|    |        
|--- | -------
|X = | Y (A-B)
|    |

| |                                                                                                            
| | -----------------------------------------------------------------------------------------------------------
| | Where: X =
 The number of shares of Common Stock to be issued to the Holder pursuant to

For purposes
of this Warrant, the fair market value of one share of Common Stock as of a
particular date shall be determined as follows: (i) if traded on a securities
exchange or through the Nasdaq Stock Market or through an interdealer quotation
system such as the OTC Bulletin Board, the value shall be deemed to be the
average of the closing sale prices of the Common Stock on such exchange or
quotation system over the ten (10) day period ending three (3) days prior to
the net exercise election; (ii) if traded over-the-counter, the value shall be
deemed to be the average of the closing sale price over the ten (10) day period
ending three (3) days prior to the net exercise. If there is no reported sale
price for the Common Stock the fair market value of the Common Stock shall be
the value as determined in good faith by the Board of Directors of the
Corporation.

2.1
Delivery of Certificates. As soon as possible, and in any event within
fifteen (15) days, after each exercise of the purchase rights represented by
this Warrant, the Corporation, at its expense, shall deliver a certificate for

has been fully exercised or expired, a new Warrant representing the balance of
the shares of Common Stock subject to this Warrant.

Stock issuable upon any exercise of the purchase rights represented by this
Warrant shall be

treated for
all purposes as the holder of such shares of record as of the close of business
on the date of exercise.

2.3
Issue Taxes. The Corporation shall pay all issue and other taxes that
may be payable in respect of any issue or delivery to the Holder of shares of
Common Stock upon exercise of this Warrant.

3.
Stock Fully Paid; Reservation of Shares. The Corporation covenants and
agrees that all securities that it may issue upon the exercise of the rights
represented by this Warrant will, upon issuance, be fully paid and
nonassessable and free from all taxes, liens and charges. The Corporation
further covenants and agrees that, during the period within which the Holder
may exercise the rights represented by this Warrant, the Corporation shall at
all times have authorized and reserved for issuance enough shares of its Common
Stock or other securities for the full exercise of the rights represented by
this Warrant. The Corporation shall not, by an amendment to its Articles of
Incorporation or through reorganization, consolidation, merger, dissolution,
issue or sale of securities, sale of assets or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of
this Warrant.

4.
Adjustments. The Warrant Price and the number of shares of Common Stock that
the Corporation must issue upon exercise of this Warrant shall be subject to
adjustment in accordance with Sections 4.1 through 4.3.

4.1
Adjustment to Warrant Price for Combinations or Subdivisions of Common Stock.
If the Corporation at any time or from time to time after the date hereof (1)
declares or pays, without consideration, any dividend on the Common Stock
payable in Common Stock; (2) creates any right to acquire Common Stock for no
consideration; (3) subdivides the outstanding shares of Common Stock (by stock
split, reclassification or otherwise); or (4) combines or consolidates the
outstanding shares of Common Stock, by reclassification or otherwise, into a
lesser number of shares of Common Stock, the Corporation shall proportionately
increase or decrease the Warrant Price, as appropriate.

4.2
Adjustments for Reclassification and Reorganization. If the Common Stock
issuable upon exercise of this Warrant changes into shares of any other class
or classes of security or into any other property for any reason other than a
subdivision or combination of shares provided for in Section 4.1, including
without limitation any reorganization, reclassification, merger or
consolidation, the Corporation shall take all steps necessary to give the
Holder the right, by exercising this Warrant, to purchase the kind and amount
of securities or other property receivable upon any such change by the owner of
the number of shares of Common Stock subject to this Warrant immediately before
the change.

4.3
Spin Offs. If the Corporation spins off any subsidiary by distributing
to the Corporations shareholders as a dividend or otherwise any stock or other
securities of the subsidiary, the Corporation shall reserve until the
Expiration Date enough of such shares or other securities for delivery to the
Holders upon any exercise of the rights represented by this Warrant to the same
extent as if the Holders owned of record all Common Stock or other securities
subject to this Warrant on the record date for the distribution of the
subsidiarys shares or other

3

---



securities.

4.4
Certificates as to Adjustments. Upon each adjustment or readjustment
required by this Section 4, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with this Section, cause
independent public accountants selected by the Corporation to verify such
computation and prepare and furnish to the Holder a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based.

5.
Fractional Shares. The Corporation shall not issue any fractional shares
in connection with any exercise of this Warrant.

6.
Dissolution or Liquidation. If the Corporation dissolves, liquidates or
winds up its business before the exercise or expiration of this Warrant, the
Holder shall be entitled, upon exercising this Warrant, to receive in lieu of
the shares of Common Stock or any other securities receivable upon such
exercise, the same kind and amount of assets as would have been issued,
distributed or paid to it upon any such dissolution, liquidation or winding up
with respect to such shares of Common Stock or other securities, had the Holder
been the holder of record on the record date for the determination of those
entitled to receive any such liquidating distribution or, if no record is
taken, upon the date of such liquidating distribution. If any such dissolution,
liquidation or winding up results in a cash distribution or distribution of
property which the Corporations Board of Directors determines in good faith to
have a cash value in excess of the Warrant Price provided by this Warrant, then
the Holder may, at its option, exercise this Warrant without paying the
aggregate Warrant Price and, in such case, the Corporation shall, in making
settlement to Holder, deduct from the amount payable to Holder an amount equal
to such aggregate Warrant Price.

7.
Transfer and Exchange.

7.1
Transfer. Subject to Section 7.3, the Holder may transfer all or part of
this Warrant at any time on the books of the Corporation at its principal
office upon surrender of this Warrant, properly endorsed. Upon such surrender,
the Corporation shall issue and deliver to the transferee a new Warrant or
Warrants representing the Warrants so transferred. Upon any partial transfer,
the Corporation shall issue and deliver to the Holder a new Warrant or Warrants
with respect to the Warrants not so transferred.

7.2
Exchange. The Holder may exchange this Warrant at any time at the
principal office of the Corporation for Warrants in such denominations as the
Holder may designate in writing. No such exchanges will increase the total
number of shares of Common Stock or other securities that are subject to this
Warrant.

7.3
Securities Act of 1933. By accepting this Warrant, the Holder agrees
that this Warrant and the shares of the Common Stock issuable upon exercise of
this Warrant may not be offered or sold except in compliance with the 1933 Act,
and then only with the recipients agreement to comply with this Section 7 with
respect to any resale or other disposition of such securities. The Corporation
may make a notation on its records in order to implement such

4

---



restriction on
transferability.

8.
Loss or Mutilation. Upon the Corporations receipt of reasonably
satisfactory evidence of the ownership and the loss, theft, destruction or
mutilation of this Warrant and (in the case of loss, theft or destruction) of a
reasonably satisfactory indemnity or (in the case of mutilation) upon surrender
and cancellation of this Warrant, the Corporation shall execute and deliver a
new Warrant to the Holder.

9.
Successors. All the covenants and provisions of this Warrant shall bind
and inure to the benefit of the Holder and the Corporation and their respective
successors and assigns.
