<FN>
(a)   For the quarters and  nine-month  periods ended June 28, 1997 and June 29,
      1996, the assumed conversion of convertible  debentures,  giving effect to
      the incremental  shares and the adjustment to reduce interest expense,  is
      anti-dilutive and has therefore been excluded from the computation.
