but excluding, the date fixed for redemption
(but if the date fixed for redemption is an Interest Payment Date, the interest installment payable on such date shall be payable to the
registered holder at the close of business on the applicable record date pursuant to Section 2.03).


 


(b)            Upon
presentation of any Security of such series that is to be redeemed in part only, the Company shall execute and the Trustee shall authenticate
and the office or agency where the Security is presented shall deliver to the Securityholder thereof, at the expense of the Company, a
new Security of the same series of authorized denominations in principal amount equal to the unredeemed portion of the Security so presented.


 


Section 3.04          Sinking
Fund.


 


The provisions of Sections
3.04, 3.05 and 3.06 shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise specified
as contemplated by Section 2.01 for Securities of such series.


 


The minimum amount of any
sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,”
and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional
sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may
be subject to reduction as provided in Section 3.05. Each sinking fund payment shall be applied to the redemption of Securities of
any series as provided for by the terms of Securities of such series.


 


Section 3.05          Satisfaction
of Sinking Fund Payments with Securities.


 


The Company (i) may deliver
Outstanding Securities of a series and (ii) may apply as a credit Securities of a series that have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant
to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities
of such series required to be made pursuant to the 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 for such purpose by the Trustee at
the redemption price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly.


 






    17


     


    

 


Section 3.06          Redemption
of Securities for Sinking Fund.


 


Not less than 45 days prior
to each sinking fund payment date for any series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Company
will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of the series, the portion thereof, if any, that is to be satisfied by delivering and crediting Securities of that

The Company will duly and
punctually pay or cause to be paid the principal of (and premium, if any) and interest on the Securities of that series at the time and
place and in the manner provided herein and established with respect to such Securities. Payments of principal on the Securities may be

Section 4.02          Maintenance
of Office or Agency.


 


So long as any series of the

payment, (ii) Securities of that series may be presented as herein above authorized for registration of transfer and exchange, and

them. 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, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company
hereby appoints the Trustee as its agent to receive all such presentations, notices and demands. The Company initially appoints the Corporate
Trust Office of the Trustee as its paying agent with respect to the Securities.

Section 4.03          Paying
Agents.


 


(a)            If
the Company shall appoint one or more paying agents for all or any series of the Securities, other than the Trustee, the Company will
cause each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section:


 


(1)            that
it will hold all sums held by it as such agent for the payment of the principal of (and premium, if any) or interest on the Securities
of that series (whether such sums have been paid to it by the Company or by any other obligor of such Securities) in trust for the benefit
of the Persons entitled thereto;


 


(2)            that
it will give the Trustee notice of any failure by the Company (or by any other obligor of such Securities) to make any payment of the
principal of (and premium, if any) or interest on the Securities of that series when the same shall be due and payable;


 


(3)            that
it will, at any time during the continuance of any failure referred to in the preceding paragraph (a)(2) above, upon the written
request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and


 


(4)            that
it will perform all other duties of paying agent as set forth in this Indenture.


 


(b)            If
the Company shall act as its own paying agent with respect to any series of the Securities, it will on or before each due date of the
principal of (and premium, if any) or interest on Securities of that series, set aside, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay such principal (and premium, if any) or interest so becoming due on Securities of
that series until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee
of such action, or any failure (by it or any other obligor on such Securities) to take such action. Whenever the Company shall have one
or more paying agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest
on any Securities of that series, deposit with the 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 this action or failure so to act.


 






    19


     


    

 


(c)            Notwithstanding
anything in this Section to the contrary, (i) the agreement to hold sums in trust as provided in this Section is subject
to the provisions of Section 11.05, and (ii) 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 direct any paying agent to pay, to the Trustee all sums held in trust by
the Company or such paying agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which such sums
were held by the Company or such paying agent; and, upon such payment by the Company or any paying agent to the Trustee, the Company or
such paying agent shall be released from all further liability with respect to such money.

to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so that there

The Company will furnish or
cause to be furnished to the Trustee (a) within 15 days after each regular record date (as defined in Section 2.03) a list,
in such form as the Trustee may reasonably require, of the names and addresses of the holders of each series of Securities as of such
regular record date, provided that the Company shall not be obligated to furnish or cause to furnish such list at any time that the list
shall not differ in any respect from the most recent list furnished to the Trustee by the Company and (b) at such other times as
the Trustee may request in writing within 30 days after the receipt by the Company of any such request, a list of similar form and content
as of a date not more than 15 days prior to the time such list is furnished; provided, however, that, in either case, no such list need
be furnished for any series for which the Trustee shall be the Security Registrar.


 


Section 5.02          Preservation
Of Information; Communications With Securityholders.


 


(a)            The
Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders
of Securities contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of
holders of Securities received by the Trustee in its capacity as Security Registrar (if acting in such capacity).


 






    20


     


    

 


(b)            The
Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.


 


(c)            Securityholders
may communicate as provided in Section 312(b) of the Trust Indenture Act with other Securityholders with respect to their rights
under this Indenture or under the Securities, and, in connection with any such communications, the Trustee shall satisfy its obligations

Company will at all times comply with Section 314(a) of the Trust Indenture Act. The Company covenants and agrees to provide
(which delivery may be via electronic mail) to the Trustee within 30 days, after the Company files the same with the Commission, copies
of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission
may from time to time by rules and regulations prescribe) that the Company is required to file with the Commission pursuant to Section 13
or Section 15(d) of the Exchange Act; provided, however, the Company shall not be required to deliver to the Trustee any correspondence
filed with the Commission or any materials for which the Company has sought and received confidential treatment by the Commission; and
provided further, that so long as such filings by the Company are available on the Commission’s Electronic Data Gathering, Analysis
and Retrieval System (EDGAR), or any successor system, such filings shall be deemed to have been filed with the Trustee for purposes hereof
without any further action required by the Company. For the avoidance of doubt, a failure by the Company to file annual reports, information
and other reports with the Commission within the time period prescribed thereof by the Commission shall not be deemed a breach of this
Section 5.03.


 


(b)            Delivery
of reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information and
the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable
from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee
is entitled to rely exclusively on an Officer’s Certificate). The Trustee is under no duty to examine any such reports, information
or documents delivered to the Trustee or filed with the Commission via EDGAR to ensure compliance with the provision of this Indenture
or to ascertain the correctness or otherwise of the information or the statements contained therein. The Trustee shall have no responsibility
or duty whatsoever to ascertain or determine whether the above referenced filings with the Commission on EDGAR (or any successor system)
has occurred.

securities exchange upon which any Securities are listed (if so listed) and also with the Commission. The Company agrees to notify the

REMEDIES
OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT


 


Section 6.01          Events
of Default.


 


(a)            Whenever
used herein with respect to Securities of a particular series, “Event of Default” means any one or more of the following events
that has occurred and is continuing:


 


(1)            the
Company defaults in the payment of any installment of interest upon any of the Securities of that series, as and when the same shall become
due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment
period by the Company in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment
of interest for this purpose;


 


(2)            the
Company defaults in the payment of the principal of (or premium, if any, on) any of the Securities of that series as and when the same
shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking
or analogous fund established with respect to that series; provided, however, that a valid extension of the maturity of such Securities
in accordance with the terms of any indenture supplemental hereto shall not constitute a default in the payment of principal or premium,
if any;


 


(3)            the
Company fails to observe or perform any other of its covenants or agreements with respect to that series contained in this Indenture or
otherwise established with respect to that series of Securities pursuant to Section 2.01 hereof (other than a covenant or agreement
that has been expressly included in this Indenture solely for the benefit of one or more series of Securities other than such series)
for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such
notice is a “Notice of Default” hereunder, shall have been given to the Company by the Trustee, by registered or certified
mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Securities of that series at the time
Outstanding;


 


(4)            the
Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a voluntary case, (ii) consents to the entry of
an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially
all of its property or (iv) makes a general assignment for the benefit of its creditors; or


 






    22


     


    

 


(5)            a
court of competent jurisdiction enters an order under any Bankruptcy Law that (i) is for relief against the Company in an involuntary
case, (ii) appoints a Custodian of the Company for all or substantially all of its property or (iii) orders the liquidation
of the Company, and the order or decree remains unstayed and in effect for 90 days.


 


(b)            In
each and every such case (other than an Event of Default specified in clause (4) or clause (5) above), unless the principal
of all the Securities of that series shall have already become due and payable, either the Trustee or the holders of not less than 25%
in aggregate principal amount of the Securities of that series then Outstanding hereunder, by notice in writing to the Company (and to
the Trustee if given by such Securityholders), may declare the principal of (and premium, if any, on) and accrued and unpaid interest
on all the Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and shall
be immediately due and payable. If an Event of Default specified in clause (4) or clause (5) above occurs, the principal of
and accrued and unpaid interest on all the Securities of that series shall automatically be immediately due and payable without any declaration
or other act on the part of the Trustee or the holders of the Securities.


 


(c)            At
any time after the principal of (and premium, if any, on) and accrued and unpaid interest on the Securities of that series shall have
been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered
as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of that series then Outstanding hereunder,
by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company
has paid or deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of that series
and the principal of (and premium, if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration
(with interest upon such principal and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon
overdue installments of interest, at the rate per annum expressed in the Securities of that series to the date of such payment or deposit)
and the amount payable to the Trustee under Section 7.06, and (ii) any and all Events of Default under the Indenture with respect
to such series, other than the nonpayment of principal on (and premium, if any, on) and accrued and unpaid interest on Securities of that
series that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.06.


 


No such rescission and annulment
shall extend to or shall affect any subsequent default or impair any right consequent thereon.


 


(d)            In
case the Trustee shall have proceeded to enforce any right with respect to Securities of that series under this Indenture and such proceedings
shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case, subject to any determination in such proceedings, the Company and the Trustee shall
be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee
shall continue as though no such proceedings had been taken.

Section 6.02          Collection
of Indebtedness and Suits for Enforcement by Trustee.


 


(a)            The
Company covenants that (i) in case it shall default in the payment of any installment of interest on any of the Securities of a series,
or in any payment required by any sinking or analogous fund established with respect to that series as and when the same shall have become
due and payable, and such default shall have continued for a period of 90 days, or (ii) in case it shall default in the payment of
the principal of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon
maturity of the Securities of a series or upon redemption or upon declaration or otherwise then, upon demand of the Trustee, the Company
will pay to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become
due and payable on all such Securities for principal (and premium, if any) or interest, or both, as the case may be, with interest upon
the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon
overdue installments of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06.


 


(b)            If
the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid,
and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against
the Company or other obligor upon the Securities of that series and collect the moneys adjudged or decreed to be payable in the manner
provided by law or equity out of the property of the Company or other obligor upon the Securities of that series, wherever situated.


 


(c)            In
case of any receivership, insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take any action
therein that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such proofs of claim
and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the holders of Securities
of such series allowed for the entire amount due and payable by the Company under the Indenture at the date of institution of such proceedings
and for any additional amount that may become due and payable by the Company after such date, and to collect and receive any moneys or
other property payable or deliverable on any such claim, and to distribute the same after the deduction of the amount payable to the Trustee
under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the holders
of Securities of such 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 such Securityholders, to pay to the Trustee any amount due it under Section 7.06.


 


(d)            All
rights of action and of asserting claims under this Indenture, or under any of the terms established with respect to Securities of that
series, may be enforced by the Trustee without the possession of any of such Securities, or the production thereof at any trial or other
proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of
an express trust, and any recovery of judgment shall, after provision for payment to the Trustee of any amounts due under Section 7.06,
be for the ratable benefit of the holders of the Securities of such series.


 






    24


     


    

 


In case of an Event of Default
hereunder, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate
judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or
in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of
the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture
or by law.


 


Nothing contained herein shall
be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities of that series or the rights of any Securityholder thereof or to authorize
the Trustee to vote in respect of the claim of any Securityholder in any such proceeding.


 


Section 6.03          Application
of Moneys Collected.


 


Any moneys collected by the
Trustee pursuant to this Article with respect to a particular series of Securities shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal (or premium, if any) or interest,
upon presentation of the Securities of that series, and notation thereon of the payment, if only partially paid, and upon surrender thereof
if fully paid:


 


FIRST: To the payment of costs
and expenses of collection and of all amounts payable to the Trustee under Section 7.06;


 


SECOND: To the payment of
the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in respect of which or
for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities for principal (and premium, if any) and interest, respectively; and


 


THIRD: To the payment of the
remainder, if any, to the Company or any other Person lawfully entitled thereto.


 


Section 6.04          Limitation
on Suits.


 


No holder of any Security
of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless (i) such Securityholder previously shall have given to the Trustee written notice of an Event of Default
and of the continuance thereof with respect to the Securities of such series specifying such Event of Default, as hereinbefore provided;
(ii) the holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; (iii) such
Securityholder or Securityholders shall have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities
to be incurred in compliance with such request; (iv) the Trustee for 90 days after its receipt of such notice, request and offer
of indemnity, shall have failed to institute any such action, suit or proceeding and (v) during such 90 day period, the holders of
a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent with the request.


 






    25


     


    

 



 


Notwithstanding anything contained
herein to the contrary or any other provisions of this Indenture, the right of any holder of any Security to receive payment of the principal
of (and premium, if any) and interest on such Security, as therein provided, on or after the respective due dates expressed in such Security
(or in the case of redemption, on the redemption date), or to institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without the consent of such holder and by accepting a Security
hereunder it is expressly understood, intended and covenanted by the taker and holder of every Security of such series with every other
such taker and holder and the Trustee, that no one or more holders of Securities of such series shall have any right in any manner whatsoever
by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other of
such Securities, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Securities of such series.
For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.


 


Section 6.05         Rights
and Remedies Cumulative; Delay or Omission Not Waiver.


 


(a)           Except
as otherwise provided in Section 2.07, all powers and remedies given by this Article to the Trustee or to the Securityholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee
or the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture or otherwise established with respect to such Securities.


 


(b)           No
delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or
an acquiescence therein; and, subject to the provisions of Section 6.04, every power and remedy given by this Article or by
law to the Trustee or the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee
or by the Securityholders.


 






    26


     


    

 


Section 6.06         Control
by Securityholders.


 


The holders of a majority
in aggregate principal amount of the Securities of any series at the time Outstanding, determined in accordance with Section 8.04,
shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee with respect to such series; provided, however, that such direction shall not be in conflict
with any rule of law or with this Indenture or subject the Trustee in its sole discretion to personal liability. Subject to the provisions
of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by
a Responsible Officer or officers of the Trustee, determine that the proceeding so directed, subject to the Trustee’s duties under
the Trust Indenture Act, would involve the Trustee in personal liability or might be unduly prejudicial to the Securityholders not involved
in the proceeding. The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding affected
thereby, determined in accordance with Section 8.04, may on behalf of the holders of all of the Securities of such series waive any
past default in the performance of any of the covenants contained herein or established pursuant to Section 2.01 with respect to
such series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the
Securities of that series as and when the same shall become due by the terms of such Securities otherwise than by acceleration (unless
such default has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited
with the Trustee (in accordance with Section 6.01(c)). Upon any such waiver, the default covered thereby shall be deemed to be cured
for all purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to
their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair
any right consequent thereon.


 


Section 6.07         Undertaking
to Pay Costs.


 


All parties to this Indenture
agree, and each holder of any Securities by such holder’s acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder,
or group of Securityholders, holding more than 10% in aggregate principal amount of the Outstanding Securities of any series, or to any
suit instituted by any Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security
of such series, on or after the respective due dates expressed in such Security or established pursuant to this Indenture.

CONCERNING
THE TRUSTEE


 


Section 7.01         Certain
Duties and Responsibilities of Trustee.


 


(a)           The
Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing of all Events
of Default with respect to the Securities of that series that may have occurred, shall undertake to perform with respect to the Securities
of such series such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants shall be read
into this Indenture against the Trustee. In case an Event of Default with respect to the Securities of a series has occurred (that has
not been cured or waived), the Trustee shall exercise with respect to Securities of that series 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 man would exercise or use under the circumstances
in the conduct of his or her own affairs.


 






    27


     


    

 


(b)            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:


 


(i)            prior
to the occurrence of an Event of Default with respect to the Securities of a series and after the curing or waiving of all such Events
of Default with respect to that series that may have occurred:


 


(A)           the
duties and obligations of the Trustee shall with respect to the Securities of such series be determined solely by the express provisions
of this Indenture, and the Trustee shall not be liable with respect to the Securities of such series except for the performance of such
duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee; and


 


(B)           in
the absence of bad faith on the part of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any 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
or not they conform to the requirements of this Indenture;


 


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


 


(iii)          the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction
of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding 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 that series;


 


(iv)           none
of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for
believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate
indemnity against such risk is not reasonably assured to it;


 






    28


     


    

 


(v)           The
Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder;


 


(vi)          The
permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty of the Trustee; and


 


(vii)         No
Trustee shall have any duty or responsibility for any act or omission of any other Trustee appointed with respect to a series of Securities
hereunder.


 


Section 7.02         Certain
Rights of Trustee.


 


Except as otherwise provided
in Section 7.01:


 


(a)           The
Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, security or other paper or document believed by it to be
genuine and to have been signed or presented by the proper party or parties;


 


(b)           Any
request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by any authorized Officer of the Company (unless other evidence in respect thereof is specifically prescribed
herein);


 


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


 


(d)           The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction
of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity reasonably acceptable to the Trustee against the costs, expenses and liabilities that may be incurred therein or
thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with
respect to a series of the Securities (that has not been cured or waived), to exercise with respect to Securities of that series such
of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent
man would exercise or use under the circumstances in the conduct of his or her own affairs;


 


(e)           The
Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture;


 






    29


     


    

 


(f)            The
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents or inquire as to the performance
by the Company of one of its covenants under this Indenture, unless requested in writing so to do by the holders of not less than a majority
in principal amount of the Outstanding Securities of the particular series affected thereby (determined as provided in Section 8.04);
provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred
by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded
to it by the terms of this Indenture, the Trustee may require security or indemnity reasonably acceptable to the Trustee against such
costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such examination shall be paid by the
Company or, if paid by the Trustee, shall be repaid by the Company upon demand;


 


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


 


(h)           In
no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out
of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents,
acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions
of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts
which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances;


 


(i)            In
no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or
damage and regardless of the form of action; and


 


(j)            The
Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile transmission
or other similar unsecured electronic methods; provided, however, that such instructions or directions shall be signed by an authorized
representative of the party providing such instructions or directions. If the party elects to give the Trustee e-mail or facsimile instructions
(or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s
understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising
directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions
conflict or are inconsistent with a subsequent written instruction. The party providing electronic instructions agrees to assume all risks
arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including without limitation the
risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties. The Trustee may request
that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at
such time to furnish the Trustee with Officer’s Certificates, Company Orders and any other matters or directions pursuant to this
Indenture;


 






    30


     


    




 


(k)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and under the Securities, and each agent,
custodian or other person employed to act under this Indenture; and


 


(l)           The
Trustee shall not be deemed to have knowledge of any Default or Event of Default (other than an Event of Default constituting the failure
to pay the interest on, or the principal of, the Securities if the Trustee also serves as the paying agent for such Securities) until
the Trustee shall have received written notification in the manner set forth in this Indenture or a Responsible Officer of the Trustee
shall have obtained actual knowledge.


 


Section 7.03         Trustee
Not Responsible for Recitals or Issuance or Securities.


 


(a)           The
recitals contained herein and in the Securities shall be taken as the statements of the Company, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee shall not be responsible for any statement in any registration statement, prospectus, or
any other document in connection with the sale of Securities. The Trustee shall not be responsible for any rating on the Securities or
any action or omission of any rating agency.


 


(b)           The
Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities.


 


(c)           The
Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds of such Securities,
or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or established
pursuant to Section 2.01, or for the use or application of any moneys received by any paying agent other than the Trustee.


 


Section 7.04         May Hold
Securities.


 


The Trustee or any paying
agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights
it would have if it were not Trustee, paying agent or Security Registrar.


 


Section 7.05         Moneys
Held in Trust.


 


Subject to the provisions
of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes
for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under
no liability for interest on any moneys received by it hereunder except such as it may agree with the Company to pay thereon.


 


Section 7.06         Compensation
and Reimbursement.


 


(a)           The
Company shall pay to the Trustee for each of its capacities hereunder from time to time compensation for its services as the Company and
the Trustee shall from time to time agree upon in writing. The Trustee’s compensation shall not be limited by any law on compensation
of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred
by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel.


 






    31


     


    

 


(b)           The
Company shall indemnify each of the Trustee in each of its capacities hereunder against any loss, liability or expense (including the
cost of defending itself and including the reasonable compensation and expenses of the Trustee’s agents and counsel) incurred by
it except as set forth in Section 7.06(c) in the exercise or performance of its powers, rights or duties under this Indenture
as Trustee or Agent. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the reasonable
fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably
withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee.


 


(c)           The
Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director,
employee, shareholder or agent of the Trustee through negligence or bad faith.


 


(d)           To
ensure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all funds or
property held or collected by the Trustee, except that held in trust to pay principal of or interest on particular Securities. When the
Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(4) or (5), the
expenses (including the reasonable fees and expenses of its counsel) and the compensation for services in connection therewith are to
constitute expenses of administration under any bankruptcy law. The provisions of this Section 7.06 shall survive the termination
of this Indenture and the resignation or removal of the Trustee.


 


Section 7.07         Reliance
on Officer’s Certificate.


 


Except as otherwise provided
in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it reasonably necessary
or desirable that a matter be proved or established prior to taking or suffering or omitting to take any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part
of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee and such
certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action
taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.


 


Section 7.08         Disqualification;
Conflicting Interests.


 


If the Trustee has or shall
acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee
and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.


 






    32


     


    

 


Section 7.09         Corporate
Trustee Required; Eligibility.


 


There shall at all times be
a Trustee with respect to the Securities issued hereunder which shall at all times be a corporation organized and doing business under
the laws of the United States of America or any state or territory thereof or of the District of Columbia, or a corporation or other Person
permitted to act as trustee by the Commission, authorized under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial,
or District of Columbia authority.


 


If such corporation or other
Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such corporation or other Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. The Company may not, nor may
any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee. In case at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in
the manner and with the effect specified in Section 7.10.


 


Section 7.10         Resignation
and Removal; Appointment of Successor.


 


(a)           The
Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by giving written
notice thereof to the Company and the Securityholders of such series. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee with respect to Securities of such series by written instrument, in duplicate, executed by order of the Board
of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor
trustee shall have been so appointed and have accepted appointment within 30 days after the sending of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities
of such series, or any Securityholder of that series who has been a bona fide holder of a Security or Securities for at least six months
may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.


 


(b)           In
case at any time any one of the following shall occur:


 


(i)           the
Trustee shall fail to comply with the provisions of Section 7.08 after written request therefor by the Company or by any Securityholder
who has been a bona fide holder of a Security or Securities for at least six months; or


 


(ii)         the
Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request
therefor by the Company or by any such Securityholder; or


 






    33


     


    

 


(iii)         the
Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding,
or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;


 


then, in any such case, the
Company may remove the Trustee with respect to all Securities and appoint a successor trustee by written instrument, in duplicate, executed
by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or any Securityholder who has been a bona fide holder of a Security or Securities for at least six months may, on behalf of that
holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.


 


(c)           The
holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding may at any time remove the
Trustee with respect to such series by so notifying the Trustee and the Company and may appoint a successor Trustee for such series with
the consent of the Company.


 


(d)           Any
resignation or removal of the Trustee and appointment of a successor trustee with respect to the Securities of a series pursuant to any
of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.11.


 


(e)           Any
successor trustee appointed pursuant to this Section may be appointed with respect to the Securities of one or more series or all
of such series, and at any time there shall be only one Trustee with respect to the Securities of any particular series.


 


Section 7.11         Acceptance
of Appointment By Successor.


 


(a)           In
case of the appointment hereunder of a successor trustee with respect to all Securities, every such successor trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the
successor trustee, such retiring Trustee shall, upon payment of any amounts due to it pursuant to the provisions of Section 7.06,
execute and deliver an instrument transferring to such successor trustee all the rights, powers, and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor trustee all property and money held by such retiring Trustee hereunder.


 






    34


     


    

 


(b)           In
case of the appointment hereunder of a successor trustee with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment and which (i) 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,
(ii) 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 (iii) shall add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee
and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall with respect to the Securities of that or those series to which the appointment of such successor
trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations
vested in the Trustee under this Indenture, 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, to the extent contemplated by such supplemental indenture, the property
and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such
successor trustee relates.


 


(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.


 


(d)           No
successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible
under this Article.


 


(e)           Upon
acceptance of appointment by a successor trustee as provided in this Section, the Company shall send notice of the succession of such
trustee hereunder to the Securityholders. If the Company fails to send such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be sent at the expense of the Company.


 


Section 7.12         Merger,
Conversion, Consolidation or Succession to Business.


 


Any corporation into which
the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, including the administration of the trust created by this Indenture, shall be the successor of the Trustee hereunder,
provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.09,
without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding. 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.


 






    35


     


    

 


Section 7.13         Preferential
Collection of Claims Against the Company.


 


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


 


Section 7.14         Notice
of Default.


 


If any Event of Default occurs
and is continuing and if such Event of Default is known to a Responsible Officer of the Trustee, the Trustee shall send to each Securityholder
in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act notice of the Event of Default within
the earlier of 90 days after it occurs and 30 days after it is known to a Responsible Officer of the Trustee or written notice of it is
received by the Trustee, unless such Event of Default has been cured; provided, however, that, except in the case of a default
in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in withholding such
notice if and so long as the Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the
interest of the Securityholders.

CONCERNING
THE SECURITYHOLDERS


 


Section 8.01         Evidence
of Action by Securityholders.


 


Whenever in this Indenture
it is provided that the holders of a majority or specified percentage in aggregate principal amount of the Securities of a particular
series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of
any other action), the fact that at the time of taking any such action the holders of such majority or specified percentage of that series
have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of Securities
of that series in person or by agent or proxy appointed in writing.


 


If the Company shall solicit
from the Securityholders of any series any request, demand, authorization, direction, notice, consent, waiver or other action, the Company
may, at its option, as evidenced by an Officer’s Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company
shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver
or other action may be given before or after the record date, but only the Securityholders of record at the close of business on the record
date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of the requisite proportion of Outstanding
Securities of that series have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver
or other action, and for that purpose the Outstanding Securities of that series shall be computed as of the record date; provided, however,
that no such authorization, agreement or consent by such Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six months after the record date.


 






    36


     


    

 


Section 8.02         Proof
of Execution by Securityholders.


 


Subject to the provisions
of Section 7.01, proof of the execution of any instrument by a Securityholder (such proof will not require notarization) or his or
her agent or proxy and proof of the holding by any Person of any of the Securities shall be sufficient if made in the following manner:


 


(a)           The
fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.


 


(b)           The
ownership of Securities shall be proved by the Security Register of such Securities or by a certificate of the Security Registrar thereof.


 


The Trustee may require such additional proof
of any matter referred to in this Section as it shall deem necessary.


 


Section 8.03         Who
May be Deemed Owners.


 


Prior to the due presentment
for registration of transfer of any Security, the Company, the Trustee, any paying agent and any Security Registrar may deem and treat
the Person in whose name such Security shall be registered upon the books of the Security Registrar as the absolute owner of such Security
(whether or not such Security shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than
the Security Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03)
interest on such Security and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any Security Registrar
shall be affected by any notice to the contrary.


 


Section 8.04         Certain
Securities Owned by Company Disregarded.


 


In determining whether the
holders of the requisite aggregate principal amount of Securities of a particular series have concurred in any direction, consent or waiver
under this Indenture, the Securities of that series that are owned by the Company or any other obligor on the Securities of that series
or by any Person directly or indirectly controlling or controlled by or under common control with the Company or any other obligor on
the Securities of that series shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except
that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Securities
of such series that the Trustee actually knows are so owned shall be so disregarded. The Securities so owned that have been pledged in
good faith may be regarded as Outstanding for the purposes of this Section, if the pledgee shall establish to the satisfaction of the
Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.
