the Company may treat the Person in whose name this Debenture is duly registered on the Debenture Register as the owner hereof
for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Debenture is overdue, and
neither the Company nor any such agent shall be affected by notice to the contrary.


 


Section 4.          Conversion.


 




    	 	6	 



     


    

 


a)          Voluntary
Conversion. At any time after the Original Issue Date until this Debenture is no longer outstanding, this Debenture shall
be convertible, in whole or in part, into Ordinary Shares at the option of the Holder, at any time and from time to time (subject
to the conversion limitations set forth in Section 4(d) hereof). The Holder shall effect conversions by delivering to the Company
a Notice of Conversion, the form of which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying
therein the principal amount of this Debenture to be converted and the date on which such conversion shall be effected (such date,
the “Conversion Date”) and if required, in accordance with the provisions of the Purchase Agreement, delivering to
the Company an undertaking towards the NTIA substantially in the form that was attached to the Purchase Agreement as Exhibit B
or in any other form required by the NTIA (the “NTIA Undertaking”) duly executed by the Holder. If no Conversion Date
is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion is deemed delivered
hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee
or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall not be required
to physically surrender this Debenture to the Company unless the entire principal amount of this Debenture, has been so converted
in which case the Holder shall surrender this Debenture as promptly as is reasonably practicable after such conversion without
delaying the Company’s obligation to deliver the shares on the Share Delivery Date. Conversions hereunder shall have the
effect of lowering the outstanding principal amount of this Debenture in an amount equal to the applicable conversion. The Holder
and the Company shall maintain records showing the principal amount(s) converted and the date of such conversion(s). The Company
may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion. In
the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest
error. The Holder, and any assignee by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions
of this paragraph, following conversion of a portion of this Debenture, the unpaid and unconverted principal amount of this Debenture
may be less than the amount stated on the face hereof. 







 


b)          Conversion
Price. The conversion price in effect on any Conversion Date shall be equal to $0.50 per share, subject to adjustment
herein (the “Conversion Price”). In addition, on each Trigger Date, the Conversion Price shall be reduced, and
only reduced, to the lesser of (x) the then Conversion Price, as adjusted and taking into consideration any prior resets, or (y)
the average of the two lowest VWAPs during the 10 Trading Days immediately prior to each such Trigger Date (the “Reset
Conversion Price”, which shall thereafter be the new Conversion Price, subject to further adjustment hereunder, and each
such 10 Trading Day period shall be referred to herein as a “Measurement Period”). The Company shall notify
each Holder of the applicable adjustment to the Conversion Price as of such date (a “Trigger Date Adjustment Notice”). 
For purposes of clarification, whether or not the Company provides a Trigger Date Adjustment Notice pursuant to this Section 4(b),
Holder shall receive a number of Conversion Shares based upon the Conversion Price as adjusted pursuant to this Section, regardless
of whether a Holder accurately refers to such price in any Notice of Conversion. For clarity and avoidance of doubt, the Holder
is not subject to any trading restrictions during a Measurement Period. Notwithstanding
the foregoing, in no event shall the Reset Conversion Price be reduced pursuant to this Section 4(b) or Section 5(b) below to less
than $0.25 per share, subject to adjustment for reverse stock splits and the like (the “Minimum Conversion Price”)
and in no event shall the number of Conversion Shares issuable hereunder exceed the principal amount of this Debenture divided
by the Minimum Conversion Price.  For purposes of clarification, in no event shall the number of Conversion Shares issuable
pursuant to Conversion of this Debenture exceed [___________] shares, subject to adjustment for reverse stock splits and the like.


 





c)             Mechanics
of Conversion.




 




    	 	7	 



     


    

 


i.            Conversion
Shares Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion hereunder shall
be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Debenture to be converted by (y)
the Conversion Price.


 


ii.         Delivery
of Conversion Shares Upon Conversion. Not later than the earlier of (i) three (3) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period (as defined below) after
each Conversion Date (the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the
Holder the Conversion Shares which, on or after the earlier of (i) the six month anniversary of the Original Issue Date and (ii)
the Effectiveness Date, shall be free of restrictive legends and trading restrictions representing the number of Conversion Shares
being acquired upon the conversion of this Debenture. On or after the earlier of (i) the six month anniversary of the Original
Issue Date and (ii) the Effectiveness Date, the Company shall deliver any Conversion Shares required to be delivered by the Company
under this Section 4(c) electronically through the Depository Trust Company or another established clearing corporation performing
similar functions. 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 Ordinary Shares as in effect on
the date of delivery of the Notice of Conversion.


 


iii.         Failure
to Deliver Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares are not delivered to or as
directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the Company
at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which event the Company shall promptly
return to the Holder any original Debenture delivered to the Company and the Holder shall promptly return to the Company the Conversion
Shares issued to such Holder pursuant to the rescinded Conversion Notice.


 




    	 	8	 



     


    

 


iv.         Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion
of this Debenture in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by
the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against
any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach
or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law
by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the
Company to the Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery
shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event the Holder
of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse conversion
based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of law,
agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining conversion
of all or part of this Debenture shall have been sought and obtained, and the Company posts a surety bond for the benefit of the
Holder in the amount of 150% of the outstanding principal amount of this Debenture, which is subject to the injunction, which bond
shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall
be payable to the Holder to the extent it obtains judgment. In the absence of such injunction, the Company shall issue Conversion
Shares or, if applicable, cash, upon a properly noticed conversion. If the Company fails for any reason to deliver to the Holder
such Conversion Shares pursuant to Section 4(c)(ii) by the Share Delivery Date, the Company shall pay to the Holder, in cash, as
liquidated damages and not as a penalty, for each $1,000 of principal amount being converted, $10 per Trading Day (increasing to
$20 per Trading Day on the fifth (5th) Trading Day after such liquidated damages begin to accrue) for each Trading Day
after such Share Delivery Date until such Conversion Shares are delivered or Holder rescinds such conversion. Nothing herein shall
limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 8 hereof for the Company’s
failure to deliver Conversion Shares within the period specified herein and the Holder shall have the right to pursue all remedies
available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive
relief. 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.


 




    	 	9	 



     


    

 


v.           Compensation
for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the
Holder, if the Company fails for any reason to deliver to the Holder such Conversion Shares by the Share Delivery Date pursuant
to Section 4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open
market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, Ordinary Shares to deliver in satisfaction
of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such
Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in addition to any other
remedies available to or elected by the Holder) the amount, if any, by which (x) the Holder’s total purchase price (including
any brokerage commissions) for the Ordinary Shares so purchased exceeds (y) the product of (1) the aggregate number of Ordinary
Shares that the Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the
sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of
the Holder, either reissue (if surrendered) this Debenture in a principal amount equal to the principal amount of the attempted
conversion (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number of Ordinary Shares that
would have been issued if the Company had timely complied with its delivery requirements under Section 4(c)(ii). For example, if
the Holder purchases Ordinary Shares having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion
of this Debenture with respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving
rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall
be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the
Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit
a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Conversion
Shares upon conversion of this Debenture as required pursuant to the terms hereof.


 




    	 	10	 



     


    

 


vi.         Reservation
of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its authorized
and unissued Ordinary Shares for the sole purpose of issuance upon conversion of this Debenture, free from preemptive rights or
any other actual contingent purchase rights of Persons other than the Holder (and the other holders of the Debentures), not less
than such aggregate number of Ordinary Shares as shall be issuable upon the conversion of the then outstanding principal amount
of this Debenture. The Company covenants that all Ordinary Shares that shall be so issuable shall, upon issue, be duly authorized,
validly issued, fully paid and nonassessable.


 


vii.         Fractional
Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Debenture.
As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, 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 Conversion Price or round up to the next whole share.


 


viii.         Transfer
Taxes and Expenses. The issuance of Conversion Shares on conversion of this Debenture shall be made without charge to the Holder
hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion Shares,
provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance
and delivery of any such Conversion Shares upon conversion in a name other than that of the Holder of this Debenture so converted
and the Company shall not be required to issue or deliver such Conversion Shares unless or until the Person or Persons requesting
the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice
of Conversion and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions)
required for same-day electronic delivery of the Conversion Shares.


 




    	 	11	 



     


    

 


d)
            Holder’s Conversion Limitations. The Company
shall not effect any conversion of this Debenture, and a Holder shall not have the right to convert any portion of this Debenture,
to the extent that after giving effect to the conversion set forth on the applicable Notice of Conversion, the Holder (together
with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s
Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below).  For purposes of the foregoing sentence, the number of Ordinary Shares beneficially owned
by the Holder and its Affiliates and Attribution Parties shall include the number of Ordinary Shares issuable upon conversion
of this Debenture with respect to which such determination is being made, but shall exclude the number of Ordinary Shares which
are issuable upon (i) conversion of the remaining, unconverted principal amount of this Debenture beneficially owned by the Holder
or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any
other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein
(including, without limitation, any other Debentures or the Warrants) beneficially owned by the Holder or any of its Affiliates
or Attribution Parties.  Except as set forth in the preceding sentence, for purposes of this Section 4(d), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
To the extent that the limitation contained in this Section 4(d) applies, the determination of whether this Debenture is convertible
(in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which principal
amount of this Debenture is convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion
shall be deemed to be the Holder’s determination of whether this Debenture may be converted (in relation to other securities
owned by the Holder together with any Affiliates or Attribution Parties) and which principal amount of this Debenture is convertible,
in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, the Holder will be deemed
to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions
set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4(d), in determining the
number of outstanding Ordinary Shares, the Holder may rely on the number of outstanding Ordinary Shares as stated in the most
recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case
may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s
transfer agent setting forth the number of Ordinary Shares outstanding.  Upon the written or oral request of a Holder, the
Company shall within two Trading Days confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. 
In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of
securities of the Company, including this Debenture, by the Holder or its Affiliates since the date as of which such number of
outstanding Ordinary Shares were reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number
of Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares issuable upon conversion of
this Debenture held by the Holder. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 4(d), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of
Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares upon conversion of this Debenture
held by the Holder and the Beneficial Ownership Limitation provisions of this Section 4(d) shall continue to apply. Any increase
in the Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered to the
Company.  The Beneficial Ownership Limitation
provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms
of this Section 4(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect
to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Debenture.

Section 5.          Certain
Adjustments.


 


a)             Stock
Dividends and Stock Splits. If the Company, at any time while this Debenture is outstanding: (i) pays a stock dividend or otherwise
makes a distribution or distributions payable in Ordinary Shares on Ordinary Shares or any Common Stock Equivalents (which, for
avoidance of doubt, shall not include any Ordinary Shares issued by the Company upon conversion of the Debentures), (ii) subdivides
outstanding Ordinary Shares into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding
Ordinary Shares into a smaller number of shares or (iv) issues, in the event of a reclassification of the Ordinary Shares, any
shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall
be the number of Ordinary Shares (excluding any treasury shares of the Company) outstanding immediately before such event, and
of which the denominator shall be the number of Ordinary Shares outstanding immediately after such event. Any adjustment made pursuant
to this Section 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.


 




    	 	13	 



     


    

 


b)             Subsequent
Equity Sales. If, at any time while this Debenture is outstanding until the later of (i) the Second Closing Date and (ii) the
18 month anniversary of the effective date of the Resale Registration Statement (as defined in the Purchase Agreement), the Company
or any Subsidiary, as applicable, sells or grants any option to purchase or sells or grants any right to reprice, or otherwise
disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Ordinary Shares or Common
Stock Equivalents entitling any Person to acquire Ordinary Shares at an effective price per share that is lower than the then Conversion
Price (such lower price, the “Base Conversion Price” and such issuances, collectively, a “Dilutive
Issuance”) (if the holder of the Ordinary Shares or Common Stock Equivalents so issued shall at any time, whether by
operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due
to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive Ordinary Shares
at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less
than the Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base
Conversion Price; provided, however, in no event shall the Conversion Price be reduced pursuant to this Section 5(b)
to less than $0.25, subject to adjustment for reverse and forward stock splits and the like. Such adjustment shall be made
whenever such Ordinary Shares or Common Stock Equivalents are issued. Notwithstanding the foregoing, no adjustment will be made
under this Section 5(b) in respect of an Exempt Issuance. If the Company enters into a Variable Rate Transaction, despite the prohibition
set forth in the Purchase Agreement, the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the
lowest possible conversion price at which such securities may be converted or exercised. The Company shall notify the Holder in
writing, no later than the Trading Day following the issuance of any Ordinary Shares or Common Stock Equivalents subject to this
Section 5(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and
other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or
not the Company provides a Dilutive Issuance Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance,
the Holder is entitled to receive a number of Conversion Shares based upon the Base Conversion Price on or after the date of such
Dilutive Issuance, regardless of whether the Holder accurately refers to the Base Conversion Price in the Notice of Conversion.


 


c)             Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 5(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of Ordinary Shares (the “Purchase Rights”), then the Holder will be entitled to acquire,
upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder
had held the number of Ordinary Shares acquirable upon complete conversion of this Debenture (without regard to any limitations
on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a
record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which
the record holders of Ordinary Shares are to be determined for the grant, issue or sale of such Purchase Rights (provided, however,
to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the
Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or
beneficial ownership of such Ordinary Shares as a result of such Purchase Right to such extent) and such Purchase Right to such
extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder
exceeding the Beneficial Ownership Limitation).


 




    	 	14	 



     


    

 


d)             Pro
Rata Distributions. During such time as this Debenture is outstanding, if the Company shall declare or make any dividend or
other distribution of its assets (or rights to acquire its assets) to all holders of Ordinary Shares (and not to the Holder), 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 Debenture, 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 Ordinary Shares acquirable upon complete conversion of this Debenture (without regard to any limitations
on conversion 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 Ordinary Shares
are to be determined for the participation in such Distribution (provided, however, 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 Ordinary
Shares 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).


 




    	 	15	 



     


    

 


e)
            Fundamental Transaction. If, at any time while
this Debenture is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any
merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any
sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one
or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether
by the Company or another Person) is completed pursuant to which holders of Ordinary Shares are permitted to sell, tender or
exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Ordinary Shares, (iv) the Company, directly or indirectly, in one or more related transactions effects any
reclassification, reorganization or recapitalization of the Ordinary Shares or any compulsory share exchange pursuant to
which the Ordinary Shares are effectively converted into or exchanged for other securities, cash or property, or (v) the
Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other
business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement)
with another Person whereby such other Person acquires more than 50% of the outstanding Ordinary Shares (not including any
Ordinary Shares held by the other Person or other Persons making or party to, or associated or affiliated with the other
Persons making or party to, such stock or share purchase agreement or other business combination) (each a
“Fundamental Transaction”), then, upon any subsequent conversion of this Debenture, the Holder shall have
the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the
occurrence of such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion of this
Debenture), the number of Ordinary Shares of the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of
such Fundamental Transaction by a holder of the number of Ordinary Shares for which this Debenture is convertible immediately
prior to such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion of this Debenture).
For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to
such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of
Ordinary Shares in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate
Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate
Consideration. If holders of Ordinary Shares are given any choice as to the securities, cash or property to be received in a
Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any conversion of this Debenture following such Fundamental Transaction. The Company shall cause any successor entity in a
Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in
writing all of the obligations of the Company under this Debenture and the other Transaction Documents (as defined in the
Purchase Agreement) in accordance with the provisions of this Section 5(e) pursuant to written agreements in form and
substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such
Fundamental Transaction and shall, at the option of the holder of this Debenture, deliver to the Holder in exchange for this
Debenture a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to
this Debenture which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its
parent entity) equivalent to the Ordinary Shares acquirable and receivable upon conversion of this Debenture (without regard
to any limitations on the conversion of this Debenture) prior to such Fundamental Transaction, and with a conversion price
which applies the conversion price hereunder to such shares of capital stock (but taking into account the relative value of
the Ordinary Shares pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of
shares of capital stock and such conversion price being for the purpose of protecting the economic value of this
Debenture immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in
form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed
to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Debenture
and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and
may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Debenture
and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company
herein.

f)         Calculations.
All calculations under this Section 5 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 5, the number of Ordinary Shares deemed to be issued and outstanding as of a given date shall be the
sum of the number of Ordinary Shares (excluding any treasury shares of the Company) issued and outstanding.


 


g)        Notice
to the Holder.


 


i.            Adjustment
to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall
promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 


ii.         Notice
to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the Ordinary Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Ordinary Shares,
(C) the Company shall authorize the granting to all holders of the Ordinary Shares of 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 Ordinary Shares, 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 Ordinary
Shares are 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 filed at each office
or agency maintained for the purpose of conversion of this Debenture, and shall cause to be delivered to the Holder at its last
address as it shall appear upon the Debenture Register, at least fifteen (15) 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 Ordinary Shares 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 Ordinary Shares of record shall be entitled to exchange their Ordinary Shares 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 hereunder 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 Report on Form 6-K. The Holder shall remain entitled to convert this Debenture
during the 15-day period commencing on the date of such notice through the effective date of the event triggering such notice except
as may otherwise be expressly set forth herein.


 




    	 	17	 



     


    

 


Section 6.          Forced
Conversion. Notwithstanding anything herein to the contrary, if after the Effectiveness Date (as such term is defined in the
Registration Rights Agreement), the VWAP for each of any 30 consecutive Trading Days, which period shall have commenced only after
the Effectiveness Date (such period the “Threshold Period”), exceeds 300% of the Conversion Price then in effect,
the Company may, within 1 Trading Day after the end of any such Threshold Period, deliver a written notice to the Holder (a “Forced
Conversion Notice” and the date such notice is delivered to the Holder, the “Forced Conversion Notice Date”)
to cause the Holder to convert all or part of the then outstanding principal amount of this Debenture plus, if so specified in
the Forced Conversion Notice, liquidated damages and other amounts owing to the Holder under this Debenture, it being agreed that
the “Conversion Date” for purposes of Section 4 shall be deemed to occur on the third Trading Day following the Forced
Conversion Notice Date (such third Trading Day, the “Forced Conversion Date”). The Company may not deliver
a Forced Conversion Notice, and any Forced Conversion Notice delivered by the Company shall not be effective, unless all of the
Equity Conditions are met (unless waived in writing by the Holder) on each Trading Day occurring during the applicable Threshold
Period through and including the later of the Forced Conversion Date and the Trading Day after the date such Conversion Shares
pursuant to such conversion are delivered to the Holder. Any Forced Conversion shall be applied ratably to all Holders based on
their initial purchases of Debentures pursuant to the Purchase Agreement, provided that any voluntary conversions by a Holder
shall be applied against the Holder’s pro rata allocation, thereby decreasing the aggregate amount forcibly converted hereunder.


 


Section 7.          Negative
Covenants. As long as any portion of this Debenture remains outstanding, unless the holders of at least 67% in principal amount
of the then outstanding Debentures shall have otherwise given prior written consent, the Company shall not, and shall not permit
any of the Subsidiaries to, directly or indirectly:


 


a)          enter
into, create, incur, assume, guarantee or suffer to exist any indebtedness convertible into Ordinary Shares with a conversion feature
that permits a conversion price of less than $0.25 per Ordinary Share, subject to adjustment for reverse and forward stock splits
and the like;


 




    	 	18	 



     


    

 


b)          amend
its charter documents, including, without limitation, its certificate of incorporation and bylaws, in any manner that materially
and adversely affects any rights of the Holder;


 


c)          repay,
repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of shares of its Common
Stock or Common Stock Equivalents other than as to (i) the Conversion Shares or Warrant Shares as permitted or required under the
Transaction Documents and (ii) repurchases of Common Stock or Common Stock Equivalents of departing officers and directors of the
Company, provided that such repurchases shall not exceed an aggregate of $10,000 for all officers and directors during the term
of this Debenture; or


 


d)          enter
into any agreement with respect to any of the foregoing.


 


Section 8.          Events
of Default.


 


a)          “Event
of Default” means, wherever used herein, any of the following events (whatever the reason for such event and whether
such event shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any
court, or any order, rule or regulation of any administrative or governmental body):


 


i.            any
default in the payment of (A) the principal amount of any Debenture or (B) liquidated damages and other amounts owing to a Holder
on any Debenture, as and when the same shall become due and payable (whether on a Conversion Date or the Maturity Date or by acceleration
or otherwise) which default is not cured within 10 Trading Days;


 


ii.         the
Company shall fail to observe or perform any other covenant or agreement contained in the Debentures (other than a breach by the
Company of its obligations to deliver Ordinary Shares to the Holder upon conversion, which breach is addressed in clause (ix) below)
or in any Transaction Document, which failure is not cured, if possible to cure, within the earlier to occur of (A) 10 Trading
Days after notice of such failure sent by the Holder or by any other Holder to the Company and (B) 10 Trading Days after the Company
has become or should have become aware of such failure;


 


iii.         a
default or event of default (subject to any grace or cure period provided in the applicable agreement, document or instrument)
shall occur under (A) any of the Transaction Documents or (B) any other material agreement, lease, document or instrument to which
the Company or any Subsidiary is obligated (and not covered by clause (vi) below);


 




    	 	19	 



     


    

 


iv.         any
representation or warranty made in this Debenture, any other Transaction Documents, any written statement pursuant hereto or thereto
or any other report, financial statement or certificate made or delivered to the Holder or any other Holder shall be untrue or
incorrect in any material respect as of the date when made or deemed made;


 


v.           the
Company or any Significant Subsidiary (as such term is defined in Rule 1-02(w) of Regulation S-X) shall be subject to a Bankruptcy
Event;


 


vi.         the
Company or any Subsidiary shall default on any of its obligations under any mortgage, credit agreement or other facility, indenture
agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured or evidenced,
any indebtedness for borrowed money or money due under any long term leasing or factoring arrangement that (a) involves an obligation
greater than $15,000, whether such indebtedness now exists or shall hereafter be created, and (b) results in such indebtedness
becoming or being declared due and payable prior to the date on which it would otherwise become due and payable;


 


vii.         the
Common Stock shall not be eligible for listing or quotation for trading on a Trading Market and shall not be eligible to resume
listing or quotation for trading thereon within five Trading Days;


 


viii.         the
Company shall be a party to any Change of Control Transaction or Fundamental Transaction or shall agree to sell or dispose of all
or in excess of 33% of its assets in one transaction or a series of related transactions (whether or not such sale would constitute
a Change of Control Transaction);


 


ix.         the
Company shall fail for any reason to deliver Conversion Shares to a Holder prior to the fifth Trading Day after a Conversion Date
pursuant to Section 4(c) or the Company shall provide at any time notice to the Holder, including by way of public announcement,
of the Company’s intention to not honor requests for conversions of any Debentures in accordance with the terms hereof;


 


x.         the
electronic transfer by the Company of shares of Common Stock through the Depository Trust Company or another established clearing
corporation is no longer available or is subject to a “chill”;


 


xi.            the
Company shall fail to meeting the current public information requirements under Rule 144; or


 




    	 	20	 



     


    

 


xii.         any
monetary judgment, writ or similar final process shall be entered or filed against the Company, any subsidiary or any of their
respective property or other assets for more than $100,000, and such judgment, writ or similar final process shall remain unvacated,
unbonded or unstayed for a period of 45 calendar days.


 


b)          Remedies
Upon Event of Default. If any Event of Default occurs, the outstanding principal amount of this Debenture, liquidated damages
and other amounts owing in respect thereof through the date of acceleration, shall become, at the Holder’s election, immediately
due and payable in cash at the Mandatory Default Amount. Commencing 5 days after the occurrence of any Event of Default that results
in the eventual acceleration of this Debenture, the interest rate on this Debenture shall accrue at an interest rate equal to
the lesser of 18% per annum or the maximum rate permitted under applicable law. Upon the payment in full of the Mandatory Default
Amount, the Holder shall promptly surrender this Debenture to or as directed by the Company. In connection with such acceleration
described herein, the Holder need not provide, and the Company hereby waives, any presentment, demand, protest or other notice
of any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies
hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Holder
at any time prior to payment hereunder and the Holder shall have all rights as a holder of the Debenture until such time, if any,
as the Holder receives full payment pursuant to this Section 8(b). No such rescission or annulment shall affect any subsequent
Event of Default or impair any right consequent thereon.


 


Section 9.          Miscellaneous.


 


a)         Notices.
Any and all notices or other communications or deliveries to be provided by the Holder hereunder, including, without limitation,
any Notice of Conversion, shall be in writing and delivered personally, by facsimile, by email attachment, or sent by a nationally
recognized overnight courier service, addressed to the Company, at the address set forth above, or such other facsimile number,
email address, or address as the Company may specify for such purposes by notice to the Holder delivered in accordance with this
Section 9(a).  Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be
in writing and delivered personally, by facsimile, by email attachment, or sent by a nationally recognized overnight courier service
addressed to each Holder at the facsimile number, email address or address of the Holder appearing on the books of the Company,

    	 	21	 



     


    

 


b)         Absolute
Obligation. Except as expressly provided herein, no provision of this Debenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and liquidated damages, as applicable, on this Debenture
at the time, place, and rate, and in the coin or currency, herein prescribed. This Debenture is a direct debt obligation of the
Company. This Debenture ranks pari passu with all other Debentures now or hereafter issued under the terms set forth
herein.         


 


c)         Lost
or Mutilated Debenture. If this Debenture shall be mutilated, lost, stolen or destroyed, the Company shall execute and deliver,
in exchange and substitution for and upon cancellation of a mutilated Debenture, or in lieu of or in substitution for a lost, stolen
or destroyed Debenture, a new Debenture for the principal amount of this Debenture so mutilated, lost, stolen or destroyed, but
only upon receipt of evidence of such loss, theft or destruction of such Debenture, and of the ownership hereof, reasonably satisfactory
to the Company.


 


d)         Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Debenture shall be governed
by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense
of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective
Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for
such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence
of delivery) to such party at the address in effect for notices to it under this Debenture and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any
way any right to serve process in any other manner permitted by applicable law. Each party hereto hereby irrevocably waives, to
the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating
to this Debenture or the transactions contemplated hereby. If any party shall commence an action or proceeding to enforce any
provisions of this Debenture, then the prevailing party in such action or proceeding shall be reimbursed by the other party for
its attorneys fees and other costs and expenses incurred in the investigation, preparation and prosecution of such action or proceeding.


 




    	 	22	 



     


    

 


e)         Waiver.
Any waiver by the Company or the Holder of a breach of any provision of this Debenture shall not operate as or be construed to
be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture. The failure of the
Company or the Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall not be considered
a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this
Debenture on any other occasion. Any waiver by the Company or the Holder must be in writing.


 


f)         Severability.
If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in effect,
and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons
and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable
law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of
interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall not at
any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury
law or other law which would 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 Debenture, 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 impede 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.


 


g)         Remedies,
Characterizations, Other Obligations, Breaches and Injunctive Relief.  The remedies provided in this Debenture shall be
cumulative and in addition to all other remedies available under this Debenture and any of the other Transaction Documents at law

right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Debenture. 
The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly
provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation
thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any
other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder
will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore
agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available
remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic
loss and without any bond or other security being required. The Company shall provide all information and documentation to the
Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions
of this Debenture.

shall be made on the next succeeding Business Day.


 


i)         Headings.
The headings contained herein are for convenience only, do not constitute a part of this Debenture and shall not be deemed to limit
or affect any of the provisions hereof.


 


Section 10. Disclosure.
Upon receipt or delivery by the Company of any notice in accordance with the terms of this Debenture, unless the Company has in
good faith determined that the matters relating to such notice do not constitute material, nonpublic information relating to the
Company or its Subsidiaries, the Company shall within one (1) Business Day after such receipt or delivery publicly disclose such
material, nonpublic information on a Report on Form 6-K or otherwise. In the event that the Company believes that a notice contains
material, non-public information relating to the Company or its Subsidiaries, the Company so shall indicate to the Holder contemporaneously
with delivery of such notice, and in the absence of any such indication, the Holder shall be allowed to presume that all matters
relating to such notice do not constitute material, nonpublic information relating to the Company or its Subsidiaries.
