Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those shareholders who have not consented in writing.

ARTICLE II

Directors

Section 1. Powers. Except where the Ohio Revised Code, as amended from time to time (the “Ohio Revised Code”), the Articles of Incorporation, or these Regulations require action to be authorized or taken by the shareholders, all of the authority of the Corporation shall be exercised by or under the direction of the Board of Directors.

Section 2. Number of Directors. Until changed in accordance with the provisions of this section, the number of directors of the Corporation, none of whom need be shareholders, shall be not less than one. The number of directors may be fixed or changed at any annual meeting or at any special meeting called for that purpose by the affirmative vote of the holders of shares entitling them to exercise a majority of the voting power of the Corporation on such proposal.

Section 3. Election of Directors. Directors shall be elected at the annual meeting of shareholders, but when the annual meeting is not held or directors are not elected thereat, they may be elected at a special meeting called and held for that purpose. Such election shall be by ballot whenever requested by any shareholder entitled to vote at such election; but, unless such request is made, the election may be conducted in any manner approved at such meeting. At each meeting of shareholders for the election of directors, the persons receiving the greatest number of votes shall be directors.

Section 4. Chairman of the Board. The Board of Directors may, in its discretion, elect from among its members a Chairman of the Board of Directors and such Chairman, if elected, shall preside at all meetings of the Board of Directors and shall have such other powers and duties as may be prescribed by the Board of Directors.

Section 5. Term of Office. Each director shall hold office until the next election of directors and until his successor is elected and qualified, or until his earlier resignation, removal from office or death.

Section 6. Removal. All the directors, or all the directors of a particular class, or any individual director may be removed from office, without assigning any cause, by the vote of the holders of a majority of the voting power entitling them to elect directors in place of those to be removed, provided that unless all the directors, or all the directors of a particular class, are removed, no individual director shall be removed in case the votes of a sufficient number of shares are cast against his removal which, if cumulatively voted at an election of all the directors, or all the directors of a particular class, as the case may be, would be sufficient to elect at least one director. In case of any such removal, a new director may be elected at the same meeting for the unexpired term of each director removed.

Section 7. Vacancies. Vacancies in the Board of Directors may be filled by a majority vote of the remaining directors until an election to fill such vacancies is had. Shareholders entitled to elect directors shall have the right to fill any vacancy in the Board (whether the same has been temporarily filled by the remaining directors or not) at any meeting of the shareholders called for that purpose, and any directors elected at any such meeting of shareholders shall serve until the next annual election of directors and until their successors are elected and qualified.

Section 8. Quorum and Transaction of Business. A majority of the whole number of directors shall constitute a quorum for the transaction of business, except that a majority of the directors in office shall constitute a quorum for filling a vacancy on the Board of Directors. Whenever less than a quorum is present at the time and place appointed for any meeting of the Board of Directors, a majority of those present may adjourn the meeting from time to time, until a quorum shall be present. The act of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors.

Section 9. Annual Meeting. Annual meetings of the Board of Directors shall be held at such times and places, within or without the State of Ohio, as the Board of Directors may determine.

Section 12. Notice of Annual or Special Meetings. Notice of the time and place of each annual or special meeting shall be given to each director by the secretary or by the person or persons calling such meeting. Such notice need not specify the purpose or purposes of the meeting and may be given in any manner or method and at such time so that the director receiving it may have reasonable opportunity to participate in the meeting. Such notice shall, in all events, be deemed to have been properly and duly given if mailed or sent electronically at least twenty-four (24) hours prior to the meeting and directed to the residence or email address of each director as shown upon the secretary’s records and, in the event of a meeting to be held through the use of communications equipment, such notice shall set forth the telephone number or other access information by which each director may join or participate in such meeting. The giving of notice shall be deemed to have been waived by any director who shall participate in such meeting and may be waived, in a writing, by any director either before or after such meeting.

Section 13. Compensation. The directors, as such, shall be entitled to receive such reasonable compensation for their services as may be fixed from time to time by resolution of the Board of Directors, and expenses of attendance, if any, may be allowed for attendance at each annual, regular or special meeting of the Board of Directors. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 15. Action Without Meeting. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if a consent in writing, setting forth the actions so taken, shall be signed by all members of the Board of Directors or such committee, as the case may be, and such written consent is filed with the minutes of proceedings of the Board of Directors or such committee.

Section 16. Committees. The Board of Directors may, by resolution adopted by a majority of directors, designate one or more directors to constitute one or more committees to serve at the pleasure, and exercise the authority, of the Board of Directors to the extent provided in the resolution establishing the committee and permitted by law.

ARTICLE V

Indemnification and Insurance

Section 1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she is or was a director or officer of the Corporation or that, being or having been such a director or officer of the Corporation, he or she is or was serving at the request of the Board of Directors or an officer of the Corporation as a director, officer, partner, employee or agent of another corporation or of a partnership, joint venture, trust, limited liability company or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whenever the basis of such proceeding is alleged action in an official capacity as such a director, officer, partner, employee, or agent, shall be indemnified and held harmless by the Corporation to the fullest extent permitted by Chapter 1701 of the Ohio Revised Code, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), or by other applicable law as then in effect, against all expense, liability and loss (including, without limitation, attorneys’ fees, costs of investigation, judgments, fines, excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974, rules or orders of the Securities and Exchange Commission or other federal or state acts, rules or regulations) actually incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Except as provided in Section 2 of this Article V with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized or ratified by the Board of Directors.

The right to indemnification conferred in this Section 1 shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending or prosecuting any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”). An advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee including, without limitation, service to an employee benefit plan) shall be made only

upon delivery to the Corporation of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it is proved by clear and convincing evidence in a court of competent jurisdiction that his or her omission or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the Corporation or undertaken with reckless disregard for the best interests of the Corporation. An advancement of expenses shall not be made if the Board of Directors makes a good faith determination that such payment would violate applicable law.

Section 2. Right of Indemnitee to Bring Suit. If a claim under Section 1 of this Article V is not paid in full by the Corporation within thirty (30) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall also be entitled to be paid the expense of prosecuting or defending such suit. The indemnitee shall be presumed to be entitled to indemnification under this Article V upon submission of a written claim (and, in an action brought to enforce a claim for an advancement of expenses, where the required undertaking has been tendered to the Corporation), and thereafter the Corporation shall have the burden of proof to overcome the presumption that the indemnitee is so entitled. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel or its shareholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its shareholders) that the indemnitee is not entitled to indemnification, shall be a defense to the suit or create a presumption that the indemnitee is not so entitled.

Section 3. Nonexclusivity and Survival Rights. The rights to indemnification and to the advancement of expenses conferred in this Article V shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provisions of the Articles of Incorporation, these Regulations, agreement, vote of shareholders or disinterested directors or otherwise.

Notwithstanding any amendment to or repeal of this Article V, or of any of the procedures established by the Board of Directors pursuant to Section 6 of this Article V, any indemnitee shall be entitled to indemnification and to advancement of expenses in accordance with the provisions hereof and thereof with respect to any acts or omissions of such indemnitee occurring prior to such amendment or repeal.

Without limiting the generality of the foregoing paragraph, the rights to indemnification and to the advancement of expenses conferred in this Article V shall, notwithstanding any amendment to or repeal of this Article V, inure to the benefit of any person who otherwise may be entitled to be indemnified pursuant to this Article V (or the estate or personal representative of such person) for a period of six years after the date such person’s service to or in behalf of the Corporation shall have terminated or for such longer period as may be required in the event of a lengthening in the applicable statute of limitations.

Section 4. Insurance, Contracts and Funding. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the

Corporation or another corporation, partnership, joint venture, trust, limited liability company or other enterprise against any expense, liability, or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under Chapter 1701 of the Ohio Revised Code. The Corporation may enter into contracts with any indemnitee in furtherance of the provisions of this Article V and may create a trust fund, grant a security interest or use other means (including, without limitation, a letter of credit) to ensure the payment of such amounts as may be necessary to effect indemnification as provided in this Article V.

Section 5. Indemnification of Employees and Agents of the Corporation. The Corporation may, by action of its Board of Directors, authorize one or more officers to grant rights to advancement of expenses to employees or agents of the Corporation on such terms and conditions no less stringent than provided in Section 1 hereof as such officer or officers deem appropriate under the circumstances. The Corporation may, by action of its Board of Directors, grant rights to indemnification and advancement of expenses to employees or agents or groups of employees or agents of the Corporation with the same scope and effect as the provisions of this Article V with respect to the indemnification and advancement of expenses of directors and officers of the Corporation; provided, however, that an undertaking shall be made by an employee or agent only if required by the Board of Directors.

Section 6. Procedures for the Submission of Claims. The Board of Directors may establish reasonable procedures for the submission of claims for indemnification pursuant to this Article V, determination of the entitlement of any person thereto and review of any such determination.

ARTICLE VI

Certificates for Shares

Section 1. Uncertificated Shares. Unless otherwise determined by the Board of Directors, the shares of the Corporation shall be uncertificated shares. The Corporation shall, within a reasonable time after the issuance or transfer of uncertificated shares, send to the registered owner of the shares a written notice containing the information required to be set forth or stated on certificates pursuant to Section 1701.25(A) of the Ohio Revised Code.

Section 2. Transfer of Shares. Shares of the Corporation shall be transferable in the manner prescribed by law and in these Regulations. Transfers of shares of the Corporation shall be made on the books of the Corporation only by the registered holder thereof or by such other person as may under law be authorized to endorse such shares for transfer, or by such shareholder’s attorney thereunto authorized by power of attorney duly executed and filed with the secretary or transfer agent of the Corporation. No transfer of shares shall be valid as against the Corporation for any purpose until it shall have been entered in the share transfer records of the Corporation by an entry showing from and to whom those shares were transferred.

Section 3. Registered Shareholders. A person in whose name shares are of record on the books of the Corporation shall conclusively be deemed the unqualified owner and holder thereof for all purposes and to have capacity to exercise all rights of ownership. Neither the Corporation nor any transfer agent of the Corporation shall be bound to recognize any equitable interest in or claim to such shares on the part of any other person, whether disclosed upon such certificate or otherwise, nor shall they be obliged to see to the execution of any trust or obligation.

ARTICLE VII

Fiscal Year

The fiscal year of the Corporation shall end on December 31 in each year, or on such other date as may be fixed from time to time by the Board of Directors.

ARTICLE VIII

Seal

The Board of Directors may provide a suitable seal containing the name of the Corporation. If deemed advisable by the Board of Directors, duplicate seals may be provided and kept for the purposes of the Corporation.

ARTICLE IX

Amendments

These Regulations may be amended, repealed or otherwise altered, at any meeting of shareholders called for such purpose by the affirmative vote of, or without a meeting by the written consent of, the holders of shares entitling them to exercise a majority of the voting power of the Corporation on such proposal. These Regulations may also be amended, repealed or otherwise altered at any meeting of the Board of Directors at which a quorum is present, by a majority of the members in attendance, except with respect to any provision that by virtue of the Ohio Revised Code, the Articles of Incorporation, or these Regulations requires action solely by the shareholders and subject to the power of the shareholders to change such action.
