         Section  1.      Annual Meetings.  The annual meeting of the
shareholders of this corporation, for the purpose of election of directors and
for such other business as may come before it, shall be held at the registered

notice of the meeting, on the 100 day of each and every year, at 10 a.m., but
in case such day shall be a legal holiday, the meeting shall be held at the
same hour and place on the next succeeding day not a holiday.

         Section  2.      Special Meetings. Special meetings of the
shareholders of this corporation may be called at any time by the holders of

special meeting of shareholders except as is specified in the notice calling
for said meeting.  The Board of Directors may designate any place as the place
of any special meeting called by the President or the Board of Directors, and
special meetings called at the request of shareholders shall be held at such
place as may be determined by the Board of Directors and placed in the notice
of such meetings.

         Section  3.       Notice of Meetings.  Written notice of annual or
special meetings of shareholders stating the place, day, and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for

authorized to call the meeting to each shareholder of record entitled to vote
at the meeting.  Such notice shall be given not less than ten (10) days nor
more
   2
than sixty (60) days prior to the date of the meeting, except that notice of a
meeting to act on an amendment to the Articles of Incorporation, a plan of
merger or share exchange, a proposed sale, lease, exchange, or other
disposition of all or substantially all of the assets of the corporation other
than in the usual or regular course of business, or the dissolution of the
corporation shall be given no fewer than twenty (20) days or no more than sixty
(60) days before the meeting date.  Notice may be transmitted by: mail, private
carrier or personal delivery; telegraph or teletype; or telephone, wire, or
wireless equipment which transmits a facsimile of the notice.  If mailed, such
notice shall be deemed to be delivered when deposited in the United States mail
addressed to the shareholder at his address as it appears on the stock transfer
books of the corporation.

         Section  4.      Waiver of Notice.  Notice of the time, place and
purpose of any meeting may be waived in writing (either before or after such
meeting) and will be waived by any shareholder by his attendance thereat in
person or by proxy, unless the shareholder, at the beginning of the meeting
objects to holding the meeting or transacting business at the meeting.  Any
shareholder so waiving shall be bound by the proceedings of any such meeting in
all respects as if due notice thereof had been given.

         Section  5.      Quorum and Adjourned Meetings.  A majority of the
outstanding shares of the corporation entitled to vote, represented in person
or by proxy, shall constitute a quorum at a meeting of shareholders.  A
majority of the shares represented at a meeting, even if less than a quorum,
may adjourn the meeting from time to time without further notice.  At such
reconvened meeting at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at a duly organized
meeting and at any adjournment of such meeting (unless a new record date is or
must be set for the adjourned meeting), notwithstanding the withdrawal of
enough shareholders from either meeting to leave less than a quorum.

         Section  6.      Proxies.  At all meetings of shareholders, a
shareholder may vote by proxy executed in writing by the shareholder or by his
duly authorized attorney in fact.  Such proxy shall be filed with the secretary
of the corporation before or at the time of the meeting.  No proxy shall be
valid after eleven (11) months from the date of its execution, unless otherwise
provided in the proxy.

         Section  7.      Voting Record.  After fixing a record date for a
shareholders' meeting, the corporation shall prepare an alphabetical list of
the names of all shareholders on the record date who are entitled to notice of
the shareholders' meeting.  The list shall be arranged by voting group, and
within each voting group by class or series of shares, and show the address of
and number of shares held by each shareholder.  A shareholder, shareholder's
agent, or a shareholder's attorney may inspect the shareholder's list,
beginning ten (10) days prior to the


                                     -2-
   3

shareholders' meeting and continuing through the meeting, at the corporation's
principal office or at a place identified in the meeting notice in the city
where the meeting will be held during regular business hours and at the
shareholder's expense.  The shareholders' list shall be kept open for
inspection during such meeting or any adjournment.

         Section  8.      Voting of Shares.  Except as otherwise provided in
the Articles of Incorporation or in these Bylaws, every shareholder of record
shall have the right at every shareholders' meeting to one vote for every share
standing in his name on the books of the 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 shareholder, 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 to be taken.  If no record date is fixed for the determination
of shareholders entitled to notice of or to vote at a meeting of shareholders,
or shareholders entitled to receive payment of a dividend, the day before the
date on which 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 provided in this section, such determination
shall apply to any adjournment 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 date is fixed for the original meeting.
