1 Upon the change of control associated with the Berkshire  Transaction,  all of
the options  vested.  As part of the closing,  each option was  cancelled and in
consideration  of such  cancellation  the  Company  paid each  holder cash in an
amount  equal to the product of (A) the  excess,  if any, of $35.05 over the per
share  exercise  price and (B) the  number of shares  of  Company  Common  Stock
subject thereto.

2 As required by the  Securities  and  Exchange  Commission  ("SEC"),  potential
values stated are based on the prescribed  assumption that the Company's  Common
Stock will  appreciate  in value from the date of grant to the end of the option
term  (ten  years  from the date of grant)  at  annualized  rates of 5% and 10%,
respectively,  and  therefore  are not  intended  to  forecast  possible  future
appreciation,  if any, in the price of the Company's  Common Stock. The total of
all stock options  granted to employees,  including  executive  officers  during
fiscal 1998 was  approximately 1% of total shares  outstanding  during the year.
Accordingly,  the potential  value of such options for all  optionees  under the
prescribed  assumptions is approximately 1% of the potential realizable value of
all shareholders for the same period under the same assumptions.  (For the total
percentages  including  repricings,  see footnote 2 below.) As an alternative to
the assumed  potential  realizable  values stated above,  SEC rules would permit
stating  the  present  value of such  options  at the date of grant.  Methods of
computing   present  value  suggested  by  different   authorities  can  produce
significantly  different results.  Moreover,  since stock options granted by the
Company  are not  transferable,  there are no  objective  criteria  by which any
computation  of  present  value can be  verified.  Consequently,  the  Company's
management  does not believe there is a reliable method of computing the present
value  of  such  stock  options  and  that  all  assumptions  as  to  annualized
appreciation rates are inherently speculative.
