FORM OF CLASS B
COMMON STOCK PURCHASE WARRANT


 


NXT-ID,
INC.


 


	Warrant Shares: [_____________]	Issuance Date: April 24, 2015




 


Warrant No: [__________]


 


THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received, [__________] or its assigns (the “Holder”)
is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on
or after the six month anniversary of the date hereof (the “Initial Exercise Date”) and on or prior to the close
of business on the five (5) year anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter,
to subscribe for and purchase from NXT-ID, INC., a Delaware corporation (the “Company”), up to [______]
shares (as subject to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one
share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).


 


Section 1.          Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement
(the “Purchase Agreement”), dated April 24, 2015, among the Company and the purchasers signatory thereto.


 


Section 2.          Exercise.


 


a)        Exercise of the purchase
rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date
and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate
by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed
facsimile copy of the Notice of Exercise Form annexed hereto. Within two (2) Trading Days following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer
or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below
is specified in the applicable Notice of Exercise. Notwithstanding anything herein to the contrary (although the Holder may surrender
the Warrant to, and receive a replacement Warrant from, the Company), the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been
exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading
Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases
of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number
of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and
the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company
shall deliver any objection to any Notice of Exercise Form within one (1) Trading Day of delivery of such notice. The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following
the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any
given time may be less than the amount stated on the face hereof.


 






    	1



    	 



    

 


b)        Exercise
Price. The initial exercise price per share of the Common Stock under this Warrant shall be $5.00, subject to adjustment
hereunder (the “Exercise Price”).


 


c)        Cashless
Exercise. If at any time after the Initial Exercise Date, there is no effective Registration Statement registering, or no
current prospectus available for the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised at the
Holder’s election, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall
be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A) = the VWAP
on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless
exercise,” as set forth in the applicable Notice of Exercise;


 


(B) = the Exercise
Price of this Warrant, as adjusted hereunder; and


 


(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.


 


Notwithstanding anything
herein to the contrary, on the Termination Date, unless the Holder notifies the Company otherwise, if there is no effective Registration
Statement registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant
shall be automatically exercised via cashless exercise pursuant to this Section 2(c).

d)           Mechanics of Exercise.


 


i.     Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the
Transfer Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through
its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system
and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the
Warrant Shares by the Holder or (B) this Warrant is being exercised via cashless exercise and Rule 144 is available, and otherwise
by physical delivery to the address specified by the Holder in the Notice of Exercise by the date that is three (3) Trading Days
after the latest of (A) the delivery to the Company of the Notice of Exercise, (B) surrender of this Warrant (if required) and
(C) payment of the aggregate Exercise Price as set forth above (including by cashless exercise, if permitted) (such date, the
“Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and Holder or any other
person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as
of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted)
and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having
been paid. The Company understands that a delay in the delivery of the Warrant Shares after the Warrant Share Delivery Date could
result in economic loss to the Holder. As compensation to the Holder for such loss, the Company agrees to pay (as liquidated damages
and not as a penalty) to the Holder for late issuance of Warrant Shares upon exercise of this Warrant the proportionate amount
of $10 per Trading Day (increasing to $20 per Trading Day after the fifth (5th) Trading Day) after the Warrant Share
Delivery Date for each $1,000 of Exercise Price of Warrant Shares for which this Warrant is exercised which are not timely delivered.
The Company shall pay any payments incurred under this Section in immediately available funds upon demand. Furthermore, in addition
to any other remedies which may be available to the Holder, in the event that the Company fails for any reason to effect delivery
of the Warrant Shares by the Warrant Share Delivery Date, the Holder may revoke all or part of the relevant Warrant exercise by
delivery of a notice to such effect to the Company, whereupon the Company and the Holder shall each be restored to their respective
positions immediately prior to the exercise of the relevant portion of this Warrant, except that the liquidated damages described
above shall be payable through the date notice of revocation or rescission is given to the Company.


 


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


 


iii.     Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing
the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right, at any
time prior to issuance of such Warrant Shares, to rescind such exercise.


 



    	3



    	 



    

 


iv.     Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights
available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates
representing the Warrant Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the
Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm
otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the
Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the
Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for
the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the
Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order
giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the
Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be
deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely
complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate
sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company
shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall
limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates
representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.


 


v.     No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the
Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction
multiplied by the Exercise Price or round up to the next whole share.


 


vi.     Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder
for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and
expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names
as may be directed by the Holder; provided, however, that in the event certificates for Warrant Shares are to be
issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment
Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient
to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing
of any Notice of Exercise.


 


vii.     Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely
exercise of this Warrant, pursuant to the terms hereof.


 






    	4



    	 



    

  


e)        Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall
not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving
effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates), would beneficially
own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number
of shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock
issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of
shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially
owned by the Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any
other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. 
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder
that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act
and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion
of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion
of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation
to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above
shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number
of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with
the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by
the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.  Upon the written or oral
request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder the number of shares
of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be determined after
giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates
since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation”
shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares
of Common Stock issuable upon exercise of this Warrant. The Holder may decrease the Beneficial Ownership Limitation at any time
and the Holder, upon not less than 61 days’ prior notice to the Company, may increase the Beneficial Ownership Limitation
provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares
of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this
Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any such increase will not be effective
until the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed
and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or
to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in
this paragraph shall apply to a successor holder of this Warrant.


 


Section 3.          Certain
Adjustments.


 


a)        Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company
upon exercise of this Warrant or pursuant to any of the other Transaction Documents), (ii) subdivides outstanding shares of Common
Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock
into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of
the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number
of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator
shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon
exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain
unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination
of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date
in the case of a subdivision, combination or re-classification.


 






    	5



    	 



    

 


b)        Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company
grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata
to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be
entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have
acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without
regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before
the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the
date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in
the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase
Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent)
and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto
would not result in the Holder exceeding the Beneficial Ownership Limitation).


 


c)        Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders
of Common Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or
warrants to subscribe for or purchase any security other than the Common Stock (which shall be subject to Section 3(c)), then in
each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record
date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall
be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date
less the then per share fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed
applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed
or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution
is made and shall become effective immediately after the record date mentioned above.


 



    	6



    	 



    

 


d)        Fundamental Transaction. 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,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, 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 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 2(e) 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 2(e) 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. 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
3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without
unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange
for this 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


 


e)        Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of
a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding
as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.


 



    	7



    	 



    

 


f)           Notice to Holder.


 


i.     Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall
promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the
number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.


 


ii.     Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares
of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer
of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted
into other securities, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up
of the affairs of the Company, then, in each case, to the extent that such information constitutes material non-public information
(as determined in good faith by the Company) the Company shall follow the procedure described in Section 13 of the Subscription
Agreement and shall deliver to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at
least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is
not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the
Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice
or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding
the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current
Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such
notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.


 


Section 4.          Transfer
of Warrant.


 


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

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


 


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


 


Section 5.          Miscellaneous.


 


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


 


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


 


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

d)        Authorized Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve from
its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the
exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary
certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such
reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of
any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company
covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will,
upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be
duly authorized, validly issued, fully paid and non-assessable and free from all taxes, liens and charges created by the Company
in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such
actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without
limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount
payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary
or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise
of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under
this Warrant. Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant
is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto,
as may be necessary from any public regulatory body or bodies having jurisdiction thereof.


 


e)        Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Purchase Agreement.


 


f)        Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, or unless exercised
in a cashless exercise when Rule 144 is available, and the Holder does not utilize cashless exercise, will have restrictions upon
resale imposed by state and federal securities laws.


 


g)        Non-waiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision
of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to
cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings,
incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.


 


h)        Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the
Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.


 


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

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


 


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


 


l)        Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the
Company and the Holders of not less than a majority of the outstanding Warrants issued pursuant to the Purchase Agreement.


 


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


 


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