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.


 


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 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 mailed, first class postage prepaid,
to each Securityholder at his or her address as it appears in the Security Register (as hereinafter defined), 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 mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Securities (or their respective Predecessor
Securities) are registered on such special record date.


 






    8 


     


    

 


(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 15th 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 15th day of a month, whether or not such date is a Business Day.


 


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.


 






    9 


     


    

 



 


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.


 


(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 (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.


 


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.


 






    10


     


    

 


(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 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 mailing 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 mailing, 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.


 


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 holders), 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.


 






    11


     


    

 


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.


 


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.


 






    12


     


    

 


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.


 


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.


 


(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 Holders; provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be
placed only on the other 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.

Article

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.


 


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, first
class postage prepaid (or with regard to any Global Security held in book entry form, by electronic mail), 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 holders
at their last addresses as they shall appear upon the Security Register, 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 Trustee shall select, by lot or in such other manner as
it 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.


 






    14


     


    

 


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 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 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 holder 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.


 


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 series
pursuant to Section 3.05 and the basis for such credit and will, together with such Officer’s Certificate, deliver to the Trustee
any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select
the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.02 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.02. Such notice
having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 3.03.

Section 4.01      
Payment of Principal, Premium and Interest.


 


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 made at the time provided
herein and established with respect to such Securities by U.S. dollar check drawn on and mailed to the address of the Securityholder
entitled thereto as such address shall appear in the Security Register, or U.S. dollar wire transfer to, a U.S. dollar account
if such Securityholder shall have furnished wire instructions to the Trustee no later than 15 days prior to the relevant payment
date. Payments of interest on the Securities may be made at the time provided herein and established with respect to such Securities by
U.S. dollar check mailed to the address of the Securityholder entitled thereto as such address shall appear in the Security Register,
or U.S. dollar wire transfer to, a U.S. dollar account if such Securityholder shall have furnished wire instructions in writing
to the Security Registrar and the Trustee no later than 15 days prior to the relevant payment date.


 


Section 4.02      
Maintenance of Office or Agency.


 


So long as any series of the Securities remain
Outstanding, the Company agrees to maintain an office or agency with respect to each such series and at such other location or locations
as may be designated as provided in this Section 4.02, where (i) Securities of that series may be presented for payment, (ii) Securities
of that series may be presented as herein above authorized for registration of transfer and exchange, and (iii) notices and demands
to or upon the Company in respect of the Securities of that series and this Indenture may be given or served, such designation to continue
with respect to such office or agency until the Company shall, by written notice signed by any officer authorized to sign an Officer’s
Certificate and delivered to the Trustee, designate some other office or agency for such purposes or any of 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.


 






    16


     


    

 


(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.


 


(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.


 


Section 4.04      
Appointment to Fill Vacancy in Office of Trustee.


 


The
Company, whenever necessary 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 shall at all times be a Trustee hereunder.

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

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 SEC within the
time period prescribed thereof by the Commission shall not be deemed a breach of this Section 5.03.


 






    18 


     


    

 


(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 SEC 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 SEC on EDGAR (or any
successor system) has occurred.

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;


 






    19 


     


    

 


(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


 


(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.


 






    20 


     


    

 


(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.


 






    21 


     


    

 


(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.


 


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 holder 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;


 






    22 


     


    

 


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 holder 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 holder or holders 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.


 


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.


 






    23 


     


    

 


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.


 


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.


 






    24 


     


    

 


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.


 


(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


 






    25 


     


    

 


(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

(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

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);


 






    26 


     


    

 


(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;


 


(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;






 






    27 


     


    

 



 


(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 (a) the party providing such written instructions,
subsequent to such transmission of written instructions, shall provide the originally executed instructions or directions to the Trustee
in a timely manner, and (b) such originally executed 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.


 


(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.


 


(l)        
The Trustee shall not be deemed to have knowledge of any Default or Event of Default (other than an Event of Default relating
to the failure to pay the interest on, or the principal of, the 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.


 






    28 


     


    

 


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.


 


(b)        
The Company shall indemnify 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.


 






    29 


     


    

 


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.


 


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.


 






    30 


     


    

 


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 by transmitting notice of resignation by mail, first class postage prepaid, to the
Securityholders of such series, as their names and addresses appear upon the Security Register. 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 mailing 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


 


(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.


 






    31 


     


    

 


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 its charges, execute and deliver an instrument transferring
to such successor trustee all the rights, powers, and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such
successor trustee all property and money held by such retiring Trustee hereunder.


 


(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 transmit notice of the
succession of such trustee hereunder by mail, first class postage prepaid, to the Securityholders, as their names and addresses appear
upon the Security Register. If the Company fails to transmit such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be transmitted 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.


 


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 mail 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.

Article

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.


 


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.


 






    34 


     


    

 


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.


 


Section 8.05      
Actions Binding on Future Securityholders.


 


At any time prior to (but not after) the evidencing
to the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the majority or percentage in aggregate
principal amount of the Securities of a particular series specified in this Indenture in connection with such action, any holder of a
Security of that series that is shown by the evidence to be included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 8.02, revoke such action so far
as concerns such Security. Except as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon
such holder and upon all future holders and owners of such Security, and of any Security issued in exchange therefor, on registration
of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any
action taken by the holders of the majority or percentage in aggregate principal amount of the Securities of a particular series specified
in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the holders of
all the Securities of that series.

The Trustee is hereby authorized to join with the

Section 9.02      
Supplemental Indentures With Consent of Securityholders.


 


With the consent (evidenced as provided in Section 8.01)
of the holders of not less than a majority in aggregate principal amount of the Securities of each series affected by such supplemental
indenture or indentures at the time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may from time to
time and at any time enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture
Act as then in effect) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner not covered by Section 9.01 the rights of the holders of
the Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent
of the holders of each Security then Outstanding and affected thereby, (a) extend the fixed maturity of any Securities of any series,
or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable
upon the redemption thereof or (b) reduce the aforesaid percentage of Securities, the holders of which are required to consent to
any such supplemental indenture.


 


It shall not be necessary for the consent of the
Securityholders of any series affected thereby under this Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such consent shall approve the substance thereof.


 


Section 9.03      
Effect of Supplemental Indentures.


 


Upon the execution of any supplemental indenture
pursuant to the provisions of this Article or of Section 10.01, this Indenture shall, with respect to such series, be and be deemed
to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Securities of the series affected thereby shall thereafter be determined,
exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any
such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.


 


Section 9.04       Securities Affected by Supplemental Indentures.


 


Securities of any series affected by a supplemental indenture, authenticated
and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article or of Section 10.01, may bear
a notation in form approved by the Company, provided such form meets the requirements of any securities exchange upon which such series
may be listed, as to any matter provided for in such supplemental indenture. If the Company
shall so determine, new Securities of that series so modified as to conform, in the opinion of the Board of Directors, to any modification
of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered
in exchange for the Securities of that series then Outstanding.

Section 9.05      
Execution of Supplemental Indentures.


 


Upon the request of the Company, accompanied by
its Board Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of
the consent of Securityholders required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The
Trustee, subject to the provisions of Section 7.01, shall receive an Officer’s Certificate or an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is authorized or permitted by the terms of this Article and
that all conditions precedent to the execution of the supplemental indenture have been complied with; provided, however, that such Officer’s
Certificate or Opinion of Counsel need not be provided in connection with the execution of a supplemental indenture that establishes the
terms of a series of Securities pursuant to Section 2.01 hereof.


 


Promptly after the execution by the Company and
the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall (or shall direct the Trustee to)
transmit by mail, first class postage prepaid, a notice, setting forth in general terms the substance of such supplemental indenture,
to the Securityholders of all series affected thereby as their names and addresses appear upon the Security Register. Any failure of the
Company to mail, or cause the mailing of, such notice, or any defect therein, shall not, however, in any way impair or affect the validity
of any such supplemental indenture.

SUCCESSOR ENTITY


 


Section 10.01  
Company May Consolidate, Etc.


 


Nothing contained in this Indenture shall
prevent any consolidation or merger of the Company with or into any other Person (whether or not affiliated with the Company) or
successive consolidations or mergers in which the Company or its successor or successors shall be a party or parties, or shall
prevent any sale, conveyance, transfer or other disposition of the property of the Company or its successor or successors as an
entirety, or substantially as an entirety, to any other Person (whether or not affiliated with the Company or its successor or
successors); provided, however, the Company hereby covenants and agrees that, upon any such consolidation or merger (in each case,
if the Company is not the survivor of such transaction) or any such sale, conveyance, transfer or other disposition (other than a
sale, conveyance, transfer or other disposition to a Subsidiary of the Company), the due and punctual payment of the principal of

their tenor, and the due and punctual performance and observance of all the covenants and conditions of this Indenture with respect
to each series or established with respect to such series pursuant to Section 2.01 to be kept or performed by the Company shall
be expressly assumed, by supplemental indenture (which shall conform to the provisions of the Trust Indenture Act, as then in

consolidation, or into which the Company shall have been merged, or by the entity which shall have acquired such property.

entity by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the obligations set
forth under Section 10.01 on all of the Securities of all series Outstanding, such successor entity shall succeed to and be substituted
for the Company with the same effect as if it had been named as the Company herein, and thereupon the predecessor corporation shall be
relieved of all obligations and covenants under this Indenture and the Securities.


 


(b)             
In case of any such consolidation, merger, sale, conveyance, transfer or other disposition, such changes in phraseology and
form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate.


 


(c)              
Nothing contained in this Article shall require any action by the Company in the case of a consolidation or merger of any Person
into the Company where the Company is the survivor of such transaction, or the acquisition by the Company, by purchase or otherwise, of
all or any part of the property of any other Person (whether or not affiliated with the Company).

as provided in Section 2.07 and Securities for whose payment money or Governmental Obligations have theretofore been deposited
in trust or segregated and held in trust by the Company and thereupon repaid to the Company or discharged from such trust, as

Obligations or a combination thereof, sufficient in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay at maturity or upon redemption all Securities of that
series not theretofore delivered to the Trustee for cancellation, including principal (and premium, if any) and interest due or to
become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company shall also pay or cause to
be paid all other sums payable hereunder with respect to such series by the Company then this Indenture shall thereupon cease to be
of further effect with respect to such series except for the provisions of Sections 2.03, 2.05, 2.07, 4.01, 4.02, 4.03
and 7.10, that shall survive until the date of maturity or redemption date, as the case may be, and Sections 7.06

sufficient to pay at maturity or upon redemption all such Securities of that series not theretofore delivered to the Trustee for cancellation,
including principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as
the case may be, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company with respect to
such series, then after the date such moneys or Governmental Obligations, as the case may be, are deposited with the Trustee the obligations
of the Company under this Indenture with respect to such series shall cease to be of further effect except for the provisions of Sections 2.03,
2.05, 2.07, 4,01, 4.02, 4,03, 7.06, 7.10 and 11.05 hereof that shall survive until such Securities shall mature and be paid.

survive.


 


Section 11.03  
Deposited Moneys to be Held in Trust.


 


All moneys or Governmental Obligations deposited
with the Trustee pursuant to Sections 11.01 or 11.02 shall be held in trust and shall be available for payment as due, either

Securities for the payment or redemption of which such moneys or Governmental Obligations have been deposited with the Trustee.


 


Section 11.04  
Payment of Moneys Held by Paying Agents.


 


In connection with the satisfaction and discharge
of this Indenture all moneys or Governmental Obligations then held by any paying agent under the provisions of this Indenture shall, upon
demand of the Company, be paid to the Trustee and thereupon such paying agent shall be released from all further liability with respect
to such moneys or Governmental Obligations.

with any paying agent or the Trustee, or then held by the Company, in trust for payment of principal of or premium, if any, or interest
on the Securities of a particular series that are not applied but remain unclaimed by the holders of such Securities for at least two
years after the date upon which the principal of (and premium, if any) or interest on such Securities shall have respectively become due
and payable, or such other shorter period set forth in applicable escheat or abandoned or unclaimed property law, shall be repaid to the
Company on May 31 of each year or upon the Company’s request or (if then held by the Company) shall be discharged from such
trust; and thereupon the paying agent and the Trustee shall be released from all further liability with respect to such moneys or Governmental
Obligations, and the holder of any of the Securities entitled to receive such payment shall thereafter, as a general creditor, look only
