Section 4.     Conversion.


 


a)     Voluntary
Conversion. This Note shall be convertible, in whole or in part, into shares of Common Stock at the option of the Holder,
at any time and from time to time. The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the
form of which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein the
principal amount of this Note to be converted and accrued interest as of the date on which such conversion shall be effected (such
date, the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion
Date shall be the date that such Notice of Conversion is deemed delivered hereunder. No ink-original Notice of Conversion shall
be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be
required. To effect conversions hereunder, the Holder shall not be required to physically surrender this Note to the Company
unless the entire principal amount of this Note, plus all accrued and unpaid interest thereon, has been so converted. Conversions
hereunder shall have the effect of lowering the outstanding principal amount of this Note in an amount equal to the applicable
conversion. The Holder and the Company shall maintain records showing the principal amount(s) converted and the date of such conversion(s).
The Company may deliver an objection to any Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion.
In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of
manifest error. 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 may
be less than the amount stated on the face hereof.


 






    	 	6	 



     


    

 


b)     Conversion
Price. The conversion price in effect on any Conversion Date shall be equal to $4.95 (the “Conversion Price”).
All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification
or similar transaction that proportionately decreases or increases the Common Stock during such measuring period. Nothing herein
shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 6 hereof and the
Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from
seeking to enforce damages pursuant to any other Section hereof or under applicable law.


 


c)     Mechanics of Conversion.




 


i.     Conversion Shares Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion
hereunder shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note to be converted
by (y) the Conversion Price.


 


ii.    Delivery of Certificate Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the “Share
Delivery Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates
representing the Conversion Shares which, on or after the earlier of (i) the six month anniversary of the Original Issue Date or

in cash) and (C) a bank check in the amount of the Make-Whole Amount. All certificate or certificates required to be delivered
by the Company under this Section 4(c) shall be delivered electronically through the Depository Trust Company or another established
clearing corporation performing similar functions. If the Conversion Date is prior to the earlier of (i) the six month anniversary
of the Original Issue Date or (ii) the Effective Date, then the Conversion Shares shall bear a restrictive legend in the following
form, as appropriate:


 






    	 	7	 



     


    

 


“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.”


 


iii.     Failure to Deliver Certificates. If, in the case of any Notice of Conversion, such certificate or certificates are not delivered
to or as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice
to the Company at any time on or before its receipt of such certificate or certificates, to rescind such Conversion, in which event
the Company shall promptly return to the Holder any original Note delivered to the Company and the Holder shall promptly return
to the Company the Common Stock certificates issued to such Holder pursuant to the rescinded Conversion Notice.


 


iv.     Obligation Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares
upon conversion of this Note in accordance with the terms hereof are absolute and unconditional, irrespective of any action or
inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment
against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation
of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation
of the Company to the Holder in connection with the issuance of such Conversion Shares; provided, however, that such
delivery shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the event
the Holder of this Note shall elect to convert any or all of the outstanding principal amount hereof, the Company may not refuse
conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation
of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and or enjoining
conversion of all or part of this Note shall have been sought and obtained, and the Company posts a surety bond for the benefit
of the Holder in the amount of 150% of the outstanding principal amount of this Note, which is subject to the injunction, which
bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which
shall be payable to the Holder to the extent it obtains judgment. In the absence of such injunction, the Company shall issue Conversion
Shares or, if applicable, cash, upon a properly noticed conversion. If the Company fails for any reason to deliver to the Holder
such certificate or certificates pursuant to Section 4(c)(ii) by the Share Delivery Date, the Company shall pay to the Holder,
in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount being converted, $10 per Trading Day (increasing
to $20 per Trading Day on the fifth (5th) Trading Day after such liquidated damages begin to accrue) for each Trading
Day after such Share Delivery Date until such certificates are delivered or Holder rescinds such conversion. Nothing herein shall
limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 6 hereof for the Company’s
failure to deliver Conversion Shares within the period specified herein and the Holder shall have the right to pursue all remedies
available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive
relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section
hereof or under applicable law.

v.     Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available
to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery
Date pursuant to Section 4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase
(in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion
relating to such Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in
addition to any other remedies available to or elected by the Holder) the amount, if any, by which (x) the Holder’s total
purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate
number of shares of Common Stock that the Holder was entitled to receive from the conversion at issue multiplied by (2) the actual
sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and
(B) at the option of the Holder, either reissue (if surrendered) this Note in a principal amount equal to the principal amount
of the attempted conversion (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number of shares
of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under Section 4(c)(ii).
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an
attempted conversion of this Note with respect to which the actual sale price of the Conversion Shares (including any brokerage
commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence,
the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts
payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein
shall limit a 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 shares of Common Stock upon conversion of this Note as required pursuant to the terms hereof.


 


vi.     [Reserved].


 


vii.     Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this
Note. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Company
shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Conversion Price or round up to the next whole share.


 


viii.     Transfer Taxes and Expenses. The issuance of certificates for shares of the Common Stock on conversion of this Note shall
be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue
or delivery of such certificates, provided that, the Company shall not be required to pay any tax that may be payable in respect
of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the
Holder of this Note so converted and the Company shall not be required to issue or deliver such certificates unless or until the
Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established
to the satisfaction of the Company that such tax has been paid. The Company shall pay all Transfer Agent fees required for same-day
processing of any Notice of Conversion.

Section 5.     Certain Adjustments.


 


a)     Stock Dividends and Stock Splits. If the Company, at any time while this Note is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion
of, or payment of interest on, the Note), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii)
combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv)
issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company, then the
Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding
any treasury shares of the Company) outstanding immediately before such event, and of which the denominator shall be the number
of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall
become effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 


b)     Subsequent Equity Sales. If, at any time while this Note is outstanding, the Company or any Subsidiary, as applicable, sells
or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any
sale, grant or any option to purchase or other disposition), any Common Stock or Common Stock Equivalents entitling any Person
to acquire shares of Common Stock at an effective price per share that is lower (after accounting for stock splits and similar
adjustments) than the then Conversion Price (such lower price, the “Base Conversion Price” and such issuances,
collectively, a “Dilutive Issuance”) (if the holder of the Common Stock or Common Stock Equivalents 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 to equal the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents
are issued. Notwithstanding the foregoing, no adjustment will be made under this Section 5(b) in respect of an Exempt Issuance.
If the Company enters into a Variable Rate Transaction, despite the prohibition set forth in the Securities Purchase Agreement,
the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible conversion price at
which such securities may be converted or exercised. The Company shall notify the Holder in writing, no later than the Trading
Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 5(b), indicating therein the
applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the
“Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance
Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number
of Conversion Shares based upon the Base Conversion Price on or after the date of such Dilutive Issuance, regardless of whether
the Holder accurately refers to the Base Conversion Price in the Notice of Conversion.


 






    	 	10	 



     


    

 


c)     [Reserved].


 


d)     Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 5(a) above, if at any time the Company grants,
issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without regard to
any limitations on exercise hereof) 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 shares of Common Stock are to be determined
for the grant, issue or sale of such Purchase Rights.


 


e)     Pro Rata Distributions. During such time as this Note is outstanding, if the Company shall declare or make any dividend
or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of
capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by
way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a
"Distribution"), at any time after the issuance of this Note, then, in each such case, the Holder shall be entitled
to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the
number of shares of Common Stock acquirable upon complete exercise of this Note (without regard to any limitations on exercise
hereof) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date
as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution.

f)     Fundamental Transaction. If, at any time while this Note is outstanding, (i) the Company, directly or indirectly, in one
or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, (v) the Company, directly or indirectly, in one or more related
transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the
outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or
party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other
business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion of this Note,
the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately
prior to the occurrence of such Fundamental Transaction, the number of shares of Common Stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Note
is convertible immediately prior to such Fundamental Transaction. For purposes of any such conversion, the determination of the
Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Conversion
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any conversion of this Note following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the
obligations of the Company under this Note in accordance with the provisions of this Section 5(f) pursuant to written agreements
in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such
Fundamental Transaction and shall, at the option of the holder of this Note, deliver to the Holder in exchange for this Note a
security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Note which
is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent
to the shares of Common Stock acquirable and receivable upon conversion of this Note (without regard to any limitations on the
conversion of this Note) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price
hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to
such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion
price being for the purpose of protecting the economic value of this Note immediately prior to the consummation of such Fundamental
Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Note and the other Transaction Documents referring to the “Company” shall refer
instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Note and the other Transaction Documents with the same effect as if such Successor Entity had been named
as the Company herein.

g)     Calculations. All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share,
as the case may be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as
of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Company) issued
and outstanding.


 


h)     Notice to the Holder.


 


i.     Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the
Company shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth
a brief statement of the facts requiring such adjustment.


 


ii.     Notice to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever
form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (C) the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party,
any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common
Stock is converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Note, and shall cause to be delivered to the Holder at its last address
as it shall appear upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record
to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date
as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share
exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the
validity of the corporate action required to be specified in such notice. To the extent that any notice provided hereunder constitutes,
or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously
file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to convert this
Note during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice
except as may otherwise be expressly set forth herein.

annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights as a holder of the Note until such
time, if any, as the Holder receives full payment pursuant to this Section 6(b). No such rescission or annulment shall affect any
subsequent Event of Default or impair any right consequent thereon.

Section 7.     Mandatory
Redemption or Conversion.


 


If a public
offering is consummated while this Note is outstanding (the “Public Offering”) that results in the Company obtaining
financing of seven million dollars ($7,000,000) or greater, the Holder, at its sole option may: (a) redeem, in cash, the balance
of principal and accrued interest to be paid from the proceeds of the Public Offering; or (b) convert the balance of principal
and accrued interest into Common Stock at the Conversion Price. In such event, the Holder shall execute a lock-up agreement, in
a form reasonably satisfactory to Holder, to not sell the Common Stock commencing at the time of the roadshow for the Public Offering
and ending three (3) months after the Public Offering closes.


 


Section 8.     Miscellaneous.

on this Note at the time, place, and rate, and in the coin or currency, herein prescribed. This Note is a direct debt obligation
of the Company. This Note ranks pari passu with all other Notes now or hereafter issued under the terms set forth
herein.


 






    	 	17	 



     


    

 


c)     Lost or Mutilated Note. If this Note shall be mutilated, lost, stolen or destroyed, the Company shall execute and deliver,
in exchange and substitution for and upon cancellation of a mutilated Note, or in lieu of or in substitution for a lost, stolen
or destroyed Note, a new Note for the principal amount of this Note so mutilated, lost, stolen or destroyed, but only upon receipt
of evidence of such loss, theft or destruction of such Note, and of the ownership hereof, reasonably satisfactory to the Company.


 


d)     Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense
of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective
Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for
such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such
suit, action or proceeding 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

by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Note or the transactions
contemplated hereby. If any party shall commence an action or proceeding to enforce any provisions of this Note, then the prevailing
party in such action or proceeding shall be reimbursed by the other party for its attorneys' fees and other costs and expenses
incurred in the investigation, preparation and prosecution of such action or proceeding.


 


e)     Waiver. Any waiver by the Company or the Holder of a breach of any provision of this Note shall not operate as or be construed
to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Company
or the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver
or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note on any
other occasion. Any waiver by the Company or the Holder must be in writing.


 






    	 	18	 



     


    

 


f)     Severability. If any provision of this Note is invalid, illegal or unenforceable, the balance of this Note shall remain
in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other
Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable
law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of
interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall not at
any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury
law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on
this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or
the performance of this Note, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage
of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.


 


g)     Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief.  The remedies provided in this Note
shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents
at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit
the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of
this Note.  The Company covenants to the Holder that there shall be no characterization concerning this instrument other than
as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the
computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject
to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company
therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other
available remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing
economic loss and without any bond or other security being required. The Company shall provide all information and documentation
to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and
conditions of this Note.


 


h)     Next Business Day. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day.


 


i)     Headings. The headings contained herein are for convenience only, do not constitute a part of this Note and shall not be
deemed to limit or affect any of the provisions hereof.


 


j)     Secured Obligation. The obligations of the Company under this Note are secured by all assets of the Company pursuant to
the Deferred Salary Security Agreement, dated as of July 1, 2016 between the Company and Holder, as amended from time-to-time.
