Item 4.           Description of Securities.

Not applicable.

Item 5.           Interests of Named Experts and Counsel.

Not applicable.

Item 6.           Indemnification of Directors and Officers.

The Company is a Delaware corporation.  Section 145 of the General Corporation Law of Delaware as the same exists or may hereafter be amended, inter alia, provides that a Delaware corporation may indemnify any person who was, or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.  The indemnity may include expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that the person’s conduct was unlawful.

A Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the corporation’s best interests, except that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be liable to the corporation.

Where a present or former director or officer has been successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify the person against the expenses (including attorney’s fees) actually and reasonably incurred by such person in connection therewith.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability

asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such whether or not the corporation would have the power to indemnify such person against such liability under Section 145.

Article 8 of the Company’s certificate of incorporation provides that each person who was or is made a party to (or is threatened to be made a party to) or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was one of the Company’s directors or officers shall be indemnified and held harmless by the Company to the fullest extent authorized by the General Corporation Law of Delaware against all expenses, liability and loss (including without limitation attorneys’ fees, judgments, fines and amounts paid in settlement) reasonably incurred by such person in connection therewith.  The rights conferred by Article 8 are contractual rights and include the right to be paid by the Company the expenses incurred in defending such action, suit or proceeding in advance of the final disposition thereof.

Article 7 of the Company’s certificate of incorporation provides that the Company’s directors will not be personally liable to the Company or its stockholders for monetary damages resulting from breaches of their fiduciary duty as directors except (a) for any breach of the duty of loyalty to the Company or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the General Corporation Law of Delaware, which makes directors liable for unlawful dividends or unlawful stock repurchases or redemptions or (d) for transactions from which a director derives improper personal benefit.

The Company’s directors and officers are covered by insurance policies indemnifying them against certain civil liabilities, including liabilities under the federal securities laws (other than liability under Section 16(b) of the Exchange Act), which might be incurred by them in such capacities.  The Company has entered into indemnity agreements with its directors and certain of its executive officers for the indemnification and advancement of expenses to these persons.  The Company believes that these provisions and agreements are necessary to attract and retain qualified directors and executive officers.  The Company also intends to enter into these agreements with its future directors and certain of its executive officers.  Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7.           Exemption from Registration Claimed.

Not applicable.

Item 8.           Exhibits.

 Page 4 of 10 Pages

Item 9.           Undertakings.

The undersigned registrant hereby undertakes:

(a)           (1)       To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)        To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii)       To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement;

(iii)      To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2)       That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)       To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)           That, for the purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)           Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

We have represented TriMas Corporation, a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form S-8 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”).  The Registration Statement relates to the registration of an additional 1,000,000 shares of the Company’s common stock, $0.01 par value per share (the “Common Shares”), to be issued pursuant to awards under the TriMas Corporation 2006 Long Term Equity Incentive Plan (the “Plan”).

Based upon our examination of the Registration Statement and such other documents and matters as we deem relevant, it is our opinion that the Common Shares to be offered by the Company under the Plan pursuant to the Registration Statement have been duly authorized by the Company and, when issued and sold by the Company in accordance with the Plan and the awards thereunder, will be legally issued, fully paid and nonassessable.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement.  In giving such consent, we do not admit hereby that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission thereunder.
