      representing 50% or more of the combined voting power of the Corporation's

      (i), (iii) or (iv) or (B) a director nominated by any Person (including
      the Corporation) 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) whose election by the Board or nomination for election by the
      Corporation'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, cease for any reason to

      arrangement, reorganization or similar transaction or series of
      transactions in which the Corporation is involved, other than such a
      transaction or series of transactions which would result in the

      own (either by remaining outstanding or by being converted into voting
      securities of the surviving entity) more than 50% of the combined voting
      power of the securities of the Corporation or such surviving entity (or
      the parent, if any) outstanding immediately after such transaction(s) in

      than a liquidation of the Corporation into a wholly owned subsidiary.

      As used in this Section 17(m), "Person" (including a "group"), has the

      thereto).

      (n) For purposes hereof, "Disability" shall mean the Participant's absence
from the full-time performance of the Participant's duties pursuant to a
reasonable determination made in accordance with the Corporation's disability
plan that the Participant is disabled as a result of incapacity due to physical

six months.

<PAGE>

      (o) For purposes hereof, "Recapitalization Event" shall mean
recapitalization, reorganization, stock dividend or other special corporate
restructuring which results in an extraordinary distribution to the stockholders
of cash and/or securities through the use of leveraging or otherwise but which
does not result in a Change of Control.

                                      VII.

In all other respects, the Plan shall remain in full force and effect.
