entirety and replaced by the following:

         If the Company shall effect a subdivision or consolidation of shares or
other capital readjustment, the payment of a stock dividend or other increase or
reduction of the number of shares of Common Stock outstanding, without receiving
compensation therefor in money, services or property, then (a) the number, class
and per share price of shares of stock subject to outstanding Options hereunder
shall be appropriately adjusted in such a manner as to entitle an optionee to
receive upon exercise of an Option, for the same aggregate cash consideration,
the same total number and class or classes of shares as he would have received
had he

                                       1

exercised his Option in full immediately prior to the event requiring the
adjustment; and (b) the number and class of shares then reserved for issuance
under this Plan and the number of shares to be subject to the grants to be
made pursuant to Section 4 shall be adjusted by substituting for the total
number and class of shares of stock then reserved or subject to grant the

by the owner of an equal number of outstanding shares of Common Stock as the
result of the event requiring the adjustment, disregarding any fractional
shares.

3. Except as expressly amended by this Amendment, the Plan shall continue in
full force and effect in accordance with its terms.

Company's Common Stock (the "Purchase Price") shall be the average of the two
(2) lowest Stock Prices during the six (6) Trading Days prior to but excluding a
Mandatory Purchase Date, an Additional Purchase Date or a Call Purchase Date, as
the case may be (the "Purchase Price Period"); provided, however, that any
trading price below the Floor Price during such six (6) Trading Days shall be
deemed to be equal to the Floor Price for purposes of determining the Purchase
Price. If the Company, at any time during a Purchase Price Period, subdivides
(by any stock split, stock dividend, recapitalization, reorganization,
reclassification or otherwise) its shares of Common Stock into a greater number
of shares, then, as of the beginning of the Purchase Price Period, the Stock
Price in effect prior to such subdivision shall be proportionately reduced. If
the Company, at any time during a Purchase Price Period, combines (by reverse
stock split, recapitaliztion, reorganziation, reclassification or otherwise) its
shares of Common Stock into a smaller number of shares, then as of the beginning
of the Purchase Price Period, the Stock Price in effect prior to such
combination shall be proportionately increased."

                                   ARTICLE II

counterparts, all of which shall be considered one and the same agreement, it
being understood that all parties need not sign the same counterpart.
