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(1)(j). 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(1)(p), the principal of and the interest on the Securities of
any series, as well as any premium thereon in case of redemption thereof prior to maturity, 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.


 




    	6



     


    

 


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.


 


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


 


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


 


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


 


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


 


In
authenticating such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, if requested, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion
of Counsel stating that the form and terms thereof have been established 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.


 


(1)
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.


 


(2)
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.


 




    	8



     


    

 


(3)
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, 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(2) and
Section 9.04 not involving any transfer.


 


(4)
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, other than the unredeemed portion of any such Securities being redeemed in part.
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.


 


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.


 




    	9



     


    

 


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, exchange or registration of transfer shall, if surrendered to the Company
or any paying 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 (and, with respect to the provisions of Article Fourteen, the holders of any indebtedness
of the Company to which the Securities of any series are subordinated) 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 (and, with respect to the provisions of Article Fourteen, the holders of any indebtedness of the Company to which
the Securities of any series are subordinated).


 


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 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.


 


(1)
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 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.”


 


(2)
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.


 


(3)
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(3) 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.


 


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.


 




    	11



     


    

 


Section
3.02 Notice of Redemption.


 


(1)
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, 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 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.


 


(2)
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.


 


Section
3.03 Payment Upon Redemption.


 


(1)
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).


 


(2)
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.


 


Article

COVENANTS


 


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.


 




    	13



     


    

 


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.


 


(1)
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:


 


(a)
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;


 


(b)
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;


 


(c)
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


 


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


 


(2)
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.


 


(3)
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
5.01 Company to Furnish Trustee Names and Addresses of Securityholders.


 


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


 


Section
5.02 Preservation Of Information; Communications With Securityholders.


 


(1)
The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders

of Securities received by the Trustee in its capacity as Security Registrar (if acting in such capacity)


 


(2)
The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.


 


(3)
Securityholders may communicate as provided in Section 312(b) of the Trust Indenture Act with other Securityholders with respect to their

portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) that the Company is required
to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, the Company shall not be

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 Interactive Data Electronic Applications (IDEA), 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; provided that an
electronic link to such filing, together with an electronic notice of such filing have been sent to the Trustee. 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.

(2)
Delivery of reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information

is entitled to rely exclusively on an Officer’s Certificate).

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT


 


Section
6.01 Events of Default.


 


(1)
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:


 


(a)
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;


 


(b)
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;


 


(c)
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;


 




    	16



     


    

 


(d)
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


 


(e)
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.


 


(2)
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.


 


(3)
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.


 


(4)
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.


 


(1)
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.


 




    	17



     


    

 


(2)
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.


 


(3)
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.


 


(4)
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 all indebtedness of the Company to which such series of Securities is subordinated to the extent required by Section
7.06 and any subordination terms of the series specified as contemplated by Article Fourteen;


 




    	18



     


    

 


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 or any Security
to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, any Security 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 such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby; (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.


 


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


 


(1)
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.


 


(2)
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(3)). Upon any such waiver, the default covered thereby shall be deemed to be cured
for all purposes of this Indenture and the Company, the Trustee and the holders of the Securities of such series shall be restored to
their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair
any right consequent thereon.


 


Section
6.07 Undertaking to Pay Costs.


 


All
parties to this Indenture agree, and each holder of any Securities by such holder’s acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or
in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’
fees, 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.


 


(1)
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 own affairs.


 




    	20



     


    

 


(2)
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:


 


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


 


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


 


(B)
in the absence of bad faith on the part of the Trustee, the Trustee may with respect to the Securities of such series conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished
to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions that by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine
whether or not they conform to the requirements of this Indenture;


 


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


 


(c)
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction
of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee under this Indenture with respect to the Securities of that series; and


 


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


 


Section
7.02 Certain Rights of Trustee.


 


Except
as otherwise provided in Section 7.01:


 


(1)
The Trustee may 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;


 


(2)
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);


 


(3)
The Trustee may consult with counsel and the 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;


 


(4)
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 reasonable security or indemnity 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 own affairs;


 




    	21



     


    

 


(5)
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;


 


(6)
The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents, 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 reasonable
indemnity 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;


 


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


 


(8)
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;


 


(9)
In no event shall the Trustee be responsible or liable for special, indirect, 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


 


(10)
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.


 


In
addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default 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.


 


(1)
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.


 


(2)
The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities.


 


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


 


Section
7.04 May Hold Securities.


 


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

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.


 


(1)
The Company covenants and agrees to pay to the Trustee, and the Trustee shall be entitled to, such reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee
may from time to time agree in writing, for all services rendered by it in the execution of the trusts hereby created and in the exercise
and performance of any of the powers and duties hereunder of the Trustee, and, except as otherwise expressly provided herein, the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements
of its counsel and of all Persons not regularly in its employ), except any such expense, disbursement or advance as may arise from its
negligence or bad faith and except as the Company and Trustee may from time to time agree in writing. The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense
incurred without negligence or bad faith on the part of the Trustee and arising out of or in connection with the acceptance or administration
of this trust, including the reasonable costs and expenses of defending itself against any claim of liability in the premises.


 


(2)
The obligations of the Company under this Section to compensate and indemnify the Trustee and to pay or reimburse the Trustee for reasonable
expenses, disbursements and advances shall constitute indebtedness of the Company to which the Securities are subordinated. Such additional indebtedness shall be secured
by a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in
trust for the benefit of the holders of particular Securities.


 


(3)
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(1)(d) or (1)(e), 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.

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.

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.

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

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.


 




    	24



     


    

 


(2)
In case at any time any one of the following shall occur:

therefor by the Company or by any such Securityholder; or


 


(c)
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

remove the Trustee and appoint a successor trustee.

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.

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,

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.

any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business

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

with the same effect as if such successor Trustee had itself authenticated such Securities.


 


Section
7.13 Preferential Collection of Claims Against the Company.

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 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:


 


(1)
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.


 


(2)
The ownership of Securities shall be proved by the Security Register of such Securities or by a certificate of the Security Registrar
thereof.


 


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


 


Section
8.03 Who May be Deemed Owners.


 


Prior
to the due presentment for registration of transfer of any Security, the Company, the Trustee, any paying agent and any Security Registrar
may deem and treat the Person in whose name such Security shall be registered upon the books of the Company 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.


 




    	27



     


    

 


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.

supplemental indenture authorized by the provisions of this Section may be executed by the Company and the Trustee without the consent
of the holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02.


 


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
9.04 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

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 corporation (whether or not affiliated with the Company or its successor or
successors) authorized to acquire and operate the same; provided, however, (a) 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), sale, conveyance, transfer or other
disposition, the due and punctual payment of the principal of (premium, if any) and interest on all of the Securities of all series in
accordance with the terms of each series, according to 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 effect) reasonably satisfactory in form to the Trustee executed and delivered to the Trustee by the entity
formed by such consolidation, or into which the Company shall have been merged, or by the entity which shall have acquired such property
and (b) in the event that the Securities of any series then Outstanding are convertible into or exchangeable for shares of common stock
or other securities of the Company, such entity shall, by such supplemental indenture, make provision so that the Securityholders of
Securities of that series shall thereafter be entitled to receive upon conversion or exchange of such Securities the number of securities
or property to which a holder of the number of shares of common stock or other securities of the Company deliverable upon conversion
or exchange of those Securities would have been entitled had such conversion or exchange occurred immediately prior to such consolidation,
merger, sale, conveyance, transfer or other disposition.

by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the obligations set forth

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
