As a condition to any such right of indemnification, the Corporation may require that it be permitted to participate in the defense of any such action or proceeding through legal counsel designated by the Corporation and at the expense of the Corporation.

Section 9.2. Insurance. The Corporation may purchase and maintain insurance on behalf of any such persons whether or not the Corporation would have the power to indemnify such officers and directors against any liability under the laws of the State of Georgia.

Section 9.3. Notice to Shareholders. If any expenses or other amounts are paid by way of indemnification, other than by court order, action by shareholders or by an insurance carrier, the Corporation shall provide notice of such payment to the shareholders in accordance with the provisions of the laws of the State of Georgia.
