Notes:
          (1) Metaldyne acquired TriMas in January 1998. Financial results for
the 21 days prior to Metaldyne's acquisition have not been included because the
results were determined on a different accounting basis.

         (2) For the period ended December 31, 2002, the year ended December
31, 2001, and for the nine months ended september 30, 2001 additional earnings
of $5.3 million, $9.6 million and $1.2 million respectively, would have been
required to make the ratio 1.0x.
