PROMISSORY NOTE


 


FOR VALUE
RECEIVED, ELECTROMEDICAL TECHNOLOGIES, INC., a Delaware corporation (hereinafter called the “Borrower” or the “Company”)
(Trading Symbol: EMED), hereby promises to pay to the order of Mast Hill Fund, L.P., a Delaware limited partnership, or registered
assigns (the “Holder”), in the form of lawful money of the United States of America, the principal sum of $500,000.00, which
amount is the $450,000.00 actual amount of the purchase price (the “Consideration”) hereof plus an original issue discount
in the amount of $50,000.00 (the “OID”) (subject to adjustment herein) (the “Principal Amount”) and to pay interest
on the unpaid Principal Amount 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,
as further provided herein. The maturity date shall be twelve (12) months from the Issue Date (the “Maturity Date”), and is
the date upon which the Principal Sum, the OID, as well as any accrued and unpaid interest and other fees, shall be due and payable.


 


This Note may not be prepaid or repaid in whole or in part
except as otherwise explicitly set forth herein.


 


Any Principal
Amount or interest on this Note which is not paid when due shall bear interest at the rate of the lesser of (i) sixteen percent (16%)
per annum and (ii) the maximum amount permitted by law from the due date thereof until the same is paid (“Default Interest”).
Interest and Default Interest 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 shares of common stock, $0.00001 par value per share, of the Borrower (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.


 


Each capitalized
term used herein, and not otherwise defined, shall have the meaning ascribed thereto in that certain Securities Purchase Agreement, dated
as of the Issue Date, pursuant to which this Note was originally issued (the “Purchase Agreement”). 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. As used herein, the term “Trading Day”
means any day that shares of Common Stock are listed for trading or quotation on the Principal Market (as defined in the Purchase Agreement),
provided, however, that if the Common Stock is not then listed or quoted on any Principal Market, then any calendar day.


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 also apply to this Note:


 


ARTICLE I. CONVERSION RIGHTS


 


1.1
Conversion Right. The Holder shall have the right, on any calendar day, at any time on or following the date that is six (6) calendar
months after the Issue Date, to convert all or any portion of the then outstanding and unpaid Principal Amount and interest (including
any Default Interest) 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 notwithstanding
anything to the contrary contained herein, the a Holder shall not have the right to convert any portion of this Note, pursuant to Section
1 or otherwise, to the extent that after giving effect to such issuance after conversion as set forth on the applicable Notice of Conversion,
the Holder (together with the Holder’s affiliates (the “Affiliates”), and any other Persons (as defined below) acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would
beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number
of shares of Common Stock beneficially owned by the Holder and Attribution Parties shall include the number of shares of Common Stock
issuable upon conversion of this Note with respect to which such determination is being made, but shall exclude the number of shares of
Common Stock which would be issuable upon (i) conversion of the remaining, nonconverted portion of this Note beneficially owned by the
Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any
other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this
Section 1.1, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder, it being acknowledged by the Holder that the Holder is solely responsible for any schedules required to be filed
in accordance therewith. In addition, a determination as to any group status as contemplated above shall be determined in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 1.1, in determining
the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in
(A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public
announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares
of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and
in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the
Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported.
The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding at the time of
the respective calculation hereunder. “Person” and “Persons” means an individual, a limited liability company,
a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and any governmental entity or
any department or agency thereof. The limitations contained in this paragraph shall apply to a successor holder of this Note. The number
of Conversion Shares 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 or Borrower’s transfer agent 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 or Borrower’s transfer agent before 11:59 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 Rate to the Conversion Date, 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).


 






    2


     


    

 


 1.2 Conversion Price.




 


(a)  Calculation
of Conversion Price. The per share conversion price into which Principal Amount and interest (including any Default Interest)
under this Note shall be convertible into shares of Common Stock hereunder (the “Conversion Price”) shall equal $0.06.
If at any time the Conversion Price as determined hereunder for any conversion would be less than the par value of the Common Stock,
then at the sole discretion of the Holder, the Conversion Price hereunder may equal such par value for such conversion and the
Conversion Amount for such conversion may be increased to include Additional Principal, where “Additional Principal”
means such additional amount to be added to the Conversion Amount to the extent necessary to cause the number of conversion shares
issuable upon such conversion to equal the same number of conversion shares as would have been issued had the Conversion Price not
been adjusted by the Holder to the par value price. The Conversion Price is 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. Holder shall be
entitled to deduct $1,750.00 from the conversion amount in each Notice of Conversion to cover Holder’s fees associated with
each Notice of Conversion.


 


1.3  
Authorized and Reserved Shares. The Borrower covenants that at all times until the Note is satisfied in full, 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 a number of Conversion Shares equal to the greater of: (a) 16,666,666 shares of Common Stock or (b) the sum of (i) the
number of Conversion Shares issuable upon the full conversion of this Note (assuming no payment of Principal Amount or interest) at the
time of such calculation (taking into consideration any adjustments to the Conversion Price as provided in this Note) multiplied by
(ii) two (2) (the “Reserved Amount”). The Borrower represents that upon issuance, the Conversion Shares will be duly and validly
issued, fully paid and non-assessable. The Borrower (i) acknowledges that it has irrevocably instructed its transfer agent to issue certificates
for the Conversion Shares or instructions to have the Conversion Shares issued as contemplated by Section 1.4(f) hereof, 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 or cause the Company to electronically issue shares of Common Stock to execute and issue the necessary certificates for the
Conversion Shares or cause the Conversion Shares to be issued as contemplated by Section 1.4(f) hereof 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 (as defined in this Note) under this Note.


 


 1.4 Method of Conversion.




 


(a) 
Mechanics of Conversion. This Note may be converted by the Holder in whole or in part, on any calendar day, at any time
on or following the date that is six (6) calendar months after the Issue Date, by submitting to the Borrower or Borrower’s transfer
agent a Notice of Conversion (by facsimile, e-mail or other reasonable means of communication dispatched on the Conversion Date prior
to 11:59 p.m., New York, New York time). Any Notice of Conversion submitted after 11:59 p.m., New York, New York time, shall be deemed
to have been delivered and received on the next Trading Day.


 


(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 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 Holder
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.


 






    3


     


    

 


(d) 
Delivery of Common Stock Upon Conversion. Upon receipt by the Borrower or Borrower’s transfer agent 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 Conversion Shares (or cause the electronic delivery of the Conversion Shares as contemplated
by Section 1.4(f) hereof) within one (1) Trading Day after such receipt (the “Deadline”) (and, solely in the case of conversion
of the entire unpaid Principal Amount and interest (including any Default Interest) under this Note, surrender of this Note). If the Company
shall fail for any reason or for no reason to issue to the Holder on or prior to the Deadline a certificate for the number of Conversion
Shares or to which the Holder is entitled hereunder and register such Conversion Shares on the Company’s share register or to credit
the Holder’s balance account with DTC (as defined below) for such number of Conversion Shares to which the Holder is entitled upon
the Holder’s conversion of this Note (a “Conversion Failure”), then, in addition to all other remedies available to
the Holder, (i) the Company shall pay in cash to the Holder on each day after the Deadline and during such Conversion Failure an amount
equal to 2.0% of the product of (A) the sum of the number of Conversion Shares not issued to the Holder on or prior to the Deadline and
to which the Holder is entitled and (B) the closing sale price of the Common Stock on the Trading Day immediately preceding the last possible
date which the Company could have issued such Conversion Shares to the Holder without violating this Section 1.4(d); and (ii) the Holder,
upon written notice to the Company, may void all or any portion of such Notice of Conversion; provided that the voiding of all or any
portion of a Notice of Conversion shall not affect the Company’s obligations to make any payments which have accrued prior to the
date of such notice. In addition to the foregoing, if on or prior to the Deadline the Company shall fail to issue and deliver a certificate
to the Holder and register such Conversion Shares on the Company’s share register or credit the Holder’s balance account with
DTC for the number of Conversion Shares to which the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the
Company’s obligation pursuant to clause (ii) below, and if on or after such Trading Day the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable
upon such exercise that the Holder anticipated receiving from the Company, then the Company shall, within two (2) Trading Days after the
Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s
total purchase price (including brokerage commissions and other reasonable and customary out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate
(and to issue such Conversion Shares) or credit such Holder’s balance account with DTC for such Conversion Shares shall terminate,
or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Conversion Shares or credit
such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price
over the product of (A) such number of shares of Common Stock, times (B) the closing sales price of the Common Stock on the date of exercise.
Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without
limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates
representing the Conversion Shares (or to electronically deliver such Conversion Shares) upon the conversion of this Note as required
pursuant to the terms hereof.


 


(e)   Obligation
of Borrower to Deliver Common Stock. At the time that the Holder submits the Notice of Conversion to the Borrower or
Borrower’s transfer agent, the Holder shall be deemed to be the holder of record of the Conversion Shares issuable upon such
conversion, the outstanding Principal Amount and the amount of accrued and unpaid interest (including any Default Interest) under
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 the Conversion
Shares (or cause the electronic delivery of the Conversion Shares as contemplated by Section 1.4(f) hereof) 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 sent to
the Borrower or Borrower’s transfer agent before 11:59 p.m., New York, New York time, on such date.


 






    4


     


    

 


(f)  
Delivery of Conversion Shares by Electronic Transfer. In lieu of delivering physical certificates representing the Conversion
Shares issuable upon conversion hereof, provided the Borrower is participating in the Depository Trust Company (“DTC”) Fast
Automated Securities Transfer or Deposit/Withdrawal at Custodian programs, 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 Conversion Shares issuable upon conversion hereof to the Holder by crediting the account of Holder’s Prime Broker with
DTC through its Deposit Withdrawal Agent Commission system.


 


1.5  
Concerning the Shares. The Conversion Shares 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 1933 Act or (ii) the Borrower or its transfer agent
shall have been furnished with an opinion of counsel (which opinion shall be the Legal Counsel Opinion (as defined in the Purchase Agreement))
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, Rule 144A, Regulation S, or other applicable exemption, 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 Conversion Shares have
been registered under the 1933 Act or otherwise may be sold pursuant to Rule 144, Rule 144A, Regulation S, or other applicable exemption
without any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for
the Conversion Shares 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 MAY BE THE LEGAL COUNSEL OPINION (AS DEFINED IN THE PURCHASE AGREEMENT)), IN A GENERALLY ACCEPTABLE
FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144, RULE 144A, REGULATION S UNDER SAID ACT,
OR OTHER APPLICABLE EXEMPTION. 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 Company shall issue to the Holder a certificate for the applicable Conversion Shares
without such legend upon which it is stamped or (as requested by the Holder) issue the applicable Conversion Shares by electronic delivery
by crediting the account of such holder’s broker with DTC, if, unless otherwise required by applicable state securities laws: (a)
such Conversion Shares are registered for sale under an effective registration statement filed under the 1933 Act or otherwise may be
sold pursuant to Rule 144, Rule 144A, Regulation S, or other applicable exemption without any restriction as to the number of securities
as of a particular date that can then be immediately sold, or (b) the Company or the Holder provides the Legal Counsel Opinion (as contemplated
by and in accordance with Section 4(m) of the Purchase Agreement) to the effect that a public sale or transfer of such Conversion Shares
may be made without registration under the 1933 Act, which opinion shall be accepted by the Company so that the sale or transfer is effected.
The Company shall be responsible for the fees of its transfer agent and all DTC fees associated with any such issuance. The Holder agrees
to sell all Conversion Shares, including those represented by a certificate(s) from which the legend has been removed, in compliance
with applicable prospectus delivery requirements, if any. In the event that the Company does not accept the opinion of counsel provided
by the Holder with respect to the transfer of Conversion Shares pursuant to an exemption from registration, such as Rule 144, Rule 144A,
Regulation S, or other applicable exemption, at the Deadline, notwithstanding that the conditions of Rule 144, Rule 144A, Regulation
S, or other applicable exemption, as applicable, have been met, it will be considered an Event of Default under this Note.


 






    5


     


    

 


 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, 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 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 (defined in Section 3.19) 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 this Note, 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 effectuate any transaction described in this Section 1.6(b) unless (a) it first gives, to the extent practicable, at least 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.


 


(d)  
Purchase Rights. If, at any time when all or any portion of this Note is 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.


 






    6


     


    

 


(e)    Dilutive
Issuance. If the Borrower, at any time while this Note or any amounts due hereunder are outstanding, issues, sells or grants (or
has issued, sold or granted as of the Issue Date, as the case may be) any option to purchase, or sells or grants any right to
reprice, or otherwise disposes of, or issues (or has sold or issued, as the case may be, or announces any sale, grant or any option
to purchase or other disposition), any Common Stock or other securities convertible into, exercisable for, or otherwise entitle any
person or entity the right to acquire, shares of Common Stock (including, without limitation, upon conversion of this Note, and any
convertible notes or warrants outstanding as of or following the Issue Date), in each or any case at an effective price per share
that is lower than the then Conversion Price (such lower price, the “Base Conversion Price” and such issuances,
collectively, a “Dilutive Issuance”) (it being agreed that if the holder of the Common Stock or other securities so
issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or
exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be
entitled to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance
shall be deemed to have occurred for less than the Conversion Price on such date of the Dilutive Issuance), then the Conversion
Price shall be reduced, at the option of the Holder, to a price equal to the Base Conversion Price. Such adjustment shall be made
whenever such Common Stock or other securities are issued. By way of example, and for the avoidance of doubt, if the Company issues
a convertible promissory note (including but not limited to a Variable Rate Transaction), and the holder of such convertible
promissory note has the right to convert it into Common Stock at an effective price per share that is lower than the then Conversion
Price (including but not limited to a conversion price with a discount that varies with the trading prices of or quotations for the
Common Stock), then the Holder has the right to reduce the Conversion Price to such Base Conversion Price (including but not limited
to a conversion price with a discount that varies with the trading prices of or quotations for the Common Stock) in perpetuity
regardless of whether the holder of such convertible promissory note ever effectuated a conversion at the Base Conversion Price.
Notwithstanding the foregoing, no adjustment will be made under this Section 1.6(e) in respect of an Exempt Issuance. In the event
of an issuance of securities involving multiple tranches or closings, any adjustment pursuant to this Section 1.6(e) shall be
calculated as if all such securities were issued at the initial closing. For the avoidance of doubt, the Holder shall be entitled to
utilize the Base Conversion Price with respect to a Dilutive Issuance, even if the Dilutive Issuance occurs prior to the date that
the Holder is entitled to convert this Note.


 


An “Exempt
Issuance” shall mean the issuance of (a) shares of Common Stock or other securities to officers or directors of the Company pursuant
to any stock or option or similar equity incentive plan duly adopted for such purpose, by a majority of the non-employee members of the
Company’s Board of Directors or a majority of the members of a committee of non-employee directors established for such purpose
in a manner which is consistent with the Company’s prior business practices; (b) securities issued pursuant to a merger, consolidation,
acquisition or similar business combination approved by a majority of the disinterested directors of the Company, provided that any such
issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company
or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits
in addition to the investment of funds, but shall not include a transaction in which the Company is issuing securities primarily for the
purpose of raising capital or to an entity whose primary business is investing in securities; (c) securities issued pursuant to any equipment
loan or leasing arrangement, real property leasing arrangement or debt financing from a bank or similar financial institution approved
by a majority of the disinterested directors of the Company; or (d) securities issued with respect to which the Holder waives its rights
in writing under this Section 1.6(e).


 


(f)    
Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the
events described in Section 1.6 of this Note, the Borrower shall, at its expense and within one (1) calendar day after the occurrence
of each respective adjustment or readjustment of the Conversion Price, compute such adjustment or readjustment and prepare and furnish
to the Holder a certificate setting forth (i) the Conversion Price in effect at such time based upon the Dilutive Issuance, (ii) 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, (iii) the detailed facts upon which such adjustment or readjustment is based, and (iv) copies of the documentation (including
but not limited to relevant transaction documents) that evidences the adjustment or readjustment. In addition, the Borrower shall, within
one (1) calendar day after each written request from the Holder, furnish to such Holder a like certificate setting forth (i) the Conversion
Price in effect at such time based upon the Dilutive Issuance, (ii) 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, (iii) the detailed facts upon which such adjustment
or readjustment is based, and (iv) copies of the documentation (including but not limited to relevant transaction documents) that evidences
the adjustment or readjustment. For the avoidance of doubt, each adjustment or readjustment of the Conversion Price as a result of the
events described in Section 1.6 of this Note shall occur without any action by the Holder and regardless of whether the Borrower complied
with the notification provisions in Section 1.6 of this Note.

1.7  
[Intentionally Omitted].


 


1.8   
Status as Shareholder. Upon submission of a Notice of Conversion by a Holder, (i) the Conversion Shares covered thereby
(other than the Conversion 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 for the Borrower’s failure to convert this Note.


 


1.9  
Prepayment. At any time prior to the date that an Event of Default occurs under this Note (the “Prepayment Period”),
the Borrower shall have the right, exercisable on three (3) Trading Days prior written notice to the Holder of the Note, to prepay the
outstanding Principal Amount and interest then due under this Note in accordance with this Section 1.9. Any notice of prepayment hereunder
(an “Optional Prepayment Notice”) shall be delivered to the Holder of the Note at its registered addresses and shall state:
(1) that the Borrower is exercising its right to prepay the Note, and (2) the date of prepayment which shall be three (3) Trading Days
from the date of the Optional Prepayment Notice (the “Optional Prepayment Date”). The Holder shall have the right, at all
times prior to the actual receipt of the full prepayment amount on the Optional Prepayment Date, to instead convert all or any portion
of the Note pursuant to the terms of this Note, including the amount of this Note to be prepaid by the Borrower in accordance with this
Section 1.9, provided, however, that the Conversion Date is on or following the date that is six (6) calendar months after the Issue Date.
On the Optional Prepayment Date, the Borrower shall make payment of the amounts designated below to or upon the order of the Holder as
specified by the Holder in writing to the Borrower. If the Borrower exercises its right to prepay the Note in accordance with this Section
1.9, the Borrower shall make payment to the Holder of an amount in cash equal to the sum of: (w) 100% multiplied by the Principal Amount
then outstanding plus (x) accrued and unpaid interest on the Principal Amount to the Optional Prepayment Date plus (y) $750.00
to reimburse Holder for administrative fees.


 


If the Borrower delivers an
Optional Prepayment Notice and fails to pay the applicable prepayment amount due to the Holder of the Note as provided in this Section
1.9, then the Borrower shall forever forfeit its right to prepay any part of the Note pursuant to this Section 1.9.


 


1.10  
Repayment from Proceeds. If, at any time prior to the full repayment or full conversion of all amounts owed under this Note,
the Company receives cash proceeds from any source or series of related or unrelated sources, including but not limited to, from payments
from customers, the issuance of equity or debt, the conversion of outstanding warrants of the Borrower, the issuance of securities pursuant
to an equity line of credit of the Borrower or the sale of assets, the Borrower shall, within one (1) business day of Borrower’s
receipt of such proceeds, inform the Holder of or publicly disclose such receipt, following which the Holder shall have the right in its
sole discretion to require the Borrower to immediately apply up to 40% of such proceeds to repay all or any portion of the outstanding
Principal Amount and interest (including any Default Interest) then due under this Note (provided, however, that the aforementioned reference
to 40% shall be reduced to 25% with respect to the initial $500,000 of gross proceeds received by the Company solely pursuant to an equity
line of credit). Failure of the Borrower to comply with this provision shall constitute an Event of Default.

Trading Days after the Holder shall have delivered a Notice of Conversion, and/or (v) fails to remain current in its obligations to its
transfer agent (including but not limited to payment obligations to its transfer agent). It shall be an Event of Default of this Note,
if a conversion of this Note is delayed, hindered or frustrated due to a balance owed by the Borrower to its transfer agent. If at the
option of the Holder, the Holder advances any funds to the Borrower’s transfer agent in order to process a conversion, such advanced

3.3

with the passage of time will have) a material adverse effect on the rights of the Holder with respect to this Note or the Purchase Agreement.


 


3.5    
Receiver or Trustee. The Borrower or any subsidiary of the Borrower shall make an assignment for the benefit of creditors,
or apply for or consent to the appointment of a receiver or trustee for it or for a substantial part of its property or business, or such

or other assets which are necessary to conduct its business (whether now or in the future).

provisions of this Note. The Holder shall be entitled to exercise all other rights and remedies available at law or in equity.


 


ARTICLE IV. MISCELLANEOUS


 


4.1  
Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder 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 privileges. All rights and remedies of the Holder existing hereunder are cumulative
to, and not exclusive of, any rights or remedies otherwise available.


 


4.2

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 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. The Borrower shall not assign this Note or any rights or obligations hereunder without the prior written
consent of the Holder. The Holder may assign its rights hereunder to any “accredited investor” (as defined in Rule
501(a) of the 1933 Act) in a private transaction from the Holder or to any of its “affiliates”, as that term is defined
under the 1934 Act, without the consent of the Borrower. 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. The Holder and any assignee, by
acceptance of this Note, acknowledge and agree that 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.


 






    12


     


    

 


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; Venue; Attorney’s Fees. This Note shall be governed by and construed in accordance with the laws of
the State of Delaware without regard to principles of conflicts of laws. Any action brought by either party against the other concerning
the transactions contemplated by this Note or any other agreement, certificate, instrument or document contemplated hereby shall be brought
only in the state courts located in the Commonwealth of Massachusetts or federal courts located in the Commonwealth of Massachusetts.
The Borrower hereby irrevocably waives 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 HEREBY IRREVOCABLY WAIVES
ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR
ARISING OUT OF THIS NOTE OR ANY TRANSACTIONS CONTEMPLATED HEREBY. 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 Note or any other agreement, certificate,
instrument or document contemplated hereby or thereby 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 Note 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. The prevailing party in any action or dispute brought in connection with
this the Note or any other agreement, certificate, instrument or document contemplated hereby or thereby shall be entitled to recover
from the other party its reasonable attorney’s fees and costs.


 


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  
Purchase Agreement. The Company and the Holder shall be bound by the applicable terms of the Purchase Agreement and the
documents entered into in connection herewith and therewith.


 


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 change in control 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.


 






    13


     


    

 


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.


 


4.11 
Construction; Headings. This Note shall be deemed to be jointly drafted by the Company and all the Holder and shall not
be construed against any person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part
of, or affect the interpretation of, this Note.


 


4.12 
Usury. To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever
claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at
any time hereafter in force, in connection with any action or proceeding that may be brought by the Holder in order to enforce any right
or remedy under this Note. Notwithstanding any provision to the contrary contained in this Note, it is expressly agreed and provided that
the total liability of the Company under this Note for payments which under the applicable law are in the nature of interest shall not
exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”), and, without limiting the foregoing,
in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums which under the applicable
law in the nature of interest that the Company may be obligated to pay under this Note exceed such Maximum Rate. It is agreed that if
the maximum contract rate of interest allowed by applicable law and applicable to this Note is increased or decreased by statute or any
official governmental action subsequent to the Issue Date, the new maximum contract rate of interest allowed by law will be the Maximum
Rate applicable to this Note from the effective date thereof forward, unless such application is precluded by applicable law. If under
any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to the Holder with respect to indebtedness
evidenced by this the Note, such excess shall be applied by the Holder to the unpaid principal balance of any such indebtedness or be

4.13  
Severability. In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule
of law (including any judicial ruling), 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 this Note.


 


4.14   
Terms of Future Financings. So long as this Note is outstanding, upon any issuance by the Borrower or any of its subsidiaries
of any security, or amendment to a security that was originally issued before the Issue Date, with any term that the Holder reasonably
believes is more favorable to the holder of such security or with a term in favor of the holder of such security that the Holder reasonably
believes was not similarly provided to the Holder in this Note, then (i) the Borrower shall notify the Holder of such additional or more
favorable term within one (1) business day of the issuance and/or amendment (as applicable) of the respective security, and (ii) such
term, at Holder’s option, shall become a part of the transaction documents with the Holder (regardless of whether the Borrower complied
with the notification provision of this Section 4.14). The types of terms contained in another security that may be more favorable to
the holder of such security include, but are not limited to, terms addressing prepayment rate, interest rates, and original issue discounts.

4.15    Dispute
Resolution. In the case of a dispute as to the determination of the Conversion Price, Conversion Amount, any prepayment amount
or Default Amount, Issue, Closing or Maturity Date, the closing bid price, or fair market value (as the case may be) or the
arithmetic calculation of the Conversion Price or the applicable prepayment amount(s) (as the case may be), the Borrower or the
Holder shall submit the disputed determinations or arithmetic calculations via facsimile (i) within one (1) Trading Day after
receipt of the applicable notice giving rise to such dispute to the Borrower or the Holder or (ii) if no notice gave rise to such
dispute, at any time after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Borrower are
unable to agree upon such determination or calculation within one (1) Trading Day of such disputed determination or arithmetic
calculation (as the case may be) being submitted to the Borrower or the Holder, then the Borrower shall, within one (1) Trading Day,
submit (a) the disputed determination of the Conversion Price, the closing bid price, the or fair market value (as the case may be)
to an independent, reputable investment bank selected by the Borrower and approved by the Holder or (b) the disputed arithmetic
calculation of the Conversion Price, Conversion Amount, any prepayment amount or Default Amount, to an independent, outside
accountant selected by the Holder that is reasonably acceptable to the Borrower. The Borrower shall cause at its expense the
investment bank or the accountant to perform the determinations or calculations and notify the Borrower and the Holder of the
results no later than one (1) Trading Day from the time it receives such disputed determinations or calculations. Such investment
bank’s or accountant’s determination or calculation shall be binding upon all parties absent demonstrable error.


 


4.16   
Right of First Refusal. If at any time while this Note is outstanding, the Borrower has a bona fide offer of capital or
financing from any 3rd party, that the Borrower intends to act upon, then the Borrower must first offer such opportunity to the Holder
to provide such capital or financing to the Borrower on the same terms as each respective 3rd party’s terms. Should the Holder be
unwilling or unable to provide such capital or financing to the Borrower within five (5) Trading Days from Holder’s receipt of written
notice of the offer (the “Offer Notice”) from the Borrower, then the Borrower may obtain such capital or financing from that
respective 3rd party upon the exact same terms and conditions offered by the Borrower to the Holder, which transaction must be completed
within 30 days after the date of the Offer Notice. If the Borrower does not receive the capital or financing from the respective 3rd party
within 30 days after the date of the respective Offer Notice, then the Borrower must again offer the capital or financing opportunity
to the Holder as described above, and the process detailed above shall be repeated. The Offer Notice must be sent via electronic mail
to admin@masthillfund.com.
