(5) year anniversary of the date hereof (the “Warrant Exercise Term”), the Shares at the Exercise Price (each
as defined in Section 1 below).


 


This Warrant is subject
to the following terms and conditions:


 


1. Shares. The
Purchaser has, subject to the terms set forth herein, the right to purchase, at any time during the Warrant Exercise Term, up to
seven hundred fifty thousand (750,000) shares (the “Shares”) of the Company’s common stock, par value

Exercise Price is subject to adjustment as provided in Section 3 hereof.


 


2. Exercise of Warrant.


 


(a) Exercise.
This Warrant may be exercised by the Purchaser at any time during the Warrant Exercise Term, in whole or in part, by delivering
the notice of exercise attached as Exhibit A hereto (the “Notice of Exercise”), duly executed by the
Purchaser to the Company at its principal office, or at such other office as the Company may designate, accompanied by payment,
in cash or by wire transfer of immediately available funds or by check payable to the order of the Company, of the amount obtained
by multiplying the number of Shares designated in the Notice of Exercise by the Exercise Price (the “Purchase Price”).
For purposes hereof, “Exercise Date” shall mean the date on which all deliveries required to be made to the
Company upon exercise of this Warrant pursuant to this Section 2(a) shall have been made.


 



     


     


    

 


(b) Issuance of Certificates.
As soon as practicable after the exercise of this Warrant, in whole or in part, in accordance with Section 2(a) hereof, the Company,
at its expense, shall cause to be issued in the name of and delivered to the Purchaser (i) a certificate or certificates for the
number of validly issued, fully paid and non-assessable Shares to which the Purchaser shall be entitled upon such exercise and,
if applicable, (ii) a new warrant of like tenor to purchase all of the Shares that may be purchased pursuant to the portion, if
any, of this Warrant not exercised by the Purchaser. The Purchaser shall for all purposes hereof be deemed to have become the Purchaser
of record of such Shares on the date on which the Notice of Exercise and payment of the Purchase Price in accordance with Section
2(a) hereof were delivered and made, respectively, irrespective of the date of delivery of such certificate or certificates, except
that if the date of such delivery, notice and payment is a date when the stock transfer books of the Company are closed, such person
shall be deemed to have become the holder of record of such Shares at the close of business on the next succeeding date on which
the stock transfer books are open.


 


(c) Taxes. The
issuance of the Shares upon the exercise of this Warrant, and the delivery of certificates or other instruments representing such
Shares, shall be made without charge to the Purchaser for any tax or other charge of whatever nature in respect of such issuance
and the Company shall bear any such taxes in respect of such issuance.


 


(d) Notwithstanding anything
to the contrary herein, the commencement of the Warrant Exercise Term shall accelerate in full upon a Change of Control of the
Company. For purposes of this Warrant, a “Change of Control of the Company” shall be deemed to have occurred
if: (i) any person (including any individual, firm, partnership or other entity) together with all Affiliates and Associates (as
defined under Rule 12b-2 of the General Rules and Regulations promulgated under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”)) of such person (but excluding (A) a trustee or other fiduciary holding securities under
an employee benefit plan of the Company or any subsidiary of the Company, (B) a corporation or other entity owned, directly or
indirectly, by the equity holders of the Company in substantially the same proportions as their ownership of the Company (a “Similarly
Owned Company”) or (C) the Company or any subsidiary of the Company) first becomes the Beneficial Owner (as defined in
Rule 13d-3 promulgated under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50%
of the combined voting power of the Company’s then outstanding securities; (ii) the consummation of a merger or consolidation
of the Company with any other corporation or other entity, other than a merger or consolidation that would result in the voting
securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by
being converted into voting securities of the surviving entity) 50% or more of the combined voting power of the voting securities
of the Company or such surviving entity outstanding immediately after such merger or consolidation; or (iii) the consummation a
plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially
all of the Company’s assets to a person or persons that is not or are not a Similarly Owned Company. In no instance shall
a public or private offering of the Company’s securities that is primarily for capital raising purposes or compensatory purposes
be deemed to constitute a Change of Control of the Company.

3. Adjustment of
Exercise Price and Number of Shares.


 


(a) Adjustment for
Reclassification, Consolidation or Merger. If while this Warrant, or any portion hereof, remains outstanding and unexpired
there shall be (i) a reorganization or recapitalization (other than a combination, reclassification, exchange or subdivision of
shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation or other
entity in which the Company shall not be the surviving entity, or a reverse merger in which the Company shall be the surviving
entity but the shares of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue
of the merger into other property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s
properties and assets as, or substantially as, an entirety to any other corporation or other entity in one transaction or a series
of related transactions, then, as a part of such reorganization, recapitalization, merger, consolidation, sale or transfer, unless
otherwise directed by the Purchaser, all necessary or appropriate lawful provisions shall be made so that the Purchaser shall thereafter
be entitled to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price
then in effect, the greatest number of shares of capital stock or other securities or property that a holder of the Shares deliverable
upon exercise of this Warrant would have been entitled to receive in such reorganization, recapitalization, merger, consolidation,
sale or transfer if this Warrant had been exercised immediately prior to such reorganization, recapitalization, merger, consolidation,
sale or transfer, all subject to further adjustment as provided in this Section 3. If the per share consideration payable to the
Purchaser for Shares in connection with any such transaction is in a form other than cash or marketable securities, then the value
of such consideration shall be determined in good faith by the Company’s Board of Directors. The foregoing provisions of
this paragraph shall similarly apply to successive reorganizations, recapitalizations, mergers, consolidations, sales and transfers
and to the capital stock or securities of any other corporation that are at the time receivable upon the exercise of this Warrant.
In all events, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights
and interests of the Purchaser after the transaction, to the end that the provisions of this Warrant shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other property deliverable or issuable after such reorganization,
recapitalization, merger, consolidation, sale or transfer upon exercise of this Warrant.


 


(b) Adjustments for
Split, Subdivision or Combination of Shares. If the Company shall at any time subdivide (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock subject to acquisition hereunder, then,
after the date of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will
be proportionately reduced and the number of shares of Common Stock subject to acquisition upon exercise of the Warrant will be
proportionately increased. If the Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification
or otherwise) the shares of Common Stock subject to acquisition hereunder, then, after the record date for effecting such combination,
the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of shares of
Common Stock subject to acquisition upon exercise of the Warrant will be proportionately decreased.


 


(c) Adjustments for
Dividends in Stock or Other Securities or Property. If while this Warrant, or any portion hereof, remains outstanding and unexpired,
the holders of any class of securities as to which purchase rights under this Warrant exist at the time shall have received or,
on or after the record date fixed for the determination of eligible stockholders, shall have become entitled to receive, without
payment therefor, other or additional stock or other securities or property (other than cash) of the Company by way of dividend,
then and in each case, this Warrant shall represent the right to acquire, in addition to the number of shares of such class of
security receivable upon exercise of this Warrant, and without payment of any additional consideration therefor, the amount of
such other or additional stock or other securities or property (other than cash) of the Company that such holder would hold on
the date of such exercise had it been the holder of record of the class of security receivable upon exercise of this Warrant on
the date hereof and had thereafter, during the period from the date hereof to and including the date of such exercise, retained
such shares and/or all other additional stock available to it as aforesaid during said period, giving effect to all adjustments
called for during such period by the provisions of this Section 3.


 


(d) Notice of Adjustments.
Upon any adjustment of the Exercise Price and any increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Purchaser
at the address of such Purchaser as shown on the books of the Company, which notice shall state the Exercise Price as adjusted
and, if applicable, the increased or decreased number of Shares purchasable upon the exercise of this Warrant, setting forth in
reasonable detail the method of calculation of each.

4. NOTICE. Where this
Warrant provides for notice of any event, such notice shall be given (unless otherwise herein expressly provided) in writing and
either (a) delivered personally, (b) sent by certified, registered or express mail, postage prepaid or (c) sent by facsimile or
other electronic transmission, and shall be deemed given when so delivered personally, sent by facsimile or other electronic transmission
(confirmed in writing) or mailed. Notices shall be addressed, if to Purchaser, to its address as set forth in the books and records
of the Company from time to time or, if to the Company, to its principal office.


 


5. Legends.
Each certificate evidencing the Shares issued upon exercise of this Warrant shall be stamped or imprinted with a legend substantially
in the following form:

OF THE ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR
TO SUCH EFFECT, WHICH OPINION SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.


 


6. Removal of Legend.
Upon request of a holder of a certificate with the legends required by Section 5 hereof, the Company shall issue to such holder
a new certificate therefor free of any transfer legend, if, with such request, the Company shall have received an opinion of counsel
satisfactory to the Company in form and substance to the effect that any transfer by such holder of the Shares evidenced by such
certificate will not violate the Act or any applicable state securities laws.


 


7. Fractional Shares.
No fractional Shares will be issued in connection with any exercise hereunder. Instead, the Company shall round up, as nearly as
practicable to the nearest whole Share, the number of Shares to be issued. This Warrant may only be exercised for whole shares.


 


8. Rights of Stockholders.
Except as expressly provided in Section 3(c) hereof, the Purchaser, as such, shall not be entitled to vote or receive dividends
or be deemed the holder of the Shares or any other securities of the Company that may at any time be issuable on the exercise hereof
for any purpose, nor shall anything contained herein be construed to confer upon the Purchaser, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings,
or otherwise until this Warrant shall have been exercised and the Shares purchasable upon the exercise hereof shall have been issued,
as provided herein.

Rights.

transferees, by written notice at least 30 days prior to the filing of any registration statement or post-effective amendment thereto
under the Securities Act covering any securities of the Company, for its own account or for the account of others (other than a
registration statement on Form S-4 or S-8 or any successor forms thereto), and will, upon the request of the Purchaser, include
in any such post-effective amendment or registration statement, such information as may be required to permit a public offering
of, all or any of the Registrable Securities. The Company shall supply prospectuses and such other documents as the Purchaser may
reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities, use its reasonable
efforts to register and qualify any of the Registrable Securities for sale in such states as such Purchaser designates, provided
that the Company shall not be required to qualify as a foreign corporation or a dealer in securities or execute a general consent
to service of process in any jurisdiction in any action, and do any and all other acts and things which may be reasonably necessary
or desirable to enable such Purchaser to consummate the public sale or other disposition of the Registrable Securities (it being
understood that the Company, in its sole discretion, has the right not to request acceleration of effectiveness of any such registration
statement). The Purchaser shall promptly furnish all necessary information requested by the Company in connection with said registration
statement. The Company shall use its commercially reasonable efforts to cause the managing underwriter or underwriters of a proposed
underwritten offering to permit the Purchaser of Registrable Securities requested to be included in the registration statement.
Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering advises the Company or the Purchaser
of Registrable Securities that the total amount of securities which they intend to include in such offering is such as to adversely
affect the success of such offering, then the amount of securities to be offered for the accounts of Purchaser of Registrable Securities
shall be eliminated, reduced, or limited to the extent necessary to reduce the total amount of securities to be included in such
offering to the amount, if any, recommended by such managing underwriter or underwriters (which reduction or elimination shall
be pro rata with the reduction of, or consistent with the elimination of, all securities of other selling securityholders in the
registration statement) and shall be subject to (i) the number of securities which the Company proposes to offer and sell for its
own account in such offering and (ii) any other registration rights granted to other shareholders or securityholders of the Company
that are in effect on the date thereof (any such reduction or limitation in the total amount of Registrable Securities to be included
in such offering to be borne by the Purchaser of Registrable Securities proposed to be included therein pro rata). The Purchaser
will be responsible for and shall pay its own legal fees and expenses and any underwriting discounts and commissions and non-accountable
expense allowances on the securities sold by such Purchaser and shall not be responsible for any other expenses of such registration.


 



    6


     


    

 


(b) Notwithstanding
anything contained herein to the contrary, a Registrable Security shall cease to be Registrable Security (and the piggy-back registration
rights set forth in this Section 11 shall not apply) for so long as (a) a registration statement with respect to the sale of such
Registrable Securities is declared effective by the Securities and Exchange Commission under the Securities Act and such Registrable
Securities have been disposed of by the Purchaser in accordance with such effective registration statement, (b) such Registrable
Securities have been previously sold by the Participant in accordance with Rule 144 promulgated under the Securities Act, or (c)
such securities become eligible for resale without volume or manner-of-sale restrictions and without current public information
pursuant to Rule 144 or other exemption from registration as set forth in a written opinion letter of counsel to the Company to
such effect, addressed, delivered and acceptable to the transfer agent of the Company and the Purchaser.
