equal to twelve percent (12%) and shall be computed on the basis of a 365-day year.


 


2.2
Consideration. In consideration for the Debenture, Holder shall pay to Borrower a purchase price equal to Thirty Eight
Thousand Dollars ($38,000) payable by wire transfer or other immediately available funds. Thus, as of the Issuance Date, there
shall exist a Seven Thousand Dollar ($7,000) Original Issue Discount (the “OID”) from the Principal Amount.
Interest shall accrue and be payable on the full Principal Amount of the Debenture, inclusive of the OID, and payment of the full
Principal Amount shall be required regardless of time and manner of payment or prepayment by Borrower. Upon conversion, Holder
shall receive credit for the full Principal Amount converted.

Date.


 



    	 	3	 



    	 		 



    

 


2.4
Prepayment Option. Subject to the approval of Holder for prepayments after one hundred eighty (180) days, Borrower may
prepay in cash all or any portion of the Principal Amount of this Debenture and accrued interest thereon, with a premium, as set

Shares will be returned in the event that this Debenture is prepaid. Failure to issue and deliver the Commitment Fee Shares to
Holder within fifteen (15) Business Days shall constitute an Event of Default under this Debenture.


 


ARTICLE

CONVERSION REPAYMENT


 


3.1.
Optional Conversion. Subject to the terms of this Article III, Holder shall have the right, but not the obligation, at
any time after the Issuance Date and until the Maturity Date, or thereafter during an Event of Default, to convert all or any
portion of the outstanding Principal Amount, accrued interest and fees due and payable thereon into fully paid and non-assessable
shares of Common Stock of Borrower at the Conversion Price, as defined below (the “Conversion Shares”).


 


3.2.
Calculation of Conversion Price. Subject to Section 3.2.1 and 4.6 hereof, the conversion price (the “Conversion
Price”) shall mean the lesser of (a) sixty percent (60%) multiplied by the Lowest Closing Price as of the date

Conversion Price Adjustments. Conversion Price shall be subject to the following adjustments:


 


	 	i.	If
    the market capitalization of the Borrower is less than Two Million Dollars ($2,000,000) on the day immediately prior to the
    date of the Notice of Conversion, then the Conversion Price shall be twenty-five percent (25%) multiplied by the Lowest Closing
    Price as of the date a Notice of Conversion is given (which represents a discount rate of seventy-five percent (75%)); and
	 	 	 
	 	ii.	If
    the closing price of the Borrower’s Common Stock on the day immediately prior to the date of the Notice of Conversion
    is less than two-tenths of a penny ($0.002) then the Conversion Price shall be twenty-five percent (25%) multiplied by the
    Lowest Closing Price as of the date a Notice of Conversion is given (which represents a discount rate of seventy-five percent
    (75%)).


 



    	 	4	 



    	 		 



    

 


3.3.
Conversion Limitation. Notwithstanding anything contained herein to the contrary, the number of Conversion Shares that
may be acquired by Holder upon conversion of this Debenture (or otherwise in respect hereof) shall be limited to the extent necessary
to ensure that, following such conversion (or other issuance), the total number of shares of Common Stock then beneficially owned
by Holder and its affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with that of
Holder for purposes of Section 13(d) of the Exchange Act does not exceed 4.99% of the total number of issued and outstanding shares
of Common Stock, including, for such purpose, the shares of Common Stock issuable upon such conversion, but excluding the number
of shares of Common Stock issuable upon (a) conversion of the remaining, unconverted Principal Amount of this Debenture beneficially
owned by Holder or any of its affiliates and (b) exercise or conversion of the unexercised or unconverted portion of any other
securities of Borrower subject to a limitation on conversion or exercise analogous to the limitation contained herein (including,
without limitation, any other debenture or warrant) beneficially owned by Holder or any of its affiliates. For such purposes,
beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.


 


3.4.
Mechanics of Holder’s Conversion. Subject to Section 3.3 hereof, this Debenture may be converted by Holder, in whole
or in part from time to time after the Issuance Date, by submitting to Borrower and/or the transfer agent of record a notice of
conversion (“Notice of Conversion”), the form of which is attached hereto as Exhibit A. Such Notice
of Conversion shall specify the Principal Amount of the Debenture to be converted and the date on which such conversion shall
be effected (the “Conversion Date”). Pursuant to the terms of the Notice of Conversion, Borrower shall issue
instructions to the transfer agent within two (2) Trading Days from the receipt of the Notice of Conversion and shall cause the
transfer agent to transmit the certificates representing the Conversion Shares to Holder by physical delivery or crediting the
account of Holder’s designated broker with the Depository Trust Corporation (“DTC”) through its Deposit
Withdrawal Agent Commission (“DWAC”) system within two (2) Trading Days after receipt by Borrower of the Notice
of Conversion (the “Delivery Date”). In the case of the exercise of the conversion rights set forth herein,
the conversion privilege shall be deemed to have been exercised, and the Conversion Shares issuable upon such conversion shall
be deemed to have been issued, upon the Delivery Date and Holder shall be treated for all purposes as the record holder of such
Common Stock, unless Holder provides Borrower with written instructions to the contrary. Conversions hereunder shall have the
effect of lowering the outstanding Principal Amount of this Debenture in an amount equal to the applicable conversion. Holder
and Borrower shall maintain records showing the Principal Amount(s) converted and the Conversion Date(s). In the event of any
dispute or discrepancy, the records of Holder shall be controlling and determinative in the absence of manifest error.


 


3.5.
Conversion Mechanics. The number of shares of Common Stock to be issued upon each conversion of this Debenture shall be
determined by dividing that portion of the Principal Amount and interest and fees to be converted, if any, by the then applicable
Conversion Price.


 


3.6
Fractional Shares. No fractional shares shall be issued upon the conversion of this Debenture. As to any fraction of a
share which Holder would otherwise be entitled to upon such conversion, Borrower shall round up to the next whole share.


 


3.7
Late Delivery of Conversion Shares. Borrower understands that a delay in the delivery of Conversion Shares in the form
required pursuant to this Article III beyond the Delivery Date could result in economic loss to Holder. As compensation to Holder
for such loss, Borrower agrees to pay late fees to Holder for late issuance of such shares in the form required pursuant to this
Article III upon conversion of the Debenture, in the amount equal to one thousand dollars ($1,000) per Business Day after the
Delivery Date. Borrower shall pay any fees incurred under this Section in immediately available funds upon demand and such fees
shall also be eligible to be converted into Common Stock pursuant to this Article III.


 



    	 	5	 



    	 		 



    

 


3.8
Authorized and Reserved Shares. Borrower represents and warrants and covenants and agrees that upon issuance, the Conversion
Shares will be duly and validly issued, fully issued and non-assessable. Borrower agrees that its issuance of this Debenture shall
constitute full authority to its officers and agents who are charged with the duty of executing stock certificates to execute
and issue the necessary certificates for Conversion Shares in accordance with the terms and conditions of this Debenture. At all
times during which this Debenture is outstanding, Borrower shall reserve and keep available from its authorized and unissued shares
of Common Stock (the “Share Reserve”) for the sole 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 or contingent
purchase rights of Persons other than Holder, not less than five times the aggregate number of shares of the Common Stock that
shall be issuable (taking account the adjustments of Article IV) upon the conversion of the outstanding Principal Amount of this
Debenture and payment of interest hereunder. Initially, the Share Reserve shall be equal to one hundred fifty million (150,000,000)
shares. The Holder may request bi-monthly increases to reserve such amounts based on a conversion price equal to the Lowest Closing
Price, as defined in the Debenture, as of such date, by written instructions from the Holder to the Transfer Agent to comply with
the required reserve. Borrower agrees that it will take all such reasonable actions as may be necessary to assure that the Conversion
Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the applicable
Trading Market upon which the Common Stock may be listed. Borrower agrees to provide Holder with confirmation evidencing the execution
of such share reservation within fifteen (15) Business Days from the Issuance Date.


 


3.9
Issuance of New Debenture. Upon any partial conversion of this Debenture, a new Debenture containing the same date and
provisions of this Debenture shall, at the request of Holder, be issued by Borrower to Holder for the principal balance of this
Debenture and accrued interest which shall not have been converted or paid. Subject to the provisions of Article VI, Borrower
will pay no costs, fees or any other consideration to Holder for the production and issuance of a new Debenture.


 


3.10
Par Value; Further Assurances.


 


(a)
Borrower covenants that during the period that the Principal Amount of this Debenture and any accrued interest and fees thereon
remain outstanding, it will ensure that the par value of any Conversion Shares shall not exceed the amount payable therefor upon
such exercise immediately prior to such exercise. Borrower further covenants that it shall take all appropriate actions, including,
without limitation, amending its articles or certificate of incorporation and any other voluntary action, such as calling a meeting
of stockholders to approve any such amendment, to ensure that the amount payable for any Conversion Shares shall at all times
exceed the par value thereof by at least four hundred percent (400%).


 


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


 



    	 	6	 



    	 		 



    

 


3.11
Transfer Taxes. The issuance of certificates for Conversion Shares shall be made without charge to Holder for any documentary
stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided that Borrower 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
certificate upon conversion in a name other than that of Holder and Borrower shall not be required to issue or deliver such certificates
unless or until the Person or Persons requesting the issuance thereof shall have paid to Borrower the amount of such tax or shall
have established to the satisfaction of Borrower that such tax has been paid.


 


3.12
Rule 144 Issuer’s Representation Letter. In the event that Holder’s brokers dealer requires a Rule 144 Issuer’s
Representation Letter (the “144 Letter”), Holder will submit to Borrower the 144 Letter along with a corresponding
Notice of Conversion upon which Borrower will have forty-eight (48) hours to execute and return the 144 Letter.


 


ARTICLE
IV

CERTAIN ADJUSTMENTS


 


4.1
Stock Dividends and Stock Splits. If Borrower, at any time while this Debenture is outstanding: (a) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by Borrower upon conversion of,
or payment of interest on, this Debenture); (b) subdivides outstanding shares of Common Stock into a larger number of shares;
or (c) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of Borrower, then
the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding
any treasury shares of Borrower) outstanding immediately before such event and of which the denominator 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.


 


4.2
Subsequent Rights Offerings. If Borrower, at any time within six (6) months of the Issuance Date, shall issue rights, options
or warrants to all holders of Common Stock (and not to Holder) entitling them to subscribe for or purchase shares of Common Stock
at a price per share that is lower than the Lowest Closing Price on the record date referenced below, then the Conversion Price
shall be multiplied by a fraction of which the denominator shall be the number of shares of the Common Stock outstanding on the
date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase,
and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights
or warrants plus the number of shares which the aggregate offering price of the total number of shares issued (assuming delivery
to Borrower in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such Lowest
Closing Price. Such adjustment shall be made whenever such rights or warrants are issued, other than to officers and directors
under equity incentive plans approved by the board of directors, and shall become effective immediately after the record date
for the determination of stockholders entitled to receive such rights, options or warrants.


 



    	 	7	 



    	 		 



    

 


4.3
Pro Rata Distributions. If Borrower, at any time while this Debenture is outstanding, distributes to all holders of Common
Stock (and not to Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to
subscribe for or purchase any security (other than the Common Stock, which shall be subject to Section 4.1), then in each such
case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be
the Lowest Closing Price determined as of the record date mentioned above, and of which the numerator shall be such Lowest Closing
Price on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness
so distributed applicable to one (1) outstanding share of the Common Stock as determined by the board of directors of Borrower
in good faith. In either case the adjustments shall be described in a statement delivered to Holder describing the portion of
assets or evidences of indebtedness so distributed or such subscription rights applicable to one (1) share of Common Stock. Such
adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned
above.


 


4.4
Fundamental Transaction. If, at any time while this Debenture is outstanding, (a) Borrower effects any merger or consolidation
of Borrower with or into another Person, (b) Borrower effects any sale of all or substantially all of its assets in one transaction
or a series of related transactions, (c) any tender offer or exchange offer (whether by Borrower 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 (d) Borrower 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, 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, 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 Borrower 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 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 Borrower or surviving entity in such Fundamental Transaction shall issue to Holder a new Debenture consistent with the foregoing
provisions and evidencing Holder’s right to convert such Debenture 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 4.4 and insuring that this Debenture (or any such replacement security) will be similarly
adjusted upon any subsequent transaction analogous to a Fundamental Transaction.


 


4.5
Calculations. All calculations under this Article III shall be made to four decimal places or the nearest 1/100th of a
share, as the case may be. For purposes of this Article III, the number of shares of Common Stock deemed to be issued and outstanding
as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of Borrower) issued
and outstanding.


 



    	 	8	 



    	 		 



    

 


4.6
Notice to Holder.


 


a)
Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Article IV,
Borrower 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.


 


b)
Notice to Allow Conversion by Holder. If (i) Borrower shall declare a dividend (or any other distribution in whatever form)
on the Common Stock, (ii) Borrower shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock,
(iii) Borrower 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, (iv) the approval of any stockholders of Borrower shall be required
in connection with any reclassification of the Common Stock, any consolidation or merger to which Borrower is a party, any sale
or transfer of all or substantially all of the assets of Borrower, of any compulsory share exchange whereby the Common Stock is
converted into other securities, cash or property or (v) Borrower shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of Borrower, then, in each case, Borrower 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 Holder at its last address as it shall appear
upon Borrower’s books and records, at least 20 calendar days prior to the applicable record or effective date hereinafter
specified, a notice stating (A) 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 (B) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it
is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities,
cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided
that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the
corporate action required to be specified in such notice. Holder is entitled to convert this Debenture during the 20-day period
commencing on the date of such notice through the effective date of the event triggering such notice.


 


4.7
Most Favored Nations Status. So long as this Debenture is outstanding, upon any issuance by Borrower or any of its subsidiaries
of any security (in an amount under one million dollars ($1,000,000)) with any term more favorable to the holder of such security
or with a term in favor of the holder of such security that was not similarly provided to Holder in this Debenture, then Borrower
shall notify Holder of such additional or more favorable term and such term, at Holder’s option, shall become a part of
the transaction documents with Holder. Such more favorable terms include, but are not limited to, terms addressing conversion
discounts, conversion look-back periods, interest rates, original issue discounts, stock sale price, private placement price per
share and warrant coverage.


 


4.8
Holder’s Adjustments. Upon the occurrence of either of the following events, Holder may provide the transfer agent
with written instructions to increase the Share Reserve in accordance therewith: (a) closing price of Borrower’s Common

DEFAULT
RELATED PROVISIONS AND OTHER PRIVILEGES


 


7.1
Default Interest Rate. If any Event of Default occurs, the outstanding Principal Amount of this Debenture, plus accrued
but unpaid interest, liquidated damages and other amounts owing in respect thereof through the date of acceleration, shall become,
at Holder’s election, immediately due and payable in cash in the sum of (a) one hundred eighteen percent (118%) of the outstanding
Principal Amount of this Debenture plus one hundred percent (100%) of accrued and unpaid interest thereon and (b) all other amounts,
costs, expenses and liquidated damages due in respect of this Debenture (“Mandatory Default Amount”). After
the occurrence of any Event of Default, the interest rate on this Debenture shall accrue at an interest rate equal to the lesser
of eighteen percent (18%) per annum or the maximum rate permitted under applicable law, effective as of the Issuance Date of this
Debenture. Upon the payment in full of the Mandatory Default Amount, Holder shall promptly surrender this Debenture to or as directed
by Borrower. In connection with such acceleration described herein, Holder need not provide, and Borrower hereby waives, any presentment,
demand, protest or other notice of any kind, and 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 Holder shall have all rights as a holder of his
Debenture until such time, if any, as Holder receives full payment pursuant to this Section 7.1. No such rescission or annulment
shall affect any subsequent Event of Default or impair any right consequent thereon.

date of the Event of Default. Borrower shall pay any fees incurred under this Section in immediately available funds upon demand
and such fees shall also be eligible to be converted into Conversion Shares as set forth in Article III. Such conversion privileges
shall remain in full force and effect immediately from the date hereof and until this Debenture is paid in full.

MISCELLANEOUS


 


8.1
Piggyback Registration Rights. Borrower shall include on the next registration statement Borrower files with the SEC (or
on the subsequent registration statement if such registration statement is withdrawn) all shares issuable upon conversion of this
Debenture. Failure to do so will result in liquidated damages of twenty-five percent (25%) of the outstanding Principal Amount
of this Debenture, but not less than twenty-five thousand dollars ($25,000), being immediately due and payable to Holder at its
election in the form of cash payment or addition to the balance of this Debenture. Notwithstanding the foregoing, in the event
a registration statement is filed with respect to an underwritten offering or a selling stockholder registration statement relating
solely to holders of Borrower’s Common Stock who paid cash for such Common Stock in a sale placed by an independent placement
agent, the number of shares of Common Stock owned by Holder to be included in any such registration statement may be limited if
in the opinion of the underwriter or placement agent, the sale of such shares by Holder would adversely impact the sale of shares
by the underwriter or selling stockholders included therein.


 


8.2
Failure or Indulgence Not Waiver. No failure or delay on the part of Holder hereof in the exercise of any power, right
or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other right, power or privilege. All rights and remedies existing
hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available.


 


8.3
Notices. All notices, demands, requests, consents, approvals, and other communications required or permitted hereunder

charges prepaid, (iv) transmitted by hand delivery, telegram, e-mail or facsimile, addressed as set forth below or (v) sent via
Email whereby a return Email confirming receipt has been delivered. Any notice or other communication required or permitted to
be given hereunder shall be deemed effective (y) upon hand delivery or delivery by facsimile, with accurate confirmation generated
by the transmitting facsimile machine, at the address or number designated below (if delivered on a Business Day during normal
business hours where such notice is to be received), or the first Business Day following such delivery (if delivered other than

the date of mailing by express courier service, fully prepaid, addressed to such address, or upon actual receipt of such mailing,
whichever shall first occur. The addresses for such communications shall be:

8.7
Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Debenture shall be governed by, and construed in accordance

ANY RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS DEBENTURE OR ANY TRANSACTION CONTEMPLATED

competent jurisdiction for preliminary or interim equitable relief, or to compel arbitration in accordance with this paragraph.
The expenses of the arbitration, including the arbitrator’s fees and expert witness fees, incurred by the parties to the
arbitration, may be awarded to the prevailing party, in the discretion of the arbitrator, or may be apportioned between the parties
in any manner deemed appropriate by the arbitrator. Unless and until the arbitrator decides that one party is to pay for all (or
a share) of such expenses, both parties shall share equally in the payment of the arbitrator’s fees as and when billed by
the arbitrator.


 


8.8
