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, 2000, and year ended
                  December 31, 2001, additional earnings of $5.3 million and
                  $9.6 million, respectively, would have been required to make
                  the ratio 1.0x.
