and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

to hold such office prior to the authentication and delivery of such Securities or did not hold such office at the date of such Securities.

 

(c) 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 Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company
Order shall authenticate and deliver such Securities; provided, that, with respect to Securities of a series constituting a medium term

acceptable to the Trustee. The maturity dates, original issue dates, interest rates and any other terms of the Securities of such series
shall be determined by or pursuant to such Company Order and procedures.

 

    12

     

    

 

 

(d) If the form or terms of the Securities of the series have
been established in or pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such Securities,
and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel stating,

 

(1) if the form of any of such Securities has been established
by or pursuant to Board Resolution as permitted by Section 2.1, that such form has been established in conformity with the provisions
of this Indenture;

 

(2) if the terms of any of such Securities have been established
by or pursuant to Board Resolution as permitted by Section 3.1, that such terms have been established in conformity with the provisions
of this Indenture; and

 

(3) that such Securities, when authenticated and delivered by
the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute
valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization
and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles.

 

(e) Notwithstanding that such form or terms have been so established,
the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture would adversely
affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is
not reasonably acceptable to the Trustee.

 

(f) Notwithstanding the provisions of Section 3.1 and of
the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver
the Officer’s Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of Counsel otherwise
required pursuant to this Section 3.3 at or prior to the time of authentication of each Security of such series if such documents
have been delivered at or prior to the time of authentication upon original issuance of the first Security of such series to be issued.

 

(g) With respect to Securities of a series constituting a medium
term note program, if the form and general terms of the Securities of such series have been established by or pursuant to one or more
Board Resolutions or by an indenture supplemental hereto, as permitted by Sections 2.1 and 3.1, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, in addition to the foregoing documents and Opinion of Counsel,
or in lieu of clause (c) above, an Opinion of Counsel stating that the Securities have been duly authorized by the Company and, when
duly executed by the Company and completed and authenticated by the Trustee in accordance with the Indenture and issued, delivered and
paid for in accordance with any applicable distribution agreement, will have been duly issued under the Indenture and will constitute
valid and binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization
and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general equity principles.

 

(h) Each Security shall be dated the date of its authentication.

 

(i) No Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form
provided for herein executed by the Trustee by manual or facsimile signature, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits
of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9 together
with a written statement (which need not comply with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to
have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.4 Temporary Securities.

 

(a) Pending the preparation of definitive Securities of any series,
the Company may execute, and upon Company Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the Officer or Officers,
as the case may be, executing such Securities may determine, as evidenced by his, her or their execution of such Securities.

   

(b) If temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities
of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender
of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge
to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and, upon
Company Order, the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the
same series and of like tenor, of authorized denominations. Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities of such series.

 

Section 3.5 Registration; Registration of Transfer and Exchange.

 

(a) The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of
Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities.
The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities
as herein provided and “Paying Agent” for the Securities. In acting hereunder and in connection with the Securities, the Paying
Agent and Security Registrar shall act solely as agents of the Company, and will not thereby assume any obligations towards or relationship
of agency or trust for or with any Holder.

 

(b) Upon surrender for registration of transfer of any Security
of any series at an office or agency of the Company in a Place of Payment designated by the Company pursuant to Section 10.2 for
that series, the Company shall execute and, upon Company Order, the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal
amount and tenor.

 

(c) At the option of the Holder, Securities of any series may
be exchanged for other Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the
Company shall execute and, upon Company Order, the Trustee shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

 

(d) All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

 

(e) Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company) be duly endorsed, or be accompanied by a written instrument of transfer,
in form satisfactory to the Company and the Security Registrar, duly executed by the Holder thereof or such Holder’s attorney duly
authorized in writing.

 

(f) No service charge shall be made for any registration of transfer
or for exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4,
9.6 or 11.7 not involving any transfer.

 

(g) The Company shall not be required (i) to issue, register
the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the
sending of a notice of redemption of Securities of that series selected for redemption under Section 11.3 and ending at the close
of business on the day of such transmission, or (ii) to register the transfer of or exchange any Security so selected for redemption
in whole or in part, except the unredeemed portion of any Security being redeemed in part.

 

    14

     

    

 

 

 

(h) Notwithstanding the foregoing, any Global Security shall be
exchangeable pursuant to this Section 3.5 for Securities registered in the names of Persons 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 any time such Depositary ceases to be a clearing agency registered under the Exchange Act and the Company has not
appointed a successor Depositary within 90 days from the date of such notice or from the date the Company became aware that such Depositary
is no longer registered, as applicable, (ii) the Company executes and delivers to the Trustee a Company Order that such Global Security
shall be so exchangeable or (iii) there shall have occurred and be continuing an Event of Default of which the Trustee has been notified
with respect to the Securities and the Depositary for such Global Security requests such exchange in writing. 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.

 

(i) Notwithstanding any other provision in this Indenture, 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
or by a nominee of such Depositary to such Depositary or another nominee of such Depositary.

 

(j) The Trustee shall have no responsibility, obligation or duty
to:

 

(1) any beneficial owner of a Global Security, any member or participant
in the Depositary or any other Person with respect to (A) the accuracy of the records of the Depositary or its nominee or of any
participant or member thereof, with respect to any ownership interest in the Securities, (B) the delivery to any participant, member,
beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or purchase) or the payment
of any amount or delivery of any Securities (or other security or property) under or with respect to such Securities, or (C) the
selection of the particular Securities or portions thereof to be redeemed or refunded in the event of a partial redemption or refunding
of the Securities; or

 

(2) monitor, determine or inquire as to compliance with any restrictions
on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including
any transfers between or among the Depositary, its agent members or beneficial owners in any Global Security) other than to require delivery
of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by,
the terms of this Indenture with respect to transfers between Holders, and to examine the same to determine substantial compliance as
to form with the express requirements hereof. Neither the Trustee nor any of its agents shall have any responsibility for any actions
taken or not taken by the Depositary.

 

(3) All notices and communications to be given by any beneficial
owner of a Security and all payments to be made to any beneficial owner of a Security in respect of the Securities shall be given or made
only to or upon the order of the registered owner or owners of the Securities (which shall be the Depositary or its nominee in the case
of a Global Security). The rights of the beneficial owners of any Global Security shall be exercised only through the Depositary subject
to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information
furnished by the Depositary with respect to its members, participants and beneficial owners.

 

Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

 

(a) If any mutilated Security is surrendered to the Trustee, the
Company shall execute and, upon Company Order, the Trustee 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.

 

(b) 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 and/or indemnity
as may be required by them to save each of them and any agent of any 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, upon Company Order, the Trustee
shall authenticate and deliver, 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.

 

(c) 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.

 

    15

     

    

 

(d) Upon the issuance of any new Security under this Section 3.6,
the Company or the Trustee 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 reasonable fees and expenses of the Trustee and its counsel) connected therewith.

 

(e) Every new Security of any series issued pursuant to this Section 3.6
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.

 

(f) The provisions of this Section 3.6 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 3.7 Payment of Interest; Interest Rights Preserved.

 

(a) Unless otherwise provided as contemplated by Section 3.1
with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at
the close of business on the Regular Record Date for such interest.

 

(b) Any interest on any Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”)
shall forthwith cease to be payable to the Holder entitled to such interest by virtue of having been such Holder, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

 

(1) The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of
business on a Special Record Date (as defined below) 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 Security of such
series 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 Company shall fix a special record date (the “Special
Record Date”) for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days
prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment.
The Company shall promptly notify the Company of such Special Record Date and the Trustee, 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 sent to each Holder of
Securities of such series in accordance with Section 1.6, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been so sent, such Defaulted Interest shall be
paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

 

(2) The Company may make payment of any Defaulted Interest on
the Securities of any series 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.

 

(3) The Trustee will have no duty whatsoever to determine whether
any Defaulted Interest is payable or the amount thereof.

 

(c) Subject to the foregoing provisions of this Section 3.7,
each Security delivered under this Indenture, upon registration of transfer of or in exchange for or in lieu of any other Security shall
carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

 

    16

     

    

 

Section 3.8 Persons Deemed Owners.

 

Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 3.7)
interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. Without limiting the generality of the
foregoing, a Holder, including any Depositary that is the Holder of a Global Security, may make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture
to be made, given or taken by Holders, and the Depositary that is the Holder of a Global Security may provide its proxy or proxies to
the beneficial owners of interests in any such Global Security through such Depositary’s standing instructions and customary practice.

 

Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Security or shall
impair, as between such Depositary and owners of beneficial interests in such Global Security, the operation of customary practices governing
the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security.

 

Section 3.9 Cancellation.

 

All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which
the Company has not issued and sold and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.9, except as expressly permitted
by this Indenture. Subject to the record retention requirements of the Act and the Trustee’s procedures, all canceled Securities
held by the Trustee shall be disposed of as directed by a Company Order.

of such series and replacement of lost, stolen or mutilated Securities of such series herein expressly provided for), and the Trustee,
on the demand of and at the expense of the Company, shall execute instruments acknowledging satisfaction and discharge of this Indenture
with respect to such series, when

 

(1) either

 

(A) all Securities of such series theretofore authenticated and
delivered (other than (i) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid
as provided in Section 3.6 and (ii) Securities of such series for whose payment money has theretofore been deposited in trust
or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.3)
have been delivered to the Trustee for cancellation; or

 

    17

     

    

 

(B) all such Securities of such series not theretofore delivered
to the Trustee for cancellation

 

(i) have become due and payable, or

 

(ii) will become due and payable at their Stated Maturity within
one year, or

 

(iii) are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the Company, in the case of (i), (ii) or (iii), has irrevocably
deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and
discharge the entire indebtedness on such Securities of such series not theretofore delivered to the Trustee for cancellation, for principal
(and premium, if any) and interest to the date of such deposit (in the case of Securities of such series which have become due and payable)
or to the Stated Maturity or Redemption Date, as the case may be; and

 

(2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

 

(3) the Company has delivered to the Trustee an Officer’s
Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and

this Indenture shall upon Company Request cease to be of further effect and the Trustee, at the expense of the Company, shall execute
instruments of satisfaction and discharge of this Indenture.

 

(c) Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 6.7, the obligations of the Company to any Authenticating Agent under
Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of Section 4.1(a),
the obligations of the Trustee under Section 4.2 and the last paragraph of Section 10.3 shall survive.

 

Section 4.2 Application of Trust Money.

 

Subject to the provisions of the last paragraph of Section 10.3,
all money deposited with the Trustee pursuant to Section 4.1, all money and U.S. Government Obligations deposited with the Trustee

with the Trustee pursuant to Section 13.2 or Section 13.3, shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting
as Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for
whose payment such money has been deposited with or received by the Trustee as contemplated by Section 4.1, Section 13.2 or
Section 13.3.

specifically dealt with or which has expressly been included in this Indenture solely for the benefit of a series of Securities other
than the series in respect of which the Event of Default is being determined), and continuance of such default or breach for a period
of 60 days after there has been sent to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in
principal amount of the Outstanding Securities of that series, a written notice specifying such default or breach and requiring it to
be remedied and stating that such notice is a “Notice of Default” hereunder;

 

(e) the entry by a court having jurisdiction in the premises of

(f) the commencement by the Company of a voluntary case or proceeding
under any applicable bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated

the making by the Company of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to
pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or

 

(g) any other Event of Default provided with respect to Securities
of that series.

 

Section 5.2 Acceleration of Maturity; Rescission and Annulment.

 

(a) If an Event of Default (other than an Event of Default specified
in subsection (e) or (f) of Section 5.1) with respect to Securities of any series at the time Outstanding occurs and is
continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the entire principal amount (or, if any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in the terms thereof), together with accrued and unpaid interest,
if any, of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.
If an Event of Default specified in subsection (e) or (f) of Section 5.1 with respect to Securities of any series at the
time Outstanding occurs, the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such
portion of the principal amount of such Securities as may be specified in the terms thereof) of all of the Outstanding Securities of that
series shall be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security
of that series.

 

(b) At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter provided in this Article V, the Holders of a majority in principal amount of the Outstanding Securities of
that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

 

    19

     

    

 

(1) the Company has paid or deposited with the Trustee a sum sufficient
to pay

 

(A) all overdue interest on all Securities of that series,

 

(B) the principal of (and premium, if any, on) any Securities
of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed
therefor in such Securities,

 

(C) to the extent that payment of such interest is lawful, interest
upon overdue principal (and premium, if any) and overdue interest at the rate or rates prescribed therefor in such Securities, and

 

(D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

 

(2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 5.13.

 

(c) No such rescission shall affect any subsequent default or
impair any right consequent thereon.

 

(d) Upon receipt by the Trustee of any declaration of acceleration,
or rescission and annulment thereof, with respect to Securities of a series all or part of which is represented by a Global Security,
the Trustee shall establish a record date for determining Holders of Outstanding Securities of such series entitled to join in such declaration
of acceleration, or rescission and annulment, as the case may be, which record date shall be at the close of business on the day the Trustee
receives such declaration of acceleration, or rescission and annulment, as the case may be. The Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to join in such declaration of acceleration, or rescission and annulment,
as the case may be, whether or not such Holders remain Holders after such record date; provided, that unless such declaration of acceleration,
or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having been obtained
prior to the day which is 90 days after such record date, such declaration of acceleration, or rescission and annulment, as the case may
be, shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new declaration of acceleration, or rescission
or annulment thereof, as the case may be, that is identical to a declaration of acceleration, or rescission or annulment thereof, which
has been canceled pursuant to the preceding sentence, in which event a new record date shall be established pursuant to the provision
of this Section 5.2.

 

Section 5.3 Collection of Indebtedness and Suits for Enforcement
by Trustee.

 

(a) The Company covenants that if:

 

(1) 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

 

(2) default is made in the payment of the principal of (or premium,
if any, on) any Security at the Maturity thereof; or

 

(3) 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 premium, if any) and interest and, to the
extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on 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 the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

 

    20

     

    

 

(b) If the Company fails to pay such amounts forthwith 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 decreed 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.

 

(c) If an Event of Default with respect to 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 such appropriate judicial proceedings 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.

 

Section 5.4 Trustee May File Proofs of Claim.

 

(a) In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor
upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company for the payment of overdue principal (and premium, if any) or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

 

(1) to file and prove a claim for the whole amount of principal
(and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

 

(2) to collect and receive any moneys or other property payable
or deliverable on any such claims and to distribute the same.

 

(b) Any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due
it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 6.7.

 

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

 

(d) The Trustee shall be entitled to participate as a member of
any official committee of creditors in the matters it deems advisable.

 

Section 5.5 Trustee May Enforce Claims Without Possession
of Securities.

 

All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding
relating thereto, and any such 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 the payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has
been recovered.

 

Section 5.6 Application of Money Collected.

 

Any money or property collected by the Trustee pursuant to this Article V
or, after an Event of Default, any money or other property distributable in respect of the Company’s obligations under this Indenture
shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money or property
on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

 

    21

     

    

 

FIRST: To the payment of all amounts due the Trustee (including any
predecessor trustee) under Section 6.7;

 

SECOND: To the payment of the amounts then due and unpaid for principal
of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium,
if any) and interest, respectively; and

 

THIRD: To the Company.

 

Section 5.7 Limitation on Suits.

 

No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

 

(a) such Holder has previously given written notice to the Trustee
of a continuing Event of Default with respect to the Securities of that series;

 

(b) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event
of Default in its own name as Trustee hereunder;

 

(c) such Holder or Holders have offered to the Trustee indemnity
and/or security satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

 

(d) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity and/or security has failed to institute any such proceeding; and

 

(e) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that
series;

 

it being understood and intended that no one or more of such Holders
shall have any right in any manner whatever by virtue of any provision of this Indenture to affect, disturb or prejudice the rights of
any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders (it being understood
that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances affect, disturb or prejudice
the rights of, or seek to obtain priority or preference over, such Holders) or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such Holders.

 

Section 5.8 Unconditional Right of Holders to Receive Principal,
Premium and Interest.

 

Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and
interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such
Holder.

 

Section 5.9 Restoration of Rights and Remedies.

 

If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company,
the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

 

    22

     

    

 

Section 5.10 Rights and Remedies Cumulative.

 

Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

 

Section 5.11 Delay or Omission Not Waiver.

 

No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

 

Section 5.12 Control by Holders.

 

(a) The Holders of a majority in principal amount of the Outstanding
Securities of any series 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 the Securities of such series, provided
that,

 

(1) such direction shall not be in conflict with any rule of
law or with this Indenture, nor subject the Trustee to a risk of personal liability in respect of which the Trustee has not received indemnification
satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by taking or not taking such action, and

 

(2) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

 

(b) Prior to taking any such action hereunder, the Trustee shall
be entitled to indemnification and/or security satisfactory to it in its sole discretion against all fees, losses, liabilities and expenses
(including attorney’s fees and expenses) caused by or that might be caused by taking or not taking such action.

 

(c) Upon receipt by the Trustee of any such direction with respect
to Securities of a series all or part of which is represented by a Global Security, the Trustee may establish a record date for determining
Holders of Outstanding Securities of such series entitled to join in such direction, which record date shall be at the close of business
on the day the Trustee receives such direction. The Holders on such record date, or their duly designated proxies, and only such Persons,
shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided, that unless
such majority in principal amount shall have been obtained prior to the day which is 90 days after such record date, such direction shall
automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new direction identical to a direction which has
been canceled pursuant to the provisions to the preceding sentence, in which event a new record date shall be established pursuant to
the provisions of this Section 5.12.

 

Section 5.13 Waiver of Past Defaults.

 

(a) The Holders of not less than a majority in principal amount
of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder
with respect to such series and its consequences, except a default:

 

(1) in the payment of the principal of (or premium, if any) or
interest on any Security of such series which have become due otherwise than by a declaration of acceleration under Section 5.2 and
interest thereon at the rate or rates prescribed therefor in such Securities, or

 

    23

     

    

 

(2) in respect of a covenant or provision hereof which under Article IX
cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

 

(b) Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other default or impair any right consequent thereon.

 

Section 5.14 Undertaking for Costs.

 

Each party to this Indenture agrees, and each Holder of any Security
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, suffered 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 5.14
shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or
group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or
after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

 

Section 5.15 Waiver of Usury, Stay or Extension Laws.

 

The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay
or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture;
and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants
that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution
of every such power as though no such law had been enacted.

 

ARTICLE VI

 

THE TRUSTEE

 

Section 6.1 Certain Duties and Responsibilities.

 

(a) Except during the continuance of an Event of Default,

 

(1) the Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against
the Trustee; and

 

(2) in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon 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 which 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 (but need not confirm or investigate the accuracy or mathematical calculations
or other facts, statements, opinions or conclusions stated therein).

 

    24

     

    

 

(b) In case an Event of Default has occurred and is continuing,
the Trustee shall exercise 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 person would exercise or use under the circumstances in the conduct of such person’s own affairs.

 

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

 

(1) this subsection shall not be construed to limit the effect
of subsections (a) or (d) of this Section 6.1;

 

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

 

(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, determined as provided in Section 5.12, of the
Holders of a majority in principal amount of the Outstanding Securities of any series, 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 such series.

 

(d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have grounds for believing that repayment of such funds or adequate indemnity and/or security
against such risk or liability is not assured to it.

 

(e) Whether or not therein expressly so provided, every provision
of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 6.1.

 

Section 6.2 Notice of Defaults.

 

Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall send to all Holders of Securities of such series notice of such default hereunder known
to the Trustee (as set forth in Section 6.3(o)), unless such default shall have been cured or waived; 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 of such series
or in the payment of any sinking fund installment with respect to Securities of such series, 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 or Responsible Officers
of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of Securities of such series.
For the purpose of this Section 6.2, the term “default” means any event which is, or after notice or lapse
of time or both would become, an Event of Default with respect to Securities of such series.

 

Section 6.3 Certain Rights of Trustee.

 

Subject to the provisions of Section 6.1:

 

(a) the Trustee may conclusively rely and shall be fully protected
in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness 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 or direction of the Company mentioned herein shall
be sufficiently evidenced by a Company Request or Company Order, or as otherwise expressly provided herein, and any resolution of the
Board of Directors may be sufficiently evidenced by a Board Resolution;

 

    25

     

    

 

(c) whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee
(unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officer’s
Certificate;

 

(d) before the Trustee acts or refrains from acting, it may require
an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection
and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

 

(e) the Trustee shall be under no obligation to exercise any of

(b) to reimburse the Trustee upon its request for all reasonable
out-of-pocket expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture
(including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in

determined by a court of appropriate jurisdiction in a final, non-appealable judgment; and

 

(c) to indemnify the Trustee, any predecessor Trustee and their
respective agents, directors, employees and officers for, and to hold them harmless against, any loss, damage, claim, liability or out-of-pocket
expense (including the reasonable compensation and the expenses and disbursements of its agents and counsel, court costs and taxes (other

trust or trusts hereunder, including the reasonable costs and out-of-pocket expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of the Trustee’s powers or duties hereunder, or in connection with enforcing

    27

     

    

 

The Trustee shall notify the Company promptly of any claim for which
it may seek indemnification pursuant to the provisions of this Indenture. Failure by the Trustee to so notify the Company shall not relieve
the Company of its obligations hereunder. The Company shall be entitled to participate in, and to the extent that it shall wish, to assume
the defense of such claim, with counsel satisfactory to the Trustee (and the Trustee shall cooperate in the defense thereof). The Trustee
may employ separate counsel at the expense of the Company. Any settlement which affects the Trustee may not be entered into without the
consent of the Trustee. After the Company has assumed the defense of any indemnified party hereunder, no such indemnified party may settle
or compromise any suit or action without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or
delayed).

 

As security for the performance of the obligations of the Company under
this Section 6.7, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee

Section 5.1(f), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services

Company hereunder, shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination
of this Indenture for any reason.

 

Section 6.8 Disqualification; Conflicting Interests.

 

The Trustee shall comply with the terms of Section 310(b) of

Section 6.9 Corporate Trustee Required; Eligibility.

 

There shall at all times be a Trustee hereunder which shall be eligible
to act as such pursuant to the Trust Indenture Act and which shall be a corporation organized and doing business under the laws of the
United States of America, any state thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state authority.
If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section 6.9, the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section 6.9, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VI.

 

Section 6.10 Resignation and Removal; Appointment of Successor.

 

(a) No resignation or removal of the Trustee and no appointment
of a successor Trustee pursuant to this Article VI shall become effective until the acceptance of appointment by the successor Trustee
in accordance with the applicable requirements of Section 6.11.

 

(b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required
by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

 

(c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered
to the Trustee and to the Company not less than 30 days prior to the effective date of such removal.

 

(d) If at any time:

 

    28

     

    

 

(1) the Trustee shall fail to comply with Section 6.8 after
written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months;

 

(2) the Trustee shall cease to be eligible under Section 6.9
and shall fail to resign after written request therefor by the Company or by any such Holder; or

 

(3) the Trustee shall become incapable of acting or shall be adjudged
a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed 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, (i) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (ii) subject to Section 5.14,
any Holder who has been a bona fide Holder of a Security for at least six months may, on its own behalf and on behalf of all others similarly
situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment
of a successor Trustee or Trustees.

 

(e) If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such
series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply
with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or incapability, or the occurrence
of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee
so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11,
become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed
by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the
Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security
of such series for at least six months may, on its own behalf and on behalf of all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 

(f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities
of any series by sending written notice of such event to all Holders of Securities of such series in the manner provided in Section 1.6.
Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate
Trust Office.

 

(g) Notwithstanding replacement of the Trustee pursuant to this
Section 6.10, the Company’s obligations under Section 6.7 hereof shall continue for the benefit of the retiring Trustee.

 

(h) The resigning Trustee shall have no responsibility or liability
for any action or inaction of a successor Trustee.

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

 

    29

     

    

 

(b) In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with
respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee
shall accept such appointment and which (1) 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; (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee; and (3) shall add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood
that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and, 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 and each such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

 

(c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers
and trusts referred to in paragraph (a) and (b) of this Section 6.11, as the case may be.

 

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

 

Section 6.12 Merger, Conversion, Consolidation or Succession
to Business.

 

Any Person into which the Trustee may be merged or converted or with
which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party,
or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such Person shall be otherwise qualified and eligible under this Article VI, without the execution or filing
of any paper or any further act on the part of any of the parties hereto. 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 6.13 Preferential Collection of Claims.

 

The Trustee shall comply with Section 311(a) of the Trust
Indenture Act, excluding any creditor relationship listed 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 indicated therein.

 

Section 6.14 Appointment of Authenticating Agent.

 

(a) At any time when any of the Securities remain Outstanding,
the Trustee may, and upon request of the Company, shall, appoint an Authenticating Agent(s) with respect to one or more series of
Securities, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section 3.6. 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. Wherever
reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate
of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall
be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States
of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such Authenticating
Agent publishes reports of condition at least annually pursuant to law or to the requirements of said supervising or examining authority,
then for the purposes of this Section 6.14, the combined capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section 6.14, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section 6.14.

 

    30

     

    

 

(b) Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of
an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this
Section 6.14, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

 

(c) An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent and the Company, and the Trustee shall terminate any such agency promptly upon request by
the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section 6.14, the Trustee may and, upon request of the Company,
shall appoint a successor Authenticating Agent which shall be acceptable to the Company and shall send written notice in the manner provided
in Section 1.6 of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will
serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers
and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section 6.14.

 

(d) The Company agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section 6.14.

 

(e) If an appointment of an Authenticating Agent with respect
to one or more series is made pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in lieu of
the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

 

This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

	 	 	as Authenticating Agent
	 	 	 
	 	By	 
	 	 	Authorized Signatory

 

Section 6.15 FATCA.

 

Notwithstanding any other provision of this Indenture, the Trustee
shall be entitled to make a deduction or withholding from any payment which it makes under this Indenture for or on account of any present
or future taxes, duties or charges if and to the extent so required by any applicable law and any current or future regulations or agreements
thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto or by virtue of the relevant
Holder failing to satisfy any certification or other requirements in respect of the Securities, in which event the Trustee shall make
such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld
or deducted and shall have no obligation to gross up any payment hereunder or pay any additional amount as a result of such withholding
tax.

 

The Company hereby covenants with the Trustee that it will provide
the Trustee with sufficient information so as to enable the Trustee to determine whether or not the Trustee is obliged, in respect of
any payments to be made by it pursuant to this Indenture, to make any withholding or deduction pursuant to an agreement described in Section 1471(b) of
the US Internal Revenue Code of 1986, as amended (the “Code”) or otherwise imposed pursuant to Sections 1471
through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof or any intergovernmental agreement
between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental
agreement).

(i) in the case of an election under Section 13.3, the Company

income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not
occurred;

 

(j) such defeasance or covenant defeasance shall be effected in

Section 13.5 Deposited Money and U.S. Government Obligations
to Be Held in Trust; Other Miscellaneous Provisions.

 

(a) Subject to the provisions of the last paragraph of Section 10.3,
all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively,
for purposes of this Section 13.5, the “Trustee”) pursuant to Section 13.4 in respect of the Outstanding
Securities of such series shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and
this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own paying agent), to
the Holders of such Securities, of all sums due and to become due thereon in respect of principal (and premium, if any) and interest,
but such money need not be segregated from other funds except to the extent required by law.

 

(b) The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 13.4 or the
principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the
Holders of the Outstanding Securities of such series.

 

(c) Anything in this Article XIII to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by
it as provided in Section 13.4 which, in the opinion of a nationally recognized firm of independent public accountants, investment
bank or appraisal firm expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

 

(d) In the event that the Trustee is unable to apply the funds
held in trust to the payment of obligations under the Securities by reason of a court order or governmental injunction or prohibition,
then those of the Company’s obligations discharged under the defeasance or covenant defeasance will be revived and reinstated as
though no deposit of funds had occurred, until such time as the Trustee is permitted to apply all funds held in trust under the procedure
described above to the payment of obligations under the Securities. However, if the Company makes any payment of principal or interest
the Holders, the Company will have the right to receive such payments from the trust in the place of the Holders.
