          (a) For the quarters and  six-month  periods  ended March 27, 1999 and
     March 28, 1998, 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,
     is anti-dilutive and has been therefore excluded from the computation.
