(a) For the quarters and  six-month  periods  ended March 28, 1998 and March 29,
1997,  the assumed  conversion of convertible  debentures,  giving effect to the
incremental  shares and the adjustment to reduce  interest  expense,  results in
anti-dilution  and has therefore  been excluded  from the  computation.  For the
quarter and six-month period ended March 28, 1998, the assumed exercise of stock
options,  giving effect to the incremental shares,  results in anti-dilution and
has therefore been excluded from the computation.
