Secured
Convertible Debenture


 


Face Amount: $1,000,000 


Purchase Price: $960,000



Debenture Issuance Date: December 31,
2019


Debenture Number: IDEX-2


 


FOR VALUE RECEIVED,
IDEANOMICS, INC., a Nevada corporation (the “Company”),
hereby promises to pay to the order of YA II PN, LTD., or its registered assigns (the “Holder”) the amount
set out above as the Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise,
the “Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise
(in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal
at the applicable Interest Rate from the date set out above as the Debenture Issuance Date (the “Issuance Date”)
until the same becomes due and payable, whether upon an Interest Date (as defined below), the Maturity Date or acceleration, conversion,
redemption or otherwise (in each case in accordance with the terms hereof). This Secured Convertible Debenture (including all debentures
issued in exchange, transfer or replacement hereof, this “Debenture”) was originally issued pursuant to the
Securities Purchase Agreement dated December 13, 2019, (the “Securities Purchase Agreement”) between the Company
and the Buyers listed on the Schedule of Buyers attached thereto. Certain capitalized terms used herein are defined in Section
16. For the avoidance of doubt, the Issuance Date is the date of the first issuance of this Debenture regardless of the number
of transfers and regardless of the number of instruments, which may be issued to evidence such Debenture. This Debenture is being
issued in connection with the Second Closing Date (as such term is defined in the Securities Purchase Agreement).


 


(1) GENERAL TERMS


 


(a) Maturity Date. The “Maturity Date” shall be December 31, 2020, as may be extended at the option
of the Holder.


 






    	 	 	 



     


    

 


(b) Interest Rate and Payment of Interest. Interest shall accrue on the outstanding principal balance hereof at an annual
rate equal to 4% (“Interest Rate”). Interest shall be calculated on the basis of a 365-day year and the actual
number of days elapsed, to the extent permitted by applicable law.


 


(c) Security. This Debenture is secured by a grant of a security interest and a mortgage as set forth in the Securities
Purchase Agreement.


 


(d) Redemption. The Company shall have the right, but not the obligation, to redeem (“Optional Redemption”)
a portion or all amounts outstanding under this Debenture prior to the Maturity Date as described in this Section; provided
that the Company provides each Buyer with at least 15 Business Days’ prior written notice (each, a “Redemption Notice”)
of its desire to exercise an Optional Redemption and the VWAP of the Company’s Common Stock over the 10 Business Days’
immediately prior to the Redemption Notice is less than the Fixed Conversion Price. Each Redemption Notice shall be irrevocable
and shall specify the outstanding balance of the Convertible Debentures to be redeemed (principal plus accrued but unpaid interest
through the date of redemption), plus a redemption premium equal to 15% of the amount being redeemed (collectively, the amount
being redeemed plus the redemption premium is the “Redemption Amount”). The Optional Redemption shall be consummated
by a wire transfer by the Company to the Holder of the Redemption Amount (or such lesser amount, if the Holder has converted any
part of this Debenture during the 15-Business Day notice period specified herein) on the first Business Day following the expiration
of the 15-Business Day notice period specified herein. The Holder may convert all or any part of this Debenture after receiving
a Redemption Notice, in which case the Redemption Amount shall be reduced by the amount so converted.

and the Holder may immediately enforce any and all of its rights and remedies hereunder and all other remedies available to it
under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder. No such

(3) CONVERSION OF DEBENTURE.This Debenture shall be convertible into shares of the Company's Common Stock, on the
terms and conditions set forth in this Section 3.


 


(a) Conversion Right. Subject to the provisions of Section 3(c), at any time or times on or after the Issuance Date,
the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully
paid and nonassessable shares of Common Stock in accordance with Section 3(b), at the Conversion Rate (as defined below). The number
of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to this Section 3(a) shall be determined by
dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”). The Company shall not
issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of
a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to the nearest whole share.
The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery
of Common Stock upon conversion of any Conversion Amount.


 


(i) “Conversion Amount” means the portion of the Principal and accrued Interest to be converted, redeemed
or otherwise with respect to which this determination is being made.


 


(b) “Conversion Price” means, as of any Conversion Date (as defined below) the lower of (a) $1.50 (the “Fixed
Conversion Price”) or (b) 90% of the lowest daily VWAP as reported by Bloomberg, LP for the 10 trading consecutive Trading
Days immediately (as defined herein) preceding the Conversion Date (the “Variable Conversion Price,” and together
with the Fixed Conversion Price, the “Conversion Price”). The Variable Conversion Price shall be subject to
a minimum price of $1.00 per share (the “Floor Price”). The Conversion Price shall be adjusted from time to
time pursuant to the other terms and conditions of this Debenture.


 






    	 	4	 



     


    

 


(c) Mechanics of Conversion.


 


(i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion
Date”), the Holder shall (A) transmit by facsimile with confirmation of delivery (or otherwise deliver by method set
forth in Section 6(A)(i) or (ii)), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice
of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and (B)
if required by Section 3(c)(iii), surrender this Debenture to a nationally recognized overnight delivery service for delivery to
the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Debenture in the case
of its loss, theft or destruction). On or before the third (3rd) Business Day following the date of receipt of a Conversion
Notice (the “Share Delivery Date”), the Company shall (X) if legends are not required to be placed on certificates
of Common Stock and provided that the Transfer Agent is participating in the Depository Trust Company's (“DTC”)
Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock to which the Holder shall be
entitled to the Holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y)
if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address
as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares
of Common Stock to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required
pursuant to rules and regulations of the Commission. If this Debenture is physically surrendered for conversion and the outstanding
Principal of this Debenture is greater than the Principal portion of the Conversion Amount being converted, then the Company shall
as soon as practicable and in no event later than three (3) Business Days after receipt of this Debenture and at its own expense,
issue and deliver to the holder a new Debenture representing the outstanding Principal not converted. The Person or Persons entitled
to receive the shares of Common Stock issuable upon a conversion of this Debenture shall be treated for all purposes as the record
holder or holders of such shares of Common Stock upon the transmission of a Conversion Notice.


 


(ii) Company's Failure to Timely Convert. If within three (3) Trading Days after the Company's receipt of a copy of a
Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder's balance account
with DTC for the number of shares of Common Stock to which the Holder is entitled upon such holder's conversion of any Conversion
Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market
transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion
that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3)
Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to
the Holder's total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of
Common Stock so purchased (the “Buy-In Price”), at which point the Company's obligation to deliver such certificate
(and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate
or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In
Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the Conversion Date.


 






    	 	5	 



     


    

 


(iii) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Debenture
in accordance with the terms hereof, the Holder shall not be required to physically surrender this Debenture to the Company unless
(A) the full Conversion Amount represented by this Debenture is being converted or (B) the Holder has provided the Company with
prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Debenture upon physical
surrender of this Debenture. The Holder and the Company shall maintain records showing the Principal and Interest converted and
the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not
to require physical surrender of this Debenture upon conversion.


 


(d) Limitations on Conversions.


 


(i) Conversions Below the Fixed Conversion Price. Absent an Event of Default or the Company’s prior consent, the
Holder may not convert more than $600,000 (of Principal, Interest or both) of this Debenture during any calendar month.


 


(ii) Beneficial Ownership. The Holder shall not have the right to convert any portion of this Debenture or receive shares
of Common Stock as payment of Interest hereunder to the extent that after giving effect to such conversion or receipt of such Interest
payment, the Holder, together with any affiliate thereof, would beneficially own (as determined in accordance with Section 13(d)
of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of shares of Common Stock outstanding
immediately after giving effect to such conversion or receipt of shares as payment of interest. Since the Holder will not be obligated
to report to the Company the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion
at issue would result in the issuance of shares of Common Stock in excess of 4.99% of the then outstanding shares of Common Stock
without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have
the authority, responsibility and obligation to determine whether the restriction contained in this Section will limit any particular
conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination
of which portion of the Principal amount of this Debenture is convertible shall be the responsibility and obligation of the Holder.
The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than
65 days prior notice to the Company. Other Holders shall be unaffected by any such waiver.


 


(e) Other Provisions.


 


(i) The Company shall at all times reserve and keep available out of its authorized Common Stock the full number of shares of
Common Stock issuable upon conversion of all outstanding amounts under this Debenture; and within three (3) Business Days following
the receipt by the Company of a Holder's notice that such minimum number of Underlying Shares is not so reserved, the Company shall
promptly reserve a sufficient number of shares of Common Stock to comply with such requirement.


 


(ii) All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.


 






    	 	6	 



     


    

 


(iii) The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of
Common Stock solely for the purpose of issuance upon conversion of this Debenture and payment of Interest on this Debenture, each
as herein provided, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder,
not less than such number of shares of the Common Stock as shall be issuable (taking into account the adjustments and restrictions
set forth herein) upon the conversion of the outstanding principal amount of this Debenture and payment of Interest hereunder.
The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized,
issued and fully paid, nonassessable and, if the Underlying Shares Registration Statement has been declared effective under the
Securities Act, registered for public sale in accordance with such Underlying Shares Registration Statement.


 


(iv) Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section
2 herein for the Company’s failure to deliver certificates representing shares of Common Stock upon conversion within the
period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or
provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant
to any other Section hereof or under applicable law.


 


(v) Conversion Costs. The Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection
with any legal opinions paid for by the Holder in connection with sale of Underlying Shares of Common Stock (provided that the
Company has first had the opportunity to obtain such a legal opinion on behalf of the Holder). The Holder shall notify the Company
of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder
shall be paid by the Company with reasonable promptness.


 


(4) Adjustments to Conversion Price


 


(a) Adjustment to Fixed Conversion Price. Except in the case of an event described
in either Section 4(c) or Section 4(d), if the Company shall, at any time or from time to time after the date hereof,
issue or sell, or in accordance with Section 4(b) is deemed to have issued or sold, any shares of Common Stock without consideration
or for consideration per share less than the Fixed Conversion Price in effect immediately prior to such issuance or sale (or deemed
issuance or sale), except for Excluded Securities, then immediately upon such issuance or sale (or deemed issuance or sale), the
Fixed Conversion Price in effect immediately prior to such issuance or sale (or deemed issuance or sale) shall be reduced (and
in no event increased) to a Fixed Conversion Price equal to the quotient obtained by dividing:


 


(i) the sum of (A) the
product obtained by multiplying the Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance
or sale) by the Fixed Conversion Price then in effect plus (B) the aggregate consideration, if any, received by
the Company upon such issuance or sale (or deemed issuance or sale); by the sum of (A) the
Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance or sale) plus (B) the aggregate
number of shares of Common Stock issued or sold (or deemed issued or sold) by the Company in such issuance or sale (or deemed
issuance or sale).


 






    	 	7	 



     


    

 


(b) Effect of Certain Events on Adjustment to Conversion Price. For purposes of determining the adjusted Conversion Price
under Section 4(a) hereof, the following shall be applicable:


 


(i) Issuance of Options. If the Company shall, at any time or from time to time after the Issuance Date, in any manner
grant or sell (whether directly or by assumption in a merger or otherwise) any Options, whether or not such Options or the right
to convert or exchange any Convertible Securities issuable upon the exercise of such Options are immediately exercisable, and the
price per share (determined as provided in this paragraph and in Section (4)(b)(v)) for which Common Stock is issuable upon the
exercise of such Options or upon the conversion or exchange of Convertible Securities issuable upon the exercise of such Options
is less than the Fixed Conversion Price in effect immediately prior to the time of the granting or sale of such Options, then the
total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the
total maximum amount of Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued as
of the date of granting or sale of such Options (and thereafter shall be deemed to be outstanding for purposes of adjusting the
Fixed Conversion Price under Section 4(a), at a price per share equal to the quotient obtained by dividing (A) the sum (which sum
shall constitute the applicable consideration received for purposes of Section 4(a) of (x) the total amount, if any, received or
receivable by the Company as consideration for the granting or sale of all such Options, plus (y) the minimum aggregate amount
of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options
which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Company
upon the issuance or sale of all such Convertible Securities and the conversion or exchange of all such Convertible Securities,
by (B) the total maximum number of shares of Common Stock issuable upon the exercise of all such Options or upon the conversion
or exchange of all Convertible Securities issuable upon the exercise of all such Options. Except as otherwise provided in Section
(4)(b)(iii), no further adjustment of the Conversion Price shall be made upon the actual issuance of Common Stock or of Convertible
Securities upon exercise of such Options or upon the actual issuance of Common Stock upon conversion or exchange of Convertible
Securities issuable upon exercise of such Options.


 


(ii) Issuance of Convertible Securities. If the Company shall, at any time or from time to time after the Issuance Date,
in any manner grant or sell (whether directly or by assumption in a merger or otherwise) any Convertible Securities, whether or
not the right to convert or exchange any such Convertible Securities is immediately exercisable, and the price per share (determined
as provided in this paragraph and in Section 4(b)(v)) for which Common Stock is issuable upon the conversion or exchange of such
Convertible Securities is less than the Fixed Conversion Price in effect immediately prior to the time of the granting or sale
of such Convertible Securities, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of
the total maximum amount of such Convertible Securities shall be deemed to have been issued as of the date of granting or sale
of such Convertible Securities (and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price
pursuant to Section 4(a)), at a price per share equal to the quotient obtained by dividing (A) the sum (which sum shall constitute
the applicable consideration received for purposes of Section 4(a)) of (x) the total amount, if any, received or receivable by
the Company as consideration for the granting or sale of such Convertible Securities, plus (y) the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the conversion or exchange of all such Convertible Securities, by
(B) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities.
Except as otherwise provided in Section (4)(b)(iii), (A) no further adjustment of the Conversion Price shall be made upon the actual
issuance of Common Stock upon conversion or exchange of such Convertible Securities and (B) no further adjustment of the Conversion
Price shall be made by reason of the issue or sale of Convertible Securities upon exercise of any Options to purchase any such
Convertible Securities for which adjustments of the Conversion Price have been made pursuant to the other provisions of this Section
(4)(b).


 






    	 	8	 



     


    

 


(iii) Change in Terms of Options or Convertible Securities. Upon any change in any of (A) the total amount received or
receivable by the Company as consideration for the granting or sale of any Options or Convertible Securities referred to in Section
(4)(b)(i) or Section (4)(b)(ii) hereof, (B) the minimum aggregate amount of additional consideration, if any, payable to the Company
upon the exercise of any Options or upon the issuance, conversion or exchange of any Convertible Securities referred to in Section
(4)(b)(i) or Section (4)(b)(ii) hereof, (C) the rate at which Convertible Securities referred to in Section (4)(b)(i) or Section
(4)(b)(ii) hereof are convertible into or exchangeable for Common Stock, or (D) the maximum number of shares of Common Stock issuable
in connection with any Options referred to in Section (4)(b)(i) hereof or any Convertible Securities referred to in Section (4)(b)(ii)
hereof, then (whether or not the original issuance or sale of such Options or Convertible Securities resulted in an adjustment
to the Fixed Conversion Price pursuant to this Section 4) the Fixed Conversion Price in effect at the time of such change shall
be adjusted or readjusted, as applicable, to the Fixed Conversion Price which would have been in effect at such time pursuant to
the provisions of this Section 4 had such Options or Convertible Securities still outstanding provided for such changed consideration,
conversion rate or maximum number of shares, as the case may be, at the time initially granted, issued or sold, but only if as
a result of such adjustment or readjustment the Fixed Conversion Price then in effect is reduced, and the number of shares of Common
Stock obtainable upon conversion of this Debenture will be proportionately adjusted or readjusted.


 


(iv) Treatment of Expired or Terminated Options or Convertible Securities. Upon the expiration or termination of any unexercised
Option (or portion thereof) or any unconverted or unexchanged Convertible Security (or portion thereof) for which any adjustment
(either upon its original issuance or upon a revision of its terms) was made pursuant to this Section 4 (including without limitation
upon the redemption or purchase for consideration of all or any portion of such Option or Convertible Security by the Company),
the Conversion Price then in effect hereunder shall forthwith be changed pursuant to the provisions of this Section 4 to the Fixed
Conversion Price which would have been in effect at the time of such expiration or termination had such unexercised Option (or
portion thereof) or unconverted or unexchanged Convertible Security (or portion thereof), to the extent outstanding immediately
prior to such expiration or termination, never been issued.


 






    	 	9	 



     


    

 


(v) Calculation of Consideration Received. If the Company shall, at any time or from time to time after the Issuance
Date, issue or sell, or is deemed to have issued or sold in accordance with Section (4)(b), any shares of Common Stock, Options
or Convertible Securities: (A) for cash, the consideration received therefor shall be deemed to be the net amount received by the
Company therefor; (B) for consideration other than cash, the amount of the consideration other than cash received by the Company
shall be the fair value of such consideration, except where such consideration consists of marketable securities, in which case
the amount of consideration received by the Company shall be the market price (as reflected on any securities exchange, quotation
system or association or similar pricing system covering such security) for such securities as of the end of business on the date
of receipt of such securities; (C) for no specifically allocated consideration in connection with an issuance or sale of other
securities of the Company, together comprising one integrated transaction, the amount of the consideration therefor shall be deemed
to be the fair value of such portion of the aggregate consideration received by the Company in such transaction as is attributable
to such shares of Common Stock, Options or Convertible Securities, as the case may be, issued in such transaction; or (D) to the
owners of the non-surviving entity in connection with any merger in which the Company is the surviving corporation, the amount
of consideration therefor shall be deemed to be the fair value of such portion of the net assets and business of the non-surviving
entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be, issued to such
owners. The net amount of any cash consideration and the fair value of any consideration other than cash or marketable securities
shall be determined in good faith by the Board of Directors of the Company, which shall be final and binding, absent manifest error.


 


(vi) Record Date. For purposes of any adjustment to the Fixed Conversion Price or the number of shared of Common Stock
issuable upon conversion of this Debenture in accordance with this Section 4, in case the Company shall take a record of the holders
of its Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock,
Options or Convertible Securities or (B) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such
record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription
or purchase, as the case may be.


 


(vii) Treasury Shares. The number of shares of Common Stock outstanding at any given time shall not include shares owned
or held by or for the account of the Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other
than the cancellation or retirement thereof or the transfer of such shares among the Company and its wholly-owned subsidiaries)
shall be considered an issue or sale of Common Stock for the purpose of this Section 4.


 


(c) Adjustment of Fixed Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time
after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its
outstanding shares of Common Stock into a greater number of shares, the Fixed Conversion Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of shares of Common Stock obtainable upon conversion of this Debenture
will be proportionately increased. If the Company at any time after the Issuance Date combines (by combination, reverse stock split
or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, any Fixed Conversion
Price in effect immediately prior to such combination will be proportionately increased and the number of shares of Common Stock

(d) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation
of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other
assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make
appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Debenture,
at the Holder's option, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other
assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock
been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions
on the convertibility of this Debenture) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion,
such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate
Event in such amounts as the Holder would have been entitled to receive had this Debenture initially been issued with conversion
rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate
with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the
Holder. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without
regard to any limitations on the conversion or redemption of this Debenture.


 


(e) Notification of Adjustment. Whenever the Conversion Price is adjusted pursuant to Section 4 hereof, the Company shall
promptly send the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 


(5) REISSUANCE OF THIS DEBENTURE.


 


(a) Transfer. If this Debenture is to be transferred, the Holder shall surrender this Debenture to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new Debenture (in accordance with Section 5(d)), registered
in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder (along
with any accrued and unpaid interest thereof) and, if less then the entire outstanding Principal is being transferred, a new Debenture
(in accordance with Section 5(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any
assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of Section 3(c)(iii) following
conversion or redemption of any portion of this Debenture, the outstanding Principal represented by this Debenture may be less
than the Principal stated on the face of this Debenture.

(b) Lost, Stolen or Mutilated Debenture. Upon receipt by the Company of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Debenture, and, in the case of loss, theft or destruction, of any indemnification
undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this
Debenture, the Company shall execute and deliver to the Holder a new Debenture (in accordance with Section 5(d)) representing the
outstanding Principal.


 


(c) Debenture Exchangeable for Different Denominations. This Debenture is exchangeable, upon the surrender hereof by
the Holder at the principal office of the Company, for a new Debenture or Debentures (in accordance with Section 5(d)) representing
in the aggregate the outstanding Principal of this Debenture, and each such new Debenture will represent such portion of such outstanding
Principal as is designated by the Holder at the time of such surrender.


 


(d) Issuance of New Debentures. Whenever the Company is required to issue a new Debenture pursuant to the terms of this
Debenture, such new Debenture (i) shall be of like tenor with this Debenture, (ii) shall represent, as indicated on the face of
such new Debenture, the Principal remaining outstanding (or in the case of a new Debenture being issued pursuant to Section 5(a)
or Section 5(c), the Principal designated by the Holder which, when added to the principal represented by the other new Debentures
issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Debenture immediately prior
to such issuance of new Debentures), (iii) shall have an issuance date, as indicated on the face of such new Debenture, which is
the same as the Issuance Date of this Debenture, (iv) shall have the same rights and conditions as this Debenture, and (v) shall
represent accrued and unpaid Interest from the Issuance Date.

for all fees, costs and expenses, including, without limitation, attorneys’ fees and expenses incurred by the Holder in any

prohibit or forgive the Company from paying all or any portion of the principal of or interest on this Debenture as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture,
and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants
that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder,
but will suffer and permit the execution of every such as though no such law has been enacted.


 


(14) Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day.


 


(15) THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT
