                  insurance,  health and accident or disability  plan (including
                  the Plan), in which the Participant is participating at

                  the time of a Change  in  Control  of the  Employer  (or plans
                  providing  substantially similar benefits),  the taking of any

                  the basis of years of service with the Employer in  accordance
                  with the Employer's  normal  vacation  policy in effect on the
                  date hereof;

                  morale turpitude  (meaning a crime that  necessarily  includes
                  the commission of an act of gross depravity, dishonesty or bad
                  morals);  provided  that,  after the occurrence of a Potential
                  Change in  Control,  but prior to a Change in  Control,  Cause
                  shall  also  include  willful  and  gross  misconduct  that is
                  materially and demonstratively detrimental to the company.

         6.       Section 8.1 of the Plan is hereby amended to read as follows:

                  8.1 RIGHT TO  TERMINATE  OR AMEND.  The Board may, in its sole

                  amend the Plan at any time or from time to time. Any amendment
                  may provide  different  benefits  or amounts of benefits  from
                  those  herein  set  forth.  However,  no such  termination  or
                  amendment shall adversely  affect the benefits of Participants
                  which  have  accrued  prior to or as a result  of such  action
                  (including  termination  as described in Section 4.6(a) of the
                  Plan,  following  a Change in  Control),  the  benefits of any
                  Participant who has previously retired, or the benefits of any
                  Beneficiary of a Participant who has previously died.

         7.       Section 9.6 of the Plan is hereby amended as follows:

                  This Agreement shall be governed by and construed and enforced
                  in accordance with the laws of the State of Delaware.

         Except as otherwise  provided  above,  the  provisions  of the Plan, as
amended herein, shall continue in full force and effect.
