accept the severance offer and agree to be bound by this Agreement.




2.  General
Release of Claims.I, for myself and
my heirs, executors, administrators, assigns, agents and beneficiaries, if any,
do hereby agree to execute and be bound by this General Release of
Claims.  I waive, release, and forever discharge Employer (as defined
below) of and from any and all Claims (as defined
below) arising from the beginning of time up to and including the date of this
