Warrant
No.: B-


 


Date
of Issuance: April __, 2020 (“Issuance Date”)


 


Sigma
Labs, Inc., a Nevada corporation (the “Company”), hereby certifies that, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, [BUYER], 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 (the “Initial Exercisability Date”), but not after 11:59
p.m., New York time, on the Expiration Date (as defined below), _________________ (subject to adjustment as provided herein) fully
paid and non-assessable shares of Common Stock (as defined below) (the “Warrant Shares”, and such aggregate
number of Warrant Shares issuable hereunder as of any time of determination, the “Warrant Number”). Except
as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 17. This Warrant is
one of the Warrants to Purchase Common Stock (the “Registered Warrants”) issued pursuant to (i) Section 1 of
that certain Securities Purchase Agreement, dated as of April 2, 2020 (the “Subscription Date”), by and among
the Company and the investors (the “Buyers”) referred to therein, as amended from time to time (the “Securities
Purchase Agreement”), (ii) the Company’s Registration Statement on Form S-3 (File number 333-225377) (the “Registration
Statement”) and (iii) the Company’s prospectus supplement dated as of April ___, 2020.


 


Notwithstanding
anything herein to the contrary, the Aggregate Exercise Price (as defined below) of this Warrant, except for a nominal exercise
price of $0.0001 per Warrant Share, was pre-funded to the Company on or prior to the initial Issuance Date and, consequently,
no additional consideration (other than the nominal exercise price of $0.0001 per Warrant Share) shall be required to be paid
by the Holder to any Person to effect any exercise of this Warrant.


 




    	 



     


    

 


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 Initial Exercisability 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 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 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 (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program and such Warrant Shares are eligible to be resold pursuant to Rule 144 or an effective
registration statement, 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 (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or
such Warrant Shares are not eligible to be resold pursuant to Rule 144 or an effective registration statement, 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 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 (i) 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 (ii) 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’s Fast Automated Securities Transfer Program. For the avoidance of doubt, no ink original Exercise Notices, other
notices or medallion guarantees will be required by the Holder to exercise this Warrant or for the Holder take any other action
in connection herewith. Notwithstanding any other provision in
this Agreement, if the Holder delivers one or more Exercise Notices to the Company on or prior to the time of issuance of this
Warrant, the Company shall honor each such Exercise Notice as if such Warrant was outstanding as of the time such Exercise Notice
was delivered to the Company, except that if a Share Delivery Date as so calculated hereunder would be earlier than the Issuance
Date, such Share Delivery Date shall alternatively occur on the Issuance Date of this Warrant.

(b)
Exercise Price. For purposes of this Warrant, “Exercise Price” means $2.782, subject to adjustment as
provided herein.


 


(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 Automated Securities Transfer
Program or such Warrant Shares are not eligible to be resold pursuant to Rule 144 or an effective registration statement, 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
Automated Securities Transfer Program and such Warrant Shares are eligible to be resold pursuant to Rule 144 or an effective registration
statement, 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 a Registration
Statement 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 (solely to the extent such Unavailable
Warrant Shares were ever available pursuant to such Registration Statement) 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”), then, in addition to all other remedies available to the Holder, (X) the Company shall
pay in cash to the Holder on each day after the Share Delivery Date and during such Delivery Failure an amount equal to 2% of
the product of (A) the sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery
Date and to which the Holder is entitled, multiplied by (B) any trading price of the Common Stock selected by the Holder in writing
as in effect at any time during the period beginning on the applicable Exercise Date and ending on the applicable Share Delivery
Date, and (Y) the Holder, upon written notice to the Company, may void its Exercise Notice with respect to, 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 voiding of an Exercise Notice shall not affect the Company’s obligations to make any payments which have accrued
prior to the date of such notice pursuant to this Section 1(c) or otherwise. In addition to the foregoing, if on or prior to the
Share Delivery Date either (I) the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or
such Warrant Shares are not eligible to be resold pursuant to Rule 144 or an effective registration statement, the Company shall
fail 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, if the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program and such Warrant
Shares are eligible to be resold pursuant to Rule 144 or an effective registration statement, the Transfer Agent shall fail to
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 or pursuant to the Company’s obligation pursuant to clause
(ii) below or (II) a Notice Failure occurs, and if on or after such Share Delivery Date the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock corresponding to 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 and has not received from the Company in connection
with such Delivery Failure or Notice Failure, as applicable (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) 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 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. 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, 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 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.


 




    	3



     


    

 


(d)
Cashless Exercise. 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 quotient of (x) the sum of the VWAP of the Common Stock of each of the twenty (20) 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, divided by (y)
twenty (20).


 


C
= $0.0001 (as adjusted for stock splits, stock dividends, stock combinations, recapitalizations and similar events).


 




    	4



     


    

 


D
= as applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable
Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not
a Trading Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day prior to the opening of “regular
trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading
Day, (ii) the Bid Price of the Common Stock as of the time of the Holder’s execution of the applicable Exercise Notice if
such Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours
thereafter pursuant to Section 1(a) hereof, or (iii) the Closing Sale Price of the Common Stock on the date of the applicable
Exercise Notice if the date of such Exercise Notice is a Trading Day and such Exercise Notice is both executed and delivered pursuant
to Section 1(a) hereof after the close of “regular trading hours” on such Trading Day.


 


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 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.


 






    	5



     


    

 


(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 stock 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)(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), 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 or redemption 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 Closing 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).


 


(ii)
Insufficient Authorized Shares. If, notwithstanding Section 1(g)(i), 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. Notwithstanding the foregoing, if any such time of an Authorized
Share Failure, the Company is able to obtain the written consent of a majority of the shares of its issued and outstanding shares
of Common Stock to approve the increase in the number of authorized shares of Common Stock, the Company may satisfy this obligation
by obtaining such consent and submitting for filing with the SEC an Information Statement on Schedule 14C. 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 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. Nothing contained in this Section 1(f) shall limit any obligations of the Company under any provision of the Securities
Purchase Agreement.

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)
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
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. 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.


 






    	8



     


    

 


(b)
Adjustment Upon Issuance of Shares of Common Stock. If and whenever on or after the Subscription Date, the Company grants,
issues or sells (or enters into any agreement to grant, issue or sell), or in accordance with this Section 2 is deemed to have
granted, issued or sold, any shares of Common Stock (including the grant, issuance or sale of shares of Common Stock owned or
held by or for the account of the Company, but excluding any Excluded Securities granted, issued or sold or deemed to have been
granted, issued or sold) for a consideration per share (the “New Issuance Price”) less than a price equal to
the Exercise Price in effect immediately prior to such grant, issuance or sale or deemed grant, issuance or sale (such Exercise
Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”),
then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the New
Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Exercise Price and
the New Issuance Price under this Section 2(b)), the following shall be applicable:








 


(i)
Issuance of Options. If the Company in any manner grants, issues or sells (or enters into any agreement to grant, issue
or sell) any Options and the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise
of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option
or otherwise pursuant to the terms thereof is less than the Applicable Price, then such share of Common Stock shall be deemed
to be outstanding and to have been issued and sold by the Company at the time of the granting , issuance or sale (or the time
of execution of such agreement to grant, issue or sell, as applicable) of such Option for such price per share. For purposes of
this Section 2(b)(i), the “lowest price per share for which one share of Common Stock is at any time issuable upon the exercise
of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such
Option or otherwise pursuant to the terms thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts
of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting,
issuance or sale (or pursuant to the agreement to grant, issue or sell, as applicable) of such Option, upon exercise of such Option
and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant
to the terms thereof and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable
(or may become issuable assuming all possible market conditions) upon the exercise of any such Options or upon conversion, exercise
or exchange of any Convertible Securities issuable upon exercise of any such Option or otherwise pursuant to the terms thereof
minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting , issuance
or sale (or the agreement to grant, issue or sell, as applicable) of such Option, upon exercise of such Option and upon conversion,
exercise or exchange of any Convertible Security issuable upon exercise of such Option or otherwise pursuant to the terms thereof
plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Option (or any
other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance
of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or otherwise pursuant to the
terms of or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible
Securities.

(ii)
Issuance of Convertible Securities. If the Company in any manner issues or sells (or enters into any agreement to issue
or sell) any Convertible Securities and the lowest price per share for which one share of Common Stock is at any time issuable
upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof is less than the Applicable Price,
then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time
of the issuance or sale (or the time of execution of such agreement to issue or sell, as applicable) of such Convertible Securities
for such price per share. For the purposes of this Section 2(b)(ii), the “lowest price per share for which one share of
Common Stock is at any time issuable upon the conversion, exercise or exchange thereof or otherwise pursuant to the terms thereof”
shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to one share of Common Stock upon the issuance or sale (or pursuant to the agreement to issue or sell, as applicable)
of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security or otherwise pursuant to the
terms thereof and (y) the lowest conversion price set forth in such Convertible Security for which one share of Common Stock is
issuable (or may become issuable assuming all possible market conditions) upon conversion, exercise or exchange thereof or otherwise
pursuant to the terms thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or
any other Person) upon the issuance or sale (or the agreement to issue or sell, as applicable) of such Convertible Security plus
the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security
(or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual
issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities or otherwise pursuant
to the terms thereof, and if any such issuance or sale of such Convertible Securities is made upon exercise of any Options for
which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(b), except as contemplated
below, no further adjustment of the Exercise Price shall be made by reason of such issuance or sale.








 


(iii)
Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional
consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases
at any time (other than proportional changes in conversion or exercise prices, as applicable, in connection with an event referred
to in Section 2(a)), the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price
which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased
purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially
granted, issued or sold. For purposes of this Section 2(b)(iii), if the terms of any Option or Convertible Security that was outstanding
as of the Subscription Date are increased or decreased in the manner described in the immediately preceding sentence, then such
Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall
be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(b) shall be
made if such adjustment would result in an increase of the Exercise Price then in effect.


 






    	10



     


    

 


(iv)
Calculation of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection
with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the
“Primary Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary
Securities”), together comprising one integrated transaction, (or one or more transactions if such issuances or sales
or deemed issuances or sales of securities of the Company either (A) have at least one investor or purchaser in common, (B) are
consummated in reasonable proximity to each other and/or (C) are consummated under the same plan of financing) the aggregate consideration
per share of Common Stock with respect to such Primary Security shall be deemed to be equal to the difference of (x) the lowest
price per share for which one share of Common Stock was issued (or was deemed to be issued pursuant to Section 2(b)(i) or 2(b)(ii)
above, as applicable) in such integrated transaction solely with respect to such Primary Security, minus (y) with respect to such
Secondary Securities, the sum of (I) the Black Scholes Consideration Value of each such Option, if any, (II) the fair market value
(as determined by the Holder in good faith) or the Black Scholes Consideration Value, as applicable, of such Adjustment Right,
if any, and (III) the fair market value (as determined by the Holder) of such Convertible Security, if any, in each case, as determined
on a per share basis in accordance with this Section 2(b)(iv). If any shares of Common Stock, Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor (for the purpose of determining
the consideration paid for such Common Stock, Option or Convertible Security, but not for the purpose of the calculation of the
Black Scholes Consideration Value) will be deemed to be the net amount of consideration received by the Company therefor. If any
shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of
such consideration received by the Company (for the purpose of determining the consideration paid for such Common Stock, Option
or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be the fair
value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount
of consideration received by the Company for such securities will be the arithmetic average of the VWAPs of such security for
each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible
Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving
entity, the amount of consideration therefor (for the purpose of determining the consideration paid for such Common Stock, Option
or Convertible Security, but not for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to
be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares
of Common Stock, Options or Convertible Securities (as the case may be). The fair value of any consideration other than cash or
publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement
within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair
value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following such
Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such
appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall
be borne by the Company.


 




    	11



     


    

 


(v)
Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A)
to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to
subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be
the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the
case may be).


 


(c)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Section 2 above, 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).


 


(d)
Holder’s Right of Alternative Exercise Price Following Issuance of Certain Options or Convertible Securities. In
addition to and not in limitation of the other provisions of this Section 2, if the Company in any manner issues or sells or enters
into any agreement to issue or sell, any Common Stock, Options or Convertible Securities (any such securities, “Variable
Price Securities”) after the Subscription Date that are issuable pursuant to such agreement or convertible into or exchangeable
or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock,
including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary anti-dilution
provisions (such as share splits, share combinations, share dividends and similar transactions) (each of the formulations for
such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice
thereof via facsimile, electronic mail and overnight courier to the Holder on the date of such agreement and the issuance of such
Convertible Securities or Options. From and after the date the Company enters into such agreement or issues any such Variable
Price Securities, the Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price
for the Exercise Price upon exercise of this Warrant by designating in the Exercise Notice delivered upon any exercise of this
Warrant that solely for purposes of such exercise the Holder is relying on the Variable Price rather than the Exercise Price then
in effect. The Holder’s election to rely on a Variable Price for a particular exercise of this Warrant shall not obligate
the Holder to rely on a Variable Price for any future exercises of this Warrant.


 


(e)
Stock Combination Event Adjustment. If at any time and from time to time on or after the Issuance Date there occurs any
stock split, stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each,
a “Stock Combination Event”, and such date thereof, the “Stock Combination Event Date”)
and the Event Market Price is less than the Exercise Price then in effect (after giving effect to the adjustment in clause 2(a)
above), then on the sixteenth (16th) Trading Day immediately following such Stock Combination Event, the Exercise Price then in
effect on such sixteenth (16th) Trading Day (after giving effect to the adjustment in clause 2(a) above) shall be reduced (but
in no event increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence
would otherwise result in an increase in the Exercise Price hereunder, no adjustment shall be made.


 




    	12



     


    

 


(f)
Other Events. In the event that the Company (or any Subsidiary (as defined in the Securities Purchase 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 (other than with respect to Excluded Securities) 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 stock appreciation
rights, phantom stock 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(f) 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.


 


(g)
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.


 


(h)
Voluntary Adjustment By Company. Subject to the rules and regulations of the Principal Market, the Company may at any time
during the term of this Warrant, with the prior written consent of the Required Holders (as defined in the Securities Purchase
Agreement), 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.


 


(i)
Floor Price. Notwithstanding the foregoing, at any time prior to the Transaction Shareholder Approval Date (as defined
in the Securities Purchase Agreement), no adjustment pursuant to this Section 2 shall cause the Exercise Price to be less than
$2.782 (as adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction occurring
after the Subscription Date) (the “Floor Price”); provided, that on the Transaction Shareholder Approval Date,
any adjustment to the Exercise Price that would have occurred prior to the Transaction Shareholder Approval Date, but for the
existence of this Section 2(i), shall automatically adjust the Exercise Price of this Warrant, effective as of the Transaction
Shareholder Approval Date, as if such adjustment occurred on the date of such Dilutive Issuance and this Section 2(i) didn’t
exist as of such date of determination.


 






    	13



     


    

 


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 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 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 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).


 




    	14



     


    

 


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 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 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).


 






    	15



     


    

 


(b)
Fundamental Transactions. 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 its Parent Entity)
is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the consummation
of each Fundamental Transaction, 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, 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. Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect, at
its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction
without the assumption 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 an exercise of this Warrant at
any time after the consummation of the applicable Fundamental Transaction 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.


 




    	16



     


    

 


(c)
Black Scholes Value. Notwithstanding the foregoing and the provisions of Section 4(b) above, 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 ninety (90) 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 (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 Black Scholes Value.
Payment of such amounts shall be made by the Company (or at the Company’s direction) to the Holder on or prior to the later
of (x) the second (2nd) Trading Day after the date of such request and (y) the date of consummation of such Fundamental
Transaction.


 


(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 such other warrant)).


 


5.
NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Articles 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.


 






    	17



     


    

 


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 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 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.








 


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
with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.


 


(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.


 


(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.


 






    	18



     


    

 


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 fifteen (15) 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, (B) with respect to any grants, issuances or sales of any Options, Convertible
Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock or (C) 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 the consummation of any Fundamental Transaction. 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 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.
DISCLOSURE.
Upon delivery by the Company to the Holder (or receipt by the Company from the Holder) of any notice in accordance with the terms
of this Warrant, unless the Company has in good faith determined that the matters relating to such notice do not constitute material,
non-public information relating to the Company or any of its Subsidiaries, the Company shall on or prior to 9:00 am, New York
city time on the Business Day immediately following such notice delivery date publicly disclose such material, non-public information
on a Current Report on Form 8-K or otherwise. In the event that the Company believes that a notice contains material, non-public
information relating to the Company or any of its Subsidiaries, the Company so shall indicate to the Holder explicitly in writing
in such notice (or immediately upon receipt of notice from the Holder, as applicable), and in the absence of any such written
indication in such notice (or notification from the Company immediately upon receipt of notice from the Holder), the Holder shall
be entitled to presume that information contained in the notice does not constitute material, non-public information relating
to the Company or any of its Subsidiaries.

11.
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. No consideration (other than reimbursement of legal fees) shall be offered or paid to any Person to amend
or consent to a waiver or modification of any provision of any of the Registered Warrants unless the same consideration also is
offered to all of the holders of the Registered Warrants. From the date hereof and while any Registered Warrants are outstanding,

applicable, or (ii) to treat holder(s) of Registered Warrants in a manner that is less favorable than the holder of Registered

has been treated more or less favorably than another holder of Registered Warrants shall disregard any securities of the Company
purchased or sold by any holder of Registered Warrants.








 


12.
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).

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

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
