CONVERTIBLE PROMISSORY NOTE


 


FOR VALUE RECEIVED, MYDX,
INC., a Nevada corporation (hereinafter called the “Borrower”), hereby promises to pay to the order of CROWN
BRIDGE PARTNERS, LLC, a New York limited liability company, or registered assigns (the “Holder”) the principal
sum of $50,000.00 (the “Principal Amount”), together with interest at the rate of eight percent (8%) per annum, at
maturity or upon acceleration or otherwise, as set forth herein (the “Note”). The consideration to the Borrower for
this Note is $45,000.00 (the “Consideration”). At the closing, the outstanding principal amount under this Note shall
be $50,000.00, consisting of the Consideration plus the OID (as defined 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, as well as any accrued and
unpaid interest and other fees shall be due and payable. This Note may not be prepaid in whole or in part except as otherwise explicitly
set forth herein. Any amount of principal or interest on this Note, which is not paid by the Maturity Date, 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 the Borrower’s common stock
(the “Common Stock”) in accordance with the terms hereof) shall be made in lawful money of the United States of America.
All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written notice made in accordance
with the provisions of this Note. Whenever any amount expressed to be due by the terms of this Note is due on any day which is
not a business day, the same shall instead be due on the next succeeding day which is a business day and, in the case of any interest
payment date which is not the date on which this Note is paid in full, the extension of the due date thereof shall not be taken
into account for purposes of determining the amount of interest due on such date. As used in this Note, the term “business
day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the city of New York, New York
are authorized or required by law or executive order to remain closed.


 






     


     

    

 


This Note carries an original issue
discount of $5,000.00 (the “OID”), to cover the Holder’s legal fees, accounting fees, due diligence fees, monitoring,
and/or other transactional costs incurred in connection with the purchase and sale of the Note, which is included in the principal
balance of this Note. Thus, the purchase price of this Note shall be $45,000.00, computed as follows: the Principal Amount minus
the OID.


 


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 additional terms
shall apply to this Note:


 


Article
I. CONVERSION RIGHTS


 


1.1  
Conversion Right. The Holder shall have the right, at any time after the six (6) month anniversary of the Issue
Date, to convert all or any part of the outstanding and unpaid principal amount and accrued and unpaid interest of this Note into
fully paid and non-assessable shares of Common Stock, as such Common Stock exists on the Issue Date, or any shares of capital
stock or other securities of the Borrower into which such Common Stock shall hereafter be changed or reclassified at the conversion
price (the “Conversion Price”) determined as provided herein (a “Conversion”); provided, however,
that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon
conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other
than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes
or the unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise
analogous to the limitations contained herein) 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, 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.


 






    2


     

    

 


1.2  
Conversion Price.


 


(a)   
Calculation of Conversion Price. The Conversion Price shall be the Variable Conversion Price (as defined herein)
(subject, in each case, 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)(also subject to adjustment as further described herein). The "Variable Conversion
Price" shall mean 50% multiplied by the Market Price (as defined herein)(representing a discount rate of 50%). “Market
Price” means the lowest one (1) Trading Prices (as defined below) for the Common Stock during the twenty (20) Trading Day
period ending on the last complete Trading Day prior to the Conversion Date. “Trading Prices” means, for any security
as of any date, the lowest traded price on the Over-the-Counter Pink Marketplace, the OTC Markets, OTCQB, or applicable trading
market (the “OTCQB”) as reported by a reliable reporting service (“Reporting Service”) designated by the
Holder (i.e. www.Nasdaq.com) or, if the OTCQB is not the principal trading market for such security, on the principal securities
exchange or trading market where such security is listed or traded or, if the lowest intraday trading price of such security is
not available in any of the foregoing manners, the lowest intraday price of any market makers for such security that are quoted
on the OTC Markets. If the Trading Prices cannot be calculated for such security on such date in the manner provided above, the
Trading Prices shall be the fair market value as mutually determined by the Borrower and the Company. “Trading Day”
shall mean any day on which the Common Stock is tradable for any period on the OTCQB, or on the principal securities exchange or
other securities market on which the Common Stock is then being traded. If at any time while this Note is outstanding, the lowest
Trading Prices on the OTC Markets, OTCQB or other applicable principal trading market for the Common Stock is equal to or lower
than $0.10 for two consecutive Trading Days, then an additional discount of ten percent (10%) shall be factored into the Variable
Conversion Price until this Note is no longer outstanding (resulting in a discount rate of 60% assuming no other adjustments are
triggered hereunder). In the event that shares of the Borrower’s Common Stock are not deliverable via DWAC following the
conversion of any amount hereunder, an additional ten percent (10%) discount shall be factored into the Variable Conversion Price
until this Note is no longer outstanding (resulting in a discount rate of 60% assuming no other adjustments are triggered hereunder).


 






    3


     

    

 


1.3  
Authorized 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. The Borrower is required at all times to have authorized and reserved four
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 hereunder. 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 has irrevocably instructed 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.


 


1.4  
Method of Conversion.


 


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


 






    4


     

    

 


(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”)
(and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) in accordance with
the terms hereof.


 


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


 






    5


     

    

 


(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 best efforts to cause its transfer agent to electronically transmit
the Common Stock issuable upon conversion to the Holder by crediting the account of Holder’s Prime Broker with DTC through
its Deposit Withdrawal Agent Commission (“DWAC”) system.


 


(g)   
Failure to Deliver Common Stock Prior to Deadline. Without in any way limiting the Holder’s right to pursue
other remedies, including actual damages and/or equitable relief, the parties agree that if delivery of the Common Stock issuable
upon conversion of this Note is not delivered by the Deadline (other than a failure due to the circumstances described in Section
1.3 above, which failure shall be governed by such Section) the Borrower shall pay to the Holder $2,000 per day in cash, for each
day beyond the Deadline that the Borrower fails to deliver such Common Stock (unless such failure results from war, acts of terrorism,
an epidemic, or natural disaster). 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


     

    

 


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


 


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


 


The legend set forth above shall
be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer legend if (i) the Borrower
or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary for opinions of counsel
in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration
under the Act, which opinion shall be accepted by the 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 Holder 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


     

    

 


1.6  
Trading Market Limitations. Unless permitted by the applicable rules and regulations of the principal securities
market on which the Common Stock is then listed or traded, in no event shall the Borrower issue upon conversion of or otherwise
pursuant to this Note 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 currently outstanding, subject to equitable adjustment from time to time for stock splits,
stock dividends, combinations, capital reorganizations and similar events relating to the Common Stock occurring after the date
hereof. Once the Maximum Share Amount has been issued, if the Borrower fails to eliminate any prohibitions under applicable law
or the rules or regulations of any stock exchange, interdealer quotation system or other self-regulatory organization with jurisdiction
over the Borrower or any of its securities on the Borrower’s ability to issue shares of Common Stock in excess of the Maximum
Share Amount, in lieu of any further right to convert this Note, this will be considered an Event of Default under Section 3.3
of the Note.


 


1.7  
Status as Shareholder. Upon submission of a Notice of Conversion by a Holder, (i) the shares covered thereby (other
than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the
Reserved Amount or Maximum Share Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights
as a Holder of such converted portion of this Note shall cease and terminate, excepting only the right to receive certificates
for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because
of a failure by the Borrower to comply with the terms of this Note. Notwithstanding the foregoing, if a Holder has not received
certificates for all shares of Common Stock prior to the tenth (10th) business day after the expiration of the Deadline with respect
to a conversion of any portion of this Note for any reason, then (unless the Holder otherwise elects to retain its status as a
holder of Common Stock by so notifying the Borrower) the Holder shall regain the rights of a Holder of this Note with respect to
such unconverted portions of this Note and the Borrower shall, as soon as practicable, return such unconverted Note to the Holder
or, if the Note has not been surrendered, adjust its records to reflect that such portion of this Note has not been converted.
In all cases, the Holder shall retain all of its rights and remedies (including, without limitation, (i) the right to receive Conversion
Default Payments pursuant to Section 1.3 to the extent required thereby for such Conversion Default and any subsequent Conversion
Default and (ii) the right to have the Conversion Price with respect to subsequent conversions determined in accordance with Section
1.3) for the Borrower’s failure to convert this Note.

in the form of additional shares of Common Stock or (b) directly or indirectly or through any subsidiary make any other payment
or distribution in respect of its capital stock except for distributions pursuant to any shareholders’ rights plan which

of the Borrower or any warrants, rights or options to purchase or acquire any such shares.


 


2.3

without the Holder’s written consent, sell, lease, exchange (including but not limited to an exchange for assets of equal
or greater value) or otherwise dispose of any significant portion of its assets outside the ordinary course of business. 
Any consent to the disposition of any assets may be conditioned on a specified use of the proceeds of disposition.

default (each, an “Event of Default”) shall occur:


 


3.1

on this Note, whether at maturity, upon acceleration or otherwise, and such breach continues for a period of five (5) days.

Conversion and the Shares. The Borrower fails to reserve a sufficient amount of shares of common stock as required
under the terms of this Note (including Section 1.3 of this Note)(and such breach continues for a period of five (5) days), fails
to issue shares of Common Stock to the Holder (or announces or threatens in writing that it will not honor its obligation to do
so) upon exercise by the Holder of the conversion rights of the Holder in accordance with the terms of this Note, fails to transfer
or cause its transfer agent to transfer (issue) (electronically or in certificated form) shares of Common Stock issued to the Holder
upon conversion of or otherwise pursuant to this Note as and when required by this Note, the Borrower directs its transfer agent
not to transfer or delays, impairs, and/or hinders its transfer agent in transferring (or issuing) (electronically or in certificated
form) shares of Common Stock to be issued to the Holder upon conversion of or otherwise pursuant to this Note as and when required
by this Note, or fails to remove (or directs its transfer agent not to remove or impairs, delays, and/or hinders its transfer agent
from removing) any restrictive legend (or to withdraw any stop transfer instructions in respect thereof) on any shares of Common
Stock issued to the Holder upon conversion of or otherwise pursuant to this Note as and when required by this Note (or makes any
written announcement, statement or threat that it does not intend to honor the obligations described in this paragraph) and any
such failure shall continue uncured (or any written announcement, statement or threat not to honor its obligations shall not be
rescinded in writing) for two (2) business days after the Holder shall have delivered a Notice of Conversion. It is an obligation
of the Borrower to remain current in its 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 funds shall be paid by the Borrower to the Holder within five (5) business days of a demand from the Holder, either in
cash or as an addition to the balance of the Note, and such choice of payment method is at the discretion of the Borrower.


 


3.3

the Holder with respect to this Note.

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 a receiver or trustee shall otherwise be appointed.


 


3.6  
Judgments. Any money judgment, writ or similar process shall be entered or filed against the Borrower or any subsidiary
of the Borrower or any of its property or other assets for more than $100,000, and shall remain unvacated, unbonded or unstayed
for a period of twenty (20) days unless otherwise consented to by the Holder, which consent will not be unreasonably withheld.

to pay its debts as such debts become due, provided, however, that any disclosure of the Borrower’s ability to continue as
a “going concern” shall not be an admission that the Borrower cannot pay its debts as they become due.


 


3.12  Financial Statement Restatement. Any restatement of any financial statements filed by the Borrower with the SEC for
any date or period from two years prior to the Issue Date of this Note and until this Note is no longer outstanding, if the result
of such restatement would, by comparison to the unrestated financial statement, have constituted a material adverse effect on the
rights of the Holder with respect to this Note.


 


3.13  Replacement of Transfer Agent. In the event that the Borrower replaces its transfer agent, and the Borrower fails
to provide prior to the effective date of such replacement, a fully executed Irrevocable Transfer Agent Instructions (including
but not limited to the provision to irrevocably reserve shares of Common Stock in the Reserved Amount) signed by the successor

Upon the occurrence and during
the continuation of any Event of Default specified in Section 3.1 (solely with respect to failure to pay the principal hereof or
interest thereon when due at the Maturity Date), the Note shall become immediately due and payable and the Borrower shall pay to
the Holder, in full satisfaction of its obligations hereunder, an amount equal to the Default Sum (as defined herein).  Upon
the occurrence and during the continuation of any Event of Default specified in Sections 3.1 (solely with respect to failure to
pay the principal hereof or interest thereon when due on this Note or upon acceleration), 3.2, 3.3, 3.4, 3.5, 3.6, 3.8, 3.9, 3.10,
3.11, 3.12, 3.13, 3.14, 3.15, and/or 3.16 exercisable through the delivery of written notice to the Borrower by such Holders (the
“Default Notice”), and upon the occurrence of an Event of Default specified the remaining sections of Articles III
(other than failure to pay the principal hereof or interest thereon at the Maturity Date specified in Section 3,1 hereof), the
Note shall become immediately due and payable and the Borrower shall pay to the Holder, in full satisfaction of its obligations
hereunder, an amount equal to 150% multiplied by the then outstanding entire balance of the Note (including principal and
accrued and unpaid interest) plus Default Interest, if any, plus any amounts owed to the Holder pursuant to Sections
1.4(g) hereof (collectively, in the aggregate of all of the above, the “Default Sum”), and all other amounts payable
hereunder shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are expressly
waived, together with all costs, including, without limitation, legal fees and expenses, of collection, and the Holder shall be
entitled to exercise all other rights and remedies available at law or in equity. 


 


If the Borrower fails to pay the
Default Amount within five (5) business days of written notice that such amount is due and payable, then the Holder shall have
the right at any time, so long as the Borrower remains in default (and so long and to the extent that there are sufficient authorized
shares), to require the Borrower, upon written notice, to immediately issue, in lieu of the Default Amount, the number of shares
of Common Stock of the Borrower equal to the Default Amount divided by the Conversion Price then in effect, subject to issuance
in tranches due to the beneficial ownership limitations contained in this Note.

Article
IV. MISCELLANEOUS

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. Each transferee of this Note must be an “accredited investor”
(as defined in Rule 501(a) of the 1933 Act). Notwithstanding anything in this Note to the contrary, this Note may be pledged as
collateral in connection with a bona fide margin account or other lending arrangement.


 


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


 


4.6  
Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of New York
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 and/or federal courts of New York. 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

to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good
and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to

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  
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.






 


4.9  
 Prepayment. Notwithstanding anything to the contrary contained in this Note, the Borrower may prepay any amount
outstanding under this Note, during the initial 90 day period after the issuance of this Note, by making a payment to the Holder
of an amount in cash equal to 120% multiplied the amount that the Borrower is prepaying. Further, the Borrower may prepay any amount
outstanding under this Note, from the 91st day through the 180th day after the issuance of this Note, by
making a payment to the Holder of an amount in cash equal to 130% multiplied the amount that the Borrower is prepaying. The Borrower
may not prepay any amount outstanding under this Note after the 180th day after the issuance of this Note.
