Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On and effective as of December 4, 2009, the Compensation Committee of the Board of Directors of TriMas Corporation (the “Corporation”) approved changes to the Corporation’s previously adopted Severance / Change of Control Policy (“Severance Policy”), which policy provides severance benefits to certain executive officers of the Corporation. The revised Severance Policy eliminates the Corporation’s obligation to pay any excise tax, to the extent incurred by an executive officer upon the payment of a severance benefit under the Severance Policy.  The revised Severance Policy also contains changes intended to comply with Section 162(m) of the Internal Revenue Code which changes are required to be in place by December 31, 2009.

The description of the Severance Policy above is qualified by the form attached hereto and filed herewith as Exhibit 10.1.

On December 4, 2009, the Compensation Committee, effective as of January 1, 2010, eliminated the Corporation’s current program of payment for certain perquisites for certain of its senior executives, including its executive officers and, implemented a Flexible Cash Allowance Policy (“Allowance Policy”) which provides such executives a cash allowance in place of any other Corporation provided perquisites. The Allowance Policy provides that the Compensation Committee may cancel or modify it at any time.

The description of the Allowance Policy above is qualified by the form attached hereto and filed herewith as Exhibit 10.2.
