ICAGEN, INC.         


 


Warrant To Purchase Common Stock


 


Warrant No.: ICGI-GPB-1


 


Issuance Date: May 15, 2017 (“Issuance
Date”)


 


Icagen, Inc., a Delaware
corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, GPB Debt Holdings II, LLC, the registered holder hereof or its permitted assigns (the “Holder”),
is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then
in effect, upon exercise of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange,
transfer or replacement hereof, the “Warrant”), at any time or times on or after the Issuance Date, but not
after 11:59 p.m., New York time, on the Expiration Date (as defined below), 857,143 (subject to adjustment as provided
herein) fully paid and non-assessable shares of Common Stock (as defined below) (the “Warrant Shares”, and such
number of Warrant Shares, the “Warrant Number”). Except as otherwise defined herein, capitalized terms in this
Warrant shall have the meanings set forth in Section 17. This Warrant was issued pursuant to Section 1 of that certain
Securities Purchase Agreement, dated as of May 15, 2017 (the “Subscription Date”), by and among the Company,
Icagen-T, Inc., a Delaware corporation, and the Holder, as amended from time to time (the “Securities Purchase Agreement”).


 




     


     


    

 


1.   EXERCISE
OF WARRANT.


 


(a)          Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section
1(f)), this Warrant may be exercised by the Holder on any day on or after the Issuance Date (an “Exercise Date”),
in whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading
Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount equal to the
Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so
exercised (the “Aggregate Exercise Price”) in cash, check or via wire transfer of immediately available funds
if the Holder did not notify the Company in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as
defined in Section 1(d)). The Holder shall not be required to deliver the original of this Warrant in order to effect an
exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have
the same effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase
the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares
shall have the same effect as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with
the terms hereof. On or before the first (1st) Trading Day following the date on which the Company has received an Exercise Notice,
the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of such Exercise Notice,
in the form attached hereto as Exhibit B, to the Holder and the Company’s transfer agent (the “Transfer
Agent”), which confirmation shall constitute an instruction to the Transfer Agent to process such Exercise Notice in
accordance with the terms herein. On or before the third (3rd) Trading Day following the date on which the Company has
received such Exercise Notice (or such earlier date as required pursuant to the 1934 Act or other applicable law, rule or regulation
for the settlement of a trade of such Warrant Shares initiated on the applicable Exercise Date), (the “Share Delivery
Date”), the Company shall; provided that the Aggregate Exercise Price has been delivered in the time period set forth
above, unless the Aggregate Exercise Price is paid through a cashless exercise (X) provided that the Transfer Agent is participating
in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number
of shares of Common Stock to which the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal
at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, upon
the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Exercise Notice,
a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder
shall be entitled pursuant to such exercise. Upon delivery of an Exercise Notice, the Holder shall be deemed for all corporate
purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective
of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing
such Warrant Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section
1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant
Shares being acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then, at the request of
the Holder, the Company shall as soon as practicable and in no event later than three (3) Business Days after any exercise and
at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing
the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the
number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued
upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest
whole number. The Company shall pay any and all transfer, stamp, issuance and similar taxes, costs and expenses (including, without
limitation, fees and expenses of the Transfer Agent) that may be payable with respect to the issuance and delivery of Warrant Shares
upon exercise of this Warrant.

(b)          Exercise
Price. For purposes of this Warrant, “Exercise Price” means $3.50, subject to adjustment as provided herein.


 


(c)          Company’s
Failure to Timely Deliver Securities. If the Company fails on or prior to the Share Delivery Deadline to issue and deliver
to the Holder (or its designee) a certificate and register such shares of Common Stock on the Company’s share register or,
credit the balance account of the Holder or the Holder’s designee with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s exercise hereunder (as the case may be pursuant to this Section 1(c) and/or
pursuant to the Company’s obligation pursuant to clause (ii) below) and if on or after such Share Delivery Deadline the Holder
purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder
of all or any portion of the number of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving
from the Company (a “Buy-In”), then, in addition to all other remedies available to the Holder, the Company
shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash
to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket
expenses, if any) for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or
on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and
deliver such certificate (and to issue such shares of Common Stock) or credit the balance account of such Holder or such Holder’s
designee, as applicable, with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise
hereunder (as the case may be) (and to issue such Warrant Shares) shall terminate, or (ii) promptly honor its obligation to so
issue and deliver to the Holder a certificate or certificates representing such Warrant Shares or credit the balance account of
such Holder or such Holder’s designee, as applicable, with DTC for the number of Warrant Shares to which the Holder is entitled
upon the Holder’s exercise hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if
any) of the Buy-In Price over the product of (A) such number of Warrant Shares multiplied by (B) the lowest Closing Sale Price
or Closing Bid Price (as the case may be) of the Common Stock on any Trading Day during the period commencing on the date of the
applicable Exercise Notice and ending on the date of such issuance and payment under this clause (ii) (the “Buy-In Payment
Amount”). Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law
or in equity, including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s
failure to timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common
Stock) upon the exercise of this Warrant as required pursuant to the terms hereof.

(d)          Cashless
Exercise. If the Company is a Trading Issuer and at the applicable time an effective registration statement is not available
for the issuance of Warrant Shares and notwithstanding anything contained herein to the contrary (other than Section 1(f)
below), the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment
otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to
receive upon such exercise the “Net Number” of Warrant Shares determined according to the following formula
(a “Cashless Exercise”):


 


Net Number = (A x B) - (A x C)


D


For purposes of the
foregoing formula:


 


A= the total number of shares with
respect to which this Warrant is then being exercised.


 


B = the lowest Closing Bid Price
or Closing Sale Price (as the case may be) during the ten (10) consecutive Trading Days ending at the close of business on the
Principal Market immediately prior to the time of exercise as set forth in the applicable Exercise Notice.


 


C = the Exercise Price then in
effect for the applicable Warrant Shares at the time of such exercise.


 


D = as applicable: the Closing
Sale Price or Closing Bid Price (as the case may be) of the Common Stock on the Trading Day immediately preceding the date of the
applicable Exercise Notice.


 


For purposes of Rule
144(d) promulgated under the 1933 Act, as in effect on the Subscription Date, it is intended that the Warrant Shares issued in
a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be
deemed to have commenced, on the date this Warrant was originally issued pursuant to the Securities Purchase Agreement.


 


(e)          Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares
to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares that are
not disputed and resolve such dispute in accordance with Section 13.


 




    	 	4	 



     


    

 


(f)          Limitations
on Exercises. 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 collectively would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the
shares of Common Stock outstanding immediately after giving effect to such exercise, such determination by the Company to be based
solely upon the Reported Outstanding Share Number (as defined below) and the number of shares disclosed to the Company by Holder
as being beneficially owned by the Holder and the other Attribution Parties. 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 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, including, without limitation, the Warrant) 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 1(f)(i). For purposes of this
Section 1(f)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes
of determining the number of outstanding shares of 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 shares of Common Stock as reflected in (x) the
Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public
filing with 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 Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the “Reported
Outstanding Share Number”). If the Company receives an Exercise Notice from the Holder at a time when the actual number
of outstanding shares of 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 Exercise Notice would otherwise
cause the Holder’s beneficial ownership, as determined pursuant to this Section 1(f)(i), to exceed the Maximum Percentage,
the Holder must notify the Company of a reduced number of Warrant Shares to be acquired pursuant to such Exercise Notice (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
shares of 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 shares 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 shares of 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 may from time to time increase (with such increase not effective
until the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not
in excess of 9.99% as specified in such notice; provided that 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. For purposes of clarity, the shares of 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. No prior inability to
exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph
with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 1(f)(i) 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 1(f)(i) 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.

(g)          Reservation
of Shares.


 


(i)          Required
Reserve Amount. Commencing on the Closing Date and continuing as long as this Warrant remains outstanding (the “Share
Reserve Period”), the Company shall at all times keep reserved for issuance under this Warrant at least 200% of the maximum
number of shares of Common Stock as shall from time to time be necessary to satisfy the Company’s obligation to issue shares
of Common Stock under this Warrant (without regard to any limitations on exercise and assuming for purposes of this Section
1(g) that the Holder does not exercise any portion of this Warrant on a Cashless Basis and in any event does not exercise this
Warrant until the last calendar date prior to the Expiration Date)  (the “Required Reserve Amount”); provided
that at no time shall the number of shares of Common Stock reserved pursuant to this Section 1(g)(i) be reduced.


 


(ii)         Insufficient
Authorized Shares. If, notwithstanding Section 1(g)(i) above, and not in limitation thereof, at any time while this
Warrants remains outstanding, the Company does not have a sufficient number of authorized and unreserved shares of Common Stock
to satisfy its obligation to reserve the Required Reserve Amount (an “Authorized Share Failure”), then the Company
shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for this Warrant. Without limiting the generality of the foregoing
sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety
(90) days after the occurrence of such Authorized Share Failure, the Company shall either (i) hold a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common Stock, or (ii) have cured the Authorized Share Failure
by, among other required items, obtaining a written consent of the required percentage of holders of shares Common Stock for the
required increase in authorized shares and had taken any and all other such action necessary to rectify the Authorized Share Failure
including, but not limited to, providing the non-consenting stockholders with an information statement and a Form 14(C) and filed
with the SEC such Form 14(C). In connection with such meeting as set forth in (i) above, the Company shall provide each stockholder
with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized
shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. In
the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of this Warrant due to the failure
by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares of Common Stock (such
unavailable number of shares of Common Stock, the “Authorization Failure Shares”), in lieu of delivering such
Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the cancellation of such portion of this
Warrant exercisable into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorization
Failure Shares and (y) the greatest Closing Sale Price or Closing Bid Price (as the case may be) of the Common Stock on any Trading
Day during the period commencing on the date the Holder delivers the applicable Exercise Notice with respect to such Authorization
Failure Shares to the Company and ending on the date of such issuance and payment under this Section 1(g) (or the Exercise
Price if the Company is not then a Trading Issuer); and (ii) to the extent the Holder purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorization Failure Shares, any Buy-In
Payment Amount, brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith.
Nothing contained in this Section 1(g) shall limit any obligations of the Company under any provision of the Securities
Purchase Agreement. 


 




    	 	6	 



     


    

 


2.    ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES; RESET OF EXERCISE PRICE. The Exercise Price and number of Warrant Shares issuable
upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.


 


(a)          Stock
Dividends and Splits. Without limiting any provision of Section 2(b) or Section 4, if the Company, at any time
on or after the Subscription Date, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock
or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by
any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock
into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its
then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common Stock 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 clause (i) of this paragraph shall become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph
shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment
under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise
Price shall be adjusted appropriately to reflect such event.


 




    	 	7	 



     


    

 


(b)          Adjustment
Upon Issuance of Shares of Common Stock Prior to the Closing Date of a Qualifying PO. In addition to and not in limitation
of any other rights of the Holder under this Warrant including, but not limited to, Section 2 hereof and/or any other Transaction
Document, if, at any time while this Note is outstanding and whenever on or after the Subscription Date but prior to the closing
date of a Qualifying PO (as defined below), the Company, the Parent and/or any Subsidiary (as defined in the Securities Purchase
Agreement), in any manner sells or grants any option to purchase, issues or sells or grants any right to reprice, and/or otherwise
sells, disposes of and/or issues any shares of Common Stock or Common Stock Equivalents (as defined below) (including upon conversion,
exercise or otherwise) entitling any Person to acquire shares of Common Stock at a price per share of Common Stock that is lower
than the then Exercise Price (such lower price, the “New Issuance Price” and each such issuance, a “Dilutive
Issuance” and collectively, “Dilutive Issuances”), (if the holder of shares of Common Stock or Common
Stock Equivalents so issued and/or any holder of Common Stock and/or Common Stock Equivalents as of the Subscription Date or issued
subsequent thereto, shall at any time, whether by amendment, supplement, operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise be entitled under the terms of any such instruments to receive shares
of Common Stock at a price per share that is lower than the Exercise Price, such issuance shall be deemed to have occurred for
less than the Exercise Price on such date of the Dilutive Issuance), then the then Exercise Price shall be reduced to equal the
New Issuance Price.  For purposes of clarification, if the Company, the Parent and/or any Subsidiary issues, sells and/or
otherwise disposes of any shares of Common Stock at a price less than the then Exercise Price, the then Exercise Price shall immediately
be reduced to the New Issuance Price on the date of such Dilutive Issuance. All adjustments provided for in this Section 2(b)
shall be made whenever any such Common Stock or Common Stock Equivalents are issued. Notwithstanding anything to the contrary in
the foregoing, if a Dilutive Issuance consists of the issuance and/or sale of both Common Stock and Common Stock Equivalents or
two or more Common Stock Equivalents as units (each, a “Share and/or a CSE Issuance”), in determining the value
of the component parts of the unit issued and/or sold in a Share and/or a CSE Issuance no value will be attributed to Common Stock
Equivalents and the New Issuance Price as a result thereof will be the lowest of (i) the lowest purchase price per unit, (ii) the
lowest conversion, exercise and/or exchange price to acquire one (1) share of Common Stock of any Common Stock Equivalent included
in a unit if a unit also includes shares of Common Stock, and (iii) if no shares of Common Stock are included in a unit, the lowest
exercise, conversion and/or exchange price to acquire one (1) share of Common Stock of the Common Stock Equivalents comprising
a unit, such lowest price of (i)-(iii) shall be the “Lowest Price;” provided, however, a Dilutive
Issuance and a resulting New Issuance Price relating to a Share and/or a CSE Issuance shall only occur if the Lowest Price relating
to a Share and/or a CSE Issuance is lower than the then Exercise Price. Notwithstanding the foregoing, no adjustment will be made
under this Section 2(b) in respect of an Exempt Issuance.   The Company shall notify the Holder in writing, no later
than the first Trading Day following the issuance of any Common Stock or Common Stock Equivalents subject to this Section 2(b),
indicating therein the applicable Lowest Price, issuance price, reset price, exchange price, conversion price and Exercise Price
and other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether
or not the Parent provides a Dilutive Issuance Notice upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive
a number of shares of Common Stock based upon the New Issuance Price on or after the date of such Dilutive Issuance, regardless
of whether the Holder accurately refers to the New Issuance Price in any Exercise Notice. For purposes hereof, the term “Common
Stock Equivalents” means any securities (as defined under the 1933 Act) including, but not limited to, any Options and/or
Convertible Securities of the Company, the Parent and/or any Subsidiaries which would entitle the Holder thereof to acquire at
any time shares of Common Stock, including, without limitation, any debt, preferred stock, right, option, warrant or other instrument
that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the Holder thereof to receive, shares
of Parent Common Stock. If the Parent, the Company and/or any Subsidiary enters into a Variable Rate
Transaction (as defined in the Securities Purchase Agreement) despite the prohibition set forth in the Securities Purchase Agreement,
the Parent shall be deemed to have issued shares of Common Stock or Common Stock Equivalents at the lowest possible price at which
such securities may be converted, exchanged and/or exercised under the terms of such Variable Rate Transaction.


 




    	 	8	 



     


    

 


(c)          Calculations.
All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100th of a share, as
applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be considered an issuance or sale of Common Stock.


 


(d)          Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant, with the prior written consent of the Holders,
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.


 


(e)          Certain
Reset Right Upon a Qualifying PO. If on or after the Subscription Date, the Company consummates a Qualifying PO, and on
the closing date of such Qualifying PO, the then Exercise Price in effect on such date is greater than the Qualifying PO Per Share
Sale Price (as defined below), then the Exercise Price shall automatically and without any action by the Company or otherwise,
be reset to the Qualifying PO Per Share Sale Price.  A “Qualifying PO Per Share Sale Price” shall
be as applicable (i) the gross purchase price a share of Common Stock is sold to the public in the Qualifying PO if only shares
of Common Stock are sold to the public in such Qualifying PO, (ii) the gross purchase price a unit consisting of shares of Common
Stock and Common Stock Equivalents is sold to the public in the Qualifying PO, or (iii) the sum equal to the gross purchase price
of (a) one (1) share of Common Stock, and (b) a Common Stock Equivalent if such are sold to each purchaser in a Qualifying PO but
not in a unit.


 


3.    RIGHTS
UPON DISTRIBUTION OF ASSETS. In addition to any adjustments provided for elsewhere in this Warrant including, but not limited
to, pursuant to Section 2 above, if the Company shall declare or make any dividend or other distribution of its assets (or
rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without
limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets
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 Warrant, then, in each such case, the Holder shall
to be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations
or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date
on 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, that to the extent that the
Holder’s right to participate in any such Distribution would result in the Holder and the other Attribution Parties exceeding
the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (and shall not
be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership)
to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time or
times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage,
at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution
or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).

4.          PURCHASE
RIGHTS; FUNDAMENTAL TRANSACTIONS.


 


(a)          Purchase
Rights. In addition to any adjustments provided for elsewhere in this Warrant including, but not limited to, pursuant to Section
2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock,
warrants, securities or other property pro rata to the record holders of any class 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 exercise
of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the
Maximum Percentage) 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, issuance or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate
in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then
the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial
ownership of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and such
Purchase Right to such extent shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its
right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time
or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right
or on any subsequent Purchase Right held similarly in abeyance) to the same extent as if there had been no such limitation).

(b)          Fundamental
Transactions. Subject to the rights of (i) the Company or a Successor Entity (as the case may be) to redeem this Warrant pursuant
to Section 4(c)(i), and (ii) the Holder to require the redemption of this Warrant by the Company or the Successor Entity
(as the case may be) pursuant to Section 4(c)(ii), the Company shall not enter into or be party to a Fundamental Transaction
unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Warrant and the other Transaction
Documents (as defined in the Securities Purchase Agreement) in accordance with the provisions of this Section 4(b) pursuant
to written agreements in form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction,
including agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for
a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise
of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and
with an exercise price which applies the exercise 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 adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic
value of this Warrant immediately prior to the consummation of such Fundamental Transaction); and (ii) the Successor Entity (including
the Parent Entity) is a publicly traded corporation whose shares of common stock are quoted or listed on an Eligible Market. Upon
the closing on the closing date of a Fundamental Transaction (an “FT Closing Date”), and subject to the rights
of (A) the Company or a Successor Entity (as the case may be) to redeem this Warrant pursuant to Section 4(c)(i), and (B)
the Company or the Successor Entity including the Parent Entity (as the case may be) to redeem this Warrant pursuant to a demand
of the Holder pursuant to Section 4(c)(ii), the Successor Entity shall succeed to, and be substituted for (so that from
and after the date of the applicable Fundamental Transaction, the provisions of this Warrant 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 Warrant and the other Transaction Documents with
the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction,
unless there is a redemption under 4(c)(i) or 4(c)(ii), the Successor Entity shall deliver to the Holder confirmation that there
shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in
lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under
Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant
prior to the applicable Fundamental Transaction, such shares of publicly traded common stock (or its equivalent) of the Successor
Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of the applicable
Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard
to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. In addition
to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to
which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares
of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder
will thereafter have the right to receive upon any full or partial (as proportionately determined) exercise of this Warrant at
any time (i) prior to the FT Closing Date, and/or (ii) at any time following a FT Closing Date if no redemption occurred on the
FT Closing Date unless there is a redemption under Section 4(c)(i) or Section 4(c)(ii) but prior to the Expiration
Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property (except such items still issuable
under Sections 3 and 4(a) above, which shall continue to be receivable thereafter) issuable upon the exercise of the Warrant
prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including
warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the
applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction
(without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be
in a form and substance reasonably satisfactory to the Holder; provided, however, notwithstanding anything to the
contrary or elsewhere, if the Company or the Successor Entity, including the Parent Entity, elects to redeem this Warrant pursuant
to Section 4(c)(i) and complies with such related provisions and if on the FT Closing Date this Warrant or any portion of
this Warrant is outstanding, the Company shall have the right to redeem this Warrant as provided in Section 4(c)(i) below.


 




    	 	11	 



     


    

 


(c)          Redemption
of Warrant in Certain Events.


 


(i)          Company/Successor
Entity Fundamental Redemption Right. Subject to the rights of the Holder pursuant to Section 4(c)(ii) and notwithstanding
anything to the contrary provided in Section 4(b) above, the Company or any Successor Entity (as the case may be) shall
have the right on a FT Closing Date to redeem this Warrant provided the Company or the Successor Entity including a Parent Entity
(as the case may be) provides to the Holder written notice of such election pursuant to Section 8 hereof, and paying to
the Holder in full, in cash on the FT Closing Date the Black Scholes Value or the Event of Default Black Scholes Value (if on the
FT Closing Date an Event of Default (as defined in the Notes) has occurred and is continuing), the “Warrant Redemption
Price”, in accordance with and pursuant to this Section 4(c)(i), and on such FT Closing Date the Company or the
Successor Entity including a Parent Entity (as the case may be) shall also provide written notice to the Holder of the payment
of the Warrant Redemption Price, the amount thereof and the calculations as to how such Warrant Redemption Price was determined
(including whether such was the Black Scholes Value or the Event of Default Black Scholes Value). Notwithstanding that the Company
or the Successor Entity (as the case may be) has delivered notice of election to redeem this Warrant pursuant to this Section
4(c)(i) the Holder may nevertheless exercise this Warrant in whole or in part at any time and from time to time through and
including the last Trading Day prior to the FT Closing Date. If the Warrant Redemption Price is not received by the Holder in full,
in cash (by wire transfer or bank check) by 11:59 p.m. (New York City time) by the first (1st) Trading Day following
the FT Closing Date, the right of the Company or the Successor Entity (as the case may be) shall terminate with respect to that
Fundamental Change as shall all future redemption rights of the Company (including to have a Successor Entity do the same) to elect
to redeem this Warrant pursuant to Section 4(c)(i) or otherwise and the Holder shall have the same rights set forth in Section
4(b) it would have had but for the election of the Company pursuant to this Section 4(c)(i). The agreement governing
the Fundamental Transaction shall make provision for redemption of the Warrant by the Company or the Successor Entity and also
for if the Company or the Successor Entity (as the case may be) elects to redeem this Warrant pursuant to Section 4(c)(i)
but fails to timely honor all of their respective obligations pursuant to Section 4(c)(i).


 




    	 	12	 



     


    

 


(ii)         Mandatory
Fundamental Transaction Redemption at the Request of the Holder. Notwithstanding the provisions of Sections 4(b) and/or
4(c)(i), at the request of the Holder delivered at any time commencing on the earliest to occur of (x) the public disclosure
of any Fundamental Transaction, (y) the consummation of any Fundamental Transaction and (z) the Holder first becoming aware of
any Fundamental Transaction through the date that is thirty (30) days after the public disclosure of the consummation of such Fundamental
Transaction by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the Company or the Successor Entity including
the Parent Entity (as the case may be) shall purchase this Warrant from the Holder on the date of such request by paying to the
Holder cash an amount equal to the Black Scholes Value (or the Event of Default Black Scholes Value if on the date of the required
redemption payment to the Holder, an Event of Default exists). Notwithstanding anything to the contrary contained herein, if the
FT Closing Date occurs prior to the foregoing thirty (30) day time period, the Company or Successor Entity (as the case may be)
may pay the Warrant Redemption Price on the FT Closing Date and thereafter, if all the redemption procedures required herein including
Section 8 are followed and the Warrant is redeemed in full, this Warrant shall terminate.


 


(iii)        Event
of Default Redemption. Notwithstanding Section 4(c)(i) and (ii) and Section 4(b) above, at the request of the
Holder delivered at any time after the occurrence of an Event of Default (as defined in the Notes and regardless of if the Notes
are no longer outstanding), the Company or the Successor Entity (as the case may be) shall purchase this Warrant from the Holder
on the date of such request by paying to the Holder cash in an amount equal to the Event of Default Black Scholes Value.


 


(d)          Application.
The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and Corporate
Events and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to
any limitations on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum
Percentage, applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon
exercise of this Warrant (or any other warrant)).


 


5.    NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined
in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any reorganization,
transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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, and will at all times in good
faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder.
Without limiting the generality of the foregoing, the Company (a) shall not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (b) shall take all such actions as may
be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common
Stock upon the exercise of this Warrant. Notwithstanding anything herein to the contrary, if after the sixty (60) calendar day
anniversary of the Issuance Date, the Holder is not permitted to exercise this Warrant in full for any reason (other than pursuant
to restrictions set forth in Section 1(f) hereof), the Company shall use its best efforts to promptly remedy such failure,
including, without limitation, obtaining such consents or approvals as necessary to permit such exercise into shares of Common
Stock.

6.    WARRANT
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in its capacity as a
holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company
for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity as
the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to
any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance
or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the
Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained
in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this
Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors
of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and other
information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.


 


7.    REISSUANCE
OF WARRANTS.


 


(a)          Transfer
of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company
will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered
as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and,
if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance

(b)          Lost,
Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below shall
suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to
the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the
Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the Warrant Shares then underlying this Warrant.


 


(c)          Exchangeable
for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the
Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase
the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such
portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for
fractional shares of Common Stock shall be given.


 




    	 	14	 



     


    

 


(d)          Issuance
of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant
(i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to
purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a)
or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying
the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this
Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date,
and (iv) shall have the same rights and conditions as this Warrant.


 


8.    NOTICES.
Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance
with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all
actions taken pursuant to this Warrant (other than the issuance of shares of Common Stock upon exercise in accordance with the
terms hereof), including in reasonable detail a description of such action and the reason therefor. Without limiting the generality
of the foregoing, the Company will give written notice to the Holder (i) immediately upon each adjustment of the Exercise Price
and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s), (ii)
at least ten (10) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend
or distribution upon the shares of Common Stock or (B) for determining rights to vote with respect to any Fundamental Transaction,
dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction
with such notice being provided to the Holder, (iii) at least ten (10) Trading Days prior to an FT Closing Date, and (iv) within
one (1) Business Day of the occurrence of an Event of Default (as defined in the Notes), setting forth in reasonable detail any
material events with respect to such Event of Default and any efforts by the Company to cure such Event of Default. To the extent
that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its
Subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement)
pursuant to a Current Report on Form 8-K. It is expressly understood and agreed that the time of execution specified by the Holder
in each Exercise Notice shall be definitive and may not be disputed or challenged by the Company.


 


9.    AMENDMENT
AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant (other than Section 1(f)) may be amended and
the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the
Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing and signed by an authorized
representative of the waiving party.


 


10.  SEVERABILITY.
If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent
jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the
broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect
the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material
change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability
of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties
or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good
faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which
comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

11.  GOVERNING
LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction,
validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without
giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably
waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof to the Company at the address set forth in Section 9(f) of the Securities Purchase Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof. The Company hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction
of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action
or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner
permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other
legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder, to realize
on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder.
THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION
OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.


 


12.  CONSTRUCTION;
HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against
any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or
affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents shall have
the meanings ascribed to such terms on the Closing Date (as defined in the Securities Purchase Agreement) in such other Transaction
Documents unless otherwise consented to in writing by the Holder.


 


13.  DISPUTE
RESOLUTION.


 


(a)          Submission
to Dispute Resolution.


  


(i)        In
the case of a dispute relating to the Exercise Price, the Closing Sale Price, the Closing Bid Price, the Lowest Price, the Black
Scholes Value, the Event of Default Black Scholes Value or fair market value or the arithmetic calculation of the number of Warrant
Shares (as the case may be) (including, without limitation, a dispute relating to the determination of any of the foregoing), the
Company or the Holder (as the case may be) shall submit the dispute to the other party via facsimile (A) if by the Company, within
two (2) Business Days after the occurrence of the circumstances giving rise to such dispute or (B) if by the Holder, at any time
after the Holder learned of the circumstances giving rise to such dispute. If the Holder and the Company are unable to promptly
resolve such dispute relating to such Exercise Price, such Closing Sale Price, such Closing Bid Price, such Lowest Price, such
Black Scholes Value, such Event of Default Black Scholes Value or such fair market value or such arithmetic calculation of the
number of Warrant Shares (as the case may be), at any time after the second (2nd) Business Day following such initial notice by
the Company or the Holder (as the case may be) of such dispute to the Company or the Holder (as the case may be), then the Holder
may, at its sole option, select an independent, reputable investment bank to resolve such dispute.


 




    	 	16	 



     


    

 


 


(ii)       The
Holder and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in
accordance with the first sentence of this Section 13 and (B) written documentation supporting its position with respect to such
dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5th) Business Day immediately following the date on
which the Holder selected such investment bank (the “Dispute Submission Deadline”) (the documents referred to
in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “Required Dispute Documentation”)
(it being understood and agreed that if either the Holder or the Company fails to so deliver all of the Required Dispute Documentation
by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute Documentation shall no longer
be entitled to (and hereby waives its right to) deliver or submit any written documentation or other support to such investment
bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation
that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless otherwise agreed to in writing by
both the Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled
to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other
than the Required Dispute Documentation).


 


(iii)      The
Company and the Holder shall cause such investment bank to determine the resolution of such dispute and notify the Company and
the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline. The fees
and expenses of such investment bank shall be borne solely by the Company, and such investment bank’s resolution of such
dispute shall be final and binding upon all parties absent manifest error.


 




    	 	17	 



     


    

 


(b)          Miscellaneous.
The Company expressly acknowledges and agrees that (i) this Section 13 constitutes an agreement to arbitrate between the Company
and the Holder (and constitutes an arbitration agreement) under the rules then in effect under § 7501, et seq. of the New
York Civil Practice Law and Rules (“CPLR”) and that the Holder is authorized to apply for an order to compel
arbitration pursuant to CPLR § 7503(a) in order to compel compliance with this Section 13, (ii) a dispute relating to the
Exercise Price includes, without limitation, disputes as to (A) whether an issuance or sale or deemed issuance or sale of Common

(C) whether any issuance or sale or deemed issuance or sale of Common Stock was an issuance or sale or deemed issuance or sale
of Excluded Securities, (D) whether an agreement, instrument, security or the like constitutes and Option or Convertible Security
and (E) whether a Dilutive Issuance occurred, (iii) the terms of this Warrant and each other applicable Transaction Document shall
serve as the basis for the selected investment bank’s resolution of the applicable dispute, such investment bank shall be
entitled (and is hereby expressly authorized) to make all findings, determinations and the like that such investment bank determines
are required to be made by such investment bank in connection with its resolution of such dispute (including, without limitation,
determining (A) whether an issuance or sale or deemed issuance or sale of Common Stock occurred under Section 2(b), (B) the consideration
per share at which an issuance or deemed issuance of Common Stock occurred, (C) whether any issuance or sale or deemed issuance
or sale of Common Stock was an issuance or sale or deemed issuance or sale of Excluded Securities, (D) whether an agreement, instrument,
security or the like constitutes and Option or Convertible Security and (E) whether a Dilutive Issuance occurred) and in resolving
such dispute such investment bank shall apply such findings, determinations and the like to the terms of this Warrant and any other
applicable Transaction Documents, (iv) the Holder (and only the Holder), in its sole discretion, shall have the right to submit
any dispute described in this Section 13 to any state or federal court sitting in The City of New York, Borough of Manhattan in
lieu of utilizing the procedures set forth in this Section 13 and (v) nothing in this Section 13 shall limit the Holder from obtaining
any injunctive relief or other equitable remedies (including, without limitation, with respect to any matters described in this
Section 13).


 


14.  REMEDIES,
CHARACTERIZATION, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative
and in addition to all other remedies available under this Warrant and 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 right of the Holder to pursue
actual and consequential damages for any failure by the Company to comply with the terms of this Warrant. 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, exercises and the like (and the computation thereof) shall be the amounts
to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company
(or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the
event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available
remedies, to an injunction restraining any 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 Warrant (including, without
limitation, compliance with Section 2 hereof). The issuance of shares and certificates for shares as contemplated hereby upon the
exercise of this Warrant shall be made without charge to the Holder or such shares for any issuance tax or other costs in respect
thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than the Holder or its agent on its behalf.

or other proceedings affecting company creditors’ rights and involving a claim under this Warrant, then the Company shall
pay the costs incurred by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization,
