disabled",  "disabled"  and  "disability"  shall mean  continuous  disability as
defined in, and for the period  necessary to qualify for, the benefits under any
disability income insurance  policies paid for by the Corporation on the life of
the Employee.

If no disability  insurance is in effect on the life of the Employee,  the terms
"totally   disabled",   "disabled",   and  "disability"  shall  mean  continuous
disability  which prevents the Employee from performing his normal duties in the
Corporation pursuant to this Agreement as shall be determined by two physicians,
one designated by the Corporation and the other  designated by the Employee.  If
these two  physicians  can not agree on whether the employee is disabled  within
the  meaning of this  Section,  they  shall  appoint a third  physician  and the
opinion of the majority shall be final, binding and conclusive.  The cost of all
examining  physicians  shall  be at  cost  to  the  Corporation  and  not to the
Employee.

of this  Agreement,  60% of his salary shall  continue for the remaining term of
this Agreement or for the period of time for which he remains totally  disabled,
whichever is shorter.

If the Corporation pays premiums on a disability  income insurance policy on the
life of the  Employee,  then any  proceeds  paid to the  Employee  by  reason of
disability under such disability insurance policy shall be offset against salary
continuation payments due from the Corporation.

Section  4.2  Illness.  In  addition,  if the  Employee is unable to perform the
services  required under this Agreement by reason of illness or physical  injury
not  amounting  to  disability  as defined  in this  Article,  the  compensation
otherwise  payable to the Employee  under this  Agreement  shall be continued in
full.
