8.2 Indemnification. The existing rights of the Employee and obligations of Safeco with regard to indemnification of the Employee are not dependent upon Employee’s continued employment or holding an office or directorship with Safeco or an affiliate. To the extent provided as of the Termination Date in the indemnification provisions of Safeco’s articles of incorporation and bylaws and to the maximum extent permitted under the laws of the state of Washington, Employee will be entitled to indemnification, and advancement of expenses, in respect of matters that occurred during the time that he was an officer of Safeco.
