                                                December 31, 1997

The Oversight Committee of
The Board of Directors
TriMas Corporation
315 East Eisenhower Parkway
Ann Arbor, MI  48108

Gentlemen:

               You have requested that BT Wolfensohn compare the premiums paid
in 22 specified transactions (the "Selected Premium Transactions") based on
the target's closing price on the date 52 weeks prior to the public
announcement of the transaction. The results of our comparison are set forth
on the attached worksheet.

               We understand that you have requested this premium comparison
in connection with the settlement of five purported class actions against
TriMas Corporation (the "Company"), MascoTech, Inc. ("Parent"), and the
Company's directors.  The premium comparison is not related to the opinion of
BT Wolfensohn dated December 10, 1997 that, as of such date and based upon and
subject to certain matters stated in such opinion, the consideration to be
paid in the transactions contemplated by the Agreement and Plan of Merger (the
"Merger Agreement"), dated December 10, 1997, among the Company, Parent and
MascoTech Acquisition, Inc., is fair to the holders of shares of the Company
(other than Parent, its Chief Executive Officer and Masco Corporation) from a
financial point of view, and the premium comparison does not amend, update or
supplement that opinion in any way.

               The attached comparison is based on publicly available
information.  BT Wolfensohn assumed and relied upon the accuracy and
completeness of such information, and neither assumed responsibility for
independent verification of, nor independently verified, any of such
information.  No company, business or transaction used in the attached
comparison is identical to the Company or the transactions contemplated by the
Merger Agreement.
