Agreement"). For good and valuable consideration, the Parties hereby agree as

      2. Issuance of Stock Options.

      (a) Pursuant to the terms of the Advisory Services Agreement, the Company
hereby grants to the Holder, options (the "Options") exercisable into shares of
the Company's Stock, at a price and in the amounts set forth in Schedule A
attached hereto. The Options shall become exercisable upon achievement of the
milestones (the "Milestones") set forth in Schedule A attached hereto.

      (b) Status of Option(s). The Option(s) are non-qualified stock options.

      3. Right to Exercise. The Options issued herein shall vest and be
exercisable in whole or in part when the Milestones as set forth in Schedule A
are reached.

      (a) Option Exercise and Payment. The Options may be exercised by written
notice to the Company, in form and substance satisfactory to the Company, which
must state the election to exercise the Options, the number of shares of Stock
for which the Option is being exercised and such other representations and
agreements as to your investment intent with respect to such shares as may be
required pursuant to the provisions of this Agreement. The written notice must
be accompanied by full payment of the exercise price for the number of shares of

                                       -1-


      (b) Cashless Exercise. The holder shall also have the right to exercise
options by receiving in shares the difference between the option price and the
fair market value of the stock at the time of exercise.

      (c) In the event a change in control occurs, all options will become
immediately exercisable.

      Change in Control shall be deemed to have occurred if:

            (i) Any "person" (as such term is used in Sections 13(d) and 14(d)
            of the Exchange Act) is or becomes a "beneficial owner" (as defined
            in Rule 13d-3 under the Exchange Act), directly or indirectly, of
            securities of the Company representing more than 35% of the voting
            power of the then outstanding securities of the Company, and such
            person owns more aggregate voting power of the Company's then
            outstanding securities entitled to vote generally in the election of
            directors than any other person;

            (ii) The shareholders of the Company approve (or, if shareholder
            approval is not required, the Board approves) an agreement providing
            for (x) the merger of consolidation of the Company with another
            corporation where the shareholders of the Company, immediately prior
            to the merger or consolidation, will not beneficially own,
            immediately after the merger or consolidation, shares entitling such
            shareholders to 50% or more of all votes to which all shareholders
            of the surviving corporation would be entitled in the election of
            directors (without consideration of the rights of any class of stock
            to elect directors by a separate class vote), (y) the sale or other
            disposition of all or substantially all of the assets of the
            Company, or (z) a liquidation or dissolution of the Company; or

            (iii) directors are elected such that a majority of the members of
            the Board shall have been members of the Board for less than two
            years, unless the election or nomination for election of each new
            director who was not a director at the beginning of such two-year
            period was approved by a vote of at least two-thirds of the
            directors then still in office who were directors at the beginning
            of such period.

      (c) Effect of Failure to Exercise. Any failure by Holder to exercise any
Options, or any exercise for less than all shares purchasable under the Option,
shall not affect Holder's right to exercise the unexercised portion at a later
time.

      4. Piggyback Registration. In the event that the Company proposes to
register any of its Stock, under the Securities Act of 1933, as amended (the
"Securities Act"), whether or not for sale for its own account, in a manner that
would permit registration of registerable securities for sale for cash to the
public under the Securities Act, it shall afford the Holder piggyback
registration rights of its registerable shares pursuant to the Registration
Rights Agreement, attached hereto as Exhibit A.


                                       -2-


      5. Capital Adjustments. In the event that Stock is changed into or
exchanged for a different number or kind of shares of stock or other securities
of the Company, whether through merger, consolidation, reorganization,
recapitalization, stock dividend, stock split-up or other substitution of
securities of the Company, the Board shall make appropriate equitable
anti-dilution adjustments to the number and class of shares of stock available
for issuance under this Agreement and to the option price. Any reference to the
option price in this Agreement shall be a reference to the option price as so
adjusted.

      6. Form of Payment. The Option exercise price may be paid, in whole or in
part, (i) in cash, by check, or by cash equivalent, or (ii) by any other form of
payment permitted by the Company.

      7. Representations and Warranties. The Company represents and warrants

lien or encumbrance on any of the properties of the Company under any of the
foregoing.

other governmental investigation pending, or to the best of the Company's
knowledge, threatened against, or affecting the Company's business or its assets
before any court or governmental agency or other body, which would adversely
affect the financial condition of The Company, its assets, or the conduct of the
Company's business, or which may impede the transaction contemplated herein.
There are no outstanding and unpaid judgments, tax deficiencies, statements, or
notices of assessments or other demands for payment of taxes served on or filed
against the Company. The Company is not in default with respect to an order,
