                           AMENDED AND RESTATED BYLAWS
                                       OF
                                    CRAY INC.

                                    SECTION 1

                     SHAREHOLDERS AND SHAREHOLDERS' MEETINGS

          1.1 Annual Meeting. The annual meeting of the shareholders of this
corporation (the "Corporation") for the election of directors and for the
transaction of such other business as may properly come before the meeting shall
be held each year at the principal office of the Corporation, or at some other
place either within or without the State of Washington as designated by the
Board of Directors, on the day and at the time specified in Exhibit A, which is
attached hereto and incorporated herein by this reference, or on such other day
and time as may be set by the Board of Directors. If the specified day is a
Sunday or a legal holiday, then the meeting will take place on the next business
day at the same time or on such other day and time as may be set by the Board of
Directors.

          1.2 Special Meetings. Special meetings of the shareholders for any
purpose or purposes may be called at any time by the Chairman of the Board, the
President or a majority of the Board of Directors. Further, for so long as the
Corporation is a "public company" under Title 23B RCW, a special meeting of the
shareholders shall be held if the holders of not less than 30% of all the votes
entitled to be cast on the issue proposed to be considered at such special
meeting have dated, signed and delivered to the Secretary one or more written
demands for such meeting, describing the purpose or purposes for which it is to
be held; provided, however, that if the Corporation is not a "public company"
under Title 23B RCW, the percentage of votes required to call a special meeting
shall be 25%. The meetings shall be held at such time and place as the Board of
Directors may prescribe, or, if not held upon the request of the Board of
Directors, at such time and place as may be established by the Chairman of the
Board or the President, as applicable, or by the Secretary in the absence of the
Chairman and President.

          1.3 Notice of Meetings. Notice of the place, date and time of the
annual shareholders' meeting and notice of the place, date, time and purpose or
purposes of special shareholders' meetings shall be delivered not less than 10
(or, if required by Washington law, 20) or more than 60 days before the date of
the meeting, either personally, by facsimile, by mail, by electronic
transmission in accordance with applicable law, or in any other manner approved
by law, by or at the direction of the Chairman, the President or the Secretary,
to each shareholder of record entitled to notice of such meeting. Mailed notices
shall be deemed to be delivered when deposited in the mail, first-class postage
prepaid, correctly addressed to the shareholder's address shown in the
Corporation's current record of shareholders. Notice given in any other manner
shall be deemed effective when and as provided under applicable law.



          1.4 Waiver of Notice. Except where expressly prohibited by law or the
Restated Articles of Incorporation, notice of the place, date, time and purpose
or purposes of any shareholders' meeting may be waived either before or after
the meeting. Such waiver may be provided by the shareholder to the Corporation
either (a) in an executed and dated written record or (b) if the Corporation has
designated an address, location or system to which such waiver may be
electronically transmitted and such waiver is electronically transmitted to such
designated address, location, or system, in an executed and dated electronically
transmitted record. Attendance at the meeting in person or by proxy waives
objection to lack of notice or defective notice of the meeting unless the
shareholder at the beginning of the meeting objects to holding the meeting or
transacting business at the meeting. A shareholder waives objection to
consideration of a particular matter at a meeting that is not within the purpose
or purposes described in the meeting notice, unless the shareholder objects to
considering the matter when it is presented.

          1.5 Shareholders' Action Without a Meeting. The shareholders may take
any action without a meeting that they could properly take at a meeting, if one
or more consents setting forth the action so taken are executed by all of the
shareholders entitled to vote with respect to the subject matter and are
delivered to the Corporation for inclusion in the minutes or filing with the
corporate records. Any consent, or subsequent withdrawal of such consent,
delivered to the Corporation shall be (a) in an executed record or (b) if the
Corporation has designated an address, location, or system to which the consent
may be electronically transmitted and the consent is electronically transmitted
to the designated address, location, or system, in an executed electronically
transmitted record. If required by Washington law, all nonvoting shareholders
must be given notice of the proposed action at least 10 days before the action
is taken, unless such notice is waived in a manner consistent with these Bylaws.
Any such notice shall be in such form as may be required by applicable law.
Actions taken under this section are effective when all consents are in the
possession of the Corporation, unless otherwise specified in the consent. A
shareholder may withdraw consent only by delivering notice of withdrawal to the
Corporation prior to the time that all consents are in the possession of the
Corporation and such notice of withdrawal is in the form set forth above.

          1.6 Telephone Meetings. Shareholders may participate in a meeting of
shareholders by means of a conference telephone or any similar communications
equipment that enables all persons participating in the meeting to hear each
other during the meeting. Participation by such means shall constitute presence
in person at a meeting.

          1.7 List of Shareholders. At least 10 days before any shareholders'
meeting, the Secretary of the Corporation or the agent having charge of the
stock transfer books of the Corporation shall have prepared an alphabetical list
of the names of the shareholders on the record date who are entitled to notice
of a shareholders' meeting, arranged by voting group, and within each voting
group, by class or series of shares, and showing the address of and number of
shares held by each shareholder.

          1.8 Quorum and Voting. The presence in person or by proxy of the
holders of a majority of the votes entitled to be cast on a matter at a meeting
shall constitute a quorum of


                                       2



shareholders for that matter. If a quorum exists, action on a matter shall be
approved by a voting group if the votes cast within a voting group favoring the
action exceed the votes cast within the voting group opposing the action, unless
a greater number of affirmative votes is required by the Restated Articles of
Incorporation or by Washington law. If the Restated Articles of Incorporation or
Washington law provide for voting by two or more voting groups on a matter,
action on a matter is taken only when voted upon by each of those voting groups
counted separately. Action may be taken by one voting group on a matter even
though no action is taken by another voting group.

          1.9 Adjourned Meetings. If a shareholders' meeting is adjourned to a
different place, date or time, whether for failure to achieve a quorum or
otherwise, notice need not be given of the new place, date or time if the new
place, date or time is announced at the meeting before adjournment. When a
determination of shareholders entitled to vote at any meeting of shareholders
has been made as provided in these Bylaws, that determination shall apply to any
adjournment thereof, unless Washington law requires fixing a new record date. If
Washington law requires that a new record date be set for the adjourned meeting,
notice of the adjourned meeting must be given to shareholders as of the new
record date. Any business may be transacted at an adjourned meeting that could
have been transacted at the meeting as originally called.

          1.10 Proxies. A shareholder may appoint a proxy to vote or otherwise
act for the shareholder by (a) executing a writing authorizing another person or
persons to act for the shareholder as proxy or (b) transmitting or authorizing
the transmission of an electronic transmission which contains or is accompanied
by information from which it can be reasonably verified that the transmission
was authorized by the shareholder or by the shareholder's attorney-in-fact. The
Corporation shall require the holders of proxies by transmission to provide to
the Corporation copies of the transmission and the Corporation shall retain
copies of the transmission for at least 60 days after the election. No
appointment shall be valid after 11 months from the date of its execution unless
the appointment form expressly so provides. An appointment of a proxy is
revocable unless the appointment is coupled with an interest. No revocation
shall be effective until notice thereof has actually been received by the
Secretary of the Corporation or any other person authorized to tabulate votes
and such notice of revocation is given by (a) executing a writing revoking the
proxy or (b) transmitting or authorizing the transmission of an electronic
transmission which contains or is accompanied by information from which it can
be reasonably verified that the transmission was authorized by the shareholder
or by the shareholder's attorney-in-fact.

          1.11 Business for Shareholders' Meetings.

               1.11.1 Business at Annual Meetings.

                    (a) In addition to the election of directors, other proper
business may be transacted at an annual meeting of shareholders, provided that
such business is properly brought before such meeting. To be properly brought
before an annual meeting business must be (i) brought by or at the direction of
the Board or (ii) brought before the meeting


                                        3



by a shareholder by inclusion in the Corporation's proxy statement pursuant to
the provisions of Rule 14a-8 under Section 14 of the Securities Exchange Act of
1934, as amended, or any successor provision, when and if such Rule is
applicable thereto, or if such business is not so included in the Corporation's
proxy statement, only pursuant to written notice thereof in accordance with
subsection 1.12 hereof, and received by the Secretary not fewer than 60 nor more
than 90 days prior to the date of such annual meeting (or, if less than 60 days'
notice or prior public disclosure of the date of the annual meeting is given or
made to the shareholders, not later than the close of business on the tenth
business day following the day on which such notice of the date of the annual
meeting was mailed or such public disclosure was made, whichever first occurs).

                    (b) Any such shareholder notice shall set forth (i) the name
and address of the shareholder proposing such business; (ii) a representation
that the shareholder is entitled to vote at such meeting; (iii) a statement of
the number of shares of the Corporation which are beneficially owned by the
shareholder and the date upon which such shares were acquired; (iv) a
representation that the shareholder intends to appear in person or by proxy at
the meeting to propose such business; and (v) as to each matter the shareholder
proposes to bring before the meeting, a brief description of the business
desired to be brought before the meeting, the reasons for conducting such
business at the meeting, the language of the proposal (if appropriate), and any
material interest of the shareholder in such business.

                    (c) No business shall be conducted at any annual meeting of
shareholders except in accordance with this subsection 1.11.1. If the facts
warrant, the Board, or the chairman of an annual meeting of shareholders, may
determine and declare that (i) a proposal does not constitute proper business to
be transacted at the meeting or (ii) the business was not properly brought
before the meeting in accordance with the provisions of this subsection 1.11.1
and if, in either case, it is so determined, any such business shall not be
transacted.

               1.11.2 Business at Special Meetings. At any special meeting of
the shareholders, only business within the purpose or purposes described in the
meeting notice required by Section 1.3 may be conducted.

          1.12 Notice to Corporation. Any written notice required to be
delivered by a shareholder to the Corporation pursuant to section 1.2 or section
1.11 hereof must be given, either by personal delivery or by registered or
certified mail, postage prepaid, to the Secretary at the Corporation's principal
office.

                                    SECTION 2

                               BOARD OF DIRECTORS

          2.1 Number and Qualification. The business affairs and property of the
Corporation shall be managed under the direction of a Board of Directors, the
number of members of which is hereby set at nine (9). A member of the Board of
Directors does not need to be a shareholder of the Corporation or a Washington
resident.


                                       4



          2.2 Election--Term of Office.

               2.2.1 The directors shall be elected by the shareholders at each
annual shareholders' meeting or at a special shareholders' meeting called for
such purpose.

               2.2.2 The term of office of a director shall commence effective
immediately upon election, unless otherwise specified in a resolution approved
by the shareholders in connection with the election of such director, and shall
expire at the next annual shareholders' meeting following their election.
Notwithstanding any of the foregoing provisions of this Section 2.2.2, directors
shall serve until their successors are elected and qualified or until their
earlier death, resignation or removal from office, or until there is a decrease
in the number of directors; provided, however, that no decrease in the number of
directors shall have the effect of shortening the term of any incumbent
director.

          2.3 Nominations.

               2.3.1 Only persons who are nominated in accordance with the
following procedures shall be eligible for election as directors by the
shareholders. Nominations for the election of directors may be made (a) by or at
the direction of the Board or (b) by any shareholder of record entitled to vote
for the election of directors at such meeting; provided, however, that a
shareholder may nominate persons for election as directors only if written
notice (in accordance with section 1.12 hereof) of such shareholder's intention
to make such nominations is received by the Secretary not later than (i) with
respect to an election to be held at an annual meeting of the shareholders, not
fewer than 60 nor more than 90 days prior to the date of such annual meeting
(or, if less than 60 days' notice or prior public disclosure of the date of the
annual meeting is given or made to the shareholders, not later than the close of
business on the tenth business day following the day on which such notice of the
date of the annual meeting was mailed or such public disclosure was made,
whichever first occurs) and (ii) with respect to an election to be held at a
special meeting of the shareholders for the election of directors, the close of
business on the tenth business day following the date on which notice of such
meeting is first mailed to shareholders.

               2.3.2 Any such shareholder's notice shall set forth (a) the name
and address of the shareholder who intends to make a nomination; (b) a
representation that the shareholder is entitled to vote at such meeting; (c) a
statement of the number of shares of the Corporation which are beneficially
owned by the shareholder and the dates upon which such shares were acquired; (d)
a representation that the shareholder intends to appear in person or by proxy at
the meeting to nominate the person or persons specified in the notice; (e) as to
each person the shareholder proposes to nominate for election or reelection as a
director, the name and address of such person and such other information
regarding such nominee as would be required in a proxy statement filed pursuant
to the proxy rules of the Securities and Exchange Commission had such nominee
been nominated by the Board, and a description of any arrangements or
understandings, between the shareholder and such nominee and any other


                                       5



persons (including their names), pursuant to which the nomination is to be made;
and (f) the consent of each such nominee to serve as a director if elected.

               2.3.3 If the facts warrant, the Board, or the chairman of a
shareholders' meeting at which directors are to be elected, shall determine and
declare that a nomination was not made in accordance with the foregoing
procedure and, if it is so determined, the defective nomination shall be
disregarded. The right of shareholders to make nominations pursuant to the
foregoing procedure is subject to the rights of the holders of any class or
series of stock having a preference over the Common Stock as to dividends or
upon liquidation. The procedures set forth in this section 2.3 for nomination
for the election of directors by shareholders are in addition to, and not in
limitation of, any procedures now in effect or hereafter adopted by or at the
direction of the Board or any committee thereof.

          2.4 Removal.

               2.4.1 Any director or the entire Board of Directors may be
removed only for cause and only by the holders of not less than two-thirds of
the shares entitled to elect the director or directors whose removal is sought.
Such action may only be taken at a special meeting of the shareholders called
expressly for that purpose, provided that notice of the proposed removal, which
shall include a statement of the charges alleged against the director, shall
have been duly given to the shareholders together with or as a part of the
notice of the meeting.

               2.4.2 The vacancy created by the removal of a director under this
section 2.4 shall be filled only by a vote of the holders of two-thirds of the
shares then entitled to elect the director removed. Such vote may be taken at
the same meeting at which the removal of such director was accomplished, or at
such later meeting, annual or special, as the shareholders may decide.

          2.5 Vacancies. Subject to the provisions of section 2.4 hereof and
unless the Restated Articles of Incorporation provide otherwise, vacancies in
the Board of Directors, whether caused by resignation, death, retirement,
disqualification, increase in the number of directors, or otherwise, may be
filled for the remainder of the term by the Board of Directors, by the
shareholders, or, if the directors in office constitute less than a quorum of
the Board of Directors, by an affirmative vote of a majority of the remaining
directors. The term of a director elected to fill a vacancy expires upon the
election and qualification of his or her successor. A vacancy that will occur at
a specific later date may be filled before the vacancy occurs, but the new
director may not take office until the vacancy occurs.

          2.6 Quorum and Voting. At any meeting of the Board of Directors, the
presence in person (including presence by electronic means such as a telephone
conference call) of a majority of the number of directors presently in office
shall constitute a quorum for the transaction of business. Notwithstanding the
foregoing, in no case shall a quorum be less than one-third of the authorized
number of directors. If a quorum is present at the time of a vote, the
affirmative vote of a majority of the directors present at the time of the vote
shall be the act of the


                                       6



Board of Directors and of the Corporation except as may be otherwise
specifically provided by the Restated Articles of Incorporation, by these
Bylaws, or by law. A director who is present at a meeting of the Board of
Directors when action is taken is deemed to have assented to the action taken
unless: (a) the director objects at the beginning of the meeting, or promptly
upon his or her arrival, to holding it or to transacting business at the
meeting; (b) the director's dissent or abstention from the action taken is
entered in the minutes of the meeting; or (c) the director delivers written
notice of his or her dissent or abstention to the presiding officer of the
meeting before its adjournment or to the Corporation within a reasonable time
after adjournment of the meeting. The right of dissent or abstention is not
available to a director who votes in favor of the action taken.

          2.7 Regular Meetings. Regular meetings of the Board of Directors shall
be held at such place, date and time as shall from time to time be fixed by
resolution of the Board.

          2.8 Special Meetings. Special meetings of the Board of Directors may
be held at any place and at any time and may be called by the Chairman of the
Board, the President, Vice President, Secretary or Treasurer, or any two or more
directors.

          2.9 Notice of Meetings.

               2.9.1 Unless the Restated Articles of Incorporation provide
otherwise, any regular meeting of the Board of Directors may be held without
notice of the date, time, place, or purpose of the meeting. Any special meeting
of the Board of Directors must be preceded by at least two days' notice of the
date, time, and place of the meeting, but not of its purpose, unless the
Restated Articles of Incorporation or these Bylaws require otherwise. Each
director shall have a mailing address, telephone number and facsimile number on
record with the Corporation for purposes of receiving notice.

               2.9.2 Notice may be given personally, by facsimile, by mail, by
electronic transmission in accordance with applicable law, or in any other
manner allowed by law. Oral notice shall be sufficient only if a written record
of such notice is included in the Corporation's minute book. Notice shall be
deemed effective at the earliest of: (a) receipt; (b) delivery to the proper
address or telephone number of the director as shown in the Corporation's
records; or (c) three days after its deposit in the United States mail, as
evidenced by the postmark, if correctly addressed and mailed with first-class
postage prepaid.

               2.9.3 Notice of any meeting of the Board of Directors may be
waived by any director at any time, by a signed writing delivered to the
Corporation or, if the Corporation has designated an address, location, or
system to which waiver may be electronically transmitted and the waiver is
electronically transmitted to the designated address, location, or system, by an
executed electronically transmitted record, and such waiver shall be included in
the minutes, either before or after the meeting. Attendance or participation by
a director at a meeting shall constitute a waiver of any required notice of the
meeting unless the director promptly objects to holding the meeting or to the
transaction of any business on the grounds that the meeting was not


                                       7



lawfully convened and the director does not thereafter vote for or assent to
action taken at the meeting.

          2.10 Directors' Action Without A Meeting. The Board of Directors or a
committee thereof may take any action without a meeting that it could properly
take at a meeting if one or more consents setting forth the action are executed
by all of the directors, or all of the members of the committee, as the case may
be, either before or after the action is taken, and if the consents are
delivered to the Corporation for inclusion in the minutes or filing with the
corporate records. Consents shall be set forth either (a) in an executed record
or (b) if the Corporation has designated an address, location, or system to
which the consent may be electronically transmitted and the consent is
electronically transmitted to the designated address, location, or system, in an
executed electronically transmitted record. Such action shall be effective when
the last director executes the consent, unless the consent specifies a later
effective date.

          2.11 Committees of the Board of Directors. The Board of Directors, by
resolutions adopted by a majority of the members of the Board of Directors in
office, may create from among its members one or more committees and shall
appoint the members thereof. Each such committee must have two or more members,
who shall be directors and who shall serve at the pleasure of the Board of
Directors. Each committee of the Board of Directors may exercise the authority
of the Board of Directors to the extent provided in its enabling resolution and
any pertinent subsequent resolutions adopted in like manner, provided that the
authority of each such committee shall be subject to applicable law. Each
committee of the Board of Directors shall keep regular minutes of its
proceedings and shall report to the Board of Directors when requested to do so.

          2.12 Telephone Meetings. Members of the Board of Directors or of any
committee appointed by the Board of Directors may participate in a meeting of
the Board of Directors or committee by means of a conference telephone or
similar communications equipment that enables all persons participating in the
meeting to hear each other during the meeting. Participation by such means shall
constitute presence in person at a meeting.

          2.13 Chairman. The Board may elect from among its members a Chairman
of the Board who shall have such duties as the Board of Directors may from time
to time prescribe but shall not be an officer of the Corporation.

          2.14 Compensation of Directors. The Board of Directors may fix the
compensation of directors as such and may authorize the reimbursement of their
expenses.

                                    SECTION 3

of Directors. Unless otherwise restricted by the Board of Directors, the

Directors may from time to time designate.

               3.3.2 Chief Scientist. The Chief Scientist, if one is appointed

or President may from time to time designate.

               3.3.3 Vice President. Each Vice President shall perform such
duties as the Board of Directors may from time to time designate. In addition,
in the absence or disability of the President, the Vice President (or if there

filled by the Board of Directors at any regular or special meeting.

          3.5 Removal. Any officer or agent may be removed by action of the
Board of Directors with or without cause, but any removal shall be without
prejudice to the contract rights, if any, of the person removed. Election or
appointment of an officer or agent shall not of itself create any contract
rights.

          3.6 Compensation. The compensation of all officers of the Corporation
shall be fixed by the Board of Directors.

                                    SECTION 4

                                     SHARES

          4.1 Certificated and Uncertificated Shares. The Board of Directors may
authorize the issue of some or all of the shares of any or all classes or series
of stock of the Corporation without certificates. Any such authorization does
not affect shares already represented by certificates until they are surrendered
to the Corporation. As to any shares of stock that are represented by
certificates, such certificates shall be issued in numerical order, and each
certificate shall be signed by two officers of the Corporation, including the
President, the Chief Scientist, any Vice President, the Secretary and the
Treasurer. Share certificates may be sealed with the corporate seal, if any.
Facsimiles of the signatures and seal may be used as permitted by law. Every
share certificate shall state:

          (a)  the name of the Corporation;

          (b)  that the Corporation is organized under the laws of the State of
               Washington;

          (c)  the name of the person to whom the share certificate is issued;

          (d)  the number, class and series (if any) of shares that the
               certificate represents; and

          (e)  if the Corporation is authorized to issue shares of more than one
               class or series, that upon written request and without charge,
               the Corporation will furnish any shareholder with a full
               statement of


                                       10



               the designations, preferences, limitations and relative rights of
               the shares of each class or series, and the authority of the
               Board of Directors to determine variations for future series.

          4.2 Consideration for Shares. Shares of the Corporation may be issued
for such consideration as shall be determined by the Board of Directors to be
adequate. The consideration for the issuance of shares may be paid in whole or
in part in cash, or in any tangible or intangible property or benefit to the
Corporation, including but not limited to promissory notes, services performed,
contracts for services to be performed, or other securities of the Corporation.
Establishment by the Board of Directors of the amount of consideration received
or to be received for shares of the Corporation shall be deemed to be a
determination that the consideration so established is adequate.

          4.3 Transfers. Shares not represented by certificates may be
transferred on the stock transfer records of the Corporation upon proper
instruction from the registered holder or other appropriate person with respect
to such shares in accordance with applicable law, including without limitation
Article 8 of the Washington Uniform Commercial Code. Shares that are represented
by certificates may be transferred on the stock records of the Corporation by
delivery of the certificate, accompanied either by an assignment in writing on
the back of the certificate, or by a written power of attorney to sell, assign
and transfer the same, signed by the record holder of the certificate. Except as
otherwise specifically provided in these Bylaws, no shares of stock that are
represented by certificates shall be transferred on the books of the Corporation
until the outstanding certificate therefore has been surrendered to the
Corporation.

          4.4 Loss or Destruction of Certificates. In the event of the loss or
destruction of any certificate, a new certificate may be issued in lieu thereof
upon satisfactory proof of such loss or destruction, and upon the giving of
security against loss to the Corporation by bond, indemnity or otherwise, to the
extent deemed necessary by the Board of Directors, the Secretary, or the
Treasurer.

          4.5 Fixing Record Date. The Board of Directors may fix in advance a
date as the record date for determining shareholders entitled: (a) to notice of
or to vote at any shareholders' meeting or any adjournment thereof; (b) to
receive payment of any share dividend; or (c) to receive payment of any
distribution. The Board of Directors may in addition fix record dates with
respect to any allotment of rights or conversion or exchange of any securities
by their terms, or for any other proper purpose, as determined by the Board of
Directors and by law. The record date shall be not more than 70 days and, in
case of a meeting of shareholders, not less than 10 days (or such longer period
as may be required by Washington law) prior to the date on which the particular
action requiring determination of shareholders is to be taken. If no record date
is fixed for determining the shareholders entitled to notice of or to vote at a
meeting of shareholders, the record date shall be the date before the day on
which notice of the meeting is delivered. If no record date is fixed for the
determination of shareholders entitled to a distribution (other than one
involving a purchase, redemption, or other acquisition of the Corporation's own
shares), the record date shall be the date on which the Board adopted the
resolution declaring the distribution.


                                       11



If no record date is fixed for determining shareholders entitled to a share
dividend, the record date shall be the date on which the Board of Directors
authorized the dividend.

person or by his or her attorney or agent, the corporate records referred to in
subsection 5.1.2 hereof if the shareholder gives the Corporation written notice
of the demand at least five business days before the date on which the
shareholder wishes to make such inspection.

               5.3.2 In addition, if a shareholder's demand is made in good
faith and for a proper purpose, a shareholder may inspect and copy, during
regular business hours at a reasonable location specified by the Corporation,
excerpts from minutes of any meeting of the Board of Directors, records of any
action of a committee of the Board of Directors, minutes of any meeting of the
shareholders, and records of actions taken by the shareholders or the Board of
Directors without a meeting, to the extent not subject to inspection under
subsection 5.3.1,


                                       12



accounting records of the Corporation, or the record of shareholders; provided
that the shareholder shall have made a demand describing with reasonable
particularity the shareholder's purpose and the records the shareholder desires
to inspect, and provided further that the records are directly connected to the
shareholder's purpose.

               5.3.3 This section shall not affect any right of shareholders to
inspect records of the Corporation that may be otherwise granted to the
shareholders by law.

                       MISCELLANEOUS PROCEDURAL PROVISIONS

          The Board of Directors may adopt rules of procedure to govern any
meetings of shareholders or directors to the extent not inconsistent with law,
the Corporation's Restated Articles of Incorporation, or these Bylaws, as they
are in effect from time to time. In the absence of any rules of procedure
adopted by the Board of Directors, the chairman of the meeting shall make all
decisions regarding the procedures for any meeting.

                                    SECTION 9

                               AMENDMENT OF BYLAWS

          The Board of Directors is expressly authorized to adopt, amend and
repeal the Bylaws of the Corporation subject to approval by a majority of the
Continuing Directors (as defined below); provided, however, the Board of
Directors may not repeal or amend any bylaw that the shareholders have expressly
provided may not be amended or repealed by the Board of Directors.


                                       13



The shareholders of the Corporation also have the power to adopt, amend or
repeal the Bylaws of the Corporation by the affirmative vote of the holders of

                                   SECTION 10

                     INDEMNIFICATION OF DIRECTORS AND OTHERS

          10.1 Grant of Indemnification. Subject to section 10.2, each person
who was or is made a party or is threatened to be made a party to or is involved
(including, without limitation, as a witness) in any threatened, pending, or
completed action, suit or proceeding, whether formal or informal, civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she is or was a director of the Corporation or
who, while a director of the Corporation, is or was serving at the request of
the Corporation as a director, officer, employee or agent of this or another
corporation or of a partnership, joint venture, trust, other enterprise, or
employee benefit plan, whether the basis of such proceeding is alleged action in
an official capacity as a director or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent permitted by applicable law, as then in
effect, against all expense, liability and loss (including attorneys' fees,
costs, judgments, fines, ERISA excise taxes or penalties and amounts to be paid
in settlement) reasonably incurred or suffered by such person in connection
therewith, and such indemnification shall continue as to a person who has ceased
to be a director and shall inure to the benefit of his or her heirs, executors
and administrators.

          10.2 Limitations on Indemnification. Notwithstanding section 10.1, no
indemnification shall be provided hereunder to any such person to the extent
that such indemnification would be prohibited by the Washington Business
Corporation Act or other applicable law as then in effect, nor, except as
provided in section 10.4 with respect to proceedings seeking to enforce rights
to indemnification, shall the Corporation indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person except where such proceeding (or part thereof) was authorized by the
Board of Directors of the Corporation.

          10.3 Advancement of Expenses. The right to indemnification conferred
in this section shall include the right to be paid by the Corporation the
expenses incurred in defending any such proceeding in advance of its final
disposition, except where the Board of Directors shall have adopted a resolution
expressly disapproving such advancement of expenses.

          10.4 Right to Enforce Indemnification. If a claim under section 10.1
is not paid in full by the Corporation within 60 days after a written claim has
been received by the Corporation, or if a claim for expenses incurred in
defending a proceeding in advance of its final disposition authorized under
section 10.3 is not paid within 60 days after a written claim has been received
by the Corporation, 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. The claimant shall be presumed to be
entitled to indemnification hereunder 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 required undertaking
has been tendered to the Corporation), and thereafter the Corporation shall have
the burden of proof to overcome the


                                       15



presumption that the claimant is so entitled. It shall be a defense to any such
action (other than an action with respect to expenses authorized under section
10.3) that the claimant has not met the standards of conduct which make it
permissible hereunder or under the Washington Business Corporation Act for the
Corporation to indemnify the claimant for the amount claimed, but the burden of
proving such defense shall be on the Corporation.

          10.5 Alternate Procedures. Pursuant to RCW 23B.08.560(2) or any
successor provision of the Washington Business Corporation Act, the procedures
for indemnification and advancement of expenses set forth in this section are in
lieu of the procedures required by RCW 23B.08.550 or any successor provision of
the Washington Business Corporation Act.

          10.6 Nonexclusivity. The right to indemnification and the advancement
of expenses conferred in this section shall not be exclusive of any other right
which any person may have or hereafter acquire under any statute, provision of
the Restated Articles of Incorporation or the Bylaws of the Corporation, general
or specific action of the Board, contract or otherwise.

          10.7 Indemnification of Officers, Employees and Agents. The
Corporation, by action of its Board of Directors from time to time, may provide
indemnification and pay expenses in advance of the final disposition of a
proceeding to officers, employees and agents of the Corporation on the same
terms and with the same scope and effect as the provisions of this section with
respect to the indemnification and advancement of expenses of directors of the
Corporation or pursuant to rights granted pursuant to, or provided by, the
Washington Business Corporation Act or on such other terms as the Board may deem
proper.

          10.8 Insurance and Other Security. The Corporation may maintain
insurance, at its expense, to protect itself and any individual who is or was a
director, officer, employee or agent of the Corporation or another Corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against or incurred by the individual in that capacity or arising from
his or her status as an officer, director, agent, or employee, whether or not
the Corporation would have the power to indemnify such person against the same
liability under the Washington Business Corporation Act. The Corporation may
enter into contracts with any director or officer of the Corporation in
furtherance of the provisions of this section and may create a trust fund, grant
a security interest 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 section.

          10.9 Amendment or Modification. This section may be altered or amended
at any time as provided in these Bylaws, but no such amendment shall have the
effect of diminishing the rights of any person who is or was an officer or
director as to any acts or omissions taken or omitted to be taken prior to the
effective date of such amendment.

          10.10 Effect of Section. The rights conferred by this section shall be
deemed to be contract rights between the Corporation and each person who is or
was a director or officer. The Corporation expressly intends each such person to
rely on the rights conferred hereby in performing his or her respective duties
on behalf of the Corporation.
