Item 6. Indemnification of Directors and Officers. Section 317 of the California Corporations Code authorizes a court to award, or a corporation's board of directors to grant, indemnity to directors, officers, employees and other agents of the corporation ("Agents") in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act. Article VII of the Registrant's Restated Articles of Incorporation, as amended (Exhibit 4.1 hereto) authorizes the Registrant to indemnify its Agents, through bylaw provisions, agreements, votes of shareholders or disinterested directors or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the California Corporations Code, subject to the applicable limits set forth in Section 204 of the California Corporations Code with respect to actions for breach of duty to the Registrant and its shareholders. Article VII also authorizes the Registrant to provide insurance for Agents provided that, in cases where the Registrant owns all or a portion of the shares of the company issuing the insurance policy, such company and/or the policy must meet certain conditions set forth in Section 317. Article V of the Registrant's Bylaws provides for mandatory indemnification of each director of the Registrant except as prohibited by law. The Registrant maintains a directors and officers liability insurance policy that indemnifies the Registrant's directors and officers against certain losses in connection with claims made against them for certain wrongful acts. In addition, the Registrant has entered into separate indemnification agreements with its directors and officers that require the Registrant, among other things, (i) to maintain directors' and officers' insurance in reasonable amounts in favor of such individuals, and (ii) to indemnify them against certain liabilities that may arise by reason of their status or service as Agents of the Registrant to the fullest extent permitted by California law.
