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.


 






    6 


     


    

 


(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.


 


(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.


 






    8 


     


    

 


Section 2.07          Mutilated,
Destroyed, Lost or Stolen Securities.


 


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


 


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


 


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


 


Section 2.08          Cancellation.


 


All Securities surrendered for the purpose of payment, redemption,
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).


 






    9 


     


    

 


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 3


 


REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS


 


Section 3.01          Redemption.


 


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


 


Section 3.02          Notice
of Redemption.


 


(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.


 






    11 


     


    

 


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 4


 


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.


 


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.


 






    13 


     


    

 


(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 4.04          Appointment
to Fill Vacancy in Office of Trustee.


 


The Company, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so that there shall at all times be a Trustee
hereunder.


 


Section 4.05          Compliance
with Consolidation Provisions.


 


The Company will not, while any of the Securities remain Outstanding,
consolidate with or merge into any other Person, in either case where the Company is not the survivor of such transaction, or sell or
convey all or substantially all of its property to any other Person unless the provisions of Article Ten hereof are complied with.


 


Article 5


 


SECURITYHOLDERS’ LISTS AND REPORTS BY
THE COMPANY AND THE TRUSTEE


 


Section 5.01          Company
to Furnish Trustee Names and Addresses of Securityholders.

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 contained in the most recent list furnished to it as provided in Section 5.01 and as to the names and addresses of
holders of Securities received by the Trustee in its capacity as Security Registrar (if acting in such capacity)


 


(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 rights
under this Indenture or under the Securities, and, in connection with any such communications, the Trustee shall satisfy its obligations

Section 5.03          Reports
by the Company.


 


(1)            The
Company covenants and agrees to provide (which delivery may be via electronic mail) to the Trustee within 30 days, after the Company
files the same with the Commission, copies of the annual reports and of the information, documents and other reports (or copies of such
portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) that the Company is
required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, the
Company shall not be required to deliver to the Trustee any materials for which the Company has sought and received confidential treatment
by the Commission; and provided further, that so long as such filings by the Company are available on the Commission’s Electronic
Data Gathering, Analysis and Retrieval System (EDGAR), or 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 and
the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable
from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee
is entitled to rely exclusively on an Officer’s Certificate).


 


Section 5.04          Reports
by the Trustee.


 


(1)            If
required by Section 313(a) of the Trust Indenture Act, the Trustee, within sixty (60) days after each May 1, shall transmit

report dated as of such May 1, which complies with Section 313(a) of the Trust Indenture Act.

to Securityholders, be filed by the Trustee with the Company, with each securities exchange upon which any Securities are listed (if
so listed) and also with the Commission. The Company agrees to notify the Trustee when any Securities become listed on any securities
exchange.


 


Article 6


 


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;


 






    15 


     


    

 


(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;


 


(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.


 


(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;


 






    17 


     


    

 



 


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.


 






    18 


     


    

 


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 Responsible 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.


 


Article 7


 


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.


 


(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;


 






    19 


     


    




 


(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;


 


(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;


 






    20 


     


    




 


(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.


 






    21 


     


    

 


Section 7.05           Moneys Held
in Trust.


 


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


 


Section 7.06           Compensation
and Reimbursement.


 


(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.


 


Section 7.07           Reliance on Officer’s
Certificate.


 


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


 


Section 7.08           Disqualification;
Conflicting Interests.


 


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


 






    22 


     


    

 


Section 7.09          Corporate Trustee
Required; Eligibility.


 


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


 


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


 


Section 7.10           Resignation and
Removal; Appointment of Successor.


 


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


 


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


 


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


 


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


 


(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 and the appointment of a successor trustee. Such
court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.


 


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


 


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


 






    23 


     


    

 


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


 


Section 7.11           Acceptance of
Appointment By Successor.


 


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


 


(2)            In
case of the appointment hereunder of a successor trustee with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain such provisions as shall
be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor trustee relates,
(ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee
and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall with respect to the Securities of that or those series to which the appointment of such successor
trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations
vested in the Trustee under this Indenture, and each such successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor trustee relates; but, on request of the Company or any successor trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the property
and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such
successor trustee relates.


 


(3)            Upon
request of any such successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming
to such successor trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case
may be.


 


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


 


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


 






    24 


     


    

 


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


 


Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, including the administration of the trust
created by this Indenture, shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified under the
provisions of Section 7.08 and eligible under the provisions of Section 7.09, without the execution or filing of any paper
or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case any Securities
shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.


 


Section 7.13           Preferential
Collection of Claims Against the Company.


 


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


 


Section 7.14           Notice of Default.


 


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


 


Article 8


 


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.


 






    25 


     


    

 


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.


 


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.

and delivery of Securities, as herein set forth;


 


(6)            to

of any such supplemental indenture, and to make any further appropriate agreements and stipulations that may be therein contained, but
the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties or
immunities under this Indenture or otherwise.


 


Any 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 of any supplemental indenture or of modifying in any manner not covered by Section 9.01 the rights of the holders of the Securities

    27 


     


    

 


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


 


Section 9.03           Effect of Supplemental
Indentures.


 


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


 


Section 9.04           Securities Affected
by Supplemental Indentures.


 


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


 


Section 9.05           Execution of
Supplemental Indentures.


 


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


 


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

Article 10


 


SUCCESSOR ENTITY


 


Section 10.01          Company May Consolidate,
Etc.


 


Nothing contained in this Indenture shall prevent any consolidation
or merger of the Company with or into any other Person (whether or not affiliated with the Company) or successive consolidations or mergers
in which the Company or its successor or successors shall be a party or parties, or shall prevent any sale, conveyance, transfer or other
disposition of the property of the Company or its successor or successors as an entirety, or substantially as an entirety, to any other
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.


 







Section 10.02          Successor Entity
Substituted.


 


(1)            In
case of any such consolidation, merger, sale, conveyance, transfer or other disposition and upon the assumption by the successor entity
by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the obligations set forth
under Section 10.01 on all of the Securities of all series Outstanding, such successor entity shall succeed to and be substituted
for the Company with the same effect as if it had been named as the Company herein, and thereupon the predecessor corporation shall be
relieved of all obligations and covenants under this Indenture and the Securities.


 


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


 


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

Securities that shall have been destroyed, lost or stolen and that shall have been replaced or paid as provided in Section 2.07 and
Securities for whose payment money or Governmental Obligations have theretofore been deposited in trust or segregated and held in trust
by the Company and thereupon repaid to the Company or discharged from such trust, as provided in Section 11.05); or (b) all
such Securities of a particular series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory
to the Trustee for the giving of notice of redemption, and the Company shall deposit or cause to be deposited with the Trustee as trust
funds the entire amount in moneys or Governmental Obligations or a combination thereof, sufficient in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay at maturity or upon
redemption all Securities of that series not theretofore delivered to the Trustee for cancellation, including principal (and premium,
if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may be, and if the Company
shall also pay or cause to be paid all other sums payable hereunder with respect to such series by the Company then this Indenture shall
thereupon cease to be of further effect with respect to such series except for the provisions of Sections 2.03, 2.05, 2.07, 4.01, 4.02,
4.03 and 7.10, that shall survive until the date of maturity or redemption date, as the case may be, and Sections 7.06 and 11.05, that
shall survive to such date and thereafter, and the Trustee, on demand of the Company and at the cost and expense of the Company shall
execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to such series.


 






    29 


     


    

 


Section 11.02          Discharge of
Obligations.


 


If at any time all such Securities of a particular series not heretofore
delivered to the Trustee for cancellation or that have not become due and payable as described in Section 11.01 shall have been paid
by the Company by depositing irrevocably with the Trustee as trust funds moneys or an amount of Governmental Obligations sufficient to
pay at maturity or upon redemption all such Securities of that series not theretofore delivered to the Trustee for cancellation, including
principal (and premium, if any) and interest due or to become due to such date of maturity or date fixed for redemption, as the case may
be, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company with respect to such series,
then after the date such moneys or Governmental Obligations, as the case may be, are deposited with the Trustee the obligations of the
Company under this Indenture with respect to such series shall cease to be of further effect except for the provisions of Sections 2.03,
2.05, 2.07, 4,01, 4.02, 4,03, 7.06, 7.10 and 11.05 hereof that shall survive until such Securities shall mature and be paid.


 


Thereafter, Sections 7.06 and 11.05 shall survive.


 


Section 11.03          Deposited Moneys
to be Held in Trust.


 


All moneys or Governmental Obligations deposited with the Trustee pursuant
to Sections 11.01 or 11.02 shall be held in trust and shall be available for payment as due, either directly or through any paying agent
(including the Company acting as its own paying agent), to the holders of the particular series of Securities for the payment or redemption
of which such moneys or Governmental Obligations have been deposited with the Trustee.


 


Section 11.04          Payment of Moneys
Held by Paying Agents.


 


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


 


Section 11.05          Repayment to
Company.


 


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

directly or through the Company or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that this Indenture and the obligations
issued hereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred
by, the incorporators, stockholders, officers or directors as such, of the Company or of any predecessor or successor corporation, or
any of them, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements
