publication or general circulation of any newspaper or for any other reason, it is impossible or impracticable to make any publication

    	- 10 -



    	 



    

 


(ii)
that such Securities, when authenticated and delivered by the Trustee and issued by the Issuer in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Issuer enforceable against
the Issuer in accordance with their terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect relating to creditors’ rights
generally, and general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at
law).


 


The
Trustee shall have the right to decline to authenticate and deliver any Securities under this section if the Trustee, being advised
by counsel, determines that such action may not lawfully be taken by the Issuer or if the Trustee in good faith by its board of
directors or board of trustees, executive committee, or a trust committee of directors or trustees or Responsible Officers shall
determine that such action would expose the Trustee to personal liability.


 


If
the Issuer shall establish pursuant to Section 2.03 that the Securities of a series or a portion thereof are to be issued in the
form of one or more Registered Global Securities, then the Issuer shall execute (in accordance with Section 2.05) and the Trustee
shall authenticate and make available for delivery one or more Registered Global Securities that (i) shall represent and shall
be denominated in an amount equal to the aggregate Principal amount of all of the Securities of such series issued in such form
and not yet canceled, (ii) shall be registered in the name of the Depositary for such Registered Global Security or Securities
or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or its custodian or pursuant to
such Depositary’s instructions and (iv) shall bear a legend substantially to the following effect: “Unless and until
it is exchanged in whole or in part for Securities in definitive registered form, this Security may not be transferred except
as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee
of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.”


 


Section
2.05 Execution of Securities. The Securities shall be signed on behalf of the Issuer by the chairman of its Board of Directors,
its president, any vice president, its treasurer or any assistant treasurer, under its corporate seal and attested by its secretary
or any assistant secretary. Such signatures may be the manual or facsimile signatures of the present or any future such officers.
The seal of the Issuer may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced
on the Securities. Typographical and other minor errors or defects in any such reproduction of the seal or any such signature
shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee.


 


In
case any officer of the Issuer who shall have signed any of the Securities shall cease to be such officer before the Security
so signed shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security nevertheless may be
authenticated and delivered or disposed of as though the person who signed such Security had not ceased to be such officer of
the Issuer; and any Security may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of
such Security, shall be the proper officers of the Issuer, although at the date of the execution and delivery of this Indenture
any such person was not such an officer.

any Security executed by the Issuer 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.


 


Section
2.07 Denomination and Date of Securities; Payments of Interest. The Securities shall be issuable as registered securities
without coupons and in denominations as shall be specified as contemplated by Section 2.03. In the absence of any such specification
with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any
multiple thereof. The Securities shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with
such plan as the officers of the Issuer executing the same may determine as evidenced by the execution and authentication thereof.


 


Each
Security shall be dated the date of its authentication, shall bear interest, if any, from the date and shall be payable on the
dates, in each case, which shall be specified as contemplated by Section 2.03.


 


The
person in whose name any Security of any series is registered at the close of business on any record date applicable to a particular
series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on
such interest payment date notwithstanding any transfer or exchange of such Security subsequent to the record date and prior to
such interest payment date, except if and to the extent the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be paid to the persons in whose names Outstanding Securities
for such series are registered at the close of business on a subsequent record date (which shall be not less than five Business
Days prior to the date of payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer
to the Holders of Securities not less than 15 days preceding such subsequent record date. The term “record date”
as used with respect to any interest payment date (except a date for payment of defaulted interest) shall mean the date specified
as such in the terms of the Securities of any particular series, or, if no such date is so specified, if such interest payment
date is the first day of a calendar month, the fifteenth day of the next preceding calendar month or, if such interest payment
date is the fifteenth day of a calendar month, the first day of such calendar month, whether or not such record date is a Business
Day.


 


Section
2.08 Registration, Transfer and Exchange. The Issuer will keep or cause to be kept at each office or agency to be maintained
for the purpose as provided in Section 3.02 a register or registers in which, subject to such reasonable regulations as it may
prescribe, it will register, and will register the transfer of, Securities as in this Article provided. Such register shall be
in written form in the English language or in any other form capable of being converted into such form within a reasonable time.
At all reasonable times such register or registers shall be open for inspection by the Trustee.


 




    	- 12 -



    	 



    

 


At
the option of the Holder thereof, Registered Securities of any series (other than a Registered Global Security, except as set
forth below) may be exchanged for a Registered Security or Registered Securities of such series and tenor having authorized denominations
and an equal aggregate Principal amount, upon surrender of such Registered Securities to be exchanged at the agency of the Issuer
that shall be maintained for such purpose in accordance with Section 3.02 and upon payment, if the Issuer shall so require, of
the charges hereinafter provided. If the Securities of any series are issued in both registered and unregistered form, except
as otherwise established pursuant to Section 2.03, at the option of the Holder thereof, Unregistered Securities of any series
may be exchanged for Registered Securities of such series and tenor having authorized denominations and an equal aggregate Principal
amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Issuer that shall be maintained for
such purpose in accordance with Section 3.02 and upon payment, if the Issuer shall so require, of the charges hereinafter provided.
At the option of the Holder thereof, if Unregistered Securities of any series, maturity date, interest rate and Original Issue
Date are issued in more than one authorized denomination, except as otherwise established pursuant to Section 2.03, such Unregistered
Securities may be exchanged for Unregistered Securities of such series and tenor having authorized denominations and an equal
aggregate Principal amount, upon surrender of such Unregistered Securities to be exchanged at the agency of the Issuer that shall
be maintained for such purpose in accordance with Section 3.02 and upon payment, if the Issuer shall so require, of the charges
hereinafter provided. Registered Securities of any series may not be exchanged for Unregistered Securities of such series. Whenever
any Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and make available
for delivery, the Securities which the Holder making the exchange is entitled to receive.


 


All
Registered Securities presented for registration of transfer, exchange, redemption, conversion or payment shall be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly
executed by, the Holder or his attorney duly authorized in writing.


 


The
Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection
with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction.


 


Notwithstanding
any other provision of this Section 2.08, unless and until it is exchanged in whole or in part for Securities in definitive registered
form, a Registered Global Security representing all or a portion of the Securities of a series may not be transferred except as
a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a
nominee of such successor Depositary.


 


If
at any time the Depositary for any Registered Global Securities of any series notifies the Issuer that it is unwilling or unable
to continue as Depositary for such Registered Global Securities or if at any time the Depositary for such Registered Global Securities
shall no longer be eligible under applicable law, the Issuer shall appoint a successor Depositary eligible under applicable law
with respect to such Registered Global Securities. If a successor Depositary eligible under applicable law for such Registered
Global Securities is not appointed by the Issuer within 90 days after the Issuer receives such notice or becomes aware of such
ineligibility, the Issuer will execute, and the Trustee, upon receipt of the Issuer’s order for the authentication and delivery
of definitive Registered Securities of such series and tenor, will authenticate and make available for delivery Registered Securities
of such series and tenor, in any authorized denominations, in an aggregate Principal amount equal to the Principal amount of such
Registered Global Securities, in exchange for such Registered Global Securities.


 




    	- 13 -



    	 



    

 


The
Issuer may at any time and in its sole discretion determine that any Registered Global Securities of any series shall no longer
be maintained in global form. In such event, or in the event that there shall have occurred and be continuing an Event of Default
with respect to a series of Securities, the Issuer will, upon the request of any Holder, execute, and the Trustee, upon receipt
of the Issuer’s order for the authentication and delivery of definitive Registered Securities of such series and tenor,
will authenticate and make available for delivery, Registered Securities of such series and tenor in any authorized denominations,
in an aggregate Principal amount equal to the Principal amount of such Registered Global Securities, in exchange for such Registered
Global Securities.


 


Any
time the Registered Securities of any series are not in the form of Registered Global Securities pursuant to the preceding two
paragraphs, the Issuer agrees to supply the Trustee with a reasonable supply of certificated Registered Securities without the
legend required by Section 2.04 and the Trustee agrees to hold such Registered Securities in safekeeping until authenticated and
delivered pursuant to the terms of this Indenture.


 


If
established by the Issuer pursuant to Section 2.03 with respect to any Registered Global Security, the Depositary for such Registered
Global Security may surrender such Registered Global Security in exchange in whole or in part for Registered Securities of the
same series and tenor in definitive registered form on such terms as are acceptable to the Issuer and such Depositary. Thereupon,
the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, without service charge,


 


(i)
to the Person specified by such Depositary new Registered Securities of the same series and tenor, of any authorized denominations
as requested by such Person, in an aggregate Principal amount equal to and in exchange for such Person’s beneficial interest
in the Registered Global Security; and


 


(ii)
to such Depositary a new Registered Global Security in a denomination equal to the difference, if any, between the Principal amount
of the surrendered Registered Global Security and the aggregate Principal amount of Registered Securities authenticated and delivered
pursuant to clause (i) above.


 


Registered
Securities issued in exchange for a Registered Global Security pursuant to this Section 2.08 shall be registered in such names
and in such authorized denominations as the Depositary for such Registered Global Security, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee or an agent of the Issuer or the Trustee. The Trustee
or such agent shall deliver such Securities to or as directed by the Persons in whose names such Securities are so registered.


 




    	- 14 -



    	 



    

 


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


 


Notwithstanding
anything herein or in the forms or terms of any Securities to the contrary, none of the Issuer, the Trustee or any agent of the
Issuer or the Trustee shall be required to exchange any Unregistered Security for a Registered Security if such exchange would
result in adverse Federal income tax consequences to the Issuer (such as, for example, the inability of the Issuer to deduct from
its income, as computed for Federal income tax purposes, the interest payable on the Unregistered Securities) under then applicable
United States Federal income tax laws. The Trustee and any such agent shall be entitled to rely on an Officers’ Certificate
or an Opinion of Counsel in determining such result.


 


Neither
the Registrar nor the Issuer shall be required (i) to issue, authenticate, register the transfer of or exchange Securities of
any series for a period of 15 days before the mailing of a notice of redemption of such Securities to be redeemed or (ii) to register
the transfer of or exchange any Security selected for redemption in whole or in part.


 


Section
2.09 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall become
mutilated or defaced and shall be surrendered to the Trustee, the Issuer shall execute, and the Trustee shall authenticate and
deliver, a new Security of the same series, bearing a number not contemporaneously outstanding, in exchange and substitution for
the mutilated or defaced Security. If the Holder of any Security claims that the Security has been lost, destroyed or wrongfully
taken, the Issuer shall execute, and the Trustee shall authenticate and deliver, a new Security of the same series, bearing a
number not contemporaneously outstanding, in exchange and substitution for the lost, destroyed or wrongfully taken Security, if
the applicant so requests before the Issuer has notice that the Security has been acquired by a protected purchaser, and the applicant
furnishes to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be required
by them to indemnify and defend and to save each of them harmless and the applicant satisfies other reasonable requirements imposed
by the Issuer.


 


Upon
the issuance of any substitute Security, the Issuer 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 and its
counsel) connected therewith. In case any Security which has matured or is about to mature or has been called for redemption in
full shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer 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 or defaced Security), if
the applicant for such payment shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such
security or taking, the applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee
evidence to their satisfaction of the destruction, loss or wrongful taking of such Security and of the ownership thereof.


 




    	- 15 -



    	 



    

 


Every
substitute Security of any series issued pursuant to the provisions of this section by virtue of the fact that any such Security
is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the destroyed,
lost or wrongfully taken Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but
shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other
Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment
of mutilated, defaced or destroyed, lost or wrongfully taken Securities and shall preclude any and all other rights or remedies.


 


Section
2.10 Cancellation of Securities; Destruction Thereof. All Securities surrendered for payment, redemption, repurchase, conversion,
registration of transfer or exchange, if surrendered to the Issuer or any agent of the Issuer or the Trustee, shall be delivered
to the Trustee for cancellation or, if surrendered to the Trustee, shall be canceled by it; and no Securities shall be issued
in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled
Securities held by it in accordance with the record retention policies of the Trustee in effect from time to time and, if such
canceled certificates are destroyed, shall deliver a certificate of destruction to the Issuer. If the Issuer shall acquire any
of the Securities, 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
2.11 Temporary Securities. Pending the preparation of definitive Securities for any series, the Issuer may execute and
the Trustee shall authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise
reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as registered
Securities without coupons, of any authorized denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined
by the Issuer with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of this Indenture
as may be appropriate. Every temporary Security shall be executed by the Issuer and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay
the Issuer shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series
may be surrendered in exchange therefor without charge at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.02, and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such series

and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities
or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed

COVENANTS OF THE ISSUER AND THE TRUSTEE


 


Section
3.01 Payment of Principal and Interest. The Issuer covenants and agrees for the benefit of each series of Securities that
it will duly and punctually pay or cause to be paid the Principal of, and interest on, each of the Securities of such series at
the place or places, at the respective times and in the manner provided in such Securities. Each installment of interest on the
Securities of any series may be paid by mailing checks for such interest payable to or upon the written order of the Holders of
Securities entitled thereto as they shall appear on the registry books of the Issuer.


 


Notwithstanding
any provisions of this Indenture and the Securities of any series to the contrary, if the Issuer and a Holder of any Registered
Security so agree or if expressly provided pursuant to Section 2.03, payments of interest on, and any portion of the Principal
of, such Holder’s Registered Security shall be made by the paying agent, upon receipt from the Issuer of immediately available
funds by 11:00 a.m., New York City time (or such other time as may be agreed to between the Issuer and the paying agent) or the
Issuer, directly to the Holder of such Security (by wire transfer of Federal funds or immediately available funds or otherwise)
if the Holder has delivered written instructions to the Trustee 15 days prior to such payment date requesting that such payment
will be so made and designating the bank account to which such payments shall be so made and, in the case of payments of Principal,
surrenders the same to the Trustee. The Trustee shall be entitled to rely on the last instruction delivered by the Holder pursuant
to this Section 3.01 unless a new instruction is delivered 15 days prior to a payment date. The Issuer will indemnify and hold
each of the Trustee and any paying agent harmless against any loss, liability or expense (including attorneys’ fees and
expenses) resulting from any act or omission to act on the part of the Issuer or any such Holder in connection with any such agreement
or from making any payment in accordance with any such agreement.


 


Section
3.02 Offices for Payments, etc. So long as any of the Securities remain outstanding, the Issuer will maintain in the Borough
of Manhattan, The City of New York an office or agency (n) where the Securities may be presented for payment, (o) where the Securities
may be presented for registration of transfer and for exchange as in this Indenture provided, (p) where notices and demands to
or upon the Issuer in respect of the Securities or of this Indenture may be served and (q) for Securities of each series that
is convertible, where such Securities may be presented for conversion. The Issuer will give to the Trustee written notice of the
location of any such office or agency and of any change of location thereof. Unless otherwise specified in accordance with Section
2.03, the Issuer hereby initially designates the Corporate Trust Office of Trustee as the office to be maintained by it for each
such purpose. In case the Issuer shall fail to so designate or maintain any such office or agency or shall fail to give such notice
of the location or of any change in the location thereof, presentations and demands may be made and notices may be served at the
Corporate Trust Office.

Section
3.03 Paying Agents. Whenever the Issuer shall appoint a paying agent other than the Trustee with respect to the Securities
of any series, it will cause 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:


 


(a)
that it will hold all sums received by it as such agent for the payment of the Principal of or interest on the Securities of such
series (whether such sums have been paid to it by the Issuer or by any other obligor on the Securities of such series) in trust
for the benefit of the Holders of the Securities of such series or of the Trustee;


 


(b)
that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Securities of such series) to
make any payment of the Principal of or interest on the Securities of such series when the same shall be due and payable; and
during the continuance of the failure referred to in clause Section 3.03(b) above.


 


The
Issuer will, on or prior to each due date of the Principal of or interest on the Securities of such series, deposit with the paying
agent a sum sufficient to pay such Principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer
will promptly notify the Trustee of any failure to take such action.


 


If
the Issuer shall act as its own paying agent with respect to the Securities of any Series, it will, on or before each due date
of the Principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit of the
Holders of the Securities of such series a sum sufficient to pay such Principal or interest so becoming due. The Issuer will promptly
notify the Trustee of any failure to take such action.


 


Whenever
the Issuer shall have one or more paying agents for any series of Securities, it will, on or before each due date of the Principal
of or interest on any Securities of such series, deposit with the paying agent or agents for the Securities of such series a sum,
by 11:00 a.m. New York City time in immediately available funds on the payment date, sufficient to pay the Principal or interest
so becoming due with respect to the Securities of such series, and (unless such paying agent is the Trustee) the Issuer will promptly
notify the Trustee in writing of any failure so to act.


 


Anything
in this section to the contrary notwithstanding, the Issuer may at any time, for the purpose of obtaining a satisfaction and discharge
with respect to one or more or all series of Securities hereunder, or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust for any such series by the Issuer or any paying agent hereunder, as required by this Section, such sums
to be held by the Trustee upon the trusts herein contained.


 


Anything
in this Section 3.03 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 3.03 is
subject to the provisions of Section 9.05.

Section
3.04 Certificate of the Issuer. Within 120 days after the close of the fiscal year ended ●, and within 120 days after
the close of each fiscal year thereafter, the Issuer will furnish to the Trustee a brief certificate (which need not comply with
Section 10.05) from the principal executive, financial or accounting officer of the Issuer as to his or her knowledge of the Issuer’s
compliance with all conditions and covenants under the Indenture (such compliance to be determined without regard to any period
of grace or requirement of notice provided under the Indenture).


 


At
the time such certificate is filed, the Issuer will also file with the Trustee a letter or statement of the independent accountants
who shall have certified the financial statements of the Issuer for its preceding fiscal year to the effect that, in making the
examination necessary for certification of such financial statements, they have obtained no knowledge of any default by the Issuer
in the performance or fulfillment of any covenant, agreement or condition contained in this Indenture, which default remains uncured
at the date of such letter or statement, or, if they shall have obtained knowledge of any such uncured default, specifying in
such letter or statement such default or defaults and the nature and status thereof, it being understood that such accountants
shall not be liable directly or indirectly for failure to obtain knowledge of any such default or defaults, and that nothing contained
in this Section 3.04 shall be construed to require such accountants to make any investigation beyond the scope required in connection
with such examination.


 


Section
3.05 List of Securityholders. If and so long as the Trustee shall not be the Security registrar for the Securities of any
series, the Issuer will furnish or cause to be furnished to the Trustee a list in such form as the Trustee may reasonably require
of the names and addresses of the Holders of the Securities of such series pursuant to Section 312 of the Trust Indenture Act
of 1939 (a) semi-annually not more than 10 days after each record date for the payment of interest on such Securities, as hereinabove
specified, as of such record date and on dates to be determined pursuant to Section 2.03 for non-interest bearing Securities in
each year and (b) at such other times as the Trustee may request in writing, within 30 days after receipt by the Issuer of any
such request as of a date not more than 10 days prior to the time such information is furnished.


 


Section
3.06 Reports by the Issuer. The Issuer covenants to:


 


(a)
file, whether or not required to do so under applicable law, with the Trustee, within 15 days after the Issuer files the same
with the Commission:


 


(i)
copies of the annual reports and of the information, documents, and other reports which the Issuer files with the Commission pursuant
to Section 13 or Section 15(d) of the Securities Exchange Act of 1934; and


 


(ii)
such additional information, documents and reports with respect to compliance by the Issuer with the conditions and covenants
provided for in this Indenture as the Issuer may from time to time file with the Commission; and


 


(b)
transmit to the Securityholders, in the manner and to the extent provided in Section 10.04, such summaries of any information,
documents and reports required to be filed with the Trustee pursuant to the provisions of subdivision (a) of this Section 3.06
as may be required by the rules and regulations of the Commission.


 




    	- 19 -



    	 



    

 


Delivery
of such reports, information and documents to the Trustee is 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 Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers’ Certificates).


 


Section
3.07 Corporate Existence. So long as any of the Securities remain unpaid, the Issuer will at all times (except as otherwise
provided or permitted elsewhere in this Indenture) do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence.


 


Section
3.08 Restrictions on Mergers, Sales and Consolidations. So long as any of the Securities remain unpaid, the Issuer will
not consolidate or merge with or sell, convey or lease all or substantially all of its property to any other corporation except
as permitted in Article 8 hereof.


 


Section
3.09 Further Assurances. From time to time whenever requested by the Trustee, the Issuer will execute and deliver such
further instruments and assurances and do such further acts as may be reasonably necessary or proper to carry out more effectually
the purposes of this Indenture or to secure the rights and remedies hereunder of the Holders of the Securities of any series.

default hereunder;


 




    	- 20 -



    	 



    

 


(d)
the entry by a court having jurisdiction in the premises of a decree or order for relief in respect of the Issuer in an involuntary
case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or the appointment of a receiver,
liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for any substantial part of the

(f)
any other Event of Default provided in the supplemental indenture or resolution of the Board of Directors under which such series
of Securities is issued or in the form of Security for such series.


 


If
an Event of Default described in clauses 4.01(a), 4.01(b), 4.01(c) or 4.01(f) occurs and is continuing, then, and in each and
every such case, unless the Principal of all of the Securities of such 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 any affected series then Outstanding
hereunder (each such series voting as a separate class) by notice in writing to the Issuer (and to the Trustee if given by Securityholders),
may declare the entire Principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of
the Principal amount as may be specified in the terms of such series) of all Securities of such series and the interest accrued
thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable.
If an Event of Default described in clauses Section 4.01(d) or Section 4.01(e) occurs and is continuing, then the Principal amount

    	- 21 -



    	 



    

 


The
foregoing provisions, however, are subject to the condition that if, at any time after the Principal (or, if the Securities are
Original Issue Discount Securities, such portion of the Principal as may be specified in the terms thereof) of the Securities
of any series (or of all the Securities, as the case may be) shall have been so declared due and payable, and before any judgment
or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Issuer shall pay
or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Securities of such
series (or of all the Securities, as the case may be) and the Principal of any and all Securities of such series (or of all the
Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest upon such Principal
and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at
the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the
Securities of such series (or at the respective rates of interest or Yields to Maturity of all the Securities, as the case may
be) to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee except
as a result of negligence or bad faith, and if any and all Events of Default under the Indenture, other than the non-payment of
the Principal of Securities which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as
provided herein, then and in every such case the Holders of a majority in aggregate Principal amount of all the then Outstanding
Securities of all such series that have been accelerated, each such series voting as a separate class, by written notice to the
Issuer and to the Trustee, may waive all defaults with respect to such series (or with respect to all the Securities, as the case
may be) and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend
to or shall affect any subsequent default or shall impair any right consequent thereon.


 


For
all purposes under this Indenture, if a portion of the Principal of any Original Issue Discount Securities shall have been accelerated
and declared due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration
has been rescinded and annulled, the Principal amount of such Original Issue Discount Securities shall be deemed, for all purposes
hereunder, to be such Portion of the Principal thereof as shall be due and payable as a result of such acceleration, and payment
of such portion of the Principal thereof as shall be due and payable as a result of such acceleration, together with interest,
if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities.


 


Section
4.02 Collection of Indebtedness by Trustee; Trustee May Prove Debt. The Issuer covenants that (h) in case default shall
be made in the payment of any installment of interest on any of the Securities of any series when such interest shall have become
due and payable, and such default shall have continued for a period of 30 days or (i) in case default shall be made in the payment
of all or any part of the Principal of any of the Securities of any series when the same shall have become due and payable, whether
upon maturity of the Securities of such series or upon any redemption or by declaration or otherwise, then in each case upon demand
of the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series (x) the whole
amount that then shall have become due and payable on all Securities of such series for Principal or interest, as the case may
be (with interest to the date of such payment upon the overdue Principal and, to the extent that payment of such interest is enforceable
under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such series) and (y) in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee
and each predecessor Trustee, their respective agents and counsel, and any expenses and liabilities incurred, and all advances

Until
such demand is made by the Trustee, the Issuer may pay the Principal of and interest on the Securities of any series to the registered
Holders, whether or not the Principal of and interest on the Securities of such series be overdue.

trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums
so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment

to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor Trustee,
and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances
made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Securityholders allowed

property of the Issuer or such other obligor;


 


(b)
unless prohibited by applicable law and regulations, to vote on behalf of the Holders of the Securities of any series in any election

in the event that the Trustee shall consent to the making of payments directly to the Securityholders, to pay to the Trustee such
amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective
agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee except as a result of negligence or bad faith and all other amounts due to the Trustee or any predecessor
Trustee pursuant to Section 5.06.

rights of action and of asserting claims under this Indenture, or under any of the Securities, may be enforced by the Trustee
without the possession of any of the Securities or the production thereof on any trial or other proceedings relative thereto,
and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor
Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Securities in respect
of which such action was taken.


 


In

to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Securities in respect to
which such action was taken, and it shall not be necessary to make any Holders of such Securities parties to any such proceedings.

Section
4.06 Limitations on Suits by Securityholder. 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 action or proceeding at law or in equity or in bankruptcy or otherwise
upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other
similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice
of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also 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 or proceedings in respect of such Event of Default in its own name as trustee hereunder and shall have
offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred therein
or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute
any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant
to Section 4.09; it being understood and intended, and being expressly covenanted by the Holder of every Security with every other
Holder and the Trustee, that no one or more Holders of Securities of any series shall have any right in any manner whatever by
virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of
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

any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.


 


Section
4.08 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided in Section 4.06, no right
or remedy herein conferred upon or reserved to the Trustee or to the Securityholders is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of
any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate
right or remedy.


 


No
delay or omission of the Trustee or of any Securityholder 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 Event of Default
or an acquiescence therein; and, subject to Section 4.06, every power and remedy given by this Indenture or by law to the Trustee
or to 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
4.09 Control by Securityholders. The Holders of a majority in aggregate Principal amount of the Securities of each series
affected (with each series voting as a separate class) at the time outstanding shall have the right to direct the time, method,
and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture; provided that such direction shall not be otherwise
than in accordance with law and the provisions of this Indenture and provided further that (subject to the provisions of Section
5.01) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of
directors, the executive committee, or a trust committee of directors or Responsible Officers of the Trustee shall determine that
the action or proceedings so directed would subject the Trustee to personal liability or if the Trustee in good faith shall so
determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests
of Holders of the Securities of all series so affected not joining in the giving of said direction.

Nothing
in this Indenture shall impair the right of the Trustee to take any action which is not inconsistent with such direction or directions
by Securityholders.


 


Section
4.10 Waiver of Past Defaults. Prior to a declaration of the acceleration of the maturity of the Securities of any series
as provided in Section 4.01, the Holders of a majority in aggregate Principal amount of the Securities of such series at the time
Outstanding (each such series voting as a separate class) may on behalf of the Holders of all the Securities of such series waive
an existing default or Event of Default, except a default in the payment of Principal of or interest on any Security as specified
in clauses (a) or (b) of Section 4.01 or in respect of a covenant or provision hereof which cannot be modified or amended without
the consent of each Holder affected as provided in Section 7.02. In the case of any such waiver, the Issuer, the Trustee and the
Holders of the Securities of each series affected shall be restored to their former positions and rights hereunder, respectively.


 


Upon
any such waiver, such default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of
Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but
no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.


 


Section
4.11 Trustee to Give Notice of Default, But May Withhold in Certain Circumstances. The Trustee shall give to the Securityholders
of any series, as the names and addresses of such Holders appear on the registry books, notice by mail of all defaults known to
Responsible Officers of the Trustee which have occurred with respect to such series, such notice to be transmitted within 90 days
after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default”
or “defaults” for the purposes of this section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the
payment of the Principal of or interest on any of the Securities of such series, the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or
Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders
of such series.


 


Section
4.12 Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder
of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any
suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
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; provided that the provisions of this Section 4.12 shall not apply to (i) any suit instituted by the Trustee, (ii)
any suit instituted by any Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in
aggregate Principal amount of the Securities of such series or (iii) any suit instituted by a Holder pursuant to Section 4.07.

CONCERNING THE TRUSTEE


 


Section
5.01 Duties and Responsibilities of the Trustee. With respect to the Holders of any series of Securities issued hereunder,
the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a particular series and after the
curing or waiving of all Events of Default which may have occurred with respect to such series, undertakes to perform such duties
and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities
of a series has occurred (which has not been cured or waived) the Trustee shall exercise such of the rights and powers vested
in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use
under the circumstances in the conduct of such person’s own affairs.


 


(a)
Prior to the occurrence of an Event of Default with respect to the Securities of any series and after the curing or waiving of
all such Events of Default with respect to such series which may have occurred:


 


(i)
the duties and obligations of the Trustee with respect to the Securities of any Series shall be determined solely by the express
provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as
are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against
the Trustee; and


 


(ii)
in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but in the case of any such statements, 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.


 


(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 5.01;


 






    	- 28 -



    	 



    

 


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


 


(iii)
the Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance
with the direction of the Holders 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.


 


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 shall
be reasonable ground for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably
assured to it.


 


The
provisions of this Section 5.01 are in furtherance of and subject to Sections 315 and 316 of the Trust Indenture Act of 1939.


 


Whether
or not therein expressly provided, every provision of this Indenture relating to the conduct of, affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 5.01.


 


Section
5.02 Certain Rights of the Trustee. In furtherance of and subject to the Trust Indenture Act of 1939, and subject to Section
5.01:


 


(a)
In the absence of bad faith on its part, the Trustee may conclusively rely and shall be protected in acting or refraining from
acting upon any resolution, Officers’ Certificate or any other certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, coupon, 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 Issuer mentioned herein shall be sufficiently evidenced by an Officers’ Certificate
(unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may
be evidenced to the Trustee by a copy thereof certified by the secretary or an assistant secretary of the Issuer;


 


(c)
the Trustee may consult with counsel of its selection and any advice or Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance
with such advice or Opinion of Counsel;


 


(d)
the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request,
order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall
have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred
by it in connection with such request, order or direction;


 




    	- 29 -



    	 



    

 


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


 


(f)
prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, 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, appraisal, bond, debenture, note, coupon, security, or other paper
or document unless requested in writing so to do by the Holders of not less than a majority in aggregate Principal amount of the
Securities of all series affected then outstanding; provided 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 indemnity
satisfactory to it against such expenses or liabilities as a condition to proceeding, and the reasonable expenses of every such
investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer
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 not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the
part of any such agent or attorney appointed with due care by it hereunder;


 


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


 


(i)
the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee
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; and


 


(k)
the Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the names of individuals and/or titles
of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may
be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in
any such certificate previously delivered and not superseded.


 


Section
5.03 Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds Thereof. The recitals contained
herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the
Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or the Securities. The Trustee shall not be accountable for the use or application by
the Issuer of any of the Securities or of the proceeds thereof.


 




    	- 30 -



    	 



    

 


Section
5.04 Trustee and Agents May Hold Securities; Collections, etc. The Trustee or any agent of the Issuer or the Trustee, in
its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were
not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such agent.


 


Section
5.05 Monies Held by Trustee. All monies received by the Trustee in trust hereunder need not be segregated from other funds
except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall
be under any liability for interest on any monies received by it hereunder.


 


Section
5.06 Compensation and Indemnification of Trustee and Its Prior Claim. The Issuer covenants and agrees to pay to the Trustee
from time to time, and the Trustee shall be entitled to, such compensation as shall be agreed in writing from time to time by
the Issuer and the Trustee (which shall not be limited by any provision of law in regard to the compensation of a trustee of an
express trust) and the Issuer covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it 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 agents and
other persons not regularly in its employ) except to the extent any such expense, disbursement or advance may arise from its negligence
or bad faith. The Issuer also covenants and agrees to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless
against, any loss, liability or expense arising out of or in connection with the acceptance or administration of this Indenture
or the trusts hereunder and the performance of its duties hereunder, including the costs and expenses of defending itself against
or investigating any claim of liability (whether asserted by the Issuer, a Holder or any other Person) in the premises, except
to the extent such loss, liability or expense is due to the negligence or bad faith of the Trustee or such predecessor Trustee.
The obligations of the Issuer under this section to compensate and indemnify the Trustee and each predecessor Trustee and to pay
or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. Such
additional indebtedness shall be a senior claim and lien to that of the Securities upon all property and funds held or collected
by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities
are hereby subordinated to such senior claim. The parties agree that if the Trustee renders services following an Event of Default
under Section 4.01(d) or 4.01(e), compensation for such services is intended to constitute administrative expense under any bankruptcy
law.


 




    	- 31 -



    	 



    

 


Section
5.07 Right of Trustee to Rely on Officers’ Certificate, etc. Subject to Section 5.01 and 5.02, whenever in the administration
of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior
to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers’ Certificate delivered to the Trustee, and such certificate, in the absence of negligence or
bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under
the provisions of this Indenture upon the faith thereof.


 


Section
5.08 Persons Eligible for Appointment as Trustee. The Trustee for each series of Securities hereunder shall at all times
be a corporation which is eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939 and
which has (or which is a Wholly-Owned Subsidiary, directly or indirectly, of a bank holding company which has) a combined capital
and surplus of $50,000,000. If such corporation or holding company publishes reports of condition at least annually, pursuant
to law or to the requirements of a Federal, State or District of Columbia supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such corporation or holding company shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.


 


Section
5.09 Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed,
may at any time resign with respect to one or more or all series of Securities by giving written notice of resignation to the
Issuer. Upon receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee or trustees with respect
to the applicable series by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor Trustee
shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such
notice of resignation, the resigning Trustee may petition, at the expense of the Issuer, any court of competent jurisdiction for
the appointment of a successor Trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities of the
applicable series for at least six months may, subject to the provisions of Section 4.12, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor Trustee. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, appoint a successor Trustee.


 


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


 


(i)
the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act of 1939 with respect to any
series of Securities after written request therefor by the Issuer or by any Securityholder who has been a bona fide Holder of
a Security or Securities of such series for at least six months;


 


(ii)
the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939
and shall fail to resign after written request therefor by the Issuer or by any Securityholder; or


 




    	- 32 -



    	 



    

 


(iii)
the Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged a bankrupt or insolvent,
or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; then, in any such
case, the Issuer may remove the Trustee with respect to the applicable series of Securities and appoint a successor trustee for
such series by written instrument, in duplicate, executed by order of the Board of Directors of the Issuer, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee, or, subject to Section 315(e) of
the Trust Indenture Act of 1939, any Securityholder who has been a bona fide Holder of a Security or Securities of such series
for at least six months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee with respect to such series. 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 each series at the time outstanding may at any time
remove the Trustee with respect to Securities of such series and appoint a successor Trustee with respect to the Securities of
such series by delivering to the Trustee so removed, to the successor Trustee so appointed and to the Issuer the evidence provided
in Section 6.01 of the action in that regard taken by the Securityholders.


 


(d)
Any resignation or removal of the Trustee with respect to any series and any appointment of a successor trustee with respect to
such series pursuant to any of the provisions of this Section 5.09 shall become effective upon acceptance of appointment by the
successor trustee as provided in Section 5.10.


 


Section
5.10 Acceptance of Appointment by Successor. Any successor Trustee appointed as provided in Section 5.09 shall execute
and deliver to the Issuer and to its predecessor Trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor Trustee with respect to all or any applicable series shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as if originally named as Trustee for such series hereunder.
On the written request of the Issuer or of the successor Trustee, upon payment of its charges then unpaid, the Trustee ceasing
to act shall, subject to Section 5.06, pay over to the successor Trustee all monies at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor Trustee all such rights, powers, duties and obligations. Upon
request of any such successor Trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly
vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless,
retain a prior claim upon all property or funds held or collected by such Trustee to secure any amounts then due it pursuant to
the provisions of Section 5.06.


 


If
a successor Trustee is appointed with respect to the Securities of one or more (but not all) series, the Issuer, the predecessor
Trustee and each successor Trustee with respect to the Securities of any applicable series shall execute and deliver an indenture
supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor
Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees
of the same trust and that each such Trustee shall be Trustee of a trust or trusts under separate indentures.


 




    	- 33 -



    	 



    

 


Upon
acceptance of appointment by any successor Trustee as provided in this Section 5.10, the Issuer shall mail notice thereof by first-class
mail to the Holders of Securities of any series for which such successor Trustee is acting as Trustee at their last addresses
as they shall appear in the Security register. If the acceptance of appointment is substantially contemporaneous with the resignation,
then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.09. If the Issuer
fails to mail such notice within 10 days after acceptance of appointment by the successor Trustee, the successor Trustee shall
cause such notice to be mailed at the expense of the Issuer.


 


Section
5.11 Merger, Conversion, Consolidation or Succession to Business of Trustee. 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 the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be eligible under the provisions
of Section 5.08, 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 at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities of
any series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication
of any predecessor Trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities of any
series shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full
force which it is anywhere in the Securities of such series or in this Indenture provided that the certificate of the Trustee
shall have; provided, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate
Securities of any series in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion
or consolidation.


 


Section
5.12 Reports to the Trustee. The Trustee shall transmit to Holders such reports concerning the Trustee and its actions
under this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto.
If required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within sixty days after each May 15 following the
date of the initial issuance of Securities under this Indenture deliver to Holders a brief report, dated as of such May 15, which
complies with the provisions of such Section 313(a).


 


A
copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange,
if any, upon which the Securities are listed, with the Commission and with the Issuer. The Issuer will promptly notify the Trustee
when the Securities are listed on any stock exchange and of any delisting thereof.

CONCERNING
THE SECURITYHOLDERS


 


Section
6.01 Evidence of Action Taken by Securityholders. Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified percentage in Principal amount of the Securityholders
of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such
specified percentage of Securityholders in person or by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution
of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject
to Section 5.01 and 5.02) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Article.


 


Section
6.02 Proof of Execution of Instruments and of Holding of Securities; Record Date. Subject to Section 5.01 and 5.02, the
execution of any instrument by a Securityholder or his agent or proxy may be proved by the certificate of any notary public or
other officer authorized to take acknowledgment of deeds, that the Person executing such instrument acknowledged to such notary
public or other such officer the execution thereof, or by an affidavit of a witness to such execution sworn to before any such
notary public or other officer. Where such execution is by an officer of a corporation or association or a member of a partnership
on behalf of such corporation, association or partnership, as the case may be, or by any other Person acting in a representative
capacity, such certificate or affidavit shall also constitute sufficient proof of such Person’s authority. The holding of
Securities shall be proved by the Security register or by a certificate of the registrar thereof. The Issuer may set a record
date for purposes of determining the identity of Holders of Securities of any series entitled to vote or consent to any action
referred to in Section 6.01, which record date may be set at any time or from time to time by notice to the Trustee, for any date
or dates (in the case of any adjournment or reconsideration) not more than 60 days nor less than five days prior to the proposed
date of such vote or consent, and thereafter, notwithstanding any other provisions hereof, only Holders of Securities of such
series of record on such record date shall be entitled to so vote or give such consent or revoke such vote or consent.


 


Section
6.03 Holders to be Treated as Owners. Prior to due presentment of a Security for registration of transfer, the Issuer,
the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name any Security shall be registered
upon the Security register for such series as the absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account
of the Principal of and, subject to the provisions of this Indenture, interest on such Security and for all other purposes, and
neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be affected by any notice to the contrary.
All such payments so made to any such person, or upon his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any such Security.


 




    	- 35 -



    	 



    

 


Section
6.04 Securities Owned by Issuer Deemed Not Outstanding. In determining whether the Holders of the requisite aggregate Principal
amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under this Indenture,
Securities which are owned by the Issuer or any other obligor on the Securities with respect to which such determination is being
made or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Issuer or any other obligor on the Securities with respect to which such determination is being made 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 as to which the Trustee has received
written notice are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded
as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect
to such Securities and that the pledgee is not the Issuer or any other obligor upon the Securities or any person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities.
In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee
in accordance with such advice. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’
Certificate listing and identifying all Securities, if any, known by the Issuer to be owned or held by or for the account of any
of the above-described persons; and, subject to Section 5.01 and 5.02, the Trustee shall be entitled to accept such Officers’
Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding
for the purpose of any such determination.


 


Section
6.05 Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided
in Section 6.01, of the taking of any action by the Holders of the percentage in aggregate Principal amount of the Securities
of any or all series, as the case may be, specified in this Indenture in connection with such action, any Holder of a Security

the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 6.01,

CONSOLIDATION,
MERGER, SALE OR CONVEYANCE


 


Section
8.01 Issuer May Consolidate, etc., on Certain Terms. The Issuer covenants that it will not merge or consolidate with any
other Person or sell, convey, transfer, lease or otherwise dispose of all or substantially all of its property and assets to any
Person (other than a consolidation with or merger with or into or a sale, conveyance, transfer, lease or other disposition to
a Wholly-Owned Subsidiary with a positive net worth; provided that, in connection with any such merger of the Issuer with
a Wholly-Owned Subsidiary, no consideration (other than common stock) in the surviving person or the Issuer shall be issued or
distributed to the stockholders of the Issuer), unless (xiv) either (x) the Issuer shall be the continuing corporation, or the
successor corporation or (y) the Person formed by such consolidation or into which the Issuer is merged or that acquires by sale
or conveyance substantially all the assets of the Issuer (if other than the Issuer) shall be a corporation or limited liability
company organized and validly existing under the laws of the United States of America or any jurisdiction thereof and shall expressly
assume the due and punctual payment of the Principal of and interest on all the Securities, according to their tenor, and the
due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed
by the Issuer, by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such Person, (xv)
immediately after giving effect to such transaction, no default or Event of Default shall have occurred and be continuing and
(xvi) the Issuer delivers to the Trustee an Officers’ Certificate and Opinion of Counsel, in each case stating that such
consolidation, merger or transfer and such supplemental indenture complies with this Section 8.01 and that all conditions precedent
provided for herein relating to such transaction have been complied with; provided, however, that the foregoing
limitations shall not apply if, in the good faith determination of the Board of Directors, whose determination shall be evidenced
by a board resolution certified to the Trustee, the principal purpose of such transaction is to change the state of incorporation
of the Issuer; and provided further that any such transaction shall not have as one of its purposes the evasion of the
foregoing limitations.


 


Section
8.02 Successor Corporation Substituted. In case of any such consolidation, merger, sale, conveyance, transfer, lease or
other disposition, and following such an assumption by the successor Person, such successor Person shall succeed to and be substituted
for the Issuer, with the same effect as if it had been named herein. Such successor Person may cause to be signed, and may issue
either in its own name or in the name of the Issuer prior to such succession any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor Person
instead of the Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee, pursuant
to the terms hereof, shall authenticate and shall deliver any Securities which previously shall have been signed and delivered
by the officers of the Issuer to the Trustee for authentication, and any Securities which such successor Person thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

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


 


Upon
the assumption by the successor Person in the manner described in this Article, the Issuer shall be discharged from all obligations
and covenants under this Indenture and the Securities.

or mailing) any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders
entitled to such money must look to the Issuer for payment as general creditors unless an abandoned property law designates another
Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

as such, of the Issuer or of any successor Person thereof, either directly or through the Issuer or any successor Person thereof,
under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable
proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the Holders
thereof and as part of the consideration for the issue of the Securities.


 


Section
10.02 Provisions of Indenture for the Sole Benefit of Parties and Securityholders. Nothing in this Indenture or in the
Securities, expressed or implied, shall give or be construed to give to any person, firm or corporation, other than the parties

or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties
hereto and their successors and of the Holders of the Securities.

respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise
of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar
as it relates to factual matters, information with respect to which is in the possession of the Issuer, upon the certificate,

accounting matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise
of reasonable care should know that the same are erroneous.

Article

REDEMPTION
OF SECURITIES


 


Section
11.01 Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which
are redeemable before their maturity except as otherwise specified as contemplated by Section 2.03 for Securities of such series.


 


Section
11.02 Notice of Redemption; Partial Redemptions. Notice of redemption to the Holders of Securities of any series to be
redeemed as a whole or in part at the option of the Issuer shall be given by mailing notice of such redemption by first class
mail, postage prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such Holders of Securities
of such series at their last addresses as they shall appear upon the registry books. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure
to give notice by mail, or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.


 


The
notice of redemption to each such Holder shall specify the CUSIP numbers of such Securities to be redeemed, the Principal amount
of each Security of such series held by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place
or places of payment, that payment will be made upon presentation and surrender of such Securities, that interest accrued to the
date fixed for redemption will be paid as specified in such notice and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part only the notice
of redemption shall state the portion of the Principal amount thereof to be redeemed, the method the Trustee shall use to determine
such Securities to be redeemed as specified in the last paragraph of this Section 11.02, if applicable, and shall state that on
and after the date fixed for redemption, 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.


 


The
notice of redemption of Securities of any series to be redeemed at the option of the Issuer shall be given by the Issuer or, at
the Issuer’s written request, by the Trustee in the name and at the expense of the Issuer.


 


By
11:00 a.m. (New York City time) on the redemption date specified in the notice of redemption given as provided in this Section,
the Issuer will deposit with the Trustee or with one or more paying agents (or, if the Issuer is acting as its own paying agent,
set aside, segregate and hold in trust as provided in Section 3.03) an amount of money sufficient to redeem on the redemption
date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest
to the date fixed for redemption. If less than all the outstanding Securities of a series are to be redeemed, the Issuer will
deliver to the Trustee at least 70 days (unless a shorter period shall be satisfactory to the Trustee) prior to the date fixed
for redemption an Officers’ Certificate stating the aggregate Principal amount of Securities to be redeemed.


 




    	- 47 -



    	 



    

 


In
the case of the redemption of all of the Securities of a series outstanding, the Issuer shall notify the Trustee in writing of
the redemption date 45 days (unless a shorter period shall be satisfactory to the Trustee) prior to the redemption date.


 


If
less than all the Securities of a series are to be redeemed, the Trustee shall select, pro rata or by lot or in such manner as
it shall deem appropriate and fair, Securities of such series to be redeemed in whole or in part. Securities of a series may be
redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any multiple thereof.
The Trustee shall promptly notify the Issuer in writing of the Securities of such series selected for redemption and, in the case
of any Securities of such series selected for partial redemption, the Principal amount thereof to be redeemed. For all purposes
of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities of any series
shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the Principal amount of such
Security which has been or is to be redeemed.


 


Section
11.03 Payment of Securities Called for Redemption. If notice of redemption has been given as above provided, the Securities
or portions of Securities 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 on and after said date
(unless the Issuer shall default in the payment of such Securities at the redemption price, together with interest accrued to
said date) interest on the Securities or portions of Securities so called for redemption shall cease to accrue and, except as
provided in Section 5.05 and 9.04, such Securities shall cease from and after the date fixed for redemption to be entitled to
any benefit or security under this Indenture, and the Holders thereof shall have no right in respect of such Securities except
the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender
of such Securities at a place of payment specified in said notice, said Securities or the specified portions thereof shall be
paid and redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon to the date fixed for
redemption; provided that any semiannual payment of interest becoming due on the date fixed for redemption shall be payable to
the Holders of such Securities registered as such on the relevant record date subject to the terms and provisions of Section 2.07
hereof.


 


If
any Security called for redemption shall not be so paid upon surrender thereof for redemption, the Principal shall, until paid
or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case
of an Original Issue Discount Security) borne by the Security.


 


Upon
presentation of any Security redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to
or on the order of the Holder thereof, at the expense of the Issuer, a new Security or Securities of such series, of authorized
denominations, in Principal amount equal to the unredeemed portion of the Security so presented, pursuant to Section 2.04, 2.05
and 2.06.


 




    	- 48 -



    	 



    

 


Section
11.04 Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from
eligibility for selection for redemption if they are identified by registration and certificate number in a written statement
signed by an authorized officer of the Issuer and delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer
or (b) an entity specifically identified in such written statement directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuer.


 


Section
11.05 Conversion Arrangement On Call For Redemption. In connection with any redemption of Securities, the Issuer shall
deposit the amount due in connection with such redemption as required by Section 11.02 or it may arrange for the purchase and
conversion of any Securities called for redemption by an agreement with one or more investment bankers or other purchasers to
purchase such Securities and to make the deposit required of it by Section 11.02 on its behalf by paying to the Trustee or the
Paying Agent in trust for the Securityholders, on or before 10:00 a.m. New York time on the redemption date, an amount no less
than the redemption price, together with interest, if any, accrued to the redemption date of such Securities, in immediately available
funds. Notwithstanding anytime to the contrary contained in this Article 11, the obligation of the Issuer to pay the redemption
price of such Securities, including all accrued interest, if any, shall be deemed to be satisfied and discharged to the extent
such amount is so paid by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion
by the Holders thereof may, at the option of the Issuer, be deemed, to the fullest extent permitted by law, acquired by such purchasers
from such Holders and (notwithstanding anything to the contrary contained in Article 12) surrendered by such purchasers for conversion,
all as of immediately prior to the close of business on the last day on which Securities of such series called for redemption
may be converted in accordance with this Indenture and the terms of such Securities, subject to payment of the above amount aforesaid.
The Trustee or the Paying Agent shall hold and pay to the Securityholders whose Securities are selected for redemption any such
amount paid to it in the same manner as it would monies deposited with it by the Issuer for the redemption of Securities. Without
the Trustee’s and the Paying Agent’s prior written consent, no arrangement between the Issuer and such purchasers
for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities
or obligations of the Trustee as set forth in this Indenture, and the Issuer agrees to indemnify the Trustee from, and hold it
harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and
conversion of any Securities between the Issuer and such purchasers, including the costs and expenses incurred by the Trustee
and the Paying Agent in the defense of any claim or liability arising out of or in connection with the exercise or performance
of any of its powers, duties, responsibilities or obligations under this Indenture.


 


Article
12


CONVERSION
OF SECURITIES


 


Section
12.01 Applicability of Article. Securities of any series which are convertible into Capital Stock at the option of the
Securityholder shall be convertible in accordance with their terms and (unless otherwise specified as contemplated by Section
2.03 for Securities of any series) in accordance with this Article. Each reference in this Article 12 to “a Security”
or “the Securities” refers to the Securities of the particular series that is convertible into Capital Stock. Each
reference in this Article to “Capital Stock” into which Securities of any series are convertible refers to the class
of Capital Stock into which the Securities of such series are convertible in accordance with their terms (as specified as contemplated
by Section 2.03). If more than one series of Securities with conversion privileges are outstanding at any time, the provisions
of this Article 12 shall be applied separately to each such series.


 




    	- 49 -



    	 



    

 


Section
12.02 Right of Securityholders to Convert Securities. Subject to and upon compliance with the terms of the Securities and
the provisions of Section 11.05 and this Article 12, at the option of the Holder thereof, any Security of any series of any authorized
denomination, or any portion of the Principal amount thereof which is $1,000 or any integral multiple of $1,000, may, at any time
during the period specified in the Securities of such series, or in case such Security or portion thereof shall have been called
for redemption, then in respect of such Security or portion thereof until and including, but not after (unless the Issuer shall
default in payment due upon the redemption thereof) the close of business on the Business Day prior to the date fixed for redemption
except that in the case of redemption at the option of the Securityholder, if specified in the terms of such Securities, such
right shall terminate upon receipt of written notice of the exercise of such option, be converted into duly authorized, validly
issued, fully paid and nonassessable shares of Capital Stock, as specified in such Security, at the conversion rate for each $1,000
Principal amount of Securities (such initial conversion rate reflecting an initial conversion price specified in such Security)
in effect on the conversion date, or, in case an adjustment in the conversion rate has taken place pursuant to the provisions
of Section 12.05, then at the applicable conversion rate as so adjusted, upon surrender of the Security or Securities, the Principal
amount of which is so to be converted, to the Issuer at any time during usual business hours at the office or agency to be maintained
by it in accordance with the provisions of Section 3.02, accompanied by a written notice of election to convert as provided in
Section 12.03 and, if so required by the Issuer and the Trustee, by a written instrument or instruments of transfer in form satisfactory
to the Issuer and the Trustee duly executed by the registered Holder or his attorney duly authorized in writing. All Securities
surrendered for conversion shall, if surrendered to the Issuer or any conversion agent, be delivered to the Trustee for cancellation
and cancelled by it, or shall, if surrendered to the Trustee, be cancelled by it, as provided in Section 2.10.


 


The
initial conversion price or conversion rate in respect of a series of Securities shall be as specified in the Securities of such
series. The conversion price or conversion rate will be subject to adjustment on the terms set forth in Section 12.05 or such
other or different terms, if any, as may be specified by Section 2.03 for Securities of such series. Provisions of this Indenture
that apply to conversion of all of a Security also apply to conversion of a portion of it.


 


Section
12.03 Issuance of Shares of Capital Stock on Conversion. As promptly as practicable after the surrender, as herein provided,
of any Security or Securities for conversion, the Issuer shall deliver or cause to be delivered at its said office or agency to
or upon the written order of the Holder of the Security or Securities so surrendered a certificate or certificates representing
the number of duly authorized, validly issued, fully paid and nonassessable shares of Capital Stock into which such Security or
Securities may be converted in accordance with the terms thereof and the provisions of this Article 12. Prior to delivery of such
certificate or certificates, the Issuer shall require a written notice at its said office or agency from the Holder of the Security
or Securities so surrendered stating that the Holder irrevocably elects to convert such Security or Securities, or, if less than
the entire Principal amount thereof is to be converted, stating the portion thereof to be converted. Such notice shall also state
the name or names (with address and social security or other taxpayer identification number) in which said certificate or certificates
are to be issued. Such conversion shall be deemed to have been made at the time that such Security or Securities shall have been
surrendered for conversion and such notice shall have been received by the Issuer or the Trustee, the rights of the Holder of
such Security or Securities as a Securityholder shall cease at such time, the person or persons entitled to receive the shares
of Capital Stock upon conversion of such Security or Securities shall be treated for all purposes as having become the record
holder or holders of such shares of Capital Stock at such time and such conversion shall be at the conversion rate in effect at
such time. In the case of any Security of any series which is converted in part only, upon such conversion, the Issuer shall execute
and the Trustee shall authenticate and deliver to the Holder thereof, as requested by such Holder, a new Security or Securities
of such series of authorized denominations in aggregate Principal amount equal to the unconverted portion of such Security.


 




    	- 50 -



    	 



    

 


If
the last day on which a Security may be converted is not a Business Day in a place where a conversion agent is located, the Security
may be surrendered to that conversion agent on the next succeeding day that is a Business Day.


 


The
Issuer will not be required to deliver certificates for shares of Capital Stock upon conversion while its stock transfer books
are closed for a meeting of shareholders or for the payment of dividends or for any other purpose, but certificates for shares
of Capital Stock shall be delivered as soon as the stock transfer books shall again be opened.


 


Section
12.04 No Payment or Adjustment for Interest or Dividends. Unless otherwise specified as contemplated by Section 2.03 for
Securities of such series, Securities surrendered for conversion during the period from the close of business on any regular record
date (or special record date for payment of defaulted interest) next preceding any interest payment date to the opening of business
on such interest payment date (except Securities called for redemption on a redemption date within such period) when surrendered
for conversion must be accompanied by payment of an amount equal to the interest thereon which the registered Holder is to receive
on such interest payment date. Payment of interest shall be made, as of such interest payment date or such date, as the case may
be, to the Holder of record of the Securities as of such regular, or special record date, as applicable. Except where Securities
surrendered for conversion must be accompanied by payment as described above, no interest on converted Securities will be payable
by the Issuer on any interest payment date subsequent to the date of conversion. No other payment or adjustment for interest or
dividends is to be made upon conversion. Notwithstanding the foregoing, upon conversion of any Original Issue Discount Security,
the fixed number of shares of Capital Stock into which such Security is convertible delivered by the Issuer to the Holder thereof
shall be applied, first, to pay the accrued original issue discount attributable to the period from the date of issuance to the
date of conversion of such Security, and, second, to pay the balance of the Principal amount of such Security.


 


Section
12.05 Adjustment of Conversion Rate. Unless otherwise specified as contemplated by Section 2.03 for Securities of such
series, the conversion rate for Securities in effect at any time shall be subject to adjustment as follows:


 




    	- 51 -



    	 



    

 


(a)
In case the Issuer shall (i) declare a dividend or make a distribution on the class of Capital Stock into which Securities of
such series are convertible in shares of its Capital Stock, (ii) subdivide the outstanding shares of the class of Capital Stock
into which Securities of such series are convertible into a greater number of shares, (iii) combine the outstanding shares of
the class of Capital Stock into which Securities of such series are convertible into a smaller number of shares or (iv) issue
by reclassification of the shares of the class of Capital Stock into which Securities of such series are convertible (including
any such reclassification in connection with a consolidation or merger in which the Issuer is the continuing corporation) any
shares, the conversion rate for the Securities of such series in effect at the time of the record subdivision, combination or
reclassification, shall be proportionately adjusted so that the Holder of any Security of such series surrendered for conversion
after such time shall be entitled to receive the number and kind of shares which he would have owned or have been entitled to
receive had such Security been converted immediately prior to such time. Similar adjustments shall be made whenever any event
listed above shall occur.


 


(b)
In case the Issuer shall fix a record date for the issuance of rights or warrants to all holders of the class of Capital Stock
into which Securities of such series are convertible entitling them (for a period expiring within 45 days after such record date)
to subscribe for or purchase shares of such class of Capital Stock (or securities convertible into shares of such class of Capital
Stock) at a price per share (or, in the case of a right or warrant to purchase securities convertible into such class of Capital
Stock, having a conversion price per share, after adding thereto the exercise price, computed on the basis of the maximum number
of shares of such class of Capital Stock issuable upon conversion of such convertible securities, per share of such class of Capital
Stock, so issuable) less than the current market price per share of such class of Capital Stock (as defined in subsection (e)
below) on the date on which such issuance was declared or otherwise announced by the Issuer (the “Determination Date”),
the number of shares of such class of Capital Stock into which each $1,000 Principal amount of Securities shall be convertible
after such record date shall be determined by multiplying the number of shares of such class of Capital Stock into which such
Principal amount of Securities was convertible immediately prior to such record date by a fraction, of which the numerator shall
be the number of shares of such class of Capital Stock outstanding on the Determination Date plus the number of additional shares
of such class of Capital Stock offered for subscription or purchase (or in the case of a right or warrant to purchase securities
convertible into such class of Capital Stock, the aggregate number of additional shares of such class of Capital Stock into which
the convertible securities so offered are initially convertible), and of which the denominator shall be the number of shares of
such class of Capital Stock outstanding on the Determination Date plus the number of shares of such class of Capital Stock obtained
by dividing the aggregate offering price of the total number of shares so offered (or, in the case of a right or warrant to purchase
securities convertible into such class of Capital Stock, the aggregate initial conversion price of the convertible securities
so offered, after adding thereto the aggregate exercise price of such rights or warrants computed on the basis of the maximum
number of shares of such class of Capital Stock issuable upon conversion of such convertible securities) by such current market
price. Shares of such class of Capital Stock of the Issuer owned by or held for the account of the Issuer shall not be deemed
outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is
fixed; and to the extent that shares of such class of Capital Stock are not delivered (or securities convertible into shares of
such class of Capital Stock are not delivered) after the expiration of such rights or warrants (or, in the case of rights or warrants
to purchase securities convertible into such class of Capital Stock once exercised, the expiration of the conversion right of
such securities) the conversion rate shall be readjusted to the conversion rate which would then be in effect had the adjustments
made upon the issuance of such rights or warrants (or securities convertible into shares) been made upon the basis of delivery
of only the number of shares actually delivered. In the event that such rights or warrants are not so issued, the conversion rate
shall again be adjusted to be the conversion rate which would then be in effect if such record date had not been fixed.


 




    	- 52 -



    	 



    

 


(c)
In case the Issuer shall fix a record date for the making of a distribution to all holders of the class of Capital Stock into
which Securities of such series are convertible (including any such distribution made in connection with a consolidation or merger
in which the Issuer is the continuing corporation) of evidences of its indebtedness or assets (excluding any cash dividends paid
from retained earnings and dividends payable in Capital Stock for which adjustment is made pursuant to subsection (a) above or
(d) below) or subscription rights or warrants (excluding subscription rights or warrants to purchase the class of Capital Stock
into which Securities of such series are convertible), the number of shares of such class of Capital Stock into which each $1,000
Principal amount of Securities of such series shall be convertible after such record date shall be determined by multiplying the
number of shares of such class of Capital Stock into which such Principal amount of Securities was convertible immediately prior
to such record date by a fraction, of which the numerator shall be the fair market value of the assets of the Issuer, after deducting
therefrom all liabilities of the Issuer and all preferences (including accrued but unpaid dividends) in respect of classes of
Capital Stock having a preference with respect to the assets of the Issuer over such class of Capital Stock (all as determined
by the Board of Directors, whose determination shall be conclusive, and described in a certificate signed by chairman of the Issuer’s
Board of Directors, its president, any vice president, its treasurer, any assistant treasurer, its secretary or any assistant
secretary, filed with the Trustee and each conversion agent) on such record date, and of which the denominator shall be such fair
market value after deducting therefrom such liabilities and preferences, less the fair market value (as determined by the Board
of Directors, whose determination shall be conclusive, and described in a statement filed with the Trustee and each conversion
agent) of the assets or evidences of indebtedness, so distributed or of such subscription rights or warrants applicable, so distributed.
Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such distribution is not
so made, the conversion rate shall again be adjusted to the conversion rate which would then be in effect if such record date
had not been fixed.


 


(d)
In case the Issuer shall, by dividend or otherwise, distribute to all holders of its Capital Stock cash (excluding any dividend
or distribution in connection with the liquidation, dissolution or winding up of the Issuer, whether voluntary or involuntary),
then, in such case, unless the Issuer elects to reserve such cash for distribution to the Holders of the Securities upon the conversion
of the Securities so that any such Holder converting Securities will receive upon such conversion, in addition to the shares of
Capital Stock to which such Holder is entitled, the amount of cash which such Holder would have received if such Holder had, immediately
prior to the record date for such distribution of cash, converted its Securities into Capital Stock, the conversion rate shall
be adjusted so that the same shall equal the rate determined by multiplying the conversion rate in effect immediately prior to
the record date by a fraction of which the denominator shall be the current market price of the Capital Stock (determined as provided
in Section 12.05(e) on the record date less the amount of cash so distributed (and not excluded as provided above) applicable
to one share of Capital Stock and the numerator shall be such current market price of the Capital Stock (determined as provided
in Section 12.05(e)), such adjustment to be effective immediately prior to the opening of business on the day following the record
date; provided, however, that in the event the portion of the cash so distributed applicable to one share of Capital Stock is
equal to or greater than the current market price of the Capital Stock (determined as provided in Section 12.05(e)) on the record
date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Securityholder shall have the right to
receive upon conversion the amount of cash such Holder would have received had such Holder converted each Security on the record
date. If such dividend or distribution is not so paid or made, the conversion rate shall again be adjusted to be the conversion
rate which would then be in effect if such dividend or distribution had not been declared.


 




    	- 53 -



    	 



    

 


(e)
For the purpose of any computation under subsections (b) and (d) above and Section 12.06, the current market price per share of
the Capital Stock on any date as of which such price is to be computed shall mean the average of the Closing Prices for the 30
consecutive Business Days commencing 45 Business Days before such date.


 


(f)
No adjustment in the conversion rate shall be required unless such adjustment would require a cumulative increase or decrease
of at least 1% in such rate; provided, however, that any adjustments which by reason of this subsection (f) are
not required to be made shall be carried forward and taken into account in any subsequent adjustment; and provided further,
that adjustments shall be required and made in accordance with the provisions of this Article 12 (other than this subsection (f))
not later than such time as may be required in order to preserve the tax-free nature of a States income tax purposes to the Holders
of Securities or the class of Capital Stock into which such Securities are convertible. All calculations under this Article 12
shall be made to the nearest cent or to the nearest one-thousandth of a share, as the case may be. Anything in this Section 12.05
to the contrary notwithstanding, the Issuer shall be entitled to make such adjustments in the conversion rate, in addition to
those required by this Section 12.05, as it in its discretion shall determine to be advisable in order that any stock dividend,
subdivision of shares, distribution of rights to purchase stock or securities, or distribution of securities convertible into
or exchangeable for stock hereafter made by the Issuer to its shareholders shall not be taxable for United States income tax purposes.


 


(g)
Whenever the conversion rate is adjusted, as herein provided, the Issuer shall promptly file with the Trustee and with the office
or agency maintained by the Issuer for the conversion of Securities of such series pursuant to Section 3.02, a certificate of
a firm of independent public accountants of recognized national standing selected by the Board of Directors (who may be the regular
accountants employed by the Issuer) setting forth the conversion rate after such adjustment and setting forth a brief statement
of the facts requiring such adjustment and a computation thereof. Such certificate shall be conclusive evidence of the correctness
of such adjustment. Neither the Trustee nor any conversion agent shall be under any duty or responsibility with respect to any
such certificate or any facts or computations set forth therein, except to exhibit said certificate from time to time to any Securityholder
of such series desiring to inspect the same. The Issuer shall promptly cause a notice setting forth the adjusted conversion rate
to be mailed to the Holders of Securities of such series, as their names and addresses appear upon the register of the Issuer.


 




    	- 54 -



    	 



    

 


(h)
In the event that at any time, as a result of shares of any other class of Capital Stock becoming issuable in exchange or substitution
for or in lieu of shares of the class of Capital Stock into which such Securities are convertible or as a result of an adjustment
made pursuant to subsection (a) above, the Holder of any Security of such series thereafter surrendered for conversion shall become
entitled to receive any shares of the Issuer other than shares of the class of Capital Stock into which the Issuer of such series
are convertible, thereafter the number of such other shares so receivable upon conversion of any Security shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the
class of Capital Stock into which the Securities of such series are convertible contained in subsections (a) to (f), inclusive,
above, and the provisions of this Article 12 with respect to the class of Capital Stock into which the Securities of such series
are convertible shall apply on like terms to any such other shares.


 


(i)
The conversion rate with respect to any Original Issue Discount Security, the terms of which provide for convertibility, shall
not be adjusted during the term of such Original Issue Discount Security for accrued original issue discount.


 


(j)
In the event that the Securities of any series are convertible into more than one class of Capital Stock, the provisions of this
Section 12.05 shall apply separately to events affecting each such class.


 


Section
12.06 No Fractional Shares to Be Issued. No fractional shares of Capital Stock shall be issued upon conversions of Securities.
If more than one Security of any series shall be surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate Principal amount of the
Securities of such series (or specified portions thereof to the extent permitted hereby) so surrendered. Instead of a fraction
of a share of Capital Stock which would otherwise be issuable upon conversion of any Security or Securities (or specified portions
thereof), the Issuer shall pay a cash adjustment in respect of such fraction of a share in an amount equal to the same fractional
interest of the current market price (as defined in Section 12.05) per share of Capital Stock on the Business Day next preceding
the day of conversion.


 


Section
12.07 Preservation of Conversion Rights Upon Consolidation, Merger, Sale or Conveyance. In case of any consolidation of
the Issuer with, or merger of the Issuer into, any other corporation (other than a consolidation or merger in which the Issuer
is the continuing corporation), or in the case of any sale or transfer of all or substantially all of the assets of the Issuer,
the corporation formed by such consolidation or the corporation into which the Issuer shall have been merged or the corporation
which shall have acquired such assets, as the case may be, shall execute and deliver to the Trustee, a supplemental indenture,
subject to the provisions of Article 7 and 8 as they relate to supplemental indentures, providing that the Holder of each Security
then Outstanding of a series which was convertible into Capital Stock shall have the right thereafter to convert such Security
into the kind and amount of shares of stock and other securities and property, including cash, receivable upon such consolidation,
merger, sale or transfer by a holder of the number of shares of Capital Stock of the Issuer into which such Securities might have
been converted immediately prior to such consolidation, merger, sale or transfer. Such supplemental indenture shall conform to
the provisions of the Trust Indenture Act of 1939 as then in effect and shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article 12. Neither the Trustee nor any conversion agent
shall be under any responsibility to determine the correctness of any provision contained in any such supplemental indenture relating
either to the kind or amount of shares of stock or other securities or property receivable by Securityholders upon the conversion
of their Securities after any such consolidation, merger, sale or transfer, or to any adjustment to be made with respect there
to and, subject to the provisions of Article 5, may accept as conclusive evidence of the correctness of any such provisions, and
shall be protected in relying upon, an Opinion of Counsel with respect thereto. If in the case of any such consolidation, merger,
sale or transfer, the stock or other securities and property receivable by a Holder of the Securities includes stock or other
securities and property of a corporation other than the successor or purchasing corporation, then such supplemental indenture
shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the
Holders of the Securities as the Board of Directors shall reasonably consider necessary. The above provisions of this Section
12.07 shall similarly apply to successive consolidations, mergers, sales or transfers.

issuance and delivery of any such certificate in a name other than that of the Holder of the Security converted, and the Issuer
shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof
shall have paid to the Issuer the amount of such tax or shall have established to the satisfaction of the Issuer that such tax
has been paid.

time be under any duty or responsibility to any Securityholder to determine whether any facts exist which may require any adjustment
of the conversion rate or conversion price, or with respect to the nature or extent of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither
the Trustee nor any conversion agent shall be accountable with respect to the registration under securities laws, listing, validity
or value (or the kind or amount) of any shares of Capital Stock, or of any other securities or property, which may at any time
be issued or delivered upon the conversion of any Security; and neither the Trustee nor any conversion agent makes any representation

Senior Note Due ●


 


1.
Interest.


 


CORBUS
PHARMACEUTICALS HOLDINGS, INC., a Delaware corporation (the “Issuer”), promises to pay interest on the Principal amount
of this Security at the rate per annum shown above. Cash interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from ●. The Issuer will pay interest semi-annually in arrears on
each Interest Payment Date, commencing ●. Interest will be computed on the basis of a 360-day year of twelve 30-day months.


 


The
Issuer shall pay interest on overdue Principal from time to time on demand at the rate borne by the Securities and on overdue
installments of interest (without regard to any applicable grace periods) to the extent lawful.


 


2.
Method of Payment.


 


The
Issuer shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close
of business on the Interest Record Date immediately preceding the Interest Payment Date notwithstanding any transfer or exchange
of such Security subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must surrender Securities
to the Trustee to collect Principal payments. The Issuer shall pay Principal and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). However,
the payments of interest, and any portion of the Principal (other than interest payable at maturity or on any redemption or repayment
date or the final payment of Principal) shall be made by the Paying Agent, upon receipt from the Issuer of immediately available
funds by 11:00 a.m., New York City time (or such other time as may be agreed to between the Issuer and the Paying Agent or the
Issuer), directly to a Holder (by Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to
the Trustee 15 days prior to such payment date requesting that such payment will be so made and designating the bank account to
which such payments shall be so made and in the case of payments of Principal surrenders the same to the Trustee in exchange for
a Security or Securities aggregating the same principal amount as the unredeemed Principal amount of the Securities surrendered.


 


3.
Paying Agent.


 


Initially,
● (the “Trustee”) will act as Paying Agent. The Issuer may change any Paying Agent without notice to
the Holders.


 




    	- 1 -



    	 



    

 


4.
Indenture.


 


The
Issuer issued the Securities under an Indenture, dated as of ● (the “Indenture”), between the Issuer
and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the
Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act
of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture until such
time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the Indenture is qualified
under the TIA. Notwithstanding anything to the contrary herein, the Securities are subject to all such terms, and Holders of Securities
are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Security
are inconsistent, the terms of the Indenture shall govern.


 


5.
Denominations; Transfer; Exchange.


 


The
Securities are in registered form, without coupons, in denominations of $1,000 and multiples of $1,000. A Holder shall register
the transfer of or exchange Securities in accordance with the Indenture. The Issuer may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable
in connection therewith as permitted by the Indenture. The Issuer need not issue, authenticate, register the transfer of or exchange
any Securities or portions thereof for a period of fifteen (15) days before such series is selected for redemption, nor need the
Issuer register the transfer or exchange of any security selected for redemption in whole or in part.


 


6.
Persons Deemed Owners.


 


The
registered Holder of a Security shall be treated as the owner of it for all purposes.


 


7.
Unclaimed Funds.


 


If
funds for the payment of Principal or interest remain unclaimed for two years, the Trustee and the Paying Agent will repay the
funds to the Issuer at its written request. After that, all liability of the Trustee and such Paying Agent with respect to such
funds shall cease.


 


8.
Legal Defeasance and Covenant Defeasance.


 


The
Issuer may be discharged from its obligations under the Securities and under the Indenture with respect to the Securities except
for certain provisions thereof, and may be discharged from obligations to comply with certain covenants contained in the Securities
and in the Indenture with respect to the Securities, in each case upon satisfaction of certain conditions specified in the Indenture.


 


9.
Amendment; Supplement; Waiver.


 


Subject
to certain exceptions, the Securities and the provisions of the Indenture relating to the Securities may be amended or supplemented
with the written consent of the Holders of at least a majority in aggregate Principal amount of the Securities then outstanding,
and any existing Default or Event of Default or compliance with certain provisions may be waived with the consent of the Holders
of a majority in aggregate Principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the
parties thereto may amend or supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or
inconsistency, provide for uncertificated Securities in addition to or in place of certificated Securities or comply with any
requirements of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act, or make any
other change that does not adversely affect the rights of any Holder of a Security.

10.
Defaults and Remedies.


 


If
an Event of Default (other than certain bankruptcy Events of Default with respect to the Issuer) occurs and is continuing, the
Trustee or the Holders of at least 25% in aggregate Principal amount of Securities then outstanding may declare all of the Securities
to be due and payable immediately in the manner and with the effect provided in the Indenture. If a bankruptcy Event of Default
with respect to the Issuer occurs and is continuing, all the Securities shall be immediately due and payable immediately in the
manner and with the effect provided in the Indenture without any notice or other action on the part of the Trustee or any Holder.
Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee is not
obligated to enforce the Indenture or the Securities unless it has received indemnity satisfactory to it. The Indenture permits,
subject to certain limitations therein provided, Holders of a majority in aggregate Principal amount of the Securities then outstanding
to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Securities notice of certain
continuing Defaults or Events of Default if it determines that withholding notice is in their interest.


 


11.
Conversion.


 


Reference
is made to the Indenture, including, without limitation, provisions giving the Holder of this Security the right to convert this
Security into Capital Stock of the Issuer on the terms and subject to the limitations as more fully specified in the Indenture.
The initial conversion rate for this Security is ●. This conversion rate is subject to modification as provided in the Indenture.
Such further provisions shall for all purposes have the same effect as though fully set forth at this place.


 


12.
Trustee Dealings with Issuer.


 


The
Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Issuer as if it were not the Trustee.


 


13.
No Recourse Against Others.


 


No
stockholder, director, officer, employee or incorporator, as such, of the Issuer or any successor Person thereof shall have any
liability for any obligation under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of a Security by accepting a Security waives and releases all such liability. The waiver
and release are part of the consideration for the issuance of the Securities.

14.
Authentication.


 


This
Security shall not be valid until the Trustee manually signs the certificate of authentication on this Security.


 


15.
Abbreviations and Defined Terms.


 


Customary
abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian),
and U/G/M/A (= Uniform Gifts to Minors Act).


 


16.

Pursuant
to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy
of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.
