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 the 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.
