      is the first operating loss our Company has reported since
      1991.  Business conditions were exceptionally difficult during
      the first quarter, but improved as the quarter progressed.  We
      do not know if the improvement will persist, but we are hopeful that it
      will.

      million on net sales of $190.4 million which compares with prior year
      earnings of $25.1 million on net sales of $383.9 million.  The
      decline in operating income was primarily due to lower unit shipments
      across most product lines and higher per unit conversion costs due to
      lower production volume.

      operating earnings of $25.6 million on net sales of $326.2 million for the
