Item 1.01 Entry Into Material Agreements.

On December 16, 2009, TriMas Corporation (the “Company”) and its wholly owned subsidiary, TriMas Company, LLC (the “Borrower”), entered into an Amended and Restated Credit Agreement (the “Amendment”). The Amendment was entered into by and among the Company, the Borrower, the consenting lenders party thereto, JP Morgan Chase Bank, N.A., serving as Administrative Agent and Collateral Agent, and Comerica Bank, serving as Syndication Agent.

Pursuant to the Amendment, certain revolving credit lenders agreed to extend the maturity of their revolving credit commitments from August 2, 2011 to December 15, 2013. After giving effect to reductions in revolving commitments of certain extending revolving lenders, the Borrower now has $70.0 million of extended maturity revolving credit commitments and $78.0 million of total revolving credit commitments.  Borrowing costs under the Amendment for the extended maturity tranche of revolving credit commitments will be LIBOR plus 4.00%, without an applicable “LIBOR floor.” Pursuant to the Amendment, the commitment fee payable with respect to the undrawn extended maturity revolving credit commitment is increased to 0.75%. The maturity date and interest margins with respect to the $8.0 million of revolving credit commitments held by lenders that did not consent to extend remain unchanged.

The Amendment also provides for: (a) the extension of the maturity of $226.3 million of the Company’s $252.2 million in term loans from August 2, 2013 to December 15, 2015 (the “Extended Term Loans”); (b) borrowing costs on the Extended Term Loans at LIBOR plus 4.00%, with a “LIBOR floor” of 2.00%; and (c) amendment for certain items including modified financial covenant levels to improve financial flexibility and the ability to refinance the Company’s existing subordinated notes with senior secured notes. The maturity date and interest margins with respect to those term loans held by lenders that did not consent to extend the maturity of their term loans will remain unchanged.

The description set forth above is qualified by the Amendment dated as of December 16, 2009 filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference to this item 1.01.
