Notwithstanding the foregoing, the Board of Directors may, in its sole discretion, determine that an annual meeting of shareholders will not be held at any place, but may instead be held by means of communications equipment, subject to such guidelines and procedures as the Board of Directors may adopt from time to time. When an annual meeting is not held or Directors are not elected thereat, they may be elected at a special meeting called for that purpose. The Board of Directors may postpone, adjourn or otherwise modify the date and time of any previously scheduled annual meeting of shareholders.

2. Special Meetings. Special meetings of the shareholders may be called by the President, or an Executive or Senior VicePresident, or the Chairperson of the Board of Directors, or by the Executive Committee, or by a majority of the Board of Directors, acting with or without a meeting, or by persons who hold twenty-five percent of all the shares outstanding and entitled to vote thereat (subject to the procedural requirements set forth in paragraph 6(c) of this Article II), at such place or places within or outside of the State of Ohio as may be designated in the call therefor, and notice thereof. Notwithstanding the foregoing, the Board of Directors may, in its sole discretion, determine that a special meeting of shareholders will not be held at any place, but may instead be held by means of communications equipment. The Board of Directors may postpone, adjourn or otherwise modify the date and time of any previously scheduled special meeting of shareholders.

3. Notice of Meetings. Subject to paragraph 6(c)(iv) of this Article II, notice of meetings of shareholders shall be given by the Secretary, or in his or her absence by the Chairperson of the Board or President or a Vice-President, and such notice shall state the purpose or purposes for which the meeting is called, the time and place, if any, where it is to be held, and the means, if any, by which shareholders can be present and vote at the meeting through the use of communications equipment, and shall be given to each shareholder of record entitled to vote at such meeting or entitled to notice thereof, at least ten days prior to the meeting. Notice may be given by personal delivery, mail, overnight delivery service, or any other means of communication authorized by the shareholder to whom notice is given. If mailed or sent by overnight delivery service, the notice shall be sent to the shareholder at the shareholder’s address as it appears on the records of the Corporation. If sent by another means of communication authorized by the shareholder, the notice shall be sent to the address furnished by the shareholder for those transmissions. In the event of the transfer of shares after notice has been given and prior to the holding of the meeting, it shall not be necessary to serve notice upon the transferee. Notice of any meeting of shareholders may be waived by the assent of the shareholder entitled to notice, filed with or entered upon the records of the meeting, either before or after the holding thereof.

4. Quorum. The holders of a majority of the shares issued and outstanding, entitled to vote, present in person, by proxy, or by the use of communications equipment at any meeting of shareholders shall constitute a quorum for such meeting, unless a larger number is required by the laws of Ohio, in which case the number required by the laws of Ohio, present either in person or by proxy, shall constitute a quorum, but any less number may adjourn the meeting from time to time, until a quorum is obtained, and no further notice of such adjourned meeting need be given other than by announcement at the meeting at which such adjournment is taken.

5. Proxies. Each shareholder entitled to vote shall be entitled to one vote, either in person or by proxy, for each share of the Corporation standing in his or her name at the time of the closing of the books for such meeting. No proxy shall be valid after the expiration of 11 months from the date thereof, unless a longer time be specified therein. Any shareholder directly or indirectly soliciting proxies from other shareholders must use a proxy card color other than white, which shall be reserved for exclusive use by the Board.

6. Order of Business.

(a) Order of Business Generally. The Chairperson of the Board, the Lead Director or an officer of the Corporation designated from time to time by (i) the Chairperson of the Board or (ii) a majority of the total number of Directors that the Corporation would have if there were no vacancies on the Board of Directors (the “Whole Board”) will call meetings of shareholders to order, will act as presiding officer thereof and may adjourn the meeting from time to time. Unless otherwise determined by the Board of Directors prior to the meeting, the presiding officer of the meeting of shareholders will also in his or her sole discretion determine the order of business of the meeting and the rules of procedure therefor, and have the authority to regulate the conduct of any such meeting as he or she deems appropriate in his or her sole discretion, including, without limitation, by imposing restrictions on the persons (other than shareholders of the Corporation or their duly appointed proxy holders) that may attend the meeting, by ascertaining whether any shareholder or his or her proxy holder may be excluded from the meeting based upon a determination by the presiding officer that any such person has disrupted or is likely to disrupt the proceedings thereat, by determining the circumstances in which any person may make a statement or ask questions at the meeting, by ruling on all procedural questions that may arise during or in connection with the meeting, and by determining whether any nomination or business proposed to be brought before the meeting has been properly brought before the meeting.

(b) Business to be Conducted at an Annual Meeting.

At an annual meeting of shareholders, only such business will be transacted or considered as is properly brought before the annual meeting. To be properly brought before an annual meeting, business (other than the nomination of a person for election as a Director, which is governed by Article V) must be (A) specified in the notice of the annual meeting or any supplement thereto, (B) otherwise properly brought before the annual meeting by the presiding officer or by or at the direction of a majority of the Whole Board, or (C) otherwise properly requested to be brought before the annual meeting by a shareholder of the Corporation in accordance with this paragraph 6.

In no event will the adjournment or postponement of an annual meeting (or public disclosure of any such adjournment or postponement) commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above.

The information required to be included in a shareholder’s notice to the Secretary pursuant to paragraph 6(b)(iv) must be updated and supplemented, if necessary, so that the information provided or required to be provided will be true and correct on the record date of the annual meeting and as of the date that is ten business days prior to the annual meeting or any adjournment or postponement thereof; which update shall be delivered to the Secretary no later than five business days after the record date for the annual meeting and not later than eight business days prior to the date of the annual meeting.

At a special meeting of shareholders, only such business may be transacted or considered as is properly brought before the special meeting. To be properly brought before a special meeting, business must be (A) specified in the notice of the special meeting or any supplement thereto and in the case of a special meeting called by shareholders of the Corporation, specified in the written request for the call of the special meeting, or (B) otherwise properly brought before the special meeting by the presiding officer or by or at the direction of a majority of the Whole Board.

The information required to be included in a shareholder’s request for the call of a special meeting pursuant to this paragraph 6(c) must be updated and supplemented, if necessary, so that the information provided or required to be provided will be true and correct on the record date of the special meeting and as of the date that is ten business days prior to the special meeting or any adjournment or postponement thereof. Any such update and supplement must be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation, as promptly as practicable.

If such notice is not given within 15 days after the delivery or mailing of such request, the person or persons requesting the meeting may fix the time of the meeting and give, or cause to be given, notice in the manner provided in paragraph 3 of this Article II.

(d) Determination as to Whether Business is Properly Brought Before a Meeting. Unless otherwise determined by the Board of Directors prior to the meeting, the determination of whether any business sought to be brought before any annual or special meeting of shareholders is properly brought before such meeting in accordance with this paragraph 6 will be made by the presiding officer of such meeting. If the presiding officer determines that any business is not properly brought before such meeting, he or she will so declare to the meeting and any such business will not be transacted or considered. Unless otherwise required by law, if the shareholder (or a qualified representative of the shareholder) does not appear at the annual or special meeting to present the proposed business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation.

The election of Directors shall be by ballot and shall be held at the annual meeting of shareholders or at a special meeting called for that purpose. The minimum number of the Directors of the Corporation shall be five and the maximum number of the Directors of the Corporation shall be 15. Subject to such minimum and maximum, the number of Directors may be fixed or changed (a) at a meeting

of the shareholders called for the purpose of electing Directors at which a quorum is present, by the affirmative vote of the holders of record of shares entitling them to exercise not less than two-thirds of the voting power of the Corporation entitled to vote generally in the election of Directors and (b) by the Directors, by the vote of a majority of their number, who may also fill any Director’s office that is created by an increase in the number of Directors. Each Director shall be elected for a term expiring at the next annual meeting of shareholders and until the election of his or her successor.

2. Vacancy and Removal. All Directors, for whatever terms elected, shall hold office subject to applicable statutory provisions as to the creation of vacancies and removal; provided, however, that all Directors or any individual Director may be removed from office, without assigning any cause, only by the affirmative vote of the holders of at least two-thirds of the voting power of the outstanding shares of stock entitled to vote generally on the election of Directors.

Notwithstanding the foregoing, meetings of Directors need not be held at a place and may be held through any communications equipment if all persons participating can hear each other, and such participation in a meeting will constitute presence in person at the meeting. A majority of the Directors then in office shall be necessary to constitute a quorum for the transaction of business, and the act of a majority of Directors present at a meeting at which a quorum is present shall be the act of the Board of Directors.

The Corporation may require any Nominating Person to furnish such other information as may be reasonably required by the Corporation or one of its representatives, acting in good faith, to determine the Nominating Person’s compliance with these Regulations or the accuracy and completeness of any notice or solicitation given or made on behalf of such Nominating Person or any proposed nominee to furnish such other information as may be reasonably required by the Corporation or one of its representatives, acting in good faith, to determine the qualifications and eligibility of such proposed nominee to serve as a Director of the Corporation.

(d) The information required to be included in a shareholder’s notice to the Secretary pursuant to paragraph 1(c) of this Article V must be updated and supplemented, if necessary, so that the information provided or required to be provided will be true and correct on the record date of the annual or special meeting and as of the date that is ten business days prior to the annual or special meeting or any adjournment or postponement thereof. Any such update and supplement must be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation, as promptly as practicable.

(e) For purposes of this Article V, “Nominating Person” means (i) the shareholder providing the notice of the nomination proposed made to be at an annual or special meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of nomination proposed to be made at the annual or special meeting is given, and (iii) any Affiliate or Associate (each within the meaning of Rule 12b-2 under the Exchange Act) of such shareholder or beneficial owner.

(f) If (i) any Nominating Person provides notice pursuant to Rule 14a-19(a)(1) under the Exchange Act and (ii) such Nominating Person subsequently either (A) notifies the Corporation that such Nominating Person no longer intends to, or is part of a group that no longer intends to, solicit proxies in support of Director nominees other than the nominees of the Board of Directors or a duly authorized committee thereof in accordance with Rule 14a-19 under the Exchange Act or (B) fails to comply with the requirements of Rules 14a-19(a)(2) and (3) under the Exchange Act (or with the interpretation of such requirements by the SEC with respect to special meetings, if applicable), then the Corporation shall disregard any proxies or votes solicited for the Nominating Person’s nominees, notwithstanding that proxies or votes in favor thereof may have been received by the Corporation. If any Nominating Person provides notice pursuant to Rule 14a-19(a)(1) under the Exchange Act, such Nominating Person shall deliver to the Secretary, no later than five business days prior to the applicable meeting, reasonable documentary evidence (as determined by the Corporation or one of its representatives in good faith) that the requirements of Rule 14a-19(a)(3) under the Exchange Act have been satisfied.

2. Substitution of Nominees. In the event that a person is validly designated as a nominee in accordance with paragraph 1 above, and shall thereafter become unable or unwilling to stand for election to the Board of Directors, the Board of Directors or the shareholder who proposed such nominee, as the case may be, may designate a substitute nominee upon delivery, not fewer than five days prior to the date of the meeting for the election of such nominee of a written notice to the Secretary setting forth such information regarding such substitute nominee as would have been required to be delivered to the Secretary pursuant to paragraph 1 above had such substitute nominee been initially proposed as a nominee. Such notice shall include a signed consent to serve as a Director of the Corporation, if elected, of each such substitute nominee.

3. Compliance with Procedures. Unless otherwise determined by the Board of Directors prior to the annual or special meeting, the determination of whether any nomination for the election of Directors is properly made in accordance with this Article V will be made by the presiding officer of such annual or special meeting. If the presiding officer determines that any nomination is not properly made, he or she will so declare to the meeting and the defective nomination will be disregarded, notwithstanding that proxies or votes in favor thereof may have been received by the Corporation. Unless otherwise required by law, if the shareholder (or a qualified representative of the shareholder) does not appear at the annual or special meeting to present a nomination, such

nomination shall not be made, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this paragraph 3, to be considered a qualified representative of the shareholder, a person must be a duly authorized officer, manager or partner of such shareholder or must be authorized to act for such shareholder as proxy at the annual or special meeting and such person must produce written evidence of such authority at the annual or special meeting. Notwithstanding the foregoing, a shareholder must also provide notice as required by, and otherwise comply with, all of the applicable requirements of the Exchange Act, including Rule 14a-19 thereunder, and the laws of the State of Ohio with respect to the matters set forth in this Article V. Nothing herein shall be deemed to affect any rights of shareholders to request inclusion of nominations in the Corporation’s proxy materials pursuant to applicable rules and regulations promulgated under the Exchange Act.
