           (c)  In the event of a Termination of Employment under Subsection

     pursuant to Section 7 or any interest credited thereon.   All
     Awards, and any interest credited thereon, shall be paid from
     the  general funds of the Company to the extent not paid from
     the grantor trust. Under no circumstances shall a Participant
     or   other  person  have  any  interest  whatsoever  in   any
     particular property or assets of the Company as a  result  of
     this Plan or an Award made thereunder."

     Amendment,  suspension or termination of the Plan  shall  not
     alter  the amount or payment of an Award made prior  to  such
     amendment, suspension or termination.

           (b)  The Plan may not be amended during an Anticipatory
     Change  of Control, except that the Board may amend the  Plan
     during  such  a  period as it may deem reasonably  necessary,
     upon  advice  of  counsel, to further the  interest  of the
     Company and its shareholders regarding any legal requirements
     and, provided further, that any such amendment which reduces,
     or could reduce, the value of any

                                 - 4 -


     benefit of a Participant, as determined in the sole discretion
     of the Special Plan Administrator, shall provide substantially
     equivalent value in replacement thereof to the Participant.

           (c)   The Plan may not be amended or terminated  on  or
     after a Change of Control until all payments that may be  due
     pursuant to Subsection 6(c) of the Plan, as determined in the
     sole  discretion  of  the Special Plan Administrator  of  the
     Change of Control Trust, have been made."
