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.
