     WHEREAS, the Board of Directors of the Company has authorized the grant of
the Option to the Optionee;

     NOW, THEREFORE, in consideration of the premises, mutual covenants herein
set forth and other good and valuable consideration, subject to the terms and
conditions herein, the Company and the Optionee hereby agree as follows:

     1.   Grant of Option. Subject to the terms and conditions herein, the
          ---------------
Company hereby grants to the Optionee an option (the "Option") to purchase
twenty-five thousand (25,000) shares (the "Option Shares") of its Common Stock
at an exercise price (the "Exercise Price") of $4.00 per share, as may be
adjusted from time to time as provided in this Agreement.

     2.   Exercise of the Option.
          ----------------------

          2.01.  Subject to adjustments as provided in Section 5 herein, the
Option shall be cumulatively exercisable: immediately as of the date hereof.

          2.02.  The Option shall expire on June 8, 2003 (the "Expiration Date")
subject to earlier termination as provided herein.

     3.   Rights of Holder. The Optionee shall not have any rights to dividends
          ----------------
or any other rights of a stockholder with respect to any Option Shares until
such Shares shall have been issued to him (as evidenced by the appropriate entry
on the transfer books of the Company) upon purchase of such Shares upon exercise
of the Option.





     4.   Non-Transferability of Option. This Option shall not be transferable
          -----------------------------
other than by will or by the laws of descent and distribution, and may be
exercised during the Optionee's lifetime only by him.

     5.   Adjustments.
          ------------

          5.01   Adjustments by the Company. In the event of a stock dividend,
                 --------------------------
stock split-up, share combination, exchange of shares, recapitalization, merger,
consolidation, acquisition or disposition of property or shares, reorganization,
liquidation or other similar changes or transactions, by the Company during the
term of the Option, the Board of Directors of the Company shall make such
adjustment of the number and class of shares then covered by the Option, or of
the Exercise Price, or both, whose determination shall be conclusive. To the
extent practicable, the Company shall give the Optionee prior notice of any such
event, provided that the failure by the Company to give such notice shall not
subject the Company to any liability herein.

          5.02   Adjustments Due to Merger, Consolidation, Reorganization, Asset
                 ---------------------------------------------------------------
Sale, Liquidation, etc. (a) If the Company shall be the surviving corporation in
- ----------------------
any reorganization, merger, consolidation, etc. of the Company with one or more
other corporations, any then outstanding Option shall pertain to and apply to
the securities to which a holder of the number of shares of Common Stock subject
to such Option would have been entitled immediately following such
reorganization, merger, consolidation, etc. with a corresponding proportionate
adjustment of the Exercise Price as to which such Option may be exercised so
that the aggregate Exercise Price as to which such Option may be exercised shall
be the same as the aggregate Exercise Price as to which such Option may be
exercised for the shares remaining subject to the Option immediately prior to
such reorganization, merger, consolidation, etc.

          (b)  In the event of a merger or consolidation in which the Company is
not the surviving corporation, or sale of all or substantially all of the assets
of the Company in which outstanding shares of Common Stock are exchanged for
securities, cash or other property of any other corporation or business entity
or in the event of a liquidation of the Company (collectively, a "Corporate
Transaction"), the Board of Directors of the Company, or the board of directors
of any corporation assuming the obligations of the Company, may, in its
discretion, take any one or more of the following actions, as to outstanding
Options: (i) provide that such Options shall be assumed or equivalent Options
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), (ii) upon written notice to the Optionee, provide that all
unexercised Options will terminate immediately prior to the consummation of such





transaction unless exercised by the Optionee within a specified period following
the date of such notice, or (iii) in the event of a Corporate Transaction under
the terms of which holders of the Common Stock of the Company will receive upon
consummation thereof a cash payment for each share surrendered in the Corporate
Transaction (the "Transaction Price"), make or provide for a cash payment to the
Optionee equal to the difference between (A) the Transaction Price times the
number of shares of Common Stock subject to such outstanding Options (to the
extent then exercisable at prices not in excess of the Transaction Price) and
(B) the aggregate Exercise Price of all such outstanding Options in exchange for
the termination of such Options.

     6.   Reservation of Shares. The Company shall at all times during the term
          ---------------------
of the Option reserve and keep available such number of shares of Common Stock
or such other class of stock then subject to the Option as shall be sufficient
to satisfy the requirements of this Agreement. The Company shall list such
shares of Common Stock on the national securities exchange or automated
quotation system on which the Company's Common Stock is then listed.

     7.   Exercise Procedure.
          ------------------

          7.01   Procedure. (a) The Optionee may exercise the Option, at any
                 ---------
time or from time to time as provided herein, by delivering to the Company a
written notice duly signed by the Optionee stating the number of Option Shares
that the Optionee has elected to purchase and accompanied by payment in an
amount equal to the full purchase price for the Option Shares to be purchased
(the "Purchased Shares"). The notice may be in form of the "Exercise of Option
to Purchase Shares" attached hereto. The payment may either be in cash or by
check.

          (b)  Following receipt by the Company of such notice of exercise and
full payment, the Company shall issue, as soon as practicable, a stock
certificate for the Purchased Shares in the name as designated by the Optionee
and deliver the certificate to the Optionee.

          7.02   Compliance. The Company, however, shall not be required to
                 ----------
issue or deliver the stock certificate pursuant to Section 7.01(b) hereof until
it has complied with all requirements of the Securities Act of 1933, as amended
(the "Securities Act"), the Securities Exchange Act of 1934, as amended, any
securities exchange or automated quotation system on which the Company's Common
Stock may then be listed, and all applicable state laws in connection with the
issuance of the Option Shares or their listing on said securities exchange or





system, including receiving representations by the Optionee as reasonably
required to ensure compliance with the foregoing laws.

          7.03   Legend. If the Purchased Shares are not then covered by a
                 ------
registration statement in accordance with Section 8 hereof, each certificate for
the Purchased Shares shall bear the following legend:

          "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED. SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED,
          PLEDGED OR HYPOTHECATED UNLESS THE REGISTRATION PROVISIONS OF SAID ACT
          HAVE BEEN COMPLIED WITH OR UNLESS THE COMPANY HAS RECEIVED AN OPINION
          OF ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED."

     8.   Registration Statement. The Optionee shall have a one-time "Piggyback
          ----------------------
Registration" right during the period of this Option, whereby if the Company
proposes to prepare and file with the Securities and Exchange Commission (the
"Commission") a Registration Statement (the "Registration Statement") on Form
S-2 or S-3 or any successor form under the Securities Act, assuming continued
eligibility by the Company to use such Form, the Company shall notify the
Optionee and will offer to include in such Registration Statement all or any
portion of the shares underlying such option. The Company makes no
representations regarding its ability to have any registration statement be
declared effective. In the event the Company is advised by the staff of the
Commission, NASDAQ or any self-regulatory or state securities agency that the
inclusion of the Optionee's shares will prevent, preclude or materially delay
the effectiveness of a registration statement filed, the Company, in good faith,
may amend such registration statement to exclude the Optionee shares without
otherwise affecting Optionee's rights to any other registration statement
herein. The Company shall bear the costs of preparing and filing the
Registration Statement (other than any selling costs of the Optionee) and may
include in such Registration Statement other shares of its Common Stock issued
to other persons. Notwithstanding the provisions of this Section 8, the Company
shall not be obligated to file a registration statement hereunder if the
Purchased Shares may then be sold pursuant to Rule 144 under the Securities Act.
