CONVERTIBLE
PROMISSORY NOTE


 


FOR
VALUE RECEIVED, COATES INTERNATIONAL, LTD., a Delaware corporation (hereinafter called the “Borrower”),
hereby promises to pay to the order of AUCTUS PRIVATE EQUITY FUND, LLC, a Massachusetts limited liability company, or registered
assigns (the “Holder”) the sum of US$40,000 together with any interest as set forth herein, on January 14, 2015 (the
“Maturity Date”), and to pay interest on the unpaid principal balance hereof at the rate of eight percent (8%) (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. This Note may not be prepaid in whole or in part except
as otherwise explicitly set forth herein with the written consent of the Holder which may be withheld for any reason or for no
reason. Any amount of principal or interest on this Note which is not paid when due shall bear interest at the rate of twenty
two percent (22%) per annum from the due date thereof until the same is paid (“Default Interest”). Interest shall
commence accruing on the date that the Note is fully paid and shall be computed on the basis of a 365-day year and the actual
number of days elapsed. All payments due hereunder (to the extent not converted into common stock, $0.0001 par value per share
(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 Purchase Agreement dated the date hereof, pursuant to which
this Note was originally issued (the “Purchase Agreement”).

This
Note is free from all taxes, liens, claims and encumbrances with 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


 


1.1Conversion
Right. The Holder shall have the right from time to time, and at any time during the period beginning on the date which is
one hundred eighty (180) days following 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 (as defined below) 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) and (2) the number of shares of Common Stock issuable upon the conversion of the
portion of this Note with respect to which the determination of this proviso is being made, would result in beneficial ownership
by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock. For purposes of the proviso to
the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), and Regulations 13D-G thereunder, except as otherwise provided
in clause (1) of such proviso, provided, further, however, that the limitations on conversion may be waived
by the Holder upon, at the election of the Holder, not less than 61 days’ prior notice to the Borrower, and the provisions
of the conversion limitation shall continue to apply until such 61st day (or such later date, as determined by the Holder, as
may be specified in such notice of waiver). 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 e-mail (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 Holder’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 Borrower shall have the right to pay any or all interest
in cash plus (3) at the Holder’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.

1.2Conversion
Price.


 


(a)      Calculation
of Conversion Price. The conversion price (the “Conversion Price”) shall equal the Base 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 "Base Conversion Price" shall mean 67.5% multiplied by the Market
Price (as defined herein) (representing a discount rate of 32.5%). “Market Price” means the average of the lowest
two (2) Trading Prices (as defined below) for the Common Stock during the twenty-five (25) Trading Day period ending on the latest
complete Trading Day prior to the Conversion Date. “Trading Price” means, for any security as of any date, the closing
price on the Over-the-Counter Bulletin Board (the “OTCBB”), OTCQB or applicable trading market as reported by a reliable
reporting service (“Reporting Service”) designated by the Holder or, if the OTCQB is not the principal trading market
for such security, the closing price of such security on the principal securities exchange or trading market where such security
is listed or traded or, if no closing price of such security is available in any of the foregoing manners, the average of the
closing prices of any market makers for such security that are listed in the “pink sheets” by the National Quotation
Bureau, Inc. The Conversion Price may be adjusted downward if, within three (3) business days of the transmittal of the Notice
of Conversion to the Borrower, the Common Stock has a closing price which is 5% or lower than that set forth in the Notice of
Conversion. If the shares have not been delivered within three (3) business days to the Company, the Notice of Conversion may
be rescinded. In the case that the Borrower’s Common Stock is not deliverable by DWAC, an additional 5% discount will apply.
In the case that the Borrower’s Common Stock is “chilled” for deposit into the DTC system and only eligible
for clearing deposit, an additional 10% discount shall apply while the "chill" is in effect. 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 tradable for any period on the OTCBB, OTCQB or on the principal securities exchange or other
securities market on which the Common Stock is then being traded.

(b)      Conversion
Price During Major Announcements. Notwithstanding anything contained in Section 1.2(a) to the contrary, in the event the Borrower
(i) makes a public announcement that it intends to consolidate or merge with any other corporation (other than a merger in which
the Borrower is the surviving or continuing corporation and its capital stock is unchanged) or sell or transfer all or substantially
all of the assets of the Borrower or (ii) any person, group or entity (including the Borrower) publicly announces a tender offer
to purchase 50% or more of the Borrower’s Common Stock (or any other takeover scheme) (the date of the announcement referred
to in clause (i) or (ii) is hereinafter referred to as the “Announcement Date”), then the Conversion Price shall,
effective upon the Announcement Date and continuing through the Adjusted Conversion Price Termination Date (as defined below),
be equal to the lower of (x) the Conversion Price which would have been applicable for a Conversion occurring on the Announcement
Date and (y) the Conversion Price that would otherwise be in effect. From and after the Adjusted Conversion Price Termination
Date, the Conversion Price shall be determined as set forth in this Section 1.2(a). For purposes hereof, “Adjusted Conversion
Price Termination Date” shall mean, with respect to any proposed transaction or tender offer (or takeover scheme) for which
a public announcement as contemplated by this Section 1.2(b) has been made, the date upon which the Borrower (in the case of clause
(i) above) or the person, group or entity (in the case of clause (ii) above) consummates or publicly announces the termination
or abandonment of the proposed transaction or tender offer (or takeover scheme) which caused this Section 1.2(b) to become operative.


 


1.3Authorized
Shares. The Borrower covenants that during the period the conversion right exists, the Borrower will reserve from its authorized
and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of Common Stock
upon the full conversion of this Note issued pursuant to the Purchase Agreement. The Borrower is required at all times to have
authorized and reserved five times the number of shares that is actually issuable upon full conversion of the Note (based on the
Conversion Price of the Notes in effect from time to time) (the “Reserved Amount”). The Reserved Amount shall be increased
from time to time in accordance with the Borrower’s obligations pursuant to Section 3(d) of the Purchase Agreement. The
Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. In addition,
if the Borrower shall issue any securities or make any change to its capital structure which would change the number of shares
of Common Stock into which the Notes shall be convertible at the then current Conversion Price, the Borrower shall at the same
time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved,
free from preemptive rights, for conversion of the outstanding Notes. The Borrower (i) acknowledges that it will promptly instruct
its transfer agent to issue certificates for the Common Stock issuable upon conversion of this Note, and (ii) agrees that
its issuance of this Note 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 shares of Common Stock in accordance with the terms and
conditions of this Note.


 


If,
at any time the Borrower does not maintain the Reserved Amount it will be considered an Event of Default under Section 3.2 of
the Note.

1.4Method
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 5:00 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 (the “Deadline”),
provided however, for purposes of defining the three business day Deadline herein only, any Notice of Conversion received after
3:00 p.m., New York, New York time, shall be deemed to have been received on the following business day (and, solely in the case
of conversion of the entire unpaid principal amount hereof, surrender of this Note) in accordance with the terms hereof and the
Purchase Agreement.


 



    	5



    	 



    




 


(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 5:00 p.m., New York, New York time,
on such date.


 


(f)       Delivery
of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Common Stock issuable
upon conversion, provided the Borrower 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 commercially reasonable 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 At Custodian (“DWAC”) system.


 





(g)      Failure
to Deliver Common Stock Prior to Delivery 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, 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.


 






    	6



    	 



    

 


1.5Concerning
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 Purchase Agreement). Except as otherwise provided in the Purchase 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 reasonably accepted by the Borrower 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
Borrower 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 Regulation S, at the Deadline, it will be considered an Event of Default pursuant
to Section 3.2 of the Note.


 



    	7



    	 



    




 


1.6Effect
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.


 






    	8



    	 



    

 


(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.


  


(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 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.


 


1.7Trading
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 Purchase 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 4.99% of the total shares outstanding on the Closing Date (as defined
in the Purchase 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. 


 



    	9



    	 



    




 


1.8Status
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.

principal hereof or interest thereon at the Maturity Date specified in Section 3,1 hereof), 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 to150%
times the sum of (w) the then outstanding principal amount of this Note plus (x) accrued and unpaid interest

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.

4.3Amendments.
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 Purchase Agreement) as originally executed, or if later amended or supplemented, then as so amended
or supplemented.


 


4.4Assignability.
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.


 


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


 


4.6Governing
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 Massachusetts or in the federal courts located in the Commonwealth of Massachusetts.
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
with 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

4.7Certain
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.

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

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.


 






    	18



    	 



    




 


4.10Remedies.
The Borrower acknowledges that a breach by it of its obligations hereunder may 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, regardless of whether or not the breach has caused
irreparable harm to the Holder, 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.
