FORM OF COMMON STOCK PURCHASE WARRANT

 

TAKUNG ART CO., LTD

 

	Warrant Shares: [   ]	 	Issuance Date: [   ], 2022

 

THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received, [_____________] or its assigns (the “Holder”)
is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after
[   ], 2023 (the “Initial Exercise Date”) and on or prior to 5:00 p.m. (New York City time) on [   ], 2028 (the “Termination
Date”) but not thereafter, to subscribe for and purchase from Takung Art Co., Ltd, a Delaware corporation (the “Company”),
up to two shares (as subject to adjustment hereunder, the “Warrant Shares”) of Common Stock. This Warrant is part of
units (“Units”), each Unit consisting of one share of Common Stock, par value $0.001, (the “Common Stocks”) and
Warrant to purchase two shares of Common Stock issued pursuant to that certain Securities Purchase Agreement (the “Purchase Agreement”)
entered into on June 27, 2022 and as amended on July 27, 2022 among the Company and the purchasers signatory thereto, as amended from
time to time.

 

Section 1.
 Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Purchase
Agreement.

 

Section 2. Exercise.

 

(a) Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after
the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile copy or a PDF
copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”).
Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined
in Section 2(e)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the
shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the
cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice
of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise
be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to
the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in
which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which
the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the
total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable
hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise
within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number
of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

 

    

     

    

 

(b) Exercise
Price. The exercise price of the Common Stock under this Warrant shall be $3.6125, subject to adjustment hereunder (the “Exercise
Price”).

 

(c) Cashless
Exercise. If at any time after the nine-month anniversary of the Issuance Date, there is no effective registration statement registering,
or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole
or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant
Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

 

(A) = as applicable:
(i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1)
both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant
to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of
Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, either (y) the VWAP
on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the Common Stock on the
principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise
if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours
thereafter (including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section
2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day
and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours”
on such Trading Day;

 

(B) =  the Exercise Price of
this Warrant, as adjusted hereunder; and

 

(X) =  the number
of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were
by means of a cash exercise rather than a cashless exercise.

 

If Warrant Shares are issued
in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant
Shares shall take on the characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being issued may
be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c). Without
limiting the cashless exercise provision set forth in this Section 2(c), the liquidated damages provision in Section 2(d)(i) or the buy-in
provision in Section 2(d)(iv), there is no circumstance that would require the Company to net-cash settle this Warrant.

 

“Bid Price”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or
quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading
Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York
City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the
Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed
or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported in the “Pink Sheets” published
by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid
price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined
by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and
reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

    2

     

    

 

“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or
quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date)
on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30
a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average
price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not
then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported in the “Pink Sheets”
published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent
bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined
by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and
reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

(d) [Reserved]

 

(e) Mechanics
of Exercise.

 

(i) Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company
through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system
and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant
Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant
to Rule 144 (assuming cashless exercise of the Warrants), and otherwise by physical delivery of a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to
such exercise to the address specified by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading
Days after the delivery to the Company of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price
to the Company and (iii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the
Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant
has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price
(other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. The Company agrees to maintain a transfer
agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary
Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.

 

(ii) Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant.

 

(iii) Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i)
by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

 

    3

     

    

 

(iv) No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall,
at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the
Exercise Price or round up to the next whole share.

 

(v) Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant
Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in
the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise
shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto,
the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees
required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing
corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

 

(vi) Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

 

Section 3.  Certain
Adjustments.

 

(a) Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of
Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse
stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of the Common
Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event
and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of
shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant
shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for
the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective
date in the case of a subdivision, combination or re-classification.

 

(b) Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after
the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent
that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise
of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation)
immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the
record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, that,
to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial
Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership
of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance
for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership
Limitation).

 

    4

     

    

 

(c) Number
of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section 3(a) above, the number of Warrant
Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment
the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price
in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

 

(d) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes
of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the
number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

 

(e) Notice
to Holder.

 

(i) Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

(ii) Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common
Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall
authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock
of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification
of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of
the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property,
or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company,
then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email
address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected
that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to
deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to
be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a
Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such
notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4.  Transfer
of Warrant.

 

(a) Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of
Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights)
are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent
or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing
the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full,
in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers
an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised
by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

 

(b) New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or
its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination,
the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated the initial Issuance Date of this Warrant and shall be
identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

(c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this
Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual notice to the contrary.

 

    6

     

    

 

(d) Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this
Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable
state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information
requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of
this Warrant, as the case may be, comply with the provisions of Section 5.7 of the Purchase Agreement.

 

(e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or
reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant
to sales registered or exempted under the Securities Act.

 

Section 5.  Miscellaneous.

 

(a) No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as
a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

 

(b) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

 

(c) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

 

(d) Authorized
Shares.

 

The Company covenants that,
during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares
to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants
that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary
Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be
necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or
of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which
may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented
by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue).

 

    7

     

    

 

Except and to the extent as
waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of
incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times
in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to
protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company
will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such
increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally
issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain
all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable
the Company to perform its obligations under this Warrant.

 

Before taking any action which
would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company
shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or
bodies having jurisdiction thereof.

 

(e) Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Purchase Agreement.

 

(f) Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered and the Holder does not
utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

 

(g) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as
a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this
Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results
in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder
in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

    8

     

    

 

(h) Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in
accordance with the notice provisions of the Purchase Agreement.

 

(i) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the
Company.

 

(j) Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any
action for specific performance that a remedy at law would be adequate.

 

(k) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant Shares.

 

(l) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

(m) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

 

(n) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

the case of Securities of a Series to be issued from time to time, the Board Resolution, Officer’s Certificate or supplemental
indenture establishing the terms thereof may provide for the method by which specified terms (such as interest rate, maturity date, record
date or date from which interest shall accrue) are to be determined. Securities may differ between Series in respect of any matters,

All
Securities of any one Series need not be issued at the same time and may be issued from time to time, consistent with the terms of this
Indenture, if so provided by or pursuant to the Board Resolution, supplemental indenture hereto or Officer’s Certificate referred
to above.

 

Section
2.3  Denominations; Provision for Payment.

 

The
Securities of any Series shall be issuable, except as otherwise provided with respect to Securities of any Series pursuant to Section
2.2, as registered Securities in the denominations of one thousand Dollars ($1,000) or any integral multiples of $1,000 in excess thereof.
Unless otherwise provided with respect to Securities of any Series pursuant to Section 2.2, the principal of and the interest on the
Securities of any Series, if any, thereon, shall by payable in Dollars at the Corporate Trust Office of the Trustee. Unless otherwise
specified pursuant to Section 2.2 with respect to any Securities of any Series, interest on the Securities of any Series shall be computed
on the basis of a 360-day year consisting of twelve 30-day months.

 

Section
2.4  Execution and Authentication.

 

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

 

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

 

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

 

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

 

    	7

     

    

 

The
aggregate principal amount of Securities of any Series outstanding at any time may not exceed any limit upon the maximum principal amount
for such Series set forth in the Board Resolution, supplemental indenture hereto or Officer’s Certificate delivered pursuant to
Section 2.2, except as provided in Section 2.9.

 

Prior
to the issuance of Securities of any Series, the Trustee shall have received and (subject to Section 7.1) shall be fully protected in
conclusively relying on: (a) the Board Resolution, supplemental indenture hereto or Officer’s Certificate delivered pursuant to
Section 2.2 establishing the form of the Securities of that Series or of Securities within that Series and the terms of the Securities
of that Series or of Securities within that Series, (b) an Officer’s Certificate complying with Section 9.7 (with respect to the
execution of supplemental indentures) and Section 10.4, and (c) an Opinion of Counsel complying with Section 9.7 (with respect to the
execution of supplemental indentures) and Section 10.4.

 

The
Trustee shall have the right, but not the obligation, to decline to authenticate and deliver any Securities of such Series: (a) if the
Trustee, being advised by counsel, determines that such action may not be taken lawfully; or (b) if the Trustee in good faith determines
that such action would expose the Trustee to personal liability.

 

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

 

Section
2.5  Registrar and Paying Agent.

 

The
Company shall maintain, with respect to each Series of Securities, at the place or places specified with respect to such Series, an office
or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”) and where Securities
of such Series may be surrendered for registration of transfer or exchange (“Registrar”). The Registrar shall keep
a register with respect to each Series of Securities and to their transfer and exchange (the “Security Register”).
The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar
or Paying Agent. If at any time the Company shall fail to maintain any such required Registrar or Paying Agent or shall fail to furnish
the Trustee with the name and address thereof, such presentations and surrenders may be made or served at the Corporate Trust Office
of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations and surrenders.

 

The
Company may also from time to time designate one or more co-registrars or additional paying agents and may from time to time rescind
such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of
its obligations to maintain a Registrar or Paying Agent in each place so specified for Securities of any Series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address
of any such co-registrar or additional paying agent. The term “Registrar” includes any co-registrar; and the term
“Paying Agent” includes any additional paying agent. The Company or any of its Affiliates may serve as Registrar or
Paying Agent.

 

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

 

    	8

     

    

 

Section
2.6 Paying Agent to Hold Money in Trust.

 

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

 

Section
2.7  Securityholder Lists.

 

The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses
of Securityholders of each Series of Securities and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar,
the Company shall furnish to the Trustee at least ten days before each interest payment date and at such other times as the Trustee may
request in writing, within 30 days after receipt by the Company of any such request, a list, in such form and as of such date as the
Trustee may reasonably require, of the names and addresses of Securityholders of each Series of Securities.

 

Section
2.8  Transfer and Exchange.

 

Where
Securities of a Series are presented to the Registrar or a co-registrar with a request to register a transfer or to exchange them for
an equal principal amount of Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements
for such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s
request. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein),
but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.12, 3.6 or 9.6).

 

Neither
the Company nor the Registrar shall be required (a) to issue, register the transfer of, or exchange Securities of any Series for the
period beginning at the opening of business 15 days immediately preceding the mailing of a notice of redemption of Securities of that
Series selected for redemption and ending at the close of business on the day of such mailing, or (b) to register the transfer of or
exchange Securities of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such
Securities selected, called or being called for redemption in part.

 

Section
2.9  Mutilated, Destroyed, Lost and Stolen Securities.

 

If
any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

 

    	9

     

    

 

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

 

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

 

Upon
the issuance of any new Security under this Section 2.9, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee)
connected therewith.

 

Every
new Security of any Series issued pursuant to this Section 2.9 in lieu of any destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other
Securities of that Series duly issued hereunder.

 

The
provisions of this Section 2.9 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

 

Section
2.10  Outstanding Securities.

 

The
Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by the Registrar and
those described in this Section 2.10 as not outstanding.

 

If
a Security is replaced pursuant to Section 2.9, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that
the replaced Security is held by a bona fide purchaser.

 

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

 

The
Company may purchase or otherwise acquire the Securities, whether by open market purchases, negotiated transactions or otherwise. A Security
does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

 

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

 

Section
2.11  Treasury Securities.

 

In
determining whether the Holders of the required principal amount of Securities of a Series have concurred in any request, demand,
authorization, direction, notice, consent or waiver, Securities of a Series owned by the Company or any Affiliate of the Company
shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in conclusively relying on
any such request, demand, authorization, direction, notice, consent or waiver, only Securities of a Series that a Responsible
Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good
faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver
any such request, demand, authorization, direction, notice, consent or waiver with respect to the Securities and that the pledgee is
not the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor.

 

    	10

     

    

 

Section
2.12  Temporary Securities.

 

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

 

Section
2.13  Cancellation.

 

The
Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent, if not the Trustee, shall
forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel
all Securities surrendered for transfer, exchange, payment, replacement, conversion or cancellation and shall dispose of such canceled
Securities (subject to the record retention requirement of the Exchange Act and the Trustee) in accordance with its customary procedures
and deliver a certificate of such cancellation to the Company upon written request of the Company. The Company may not issue new Securities
to replace Securities that it has paid or delivered to the Trustee for cancellation.

 

Section
2.14  Defaulted Interest.

 

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

 

Section
2.15  Global Securities.

 

2.15.1.
Terms of Securities. A Board Resolution, a supplemental indenture hereto or an Officer’s Certificate shall establish whether
the Securities of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such
Global Security or Securities.

 

2.15.2. Transfer
and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.8 of this Indenture and in addition thereto,
any Global Security shall be exchangeable pursuant to Section 2.8 of this Indenture for Securities registered in the names of
Holders other than the Depositary for such Security or its nominee only if (a) such Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing
agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary registered as a
clearing agency under the Exchange Act within 90 days of such event or (b) the Company determines in its sole discretion not to have
such Securities represented by one or more Global Securities and executes and delivers to the Trustee an Officer’s Certificate
to the effect that such Global Security shall be so exchangeable. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as the Depositary shall direct in writing in an aggregate
principal amount equal to the principal amount of the Global Security with like tenor and terms.

 

    	11

     

    

 

Except
as provided in this Section 2.15.2, a Global Security may not be transferred except as a whole by the Depositary with respect to such
Global Security to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary
or by the Depositary or any such nominee to a successor Depositary or a nominee of such a successor Depositary.

 

2.15.3.
Legend. Any Global Security issued hereunder shall bear a legend in substantially the following form:

 

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

 

2.15.4.
Acts of Holders. The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Indenture.

 

2.15.5.
Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.2, payment
of the principal of and interest, if any, on any Global Security shall be made to the Holder thereof, which in the case of a Depositary
therefor will be made in accordance with its applicable procedures.

 

2.15.6.
Consents, Declaration and Directions. The Company, the Trustee and any Agent shall treat a person as the Holder of such principal
amount of outstanding Securities of such Series represented by a Global Security as shall be specified in a written statement of the
Depositary or by the applicable procedures of such Depositary with respect to such Global Security, for purposes of obtaining any consents,
declarations, waivers or directions required to be given by the Holders pursuant to this Indenture.

 

Section
2.16  CUSIP Numbers.

 

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

 

    	12

     

    

 

Section
2.17 Evidence of Ownership.

 

The
Company, the Trustee and any agent of the Company or the Trustee may deem and treat the person in whose name any registered Security
shall be registered upon the Security Register for such series as the absolute owner of such registered Security (whether or not such
registered 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 registered Security and
for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any
notice to the contrary.

 

ARTICLE
3

REDEMPTION

 

Section
3.1  Notice to Trustee.

 

The
Company may, with respect to any Series of Securities, reserve the right to redeem and pay the Series of Securities or may covenant to
redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided
for in such Securities. If a Series of Securities is redeemable and the Company wants or is obligated to redeem prior to the Stated Maturity
thereof all or part of the Series of Securities pursuant to the terms of such Securities, it shall notify the Trustee in writing of the
redemption date and the principal amount of Series of Securities to be redeemed. The Company shall give the notice to the Trustee at
least 45 days before the redemption date, unless a shorter period is specified in the Securities to be redeemed.

 

Section
3.2  Selection of Securities to be Redeemed.

 

Unless
otherwise indicated for a particular Series by a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate,
if less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of the Series to be redeemed
in any manner that the Trustee deems fair and appropriate, including selecting by lot or other method, unless otherwise required by law
or applicable stock exchange requirements, subject, in the case of Global Securities, to the applicable rules and procedures of the Depositary;
provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall
not be less than the minimum authorized denomination) for such Security. The Trustee shall make the selection from Securities of the
Series outstanding not previously called for redemption. Provisions of this Indenture that apply to Securities of a Series called for
redemption also apply to portions of Securities of that Series called for redemption.

 

Section
3.3  Notice of Redemption.

 

Unless
otherwise indicated for a particular Series by Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, at
least 15 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to
each Holder whose Securities are to be redeemed.

 

The
notice shall identify the Securities of the Series to be redeemed and shall state:

 

(a)
the redemption date;

 

(b)
the redemption price and the amount of accrued interest, if any, to be paid;

 

(c)
the name and address of the Paying Agent and, if applicable, the conversion Agent;

 

(d)
for convertible Securities, the conversion price;

 

    	13

     

    

 

(e)
if any Global Security is being redeemed in part, the portion of the principal amount of such Global Security to be redeemed and that,
after the redemption date upon surrender of such Global Security, the principal amount thereof will be decreased by the portion thereof
redeemed pursuant thereto;

 

(f)
if any Certificated Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed, and that,
after the redemption date, upon surrender of such Security, a new Certificated Security in principal amount equal to the unredeemed portion
thereof will be issued in the name of the Holder thereof upon cancellation of the original Certificated Security;

 

(g)
that Securities of the Series (or portion thereof) called for redemption must be surrendered to the Paying Agent to collect the redemption
price;

 

(h)
that interest on Securities of the Series called for redemption ceases to accrue on and after the redemption date, subject to the satisfaction
of any conditions to such redemption, unless the Company defaults in the deposit of the redemption price;

 

(i)
the CUSIP number, if any, and state that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed
in the SEC’s notice or printed on the Securities; and

 

(j)
any other information as may be required by the terms of the particular Series or the Securities of a Series being redeemed.

 

At
the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense, provided,
however, that the Company has delivered to the Trustee, at least 15 days (unless a shorter time shall be acceptable to the Trustee)
prior to the notice date, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information
to be stated in such notice.

 

Section
3.4  Effect of Notice of Redemption.

 

Once
notice of redemption is mailed as provided in Section 3.3, Securities of a Series called for redemption become due and payable on the
redemption date and at the redemption price. Except as otherwise provided in the supplemental indenture, Board Resolution or Officer’s
Certificate for a Series, a notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Securities shall be
paid at the redemption price plus accrued interest to the redemption date other than Securities or portions of Securities called for
redemption which have been delivered by the Company to the Registrar for cancellation. The Paying Agent shall return to the Company any
money not required for that purpose.

 

To
the extent provided for in the supplemental indenture, Board Resolution or Officer’s Certificate for a Series, in connection with
any redemption of Securities of a Series, any such redemption may, at the Company’s discretion, be subject to one or more conditions
precedent, such as refinancings, acquisitions or equity offerings. In addition, if such redemption or notice is subject to satisfaction
of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed
until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or such redemption
may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived
by the Company in its sole discretion) by the redemption date, or by the redemption date so delayed.

 

Unless
the Company shall default in the payment of Securities (and accrued interest) called for redemption, interest on such Securities
shall cease to accrue after the redemption date, subject to the satisfaction of any conditions to the redemption to the extent that
conditional redemption is provided for in the supplemental indenture, Board Resolution or Officer’s Certificate for a Series.
Convertible Securities called for redemption shall cease to be convertible after the close of business on the Business Day
immediately preceding the redemption date, unless the Company shall default in the payment of such Securities on the redemption
date, in which event the Securities shall remain convertible until paid (together with accrued interest).

 

    	14

     

    

 

Failure
to give notice of redemption, or any defect in such notice to the Holder of any Security of a Series designated for redemption, in whole
or in part, shall not affect the sufficiency of any notice of redemption with respect to the Holder of any other Security of such Series.

 

Section
3.5  Deposit of Redemption Price.

 

On
or before 10:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent money sufficient to
pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date subject to the satisfaction of
any conditions to such redemption.

 

Section
3.6  Securities Redeemed in Part.

 

Upon
surrender of a Certificated Security that is redeemed in part, the Trustee shall authenticate for the Holder a new Certificated Security
of the same Series and the same maturity equal in principal amount to the unredeemed portion of the Security surrendered and concurrently
cancel the surrendered Certificated Security.

stating, as to such Officer signing such certificate, that to his or her knowledge the Company is not in default in the performance or
observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing

which may affect the covenants or the performance of this Indenture or the Securities; and the Company (to the extent it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder,

as though no such law has been enacted.

“Event
of Default,” wherever used herein with respect to Securities of any Series, means any one of the following events, unless in
the establishing Board Resolution, supplemental indenture or Officer’s Certificate, it is provided that such Series shall not have
the benefit of said Event of Default:

 

(a)
failure to pay any interest on any Security of that Series when it becomes due and payable, and continuance of such default for a period
of 30 days (unless the entire amount of such payment is deposited by the Company with the Trustee or with a Paying Agent prior to 10:00
a.m., New York City time, on the 30th day of such period);

 

(b)
failure to pay principal of any Security of that Series at its Maturity;

 

(c)
default in the performance or breach of any covenant of the Company in this Indenture (other than defaults pursuant to sub-clauses (a)
through (b) above or defaults related to a covenant that has been included in this Indenture solely for the benefit of a Series of Securities
other than that Series), which default continues uncured for a period of 90 days after there has been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding
Securities of that Series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice
is a “Notice of Default” hereunder;

 

    	17

     

    

 

(d)
the Company pursuant to or within the meaning of any Bankruptcy Law:

 

(i)
commences a voluntary case,

 

(ii)
consents to the entry of an order for relief against it in an involuntary case,

 

(iii)
consents to the appointment of a Custodian of it or for all or substantially all of its property, or

and

(f)
any other Event of Default provided with respect to Securities of that Series, which is specified in a Board Resolution, a supplemental
indenture hereto or an Officer’s Certificate, in accordance with Section 2.2.18.

 

The
term “Bankruptcy Law” means title 11, U.S. Code or any similar federal or state law for the relief of debtors. The
term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.

 

A
Default under one Series of Securities issued under this Indenture will not necessarily be a default under another Series of Securities
under this Indenture.

 

The
Company will, so long as any of the Securities are outstanding, deliver to the Trustee, within 30 days of becoming aware of any Default
or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking
or proposes to take with respect thereto.

 

Section
6.2  Acceleration of Maturity; Rescission and Annulment.

 

If
an Event of Default with respect to Securities of any Series at the time outstanding occurs and is continuing (other than an Event of
Default referred to in Section 6.1(d) or (e)) then in every such case the Trustee or the Holders of not less than 25% in principal amount
of the outstanding Securities of that Series may declare the principal amount (or, if any Securities of that Series are Discount Securities,
such portion of the principal amount as may be specified in the terms of such Securities) of and accrued and unpaid interest, if any,
on all of the Securities of that Series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest, if any,
shall become immediately due and payable. If an Event of Default specified in Section 6.1(d) or (e) shall occur, the principal amount
(or specified amount) of and accrued and unpaid interest, if any, on all outstanding Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

 

At
any time after such a declaration of acceleration with respect to any Series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in
principal amount of the outstanding Securities of that Series, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if all Events of Default with respect to Securities of that Series, other than the
non-payment of the principal and interest, if any, of Securities of that Series which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 6.13.

 

    	18

     

    

 

No
such rescission shall affect any subsequent Default.

 

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

 

The
Company covenants that if

 

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

 

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

 

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

 

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

 

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

 

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

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

 

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

 

    	19

     

    

 

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

 

and
any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7.

 

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

 

Section

of Securities.

 

All
rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit
of the Holders of the Securities in respect of which such judgment has been recovered.

 

Section
6.6  Application of Money Collected.

 

Any
money or property collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed
by the Trustee and, in case of the distribution of such money or property on account of principal or interest, upon presentation of the
Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

 

First:
To the payment of all amounts due to the Trustee under this Indenture; and

 

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

 

Third:
To the Company.

 

Section
6.7  Limitation on Suits.

 

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

 

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

 

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

 

    	20

     

    

 

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

 

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

 

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

 

it
being understood, intended and expressly covenanted by the Holder of every Security with every other Holder and the Trustee that no one
or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture
to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over
any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders of the applicable Series; provided, however, that the Trustee does not have an affirmative
duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders.

 

Section
6.8  Unconditional Right of Holders to Receive
Principal and Interest.

 

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

 

Section
6.9  Restoration of Rights and Remedies.

 

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

 

Section

Except
as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.9, no
right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder,
or otherwise, shall not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right
or remedy.

 

Section
6.11  Delay or Omission Not Waiver.

 

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

 

    	21

     

    

 

Section
6.12  Control by Holders.

Holders of a majority in principal amount of the outstanding Securities of any Series shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee,
with respect to the Securities of such Series, provided that:

 

(a)
such direction shall not be in conflict with any rule of law or with this Indenture;

 

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

 

(c)
subject to the provisions of Section 7.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in
good faith shall, by a Responsible Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal
liability; and

 

(d)
prior to taking any action as directed under this Section 6.12, the Trustee shall be entitled to indemnity satisfactory to it against
the costs, expenses, and liabilities which might be incurred by it in compliance with such request or direction.

The
Holders of not less than a majority in principal amount of the outstanding Securities of any Series may on behalf of the Holders of all
the Securities of such Series waive any past Default hereunder with respect to such Series and its consequences, except a Default in
the payment of the principal of or interest on any Security of such Series (provided, however, that the Holders of a majority
in principal amount of the outstanding Securities of any Series may rescind an acceleration and its consequences, including any related
payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent
or other Default.

 

Section
6.14  Undertaking for Costs.

 

All
parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the
Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to
pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’
fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; but the provisions of this Section 6.14 shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the outstanding Securities of any Series, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or interest on any Security on or after the Maturity of such Security, including the Stated Maturity expressed in such Security
(or, in the case of redemption, on the redemption date).

7.1 Duties of Trustee.

 

(a)
If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture

The Trustee need perform only those duties that are specifically set forth in this Indenture and no others.

requirements of this Indenture; however, in the case of any such Officer’s Certificates or Opinions of Counsel which by
any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officer’s Certificates
and Opinions of Counsel to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate
the accuracy of mathematical calculations or other facts stated therein).

 

(c)
The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,

(h)
The Paying Agent, the Registrar and any authenticating agent shall be entitled to the protections and immunities as are set forth in

Section
7.3  Individual Rights of Trustee.

 

The
Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company
or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights.
However, the Trustee is also subject to Sections 7.10 and 7.11 hereof.

 

Section
7.4  Trustee’s Disclaimer.

 

The
Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the
Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than
its authentication.

 

Section
7.5  Notice of Defaults.

 

If
a Default or Event of Default occurs and is continuing with respect to the Securities of any Series and if it is actually known to a
Responsible Officer of the Trustee, the Trustee shall mail to each Securityholder of the Securities of that Series notice of a Default
or Event of Default within 90 days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge of such Default
or Event of Default. Except in the case of a Default or Event of Default in payment of principal of or interest on any Security of any
Series, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests
of Securityholders of that Series.

 

Section
7.6  Reports by Trustee to Holders.

 

Within
60 days after each anniversary of the date of this Indenture, the Trustee shall transmit by mail to all Securityholders, as their names
and addresses appear on the register kept by the Registrar, a brief report dated as of such reporting date, in accordance with, and to
the extent required under, TIA § 313. A copy of each report at the time of its mailing to Securityholders of any Series shall be
filed with the SEC and each national securities exchange on which the Securities of that Series are listed. The Company shall promptly
notify the Trustee in writing when Securities of any Series are listed on any national securities exchange or of any delisting thereof.

 

Section
7.7  Compensation and Indemnity.

 

The
Company shall pay to the Trustee from time to time compensation for its services as the Company and the Trustee shall from time to time
agree upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.
The Company shall reimburse the Trustee upon request for all reasonable out of pocket expenses incurred by it. Such expenses shall include
the reasonable compensation and expenses of the Trustee’s agents and counsel.

 

The
Company shall indemnify each of the Trustee and any predecessor Trustee against any cost, expense, claim (whether asserted by the Company,
a Holder or any other person) or liability (including the cost of defending itself), including taxes (other than taxes based upon, measured
by or determined by the income of the Trustee), incurred by it except as set forth in the next paragraph in the performance of its duties
under this Indenture as Trustee or Agent. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless and to the extent
that the Company is materially prejudiced thereby. The Company shall defend the claim and the Trustee shall cooperate in the defense.
The Trustee may have one separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need
not pay for any settlement made without its consent, which consent will not be unreasonably withheld. This indemnification shall apply
to officers, directors, employees, shareholders and agents of the Trustee.

 

    	25

     

    

 

The
Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director,
employee or shareholder of the Trustee through willful misconduct or negligence.

 

To
secure the Company’s payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Securities of any Series
on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on particular Securities
of that Series.

 

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

 

The
provisions of this Section 7.7 shall survive the termination of this Indenture or the resignation or removal of the Trustee.

 

Section
7.8  Replacement of Trustee.

 

A
resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.8.

 

The
Trustee may resign at any time with respect to the Securities of one or more Series by so notifying the Company at least 30 days prior
to the date of the proposed resignation. The Holders of a majority in principal amount of the Securities of any Series may remove the
Trustee with respect to that Series by so notifying the Trustee and the Company in writing. The Company may remove the Trustee with respect
to Securities of one or more Series if:

 

(a)
the Trustee fails to comply with Section 7.10;

 

(b)
the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

 

(c)
a Custodian or public officer takes charge of the Trustee or its property; or

 

(d)
the Trustee becomes incapable of acting.

 

If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint
a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then
outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

 

If
a successor Trustee with respect to the Securities of any one or more Series does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the Securities
of the applicable Series may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of
the Company.

 

A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately
after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to the lien
provided for in Section 7.7, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee
shall have all the rights, powers and duties of the Trustee with respect to each Series of Securities for which it is acting as
Trustee under this Indenture. A successor Trustee shall mail a notice of its succession to each Securityholder of each such Series.
Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof
shall continue for the benefit of the retiring Trustee with respect to expenses and liabilities incurred by it for actions taken or
omitted to be taken in accordance with its rights, powers and duties under this Indenture prior to such replacement.

Section
7.9  Successor Trustee by Merger, Etc. 

 

If
the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the successor Trustee, if such successor corporation is eligible
and qualified under Section 7.10.

 

Section

This
Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee shall always have
a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition. The Trustee
shall comply with TIA § 310(b).

 

Section
7.11  Preferential Collection of Claims Against Company.

 

The
Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned
or been removed shall be subject to TIA § 311(a) to the extent indicated.

or Foreign Government Obligations or money were deposited or received. This provision shall not authorize the sale by the Trustee of
any U.S. Government Obligations or Foreign Government Obligations held under this Indenture.

 

Section
8.3  Legal Defeasance of Securities of any Series.

 

Unless
this Section 8.3 is otherwise specified, pursuant to Section 2.2, to be inapplicable to Securities of any Series, the Company shall be

certification thereof delivered to the Trustee, to pay and discharge each installment of principal of and interest, if any, on and any
mandatory sinking fund payments in respect of all the Securities of such Series on the dates such installments of interest or principal

4.4 and 5.1 as well as any additional covenants specified in a supplemental indenture for such Series of Securities or a Board
Resolution or an Officer’s Certificate delivered pursuant to Section 2.2 (and the failure to comply with any such covenants
shall not constitute a Default or Event of Default with respect to such Series under Section 6.1) and the occurrence of any event
specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officer’s Certificate
delivered pursuant to Section 2.2.18 and designated as an Event of Default shall not constitute a Default or Event of Default

of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent certified public accountants or
investment bank expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal
of and interest, if any, on and any mandatory sinking fund payments in respect of the Securities of such Series on the dates such installments
of interest or principal and such sinking fund payments are due;

After that, Securityholders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned
property law designates another person.

 

Section
8.6  Reinstatement.

 

If
the Trustee or the Paying Agent is unable to apply any money deposited with respect to Securities of any Series in accordance with
Section 8.1 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture with respect
to the Securities of such Series and under the Securities of such Series shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.1 until such time as the Trustee or the Paying Agent is permitted to apply all such money in
accordance with Section 8.1; provided, however, that if the Company has made any payment of principal of or interest
on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent after
payment in full to the Holders.

to the benefit of such provision.

 

Section
9.2  With Consent of Holders.

 

The
Company and the Trustee may enter into a supplemental indenture with the written consent of the Holders of at least a majority in
principal amount of the outstanding Securities of each Series affected by such supplemental indenture (including consents obtained
in connection with a tender offer or exchange offer for the Securities of such Series), for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Securityholders of each such Series. Except as provided in Section 6.13, the Holders of at least a

with any provision of this Indenture or the Securities with respect to such Series.

 

    	31

     

    

 

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

the consent of each Securityholder affected, an amendment or waiver may not:

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

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

Every
amendment to this Indenture or the Securities of one or more Series shall be set forth in a supplemental indenture hereto that complies
with the TIA as then in effect.

 

Section
9.5  Revocation and Effect of Consents.

 

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

 

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

 

    	32

     

    

 

The
Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated
proxies), and only those persons, shall be entitled to give such consent or to revoke any consent previously given or take any such action,
whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than
120 days after such record date.

 

Section
9.6  Notation on or Exchange of Securities.

 

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

 

Section
9.7  Trustee Protected.

 

In

by the Holders of a specified percentage in aggregate principal amount of Securities of all Series or all Series affected by a particular
action at the time outstanding and, at such time, there are outstanding Securities of any Series which are denominated in more than one

action shall be determined by converting any such other currency into a currency that is designated upon issuance of any particular Series
of Securities. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate delivered
pursuant to Section 2.2 of this Indenture with respect to a particular Series of Securities, such conversion shall be at the spot rate

judgment in any court it is necessary to convert the sum due in respect of the principal of or interest or other amount on the
Securities of any Series (the “Required Currency”) into a currency in which a judgment will be rendered (the
“Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the day on which
final unappealable judgment is entered, unless such day is not a Business Day, then the rate of exchange used shall be the rate at
which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the Business Day preceding the day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full
amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt
shall fall short of the full amount of the Required Currency so expressed to be payable, and (iii) shall not be affected by judgment
being obtained for any other sum due under this Indenture.

acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or
malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use
reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable
under the circumstances.

identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this Indenture

SINKING FUNDS

 

Section
11.1  Applicability of Article.

 

The
provisions of this Article shall be applicable to any sinking fund for the retirement of the Securities of a Series if so provided by
the terms of such Securities pursuant to Section 2.2 and except as otherwise permitted or required by any form of Security of such Series
issued pursuant to this Indenture.

 

The
minimum amount of any sinking fund payment provided for by the terms of the Securities of any Series is herein referred to as a “mandatory
sinking fund payment” and any other amount provided for by the terms of Securities of such Series is herein referred to as
an “optional sinking fund payment.” If provided for by the terms of Securities of any Series, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 11.2. Each sinking fund payment shall be applied to the redemption
of Securities of any Series as provided for by the terms of the Securities of such Series.

 

    	37

     

    

 

Section
11.2  Satisfaction of Sinking Fund Payments with Securities.

 

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

 

Section
11.3  Redemption of Securities for Sinking Fund.

 

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