suit or proceeding (other than an action by or in the right of the Company) against expenses
(including attorney fees), judgments, fines, penalties and amounts paid in settlement actually and

reasonably believed to be in or not opposed to the best interests of the Company, was not adjudged
liable on the basis of receipt of an improper personal benefit and, with respect to any criminal
action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination

quorum of disinterested directors or a committee of disinterested directors, (2)&nbsp;independent legal

conduct has been met. Indemnification can also be ordered by a court if the court determines that

the required standard of conduct.

seek an advance of expenses to the same extent as a director under (e)&nbsp;above. An officer of the
Company is also entitled to apply for court-ordered indemnification under the Oregon Business
Corporation Act. The Company has also entered into indemnification agreements with certain of the
Company&#146;s directors. The Company has obtained insurance for the protection of its directors and
officers against any liability asserted against them in their official capacities.

permitted for our directors, officers and controlling persons pursuant to our Second Restated
Articles of Incorporation and amendments thereto or Restated Bylaws, 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 us of expenses incurred or paid by a director, officer, or controlling
person 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,

Item 4. Description of Securities.
Not Applicable.
Item 5. Interests of Named Experts and Counsel.
None.
Item 6. Indemnification of Directors and Officers.
Article VII of the Company's Second Restated Articles of Incorporation and Article V of the
Company's Restated Bylaws require indemnification of current or former directors of the Company to
the fullest extent permitted by law. The right to and amount of indemnification will ultimately be
subject to determination by a court that indemnification in the circumstances presented
is consistent with public policy and other provisions of law. It is likely, however, that Article
VII of the Company's Second Restated Articles of Incorporation and Article V of the Company's
Restated Bylaws would require indemnification at least to the extent that indemnification is
authorized by the Oregon Business Corporation Act. The effect of the indemnification provisions
contained in Article VII of the Company's Second Restated Articles of Incorporation, Article V of
the Company's Restated Bylaws and the Oregon Business Corporation Act (the "Indemnification
Provisions") is summarized as follows:
Table of Contents
(a) The Indemnification Provisions grant a right of indemnification in respect of any action,
suit or proceeding (other than an action by or in the right of the Company) against expenses
(including attorney fees), judgments, fines, penalties and amounts paid in settlement actually and
reasonably incurred, if the person concerned acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the Company, was not adjudged
liable on the basis of receipt of an improper personal benefit and, with respect to any criminal
action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination
of an action, suit or proceeding by judgment, order, settlement, conviction or plea of nolo
contendere does not, of itself, create a presumption that the person did not meet the required
standards of conduct.
(b) The Indemnification Provisions grant a right of indemnification in respect of any action
or suit by or in the right of the Company against the expenses (including attorney fees) actually
and reasonably incurred if the person concerned acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the Company, except that no
right of indemnification will be granted if the person is adjudged to be liable to the Company.
(c) Every person who has been wholly successful on the merits of a controversy described in
(a) or (b) above is entitled to indemnification as a matter of right.
(d) The Company may not indemnify a director unless it is determined by (1) a majority of a
quorum of disinterested directors or a committee of disinterested directors, (2) independent legal
counsel or (3) the shareholders that indemnification is proper because the applicable standard of
conduct has been met. Indemnification can also be ordered by a court if the court determines that
indemnification is fair in view of all of the relevant circumstances.
(e) The Company will advance to a director the expenses incurred in defending any action, suit
or proceeding in advance of its final disposition if the director affirms in good faith that he or
she has met the standard of conduct to be entitled to indemnification as described in (a) or (b)
above and undertakes to repay any amount advanced if it is determined that the person did not meet
the required standard of conduct.
Under the Oregon Business Corporation Act, an officer of the Company is entitled to mandatory
indemnification to the same extent as a director of the Company in (c) above if he or she was
wholly successful on the merits of a controversy described in (a) or (b) above, and an officer may
seek an advance of expenses to the same extent as a director under (e) above. An officer of the
Company is also entitled to apply for court-ordered indemnification under the Oregon Business
Corporation Act. The Company has also entered into indemnification agreements with certain of the
Company's directors. The Company has obtained insurance for the protection of its directors and
officers against any liability asserted against them in their official capacities.
The rights of indemnification described above are not exclusive of any other rights of
indemnification to which the persons indemnified may be entitled under any bylaw, agreement, vote
of shareholders or otherwise.
Item 7. Exemption From Registration Claimed.
None.

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. Notwithstanding the foregoing,
any increase or decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation from
the low or high end of the estimated maximum offering range may be reflected in the
form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20 percent change
in the maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective 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 the undertakings set forth in paragraphs (i) and (ii) above do not
apply if the information required to be included in a post-effective amendment by those
paragraphs is contained in reports filed with or furnished to the Commission by the
registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in this 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 of 1933 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
Table of Contents
Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in this 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)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted for our directors, officers and controlling persons pursuant to our Second Restated
Articles of Incorporation and amendments thereto or Restated Bylaws, 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 us of expenses incurred or paid by a director, officer, or controlling
person 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 the registrant is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.
