On March 4, 2013, Quinpario delivered a letter to the Corporate Secretary of the Issuer, as updated on March 12, 2013, March 15, 2013 and March 21, 2013 (the “Special Meeting Request”), requesting a special meeting of shareholders (the “Special Meeting”) be called by the Issuer in accordance with Section 2.02 of the Restated Bylaws (the “Bylaws”) for the following purposes:

to remove, without cause, at the Special Meeting up to all of the directors serving on the Board at the time of the Special Meeting, which for the avoidance of doubt shall include all individual(s) that may be elected or appointed to the Board to fill any existing or newly created directorship or vacancy on the Board during the period beginning on the date prior to the Company’s receipt of the Special Meeting Request, up to and through the date of the Special Meeting (the “Removal Directors”); and

(ii)

to elect Walter Thomas Jagodinski, James Heffernan, Edgar G. Hotard, Jeffry N. Quinn and Dr. John Rutledge, to the Board to fill the resulting vacancies that would exist in the event that some or all of the Removal Directors are successfully removed.

On March 27, 2013, Quinpario and the Issuer reached an understanding in furtherance of engaging in meaningful settlement communications regarding the proposed Special Meeting and Quinpario’s suggestions for the Issuer to capitalize on growth opportunities and enhance shareholder value, including but not limited to, the two strategic alternatives previously proposed by Quinpario to maximize shareholder value, and to determine whether a mutually acceptable resolution may be achieved. In order to facilitate such discussions, counsel for Quinpario and the Issuer, on behalf of their respective clients, executed a letter confirming the parties’ agreement to defer any further action to publicly advance or oppose the calling of the Special Meeting as contemplated in the Special Meeting Request, engage in any solicitation of proxies with respect thereto, or, in the case of the Issuer, take any action to limit the rights of Quinpario to call and cause to be held such requested Special Meeting in accordance with the Bylaws (the “Deferral”). Either party may terminate the Deferral at any time and for any reason upon at least two business days’ advance written notice to the other party. Quinpario and the Issuer each continue to otherwise reserve all rights in connection with advancing or opposing the Special Meeting Request following the termination of the Deferral period.
