PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.    Incorporation of Documents by Reference.

        The following documents filed with the Commission are incorporated herein by reference:

        All documents filed by the Registrant pursuant to Section 13(a), 13(c), 14 and 15(d) of the Exchange Act after the date hereof, and prior to the filing of a post-effective amendment which indicates that the securities offered hereby have been sold or which deregisters the securities covered hereby then remaining unsold, shall also be deemed to be incorporated by reference into this Registration Statement and to be a part hereof commencing on the respective dates on which such documents are filed.

        Any statement contained in this Registration Statement, or in a document incorporated or deemed to be incorporated by reference herein, shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein, or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein, modifies or supersedes such statement.

Item 4.    Description of Securities.

        Not Applicable


Item 5.    Interests of Named Experts and Counsel.

        Not Applicable


Item 6.    Indemnification of Directors and Officers.

        The Washington Business Corporation Act permits and the Restated Articles of Incorporation and Bylaws of the Registrant provide that to the fullest extent allowed by applicable laws existing from time to time, any person may, and directors and officers shall, be indemnified or reimbursed by the Registrant for reasonable expenses (including attorneys' fees) actually incurred in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative to which he or she shall be made a party or threatened to be made a party by reason of his or her being or having been a director, officer, employee or agent of the Registrant or of any firm, corporation, employee benefit plan or other organization which he or she served in any such capacity at the request of the Registrant; provided, however, that no person shall be so indemnified or reimbursed (1) in relation to any matter in such action, suit or proceeding as to which he or she shall finally be adjudged to have been guilty or liable for gross negligence, willful misconduct or criminal acts in the performance of his or her duties to the Registrant; or (2) in relation to any matter in such action, suit or proceeding which has been made the subject of a compromise settlement except with the approval

3



of (a) a court of competent jurisdiction, (b) the holders of record of a majority of the outstanding shares of the Registrant or (c) the Board of Directors, acting by vote of a majority of directors not parties to the same or substantially the same action, suit or proceeding, whether or not such majority constitutes a quorum. The foregoing right of indemnification or reimbursement is not exclusive of other rights to which such person, his or her heirs, executors or administrators may be entitled as a matter of law. Persons indemnified are deemed to include the heirs, legal representatives, executors and administrators of such persons.

        Expenses (including attorneys' fees) incurred in defending a civil or criminal action, suit or proceeding shall be paid by the Registrant in advance of the final disposition of such action, suit or proceeding. The director, officer, employee or agent must repay such amount, however, if it shall ultimately be determined that he or she is not entitled to be indemnified by the Registrant.

        The Registrant's Restated Articles of Incorporation also provide that a director of the Registrant shall not be personally liable to the Registrant or its shareholders for monetary damages for conduct as a director, except for liability of the director for (i) acts or omissions that involve intentional misconduct or a knowing violation of law by the director, (ii) conduct which violates RCW 23B.08.310 of the Washington Business Corporation Act pertaining to unpermitted distributions to shareholders or loans to directors or (iii) any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled. If the Washington Business Corporation Act is amended to further eliminate or limit the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the fullest extent permitted by the Washington Business Corporation Act, as so amended. Any repeal or modification of the foregoing paragraph by the shareholders of the Registrant shall not adversely affect any right or protection of a director of the Registrant existing at the time of such repeal or modification.
