 NONCOMPETITION AND NONSOLICITATION AGREEMENT 

This NONCOMPETITION AND NONSOLICITATION AGREEMENT (this “Agreement”), dated as of
[                    ], 2015 (the “Effective Date”), is between TriMas Corporation, a Delaware corporation (“TriMas
Corporation”), and Horizon Global Corporation, a Delaware corporation (“Horizon Global Corporation”). 
 RECITALS

 A. Pursuant to the Separation and Distribution Agreement (the “Separation Agreement”) dated as of
[                    ], 2015, TriMas has agreed to distribute to its stockholders all of the outstanding shares of common stock of Horizon Global
Corporation owned by TriMas Corporation (the “Distribution”). 
 B. Before the Distribution, TriMas Corporation operated the Horizon
Business (as defined in the Separation Agreement) together with its other businesses as part of an integrated company for over thirty years. In December 2014, TriMas Corporation’s Board of Directors decided to separate the Horizon Business (as
defined in the Separation Agreement) from the TriMas Business into two separate publicly traded companies, so that each can focus on its own distinct growth strategy within its respective core market. 

C. Following the Distribution, TriMas will continue to conduct the TriMas Business (as defined in the Separation Agreement) and Horizon will continue to
conduct the Horizon Business (as defined in the Separation Agreement). 
 D. In connection with the Distribution, TriMas has transferred certain assets to
Horizon, which may, because of the nature of the assets, contain proprietary information and/or trade secrets still owned by TriMas. 
 E. Horizon’s
employees were formerly employees of TriMas and, because of the synergies and interactions between the two aspects of TriMas’s business before the Distribution, maintain in their minds and memories proprietary information and trade secrets
owned by TriMas. 
 F. Employees remaining with TriMas, because of the synergies and interactions between the two aspects of TriMas’s business before
the Distribution, maintain in their minds and memories proprietary information and trade secrets now owned by Horizon. 
 G. In connection with the
Distribution and in furtherance of the aims of the Distribution, to permit TriMas and Horizon each to tailor their respective business strategies to best address market opportunities in their respective industries and to permit the shareholders of
TriMas and Horizon to enjoy the anticipated benefits of the separation of TriMas into two separate entities and maintain each Party’s value and goodwill, it is necessary for each Party to temporarily limit its activities in the other
Party’s business as set forth herein. 







 In consideration of the foregoing and the mutual covenants and agreements contained in this
Agreement, and intending to be legally bound hereby, the Parties agree as follows:

have the meaning assigned to it herein. 
 ARTICLE VI

whole or in part, by operation of law or otherwise, by either Party without the prior written consent of the other Party, and any such assignment or delegation without such prior written consent will be null and void. If either Party to this
Agreement (or any of its successors or permitted assigns) (a) consolidates with or merges into any other Person and will not be the continuing or surviving corporation or entity of such consolidation or merger or (b) transfers all or
substantially all of its property and/or assets to any Person, then, and in each such case, the Party (or its successors or permitted assigns, as applicable) will ensure that such Person assumes all of the obligations of such Party (or its

6.11 Severability. Whenever possible, each provision or portion of any provision of this Agreement will be interpreted in such manner
as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision or portion of any provision had never been contained in this Agreement. 
 6.12 Modifications. If any
Governmental Authority determines that this Agreement, or any part hereof, is unenforceable, it is the intention of the Parties that such Governmental Authority have the power to modify this Agreement to the extent necessary to render it fully

Agreement or any interim drafts of this Agreement; and (l) a reference to any Person includes such Person’s successors and permitted assigns.

which when executed will be deemed to be an original but all of which taken together will constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or portable document format (PDF)
