portion thereof is called for redemption and the redemption date is subsequent to a regular record date with respect to any Interest
Payment Date and prior to such Interest Payment Date, interest on such Security will be paid upon presentation and surrender of
such Security as provided in Section 3.03.


 


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


 


(1) The
Company may make payment of any Defaulted Interest on Securities to the Persons in whose names such Securities (or their respective
Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest,
which shall be fixed in the following manner: the Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each such Security and the date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon
the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall not be more than 15 nor less
than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice
of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor
to be mailed, first class postage prepaid, to each Securityholder at his or her address as it appears in the Security Register
(as hereinafter defined), not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted
Interest and the special record date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons
in whose names such Securities (or their respective Predecessor Securities) are registered on such special record date.


 


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


 


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


 


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

Section 2.04
Execution and Authentications.


 


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


 


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


 


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


 


In authenticating
such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee
shall be entitled to receive, 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.


 


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


 


(b) The
Company shall keep, or cause to be kept, at its office or agency designated for such purpose or such other location designated
by the Company, 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.


 




    	 	-11-	 



     


    

 


(c) Except
as provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officers’ 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(b) and Section 9.04 not involving any transfer.


 


(d) The
Company shall not be required (i) to issue, exchange or register the transfer of any Securities during a period beginning
at the opening of business 15 days before the day of the mailing of a notice of redemption of less than all the Outstanding Securities
of the same series and ending at the close of business on the day of such mailing, nor (ii) to register the transfer of or
exchange any Securities of any series or portions thereof called for redemption, 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.


 


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 such purpose and the Trustee shall
authenticate and such office or agency shall deliver in exchange for such temporary Securities an equal aggregate principal amount
of definitive Securities of such series, unless the Company advises the Trustee to the effect that definitive Securities need not
be executed and furnished until further notice from the Company. Until so exchanged, the temporary Securities of such series shall
be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.


 


Section 2.07
Mutilated, Destroyed, Lost or Stolen Securities.


 


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


 


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


 




    	 	-12-	 



     


    

 


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


 


Section 2.08
Cancellation.


 


All Securities surrendered
for the purpose of payment, redemption, 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 any legal or equitable right, remedy or claim under or in respect of this Indenture, or under
any covenant, condition or provision herein contained; all such covenants, conditions and provisions being for the sole benefit
of the parties hereto and of the holders of the Securities.


 


Section 2.10
Authenticating Agent.


 


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


 


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


 


Section 2.11
Global Securities.


 


(a) If
the Company shall establish pursuant to Section 2.01 that the Securities of a particular series are to be issued as a Global
Security, then the Company shall execute and the Trustee shall, in accordance with Section 2.04, authenticate and deliver,
a Global Security that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount
of, all of the Outstanding Securities of such series, (ii) shall be registered in the name of the Depositary or its nominee,
(iii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction 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.”


 




    	 	-13-	 



     


    

 


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


 


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


 


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.


 


(a) In
case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any series
in accordance with any right the Company reserved for itself to do so pursuant to Section 2.01 hereof, the Company shall,
or shall cause the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by mailing,
first class postage prepaid, 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 Officers’ Certificate
evidencing compliance with any such restriction.


  




    	 	-14-	 



     


    

 


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 designated for such purpose 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 for a sinking fund, if such is the case. If less than all the Securities of a series are to be redeemed,
the notice to the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be so
redeemed.


 


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


 


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


 


Section 3.03
Payment Upon Redemption.


 


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


 


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


 


Section 3.04
Sinking Fund.


 


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


 




    	 	-15-	 



     


    

 


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 Officers’ 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
Officers’ 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.

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

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 (such wire transfer to be made only to a Securityholder of an aggregate

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 Officers’ Certificate and delivered to the Trustee,
designate some other office or agency for such purposes or any of them. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, notices and demands. The Company initially appoints the Corporate Trust Office of the Trustee as
its paying agent with respect to the Securities.


 


Section 4.03
Paying Agents.


 


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


 


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


 


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


 


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


 


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


 


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

ARTICLE 6


 


REMEDIES OF
THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT


 


Section 6.01
Events of Default.


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 




    	 	-19-	 



     


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 




    	 	-20-	 



     


    

 


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


 


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


 


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


 


Section 6.03
Application of Moneys Collected.


 


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


 


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


 


SECOND: To the payment
of the amounts then due and unpaid upon Securities of such series for principal (and premium, if any) and interest, in respect

to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and


 


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


 


Section 6.04
Limitation on Suits.


 


No holder of any
Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless (i) such holder previously shall have given to the Trustee written notice
of an Event of Default and of the continuance thereof with respect to the Securities of such series specifying such Event of Default,
as hereinbefore provided; (ii) the holders of not less than 25% in aggregate principal amount of the Securities of such series
then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name
as Trustee hereunder; (iii) such holder or holders shall have offered to the Trustee 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.


 




    	 	-21-	 



     


    

 


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


 


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


 


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


 


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


 


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

Section 6.07
Undertaking to Pay Costs.


 


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


 


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


 


(b) No
provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:


 


(1) 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;


 


(2) 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;


 


(3) 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


 


(4) 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:


 


(a) 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;


 


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


 


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


 


(d) The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order
or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have
offered to the Trustee 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;


 


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


 


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


 


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


 


In addition, the
Trustee shall not be deemed to have knowledge of any Default or Event of Default except (1) any Event of Default occurring
pursuant to Sections 6.01(a)(1) and 6.01(a)(2) hereof or (2) any Default or Event of Default of which 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. 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 Officers’ Certificate).

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.

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

Moneys Held in Trust.


 


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


 


Section 7.06
Compensation and Reimbursement.


 


(a) The
Company 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.


 


(b) 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 additional indebtedness hereunder. 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.


 


Section 7.07
Reliance on Officers’ 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 Officers’ 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.

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


 


Section 7.09
Corporate Trustee Required; Eligibility.


 


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


 


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


 


Section 7.10
Resignation and Removal; Appointment of Successor.


 


(a) The
Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by giving
written notice thereof to the Company and by transmitting notice of resignation by mail, first class postage prepaid, to the Securityholders
of such series, as their names and addresses appear upon the Security Register.


 


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


 


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


 


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


 


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


 


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


 




    	 	-26-	 



     


    

 


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


 


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


 


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


 


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


 


Section 7.11
Acceptance of Appointment By Successor.


 


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


 


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


 




    	 	-27-	 



     


    

 


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


 


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


 


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


 


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


 


Any corporation
into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to 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 Default or
any Event of Default occurs and is continuing and if such Default or 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 Default or Event of Default within 45 days after it occurs, unless such Default or 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.


 




    	 	-28-	 



     


    

 


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


 


Section 8.02
Proof of Execution by Securityholders.


 


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


 


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


 


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


 


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


 


Section 8.03
Who May be Deemed Owners.


 


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


 




    	 	-29-	 



     


    

 


Section 8.05
Actions Binding on Future Securityholders.


 


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

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


 


It shall not be
necessary for the consent of the Securityholders of any series affected thereby under this Section to approve the particular form

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,

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.

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, may receive
an Officers’ Certificate or an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant
to this Article is authorized or permitted by, and conforms to, the terms of this Article and that it is proper for the Trustee
under the provisions of this Article to join in the execution thereof; provided, however, that such Officers’ 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 Trustee

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.
