corporation. If a quorum exists, action on a matter, other than election of
directors, is approved by a voting group of shareholders if the votes cast
within the voting group favoring the action exceed the votes cast within the
voting group opposing the action, unless the Articles of Incorporation or the
Washington Business Corporation Act require a greater number of affirmative
votes.

        Section 9. Record Date. For the purpose of determining shareholders
entitled to notice of or to vote at any meeting of shareholders, or any
adjournment thereof or entitled to receive payment of any dividend, the board of
directors may fix in advance a record date for any such determination of
shareholders, such date to be not more than seventy-(70) days prior to the date
on which the particular action requiring such determination of shareholders is

notice of the meeting is mailed or the date on which the resolution of the board
of directors declaring such dividend is adopted, as the case may be, shall be
the record date for such determination of shareholders. When a determination of
shareholders entitled to vote at any meeting of shareholders has been made as

thereof, unless the board of directors fixes a new record date, which it must do
if the meeting is adjourned more than one hundred twenty (120) days after the
