2.3         Execution and Authentication


 


Two Officers shall sign the Securities for the
Company by manual or facsimile signature.


 


If an Officer whose signature is on a Security
no longer holds that office at the time the Security is authenticated, the Security shall nevertheless be valid.


 


A Security shall not be valid until authenticated
by the manual or facsimile signature of the Trustee or an authenticating agent. The signature shall be conclusive evidence that the Security
has been authenticated under this Indenture.


 


The Trustee shall at any time, and from time
to time, authenticate Securities for original issue in the principal amount provided in the Board Resolution, supplemental indenture hereto
or Officers’ Certificate, upon receipt by the Trustee of a Company Order. Each Security shall be dated the date of its authentication
unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate.


 






    -8-


     


    

 


The aggregate principal amount of Securities
of any Series outstanding at any time may not exceed any limit upon the maximum principal amount for such Series set forth in the Board
Resolution, supplemental indenture hereto or Officers’ Certificate delivered pursuant to Section 2.2, except as provided in Section
2.8.


 


Prior to the issuance of Securities of any Series,
the Trustee shall have received and (subject to Section 7.2) shall be fully protected in relying on: (a) the Board Resolution, supplemental
indenture hereto or Officers’ Certificate establishing the form of the Securities of that Series or of Securities within that Series
and the terms of the Securities of that Series or of Securities within that Series, (b) an Officers’ Certificate complying with
Section 10.4, and (c) an Opinion of Counsel complying with Section 10.4.


 


The Trustee shall have the right to decline to
authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised by counsel, determines that such action may
not be taken lawfully; or (b) if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee
of directors and/or vice-presidents shall determine that such action would expose the Trustee to personal liability to Holders of any
then outstanding Series of Securities.


 


The Trustee may appoint an authenticating agent
acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has
the same rights as an Agent to deal with the Company or an Affiliate of the Company.


 


Section
2.4          Registrar and Paying Agent


 


Company shall maintain, with respect to each
Series of Securities, at the place or places specified with respect to such Series pursuant to Section 2.2, an office or agency where
Securities of such Series may be presented or surrendered for payment (“Paying Agent”), where Securities of such Series may
be surrendered for registration of transfer or exchange, where Securities of such Series that are convertible or exchangeable may be surrendered
for conversion or exchange, as applicable, where Securities of such Series may be surrendered for conversion or exchange (“Registrar”)
and where notices and demands to or upon the Company in respect of the Securities of such Series and this Indenture may be delivered (“Notice
Agent”). The Trustee or Notice Agent, as applicable, shall deliver such notices and demands to the Company in accordance with Section
10.2 hereof. The Registrar shall keep a register with respect to each Series of Securities and to their transfer and exchange. The Company
will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar, Paying
Agent or Notice Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying Agent or Notice Agent or
shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or
delivered at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.


 






    -9-


     


    

 


The Company hereby appoints the Trustee the initial
Registrar, Paying Agent and Notice Agent for each Series unless another Registrar, Paying Agent or Notice Agent, as the case may be, is
appointed prior to the time Securities of that Series are first issued.


 


The Company hereby appoints The Depository Trust
Company to act as Depositary with respect to the Securities.


 


Section
2.5        Paying Agent to Hold Money in Trust The
Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the benefit
of Security Holders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or
interest on the Series of Securities, and will notify the Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts
as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of Security Holders of any Series of Securities
all money held by it as Paying Agent.


 


Section
2.6         Securityholder Lists


 


The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of Security Holders of each Series of Securities
and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least
ten days before each interest payment date and at such other times as the Trustee may request in writing a list, in such form and as of
such date as the Trustee may reasonably require, of the names and addresses of Security Holders of each Series of Securities.


 


Section
2.7         Transfer and Exchange


 


Where Securities of a Series are presented to
the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Securities
of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met.
To permit registrations of transfers and exchanges, the Trustee shall authenticate Securities upon receipt of a Company Order. No service
charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may
require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than
any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.11, 3.6 or 9.6).


 


Neither the Company nor the Registrar shall
be required (a) to issue, register the transfer of, or exchange Securities of any Series for the period beginning at the opening of
business fifteen days immediately preceding the mailing of a notice of redemption of Securities of that Series selected for
redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange Securities
of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities
selected, called or being called for redemption in part.

Section
2.8         Mutilated, Destroyed, Lost and Stolen Securities If
any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee, upon receipt of a Company Order, shall
authenticate and deliver in exchange therefor a new Security of the same Series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.


 


If there shall be delivered to the Company and
the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as
may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or
the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee, upon receipt of
a Company Order, shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.


 


In case any such mutilated, destroyed, lost or
stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security,
pay such Security.


 


Upon the issuance of any new Security under this
Section, 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.


 


Every new Security of any Series issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the
Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all other Securities of that Series duly issued hereunder.


 


The provisions of this Section are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities.


 


Section
2.9         Outstanding Securities


 


The Securities outstanding at any time are all
the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions
in the interest on a Global Security effected by the Trustee in accordance with the provisions hereof and those described in this Section as
not outstanding.


 


If a Security is replaced pursuant to Section 2.8,
it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.


 


If the Paying Agent (other than the Company,
a Subsidiary of the Company or an Affiliate of the Company) holds on the Maturity of Securities of a Series money sufficient to pay
such Securities payable on that date, then on and after that date such Securities of the Series cease to be outstanding and interest
on them ceases to accrue.


 






    -11-


     


    

 


A Security does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Security.


 


In determining whether the Holders of the requisite
principal amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder,
the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the amount of the principal
thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof
pursuant to Section 6.2.


 


Section
2.10       Treasury Securities


 


In determining whether the Holders of the required
principal amount of Securities of a Series have concurred in any request, demand, authorization, direction, notice, consent or waiver,
Securities of a Series owned by the Company or any Affiliate of the Company shall be disregarded, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such request, demand, authorization, direction, notice, consent or waiver only
Securities of a Series that the Trustee knows are so owned shall be so disregarded.


 


Section
2.11      Temporary Securities Until
definitive Securities are ready for delivery, the Company may prepare and the Trustee, upon receipt of a Company Order, shall authenticate
temporary Securities upon a Company Order. Temporary Securities shall be substantially in the form of definitive Securities but may have
variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee, upon receipt of a Company Order, shall authenticate definitive Securities of the same Series and date of maturity in exchange
for temporary Securities. Until so exchanged, temporary securities shall have the same rights under this Indenture as the definitive
Securities.


 


Section
2.12        Cancellation


 


The Company at any time may deliver Securities
to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for
registration of transfer, exchange or payment. Upon receipt of written instruction from the Company, the Trustee shall cancel all Securities
surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy such canceled Securities and deliver a certificate
of such destruction to the Company, unless the Company otherwise directs. The Company may not issue new Securities to replace Securities
that it has paid or delivered to the Trustee for cancellation.


 


Section 2.13      
Defaulted Interest


 


If the Company defaults in a payment of interest
on a Series of Securities, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted
interest, to the persons who are Security Holders of the Series on a subsequent special record date. The Company shall fix the record
date and payment date. At least 10 days before the record date, the Company shall mail to the Trustee and to each Security Holder of the
Series a notice that states the record date, the payment date and the amount of interest to be paid. The Company may pay defaulted interest
in any other lawful manner.

2.14.1.    Terms

of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such Global Security
or Securities.


 


2.14.2.    Transfer
and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.7 of the Indenture and in addition thereto, any
Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders other
than the Depositary for such Security or its nominee only if (i) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the
Exchange Act, and, in either case, the Company fails to appoint a successor Depositary registered as a clearing agency under the Exchange
Act within 90 days of such event or (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect
that such


 


Global Security shall be so exchangeable. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the
Depositary shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor
and terms.


 


Except as provided in this Section 2.14.2, a Global
Security may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary,
by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such a successor Depositary.


 


The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security other than to require delivery of such certificates and other documentation
or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine
the same to determine substantial compliance as to form with the express requirements hereof.


 


2.14.3.    Legend.
Any Global Security issued hereunder shall bear a legend in substantially the following form:


 


“THIS SECURITY IS A GLOBAL SECURITY WITHIN
THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE OF THE DEPOSITARY. THIS
SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED
CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY,

DEPOSITARY OR A NOMINEE OF SUCH A SUCCESSOR DEPOSITARY.”

required to be given by the Holders pursuant to this Indenture.


 


Section
2.15       CUSIP Numbers


 


The Company in issuing the Securities may use
 “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption
as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the
other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission
of such numbers.

Section
6.3         Collection of Indebtedness and Suits for Enforcement by
Trustee


 


The Company covenants that if

default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues
for a period of 30 days, or


 


(b)      
default is made in the payment of principal of any Security at the Maturity thereof, or


 


(c)      
default is made in the deposit of any sinking fund payment, when and as due by the terms of a Security,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection
of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company
or any other obligor upon such Securities and collect the moneys adjudged or deemed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever situated.

Indenture, if an Event of Default with respect to any Securities of any Series occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such Series by pursuing any
available remedy by proceeding at law or in equity as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

such Officers’ Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the

the Company and those of the Trustee. The Trustee may have one separate counsel (in addition to local counsel, if applicable) and

The Company and the Trustee may enter into
a supplemental indenture with the written consent of the Holders of at least a majority in principal amount of the outstanding
Securities of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer or
exchange offer for the Securities of such Series), 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 the rights of the
Security Holders of each such Series. Except as provided in Section 6.13, the Holders of at least a majority in principal amount of
the outstanding Securities of any Series by notice to the Trustee (including consents obtained in connection with a tender offer or
exchange offer for the Securities of such Series) may waive compliance by the Company with any provision of this Indenture or the
Securities with respect to such Series.


 


It shall not be necessary for the consent of
the Holders of Securities under this Section 9.2 to approve the particular form of any proposed supplemental indenture or waiver, but
it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this section becomes
effective, the Company shall mail to the Holders of Securities affected thereby, a notice briefly describing the supplemental indenture
or waiver. Any failure by the Company to mail or publish such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture or waiver.


 


Section
9.3            Limitations


 


Without the consent of each Security Holder affected,
an amendment or waiver may not:


 


(a)              
reduce the principal amount of Securities whose Holders must consent to an amendment, supplement or waiver;


 


(b)              
reduce the rate of or extend the time for payment of interest (including default interest) on any Security;


 


(c)              
reduce the principal or change the Stated Maturity of any Security or reduce the amount of, or postpone the date fixed for, the

waive a Default or Event of Default in the payment of the principal of or interest, if any, on any Security (except a rescission
of acceleration of the Securities of any Series by the Holders of at least a majority in principal amount of the outstanding Securities
of such Series and a waiver of the payment default that resulted from such acceleration);


 


(f)               
make the principal of or interest, if any, on any Security payable in any currency other than that stated in the Security;

Section
9.5            Revocation and Effect of Consents


 


Until an amendment is set forth in a supplemental
indenture or a waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation
of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or
portion of a Security if the Trustee receives the notice of revocation before the date of the supplemental indenture or the date the waiver
becomes effective.


 


Any amendment or waiver once effective shall
bind every Security Holder of each Series affected by such amendment or waiver unless it is of the type described in any of clauses (a)
through (h) of Section 9.3. In that case, the amendment or waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.


 


Section
9.6            Notation on or Exchange of Securities


 


The Trustee may place an appropriate notation
about an amendment or waiver on any Security of any Series thereafter authenticated. The Company in exchange for Securities of that Series
may issue and the Trustee shall authenticate upon receipt of a Company Order new Securities of that Series that reflect the amendment
or waiver.


 


Section
9.7            Trustee Protected 


 


In executing, or accepting the additional trusts
created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture,

10.14    Securities in a Foreign Currency or ECU


 


Unless otherwise specified in a Board

with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders of
a specified percentage in aggregate principal amount of Securities of all Series or all Series affected by a particular action at

the sum due in respect of the principal of or interest or other amount on the Securities of any Series (the “Required Currency”)

ARTICLE
XI


SINKING FUNDS


 


Section
11.1        Applicability of Article


 


The provisions of this Article shall be
applicable to any sinking fund for the retirement of the Securities of a Series, except as otherwise permitted or required by any form
of Security of such Series issued pursuant to this Indenture.


 


The minimum amount of any sinking fund payment
provided for by the terms of the Securities of any Series is herein referred to as a “mandatory sinking fund payment”
and any other amount provided for by the terms of Securities of such 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 11.2. Each sinking fund payment shall be applied to the redemption of Securities of any Series
as provided for by the terms of the Securities of such Series.


 


Section
11.2        Satisfaction of Sinking Fund Payments with Securities


 


The Company may, in satisfaction of all or any
part of any sinking fund payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (1)
deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than any of such Securities previously
called for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to which such sinking fund payment is
applicable and which have been repurchased by the Company or redeemed either at the election of the Company pursuant to the terms of such
Series of Securities (except pursuant to any mandatory sinking fund) or through the application of permitted optional sinking fund payments
or other optional redemptions pursuant to the terms of such Securities, provided that such Securities have not been previously so credited.
Such Securities shall be received by the Trustee, together with an Officers’ Certificate with respect thereto, not later than 15
days prior to the date on which the Trustee begins the process of selecting Securities for redemption, and shall be credited for such
purpose by the Trustee at the 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. If as a result of the delivery or credit of Securities in lieu of cash payments
pursuant to this Section 11.2, the principal amount of Securities of such Series to be redeemed in order to exhaust the aforesaid cash
payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon receipt of a Company
Order that such action be taken, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding
sinking fund payment, provided, however, that the Trustee or such Paying Agent shall from time to time upon receipt of a
Company Order pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by
the Company to the Trustee of Securities of that Series purchased by the Company having an unpaid principal amount equal to the cash payment
required to be released to the Company.

Section 11.3       
Redemption of Securities for Sinking Fund 


 


Not less than 45 days (unless otherwise indicated
in the Board Resolution, supplemental indenture hereto or Officers’ Certificate in respect of a particular Series of Securities)
prior to each sinking fund payment date for any Series of Securities, the Company will deliver to the Trustee an Officers’
Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that Series pursuant to the terms of that
Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied
by delivering and crediting of Securities of that Series pursuant to Section 11.2, and the optional amount, if any, to be added
in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be obligated to pay the amount therein specified. 
Not less than 30 days (unless otherwise indicated in the Board Resolution, Officers’ Certificate or supplemental indenture in respect
of a particular Series of Securities) 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 3.2 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 3.3.  Such notice having been duly given,
the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 3.4, 3.5 and 3.6.
