INDEMNIFICATION

     Section 1. Standard of Conduct. Every person who is or was a director or officer of the Corporation or of any other corporation or entity in which such person served as a director or officer at the request of the Corporation (hereinafter collectively referred to as “Covered Person”), shall in accordance with Section 2 of this Article IV be indemnified by the Corporation against any and all reasonable costs and expenses (including but not limited to attorney fees) and any liabilities (including but not limited to judgments, fines, penalties and reasonable settlements) that may be paid by or imposed against him or her in connection with or resulting from any pending, threatened or completed claim, action, suit or proceeding (whether brought by or in the right of the Corporation or such other corporation or entity or otherwise), and whether civil, criminal, administrative, investigative or legislative (including any appeal relating thereto), in which the Covered Person may be involved, as a party or witness or otherwise, by reason of his or her being or having been a director or officer of the Corporation or a director or officer of such other corporation or entity, or by reason of any action taken or not taken in such capacity,

whether or not the Covered Person continues to be such at the time such liability or expense shall have been paid or imposed, provided the Covered Person acted in good faith, in what he or she reasonably believed to be the best interests of the Corporation or such other corporation or entity, as the case may be, and in addition, in any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. As used in this Article IV, the terms “expense” and “liability” shall include, but shall not be limited to, attorney fees and disbursements and amounts of judgments, fines or penalties against, and reasonable amounts paid in settlement by, a Covered Person. The termination of any claim, action, suit or proceeding by judgment, settlement (whether with or without court approval), conviction or upon a plea of guilty or nolo contendere, or its equivalent, shall not create a presumption that a Covered Person did not meet the standards of conduct set forth in this Section 1.

     Section 2. Indemnification. Every Covered Person who has been, based on a final adjudication rendered by a court of competent jurisdiction, successful on the merits or otherwise with respect to any claim, action, suit or proceeding of the character described in Section 1 shall be entitled to indemnification as a matter of right. Except as provided in the preceding sentence, any indemnification under Section 1 may be made by the Board for any Covered Person or any employee of the Corporation, in the Board’s discretion, but only if either [i] the Board, acting by a quorum consisting of directors who were

not parties to (or who are finally adjudicated by a court of competent jurisdiction to have been successful with respect to) such claim, action, suit or proceeding, shall have found that the Covered Person or employee has met the applicable standard of conduct set forth in Section 1; or [ii] if there be no such disinterested quorum, independent legal counsel (who may be the regular counsel of the Corporation) shall have delivered to the Corporation written advice to the effect that in their judgment such applicable standard has been met. Notwithstanding anything in this Article IV to the contrary, no person shall be indemnified in respect of any claim, action, suit or proceeding initiated by such person or his personal or legal representative, or which involved the voluntary solicitation or intervention of such person or his personal or legal representative (other than an action to enforce indemnification rights hereunder or an action initiated with the approval of a majority of the Board).

     Section 3. Advances. Expenses incurred with respect to any claim, action, suit or proceeding may be advanced by the Corporation prior to the final disposition thereof upon receipt of an undertaking by the director or officer to repay such amount as shall not ultimately be determined to be payable to him or her hereunder.

     Section 4. Insurance. The Corporation, by authorization of the Board of Directors, may purchase and maintain insurance on behalf of any person who is or was a director or officer, against any liability asserted against him or her and incurred in any such capacity, or arising out of his or her

status as such, whether or not the Corporation would have the power to indemnify him or her against such liability under this Article.

     Section 5. Validity. Subject to the limitations provided in this Article, it is the intention of these By-Laws to give the directors and officers the maximum indemnification permitted under the law of the Commonwealth of Kentucky as it now exists or may exist in the future. The rights of indemnification provided hereunder shall not be deemed exclusive of other rights to which any such director or officer now or hereafter may be entitled, shall continue as to a person who has ceased to be a director or officer, and shall inure to the benefit of such person’s heirs and legal representatives. If any provision or portion of this Article shall be found, in any action, suit or proceeding, to be invalid or ineffective, the validity and effect of the remaining parts shall not be affected.

ARTICLE V

Any such resignation shall take affect at the time specified therein, or, if the time be not specified therein, upon its acceptance by the Board of Directors.

     Section 2. Removal. The shareholders, at any meeting called for such purpose, by vote of a majority of the shares issued and outstanding, may remove from office any director and elect his or her successor.

Such certificates shall be signed by the President and by the Secretary. No certificate of shares shall be issued until the shares represented by the certificates have been fully paid.

     Section 2. Transfer. Shares may be transferred by delivery of the certificate accompanied either by an assignment in writing on the back of the certificate or by a written power of attorney to sell, assign, and transfer the same on the books of the Corporation, signed by the person appearing by the certificate to be the owner of the shares represented thereby, together with any necessary federal and state transfer tax stamps affixed, and shall be transferable on the books of the Corporation upon surrender thereof so assigned or endorsed.

In lieu of closing the transfer books, the Board of Directors may fix a day not more than forty (40) days prior to the day of holding any meeting of shareholders as the day as of which shareholders entitled to notice of and to vote at such meeting shall be determined; and only shareholders of record on such day shall be entitled to notice of or to vote at such meeting.

     Section 4. Loss. In case of the loss, mutilation, or destruction of a certificate of shares, a duplicate certificate may be issued upon such terms as the Board of Directors shall prescribe.
