SHAREHOLDERS’ MEETINGS

Section 3.1. Place of Meeting. Meetings of the shareholders shall be held at the principal office of the Corporation or at any other place (in or out of the State of Mississippi) the Board of Directors or shareholders may from time to time select.

Section 3.2. Annual Meeting. An annual meeting of the shareholders shall be held on the Wednesday of the last week in February of each year, and each year thereafter if not a legal holiday, but if such date shall be a legal holiday, then on the next secular day following that is not a legal holiday, and the shareholders shall elect a Board of Directors and transact other business; provided, however that the Board of Directors shall have the right to set a different date and/or time of said annual meeting if, in their sole opinion, the best interest of the Corporation shall be served thereby. If an annual meeting has not been called and held within the earlier of six months after the end of the Corporation’s fiscal year or fifteen months after its last annual meeting, on application by any shareholder, the Chancery Court where the Corporation’s principal office (or, if none in this state, its registered office) is located in this state may order a meeting to be held.

Section 3.3. Special Meeting. Special meetings of the shareholders may be called by the Chairman of the Board of Directors (the “Chairman”), President, by a majority of the Board of Directors, or, unless the Restated Articles of Incorporation (the “Articles of Incorporation”) provide otherwise, by the holders of at least ten percent (10%) of the shares outstanding and entitled to vote. No matter shall be proposed for action or other consideration at such meeting except as stated in the notice thereof delivered to the shareholders, unless such notice shall have been unanimously waived, as provided by the Mississippi Business Corporation Act (the “Act”) and these Bylaws, by the shareholders otherwise entitled to notice that such proposed action or other consideration on such matter is a purpose of such special meeting.

Section 3.4. Notice of Meeting. A written or printed notice of each shareholders’ meeting, stating the place, day and hour of the meeting, and in case of a special meeting, the purpose or purposes of the meeting, shall be given by the Secretary of the Corporation or by the person authorized to call the meeting, to each shareholder of record entitled to vote at the meeting. This notice shall be sent at least ten (10) days but not more than sixty (60) days before the date named for the meeting to each shareholder by United States mail, charges prepaid, to the shareholder’s address appearing on the books of the Corporation.

Section 3.5. Waiver of Notice. A shareholder, either before or after a shareholders’ meeting, may waive notice, in writing, of the meeting; and his waiver shall be deemed the equivalent of giving notice. Attendance at a shareholders’ meeting, either in person or by proxy, of a person entitled to notice shall constitute a waiver of notice of the meeting unless he attends for the express purpose of objecting to the transaction of business on the ground that the meeting was not lawfully called or convened.

Section 3.6. Record Date. The Board of Directors may fix in advance a record date for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such record date to be not more than seventy (70) days prior to such meeting. In the absence of any action by the Board of Directors, the date upon which the first notice of the meeting is mailed shall be the record date.

Section 3.7. Shareholders List. After the fixing of a record date for any meeting of shareholders, as provided by Section 3.6 of this Article III, the Secretary of the Corporation shall prepare a complete list of the shareholders who are entitled to notice of such meeting, arranged in alphabetical order, by voting group, and within each voting group by class or series of shares. Such list shall contain the address for and the number of shares held by each shareholder. The shareholders’ list shall be available for inspection by any shareholder beginning two (2) business days after notice of such meeting is given and continuing through such meeting, at the Corporation’s principal office or at a place identified in the meeting notice and in the city where such meeting is to be held. Any shareholder or his agent or attorney shall be entitled upon written demand to inspect and, subject to the requirements of §79-4-16.02(c) of the Act, to copy the list during regular business hours and at such shareholder’s expense during the period such list is available for inspection. The Corporation shall make the shareholders’ list available at the meeting for which such list was prepared, and any shareholder or his agent or attorney shall be entitled to inspect the list at any time during the meeting or any adjournment thereof. Notwithstanding the foregoing, refusal or failure to prepare or make available such list shall not affect the validity of action taken at such meeting.

Section 3.8. Voting Rights. Subject to the provisions of the law of the State of Mississippi, each holder of voting capital stock in this Corporation shall be entitled at each shareholders’ meeting to one vote for every share of stock standing in his name on the books of the Corporation. A majority of the votes cast shall decide every question or matter submitted to the shareholders at any meeting unless otherwise provided by law or by the Articles of Incorporation. Transferees of shares that are transferred on the books of the Corporation within ten days next preceding the date set for a meeting shall not be entitled to notice of, or to vote at, the meeting.

Section 3.9. Proxies. A shareholder entitled to vote may vote in person or by proxy executed in writing by the shareholder or by his attorney in fact. All proxies shall be filed with the records of the meeting. A proxy must be signed and dated in order to be valid. A proxy shall not be valid after eleven months from the date of its execution unless a longer period is expressly stated in the proxy.

A proxy is revocable by the shareholder unless the proxy conspicuously states that it is irrevocable and the proxy is coupled with an interest. An irrevocable proxy coupled with an interest is deemed revoked when the interest with which it is coupled is extinguished. If the name signed on the proxy corresponds to the name of the shareholder, the Corporation, if acting in good faith, is entitled to accept the proxy as the act of the shareholder. When the name signed on the proxy does not correspond to the name of the shareholder, the Corporation, if acting in good faith, is still entitled to accept the proxy as the act of the shareholder if:

(a) the shareholder is an entity and the name signed purports to be that of an officer or agent of the entity;

(b) the name signed purports to be that of an administrator, executor, guardian or conservator representing the shareholder;

(d) the name signed purports to be that of a pledgee, beneficial owner or attorney-in-fact of the shareholder; or

(e) the name signed purports to be that of at least one of the co-owners and the person appears to be acting on behalf of all co-owners.

The Corporation may request evidence, acceptable to the Corporation, that the person signing the proxy, in any capacity, has authority to sign the proxy on behalf of the shareholder. The Corporation, if acting in good faith, is entitled to reject a proxy if there is a reasonable basis for doubt about the validity of the signature or about the signatory’s authority to sign on behalf of the shareholder.

Section 3.10. Quorum. The presence, in person or by proxy, of the holders of at least a majority of the shares outstanding and entitled to vote shall constitute a quorum at a meeting of shareholders; at a duly organized meeting, shareholders present can continue to do business until adjournment even though enough shareholders withdraw to leave less than a quorum.

Section 3.11. Adjournments. Any meeting of shareholders may be adjourned. Notice of the adjourned meeting or of the business to be transacted there, other than by adjournment at the meeting in which the adjournment is taken, shall not be necessary if the new date, time or place is announced at the meeting before adjournment. At an adjourned meeting at which a quorum is present or represented, any business may be transacted which could have been transacted at the meeting originally called.

Section 3.12. Informal Action by Shareholders. Any action that may be taken at a meeting of shareholders may be taken without a meeting if a consent in writing setting forth the action shall be signed by all of the shareholders entitled to vote on the action and shall be filed with the Secretary of the Corporation. This consent shall have the same effect as a unanimous vote at a shareholders’ meeting.

ARTICLE IV.

THE BOARD OF DIRECTORS

Section 4.1. Number, Qualification and Term of Office. The business and affairs of the Corporation shall be managed by a Board of Directors of not less than one (1) nor more than three (3) as shall be elected each year at the annual meeting of shareholders by a majority of the votes cast by those shareholders present and voting, whether in person or by proxy. In addition, a person must meet any and all requirements of the laws of the State of Mississippi, as now existing or hereinafter amended or enacted, to serve on the Board of Directors. At the annual meeting of shareholders, the shareholders shall, immediately following the determination by the Board of Directors or Shareholders of the number of directors to be elected, elect directors. The

term of directors shall expire at the next annual meeting of shareholders following their election. If the Board of Directors is divided into classes, the term of directors shall expire at the annual meeting of shareholders at which the term of the class to which they are elected expires. However, a director will continue to serve until his or her successor is elected and qualified, despite the expiration of that director’s term.

Any shareholder who intends to nominate or to cause to have nominated any candidate for election to the Board of Directors (other than the candidates proposed by the Corporation’s management) shall notify the Corporation in writing. Notification shall be mailed or delivered to the President of the Corporation, at the Corporation’s principal place of business, not less than 14 days nor more than 50 days prior to any meeting of shareholders called for the election of directors. If less than 20 days’ notice of the meeting is given to shareholders, such nominations shall be delivered or mailed to the President, at the Corporation’s principal place of business, not later than the close of business on the seventh day following the day on which the notice of the meeting was mailed. All notifications shall contain the following information:

(a) name and address of proposed nominee;

(b) principal occupation of proposed nominee;

(d) name and address of notifying shareholder; and

(e) number of shares owned and held by proxy by the notifying shareholder.

Nominations for director (other than nominations by the Corporation’s management) not made in accordance with the provisions stated herein may be disregarded by the Chairman of the meeting and votes cast for each such nominees may be disregarded by the vote tellers. In the event the same person is nominated by more than one shareholder, the nomination shall be honored and all shares shall be counted if at least one nomination for that person complies with the provisions stated herein.

Section 4.2. Vacancies. Vacancies on the Board of Directors, including a vacancy resulting from an increase in the number of directors, shall be filled by the shareholders only. Each director so elected shall serve until his successor is elected by the shareholders at the next annual meeting or at a special meeting earlier called for that purpose.

Section 4.3. Compensation. By resolution of the Board of Directors, each director may be paid his expenses, if any, of attending meetings of the Board of Directors or committee meetings of the Board of Directors and may be paid a stated salary as director or a fixed sum for attendance at each meeting of the Board of Directors or committee meetings of the Board of Directors, or both. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 4.4. Removal. At a meeting of shareholders called for that purpose, the entire Board of Directors or any individual director may be removed from office with or without cause by the vote of a majority of the shares entitled to vote at an election of directors. A director shall not be removed from office if a number of votes sufficient to elect the director under cumulative voting is voted against the director’s removal.
