          --------------

          2.3.1  Exercise in Full.  The holder of this Warrant may exercise it
                 ----------------

The surrendered Warrant shall be accompanied by payment,

               X = Y (A-B) / A

     Where:    X = the number of shares of Common Stock to be issued to the

               cover
<PAGE>

               page of this Warrant Agreement, as adjusted pursuant to the
               provisions of Section 6 of this Warrant Agreement).

               Y = the number of shares of Common Stock for which the Warrant is
               being exercised.

               A = the "Market Price" of one share of Common Stock (for purposes
               of this Section), shall be defined as the closing bid price of
               the Common Stock on the business day immediately prior to the

               reported by the National Association of Securities Dealers
               Automated Quotation System ("NASDAQ"), or if the Common Stock is
               not traded on NASDAQ, the Closing Bid Price in the over-the-
               counter market; provided, however, that if the Common Stock is
               listed on a stock exchange, the Market Price shall be the Closing
               Bid Price on such exchange; and, provided further, that if the
               Common Stock is not quoted or listed by any organization, the
               fair value of the Common Stock, as reasonably determined by the
               Board of Directors of the Company, whose determination shall be
               conclusive, shall be used).

               B = the Exercise Price of $____ per share as stipulated herein.

         2.3.2 Partial Exercise.  This Warrant may be exercised in part by
               ----------------
surrender of this Warrant in the manner and at the place provided in this
Section 2.3 for the amount obtained by multiplying (a) the number of shares of
Common Stock the holder of this Warrant chooses to purchase as shall be
designated by the holder in the subscription at the end hereof by (b) the
Exercise Price.  On any such partial exercise, subject to the provisions of
Section 2 hereof, the Company at its expense will forthwith issue and deliver to
or upon the order of the holder hereof a new Warrant or Warrants of like tenor,
in the name of the holder hereof or as such holder may request, calling in the
aggregate on the face or faces thereof for the number of shares of Common Stock
remaining subject to this Warrant after the exercise contemplated herein.

         2.3.3 Company Acknowledgment.  The Company will, at the time of the
               ----------------------
exercise, exchange or transfer of this Warrant, upon the request of the holder
hereof acknowledge in writing its continuing obligation to afford to such holder
or transferee any rights (including, without limitation, any right to
registration of the Shares as set forth in the "Warrant Purchase Agreement",
attached hereto and incorporated by reference herein) to which such holder or
transferee shall continue to be entitled after such exercise, exchange or
transfer in accordance with the provisions of this Warrant, provided that if the
holder of this Warrant shall fail to make any such request, such failure shall
not affect the continuing obligation of the Company to afford to such holder or
transferee any such rights.

         2.3.4 Delivery of Stock Certificates, Etc., on Exercise.  As soon as
               -------------------------------------------------
practicable after the exercise of this Warrant in full or in part, and in any
event within 10 days thereafter, the Company at its 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
<PAGE>

Shares to which such holder shall be entitled on such exercise, and any
fractional Share to which such holder would otherwise be entitled shall be
eliminated pursuant to Section 6.3.

          2.3.5  Nothing contained herein shall be construed to confer upon the
Holder any of the rights of a shareholder of the Company until after such
Warrant is exercised.


3.   Transfer.
     --------

     3.1  General Restrictions.  The restrictions on transferability of this
          --------------------
Warrant shall be pursuant to Sections 3 and 4 of the Warrant Purchase Agreement
attached hereto and the Warrant Purchase Agreement shall be incorporated by
reference herein.

     3.2  Restrictions Imposed by the Securities Act.  This Warrant and the
          ------------------------------------------
Securities underlying this Warrant shall not be transferred unless and until (i)
the Company has received the opinion of counsel for the Holder that such
securities may be transferred pursuant to an exemption from registration under
the Act, and applicable state law, the availability of which is established to
the reasonable satisfaction of the Company, or (ii) a registration statement
relating to such Securities has been filed by the Company and declared effective
by the Securities and Exchange Commission ("SEC") and compliance with applicable
state law.

4.   New Warrants to be Issued.
     -------------------------

     4.1  Partial Exercise or Transfer.  Subject to the restrictions in Section
          ----------------------------
3 hereof, this Warrant may be exercised or assigned in whole or in part.  In the
event of the exercise or assignment hereof in part only, upon surrender of this
Warrant for cancellation, together with the duly executed exercise or assignment
form and funds (or conversion equivalent) sufficient to pay any Exercise Price
and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Warrant of like tenor to this Warrant in the name of the
Holder evidencing the right of the Holder to purchase the aggregate number of
shares of Common Stock and Warrants purchasable hereunder as to which this
Warrant has not been exercised or assigned.

     4.2  Lost Certificate.  Upon receipt by the Company of evidence
          ----------------
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant
and of reasonably satisfactory indemnification, the Company shall execute and
deliver a new Warrant of like tenor and date. Any such new Warrant executed and
delivered as a result of such loss, theft, mutilation or destruction shall
constitute a substitute contractual obligation on the part of the Company.

5.   Registration Rights.
     -------------------

          The Holders of this Warrant have been granted certain registration
rights as set forth in the Warrant Purchase Agreement between the Holder and
Company of even date herewith, and such warrant Purchase Agreement shall be

exercise such
<PAGE>

registration rights prior to the Exercise Date as set forth in the Warrant
Purchase Agreement.

6.   Adjustments
     -----------

     6.1  Adjustments
          -----------

     If the Company shall pay a dividend in shares of its Common Shares,
subdivide (split) its outstanding shares of Common Stock, combine (reverse
split) its outstanding shares of Common Stock, issue by reclassification of its
shares of Common Stock any shares or other securities of the Company, or
distribute to holders of its Common Stock any securities of the Company or of
another entity, the number of shares of Common Stock or other securities the
Holder hereof is entitled to purchase pursuant to this Warrant immediately prior
thereto shall be adjusted so that the Holder shall be entitled to receive upon
exercise the number of shares of Common Stock or other securities which he or
she would have owned or would have been entitled to receive after the happening
of any of the events described above had this Warrant been exercised immediately
prior to the happening of such event, and the exercise price per share shall be
correspondingly adjusted; provided, however, that no adjustment in the number of
shares and/or the exercise price shall be required unless such adjustment, or
cumulative adjustments, would require an increase or decrease of at least one
percent (1%) in such number and/or price; and provided further, however, that
any adjustments which by reason of this Section 6 are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.

     An adjustment made pursuant to this Section 6 shall become effective
immediately after the record date in the case of the stock dividend or other
distribution and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification.

     The Holder of this Warrant shall be entitled to participate in any
subscription or other rights offering made to holders of the Company's Common
Stock to the extent he or she would have been entitled had this Warrant been
exercised in the full number of shares as to which this Warrant remains
unexercised immediately prior to the record date for such rights offering.  If
the Company is consolidated or merged with or into another corporation or if all
or substantially all of its assets are conveyed to another corporation this
Warrant shall thereafter be exercisable for the purchase of the kind and number
of shares of stock or other securities or property, if any, receivable upon such
consolidation, merger or conveyance by a holder of the number of shares of
Common Stock of the Company which could have been purchased on the exercise of
this Warrant immediately prior to such consolidation, merger or conveyance; and,
in any such case, appropriate adjustment (as reasonably determined by the Board
of Directors) shall be made in the application of the provisions herein set
forth with respect to the rights and interests thereafter of the Holder of this
Warrant to the end that the provisions set forth herein (including provisions
with respect to changes in and other adjustments of the number of shares of
Common Stock the Holder of this Warrant is entitled to purchase) shall
thereafter by applicable, as nearly as possible, in relation to any shares of
Common Stock or other securities or other property thereafter deliverable upon
the exercise of this Warrant.
<PAGE>

     6.2  Changes in Form of Warrant.  This form of Warrant need not be changed
          --------------------------
because of any change pursuant to this Section, and Warrants issued after such
change may state the same Exercise Price and the same number of shares of Common
Stock and Warrants as are stated in the Warrants initially issued pursuant to
this Agreement.  The acceptance by any Holder of the issuance of new Warrants
reflecting a required or permissive change shall not be deemed to waive any
rights to a prior adjustment or the computation thereof.

     6.3  Fractional Interests.  The Company shall not be required to issue
          --------------------
certificates representing fractions of shares of Common Stock upon the exercise
of this Warrant, but shall make a cash payment for any fractional shares based
on the market price of the Common Stock on the date of exercise, which shall be
the closing sale price on the principal exchange on which the Common Stock is
traded; or if not traded on any exchange, then the representative closing bid
price on the OTCBB.

     7.   Reservation and Listing.  The Company shall at all times reserve and
          -----------------------
keep available out of its authorized shares of Common Stock, solely for the
purpose of issuance upon exercise of this Warrant, such number of shares of
Common Stock or other securities, properties or rights as shall be issuable upon
the exercise thereof.  The Company covenants and agrees that, upon exercise of
the Warrants and payment of the Exercise Price therefor, all shares of Common
Stock and other securities issuable upon such exercise shall be duly and validly
issued, fully paid and non-assessable and not subject to preemptive rights of
any stockholder. As long as the Warrants shall be outstanding, the Company shall
use its best efforts to cause all shares of Common Stock issuable upon exercise
of the Warrants to be listed (subject to official notice of issuance) on all
securities exchanges (or, if applicable on Nasdaq) on which the Common Stock is
then listed and/or quoted.

8.   Certain Notice Requirements.
     ---------------------------

     8.1  Holder's Right to Receive Notice.  Nothing herein shall be construed
          --------------------------------
as conferring upon the Holder the right to vote or consent or to receive notice
as a stockholder for the election of directors or any other matter, or as having
any rights whatsoever as a stockholder of the Company.  If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the
Company shall give written notice of such event at least fifteen days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale.  Such notice
shall specify such record date or the date of the closing of the transfer books,
as the case may be.

     8.2  Events Requiring Notice.
          -----------------------

               A. The Company shall be required to give the notice described in
this Section 8 upon one or more of the following events: (i) if the Company

all the holders of its Common Stock any additional shares of capital stock of
the Company or securities convertible into or exchangeable for shares of capital
stock of the Company, or any option, right or warrant to subscribe therefor, or
(iii) a merger or reorganization in which the Company is not the surviving
party, or (iv) a dissolution, liquidation or winding up of the Company (other
than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

               B. Company shall give holder confirmed delivery, written notice
that this Warrant, or any subsequent Warrant(s) issued pursuant hereto, will
expire no less than forty-five (45) days nor more than ninety (90) days before
the Warrant actually expires, and failure to give such notice shall
automatically extend such warrant and all its terms for a period equal to the
period of failure to notify plus forty five days.

     8.3  Notice of Change in Exercise Price.  The Company shall, promptly after
          ----------------------------------
an event requiring a change in the Exercise Price pursuant to Section 6 hereof,
send notice to the Holders of such event and change ("Price Notice").  The Price
Notice shall describe the event causing the change and the method of calculating
same and shall be certified as being true and accurate by the Company's
President and Chief Financial Officer.

     8.4  Transmittal of Notices.  All notices, requests, consents and other
          ----------------------
communications under this Warrant shall be in writing and shall be deemed to
