the Chairman,  the  President,  any Executive Vice President or the Secretary of
this  corporation  or  shareholders  owning  aggregate at least 10% of all votes
entitled  to be cast on any issue  proposed  to be  considered  at the  proposed

                                   ARTICLE IV

     The number of directors which shall constitute the whole board of directors

                                    ARTICLE V

     The board of directors shall be divided into three classes:  Class I, Class

as  possible.  Each  director  shall serve for a term ending at the third annual

elected.  The  directors,  the class to which they are elected,  and the year in
which their term expires, are as follows:

                  Director          Class            Year in Which Term Expires
         ----------------------------------------------------------------------
         James D. Sinegal              I                   2000
         Jeffrey H. Brotman            I                   2000
         Richard A. Galanti            I                   2000
         Hamilton E. James             II                  2001
         Frederick O. Paulsell, Jr.    II                  2001
         Jill A. Ruckelshaus           II                  2001
         Benjamin S. Carson            II                  2001

         Richard D. DiCerchio          III                 2002



     At each annual election,  the directors chosen to succeed those whose terms
then expire shall be identified as being of the same class as the directors they
succeed,  unless, by reason of any intervening  changes in the authorized number
of directors,  the board of directors shall designate one or more  directorships
whose terms then expire as  directorships  of another class in order more nearly
to achieve equality in the number of directors among the classes. When the board
of directors fills a vacancy resulting from the death, resignation or removal of
a director,  the director chosen to fill that vacancy shall be of the same class
as the director he succeeds.

     Notwithstanding any of the foregoing provisions of Article V, in all cases,
including upon any change in the authorized  number of directors,  each director
then continuing to serve as such will nevertheless continue as a director of the
class of which he is a member,  until the  expiration of his current term or his
earlier death,  resignation or removal. Any vacancy to be filled by reason of an
increase in the number of directors  may be filled by the board of directors for
a term of office  continuing  only until the next  election of  directors by the
shareholders.

     Notwithstanding  anything contained in this Article V to the contrary,  the
classification  of  directors  as provided  in this  Article V may be altered or
eliminated  only by an amendment to this Article  approved by  two-thirds of the
votes  entitled  to be  cast  by  each  voting  group  entitled  to vote on such
amendment.

                                   ARTICLE VI

     A  director  of this  corporation  shall  not be  personally  liable to the
corporation or its  shareholders for monetary damages for conduct as a director,
except for  liability of the  director  (i) for acts or  omissions  that involve
intentional  misconduct  by the  director or a knowing  violation  of law by the
director,  (ii) for conduct violating RCW 23B.08.310 of the Washington  Business
Corporation  Act,  or (iii) for 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 in the future to  authorize  corporate  action  further  eliminating  or
limiting the personal  liability of directors,  then the liability of a director
of this corporation  shall be eliminated or limited to the full extent permitted
by  the  Washington  Business  Corporation  Act,  as  so  amended,  without  any
requirement of further action by the shareholders.

                                   ARTICLE VII

     The corporation shall indemnify any individual made a party to a proceeding
because  that  individual  is or was a  director  of the  corporation  and shall
advance or reimburse  the  reasonable  expenses  incurred by such  individual in
advance  of  final  disposition  of  the



proceeding,  without  regard  to  the  limitations  in  RCW  23B.08.510  through
23B.08.550 of the Washington  Business  Corporation Act, or any other limitation
which may hereafter be enacted to the extent such  limitation may be disregarded
if authorized by the Articles of Incorporation, to the full extent and under all
circumstances permitted by applicable law.

     Any repeal or  modification  of this  Article by the  shareholders  of this
corporation shall not adversely affect any right of any individual who is or was
a  director  of the  corporation  which  existed  at the time of such  repeal or
modification.

                                  ARTICLE VIII

     Subject to the rights of  holders  of any  series of  Preferred  Stock then
outstanding, any director, or the entire board of directors, may be removed from
office  only for  cause and only by the  affirmative  vote of the  holders  of a
majority of the voting power of all shares of this corporation  entitled to vote
for the  election of  directors.  As used  herein,  "for cause" means either (i)
conviction of a felony by a court of competent  jurisdiction and such conviction
is no longer subject to direct appeal or (ii)  adjudication for gross negligence
or dishonest conduct in the performance of a director's duty to this corporation
by a court of competent  jurisdiction and such adjudication is no longer subject
to direct appeal.  Notwithstanding anything to the contrary, this Article may be
altered or eliminated  only by amendment to this Article  approved by two-thirds
of the votes  entitled to be cast by each voting group  entitled to vote on such
amendment.

                                   ARTICLE IX

     Amendment of the articles of incorporation, approval of a plan of merger or
share exchange,  authorization of the sale, lease, exchange or other disposition
of all, or substantially  all of the corporation's  property,  otherwise than in
the usual and regular course of business,  and  authorization of the dissolution
of the  corporation,  shall be approved by each  voting  group  entitled to vote
thereon by a simple majority of all the votes entitled to be cast by that voting
group.
