         ; provided that in the event that a participant is terminated without
Cause (as defined below) or resigns for Good Reason (as defined below) within

the fiscal year of termination, prorated to the date of termination.  The
following definitions shall apply:

                 "Cause" means (a) a participant's willful violation of any
                 reasonable rule or direct order of the Board or the Company's

                 to do so, the participant fails to make reasonable efforts to
                 correct within a reasonable time, or (b) conviction of a
                 crime, or entry of a plea of nolo contendere with regard to a

                 premises or at a Company sponsored event, or (d) the
                 participant's material violation of any provision of this
                 Agreement, which, after written notice to do so, the
                 participant fails to make reasonable efforts to correct within
                 a reasonable time.  "Cause" shall not include any matter other
                 than these specified in (a) through (d) above, and without

                 injunctions, repairs, replacements, refunds, recalls or
                 seizures, if the participant acted in good faith and in a
                 manner which the participant reasonably believed to be in or

                 "Good Reason" means any of the following:  (a) breach
                 by the Company or any successor company of any of the
                 provisions of any employment agreement between the participant
                 and the Company not corrected within ninety (90) days after
                 written notice to the Company thereof, (b) reduction of a
                 participant's base salary, management bonus percentage or

                 contributions may be raised to the extent of any cost
                 increases imposed by third parties) or any action by the
                 Company which would adversely affect the participant's 
   2

                 participation or reduce the participant's benefits
                 under any of such plans, (d) material reduction in the
                 participant's job responsibilities, (iv) material reduction of

                 A "Change of Control" shall be deemed to have occurred
                 at any of the following times:

                          A.  Upon the acquisition (other than from the
                          Company) by any person, entity or "group," within the
                          meaning of Section 13(d)(3) or 14(d)(2) of the
                          Securities Exchange Act of 1934 (the "Exchange Act")
                          (excluding, for this purpose, the Company or its
                          affiliates, or any employee benefit plan of the
                          Company or its affiliates which acquires beneficial
                          ownership of voting securities of the Company) of
                          beneficial ownership (within the meaning of Rule
                          13d-3 promulgated under the Exchange Act) of 50% or
                          more of either the then outstanding shares of common
                          stock of the Company or the Combined Voting Power of
                          the Company's then outstanding voting securities.
                          "Combined Voting Power" means the combined voting
                          power of the Company's then outstanding voting
                          securities generally entitled to vote in the election
                          of directors.

                          B.  At the time individuals who, as of [date],
                          constitute the Board (as of [date], the "Incumbent
                          Board") cease for any reason to constitute at least a
                          majority of the Board, provided that any person
                          becoming a director subsequent to [date] whose
                          election, or nomination for election by the Company's
                          shareholders, was approved by a vote of at least a
                          majority of the directors then comprising the
                          Incumbent Board (other than an election or nomination
                          of an individual whose initial assumption of office
                          is in connection with an actual or threatened
                          election contest relating to the election of the
                          directors of the Company, as such terms are used in
                          Rule 14a-11 of Regulation 14A promulgated under the
                          Exchange Act) shall be, for purposes of this
                          subparagraph B, considered as though such person were
                          a member of the Incumbent Board; or

                          C.  Upon the approval by the shareholders of the
                          Company of a reorganization, merger, consolidation
                          (in each case, with respect to which persons who were
                          the shareholders of the Company immediately prior to
                          such reorganization, merger or consolidation do not,
                          immediately thereafter, own more than 50% of the
                          Combined Voting Power of the reorganized, merged or
                          consolidated company's then outstanding voting
                          securities) or a liquidation or dissolution of the
                          Company or of the sale of all or substantially all of
                          the assets of the Company; or

                          D.  The occurrence of any other event which the
                          Incumbent Board in its sole discretion determines
                          constitutes a Change of Control.

The following paragraph will be substituted in lieu of Section e)2. on page 6
of each plan:

         Profit for bonus determination will be inclusive of any changes in
reserves, but will exclude any capital gains or losses, other unusual gains or
losses such as proceeds of fire or casualty insurance, and extraordinary items.
In cases of uncertainty, the decision of the CEO will be final.  In the event
of a Change of Control, the Compensation Committee shall adjust profit for
bonus determination purposes hereunder to remove distortions in the Company's
profits and distortions in the method of measuring such profits, and
distortions in the methods used to determine and measure the realization of the
performance targets hereunder for bonus calculation purposes, that have
occurred as a result of the Change of Control.  In addition, the Compensation
Committee shall have the authority, in its sole and absolute discretion, to
adjust the performance targets hereunder for bonus calculation purposes to
remove distortions in the realization of such targets and distortions in the
method of measuring such realization and such targets, caused by actions taken
or expenses incurred by the Company in connection with a proposal for a
transaction described in subparagraphs A or C of the definition of Change of
Control set forth in subsection e)1. above, or any other extraordinary
transaction, whether or not consummated.  No changes in reserves shall be taken
into account for purposes of bonus calculations hereunder with respect to the
fiscal year in which a Change of Control occurs and the immediately following
fiscal year.
