      NOW, THEREFORE, in consideration, of the foregoing and of the mutual
covenants and agreements set forth herein and for other good and valuable
consideration, the receipt and adequacy of which is hereby acknowledged, the
parties hereto agree as follows:

      1. Definition of "Change in Control". The current definition of the term

entirety and the following is substituted in lieu thereof.

      "Change in Control" shall mean the occurrence of any of the following
events:

                  (i) The acquisition by any individual, entity or group

         under the Securities Exchange Act of 1934, as amended) of 25% or more
         of either (A) the then outstanding shares of common stock of Employer
         (the "Outstanding Company Common Stock") or (B) the combined voting
         power of the then outstanding voting securities of Employer entitled
         to vote generally in the election of directors (the "Outstanding

         this subsection (1), the following acquisition shall not constitute a
         Change in Control: (w) any acquisition directly from Employer, (x) any
         acquisition by Employer, (y) any acquisition by any employee benefit
         plan (or related trust) sponsored or maintained by Employer or any

         the Board of Directors of Employer (the "Incumbent Board") cease for
         any reason to constitute at least a majority of the Board, provided,
         however, that any individual becoming a director subsequent to the
         date hereof whose election, or nomination for election by Employer's
         shareholders, was approved by a vote of at least a majority of the
         directors then comprising the Incumbent Board shall be considered as
         though such individual were a member of the Incumbent Board, but
         excluding, for this purpose, any such individual whose initial
         assumption of office occurs as a result of an actual or threatened
         election contest with respect to the election or removal

                           (A) all or substantially all of the individuals and
                  entities who were the beneficial owners, respectively, of the
                  Outstanding Company Common Stock and outstanding Company
                  Voting Securities immediately prior to such Business
                  Combination beneficially own, directly or indirectly, more
                  than 65% of, respectively, the then outstanding shares of
                  common stock and the combined voting power of the then
                  outstanding voting securities entitled to vote generally in
                  the election of directors, as the case may be of the
                  corporation resulting from such Business Combination
                  (including, without limitation, a corporation which as a
                  result of such transaction owns Employer or all or
                  substantially all of Employer's assets either directly of
                  through one or more subsidiaries) in substantially the same
                  proportions as their ownership, immediately prior to such
                  Business Combination of the Outstanding Company Common Stock

                  (or related trust) of Employer or such corporation resulting
                  from such Business Combination) beneficially owns, directly
                  or indirectly, 25% or more of, respectively, the then
                  outstanding shares of common stock of the corporation
                  resulting from such Business Combination or the combined
                  voting power of the then outstanding voting securities of
                  such corporation except to the extent that such ownership
                  existed prior to the Business Combination, and

                           (C) at least a majority of the members of the board
                  of directors of the corporation resulting from such Business
                  Combination were members of the Incumbent Board at that time
                  of the execution of the initial agreement, or of the action
                  of the Board, providing for such Business Combination,

         inability of Participant, as determined by the Board, to substantially
         perform his regular duties and responsibility due to a medically
         determinable physical or mental illness which has lasted (or can
         reasonably be expected to last) for a period of six consecutive months.

         Eligible Participant's highest annual bonus payable with respect to
         any calendar year preceding his termination of employment, including
