RECITALS

WHEREAS, the Company, FrontFour and Quinpario have engaged in various discussions and communications concerning the Company’s business, financial performance and strategic plans;

WHEREAS, FrontFour is deemed to beneficially own shares of common stock of the Company (the “Common Stock”) totaling, in the aggregate, two million nine hundred seventy-eight thousand five hundred (2,978,500) shares, or approximately three and four-tenths percent (3.4%), of the Common Stock issued and outstanding on the date hereof;

WHEREAS, Quinpario is deemed to beneficially own shares of Common Stock totaling, in the aggregate, seven hundred thirty thousand (730,000) shares, or approximately eight-tenths of one percent (0.8%), of the Common Stock issued and outstanding on the date hereof;

WHEREAS, the FrontFour Group submitted a nomination letter to the Company on January 23, 2013 (the “Nomination Letter”) nominating director candidates to be elected to the Company’s board of directors (the “Board”) at the 2013 annual meeting of shareholders of the Company (the “2013 Annual Meeting”); and

WHEREAS, the Company and the FrontFour Group have determined to come to an agreement with respect to the election of members of the Board, including those to be elected at the 2013 Annual Meeting, certain matters related to the 2013 Annual Meeting and certain other matters, as provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows:

(a) The Company agrees that the Board and all applicable committees of the Board shall take all necessary actions to nominate Jeffry N. Quinn (“Quinn”) and David A. Lorber (“Lorber,” and with Quinn, the “New Appointees”) for election to the Board at the 2013 Annual Meeting.

(b) The Company agrees to take all necessary actions to modify its existing slate of three (3) directors who have been nominated by the Company to be elected at the 2013 Annual Meeting, by removing Richard C. Brown (“Brown”) and Gregory E. Hyland (“Hyland”) as nominees and replacing them with Quinn and Lorber, which shall include without limitation promptly creating and mailing additional solicitation materials and proxy cards reflecting the modified slate. As a result Brown and Hyland will not stand for re-election at the 2013 Annual Meeting and the Company’s slate of nominees for election at the 2013 Annual Meeting shall consist of Quinn, Lorber and Ronald P. Vargo. At the 2013 Annual Meeting, a director shall resign from the class of directors to serve through the 2014 annual meeting of shareholders of the Company and the Board shall immediately appoint Hyland to fill the resulting vacancy. During the Standstill Period (as defined below), the number of directors constituting the Board will be fixed at ten, provided, however, that this restriction shall not apply in the event that a shareholder delivers to the Company a request for the call of a special meeting of shareholders. The Company may reschedule the 2013 Annual Meeting to be held and concluded on a date not later than May 24, 2013.

(c) Upon the execution of this Agreement, the FrontFour Group hereby irrevocably withdraws its Nomination Letter and the FrontFour Group hereby agrees not to (i) nominate any person for election at the 2013 Annual Meeting, (ii) submit any proposal for consideration at, or bring any other business before, the 2013 Annual Meeting, directly or indirectly, or (iii) initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2013 Annual Meeting, directly or indirectly, and shall not permit any of its Affiliates or Associates to do any of the items in this Section 1(c). The FrontFour Group shall not publicly or privately encourage or support any other shareholder to take any of the actions described in this Section 1(c).

(d) The Company agrees that it will recommend, support and solicit proxies for the election of Quinn and Lorber at the 2013 Annual Meeting in the same manner as for the Company’s other nominee standing for election to the Board at the 2013 Annual Meeting.

(e) At the 2013 Annual Meeting, the FrontFour Group agrees to appear in person or by proxy and vote all shares of Common Stock beneficially owned by it (i) in favor of the election of each of the Company’s nominees for election to the Board (ratably with respect to all nominees), (ii) in favor of the Company’s “say-on-pay” proposal, (iii) for the shareholder proposal submitted by Kenneth Steiner, (iv) in favor of the 2013 Omnibus Incentive Plan, and (v) in favor of the proposal to amend the Company’s Code of Regulations to opt out of the Ohio Control Share Acquisition Act.

(f) The FrontFour Group agrees that it will cause each of its Affiliates and Associates to comply with the terms of this Agreement. As used in this Agreement, the terms “Affiliate” and “Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, or the rules or regulations promulgated thereunder (the “Exchange Act”) and shall include all persons or entities that at any time during the term of this Agreement become Affiliates or Associates of any person or entity referred to in this Agreement.

(g) The Company agrees that promptly following the conclusion of the 2013 Annual Meeting, but in any event no later than five business days thereafter, the Board will take all action necessary to create a committee of the Board to evaluate strategies to enhance shareholder value, including optimizing the Company’s capital structure, reviewing strategic proposals, reviewing its mix of businesses and improving operating performance (the “Strategy Committee”). The Strategy Committee will be comprised of five members consisting of the two New Appointees and three other directors designated by the Company. The Strategy Committee will function in accordance with the terms hereof until disbanded on the earlier of (i) the mutual agreement of the Parties or (ii) Board action any time after the expiration of the Standstill Period.

(h) The Company agrees that promptly following the conclusion of the 2013 Annual Meeting, but in any event no later than five business days thereafter, the Board will take all action necessary to appoint one New Appointee to the Governance & Nomination Committee of the Board and one New Appointee to the Compensation Committee of the Board, in each case as designated by the FrontFour Group in its sole discretion. The Company also agrees to promptly appoint one New Appointee, as designated by the FrontFour Group in its sole discretion, to any other committee of the Board (other than the Audit Committee) in existence on or after the date hereof, except as already contemplated under Section 1(g) hereof. The Company agrees that the Board will not cause any New Appointee to be removed from any committee of the Board to which such New Appointee was appointed pursuant to the terms hereof, provided, however, that this restriction shall not apply in the event that the FrontFour Group beneficially owns in the aggregate less than 1.5% of the Company’s then outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments).

(i) If elected at the 2013 Annual Meeting, the New Appointees will receive the same benefits of directors’ and officers’ insurance and any indemnity and exculpation arrangements available generally to the other Board members and the same compensation for service as a director as the compensation received by the other Board members.

(j) The Company agrees that if a New Appointee or any Replacement Director (as defined below) is unable to serve as a director, resigns as a director or is removed as a director prior to the 2016 annual meeting of shareholders of the Company (the “2016 Annual Meeting”) , and at such time the FrontFour Group beneficially owns in the aggregate at least 1.5% of the Company’s then outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments), the Company and the FrontFour Group shall discuss in good faith the mutual recommendation to the Governance & Nomination Committee of the Board of the appointment of a substitute person to fill the resulting vacancy in the class of directors with terms expiring at the 2016 Annual Meeting, which person shall (i) qualify as “independent” pursuant to NYSE listing standards, and (ii) have relevant financial and business experience. The appointment of any such person to the Board will be subject to the approval of the Governance & Nomination Committee, in its sole discretion, after exercising its fiduciary duties in good faith (any such replacement nominee appointed in accordance with the terms of this Section 1(j) shall be referred to as a “Replacement Director”). Upon the acceptance of a Replacement Director nominee by the Governance & Nomination Committee, the Board will appoint such Replacement Director to the Board no later than five business days after the Governance & Nomination Committee recommendation of such Replacement Director. Any such Replacement Director who becomes a Board member under this Section 1(j) shall be deemed a “New Appointee” for all purposes under this Agreement.

(a) The FrontFour Group agrees that, from the date of this Agreement until the earlier of (i) the date that is fifteen business days prior to the deadline for the submission of shareholder nominations for the 2014 annual meeting of shareholders of the Company pursuant to the Company’s Code of Regulations or (ii) the date that is ninety days prior to the first anniversary of the 2013 Annual Meeting (the “Standstill Period”), neither it nor any of its Affiliates or Associates under its control or direction will, and it will cause each of its Affiliates and Associates under its control not to, directly or indirectly, in any manner:
