G.          Section
4 of the Note is hereby added as follows:

 

“Section 4.          Conversion.

 

a)          Voluntary
Conversion. At any time after the Original Issue Date until this Note is no longer outstanding, this Note shall be convertible,
in whole and not in part, into that number of Common Shares (or an equivalent thereof) as is equal to the quotient obtained by
dividing (i) the aggregate principal amount of this Note (plus any accrued but unpaid interest) by (ii) the Conversion Price, at
the option of the Holder, at any time and from time to time. The Conversion Price in effect on a Conversion Date (as defined below)
in connection with the Company’s initial public offering (the “IPO”) shall be equal to the lesser of (A)
(i) $4.50 or (B) (i) the highest price per Common Share sold in the IPO, multiplied by (ii) 40%; and on any other Conversion Date,
the Conversion Price shall be $4.50. 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
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.
To effect conversions hereunder, the Holder shall be required to physically surrender this Note to the Company. The Company may
deliver an objection to any Notice of Conversion within two (2) Business Days of delivery of such Notice of Conversion.

 

b)          Mandatory
Conversion. In the event that the Company completes an IPO, the aggregate principal amount of this Note (plus any accrued but
unpaid interest) shall be converted, automatically and without any further action on the part of the Holder, the Company or any
other Person, into that number of Common Shares (or an equivalent thereof) as is equal to the quotient obtained by dividing (i)
the aggregate principal amount of this Note (plus any accrued but unpaid interest) by (ii) the Conversion Price.

 

c)          Conversion
Price. The Conversion Price in effect on a Conversion Date in connection with the IPO shall be equal to the lesser of
(A) (i) $4.50 or (B) (i) the highest price per Common Share sold in the IPO, multiplied by (ii) 40%; and on any other Conversion
Date, the Conversion Price shall be $4.50. In the event that the Company (i) issued a dividend on Common Shares payable in Common
Shares or any Common Share Equivalents (which, for avoidance of doubt, shall not include any Common Shares issued by the Company
upon conversion of, or payment of interest on, the Notes), (ii) subdivides outstanding Common Shares into a larger number of Common
Shares, (iii) combines (including by way of a reverse split) outstanding Common Shares into a smaller number of Common Shares or
(iv) issues, in the event of a reclassification of Common Shares, any Common Shares of the Company, then the Conversion Price shall
be adjusted by multiplying the Conversion Price by a fraction of which the numerator shall be the number of Common Shares outstanding
immediately before such event, and of which the denominator shall be the number of Common Shares outstanding immediately after
such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination
of members entitled to receive such distribution and shall become effective immediately after the effective date in the case of
a subdivision, combination or re-classification.

 

    	 	5	 

     

    

  

d)          Adjustments
for Reorganization, Merger, Consolidation or Sales of Assets. If at any time or from time to time after the issuance date of
this Note there shall be a capital reorganization of the Company (other than by way of a stock split or combination of shares or
stock dividends or distributions, or a reclassification, exchange or substitution of shares), or a merger or consolidation of the
Company with or into another corporation where the holders of the Company’s outstanding voting securities prior to such merger
or consolidation do not own over 50% of the outstanding voting securities of the merged or consolidated entity, immediately after
such merger or consolidation, or the sale of all or substantially all of the Company’s properties or assets to any other
person (an “Organic Change”), then as a part of such Organic Change an appropriate revision to the conversion
price shall be made if necessary and provision shall be made if necessary (by adjustments of the conversion price or otherwise)
so that, upon any subsequent conversion of this Note, the Holder shall have the right to receive, in lieu of Conversion Shares,
the kind and amount of shares of stock and other securities or property of the Company or any successor corporation resulting from
the Organic Change. In any such case, appropriate adjustment shall be made in the application of the provisions of Section 4(a)
with respect to the rights of the Holder after the Organic Change to the end that the provisions of Section 4(a) (including any
adjustment in the conversion price then in effect and the number of shares of stock or other securities deliverable upon conversion
of this Note) shall be applied after that event in as nearly an equivalent manner as may be practicable.

 

e)          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. The Company shall promptly deliver, or cause to be delivered, to the Holder a certificate or
certificates representing the Conversion Shares representing the number of Conversion Shares being acquired upon the conversion
of this Note (the “Share Delivery Date”).

 

iii.         Failure
to Deliver Certificates. If, in the case of a Notice of Conversion in connection with the IPO, 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 Share certificates issued to such Holder pursuant to the rescinded Notice of Conversion.

 

    	 	6	 

     

    

  

iv.         Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue 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. Nothing herein shall limit a Holder’s right
to pursue actual damages or declare an Event of Default pursuant to Section 5 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 at IPO. 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(d)(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, Common Shares 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 Shares so purchased exceeds (y) the product of (1) the aggregate number
of Common Shares 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 Common Shares that
would have been issued if the Company had timely complied with its delivery requirements under Section 4(d)(ii). For example, if
the Holder purchases Common Shares 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 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 Common
Shares upon conversion of this Note as required pursuant to the terms hereof.

 

    	 	7	 

     

    

  

vi.         Fractional
Common Shares. No fractional Common 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 Common Share.”

 

H.         Exhibit
A attached hereto is hereby attached to the Note as Annex A and added immediately following the last page of the Note.

 

Section 3.          Issuance
of Warrant to Holder. In consideration for Holder agreeing to extend the Maturity Date, the Company shall issue to the Holder
the Warrant, in substantially the form attached hereto as Exhibit B.

 

Section 4.          Pricing
of IPO. In the event that an IPO of the Company has not priced before July 25, 2018, and such failure to price the initial
public offering results in the Company to be unable fulfill its obligations hereunder or causes the Holder to feel insecure about
its position as a secured lender, then the Holder shall, between 8:00pm ET and 11:59pm ET on July 24, 2018, or any time thereafter
provide notice to the Company of its intention to declare an Event of Default under the Note.

 

Section 5.          Ratifications;
Inconsistent Provisions; Severability. Except as otherwise expressly provided herein the Note is, and shall continue to be,
in full force and effect and is hereby ratified and confirmed in all respects, except that on and after the Effective Date, all
references in the Note to “this Note”, as well as “hereto”, “hereof”, “hereunder”
or words of like import referring to the Note, as applicable, shall mean the Note, as applicable and as amended by this Amendment.
Notwithstanding the foregoing to the contrary, to the extent that there is any inconsistency between the provisions of the Agreement,
the Note or the other Transaction Documents, and this Amendment, the provisions of this Amendment shall control and be binding.
In the event and to the extent that any provision of this Amendment shall be held invalid or unenforceable, such invalidity or
unenforceability shall not affect the validity or enforceability of any other provisions of this Amendment, all of which shall
remain fully enforceable as set forth herein.

 

Section 6.          Acknowledgments.
The Holder acknowledges and agrees that the Company is not in default under the Note or any of the related Transaction Documents.
As such, this Amendment represents the compromise between the Parties and is not intended as an admission of any default, liability,
fault, claim, wrongdoing, or the like of or by the Company. The Company explicitly denies any and all liability with regard to
any potential claims that could be made by the Holder and the Holder acknowledges the foregoing.

and agrees that such service shall constitute good and sufficient service of process and notice thereof.  Nothing contained

shall be null and void in the event that any default hereunder is not reasonably cured in the timeframe called for under the Note
and all amendments thereto or the Holder and the Company otherwise agree in writing to such other modifications or extensions.

is one of a series of Warrants to purchase Common Stock issued pursuant to the Series G Documents.

 

Section 1.           Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Series G 20% Original Issue Discount

		Section 2.	Exercise.

 

a)           Exercise
of Warrant. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section
2(e), exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or
after the Original Issue Date and on or before the Termination Date by delivery to the Company (or such other office or agency
of the Company as the Company may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise form annexed hereto and within three (3)
trading days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate
Exercise Price of the Common Stock thereby purchased by wire transfer to an account designated by the Company or cashier’s
check drawn on a United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below.
If the amount of payment received by the Company is less than the aggregate Exercise Price of the Common Stock being purchased,
the Holder shall make payment of the deficiency within three (3) trading days following notice thereof. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has
purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall
surrender this Warrant to the Company for cancellation within three (3) trading days of the date that the final Notice of Exercise
is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant
Shares available hereunder shall automatically reduce the outstanding number of Warrant Shares purchasable hereunder in an amount
equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number
of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form
within two (2) Business Days of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge
and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder,
the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face
hereof.

 

b)           Exercise
Price. The exercise price per share of Common Stock under this Warrant shall be the lesser of (A) $4.50 or (B) the highest
price per share of Common Stock sold in the Company’s initial public offering, multiplied by 60% (the “Exercise
Price”).

 

c)           Cashless
Exercise. In connection with a cashless exercise of the Warrant, this Warrant shall represent the right to subscribe for and
acquire the number of Warrant Shares equal to (i) the number of Warrant Shares specified by the Holder in its Notice of Exercise
(the “Total Number”) less (ii) the number of Warrant Shares equal to the quotient obtained by dividing (A) the
product of the Total Number and the applicable existing Exercise Price by (B) the Fair Market Value. “Fair Market Value”
shall mean: (1) if the Warrant Shares are listed on the NYSE American, the Nasdaq Capital Market, the Nasdaq Global Market, the
Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board or the Pink OTC Markets (or any successors to
any of the foregoing), the last reported sale price of the Warrant Shares on such exchange or Nasdaq on the date for which the
determination is being made; or (2) if the Warrant Shares are not so listed, “Fair Market Value” shall be determined
in good faith by the board of directors of the Company.

 

    	 	2	 

     

    

  

d)           Mechanics
of Exercise.

 

i.            Delivery
of Certificates Upon Exercise. If Holder exercises this Warrant, certificates for Common Stock purchased hereunder shall be
transmitted by the Company’s transfer agent to the Holder by crediting the account of the Holder’s prime broker with
The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is
then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder and such Warrant Shares have been sold or (B) the Common Stock is eligible
for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 promulgated under the Securities Act
(“Rule 144”), and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise
by the date that is five (5) trading days after the latest of (A) the delivery to the Company of the Notice of Exercise, (B) surrender
of this Warrant (if required), and (C) payment of the aggregate Exercise Price as set forth above (including by cashless exercise,
if permitted) (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been
issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such
shares for all purposes, as of the date the Warrant has been exercised in accordance with the requirements of the preceding sentence
and with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid
by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such Common Stock, having been paid.

 

ii.         Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant
Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called
for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

 

iii.         Rescission
Rights. If the Company fails to cause the Company’s transfer agent to transmit to the Holder a certificate or the certificates
representing the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right
to rescind such exercise.

 

    	 	3	 

     

    

  

iv.         Compensation
for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to cause the Company’s transfer agent to transmit to the Holder a certificate or the certificates representing
the Warrant Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required
by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases,
Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon
such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which
(x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds
(y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder
in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was
executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares
for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number
of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder
subject to payment of the Exercise Price therefor. 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 exercise of Common Stock with an aggregate sale price giving rise to
such purchase obligation 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 Common
Stock upon exercise of the Warrant as required pursuant to the terms hereof.

 

v.           No
Fractional Common Stock. No fractional Common Stock shall be issued upon the exercise of this Warrant. As to any fraction of
a Common Stock which the Holder would otherwise be entitled to purchase upon such exercise, 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 Exercise Price
or round to the nearest whole Common Stock.

 

    	 	4	 

     

    

  

e)           Beneficial
Ownership Limitation on Exercises. Notwithstanding anything to the contrary contained herein, the Company shall not effect
the exercise of any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant
to the terms and conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent
that after giving effect to such exercise, the Holder together with the other Attribution Parties (as defined below) collectively
would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the number of shares of Common Stock
outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares
of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares of Common
Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon exercise of
this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of
Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned
by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion
of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or
warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous
to the limitation contained in this Section 2(e). For purposes of this Section 2(e), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes
of this Warrant, in determining the number of outstanding Common Stock the Holder may acquire upon the exercise of this Warrant
without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding Common Stock as reflected in (x) the
Company’s most recent Annual Report on Form 10-K, Current Report on Form 8-K or other public filing made by the Company with
the Securities and Exchange Commission (the “SEC”), as the case may be, (y) a more recent public announcement
by the Company or (z) any other written notice by the Company or the Company’s transfer agent setting forth the number of
Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company receives a Notice of Exercise
from the Holder at a time when the actual number of shares of outstanding Common Stock is less than the Reported Outstanding Share
Number, the Company shall (i) notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the
extent that such Notice of Exercise would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this
Section 2(e), to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of Warrant Shares to be
purchased pursuant to such Notice of Exercise (the number of shares by which such purchase is reduced, the “Reduction
Shares”) and (ii) as soon as reasonably practicable, the Company shall return to the Holder any exercise price paid by
the Holder for the Reduction Shares. For any reason at any time, upon the written or oral request of the Holder, the Company shall
within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock
then outstanding. In any case, the number of outstanding Common Stock shall be determined after giving effect to the conversion
or exercise of securities of the Company, including this Warrant, by the Holder and any other Attribution Party since the date
as of which the Reported Outstanding Share Number was reported. In the event that the issuance of Common Stock to the Holder upon
exercise of this Warrant results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate,
more than the Maximum Percentage of the number of outstanding Common Stock (as determined under Section 13(d) of the 1934 Act),
the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership
exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab
initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after
the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid
by the Holder for the Excess Shares. Upon delivery of a written notice to the Company, the Holder, in its sole discretion may from
time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99%; provided, however, that
(i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice
is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties
and not to any other holder of the Warrants that is not an Attribution Party of the Holder. For purposes of clarity, the Common
Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially
owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. The provisions
of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section
2(e) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent
with the intended beneficial ownership limitation contained in this Section 2(e) or to make changes or supplements necessary or
desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply
to a successor holder of this Warrant. For purposes of this Section 2(e), “Attribution Parties” means, collectively,
the following Persons: (i) any investment vehicle, including, any funds, feeder funds or managed accounts, currently, or from time
to time after the Original Issue Date of this Warrant, directly or indirectly managed or advised by the Holder’s investment
manager or any of its Affiliates or principals, (ii) any direct or indirect Affiliates of the Holder or any of the foregoing, (iii)
any Person acting or who could be deemed to be acting as a “group” (as such term is used in Section 13(d) of the 1934
Act and as defined in Rule 13d-5 thereunder) together with the Holder or any of the foregoing and (iv) any other Persons whose
beneficial ownership of the Common Stock would or could be aggregated with the Holder’s and the other Attribution Parties
for purposes of Section 13(d) of the 1934 Act. For clarity, the purpose of the foregoing is to subject collectively the Holder
and all other Attribution Parties to the Maximum Percentage.

		Section 3.	Certain Adjustments.

 

a)           Stock
Splits and Dividends. If the Company at any time on or after the Original Issue Date subdivides (by any stock split, stock
dividend, recapitalization or otherwise) one or more classes of its outstanding Common Stock into a greater number of shares, the
Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares
will be proportionately increased. If the Company at any time on or after the Original Issue Date combines (by combination, reverse
stock split or otherwise) one or more classes of its outstanding Common Stock into a smaller number of shares, the Exercise Price
in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately
decreased. Any adjustment under this Section 3(a) shall become effective at the close of business on the date the subdivision or
combination becomes effective.

 

b)           Intentionally
Omitted.

 

c)           Other
Events. If any event occurs of the type contemplated by the provisions of this Section 3, but not expressly provided for by
such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights
with equity features), then the Company’s board of directors will make an appropriate adjustment in the Exercise Price and
the number of Warrant Shares so as to protect the rights of the Holder.

 

d)           Certificate
of Adjustment. Whenever the Exercise Price or number of Warrant Shares is adjusted as herein provided, the Company shall promptly
deliver to the Holder a certificate of the Company’s chief financial officer or other authorized officer setting forth the
Exercise Price and number of Warrant Shares following such adjustment and setting forth a brief statement of the facts resulting
in such adjustment.

 

    	 	6	 

     

    

  

e)           Notice to Holder.
If (i) the Company shall declare a dividend on the Common Stock, (ii) the Company shall declare a special nonrecurring cash dividend
on or a redemption of the Common Stock, (iii) the Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any Common Stock of any class or of any rights, (iv) 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 are converted into other securities, cash or property, or (v) 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 mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least
ten (10) 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, 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, redemption, rights or warrants
are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or Common Stock 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 Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation,
merger, sale, transfer or Common Stock exchange; provided that the failure to mail such notice or any defect therein or in the
mailing 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 publicly disclose such notice. 

 

f)            Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share of Common Stock, as the
case may be. For purposes of this Section 3, 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 issued and outstanding.

 

g)           Voluntary
Adjustment by Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the board of directors of the Company.

 

		Section 4.	Transfer of Warrant.

 

a)           Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and
all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer, but only after such transferee agrees to be bound by the provisions of
this Agreement. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants
in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant
shall promptly be cancelled. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the
purchase of Warrant Shares without having a new Warrant issued.

 

    	 	7	 

     

    

  

b)           New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the
Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by
the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Original
Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

c)           Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and
for all other purposes, absent actual notice to the contrary.

 

d)           Transfer
Restrictions. The Warrant may only be disposed of in compliance with state and federal securities laws and shall not transferred
unless the Warrant is (i) registered pursuant to an effective registration statement under the Securities Act and under applicable
state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information
requirements pursuant to Rule 144.

 

e)           Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any
exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for
distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities
law, except pursuant to sales registered or exempted under the Securities Act.

 

		Section 5.	Miscellaneous.

 

a)           No
Rights as a Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a
stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section
3.

 

b)           Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of
the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation,
in lieu of such Warrant or stock certificate.

 

    	 	8	 

     

    

  

c)           Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or
granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding
Business Day.

 

d)           Authorized
Common Stock.

 

        The Company will take
all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation
of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The
Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant
will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith,
be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company
in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

 

        Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (i) take all such action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (ii) use commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof,
as may be, necessary to enable the Company to perform its obligations under this Warrant.

 

         Before taking any action
which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price,
the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body having jurisdiction thereof.

 

e)           Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of the Series G Documents 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
conflicts of law thereof.

 

f)            Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered and the Holder does
not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

 

    	 	9	 

     

    

  

g)           Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder or Company
shall operate as a waiver of such right or otherwise prejudice the Holder’s or Company’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination Date. If either the Company or the Holder willfully
and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the other, such party
shall pay to the other party such amounts as shall be sufficient to cover any costs and expenses including, but not limited to,
reasonable attorneys’ fees, including those of appellate proceedings, incurred by the affected party in collecting any amounts
due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

h)           Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of: (i) the date of transmission, if such notice or communication is delivered
via email or facsimile at the email address or facsimile number set forth on the signature pages attached to the Subscription Agreement
at or prior to 5:30 p.m. (New York City time) on a trading days, (ii) the next trading days after the date of email or facsimile
transmission, if such notice or communication is delivered via email or facsimile at the email address or facsimile number set
forth on the signature pages attached to the Subscription Agreement on a day that is not a trading days or later than 5:30 p.m.
(New York City time) on any trading days, (iii) the second (2nd) trading days following the date of mailing, if sent
by U.S. nationally recognized overnight courier service or (iv) upon actual receipt by the party to whom such notice is required
to be given. The address for such notices and communications shall be as set forth on the signature page attached to the Subscription
Agreement.

 

i)            Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

 

j)            Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.

 

k)           Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and
shall be enforceable by the Holder or holder of Warrant Shares.

 

l)            Amendment.
This Warrant may be modified or amended or the provisions hereof waived in accordance with the Series G Documents.

 

m)          Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.

 

n)           Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.
