2.1.Exercise in Full.
Subject to the provisions hereof, this Warrant may be exercised in full by the Holder hereof by surrender of this Warrant, with
the form of subscription at the end hereof duly executed by such Holder, to the Company at its principal office accompanied by
payment, in cash or by certified or official bank check payable to the order of the Company, in the amount obtained by multiplying

Subject to the provisions hereof, this Warrant may be exercised in part by surrender of this Warrant in the manner and at the place
provided in Section 3.1 except that the amount payable by the Holder upon any partial exercise shall be the amount obtained by
multiplying (a) the number of shares of Warrant Shares (without giving effect to any adjustment therein) designated by the Holder

per share of the Underlying Securities on such date on any registered national stock exchange
on which the Underlying Securities is then listed, or if there is no such closing sales price
on such date, then the closing sales price on such exchange or quotation system on the date nearest preceding such date, or (b)

closing sales price for a share of Underlying Securities in
the over-the-counter market, as reported by the OTC Bulletin Board or the OTC Markets Group, Inc. (or similar organization or agency
succeeding to its functions of reporting prices) at the close of business on such date, or (c) if the Underlying Securities
is not then reported by the OTC Bulletin Board or the OTC Markets Group, Inc. (or similar organization
or agency succeeding to its functions of reporting prices), the fair market value of a share of Underlying Securities as
determined by the Board, acting in good faith. In determining the fair market value of any shares of Underlying Securities

2.5.Holder’s
Exercise Limitations. The Company shall not affect 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 Exercise Notice, 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 conversion
of the shares acquired 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) conversion of the shares acquirable upon 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 2.5, 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 2.5
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 form of subscription 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 2.5, 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 its 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 Business 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 potential issuance of shares of Common Stock issuable upon conversion of the shares acquired upon exercise of this
Warrant. The Holder, upon not less than 61 days’ prior written notice to the Company, may increase or decrease the Beneficial
Ownership Limitation provisions of this Section 2.5, 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 potential issuance of shares of Common
Stock issuable upon conversion of the shares acquired upon exercise of this Warrant held by the Holder and the provisions of this
Section 2.5 shall continue to apply.  Any such increase or decrease will not be effective until the 61st day after such
written 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 2.5 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. The Beneficial Ownership Limitation provisions of this Section 2.5 may be waived at the election of the
Holder upon not less than 61 days’ prior written notice to the Company. Any such waiver will not be effective and the provisions
of this paragraph shall continue to apply until the 61st day (or later, if stated in the notice) after such notice of waiver is
delivered to the Company. Unless earlier waived, the provisions of this Section 2.5 shall expire and be of no further force or
effect as of _________, 20__.

3.Delivery of Stock Certificates, etc., on Exercise.
As soon as practicable after the exercise of this Warrant in full or in part, the Company at its own expense (including the payment
by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder
(upon payment by such Holder of any applicable transfer taxes) may direct, a certificate or certificates for the number of fully
paid and non-assessable shares of Warrant Shares or Other Securities to which such Holder shall be entitled upon such exercise,
plus, in lieu of any fractional share to which such Holder would otherwise be entitled, cash equal to such fraction multiplied
by the then-current Market Price of one full share, together with any other stock or other securities and property (including cash,
where applicable) to which such Holder is entitled upon such exercise pursuant to Section 4 or otherwise.


 


4.Adjustment for Dividends in Other Stock, Property,
etc.; Reclassification, etc. In case at any time or from time to time after the Original Issue Date, the holders of Warrant
Shares (or, if applicable, Other Securities) shall have received, or (on or after the record date fixed for the determination of
stockholders eligible to receive) shall have become entitled to receive, without payment therefor


 


(a)other or additional
stock or other securities or property (other than cash) by way of dividend, or


 


(b)any cash paid or payable
(including, without limitation, by way of dividend), or


 


(c)other or additional
stock or other securities or property (including cash) by way of spin-off, split-up, reclassification, recapitalization, combination
of shares or similar corporate rearrangement,


 


then, and in each such case the Holder of this Warrant, upon
the exercise hereof as provided in Section 2, shall be entitled to receive the amount of stock and other securities and property
(including cash in the cases referred to in subdivisions (b) and (c) of this Section 4) which such Holder would hold on the date
of such exercise if on the Original Issue Date such Holder had been the Holder of record of the number of shares of Warrant Shares
called for on the face of this Warrant and had thereafter, during the period from the Original Issue Date to and including the
date of such exercise, retained such shares and all such other or additional stock and other securities and property (including
cash in the cases referred to in subdivisions (b) and (c) of this Section 4) receivable by such Holder as aforesaid during such
period, giving effect to all adjustments called for during such period by Section 5 hereof. If the number of shares of Warrant
Shares outstanding at any time after the date hereof is decreased by a combination or reverse stock split of the outstanding shares
of Common Stock, the Purchase Price per share shall be increased, and the number of shares of Warrant Shares purchasable under
this Warrant shall be decreased in proportion to such decrease in outstanding shares of Warrant Shares.

5.Reorganization, Consolidation, Merger, etc.
In case the Company after the Original Issue Date shall (a) effect a reorganization, (b) consolidate with or merge into any other
entity or (c) transfer all or substantially all of its properties or assets to any other entity under any plan or arrangement contemplating
the dissolution of the Company, then, in each such case, the Holder of this Warrant, upon the exercise hereof as provided in Section
3 at any time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution,
as the case may be, shall be entitled to receive (and the Company shall be entitled to deliver), in lieu of the Underlying Securities
issuable upon such exercise prior to such consummation or such effective date, the stock and other securities and property (including
cash) to which such Holder would have been entitled upon such consummation or in connection with such dissolution, as the case
may be, if such Holder had so exercised this Warrant immediately prior thereto, all subject to further adjustment thereafter as
provided in this Section 5; provided that if the sole consideration to which such Holder would have been entitled upon such consummation
or in connection with such dissolution, as the case may be, if such Holder had so exercised this Warrant immediately prior thereto,
is cash, the Warrant shall be terminated upon such consummation or dissolution. The Company shall not effect any such reorganization,
consolidation, merger or sale, unless prior to or simultaneously with the consummation thereof, the successor corporation resulting
from such consolidation or merger or the corporation purchasing such assets or the appropriate corporation or entity shall assume,
by written instrument, the obligation to deliver to each Holder the shares of stock, cash, other securities or assets to which,
in accordance with the foregoing provisions, each Holder may be entitled to and all other obligations of the Company under this
Warrant. In any such case, if necessary, the provisions set forth in this Section 5 with respect to the rights thereafter of the
Holders shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to any Other Securities or assets
thereafter deliverable on the exercise of the Warrants.


 


6.Further Assurances. The Company will take all
such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable

the Warrants, the Company will issue a certificate setting forth such adjustment or readjustment and the basis therefor.


 


8.Notices of Record Date, etc. In the event of


 


(a)any taking by the Company
of a record of its stockholders for the purpose of determining the stockholders thereof who are entitled to receive any dividend
or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or for the purpose of determining stockholders who are entitled to vote
in connection with any proposed capital reorganization of the Company, any reclassification or recapitalization of the capital
stock of the Company or any transfer of all or substantially all the assets of the Company to or consolidation or merger of the
Company with or into any other person, or
