any and all other terms with respect to the series (which terms shall not be inconsistent with the terms of this Indenture, as
amended by any Board Resolution or supplemental indenture, but which may modify or delete any provisions of this Indenture insofar as
it applies to such series), including any terms which may be required by or advisable under the applicable laws of the U.S. or regulations
thereunder or advisable (as determined by the Company) in connection with the marketing of Securities of that series.


All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant to any such Board Resolution or in any indentures supplemental
hereto.


If any of the terms of the series are established by action taken
pursuant to a Board Resolution of the Company, a copy of an appropriate record of such action shall be certified by the secretary or an
assistant secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate of the
Company setting forth the terms of the series.


Securities of any particular series may be issued at various times,
with different dates on which the principal or any installment of principal is payable, with different rates of interest, if any, or different
methods by which rates of interest may be determined, with different dates on which such interest may be payable and with different redemption
dates. A series may be reopened for issuances of additional Securities of such series or to establish additional terms of such Securities.

Section
2.2 Form of Securities and Trustee’s Certificate.


The Securities of any series and the Trustee’s certificate
of authentication to be borne by such Securities shall be substantially of the tenor and purport as set forth in one or more indentures
supplemental hereto or as provided in a Board Resolution, and set forth in an Officer’s Certificate, and they may have such letters,
numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as
the Company may deem appropriate and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with
any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which Securities
of that series may be listed, or to conform to usage.


Section
2.3 Denominations; Provisions for Payment.


The Securities shall be issuable as registered Securities and in
the minimum denomination of two thousand U.S. dollars ($2,000) or any integral multiple of one thousand U.S. dollars ($1,000) in excess
thereof, subject to Section 2.1(11). The Securities of a particular series shall bear interest payable on the dates and at the rate specified
with respect to that series. The principal of and the interest on the Securities of any series, as well as any premium thereon, shall
be payable in the coin or currency of the U.S. that at the time is legal tender for public and private debt, at the office or agency of
the Company maintained for that purpose in the United States, which shall initially be an office or agency of the Trustee. Each Security
shall be dated the date of its authentication. Interest on the Securities shall be computed on the basis of a 360-day year composed of
twelve 30-day months. Presentment and surrender of the Securities is required for final payment thereon.


The interest installment on any Security that is payable, and is
punctually paid or duly provided for, on any Interest Payment Date for Securities of that series shall be paid to the Person in whose
name said Security (or one or more Predecessor Securities) is registered at the close of business on the regular record date for such
interest installment. In the event that any Security of a particular series or portion thereof is called for redemption and the redemption
date is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest
on such Security will be paid upon presentation and surrender of such Security as provided in Section 3.3.


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


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



    	9



     


    




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


Unless otherwise set forth in a Board Resolution or one or more
indentures supplemental hereto establishing the terms of any series of Securities pursuant to Section 2.1 hereof, the term “regular
record date” as used in this Section with respect to a series of Securities and any Interest Payment Date for such series shall
mean either the fifteenth day of the month immediately preceding the month in which an Interest Payment Date established for such series
pursuant to Section 2.1 hereof shall occur, if such Interest Payment Date is the first day of a month, or the last day of the month immediately
preceding the month in which an Interest Payment Date established for such series pursuant to Section 2.1 hereof shall occur, if such
Interest Payment Date is the fifteenth day of a month, whether or not such date is a Business Day.


Subject to the foregoing provisions of this Section and Sections
2.5 and 2.11, each Security of a series delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security
of such series shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security.


Section
2.4 Execution and Authentication.


The Securities shall be signed on behalf of the Company by an Authorized
Officer and, to the extent necessary, under its corporate seal. Signatures may be in the form of a manual or facsimile signature.


The Company may use the facsimile signature of any Person who shall
have been an Authorized Officer thereof, notwithstanding the fact that at the time the Securities shall be authenticated and delivered
or disposed of such Person shall have ceased to be such an officer of the Company. To the extent a Company seal is necessary, the Company
seal may be in the form of a facsimile of such seal and may be impressed, affixed, imprinted or otherwise reproduced on the Securities.
The Securities may contain such notations, legends or endorsements required by law, stock exchange rule or usage. Each Security shall
be dated the date of its authentication by the Trustee.



    	10



     


    




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


In authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall receive, and (subject to Section 7.1) shall be fully protected
in conclusively relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with the
provisions of this Indenture.


The Trustee shall not be required to authenticate such Securities
if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.


Section
2.5 Registration of Transfer and Exchange.


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


(b)              
Upon surrender for transfer of any Security at the office of the Security Registrar, the Company shall execute, the Trustee shall
authenticate and the Security Registrar shall deliver in the name of the transferee or transferees a new Security or Securities of the
same series as the Security presented for a like aggregate principal amount.


All Securities presented or surrendered for exchange or registration
of transfer, as provided in this Section, shall be accompanied (if so required by the Company or the Security Registrar) by a written
instrument or instruments of transfer, in form satisfactory to the Company or the Security Registrar, duly executed by the registered
holder or by such holder’s duly authorized attorney in writing.



    	11



     


    




(c)               
Except as provided pursuant to Section 2.1 pursuant to a Board Resolution, and set forth in an Officer’s Certificate, or
established in one or more indentures supplemental to this Indenture, no service charge shall be made for any exchange or registration
of transfer of Securities, or issue of new Securities in case of partial repurchase or redemption of any series, but the Company and the
Trustee may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than exchanges
pursuant to Section 2.6, Section 3.3(b) and Section 9.4 not involving any transfer.


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


(e)               
Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and
each such registration shall be noted on the register for the Securities.


(f)               
The Security Registrar shall provide to the Trustee such information as the Trustee may reasonably require in connection with the
delivery by such Security Registrar of Securities upon transfer or exchange of Securities.


(g)              
The provisions of this Section 2.5 are, with respect to any Global Security, subject to Section 2.11 hereof.


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


(i)                
Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.


Section
2.6 Temporary Securities.


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



    	12



     


    




Section
2.7 Mutilated, Destroyed, Lost or Stolen Securities.


In case any temporary or definitive Security shall become mutilated
or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon a Company Request, the
Trustee (subject as aforesaid) shall authenticate and deliver, a new Security of the same series, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed,
lost or stolen. In every case, the requirements of Section 8-405 of the Uniform Commercial Code shall be met and the applicant for a substituted
Security shall furnish to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction
of the destruction, loss or theft of the applicant’s Security and of the ownership thereof. The Trustee may authenticate any such
substituted Security and deliver the same upon the delivery of a Company Order. Upon the issuance of any substituted Security, the Company
may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected therewith.


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


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



    	13



     


    




Section
2.8 Cancellation.


All Securities surrendered for the purpose of payment, redemption,
exchange or registration of transfer shall, if surrendered to the Company or any Paying Agent, be delivered to the Trustee for cancellation,
or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly required
or permitted by any of the provisions of this Indenture. On the delivery of a Company Order at the time of such surrender, the Trustee
shall cancel Securities held by the Trustee in accordance with its standard procedures and applicable law and provide confirmation to
the Company of such cancellation if requested by the Company. In the absence of such request, the Trustee may dispose of canceled Securities
in accordance with its standard procedures and deliver evidence of cancellation to the Company. If the Company shall otherwise acquire
any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are delivered to the Trustee for cancellation.


Section
2.9 Benefits of Indenture.


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


Section
2.10 Authenticating Agent.


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


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

Section
2.11 Global Securities.


(a)               
If the Company shall establish pursuant to Section 2.1 that the Securities of a particular series are to be issued as a Global
Security, then the Company shall execute and the Trustee shall, in accordance with Section 2.4, authenticate and deliver, a Global Security
that (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, all of the Outstanding Securities
of such series, (ii) shall be registered in the name of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: “Except
as otherwise provided in Section 2.11 of this Indenture, this Security may be transferred, in whole but not in part, only to another nominee
of the Depositary or to a successor Depositary or to a nominee of such successor Depositary.”


(b)              
Notwithstanding the provisions of Section 2.5, the Global Security of a series may be transferred, in whole but not in part and
in the manner provided in Section 2.5, only to another nominee of the Depositary for such series, or to a successor Depositary for such
series selected or approved by the Company or to a nominee of such successor Depositary. Nothing in this Section 2.11(b) shall prohibit
or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this
Indenture.


(c)               
If at any time the Depositary for a series of the Securities notifies the Company that it is unwilling or unable to continue as
Depositary for such series or if at any time the Depositary for such series shall no longer be registered or in good standing under the
Exchange Act, or other applicable statute or regulation, and a successor Depositary for such series is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such condition, as the case may be, or if an Event of Default has occurred
and is continuing and the Company has received a request from the Depositary, this Section 2.11 shall no longer be applicable to the Securities
of such series and the Company will execute, and subject to Section 2.4, the Trustee will authenticate and deliver the Securities of such
series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security of such series in exchange for such Global Security. In addition, the Company may at any time determine
that the Securities of any series shall no longer be represented by a Global Security and that the provisions of this Section 2.11 shall
no longer apply to the Securities of such series. In such event the Company will execute and, subject to Section 2.4, the Trustee, upon
receipt of an Officer’s Certificate evidencing such determination by the Company, will authenticate and deliver the Securities of
such series in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to
the principal amount of the Global Security of such series in exchange for such Global Security. Upon the exchange of the Global Security
for such Securities in definitive registered form without coupons, in authorized denominations, the Global Security shall be canceled
by the Trustee. Such Securities in definitive registered form issued in exchange for the Global Security pursuant to this Section 2.11(c)
shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names
such Securities are so registered.



    	15



     


    




Section
2.12 CUSIP and ISIN Numbers.


The Company, in issuing the Securities, shall use CUSIP and ISIN
numbers for such Securities (if then generally in use). The Trustee shall use CUSIP and ISIN numbers in notices of redemption as a convenience
to holders; provided, however, that neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP or ISIN
number that appears on any Security, check, advice of payment or redemption notice, and 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 redemption and that
reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing in the event of any change in the
CUSIP or ISIN numbers.


ARTICLE
III

REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS


Section
3.1 Redemption.


The Company may redeem the Securities of any series issued hereunder
on and after the dates and in accordance with the terms established for such series pursuant to Section 2.1 hereof. The provisions of
this Article III may be modified, amended or replaced, in part or in their entirety, with Securities of any series, by an Officer’s
Certificate pursuant to a Board Resolution or one or more indentures supplemental hereto, in each case in accordance with Section 2.1
hereof.


Section
3.2 Notice of Redemption.


(a)               
In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Securities of any
series in accordance with any right the Company reserved for itself to do so pursuant to Section 2.1 hereof, the Company shall, or shall
cause the Trustee to, give notice of such redemption to holders of the Securities of such series to be redeemed by mailing, first class
postage prepaid (or, in the case of Securities held in book-entry form, by electronic transmission), a notice of such redemption not less
than 30 days and not more than 60 days (except in accordance with Articles XI and XII) before the date fixed for redemption of that series
to such holders at their last addresses as they shall appear upon the Security Register, unless a shorter period is specified in the Securities
to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether
or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of any Security of any series
designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption
of any other Securities of such series or any other series. In the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officer’s Certificate evidencing compliance with any such restriction.



    	16



     


    




Each such notice of redemption shall specify the date fixed for
redemption and the redemption price at which Securities of that series are to be redeemed, and shall state that payment of the redemption
price of such Securities to be redeemed will be made at the office or agency of the Paying Agent or as otherwise established in a Board
Resolution or an indenture supplemental hereto, upon presentation and surrender of such Securities, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, that from and after said date interest will cease to accrue and that the
redemption is from a sinking fund, if such is the case. If less than all the Securities of a series are to be redeemed, the notice to
the holders of Securities of that series to be redeemed in part shall specify the particular Securities to be so redeemed.


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


(b)              
If less than all the Securities of a series are to be redeemed, the Company shall give the Trustee at least 45 days’ notice
(unless a shorter notice shall be satisfactory to the Trustee) in advance of the date fixed for redemption as to the aggregate principal
amount of Securities of the series to be redeemed, and thereupon the Trustee shall select, (i) if the Securities are in the form of Global
Securities, in accordance with the procedures of the Depositary, or (ii) if the Securities are not in the form of Global Securities, by
lot, a portion or portions (equal to one thousand U.S. dollars ($1,000) or any integral multiple thereof) of the principal amount of such
Securities of a denomination larger than $2,000, the Securities to be redeemed and shall thereafter promptly notify the Company in writing
of the numbers of the Securities to be redeemed, in whole or in part. The Company may, if and whenever it shall so elect, by delivery
of instructions signed on its behalf by an Authorized Officer, instruct the Trustee or any Paying Agent to call all or any part of the
Securities of a particular series for redemption and to give notice of redemption in the manner set forth in this Section, such notice
to be in the name of the Company or its own name as the Trustee or such Paying Agent may deem advisable. In any case in which notice of
redemption is to be given by the Trustee or any such Paying Agent, the Company shall deliver or cause to be delivered to, or permit to
remain with, the Trustee or such Paying Agent, as the case may be, such Security Register, transfer books or other records, or suitable
copies or extracts therefrom, sufficient to enable the Trustee or such Paying Agent to give any notice by mail that may be required under
the provisions of this Section.


Section
3.3 Payment Upon Redemption.


(a)               
If the giving of notice of redemption shall have been completed as above provided, the Securities or portions of Securities of
the series to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at
the applicable redemption price, together with interest accrued to the date fixed for redemption and interest on such Securities or portions
of Securities shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such
redemption price and accrued interest with respect to any such Security or portion thereof. On presentation and surrender of such Securities
on or after the date fixed for redemption at the place of payment specified in the notice, said Securities shall be paid and redeemed
at the applicable redemption price for such series, together with interest accrued thereon to the date fixed for redemption (but if the
date fixed for redemption is an interest payment date, the interest installment payable on such date shall be payable to the registered
holder at the close of business on the applicable record date pursuant to Section 2.3).



    	17



     


    




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


Section
3.4 Sinking Fund.


If Securities of a series provide for a sinking fund as contemplated
by Section 2.1, the provisions of this Section 3.4 and Sections 3.5 and 3.6 shall be applicable to any sinking fund for the retirement
of Securities of a series, except as otherwise specified as contemplated by Section 2.1 for Securities of such series.


The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess
of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund
payment.” If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject
to reduction as provided in Section 3.5. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided
for by the terms of Securities of such series.


Section
3.5 Satisfaction of Sinking Fund Payments With Securities.


The Company (i) may deliver Outstanding Securities of a series and
(ii) may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms
of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in
each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be
made pursuant to the terms of such Securities as provided for by the terms of such series, provided that such Securities have not been
previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the redemption price specified

Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of the series, the portion
thereof, if any, that is to be satisfied by delivering and crediting Securities of that series pursuant to Section 3.5 and the basis for
such credit and will, together with such Officer’s Certificate, deliver to the Trustee any Securities to be so delivered. Not less
than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund

Section
4.2 Paying Agent and Security Registrar.


(a)               
So long as any series of the Securities remain Outstanding, the Company shall maintain an office or agency where Securities may
be presented for registration of transfer or for exchange (“Security Registrar”), an office or agency where Securities
may be presented for payment (“Paying Agent”) and an office or agency where notices to or upon the Company in respect
of the Securities and this Indenture may be served. The Security Registrar shall keep a register for the recordation of, and shall record,
the names and addresses of holders of the Securities, the Securities held by each holder and the transfer and exchange of Securities (the
 “Security Register”). The entries in the Security Register shall be conclusive, and the parties may treat each Person
whose name is recorded in the Security Register pursuant to the terms hereof as a holder hereunder for all purposes of this Indenture.
The Company may have one or more co-Security Registrars and one or more additional Paying Agents.


The Company hereby initially designates the Trustee as Paying Agent
and Security Registrar, and the Corporate Trust Office shall be considered as one such office or agency of the Company for each of the
aforesaid purposes, such designation to continue with respect to such office or agency until the Company shall, by written notice signed
by an Authorized Officer and delivered to the Trustee, designate some other office or agency for such purposes or any of them.

(b)              
The Company shall enter into an appropriate agency agreement with any Security Registrar, Paying Agent, or co-registrar not a party
to this Indenture, which shall incorporate the terms of the Trust Indenture Act. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of any such agent. If the
Company fails to maintain a Security Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation
therefor. The Company and any of its Subsidiaries may act as Paying Agent, Security Registrar or co-registrar.


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


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


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


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


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


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


(e)               
Notwithstanding anything in this Section to the contrary, the Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or direct any Paying Agent to pay, to the Trustee all sums held in trust
by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which such sums
were held by the Company or such Paying Agent; and, upon such payment by the Company or any Paying Agent to the Trustee, the Company or
such Paying Agent shall be released from all further liability with respect to such money.

pursuant to Section 13 or Section 15(d) of the Exchange Act; provided, however, the Company shall not be required to deliver to the Trustee
any materials for which the Company has sought and received confidential treatment by the Commission; and provided further, so long as
such filings by the Company are available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (EDGAR),

(b)              
Delivery of such reports, information and documents to the Trustee shall be for informational purposes only and the Trustee’s
receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of the covenants contained in this Indenture (as to which the Trustee is entitled
to conclusively rely upon an Officer’s Certificate).


Section
5.4 Reports by the Trustee.

REMEDIES OF THE TRUSTEE AND

SECURITYHOLDERS ON EVENT OF DEFAULT


Section
6.1 Events of Default.


(a)               
Whenever used herein with respect to Securities of a particular series, unless otherwise specified in a Board Resolution or in
an indenture supplemental hereto, “Event of Default” means any one or more of the following events that has occurred
and is continuing:


(1)              
the Company defaults in the payment of any installment of interest upon any of the Securities of that series, as and when the same
shall become due and payable, and such default continues for a period of 30 days; provided, however, that a valid extension of an interest
payment period by the Company in accordance with the terms of any Board Resolution or indenture supplemental hereto shall not constitute
a default in the payment of interest for this purpose;


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


(3)              
the Company defaults in the performance or breach of its covenants or agreements with respect to that series contained in this
Indenture or otherwise established with respect to that series of Securities pursuant to Section 2.1 hereof (other than a covenant or
agreement that has been expressly included in this Indenture solely for the benefit of one or more series of Securities other than such
series) for a period of 90 consecutive days after the date on which written notice of such failure, requiring the same to be remedied
and stating that such notice is a “Notice of Default” hereunder, shall have been given to the Company by the Trustee,
by registered or certified mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Securities
of that series at the time Outstanding;


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


(5)              
a court of competent jurisdiction enters an order under any Bankruptcy Law that (i) is for relief against the Company in an involuntary
case, (ii) appoints a Custodian of the Company for all or substantially all of its property or (iii) orders the liquidation of the Company,
and the order or decree remains unstayed and in effect for 60 consecutive days; or



    	23



     


    




(6)              
certain other specified events, as may be provided for in a Board Resolution or in a supplemental indenture.


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


(c)               
At any time after the principal of (and premium, if any, on) and accrued and unpaid interest on the Securities of that series shall
have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the holders of a majority in aggregate principal amount of the Securities of that series then Outstanding
hereunder, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (i) the Company
has paid or deposited with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of that series
and the principal of (and premium, if any, on) any and all Securities of that series that shall have become due otherwise than by acceleration
(with interest upon such principal and premium, if any, and, to the extent that such payment is enforceable under applicable law, upon
overdue installments of interest, at the rate per annum expressed in the Securities of that series to the date of such payment or deposit)
and the amount payable to the Trustee under Section 7.6, and (ii) any and all Events of Default under this Indenture with respect to such
series, other than the nonpayment of principal of (and premium, if any, on) and accrued and unpaid interest on Securities of that series
that shall not have become due by their terms, shall have been remedied or waived as provided in Section 6.6.


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


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

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


(a)               
The Company covenants that (i) in case it shall default in the payment of any installment of interest on any of the Securities
of a series, and such default shall have continued for a period of 30 days, or (ii) in case it shall default in the payment of the principal
of (or premium, if any, on) any of the Securities of a series when the same shall have become due and payable, whether upon maturity of
the Securities of a series or upon redemption or upon declaration or otherwise, or in any payment required by any sinking or analogous
fund established with respect to that series as and when the same shall have become due and payable, then, upon demand of the Trustee,
the Company will pay to the Trustee, for the benefit of the holders of the Securities of that series, the whole amount that then shall
have been become due and payable on all such Securities for principal (and premium, if any) or interest, or both, as the case may be,
with interest upon the overdue principal (and premium, if any) and (to the extent that payment of such interest is enforceable under applicable
law) upon overdue installments of interest at the rate per annum expressed in the Securities of that series; and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee under
Section 7.6.


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


(c)               
In case of any receivership, insolvency, liquidation, bankruptcy, reorganization, readjustment, arrangement, composition or judicial
proceedings affecting the Company, or its creditors or property, the Trustee shall have power to intervene in such proceedings and take
any action therein that may be permitted by the court and shall (except as may be otherwise provided by law) be entitled to file such
proofs of claim and other papers and documents as may be necessary or advisable in order to have the claims of the Trustee and of the
holders of Securities of such series allowed for the entire amount due and payable by the Company under this Indenture at the date of
institution of such proceedings and for any additional amount that may become due and payable by the Company after such date, and to collect
and receive any moneys or other property payable or deliverable on any such claim, and to distribute the same after the deduction of the
amount payable to the Trustee under Section 7.6; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized
by each of the holders of Securities of such series to make such payments to the Trustee, and, in the event that the Trustee shall consent
to the making of such payments directly to such Securityholders, to pay to the Trustee any amount due it under Section 7.6.


(d)              
All rights of action and of asserting claims under this Indenture, or under any of the terms established with respect to Securities
of that series, may be enforced by the Trustee without the possession of any of such Securities, or the production thereof at any trial
or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee
of an express trust, and any recovery of judgment shall, after provision for payment to the Trustee of any amounts due under Section 7.6,
be for the ratable benefit of the holders of the Securities of such series.



    	25



     


    




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


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


Section
6.3 Application of Moneys Collected.


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


FIRST: To the payment of reasonable costs and
expenses of collection and of all amounts payable to the Trustee under Section 7.6;


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


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


The Trustee may fix a record date and payment date for any payment
to holders pursuant to this Section 6.3. At least 15 days before such record date, the Company shall mail to each holder and the Trustee
a notice that states the record date, the payment date and the amount to be paid.

Section
6.4 Limitation on Suits.


No holder of any Security of any series shall have any right by
virtue or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under
or with respect to this Indenture or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (i) such
holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof with respect to
the Securities of such series specifying such Event of Default, as hereinbefore provided; (ii) the holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder; (iii) such holder or holders shall have offered to the Trustee such indemnity
reasonably satisfactory to it against the costs, losses, expenses and liabilities to be incurred therein or thereby; (iv) the Trustee
for 60 days after its receipt of such notice, request and offer of indemnity, shall have failed to institute any such action, suit or
proceeding and (v) during such 60 day period, the holders of a majority in principal amount of the Securities of that series do not give
the Trustee a direction inconsistent with the request.


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


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


(a)               
Except as otherwise provided in Section 2.7, all powers and remedies given by this Article VI to the Trustee or to the Securityholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee
or the holders of the Securities, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture or otherwise established with respect to such Securities.


(b)              
No delay or omission of the Trustee or of any holder of any of the Securities to exercise any right or power accruing upon any
Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any
such default or an acquiescence therein; and, subject to the provisions of Section 6.4, every power and remedy given by this Article VI
or by law to the Trustee or the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.

Section
6.6 Control by Securityholders.


The holders of a majority in aggregate principal amount of the Securities
of any series at the time Outstanding, determined in accordance with Section 8.4, shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee
with respect to such series; provided, however, that such direction shall not be in conflict with any rule of law or with this Indenture.
Subject to the provisions of Section 7.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good
faith shall, by a Trust Officer or officers of the Trustee, determine that the proceeding so directed, subject to the Trustee’s
duties under the Trust Indenture Act, would involve the Trustee in personal liability or might be unduly prejudicial to the Securityholders
not involved in the proceeding. The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding
affected thereby, determined in accordance with Section 8.4, may on behalf of the holders of all of the Securities of such series waive
any past default in the performance of any of the covenants contained herein or established pursuant to Section 2.1 with respect to such
series and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on, any of the Securities
of that series as and when the same shall become due by the terms of such Securities otherwise than by acceleration (unless such default
has been cured and a sum sufficient to pay all matured installments of interest and principal and any premium has been deposited with
the Trustee (in accordance with Section 6.1(c)), which requires the consent of each holder affected by such waiver. Upon any such waiver,
the default covered thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee and the holders
of the Securities of such series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall
extend to any subsequent or other default or impair any right consequent thereon.


Section
6.7 Undertaking to Pay Costs.


All parties to this Indenture agree, and each holder of any Securities
by such holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it
as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not
apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder, or group of Securityholders, holding more than
10% in aggregate principal amount of the Outstanding Securities of any series, or to any suit instituted by any Securityholder for the
enforcement of the payment of the principal of (or premium, if any) or interest on any Security of such series, on or after the respective
due dates expressed in such Security or established pursuant to this Indenture.

ARTICLE
VII

CONCERNING THE TRUSTEE


Section
7.1 Certain Duties and Responsibilities of Trustee.


(a)               
The Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a series and after the curing of
all Events of Default with respect to the Securities of that series that may have occurred, shall undertake to perform with respect to
the Securities of such series such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants
shall be read into this Indenture against the Trustee. In case an Event of Default with respect to the Securities of a series has occurred
(that has not been cured or waived), the Trustee shall exercise with respect to Securities of that series such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use
under the circumstances in the conduct of his or her own affairs. Except during the continuance of an Event of Default with respect to
the Securities of a series, in the absence of bad faith on its part, the Trustee may with respect to the Securities of such series conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon 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 of mathematical calculations
or other facts stated therein).


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


(i)                
this subsection (b) shall not be construed to limit the effect of subsection (a) of this Section;


(ii)              
the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer or Trust Officers of the Trustee,
unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;


(iii)            
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
the direction of the holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding relating
to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee under this Indenture with respect to the Securities of that series; and


(iv)            
None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur
personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable
ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or
adequate indemnity against such risk is not reasonably assured to it.



    	29



     


    




(c)               
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.


Section
7.2 Certain Rights of Trustee.


Except as otherwise provided in Section 7.1:


(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, consent, order, approval, bond, security or other paper or document believed
by it to be genuine and to have been signed or presented by the proper party or parties;


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


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


(d)              
The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request,
order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have
offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, losses, expenses and liabilities that may
be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of
an Event of Default with respect to a series of the Securities (that has not been cured or waived), to exercise with respect to Securities
of that series such of the rights and powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise,
as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs;


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


(f)               
The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, security, or other papers or documents, unless requested
in writing so to do by the holders of not less than a majority in principal amount of the Outstanding Securities of the particular series
affected thereby (determined as provided in Section 8.4),



    	30



     


    




and, if so requested, except as otherwise prohibited by applicable
law or as would reasonably be expected to violate or result in the loss or impairment of any attorney-client or work product privilege,
the Trustee shall be entitled to examine the books, records, and premises of the Company, personally or by agent, or attorney, and it
shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; provided, however, that the Company
shall not be required to provide access or furnish information in the event of any litigation involving this Indenture or the Securities
except pursuant to applicable rules of discovery; and provided, further, that if the payment within a reasonable time to the Trustee of
the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee,
not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable
indemnity against such costs, expenses or liabilities as a condition to so proceeding. The reasonable expense of every such examination
shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand;


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


(h)              
In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such
loss or damage and regardless of the form of action;


(i)                
The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof
or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Securities and this Indenture;


(j)                
The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to
be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian
and other Person employed to act hereunder;


(k)              
The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder;


(l)                
The Trustee shall not be liable for the acts or omissions of any other agent of the Company, and may assume performance by any
such agent of its duties, absent written notice or actual knowledge to the contrary; and


(m)            
The permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an obligation or
duty to do so.


Section
7.3 Trustee Not Responsible for Recitals or Issuance or Securities.


(a)               
The recitals contained herein and in the Securities shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.



    	31



     


    




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


(c)               
The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds of such
Securities, or for the use or application of any moneys paid over by the Trustee in accordance with any provision of this Indenture or
established pursuant to Section 2.1, or for the use or application of any moneys received by any Paying Agent other than the Trustee.


Section
7.4 May Hold Securities and Otherwise Deal With the Company.


Subject to the Trust Indenture Act, the Trustee, the Security Registrar,
any Paying Agent or any other agent of the Company, in its individual or any other capacity, may buy, own, hold, sell and become the pledgee
of any of the Securities or any other evidences of indebtedness or other securities, whether heretofore or hereafter created or issued,
of the Company or any Subsidiary or Affiliate of the Company with the same rights it would have if it were not Trustee, Security Registrar,
Paying Agent or such other agent; and the Trustee may engage or be interested in any financial or other transaction with the Company or
any Subsidiary or Affiliate of the Company, including, without limitation, secured and unsecured loans to the Company or any Subsidiary
or Affiliate of the Company; and may maintain any and all other general banking and business relations with the Company and any Subsidiary
or Affiliate of the Company with like effect and in the same manner and to the same extent as if the Trustee were not a party to this
Indenture; and no implied covenant shall be read into this Indenture against the Trustee in respect of any such matters.


Section
7.5 Moneys Held in Trust.


Subject to the provisions of Sections 11.2, 12.5, 12.6 and 12.7,
all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were
received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for
interest on any moneys received by it hereunder except such as it may agree with the Company to pay thereon.


Section
7.6 Compensation and Reimbursement.


(a)               
The Company covenants and agrees to pay to the Trustee, and the Trustee shall be entitled to, such compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee of an express trust) as the Company and the Trustee may
from time to time agree in writing, for all services rendered by it in the execution of the trusts hereby created and in the exercise
and performance of any of the powers and duties hereunder of the Trustee, and, except as otherwise expressly provided herein, the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of
its counsel and of all Persons not regularly in its employ), except any such expense, disbursement or advance as may arise from its negligence
or willful misconduct and except as the Company and Trustee may from time to time agree in writing. The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold it harmless against, any loss, costs, damages, liability
or expense incurred without negligence or willful misconduct on the part of the Trustee (as determined by a court of competent jurisdiction
in a final and non-appealable judgment) and arising out of or in connection with the acceptance or administration of this trust, including
the reasonable costs and expenses of defending itself against any claim of liability in the premises.



    	32



     


    




(b)              
To secure the Company’s payment obligations in this Section 7.6, the Trustee shall have a lien prior to the Securities of
any series on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on particular
Securities of such series.


When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.1(a)(4) or 6.1(a)(5) occurs, the expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law.


The provisions of this Section 7.6 shall survive the resignation
or removal of the Trustee and the termination or satisfaction of this Indenture.


Section
7.7 Reliance on Officer’s Certificate.


Except as otherwise provided in Section 7.1, whenever in the administration
of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved or established
prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively
proved and established by an Officer’s Certificate delivered to the Trustee and such certificate, in the absence of negligence or
willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken
by it under the provisions of this Indenture upon the faith thereof.


Section
7.8 Disqualification; Conflicting Interests.


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


Section
7.9 Corporate Trustee Required; Eligibility.


There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing business under the laws of the U.S. or any state or territory
thereof or of the District of Columbia, or a corporation or other Person permitted to act as trustee by the Commission, authorized under
such laws to exercise corporate trust powers, having (or, in the case of a subsidiary of a bank holding company, its bank holding company
parent shall have) a combined capital and surplus of at least one hundred million U.S. dollars ($100,000,000), and subject to supervision
or examination by federal, state, territorial, or District of Columbia authority.



    	33



     


    




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


Section
7.10 Resignation and Removal; Appointment of Successor.


(a)               
The Trustee or any successor hereafter appointed may at any time resign with respect to the Securities of one or more series by
giving written notice thereof to the Company and by transmitting notice of resignation by mail, first class postage prepaid (or, in the
case of Securities held in book-entry form, by electronic transmission), to the Securityholders of such series, as their names and addresses
appear upon the Security Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with
respect to Securities of such series by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been
so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning Trustee may at
the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor trustee with respect to Securities
of such series, or the holders of at least 10% in the aggregate principal amount of Outstanding Securities may petition any such court
for the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint
a successor trustee.


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


(i)                
the Trustee shall fail to comply with the provisions of Section 7.8 after written request therefor by the Company or by any Securityholder
who has been a bona fide holder of a Security or Securities for at least six months; or


(ii)              
the Trustee shall cease to be eligible in accordance with the provisions of Section 7.9 and shall fail to resign after written
request therefor by the Company or by any such Securityholder; or


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



    	34



     


    




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


(c)               
The holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding may, upon 30 days’
notice, remove the Trustee with respect to such series by so notifying the Trustee and the Company and may appoint a successor Trustee
for such series with the consent of the Company.


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


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


Section
7.11 Acceptance of Appointment by Successor.


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


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



    	35



     


    




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


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


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


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


Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall
be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration
of the trust created by this Indenture), shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified
under the provisions of Section 7.8 and eligible under the provisions of Section 7.9, without the execution or filing of any paper or
any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case any Securities shall
have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor
Trustee had itself authenticated such Securities.



    	36



     


    




Section
7.13 Preferential Collection of Claims Against the Company.


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


Section
7.14 Notice of Default.


If any Default or any Event of Default occurs and is continuing
and if the Trustee has notice of such Default or Event of Default, the Trustee shall mail to each Securityholder in the manner and to
the extent provided in Section 313(c) of the Trust Indenture Act notice of the Default or Event of Default within 90 days after it occurs
(or, the Trustee does not have notice of such Default or Event of Default until after that time, 15 days after the Trustee has notice
of such Default or Event of Default), unless such Default or Event of Default has been cured; provided, however, that, except in the case
of a default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in withholding
such notice if and so long as the Trustee in good faith determines that the withholding of such notice is in the interest of the Securityholders.


Section
7.15 Limitation of Liability


The Trustee is entering into this Indenture and the other documents
contemplated hereby and related hereto to which it is a party solely in its capacity as trustee under the Indenture and not in its individual
capacity (except as expressly stated herein) and in no case shall the Trustee (or any Person acting as successor trustee under this Indenture)
be personally liable for or on account of any of the statements, representations, warranties, covenants or obligations stated to be those
of the Company hereunder or thereunder, all such liability, if any, being expressly waived by the parties hereto and any person claiming
by, through or under such party.


ARTICLE
VIII

CONCERNING THE SECURITYHOLDERS


Section
8.1 Evidence of Action by Securityholders.


Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of the Securities of a particular series may take any action (including
the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at
the time of taking any such action the holders of such majority or specified percentage of that series have joined therein may be evidenced
by any instrument or any number of instruments of similar tenor executed by such holders of Securities of that series in person or by
agent or proxy appointed in writing.


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



    	37



     


    




Section
8.2 Proof of Execution by Securityholders.


Subject to the provisions of Section 7.1, proof of the execution
of any instrument by a Securityholder (such proof will not require notarization) or his agent or proxy and proof of the holding by any
Person of any of the Securities shall be sufficient if made in the following manner:


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


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


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


Section
8.3 Who May Be Deemed Owners.


Prior to the due presentment for registration of transfer of any
Security, the Company, the Trustee, any Paying Agent and any Security Registrar may deem and treat the Person in whose name such Security
shall be registered upon the books of the Security Registrar as the absolute owner of such Security (whether or not such Security shall
be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security Registrar) for the purpose
of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.3) interest on such Security and
for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any
notice to the contrary.


Section
8.4 Certain Securities Owned by Company Disregarded.


In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction, consent or waiver under this Indenture, the Securities of
that series that are owned by the Company or any other obligor on the Securities of that series or by any Person directly or indirectly
controlling or controlled by or under common control with the Company or any other obligor on the Securities of that series shall be disregarded
and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only Securities of such series that the Trustee actually knows
are so owned shall be so disregarded. The Securities so owned that have been pledged in good faith may be regarded as Outstanding for
the purposes of this Section, if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right so to act with
respect to such Securities and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee.

Section
8.5 Actions Binding on Future Securityholders.


At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 8.1, of the taking of any action by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection with such action, any holder of a Security of that series
that is shown by the evidence to be included in the Securities the holders of which have consented to such action may, by filing written
notice with the Trustee, and upon proof of holding as provided in Section 8.2, revoke such action so far as concerns such Security. Except
as aforesaid any such action taken by the holder of any Security shall be conclusive and binding upon such holder and upon all future
holders and owners of such Security, and of any Security issued in exchange therefor, on registration of transfer thereof or in place
thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the holders of
the majority or percentage in aggregate principal amount of the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the Securities of that series.

applicable (with such intention being evidenced by an Officer’s Certificate).


The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, and to make any further appropriate agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into any such supplemental indenture that affects the Trustee’s own rights, duties

on or after the redemption date) of such Securities.



    	41



     


    




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


Section
9.3 Effect of Supplemental Indentures.

indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.


Section

Securities of any series affected by a supplemental indenture, authenticated
and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article IX or of Section 10.1, may

any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities
of that series then Outstanding.


Section
9.5 Execution of Supplemental Indentures.


Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders
required to consent thereto as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless
such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee shall receive, in
addition to the documents required by Section 14.7(a), an Officer’s Certificate and an Opinion of Counsel stating that and as conclusive
evidence that any supplemental indenture executed pursuant to this Article IX is authorized or permitted by, and conforms to, the terms
of this Article IX, constitutes the legal, valid and binding obligation of the Company, enforceable against it in accordance with its
terms (subject to customary exceptions) and that it is proper for the Trustee under the provisions of this Article IX to join in the execution
thereof.


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

SATISFACTION AND DISCHARGE


Section
11.1 Satisfaction and Discharge of Indenture.


This Indenture shall upon Company Request cease to be of further
effect with respect to any series of Securities (except as to any surviving rights of registration of transfer or exchange of Securities
of such series herein expressly provided for or in the form of Security for such series and any right to receive additional amounts),
and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture
as to such series, when


(a)               
either


(i)                
all Securities of such series theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost
or stolen and which have been replaced or paid as provided in Section 2.7 and (ii) Securities for whose payment cash, Governmental Obligations
or a combination thereof 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 Sections 12.5 and 12.6) have been delivered to the Trustee for cancellation;
or


(ii)              
all such Securities of such series not theretofore delivered to the Trustee for cancellation, or


(A)            
have become due and payable by reason of the mailing of a notice of redemption or otherwise, or


(B)             
will become due and payable within one year,



    	44



     


    




and the Company, in the case of (A) or (B) above, has deposited
or caused to be deposited with the Trustee as trust funds in trust specifically pledged as security for, and dedicated solely to, the
benefit of the Securityholders of the Securities of that series, cash in U.S. dollars, Governmental Obligations or a combination thereof
in such amount as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness
on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest, if any,
to the date of such deposit (in the case of Securities which have become due and payable), or to the Stated Maturity or the Redemption
Date, as the case may be;


(b)              
in respect of clause (a)(ii), no Event of Default has occurred and is continuing on the date of deposit (other than an Event of
Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other indebtedness and,
in each case, the granting of certain liens to secure such borrowing);


(c)               
the Company or any guarantor has paid or caused to be paid all other sums payable hereunder by the Company with respect to such
series; and


(d)              
the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money towards the
payment of the notes at maturity or on the redemption date, as the case may be.


Notwithstanding the satisfaction and discharge of this Indenture
with respect to such series, the obligations of the Company to the Trustee with respect to such series under this Section 11.1 and Sections
7.6 and 7.10, the obligations of the Company to any Authenticating Agent under Section 2.10, and, if cash, Governmental Obligations or
a combination thereof shall have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section, the obligations
of the Trustee under Section 11.2, shall survive.


Section
11.2 Application of Trust Money.


Subject to the provisions of Section 12.6, all cash and Governmental
Obligations deposited with the Trustee pursuant to Section 11.1 shall be held in trust and applied by the Trustee, in accordance with
the provisions of the series of Securities and this Indenture, to the payment, either directly or through any Paying Agent (including
the Company or any of its Subsidiaries acting as Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of all sums
due and to become due thereon in respect of the principal of (and premium, if any) and interest, if any, on the Securities for which payment
of such cash and Governmental Obligations has been deposited with the Trustee.


If the Trustee or Paying Agent is unable to apply any cash or Governmental
Obligations in accordance with this Article XI by reason of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Company under this
Indenture and the Securities of such series shall be revived and reinstated as though no deposit had occurred pursuant to this Article
XI until such time as the Trustee or Paying Agent is permitted to apply all such cash and Governmental Obligations in accordance with
this Article XI; provided, however, that, if the Company has made any payment of principal, premium, if any, interest on or principal
of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of such
Securities to receive such payment from the cash and Governmental Obligations held by the Trustee or Paying Agent.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE


Section
12.1 Option to Effect Legal Defeasance or Covenant Defeasance.


The Company may at any time, at the option of its Board of Directors
evidenced by a Board Resolution set forth in an Officer’s Certificate, elect to have either Section 12.2 or 12.3 hereof be applied
to all outstanding Securities of a series upon compliance with the conditions set forth below in this Article XII.


Section
12.2 Legal Defeasance and Discharge.


Upon the Company’s exercise under Section 12.1 hereof of the
option applicable to this Section 12.2 with respect to a series of Securities, the Company will, subject to the satisfaction of the conditions
set forth in Section 12.4 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Securities of
such series on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose,
Legal Defeasance means that the Company will be deemed to have paid and discharged the entire Indebtedness represented by the Outstanding
Securities of such series, which will thereafter be deemed to be Outstanding only for the purposes of Section 12.5 hereof and the Articles
and other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under
such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:


(1)              
the rights of holders of Outstanding Securities of such series to receive payments in respect of the principal of, premium on,
if any, or interest on such Securities when such payments are due from the trust referred to in Section 12.4 hereof;


(2)              
the Issuers’ obligations with respect to such Securities under Article 2 and Section 4.2 hereof;


(3)              
the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith;
and


(4)              
this Article XII.


Subject to compliance with this Article XII, the Company may exercise
its option under this Section 12.2 with respect to a series of Securities, notwithstanding the prior exercise of its option under Section
12.3 hereof with respect to such series of Securities.


Section
12.3 Covenant Defeasance.



    	46



     


    




Upon the Company’s exercise under Section 12.1 hereof of the
option applicable to this Section 12.3 with respect to a series of Securities, the Company will, subject to the satisfaction of the conditions
set forth in Section 12.4 hereof, be released from its obligations under Section 5.3 and Article X and any additional covenants specified
in any Board Resolution or indenture supplemental hereto with respect to the Outstanding Securities of such series on and after the date
the conditions set forth in Section 12.4 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Securities
of such series will thereafter be deemed not Outstanding for the purposes of any direction, waiver, consent or declaration or act of holders
(and the consequences of any thereof) in connection with such covenants, but will continue to be deemed Outstanding for all other purposes
hereunder (it being understood that such Securities will not be deemed Outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the Outstanding Securities of such series, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in Section 5.3 or Article X and any additional covenants specified
in any Board Resolution or indenture supplemental hereto, whether directly or indirectly, by reason of any reference elsewhere herein
to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1 hereof with respect to Outstanding
Securities of such series, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.


Section
12.4 Conditions to Legal or Covenant Defeasance.


In order to exercise either Legal Defeasance or Covenant Defeasance
under either Section 12.2 or 12.3 hereof with respect to the Outstanding Securities of a particular series:


(1)              
the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Securityholders of the Securities of that
series, cash in U.S. dollars, Governmental Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion
of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, premium
on, if any, and interest on, the Outstanding Securities of such series on the stated date for payment thereof or on the applicable redemption
date, as the case may be, and the Company must specify whether the Securities of such series are being defeased to such stated date for
payment or to a particular redemption date;


(2)              
in the case of an election under Section 12.2 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that:


(A)            
the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or


(B)             
since the date of this Indenture, there has been a change in the applicable federal income tax law,


in either case to the effect that, and based thereon such Opinion
of Counsel shall confirm that, the holders of the Outstanding Securities of such series will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had not occurred;



    	47



     


    




(3)              
in the case of an election under Section 12.3 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that the holders of the Outstanding Securities of such series will not recognize income, gain or
loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal 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;


(4)              
no Default or Event of Default with respect to the Securities of such series shall have occurred and be continuing on the date
of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any
similar concurrent deposit relating to other Indebtedness), and the granting of liens to secure such borrowings);


(5)              
such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced)
to which the Company is a party or by which the Company is bound; and


(6)              
the Company must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.


Section
12.5 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.


Subject to Section 12.6 hereof, all cash and Governmental Obligations
(including the proceeds thereof) deposited with the Trustee pursuant to Section 12.4 hereof in respect of the Outstanding Securities of
a particular 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 Paying Agent) as the Trustee may determine,
to the holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required by law.


The Company will pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the cash or Governmental Obligations deposited pursuant to Section 12.4 hereof 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 the applicable series.


Notwithstanding anything in this Article XII to the contrary, the
Trustee shall deliver or pay to the Company from time to time upon Company Request any cash or Governmental Obligations held by it as
provided in Section 12.4 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 12.4(1) hereof), are in excess
of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section
12.6 Repayment to Company.


Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of, premium on, if any, or interest on any Security and remaining unclaimed
for two years after such principal, premium, if any, or interest, has become due and payable shall, unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property law, be paid to the Company on its request or (if then held by the
Company) will be discharged from such trust; and the holder of such Security will thereafter, as an unsecured general creditor, be permitted
to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before
being required to make any such repayment, may give written notice to the holder of such Security, at such holder’s address as it
appears upon the Security Register, that such money remains unclaimed and that, after a date specified therein, which will not be less
than 30 days from the date of such notification, any unclaimed balance of such money then remaining will, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Company.


Section
12.7 Reinstatement.


If the Trustee or Paying Agent is unable to apply any cash or Governmental
Obligations in accordance with Section 12.2 or 12.3 hereof, as the case may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture
and the Securities of the particular series shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.2
or 12.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such cash or Governmental Obligations in accordance
with Section 12.2 or 12.3 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium
on, if any, or interest on, any Security of the particular series following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the holders of such Securities to receive such payment from the cash or Governmental Obligations held by the
Trustee or Paying Agent.
