ARTICLE V

INDEMNIFICATION

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 in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he is or was a director or an officer of the Corporation or such director or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans (hereinafter an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Mississippi Business Corporation Act, 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 such law permitted the Corporation to provide prior

to such amendment, against all expense, liability and loss (including but not limited to attorneys fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith. 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; provided, however, that, except as provided in Section 3 of this Article V with respect to proceedings 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 by the Board of Directors of the Corporation.

The right to indemnification conferred in this Article V shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the Mississippi Business Corporation Act requires, an advancement of expenses incurred by an indemnitee in his capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee) 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 shall ultimately be determined by final judicial decision (from which there is no further right to appeal) that such indemnitee is not entitled to be indemnified for such expenses under this Article V or otherwise (hereinafter an “undertaking”). This Article V constitutes the authorization and determination required for the indemnification and advancement of expenses provided hereby and therefore a determination in accordance with Section 79-4-8.55 (a), (b), or (c) of the Mississippi Business Corporation Act, as now existing or hereafter amended, shall not be required before an indemnitee is entitled to indemnification and advancement of expenses.

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 sixty (60) 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 (20) 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 be entitled to be paid also the expense of prosecuting or defending such suit. It shall be a defense to any such action that the indemnitee has not met the applicable standard of conduct set forth in the Mississippi Business Corporations Act (the “applicable standard of conduct”), which makes it permissible under Section 1 of this Article V for the Corporation to indemnify the indemnitee for the amount claimed, but the burden of proving such defense shall be solely on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the indemnitee is proper in the circumstances because he has met the applicable standard of conduct, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the indemnitee has not met the applicable standard of conduct.

SECTION 3. Non-Exclusivity of Rights. The indemnification rights provided by this Article V shall not be deemed exclusive of any other rights to which any person seeking indemnification may be entitled under any statute, the Articles of Incorporation or Bylaws of the Corporation, agreement, contract, vote of stockholders or disinterested directors or pursuant to the direction (howsoever embodied) of any court of competent

jurisdiction or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in this Article V shall be made to the fullest extent permitted by law. The provisions of this Article V shall not be deemed to preclude the indemnification of any person who is not specified in this Article V, but whom the Corporation has the power or obligation to indemnify under the provisions of applicable federal or state law, or otherwise. The indemnification provided by this Article V shall continue as to a person who has ceased to be a director, officer, or employee and shall inure to the benefit of heirs, executors and administrators of such person.

SECTION 4. Insurance. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him, and incurred by him, in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power or the obligation to indemnify him against such liability under the provisions of this Article V.

SECTION 5. Indemnification of Employees and Agents of the Corporation. The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses, to any employee or agent of the Corporation to the fullest extent of the provisions of this Article V with respect to the indemnification and advancement of expenses of directors and officers of the Corporation.
