     4.2 Except as otherwise required by The General and Business Corporation Law of Missouri, whenever the holders of shares of stock of the Corporation shall be entitled to vote as a class with respect to any matter, the affirmative vote of a majority of the outstanding shares of such class shall be required to constitute the act of such class.

ARTICLE V

     The number of directors to constitute the Board of Directors shall not be less than three (3) nor more than eleven (11).

request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including an employee benefit plan) against any and all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement incurred by such person in connection with any civil, criminal, administrative or investigative action, suit, proceeding or claim (including an action by or in the right of the Corporation or a subsidiary) by reason of the fact that such person is or was serving in such capacity; provided, however, that no such person shall be entitled to any indemnification pursuant to this subsection 7.2 on account of (a) conduct which is finally adjudged to have been knowingly fraudulent or deliberately dishonest or to have constituted willful misconduct, or (b) an accounting for profits pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended from time to time, or pursuant to a successor statute or regulation.

     7.3 The Corporation may, to the extent that the Board of Directors deems appropriate, make advances of expenses, including attorneys’ fees, incurred prior to the final disposition of a civil, criminal, administrative or investigative action, suit, proceeding or claim (including an action by or in the right of the Corporation or a subsidiary) to any person to whom indemnification is or may be available under this Article; provided, however, that prior to making any advances, the Corporation shall receive a written undertaking by or on behalf of such person to repay such amounts advanced in the event that it shall be ultimately determined that such person is not entitled to such indemnification.

     7.4 The indemnification and other rights provided by this Article shall not be deemed exclusive of any other rights to which a person to whom indemnification is or otherwise may be available (under these Articles of Incorporation or the By-Laws or any agreement or vote of shareholders or disinterested directors or otherwise), may be entitled. The Corporation is authorized to purchase and maintain insurance on behalf of the Corporation or any person to whom indemnification is or may be available against any liability asserted against such person in, or arising out of, such person’s status as director, officer, employee or agent of the Corporation, any of its subsidiaries or another corporation, partnership, joint venture, trust or other enterprise (including an employee benefit plan) which such person is serving at the request of the Corporation.

The indemnification and other rights granted by subsections 7.1 and 7.3 and this subsection 7.5 of this Article shall survive amendment, modification or repeal of this Article, and no such amendment, modification or repeal shall act to reduce, terminate or otherwise adversely affect the rights to indemnification granted hereby, with respect to any expenses, judgments, fines and amounts paid in settlement incurred by a person to whom indemnification is granted under subsection 7.1 of this Article with respect to an action, suit, proceeding or claim that arises out of acts or omissions of such person that occurred prior to the effective date of such amendment, modification or repeal.

     Any indemnification granted by the Board of Directors pursuant to subsection 7.2 of this Article shall inure to the person to whom the indemnification is granted and such person’s heirs, executors, administrators and estate; provided, however, that such indemnification may be changed, modified or repealed, at any time or from time to time, at the discretion of the Board of Directors, and the survival of such indemnification shall be in accordance with terms determined by the Board of Directors.

     7.6 For the purposes of this Article, “subsidiary” shall mean any corporation, partnership, joint venture, trust or other enterprise of which a majority of the voting power, equity or ownership interest is directly or indirectly owned by the Corporation.

Amendments to the Articles of Incorporation shall be made in the manner prescribed by The General and Business Corporation Law of Missouri. The power to make, alter, amend, or repeal the By-Laws of the Corporation shall be vested in the Board of Directors, except as otherwise provided in such By-Laws.
