Corporation shall have authority to issue is 30,000,000 shares to be divided
into two classes consisting of 29,000,000 shares of common stock of the par

be stated and expressed in the resolution or resolutions of the Board of
Directors of the Corporation providing for the issue of such shares of Preferred
Stock subject to the following limitations: (a) no share of Preferred Stock
shall have voting powers in excess of one (1) vote per share; provided, however,
if the Preferred Stock is convertible into Common Stock as of a record date on

shares and subject to any restrictions or conditions set forth in the
resolution, be granted the right to vote the number of shares of Common Stock
which would be issued upon such conversion as of the record date; and (b) no
shares of Preferred Stock shall be given a preference over the Common Stock in
the event of any liquidation, dissolution, winding up, merger or consolidation
of an amount greater than the per share fair market value of the consideration
received upon the issuance of the shares of Preferred Stock as reasonably
determined in good faith by the Board of Directors of the Corporation plus
accrued but unpaid dividends.

     The Preferred Stock may be issued in one or more series of stock and each
such series, subject to the limitations set forth above, may have such
designations, preferences, limitations and relative rights as shall be stated
and expressed in a resolution or resolutions providing for the issue of such
Preferred Stock adopted by the Board of Directors pursuant to the authority
hereby granted.

Article VIII hereof (so long as the resolution or resolutions adopting the same
are approved by the unanimous vote of the Board of Directors).

Corporation from time to time for such consideration, not less than the par
value thereof except as otherwise provided by law, as from time to time may be

capital stock of the Corporation shall be deemed fully paid and non-assessable
and the holders of such shares shall not be liable thereunder to the Corporation
or to its creditors.

Person in acquiring any of its holdings of the Corporation's Common Stock or
(ii) an amount which bears the same or a greater percentage relationship to the
Market Price of the Corporation's Common Stock immediately prior to the

guarantees, pledges or other financial assistance or tax credits provided by the
Corporation or a Subsidiary, or made any major changes in the Corporation's

of the Board then in office; and

               (3)  A proxy statement responsive to the requirements of the
Securities Exchange Act of 1934, whether or not the Corporation is then subject
to such requirements, shall be mailed to all shareholders of the Corporation for
the purpose of soliciting shareholder approval of such Major Transaction and
shall contain at the front thereof, in a prominent place any recommendations as
to the advisability (or inadvisability) of the Major Transaction which the
Continuing Directors, or any Outside Directors, may choose to state.

     2.   The Board of Directors of the Corporation shall have the power and 
duty to determine for the purposes of this Article VIII, on the basis of
information known to the Corporation, whether (a) any corporation, person or
other entity "Beneficially Owns," directly or indirectly, more than twenty
percent (20%) of the shares of the Voting Stock, (b) any corporation, person or
other entity is an Affiliate or Associate of another and (c) any proposed sale,
lease, exchange or other disposition of part of the assets of the Corporation or
any of its Affiliates involves a Substantial Part of the assets of the
Corporation or such Affiliate, provided that assets involved in any single
transaction or series of related transactions having an aggregate fair market
value of more than fifteen percent (15%) of the total consolidated assets of the
Corporation and its Affiliates shall always be deemed to constitute a
"Substantial Part" for purposes of this Article VIII. Any such determination
made in good faith shall be conclusive and binding for all purposes of this
Article VIII.

     3.   Nothing contained in this Article VIII shall be construed to relieve 
any Related Person from any fiduciary obligation imposed by law.

     1.   Any purchase by the Corporation of shares of Voting Stock from an
Interested Shareholder, other than pursuant to an offer to the holders of all of
the outstanding shares of the same class of Voting Stock as those so purchased,
at a per share price in excess of the Market Price at the time of such purchase
of the shares so purchased, shall require the affirmative vote of the holders of
that amount of the voting power of the Voting Stock equal to the sum of (i) the
voting power of the shares of Voting Stock of which the Interested Shareholder
is the Beneficial Owner and (ii) a majority of the voting power of the remaining
outstanding shares of Voting Stock, voting together as a single class.

     2.   In addition to any affirmative vote required by law or these Articles
of Incorporation:

          (a)  any merger or consolidation of the Corporation or any Subsidiary
with (1) any Interested Shareholder or (2) any other corporation (whether or not

assets of the Corporation or any Subsidiary having an aggregate Fair Market
value of $2,000,000 or more; or

          (c)  the issuance or transfer by the Corporation or any Subsidiary (in

Corporation or any Subsidiary having an aggregate Fair Market Value of
$2,000,000 or more to any Interested Shareholder or any Affiliate of any
Interested Shareholder in exchange for cash, securities or other property (or a
combination thereof); or

          (d)  the adoption of any plan or proposal for the liquidation or
dissolution of the Corporation proposed by or on behalf of an Interested
Shareholder or any Affiliate of any Interested Shareholder; or

split), or recapitalization of the Corporation, or any merger or consolidation
of the Corporation with any Subsidiary or any other transaction (whether or not
with or into or otherwise involving an Interested Shareholder) which has the
effect, directly or indirectly, of increasing the proportionate share of the
outstanding shares of any class of equity or convertible securities of the
Corporation or any Subsidiary which is directly or indirectly owned by any
Interested Shareholder or any Affiliate of any Interested Shareholder;

shall require either (a) the approval of a majority of the Disinterested
Directors or (b) the affirmative vote of the holders of that amount of voting
power of the Voting Stock equal to the sum of (1) the voting power of the shares
of Voting Stock of which the Interested Shareholder is the Beneficial Owner and
(2) a majority of the voting power of the remaining outstanding shares of Voting
Stock, voting together as a single class; provided, however, that no such vote
shall be required for (i) the purchase by the Corporation of shares of Voting
Stock from an Interested Shareholder unless such vote is required by Section 1
of this Article IX, (ii) any transaction with an Interested Shareholder who is
also a Related Person as defined in Article VII and to which the provisions of
Article VIII apply and are complied with, or (iii) any transaction with an
Interested Shareholder who has Beneficially Owned all his shares of Voting Stock

     3.   At any election of directors of the Corporation on or after the date 
on which any Substantial Shareholder becomes a Substantial Shareholder, and
until such time as there is no longer any Substantial Shareholder, there shall
be cumulative voting for election of directors so that any holder of shares of
Voting Stock entitled to vote in such election shall be entitled to as many
votes as shall equal the number of directors to be elected multiplied by the
number of votes to which such shareholder's shares would be entitled except for
the provisions of this Section 3, and such shareholder may cast all of such
votes for a single director, or distribute such votes among as many candidates
as such shareholder sees fit. In any such election of directors, one or more
candidates for the Board may be nominated by a majority of the Disinterested
Directors and by any person who is the Beneficial Owner of 1% or more of the
outstanding shares of Voting Stock. With respect to any candidates nominated by
a majority of the Disinterested Directors or by any person who is the Beneficial
Owner of 1% or more of the outstanding shares of Voting Stock, there shall be
included in any proxy statement or other communication with respect to such
election to be sent to holders of shares of Voting Stock by the Corporation
during the period in which there is a Substantial Shareholder, at the expense of
the Corporation, descriptions and other statements of or with respect to such
candidates submitted by them or on their behalf, which shall receive equal
space, coverage and treatment as is received by candidates

ownership of the outstanding Voting Stock of which such Interested Shareholder
is a Beneficial Owner, and

          (b)  to notify the Corporation promptly in writing of any change in 
the information provided in subparagraph (a) of this Section 4; provided,
however, that the failure of an Interested Shareholder to comply with the
provisions of this Section 4 shall not in any way be construed to prevent the
Corporation from enforcing the provisions of Sections 1 through 3 of this
Article IX.

     5.   A majority of the Disinterested Directors of the Corporation shall 
have the power and duty to determine for the purposes of this Article IX, on the
basis of information known to them after reasonable inquiry, (a) whether a
person is an Interested Shareholder or a Substantial Shareholder, (b) the number

Disinterested Directors shall be conclusive and binding for all purposes of this
Article IX.

                                    ARTICLE X
                              ELECTION OF DIRECTORS

     1.   The number of directors of the Corporation shall be specified in the
Bylaws, and such number may from time to time be increased or decreased in such
manner as may be prescribed in the Bylaws, provided the number of directors of
the Corporation shall not be less than seven (7).

     2.   Directors shall be classified with respect to the time for which they
shall severally hold office by dividing them into three classes, as nearly equal
in number as possible. Those of the first class shall be elected for a term of
office to expire at the first annual meeting of shareholders after their
election, those of the second class shall be elected for a term of office to
expire at the second annual meeting of shareholders after their election, and
those of the third class shall be elected for a term of office to expire at the
third annual meeting of shareholders after their election. Thereafter, the class
of directors then being elected shall be elected to hold office for a term of
office to expire at the third succeeding annual meeting of shareholders after
their election. Each director shall hold office for the term for which elected
and until such director's successor shall have been elected and qualified.

     3.   At a meeting of shareholders called expressly for that purpose, any
director, any class of directors, or the entire Board of Directors may be
removed from office as a director at any time (a) for cause by the shareholders
entitled to elect such director if the number of votes cast to remove the
director exceeds the number of votes cast not to remove the director, and if
cumulative voting is then in effect, then a director may not be removed if the
number of votes sufficient to elect such director is voted against the
director's removal, or (b) without cause by the affirmative vote which satisfies
the requirements of Article XI applicable to an amendment, modification, or
repeal of certain of these Articles.

     4.   Vacancies in the Board of Directors, including vacancies resulting 
from an increase in the number of directors, shall be filled only by the
affirmative vote of a majority of the remaining directors then in office, though
less than a quorum, or by the sole remaining director. The term of a director
elected to fill a vacancy shall expire at the next annual meeting of
shareholders at which directors are elected. No decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.

     5.   All corporate powers shall be exercised by the Board of Directors 
except as otherwise provided by law or these Articles of Incorporation.

     6.   Except as otherwise provided in these Articles of Incorporation,
shareholders of the Corporation shall not have the right to cumulate votes in
the election of directors.

                                   ARTICLE XI
                       RESTRICTIONS ON CERTAIN AMENDMENTS

     The provisions set forth in this Article XI and in Articles III, VII, VIII,
IX, X and XVII herein may not be repealed or amended in any respect, unless such
action is approved by the affirmative vote of the holders of not less than 80%
of the outstanding shares of Voting Stock of the Corporation, subject to the
provisions of any series of Preferred Stock which may at the time be
outstanding, provided, however, that if there is a shareholder of the
Corporation which is a Related Person, such 80% vote must include the
affirmative vote of at least 50% of the outstanding Voting Stock held by
shareholders other than the Related Person.

                                   ARTICLE XII
                               POWERS OF DIRECTORS

     The directors shall have power to make and to alter or amend the Bylaws and
shall have all such other powers as they may be afforded by applicable law.

                                  ARTICLE XIII
                             LIMITATION OF LIABILITY

     To the fullest extent permitted by the Washington Business Corporation Act
as the same exists or may hereafter be amended, a director of the Corporation
shall not be liable to the Corporation or its shareholders for monetary damages
for conduct as a director. Any amendments to or repeal of this Article XIII
shall not adversely affect any right or protection of a director for or with
respect to any acts or omissions of such director occurring prior to such
amendment or repeal.

                                   ARTICLE XIV
          INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS

     1.   The Corporation shall have the following powers:

          (a)  The Corporation may indemnify and hold harmless to the fullest
extent not prohibited by applicable law each person who was or is made a party
to or is threatened to be made a party to or is involved (including, without
limitation, as a witness) in any actual or threatened action, suit or other
proceeding, whether civil, criminal, derivative, administrative or
investigative, by reason of the fact that he or she is or was a director,
officer, employee or agent of the Corporation or, being or having been such a
director, officer, employee or agent, he or she is or was serving at the request
of the Corporation as a director, officer, employee, agent, trustee, 

                                       10
   11

or in any other capacity of another corporation or of a partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged action or
omission in an official capacity or in any other capacity while serving as a
director, officer, employee, agent, trustee or in any other capacity, against
all expense, liability and loss (including, without limitation, attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) actually or reasonably incurred or suffered by such person in
connection therewith. Such indemnification may continue as to a person who has
ceased to be a director, officer, employee or agent of the Corporation and shall
inure to the benefit of his or her heirs and personal representatives.

          (b)  The Corporation may pay expenses incurred in defending any such
proceeding in advance of the final disposition of any such proceeding; provided,
however, that the payment of such expenses in advance of the final disposition
of a proceeding shall be made to or on behalf of a director, officer, employee
or agent only upon delivery to the Corporation of an undertaking, by or on
behalf of such director, officer, employee or agent, to repay all amounts so
advanced if it shall ultimately be determined that such director, officer,
employee or agent is not entitled to be indemnified under this Article XIV or
otherwise, which undertaking may be unsecured and may be accepted without
reference to financial ability to make repayment.

          (c)  The Corporation may enter into contracts with any person who is 
or was a director, officer, employee or agent of the Corporation in furtherance
of the provisions of this Article XIV and may create a trust fund, grant a
security interest in property of the Corporation, or use other means (including,
without limitation, a letter of credit) to ensure the payment of such amounts as
may be necessary to effect indemnification as provided in this Article XIV.

          (d)  If the Washington Business Corporation Act (the "Act") is amended
in the future to expand or increase the power of the Corporation to indemnify,
to pay expenses in advance of final disposition, to enter into contracts, or to
expand or increase any similar or related power, then, without any further
requirement of action by the shareholders or directors of the Corporation, the
powers described in this Article XIV shall be expanded and increased to the
fullest extent permitted by the Act, as so amended.

          (e)  No indemnification shall be provided under this Article XIV to 
any such person if the Corporation is prohibited by the nonexclusive provisions
of the Act or other applicable law as then in effect from paying such
indemnification. For example, no indemnification shall be provided to any
director in respect of any proceeding, whether or not involving action in his or
her official capacity, in which he or she shall have been finally adjudged to be
liable on the basis of intentional misconduct or knowing violation of law by the
director, or from conduct of the director in violation of Section 23B.08.310 of
the Act, or that the director personally received a benefit in money, property
or services to which the director was not legally entitled.

     2.   The Corporation shall indemnify and hold harmless any person who is or
was a director or officer of the Corporation, and pay expenses in advance of
final disposition of a proceeding, to the full extent to which the Corporation
is empowered.

     3.   The Corporation may, by action of its Board of Directors from time to
time, indemnify and hold harmless any person who is or was an employee or agent
of the Corporation, and pay expenses in advance of final disposition of a
proceeding, to the full extent to which the Corporation is empowered, or to a
lesser extent which the Board of Directors may determine.

     4.   The rights to indemnification and payment of expenses in advance of
final disposition of a proceeding conferred by or pursuant to this Article XIV
shall be contract rights.

                                       11
   12

     5    A director, officer, employee or agent ("claimant") shall be presumed 
to be entitled to indemnification and/or payment of expenses under this Article
XIV upon submission of a written claim (and, in an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its final
disposition, where the undertaking in subsection 1(b) above has been delivered
to the Corporation) and thereafter the Corporation shall have the burden of
proof to overcome the presumption that the claimant is so entitled.

     If a claim under this Article XIV is not paid in full by the Corporation
within sixty (60) days after a written claim has been received by the
Corporation, except in the case of a claim for expenses incurred in defending a
proceeding in advance of its final disposition, in which case the applicable
period shall be twenty (20) days, the claimant may at any time thereafter bring
suit against the Corporation to recover the unpaid amount of the claim and, to
the extent successful in whole or in part, the claimant shall be entitled to be
paid also the expense of prosecuting such claim. Neither the failure of the
Corporation (including its board of directors, its shareholders or independent
legal counsel) to have made a determination prior to the commencement of such
action that indemnification of or reimbursement or advancement of expenses to
the claimant is proper in the circumstances nor an actual determination by the
Corporation (including its board of directors, its shareholders or independent
legal counsel) that the claimant is not entitled to indemnification or to the
reimbursement or advancement of expenses shall be a defense to the action or
create a presumption that the claimant is not so entitled.

     6.   The right to indemnification and payment of expenses in advance of 
final disposition of a proceeding conferred in this Article XIV shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the articles of incorporation, bylaws,
agreement, vote of shareholders or disinterested directors or otherwise.

     7.   The Corporation may purchase and maintain insurance, at its expense, 
to protect itself and any director, officer, employee, agent or trustee of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Act.

     8.   Any repeal or modification of this Article XIV shall not adversely
affect any right of any person existing at the time of such repeal or
modification.

     9.   If any provision of this Article XIV or any application thereof shall
be invalid, unenforceable or contrary to applicable law, the remainder of this
Article XIV, or the application of such provision to persons or circumstances
other than those as to which it is held invalid, unenforceable or contrary to
applicable law, shall not be affected thereby and shall continue in full force
and effect.

     10.  For purposes of this Article XIV, applicable law shall at all times be
construed as the applicable law in effect at the date indemnification may be
sought, or the law in effect at the date of the action, omission or other event
giving rise to the situation for which indemnification may be sought, whichever
is selected by the person seeking indemnification. As of the date hereof,
applicable law shall include Section 23B.08.500 through .600 of the Act.

                                   ARTICLE XV
                MERGERS, SHARE EXCHANGES, AND OTHER TRANSACTIONS

     Except as otherwise expressly provided in these Articles, a merger, share
exchange, sale of substantially all of the Corporation's assets, or dissolution
must be approved by the affirmative vote of a majority of the Corporation's
outstanding shares entitled to vote, or if separate voting by

                                       12
   13

voting groups is required, then by not less than a majority of all the votes
entitled to be cast by that voting group.

                                   ARTICLE XVI
                  CORPORATION'S ACQUISITION OF ITS OWN SHARES

     The Corporation may purchase, redeem, receive, take or otherwise acquire,
own and hold, sell, lend, exchange, transfer or otherwise dispose of, pledge,
use and otherwise deal with and in its own shares. As a specific modification of
Section 231B.06.310 of the Act, pursuant to the authority in Section
23B.02.020(5)(c) of the Act to include provisions related to the management of
the business and the regulation of the affairs of the Corporation, shares of the
Corporation's stock acquired by it pursuant to this Article XVI shall be
considered "Treasury Stock" and so held by the Corporation. The shares so
acquired by the Corporation shall not be considered as authorized and unissued
but rather as authorized, issued, and held by the Corporation. The shares so
acquired shall not be regarded as canceled or as a reduction to the authorized
capital of the Corporation unless specifically so designated by the Board of
Directors in an amendment to these Articles. The provisions of this Article XVI
do not alter or effect the status of the Corporation's acquisition of its shares
as a "distribution" by the Corporation as defined in Section 23B.01.400(6) of
the Act, nor alter or effect the limitations on distributions by the Corporation
as set forth in Section 23B.06.400 of the Act. Any shares so acquired by the
Corporation, unless otherwise specifically designated by the Board of Directors,
at the time of acquisition, shall be considered on subsequent disposition as
transferred rather than reissued. Nothing in this Article XVI limits or
restricts the right of the Corporation to resell or otherwise dispose of any of
its shares previously acquired for such consideration and according to such
procedures as established by the Board of Directors.

                                  ARTICLE XVII
                          SPECIAL SHAREHOLDER MEETINGS

     Special meetings of the shareholders of the Corporation for any purpose or
purposes may be called at any time by the Board of Directors, or by a committee
of the Board of Directors which has been duly designated by the Board of
Directors and whose powers and authority, as provided in a resolution of the
Board of Directors or in the bylaws of the Corporation, include the power to
call such meeting, but such special meetings may not be called by any other
person or persons.

                                  ARTICLE XVIII
                                  INCORPORATOR
