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 (or e-mail attachment) 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. No ink-original
Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice
of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been
exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within five (5) 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 two (2) Business Days of receipt of such notice. The Holder and
any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following
the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any
given time may be less than the amount stated on the face hereof.


 


b)
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $_______1,
subject to adjustment hereunder (the “Exercise Price”).


 


c)
Cashless Exercise. If at any time on or after the Initial Exercise Date, there is no effective registration statement registering,
or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may
also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be
entitled to receive the 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.



 


If
Warrant Shares are issued in such a “cashless exercise,” the parties acknowledge and agree that in accordance with
Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised,
and the holding period of the Warrants being exercised may be tacked on to the holding period of the Warrant Shares.  The
Company agrees not to take any position contrary to this Section 2(c). 


 





 






1
125% of the public offering price per share of common stock and warrant in the offering.


 




    3


     


    

 


 Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant
to this Section 2(c).


 


d)
Mechanics of Exercise.


 


i.
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted
by its transfer agent to the Holder by crediting the account of the Holder’s or its designee’s balance account 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 Holder, or (B) the Warrant Shares are eligible for resale by the Holder without
volume or manner-of-sale limitations pursuant to Rule 144 and, in either case, the Warrant Shares have been sold by the Holder
prior to the Warrant Share Delivery Date (as defined below), and otherwise by physical delivery of a certificate, registered in
the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder
is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is two
(2) Trading Days after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery
Date”). If the Warrant Shares can be delivered via DWAC, the transfer agent shall have received from the Company, at
the expense of the Company, any legal opinions or other documentation required by it to deliver such Warrant Shares without legend
(subject to receipt by the Company of reasonable back up documentation from the Holder, including with respect to affiliate status)
and, if applicable and requested by the Company prior to the Warrant Share Delivery Date, the transfer agent shall have received
from the Holder a confirmation of sale of the Warrant Shares (provided the requirement of the Holder to provide a confirmation
as to the sale of Warrant Shares shall not be applicable to the issuance of unlegended Warrant Shares upon a cashless exercise
of this Warrant if the Warrant Shares are then eligible for resale pursuant to Rule 144(b)(1)). 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. If the Company fails for any reason to deliver to the Holder the Warrant
Shares subject to a Notice of Exercise by the second Trading Day following the Warrant Share Delivery Date, the Company shall pay
to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise
(based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20
per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after the second Trading
Day following such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise.


    


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 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.


 




    4


     


    

 


iii.
Rescission Rights. If the Company fails to cause its transfer agent to deliver to the Holder the Warrant Shares pursuant
to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise; provided,
however, that the Holder shall be required to return any Warrant Shares or Common Stock subject to any such rescinded exercise
notice concurrently with the return to Holder of the aggregate Exercise Price paid to the Company for such Warrant Shares and the
restoration of Holder’s right to acquire such Warrant Shares pursuant to this Warrant (including, issuance of a replacement
warrant certificate evidencing such restored right).


 


iv.
Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available
to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder 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 shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.


 




    5


     


    

 


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 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 Warrant Shares, all of which taxes and expenses shall be paid
by the Company, and such Warrant Shares 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 that 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
and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required
for same-day electronic delivery of the Warrant Shares.


 


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.


 


viii.
Signature. This Section 2 and the exercise form attached hereto set forth the totality of the procedures required of the
Holder in order to exercise this Purchase Warrant.  Without limiting the preceding sentences, no ink-original exercise form
shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any exercise form be required
in order to exercise this Purchase Warrant.  No additional legal opinion, other information or instructions shall be required
of the Holder to exercise this Purchase Warrant.  The Company shall honor exercises of this Purchase Warrant and shall deliver
Shares underlying this Purchase Warrant in accordance with the terms, conditions and time periods set forth herein.


 




    6


     


    

 


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 Company’s 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 9.99% 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, upon notice to the Company,
may increase or decrease 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 increase in the Beneficial Ownership Limitation 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. 


 




    7


     


    

  


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), (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.
For the purposes of clarification, the Exercise Price of this Warrant will not be adjusted in the event that the Company or any
Subsidiary thereof, as applicable, sells or grants any option to purchase, or sell or grant any right to reprice, or otherwise
dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common
Stock Equivalents, at an effective price per share less than the Exercise Price then in effect.


 


b)
[RESERVED]


  


c)
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).


 


d)
Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend
(other than cash dividends) 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 shares or other securities,
property or options 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 on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date
of 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, to the extent
that the Holder's right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation,
then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any
shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance
for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation). To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution,
such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.


 




    8


     


    

  


e)
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 by holders of Common Stock as a result of such Fundamental Transaction
for each share 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 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 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 with the same effect as if such
Successor Entity had been named as the Company herein.


 




    9


     


    

 


f)  
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.


 


g)
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, cash or property, 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, the Company shall cause to be mailed a notice 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, 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 provide such notice or any defect therein 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

Section 4. Transfer
of Warrant.


 


a)
Transferability. Pursuant to FINRA Rule 5110(g)(1), neither this Warrant nor any Warrant Shares issued upon exercise of
this Warrant shall be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative,
put, or call transaction that would result in the effective economic disposition of the securities by any person for a period of
180 days immediately following the date of effectiveness or commencement of sales of the offering pursuant to which this Warrant
is being issued, except the transfer of any security:


 


i.
by operation of law or by reason of reorganization of the Company;


 


ii.
to any FINRA member firm participating in the offering and the officers or partners thereof, if all securities so transferred remain
subject to the lock-up restriction in this Section 4(a) for the remainder of the time period;


 


iii.
if the aggregate amount of securities of the Company held by the Holder or related person do not exceed 1% of the securities being
offered;


 


iv.
that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member
manages or otherwise directs investments by the fund, and participating members in the aggregate do not own more than 10% of the
equity in the fund; or


 


v.
the exercise or conversion of any security, if all securities received remain subject to the lock-up restriction in this Section
4(a) for the remainder of the time period.


  


Subject to
the foregoing restriction, any applicable securities laws and the conditions set forth in Section 4(d), 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. Notwithstanding anything herein to the contrary, the Holder shall not be required
to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder
shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to
the Company assigning this Warrant full. 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.


 




    11


     


    

 


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.


 


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


 


Section 5.
Registration Rights.


 


5.1 Demand
Registration.


 


5.1.1
Grant of Right. The Company, upon written demand (a “Demand Notice”) of the Holder(s) of at least 51% of the
Warrants and/or Warrant Shares (“Majority Holders”), agrees to register, on one occasion, all or any
portion of the Warrant Shares underlying the Warrants (collectively, the “Registrable Securities”). On such
occasion, the Company will file a registration statement with the Commission on Form S-3 when available covering the
Registrable Securities within sixty (60) days after receipt of a Demand Notice and use its reasonable best efforts to have
the registration statement declared effective promptly thereafter, subject to compliance with review by the Commission;
provided, however, that the Company shall not be required to comply with a Demand Notice if the Company has filed a
registration statement with respect to which the Holder is entitled to piggyback registration rights pursuant to Section 5.2
hereof and either: (i) the Holder has elected to participate in the offering covered by such registration statement or (ii)
if such registration statement relates to an underwritten primary offering of securities of the Company, until the offering
covered by such registration statement has been withdrawn or until thirty (30) days after such offering is consummated. The
demand for registration may be made at any time during a period of four (4) years beginning on the Initial Exercise Date. The
Company covenants and agrees to give written notice of its receipt of any Demand Notice by any Holder(s) to all other
registered Holders of the Warrants and/or the Registrable Securities within ten (10) days after the date of the receipt of
any such Demand Notice.


 




    12


     


    

 


5.1.2 Terms.
The Company shall bear all fees and expenses attendant to the registration of the Registrable Securities pursuant to Section 5.1.1,
but the Holders shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Holders to
represent them in connection with the sale of the Registrable Securities. The Company agrees to use its reasonable best efforts
to cause the filing required herein to become effective promptly and to qualify or register the Registrable Securities in such
States as are reasonably requested by the Holder(s); provided, however, that in no event shall the Company be required to register
the Registrable Securities in a State in which such registration would cause: (i) the Company to be obligated to register or license
to do business in such State or submit to general service of process in such State, or (ii) the principal shareholders of the Company
to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any registration statement filed
pursuant to the demand right granted under Section 5.1.1 to remain effective for a period of at least twelve (12) consecutive months
after the date that the Holders of the Registrable Securities covered by such registration statement are first given the opportunity
to sell all of such securities. The Holders shall only use the prospectuses provided by the Company to sell the Warrant Shares
covered by such registration statement, and will immediately cease to use any prospectus furnished by the Company if the Company
advises the Holder that such prospectus may no longer be used due to a material misstatement or omission. Notwithstanding the provisions
of this Section 5.1.2, the Holder shall be entitled to a demand registration under this Section 5.1.2 on only one (1) occasion
and such demand registration right shall terminate on the fifth anniversary of the date of the Underwriting Agreement (as defined
below) in accordance with FINRA Rule 5110(f)(2)(G)(iv).


 


5.2 “Piggy-Back”
Registration.


 


5.2.1
Grant of Right. In addition to the demand right of registration described in Section 5.1 hereof, the Holder shall have the
right, for a period of no more than two (2) years from the Initial Exercise Date in accordance with FINRA Rule
5110(f)(2)(G)(v), to include the Registrable Securities as part of any other registration of securities filed by the Company
(other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to
Form S-8 or any equivalent form); provided, however, that if, solely in connection with any primary underwritten public
offering for the account of the Company, the managing underwriter(s) thereof shall, in its reasonable discretion, impose a
limitation on the number of Shares which may be included in the Registration Statement because, in such underwriter(s)’
judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company
shall be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with
respect to which the Holder requested inclusion hereunder as the underwriter shall reasonably permit. Any exclusion of
Registrable Securities shall be made pro rata among the Holders seeking to include Registrable Securities in proportion to
the number of Registrable Securities sought to be included by such Holders; provided, however, that the Company shall not
exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are
not entitled to inclusion of such securities in such Registration Statement or are not entitled to pro rata inclusion with
the Registrable Securities.


 




    13


     


    

 


5.2.2 Terms.
The Company shall bear all fees and expenses attendant to registering the Registrable Securities pursuant to Section 5.2.1 hereof,
but the Holders shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Holders to
represent them in connection with the sale of the Registrable Securities. In the event of such a proposed registration, the Company
shall furnish the then Holders of outstanding Registrable Securities with not less than thirty (30) days written notice prior to
the proposed date of filing of such registration statement. Such notice to the Holders shall continue to be given for each registration
statement filed by the Company during the two (2) year period following the Initial Exercise Date until such time as all of the
Registrable Securities have been sold by the Holder. The holders of the Registrable Securities shall exercise the “piggy-back”
rights provided for herein by giving written notice within ten (10) days of the receipt of the Company’s notice of its intention
to file a registration statement. Except as otherwise provided in this Warrant, there shall be no limit on the number of times
the Holder may request registration under this Section 5.2.2; provided, however, that such registration rights shall terminate
on the second anniversary of the Initial Exercise Date.


 


5.3 General
Terms


 


5.3.1          Indemnification.
The Company shall indemnify the Holder(s) of the Registrable Securities to be sold pursuant to any registration statement hereunder
and each person, if any, who controls such Holders within the meaning of Section 15 of the Securities Act or Section 20 (a) of
the Exchange Act against all loss, claim, damage, expense or liability (including all reasonable attorneys’ fees and other
expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which any of them may become
subject under the Securities Act, the Exchange Act or otherwise, arising from such registration statement but only to the same
extent and with the same effect as the provisions pursuant to which the Company has agreed to indemnify the Underwriters contained
in Section 5.1 of the Underwriting Agreement between the Underwriters and the Company, dated as of [___], 2019. The Holder(s) of
the Registrable Securities to be sold pursuant to such registration statement, and their successors and assigns, shall severally,
and not jointly, indemnify the Company, against all loss, claim, damage, expense or liability (including all reasonable attorneys’
fees and other expenses reasonably incurred in investigating, preparing or defending against any claim whatsoever) to which they
may become subject under the Securities Act, the Exchange Act or otherwise, arising from information furnished by or on behalf
of such Holders, or their successors or assigns, in writing, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 5.2 of the Underwriting Agreement pursuant to which the
Underwriters have agreed to indemnify the Company.


 


5.3.2 Exercise
of Warrants. Nothing contained in this Warrant shall be construed as requiring the Holder(s) to exercise their Warrants prior to
or after the initial filing of any registration statement or the effectiveness thereof.


 


5.3.3 Documents
Delivered to Holders. The Company shall furnish to each Holder participating in any of the foregoing offerings and to each underwriter
of any such offering, if any, a signed counterpart, addressed to such Holder or underwriter, of: (i) an opinion of counsel to the
Company, dated the effective date of such registration statement (and, if such registration includes an underwritten public offering,
an opinion dated the date of the closing under any underwriting agreement related thereto), and (ii) a “cold comfort”
letter dated the effective date of such registration statement (and, if such registration includes an underwritten public offering,
a letter dated the date of the closing under the underwriting agreement) signed by the independent registered public accounting
firm which has issued a report on the Company’s financial statements included in such registration statement, in each case
covering substantially the same matters with respect to such registration statement (and the prospectus included therein) and,
in the case of such accountants’ letter, with respect to events subsequent to the date of such financial statements, as are
customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to underwriters in underwritten
public offerings of securities. The Company shall also deliver promptly to each Holder participating in the offering requesting
the correspondence and memoranda described below and to the managing underwriter, if any, copies of all correspondence between
the Commission and the Company, its counsel or auditors and all memoranda relating to discussions with the Commission or its staff
with respect to the registration statement and permit each Holder and underwriter to do such investigation, upon reasonable advance
notice, with respect to information contained in or omitted from the registration statement as it deems reasonably necessary to
comply with applicable securities laws or rules of FINRA. Such investigation shall include access to books, records and properties
and opportunities to discuss the business of the Company with its officers and independent auditors, all to such reasonable extent
and at such reasonable times as any such Holder shall reasonably request.


 




    14


     


    

 


5.3.4 Underwriting
Agreement. The Company shall enter into an underwriting agreement with the managing underwriter(s), if any, selected by any Holders
whose Registrable Securities are being registered pursuant to this Section 5, which managing underwriter shall be reasonably satisfactory
to the Company. Such agreement shall be reasonably satisfactory in form and substance to the Company, each Holder and such managing
underwriters, and shall contain such representations, warranties and covenants by the Company and such other terms as are customarily
contained in agreements of that type used by the managing underwriter. The Holders shall be parties to any underwriting agreement
relating to an underwritten sale of their Registrable Securities and may, at their option, require that any or all the representations,
warranties and covenants of the Company to or for the benefit of such underwriters shall also be made to and for the benefit of
such Holders. Such Holders shall not be required to make any representations or warranties to or agreements with the Company or
the underwriters except as they may relate to such Holders, their Warrant Shares and their intended methods of distribution.


 


5.3.5 Documents
to be Delivered by Holder(s). Each of the Holder(s) participating in any of the foregoing offerings shall furnish to the Company
a completed and executed questionnaire provided by the Company requesting information customarily sought of selling security holders.


 


5.3.6 Damages.
Should the registration or the effectiveness thereof required by Sections 5.1 and 5.2 hereof be delayed by the Company or the Company
otherwise fails to comply with such provisions, the Holder(s) shall, in addition to any other legal or other relief available to
the Holder(s), be entitled to obtain specific performance or other equitable (including injunctive) relief against the threatened
breach of such provisions or the continuation of any such breach, without the necessity of proving actual damages and without the
necessity of posting bond or other security.


 




    15


     


    

 


Section 6. 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 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 issuing the necessary 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 nonassessable and free from all taxes, liens and charges created by
the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such
issue).


 


Except and
to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending
its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions
as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting
the generality of the foregoing, the Company will (i) 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.


 




    16


     


    

 


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 underwriting agreement, dated July [ ] 2019, by and between the Company
and ThinkEquity, a division of Fordham Financial Management, Inc., as representatives of the underwriters set forth therein (the
“Underwriting Agreement”).


 


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


 


g)
Nonwaiver 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 Underwriting 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 Underwriting 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.


 




    17


     


    

 


l) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the
Holder.


 


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.
