         (c) CHAIRMAN OF THE BOARD OF DIRECTORS. Subject to the provision of
         Section 16, for so long as this Plan is in effect and shares are

         (d) FAIR MARKET VALUE. For purposes of this Section 4, the "fair market
         value" of a share of Common Stock as of any particular date shall mean
         (i) if the Common Stock is listed or admitted to trading on any
         securities exchange or on The National Association of Securities
         Dealers (the "NASD") Automated Quotation System ("Nasdaq") Stock
         Market's National Market, the closing price on such day on the
         principal securities exchange or on The Nasdaq Stock Market's National
         Market on which the Common Stock is traded or quoted, or if such day is
         not a trading day for such securities exchange or The Nasdaq Stock
         Market's National Market, the closing price on the first preceding day
         that was a trading day, (ii) if the Common Stock is not then listed or
         admitted to trading on any securities exchange or on The Nasdaq Stock
         Market's National Market, the closing bid price on such day as reported
         by the NASD, or if no such price is reported by the NASD for such day,
         the closing bid price as reported by the NASD on the first preceding
         day for which such price is available, and (iii) if the Common Stock is
         not then listed or admitted to trading on any securities exchange or on
         The Nasdaq Stock Market's National Market and no such closing bid price
         is reported by the NASD, as determined by another reputable quotation
         source selected by the Committee in good faith.

2. The second paragraph of Section 12 of the Plan hereby is deleted in its
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
number and class or classes of shares of stock that would have been received
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.
