3.  Issuance in Connection with Agreement to Provide Guaranty; Number of Shares; Exercise of Warrant.





3.1Issuance in Connection with Agreement to Provide Guaranty.    Each of the Holder and the Company expressly acknowledge and
agree that this Warrant has been issued in connection with the execution and delivery by the Holder of that certain Agreement to Provide Guaranty of even date herewith by and between the Company and the Holder (Agreement). The number of
Shares that may be acquired pursuant to this Warrant shall be calculated on an annual basis (for each year the Guaranty remains outstanding) based upon One Hundred Ninety Thousand Dollars ($190,000) (the Base Calculation Amount) and the
Fair Market Value of the Companys Common Stock. For the purposes of this Warrant, Fair Market Value of Companys Common Stock shall be equal to the average of the last sale per share price of Common Stock on each of the ten
(10) trading days prior to date of calculation and adjustment of the of Shares to be included herein on the principal exchange of which the Common Stock may at the time be listed; or, if there shall have been no sales on such exchange on any such
trading day, the average of the closing bid and asked prices on such exchange on such trading day; or, if there is no such bid and asked price occurred; or, if the Common Stock shall not be so listed, the average of the closing sales prices as
reported by NASDAQ (including its bulletin board) at the end of each of the ten trading days prior to the date of exercise of this Warrant in the over-the counter market.





3.2  Calculation of Shares.    The aggregate number of Shares that the Holder of this Warrant shall have the right to purchase from
the Company (and the Company shall issue and sell to such Holder) shall be calculated on the date of this Warrant and each anniversary of this Warrant that Holders Guaranty under the Agreement remains in effect (the Allotment Date)
as follows: the number of Shares to which this Warrant applies (Annual Allotment) shall be the quotient of the Base Calculation Amount divided by the Fair Market Value per share on each Allotment Date. On each Allotment Date the Annual
Allotment shall be added to the number of Shares covered by this Warrant immediately prior to such Allotment Date.





3.3  Exercise.    This Warrant may be exercised in whole or in part in as many exercises as Holder may elect. The Exercise Price shall be payable by check for good and sufficient United States funds.





3.4  Cashless Exercise.    Subject to the other provisions of this
Agreement, in lieu of any cash payment required upon exercise of the Warrant, the Holder may elect to exercise this Warrant in full or in part by surrendering this Warrant in the manner specified in this Section 3 in exchange for the number of
shares of Common Stock equal to the product of (i) the number of shares of Common Stock as to which the Warrant is being exercised multiplied by (ii) a fraction, (y) the numerator of which is the Fair Market Value of a share of Common Stock on the
date of exercise less the Exercise Price, and (z) the denominator of which is the Fair Market Value of a share of Common Stock on such date of exercise.

3.5  Delivery.    The Warrant shall be exercisable by (i) delivering to the Company the form of notice of exercise attached hereto
as Exhibit A duly completed and signed by the Holder or by the duly appointed legal representative or duly authorized attorney thereof, and (ii) depositing with the Company the original of this Warrant, paying the aggregate Exercise Price for
the number of shares of Common Stock in respect of which the Warrant is being exercised. Upon each partial exercise of the Warrant, a new Warrant evidencing the balance of the shares of Common Stock issuable hereunder will be issued to the Holder,
as soon as reasonably practicable, on the same terms as the Warrant partially exercised. All payments due upon any exercise of this Warrant shall be made in cash or by check.





3.6  Time of Exercise.    This Warrant shall be deemed to have been exercised immediately prior to the close of business on the
date of its surrender for exercise and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date; provided,
however, that in the event that the transfer books of the Company are closed on the date of exercise, the Holder shall be deemed to have become a stockholder of record on the next succeeding day that the transfer books are open and until such date,
the Company shall be under no duty to cause to be delivered any certificate for such shares. As promptly as practicable on or after such date and in any event within ten (10) days thereafter, the Company at its expense shall issue and deliver to the
person or persons entitled to receive the same a certificate or certificates for the number of shares issuable upon such exercise. In the event that this Warrant is exercised in part, the Company at its expense will execute and deliver a new Warrant
of like tenor exercisable for the number of shares for which this Warrant may then be exercised.





4.  Payment of
Taxes and Expenses.    The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of this Warrant and the Warrant Stock,
unless any such tax or charge is imposed by law upon the Holder or upon the income or gain of Holder in connection with this Warrant, in which case such tax or charge shall be paid by the Holder. The Company shall not be required, however, to pay
any tax or other charge imposed in connection with any transfer involved in the issuance of any certificate for shares of Common Stock in any name other than that of the Holder, and in such case the Company shall not be required to issue or deliver
any stock certificate until such tax or other charge has been paid or it has been established to the satisfaction of the Company that no such tax or other charge is due.





5.  No Fractional Shares.    No fractional shares shall be issued upon the exercise of this Warrant. In lieu of any fractional share to which the
Holder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.





6.  Replacement of Warrant.    On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction,
on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, or surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor and amount.

7.  Adjustments.





(a)  Adjustment.    The number of shares of Common Stock for which this Warrant is exercisable and the Exercise Price at which such shares may be purchased shall be subject to adjustment from time to
time as set forth in this Section 7.





(b)  Stock Dividends, Subdivisions and
Combinations.    If at any time the Company shall:





(i)  pay or make a
dividend on Common Stock payable in additional shares of Common Stock;





(ii)  subdivide its
outstanding shares of Common Stock into a larger number of shares of Common Stock; or





(iii)  combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock;





then (A) the number of shares
of Common Stock for which this Warrant is exercisable immediately after the happening of such event shall be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock immediately prior
to the happening of such event would own or be entitled to receive after the happening of such event, and (B) the Exercise Price shall be adjusted to equal (1) the Exercise Price multiplied by the number of shares of Common Stock for which this
Warrant is exercisable immediately prior to the adjustment divided by (2) the number of shares for which this Warrant is exercisable immediately after such adjustment.





(c)  Dividends and Distributions.    If the Company shall distribute to all holders of its outstanding shares of Common Stock
evidence of indebtedness of the Company, cash (including cash dividends payable out of consolidated earnings or earned surplus) or assets or securities other than additional shares of Common Stock, including stock of a subsidiary but excluding
dividends or distributions referred to in Section 7(b) above (any such evidences of indebtedness, cash, assets or securities, the assets or securities), then, in each case, the number of shares of Common Stock issuable after such
record date to Holder upon the exercise of each Warrant shall be determined by multiplying the number of shares of Common Stock issuable upon the exercise of such Warrant immediately prior to such record date by a fraction, the numerator of which
shall be the fair market value per share of Common Stock immediately prior to the record date for such distribution and the denominator of which shall be the fair market value per share of Common Stock immediately prior to the record date for such
distribution less the then fair value (as determined in good faith by the Board) of the evidences of its indebtedness, cash or assets or other distributions so distributed attributable to one share of Common Stock. Such adjustment shall be made
whenever any such distribution is made, and shall become effective on the date of distribution retroactive to the record date for the determination of stockholders entitled to receive such distribution. Any adjustment required by this Section
7(c) shall be made whenever any such distribution is made, and shall become effective on the date of such distribution retroactive to the record date for the determination of stockholders entitled to receive such distribution.

(d)  Reorganization, Reclassification, Consolidation or Merger.    If the Company shall (i) effect any reorganization or
reclassification of its capital stock or (ii) consolidate or merge with or into, or transfer all or substantially all of its properties and assets to, any other person, in either case the Company shall give the holder at least thirty (30) days prior
written notice of such action. During such thirty (30) day period, the Holder shall have the right to exercise this Warrant in whole or in part in accordance with the terms hereof. In the event that the Holder does not exercise this Warrant or any
part hereof prior to the consummation of such transaction, then immediately upon the consummation of such transaction this Warrant and all rights hereunder shall immediately terminate without further notice to the Holder or further action on the
part of the Company.





(e)  All calculations under this Section 7 shall be made to the nearest
cent or to the nearest one-hundredth of a share, as the case may be.





8.  No Rights of
Stockholders.    Subject to this Warrant, the Holder shall not be entitled to vote, to receive dividends or subscription rights, or to be deemed the holder of Common Stock 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 Holder, as such, any of the rights of a stockholder of the Company, including without limitation any right to vote for
the election of directors or upon any matter submitted to stockholders, to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to
no par value, consolidation, merger, conveyance, or otherwise), to receive notices, or otherwise, until the Warrant shall have been exercised as provided herein.





9.  Transfer of Warrant.





9.1  Warrant Register.    The Company will maintain a register (the Warrant Register) containing the names and addresses of the Holder or Holders. Any Holder of this Warrant or any portion
thereof may change its address as shown on the Warrant Register by written notice to the Company requesting such change, and the Company shall promptly make such change. Until this Warrant is transferred on the Warrant Register of the Company, the
Company may treat the Holder as shown on the Warrant Register as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary.





9.2  Exchange of Warrant Upon a Transfer.    On surrender of this Warrant for exchange, properly endorsed on the Assignment
attached hereto and subject to the provisions of this Warrant and with the limitations on assignments and transfers as contained in this Section 9, the Company at its expense shall issue to or on the order of the Holder a new warrant or warrants of
like tenor, in the name of the Holder or as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for the number of shares issuable upon exercise hereof.





10.  Reservation and Authorization of Common Stock.





(a)  The Company shall at all times reserve and keep available for issuance upon the exercise of this Warrant the maximum number of its authorized but unissued shares of Common Stock as could then
potentially be required to permit the exercise in full of this and all

outstanding Warrants. All shares of Common Stock issuable upon exercise of any Warrant and payment therefor in accordance with the terms of such Warrant shall be duly and validly issued and fully paid and
nonassesable, and not subject to or privileged with any preemptive rights.





(b)  Before taking any
action which would cause an adjustment reducing the Exercise Price below the then par value, if any, of the shares of Common Stock issuable upon exercise of the Warrants, the Company shall take any corporate action which may be necessary in order
that the Company may validly and legally issue fully paid and nonassessable shares of such Common Stock at such adjusted Exercise Price.
