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, electronic mail 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 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 C, 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 second (2nd) 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 Company shall (i)
provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities
Transfer Program (“FAST Program”), upon the request of the Holder, credit such aggregate number of shares of Common
Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC
through its Deposit/Withdrawal at Custodian system, or (ii) if the Transfer Agent is not participating in the DTC FAST 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, which shares of Common Stock shall be freely tradeable pursuant to all applicable securities laws.
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
two (2) 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. Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly
made pursuant to a Cashless Exercise, the Company’s failure to deliver Warrant Shares to the Holder on or prior to the later of
(A) two (2) Trading Days after receipt of the applicable 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)
and (B) one (1) Trading Day after the Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless Exercise)
(such later date, the “Share Delivery Date”) shall not be deemed to be a breach of this Warrant. From the Issuance
Date through and including the Expiration Date, the Company shall maintain a transfer agent that participates in the DTC FAST Program.
Notwithstanding any other provision in this Agreement, the Holder may elect, at its sole discretion, to receive unregistered Warrant
Shares issued in response to an Exercise Notice instead of Warrant Shares (i) registered pursuant to the Registration Statement or any
other registration statement or (ii) issued pursuant to Section 1(c).


 


(b)
Exercise Price. For purposes of this Warrant, “Exercise Price” means $6.302 subject to adjustment
as provided herein.


 





 



2 120% of public
offering price.

(c)
Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, on or prior
to the Share Delivery Date, either (I) if the Transfer Agent is not participating in the DTC FAST Program, to issue and deliver to the
Holder (or its designee) a certificate for the number of Warrant Shares to which the Holder is entitled and register such Warrant Shares
on the Company’s share register or, if the Transfer Agent is participating in the DTC FAST Program, to credit the balance account
of the Holder or the Holder’s designee with DTC for such number of Warrant Shares to which the Holder is entitled upon the Holder’s
exercise of this Warrant (as the case may be) or (II) if the Registration Statement (or prospectus contained therein) covering the issuance
of the Warrant Shares that are the subject of the Exercise Notice (the “Unavailable Warrant Shares”) is not available
for the issuance of such Unavailable Warrant Shares and the Company fails to promptly (x) so notify the Holder and (y) deliver the Warrant
Shares electronically without any restrictive legend by crediting such aggregate number of Warrant Shares to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian
system (the event described in the immediately foregoing clause (II) is hereinafter referred as a “Notice Failure”
and together with the event described in clause (I) above, a “Delivery Failure”), the Company shall pay to the Holder,
in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of
the Common Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth
(5th) Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date
until such Warrant Shares are delivered or Holder rescinds such exercise, and if on or after such Share Delivery Date 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 is entitled to receive from the Company (a
“Buy-In”), then, in addition to all other remedies available to the Holder, the Company shall, within two (2) Business
Days after the Holder’s request and in the Holder’s discretion, either (i) as an indemnity for loss hereunder, 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, as an indemnity for loss hereunder, pay cash to the Holder in an amount equal to the excess (if any) of 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”)
over the product of (A) such number of Warrant Shares multiplied by (B) the lowest Closing Sale Price of the shares of 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. While
this Warrant is outstanding, the Company shall cause its transfer agent to participate in the DTC FAST Program. In addition to the foregoing
rights, (i) if the Company fails to deliver the applicable number of Warrant Shares upon an exercise pursuant to Section 1 by the applicable
Share Delivery Date, then the Holder shall have the right to rescind such exercise in whole or in part and retain and/or have the Company
return, as the case may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the
rescission of an exercise shall not affect the Company’s obligation to make any payments that have accrued prior to the date of
such notice pursuant to this Section 1(c) or otherwise except with respect to any returned portion of an exercise under this subclause
(i), and (ii) if a registration statement (which may be the Registration Statement) covering the issuance or resale of the Warrant Shares
that are subject to an Exercise Notice is not available for the issuance or resale, as applicable, of such Exercise Notice Warrant Shares
and the Holder has submitted an Exercise Notice prior to receiving notice of the non-availability of such registration statement and
the Company has not already delivered the Warrant Shares underlying such Exercise Notice electronically without any restrictive legend
by crediting such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s
or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, the Holder shall have the option,
by delivery of notice to the Company, to (x) rescind such Exercise Notice in whole or in part and retain or have returned, as the case
may be, any portion of this Warrant that has not been exercised pursuant to such Exercise Notice; provided that the rescission of an
Exercise Notice shall not affect the Company’s obligation to make any payments that have accrued prior to the date of such notice
pursuant to this Section 1(c) or otherwise, and/or (y) switch some or all of such Exercise Notice from a cash exercise to a Cashless
Exercise.


 


(d)
Cashless Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if at the time of
exercise hereof the Registration Statement is not effective (or the prospectus contained therein is not available for use) for the issuance
of all of the Warrant Shares, then 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-B)
    x (X)]	 
	 	 	A	 


 




    	3



     


    

 


For
purposes of the foregoing formula:


 


	A=	As
                                            applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable
                                            Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant
                                            to Section 1 hereof on a day that is not a Trading Day or (2) both executed and delivered
                                            pursuant to Section 1 hereof on a Trading Day prior to the opening of “regular trading
                                            hours” (as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal
                                            securities laws) on such Trading Day, (ii) at the option of the Holder, either (y) the VWAP
                                            on the Trading Day immediately preceding the date of the applicable Notice of Exercise or
                                            (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg
                                            L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise
                                            if such Notice of Exercise is executed during “regular trading hours” on a Trading
                                            Day and is delivered within two (2) hours thereafter (including until two (2) hours after
                                            the close of “regular trading hours” on a Trading Day) pursuant to Section1 hereof,
                                            or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice
                                            of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant
                                            to Section 1 hereof after the close of “regular trading hours” on such Trading
                                            Day.

     

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

     

	X=	The
    number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such
    exercise were by means of a cash exercise rather than a cashless exercise.


 


If
the Warrant Shares are issued in a Cashless Exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the
1933 Act, the Warrant Shares take on the registered characteristics of the Warrants being exercised. For purposes of Rule 144(d) promulgated
under the 1933 Act, as in effect on the Initial Exercise 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 Underwriting Agreement. Notwithstanding anything herein to the contrary, on the
Expiration Date, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section 1(d).


 


(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.


 


(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 4.99% (the “Maximum Percentage”) of the 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 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 shares or warrants, including other Registered 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 1(f). For purposes of this Section 1(f), 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), 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 (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 Registered Warrants that is
not an Attribution Party of the Holder. 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) 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) 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. So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance
under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of Common Stock as shall
be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the Registered Warrants then outstanding
(without regard to any limitations on exercise) (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 other than proportionally in connection with any
exercise of Registered Warrants or such other event covered by Section 2(a) below. The Required Reserve Amount (including, without limitation,
each increase in the number of shares so reserved) shall be allocated pro rata among the holders of the Registered Warrants based on
number of shares of Common Stock issuable upon exercise of Registered Warrants held by each holder on the Issuance Date (without regard
to any limitations on exercise) or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”).
In the event that a holder shall sell or otherwise transfer any of such holder’s Registered Warrants, each transferee shall be
allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to
any Person which ceases to hold any Registered Warrants shall be allocated to the remaining holders of Registered Warrants, pro rata
based on the number of shares of Common Stock issuable upon exercise of the Registered Warrants then held by such holders (without regard
to any limitations on exercise).


 




    	5



     


    

 


(ii)
Insufficient Authorized Shares. If, notwithstanding Section 1(g)(i) above, and not in limitation thereof, at any time while any
of the Registered Warrants remain 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 all the Registered Warrants then outstanding. 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 sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its shareholders for
the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide
each shareholder with a proxy statement and shall use its best efforts to solicit its shareholders’ approval of such increase in
authorized shares of Common Stock and to cause its board of directors to recommend to the shareholders 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 Common Shares, 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 Authorization
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 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(f); 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.


 


(h)
Warrant Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued
subject to the Warrant Agency Agreement, dated [          ], 2021 by and between the Company and Equiniti ___ (the “Warrant Agency Agreement”).
To the extent any provision of this Warrant conflicts with the express provisions of the Warrant Agency Agreement, the provisions of
this Warrant shall govern and be controlling.


 


2.
ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. 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)
Share Dividends and Splits. Without limiting any provision of Section 4, if the Company, at any time on or after the Subscription
Date, (i) pays a share dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution
on any class of capital shares that is payable in shares of Common Stock, (ii) subdivides (by any share split, share 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 share 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 shareholders 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.


 


(b)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to this Section 2, the number of Warrant
Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment
the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise
Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).


 




    	6



     


    

 


(c)
Other Events. In the event that the Company (or any Subsidiary (as defined in the Underwriting Agreement)) shall take any action
to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from dilution
or if any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by such provisions
(including, without limitation, the granting of share appreciation rights, phantom share rights or other rights with equity features),
then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment in the Exercise Price
and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that no such adjustment pursuant
to this Section 2(c) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this
Section 2, provided further that if the Holder does not accept such adjustments as appropriately protecting its interests hereunder against
such dilution, then the Company’s board of directors and the Holder shall agree, in good faith, upon an independent investment
bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding absent manifest
error and whose fees and expenses shall be borne by the Company.


 


(d)
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 shares of Common Stock.


 


3.
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments 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 Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, shares
or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend, spin off, reclassification,
corporate rearrangement, plan 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 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 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 the extent of the Maximum Percentage (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result
of such Distribution (and beneficial ownership) to the extent of any such excess) 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 pursuant to Section 2 above, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase shares, 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 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 the extent of the Maximum Percentage
(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 the extent of any such excess) 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. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or
more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company or any Subsidiary,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender
or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding
shares of Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization
or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the shares of Common Stock are effectively
converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related
transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or
other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase
agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of
this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 1(f)
on the exercise of this Warrant), the number of shares of common stock of the successor or acquiring corporation or of the Company, if
it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a
result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately
prior to such Fundamental Transaction (without regard to any limitation in Section 1(f) on the exercise of this Warrant). For purposes
of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and
the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value
of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash
or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration
it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the
event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable
at any time concurrently with, or within thirty (30) days after, the consummation of the Fundamental Transaction (or, if later, the date
of the public announcement of the applicable Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder
an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date
of the consummation of such Fundamental Transaction; provided, however, that, if the Fundamental Transaction is not within
the Company’s control, including not approved by the Company’s Board of Directors, Holder shall only be entitled to receive
from the Company or any Successor Entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value
of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of the Company in connection
with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the
holders of Common Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental
Transaction; provided, further, that if holders of Common Stock of the Company are not offered or paid any consideration
in such Fundamental Transaction, such holders of Common Stock will be deemed to have received common stock of the Successor Entity (which
Entity may be the Company following such Fundamental Transaction) in such Fundamental Transaction. “Black Scholes Value”
means the value of this Warrant based on the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg,
L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes
and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date
of the public announcement of the applicable Fundamental Transaction and the Expiration Date, (B) an expected volatility equal to the
greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365 day annualization
factor) as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying
price per share used in such calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus
the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (ii) the highest VWAP during the period
beginning on the Trading Day immediately preceding the announcement of the applicable Fundamental Transaction (or the consummation of
the applicable Fundamental Transaction, if earlier) and ending on the Trading Day of the Holder’s request pursuant to this Section
4(b) and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction
and the Expiration Date and (E) a zero cost of borrow. The payment of the Black Scholes Value will be made by wire transfer of immediately
available funds within five Business Days of the Holder’s election (or, if later, on the effective date of the Fundamental Transaction).
The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other transaction documents in accordance
with the provisions of this Section 4(b) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and
approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver
to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar
in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity
(or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon 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 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 which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions
of this 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.

(c)
[RESERVED.]


 


(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 capital shares registered under the 1934 Act and thereafter receivable upon exercise of this Warrant (or any
such other warrant)).


 


5.
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation
or other organizational documents or through any reorganization, transfer of assets, consolidation, merger, amalgamation, plan 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, which shares of Common Stock shall be freely tradeable pursuant
to all applicable securities laws. 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 SHAREHOLDER. 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 shareholder of the Company or any right to vote, give or withhold consent to any corporate action
(whether any reorganization, issue of shares, reclassification of shares, 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 shareholder
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 shareholders of the Company generally,
contemporaneously with the giving thereof to the shareholders.

10.

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 its principal executive office 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

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

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 Bid Price, 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 or electronic mail (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
Bid Price, 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.


 


(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).


 




    	12



     


    

 


(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.


 


(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) the terms of this Warrant 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 and in resolving such dispute such investment bank shall apply
such findings, determinations and the like to the terms of this Warrant, (iii) 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 (iv) 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, 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 specific performance and/or temporary, preliminary and permanent injunctive or other
equitable relief from any court of competent jurisdiction in any such case without the necessity of proving actual damages and without
posting a bond or other security. 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.


 


15.
PAYMENT OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this Warrant is placed
in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the holder otherwise
takes action to collect amounts due under this Warrant or to enforce the provisions of this Warrant or (b) there occurs any bankruptcy,
reorganization, receivership of the company 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, receivership or other proceeding, including, without limitation, attorneys’ fees and disbursements.
