      WHEREAS, pursuant to Section 5.7 of the Agreement, the Company and the

which specifically states that it is amending the Agreement;

      WHEREAS, the Company deems it appropriate, and the Optionee agrees, to
modify the provisions of the Agreement relating to the vesting and the
exercisability of the Superperformance Option (as such term is defined in the
Agreement) in connection with certain specified corporate events;

      NOW, THEREFORE, the parties hereto agree as follows:

                                       I.

      Section 1.6 of the Agreement is amended by adding the following at the end
      thereof:

      "Notwithstanding the foregoing, on or after June 15, 2004, a Change of
      Control shall mean:

                  (a) any Person (other than a Person holding securities
      representing 10% or more of the combined voting power of the Company's
      outstanding securities as of May 22, 2001, the Company, any trustee or
      other fiduciary holding securities under an employee benefit plan of the
      Company, or any company owned, directly or indirectly, by the shareholders
      of the Company in substantially the same proportions as their ownership of
      stock of the Company), becomes the beneficial owner, directly or
      indirectly, of securities of the Company,



      representing 50% or more of the combined voting power of the Company's
      then-outstanding securities; or

                  (b) during any period of twenty-four consecutive months (not
      including any period prior to May 22, 2001), individuals, who at the
      beginning of such period constitute the Board (the "Incumbent Board"),
      cease for any reason to constitute at least a majority of the Board;
      provided, however, that the Incumbent Board shall be deemed to include any
      new director, whose election by the Board or nomination for election by
      the Company's shareholders was approved by a vote of at least
      three-fourths (3/4) of the directors then still in office who either were
      directors at the beginning of the period or whose election or nomination
      for election was previously so approved; provided further that the
      Incumbent Board shall be deemed to exclude (A) any director nominated by a
      Person who has entered into an agreement with the Company to effect a
      transaction described in Section 1.6(a), (c) or (d) and (B) any director
      nominated by any Person (including the Company) who publicly announces an
      intention to take or to consider taking actions (including, but not
      limited to, an actual or threatened proxy contest) which if consummated
      would constitute a Change in Control); or

                  (c) the consummation of any merger, consolidation, plan of
      arrangement, reorganization or similar transaction or series of
      transactions in which the Company is involved; provided, however, that a
      Change of Control shall not include any transaction or series of
      transactions as a result of which the shareholders of the Company
      immediately prior thereto continue to own, in substantially the same
      proportions as their ownership immediately prior to such transaction(s),
      more than 50% of the combined voting power of the securities of the
      Company or such surviving entity (or the parent, if any) outstanding
      immediately after such transaction(s) (either by remaining outstanding or
      by being converted into voting securities of the surviving entity); or

                  (d) the shareholders of the Company approve a plan of complete
      liquidation of the Company or the sale or disposition by the Company of
      all or substantially all of the Company's assets, other than a liquidation
      of the Company into a wholly owned subsidiary.

      As used in herein, "Person" (including a "group"), has the meaning as such
      term is used for purposes of Section 13(d) or 14(d) of the Securities
      Exchange Act of 1934, as amended (or any successor section thereto)."

                                       II.

      Section 3.4 of the Agreement is amended by adding the following at the end
      thereof:

            "(d) The Superperformance Option I and the Superperformance Option
      II shall vest and become non-forfeitable (but only to the extent such
      Superperformance Option I and Superperformance Option II have not
      otherwise terminated or become exercisable) upon a Change of Control
      occurring at any time on or after June 15, 2004. Notwithstanding the
      accelerated vesting described



      in the immediately preceding sentence, any Superperformance Option I or
      Superperformance Option II subject to such accelerated vesting shall only
      become exercisable upon the earlier of (i) 9 1/2 years from the date of
      grant, and (ii) a Termination of Employment without Cause or for Good
      Reason or by reason of death, Disability or Retirement."

                                      III.

      Except as provided herein, the Agreement shall remain in full force and
      effect.

      IN WITNESS WHEREOF, this Amendment has been executed and delivered by the
parties hereto.
