BOARD OF DIRECTORS

     SECTION I. Election, Number and Term of Office

     Directors shall be elected at the annual meeting of shareholders, or if not so elected, at a special meeting of shareholders called for that purpose. Except as otherwise provided in these Regulations, a Director shall hold office until the next succeeding annual meeting and until his successor shall be elected and qualified, or until his earlier resignation, death or removal from office.

     At any meeting of shareholders at which Directors are to be elected, only persons may be nominated as candidates with respect to whom proxies have been solicited from the holders of shares entitled to be voted at the meeting; provided that if any such candidate is unable, for any reason, to accept such nomination or to serve as a Director, the Directors then in office or the holders of two-thirds

of the shares entitled to be voted at the meeting may substitute another person as a nominee, or reduce the number of nominees to such extent as they shall deem advisable.

     Until changed in accordance with the provisions of statute, the Articles or the Regulations, the number of Directors of the Corporation shall be eleven. Without amendment of these Regulations, the number of Directors may be changed to not less than nine nor more than eighteen by the vote of the holders of two-thirds of the shares entitled to be voted at a meeting called to elect Directors. No reduction in the number of Directors shall have the effect of removing any Director prior to the expiration of his term of office.

     Until the 2013 annual meeting of shareholders, the Directors shall be divided into three classes, designated as Class I, Class II and Class III, each class consisting of not less than three Directors nor more than six Directors each. Each class shall consist, as nearly as may be possible, of one-third of the total number of Directors. Each class or Director of any class being elected at any election of Directors held prior to the 2013 annual meeting of shareholders shall be separately elected.

     At the 2010 annual meeting of shareholders, Directors elected for Class I shall hold office for a term of three years expiring at the 2013 annual meeting of shareholders and thereafter until their successors shall be elected and duly qualified. At the 2011 annual meeting of shareholders, Directors elected for Class II shall hold office for a term of two years expiring at the 2013 annual meeting of shareholders and thereafter until their successors shall be elected and duly qualified. At the 2012 annual meeting of shareholders, Directors elected for Class III shall hold office for a term of one year expiring at the 2013 annual meeting of shareholders and thereafter until their successors shall be elected and duly qualified. At each election of Directors after the 2012 annual meeting of shareholders, each Director shall be elected to hold office until the next annual meeting of shareholders and thereafter until his successor shall be elected and duly qualified.

     The number of Directors fixed as provided in this Section may be increased or decreased by the Directors and the number of Directors as so changed shall be the number of Directors until further changed in accordance with this Section, provided that the Directors shall not increase the number of Directors to more than eighteen or decrease the number of Directors to fewer than nine. If the number of Directors is changed prior to the 2013 annual meeting of shareholders, any increase or decrease shall be apportioned among the classes so as to maintain the number of Directors in each class as nearly equal as possible.

     SECTION 2. Vacancies

     Any vacancy or vacancies among the Directors may be filled by the Directors then in office. Until the 2013 annual meeting of shareholders, any Director elected to fill a vacancy may be elected for the term remaining for the Directors of any class, provided that each class shall continue to consist of not less than three Directors and the number of Directors in each class shall continue to be as nearly equal as possible. From and after the 2013 annual meeting of shareholders, any Director elected to fill a vacancy shall be elected until the next succeeding annual meeting of shareholders and thereafter until his successor shall be elected and duly qualified.

     SECTION 3. Removal

     A Director may be removed from office, as permitted by statute, by the Directors then in office or, upon the recommendation of two-thirds of the Directors then in office, by the vote of the holders of two-thirds of the shares entitled to be voted to elect Directors in place of those to be removed, except as otherwise provided by statute. For the purpose of determining “the Directors then in office”, the Director whose removal is proposed will not be deemed to be a Director, nor will such Director be entitled to vote thereon.

     SECTION 4. Meetings

     Meetings of the Directors may be called by the Chairman of the Board, the President, any Vice President, the Secretary, or by not less than one-third of the Directors then in office. Meetings of the Directors may be held at any place within or without the state of Ohio. Notice of the time and place of such meetings shall be served upon or telephoned to each Director at least twenty-four hours, or mailed, telegraphed or cabled to each Director at least forty-eight hours, before the time of the meeting. Such notice may be waived in writing by any Director, either before or after the meeting. Attendance at the meeting by a Director without protesting, prior to or at the commencement of the meeting, the lack of proper notice, shall constitute waiver of such notice by such Director.

     SECTION 5. Quorum

     A majority of the Directors then in office shall constitute a quorum for the transaction of business at any meeting. Except as otherwise provided by statute or by these Regulations, the act of a majority of the Directors present at any meeting at which a quorum is present shall be the act of the Directors. In the absence of a quorum, a majority of Directors present may adjourn any meeting from time to time without notice until a quorum is present.

     SECTION 6. Committees

     The Directors may from time to time create a committee or committees of Directors to act in the intervals between meetings of the Directors and may delegate to such committee or committees any of the authority of the Directors, except as limited by statute.

     In particular, the Directors may create from its membership and define the powers and duties of an Executive Committee of not less than three members. Except to the extent that its powers are limited by the Directors or by statute, the Executive Committee during the intervals between meetings of the Directors shall possess and may exercise under the control and direction of the Directors all of the powers of the Directors in the management and control of the business of the Corporation regardless of whether such powers are specifically conferred by these Regulations. All action taken by the Executive Committee shall be reported to the Directors at their first meeting thereafter.

     Unless otherwise provided by the Directors, a majority of the members of any committee appointed by the Directors pursuant to this Section shall constitute a quorum at any meeting thereof and the act of a majority of the members present at a meeting at which a quorum is present shall be the act of such committee. Action may be taken by any such committee without a meeting by a writing signed by all its members. Any such committee shall prescribe its own rules for calling and holding meetings and its method of procedure, subject to any rules prescribed by the Directors, and shall keep a written record of all action taken by it.

     SECTION 7. Compensation

     Directors and members of any committee of the Directors shall receive such compensation, which may be either a specified sum payable at intervals, and/or a fixed sum for attendance at each Directors or committee meeting or as otherwise determined by the Directors. No Director and no member of any committee of the Directors shall be disqualified from being counted in the determination of a quorum at any meeting of either the Directors or a committee by reason of the fact that matters affecting his own compensation as a Director, member of a committee, an officer or employee are to be determined. Nothing contained herein shall be construed to preclude any Director from serving the Corporation in any other capacity and receiving proper compensation for such service.

ARTICLE III

     SECTION 1. Officers
