BYLAWS

ARTICLE I.

MEETINGS OF SHAREHOLDERS

1. Annual Meeting. The annual meeting of the shareholders shall be held at such date, time and place, either within or without the State of Tennessee, as may be designated from time to time by the board of directors.

2. Special Meetings. Special meetings of the shareholders may be called by the president, a majority of the board of directors, or by the holders of not less than one-tenth ( ¹/10) of all the shares entitled to vote on any issue proposed to be considered at such a meeting. The board of directors shall designate the place of a special meeting.

3. Notice of Shareholder Meetings. Written or printed notice stating the place, date, and time of the meeting, and, in the case of a special meeting, the purpose or purposes for which the special meeting is called and the person or persons calling the special meeting, shall be delivered either personally or by mail by or at the direction of the president, the secretary, or the officer or person calling the meeting to each shareholder entitled to vote at the meeting. If mailed, the notice shall be delivered not less than ten (10) days nor more than two (2) months before the date of the meeting, and the notice shall be deemed to be delivered when deposited in the United States mail, postage prepaid, addressed to the shareholder at his address as it appears on the stock transfer books of the Corporation. If delivered personally, the notice shall be delivered not less than ten (10) days nor more than two (2) months before the date of the meeting and shall be deemed to be delivered when actually received by the shareholder.

4. Quorum Requirements. A majority of the shares entitled to vote shall constitute a quorum for the transaction of business. A meeting may be adjourned despite the absence of a quorum, and notice of an adjourned meeting is not necessary if the time and place to which the meeting is adjourned are announced at the meeting at which the adjournment is taken. When a quorum is present at any meeting and votes cast in favor of an action exceed votes cast in opposition to such action, then such action shall constitute corporate action and shall decide any question brought before that meeting, unless the question is one upon which, by express provision of the Corporation’s Articles of Incorporation, these By-Laws, or by the laws of the State of Tennessee, a larger or different vote is required, in which case any such express provision shall govern the decision of that question.

5. Voting and Proxies. Every shareholder entitled to vote at a meeting may do so either in person or by written proxy, which proxy shall be filed with the secretary of the meeting before being voted. Any such proxy shall entitle the holders of that proxy to vote at any adjournment of that meeting, but shall not be valid after the final adjournment of that meeting. No proxy shall be valid after the expiration of eleven (11) months from the date of its execution unless the proxy provides otherwise.

ARTICLE II.

BOARD OF DIRECTORS

A director may waive the right to receive notice before, during, or after a meeting.

5. Quorum and Vote. The presence of a majority of the directors shall constitute a quorum for the transaction of business. A meeting may be adjourned despite the absence of a quorum, and notice of an adjourned meeting is not necessary if the time and place to which the meeting is adjourned are fixed at the meeting at which the adjournment is taken, and if the period of adjournment does not exceed one month in any one adjournment. The vote 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, unless the vote of a greater number is required by the Articles of Incorporation, these By-Laws, or the laws of the State of Tennessee.

6. Executive and Other Committees. The board of directors, by a resolution adopted by a majority of its members, may designate committees, consisting of one or more persons who may or may not be directors, and may delegate to any such committee or committees any and all authority that the board of directors deems desirable, including the right to delegate to an executive committee the power to exercise all the authority of the board of directors (including an Executive Committee), in the management of the affairs and property of the Corporation.

or proceeding, whether civil, criminal, administrative, or investigative (including, without limitation, any action, suit, or proceeding by or in the right of the Corporation to procure a judgment in its favor) (a “Proceeding”) by reason of the fast that he is or was a director, officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, or employee or agent of another Corporation, partnership, joint venture, trust, or other enterprise against all expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with any such Proceedings. This indemnification shall be a contract right and shall include the right to receive payment in advance of any expenses incurred by an Indemnitee in connection with a Proceeding, consistent with the provisions of applicable law as then in effect.

2. Contracts and Funding. The Corporation may enter into contracts with any director, officer, employee, or agent of the Corporation 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.

For purposes of this Article V, references to “other enterprises” shall include employee benefit plans and employee welfare benefit plan; references to “fines” shall include any excise taxes assessed, on a person with respect to any employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee, or agent, of the Corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner not opposed to the best interests of a Corporation.

4. Indemnification Not Exclusive Right. The right of indemnification and advancement of expenses provided in this Article V shall not be exclusive of any other rights to which a person seeking indemnification may otherwise be entitled, under any statute, by-law, agreement, vote of shareholders, or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office. The provisions of this Article V shall inure to the benefit of the heirs and legal representatives of any person entitled to indemnity under this Article V and shall be applicable to Proceedings commenced or continuing after the adoption of this Article V, whether arising from acts or omissions occurring before or after such adoption.

(b) Written Request for Indemnification. To obtain indemnification under this Article V, an Indemnitee shall submit to the Secretary of the Corporation a written request, including such documentation and information as is reasonably available to the Indemnitee and reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification (the “Supporting Documentation”). The determination of the Indemnitee’s entitlement to indemnification shall be made within a reasonable time after receipt by the Corporation of the written request for indemnification together with the Supporting Documentation. The Secretary of the Corporation, promptly upon receipt of such a request for indemnification, shall advise the board of directors in writing that the Indemnitee has requested indemnification.

(c) Procedure for Determination. An Indemnitee’s entitlement to indemnification under this Article V shall be determined:

(ii) if a quorum cannot be obtained under subdivision (i), by majority vote of a committee duly designated by the board of directors (in which designation directors who are parties may participate), consisting solely of two (2) or more directors not at the time parties to the Proceeding;

(iii) by independent special legal counsel:

(A) selected by the board of directors or its committee in the manner prescribed in subdivision (i) or (ii); or
