Item 6.
Indemnification of Directors and Officers
.
The Oregon Business Corporation Act (the "Act") provides, in general, that a director or officer of a corporation who has been or is threatened to be made a defendant in a legal proceeding because that person is or was a director or officer of the corporation:
(1) shall be indemnified by the corporation for all expenses of such litigation when the director or officer is wholly successful on the merits or otherwise;
(2) may be indemnified by the corporation for the expenses, judgments, fines and amounts paid in settlement of such litigation (other than a derivative lawsuit) if he or she acted in good faith and in a manner reasonably believed to be in, or at least not opposed to, the best interests of the corporation (and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful); and
(3) may be indemnified by the corporation for expenses of a derivative lawsuit (a suit by a shareholder alleging a breach by a director or officer of a duty owed to the corporation) if he or she acted in good faith and in a manner reasonably believed to be in, or at least not opposed to, the best interests of the corporation, provided the director or officer is not adjudged liable to the corporation.
The Act also authorizes the advancement of litigation expenses to a director or officer upon receipt of a written affirmation of the director's or officer's good faith belief that the standard of conduct in Section (2) or (3) above has been met and an undertaking by such director or officer to repay such expenses if it is ultimately determined that he or she did not meet that standard and, therefore, is not entitled to be indemnified. The Act also provides that the indemnification provided thereunder shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise.
The Company's Amended and Restated Bylaws provide that the Company shall indemnify directors and officers to the fullest extent permitted under the Act, thus making mandatory the discretionary indemnification authorized by the Act.
The Company's Amended and Restated Articles of Incorporation provide that the Company shall indemnify its officers and directors to the fullest extent permitted by law, which may be broader than the indemnification authorized by the Act.
The Company has entered into indemnity agreements with its directors and officers which provide for indemnity to the fullest extent permitted by law and also alter or clarify the statutory indemnity in the following respects:
(1) prompt advancement of litigation expenses is provided if the director or officer makes the required affirmation and undertaking;
(2) the director or officer is permitted to enforce the indemnity obligation in court and the burden is on the Company to prove that the director or officer is not entitled to indemnification;
(3) indemnity is explicitly provided for judgments and settlements in derivative actions;
(4) prompt indemnification is provided unless a determination is made that the director or officer is not entitled to indemnification; and
(5) partial indemnification is permitted if the director or officer is not entitled to full indemnification.
The Company maintains in effect a policy of insurance providing for reimbursement to the Company of payments made to directors and officers as indemnity for damages, judgments, settlements, costs and expenses incurred by them which the Company may be required or permitted to make according to applicable law, common or statutory, or under provisions of its Amended and Restated Articles of Incorporation, Amended and Restated Bylaws or agreements effective under such laws.

Item 8.
Exhibits
.
See the accompanying Exhibit Index for a list of Exhibits to this Registration Statement, which is incorporated by reference herein.
Item 9.
Undertakings
.
(a) The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the
following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)-(g) [Reserved]
(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
