shall be adjusted as hereinafter provided unless otherwise specifically provided
in a written agreement between the Employee and the Company relating to such
Options:

                  (a) If the shares of common stock shall be subdivided or
combined into a greater or smaller number of shares or if the Company shall
issue any shares of its common stock as a stock dividend on its outstanding
common stock, the number of shares of common stock deliverable upon the exercise
of Options shall be appropriately increased or decreased proportionately, and
appropriate adjustments shall be made in the purchase price per share to reflect
such subdivision, combination or stock dividend.

                  (b) If the Company is to be consolidated with or acquired by
another entity pursuant to an Acquisition, the board of directors of any entity
assuming the obligations of the Company hereunder (the "Successor Board") shall
either (i) make appropriate provision for the continuation of such Options by
substituting on an equitable basis for the shares then subject to such Options
the consideration payable with respect to the outstanding shares of common stock
in connection with the Acquisition; or (ii) terminate all Options in exchange
for a cash payment equal to the excess of the fair market value of the shares
subject to such Options over the exercise price thereof.

                  (c) In the event of a recapitalization or reorganization of
the Company (other than a transaction described in Section 6(b) above) pursuant
to which securities of the Company or of another corporation are issued with
respect to the outstanding shares of common stock, the Employee upon exercising
Options shall be entitled to receive for the purchase price paid upon such
exercise the securities he would have received if he had exercised his Options
prior to such recapitalization or reorganization.

                  (d) Except as expressly provided herein, no issuance by the
Company of shares of common stock of any class or securities convertible into
shares of common stock of any class shall affect, and no adjustment by reason
thereof shall be made with respect to, the number or price of shares subject to
Options. No adjustments shall be made for dividends or other distributions paid
in cash or in property other than securities of the Company.

                  (e) No fractional shares shall be issued and the Employee
shall receive from the Company cash in lieu of such fractional shares.

                                       4

<PAGE>

            (f) The Board or the Successor Board shall determine the specific
adjustments to be made under this Section 6, and its determination shall be
conclusive. If the Employee receives securities or cash in connection with a
corporate transaction described in Section 6(a), (b) or (c) above as a result of
owning such common stock, such securities or cash shall be subject to all of the
conditions and restrictions applicable to the common stock with respect to which
such securities or cash were issued, unless otherwise determined by the Board or
the Successor Board.

         7. Necessity to Become Holder of Record. Neither the Employee nor
            ------------------------------------
his/her estate, as provided in Section 4(c), shall have any rights as a
stockholder with respect to any shares covered by the Options until such person
shall have become the holder of record of such shares. No adjustment shall be
made for cash dividends or cash distributions, ordinary or extraordinary, in
respect of such shares for which the record date is prior to the date on which
he/she shall become the holder of record thereof.

         8. Reservation of Right to Terminate Relationship. Nothing contained in
            ----------------------------------------------

therefor, shall have the results provided for in Section 4 of this Agreement.

condition of the exercising of the Options granted hereunder, to give written

distribution of same, and that any subsequent resale of any such shares either
shall be made pursuant to a registration statement under the Securities Act and
applicable state law which has become effective and is current with regard to
the shares being sold, or shall be pursuant to an exemption from registration
under the Securities Act and applicable state law.

            The Options are subject to the requirement that, if at any time the
Board shall determine, in its discretion, that the listing, registration, or
qualification of the shares of common stock subject to the Options upon any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body, is necessary as a condition of,or
in connection with the issue or purchase of shares under the Options, the
Options may not be exercised in whole or in part unless such listing,
registration, qualification, consent or approval shall have been effected.

         10.Duties of Company.  The Company shall at all times during the term
            -----------------
