and they may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed
or engraved thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Indenture, or as may be
required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities
exchange on which Securities of that series may be listed, or to conform to usage.


 


Section 2.3 Denominations:
Provisions for Payment.


 


The Securities shall be issuable
as registered Securities and in the denominations of one thousand U.S. dollars ($1,000) or any integral multiple thereof, subject to Section 2.01(a)(10).


 


The Securities of a particular
series shall bear interest payable on the dates and at the rate specified with respect to that series. Subject to Section 2.01(a)(16),
the principal of and the interest on the Securities of any series, as well as any premium thereon in case of redemption thereof prior
to maturity, shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and
private debt, at the office or agency of the Company maintained for that purpose. Each Security shall be dated the date of its authentication.
Interest on the Securities shall be computed on the basis of a 360-day year composed of twelve 30-day months.


 


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


 


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


 


(i) 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 fifteen (15) nor less than ten (10) days prior to the date of the proposed payment
and not less than ten (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 ten (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.


 


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


 


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


 


Section 2.4 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 2.5 Registration of
Transfer and Exchange.


 


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


 


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


 






    -7-


     


    

 


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.


 


(c) Except as provided
pursuant to Section 2.01 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or established in one or
more indentures supplemental to this Indenture, no service charge shall be made for any exchange or registration of transfer of Securities,
or issue of new Securities in case of partial redemption of any series, 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
fifteen (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 2.6 Temporary Securities.


 


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


 


Section 2.7 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.


 






    -8-


     


    

 


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 2.8 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 2.9 Benefits of Indenture.


 


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


 


Section 2.10 Authenticating
Agent.


 


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


 


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

Section 2.11 Global Securities.


 


(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.”


 


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


 


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

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS


 


Section 3.1 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.


 






    -10-


     


    

 


Section 3.2 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 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.


 


(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 3.3
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).


 






    -11-


     


    

 


(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 3.4
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 3.5 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 3.6 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.

(15) days prior to the relevant payment date.

Section 4.2 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 4.3 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:


 


(i) 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;


 


(ii) 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;


 


(iii) 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


 


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


 


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


 


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

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 VI


 


REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
ON EVENT OF DEFAULT


 


Section 6.1 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:


 


(i) 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 ninety (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;


 


(ii) 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;


 


(iii) 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 ninety (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;


 


(iv) 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


 


(v) 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 ninety (90) days.


 






    -15-


     


    

 


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


 


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


 


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


 


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


 


Section 6.2 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 ninety (90) days, or (ii) in case it shall default in the payment of the principal
of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of
the Securities of a series or upon redemption or upon declaration or otherwise then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall have been become due
and payable on all such Securities for principal (and premium, if any) or interest, or both, as the case may be, with interest upon the
overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable law) upon overdue
installments of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under Section 7.06.


 


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


 






    -16-


     


    

 


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


 


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


 


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


 


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


 


Section 6.3 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 Article Fourteen;


 


SECOND: To the payment of

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


 


Section 6.4 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 ninety (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 ninety (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.


 






    -17-


     


    

 


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 6.5 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 6.6
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 6.7 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 VII


 


CONCERNING THE TRUSTEE


 


Section 7.1 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


 






    -19-


     


    

 


(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 7.2 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, if requested, any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken or suffered or omitted hereunder in good faith and in reliance thereon;


 


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

of the same.


 


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

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 7.4 May Hold Securities.


 


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


 


Section 7.5 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 7.6 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 indebtedness of the Company to which the Securities are subordinated. Such additional indebtedness

funds held in trust for the benefit of the holders of particular Securities.


 


Section 7.7
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.

and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.


 


Section 7.9
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 thirty (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 (6)
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:


 


(1) 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


 


(2) 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


 


(3) 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 (6) 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.

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

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

for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such

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

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.

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 the earlier of ninety (90) days after it occurs and thirty (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 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 VIII


 


CONCERNING THE SECURITYHOLDERS


 


Section 8.1 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.


 






    -24-


     


    

 


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


 


Section 8.2 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 8.3 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 8.4 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 8.5 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.

In addition to any supplemental
indenture otherwise authorized by this Indenture, the Company 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), without the consent

such covenants, restrictions, conditions or provisions are expressly being included solely for the benefit of such series), to make the
occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions
an Event of Default, or to surrender any right or power herein conferred upon the Company;


 


(e) to add to, delete
from, or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication, and
delivery of Securities, as herein set forth;


 


(f) to make any change
that does not adversely affect the rights of any Securityholder in any material respect;


 


(g) to provide for the
issuance of and establish the form and terms and conditions of the Securities of any series as provided in Section 2.01, to establish
the form of any certifications required to be furnished pursuant to the terms of this Indenture or any series of Securities, or to add
to the rights of the holders of any series of Securities;


 


(h) to evidence and
provide for the acceptance of appointment hereunder by a successor trustee; or


 


(i) to comply with any
requirements of the Securities and Exchange Commission or any successor in connection with the qualification of this Indenture under the
Trust Indenture Act.


 


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.


 






    -26-


     


    

 


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 9.2 Supplemental Indentures
With Consent of Securityholders.


 


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


 


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


 


Section 9.3 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 9.4 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 9.5 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 Officer’s Certificate or, if requested, 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 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.


 






    -27-


     


    

 


Promptly after the execution
by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Trustee shall 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 Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

supplemental to this Indenture, 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

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.

same effect as if it had been named as the Company herein, and thereupon the predecessor corporation shall be relieved of all obligations
and covenants under this Indenture and the Securities.


 


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

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).

of this Article.
