termination and for a period of one (1) year following the date of such

such period, Executive shall continue to be entitled to participate in the
Company's employee benefits plans or arrangements (as set forth in Section 4
above) on the same basis as if he were an employee.

once Executive becomes Executive Vice President.  In each of the foregoing
circumstances except (D), written notice shall be given to Executive specifying

application thereof to any circumstance shall, in any jurisdiction and to any
extent, be invalid or unenforceable, such terms or provision shall be

provisions to circumstances other than those as to which it is held invalid or

Agreement shall mean the corporation that actually employs you.

          (h) Counterparts.  This Agreement may be executed in counterparts,
              ------------
each of which shall be deemed an original, but all of this together will
constitute one and the same instrument.
