Section 3.02     Remedies.
Upon the occurrence of an Event of Default that is not timely cured within an applicable cure period hereunder (or, as to clause
(ix) thereunder, on the tenth (10th) Trading Day following notice from the Holder if the Company is unable to provide
an explanation satisfactory to the Holder), the interest on this Debenture shall immediately accrue at an interest rate equal to
the lesser of (i) twenty-four percent (24%) per annum or (ii) the maximum interest rate allowable by law, and, in addition to all
other rights or remedies the Holder may have, at law or in equity, the Holder may, in its sole discretion, accelerate full repayment
of all principal amounts outstanding hereunder, together with accrued interest thereon, together with all attorneys’ fees,
paralegals’ fees and costs and expenses incurred by the Holder in collecting or enforcing payment hereof (whether such fees,
costs or expenses are incurred in negotiations, all trial and appellate levels, administrative proceedings, bankruptcy proceedings
or otherwise), and together with all other sums due by the Company hereunder and under the Transaction Documents, all without any
relief whatsoever from any valuation or appraisement laws, and payment thereof may be enforced and recovered in whole or in part
at any time by one or more of the remedies provided to the Holder at law, in equity, or under this Debenture or any of the other
Transaction Documents. In connection with the Holder’s rights hereunder upon an Event of Default, 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 enforce
any and all of its rights and remedies hereunder and all other remedies available to it in equity or under applicable law.


 


ARTICLE IV


 


Section 4.01     Usury
Savings Clause. Notwithstanding any provision in this Debenture or the other Transaction Documents to the contrary, the total
liability for payments of interest and payments in the nature of interest, including, without limitation, all charges, fees, exactions,
or other sums which may at any time be deemed to be interest, shall not exceed the limit imposed by the usury laws of the jurisdiction
governing this Debenture or any other applicable law. In the event the total liability of payments of interest and payments in
the nature of interest, including, without limitation, all charges, fees, exactions or other sums which may at any time be deemed
to be interest, shall, for any reason whatsoever, result in an effective rate of interest, which for any month or other interest
payment period exceeds the limit imposed by the usury laws of the jurisdiction governing this Debenture, all sums in excess of
those lawfully collectible as interest for the period in question shall, without further agreement or notice by, between, or to
any party hereto, be applied to the reduction of the outstanding principal balance due hereunder immediately upon receipt of such
sums by the Holder hereof, with the same force and effect as though the Company had specifically designated such excess sums to
be so applied to the reduction of the principal balance then outstanding, and the Holder hereof had agreed to accept such sums
as a penalty-free payment of principal; provided, however, that the Holder may, at any time and from time to time, elect, by notice
in writing to the Company, to waive, reduce, or limit the collection of any sums in excess of those lawfully collectible as interest,
rather than accept such sums as a prepayment of the principal balance then outstanding. It is the intention of the parties that
the Company does not intend or expect to pay, nor does the Holder intend or expect to charge or collect any interest under this
Debenture greater than the highest non-usurious rate of interest which may be charged under applicable law.

ARTICLE V


 


Section 5.01     No
Exemption. The Company hereby waives and releases all benefit that might accrue to the Company by virtue of any present or
future laws exempting any property that may serve as security for this Debenture, or any other property, real or personal, or any
part of the proceeds arising from any sale of any such property, from attachment, levy, or sale under execution, exemption from
civil process, or extension of time for payment; and the Company agrees that any property that may be levied upon pursuant to a

Section 5.02     Exercise
of Remedies. The remedies of the Holder as provided herein and in any of the other Transaction Documents shall be cumulative
and concurrent and may be pursued singly, successively or together, at the sole discretion of the Holder, and may be exercised

as a waiver or release thereof.


 


Section 5.03     Waivers.
The Company and all others who are, or may become liable for the payment hereof: (i) severally waive presentment for payment, demand,
notice of nonpayment or dishonor, protest and notice of protest of this Debenture or any other Transaction Documents, and all other
notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Debenture and
the other Transaction Documents, except as specifically provided in this Debenture or any other Transaction Document; (ii) expressly

against the Company or any other person or party to become liable hereunder or against any collateral that may secure this Debenture
in order to enforce the payment of this Debenture; and (iv) expressly agree that, notwithstanding the occurrence of any of the
foregoing (except the express written release by the Holder of any such person), the undersigned shall be and remain, directly
and primarily liable for all sums due under this Debenture.


 


Section 5.04      No
Waiver. Holder shall not be deemed, by any act of omission or commission, to have waived any of its rights or remedies hereunder
unless such waiver is in writing and signed by Holder, and then only to the extent specifically set forth in the writing. A waiver
on one event shall not be construed as continuing or as a bar to or waiver of any right or remedy to a subsequent event.

    	 	7	 



     


    

 


(1)       Voluntary
Conversion. At any time while this Debenture is outstanding on or after the Closing Date, at the sole option of the Holder
upon the occurrence of an Event of Default, the Holder may convert all or any portion of the outstanding principal, accrued and
unpaid interest, and any other sums due and payable hereunder or under any of the other Transaction Documents (such total amount,
the “Conversion Amount”) into shares of Common Stock of the Company (the “Conversion Shares”)
in an amount of shares equal to: (i) the Conversion Amount (the numerator); divided by (ii) eighty-five percent (85%) of
the lowest of the volume weighted average price of the Company’s Common Stock during the five (5) trading days immediately
prior to the Conversion Date (as defined below), as indicated in the conversion notice (in the form attached hereto as Exhibit
“A” the “Conversion Notice”) (the denominator) (the “Conversion Price”). The
Holder shall submit a Conversion Notice indicating the amount of the Debenture being converted and the number of Conversion Shares
issuable upon such conversion, and where the Conversion Shares should be delivered.


 


(2)       The
Holder’s Conversion Limitations. The Company shall not affect any conversion of this Debenture, and the 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 Conversion Notice submitted by the Holder, the Holder (together with the Holder’s affiliates (as defined herein) and
any Persons acting as a group together with the Holder or any of the Holder’s affiliates) would beneficially own in excess
of the Beneficial Ownership Limitation (as defined herein). To ensure compliance with this restriction, prior to delivery of any
Conversion Notice, the Holder shall have the right to request that the Company provide to the Holder a written statement of the
percentage ownership of the Company’s Common Stock that would by beneficially owned by the Holder and its affiliates in the
Company if the Holder converted such portion of this Debenture then intended to be converted by Holder. The Company shall, within
three (3) business days of such request, provide Holder with the requested information in a written statement, and the Holder shall
be entitled to rely on such written statement from the Company in issuing its Conversion Notice and ensuring that its ownership
of the Company’s Common Stock is not in excess of the Beneficial Ownership Limitation. The restriction described in this
Section may be waived by Holder, in whole or in part, upon notice from the Holder to the Company. For purposes of this Debenture,
the “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock issuable upon conversion of this Debenture. The limitations contained
in this Section shall apply to any successor holder of this Debenture. For purposes of this Debenture, “Person”
means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization
or a government or any department or agency thereof.


 


(3)      Mechanics
of Conversion.The conversion of this Debenture shall be conducted in the following manner:


 


(a)       Holder’s
Delivery Requirements. To convert this Debenture into shares of Common Stock on any date set forth in the Conversion Notice
by the Holder (the “Conversion Date”), the Holder shall transmit by facsimile or electronic mail (or otherwise
deliver) a copy of the fully executed Conversion Notice to the Company (or, under certain circumstances as set forth below, by
delivery of the Conversion Notice to the Company’s transfer agent).


 




    	 	8	 



     


    

 


(b)       Company’s
Response. Upon receipt by the Company of a copy of a Conversion Notice, the Company shall as soon as practicable, but in no
event later than three (3) Business Days after receipt of such Conversion Notice, send, via facsimile or electronic mail (or otherwise
deliver) a confirmation of receipt of such Conversion Notice (the “Conversion Confirmation”) to the Holder indicating
that the Company will process such Conversion Notice in accordance with the terms herein. In the event the Company fails to issue
its Conversion Confirmation within said three (3) Business Day time period, the Holder shall have the absolute and irrevocable
right and authority to deliver the fully executed Conversion Notice to the Company’s transfer agent, and pursuant to the
terms of the Purchase Agreement, the Company’s transfer agent shall issue the applicable Conversion Shares to Holder as hereby
provided. Within five (5) Business Days after the date of the Conversion Confirmation (or the date of the Conversion Notice, if
the Company fails to issue the Conversion Confirmation), provided that the Company’s transfer agent is participating in the
Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, the
Company shall cause the transfer agent to (or, if for any reason the Company fails to instruct or cause its transfer agent to so
act, then pursuant to the Purchase Agreement, the Holder may request and require the Company’s transfer agent to) electronically
transmit the applicable Conversion Shares to which the Holder shall be entitled by crediting the account of the Holder’s
prime broker with DTC through its Deposit Withdrawal Agent Commission (“DWAC”) system, and provide proof satisfactory
to the Holder of such delivery. In the event that the Company’s transfer agent is not participating in the DTC FAST program
and is not otherwise DWAC eligible (or in the event the Holder otherwise requests), within five (5) Business Days after the date
of the Conversion Confirmation (or the date of the Conversion Notice, if the Company fails to issue the Conversion Confirmation),
the Company shall instruct and cause its transfer agent to (or, if for any reason the Company fails to instruct or cause its transfer
agent to so act, then pursuant to the Purchase Agreement, the Holder may request and require the Company’s transfer agent
to) issue and surrender to a nationally recognized overnight courier for delivery to the address specified in the Conversion Notice,
a certificate, registered in the name of the Holder or its nominee, for the number of Conversion Shares to which the Holder shall
be entitled. 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, plus all accrued and unpaid interest thereon and other sums due hereunder,
has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Debenture
in an amount equal to the applicable Conversion Amount. The Holder and the Company shall maintain records showing the principal
amount(s) converted and the date of such conversion(s). 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.


 


(c)       Record
Holder. The Person(s) 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(s) of such shares of Common Stock as of the Conversion Date.


 


(d)       Failure
to Deliver Certificates. If in the case of any Conversion Notice, the certificate or certificates are not delivered to or as
directed by the Holder by the date required hereby, the Holder shall be entitled to elect by written notice to the Company at any
time on or before its receipt of such certificate or certificates, to rescind such Conversion Notice, 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 Common Stock certificates representing the principal amount of this Debenture unsuccessfully tendered for conversion
to the Company.

(e)       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 entity 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 or entity of any obligation to the Company or any violation or alleged
violation of law by the Holder or any other person or entity, 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 and accrued
but unpaid interest thereon in accordance with the terms of this Debenture, 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 being converted, 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 such Holder to the extent it obtains judgment. In the absence of such injunction, the Company shall issue Conversion
Shares upon a properly noticed conversion. If the Company fails for any reason to deliver to the Holder such certificate or certificates
representing Conversion Shares pursuant to timing and delivery requirements of this Debenture, the Company shall pay to such Holder,
in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount being converted, $1.00 per day for each
day after the date by which such certificates should have been delivered until such certificates are delivered. Nothing herein
shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to this Debenture or any agreement
securing the indebtedness under this Debenture for the Company’s failure to deliver Conversion Shares within the period specified
herein and such 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. Nothing herein shall prevent the
Holder from having the Conversion Shares issued directly by the Company’s transfer agent in accordance with the Purchase
Agreement, in the event for any reason the Company fails to issue or deliver, or cause its transfer agent to issue and deliver,
the Conversion Shares to the Holder upon exercise of Holder’s conversion rights hereunder.


 


(f)       Transfer
Taxes. The issuance of certificates for shares of the Common Stock on conversion of this Debenture shall be made without charge
to the Holder hereof for any documentary stamp or similar taxes, or any other issuance or transfer fees of any nature or kind that
may be payable in respect of the issue or delivery of such certificates, any such taxes or fees, if payable, to be paid by the
Company.


 




    	 	10	 



     


    

 


(4)       Reservation
of Common Stock. The Company shall take all action necessary to at all times have authorized, and reserved for the purpose
of issuance, three (3) times such number of shares of Common Stock as shall be necessary to effect the full conversion of the Debenture
in accordance with its terms (the “Share Reserve”).  If upon receipt of a conversion notice from the Holder,
the Share Reserve is insufficient to effect the full conversion of the Debenture then outstanding, the Company shall increase the
Share Reserve accordingly.  If the Company does not have sufficient authorized and unissued shares of Common Stock available
to increase the Share Reserve, the Company shall cause its authorized and unissued shares to be increased within forty-five (45)
days to an amount of shares equal to two (2) times the Conversion Shares. The Company’s management shall recommend to the
shareholders to vote in favor of increasing the number of shares of Common Stock authorized.


 


(5)       Make-Whole
Rights. Upon liquidation by the Holder of Conversion Shares issued pursuant to a Conversion Notice, provided that the Holder
realizes a net amount from such liquidation equal to less than the Conversion Amount specified in the relevant Conversion Notice
(such net realized amount, the “Realized Amount”), the Company shall issue to the Holder additional shares of
the Company’s Common Stock equal to: (i) the Conversion Amount specified in the relevant Conversion Notice; minus (ii)
the Realized Amount, as evidenced by a reconciliation statement from the Holder (a “Sale Reconciliation”) showing
the Realized Amount from the sale of the Conversion Shares; divided by (iii) the average volume weighted average price of
the Company’s Common Stock during the five (5) Business Days immediately prior to the date upon which the Holder delivers
notice (the “Make-Whole Notice”) to the Company that such additional shares are requested by the Holder (the
“Make-Whole Stock Price”) (such number of additional shares to be issued, the “Make-Whole Shares”).
Upon receiving the Make-Whole Notice and Sale Reconciliation evidencing the number of Make-Whole Shares requested, the Company
shall instruct its transfer agent to issue certificates representing the Make-Whole Shares, which Make-Whole Shares shall be issued
and delivered in the same manner and within the same time frames as set forth herein. The Make-Whole Shares, when issued, shall
be deemed to be validly issued, fully paid, and non-assessable shares of the Company’s Common Stock. Following the sale of
the Make-Whole Shares by the Holder: (i) in the event that the Holder receives net proceeds from such sale which, when added to
the Realized Amount from the prior relevant Conversion Notice, is less than the Conversion Amount specified in the relevant Conversion
Notice, the Holder shall deliver an additional Make-Whole Notice to the Company following the procedures provided previously in
this paragraph, and such procedures and the delivery of Make-Whole Notices and issuance of Make-Whole Shares shall continue until
the Conversion Amount has been fully satisfied; and (ii) in the event that the Holder received net proceeds from the sale of Make-Whole
Shares in excess of the Conversion Amount specified in the relevant Conversion Notice, such excess amount shall be applied to satisfy
any and all amounts owed hereunder in excess of the Conversion Amount specified in the relevant Conversion Notice.


 


(6)       Adjustments
to Conversion Price.


 




    	 	11	 



     


    

 


(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 shares of Common Stock on outstanding shares of Common Stock, (ii) subdivides
outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding
shares of Common Stock into a smaller number of shares, or (iv) issues, in the event of a reclassification of shares of Common
Stock, any shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock (excluding any treasury shares of the Company) outstanding immediately before
such event, and the denominator of which shall be the number of shares of Common Stock 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.


 


(b)       Fundamental
Transaction. If, at any time while this Debenture is outstanding: (i) the Company effects any merger or consolidation of the
Company with or into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one transaction
or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person) is completed
pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property,
or (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common
Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, 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, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence
of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one (1) share
of Common Stock (the “Alternate Consideration”). 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 Common Stock 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 Common Stock 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. To the extent necessary to effectuate the foregoing provisions,
any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new note consistent
with the foregoing provisions and evidencing the Holder’s right to convert such note into Alternate Consideration. The terms
of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving
entity to comply with the provisions of this Section and insuring that this Debenture (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.


 




    	 	12	 



     


    

 


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


 


(d)       Notice
to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C)
the Company shall authorize the granting to all holders of the Common Stock 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 Common Stock, any consolidation or merger to which the Company is a party, any sale
or transfer of all or substantially all of the assets of the Company, of any compulsory share exchange whereby the Common Stock
is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be 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 Company’s records, at least twenty (20) calendar days prior to the applicable record
or effective date hereinafter specified, a notice stating: (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of
the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined,
or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective
or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their
shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger,
sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders
of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver
such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to
be specified in such notice. The Holder is entitled to convert this Debenture during the 10-day period commencing on the date of
such notice through the effective date of the event triggering such notice.
