PROMISSORY NOTE

USD$[__________]April [__], 2022

 

For
value received, 4Front Ventures Corp., a corporation amalgamated under the laws of the Province of British Columbia, Canada (“4Front”
or “Maker”), promises to pay to the order of the Persons listed on Schedule A attached hereto (collectively,
the “Holders” and each individually a “Holder”), or to each such Holder’s permitted transferees
or assigns, in lawful money of the United States of America and in immediately available funds, the aggregate principal amount of $[__________],
in accordance with the allocations set forth on Schedule A attached hereto, together with interest thereon calculated as provided
below, in accordance with, and subject to, the provisions of this Promissory Note (this “Note”).

1.       Merger
Agreement. This Note is being executed in connection with the transactions contemplated by that certain Agreement and Plan of Merger,
dated as of March 30, 2022 (as the same may be amended from time to time, the “Merger Agreement”), by and among (a)
4Front, (b) Island Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of 4Front, (c) Island Global Holdings, Inc., a
California corporation, and (d) Navy Capital SR LLC, a Delaware limited liability company, solely in its capacity as the representative
of the Island Securityholders (as defined in the Merger Agreement), and is subject to the provisions thereof. Initially capitalized terms
used but not defined in this Note have the meanings assigned to such terms in the Merger Agreement.

2.       Maturity
Date; Prepayments. The outstanding principal amount of this Note, all accrued but unpaid interest thereon, and all other amounts payable
under this Note shall be due and payable on the date that is fifty-four (54) months after the date of this Note (the “Maturity
Date”). Subject to the terms of the Merger Agreement, Maker may prepay its obligations under this Note in whole or in part,
at any time or from time to time, without penalty or premium, by paying the outstanding principal amount together with all accrued but
unpaid interest thereon.

3.       PIK
Interest. Except as otherwise provided herein, the outstanding principal amount of this Note shall bear interest at an annual rate
of six percent (6%) from the date hereof until such time as Maker’s obligations under this Note are paid in full, whether at maturity,
upon acceleration, by prepayment or otherwise. If not previously paid, all accrued but unpaid interest due and payable pursuant to this
Note shall be paid on the Maturity Date. All computations of interest shall be made on the basis of a year of 365/366 days, as the case
may be, and the actual number of days elapsed.

4.       Payment
Mechanics. All payments of interest and principal shall be made in lawful money of the United States of America on the date on which
such payment is due by wire transfer of immediately available funds to each Holder’s account at a bank specified by such Holder
in writing to Maker from time to time. All payments made hereunder shall be applied first, to the payment of any fees or charges outstanding
hereunder, second, to accrued but unpaid interest and third, to the payment of the principal amount outstanding under this Note. Whenever
any payment to be made hereunder shall be due on a day that is not a Business Day, such payment shall be made on the next succeeding Business
Day and such extension will be taken into account in calculating the amount of interest payable under this Note. For the avoidance of
doubt, the intent of the Maker and the Holder is that the amounts payable under this Note to each Holder shall be the same amount as would
be payable to each Holder if each Holder had a separate Note evidence its indebtedness and each Holder shall be permitted to make a claim
against Maker to the same extent.

    	 

    	 

    

 

 

5.       Right
of Offset. Maker shall be entitled to offset, pro rata to each Holder in accordance with the allocation set forth on Schedule A,
against the outstanding principal amount hereunder any amounts owed to Maker or any other 4Front Indemnitees by Holders pursuant to Section
9 of the Merger Agreement. It being acknowledged and agreed that Maker’s right to so offset the outstanding principal balance shall
not permit it to offset such amounts to the extent it could make draw under the Navy LOC therefor.

any of its properties or assets may be bound); or (iii) constitute a default under any material agreement or contract by which 4Front
may be bound.

(f)       This
Note is a valid, legal and binding obligation of 4Front, enforceable against 4Front in accordance with its terms, except as enforceability

rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at Law).

7.       Events
of Default; Remedies. The existence or occurrence of one or more than one of the following events shall constitute an “Event
of Default” under this Note:

specified in clause (a) above, and such failure continues for thirty (30) days after written notice to Maker;

(d)       the

8.       Subordination.

by, Maker, including principal, interest and all other amounts payable thereunder, which restricts, limits, or prohibits payments under
this Note (the “Senior Debt” and any lender of any Senior Debt, a “Senior Creditor”). Subject to
the following sentence, until all Senior Debt has been paid in full, Maker will not pay and Holders will not accept any payment on the
Note other than payments expressly permitted below (the “Permitted Subordinated Debt Payments”), and Holders shall
not be entitled to enforce or receive payment thereof (other than Permitted Subordinated Debt Payments) until all Senior Debt has been
paid in full. Maker shall make the payments described in Sections 1 and 2 above, unless at the time of such payment, an
event of default (or words of similar meaning, giving Senior Creditor the right to accelerate the Senior Debt and declare the same immediately
due and payable) under any Senior Debt or other credit documents (as defined therein) related to such Senior Debt exists or would be caused
by such payment(a “Senior Default”), and such Senior Default shall not have been waived in writing or cured in accordance
with the applicable Senior Debt. Any period of time that any applicable Permitted Subordinated Debt Payment shall have been blocked from
being paid in accordance with this Section 8 shall be deemed a “Payment Blockage Period”. Interest shall continue
to accrue in accordance with the terms of this Note during any Payment Blockage Period. Upon expiration of any Payment Blockage Period
and so long as no other Payment Blockage Period is in effect, Maker may make or resume making (and Holders may receive and retain) any
and all Permitted Subordinated Debt Payments (or portion thereof).

    3 

     

    

 

 

(b)       At
any time and from time to time, without any Holder’s consent or notice to Holders, and without liability to Holders and without
releasing or impairing any of the rights of any Senior Creditor against Holders or any of Holders’ obligations hereunder, any Senior
Creditor may take security for Senior Debt; release, exchange, or subordinate any security for Senior Debt; release any person obligated
on Senior Debt; modify, amend, restate, extend or waive compliance with any agreement, instrument or other document relating to Senior
Debt, including, without limitation, increasing Senior Debt; apply sums paid by any party to the Senior Debt in any order or manner as
determined by the applicable Senior Creditor, subject to the terms of the Senior Debt; grant any adjustment, extension, indulgence, or
forbearance to, or compromise with, any person liable for Senior Debt; neglect, delay, omit, fail, or refuse to take or prosecute any
action for collection of any Senior Debt, or to foreclose any collateral or take or prosecute any action on any agreement securing any
Senior Debt. Holders and Maker agree that (i) no modifications to this Note may be made without the written consent of each Senior Creditor
and (ii) no guaranties of this Note may be granted; provided, that, no such consent shall be required (except during the pendency
of an Action with respect to the Maker or its assets) to extend the Maturity Date of this Note, to lower the interest rate payable under
this Note or to reflect any Holder’s assignment of all or a portion of the Note (to the extent such assignment is consummated in
compliance with the terms hereof).

(c)       Each
Holder covenants and agrees to execute and deliver such customary documents and instruments as may be reasonably requested by any Senior
Creditor to evidence the subordination of this Note as contemplated herein, including, without limitation, executing a separate subordination
agreement (a “Subordination Agreement”) which includes the subordination terms reflected herein and any other provisions
customarily included in agreements governing such relationships that do not alter or expand such Holder’s or Maker’s rights
or obligations under this Note or such Holder’s rights or obligations under the Subordination Agreement.

(d)       In
the event of any conflict between any term, covenant, or condition of this Note and any term, covenant or condition of the Subordination
Agreement, the provisions of the Subordination Agreement shall control and govern.

9.       Waiver
of Presentment. Maker, on behalf of itself and its successors and assigns, hereby waives diligence, presentment, protest and demand
and notice of protest, demand, dishonor and nonpayment of this Note, and expressly agrees that this Note, or any payment hereunder, may
be extended from time to time and that any Holder may accept security for this Note or release security for this Note, all without in
any way affecting the liability of Maker hereunder.

10.       Amendment
and Waiver. Except as otherwise expressly provided herein, the provisions of this Note may be amended and Maker may take any action
herein prohibited, or omit to perform any act herein required to be performed by it, only if Maker has obtained the prior written consent
of the Majority Holders (as hereinafter defined). As used herein, the “Majority Holders” shall mean at least a majority
of the aggregate principal amount of the this Note then outstanding, it being acknowledged and agreed that the Majority Holders and Maker
may amend all Notes then outstanding on an aggregate basis.

such further documents and do such further acts and things as such Holder may reasonably request in order to effect the purpose of this
Note.

12.       Replacement.

of any such mutilation, upon the surrender of this Note to Maker, Maker shall execute and deliver, in lieu thereof, a new Note representing
the same rights represented by such lost, stolen, destroyed or mutilated Note and dated so that there will be no loss of interest on such
Note. Any Note in lieu of which any such new Note has been so executed and delivered by Maker shall not be deemed to be an outstanding
Note for any purpose.

13.       Severability.
Any provision of this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability
in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

14.       No
Waiver. Holders shall not by any act, delay, omission or otherwise be deemed to have waived any of their respective rights or remedies
hereunder, and no waiver shall be valid unless in writing, signed by the affected Holder (or an authorized agent or representative of
such Holder), and then only to the extent therein set forth. A waiver by any Holder of any right or remedy hereunder on any one occasion
shall not be construed as a bar to any right or remedy which such Holder would otherwise have on any future occasion. No failure to exercise
or any delay in exercising on the part of any Holder, any right, power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege.

All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to

amount of this Note at the rate of 4% per annum, on each Conversion Date (as to the principal amount then being redeemed) and on the Maturity
Date (each such date, an “Interest Payment Date”) (if any Interest Payment Date is not a Trading Day, then the applicable
payment shall be due on the next succeeding Trading Day), in cash or, at the Company’s option, in duly authorized, validly issued,
fully paid and non-assessable shares of Common Stock at the Interest Conversion Rate (the dollar amount to be paid in shares, the “Interest
Share Amount”) or a combination thereof; provided, however, that payment in shares of Common Stock may only occur if (i) all of
the Equity Conditions have been met during the 10 Trading Days immediately prior to the applicable Interest Payment Date (the “Interest
Notice Period”) and through and including the date such shares of Common Stock are actually issued to the Holder, (ii) the Company
shall have given the Holder notice in accordance with the notice requirements set forth below and (iii) as to such Interest Payment Date,
prior to such Interest Notice Period (but not more than five Trading Days prior to the commencement of such Interest Notice Period), the
Company shall have delivered to the Holder’s account with The Depository Trust Company a number of shares of Common Stock to be
applied against such Interest Share Amount equal to the quotient of the applicable Interest Share Amount divided by then Conversion Price
assuming for such purposes that the Interest Payment Date is the Trading Day immediately prior to the commencement of the Interest Notice
Period (the “Interest Conversion Shares”).

 

(b) Company’s

in cash, shares of Common Stock or a combination thereof shall be at the sole discretion of the Company. Prior to the commencement of
any Interest Notice Period, the Company shall deliver to the Holder a written notice of its election to pay interest hereunder on the
applicable Interest Payment Date either in cash, shares of Common Stock or a combination thereof and the Interest Share Amount as to the
applicable Interest Payment Date, provided that the Company may indicate in such notice that the election contained in such notice shall

(whether specific to an Interest Payment Date or continuous) shall be irrevocable as to such Interest Payment Date. Subject to the aforementioned
conditions, failure to timely deliver such written notice to the Holder shall be deemed an election by the Company to pay the interest
on such Interest Payment Date in cash. At any time, the Company delivers a notice to the Holder of its election to pay the interest in
shares of Common Stock, the Company shall timely file a prospectus supplement pursuant to Rule 424 disclosing such election. The aggregate
number of shares of Common Stock otherwise issuable to the Holder on an Interest Payment Date shall be reduced by the number of Interest
Conversion Shares previously issued to the Holder in connection with such Interest Payment Date.

 

    5

     

    

 

(c) Interest
Calculations. Interest shall be calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall
accrue daily commencing on the Original Issue Date until payment in full of the outstanding principal, together with all accrued and unpaid
interest, liquidated damages and other amounts which may become due hereunder, has been made. Payment of interest in shares of Common
Stock (other than the Interest Conversion Shares issued prior to an Interest Notice Period) shall otherwise occur pursuant to Section
4(c)(ii) herein and, solely for purposes of the payment of interest in shares, the Interest Payment Date shall be deemed the Conversion
Date. Interest shall cease to accrue with respect to any principal amount converted, provided that, the Company actually delivers the
Conversion Shares within the time period required by Section 4(c)(ii) herein. Interest hereunder will be paid to the Person in whose name
this Note is registered on the records of the Company regarding registration and transfers of this Note (the “Note Register”).
Except as otherwise provided herein, if at any time the Company pays interest partially in cash and partially in shares of Common Stock
to the Note Holder, then such payment of cash shall be distributed ratably among the holders of the then-outstanding Notes based on their
(or their predecessor’s) initial purchases of Notes pursuant to the Purchase Agreement.

 

(d) Late
Fee. All overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at an interest rate equal to 18% per annum
(the “Late Fees”) which shall accrue daily from the date such interest is due hereunder through and including the date of
actual payment in full..

 

(e) Prepayment.
The Company shall have the option to prepay this Note in full (including all unpaid interest, liquidated damages and any other amounts
then owing to the Holder) at any time after the Original Issue Date and prior to the Maturity Date at an amount equal to the Prepayment
Amount; provided, however, that the Company shall provide written notice to the Holder at least 5 Trading Days prior to the date on which
the Note shall be prepaid (such payment date, the “Prepayment Date”). The Holder may convert, pursuant to Section 4(a), any
amounts due under this Note subject to a prepayment notice at any time prior to the date that the Prepayment Amount (for the avoidance
of doubt, inclusive of all accrued but unpaid interest, liquidated damages and any other amounts then owing to the Holder) is paid in
full.

  

Section 3. Registration of Transfers
and Exchanges.

 

(a) Different Denominations.
This Note is exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by the
Holder surrendering the same. No service charge or other fees will be payable for such registration of transfer or exchange.

 

(b) Investor Representations.
This Note has been issued subject to certain investment representations of the original Holder set forth in the Purchase Agreement and
may be transferred or exchanged only in compliance with the Purchase Agreement and applicable federal and state securities laws and regulations.

 

(c) Reliance on Note
Register. Prior to due presentment for transfer to the Company of this Note, the Company and any agent of the Company may treat the
Person in whose name this Note is duly registered on the Note Register as the owner hereof for the purpose of receiving payment as herein
provided and for all other purposes, whether or not this Note is overdue, and neither the Company nor any such agent shall be affected
by notice to the contrary.

Section 4. Conversion.

 

(a) Conversion. Beginning
on the six month anniversary of the Original Issuance Date until this Note is no longer outstanding, this Note shall be convertible, in
whole or in part, at any time, and from time to time, into Conversion Shares at the option of the Holder. 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 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 and other charges, 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 in each conversion, the date of each conversion, and the Conversion
Price in effect at the time of each conversion. The Company may deliver an objection to any Notice of Conversion within two Trading Days
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. 

 

(b) Conversion
Price. The “Conversion Price” shall be $0.0125 per share, subject to any adjustments contained in this Note. If
the average Closing Price during any 10 consecutive Trading Day period beginning and ending during the 60 Day Effectiveness Period (the
“Average Closing Price”) is below the Conversion Price than the conversion price shall be reduced to such Average Closing
Price but in no event less than $0.00875. All such Conversion Price determinations are to be appropriately adjusted for any stock
dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common
Stock.

 

(c) Mechanics of Conversion
or Repayment.

 

(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 in effect
at the time of such conversion.

 

(ii) Delivery of Certificate
Upon Conversion. Not later than three Trading Days after each Conversion Date (the “Share Delivery Date”), the Company
shall deliver, or cause to be delivered, to the Holder (A) the Conversion Shares which, on or after the earlier of (i) the six month anniversary
of the Original Issue Date or (ii) the effective date of the Registration Statement, shall be free of restrictive legends and trading
restrictions (other than those which may then be required by the Purchase Agreement or those required by Rule 144(i)) representing the
number of Conversion Shares being acquired upon the conversion of this Note (including, if the Company has given continuous notice pursuant
to Section 2(b) for payment of interest in shares of Common Stock at least 10 Trading Days prior to the date on which the Notice of Conversion
is delivered to the Company, shares of Common Stock representing the payment of accrued interest otherwise determined pursuant to Section
2(a) but assuming that the Interest Notice Period is the 10 Trading Days period immediately prior to the date on which the Notice of Conversion
is delivered to the Company and excluding for such issuance the condition that the Company deliver Interest Conversion Shares as to such
interest payment prior to the commencement of the Interest Notice Period) and (B) a bank check or wire transfer in the amount of accrued
and unpaid interest (if the Company has elected or is required to pay accrued interest in cash). On or after the earlier of (i) the six-month
anniversary of the Original Issue Date or (ii) the effective date of the Registration Statement, the Company shall deliver any Conversion
Shares required to be delivered by the Company under this Section 4(c) electronically through the Depository Trust Company or another
established clearing corporation performing similar functions.

 

(iii) Failure to Deliver
Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares 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 Conversion Shares, to rescind such conversion, in which event the Company shall promptly return to the Holder
any original Note delivered to the Company.

 

    7

     

    

 

(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. 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 accordance with Section 4.1(f) of the Purchase Agreement. The exercise of any such rights shall not prohibit the Holder
from seeking to collect damages under this Note, the Purchase Agreement or under applicable law.

 

(v) Compensation for Buy-In
on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the Holder, (a) if the
Company fails for any reason to deliver to the Holder such Conversion Shares on or before the date that is seven (7) Trading Days after
the respective Share Delivery Date, and (b) if after the respective Share Delivery Date, (i) the Holder was required by its brokerage
firm to purchase (in an open market transaction or otherwise) or (ii) 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 pay to such Holder, in cash, an
amount equal to the excess of such Holder’s total purchase price (including brokerage commissions and other reasonable out-of-pocket
expenses, if any) for the shares of Common Stock so purchased (including brokerage commissions and other reasonable out-of-pocket expenses,
if any) (the “Buy-In Price”) over the product of (A) such number of shares of Common Stock that the Company was required to
deliver to such Holder by the Share Delivery Date multiplied by (B) the highest volume weighted average price of the Common Stock on any
Trading Day during the period commencing on the respective Share Delivery Date and ending on the date of the Company’s actual delivery
of the shares of Common Stock that Holder was entitled to receive upon conversion relating to such Share Delivery Date. Nothing herein
or therein 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 Conversion
Shares upon conversion of this Note as required pursuant to the terms hereof.

 

(vi) 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 the fraction
to the next whole share as long as it does not violate the Beneficial Ownership Limitation in which case the fractional share shall be
disregarded.to the next whole share.

 

(vii) Transfer Taxes and
Expenses. The issuance of Conversion Shares 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. The Company shall pay all Transfer
Agent fees required for processing of any Notice of Conversion in accordance with the terms of the Note and all fees to the Depository
Trust Company (or another established clearing corporation performing similar functions) required for electronic delivery of the Conversion
Shares in accordance with the terms of the Note.

 

(viii) Attorneys’
Fees etc. The Company shall (A) pay up to $500 per opinion to the law firm of the Holder’s choice (not to exceed a total of
ten (10) opinions in the aggregate) in connection with the conversion of the Note, (B) cause its attorneys to promptly provide any reliance
opinion to the Transfer Agent, and (C) pay the Holder the sums required under Section 2(c)(iv).

 

    8

     

    

 

(d) Holder’s
Conversion Limitations. The Company shall not effect any conversion of this Note, and a Holder shall not have the right to convert
any portion of this Note, to the extent that after giving effect to the conversion set forth on the applicable Notice of Conversion, the
Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with the Holder or any of the Holder’s
Affiliates) 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 its Affiliates 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 are issuable upon (i) conversion of the remaining, unconverted principal amount of this Note beneficially
owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation,
any other Notes or the Warrants) beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence,
for purposes of this Section 4(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the
rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 4(d) applies, the determination
of whether this Note is convertible (in relation to other securities owned by the Holder together with any Affiliates) and of which principal
amount of this Note is convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be
deemed to be the Holder’s determination of whether this Note may be converted (in relation to other securities owned by the Holder
together with any Affiliates) and which principal amount of this Note is convertible, in each case subject to the Beneficial Ownership
Limitation. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a
Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this Section 4(d) and the Company shall
have no obligation to verify or confirm the accuracy of such determination. 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 4(d), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding
shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed
with the SEC, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the
Company or the Company’s 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 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 immediately after giving effect to the issuance of shares of Common Stock issuable
upon conversion of this Note held by the Holder. The Holder, upon not less than 61 days’ prior notice to the Company, may increase
the Beneficial Ownership Limitation provisions of this Section 4(d) to 9.99% of the number of shares of Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon conversion of this Note held by the Holder. In all events, the provisions
of this Section 4(d) shall continue to apply. Any such increase or decrease will not be effective until the 61st day after such notice
is delivered to the Company. The Holder may also decrease the Beneficial Ownership Limitation provisions of this Section 4(d) solely with
respect to the Holder’s Note at any time, which decrease shall be effectively immediately upon delivery of notice to the Company.
The Beneficial Ownership Limitation provisions of this Section 4(d) shall be construed and implemented in a manner otherwise than in strict
conformity with the terms of this Section 4(d) to correct any portion which may be defective or inconsistent with the intended Beneficial
Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation.
The limitations contained in this Section 4(d) shall apply to a successor holder of this Note.

 

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, (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 5(a)
shall become effective immediately after the record date for the determination of shareholders 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.

 

    9

     

    

 

(b) Subsequent Equity
Sales.

 

(1) At any time this
Note or any amounts accrued and payable thereunder remain 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 than the Conversion Price then in effect (such lower price, the “Base Conversion Price”
and each such issuance or announcement a “Dilutive Issuance”), then the Conversion Price shall be immediately reduced to equal
the Base Conversion Price. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued.

 

(2) If any Common
Stock Equivalent is amended or adjusted, and such price as so amended shall be less than the Conversion Price in effect at the time of
such amendment or adjustment, then the Conversion Price shall be adjusted upon each such issuance or amendment as provided in this Section
5(b). In case any Common Stock Equivalent is issued in connection with the issue or sale of other securities of the Company, together
comprising one integrated transaction, (x) the Common Stock Equivalents will be deemed to have been issued for the Option Value of such
Common Stock Equivalents and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued
or sold for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company
pursuant to the terms of such other securities of the Company, less (II) the Option Value. If any shares of Common Stock or Common Stock
Equivalents are issued or sold or deemed to have been issued or sold for cash, the amount of such consideration received by the Company
will be deemed to be the net amount received by the Company therefor. If any shares of Common Stock or Common Stock Equivalents are issued
or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration,
except where such consideration consists of publicly traded securities, in which case the amount of consideration received by the Company
will be the average VWAP of such public traded securities for the ten days prior to the date of receipt. If any shares of Common Stock
or Common Stock Equivalents are issued to the owners of the non-surviving entity in connection with any merger in which the Company is
the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business
of the non-surviving entity as is attributable to such shares of Common Stock or Common Stock Equivalents, as the case may be.

  

(3) If the holder
of Common Stock or Common Stock Equivalents outstanding on the Original Issue Date or issued after the Original Issuance Date (including
but not limited to any Variable Rate Transaction) 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
then in effect, such issuance shall be deemed to have occurred for less than the Conversion Price on such date that the holder of Common
Stock or Common Stock Equivalents is entitled to receive shares of Common Stock at an effective price per share that is lower than the
Conversion Price then in effect, and such issuance shall be deemed to be a Dilutive Issuance.

 

(4) [Intentionally
Omitted].

 

(5) 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.

 

(6) The provisions
of this Section 5(b) shall apply each time a Dilutive Issuance occurs after the Original Issue Date for so long as the Note or any amounts
accrued and payable thereunder remain outstanding, but any adjustment of the Conversion Price pursuant to this Section 5(b) shall be downward
only.

 

    10

     

    

 

(7) The provisions of
this Section 5(b) shall not apply to Exempt Issuances.

 

(c) 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, 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 conversion hereof, including without
limitation, the Beneficial Ownership Limitation) 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 (provided, however, to the extent that the Holder’s right to
participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall
not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result
of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time,
if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

(d) 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 or warrants to acquire its assets, or subscribe for or purchase any security other than Common Stock, 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 conversion of this Note (without regard to any limitations on exercise hereof, including
without limitation, the Beneficial Ownership Limitation) 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 (provided, however, to the extent that the Holder’s right to participate in any such Distribution would
result in the Holder exceeding the Beneficial Ownership Limitation with respect to the Company or any other publicly-traded corporation
subject to Section 13(d) of the Exchange Act, then the Holder shall not be entitled to participate in such Distribution to such extent
(or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such
Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation with respect to the Company or any other publicly-traded corporation subject
to Section 13(d) of the Exchange Act).

(e) Fundamental Transaction.
(1) 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 (without regard to any limitation on the conversion of this Note),
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
(without regard to any limitation on the conversion of this Note). 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 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 not effect a Fundamental Transaction unless it gives the Holder at least 10 Trading Days prior
notice together with sufficient details so the Holder can make an informed decision as to whether it elects to accept the Alternative
Consideration. If a public announcement of the Fundamental Transaction has not been made, the notice to the Holder may not be given until
the Company files a Form 8-K or other report disclosing the Fundamental Transaction. (2) Notwithstanding anything to the contrary, provided
that the Warrant Shares are not registered under an effective registration statement in accordance with the Registration Rights Agreement,
in the event of a Fundamental Transaction that is (x) an all cash transaction, (y) a “Rule 13e-3 transaction” as defined in
Rule 13e-3 under the Exchange Act, or (z) a Fundamental Transaction involving a person or entity not traded on a national securities exchange
or trading market (with such exchange or market including, without limitation, the Nasdaq Global Select Trading Market, the Nasdaq Global
Market, or the Nasdaq Capital Market, the New York Stock Exchange, Inc., the NYSE American or any market operated by the OTC Markets,
Inc.), the Company or any Successor Entity (as defined below) shall, at the Holder’s option, concurrently with the consummation
of the Fundamental Transaction, purchase this Note from the Holder by paying to the Holder the higher of (i) an amount of cash equal to
the Black Scholes Value of the outstanding principal of this Note on the date of the consummation of such Fundamental Transaction, or
(ii) the product of (a) the number of Conversion Shares issuable upon full conversion of this Note (without regard to any limitation on
conversion of this Note) and (b) the positive difference between the cash per share paid in such Fundamental Transaction minus the then
in effect Conversion Price. (3) If Section 5(e)(1) and (2) are not applicable, 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 and the other Transaction Documents in accordance with the provisions of this Section 5(e) 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, 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. Notwithstanding anything in this Section 5(e), an Exempt Issuance (as defined
in the Purchase Agreement) shall not be deemed a Fundamental Transaction.

 

(f) 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.

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 its Common Stock,
(B) the Company shall declare a special nonrecurring cash dividend on or a redemption of its Common Stock, (C) the Company shall authorize
the granting to all holders of its 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 shareholders of the Company shall be required in connection with any reclassification
of its 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 its 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,

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

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 its 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 (as determined in good faith by the Company),
the Company or its successor shall simultaneously file such notice with the SEC pursuant to a Current Report on Form 8-K. If the Company
does not simultaneously file the required Form 8-K, the Holder shall be entitled penalties in accordance with Section 4.6 of the Purchase

(f) Waiver. Any waiver

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

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.

 

    17

     

    

 

(h) 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 would 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.

 

(i) Senior Obligation.
So long as the Company shall have any obligation under this Note, the Company shall not incur or suffer to exist or guarantee any unsecured
Indebtedness that is senior to or pari passu with (in priority of payment and performance) the Company’s obligations under this
Note.

  

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

 

(j) 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.
