disclose to anyone any advice, recommendation or work product of
any of LabOne's attorneys without having first received a writing
from LabOne authorizing any such disclosure, unless Employee gives
LabOne prompt written notice in order to permit LabOne to seek
injunctive relief to protect its interests in the event of any
attempt by a third party to require any such disclosure by Employee
and such disclosure by Employee is subsequently required by a final
order of a court of competent jurisdiction.  
     7.   Employee hereby represents and warrants that he has to
his best knowledge and belief disclosed to LabOne all technology,
inventions, discoveries, improvements, processes, formulae (secret
or otherwise), ideas, know-how, methods, compositions, research
projects, computer software programs and developments (collectively
"Developments"), whether or not such Developments are patentable or
copyrightable, which Employee by himself or in conjunction with
other persons has conceived, made, developed or acquired during his
employment by LabOne.  Employee hereby assigns, transfers and
conveys all of his right, title and interest in and to any and all
such Developments to LabOne, which Developments shall become and
remain the sole and exclusive property of LabOne.  All files of
Employee pertaining to any business of LabOne shall be and are the
property of LabOne and Employee represents that he has delivered to
LabOne all of such files.
     8.   This Agreement shall not alter any right Employee has as
a terminated employee under LabOne's Long-Term Incentive Plan,
Profit Sharing 401(K) Plan, Employees' Money Purchase Pension Plan
and Medical Benefits Plan.
     9.   Except as otherwise provided herein, the Employment
Agreement is hereby terminated and is of no further force or
effect.
     10.  Employee hereby releases and discharges LabOne and its

action are presently known or unknown.  LabOne hereby releases and
discharges Employee from and against any and all demands, claims,
causes of actions, sums due, damages, costs and expenses (except
for those arising out of any breach by Employee of his obligations
under this Agreement), related to or arising out of the Employment
