hereby promises to pay to the order of Jeffery Krueger, an individual investor, or registered assigns (the “Holder”)
the sum of Ten Thousand (10,000), a  six month note  to Jan 15, 2016 (the “Maturity Date”), and
to pay interest on the unpaid principal balance hereof at the rate of ten percent (10%) (The “Interest Rate”) per
annum from the date hereof (the “Issue Date”) until the same becomes due and payable, whether at maturity or upon
acceleration or by prepayment or otherwise, compounded on a monthly basis. This Note may not be prepaid in whole or in part except
as otherwise explicitly set forth in Section 1.9 hereof. Interest shall commence accruing on the Issue Date, shall be computed
on the basis of a 365-day year and the actual number of days elapsed. All payments d u e hereunder (to the extent not converted
into common stock, (the “Common Stock”) in accordance with the terms hereof) shall be made in lawful money of the
United States of America. All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written
notice made in accordance with the provisions of this Note. Whenever any amount expressed to be due by the terms of this Note
is due on any day which is not a business day, the same shall instead be due on the next succeeding day which is a business day
and, in the case of any interest payment date which is not the date on which this Note is paid in full, the extension of the due
date thereof shall not be taken into account for purposes of determining the amount of interest due on such date. As used in this
Note, the term “business day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks
in the city of New York, New York are authorized or required by law or executive order to remain closed. Each capitalized term
used herein, and not otherwise defined, shall have the meaning ascribed thereto in that certain Securities Exchange Agreement
dated the date hereof, pursuant to which this Note was originally issued (the “Exchange Agreement”). 


 


This
Note is free from all taxes, liens, claims and encumbrances w i t h respect to the issue thereof and shall not be subject to preemptive
rights or other similar rights of shareholders of the Borrower and will not impose personal liability upon the holder thereof.


 


The
following terms shall apply to this Note: 


 


ARTICLE
I. CONVERSION RIGHTS 


 


1.1
         Conversion Right. The Holder shall have the right from time to
time, and at any time during the period beginning 6 mo n t h s after the date of this Note and ending on the later of (i) the
Maturity Date and (ii) the date of payment of the Default Amount (as defined in Article III) pursuant to Section 1.6(a) or
Article III, each in respect of the remaining outstanding principal amount of this Note to convert all or any part of the
outstanding and unpaid principal amount of this Note into fully paid and non-assessable shares of Common Stock, as such
Common Stock exists on the Issue Date, or any shares of capital stock or other securities of the Borrower into which such
Common Stock shall hereafter be changed or reclassified at the conversion price (the “Conversion Price”)
determined as provided herein (a “Conversion”); provided, however, that in no event shall the
Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion of which the
sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares
of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes or the
unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise
analogous to the limitations contained herein). The number of shares of Common Stock to be issued upon each conversion of
this Note shall be determined by dividing the Conversion Amount (as defined below) by the applicable Conversion Price then in
effect on the date specified in the notice of conversion, in the form attached hereto as Exhibit A (the “Notice of
Conversion”), delivered to the Borrower by the Holder in accordance with Section 1.4 below; provided that the Notice of
Conversion is submitted by facsimile (or by other means resulting in, or reasonably expected to result in, notice) to the
Borrower before 6:00 p.m., New York, New York time on such conversion date (the “Conversion Date”). The term
“Conversion Amount” means, with respect to any conversion of this Note, the sum of (1) the principal amount of
this Note to be converted in such conversion plus (2) at the Borrower’s option, accrued and unpaid interest,
if any, on such principal amount at the interest rates provided in this Note to the Conversion Date, provided, however, that
the Company shall have the right to pay any or all interest in cash plus (3) at the Borrower’s option, Default
Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2) plus (4) at the
Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof.


 






    	1



    	 



    

  


1.2
           Conversion Price. The conversion price (the “Conversion Price”)
shall be at a fixed price. Conversion Price (as defined herein)(subject to equitable adjustments for stock splits, stock dividends
or rights offerings by the Borrower relating to the Borrower’s securities or the securities of any subsidiary of the Borrower,
combinations, recapitalization, reclassifications, extraordinary distributions and similar events). The “Fixed Conversion
Price” shall mean $0.05. If the Trading Price cannot be calculated for such security on such date in the manner
provided above, the Trading Price shall be the fair market value as mutually determined by the Borrower and the holders of a majority
in interest of the Notes being converted for which the calculation of the Trading Price is required in order to determine the
Conversion Price of such Notes. “Trading Day” shall mean any day on which the Common Stock is traded for any period
on the OTCQB, or on the principal securities exchange or other securities market on which the Common Stock is then being traded. 


 


1.3
           Method of Conversion. 


 


(a)
         Mechanics of Conversion. Subject to Section 1.1, this Note may be
converted by the Holder in whole or in part at any time from time to time after the Issue Date, by : (A) submitting to the Borrower
a Notice of Conversion (by facsimile, e-mail or other reasonable means of communication dispatched on the Conversion Date prior
to 6:00 p.m., New York, New York time) and (B) subject to Section 1.4(b), surrendering this Note at the principal office of the
Borrower. 


(b)
         Surrender of Note Upon Conversion. Notwithstanding anything to the
contrary set forth herein, upon conversion of this Note in accordance with the terms hereof, the Holder shall not be required
to physically surrender this Note to the Borrower unless the entire unpaid principal amount of this Note is so converted. The
Holder and the Borrower shall maintain records showing the principal amount so converted and the dates of such conversions or
shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require physical surrender of
this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower shall, prima
facie, be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion of
this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this
Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like
tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the
aggregate the remaining unpaid principal amount of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge
and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and
unconverted principal amount of this Note represented by this Note may be less than the amount stated on the face hereof. 


(c)
         Payment of Taxes. The Borrower shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock or other securities
or property on conversion of this Note in a name other than that of the Holder (or in street name), and the Borrower shall not
be required to issue or deliver any such shares or other securities or property unless and until the person or persons (other
than the Holder or the custodian in whose street name such shares are to be held for the Holder’s account) requesting the
issuance thereof shall have paid to the Borrower the amount of any such tax or shall have established to the satisfaction of the
Borrower that such tax has been paid.


(d)
         Delivery of Common Stock Upon Conversion. Upon receipt by the Borrower
from the Holder of a facsimile transmission or e-mail (or other reasonable means of communication) of a Notice of Conversion meeting
the requirements for conversion as provided in this Section 1.4, the Borrower shall issue and deliver or cause to be issued and
delivered to or upon the order of the Holder certificates for the Common Stock issuable upon such conversion within three (3)
business days after such receipt ( but in any event the fifth (5th) business day being hereinafter referred to as the “Deadline”)
(and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of the this Note) in accordance
with the terms hereof and the Exchange Agreement.


(e)
         Obligation of Borrower to Deliver Common Stock. Upon receipt by the
Borrower of a Notice of Conversion, the Holder shall be deemed to be the holder of record of the Common Stock issuable upon such
conversion, the outstanding principal amount and the amount of accrued and unpaid interest on this Note shall be reduced to reflect
such conversion, and, unless the Borrower defaults on its obligations under this Article I, all rights with respect to the portion
of this Note being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash
or other assets, as herein provided, on such conversion. If the Holder shall have given a Notice of Conversion as provided herein,
the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective
of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof, the
recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any
other obligation of the Borrower to the holder of record, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which
might otherwise limit such obligation of the Borrower to the Holder in connection with such conversion. The Conversion Date specified
in the Notice of Conversion shall be the Conversion Date so long as the Notice of Conversion is received by the Borrower before
6:00 p.m., New York, New York time, on such date.


 


 



    	2



    	 



    




 


(f)

         Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Common Stock
issuable upon conversion, provided the Borrower’s transfer agent is participating in the Depository Trust Company (“DTC”)
Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder and its compliance with the provisions
contained in Section 1.1 and in this Section 1.4, the Borrower shall use its best efforts to cause its transfer agent to electronically
transmit the Common Stock issuable upon conversion to the Holder by crediting the account of Holder’s Prime Broker with
DTC through its Deposit Withdrawal Agent Commission (“DWAC”) system.


(g)
         Failure to Deliver C o mmo n S t o c k Prior to Deadline. Without
in any way limiting the Holder’s right to pursue other remedies, including actual damages and/or equitable relief, the parties
agree that if delivery of the Common Stock issuable upon conversion of this Note is not delivered by the Deadline (other than
a failure due to the circumstances described in Section 1.3 above, which failure shall be governed by such Section) the Borrower
shall pay to the Holder $2,000 per day in cash, for each day beyond the Deadline that the Borrower fails to deliver such Common
Stock. Such cash amount shall be paid to Holder by the fifth day of the month following the month in which it has accrued or,
at the option of the Holder (by written notice to the Borrower by the first day of the month following the month in which it has
accrued), shall be added to the principal amount of this Note, in which event interest shall accrue thereon in accordance with
the terms of this Note and such additional principal amount shall be convertible into Common Stock in accordance with the terms
of this Note. The Borrower agrees that the right to convert is a valuable right to the Holder. The damages resulting from a failure,
attempt to frustrate, and interference with such conversion right are difficult if not impossible to qualify. Accordingly the
parties acknowledge that the liquidated damages provision contained in this Section 1.4(g) are justified. 


 


1.5
            Concerning the Shares. The shares of Common Stock
issuable upon conversion of this Note may not be sold or transferred unless (i) such shares are sold pursuant to an effective
registration statement under the Act or (ii) the Borrower or its transfer agent shall have been furnished with an opinion of counsel
(which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect
that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii)
such shares are sold or transferred pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv)
such shares are transferred to an “affiliate” (as defined in Rule 144) of the Borrower who agrees to sell or otherwise
transfer the shares only in accordance with this Section 1.5 and who is an Accredited Investor (as defined in the Exchange Agreement).
Except as otherwise provided in the Exchange Agreement (and subject to the removal provisions set forth below), until such time
as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act or otherwise may be sold
pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately
sold, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective
registration statement or that has not been sold pursuant to an effective registration statement or an exemption that permits
removal of the legend, shall bear a legend substantially in the following form, as appropriate: 


 


“NEITHER
THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT
BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE HOLDER), IN
A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE
144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT
OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.” 


 


The
legend set forth above shall be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer
legend if (i) the Borrower or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary
for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made
without registration under the Act, which opinion shall be accepted by the Company so that the sale or transfer is effected or
(ii) in the case of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Holder
under an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction
as to the number of securities as of a particular date that can then be immediately sold. In the event that the Company does not
accept the opinion of counsel provided by the Buyer with respect to the transfer of Securities pursuant to an exemption from registration,
such as Rule 144 or Regulations S, at the Deadline, it will be considered an Event of Default pursuant to Section 3.2 of the Note.

1.6             Effect
of Certain Events.


(a)
          Effect of Merger, Consolidation, Etc. At the option of the
Holder, the sale, conveyance or disposition of all or substantially all of the assets of the Borrower, the effectuation by the
Borrower of a transaction or series of related transactions in which more than 50% of the voting power of the Borrower is disposed
of, or the consolidation, merger or other business combination of the Borrower with or into any other Person (as defined below)
or Persons when the Borrower is not the survivor shall either: (i) be deemed to be an Event of Default (as defined in Article
III) pursuant to which the Borrower shall be required to pay to the Holder upon the consummation of and as a condition to such
transaction an amount equal to the Default Amount (as defined in Article III) or (ii) be treated pursuant to Section 1.6(b) hereof.
“Person” shall mean any individual, corporation, limited liability company, partnership, association, trust or other
entity or organization.


(b)          Adjustment
Due to Merger, Consolidation, Etc. If, at any time when this Note is issued and outstanding and prior to conversion of all
of the Notes, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar
event, as a result of which shares of Common Stock of the Borrower shall be changed into the same or a different number of shares
of another class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of
all or substantially all of the assets of the Borrower other than in connection with a plan of complete liquidation of the Borrower,
then the Holder of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon
the terms and conditions specified herein and in lieu of the shares of Common Stock immediately theretofore issuable upon conversion,
such stock, securities or assets which the Holder would have been entitled to receive in such transaction had this Note been converted
in full immediately prior to such transaction (without regard to any limitations on conversion set forth herein), and in any such
case appropriate provisions shall be made with respect to the rights and interests of the Holder of this Note to the end that
the provisions hereof (including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares
issuable upon conversion of the Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities
or assets thereafter deliverable upon the conversion hereof. The Borrower shall not affect any transaction described in this Section
1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days prior written notice (but in any event at least
fifteen (15) days prior written notice) of the record date of the special meeting of shareholders to approve, or if there is no
such record date, the consummation of, such merger, consolidation, exchange of shares, recapitalization, reorganization or other
similar event or sale of assets (during which time the Holder shall be entitled to convert this Note) and (b) the resulting successor
or acquiring entity (if not the Borrower) assumes by written instrument the obligations of this Section 1.6(b). The above provisions
shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges.


(c)          Adjustment
Due to Distribution. If the Borrower shall declare or make any distribution of its assets (or rights to acquire its assets)
to holders of Common Stock as a dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or
distribution to the Borrower’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary
(i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this
Note after the date of record for determining shareholders entitled to such Distribution, to receive the amount of such assets
which would have been payable to the Holder with respect to the shares of Common Stock issuable upon such conversion had such
Holder been the holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such
Distribution, but only if such Distribution occurs within 365 days of the date of this Note.


(d)
          Purchase Rights. If, at any time when any Notes are issued
and outstanding, the Borrower issues any convertible securities or rights to purchase stock, warrants, securities or other property
(the “Purchase Rights”) pro rata to the record holders of any class of Common Stock, then the Holder of this Note
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder
could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note
(without regard to any limitations on conversion contained herein) 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
Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.


(e)
          Notice of Adjustments. Upon the occurrence of each adjustment
or readjustment of the Conversion Price as a result of the events described in this Section 1.6, the Borrower, at its expense,
shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder of a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Borrower shall,
upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment
or readjustment, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount,
if any, of other securities or property which at the time would be received upon conversion of the Note. 


 


1.7
             Trading Market Limitations. Unless permitted by the applicable rules and regulations of the principal securities market
on which the Common Stock is then listed or traded, in no event shall the Borrower issue upon conversion of or otherwise pursuant
to this Note and the other Notes issued pursuant to the Exchange Agreement more than the maximum number of shares of Common Stock
that the Borrower can issue pursuant to any rule of the principal United States securities market on which the Common Stock is
then traded (the “Maximum Share Amount”), which shall be 9.99% of the total shares outstanding on the Closing Date
(as defined in the Exchange Agreement), subject to equitable adjustment from time to time for stock splits, stock dividends, combinations,
capital reorganizations and similar events relating to the Common Stock occurring after the date hereof. Once the Maximum Share
Amount has been issued, if the Borrower fails to eliminate any prohibitions under applicable law or the rules or regulations of
any stock exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over the Borrower or
any of its securities on the Borrower’s ability to issue shares of Common Stock in excess of the Maximum Share Amount, in
lieu of any further right to convert this Note, this will be considered an Event of Default under Section 3.3 of the Note.


 




    	4



    	 



    

 


1.8
          Status as Shareholder. Upon submission of a Notice of Conversion
by a Holder, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would
exceed such Holder’s allocated portion of the Reserved Amount or Maximum Share Amount) shall be deemed converted into shares
of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of this Note shall cease and terminate,
excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise
available at law or in equity to such Holder because of a failure by the Borrower to comply with the terms of this Note. Notwithstanding
the foregoing, if a Holder has not received certificates for all shares of Common Stock prior to the tenth (10th) business day
after the expiration of the Deadline with respect to a conversion of any portion of this Note for any reason, then (unless the
Holder otherwise elects to retain its status as a holder of Common Stock by so notifying the Borrower) the Holder shall regain
the rights of a Holder of this Note with respect to such unconverted portions of this Note and the Borrower shall, as soon as
practicable, return such unconverted Note to the Holder or, if the Note has not been surrendered, adjust its records to reflect
that such portion of this Note has not been converted. In all cases, the Holder shall retain all of its rights and remedies (including,
without limitation, (i) the right to receive Conversion Default Payments pursuant to Section 1.3 to the extent required thereby
for such Conversion Default and any subsequent Conversion Default and (ii) the right to have the Conversion Price with respect
to subsequent conversions determined in accordance with Section 1.3) for the Borrower’s failure to convert this Note. 


 


1.9
          Prepayment Option-Notwithstanding anything to the contrary
contained in this Note, so long as the Borrower has not received a Notice of Conversion from the Holder, the Borrower shall have
the right, exercisable in ten (10) Business Days post written notice to the Holder of the Note to prepay the outstanding Note
with principal and accrued interest. Any notice of prepayment herein (Optional Prepayment Notice) hereunder shall be delivered
to the Holder of the Note at its registered address and shall state: (1) that the Borrower is exercising its right to prepay the
Note, and (2) the date of prepayment which shall be not more than Five (5) Business Days from the date of the Optional Prepayment
Notice (the Optional Prepayment Date) (3) the calculated interest and principle due on the Date of the Optional Prepayment Notice,
(4) the title and address of payment per section 8(f) of this Agreement. If the Borrower exercises its right to prepay the Note,
the Borrower shall make payment to the Holder of an amount (the “Optional Prepayment Amount”) equal to 135% ,multiplied
by the sum of: (A) the then outstanding principal amount of this Note plus (B) accrued and unpaid interest on the unpaid
principal amount of this Note to the Optional Prepayment Notice. If the Company delivers the Optional Prepayment Notice and fails
to pay the Optional Prepayment due to the Buyer of the Note within two (2) business days following the Optional Prepayment Date,
the Company shall forfeit its right to prepay the Note.

Upon
the occurrence and during the continuation of any Event of Default specified in Section 3.1 (solely with respect to failure to
pay the principal hereof or interest thereon when due at the Maturity Date), the Note shall become immediately due and payable
and the Borrower shall pay to the Holder, in full satisfaction of its obligations hereunder, an amount equal to the Default Sum
(as defined herein). UPON THE OCCURRENCE AND DURING THE CONTINUATION OF ANY EVENT OF DEFAULT SPECIFIED IN SECTION 3.2, THE NOTE
SHALL BECOME IMMEDIATELY DUE AND PAYABLE AND THE BORROWER SHALL PAY TO THE HOLDER, IN FULL SATISFACTION OF ITS OBLIGTAIONS HEREUNDER,
AN AMOUNT EQUAL TO: (Y) THE DEFAULT SUM (AS DEFINED HEREIN); MULTIPLIED BY (Z) TWO (2). Upon the occurrence and during the continuation
of any Event of Default specified in Sections 3.1 (solely with respect to failure to pay the principal hereof or interest thereon
when due on this Note upon a Trading Market Prepayment Event pursuant to Section 1.7 or upon acceleration), 3.3, 3.4, 3.6, 3.8,
3.9, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, and/or 3.20 exercisable through the delivery of written notice to the
Borrower by such Holders (the “Default Notice”), and upon the occurrence of an Event of Default specified in the remaining
sections of Articles III (other than failure to pay the principal hereof or interest thereon at the Maturity Date specified in
Section 3.1 hereof), Borrower must remedy or cure the Default described within the Default Notice within ten (10) business days
or the Note shall become immediately due and payable and the Borrower shall pay to the Holder, in full satisfaction of its obligations
hereunder, an amount equal to the greater of (i) 150% times the sum of (w) the then outstanding principal amount
of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note to the date of payment (the
“Mandatory Prepayment Date”) plus (y) Default Interest, if any, on the amounts referred to in clauses (w) and/or
(x) plus (z) any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof (the then outstanding principal
amount of this Note to the date of payment plus the amounts referred to in clauses (x), (y) and (z) shall collectively
be known as the “Default Sum”) or (ii) the “parity value” of the Default Sum to be prepaid, where parity
value means (a) the highest number of shares of Common Stock issuable upon conversion of or otherwise pursuant to such Default
Sum in accordance with Article I, treating the Trading Day immediately preceding the Mandatory Prepayment Date as the “Conversion
Date” for purposes of determining the lowest applicable Conversion Price, unless the Default Event arises as a result of
such breach in respect of a specific Conversion Date in which case such Conversion Date shall be the Conversion Date, multiplied
by (b) the highest Closing Price for the Common Stock during the period beginning on the date of first occurrence of the Event
of Default and ending one day prior to the Mandatory Prepayment Date (the “Default Amount”) and all other amounts
payable hereunder shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are
expressly waived, together with all costs, including, without limitation, legal fees and expenses, of collection, and the Holder
shall be entitled to exercise all other rights and remedies available at low or in equity.


  


If
the Borrower fails to pay the Default Amount within ten (10) business days of written notice that such amount is due and payable,
then the Holder shall have the right at any time, so long as the Borrower remains in default (and so long and to the extent that
there are sufficient authorized shares), to require the Borrower, upon written notice, to immediately issue, in lieu of the Default
Amount, the number of shares of Common Stock of the Borrower equal to the Default Amount divided by the Conversion Price then
in effect.

IV. MISCELLANEOUS


 


4.1
          Failure or Indulgence Not Waiver. No failure or delay on the

4.3
          Amendments. This Note and any provision hereof may only be
amended by an instrument in writing signed by the Borrower and the Holder. The term “Note” and all reference thereto,
as used throughout this instrument, shall mean this instrument (and the other Notes issued pursuant to the Exchange Agreement)
as originally executed, or if later amended or supplemented, then as so amended or supplemented. 


 


4.4
          Assignability. This Note shall be binding upon the Borrower
and its successors and assigns, and shall inure to be the benefit of the Holder and its successors and assigns. Each transferee
of this Note must be an “accredited investor” (as defined in Rule 501(a) of the 1933 Act). Notwithstanding anything
in this Note to the contrary, this Note may be pledged as collateral in connection with a bona fide margin account
or other lending arrangement. 


 


4.5          Cost
of Collection. If default is made in the payment of this Note, the Borrower shall pay the Holder hereof costs of collection,
including reasonable attorneys’ fees. 


 


4.6
          Governing Law. This Note shall be governed by and
construed in accordance with the laws of the State of Nevada without regard to principles of conflicts of laws. Any action
brought by either party against the other concerning the transactions contemplated by this Note shall be brought only in the
state courts of Nevada or in the federal courts located in the state and county of Nevada. The parties to this Note hereby
irrevocably waive any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense
based on lack of jurisdiction or venue or based upon forum non conveniens. The Borrower and Holder waive trial by
jury. The prevailing party shall be entitled to recover from the other party its reasonable attorney’s fees and costs. In the
event that any provision of this Note or any other agreement delivered in connection herewith is invalid or unenforceable
under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform to such statute or rule of law. Any such provision which may prove
invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of any
agreement. Each party hereby irrevocably waives personal service of process and consents to process being served in any suit,
action or proceeding in connection with this Agreement or any other Transaction Document 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 Agreement 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 law.

4.7
          Certain Amounts. Whenever pursuant to this Note the Borrower
is required to pay an amount in excess of the outstanding principal amount (or the portion thereof required to be paid at that
time) plus accrued and unpaid interest plus Default Interest on such interest, the Borrower and the Holder agree that the actual
damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid
by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder in part for loss of the
opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this
Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower and the Holder hereby agree that
such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash
payment without the opportunity to convert this Note into shares of Common Stock. 


 


4.8
          Exchange Agreement. By its acceptance of this Note, each party
agrees to be bound by the applicable terms of the Exchange Agreement. 


 


4.9
          Notice of Corporate Events. Except as otherwise provided below,
the Holder of this Note shall have no rights as a Holder of Common Stock unless and only to the extent that it converts this Note
into Common Stock. The Borrower shall provide the Holder with prior notification of any meeting of the Borrower’s shareholders
(and copies of proxy materials and other information sent to shareholders). In the event of any taking by the Borrower of a record
of its shareholders for the purpose of determining shareholders who are entitled to receive payment of any dividend or other distribution,
any right to subscribe for, purchase or otherwise acquire (including by way of merger, consolidation, reclassification or recapitalization)
any share of any class or any other securities or property, or to receive any other right, or for the purpose of determining shareholders
who are entitled to vote in connection with any proposed sale, lease or conveyance of all or substantially all of the assets of
the Borrower or any proposed liquidation, dissolution or winding up of the Borrower, the Borrower shall mail a notice to the Holder,
at least twenty (20) days prior to the record date specified therein (or thirty (30) days prior to the consummation of the transaction
or event, whichever is earlier), of the date on which any such record is to be taken for the purpose of such dividend, distribution,
right or other event, and a brief statement regarding the amount and character of such dividend, distribution, right or other
event to the extent known at such time. The Borrower shall make a public announcement of any event requiring notification to the
Holder hereunder substantially simultaneously with the notification to the Holder in accordance with the terms of this Section
4.9. 


 


4.10
          Remedies. The Borrower acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to the Holder, by vitiating the intent and purpose of the transaction contemplated
hereby. Accordingly, the Borrower acknowledges that the remedy at law for a breach of its obligations under this Note will be
inadequate and agrees, in the event of a breach or threatened breach by the Borrower of the provisions of this Note, that the
Holder shall be entitled, in addition to all other available remedies at law or in equity, and in addition to the penalties assessable
herein, to an injunction or injunctions restraining, preventing or curing any breach of this Note and to enforce specifically
the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security being
required. Both the Borrower and the Holder may seek specific performance of the terms and provisions herein. 


 


4.11
          Severability. If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note 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 shall violate
applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum
permitted rate of interest. The Borrower 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 Borrower from paying all or any portion of the principal of or interest on this Note as
contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance
of this indenture, and the Borrower (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of
any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein
granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.
