A. Prior

Company and the Holder further desire to exchange (collectively, the “Exchange”) the Existing Warrant, in full,
into such aggregate number of Common Stock as set forth on the signature page of the Holder attached hereto (the “Exchange
Stock”), which represents an Exchange ratio of 1 Existing Warrant Stock :0.6 Common Stock.

 

C.
 The Exchange is being made in reliance upon the exemption from registration provided

that they have been restated/amended and filed with SEC. Such financial statements have been prepared in accordance with generally

be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements,
to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects
the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods
then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either
individually or in the aggregate). No other information provided by or on behalf of the Company to the Holder which is not included
in the SEC Documents (including, without limitation, information in the disclosure schedules to this Agreement) contains any untrue
statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light
of the circumstance under which they are or were made, not misleading. The Company is not currently contemplating to amend or
restate any of the financial statements (including, without limitation, any notes or any letter of the independent accountants

that would reasonably be expected to have a Material Adverse Effect on the Company or its Subsidiaries, whether of a civil or
criminal nature or otherwise, in their capacities as such. No director, officer or employee of the Company or any of its subsidiaries
has willfully violated 18 U.S.C. §1519 or engaged in spoliation in reasonable anticipation of litigation. Without limitation

by the SEC involving the Company, any of its subsidiaries or any current or former director or officer of the Company or any of
its subsidiaries. The SEC has not issued any stop order or other order suspending the effectiveness of any registration statement
filed by the Company under the Securities Act or the 1934 Act. Neither the Company nor any of its subsidiaries is subject to any

of the Issuer, pursuant to the terms of such Securities or securities or of any agreement entered into by the Issuer, the ratio
of the principal amount of the Securities of the series to be issued to the principal amount of the Securities or securities to
be surrendered in exchange, and any other material terms of the exchange; and

 

(u)
any other terms of the series.

 

The
Issuer may from time to time, without notice to or the consent of the holders of any series of Securities, create and issue further
Securities of any such series ranking equally with the Securities of such series in all respects (or in all respects other than
(1) the payment of interest accruing prior to the issue date of such further Securities or (2) the first payment of interest following
the issue date of such further Securities). Such further Securities may be consolidated and form a single series with the Securities
of such series and have the same terms as to status, redemption or otherwise as the Securities of such series.

 

Section
2.04 Authentication and Delivery of Securities. The Issuer may deliver Securities of any series executed by the Issuer
to the Trustee for authentication together with the applicable documents referred to below in this Section, and the Trustee shall
thereupon authenticate and deliver such Securities to or upon the order of the Issuer (contained in the Issuer Order referred
to below in this Section) or pursuant to such procedures acceptable to the Trustee and to such recipients as may be specified
from time to time by an Issuer Order. The maturity date, original issue date, interest rate and any other terms of the Securities
of such series shall be determined by or pursuant to such Issuer Order and procedures. If provided for in such procedures, such
Issuer Order may authorize authentication and delivery pursuant to oral instructions from the Issuer or its duly authorized agent,
which instructions shall be promptly confirmed in writing. In authenticating such Securities and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall
be fully protected in relying upon: 

 

    	 	6	 

    	 

    

 

(a)
an Issuer Order requesting such authentication and setting forth delivery instructions if the Securities are not to be delivered
to the Issuer;

 

(b)
any Board Resolution, Officer’s Certificate and/or executed supplemental indenture referred to in Sections 2.01 and 2.03
by or pursuant to which the forms and terms of the Securities were established;

 

(c)
an Officer’s Certificate setting forth the form or forms and terms of the Securities stating that the form or forms and
terms of the Securities have been established pursuant to Sections 2.01 and 2.03 and comply with this Indenture, and covering
such other matters as the Trustee may reasonably request; and

 

(d)
an Opinion of Counsel to the effect that:

 

(i)
the form or forms and terms of such Securities have been established pursuant to Sections 2.01 and 2.03 and comply with this Indenture,

 

(ii)
the authentication and delivery of such Securities by the Trustee are authorized under the provisions of this Indenture,

 

(iii)
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, and

 

(iv)
all laws and requirements in respect of the execution and delivery by the Issuer of the Securities have been complied with, and
covering such other matters as the Trustee may reasonably request.

 

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 to existing Holders or would affect the Trustee’s
own rights, duties or immunities under the Securities, this Indenture or otherwise.

 

The
Issuer shall execute and the Trustee shall, in accordance with this Section with respect to the Securities of a series, authenticate
and deliver one or more 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 and not yet cancelled, (ii) shall be registered in the name of
the Depositary for such Global Security or Securities or the nominee of such Depositary, (iii) shall be delivered by the Trustee
to such Depositary 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 the 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.”

 

Each
Depositary designated pursuant to this Section must, at the time of its designation and at all times while it serves as Depositary,
be a clearing agency registered under the Securities Exchange Act of 1934 and any other applicable statute or regulation.

 

Section
2.05 Execution of Securities. The Securities shall be signed on behalf of the Issuer by the chairman of its Board of Directors,
any vice chairman of its Board of Directors, its chief executive officer, its principal financial officer, its president, any
vice president or its treasurer. Such signatures may be the manual or facsimile signatures of the present or any future such officers.
Typographical and other minor errors or defects in any such reproduction of any such signature shall not affect the validity or
enforceability of any Security that has been duly authenticated and delivered by the Trustee. 

 

    	 	7	 

    	 

    

 

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.

 

Section
2.06 Certificate of Authentication. Only such Securities as shall bear thereon a certificate of authentication substantially
in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be
entitled to the benefits of this Indenture or be valid or obligatory for any purpose. The execution of such certificate by the
Trustee upon 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 of each series shall be issuable in denominations
established as contemplated by Section 2.03 or, if not so established, in denominations of $1,000 and any integral multiple thereof.
The Securities of each series 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 with the approval of the Trustee, as evidenced by the execution
and authentication thereof. Unless otherwise indicated in a Board Resolution, Officer’s Certificate or supplemental indenture
for a particular series, interest will be calculated on the basis of a 360-day year of twelve 30-day months. 

 

Each
Security shall be dated the date of its authentication. The Securities of each series shall bear interest, if any, from the date,
and such interest shall be payable on the dates, established 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, exchange or conversion 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) for the Securities
of any series shall mean the date specified as such in the terms of the Securities of such series established as contemplated
by Section 2.03, or, if no such date is so established, if such interest payment date is the first day of a calendar month, the
15th day of the immediately preceding calendar month or, if such interest payment date is the 15th 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 at each office or agency to be maintained for the purpose
as provided in Section 3.02 for each series of Securities a register or registers in which, subject to such reasonable regulations
as it may prescribe, it will provide for the registration of Securities of such series and the registration of transfer of Securities
of such series. 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. 

 

Upon
due presentation for registration of transfer of any Security of any series at any such office or agency to be maintained for
the purpose as provided in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of
the transferee or transferees a new Security or Securities of the same series, maturity date, interest rate and original issue
date in authorized denominations for a like aggregate principal amount.

 

    	 	8	 

    	 

    

 

At
the option of the Holder thereof, Securities of any series (except a Global Security) may be exchanged for a Security or Securities
of such series having authorized denominations and an equal aggregate principal amount, upon surrender of such 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. Whenever any Securities are so surrendered for exchange,
the Issuer shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange
is entitled to receive. All Securities surrendered upon any exchange or transfer provided for in this Indenture shall be promptly
cancelled and disposed of by the Trustee and the Trustee will deliver a certificate of disposition thereof to the Issuer.

 

All
Securities presented for registration of transfer, exchange, redemption or payment shall (if so required by the Issuer or the
Trustee) 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 or her attorney duly authorized in writing.

 

The
Issuer may require payment of a sum sufficient to cover any stamp or other 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.

 

The
Issuer shall not be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days immediately
preceding the first mailing of notice of redemption of Securities of such series to be redeemed or (b) any Securities selected,
called or being called for redemption, in whole or in part, except, in the case of any Security to be redeemed in part, the portion
thereof not so to be redeemed.

 

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 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 the Securities of a series notifies the Issuer that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the Securities of a series shall no longer be eligible
under Section 2.04, the Issuer shall appoint a successor Depositary with respect to the Securities of such series. If a successor
Depositary for the Securities of such series is not appointed by the Issuer within 90 days after the Issuer receives such notice
or becomes aware of such ineligibility, the Issuer’s determination pursuant to Section 2.03 that the Securities of such
series be represented by a Global Security shall no longer be effective and the Issuer will execute, and the Trustee, upon receipt
of an Officer’s Certificate for the authentication and delivery of definitive Securities of such series, will authenticate
and deliver, Securities of such series in definitive registered form, in any authorized denominations, in an aggregate principal
amount equal to the principal amount of the Global Security or Securities representing the Securities of such series, in exchange
for such Global Security or Securities.

 

The
Issuer may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more
Global Securities shall no longer be represented by a Global Security or Securities. In such event the Issuer will execute, and
the Trustee, upon receipt of an Officer’s Certificate for the authentication and delivery of definitive Securities of such
series, will authenticate and deliver, Securities of such series in definitive registered form, in any authorized denominations,
in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series,
in exchange for such Global Security or Securities.

 

The
Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for Securities of the same
series in definitive registered form in accordance with the two preceding paragraphs or on such other terms as are acceptable
to the Issuer and such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver, without
service charge,

 

(i)
to the Person specified by such Depositary a new Security or Securities of the same series, 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 Global Security; and

 

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

 

    	 	9	 

    	 

    

 

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

 

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.

 

Section
2.09 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall become
mutilated, defaced or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request of
any officer of the Issuer, the Trustee shall authenticate and deliver a new Security of the same series, maturity date, interest
rate and original issue date, bearing a number or other distinguishing symbol not contemporaneously outstanding, in exchange and
substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so destroyed, lost or stolen.
In every case the applicant for a substitute Security shall furnish 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, in every case of destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of such Security
and of the ownership thereof and in the case of mutilation or defacement shall surrender the Security to the Trustee. 

 

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) connected
therewith. In case any Security which has matured or is about to mature or has been called for redemption in full, or is being
surrendered for conversion in full, shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer may, instead
of issuing a substitute Security (with the Holder’s consent, in the case of convertible Securities), pay or authorize the
payment of the same or convert, or authorize conversion 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 indemnity as any of them may require to save each of them harmless, and, in every case of destruction,
loss or theft, 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 theft of such Security and of the ownership thereof.

 

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 stolen 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 or conversion
of mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments
or other securities without their surrender.

 

Section
2.10 Cancellation of Securities; Destruction Thereof. All Securities surrendered for exchange for Securities of the same
series or for payment, redemption, registration of transfer, conversion or for credit against any payment in respect of a sinking
or analogous fund, 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 cancelled 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 cancelled Securities held by it
and deliver a certificate of disposition to the Issuer. If the Issuer shall acquire any of the Securities, such acquisition shall
not operate as a redemption or satisfaction of the Debt represented by such Securities unless and until the same are delivered
to the Trustee for cancellation. 

 

    	 	10	 

    	 

    

 

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 in 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 as evidenced by the execution and authentication thereof. 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 an equal aggregate principal amount of definitive Securities of the same series having authorized denominations.
Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under this Indenture as definitive
Securities of such series, unless the benefits of the temporary Securities are limited pursuant to Section 2.03.

agent a sum sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer

assignee, custodian, trustee or sequestrator (or similar official) of the Issuer or for all or substantially all of its property
and assets or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect
for a period of 90 consecutive days; or

 

    	 	13	 

    	 

    

 

(e)
the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment
of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Issuer
or for any substantial part of its property and assets, or make any general assignment for the benefit of creditors; or

 

(f)
any other Event of Default provided for in such series of Securities.

 

If
an Event of Default described in clauses (a), (b), (c) or (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 such series then Outstanding hereunder (each
such series voting as a separate class) by notice in writing to the Issuer (and also 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 (d) or (e) occurs and is continuing, then and in each and every such case, the entire
principal (or, if any Securities are Original Issue Discount Securities, such portion of the principal as may be specified in
the terms thereof) of all the Securities then Outstanding and interest accrued thereon, if any, shall become immediately due and
payable.

 

The
foregoing provisions, however, are subject to the condition that if, at any time after the principal of the Securities of any
series shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall
have been obtained or entered as hereinafter provided, the 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 and the principal of any and all Securities
of such series 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 specified in the Securities of such series 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 with respect to such series, other than the non-payment of the principal of Securities of such series which
shall have become due solely by such 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 Securities of such series then Outstanding,
by written notice to the Issuer and to the Trustee, may waive all defaults with respect to such series 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.

 

Unless
otherwise indicated in the Board Resolution, Officer’s Certificate or supplemental indenture for a series of Original Issue
Discount Securities, 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
5.02 Collection of Debt by Trustee; Trustee May Prove Debt. The Issuer covenants that (a) 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 (b) 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, upon demand of
the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series 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, 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, attorneys and counsel, and any expenses and liabilities incurred, and all
advances made, by the Trustee and each predecessor trustee except as a result of its negligence or bad faith. 

 

    	 	14	 

    	 

    

 

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

 

In
case there shall be pending proceedings relative to the Issuer or any other obligor upon the Securities under Title 11 of the
United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for
or taken possession of the Issuer or its property or such other obligor or its property, or in case of any other comparable judicial
proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or property of the
Issuer or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant
to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise:

 

(i)
to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are Original
Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid
in respect of the Securities of any series, and to file such other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for 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
in any judicial proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or
property of the Issuer or such other obligor,

 

(ii)
unless prohibited by applicable law and regulations, to vote on behalf of the Holders of the Securities of any series in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or
person performing similar functions in comparable proceedings, and

 

(iii)
to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received
with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver or liquidator,
custodian or other similar official is hereby authorized by each of the Securityholders to make payments to the Trustee, and,
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 6.06.

 

Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf
of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Securities of any series
or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any
such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person.

 

All
rights of action and of asserting claims under this Indenture, or under any of the Securities of any series, may be enforced by
the Trustee without the possession of any of the Securities of such series 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.

 

    	 	15	 

    	 

    

 

In
any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture
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
5.03 Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article in respect of any series shall
be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on
account of principal or interest, upon presentation of the several Securities in respect of which monies have been collected and
stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange
for the presented Securities of like series if only partially paid, or upon surrender thereof if fully paid: 

 

FIRST:
To the payment of all amounts due to the Trustee or any predecessor trustee pursuant to Section 6.06;

 

SECOND:
In case the principal of the Securities of such series in respect of which moneys have been collected shall not have become and
be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of
the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest, to the extent permitted by applicable law, at the same rate as the rate of interest or Yield
to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be made ratably
to the Persons entitled thereto, without discrimination or preference;

 

THIRD:
In case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall
be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal
and interest, with interest upon the overdue principal, and (to the extent that such interest has been collected by the Trustee)
upon overdue installments of interest, to the extent permitted by applicable law, 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 in case
such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to
the payment of such principal and interest, without preference or priority of principal over interest, or of interest over principal,
or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security
of such series, ratably to the aggregate of such principal and accrued and unpaid interest; and

 

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

 

Section
5.04 Suits for Enforcement. In case an Event of Default has occurred, has not been waived and is continuing, the Trustee
may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any such rights, either at law or in equity or in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture
or by law. 

 

Section
5.05 Restoration of Rights on Abandonment of Proceedings. In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee, then and in every such case (subject to any determination in such proceeding) the Issuer and the Trustee
shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer,
the Trustee and the Securityholders shall continue as though no such proceedings had been taken.

 

    	 	16	 

    	 

    

 

Section
5.06 Limitations on Suits by Securityholders. 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 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 its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity
as it may require against the costs, expenses and liabilities to be incurred therein or thereby 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 5.09; 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 of the applicable series. For the protection
and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief
as can be given either at law or in equity. 

 

Section
5.07 Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding any other provision in this Indenture
and any provision of any Security, the right of any Holder of any Security to receive payment of the principal of and interest
on such Security on or after the respective due dates expressed in such Security in accordance with the terms hereof and thereof,
or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder; 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
of the applicable series. For the protection and enforcement of the provisions of this Section, each and every Securityholder
and the Trustee shall be entitled to such relief as can be given either at law or in equity.

 

Section
5.08 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided in Section 5.06, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities 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 Holder of Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event
of Default or an acquiescence therein; and, subject to Section 5.06, every power and remedy given by this Indenture or by law
to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as shall be deemed expedient,
by the Trustee or by the Holders of Securities.

 

Section
5.09 Control by Holders of Securities. 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 6.01) 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 involve the Trustee in 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, it being understood that (subject
to Section 6.01) the Trustee shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial
to such Holders. 

 

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

 

    	 	17	 

    	 

    

 

Section
5.10 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities of such series
at the time Outstanding, by notice to the Trustee, may on behalf of the Holders of all the Securities of such series waive any
existing default in the performance of any of the covenants contained herein or established pursuant to Section 2.03 with respect
to such series and its consequences, except an uncured default in the payment of the principal of, or interest on, any of the
Securities of that series as and when the same shall become due by the terms of such Securities; and may rescind an acceleration
and its consequences, including any related payment default that resulted from such acceleration. In the case of any such waiver,
the Issuer, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights
hereunder, respectively, 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
5.11 Trustee to Give Notice of Default. The Trustee shall, within 90 days after the occurrence of a default with respect
to the Securities of any series, give notice of all defaults with respect to that series known to the Trustee to all Holders of
Securities of such series in the manner and to the extent provided in Section 4.03, unless in each case such defaults shall have
been cured before the mailing or publication of such notice (the term “defaults” for the purpose 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, or in the payment of any sinking fund installment on 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
5.12 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 or her acceptance thereof shall be deemed to have agreed, that any court may in its discretion require,
in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the Trustee, to 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 to any suit instituted by any Securityholder for the enforcement of the payment of the principal of or interest
on any Security of such series, on or after the respective due dates expressed in such Security or established pursuant to this
Indenture. 

 

ARTICLE
6

CONCERNING
THE TRUSTEE

 

Section
6.01 Duties and Responsibilities of the Trustee; During Default; Prior to Default. 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 his or her own affairs. 

 

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.

 

Section
6.02 Certain Rights of the Trustee. In furtherance of and subject to the Trust Indenture Act of 1939 and subject to Section
6.01: 

 

    	 	18	 

    	 

    

 

(a)
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)
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;

 

(c)
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
the direction of the Holders pursuant to Section 5.09 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;

 

(d)
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;

 

(e)
the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officer’s Certificate
or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, 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;

 

(f)
any request, direction, order or demand of the Issuer mentioned herein shall be sufficiently evidenced by an Officer’s 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;

 

(g)
the Trustee may consult with counsel 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;

 

(h)
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
therein or thereby;

 

(i)
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;

 

(j)
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, 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 reasonable
indemnity against such expenses or liabilities as a condition to proceeding; 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;
and 

 

(k)
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.

Section
6.03 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 of 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. 

 

Section
6.04 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
6.05 Moneys Held by Trustee. Subject to the provisions of Section 10.04 hereof, all moneys received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated
from other funds except to the extent required by 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 moneys received by it hereunder. 

 

Section
6.06 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 reasonable compensation (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) as the Issuer and the Trustee may from time to time agree
in writing and, except as otherwise expressly provided herein, 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 any such expense, disbursement
or advance as may arise from its negligence or bad faith. The Issuer also covenants to indemnify the Trustee and each predecessor
trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties
hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in the premises.
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. Such additional indebtedness shall be a senior claim
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. 

 

Section
6.07 Right of Trustee to Rely on Officer’s Certificate, Etc. Subject to Sections 6.01 and 6.02, 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 Officer’s Certificate delivered to the Trustee, and such certificate, in the absence of negligence or
bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under
the provisions of this Indenture upon the faith thereof. 

 

Section
6.08 Disqualification; Conflicting Interests. If the Trustee has or shall acquire any “conflicting interest”

be a corporation having a combined capital and surplus of at least $50,000,000 and shall be eligible in accordance with the provisions
of Section 310(a) of the Trust Indenture Act of 1939. If such corporation 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 shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.

Section
6.10 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 and by mailing notice of such resignation to the Holders of then Outstanding Securities of each series affected at their
addresses as they shall appear on the Security register. 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 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, on behalf of himself or herself 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; or

 

(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

 

(iii)
the Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged 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, (A) 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, one copy of which instrument
shall be delivered to the Trustee so removed and one copy to the successor trustee, or, (B) 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 or herself 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, with the consent of the Issuer, 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 for in Section 7.01 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 6.10 shall become effective upon acceptance of appointment by the
successor trustee as provided in Section 6.11.

 

Section
6.11 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 6.10 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;
but, nevertheless, 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 10.04, pay over to the successor trustee all moneys 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 6.06.

 

    	 	21	 

    	 

    

 

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.

 

No
successor trustee with respect to any series of Securities shall accept appointment as provided in this Section 6.11 unless at
the time of such acceptance such successor trustee shall be qualified under the provisions of Section 310(b) of the Trust Indenture
Act of 1939 and eligible under the provisions of Section 310(a) of the Trust Indenture Act of 1939.

 

Upon
acceptance of appointment by any successor trustee as provided in this Section 6.11, the Issuer shall mail notice thereof to the
Holders of Securities of each series affected, by mailing such notice to such Holders at their addresses as they shall appear
on 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 6.10. If the Issuer fails to mail such
notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice
to be given at the expense of the Issuer.

 

Section
6.12 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 the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder; provided, that such corporation shall be qualified under the provisions of Section
310(b) of the Trust Indenture Act of 1939 and eligible under the provisions of Section 310(a) of the Trust Indenture Act of 1939,
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
6.13 Preferential Collection of Claims Against the Issuer. The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or
been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

CONCERNING
THE SECURITYHOLDERS

 

Section
7.01 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 Sections 6.01 and 6.02) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Article. 

 

    	 	22	 

    	 

    

 

Section
7.02 Proof of Execution of Instruments and of Holding of Securities. Subject to Sections 6.01 and 6.02, the execution of
any instrument by a Holder or his agent or proxy may be proved in accordance with such reasonable rules and regulations as may
be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. 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 any series entitled to vote or consent to any action referred to in Section 7.01, 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 such series of record on such record date shall be entitled to so
vote or give such consent or revoke such vote or consent. Notice of such record date may be given before or after any request
for any action referred to in Section 7.01 is made by the Issuer. 

 

Section
7.03 Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of the Issuer or of 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 or her order,
shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable.

 

Section
7.04 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 which the Trustee knows 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. 

 

Section
7.05 Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided
in Section 7.01, 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 serial number of which is shown by the evidence to be included among the serial numbers of the Securities the Holders of which
have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided
in this Article, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the Holder
of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of
any Securities issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or
not any notation in regard thereto is made upon any such Security. Any action taken 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 shall be conclusively binding upon the Issuer, the Trustee and the Holders of all the Securities affected by such action.

to add to the covenants of the Issuer such further covenants, restrictions, conditions or provisions as its Board of Directors

the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, that in
respect of any such additional covenant, restriction, condition or provision such supplemental indenture may provide for a particular
period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide
for an immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event
of Default or may limit the right of the Holders of a majority in aggregate principal amount of the Securities of such series
to waive such an Event of Default;

(k)
to make any other change that does not adversely affect the interests of the Holders of the Securities in any material respect.

 

The
Trustee shall join with the Issuer in the execution of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise.

 

Any
supplemental indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any
of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 8.02.

 

    	 	24	 

    	 

    

 

Section
8.02 Supplemental Indentures With Consent of Securityholders. With the consent (evidenced as provided in Article 7) of
the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of one or more
series affected by such supplemental indenture (voting as separate series), the Issuer, when authorized by a resolution of the
Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture
or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such consenting
series; provided, that no such supplemental indenture shall, without the consent of the Holder of each Security so affected,
(a) extend the final maturity of any Security, or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption thereof, or make the principal thereof (including any
amount in respect of original issue discount) or interest thereon payable in any currency other than that provided in the Securities
or in accordance with the terms thereof, or reduce the amount of the principal of an Original Issue Discount Security that would
be due and payable upon an acceleration of the maturity thereof pursuant to Section 5.01 or the amount thereof provable in bankruptcy
pursuant to Section 5.02, or (b) waive a default in the payment of principal of any Security or interest thereon or change a provision
related to the waiver of past defaults or changes or impair the right of any Securityholder to institute suit for the payment
or conversion thereof or, if the Securities provide therefor, any right of repayment at the option of the Securityholder, or (c)
modify any of the provisions of this section except to increase any required percentage or to provide that certain other provisions
cannot be modified or waived without the consent of the Holder of each Security so affected, or (d) reduce the aforesaid percentage
of Securities of any series, the consent of the Holders of which is required for any such supplemental indenture or the consent
of Holders of which is required for any modification, amendment or waiver of compliance with certain provisions of this Indenture
or certain defaults hereunder and their consequences provided for in this Indenture.

 

A
supplemental indenture which changes or eliminates any covenant, Event of Default or other provision of this Indenture (1) that
has been expressly included solely for the benefit of one or more particular series of Securities, if any, or (2) which modifies
the rights of Holders of Securities of one or more series with respect to any covenant, Event of Default or provision, shall be
deemed not to affect the rights under this Indenture of the Holders of Securities of any other series with respect to which such
covenant, Event of Default or other provision has not been included or so modified.

 

Upon
the request of the Issuer, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required
by Section 7.01, the Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee
may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

 

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

 

Promptly
after the execution by the Issuer and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall give a notice thereof to the Holders of then Outstanding Securities of each series affected thereby, by mailing
a notice thereof by first-class mail to such Holders at their addresses as they shall appear on the Security register, and in
each case such notice shall set forth in general terms the substance of such supplemental indenture. Any failure of the Trustee
to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental
indenture.

 

Section
8.03 Effect of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions hereof,
this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations
of rights, obligations, duties and immunities under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes.

Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be
prepared by the Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding.

State of incorporation or convert the Issuer’s form of organization to another form, or (ii) the merger of the Issuer with
or into a single direct or indirect wholly owned Subsidiary.

transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under
this Indenture with the same effect as if such successor Person had been named as the Issuer herein, and thereafter, except in
the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities.

(b)
The following subsection shall apply to the Securities of each series unless specifically otherwise provided in a Board Resolution,
Officer’s Certificate or indenture supplemental hereto provided pursuant to Section 2.03. In addition to the right to discharge
of the Indenture pursuant to subsection (a) above, the Issuer, at its option and at any time, by written notice by an officer
delivered to the Trustee, may elect to have all of its obligations discharged with all Outstanding Securities of a series (“Legal
Defeasance”), such discharge to be effective on the date that the conditions set forth in clauses (i) through (iv) and
(vi) of Section 10.01(d) are satisfied, and thereafter the Issuer shall be deemed to have paid and discharged the entire Debt
on all the Securities of such a series, and satisfied all its other obligations under such Securities and this Indenture insofar
as such Securities are concerned and this Indenture shall cease to be of further effect with respect to Securities of such series
(except as to (1) rights of registration of transfer, conversion and exchange of Securities of such series, (2) substitution of
apparently mutilated, defaced, destroyed, lost or stolen Securities, (3) rights of Holders of Securities to receive, solely from
the trust fund described in Section 10.01(d)(i), payments of principal thereof and interest thereon, upon the original stated

(c)
The following subsection shall apply to the Securities of each series unless specifically otherwise provided in a Board Resolution,
Officer’s Certificate or indenture supplemental hereto provided pursuant to Section 2.03. In addition to the right to discharge
of the Indenture pursuant to subsection (a) and to Legal Defeasance pursuant to subsection (b), above, the Issuer, at its option
and at any time, by written notice executed by an officer delivered to the Trustee, may elect to have its obligations under any
covenant contained in this Indenture or in the Board Resolution or supplemental indenture relating to such series pursuant to
Section 2.03 discharged with respect to all Outstanding Securities of a series, this Indenture and any indentures supplemental
to this Indenture with respect to such series (“Covenant Defeasance”), such discharge to be effective on the
date the conditions set forth in clauses (i) through (iii) and (v) through (vi) of Section 10.01(d) are satisfied, and such Securities
shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration
of Securityholders (and the consequences of any thereof) in connection with such covenants, but shall continue to be “Outstanding”
for all other purposes under this Indenture. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding
Securities of a series, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation
set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant
or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply
shall not constitute an Event of Default under Section 5.01(c) or otherwise, but except as specified in this Section 10.01(c),
the remainder of the Issuer’s obligations under the Securities of such series, this Indenture, and any indentures supplemental
to this Indenture with respect to such series shall be unaffected thereby.

Outstanding Securities of such series to maturity or redemption, as the case may be, and to pay all other amounts payable by it
hereunder, provided that (A) the trustee of the irrevocable trust, if any, shall have been irrevocably instructed to pay such
funds or the proceeds of such U.S. Government Obligations to the Trustee and (B) the Trustee shall have been irrevocably instructed

or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize
gain or loss for Federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect
to such Securities and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as
would be the case if such deposit, defeasance and discharge were not to occur;

 

(v)
in the event of an election for Covenant Defeasance under subsection (c), the Issuer shall have delivered to the Trustee an Opinion
of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as
a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal
income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance
were not to occur; and

become due thereon for principal and interest; but such money need not be segregated from other funds except to the extent required
by law.

 

Section
10.03 Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture with
respect to Securities of any series, all moneys then held by any paying agent under the provisions of this Indenture with respect
to such series of Securities shall, upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

 

Section
10.04 Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any moneys deposited with or paid to the
Trustee or any paying agent for the payment of the principal of, interest on or additional amounts in respect of any Security
of any series and not applied but remaining unclaimed for two years after the date upon which such principal, interest or additional
amount shall have become due and payable, shall be repaid to the Issuer by the Trustee for such series or such paying agent, and
the Holder of the Securities of such series shall thereafter look only to the Issuer for any payment which such Holder may be
entitled to collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease.

 

Section
10.05 Indemnity for U.S. Government Obligations. The Issuer shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 10.01 or the principal

REDEMPTION
OF SECURITIES AND SINKING FUNDS

 

Section
12.01 Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series which
are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series, except as otherwise
specified, as contemplated by Section 2.03 for Securities of such series. 

 

Section
12.02 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 Security register. Any notice which is given 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 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 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 such redemption is pursuant to the mandatory or optional sinking fund,
or both, if such be the case, 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 and shall also
specify, if applicable, the conversion price then in effect and the date on which the right to convert such Securities or the
portions thereof to be redeemed will expire. 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 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 request, by the Trustee in the name and at the expense of the Issuer.

 

On
or before 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 3.04) an amount of money sufficient to redeem on the redemption date all the Securities
of such series so called for redemption (other than those Securities theretofore surrendered for conversion into Common Stock
in accordance with their terms) at the appropriate redemption price, together with accrued interest to the date fixed for redemption.
If any Security called for redemption is converted pursuant hereto and in accordance with the terms thereof, any money deposited
with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Security shall be paid to the
Issuer upon the Issuer’s request, or, if then held by the Issuer, shall be discharged from such trust. The Issuer will deliver
to the Trustee at least 10 days prior to the date the notice required to be delivered to the Holders is to be sent (unless a shorter
time period shall be acceptable to the Trustee) an Officer’s Certificate (which need not comply with Section 11.05) stating
the aggregate principal amount of Securities to be redeemed. In case of a redemption at the election of the Issuer prior to the
expiration of any restriction on such redemption, the Issuer shall deliver to the Trustee, prior to the giving of any notice of
redemption to Holders pursuant to this Section, an Officer’s Certificate stating that such restriction has been complied
with.

 

    	 	32	 

    	 

    

 

If
less than all the Securities of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate
and fair, Securities of such series to be redeemed in whole or in part. Securities 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.
If any Security selected for partial redemption is surrendered for conversion after such selection, the converted portion of such
Security shall be deemed (so far as may be possible) to be the portion selected for redemption.

 

Section
12.03 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 such Securities
shall cease from and after the date fixed for redemption to be convertible into Common Stock (to the extent otherwise convertible
in accordance with their terms), if applicable, and cease to be entitled to any benefit or security under this Indenture, and
except as provided in the paragraph below, 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 payment of interest becoming due on or prior to 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 Sections 2.03 and 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 such Security and, if applicable, such Security shall remain convertible into
Common Stock until the principal of such Security shall have been paid or duly provided for.

 

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.

 

Section
12.04 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 an Officer’s Certificate
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 as directly or indirectly controlling or controlled by or under direct or indirect common control with
the Issuer. 

 

Section
12.05 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of
the Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in
excess of such minimum amount provided for by the terms of the Securities of any series is herein referred to as an “optional
sinking fund payment”. The date on which a sinking fund payment is to be made is herein referred to as the “sinking
fund payment date”. 

 

In
lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Issuer
may at its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon
redemption pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such series (not previously
so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer and delivered to the Trustee for
cancellation pursuant to Section 2.10 and, if applicable, receive credit for Securities (not previously so credited) converted
into Common Stock and so delivered to the Trustee for cancellation, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, or (c) receive credit for Securities of such series (not previously so
credited) redeemed by the Issuer through any optional redemption provision contained in the terms of such series. Securities so
delivered or credited shall be received or credited by the Trustee at the sinking fund redemption price specified in such Securities.

 

    	 	33	 

    	 

    

 

On
or before the 60th day next preceding each sinking fund payment date for any series, the Issuer will deliver to the Trustee an
Officer’s Certificate (which need not contain the statements required by Section 11.05) (a) specifying the portion of the
mandatory sinking fund payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities of such
series and the basis for such credit, (b) stating that none of the Securities of such series for which credit will be taken has
theretofore been so credited, (c) stating that no defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing and (d) stating whether or not the Issuer intends
to exercise its right to make an optional sinking fund payment with respect to such series and, if so, specifying the amount of
such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding sinking fund payment date.
Any Securities of such series to be credited and required to be delivered to the Trustee in order for the Issuer to be entitled
to credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant
to Section 2.10 to the Trustee with such Officer’s Certificate (or reasonably promptly thereafter if acceptable to the Trustee).
Such Officer’s Certificate shall be irrevocable and upon its receipt by the Trustee the Issuer shall become unconditionally
obligated to make all the cash payments or payments therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Issuer, on or before any such 60th day, to deliver such Officer’s Certificate and Securities
specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable
election of the Issuer that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment
date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof.

 

If
the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment
date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or the equivalent thereof
in any Foreign Currency or a lesser sum in Dollars or in any Foreign Currency if the Issuer shall so request) with respect to
the Securities of any particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption
of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption.
If such amount shall be $50,000 (or the equivalent thereof in any Foreign Currency) or less and the Issuer makes no such request
then it shall be carried over until a sum in excess of $50,000 (or the equivalent thereof in any Foreign Currency) is available,
which delay in accordance with this paragraph shall not be a default or breach of the obligation to make such payment. The Trustee
shall select, in the manner provided in Section 12.02, for redemption on such sinking fund payment date a sufficient principal
amount of Securities of such series to which such cash may be applied, as nearly as may be, and shall (if requested in writing
by the Issuer) inform the Issuer of the serial numbers of the Securities of such series (or portions thereof) so selected. The
Trustee, in the name and at the expense of the Issuer (or the Issuer, if it shall so request the Trustee in writing), shall cause
notice of redemption of the Securities of such series to be given in substantially the manner provided in Section 12.02 (and with
the effect provided in Section 12.03) for the redemption of Securities of such series in part at the option of the Issuer. The
amount of any sinking fund payments not so applied or allocated to the redemption of Securities of such series shall be added
to the next cash sinking fund payment for such series and, together with such payment, shall be applied in accordance with the
provisions of this Section. Any and all sinking fund moneys held on the stated maturity date of the Securities of any particular
series (or earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities
of such series, shall be applied, together with other moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity. The Issuer’s obligation to make a mandatory or
optional sinking fund payment shall automatically be reduced by an amount equal to the sinking fund redemption price allocable
to any Securities or portions thereof called for redemption pursuant to the preceding paragraph on any sinking fund payment date
and converted into Common Stock in accordance with the terms of such Securities; provided that, if the Trustee is not the
conversion agent for the Securities, the Issuer or such conversion agent shall give the Trustee written notice on or prior to
the date fixed for redemption of the principal amount of Securities or portions thereof so converted.

 

On
or before each sinking fund payment date, the Issuer shall pay to the Trustee in cash or shall otherwise provide for the payment
of all interest accrued to the date fixed for redemption on Securities to be redeemed on such sinking fund payment date.

 

The
Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or give any notice of redemption
of Securities for such series by operation of the sinking fund during the continuance of a default in payment of interest on such
Securities or of any Event of Default except that, where the mailing of notice of redemption of any Securities shall theretofore
have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the
Issuer a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such series at the time when
any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance
of such default or Event of Default, be deemed to have been collected under Article 5 and held for the payment of all such Securities.
In case such Event of Default shall have been waived as provided in Section 5.10, or the default cured on or before the 60th day
preceding the sinking fund payment date in any year, such moneys shall thereafter be applied on such sinking fund payment date
in accordance with this Section to the redemption of such Securities.
