Dear Shareholder:

     You are cordially invited to attend a Special Meeting of Shareholders of
InterWest Bancorp, Inc. ("InterWest"), the holding company for InterWest
Savings Bank ("InterWest Savings"), to be held at _____________________, Oak
Harbor, Washington on_____________, 1996 at____________ _.m., local time. 

     The attached Notice of Special Meeting of Shareholders and
Prospectus/Joint Proxy Statement describe the formal business to be transacted
at the meeting.  The primary purpose of the meeting is to consider and vote
upon a proposal to approve the Agreement and Plan of Mergers (the "Merger
Agreement") dated as of January 10, 1996 between InterWest and InterWest
Savings, and Central Bancorporation ("Central") and its subsidiaries, Central
Washington Bank and North Central Washington Bank (together, the "Banks"). 
The Merger Agreement provides that Central will be merged with and into
InterWest, with InterWest surviving the merger.  Directors and officers of
InterWest, as well as representatives of Ernst & Young LLP, InterWest's
independent auditors, will be present to respond to any appropriate questions
shareholders may have. 

    The Merger Agreement provides that upon consummation of the merger all
outstanding shares of common stock of Central will be converted into shares of
common stock of InterWest.  You are urged to review carefully the enclosed
Prospectus/Joint Proxy Statement, which contains a more complete description
of the terms of the merger.

     The Board of Directors of InterWest has unanimously approved the Merger
Agreement and recommends that the shareholders vote FOR the approval of the
Merger Agreement.  InterWest's financial advisor, Sandler O'Neill & Partners,
L.P.,  has issued its opinion to the effect that, as of the date hereof and
based on the factors and assumptions described therein, the consideration to
be paid by InterWest pursuant to the Merger Agreement is fair to InterWest
from a financial point of view.  Approval of the Merger Agreement requires the
affirmative vote of a majority of the outstanding shares of InterWest common
stock.

     It is very important that your shares be represented at the Special
Meeting, regardless of whether you plan to attend in person.  A failure to
vote, either by not returning the enclosed proxy or by checking the "Abstain"
box thereon, will have the same effect as a vote against approval of the
Merger Agreement.  To assure that your shares are represented in voting on
this very important matter, please sign, date and return the enclosed proxy
card in the enclosed postage-prepaid envelope whether or not you plan to
attend the meeting.  If you do attend, you may, if you wish, revoke your proxy
and vote your shares in person at the meeting. 

     The merger is an important step for InterWest and its shareholders.  On
behalf of the Board of Directors, we recommend that you vote FOR approval of
the Merger Agreement.  

                         Sincerely,

Dear Shareholder:

     You are cordially invited to attend the Annual Meeting of Shareholders of
Central Bancorporation ("Central"), the holding company for Central Washington
Bank and North Central Washington Bank (together, the "Banks") to be held at
301 North Chelan, Wenatchee, Washington on_______________, 1996 at _______.m.,
local time.

     The attached Notice of Annual Meeting of Shareholders and
Prospectus/Joint Proxy Statement describe the formal business to be transacted
at the meeting.  At the Annual Meeting, in addition to the election of
directors, shareholders will be asked to consider and vote upon a proposal to
approve the Agreement and Plan of Mergers (the "Merger Agreement") dated as of
January 10, 1996 between InterWest Bancorp, Inc. ("InterWest") and InterWest
Savings Bank ("InterWest Savings"), and Central and the Banks.  The Merger
Agreement provides that Central will be merged with and into InterWest, with
InterWest surviving the merger.

     Upon consummation of the merger, each outstanding share of Central common
stock (excluding any dissenting shares and certain shares held by InterWest
and Central) will be converted into the right to receive a number of shares of
InterWest common stock pursuant to a formula, as follows:  (a) 1.7 shares if
the "InterWest Price" is $20.00 or less; (b) the result obtained by dividing
$34.00 by the InterWest Price if the InterWest Price is greater than $20.00
and less than $24.12; or (c) 1.41 shares of InterWest common stock if the
InterWest Price is $24.12 or greater, in a transaction that is generally
tax-free for federal income tax purposes, all as more fully discussed in the
accompanying Prospectus/Joint Proxy Statement.  For purposes of the above
formula, the "InterWest Price" will be the average of the bid and ask prices
per share of all market makers, as reported on Bloomberg Financial Markets, of
InterWest common stock on the Nasdaq Stock Market reporting system for the ten
trading days beginning on and including the twentieth trading day immediately
preceding the effective date of the merger.  The last reported sale price of
InterWest common stock on the Nasdaq National Market ("IWBK") on __________,
1996 was $___ per share.

     You are urged to review carefully the enclosed Prospectus/Joint Proxy
Statement, which contains a more complete description of the terms of the
merger.

     The Board of Directors of Central has unanimously approved the Merger
Agreement and recommends that the shareholders vote FOR the approval of the
Merger Agreement.  Central's financial advisor, Columbia Financial Advisors,
Inc., has issued its opinion to the effect that, as of the date hereof and
based on the factors and assumptions described therein, the consideration to
be paid by InterWest pursuant to the Merger Agreement is fair to shareholders
of Central from a financial point of view.  Approval of the Merger Agreement
requires the affirmative vote of two-thirds of the outstanding shares of
Central common stock.


     You will also be asked at the meeting to vote for the election of two
directors to serve for a three year term or until such time as the merger is
effective.  The Central Board of Directors recommends that shareholders vote
FOR the proposed slate of directors named in the enclosed Prospectus/Joint
Proxy Statement.

     It is very important that your shares be represented at the Annual
Meeting, regardless of whether you plan to attend in person.  A failure to
vote, either by not returning the enclosed proxy or by checking the "Abstain"
box thereon, will have the same effect as a vote against approval of the
Merger Agreement.  To assure that your shares are represented in voting on
this very important matter, please sign, date and return the enclosed proxy
card in the enclosed postage-prepaid envelope whether or not you plan to
attend the meeting.  If you do attend, you may, if you wish, revoke your proxy
and vote your shares in person at the meeting.

     On behalf of the Board of Directors, I recommend that you vote FOR
approval of the Merger Agreement.

                                Sincerely,

                                /s/ Gary M. Bolyard

THE MERGERS; EXCHANGE RATIO 

     The Merger Agreement provides for the merger of Central with and into
InterWest, with InterWest to be the surviving corporation in the Merger, and
immediately thereafter for the merger of the Banks with and into InterWest
Savings, with InterWest Savings to be the surviving institution (the "Bank
Merger").  As a result of the Merger and the Bank Merger, Central and the
Banks will cease to exist, and InterWest and InterWest Savings will succeed to
all of the assets and liabilities of Central and the Banks, respectively.  See
"THE MERGER -- General; Exchange Ratio."

     Upon consummation of the Merger, each outstanding share of Central Common
Stock (excluding any shares held by shareholders who perfect their dissenters'
rights of appraisal ("Dissenting Shares") and any shares of stock held by
InterWest or Central, other than in a fiduciary capacity or in satisfaction of
a debt previously contracted (together with the Dissenting Shares, "Excluded
Shares") will be automatically converted into the right to receive a number of
shares of InterWest Common Stock, as follows: (i) 1.7 shares of InterWest
Common Stock if the "InterWest Price" is $20.00 or less; (ii) the number of
shares obtained by dividing $34.00 by the InterWest Price if the InterWest
Price is greater than $20.00 and less than $24.12, or (iii) 1.41 shares of
InterWest Common Stock if the InterWest Price is $24.12 or greater (the
"Exchange Ratio").  The "InterWest Price" is defined in the Merger Agreement
to mean the average of the bid and ask prices per share of all market makers,
as reported on Bloomberg Financial Markets, of InterWest Common Stock on the
Nasdaq Stock Market reporting system for the ten trading days beginning on and
including the twentieth trading day immediately preceding the Effective Date. 
Each holder of Central Common Stock who would otherwise be entitled to a
fractional share of InterWest Common Stock will receive cash in lieu thereof
determined by multiplying such fraction by the InterWest Price.  If a
"Triggering Event" relating to certain business combinations between InterWest
and a third party shall have occurred, the Exchange Ratio will be based on a
ten trading day period prior to the Triggering Event.  InterWest has no plans,
arrangements or understandings, written or oral, regarding any business
combination with a third party.  Upon completion of the Merger, shareholders
of Central will no longer own any stock in Central.

     Central shareholders should note that the market price of the InterWest
Common Stock they receive will continue to be subject to changes in market
value and may, therefore, have a market value as of the date they receive
certificates for their shares (or such shares are otherwise made available to
them) that is less than, or greater than, the value of such stock at the date
of such determination.  For a more detailed discussion of the calculation of
the number of shares of InterWest Common Stock to be received in exchange for
Central Common Stock, see "THE MERGER -- General; Exchange Ratio."

agreed to appoint Mr. Bolyard to the Executive Committees and to appoint Mr.
Carlson to the Audit Committees of the Boards of Directors of InterWest and
InterWest Savings.

EFFECTIVE DATE OF THE MERGER 

     Unless the parties agree upon another date, the "Effective Date" of the
Merger will be the date ten business days after the fulfillment or waiver of
each of the conditions to the obligations of the parties to effect the Merger
and the granting of all regulatory approvals.  Either InterWest or Central may
terminate the Merger Agreement if the Effective Date does not occur on or
before September 30, 1996.

CONDITIONS TO CONSUMMATION OF THE MERGER

     Consummation of the Merger is subject to, among other things: (i)
approval of the Merger Agreement by the holders of not less than two-thirds of
the outstanding shares of Central Common Stock and by the holders of not less
than a majority of the outstanding shares of InterWest Common Stock; (ii)
receipt of all applicable regulatory approvals without any condition that, in
the opinion of InterWest, would deprive InterWest of the material economic or
business benefits of the Merger; (iii) receipt by InterWest and Central of the
opinion of Breyer & Aguggia, dated as of the Effective Date, as to certain
federal income tax consequences of the Merger; (iv) the InterWest Common Stock
to be issued to Central shareholders having been approved for listing on the
Nasdaq National Market; (v) Gary M. Bolyard and Joseph E. Riordan having
entered into employment agreements with InterWest and InterWest Savings; (vi)
the receipt by InterWest of a letter from Central's independent certified
public accountants, dated as of or shortly prior to the Effective Date, with
respect to Central's financial position and results of operations; (vii)
receipt by InterWest of an agreement from each "affiliate" of Central
restricting the sale of InterWest Common Stock received by such affiliate in
the Merger; (viii) the number of Dissenting Shares does not exceed 10% of the
outstanding shares of Central Common Stock; and (ix) receipt by InterWest and
Central of letters from their respective certified public accountants to the
effect that the Merger will qualify for pooling of interests accounting
treatment.  The obligations of Central are subject to the further condition
that if the InterWest Price is less than $17.00, Central may elect to
terminate the Merger Agreement unless InterWest elects to adjust the Exchange
Ratio so that each share of Central Common Stock is converted into $28.90 of
InterWest Common Stock, based on the InterWest Price.  See "THE MERGER --
Conditions to Consummation of the Merger." 

STOCK OPTION AGREEMENT
     
     As a condition to InterWest's willingness to enter into the Merger
Agreement and in consideration thereof, Central entered into a Stock Option
Agreement with InterWest, dated as of January 10, 1996 (the "Stock Option
Agreement").  The Stock Option Agreement is set forth as Appendix B to this
Prospectus/Joint Proxy Statement.  Pursuant to the Stock Option Agreement,
Central granted to InterWest an irrevocable option (the "Option"), exercisable
only under certain limited and specifically defined circumstances, none of
which, to the best of InterWest's and Central's knowledge, has occurred as of
the date hereof, to purchase up to 201,898 authorized but unissued shares of
Central Common Stock for a purchase price of $26.00 per share, subject to
adjustment in certain circumstances.  The number of shares of Central Common
Stock subject to the Option represents approximately 19.9% of the outstanding
shares of Central Common Stock as of the Central Record Date, before giving
effect to the issuance of such shares.  InterWest does not have any voting
rights with respect to the shares of Central Common Stock subject to the
Option prior to exercise of the Option.  
     
     The Stock Option Agreement and the Option are intended to make it more
difficult for another party to acquire Central, thereby increasing the
likelihood that the Merger will occur.  See "The MERGER -- Stock Option
Agreement." 
<PAGE>
ACCOUNTING TREATMENT
     
     It is anticipated that the Merger will be accounted for as a pooling of
interests by InterWest under generally accepted accounting principles.  The
Merger agreement provides that a condition to InterWest's obligation to
consummate the Merger is the receipt by InterWest of a letter from Ernst &
Young LLP, InterWest's independent auditors, and the receipt by Central of a
letter from Deloitte & Touche LLP, Central's independent auditors, to the
effect that such firms concur with the respective management's conclusions as
to the appropriateness of pooling of interests accounting for the Merger.  See
"THE MERGER -- Conditions to Consummation of the Merger" and "-- Accounting
Treatment."  

REGULATORY REQUIREMENTS

     The Merger and the Bank Merger are subject to the receipt of certain
prior approvals from the Board of Governors of the Federal Reserve System
("Federal Reserve Board"), the FDIC and the Department.  Based on the filing
of an application for approval of the Bank Merger with the FDIC, the Federal
Reserve Board has waived the filing of an application for approval of the
Merger.  An application for approval of the Bank Merger was filed with the
FDIC and the Department on  _______, 1996.  There can be no assurance that
such approval will be obtained, and, if obtained, that it will not impose
conditions that, in the opinion of InterWest, would deprive InterWest of the
economic and business benefits of the Merger so as to render it inadvisable in
the judgment of InterWest to proceed with the Merger.  See "THE MERGER --
Regulatory Requirements."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     Consummation of the Merger is conditioned, among other things, on receipt
by InterWest and Central of an opinion of Breyer & Aguggia, special counsel
for InterWest to the effect that no gain or loss will be recognized for
federal income tax purposes by stockholders of Central who receive InterWest
Common Stock in exchange for their shares of Central Common Stock, other than
with respect to cash received in lieu of fractional share interests.  See "THE
MERGER -- Certain Federal Income Tax Consequences."  
     
     All Central shareholders are urged to consult their own tax advisors as
to the specific tax consequences to them of the Merger, including the
applicability and effect of federal, state, local, foreign and other tax laws. 

DISSENTERS' RIGHTS

     Central shareholders have the right to dissent from the Merger and obtain
payment of the fair value of their shares of Central Common Stock under the
provisions of Chapter 13 of the Washington Business Corporation Act ("WBCA"). 
A shareholder's failure to follow exactly the procedures specified in Chapter
13 of the WBCA will result in loss of such shareholder's dissenters' rights. 
Accordingly Central shareholders wishing to dissent from the Merger are urged
to read carefully "THE MERGER -- Dissenters' Rights" and the copy of Chapter
13 of the WBCA set forth in Appendix E to this Prospectus/Joint Proxy
Statement, and to consult with their own legal advisors.  If Central
shareholders perfect dissenters' rights with respect to more than 10% of the
outstanding shares of Central Common Stock, InterWest may elect not to
consummate the Merger.  See "THE MERGER -- Conditions to Consummation of the
Merger."  Additionally, if shareholders perfect dissenters' rights with
respect to more than 10% of the outstanding shares of Central Common Stock and
InterWest elects to consummate the Merger, the Merger will not qualify for
pooling of interests accounting treatment.  See "THE MERGER -- Accounting
Treatment." 

COMPARISON OF SHAREHOLDERS' RIGHTS

     Shareholders of Central who receive shares of InterWest Common Stock in
exchange for their shares of Central Common Stock will be governed, with
respect to their rights as such shareholders, by InterWest's Articles of
Incorporation and Bylaws.  For a discussion of certain material differences in
the rights of shareholders of 
<PAGE>
InterWest and Central and an explanation of certain possible antitakeover
effects of certain provisions in InterWest's Articles of Incorporation and
Bylaws, see "COMPARISON OF SHAREHOLDERS' RIGHTS."


SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA 

     The following tables set forth selected historical consolidated financial
data for InterWest and Central and selected unaudited pro forma combined
financial data, giving effect to the Merger using the pooling of interests
method of accounting.  For pro forma purposes, InterWest's consolidated
statements of operations for the five fiscal years ended September 30, 1995,
1994, 1993, 1992 and 1991 and for the three months ended December 31, 1995 and
1994 have been combined with the consolidated statements of operation of
Central for the five fiscal years ended December 31, 1995, 1994, 1993, 1992
and 1991 and for the three months ended December 31, 1995 and 1994.  For pro
forma purposes, InterWest's consolidated statement of condition as of December
31, 1995, has been combined with Central's consolidated statement of condition
as of December 31, 1995.  This information should be read in conjunction with
the historical financial statements of InterWest and Central, including the
respective notes thereto, the unaudited pro forma financial information
appearing elsewhere in this Prospectus/Joint Proxy Statement, including the
notes thereto, and the other documents incorporated by reference herein.  See
"AVAILABLE INFORMATION," "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE," 
"PRO FORMA FINANCIAL INFORMATION" and the Central 1995 10-KSB accompanying
this Prospectus/Joint Proxy Statement. 

     The InterWest historical consolidated financial statement data as of and
for the three months ended December 31, 1995 have been prepared on the same
basis as the historical information derived from audited financial statements,
and in the opinion of management, contain all adjustments, consisting only of
normal recurring accruals, necessary for the fair presentation of results of
operations for such periods.

     The 1.7 Exchange Ratio used in the pro forma information is based on the
average of the last reported bid and ask price on the Nasdaq National Market
of InterWest Common Stock on ______, 1996, which was $___ per share.  The
actual Exchange Ratio will depend on the InterWest Price (which will not be
known until shortly before the Effective Date) and may be higher or lower than
1.7.  The pro forma information would be different if the InterWest Price
results in an Exchange Ratio different from 1.7.  Central shareholders are
urged to obtain current quotations of the market price of InterWest Common
Stock.  The selected pro forma combined financial data is unaudited.  Such
data is intended for illustrative purposes only and is not necessarily
indicative of future results of operations or the future financial position of
the combined company or of the results of operations and financial position of
the combined company that would have actually occurred had the Merger been in
effect as of the dates or for the periods presented.

                             THE MEETINGS

InterWest Special Meeting

     Place, Time and Date.  The InterWest Special Meeting will be held on
__________, _____________, 1996 at ___:00  a.m., local time, at
______________, Oak Harbor, Washington.  This Prospectus/Joint Proxy Statement
is being sent to holders of InterWest Common Stock and is accompanied by a
form of proxy that is being solicited by the InterWest Board for use at the
InterWest Special Meeting and any adjournments or postponements thereof. 

     Purpose.  The purpose of the InterWest Special Meeting is (i) to consider
and vote upon a proposal to approve the Merger Agreement described herein,
providing for, among other things, the merger of Central with and into
InterWest, with InterWest surviving the Merger, and the issuance of shares of
InterWest Common Stock to the shareholders of Central and (ii) to act upon
such other matters, if any, as may properly come before the Special Meeting. 

     Record Date; Shares Entitled to Vote.  The InterWest Board has fixed the
close of business on _________, 1996 as the InterWest Record Date for
determining shareholders entitled to notice of and to vote at the InterWest
Special Meeting.  Only those holders of InterWest Common Stock of record on
the InterWest Record Date will be entitled to notice of and to vote at the
InterWest Special Meeting.  Each share of InterWest Common Stock will be
entitled to one vote.  At the InterWest Record Date, there were _____________
shares of InterWest Common Stock outstanding and entitled to be voted at the
InterWest Special Meeting.

     Vote Required.  A majority of the shares entitled to vote, represented in
person or by proxy, will constitute a quorum of InterWest shareholders at the
Special Meeting.  Abstentions and broker non-votes (i.e., proxies from brokers
or nominees indicating that such person has not received instructions from the
beneficial owners or other persons entitled to vote shares as to a matter with
respect to which the brokers or nominees do not have  discretionary power to
vote) will be considered present for purposes of determining whether a quorum
exists.  Approval of the Merger Agreement requires the affirmative vote of the
holders of a majority of the outstanding shares of InterWest Common Stock. 
Abstentions and broker non-votes will have the same effect as votes cast
against approval of the Reorganization Agreement.

     At the InterWest Record Date, the directors and executive officers of
InterWest and their affiliates beneficially owned an aggregate of __________
shares of InterWest Common Stock, which represents ___% of the shares entitled
to be voted at the InterWest Special Meeting.  

     Proxies.   Holders of InterWest Common Stock may vote either in person or
by properly executed proxy.  Shares of InterWest Common Stock represented by a
properly executed proxy received prior to or at the InterWest Special Meeting
will, unless such proxy is revoked, be voted in accordance with the
instructions indicated on such proxy.  If no instructions are indicated on a
properly executed proxy, the shares covered thereby will be voted FOR the
proposal to approve the Merger Agreement.  Failure to return the proxy card or
to vote in person at the InterWest Special Meeting will have the effect of a
vote cast against the Merger Agreement.  If any other matters are properly
presented at the InterWest Special Meeting for consideration, including, among
other things, a motion to adjourn the InterWest Special Meeting to another
time and/or place (including, without limitation, for the purpose of
soliciting additional proxies), the persons named in the proxy and acting
thereunder will have discretion to vote on such matters in accordance with
their best judgment; provided, however, that no proxy which is voted against
the proposal to approve the Merger Agreement will be voted in favor of any
such adjournment or postponement.  As of the date hereof, the InterWest Board
knows of no such other matters.

     Any proxy given pursuant to this solicitation or otherwise may be revoked
by the person giving it at any time before it is voted by delivering to the
Secretary of InterWest, on or before the taking of the vote at the InterWest
Special Meeting, a written notice of revocation bearing a later date than the
proxy or a later dated proxy
<PAGE>
relating to the same shares of InterWest Common Stock, or by attending the
InterWest Special Meeting and voting in person.  Attendance at the InterWest
Special Meeting will not in itself constitute revocation of a proxy.

     The proxy for the InterWest Special Meeting is being solicited on behalf
of the InterWest Board.  The expense of soliciting proxies for the InterWest
Special Meeting will be borne by InterWest.  The expense of printing this
Prospectus/Joint Proxy Statement is to be shared equally by InterWest and
Central.  All other costs and expenses incurred in connection with the
Reorganization Agreement and the transactions contemplated thereby are to be
paid by the party incurring such expenses.  Proxies will be solicited
principally by mail, but may also be solicited by the directors, officers and
other employees of InterWest in person or by telephone, facsimile or other
means of communication.  Such directors, officers and employees will receive
no compensation therefor in addition to their regular compensation, but may be
reimbursed for out-of-pocket expenses in connection with such solicitation. 
Brokers and others who hold InterWest Common Stock on behalf of another will
be asked to forward proxy material and related documents to the beneficial
owners of such stock, and InterWest will reimburse them for their expenses in
doing so.  In addition, InterWest has engaged _____________ to solicit proxies
for the Special Meeting.  _____________ will receive an estimated fee of
$_____ plus reasonable out-of-pocket expenses.  InterWest has agreed to
indemnify _____________ against certain liabilities that may be incurred by
____________ arising out of the services provided to InterWest in connection
with the Special Meeting.

Approval of the Merger Agreement requires the affirmative vote of the holders
of two- thirds of the shares of Central Common Stock entitled to vote at the

effect as votes cast against approval of the Reorganization Agreement.  A
plurality of the votes cast at the Central Annual Meeting by the holders of
shares of Central Common Stock entitled to vote is required for the election
of persons nominated to serve as directors.  Any shares not voted will have no
effect on the election of directors provided that a quorum for the transaction

her shares for approval of the Merger Agreement.   

     Proxies.  Holders of Central Common Stock may vote either in person or by
properly executed proxy.  Shares of Central Common Stock represented by a
properly executed proxy received prior to or at the Central Annual Meeting
will, unless such proxy is revoked, be voted in accordance with the
instructions indicated on such proxy.  If no instructions are indicated on a
properly executed proxy, the shares covered thereby will be voted FOR the
proposal to approve the Merger Agreement.  Failure to return the proxy card or

cast against the Merger Agreement.  If any other matters are properly
presented at the Central Annual Meeting for consideration, including, among

and/or place (including, without limitation, for the purpose of soliciting

judgment; provided, however, that no proxy which is voted against the proposal
to approve the Merger Agreement will be voted in favor of any such adjournment
or postponement.  As of the date hereof, the Central Board knows of no such
other matters.   

     Any proxy given pursuant to this solicitation or otherwise may be revoked
by the person giving it at any time before it is voted by delivering to the
Secretary of Central, on or before the taking of the vote at the Central
Annual Meeting, a written notice of revocation bearing a later date than the
proxy or a later dated proxy relating to the same shares of Central Common
Stock, or by attending the Central Annual Meeting and voting in person. 
Attendance at the Central Annual Meeting will not in itself constitute a
revocation of a proxy.

Meeting will be borne by Central.  The expense of printing this
Prospectus/Joint Proxy Statement is to be shared equally by Central and

                           THE MERGER

     The descriptions in this Prospectus/Joint Proxy Statement of the terms
and conditions of the Merger and related transactions are qualified in their
entirety by reference to the Merger Agreement, a copy of which is attached as
Appendix A to this Prospectus/Joint Proxy Statement and is incorporated herein
by reference.

GENERAL; EXCHANGE RATIO

     The Merger Agreement provides for the merger of Central with and into
InterWest, with InterWest surviving the Merger. It is further intended that
immediately thereafter the Banks will be merged with and into InterWest
Savings, with InterWest Savings surviving the merger.   The separate existence
of Central and the Banks will cease upon completion of the respective mergers. 
While InterWest and Central believe that they will receive the requisite
regulatory approvals for the Merger, there can be no assurance that such
approvals will be received or, if received, as to the timing of such approvals
or as to the ability to obtain such approvals on satisfactory terms. See "--
Conditions to Consummation of the Merger" and "-- Regulatory Requirements."

     Upon consummation of the Merger, each outstanding share of Central Common
Stock (excluding any Excluded Shares) will be automatically converted into the
right to receive a number of shares of InterWest Common Stock, as follows: (i)
1.7 shares of InterWest Common Stock if the InterWest Price is $20.00 or less;
(ii) the number of shares obtained by dividing $34.00 by the InterWest Price
if the InterWest Price is greater than $20.00 and less than $24.12; or (iii)
1.41 shares of InterWest Common Stock if the InterWest Price is $24.12 or
greater.  If the InterWest Price is less than $17.00, Central will have the
right to terminate the Merger Agreement unless InterWest elects to adjust the
Exchange Ratio so that each share of Central Common Stock will be converted
into the right to receive the number of shares of InterWest Common Stock that
(if valued at the InterWest Price) equals $28.90.  Each holder of Central
Common Stock who would otherwise be entitled to a fractional share of
InterWest Common Stock will receive cash in lieu thereof determined by
multiplying such fraction by the InterWest Price.  Pursuant to the terms of
the Merger Agreement, all outstanding stock options under Central's stock
option plans will be assumed by InterWest.    

     If a "Triggering Event" relating to certain business combinations between
InterWest and a third party shall have occurred, the Exchange Ratio will be
based on the ten trading days beginning on and including the twentieth trading
day immediately preceding the Triggering Event.  A "Triggering Event" is
defined in the Merger Agreement to mean any one or more of the following
events:  (i)  InterWest shall have authorized, recommended, publicly proposed
or entered into an agreement with any third party to effect (a) a merger,
consolidation or similar transaction involving InterWest or any of its
significant subsidiaries, (b) the disposition of assets or deposits of
InterWest representing 25% or more of the consolidated assets or deposits of
InterWest and its subsidiaries, or (c) the issuance, sale or other disposition
of securities representing 25% or more of the voting power of InterWest or any
of its significant subsidiaries other than the issuance of InterWest Common
Stock upon the exercise of outstanding options or the conversion of
outstanding convertible securities of InterWest (an "Acquisition
Transaction"); (ii) a third party shall have made a proposal to InterWest or
its stockholders to engage in an Acquisition Transaction; (iii) a third party,
other than in connection with a transaction to which Central has given its
prior written consent, shall have filed an application or notice with the any
regulatory authority for approval to engage in an Acquisition Transaction; and
(iv) a third party shall have commenced, or shall have filed a registration
statement with respect to, a tender offer or exchange offer that would result
in such third party owning or controlling 20% or more of the then outstanding
shares of InterWest Common Stock.  InterWest has no plans, arrangements or
understandings, written or oral, regarding any business combination with a
third party or any event that would constitute a Triggering Event.
     
     On _________, 1996, the most recent date for which it was practicable to
obtain information prior to the printing of this Prospectus/Joint Proxy
Statement, the closing price per share of InterWest Common Stock, as reported
on the Nasdaq National Market, was $_____.  By way of example only, if the
InterWest Price is also $_____, each share of that holder's Central Common
Stock would be converted into ______ shares of InterWest Common Stock, which
would have a value, determined on the basis of the InterWest Price, equal to
$____.  Central shareholders should note, however, that the market price of
the InterWest Common Stock they receive will continue to be subject to market
fluctuations, as well as the future results of operations and financial
condition of InterWest, among other factors, and therefore may be worth less
than, or more than, the InterWest Price as of the date they receive their
InterWest Common Stock certificates.

EFFECTIVE DATE OF THE MERGER

     Unless the parties agree upon another date, the Effective Date of the
Merger will be the date ten business days after the fulfillment or waiver of
each of the conditions to the obligations of the parties to effect the Merger
and the granting of all regulatory approvals.  Subject to the foregoing, it is
currently anticipated that the Merger will be consummated in the second
quarter of 1996.  Either InterWest or Central may terminate the Merger
Agreement if the Effective Date does not occur on or before September 30,
1996.
<PAGE>

EXCHANGE OF CENTRAL STOCK CERTIFICATES

     As promptly as practicable after the Effective Date, InterWest will send
or cause to be sent to each holder of record of Central Common Stock
transmittal materials for use in exchanging all of such holder's certificates
representing Central Common Stock for a certificate or certificates
representing the InterWest Common Shares to which such holder is entitled and
a check or checks for such holder's fractional share interests, as
appropriate.  The transmittal materials will contain information and
instructions with respect to the surrender and exchange of such certificates.  
CENTRAL SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE
THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS. 

     Upon surrender of all of the certificates for Central Common Stock
registered in the name of a holder of such certificates (or indemnity
satisfactory to InterWest and the exchange agent selected by InterWest, if any
of such certificates are lost, stolen or destroyed), together with a properly
completed letter of transmittal, such exchange agent will mail to such holder
a certificate or certificates representing the number of InterWest Common
Shares to which such holder is entitled, together with all undelivered
dividends or distributions in respect of such shares and, where applicable, a
check for any fractional share interest (in each case, without interest).

     All InterWest Common Shares issued to the holders of Central Common Stock
pursuant to the Merger will be deemed issued as of the Effective Date. 
InterWest dividends having a record date after the Effective Date will include
dividends on all InterWest Common Shares issued in the Merger, but no dividend
or other distribution payable to the holders of record of InterWest Common
Shares at or as of any time after the Effective Date will be distributed to
the holder of any Central Common Stock certificates until such holder
physically surrenders all such certificates as hereinabove described. 
Promptly after such surrender, all undelivered dividends and other
distributions and, where applicable, a check for any fractional share
interest, will be delivered to such holder, in each case, without interest. 
After the Effective Date, the stock transfer books of Central will be closed,
and there will be no transfers on the transfer books of Central of the shares
of Central Common Stock that were outstanding immediately prior to the
Effective Date.

BACKGROUND OF THE MERGER

     During the fall of 1994, in view of Central's past performance and desire
to more effectively employ its resources, the Central Board directed
management to prepare and present a report on Central's long-term strategic
options.  In December 1994, management presented three options: growth through
acquisition; reengineering and consolidation of Central's two subsidiary
banks, or a strategic alliance with another financial institution.  After
lengthy consideration of the options, the Central Board determined to seek the
advice of legal, accounting, and investment banking professionals.  Taking
into account the advice of its financial, legal and accounting advisors and
after thorough consideration, the Central Board chose to pursue the long-term
option of strategically allying itself with another financial institution.  In
January 1995, Central engaged CFA to act as its financial advisor.  In pursuit
of the chosen option and over the course of several months, Central had
discussions with various smaller and larger financial institutions with no
productive results.

     In March 1995, management of InterWest met with Sandler O'Neill to
discuss goals for growth, capital and return on equity and to formulate
strategies for accomplishing these goals.  At that time, InterWest determined
to attempt to grow, including through acquisitions, after it completed its
pending holding company reorganization.  

     In August 1995, shortly after consummation of InterWest's holding company
reorganization, CFA independently initiated contact with InterWest to discuss
InterWest's interest in acquiring a commercial bank.  This inquiry ultimately
led to InterWest contacting Central regarding a potential business combination
between the two parties.  During August, a meeting between Stephen M. Walden,
the President and Chief Executive Officer of InterWest, and Gary M. Bolyard,
the President and Chief Executive Officer of Central, was arranged.  Mr.
Walden 
<PAGE>
and Mr. Bolyard met in Chelan, Washington in late August to discuss a possible
business combination of InterWest and Central and determined that a
combination of the two institutions appeared to meet the objectives of both
parties.  These discussions were preliminary in nature and did not result in
general agreement on the possibility or terms of such a transaction. 
Following this initial meeting, Mr. Bolyard was introduced to the entire
InterWest management team. 

     In September 1995, InterWest requested that Sandler O'Neill analyze the
combination of the two companies and act as financial advisor to InterWest
with respect to a possible transaction with Central.  Until that time, the
parties had been discussing the acquisition of Central by InterWest in
exchange for a combination of cash and InterWest Common Stock.  Central then
informed InterWest that it desired that the transaction be tax-free for
Central shareholders.

     Discussions between the parties and their financial advisors continued,
and in mid-October 1995 the parties met again to discuss the pricing of the
proposed transaction.  Because the price of InterWest Common Stock had
increased since discussions had begun, the parties began to consider
structuring the transaction so that Central shareholders would receive solely
InterWest Common Stock in exchange for the their shares of Central Common
Stock.  The parties met again twice in October to discuss employee and
benefits issues and to continue discussions regarding the pricing of a
possible transaction.

     General discussion between InterWest and Central continued through
November 1995.  The Central Board decided that it would continue discussions
if the exchange ratio were fixed at 1.7 so long as InterWest Common Stock
traded above $17.00.  During December 1995 and early January 1996, Central
permitted InterWest to conduct a detailed due diligence examination of the
assets, business and financial condition of Central.  Because InterWest Common
Stock would be issued as consideration to Central shareholders under the terms
of the proposed transaction, Central conducted a due diligence examination of
InterWest.  During this time, the executive officers of InterWest and Central
and their respective counsels and financial advisors engaged in numerous
discussions to negotiate the terms of a definitive merger agreement and
related documents.

     On January 10, 1996, the InterWest Board, along with Sandler O'Neill and
InterWest's special legal counsel, Breyer & Aguggia, reviewed the contents of
the Merger Agreement together with its exhibits.  The InterWest Board also
considered the potential benefits of the transaction, the financial and
valuation analyses of the transaction, the terms of the Merger Agreement, and
related questions and answers.  At this meeting, Sandler O'Neill presented a
financial analysis illustrating the effect of the Merger on InterWest, and the
InterWest Board unanimously approved the Merger Agreement.

     On January 10, 1996, the Central Board carefully considered the nature,
value, and prospectus for future appreciation and liquidity of the shares of
InterWest Common Stock to be received by Central shareholders in the proposed
merger.  A report from a financial point of view regarding the fairness of the
transaction was presented by Columbia Financial Advisors and a report of due
diligence was presented by Central management regarding their findings.  The
Central Board, along with its counsel, Graham & Dunn, reviewed the Merger
Agreement and considered the potential benefit of the proposed merger to
Central and its shareholders, taking into account the financial and valuation
analyses of the Merger, and the terms of the Merger Agreement.  At this
meeting, the Central Board unanimously determined that the proposed
transaction was fair to and in the best interest of Central and its
shareholders, and therefore recommended the Merger Agreement be submitted to
Central's shareholders for approval.

REASONS FOR THE MERGER AND RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

     InterWest.  The InterWest Board believes that the terms of the Merger,
which are the product of arms length negotiations between representatives of
InterWest and Central, are fair and in the best interests of InterWest and its
shareholders.  In the course of reaching its determination, the InterWest
Board consulted with legal counsel with respect to the legal duties of the
InterWest Board, the terms of the Merger Agreement and the issues related
thereto;
<PAGE>
with its accountants with respect to certain financial aspects of the
transaction; with its financial advisor with respect to the financial aspects
and fairness of the transaction; and with senior management regarding, among
other things, operational and due diligence matters.

     In reaching its determination to approve the Merger Agreement, the
InterWest Board considered, among other things, (i) information concerning the
business, market area, financial condition, earnings, operations, asset
quality and capital levels of Central and information concerning the two
companies on a combined basis; (ii) the terms of the Merger Agreement and the
other documents related to the Merger; (iii) the structure of the transaction
as a tax-free reorganization; (iv) the availability of the pooling of
interests method of accounting; (v) the financial advice provided by Sandler
O'Neill; (vi) the terms of other recent comparable combinations of thrift
institutions and thrift holding companies; and (vii) current industry,
economic and market conditions. 

     In considering the foregoing factors, the InterWest Board came to the
following conclusions, among others:

     *    The Merger would expand InterWest's presence in central Washington
and thereby give it a broader base from which to sell InterWest's product
offerings.

     *    The Merger would permit InterWest to expand Central's commercial,
small business and consumer lending activities throughout InterWest's existing
branch network faster and more efficiently than InterWest could develop such
lines of business on its own.

     *    Central's management possesses the depth and experience in
commercial lending to help integrate Central's commercial banking business
into InterWest.

     *    Central is large enough in relation to InterWest to provide
InterWest a sufficient base from which to expand Central's product offerings
and to contribute meaningfully to InterWest's income, but not so large as to
make the combination of the two companies difficult and costly.

     The InterWest Board did not ascribe relative or specific weights to the
factors that it considered or the conclusions that it reached.

FOR THE REASONS SET FORTH ABOVE, THE INTERWEST BOARD HAS
APPROVED THE MERGER AGREEMENT AS ADVISABLE AND IN THE BEST
INTERESTS OF INTERWEST AND INTERWEST SHAREHOLDERS AND
RECOMMENDS THAT THESHAREHOLDERS OF INTERWEST VOTE FOR THE
APPROVAL OF THE MERGER AGREEMENT.

     Central.  The Central Board, at its meeting held on January 10, 1996,
considered the Merger Agreement and determined it to be fair, and in the best
interests of, Central and its shareholders, customers, and employees.  In
reaching its determination, the Central Board consulted with Central
management, as well as its financial and legal advisors regarding,
respectively, the financial fairness of the Merger to Central and its
shareholders, and the legal duties of the Central Board, in connection with
the Merger and the terms of the Merger Agreement, and considered a number of
factors.  Below is a listing of the more significant factors the Central Board
considered in their decision.  The Central Board did not assign any specific
or relative weight to the below listed factors.

     *    The Central Board determined that a merger with InterWest would be a
better alternative than expanding independently through internal growth and/or
acquisitions.  After the Merger, Central's ten branches combined with
InterWest's four branches in North Central Washington will make Central the
largest financial institution in North Central Washington.  In addition,
combining with a larger financial institution will enhance Central's ability
to compete more effectively in the rapidly changing market place for banking
and financial services while maintaining its community bank flavor.
<PAGE>

     *    Confronted with changing shareholder demographics and shareholder
desires, the Central Board determined that combining with a larger company
whose stock is traded through market professionals would result in
significantly improved liquidity for Central's stockholders.

     *    Combining the management resources of both companies should result
in a greater depth of management, which should strengthen the combined
organization.

     *    Because of InterWest's relative size and resources, Central should
benefit as a result of enhanced technology and employee training which should
enable employees to better serve customers.  In addition, aligning with a
larger organization should provide enhanced career opportunities to Central's
employees.

FOR THE REASONS SET FORTH ABOVE, THE CENTRAL BOARD HAS
APPROVED THE MERGER AGREEMENT AS ADVISABLE AND IN THE BEST
INTERESTS OF CENTRAL AND CENTRAL SHAREHOLDERS AND
RECOMMENDS THAT THE SHAREHOLDERS OF CENTRAL VOTE FOR THE
APPROVAL OF THE MERGER AGREEMENT.


Opinions of Financial Advisors

     InterWest.  Pursuant to a letter agreement dated as of November 29, 1995
(the "Sandler O'Neill Agreement"), InterWest retained Sandler O'Neill as an
independent financial advisor in connection with a possible business
combination involving InterWest and Central.  Sandler O'Neill is a nationally
recognized investment banking firm whose principal business specialty is banks
and savings institutions and, in that connection, is regularly engaged in the
valuation of such businesses and their securities in connection with mergers
and acquisitions and other corporate transactions.

     Pursuant to the terms of the Sander O'Neill Agreement, Sandler O'Neill
acted as financial advisor to the Company in connection with the Merger.  In
connection therewith, at the January 10, 1996 meeting at which the Company's
Board approved and adopted the Merger Agreement, Sandler O'Neill presented a
financial analysis illustrating the effect of the Merger on InterWest.  At
that
meeting Sandler O'Neill discussed the Exchange Ratio in the Merger. 
As of the date of this proxy, Sandler O'Neill delivered a written opinion to
the InterWest Board that the Exchange Ratio in the Merger is fair, from a
financial point of view, to the holders of InterWest Common Stock (the
"Fairness Opinion").  The full text of Sandler O'Neill's Fairness Opinion,
which sets forth the procedures followed, assumptions made, matters considered
and qualifications and considerations on the review undertaken, is attached as
Appendix C to this Prospectus/Joint Proxy Statement and is incorporated herein
by reference.  The description of such opinion set forth herein is qualified
in its entirety by reference to Appendix C.  Holders of InterWest Common Stock
are urged to read the Fairness Opinion in its entirety.  Sander O'Neill's
fairness opinion is directed only to the Exchange Ratio in the Merger and does
not constitute a recommendation to any shareholder of InterWest as to how such
shareholder should vote at the InterWest Special Meeting.

     In connection with rendering its Fairness Opinion, Sandler O'Neill
performed a variety of financial analyses.  The following is a summary of such
analyses, but does not purport to be a complete description of Sandler
O'Neill's analysis.  The preparation of a fairness opinion is a complex
process involving subject judgements and is not necessarily susceptible to a
partial analysis or summary description.  Sandler O'Neill believes that its
analyses must be considered as a whole and that selecting portions of such
analyses and factors considered therein, without considering all factors and
analyses, could create an incomplete view of such analyses and processes
underlying Sandler O'Neill's opinion.  In performing its analyses, Sandler
O'Neill made numerous assumptions with respect to industry performance,
business and economic conditions and various other matters, many of which
cannot be predicted and are beyond the control of InterWest, Central and
Sandler O'Neill.  Any estimates contained in Sandler O'Neill's analyses are
not necessarily indicative of future results or values, which may be
significantly more or less favorable than such estimates. Estimates on the
values of companies do not purport to be appraisals or necessarily
<PAGE>
reflect the prices at which companies or their securities may actually be
sold.  Because such estimates are inherently subject to uncertainty, neither
InterWest nor Sandler O'Neill assumes responsibility for their accuracy.  

          Stock Trading History.  Sandler O'Neill examined the history of
trading prices and the volume of InterWest Common Stock and Central Common
Stock, the relationship between the movements in the prices of both stocks to
movements in certain stock indices, including Standard & Poor's 500 Index and
the Nasdaq Banking Index and a composite group of publicly traded savings
institutions in geographic proximity and of similar asset size.

          Comparable Company Analysis.  Using publicly available information,
Sandler O'Neill compared selected financial information and common stock
trading data for Central with similar information for selected companies that
Sandler O'Neill deemed comparable to Central.  Such comparable companies were
West Coast Bancorp, Columbia Banking System, Inc., Centennial Bancorp, United
Security Bancorporation, Cascade Bancorp, VRB Bancorp,and Evergreen Bank
(collectively, the "Comparable Institutions").  The analysis compared the
median financial performance and statistics of the Comparable Institutions
with Central's financial performance and statistics.

     This comparison showed, among other things, that using financial data for
the last twelve months ended or as of September 30, 1995, (i) the equity to
assets ratio was 7.57% for Central and 9.50% for the Comparable Institutions;
(ii) the net loan to total assets ratio was 63.12% for Central and 63.07% for
the Comparable Institutions; (iii) the net interest margin was 5.23% for
Central and 6.21% for the Comparable Institutions; (iv) the return on average
assets was 1.30% for Central and 1.50% for the Comparable Institutions; (v)
the return on average equity was 18.19% for Central and 17.89% for the
Comparable Institutions; (vi) the ratio of market price per share at January
2, 1996 to earnings per share for Central was 8.70x and 10.39x for the
Comparable Institutions; (vii) the ratio of the market price per share at
January 2, 1996 to tangible book value per share was 142.43% for Central and
163.60% for the Comparable Institutions.

          Analyses of Selected Merger Transactions.  Sandler O'Neill reviewed
113 transactions announced from January 1, 1995 to December 27, 1995 involving
public commercial banks nationwide as targets with transaction values over $15
million ("All Transactions") and 7 transactions announced from January 1, 1995
to October 12, 1995 involving public commercial banks in Idaho, Montana,
Oregon and Washington with transaction values over $15 million ("Regional
Transactions").  Sandler O'Neill reviewed the ratios of price to earnings,
price to book value, price to tangible book value, price to deposits, price to
assets, and deposit premium paid in each such transaction and computed high,
low, mean, and median ratios and premiums for the respective groups of
transactions.  Based upon the median multiples for All Transactions, Sandler
O'Neill derived an imputed range of values per share of Central's Common Stock
of $30.28 to $42.13.  Based upon the median multiples for Regional
Transactions, Sandler O'Neill derived an imputed range of values per share on
Central's Common Stock of $31.09 to $40.64.

          Discounted Dividend Stream and Terminal Value Analysis.  Sandler
O'Neill also performed an analysis which estimated the future stream of
after-tax dividend flows of InterWest through the year 2000 under various
circumstances, assuming InterWest performed in accordance with the earnings
forecasts of its management and certain variations thereof (including
variation with respect to the growth rate of assets, net interest spread,
non-interest income, non-interest expense, stock repurchases and dividend
payout ratio) (the "stand-alone projections").  To approximate the terminal
value of InterWest Common Stock at the end of the five year period, Sandler
O'Neill applied price-to-earnings multiples ranging from 8x to 17x and applied
multiples of book value ranging from 90.0% to 180.0%.  The dividend income
streams and terminal values were then discounted to present values using
different discount rates (ranging from 9.0% to 14.0%) chosen to reflect
different assumptions regarding required rates of return of holders of
prospective buyers of InterWest Common Stock.  This analysis, assuming the
current dividend payout ratio, indicated an imputed range of values per share
of InterWest Common Stock between $13.58 and $41.55.  In connection with its
analysis, Sandler O'Neill extensively used sensitivity analyses to illustrate
the effects changes in the underlying assumptions would have on the resulting
present value, and discussed these changes with the InterWest Board.
<PAGE>
     In addition, Sandler O'Neill performed an analysis which estimated the
future stream of after-tax dividend flows of the combined institution
(InterWest and Central) through the year 2000 under various circumstances (the
"Combined Institution").  In this analysis Sandler O'Neill assumed that the
Combined Institution performed in accordance with the earnings forecasts of
both InterWest's and Central's management and certain variations thereof
(including variation with respect to the Exchange Ratio, the projected cost
savings to be achieved, the growth rate of assets, net interest spread,
non-interest income, non-interest expense, and dividend payout ratio).  To
approximate the terminal value of Combined Institution's common stock at the
end of the five year period, Sandler O'Neill applied price-to-earnings
multiples ranging from 8x to 17x and applied multiples of book value ranging
from 90.0% to 180.0%.  The dividend income streams and terminal values were
than discounted to present values using different discount rates (ranging from
9.0% to 14.0%) chosen to reflect different assumptions regarding required
rates of return of holders of prospective buyers of the Combined Institution's
common stock.  This analysis, assuming the current dividend payout ratio,
indicated an imputed range of values per share of the Combined Institution's
common stock between $15.72 and $51.22.  In connection with its analysis,
Sandler O'Neill extensively used sensitivity analyses to illustrate the
effects changes in the underlying assumptions would have on the resulting
present value, and discussed these changes with the InterWest Board.

          Pro Forma Merger Analysis.  Sandler O'Neill analyzed, using
projections confirmed by InterWest and Central, certain pro forma effects
resulting from the Merger.  This analysis indicated that the transaction would
increase earnings per share of InterWest Common Stock in 1997, based on the
number of shares of InterWest Common Stock that may be issued pursuant to the
Merger Agreement.  The analysis further indicated that, based on the number of
shares of InterWest Common Stock that may be issued in the Merger, the
transaction would result in tangible book value per share dilution to
InterWest Common Stock at June 30, 1996.  In regard to the decrease in
tangible book value per share, Sandler O'Neill considered among other matters,
capitalization level and the projected equity generation capability of the
Combined Institution. 

     In connection with the Fairness Opinion, Sandler O'Neill reviewed, among
other things:  (1) the Merger Agreement; (ii) the Stock Option Agreement dated
as of January 10, 1996 by and between InterWest and Central; (iii) this
Prospectus/Joint Proxy Statement; (iv) InterWest's audited consolidated
financial statements and management's discussion and analysis of the financial
condition and results of operations contained in its annual report to
shareholders for the year ended September 30, 1995; (v) Central's audited
financial statements for the year ended December 31, 1994; (vi) InterWest's
unaudited consolidated financial statements and management's discussion and
analysis of the financial condition and results of operations contained in its
Quarterly Report on Form 10- Q for the quarter ended December 31, 1995; (vii)
Central's unaudited consolidated financial statements and management's
discussion and analysis of the financial condition and results of operations
contained in its Quarterly Reports on Form 10-QSB for the quarters ended March
31, 1995, June 30, 1995 and September 30, 1995; (viii) certain financial
analyses and forecasts of InterWest prepared by and reviewed with management
of InterWest; (ix) the views of senior management of InterWest and Central of
their respective past and current business operations, results thereof,
financial condition and future prospects; (x) the pro forma impact of the
Merger on InterWest; (xi) the historical reported price and trading activity
for Central's and InterWest's common stock, including a comparison of certain
financial and stock market information for Central and InterWest with similar
information for certain other companies the securities of which are publicly
traded; (xii) the financial terms of recent business combinations in the
savings institution and banking industries; (xiii) the current market
environment generally and the banking environment in particular; and (xiv)
such other information, financial studies, analyses and investigation and
financial, economic and market criteria as we considered relevant.

     In performing its review, Sandler O'Neill assumed and relied upon,
without independent verification, the accuracy and completeness of all of the
financial information, analyses and other information reviewed by and
discussed with them.  Sandler O'Neill did not make an independent evaluation
or appraisal of the specific assets, the collateral securing assets or the
liabilities of InterWest or Central or any of their subsidiaries, or the
collectibility of any such assets (relying, where relevant, on the analyses
and estimates of InterWest and Central).  With respect to the financial
projections reviewed with management, Sandler O'Neill assumed that they were 
reasonably prepared 
<PAGE>
on bases reflecting the best currently available estimates and judgements of
the respective managements of the respective future financial performances
will be achieved.  Sandler O'Neill also assumed that there has been no
material change in InterWest's or Central's assets, financial condition,
results of operations, business or prospects since the date of the last
financial statements noted above.  Sandler O'Neill further assumed that
InterWest will remain a going concern for all periods relevant to its analyses
and that the conditions precedent in the Merger Agreement are not waived.

     Under the Sandler O'Neill Agreement, InterWest will pay Sandler O'Neill a
transaction fee in connection with the Merger, a substantial portion of which
is contingent upon the consummation of the Merger.  Under the terms of the
Agreement, InterWest will pay Sandler O'Neill a transaction fee equal to
$300,000 of which 40% (or $120,000) was due and paid upon signing of the
Agreement, with the remainder payable upon the consummation of the Merger. 
InterWest will also pay Sandler O'Neill a fee of $50,000 for rendering the
Fairness Opinion, such fee will be credited against any fees that may become
due and payable at the Effective Date.  InterWest has also agreed to reimburse
Sandler O'Neill for its reasonable out-of-pocket expenses incurred in
connection with its engagement and to indemnify Sandler O'Neill and its
affiliates and their respective partners, directors, officers, employees,
agents, and controlling persons against certain expenses and liabilities,
including liabilities under securities laws.

     The full text of Sandler O'Neill's written opinion dated as of the date
of this Prospectus/Joint Proxy Statement is attached hereto as Appendix C to
this Prospectus/Joint Proxy Statement and is incorporated herein by reference. 
The description of the opinion set forth herein is qualified in its entirety
by reference to Appendix C.  InterWest shareholders are urged to read the
opinion in its entirety for a description of the procedures followed,
assumptions made, matters considered, and qualifications and limitations on
the review undertaken, by Sandler O'Neill in connection therewith.  

     SANDLER O'NEILL'S OPINION IS DIRECTED ONLY TO THE CONSIDERATION TO BE
PAID BY INTERWEST PURSUANT TO THE MERGER AGREEMENT AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY INTERWEST SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD
VOTE AT THE INTERWEST SPECIAL MEETING.

     Central.  CFA has delivered a written opinion to the Central Board to the
effect that, as of the date of this Prospectus/Joint Proxy Statement, the
consideration to be received by Central common shareholders pursuant to the
terms of the Merger Agreement is fair to such shareholders from a financial
point of view (the "CFA Opinion").  The Exchange Ratio has been determined by
Central and InterWest through negotiations.  The CFA Opinion is directed only
to the fairness, from a financial point of view, of the consideration to be
received and does not constitute a recommendation to any Central shareholder
as to how such shareholder should vote at the Central Annual Meeting.

     Central retained CFA as its exclusive financial advisor pursuant to an
engagement letter dated January 24, 1995 (the "Engagement Letter") in
connection with the Merger.  CFA is a regionally recognized investment banking
firm that is regularly engaged in the valuation of businesses and securities
in connection with mergers and acquisitions.  CFA is familiar with Central,
having acted as its financial advisor in connection with the Merger, having
initiated the negotiations with InterWest, and having participated in certain
of the negotiations leading to the Merger Agreement.  The Central Board
selected CFA to act as Central's exclusive financial advisor based on CFA's
experience in mergers and acquisitions and in securities valuation generally. 

     On January 10, 1996, CFA issued its opinion to the Central Board that, in
its opinion as investment bankers, the terms of the Merger as provided in the
Merger Agreement are fair, from a financial view point, to Central and it
shareholders.  Such opinion has been updated as of the date of this
Prospectus/Joint Proxy Statement.  The full text of the CFA Opinion which sets
forth the assumptions made, matters considered, and limits on its review, is
attached hereto as Appendix D.  The summary of the CFA Opinion in this
Prospectus/Joint Proxy Statement is
<PAGE>
qualified in its entirety by reference to the full text of such opinion. 

CENTRAL SHAREHOLDERS ARE URGED TO READ THE ENTIRE CFA OPINION.

     In rendering its opinion to Central, CFA reviewed, among other things,
historical financial data of Central, certain internal financial data and
assumptions of Central prepared for financial planning and budgeting purposes
furnished by the management of Central and, to the extent publicly available,
the financial terms of certain change of control transactions involving
Northwest community banks.  CFA discussed with Central's management the
financial condition, current operating results, and business outlook for
Central.  CFA also reviewed certain publicly available information concerning
InterWest and certain financial and securities data of InterWest and companies
deemed similar to InterWest.  CFA discussed with InterWest's management the
financial condition, current operating results, and business outlook for
InterWest and InterWest's plans relating to Central.  In rendering its
opinion, CFA relied, without independent verification, on the accuracy and
completeness of all financial and other information reviewed by it and did not
attempt to verify or to make any independent evaluation or appraisal of the
assets of Central or InterWest nor was it furnished any such appraisals. 
Central did not impose any limitations on the scope of the CFA investigation
in arriving at its opinion.

     CFA analyzed the aggregate merger consideration on a cash equivalent fair
market value basis using standard evaluation techniques (as discussed below)
including comparable sales multiples, net present value analysis, and net
asset value based on certain assumption of projected growth, earnings and
dividends and a range of discount rates from 16% to 18%.

     Net Asset Value is the value of the net equity of a bank, including every
kind of property and value.  This approach normally assumes the liquidation on
the date of appraisal with the recognition of the investment securities gains
or losses, real estate appreciation or depreciation, adjustments to the loan
loss reserve, discounts to the loan portfolio and changes in the net value of
other assets.  As such, it is not the best evaluation approach when valuing a
going concern because it is based on historical costs and varying accounting
methods.  Even if the assets and liabilities are adjusted to reflect
prevailing market prices and yields (which is often of limited accuracy due to
the lack of readily available data), it still results in a liquidation value, 
In addition, since this approach fails to account for the values attributable
to the going concern such as the interrelationship among Central's assets and
liabilities, customer relations, market presence, image and reputation, staff
expertise an depth, little weight was given by CFA to the net asset value
approach to valuation.

     Market Value is generally defined as the price, established on an "arms
length" basis, at which knowledgeable, unrelated buyers and sellers would
agree.  The "hypothetical" market value for a small bank with a thin market
for its common stock is normally determined by comparison to the average price
to stockholders equity, price to earnings, and price to total assets,
adjusting for significant differences in financial performance criteria and
for any lack of marketability or liquidity of the buyer.  The market value in
connection with the evaluation of control of a bank is determined by the
previous sales of small banks in the state or region.  In valuing a business
enterprise, when sufficient comparable trade data are available, the market
value approach deserves greater weighting than the net asset value approach
and similar weight as the investment value approach as discussed below. 

     CFA maintains a substantial data base concerning prices paid for banking
institution in the Northwest, particularly Washington banking institutions,
during 1988 through 1996.  This data base provides comparable pricing and
financial performance data for banking institutions sold or acquired. 
Organized by different peer groups, these data present medians of financial
performance and purchase price levels, thereby facilitating a valid
comparative purchase price analysis.  In analyzing the transaction value of
Central, CFA has considered the market approach, and has evaluated price to
stockholders equity and price to earnings multiples and the price to total
assets percentage for transactions involving Washington, Oregon, and Idaho
banking organizations with total assets less than $1 billion that sold for
100% common stock from January 1988 to January 1996.
<PAGE>

     Comparable Sales Multiples.  Columbia calculated an "Adjusted Book Value"
for the Merger using Central's adjusted September 30, 1995 stockholders equity
and the estimated June 30, 1996 stockholders equity of $32.24 and $28.85 per
share, respectively for a sample of Northwest banking institutions with assets
below $1 billion which sold between January 1988 through January 1996 and a
sample of Northwest banking institutions with total assets between $100
million and $1 billion which sold between March 1990 and October 1995.  CFA
calculated an "Adjusted Earnings Value" of $32.73 per share based on Central's
1995 earnings and the median price to earnings multiple of 12.30 for Northwest
banking organizations with assets below $1 billion which sold between January
1988 through January 1996 and a sample of Northwest banking institutions with
total assets between $100 million and $1 billion which sold between March 1990
and October 1995.

     Transaction Value as a Percentage of Total Assets.  CFA calculated the
percentage of total assets which the transaction represents as a price level
indicator.  The transaction value as a percentage of total assets facilitates
a truer price level comparison with comparable banking organizations,
regardless of the differing levels of stockholders equity and earnings.  In
this instance, a transaction value of $34.00 per share results in a
transaction value as a percentage of total assets of 17.05%.  The median price
as a percentage of total assets for a sample of Northwest banking institutions
with assets below $1 billion which sold between January 1988 through January
1996 and a sample of Northwest banking institutions with total assets between
$100 million and $1 billion which sold between March 1990 and October 1995 of
14% and 15%, respectively.

     Investment Value is sometimes referred to as the income earnings value. 
One investment value method frequented used estimates the present value of an
institution's future earnings or cash flow which is discussed below.

     Net Present Value Analysis.  The investment or earnings value of any
banking organization's stock is an estimate of the present value of future
benefits, usually earnings, dividends, or cash flow, which will accrue to the
stock.  An earnings value is calculated using an annual future earning stream
over a period of item of not less than five years and the residual or terminal
value of the earnings stream after five years, using Central's estimates of
future growth and an appropriate capitalization or discount rate.  CFA's
calculations were based on an analysis of the banking industry, Central's
earnings estimates for 1996-2000, historical levels of growth and earnings,
and the competitive situation in Central's market area.  Using discount rates
of 16% and 18%, acceptable discount rates considering the risk-return
relationship most investors would demand for an investment of this type as of
the valuation date, the "Net Present Value of Future Earnings" provided a
range of $27.80 to $32.93 per share.

     When the net asset value, market value and investment value approaches
are subjectively weighed, using the appraiser's experience and judgement, it
is CFA's opinion that the proposed transaction is fair, from a financial point
of view.

     Pursuant to the terms of the Engagement Letter, Central has agreed to pay
CFA a fee, which varies based on InterWest's stock price and the number of
Central shares outstanding, of a minimum of $50,000 and a maximum of $336,000
upon the consummation of the Merger.  In addition, Central has agreed to
reimburse CFA for its reasonable out-of-pocket expenses, including the fees
and disbursement of its counsel, and to indemnify CFA against certain
liabilities. 

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     The directors and executive officers of Central, together with their
affiliates, beneficially owned a total of ________ shares of Central Common
Stock (representing ____% of all outstanding shares of Central Common Stock)
as of the Central Record Date.  The directors and executive officers will
receive the same consideration in the Merger for their shares, including any
shares which they may acquire prior to the Effective Date pursuant to the
exercise of stock options, as the other shareholders of Central.  Certain
members of Central's management and the Central Board have certain interests
in the Merger as described below that are in addition to their interest as
<PAGE>
shareholders of Central generally.  The Central Board was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.

     Directors' and Officers' Liability.  The Merger Agreement provides that
for the five-year period following the Effective Date, InterWest will
indemnify the directors, officers and employees of Central against certain
liabilities to the extent that such persons were entitled to indemnification
under Washington law and the Articles of Incorporation and Bylaws of Central.

     Employment Agreements.  Following the Merger, Mr. Bolyard and Mr. Riordan
will enter into employment agreements with InterWest and InterWest Savings. 
Pursuant to Mr. Bolyard's agreement he will serve as Vice Chairman/Commercial
Banking of InterWest and InterWest Savings from the Effective Date until June
30, 1998.  Mr. Bolyard's initial base salary under the agreement will be
$132,000.  The agreement further provides that Mr. Bolyard will receive all
benefits that are generally provided to similarly situated senior executive
officers and that he will be eligible to participate in executive compensation
and benefit programs of InterWest and InterWest Savings.  Mr. Bolyard will
also receive certain fringe benefits, including the use of a company
automobile and payment of club dues.  If Mr. Bolyard is terminated without
cause under the agreement, he is entitled to receive his base salary for the
remaining term of the agreement.  InterWest and InterWest Savings will also
assume the obligations to Mr. Bolyard under his existing deferred compensation
agreement with Central.

     Pursuant to Mr. Riordan's employment agreement, he will serve as a Vice
President of InterWest and InterWest Savings for a period of three years
commencing on the Effective Date.  Mr. Riordan's initial base salary under the
agreement will be $75,000.  The agreement further provides that Mr. Riordan
will receive all benefits that are generally provided to similarly situated
full- time employees of InterWest Savings and that he will be eligible to
participate in InterWest Saving's executive compensation and benefit programs.
If Mr. Riordan is terminated without cause under the agreement, he is entitled
to receive his base salary for the remaining term of the agreement, unless he
is terminated without cause following a change in control of InterWest (as
defined in the agreement), in which case he is entitled to receive the greater
of his base salary for the prior 12 months or the remaining term of the
agreement.  Mr. Riordan's employment agreement with InterWest will supersede
his existing employment agreement with Central. 

     Appointments to the InterWest Board.  InterWest has agreed to appoint Mr.
Bolyard and one other person proposed by Central to the Boards of Directors of
InterWest and InterWest Savings immediately after the Effective Date.  The
other representative of Central who will be appointed to the Boards of
Directors of InterWest and InterWest Savings is expected to be Larry Carlson. 
Mr. Bolyard and Mr. Carlson are expected to be appointed to terms expiring at
the 1997 Annual Meetings of Shareholders of InterWest and InterWest has agreed
to use its best efforts to cause the election of Mr. Bolyard and Mr. Carlson
to the InterWest Board for three-year terms at such meeting.  InterWest has
also agreed to appoint Mr. Bolyard to the Executive Committees of the Boards
of Directors of InterWest and InterWest Savings and to appoint Mr. Carlson to
the Audit Committees of the Boards of Directors of InterWest and InterWest
Savings.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a discussion of certain federal income tax consequences
of the Merger that are generally applicable to Central shareholders.  This
discussion is based on currently existing provisions of the Internal Revenue
Code of 1986, as amended ("Code"), existing regulations thereunder (including
final, temporary or proposed), and current administrative rulings and court
decisions, all of which are subject to change.  Any such change, which may or
may not be retroactive, could alter the tax consequences described herein. 
The following discussion is intended only as a summary of certain principal
federal income tax consequences of the Merger and does not purport to be a
complete analysis or listing of all of the potential tax effects relevant to a
decision on whether to vote in favor of approval of the Merger Agreement.
<PAGE>

     The Merger is expected to qualify as a reorganization under Section
368(a) of the Code.  Except for cash received in lieu of a fractional share
interest in InterWest Common Stock, holders of shares of Central Common Stock
will recognize no gain or loss on the receipt of InterWest Common Stock.

     Consummation of the Merger is conditioned upon the receipt by InterWest
of an opinion of Breyer & Aguggia, special counsel to InterWest, to the effect
that if the Merger is consummated in accordance with the terms set forth in
the Merger Agreement (i) the Merger will constitute a reorganization within
the meaning of Section 368(a) of the Code; (ii) no gain or loss will be
recognized by Central shareholders who exchange all of their Central Common
Stock solely for shares of InterWest Common Stock (except for cash received in
lieu of fractional shares); (iii) the basis of shares of InterWest Common
Stock received by the shareholders of Central will be the same as the basis of
shares of Central Common Stock exchanged therefor; and (iv) the holding period
of the shares of InterWest Common Stock received by such shareholders will
include the holding period of the shares of Central Common Stock exchanged
therefor, provided such shares were held as capital assets as of the Effective
Time.

     The opinion of counsel, which will be delivered on the Closing Date, is
filed as an exhibit to the Registration Statement, and the foregoing is only a
summary of such tax consequences as described in the opinion.  An opinion of
counsel only represents counsel's best legal judgment, and has no binding
effect or official status of any kind, and no assurance can be given that
contrary positions may not be taken by the Internal Revenue Service (the
"IRS") or a court considering the issues.  Neither Central nor InterWest has
requested or will request a ruling from the IRS with regard to the federal
income tax consequences of the Merger.

     The foregoing is a general summary of all of the material federal income
tax consequences of the Merger to Central shareholders, without regard to the
particular facts and circumstances of each shareholder's tax situation and
status.  Each Central shareholder should consult his or her own tax advisor
regarding any such specific tax situation and status, including the
application and effect of federal, state, local and foreign laws and the
possible effect of changes in federal and other tax laws. 

CONDUCT OF BUSINESS PENDING THE MERGER

     Central and the Banks have agreed in the Merger Agreement not to take
certain actions without the prior approval of InterWest relating to their
operations pending consummation of the Merger.  These actions include, among
other things, (i) issuing or selling any Central Common Stock; (ii) paying any
dividends, other than a $.40 per share dividend declared on January 10, 1996
and an additional $.40 per share dividend that may be declared on July 10,
1996 if the Merger has not been completed by that date; (iii) incurring any
indebtedness for borrowed money or becoming liable for the obligations of any
other entity other than in the ordinary course of business; (iv) changing its
lending, investment, liability management or other material banking policies
in any respect; (v) imposing any lien on any share of stock held by Central;
(vi) entering into or amending any employment agreements or any employee
benefit plans or granting any salary increases (other than in the ordinary
course of business); (vii) disposing of any material portion of its assets or
acquiring any material portion of the business or property of any other
entity; (viii) amending its articles of incorporation or bylaws; (ix) settling
any claims involving any liability for material money damages; (x) entering
into, terminating or changing any material agreements, except for those
agreements that may be terminated by Central without penalty upon not more
than 60 days' prior written notice; and (xi) extending credit other than in
accordance with existing lending policies.  Moreover, Central and the Banks
are required, among other things, to operate their businesses in the usual,
regular and ordinary course and to use their best efforts to preserve their
business relationships and to retain key employees. 

CONDITIONS TO CONSUMMATION OF THE MERGER

     The obligations of Central and InterWest to consummate the Merger are
subject to, among other things, the satisfaction of the following conditions:
(i) approval of the Merger Agreement by the holders of not less than
two-thirds of the outstanding shares of Central Common Stock and by the
holders of not less than a majority of the outstanding shares of InterWest
Common Stock; (ii) receipt of all applicable regulatory approvals without any 
<PAGE>
condition that, in the opinion of InterWest, would deprive InterWest of the
material economic or business benefits of the Merger; (iv) no court or
government or regulatory authority having taken any action which enjoins or
prohibits the Merger; (v) receipt by InterWest and Central of the opinion of
Breyer & Aguggia, dated as of the Effective Date, as to certain federal income
tax consequences of the Merger; (vi) the InterWest Common Stock to be issued
to Central shareholders having been approved for listing on the Nasdaq
National Market; and (vii) Gary Bolyard and Joseph Riordan having entered into
employment agreements with InterWest and InterWest Savings.

     The obligations of InterWest are subject to the satisfaction or waiver of
certain additional conditions, including: (i) the delivery by Central of
opinions of its legal counsel and certificates executed by certain of its
executive officers as to compliance with the Merger Agreement; (ii) the
accuracy of the representations and warranties, and compliance in all material
respects with the agreements and covenants of Central; (iii) the receipt by
InterWest of a letter from Central's independent certified public accountants,
dated as of or shortly prior to the Effective Date, with respect to Central's
financial position and results of operations; (iv) receipt by InterWest of an
agreement from each "affiliate" of Central restricting the sale of InterWest
Common Stock received by such affiliate in the Merger; (v) the absence of any
material adverse change in the financial position or results of operations of
Central; (vi) the number of Dissenting Shares does not exceed 10% of the
outstanding shares of Central Common Stock; and (vii) receipt by InterWest and
Central of letters from their respective certified public accountants to the
effect that such firms concur with the respective management's conclusions as
to the appropriateness of pooling of interests accounting for the Merger,
assuming the Merger is consummated in accordance with the Merger Agreement.

     The obligations of Central are also subject to the satisfaction or waiver
of certain additional conditions, including: (i) the delivery by InterWest of
opinions of its legal counsel and certificates executed by certain of its
executive officers as to compliance with the Merger Agreement; (ii) the
accuracy of the representations and warranties, and compliance in all material
respects with the agreements and covenants of InterWest; (iii) the absence of
any material adverse change in the financial position or results of operations
of InterWest.

REGULATORY REQUIREMENTS

     The Merger is subject to prior approval by the Federal Reserve Board
under the BHC Act and the Bank Merger is subject to the approval by the FDIC
under the Bank Merger Act.  The Bank Merger is also subject to the approval of
the Department.  Based on the filing of an application for approval of the
Bank Merger with the FDIC, the Federal Reserve Board has waived the filing of
an application for approval of the Merger.  An application for approval of the
Bank Merger was filed with the FDIC and the Department on __________, 1996.

     The approval of any application merely implies satisfaction of regulatory
criteria for approval, which do not include review of the Merger from the
standpoint of the adequacy of the consideration to be received by, or fairness
to, shareholders.  Regulatory approvals do not constitute an endorsement or
recommendation of the proposed Merger.

     InterWest and Central are not aware of any governmental approvals or
compliance with banking laws and regulations that are required for
consummation of the Merger other than those described above.  Should any other
approval or action be required, it is presently contemplated that such
approval or action would be sought. There can be no assurance that any such
approval or action, if needed, could be obtained and, if such approvals or
actions are obtained, there can be no assurance as to the timing thereof.  The
Merger cannot proceed in the absence of all requisite regulatory approvals. 
See "-- Effective Date of the Merger," "-- Conditions to Consummation of the
Merger,"  and "-- Amendment; Waiver; Termination." 

     The Merger Agreement provides that if the Merger has not been consummated
by September 30, 1996, the Merger Agreement may be terminated by InterWest or
Central.  Since there is the possibility that regulatory approval may not be
obtained for a substantial period of time after approval of the Merger
Agreement by InterWest's and Central's shareholders, there can be no assurance
that the Merger will be consummated by September 30, 1996.  In addition,
should regulatory approval require any material change, a resolicitation of
shareholders may be required if regulatory approval is obtained after
shareholder approval of the Merger Agreement.

NO SOLICITATION 

     Central has agreed in the Merger Agreement that neither it nor any of its
subsidiaries will solicit, initiate or encourage inquiries or proposals with
respect to or, except as required by the fiduciary duties of the Central
Board, furnish any nonpublic information relating to or participate in any
negotiations concerning, any acquisition or purchase of all or a substantial
portion of the assets of, or a substantial equity interest in, Central or any
of its subsidiaries or any merger or other business combination with Central
or any of its subsidiaries.


STOCK OPTION AGREEMENT

     As a condition to InterWest's willingness to enter into the Merger
Agreement, and in consideration thereof, Central issued to InterWest the
Option to purchase, under certain conditions, up to 201,898 shares of Central
Common Stock at a Purchase Price of $26.00 per share, subject to adjustment in
certain circumstances.  The Option was granted to InterWest pursuant to the
Stock Option Agreement.  The number of shares of Central Common Stock subject
to the Option represents approximately 19.9% of the outstanding shares of
Central Common Stock as of the Central Record Date, before giving effect to
the issuance of such shares.  InterWest does not have any voting rights with
respect to the shares of Central Common Stock subject to the Option prior to
exercise of the Option. 

     If InterWest is not in material breach of the Stock Option Agreement or
the Merger Agreement and no injunction against delivery of the shares covered
by the Option is in effect, InterWest may exercise the Option in whole or in
part, at any time and from time to time following the happening of certain
events (each a "Purchase Event"), including, among others:

(i)  Central taking certain actions (each an "Acquisition Transaction"),
including, among others, authorizing, recommending or entering into an
agreement with any third party to effect (a) a merger, consolidation or
similar transaction involving Central or any of its significant subsidiaries,
(b) the sale, lease, exchange or other disposition of 20% or more of the
consolidated assets or deposits of Central and its subsidiaries, or (c) the
issuance, sale or other disposition of 20% or more of the voting power of
Central or any of its significant subsidiaries (other than the issuance of
Central Common Stock upon exercise of options outstanding under the Central
Option Plan); or (ii)  the acquisition or the right to acquire by any third
party of 15% or more (or, if such party beneficially owned more than 15% on
the date of the Merger Agreement, such party acquires an additional 5% or
more) of the voting power of Central or any of its significant subsidiaries.

     The Option will terminate upon the earliest of certain events, including:
(i) consummation of the Merger; (ii) termination of the Merger Agreement by
Central (a "Central Termination") prior to the happening of a Purchase Event
or a Preliminary Purchase Event (as defined below); (iii) 15 months after
termination of the Merger Agreement by Central other than pursuant to a
Central Termination; or (iv) 15 months after termination of the Merger
Agreement by InterWest.  A "Preliminary Purchase Event" is defined to include,
among others: (a) commencement by any third party of a tender or exchange
offer to purchase 20% or more of the outstanding shares of Central Common
Stock (a "Tender or Exchange Offer"); (b) failure of the holders of Central
Common Stock to approve the Merger Agreement after public announcement that a
third party proposes to engage in an Acquisition Transaction or commences or
files a registration statement under the Securities Act with respect to a
Tender or Exchange Offer; (c) any third party shall have proposed to Central
or its shareholders, publicly or in any writing that becomes publicly
disclosed, to engage in an Acquisition Transaction; (d) after a proposal is
made by a third party to Central or its shareholders to engage in an
Acquisition Transaction, Central breaches any covenant or obligation in the
Merger Agreement (subject to certain limitations set forth in the Stock Option
Agreement); or (e) any third party files an application with any federal or
state bank regulatory authority for approval to engage in an Acquisition
Transaction.
<PAGE>

     The Stock Option Agreement and the Option are intended to increase the
likelihood that the Merger will be consummated according to the terms set
forth in the Merger Agreement and may be expected to discourage competing
offers to acquire Central from potential third party acquirors because the
Option could increase the cost of such an acquisition.

     To InterWest and Central's knowledge, no event which would permit the
exercise of the Option has occurred as of the date of this Prospectus/Joint
Proxy Statement.

     A copy of the Stock Option Agreement is set forth as Appendix B to this
Prospectus/Joint Proxy Statement, and reference is made thereto for the
complete terms of the Stock Option Agreement and the Option.  The foregoing
discussion is qualified in its entirety by reference to the Stock Option
Agreement.

DISSENTERS' RIGHTS

     In accordance with Chapter 13 of the WBCA (Chapter 23B.13 of the Revised
Code of Washington), Central's shareholders have the right to dissent from the
Merger and to receive payment in cash for the "fair value" of their Central
Common Stock.  Under applicable Washington law, InterWest shareholders will
not have any dissenters' rights.

     If Central shareholders perfect dissenters' rights with respect to more
than 10% of the outstanding shares of Central Common Stock, InterWest may
elect not to consummate the Merger.  Additionally, if Central shareholders
perfect dissenters' rights with respect to more than 10% of the outstanding
shares of Central Common Stock and InterWest elects to consummate the Merger,
the Merger will not qualify for pooling of interests accounting treatment. 
Central shareholders electing to exercise dissenters' rights must comply with
the provisions of Chapter 13 in order to perfect their rights.  Central and
InterWest will require strict compliance with the statutory procedures.  The
following is intended as a brief summary of the material provisions of the
Washington statutory procedures required to be followed by a Central
shareholder in order to dissent from the Merger and perfect the shareholder's
dissenters' rights.  This summary, however, is not a complete statement of all
applicable requirements and is qualified in its entirety by reference to
Chapter 13 of the WBCA, the full text of which is set forth in Appendix E
hereto.

     A shareholder who wishes to assert dissenters' rights must (a) deliver to
Central before the Central Special Meeting written notice of the shareholder's
intent to demand payment for the shareholder's shares if the Merger is
effected, and (b) not vote such shares in favor of the Merger.  A shareholder
wishing to deliver such notice should hand deliver or mail such notice to
Central at the following address:

                     Central Bancorporation
                        301 North Chelan
                   Wenatchee, Washington 98801
                    Attn: Corporate Secretary
                                
     A shareholder who wishes to exercise dissenters' rights generally must
dissent with respect to all the shares the shareholder owns or over which the
shareholder has power to direct the vote.  However, if a record shareholder is
a nominee for several beneficial shareholders some of whom wish to dissent and
some of whom do not, then the record holder may dissent with respect to all
the shares beneficially owned by any one person by notifying Central in
writing of the name and address of each person on whose behalf the record
shareholder asserts dissenters' rights.  A beneficial shareholder may assert
dissenters' rights directly by submitting to Central the record shareholder's
written consent and by dissenting with respect to all the shares of which such
shareholder is the beneficial shareholder or over which such shareholder has
power to direct the vote. 

     A shareholder who does not deliver to Central prior to the Central
Special Meeting a written notice of the shareholder's intent to demand payment
for the "fair value" of the shares will lose the right to exercise
<PAGE>
dissenters' rights.  In addition, any shareholder electing to exercise
dissenters' rights must either vote against the Merger or abstain from voting. 


     If the Merger is effected, InterWest shall, within ten days after the
Effective Date of the Merger, deliver a written notice to all shareholders who
properly perfected their dissenters' rights.  Such notice will, among other
things, (a) state where the payment demand must be sent and where and when
certificates for certificated shares must be deposited; (b) inform holders of
uncertificated shares to what extent transfer of the shares will be restricted
after the payment demand is received; (c) supply a form for demanding payment;
and (d) set a date by which InterWest must receive the payment demand, which
date will be between 30 and 60 days after notice is delivered.

     A shareholder wishing to exercise dissenters' rights must at that time
file the payment demand and deliver share certificates as required in the
notice.  Failure to do so will cause such person to lose his or her
dissenters'
rights.

     Within 30 days after the Merger occurs or receipt of the payment demand,
whichever is later, InterWest shall pay each dissenter with properly perfected
dissenters' rights InterWest's estimate of the "fair value" of the
shareholder's interest, plus accrued interest from the Effective Date of the
Merger.  With respect to a dissenter who did not beneficially own Central
shares prior to the public announcement of the Merger, InterWest is required
to
make the payment only after the dissenter has agreed to accept the payment in
full satisfaction of the dissenter's demands. "Fair value" means the value of
the shares immediately before the Effective Date of the Merger, excluding any
appreciation in anticipation of the Merger.  The rate of interest is generally
required to be the rate at which InterWest can borrow money from other banks. 
It is the current intention of InterWest to estimate the fair value of Central
Common Stock to be $______ per share, which represents the price paid for
Central Common Stock in the last transaction for which a price is known to
Central management prior to the date on which the Merger Agreement was signed. 

     A dissenter dissatisfied with InterWest's estimate of the fair value may
notify InterWest of the dissenter's estimate of the fair value.  If InterWest
does not accept the dissenter's estimate and the parties do not otherwise
settle on a fair value then InterWest must within 60 days petition a court to
determine the fair value. 

     In view of the complexity of Chapter 13 of the WBCA, shareholders of
Central who may wish to dissent from the Merger and pursue appraisal rights
should consult their legal advisors. 

Amendment; Waiver; Termination

     InterWest may elect to modify the structure of the Merger; provided,
however, that InterWest shall not have the right to make any revision to the
structure of the Merger which (i) changes the amount or kind of the
consideration which the Central shareholders are entitled to receive or (ii)
adversely affects the tax treatment to Central shareholders of receiving such
consideration.  Prior to the Effective Date of the Merger, any condition of
the Merger Agreement may (to the extent allowed by law) be waived in writing
by the party benefitted by the provision or may be amended or modified by an
agreement in writing approved by the Boards of Directors of InterWest and
Central.  After approval of the Merger Agreement by the shareholders of
Central, the Merger Agreement may not, without further approval of such
shareholders, be amended in any manner that would alter the consideration to
be received by Central shareholders in exchange for their Central Common
Stock.  

     The Merger Agreement may be terminated at any time prior to the Effective
Date of the Merger, either before or after approval by the InterWest and
Central shareholders, as follows:  (i) by the mutual consent of the parties;
(ii) by either party if the other party has committed a material breach that
cannot be or has not been cured within 30 days after the giving of written
notice of such breach; (iii) by either party if the Closing Date shall not
have occurred by September 30, 1996; (iv) by either party if the shareholders
of InterWest or Central fail to approve the Merger Agreement; or (v) by
Central if the InterWest Price is less than $17.00 and InterWest, in its sole
<PAGE>
discretion, does not elect to adjust the Exchange Ratio so that the InterWest
Price multiplied by the Exchange Ratio equals $28.90.


     In the event of the valid termination of the Merger Agreement by either
InterWest or Central, the obligations of the parties to the Merger Agreement
shall terminate, and there will be no liability on the part of either party or
their officers or directors except for liability for breach of the Merger
Agreement or for any misstatement or misrepresentation made prior to such
termination.

RESALE OF INTERWEST COMMON STOCK

     The shares of InterWest Common Stock issuable to shareholders of Central
upon consummation of the Merger have been registered under the Securities Act. 
Such shares may be traded freely and without restriction by those shareholders
not deemed to be "affiliates" of Central or InterWest as that term is defined
in the rules under the Securities Act.  InterWest Common Stock received by
those shareholders of Central who are deemed to be "affiliates" of Central may
be resold without registration as provided for by Rule 145, or as otherwise
permitted under the Securities Act.  Persons who may be deemed to be
affiliates
of Central generally include individuals or entities that control, are
controlled by or are under common control with, Central, and may include the
executive officers and directors of Central as well as certain principal
shareholders of Central.  In the Merger Agreement, Central has agreed to use
its best efforts to cause each person who may be deemed to be an affiliate of
Central to enter into an agreement with InterWest providing that such
affiliate will not sell, transfer, or otherwise dispose of the shares of
InterWest Common Stock to be received by such person in the Merger except in
compliance with the applicable provisions of the Securities Act and the rules
and regulations promulgated thereunder.  This Prospectus/Joint Proxy Statement
does not cover any resales of InterWest Common Stock received by affiliates of
Central.

ACCOUNTING TREATMENT

     It is expected that the pooling of interests method of accounting will be
used to reflect the Merger.  As required by generally accepted accounting
principles, under pooling of interests accounting, as of the effective date of
the Merger, the assets and liabilities of Central would be added to those of
InterWest at their recorded book values and the shareholders' equity accounts
of InterWest and Central would be combined on InterWest's consolidated balance
sheet.  On a pooling of interests accounting basis, income and other financial
statements of InterWest issued after consummation of the Merger would be
restated retroactively to reflect the consolidated combined financial position
and results of operations of InterWest and Central as if the Merger had taken
place prior to the periods covered by such financial statements.  In order for
the Merger to qualify for pooling of interests accounting treatment, among
other things, substantially all (90% or more) of the outstanding Central
Common Stock must be exchanged for InterWest Common Stock.  

     The unaudited pro forma dates contained in this Prospectus/Joint Proxy
Statement has been prepared using the pooling of interests method of
accounting to account for the Merger.  See "PRO FORMA FINANCIAL INFORMATION."


EXPENSES

     The Merger Agreement provides that InterWest and Central will each pay
their own expenses in connection with the Merger Agreement and the
transactions contemplated thereby, except that printing expenses for this
Prospectus/Joint Proxy Statement will be shared equally.

                 PRO FORMA FINANCIAL INFORMATION

     The unaudited pro forma condensed combined financial statements presented
below reflect consummation of the Merger.  The following unaudited pro forma
condensed combined statement of financial condition as of December 31, 1995
combines the historical consolidated statements of financial condition of
InterWest and Central as if the Merger had occurred on such date after giving
effect to certain pro forma adjustments described in the accompanying notes. 
The following unaudited pro forma condensed combined statements of income are
presented as if the Merger had been consummated at the beginning of each
period presented.  InterWest's fiscal year ends September 30 and Central's
fiscal year ends December 31.  The unaudited pro forma condensed combined
statements of income for the three years ended September 30, 1995, 1994 and
1993 present the results of operations of InterWest for the fiscal year ended
September 30, 1995, 1994 and 1993 combined with the results for operations of
Central with the fiscal years ended December 31, 1995, 1994 and 1993,
respectively.  The InterWest historical consolidated financial statement data
as of and for the three months ended December 31, 1995 have been prepared on
the same basis as the historical information derived from audited financial
statements, and in the opinion of management, contain all adjustments,
consisting only of normal recurring accruals, necessary for the fair
presentation of results of operations for such periods.  The pro forma
condensed combined financial statements have been prepared based on a 1.7
Exchange Ratio.  The 1.7 Exchange Ratio used in the pro forma information is
based on the last reported sales price on the Nasdaq National Market of
InterWest Common Stock, on     , 1996, which was $     per share.  The actual
Exchange Ratio will depend on the InterWest Price (which will not be known
until shortly before the Effective Date) and may be higher or lower than 1.7.  

     The unaudited pro forma condensed combined financial statements and notes
thereto reflect the application of the pooling of interests method of
accounting.  See "THE MERGER -- Accounting Treatment."  The unaudited pro
forma condensed combined financial statements included herein are not
necessarily indicative of the future results of operations or the future
financial position of the combined entities or the results of operations and
financial position of the combined entities that would have actually occurred
had the transactions been in effect as of the dates or for the periods
presented.  

     InterWest and Central estimate that they will incur direct transaction
costs of approximately $500,000 associated with the Merger which will be
charged to operations during the fiscal quarter in which the Merger is
consummated.  There can be no assurance that InterWest will not incur charges
in subsequent quarters to reflect costs associated with the Merger or that
management will be successful in their efforts to integrate the operations of
the two companies.

     The unaudited pro forma condensed combined financial statements should be
read in conjunction with the separate historical consolidated financial
statements of InterWest and Central, including the notes thereto, and the
other documents incorporated by reference herein.  See "AVAILABLE
INFORMATION," "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and the

NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1.Periods Combined

     InterWest's consolidated statements of operation for each of the years in
the three-year period ended September 30, 1995 and thethree months ended
December 31, 1995 have been combined with the Central consolidated statements
of operations for each of the years in the three-year period ended December
31, 1995 and the three months ended December 31, 1995.

     The InterWest consolidated statement of financial condition as of
December 31, 1995 has been combined with the Central consolidated statement of
financial condition as of December 31, 1995. 

Note 2.Pro Forma Net Income Per Share

     The pro forma condensed combined statement of income for InterWest and
Central have been prepared as if the Merger was completed at the beginning of
the periods presented.  The pro forma combined net income per share is based
upon combined historical net income for InterWest and Central divided by the
average pro forma common shares of the combined entities. 

Note 3.Basis of Presentation

     Pro forma basis of presentation.  The pro forma condensed combined
financial statements reflect the issuance of 1,724,762 shares of InterWest
common stock in exchange for an aggregate of 1,014,565 shares of Central
common stock in connection with Merger based on the exchange ratio of 1.7
shares of InterWest Common Stock for every share of Central Common Stock.

     Merger transaction costs.  InterWest and Central estimate they will incur
direct transaction costs of approximately $900,000 associated with the Merger,
consisting of transaction fees for investment bankers, attorneys, accountants,
financial printing and other related charges.  These nonrecurring costs will
be charges to operations in the fiscal quarter in which the Merger is
consummated.  The pro forma condensed combined statement of financial
condition gives effect to such expenses as if they had been accrued as of
December 31, 1995, but the effect of these costs have not been reflected in
the pro forma condensed combined statements of operations.

Note 4.Conforming Adjustments

     There have been no adjustments required to conform the accounting
policies of the combined company.  There are no intercompany transactions. 

                BUSINESSES OF THE PARTIES TO THE MERGER

InterWest and InterWest Savings 

     InterWest is a bank holding company registered under the BHC Act.  The
business of InterWest consists primarily of holding 100% of the capital stock
of InterWest Savings.  At December 31, 1995, InterWest had total assets of
$1.3 billion, total loans and mortgage-backed securities of $1.1 billion,
total deposits of $866.0 million and stockholders' equity of $97.1 million.

     InterWest Savings is a state-chartered savings bank and is regulated by

limits under the SAIF of the FDIC.  InterWest Savings is a community oriented
savings bank which has traditionally 
<PAGE>
offered a variety of savings products to its retail customers while
concentrating its lending activities on loans for the purchase or construction
of residential real estate.  Lending activities have also included the
origination of multi-family residential, commercial real estate and consumer
loans.  In addition, InterWest Savings has maintained a significant portion of
its assets in mortgage-backed and related securities.  As of December 31,
1995, InterWest Savings conducted its business through 30 full-service branch
offices and one lending office located in small cities and towns in the
western and central parts of the State of Washington.  These smaller cities
and towns are generally outside Washington's most densely populated cities,
such as Seattle and Spokane.  InterWest believes it is easier to develop
long-term customer relationships in outlying areas and that such relationships
lead to increased repeat business and greater customer loyalty. 

     Financial and other information relating to InterWest, including
information relating to InterWest's directors and executive officers, is set
forth in InterWest's Annual Report on Form 10-K for the year ended September
30, 1995, Quarterly Report on Form 10-Q for the period ended December 31, 1995
and Annual Meeting proxy statement, copies of which may be obtained from

had consolidated total assets of $203.4 million, total loans and mortgage
backed securities of $137.9 million, total customer deposits of $179.9

             DESCRIPTION OF INTERWEST CAPITAL STOCK

InterWest Common Stock were issued and outstanding.  InterWest Common Stock is
listed for trading on the Nasdaq National Market under the symbol "IWBK."

The following summary does not purport to be a complete description of the
applicable provisions of the InterWest Articles of Incorporation and Bylaws or
of applicable statutory or other law, and is qualified in its entirety by
reference thereto.  See "AVAILABLE INFORMATION." 

Voting Rights  

     The holders of InterWest Common Stock possess exclusive voting rights in
InterWest.  Each holder of InterWest Common Stock is entitled to one vote for
each share held of record on all matters submitted to a vote of holders of
InterWest Common Stock.  Holders of shares of InterWest Common Stock are not
entitled to cumulate votes for the election of directors.
<PAGE>

Dividends

     The holders of InterWest Common Stock are entitled to such dividends as
the InterWest Board may declare from time to time out of funds legally
available therefor.  Dividends from InterWest depend upon the receipt by
InterWest of dividends from InterWest Savings because InterWest has no source
of income other than dividends from InterWest Savings.   

Liquidation 

     In the event of liquidation, dissolution or winding up of InterWest, the
holders of shares of InterWest Common Stock are entitled to share ratably in
all assets remaining after payment of all debts and other liabilities of
InterWest.

Other Characteristics  

     Holders of InterWest Common Stock do not have any preemptive, conversion
or other subscription rights with respect to any additional shares of
InterWest Common Stock which may be issued.  Therefore, the InterWest Board
may authorize the issuance and sale of shares of capital stock of InterWest
without first offering them to existing shareholders of InterWest.  InterWest
Common Stock is not subject to any redemption or sinking fund provisions.  The
outstanding shares of InterWest Common Stock are, and the shares to be issued
in the Merger will be, fully paid and non-assessable.  

     The InterWest Articles of Incorporation and Bylaws contain provisions
that may have the effect of discouraging persons from acquiring large blocks
of InterWest Common Stock or delaying or preventing a change in control of
InterWest.  These provisions include the classification of the InterWest Board
into three classes with the term of only one class expiring each year and
requirements for the approval of certain business combinations.  See
"COMPARISON OF SHAREHOLDERS' RIGHTS."


               COMPARISON OF SHAREHOLDERS' RIGHTS

     InterWest is incorporated under the laws of the State of Washington and,
accordingly, the rights of InterWest's shareholders are governed by
InterWest's Articles of Incorporation, Bylaws and the WBCA.  Central is also
incorporated under the laws of the State of Washington and, accordingly, the
rights of Central's shareholders are governed by Central's Articles of
Incorporation, Bylaws and the WBCA.

     Upon consummation of the Merger, shareholders of Central will become
shareholders of InterWest, and, as such, their rights will be governed by
InterWest's Articles of Incorporation, Bylaws and the WBCA.  The following is
a summary of material differences between the Articles of Incorporation and
Bylaws of InterWest and the Articles of Incorporation and Bylaws of Central. 
This discussion is not intended to be a complete statement of the differences
affecting the rights of shareholders and is qualified in its entirety by
reference to the governing law and the articles of incorporation and bylaws of
each corporation.

Payment of Dividends  

     InterWest.  Under Washington law, dividends may be paid only if, after
giving effect to the dividend, InterWest will be able to pay its debts as they
become due in the ordinary course of business and InterWest's total assets
will not be less than the sum of its total liabilities plus the amount that
would be needed, if InterWest were to be dissolved at the time of the
dividend, to satisfy the preferential rights of persons whose right to payment
is superior to those receiving the dividend.
<PAGE>

     Central.  Under Washington law, dividends may be paid only if,after
giving effect to the dividend, Central will be able to pay its debts as they
become due in the ordinary course of business and Central's total assets will
not be less than the sum of its total liabilities plus the amount that would
be needed, if Central were to be dissolved at the time of the dividend, to
satisfy the preferential rights of persons whose right to payment is superior
to those receiving the dividend.

Size of Board of Directors  

     InterWest.  InterWest's Articles of Incorporation provide that its Board
of Directors shall consist of not less than five nor more than 15 members,
with the current number set at nine by the Bylaws of InterWest.  The Bylaws of
InterWest provide that the Board of Directors or the shareholders may change
the authorized number of directors within the stated range by amending the
Bylaws, which must be approved by a majority of the outstanding shares
entitled to vote or by a majority of the directors.  Changes in the size of
the range may be made by an amendment to InterWest's Articles of
Incorporation, which must be approved by a majority of the outstanding shares
entitled to vote.  The effect of such provisions may be to make it difficult
for a person or entity immediately to acquire control of InterWest through an
increase in the number of InterWest's directors and election of such person's
or entity's nominees to fill the newly created vacancies. 

     Central.  Central's Articles of Incorporation provide that its Board of
Directors shall consist of not less than five nor more than 18 members, with
the current number fixed by resolution approved by at least a two-thirds vote
of the total number of directors.  The number of directors may be increased by
not more than two directors by the Central Board between annual meetings of
shareholders.  Changes in the size of the stated range may be made by an
amendment to Central's Articles of Incorporation, which must be approved by a
majority of the outstanding shares entitled to vote.

Classified Board of Directors  

     InterWest.  A classified board is one in which a certain number, but not
all, of the directors are elected on a rotating basis each year.  InterWest's
Articles of Incorporation provide for a Board of Directors divided into three
classes, with members of each class of directors being elected for a term of
three years.  This method of electing directors makes a change in the
composition of the Board of Directors, and a potential change in control of a
corporation, a lengthier and more difficult process.  Since the terms of only
one-third of the incumbent directors expire each year, it requires at least
two annual elections for the shareholders to change a majority of the
directors.  In the absence of the provisions of the Articles of Incorporation
classifying the Board, all of the directors would be elected each year.  

     Central.  Central's Articles of Incorporation provide for a Board of
Directors divided into three classes, with members of each class of directors
being elected for a term of three years. 

Cumulative Voting 

     InterWest.  Cumulative voting entitles each shareholder to cast a number
of votes in the election of directors equal to the number of such
shareholders' shares of Common Stock multiplied by the number of directors to
be elected, and to distribute such votes among one or more of the nominees to
be elected.  InterWest's Articles of Incorporation eliminate cumulative
voting.  The absence of cumulative voting rights limits the ability of
minority shareholders to obtain representation on the InterWest Board.  

     Central.  Central's Articles of Incorporation eliminate cumulative
voting.
<PAGE>

Removal of Directors  

     InterWest.  InterWest's Articles of Incorporation provide that at a
meeting of shareholders called expressly for that purpose, any director or the
entire Board of Directors may be removed for cause by a vote of the holders of
a majority of the shares then entitled to vote at such meeting.  The
requirement that directors may be removed only upon a majority vote and only
for cause makes it difficult for a person or entity immediately to acquire
control of InterWest's Board through the removal of existing directors and the
election of such person's or entity's nominees to fill the newly created
vacancies.

     Central.  Central's Articles of Incorporation provide that no director
may be removed from office without cause except by a vote of two-thirds of the
shares then entitled to vote at an election of directors.

Vacancies on the Board of Directors

      InterWest.  The Bylaws of InterWest provide that any vacancy on the
Board of Directors may be filled by the affirmative vote of a majority of the
remaining directors, and any director so appointed is to serve for the
unexpired term of his or her predecessor.  A director appointed by reason of
an increase in the number of directors may serve only until the next election
of directors. 

     Central.  Central's Articles of Incorporation provide that the Board of
Directors may appoint persons to fill vacancies created by an increase in the
size of the Central Board.

Special Meetings of Shareholders and Action Without a Meeting   

     InterWest.  The Articles of Incorporation of InterWest provide that
special meetings of shareholders may be called by the president, the board of
directors or holders of not less than a majority of the outstanding shares of
stock.  This restriction on the calling of special shareholders' meetings may
deter hostile takeovers of InterWest by making it more difficult for a person
or entity to obtain immediate control of InterWest between one annual meeting
and the next.  Pursuant to InterWest's Bylaws, any action required or
permitted to be taken at a meeting of shareholders may be taken without a
meeting if a consent in writing is signed by all of the shareholders entitled
to vote on the matter. 

     Central.  The Bylaws of Central provide that special meetings of
shareholders may be called at any time by the Chairman, the President, a
majority of the Central Board, or any shareholder or shareholders holding in
the aggregate not less than one-tenth of all shares entitled to vote at the
special meeting.  Pursuant to the WBCA, any action required or permitted to be
taken at a shareholders' meeting may be taken without a meeting if a consent
is signed in writing by all of the shareholders entitled to vote on the
action.

Advance Notice Requirements for Nominations of Directors and Presentation of
New Business at Meetings of Shareholders 

     InterWest.  The Bylaws of InterWest generally provide that any
shareholder desiring to make a nomination for the election of directors or a
proposal for new business at a meeting of shareholders must submit written
notice to InterWest at least 30 days and not more than 60 days in advance of
the meeting, together with certain information relating to the nomination or
new business.  Failure to comply with these advance notice requirements will
preclude such nominations or new business from being considered at the
meeting.  Management believes that it is in the best interests of InterWest
and its shareholders to provide sufficient time to enable management to
disclose to shareholders information about a dissident slate of nominations
for directors.  This advance notice requirement may also give management time
to solicit its own proxies in an attempt to defeat any dissident slate of
nominations, should management determine that doing so is in the best interest
of shareholders generally.  Similarly, adequate advance notice of shareholder
proposals will give management time to study such proposals and to determine
whether to 
<PAGE>
recommend to the shareholders that such proposals be adopted.  In certain
instances, such provisions could make it more difficult to oppose management's
nominees or proposals, even if shareholders believe such nominees or proposals
are in their best interests. 

     Central.  The Articles of Incorporation of Central provide that any
shareholder desiring to make a nomination for the election of directors must
submit such nomination in writing to the Chairman of Central not less than 14
days nor more than 50 days prior to any meeting of shareholders called for the
election of directors, provided that if less than 21 days' notice of the
meeting is given to shareholders, such nomination must be delivered or mailed
not later than the close of business on the seventh day following the day on
which the notice of the meeting was mailed.  Such nomination must contain
certain information relating to the nomination.  Nominations not made in
accordance with the Articles of Incorporation may be disregarded.

Approval of Mergers, Consolidations, Sale of Substantially All Assets and
Dissolution  

     InterWest.  Article X of InterWest's Articles of Incorporation requires
the approval of the holders of (i) at least 80% of InterWest's outstanding
shares of voting stock, and (ii) at least a majority of InterWest's
outstanding shares of voting stock, not including shares held by a "Related
Person," to approve certain"Business Combinations," except in cases where the
proposed transaction has been approved in advance by a majority of those
members of the InterWest Board who were directors prior to the time when the
Related Person became a Related Person.  In the event the requisite approval
of the Board were given, the normal vote requirement of applicable Washington
law would apply, or, for certain transactions, no shareholder vote would be
necessary.  The term "Related Person" is defined to include any individual,
corporation, partnership or other entity which owns beneficially or controls,
directly or indirectly, 10% or more of the outstanding shares of voting stock
of InterWest.  The provisions of Article X apply to any "Business Combination"
which is defined to include among other things: (i) any merger or
consolidation of InterWest or any of its affiliates with or into any Related
Person; (ii) any sale, lease, exchange, mortgage, transfer, or other
disposition of all or a substantial part of the assets of InterWest or any of
its affiliates to any Related Person (the term "substantial part" is defined
to include more than 25% of InterWest's total assets); (iii) any sale, lease,
exchange, or other transfer by any Related Person to InterWest of all or a
substantial part of the assets of Related Person; (iv) the acquisition by
InterWest of any securities of the Related Person; (v) any reclassification of
InterWest Common Stock; and (vi) any agreement, contract or other arrangement
providing for any of the transactions described above.  The increased
shareholder vote required to approve a Business Combination may have the
effect of foreclosing mergers and other business combinations which a majority
of shareholders deem desirable and place the power to prevent such a merger or
combination in the hands of a minority of shareholders.  

     InterWest's Articles of Incorporation require InterWest's Board of
Directors to consider certain factors in addition to the amount of
consideration to be paid when evaluating certain business combinations or a
tender or exchange offer.  These additional factors include:  (i) the social
and economic effects of the transaction; (ii) the business and financial
condition and earnings prospects of the acquiring person or entity; and (iii)
the competence, experience, and integrity of the acquiring person or entity
and its management.  

     Central.  Central's Articles of Incorporation require the affirmative
vote of two-thirds of the total shares attributable to persons other than a
"Control Person" for approval of certain "Business Combinations" between
Central and any Control Person, except in cases where the proposed transaction
has been approved in advance by a majority of those members of the Central
Board who were directors prior to the time the Control Person acquired
beneficial ownership of 10% or more the outstanding shares of Central Common
Stock.  The term "Control Person" is defined as any individual, corporation,
partnership or other entity which, together with affiliates and associates, is
the beneficial owner in the aggregate of 20% or more of the outstanding shares
of Central Common Stock.  The term "Business Combination" is defined to mean
(i) any merger or consolidation of Central with a Control Person; (ii) any
sale, lease, exchange transfer or other disposition of 10% or more of the
assets of Central or a subsidiary to a Control Person; (iii) any merger or
consolidation of a Control person with Central; (iv) any sale, lease,
exchange, transfer or other disposition of 10% of the assets of a Control
Person to Central; (v) the issuance of any securities 
<PAGE> of Central to a Control Person; (vi) the acquisition by Central of any
securities of a Control Person; (vii) any reclassification of Central Common
Stock or recapitalization consummated with five years after a Control Person
becomes a Control Person; or (viii) any agreement, contract or other
arrangement providing for any of the transactions described above.

     Central's Articles of Incorporation require the Central Board when
evaluating any offer of another party to make a tender or exchange offer for
any equity security of Central, to merge or consolidate Central with another
corporation or to purchase all or substantially all of the assets of Central
to give due consideration to the social and economic effects on the employees,
customers, suppliers and other constituents of Central and on the communities
in which Central operates or is located.

Rights of Shareholders to Dissent

     InterWest.  Under the WBCA, shareholders of InterWest will generally have
dissenter's appraisal rights in connection with (i) a plan of merger to which
InterWest is a party; (ii) a plan of share exchange to which InterWest is a
party as the corporation whose shares will be acquired; (iii) certain sales or
exchanges of all, or substantially all, of InterWest's property other than in
the regular course of business; and (iv) amendments to InterWest's Articles of
Incorporation effecting a material reverse stock split.  However, shareholders
generally will not have such dissenters' rights if shareholder approval is not
required by the WBCA for the corporate action.  Shareholders of InterWest do
not have dissenters' rights in connection with the Merger.

     Central.  Under the WBCA, shareholders of Central generally have
dissenter's appraisal rights in connection with (i) a plan of merger to which
Central is a party; (ii) a plan of share exchange to which Central is a party
as the corporation whose shares will be acquired; (iii) certain sales or
exchanges of all, or substantially all, of Central's property other than in
the regular course of business; and (iv) amendments to Central's Articles of
Incorporation effecting a material reverse stock split.  However, shareholders
generally will not have such dissenters' rights if shareholder approval is not
required for the corporate action.  Shareholders of Central have dissenters'
rights in connection with the Merger.  See "THE MERGER -- Dissenters' Rights."

Indemnification of Officers and Directors and Limitation of Liability  

     InterWest.  Pursuant to InterWest's Articles of Incorporation InterWest
will, to the fullest extent permitted by the WBCA, indemnify the officers,
directors, agents and employees of InterWest with respect to expenses,
settlements, judgments and fines in suits in which such person has made a
party by reason of the fact that he or she is or was an agent of InterWest. 
No such indemnification may be given if the acts or omissions of the person
are adjudged to be in violation of law, if such person is liable to the
corporation for an unlawful distribution, or if such person personally
received a benefit to which he or she was not entitled.  In addition,
InterWest's Articles of Incorporation provide that the directors of InterWest
shall not be personally liable for monetary damages to InterWest for certain
breaches of their fiduciary duty as directors, except for liabilities that
involve intentional misconduct by the director, the authorization or illegal
distributions or receipt of an improper personal benefit from their actions as
directors.  This provision might, in certain instances, discourage or deter
shareholders or management from bringing a lawsuit against directors for a
breach of their duties even though such an action, if successful, might have
benefitted InterWest.    

     Central.  Pursuant to Central's Articles of Incorporation, Central will
indemnify the directors and officer-directors of Central for judgments,
penalties, fines, settlements and reasonable expenses in suits in which such
person has made a party by reason of the fact that such person is or was a
director or officer- director of Central.  No such indemnification may be
given if the acts or omissions of the person are adjudged to involve
intentional misconduct or a knowing violation of law by the director, conduct
violating Section 23A.08.450 of the Revised Code of Washington or
participation in any transaction from which the director personally received a
benefit to which the director was not legally entitled.  In addition,
Central's Articles of Incorporation provides that the directors and 
<PAGE>
officer-directors of Central shall not be personally liable for monetary
damages to Central for conduct as directors or officer-directors, except for
liabilities that involve intentional misconduct or a knowing violation of law
by the director, conduct violating Section 23A.08.450 of the Revised Code of
Washington or participation in any transaction from which the director
personally received a benefit to which the director was not legally entitled.  
Amendment of Articles of Incorporation and Bylaws.  

     InterWest.  InterWest's Articles of Incorporation may be amended by the
vote of the holders of a majority of the outstanding shares of InterWest
Common Stock, except that the provisions of the Articles of Incorporation
governing approval of business combinations with "Related Persons" may not be
amended, altered, changed or repeated except by the vote of the holders of at
least 80% of the outstanding shares of InterWest, unless any such amendment
has been approved by a majority of the members of the InterWest Board who were
directors prior to the time any Related Person became a Related Person.  The
Bylaws of InterWest may be amended by a majority vote of the Board of
Directors or by the holders of at least a majority of the outstanding shares
of InterWest.  

     Central.   Central's Articles of Incorporation may be amended by a
majority of the outstanding shares of Central Common Stock, except that
provisions of Central's Articles of Incorporation relating to business
combinations with "Control Persons" may not be repealed or amended except by
the affirmative vote of two- thirds of the outstanding shares of Central
Common Stock, or if there is a Control Person, by two-thirds of the total
shares attributable to shares owned by persons other than Control Persons. 
Central's Bylaws may be amended, altered or repealed at any regular meeting of
the Central Board provided that two days prior written notice of such action
is provided.

                  ELECTION OF CENTRAL DIRECTORS

     In addition to approving the Merger, Central's stockholders will be asked
to elect two directors to serve for a three year term or until their
successors are elected and qualified.   

General

     Central's Articles of Incorporation (the "Central Articles") provide that
the number of directors must fall within a range of five and eighteen, the
exact number to be determined by resolution of the Central Board.  The Central
Articles also provide that the Central Board may increase the number of
directors by not more than three between shareholders' meetings, and may fill
the vacancies created by doing so, provided that the number of directors shall
at no time exceed eighteen.

     Directors are elected for a term of three years and until their
successors have been elected and qualified.  The Central Articles require that
the terms of the directors be staggered such that approximately one-third of
the directors are elected each year.  Accordingly, the Central Board has
nominated Messrs. DeCamp and Cawdery for election as directors for three-year
terms to expire in 1999.  If either Messrs. DeCamp or Cawdery should refuse or
be unable to serve, proxies will be voted for such person as shall be
designated by the Central Board to replace any such nominee.  The Central
Board presently has no knowledge that any of the nominees will refuse or be
unable to serve. 

     Other nominations, if any, may be made only in accordance with the prior
notice provisions contained in the Central Articles.  
<PAGE>

Certain Committees of the Board of Directors

     The Central Board has established certain standing committees, including
an Audit Committee and a Compensation Committee.  There is presently no
standing nominating committee.

     Audit Committee.  The main functions performed by the Audit Committee
include reviewing and approving the services of the independent auditors,
reviewing the plan, scope, and audit results of the independent auditors and
reviewing the reports of bank regulatory authorities.  The Committee reviews
the results of the audit, the annual reports to the Securities and Exchange
Commission and to the shareholders and the Annual Meeting Proxy Statement. 
Current members of the Committee are Messrs. Carlson, Cordell and DeCamp
(Chairman).  There were four meetings of the Audit Committee during 1995.

     Compensation Committee.  The Compensation Committee reviews and
recommends
compensation for senior management.  Current members of the Committee are
Messrs. Cawdery (Chairman) and Liddell and Ms. Guderian.  There were two
meetings of the Compensation Committee during 1995.

Compensation of Directors

     Members of the Central Board, the Audit and the Compensation Committees
currently receive fees for each meeting they attend, unless a Board or
committee meeting is held jointly with a Central or CWB Board or committee
meeting, as follows:

     1.  Board Meetings -- Directors receive $200 for each meeting attended,
except the Chairman, who receives $300 for each meeting attended.

     2.  Audit Committee and/or Compensation Committee -- The Chairmen receive
$125 for each meeting attended; other members receive $75 for each meeting
attended.

     Deferred Compensation Agreements.  CWB has entered into Deferred
Compensation Agreements with six (6) of CWB's directors which allow the
directors, at their option, to defer regular monthly bank Board and Executive
Committee fees to be paid upon retirement or termination of the Agreements. 
Under the terms of the Agreements, CWB agrees to pay the deferred amount plus
interest at retirement over a ten year period. CWB has purchased insurance
policies on the lives of these directors as a vehicle to fund the benefits
payable under the Agreements.

(1)  On December 31, 1995, the closing price of Central common
stock was $23.00.  For purposes of the foregoing table, stock
options with an exercise price less than that amount are considered
to be "in-the-money" and are considered to have a value equal to
the difference between this amount and the exercise price of the
stock option multiplied by the number of shares covered by the
stock option.

     Deferred Compensation and Change in Control Agreements.  In
August, 1989, Central entered into an Executive Deferred
Compensation Agreement (the "Deferred Compensation Agreement") with
Gary M. Bolyard, who, for both Central and CWB, is President, CEO
and a director.  The Deferred Compensation Agreement provides Mr.
Bolyard with certain deferred payments, in consideration of his
services to Central and CWB and his contribution to their growth
and progress.  Upon a "Retirement Date" of January 1, 2001, death
or termination in connection with a disability or change in control
of Central, Mr. Bolyard is entitled to receive $57,365 annually
from the date of such event (as such date is defined in the
Deferred Compensation Agreement) for a period of 15 years.  If Mr.
Bolyard's employment is terminated prior to the Retirement Date,
Mr. Bolyard is entitled to prorated payments for a 15 year period 
from the date of termination, based on length of service between
April 1989, and the Retirement Date.  In connection with his
obligations under the Deferred Compensation Agreement, Central has
obtained an insurance policy on the life of Mr. Bolyard in the face
amount of $500,000 which was purchased to offset future payments
which may be made under the Deferred Compensation Agreement.

     In June, 1995, Central entered into an Executive Deferred
Compensation Agreement (the "Deferred Compensation Agreement") with
Joseph E. Riordan, who is Treasurer/Assistant Secretary of Central,
Vice President and Secretary/Treasurer of CWB, and Assistant
Secretary/Treasurer of NCWB.  The Deferred Compensation Agreement
provides Mr. Riordan with certain deferred payments, in
consideration of his services to CWB and Central and his
contribution to their growth and progress.  Upon a "Retirement 
Date" (any date after June 30, 2009), death, or termination in
connection with a disability, Mr. Riordan is entitled to receive
benefits in fifteen equal annual installments consisting of
principal and interest (at eight percent) sufficient in amount to
pay full Executive's Vested Deferred Compensation Balance.  If Mr.
Riordan's employment is terminated prior to the Retirement Date,
Mr. Riordan is entitled to prorated payments for a 15-year period
from the date of termination, based on length of service between
June 1995 and the Retirement Date.  In connection with its
obligation under the Deferred Compensation Agreement, Central has
obtained an insurance policy on the life of Mr. Riordan with a face
amount of $225,000 which was purchased to offset future payments
which may be made under the Deferred Compensation Agreement.

     In May, 1990, Central entered into an Executive Severance
Agreement with Mr. Riordan to ensure that the Executive will be
available to assist the Central Board in responding to and, if
deemed appropriate by the Central Board, completing any proposed
change in control of Central.  Under the terms of the agreement, in
the event of the voluntary or involuntary termination of
Executive's employment within three years after a change in
control, the severance payment shall be an amount equal to the
lesser of two (2) times the compensation received by the Executive
during the most recent twelve calendar months or $114,000.  The
agreement was subsequently amended in January 1991 and January
1995.

     In March, 1993, Central entered into an Executive Severance
Agreement with Mr. Southwick, CWB's Vice President and Chief 
Lending Officer to ensure that the Executive will be available to
assist the Central Board in responding to and, if deemed
appropriate by the Central Board, completing any proposed change in
control of Central.  Under the terms of the agreement, in the event
of the voluntary or involuntary termination of Executive's
employment within three years after a change in control, the
severance payment shall be an amount equal to the lesser of one (1)
times the compensation received by the Executive during the most
recent twelve calendar months or $62,500.

     In April, 1993, Central entered into an Executive Severance
Agreement with Ms. Chase, Central's Vice President of Operations to
ensure that the Executive will be available to assist the Central
Board in responding to and, if deemed appropriate by the Central
Board, completing any proposed change in control of Central.  Under
the terms of the agreement, in the event of the voluntary or
involuntary termination of the Executive's employment within three
years after a change in control, the severance payment shall be an
amount equal to the lesser of one (1) times the compensation
received by the Executive during the most recent twelve calendar
months or $42,500.

     Description of Employee and Director Profit and Incentive
Plans.  Central has instituted and maintains an incentive
compensation plan for key employees and directors, as well as a
401(k) plan for its employees.

          Incentive Compensation Plan ("ICP") was adopted in 1987
and is a voluntary incentive plan for eligible persons deemed to be
"key employees" of Central.  Under the ICP, participants receive
additional compensation based on Central's level of profitability.
The amount of compensation provided under the ICP is calculated as
the ratio of Central's net income (excluding extraordinary income
and expense), before accrual of amounts under the ICP, as adjusted
for taxes ("Net Income") to Central's beginning equity.  In 1995,
$264,000 was accrued under the ICP.

          Directors' Incentive Compensation Plan ("Directors' ICP")
was adopted in 1990.  Under the Directors' ICP, Directors are
entitled to an increase in their director fees based on the same
ratio of Net Income to beginning equity.  In 1995, $21,000 was
accrued under the Directors' ICP.

          401(k) Savings and Profit Sharing Plan ("401(k) Plan")
was adopted on July 1, 1987 and designed to qualify under Sections
401(a) and 401(k) of the Internal Revenue Code.  All full-time
employees of Central who have been continuously employed for one
year may elect to participate in the 401(k) Plan by directing the
deferral of between 2% to 10% of their regular pay ("Employee
Deferrals").  Under the 401(k) Plan, Central will contribute $.50
for each $1.00 of Employee Deferrals, up to 3% of an employee's
annual gross salary ("Matching Funds").  Also under the 401(k)
Plan, Central, at its discretion, may contribute an additional
amount determined by Central's Board of Directors based on the
Bank's profits.  For 1995, the Board determined not to make any
additional contributions pursuant to the 401(k) Plan.  In 1995,
$69,000 was paid under the 401(k) Plan's matching funds provision.

     All funds in the 401(k) Plan are held by Fidelity Advisor.
Participants in the 401(k) Plan may direct the investment of their
Employee Deferrals in either or any of five funds:  an income fund,
consisting of equity and bond investments; a short-term fixed
income bond fund; a growth fund consisting of equity investments;
a money fund consisting of U.S. Treasury bonds; and an overseas
fund consisting of international equity and bond investments.

     Upon retirement or termination of employment, a participant is
entitled to receive all of his or her Employee Deferrals.  The
participant also will be eligible to withdraw Matching Funds and,
subject to a vesting schedule, any amounts contributed by Central. 
A participant becomes fully vested in five years, with vesting of
25% each year after the first year of participation.

     Description of Stock Option Plans.  Central maintains a stock
option plan for both employees and nonemployee directors.  Each
plan is administered by a committee appointed by the Board of
Directors.

          Employee Stock Option Plan (the "ESOP") was adopted by
the Board of Directors and approved by the shareholders in 1992. 
The ESOP replaced the Incentive Stock Option Plan adopted in 1986
("1986 Plan").  However, options for 34,686 shares of Common Stock
previously granted under the 1986 Plan remain outstanding.

     The ESOP provides for the issuance of options which qualify as
"incentive stock options" within the meaning of Section 422A of the
Internal Revenue Code, as well as the issuance of nonqualified
stock options. Subject to some exceptions, holders of incentive
stock options generally incur no tax (and Central is not entitled
to a deduction) on the grant or exercise of such options.  When
stock received upon exercise of an incentive stock option is sold,
the holder incurs tax at capital gain rates.  In order to qualify
under Section 422A, incentive stock options are subject to a number
of restrictions, including the following:  (i) the option price may
not be less than the fair market value of the stock at the time the
option is granted, (ii) the market value of the stock for which an
employee's incentive stock options become exercisable in any year
may not exceed $100,000.  All options granted under the ESOP must
be exercised within ten years from the date of grant.

     The holder of a nonqualified stock option incurs a tax on the
date of exercise of such option.  The holder is taxed on the
difference between the fair market value of the stock subject to
the option, measured at the date of grant and the date of exercise. 
The income is taxable at ordinary income rates and is deductible by
Central.  The exercise price of nonqualified options is granted
under the ESOP may be at or below market price.

      As of December 31, 1995, the ESOP had 60,000 shares reserved
for issuance, of which none had been issued pursuant to option
exercises, 22,150 were granted subject to outstanding options, and
37,850 remained available for future grant.

          Directors Stock Option Plan ("DSOP Plan") was adopted by
the Directors and Shareholders in 1995.  Under the DSOP Plan,
60,000 shares of Common Stock are reserved for issuance upon the
exercise of nonqualified stock options granted to non-employee
directors of Central and the Banks.  The DSOP Plan provides that
the exercise price of options granted must be not less than the
greater of book value or market value at the time of grant. Each
option granted under the DSOP Plan expires ten years following the
date of grant.  As of December 31, 1995, no shares had been issued
pursuant to option exercises, 40,000 were granted subject to
outstanding options, and 20,000 remained available for future
grant.

Compliance with Section 16(a) of the Securities Exchange Act

     Central has adopted procedures to assist its directors and
executive officers with Section 16(a) of the Securities Exchange
Act, which includes assisting the officer or director in preparing
forms for filing.  Based on the review of such forms, Central
believes that all of its executive officers and directors complied
with all filing requirements applicable to them.

Certain Transactions

     During 1995, many directors and executive officers of Central
and the Banks and their associates were also customers of the
Banks.  It is anticipated that directors, executive officers, and
their associates will continue to be customers of the Banks in the
future.  All transactions between the Banks and directors,
executive officers, and their associates were made in the ordinary
course of business on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for
comparable transactions with other persons and in the opinion of
management did not involve more than the normal risk of
collectibility or present other unfavorable features.

     The law firm of Carlson Drewelow & McMahon, Inc. PS, of which
director Larry Carlson is a partner, serves as counsel to Central
and the Banks on various legal matters.

Security Ownership of Certain Beneficial Owners and Management

     The following table sets forth certain information concerning
executive officers of Central and the Banks (other than those who
also serve as a director), as well as the beneficial owners of more
than five percent of the outstanding shares of Central.  The
information includes the number of shares of Central common stock
beneficially owned by each individual on January 1, 1996 and the
percentage outstanding on that date that the individual's holdings
represented.  Where beneficial ownership was less than one percent,
the percentage is not reflected in the table.

provisions of this Plan, on the Effective Date:

     (A)  OUTSTANDING INTERWEST COMMON STOCK.  The shares of InterWest
Common Stock issued and outstanding immediately prior to the Effective Date
shall, on and after the Effective Date, remain as issued and outstanding
shares of InterWest Common Stock. 

     (B)  OUTSTANDING COMPANY COMMON STOCK.  Each share of Eligible
Company Common Stock issued and outstanding immediately prior to the Effective
Date shall, by virtue of the Corporate Merger, automatically and without any
action on the part of the holder thereof, become and be converted into the
right to receive 1.7 shares of InterWest Common Stock  (as subject to
adjustment pursuant to this paragraph, the "Exchange Ratio"); provided,
however, that (1) in the event that the InterWest Price is greater than the
Collar Price and no Triggering Event has occurred, then each share of Eligible
Company Common Stock issued and outstanding immediately prior to the Effective
Date shall become and be converted into the right to receive the greater of:
(i) 1.41 shares of InterWest Common Stock or (ii) that number of shares of
InterWest Common Stock obtained by dividing the Total Consideration by the
InterWest Price, and by further dividing the quotient so reached by the
aggregate number of all shares of Eligible Company Common Stock issued and
outstanding immediately prior to the Effective Date and (2) in the event that
the InterWest Price is greater than the Collar Price and a Triggering Event
has occurred, then each share of Eligible Company Common Stock issued and
outstanding immediately prior to the Effective Date shall become and be
converted into the right to receive the greater of:  (i) 1.41 shares of
InterWest Common Stock or (ii) that number of shares of InterWest Common Stock
obtained by dividing the Total Consideration by the Pre-Triggering Event
InterWest Price, and by further dividing the quotient so reached by the
aggregate number of all shares of Eligible Company Common Stock issued and
outstanding immediately prior to the Effective Date.

     2.2. STOCKHOLDER RIGHTS; STOCK TRANSFERS.  On the Effective Date,
holders of Company Common Stock shall cease to be, and shall have no rights
as, stockholders of the Company, other than to receive the consideration
provided under this Article II.  After the Effective Date, there shall be no
transfers on the stock transfer books of the Company or the Continuing
Corporation of the shares of Company Common Stock which were issued and
outstanding immediately prior to the Effective Date.

     2.3. FRACTIONAL SHARES.  Notwithstanding any other provision hereof, no
fractional shares of InterWest Common Stock and no certificates or scrip
therefor, or other evidence of ownership thereof, will be issued in the
Corporate Merger; instead, InterWest shall pay to each holder of Company
Common Stock who would otherwise be entitled to a fractional share an amount
in cash determined by multiplying such fraction by the InterWest Price. 

     2.4. EXCHANGE PROCEDURES.  As promptly as practicable after the Effective
Date, InterWest shall send or cause to be sent to each former stockholder of
the Company of record immediately prior to the 
<PAGE>
Effective Date transmittal materials for use in exchanging such stockholder's
certificates for Company Common Stock for the consideration set forth in this
Article II.  The certificates representing the shares of InterWest Common
Stock into which shares of such stockholder's Company Common Stock are
converted on the Effective Date, any fractional share checks which such
stockholder shall be entitled to receive, and any dividends paid on such
shares of InterWest Common Stock for which the record date for determination
of stockholders entitled to such dividends is on or after the Effective Date,
will be delivered to such stockholder only upon delivery to InterWest Savings
(the "Exchange Agent") of the certificates representing all of such shares of
Company Common Stock (or indemnity satisfactory to InterWest and the Exchange
Agent, in their judgment, if any of such certificates are lost, stolen or
destroyed).  No interest will be paid on any such fractional share checks or
dividends to which the holder of such shares shall be entitled to receive upon
such delivery.  Certificates surrendered for exchange by any person
constituting an "affiliate" of the Company for purposes of Rule 145 of the
Securities Act shall not be exchanged for certificates representing InterWest
Common Stock until InterWest has received a written agreement from such person
as specified in Section 5.10.

     2.5. ANTI-DILUTION PROVISIONS.  In the event InterWest changes the number
of shares of InterWest Common Stock issued and outstanding prior to the
Effective Date as a result of a stock split, stock dividend, recapitalization
or similar transaction with respect to the outstanding InterWest Common Stock
and the record date therefor shall be prior to the Effective Date, the
Exchange Ratio shall be proportionately adjusted.

     2.6. EXCEPTION SHARES.  Each of the Exception Shares of Company Common
Stock shall be canceled and retired at the effectiveness of the Corporate
Merger and no consideration shall be issued in exchange therefor.

     2.7. RESERVATION OF RIGHT TO REVISE TRANSACTION.  InterWest may at
any time change the method of effecting the acquisition of the Company and the
Banks by InterWest (including the provisions of this Article II) if and to the
extent it deems such change to be desirable; provided, however, that no such
change shall (i) alter or change the amount or kind of consideration to be
issued to holders of Company Common Stock as provided for in this Plan or (ii)
adversely affect the tax treatment to the Company stockholders as a result of
receiving such consideration.

     2.8. OPTIONS.  On the Effective Date, by virtue of the Corporate Merger,
and without any action on the part of any holder of an option, each option
granted by the Company to purchase shares of Company Common Stock ("Company
Option") that is then outstanding and unexercised shall be converted into and
become an option to purchase InterWest Common Stock ("InterWest Option") on
the same terms and conditions as are in effect with respect to the Company
Option immediately prior to the Effective Date, except that (i) each such
InterWest Option may be exercised solely for shares of InterWest Common Stock,
(ii) the number of shares of InterWest Common Stock subject to such InterWest
Option shall be equal to the number of shares of Company Common Stock subject
to such Option immediately prior to the Effective Date multiplied by the
Exchange Ratio, the product being rounded, if necessary, up or down to the
nearest whole share, and (iii) the per share exercise price under each such
InterWest Option shall be adjusted by dividing the per share exercise price of
the Company Option by the Exchange Ratio, and rounding up to the nearest cent. 
The number of shares of Company Common Stock which are issuable upon exercise
of Options as of the date hereof are Previously Disclosed in Schedule 2.8. 
Following the Effective Date, InterWest shall use its best efforts to prepare
and file with the SEC a registration statement on Form S-8 covering shares of
InterWest Common Stock to be issued upon the exercise of stock options assumed
by InterWest pursuant to this Section 2.8.

     (B)  ORGANIZATION, STANDING AND AUTHORITY.  Each of the Company

to have a Material Adverse Effect on it.  Each of the Company and its
Subsidiaries has in effect all federal state, local, and foreign governmental
authorizations necessary for it to own or lease its properties and assets and
to carry on its business as it is now conducted, the absence of which,
individually or in the aggregate, is reasonably likely to have a Material
Adverse Effect on it.

     (C)  SHARES.  The outstanding shares of the Company and its Subsidiaries'
capital stock are validly issued and outstanding, fully paid and
nonassessable, and subject to no preemptive rights.  Except as Previously
Disclosed in Schedule 4.1(C), there are no shares of capital stock or other
equity securities of the Company or its Subsidiaries outstanding and no
outstanding Rights with respect thereto (except as provided under the Stock

commitments, understandings or arrangements by which any of its Subsidiaries
is or may be bound to sell or otherwise issue any shares of such Subsidiary's
capital stock, and there are no contracts, commitments, understandings or
arrangements relating to the rights of the Company or its Subsidiaries, as

capital stock of each of its Subsidiaries held by the Company or one of its
Subsidiaries are fully paid and nonassessable and are owned by the Company or
one of its Subsidiaries free and clear of any charge, mortgage, pledge,
security interest, restriction, claim, lien or encumbrance (except for the
lien that encumbers CWB Common Stock and secures a loan to the Company from
Key Bank of Washington). Each of its Subsidiaries is in good standing under
the laws of the jurisdiction in which it is incorporated or organized, and is
duly qualified to do business and in good standing in the jurisdictions where
the failure to be duly qualified is reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on it.  Except as Previously
Disclosed in Schedule 4.1(D), it does not own beneficially, directly or
indirectly, any shares of any equity securities or similar interests of any
corporation, bank, partnership, joint venture, business trust, association or
other organization.  In the case of representations by the Company, the

Fund of the FDIC.

enforceable against the Company and such Subsidiaries in accordance with its
terms, subject to bankruptcy, insolvency and other laws of general
applicability relating to or affecting creditors' rights and to general equity
principles.

     (G)  NO DEFAULTS.  Subject to the approval by its shareholders referred
to in Section 6.1, the required regulatory approvals referred to in Section
6.1, and the required filings under federal and state securities laws, and

performance of this Plan and the Stock Option Agreement, and the consummation

Adverse Effect on it, (ii) constitute a breach or violation of, or a default

rule, regulation, judgment, decree, order, governmental permit or license or
the consent or approval of any other party to any such agreement, indenture or

Company Financial Reports, the "Financial Reports") did not and will not

fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances under which they were made, not
misleading; and each of the balance sheets in or incorporated by reference
into the Financial Reports (including the related notes and schedules thereto)
fairly presents and will fairly present the financial position of the entity
or entities to which it relates as of its date, and each of the statements of
income and changes in stockholders' equity and cash flows or equivalent
statements in the Bank Financial Reports (including any related notes and
schedules thereto) fairly presents and will fairly present the results of
operations, changes in stockholders' equity and cash flows, as the case may
be, of the entity or entities to which it relates for the periods set forth

     (I)  ABSENCE OF UNDISCLOSED LIABILITIES.  Neither the Company nor any
of its Subsidiaries has any obligation or liability (contingent or otherwise)

Material Adverse Effect on it, except  (i) as reflected in its Holding Company
Financial Reports prior to the date of this Plan and (ii) for commitments and
obligations made, or liabilities incurred, in the ordinary course of business
consistent with past practice since December 31, 1994.   Since December 31,
1994, neither the Company nor any of its Subsidiaries has incurred or paid any
obligation or liability (including any obligation or liability incurred in
connection with any acquisitions in which any form of direct financial
assistance of the federal government or any agency thereof has been provided
to any Subsidiary) which, individually or in the aggregate, is reasonably
likely to have a Material Adverse Effect on it. 
     
     (J)  NO EVENTS.  Except as Previously Disclosed on Schedule 4.1(J), since

defaults, or equities of any character, to all of the properties and assets,
tangible and intangible, reflected in its Holding Company Financial Reports as
being owned by the Company or its Subsidiaries as of the dates thereof other
than those that, individually or in the aggregate, are not reasonably likely
to have a Material Adverse Effect on it, except those sold or otherwise
disposed of in the ordinary course of business.  All buildings and all
material fixtures, equipment, and other property and assets that are held
under leases or subleases by the Company or any of its Subsidiaries are held
under valid leases or subleases enforceable in accordance with their
respective terms, other than any such exceptions to validity or enforceability
that, individually or in the aggregate, are not reasonably likely to have a
Material Adverse Effect on it.

     (L)  LITIGATION; REGULATORY ACTION.  Except as Previously Disclosed in
Schedule 4.1(L), no litigation, proceeding or controversy before any court or
governmental agency is pending that, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect on the Company or any of
its Subsidiaries or that alleges claims under any fair lending law or other
law relating to discrimination, including the Equal Credit Opportunity Act,
the Fair Housing Act, the Community Reinvestment Act and the Home Mortgage
Disclosure Act, and, to the best of its knowledge, no such litigation,
proceeding or controversy has been threatened; and except as Previously
Disclosed in Schedule 4.1(L), neither the Company nor any of its Subsidiaries
or any of its or their material properties or their officers, directors or
controlling persons is a party to or is subject to any order, decree,

neither the Company nor any of its Subsidiaries has been advised by any of
such Regulatory Authorities that such authority is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting)
any such order, decree, agreement, memorandum or understanding, commitment
letter or similar submission. 


     (M)  COMPLIANCE WITH LAWS.  Except as Previously Disclosed in Schedule
4.1(M), each of the Company and its Subsidiaries: 

(1)  has all permits, licenses, authorizations, orders and approvals of, and
has made all filings, applications and registrations with, all Regulatory
Authorities that are required in order to permit it to own its businesses
presently conducted and that are material to the business of it and its
Subsidiaries taken as a whole; all such permits, licenses, certificates of
authority, orders and approvals are in full force and effect and, to its best
knowledge, no suspension or cancellation of any of them is threatened; and all
such filings, applications and registrations are current; 

(2)  has received no notification or communication from any Regulatory
Authority or the staff thereof (i) asserting that the Company or any of its
Subsidiaries is not in compliance with any of the statutes, regulations or

such
noncompliance in any such instance, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect on the Company or its
Subsidiaries, (ii) threatening to revoke any license, franchise, permit or
governmental authorization, which revocation, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect on the
Company or its Subsidiaries, or (iii) requiring any of the Company or its

<PAGE>

     (N)  MATERIAL CONTRACTS.  Except as Previously Disclosed in Schedule
4.1(N), none of the Company or its Subsidiaries, nor any of its respective
assets, businesses or operations, is a party to, or is bound or affected by,
or receives benefits under, any contract or agreement or amendment thereto
that in each case would be required to be filed as an exhibit to a Form 10-K
filed by the Company that has not been filed as an exhibit to the Company's
Form 10-K filed for the fiscal year ended December 31, 1994.  Neither the
Company nor any of its Subsidiaries is in default under any contract,
agreement, commitment, arrangement, lease, insurance policy or other
instrument to which it is a party, by which its respective assets, business or
operations may be bound or affected, or under which it or any of its
respective assets, business or operations receives benefits, which default,
individually or in the aggregate, is reasonably likely to have a Material
Adverse Effect on the Company or its Subsidiaries, and there has not occurred
any event that, with the lapse of time or the giving of notice or both, would
constitute such a default.  Except as Previously Disclosed in Schedule 4.1(N),
neither the Company nor any of its Subsidiaries is subject to or bound by any
contract containing covenants which limit the ability of the Company or any of
its Subsidiaries to compete in any line of business or with any person or
which involve any restriction of geographical area in which, or method by
which, the Company or any of its Subsidiaries may carry on its business (other
than as may be required by law or any applicable Regulatory Authority).

     (O)  REPORTS.  Since January 1, 1991, each of the Company and its
Subsidiaries has filed all reports and statements, together with any
amendments required to be made with respect thereto, that it was required to
file with (i) the FDIC, (ii) the Department, (iii) the Federal Home Loan Bank
and the Federal Home Loan Bank System, and (iv) any other applicable
Regulatory Authorities.  As of their respective dates (and without giving
effect to any amendments or modifications filed after the date of this Plan
with respect to reports and documents filed before the date of this Plan),
each of such reports and documents, including the financial statements,
exhibits and schedules thereto, complied in all material respects with all of
the statutes, rules and regulations enforced or promulgated by the Regulatory
Authority with which they were filed and did not contain any untrue statement
of a material fact or omit to state any material fact necessary in order to
make the statements made therein, in light of the circumstances under which
they were made, not misleading.

     (P)  NO BROKERS.  All negotiations relative to this Plan and the
transactions contemplated hereby have been carried on by it directly with the
other Parties and no action has been taken by it that would give rise to any
valid claim against any Party for a brokerage commission, finder's fee or
other like payment (except for a fee to be paid by the Company to Columbia
Financial Advisors, Inc.).

     (Q)  EMPLOYEE BENEFIT PLANS.

(1)  Schedule 4.1(Q)(1) contains a complete list of all bonus, deferred
compensation, pension, retirement, profit-sharing, thrift savings, employee
stock ownership, stock bonus, stock purchase restricted stock and stock option
plans, all employment or severance contracts, all medical, dental, health and
life insurance plans, all other employee benefit plans, contracts or
arrangements and any applicable "change of control" or similar provisions in
any plan, contract or arrangement maintained or contributed to by the Company
or any of its Subsidiaries for the benefit of employees, former employees,
directors, former directors or their beneficiaries (the "Compensation and
Benefit Plans").  True and complete copies of all Compensation and Benefit
Plans of the Company and its Subsidiaries, including any trust instruments
and/or insurance contracts, if any, forming a part thereof, and all amendments
thereto, have been supplied to the other Parties.

(2)  All "employee benefit plans" within the meaning of Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), other
than "multiemployer plans" within the meaning of Section 3(37) of ERISA
("Multiemployer Plans"), covering employees or former employees of the Company
and its Subsidiaries (the "ERISA Plans"), to the extent subject to ERISA, are
in substantial compliance with ERISA.  Except as Previously Disclosed in
Schedule 4.1(Q)(2), each ERISA Plan which is an "employee pension benefit
plan" within the meaning of Section 3(2) of ERISA ("Pension Plan") and which
is intended to be qualified under Section 401(a) of the Internal Revenue Code
of 1986 (as amended, the "Code") has received a favorable determination letter
from the Internal Revenue Service, and it is not aware of any circumstances
reasonably likely to result in the revocation or 
<PAGE>
denial of any such favorable determination letter or the inability to receive
such a favorable determination letter.  There is no material pending or, to
its knowledge, threatened litigation relating to the ERISA Plans.  Neither the
Company nor any of its Subsidiaries has engaged in a transaction with respect
to any ERISA Plan that could subject the Company or any of its Subsidiaries to
a tax or penalty imposed by either Section 4975 of the Code or Section 502(i)
of ERISA in an amount which would be material.

(3)  No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by the Company or any of its Subsidiaries with respect
to any ongoing, frozen or terminated "single-employer plan," within the
meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by
any of them, or the single-employer plan of any entity which is considered one
employer with the Company under Section 4001(a)(15) of ERISA or Section 414 of
the Code (an "ERISA Affiliate").  Neither the Company nor any of its
Subsidiaries presently contributes to a Multiemployer Plan, nor have they
contributed to such a plan within the past five calendar years.  No notice of
a "reportable event," within the meaning of Section 4043 of ERISA for which
the 30-day reporting requirement has not been waived, has been required to be
filed for any Pension Plan or by any ERISA Affiliate within the past 12-month
period.

(4)  All contributions required to be made under the terms of any ERISA Plan
have been timely made.  Neither any Pension Plan nor any single-employer plan
of an ERISA Affiliate has an "accumulated funding deficiency" (whether or not
waived) within the meaning of Section 412 of the Code or Section 302 of ERISA. 
Neither the Company nor any of its Subsidiaries has provided, or is required
to provide, security to any Pension Plan or to any single-employer plan of an
ERISA Affiliate pursuant to Section 401(a)(29) of the Code.

(5)  Under each Pension Plan which is a single-employer plan, as of the last
day of the most recent plan year, the actuarially determined present value of
all "benefit liabilities," within the meaning of Section 4001(a)(16) of ERISA
(as determined on the basis of the actuarial assumptions contained in the
plan's most recent actuarial valuation) did not exceed the then current value
of the assets of such plan, and there has been no material change in the
financial condition of such plan since the last day of the most recent plan
year. 

(6)  Neither the Company nor any of its Subsidiaries has any obligations for
retiree health and life benefits under any plan, except as set forth in
Schedule 4.1(Q)(6).  There are no restrictions on the rights of the Company or
any of its Subsidiaries to amend or terminate any such plan without incurring
any liability thereunder.

(7)  Except as Previously Disclosed in Schedule 4.1(Q)(7), neither the
execution and delivery of this Plan nor the consummation of the transactions
contemplated hereby will (i) result in any payment (including severance,
unemployment compensation, golden parachute or otherwise) becoming due to any
director or any employee of the Company or any of its Subsidiaries under any
Compensation and Benefit Plan or otherwise from the Company or any of its
Subsidiaries, (ii) increase any benefits otherwise payable under any
Compensation and Benefit Plan, or (iii) result in any acceleration of the time
of payment or vesting of any such benefit.

     (R)  NO KNOWLEDGE.  The Company and its Subsidiaries know of no reason
why the regulatory approvals referred to in Section 6.2 should not be
obtained.

     (S)  LABOR AGREEMENTS.  Neither the Company nor any of its Subsidiaries
is a party to or is bound by any collective bargaining agreement, contract or
other agreement or understanding with a labor union or labor organization, nor
is the Company or any of its Subsidiaries the subject of a proceeding
asserting that it or any such Subsidiary has committed an unfair labor
practice (within the meaning of the National Labor Relations Act) or seeking
to compel it or such Subsidiary to bargain with any labor organization as to
wages and conditions of employment, nor is there any strike or other labor
dispute involving it or any of its Subsidiaries, pending or, to the best of
its knowledge, threatened, nor is it aware of any activity involving its or
any of the 
<PAGE>
Subsidiaries' employees seeking to certify a collective bargaining unit or
engaging in any other organization activity.

     (T)  ASSET CLASSIFICATION.  The Company and its Subsidiaries have
Previously Disclosed in Schedule 4.1(T) a list, accurate and complete in all
material respects, of the aggregate amounts of loans, extensions of credit or
other assets of the Company and its Subsidiaries that have been classified by
it as of December 31, 1995 (the "Asset Classification"); and no amounts of
loans, extensions of credit or other assets that have been classified as of
December 31, 1995 by any regulatory examiner as "Other Loans Specially
Mentioned," "Substandard," "Doubtful" "Loss," or words of similar import are
excluded from the amounts disclosed in the Asset Classification, other than
amounts of loans, extensions of credit or other assets that were charged off
by the Company or any Subsidiary prior to December 31, 1995.

     (U)  ALLOWANCE FOR POSSIBLE LOAN LOSSES.  The allowance for possible
loan losses shown on the consolidated balance sheets in the December 31, 1994
Holding Company Financial Reports of the Company was, and the allowance for
possible loan losses to be shown on subsequent Holding Company Financial
Reports of the Company will be, adequate in the opinion of the Board of
Directors of the Company to provide for possible losses, net of recoveries
relating to loans previously charged off, on loans outstanding (including
accrued interest receivable) as of the date thereof.

     (V)  INSURANCE.  Each of the Company and its Subsidiaries has taken all
requisite action (including the making of claims and the giving of notices)
pursuant to its directors' and officers' liability insurance policy or
policies in order to preserve all rights thereunder with respect to all
matters that are known to the Company, except for such matters which,
individually or in the aggregate, are not reasonably likely to have a Material
Adverse Effect on the Company or its Subsidiaries.  Set forth in Schedule
4.1(V) is a list of all insurance policies maintained by or for the benefit of
the Company or its Subsidiaries or their respective directors, officers,
employees or agents.

     (W)  AFFILIATES.  Except as Previously Disclosed in Schedule 4.1(W), to
the best of the Company's knowledge, there is no person who, as of the date of
this Plan, may be deemed to be an "affiliate" of the Company as that term is
used in Rule 145 under the Securities Act.

     (X)  STATE TAKEOVER LAWS; ARTICLES OF INCORPORATION.  The
Company and its Subsidiaries have taken all necessary action to exempt this
Plan and the Stock Option Agreement and the transactions contemplated hereby
and thereby from, and this Plan and the Stock Option Agreement and the
transactions contemplated hereby and thereby are exempt from (i) any
applicable state takeover laws, including, but not limited to, RCW Ch. 23B.19,
and (ii) any takeover-related provisions of the Company's and its
Subsidiaries' Articles of Incorporation.

     (Y)  NO FURTHER ACTION.  The Company and its Subsidiaries have taken all
action so that the entering into of this Plan and the Stock Option Agreement,
and the consummation of the transactions contemplated hereby and thereby
(including the Mergers and the exercise of the Option) or any other action or
combination of actions, or any other transactions, contemplated hereby or
thereby do not and will not (i) require a vote of shareholders (other than as
set forth in Section 6.1), or (ii) result in the grant of any rights to any
person under the Articles of Incorporation, Charter or Bylaws of the Company
or any of its Subsidiaries or under any agreement to which the Company or any
such Subsidiaries is a party, or (iii) restrict or impair in any way the
ability of the other Parties to exercise the rights granted hereunder or under
the Stock Option Agreement.

     (Z)  ENVIRONMENTAL MATTERS.

(1)  To the Company's knowledge, it and each of its Subsidiaries, the
Participation Facilities and the Loan/Fiduciary Properties are, and have been,
in compliance with all Environmental Laws, except for instances of
noncompliance which are not reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on the Company or its
Subsidiaries.

(2)  There is no proceeding pending or, to the Company's knowledge, threatened

Company or any

threatened proceedings, reasonably would be expected to be, named as a
defendant or potentially responsible party (i) for alleged noncompliance
(including by any predecessor) with any Environmental Law or (ii) relating to
the release or threatened release into the environment of any Hazardous
Material, whether or not occurring at or on a site owned, leased or operated

likely, individually or in the aggregate, to have a Material Adverse Effect on
the Company or its Subsidiaries or have been Previously Disclosed in Schedule
4.1(Z)(2).

(3)  There is no proceeding pending or, to the Company's knowledge, threatened

     (A)  RECITALS.  The facts set forth in the Recitals of this Plan with
respect to InterWest and InterWest Savings are true and correct.

     (B)  ORGANIZATION, STANDING AND AUTHORITY.  Each of InterWest and
InterWest Savings is duly qualified to do business and is in good standing in

Material Adverse Effect on it.  Each of InterWest and its Subsidiaries has in
effect all federal state, local, and foreign governmental authorizations
necessary for it to own or lease its properties and assets and to carry on its
business as it is now conducted, the absence of which, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect on
InterWest.

     (C)  SHARES.  The outstanding shares of InterWest's capital stock are
validly issued and outstanding, fully paid and nonassessable, and subject to
no preemptive rights.  Except as Previously Disclosed in Schedule 4.2(C),
there are no shares of capital stock or other equity securities of it or its

thereby, does not and will not (i) constitute a breach or violation of, or a
default under, any law, rule or regulation or any judgment, decree, order,
governmental permit or license, or agreement, indenture or instrument of

to have a Material Adverse Effect on InterWest, (ii) constitute a breach or
violation of, or a default under, the Articles of Incorporation, Charter or
Bylaws of its or any of its Subsidiaries, or (iii) require any consent or
approval under any such law, rule, regulation, judgment, decree, order,
governmental permit or license or the consent or approval of any other party

Material Adverse Effect on it. 
<PAGE>
     (I)  LITIGATION; REGULATORY ACTION.  Except as Previously Disclosed in
Schedule 4.2(I), no litigation, proceeding or controversy before any court or
governmental agency is pending that, individually or in the aggregate, is

Subsidiaries or that alleges claims under any fair lending law or other law
relating to discrimination, including the Equal Credit Opportunity Act, the
Fair Housing Act, the Community Reinvestment Act and the Home Mortgage
Disclosure Act, and, to the best of its knowledge, no such litigation,
proceeding or controversy has been threatened; and except as Previously
Disclosed in Schedule 4.2(I), neither InterWest nor any of its Subsidiaries or
any of its or their material properties or their officers, directors or
controlling persons is a party to or is subject to any order, decree,
agreement, memorandum of understanding or similar arrangement with, or a
commitment letter or similar submission to, any Regulatory Authority, and
neither InterWest nor any of its Subsidiaries has been advised by any of such
Regulatory Authorities that such authority is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting)
any such order, decree, agreement, memorandum or understanding, commitment
letter or similar submission.

     (J)  REPORTS.  Since September 30, 1995, each of InterWest and its

amendments required to be made with respect thereto, that it was required to
file with (i) the FDIC, (ii) the Department, (iii) the Federal Home Loan Bank
and the Federal Home Loan Bank System, and (iii) any other applicable
Regulatory Authorities.  As of their respective dates (and without giving
effect to any amendments or modifications filed after the date of this Plan
with respect to reports and documents filed before the date of this Plan),
each of such reports and documents, including the financial statements,
exhibits and schedules thereto, complied in all material respects with all of
the statutes, rules and regulations enforced or promulgated by the Regulatory
Authority with which they were filed and did not contain any untrue statement
of a material fact or omit to state any material fact necessary in order to
make the statements made therein, in light of the circumstances under which
they were made, not misleading.

     (M)  ABSENCE OF UNDISCLOSED LIABILITIES.  Neither InterWest nor any of

information or documents become publicly available other than by reason of any
action or failure to act by InterWest or as it is advised by counsel that any
such information or document is required by law or applicable stock exchange
rule to be disclosed, and in the event of the termination of this Plan,
InterWest will, upon request by the Company, deliver to the Company all
documents so obtained by InterWest or destroy such documents and, in the case

investigation (whether arising before or after the Effective Date), (i)

substantially all of its assets to any entity, then and in each case, proper
provision shall be made so that the successors and assigns of InterWest shall
assume the obligations set forth in this Section 5.18.

under applicable Washington law.

                     STOCK OPTION AGREEMENT
<PAGE>

                     STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT, dated as of January 10, 1996 (the "Agreement"),
by and between Central Bancorporation, a Washington corporation ("Issuer"),
and InterWest Bancorp, Inc., a Washington corporation ("Grantee").

     WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Mergers dated as of January 10, 1996 (the "Plan"), providing for, among other
things, the merger of Issuer with and into Grantee, with Grantee as the
surviving corporation; and 

     WHEREAS, as a condition and inducement to Grantee's execution of the
Plan, Grantee has required that Issuer agree, and Issuer has agreed, to grant
Grantee the Option (as defined below);

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Plan, and intending to be legally bound hereby, Issuer and Grantee agree
as follows:

     1.  DEFINED TERMS.  Capitalized terms which are used but not defined
herein shall have the meanings ascribed to such terms in the Plan.

     2.  GRANT OF OPTION.  Subject to the terms and conditions set forth
herein, Issuer hereby grants to Grantee an irrevocable option (the "Option")
to purchase up to 201,898 shares (as adjusted as set forth herein, the "Option
Shares", which shall include the Option Shares before and after any transfer
of such Option Shares) of common stock, par value $1.67 per share ("Issuer
Common Stock"), of Issuer at a purchase price per Option Share (the "Purchase
Price") equal to $26.00.

     3.  EXERCISE OF OPTION.

     (a) Provided that (i) Grantee or Holder (as defined below), as
applicable, shall not be in material breach of the agreements or covenants
contained in this Agreement or the Plan, and (ii) no preliminary or permanent
injunction or other order against the delivery of shares covered by the Option
issued by any court of competent jurisdiction in the United States shall be in
effect, the Holder may exercise the Option, in whole or in part, at any time
and from time to time following the occurrence of a Purchase Event (as
hereinafter defined); PROVIDED that the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Date,
(B) termination of the Plan by Issuer in accordance with the terms thereof
prior to the occurrence of a Purchase Event or a Preliminary Purchase Event
(as hereinafter defined) (an "Issuer Termination"), (C) 15 months after the
termination of the Plan by Issuer in accordance with the terms thereof other
than pursuant to an Issuer Termination, and (D) 15 months after the
termination of the Plan by Grantee in accordance with the terms thereof;
PROVIDED,  HOWEVER, that any purchase of shares upon exercise of the Option
shall be subject to compliance with applicable law, including, without
limitation, the Bank Holding Company Act of 1956, as amended (the "BHC Act").
The term "Holder" shall mean the holder or holders of the Option from time to 
time, and which initially is Grantee.
     
     (b) As used herein, a "Purchase Event" means any of the following events:
 
     (i) Without Grantee's prior written consent, Issuer shall have
authorized, recommended, publicly proposed or publicly announced an intention
to authorize, recommend or propose, or entered into an agreement with any
person (other than Grantee or any subsidiary of Grantee) to effect an
Acquisition Transaction. As used herein, the term "Acquisition Transaction"
shall mean (A) a merger, consolidation or similar transaction involving Issuer
or any of its significant subsidiaries, (B) the disposition, by sale, lease,
exchange or otherwise, of assets or deposits of Issuer or any of its
significant subsidiaries representing in 
<PAGE>
either case 20% or more of the consolidated assets or deposits of Issuer and
its subsidiaries, or (C) the issuance, sale or other disposition of (including
by way of merger, consolidation, share exchange or any similar transaction)
securities representing 20% or more of the voting power of Issuer or any of
its significant subsidiaries other than the issuance of Issuer Common Stock
upon the exercise of outstanding options or the conversion of outstanding
convertible securities of Issuer; or

     (ii)   any person (other than Grantee or any subsidiary of Grantee) shall
have acquired beneficial ownership (as such term is defined in Rule 13d-3
promulgated under the Exchange Act) of or the right to acquire beneficial
ownership of, or any "group" (as such term is defined under the Exchange Act)
shall have been formed which beneficially owns or has the right to acquire
beneficial ownership of, 15% or more (or if such person or group is the
beneficial owner of 15% or more on the date hereof, such person or group
acquires an additional 5% or more) of the voting power of Issuer or any of its
significant subsidiaries.

     (c) As used herein, a "Preliminary Purchase Event" means any of the
following events:

         (i)  any person (other than Grantee or any subsidiary of Grantee)
shall have commenced (as such term is defined in Rule 14d-2 under the Exchange
Act) or shall have filed a registration statement under the Securities Act
with respect to, a tender offer or exchange offer to purchase any shares of
Issuer Common Stock such that, upon consummation of such offer, such person
would own or control 20% or more of the then outstanding shares of Issuer
Common Stock (such an offer being referred to herein as a "Tender Offer" or an
"Exchange Offer," respectively); or

         (ii) the holders of Issuer Common Stock shall not have approved the
Plan at the Meeting, the Meeting shall not have been held or shall have been
canceled prior to termination of the Plan, or Issuer's Board of Directors
shall have withdrawn or modified in a manner adverse to Grantee the
recommendation of Issuer's Board of Directors with respect to the Plan, in
each case after it shall have been publicly announced that any person (other
than Grantee or any subsidiary of Grantee) shall have (A) made a proposal to
engage in an Acquisition Transaction, or (B) commenced a Tender Offer or filed
a registration statement under the Securities Act with respect to an Exchange
Offer; or

         (iii) any person, other than Grantee or any subsidiary of Grantee,
shall have made a bona fide proposal to Issuer or its stockholders by public
announcement, or written communication that is or becomes the subject of
public disclosure, to engage in an Acquisition Transaction; or
        
         (iv)  after a bona fide proposal is made by a third party to Issuer
or its stockholders to engage in an Acquisition Transaction, Issuer shall have
breached any covenant or obligation contained in the Plan and such breach
would entitle Grantee to terminate the Plan under Section 7.1(b) thereof
(without regard to the cure period provided for therein unless such cure is
promptly effected without jeopardizing consummation of the Mergers pursuant to
the terms of the Plan); or

         (v)  any person, other than Grantee or any subsidiary of Grantee,
other than in connection with a transaction to which Grantee has given its
prior written consent, shall have filed an application or notice with the
Board of Governors of the Federal Reserve System (the "Federal Reserve
Board"), or other federal or state bank regulatory authority, for approval to
engage in an Acquisition Transaction.

         As used in this Agreement, "person" shall have the meaning specified
in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

     (d) Issuer shall notify Grantee promptly in writing of the occurrence of
any Preliminary Purchase Event or Purchase Event (in either case, a
"Triggering Event"), it being understood that the giving of such notice by
Issuer shall not be a condition to the right of Holder to exercise the Option.
<PAGE>

     (e) In the event Holder wishes to exercise the Option, it shall send to
Issuer a written notice (the date of which being herein referred to as the
"Notice Date") specifying (i) the total number of Option Shares it intends to
purchase pursuant to such exercise, and (ii) a place and date not earlier than
three business days nor later than 15 business days from the Notice Date for
the closing (the "Closing") of such purchase (the "Closing Date"); PROVIDED,
HOWEVER, if any required application for listing such shares on the NASDAQ
National Market System has not been approved by the date so specified, such
date shall be extended for a period not to exceed 21 days from the Notice
Date. If prior notification to or approval of the Federal Reserve Board or any
other regulatory authority is required in connection with such purchase,
Issuer shall cooperate with the Holder in the filing of the required notice of
application for approval and the obtaining of such approval and the Closing
shall occur immediately following such regulatory approvals (and any mandatory
waiting periods). Any exercise of the Option shall be deemed to occur on the
Notice Date relating thereto.

     4.  PAYMENT AND DELIVERY OF CERTIFICATES.
     
     (a) On each Closing Date, Holder shall (i) pay to Issuer, in immediately
available funds by wire transfer to a bank account designated by Issuer, an
amount equal to the Purchase Price multiplied by the number of Option Shares
to be purchased on such Closing Date, and (ii) present and surrender this
Agreement to the Issuer at the address of the Issuer specified in subsection
(f) of Section 11 hereof.

     (b) At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in subsection (a)
of this Section 4, (i) Issuer shall deliver to Holder (A) a certificate or
certificates representing the Option Shares to be purchased at such Closing,
which Option Shares shall be free and clear of all liens, claims, charges and
encumbrances of any kind whatsoever and subject to no preemptive rights, and
(B) if the Option is exercised in part only, an executed new agreement with
the same terms as this Agreement evidencing the right to purchase the balance
of the shares of Issuer Common Stock purchasable hereunder, and (ii) Holder
shall deliver to Issuer a letter agreeing that Holder shall not offer to sell
or otherwise dispose of such Option Shares in violation of applicable federal
and state law or of the provisions of this Agreement.

     (c) In addition to any other legend that is required by applicable law,
certificates for the Option Shares delivered at each Closing shall be endorsed
with a restrictive legend which shall read substantially as follows:

     THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS
SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF
___________ __, 1996. A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER
HEREOF WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A WRITTEN REQUEST
THEREFOR.
     
     It is understood and agreed that the above legend shall be removed by
delivery of substitute certificate(s) without such legend if Holder shall have
delivered to Issuer a copy of a letter from the staff of the SEC, or an
opinion of counsel in form and substance reasonably satisfactory to Issuer and
its counsel, to the effect that such legend is not required for purposes of
the Securities Act.

     (d) Upon the giving by Holder to Issuer of the written notice of exercise
of the Option provided for under subsection (e) of Section 3 hereof, the
tender of the applicable purchase price in immediately available funds and the
tender of this Agreement to Issuer, Holder shall be deemed to be the holder of
record of the shares of Issuer Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of Issuer shall then be closed
or that certificates representing such shares of Issuer Common Stock shall not
then be actually delivered to Holder. Issuer shall pay all expenses, and any
and all United States federal, state, and local taxes and other charges that
may be payable in connection with the preparation, issuance and delivery of
stock certificates under this Section in the name of Holder or its assignee,
transferee, or designee.
<PAGE>
     (e) Issuer agrees (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Issuer Common Stock so that the Option may be exercised without additional
authorization of Issuer Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Issuer Common
Stock, (ii) that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other
voluntary act, avoid or seek to avoid the observance or performance of any of
the covenants, stipulations or conditions to be observed or performed
hereunder by Issuer, (iii) promptly to take all action as may from time to
time be required (including (A) complying with all premerger notification,
reporting and waiting period requirements specified in 15 U.S.C. Section 18a
and regulations promulgated thereunder and (B) in the event, under the BHC
Act, or the Change in Bank Control Act of 1978, as amended, or a state banking
law, prior approval of or notice to the Federal Reserve Board or to any state
regulatory authority is necessary before the Option may be exercised,
cooperating fully with Holder in preparing such applications or notices and
providing such information to the Federal Reserve Board or such state
regulatory authority as they may require) in order to permit Holder to
exercise the Option and Issuer duly and effectively to issue shares of the
Issuer Common Stock pursuant hereto, and (iv) promptly to take all action
provided herein to protect the rights of Holder against dilution. 

     5.  REPRESENTATIONS AND WARRANTIES OF ISSUER.  Issuer hereby
represents and warrants to Grantee (and Holder, if different than Grantee) as
follows:

     (a) Due Authorization.  Issuer has all requisite corporate power and
authority to enter into this Agreement and, subject to any approvals or
consents referred to herein, to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by all
necessary corporate action on the part of Issuer. This Agreement has been duly
executed and delivered by Issuer.

     (b) Authorized Stock.  Issuer has taken all necessary corporate and other
action to authorize and reserve and to permit it to issue, and, at all times
from the date hereof until the obligation to deliver Issuer Common Stock upon
the exercise of the Option terminates, will have reserved for issuance, upon
exercise of the Option, the number of shares of Issuer Common Stock necessary
for Holder to exercise the Option, and Issuer will take all necessary
corporate action to authorize and reserve for issuance all additional shares
of Issuer Common Stock or other securities which may be issued pursuant to
Section 7 upon exercise of the Option. The shares of Issuer Common Stock to be
issued upon due exercise of the Option, including all additional shares of
Issuer Common Stock or other securities which may be issuable pursuant to
Section 7, upon issuance pursuant hereto, shall be duly and validly issued,
fully paid and nonassessable, and shall be delivered free and clear of all
liens, claims, charges and encumbrances of any kind or nature whatsoever,
including any preemptive rights of any stockholder of Issuer.

     6.  REPRESENTATIONS AND WARRANTIES OF GRANTEE.  Grantee hereby
represents and warrants to Issuer that:

     (a) Due Authorization.  Grantee has all requisite corporate power and
authority to enter into this Agreement and, subject to any approvals or
consents referred to herein, to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of

<PAGE>

     7.  ADJUSTMENT UPON CHANGES IN ISSUER CAPITALIZATION, ETC. 

     (a) In the event of any change in Issuer Common Stock by reason of a
stock dividend, stock split, split-up, recapitalization, combination, exchange
of shares or similar transaction, the type and number of shares or securities
subject to the Option, and the Purchase Price therefor, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transaction so that Holder shall receive, upon exercise of the Option,
the number and class of shares or other securities or property that Holder
would have received in respect of Issuer Common Stock if the Option had been
exercised immediately prior to such event, or the record date therefor, as
applicable. If any additional shares of Issuer Common Stock are issued after
the date of this Agreement (other than pursuant to an event described in the
first sentence of this subsection (a), upon exercise of any option to purchase
Issuer Common Stock outstanding on the date hereof or upon conversion into
Issuer Common Stock of any convertible security of Issuer outstanding on the
date hereof), the number of shares of Issuer Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 19.9%
of the number of shares of Issuer Common Stock then issued and outstanding,
without giving effect to any shares subject to or issued pursuant to the
Option. No provision of this Section 7 shall be deemed to affect or change, or
constitute authorization for any violation of, any of the covenants or
representations in the Plan.

     (b) In the event that Issuer shall enter in an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one
of its subsidiaries, to merge into Issuer and Issuer shall be the continuing
or surviving corporation, but, in connection with such merger, the then
outstanding shares of Issuer Common Stock shall be changed into or exchanged
for stock or other securities of Issuer or any other person or cash or any
other property or the outstanding shares of Issuer Common Stock immediately
prior to such merger shall after such merger represent less than 50% of the
outstanding shares and share equivalents of the merged company, or (iii) to
sell or otherwise transfer all or substantially all of its assets to any
person, other than Grantee or one of its subsidiaries, then, and in each such
case, the agreement governing such transaction shall make proper provisions so
that the Option shall, upon the consummation of any such transaction and upon
the terms and conditions set forth herein, be converted into, or exchanged
for, an option (the "Substitute Option"), at the election of Holder, of either
(x) the Acquiring Corporation (as hereinafter defined), (y) any person that
controls the Acquiring Corporation, or (z) in the case of a merger described
in clause (ii), Issuer (such person being referred to as "Substitute Option
Issuer"). 

     (c) The Substitute Option shall have the same terms as the Option,
provided, that, if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to Holder. Substitute Option Issuer shall
also enter into an agreement with Holder in substantially the same form as
this Agreement, which shall be applicable to the Substitute Option.  

     (d) The Substitute Option shall be exercisable for such number of shares
of Substitute Common Stock (as hereinafter defined) as is equal to the
Assigned Value (as hereinafter defined) multiplied by the number of shares of
Issuer Common Stock for which the Option was theretofore exercisable, divided
by the Average Price (as hereinafter defined). The exercise price of
Substitute Option per share of Substitute Common Stock (the "Substitute Option
Price") shall then be equal to the Option Price multiplied by a fraction in
which the numerator is the number of shares of Issuer Common Stock for which
the Option was theretofore exercisable and the denominator is the number of
shares of the Substitute Common Stock for which the Substitute Option is
exercisable.

     (e) The following terms have the meanings indicated:

     (1)  "Acquiring Corporation" shall mean (i) the continuing or surviving
corporation of a consolidation or merger with Issuer (if other than Issuer),
(ii) Issuer in a merger in which Issuer is the continuing or surviving person,
or 
<PAGE>
(iii) the transferee of all or substantially all of Issuer's assets (or a
substantial part of the assets of its subsidiaries taken as a whole).

     (2)  "Substitute Common Stock" shall mean the common stock issued by
Substitute Option Issuer upon exercise of the Substitute Option.

     (3)  "Assigned Value" shall mean the highest of (x) the price per share
of Issuer Common Stock at which a Tender Offer or an Exchange Offer therefor
has been made, (y) the price per share of Issuer Common Stock to be paid by
any third party pursuant to an agreement with Issuer, and (z) the highest per
share closing price for shares of Issuer Common Stock within the six-month
period immediately preceding the consolidation, merger, or sale in question.
In the event that a Tender Offer or an Exchange Offer is made for Issuer
Common Stock or an agreement is entered into for a merger or consolidation
involving consideration other than cash, the value of the securities or other
property issuable or deliverable in exchange for Issuer Common Stock shall be
determined by a nationally recognized investment banking firm selected by
Holder or Owner, as the case may be (and if there are both a Holder and an
Owner, the Holder). 

     (4)  "Average Price" shall mean the average closing price per share of
Substitute Common Stock for the one year immediately preceding the
consolidation, merger, or sale in question, but in no event higher than the
closing price of the shares of Substitute Common Stock on the day preceding
such consolidation, merger or sale; provided that if Issuer is the issuer of
the Substitute Option, the Average Price shall be computed with respect to a
share of common stock issued by Issuer, the person merging into Issuer or by
any company which controls such person, as Holder may elect.

     (f) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of Substitute Common Stock outstanding prior to exercise of the
Substitute Option. In the event that the Substitute Option would be
exercisable for more than 19.9% of the aggregate of the shares of Substitute
Common Stock but for the limitation in the first sentence of this subsection
(f), Substitute Option Issuer shall make a cash payment to Holder equal to the
excess of (i) the value of the Substitute Option without giving effect to the
limitation in the first sentence of this subsection (f) over (ii) the value of
the Substitute Option after giving effect to the limitation in the first
sentence of this subsection (f). This difference in value shall be determined
by a nationally-recognized investment banking firm selected by Holder. 

     (g) Issuer shall not enter into any transaction described in subsection
(b) of this Section 7 unless the Acquiring Corporation and any person that
controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder and take all other actions that may be necessary so that the
provisions of this Section 7 are given full force and effect (including,
without limitation, any action that may be necessary so that the holders of
the other shares of common stock issued by Substitute Option Issuer are not
entitled to exercise any rights by reason of the issuance or exercise of the
Substitute Option and the shares of Substitute Common Stock are otherwise in
no way distinguishable from or have lesser economic value (other than any
dimunition in value resulting from the fact that the Substitute Common Stock
are restricted securities, as defined in Rule 144 under the Securities Act)
than other shares of common stock issued by Substitute Option Issuer). 

     8.  REGISTRATION RIGHTS.

     (a) Demand Registration Rights.  Issuer shall, subject to the conditions 
of subparagraph (c) below, if requested by any Holder or Owner, as applicable,
including Grantee and any permitted transferee ("Selling Shareholder"), as
expeditiously as possible prepare and file a registration statement under the
Securities Act if such
<PAGE>
registration is necessary in order to permit the sale or other disposition of
any or all shares of Issuer Common Stock or other securities that have been
acquired by or are issuable to the Selling Shareholder upon exercise of the
Option in accordance with the intended method of sale or other disposition
stated by the Selling Shareholder in such request, including without
limitation a "shelf" registration statement under Rule 415 under the
Securities Act or any successor provision, and Issuer shall use its best
efforts to qualify such shares or other securities for sale under any
applicable state securities laws.  Grantee shall have the right to demand no
more than two registrations pursuant to this paragraph.  If requested by
Grantee in connection with any such registration, Issuer and Grantee shall
provide each other with representatives, warranties, indemnities and other
agreements customarily given in connection with such registration.  If
requested by Grantee in connection with any such registration, Issuer and
Grantee shall become party to any underwriting agreement relating to the sale
of the Option Shares, but only to the extent of obligating themselves in
respect of representations, warranties, indemnities and other agreement
customarily included in such underwriting agreements.

     (b) Additional Registration Rights.  If Issuer at any time after the
exercise of the Option proposes to register any shares of Issuer Common Stock
under the Securities Act in connection with an underwritten public offering of
such Issuer Common Stock, Issuer will promptly give written notice to the
Selling Shareholders of its intention to do so and, upon the written request
of any Selling Shareholder given within 30 days after receipt of any such
notice (which request shall specify the number of shares of Issuer Common
Stock intended to be included in such underwritten public offering by the
Selling Shareholder), Issuer will cause all such shares for which a Selling
Shareholder requests participation in such registration, to be so registered
and included in such underwritten public offering; PROVIDED, HOWEVER, that
Issuer may elect to not cause any such shares to be so registered (i) if the
underwriters in good faith object for valid business reasons, or (ii) in the
case of a registration solely to implement an employee benefit plan or a
registration filed on Form S-4; PROVIDED, FURTHER, HOWEVER, that such election
pursuant to (i) may only be made two times. If some but not all the shares of
Issuer Common Stock, with respect to which Issuer shall have received requests
for registration pursuant to this subsection (b) shall be excluded from such
registration, Issuer shall make appropriate allocation of shares to be
registered among the Selling Shareholders desiring to register their shares
pro rata in the proportion that the number of shares requested to be
registered by each such Selling Shareholder bears to the total number of
shares requested to be registered by all such Selling Shareholders then
desiring to have Issuer Common Stock registered for sale.

     (c) Conditions to Required Registration.  Issuer shall use all reasonable
efforts to cause each registration statement referred to in subparagraph (a)
above to become effective and to obtain all consents or waivers of other
parties which are required therefor and to keep such registration statement
effective, PROVIDED, HOWEVER, that Issuer may delay any registration of Option
Shares required pursuant to subparagraph (a) above for a period not exceeding
180 days provided Issuer shall in good faith determine that any such
registration would adversely affect an offering or contemplated offering of
other securities by Issuer, and Issuer shall not be required to register
Option Shares under the Securities Act pursuant to subsection (a) above:

     (i) prior to the earliest of (a) termination of the Plan pursuant to
Article VII thereof, (b) failure to obtain the requisite stockholder approval
pursuant to Section 6.1.(A) of the Plan, and (c) a Purchase Event or a
Preliminary Purchase Event; 

     (ii)     on more than one occasion during any calendar year; 


     (iii)    within 90 days after the effective date of a registration
referred to in subsection (b) above pursuant to which the Selling Shareholder
or Selling Shareholders concerned were afforded the opportunity to register
such shares under the Securities Act and such shares were registered as
requested; and  

     (iv)     unless a request therefor is made to Issuer by Selling
Shareholders that hold at least 25% or more of the aggregate number of Option
Shares (including shares of Issuer Common Stock issuable upon exercise of the
Option) then
outstanding.
<PAGE>
     In addition to the foregoing, Issuer shall not be required to maintain
the effectiveness of any registration statement after the expiration of nine
months from the effective date of such registration statement. Issuer shall
use all reasonable efforts to make any filings, and take all steps, under all
applicable state securities laws to the extent necessary to permit the sale or
other disposition of the Option Shares so registered in accordance with the
intended method of distribution for such shares, PROVIDED, HOWEVER, that
Issuer shall not be required to consent to general jurisdiction or qualify to
do business in any state where it is not otherwise required to so consent to
such jurisdiction or to so qualify to do business.

     (d) Expenses.  Except where applicable state law prohibits such payments,
Issuer will pay all expenses (including without limitation registration fees,
qualification fees, blue sky fees and expenses (including the fees and
expenses of counsel), legal expenses, including the reasonable fees and
expenses of one counsel to the holders whose Option Shares are being
registered, printing expenses and the costs of special audits or "cold
comfort" letters, expenses of underwriters, excluding discounts and
commissions but including liability insurance if Issuer so desires or the
underwriters so require, and the reasonable fees and expenses of any necessary
special experts) in connection with each registration pursuant to subsection
(a) or (b) above (including the related offerings and sales by holders of
Option Shares) and all other qualifications, notifications or exemptions
pursuant to subsection (a) or (b) above.

     (e) Miscellaneous Reporting.  Issuer shall comply with all reporting
requirements and will do all such other things as may be necessary to permit
the expeditious sale at any time of any Option Shares by the Selling
Shareholders thereof in accordance with and to the extent permitted by any
rule or regulation promulgated by the SEC from time to time, including,
without limitation, Rule 144A. Issuer shall at its expense provide the Selling
Shareholders with any information necessary in connection with the completion
and filing of any reports or forms required to be filed by them under the
Securities Act or the Exchange Act, or required pursuant to any state
securities laws or the rules of any stock exchange. 

     (f) Issuer Taxes.  Issuer will pay all stamp taxes in connection with the
issuance and the sale of the Option Shares and in connection with the exercise
of the Option, and will save the Selling Shareholders harmless, without
limitation as to time, against any and all liabilities, with respect to all
such taxes. 

     9.  QUOTATION; LISTING.  If Issuer Common Stock or any other securities
to be acquired in connection with the exercise of the Option are then
authorized for quotation or trading or listing on the NASDAQ National Market
or any securities exchange, Issuer, upon the request of Holder, will promptly
file an application, if required, to authorize for quotation or trading or
listing the shares of Issuer Common Stock or other securities to be acquired
upon exercise of the Option on the NASDAQ National Market or such other
securities exchange and will use its best efforts to obtain approval, if
required, of such quotation or listing as soon as practicable.

     10. DIVISION OF OPTION.  This Agreement (and the Option granted hereby)
are exchangeable, without expense, at the option of Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer for other
Agreements providing for Options of different denominations entitling the
holder thereof to purchase in the aggregate the same number of shares of
Issuer Common Stock purchasable hereunder. The terms "Agreement" and "Option"
as used herein include any other Agreements and related Options for which this
Agreement (and the Option granted hereby) may be exchanged. Upon receipt by
Issuer of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Agreement, and (in the case of loss, theft
or destruction) of reasonably satisfactory indemnification, and upon surrender
and cancellation of this Agreement, if mutilated, Issuer will execute and
deliver a new Agreement of like tenor and date. Any such new Agreement
executed and delivered shall constitute an additional contractual obligation
on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed
or mutilated shall at any time be enforceable by anyone.
<PAGE>
     11. MISCELLANEOUS.

     (a) Expenses.  Each of the parties hereto shall bear and pay all costs
and expenses incurred by it or on its behalf in connection with the
transactions contemplated hereunder, including fees and expenses of its own
financial consultants, investment bankers, accountants and counsel.
     
     (b) Waiver and Amendment.  Any provision of this Agreement may be waived
at any time by the party that is entitled to the benefits of such provision.
This Agreement may not be modified, amended, altered or supplemented except
upon the execution and delivery of a written agreement executed by the parties
hereto. 

     (c) Entire Agreement: no Third-party Beneficiary;
Severability.  This Agreement, together with the Plan and the other documents
and instruments referred to herein and therein, between Grantee and Issuer (a)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, between the parties with respect to the
subject matter hereof and (b) is not intended to confer upon any person other
than the parties hereto (other than any transferees of the Option Shares or
any permitted transferee of this Agreement pursuant to subsection (h) of this
Section 14) any rights or remedies hereunder. If any term, provision, covenant
or restriction of this Agreement is held by a court of competent jurisdiction
or a federal or state regulatory agency to be invalid, void or unenforceable,
the remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. If for any reason such court or regulatory
agency determines that the Option does not permit Holder or Owner to acquire,
or does not require Issuer to repurchase, the full number of shares of Issuer
Common Stock as provided in Section 3 (as adjusted pursuant to Section 7), it
is the express intention of Issuer to allow Holder or Owner to acquire or to
require Issuer to repurchase such lesser number of shares as may be
permissible without any amendment or modification hereof. 

     (d) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of Washington without regard to any
applicable conflicts of law rules.

     (e) Descriptive Headings.  The descriptive headings contained herein are
for convenience of reference only and shall not affect in any way the meaning

             CHAPTER 13 OF THE WASHINGTON BUSINESS CORPORATION ACT

23B.13.010  Definitions.  As used in this chapter:

     (1) "Corporation" means the issuer of the shares held by a dissenter
before the corporate action, or the surviving or acquiring corporation by
merger or share exchange of that issuer. 

     (2) "Dissenter" means a shareholder who is entitled to dissent from
corporate action under RCW 23B.13.020 and who exercises that right when and in
the manner required by RCW 23B.13.200 through 23B.13.280.

     (3) "Fair value," with respect to a dissenter's shares, means the value
of the shares immediately before the effective date of the corporate action to
which the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

     (4) "Interest" means interest from the effective date of the corporate
action until the date of payment, at the average rate currently paid by the
corporation on its principal bank loans or, if none, at a rate that is fair
and equitable under all the circumstances.

     (5) "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial owner of shares
to the extent of the rights granted by a nominee certificate on file with a
corporation.

     (6) "Beneficial shareholder" means the person who is a beneficial owner
of shares held in a voting trust or by a nominee as the record shareholder.

     (7) "Shareholder" means the record shareholder or the beneficial
shareholder.

23B.13.020  Right to dissent.  (1) A shareholder is entitled to dissent from,
and obtain payment of the fair value of the shareholder's shares in the event
of, any of the following corporate actions:

          (a)  Consummation of a plan of merger to which the corporation is a
party (i) if shareholder approval is required for the merger by RCW
23B.11.030, 23B.11.080, or the articles of incorporation and the shareholder
is entitled to vote on the merger, or (ii) if the corporation is a subsidiary
that is merged with its parent under RCW 23B.11.040;

          (b) Consummation of a plan of share exchange to which the
corporation is a party as the corporation whose shares will be acquired, if
the shareholder is entitled to vote on the plan; 

          (c) Consummation of a sale or exchange of all, or substantially all,
of the property of the corporation other than in the usual and regular course
of business, if the shareholder is entitled to vote on the sale or exchange,
including a sale in dissolution, but not including a sale pursuant to court
order or a sale for cash pursuant to a plan by which all or substantially all
of the net proceeds of the sale will be distributed to the shareholders within
one year after the date of sale;

          (d) An amendment of the articles of incorporation that materially
reduces the number of shares owned by the shareholder to a fraction of a share
if the fractional share so created is to be acquired for cash under RCW
23B.06.040; or

          (e) Any corporate action taken pursuant to a shareholder vote to the
extent the articles of incorporation, bylaws, or a resolution of the board of
directors provides that voting or nonvoting shareholders are entitled to
dissent and obtain payment for their shares.

     (2) A shareholder entitled to dissent and obtain payment for the
shareholder's shares under this chapter may not challenge the corporate action
creating the shareholder's entitlement unless the action fails to comply with
the
<PAGE>
procedural requirements imposed by this title, RCW 25.10.900 through 25.10.955
the articles of incorporation, or the bylaws, or is fraudulent with respect to
the shareholder or the corporation.

     (3) The right of a dissenting shareholder to obtain payment of the fair
value of the shareholder's shares shall terminate upon the occurrence of any
one of the following events:

          (a) The proposed corporate action is abandoned or rescinded;

          (b) A court having jurisdiction permanently enjoins or sets aside
the corporate action; or

          (c) The shareholder's demand for payment is withdrawn with the
written consent of the corporation.

23B.13.030  Dissent by nominees and beneficial owners.  (1) A record
shareholder may assert dissenters' rights as to fewer than all the shares
registered in the shareholder's name only if the shareholder dissents with
respect to all shares beneficially owned by any one person and notifies the
corporation in writing of the name and address of each person on whose behalf
the shareholder asserts dissenters' rights.  The rights of a partial dissenter
under this subsection are determined as if the shares as to which the
dissenter dissents and the dissenter's other shares were registered in the
names of different shareholders.

     (2) A beneficial shareholder may assert dissenters' rights as to shares
held on the beneficial shareholder's behalf only if: 

          (a) The beneficial shareholder submits to the corporation the record
shareholder's written consent to the dissent not later than the time the
beneficial shareholder asserts dissenters' rights; and

          (b) The beneficial shareholder does so with respect to all shares of
which such shareholder is the beneficial shareholder or over which such
shareholder has power to direct the vote. 

23B.13.200  Notice of dissenters' rights.  (1) If proposed corporate action
creating dissenters' rights under RCW 23B.13.020 is submitted to a vote at a
shareholders' meeting, the meeting notice must state that shareholders are or
may be entitled to assert dissenters' rights under this chapter and be
accompanied by a copy of this chapter.

     (2) If corporate action creating dissenters' rights under RCW 23B.13.020
is taken without a vote of shareholders, the corporation, within ten days
after the effective date of such corporate action, shall notify in writing all
shareholders entitled to assert dissenters' rights that the action was taken
and send them the dissenters' notice described in RCW 23B.13.220.

23B.13.210  Notice of intent to demand payment.  (1) If proposed corporate
action creating dissenters' rights under RCW 23B.13.020 is submitted to a vote
at a shareholders' meeting, a shareholder who wishes to assert dissenters'
rights must (a) deliver to the corporation before the vote is taken written
notice of the shareholder's intent to demand payment for the shareholder's
shares if the proposed action is effected, and (b) not vote such shares in
favor of the proposed action.

     (2) A shareholder who does not satisfy the requirements of subsection (1)
of this section is not entitled to payment for the shareholder's shares under
this chapter.

23B.13.220  Dissenters' notice.  (1) If proposed corporate action creating
dissenters' rights under RCW 23B.13.020 is authorized at a shareholders'
meeting, the corporation shall deliver a written dissenters' notice to all
shareholders who satisfied the requirements of RCW 23B.13.210.

     (2) The dissenters' notice must be sent within ten days after the
effective date of the corporate action, and must:
<PAGE>
          (a) State where the payment demand must be sent and where and when
certificates for certificated shares must be deposited; 
      
          (b) Inform holders of uncertificated shares to what extent transfer
of the shares will be restricted after the payment demand is received;

          (c) Supply a form for demanding payment that includes the date of
the first announcement to news media or to shareholders of the terms of the
proposed corporate action and requires that the person asserting dissenters'
rights certify whether or not the person acquired beneficial ownership of the
shares before that date;

          (d) Set a date by which the corporation must receive the payment
demand, which date may not be fewer than thirty nor more than sixty days after
the date the notice in subsection (1) of this section is delivered; and

          (e) Be accompanied by a copy of this chapter.

23B.13.230  Duty to demand payment.  (1) A shareholder sent a dissenters'
notice described in RCW 23B.13.220 must demand payment, certify whether the
shareholder acquired beneficial ownership of the shares before the date
required to be set forth in the dissenters' notice pursuant to RCW
23B.13.220(2)(c), and deposit the shareholder's certificates in accordance
with the terms of the notice.

     (2) The shareholder who demands payment and deposits the shareholder's
share certificates under subsection (1) of this section retains all other
rights of a shareholder until the proposed corporate action is effected.

     (3) A shareholder who does not demand payment or deposit the
shareholder's share certificates where required, each by the date set in the
dissenters' notice, is not entitled to payment for the shareholder's shares
under this chapter.

23B.13.240  Share restrictions.  (1) The corporation may restrict the transfer
of uncertificated shares from the date the demand for their payment is
received until the proposed corporate action is effected or the restriction is
released under RCW 23B.13.260. 

     (2) The person for whom dissenters' rights are asserted as to
uncertificated shares retains all other rights of a shareholder until the
effective date of the proposed corporate action. 

23B.13.250  Payment.  (1) Except as provided in RCW 23B.13.270, within thirty
days of the later of the effective date of the proposed corporate action, or
the date the payment demand is received, the corporation shall pay each
dissenter who complied with RCW 23B.13.230 the amount the corporation
estimates to be the fair value of the shareholder's shares, plus accrued
interest. 

     (2) The payment must be accompanied by:

          (a) The corporation's balance sheet as of the end of a fiscal year
ending not more than sixteen months before the date of payment, an income
statement for that year, a statement of changes in shareholders' equity for
that year, and the latest available interim financial statements, if any;

          (b) An explanation of how the corporation estimated the fair value
of the shares;

          (c) An explanation of how the interest was calculated; 

          (d) A statement of the dissenter's right to demand payment under RCW
23B.13.280; and

          (e) A copy of this chapter.
<PAGE>
23B.13.260  Failure to take action. (1) If the corporation does not effect the
proposed action within sixty days after the date set for demanding payment and
depositing share certificates, the corporation shall return the deposited
certificates and release any transfer restrictions imposed on uncertificated
shares.

     (2) If after returning deposited certificates and releasing transfer
restrictions, the corporation wishes to undertake the proposed action, it must
send a new dissenters' notice under RCW 23B.13.220 and repeat the payment
demand procedure.

23B.13.270  After-acquired shares.  (1) A corporation may elect to withhold
payment required by RCW 23B.13.250 from a dissenter unless the dissenter was
the beneficial owner of the shares before the date set forth in the
dissenters' notice as the date of the first announcement to news media or to
shareholders of the terms of the proposed corporate action.

     (2) To the extent the corporation elects to withhold payment under
subsection (1) of this section, after taking the proposed corporate action, it
shall estimate the fair value of the shares, plus accrued interest, and shall
pay this amount to each dissenter who agrees to accept it in full satisfaction
of the dissenter's demand.  The corporation shall send with its offer an
explanation of how it estimated the fair value of the shares, an explanation
of how the interest was calculated, and a statement of the dissenter's right
to demand payment under RCW 23B.13.280.

23B.13.280  Procedure if shareholder dissatisfied with payment or offer.  (1)
A dissenter may notify the corporation in writing of the dissenter's own
estimate of the fair value of the dissenter's shares and amount of interest
due, and demand payment of the dissenter's estimate, less any payment under
RCW 23B.13.250, or reject the corporation's offer under RCW 23B.13.270 and
demand payment of the dissenter's estimate of the fair value of the
dissenter's shares and interest due, if:

          (a) The dissenter believes that the amount paid under RCW 23B.13.250
or offered under RCW 23B.13.270 is less than the fair value of the dissenter's
shares or that the interest due is incorrectly calculated;

          (b) The corporation fails to make payment under RCW 23B.13.250
within sixty days after the date set for demanding payment; or

          (c) The corporation does not effect the proposed action and does not
return the deposited certificates or release the transfer restrictions imposed
on uncertificated shares within sixty days after the date set for demanding
payment.

     (2) A dissenter waives the right to demand payment under this section
unless the dissenter notifies the corporation of the dissenter's demand in
writing under subsection (1) of this section within thirty days after the
corporation made or offered payment for the dissenter's shares.

23B.13.300  Court action.  (1) If a demand for payment under RCW 23B.13.280
remains unsettled, the corporation shall commence a proceeding within sixty
days after receiving the payment demand and petition the court to determine
the fair value of the shares and accrued interest.  If the corporation does
not commence the proceeding within the sixty-day period, it shall pay each
dissenter whose demand remains unsettled the amount demanded.

     (2) The corporation shall commence the proceeding in the superior court
of the county where a corporation's principal office, or, if none in this
state, its registered office, is located.  If the corporation is a foreign
corporation without a registered office in this state, it shall commence the
proceeding in the county in this state where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
corporation was located.
<PAGE>
     (3) The corporation shall make all dissenters, whether or not residents
of this state, whose demands remain unsettled, parties to the proceeding as in
an action against their shares and all parties must be served with a copy of
the petition.  Nonresidents may be served by registered or certified mail or
by publication as provided by law.

     (4) The corporation may join as a party to the proceeding any shareholder
who claims to be a dissenter but who has not, in the opinion of the
corporation, complied with the provisions of this chapter.  If the court
determines that such shareholder has not complied with the provisions of this
chapter, the shareholder shall be dismissed as a party.

     (5) The jurisdiction of the court in which the proceeding is commenced
under subsection (2) of this section is plenary and exclusive.  The court may
appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value.  The appraisers have the powers
described in the order appointing them, or in any amendment to it.  The
dissenters are entitled to the same discovery rights as parties in other civil
proceedings.

     (6) Each dissenter made a party to the proceeding is entitled to judgment
(a) for the amount, if any, by which the court finds the fair value of the
dissenter's shares, plus interest, exceeds the amount paid by the corporation,
or (b) for the fair value, plus accrued interest, of the dissenter's
after-acquired shares for which the corporation elected to withhold payment
under RCW 23B.13.270.

23B.13.310  Court costs and counsel fees.  (1) The court in a proceeding
commenced under RCW 23B.13.300 shall determine all costs of the proceeding,
including the reasonable compensation and expenses of appraisers appointed by
the court.  The court shall assess the costs against the corporation, except
that the court may assess the costs against all or some of the dissenters, in
amounts the court finds equitable, to the extent the court finds the
dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under RCW 23B.13.280.

     (2) The court may also assess the fees and expenses of counsel and
experts for the respective parties, in amounts the court finds equitable:

          (a) Against the corporation and in favor of any or all dissenters if
the court finds the corporation did not substantially comply with the
requirements of RCW 23B.13.200 through 23B.13.280; or

          (b) Against either the corporation or a dissenter, in favor of any
other party, if the court finds that the party against whom the fees and
expenses are assessed acted arbitrarily, vexatiously, or not in good faith
with respect to the rights provided by chapter 23B.13 RCW.

     (3) If the court finds that the services of counsel for any dissenter
were of substantial benefit to other dissenters similarly situated, and that
the fees for those services should not be assessed against the corporation,
the court may award to these counsel reasonable fees to be paid out of the
amounts awarded the dissenters who were benefitted.

               INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers

     Sections 23B.08.500 through 28B.08.600 of the WBCA contain specific
provisions relating to indemnification of directors and officers of Washington
corporations.  In general, the statute provides that (i) a corporation must
indemnify a director or officer who is wholly successful in his defense of a
proceeding to which he is a party because of his status as such, unless
limited by the articles of incorporation, and (ii) a corporation may indemnify
a director or officer if he is not wholly successful in such defense, if it is
determined as provided in the statute that the director meets a certain
standard of conduct, provided when a director is liable to the corporation,
the corporation may not indemnify him.  The statute also permits a director or
officer of a corporation who is a party to a proceeding to apply to the courts
for indemnification or advance of expenses, unless the articles of
incorporation provide otherwise, and the court may order indemnification or
advance of expenses under certain circumstances set forth in the statute.  The
statute further provides that a corporation may in its articles of
incorporation or bylaws or by resolution provide indemnification in addition
to that provided by the statute, subject to certain conditions set forth in
the statute.

     Pursuant to InterWest's Articles of Incorporation, InterWest will
indemnify the officers, directors, agents and employees of InterWest with
respect to expenses, settlements, judgments and fines in suits in which such
person has made a party by reason of the fact that he or she is or was an
agent of InterWest.  No such indemnification may be given if the acts or
omissions of the person are adjudged to be in violation of law, if such person
is liable to the corporation for an unlawful distribution, or if such person
personally received a benefit to which he or she was not entitled.  

     InterWest's Articles of Incorporation provide that the directors of
InterWest shall not be personally liable for monetary damages to InterWest for
certain breaches of their fiduciary duty as directors, except for liabilities
that involve intentional misconduct by the director, the authorization or
illegal distributions or receipt of an improper personal benefit from their
actions as directors.

  Item 22.  Undertakings

     (a)  (1)  The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933 each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

          (2)  The undersigned registrant hereby undertakes as follows: that
prior to any public reoffering of the securities registered hereunder through
use of a prospectus which is a part of this registration statement, by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.

          (3)  The registrant undertakes that every prospectus:  (i) that is
filed pursuant to the immediately preceding paragraph, or (ii) that purports
to meet the requirements of Section 10(a)(3) of the Securities Act and is used
in connection with an offering of securities subject to Rule 415, will be
filed as a part of an amendment to the registration statement and for the
purpose of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that shall be deemed to be the initial bona fide offering
thereof.

          (4)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions referred to in Item 20 of
this registration statement, or otherwise, the registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.

     (b) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt
of such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

     (c) The undersigned registrant hereby undertakes to supply by means of a
post effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of, and
included in the registration statement when it became effective.

Gentlemen and Lady:

     You have requested our opinion as special counsel for InterWest Bancorp,
Inc., a Washington corporation, in connection with the above-referenced

     In rendering this opinion, we understand that the common stock of
InterWest Bancorp, Inc. will be offered and sold in the manner described in
the Prospectus/Joint Proxy Statement, which is part of the Registration

     Based upon the foregoing, it is our opinion that the shares of common

paid and nonassessable.

     This opinion is furnished for use as an exhibit to the Registration
Statement. We hereby consent to the filing of this opinion as an exhibit to
the Registration Statement and to the reference to us under the heading "Legal
Opinions."

                              Very truly yours,

Board of Directors
InterWest Bancorp, Inc.

Gentlemen and Ladies:

     You have requested our opinions as to the federal income tax consequences
of the proposed merger (the "Merger") of Central Bancorporation ("Central")
with and into InterWest Bancorp, Inc. ("InterWest") pursuant to the Agreement
and Plan of Mergers dated January 10, 1996 by and among InterWest, InterWest

     In issuing the opinions set forth in this letter, we have relied upon (1)
factual representations made by Central in written statements dated

understanding of the facts set forth in the Merger Agreement, the
Representations, and the Registration Statement.  Any change in such facts may
adversely affect our opinions.  Furthermore, as explained below, our opinions
are based upon our understanding of the existing provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), currently applicable
regulations promulgated under the Code, current published administrative
positions of the Internal Revenue Service such as revenue rulings and revenue
procedures, and existing judicial decisions, all of which are subject to
change either prospectively or retroactively.
<PAGE>
     Any change in such authorities may adversely affect our opinions.  We
assume no obligation to update our opinions for any deletions or additions to
or modification of any law applicable to the Merger. 

     Based on our review of the Merger Agreement, the Representations, and the
Registration Statement, and assuming that the transactions described therein
are completed as described, our opinions as to federal income tax consequences
of the Merger are as follows.

     1.   Provided that the Merger qualifies as a statutory merger under the
laws of the state of Washington, the Merger will constitute a reorganization
within the meaning of Sections 368(a)(1)(A) of the Code.  Central and
InterWest will each be a "party to a reorganization" within the meaning of
Section 368(b) of the Code.

     2.   Pursuant to Section 354(a)(1) of the Code, no gain or loss will be
recognized by Central shareholders who exchange all of their Central common
stock solely for shares of InterWest's voting common stock.

     3.   Pursuant to Section 358(a)(1) of the Code, the basis of the
InterWest voting common stock received by those Central shareholders receiving
solely InterWest common stock will be the same, in each instance, as the basis
of the Central common stock surrendered in exchange therefor.

     4.   Pursuant to Section 1223(1) of the Code, the holding period of
InterWest voting common stock received by the Central shareholders will
include, in each instance, the period during which the Central common stock
surrendered in exchange therefor was held, provided the Central common stock
is held as a capital asset in the hands of the Central shareholders on the
date of exchange. 

     5.   Pursuant to Revenue Ruling 66-365, 1966-2 C.B. 116, and Revenue
Procedure 77-41, 1977-2 C.B. 574, if a cash payment is received by a
shareholder of Central in lieu of a fractional share interest of Central
voting stock, the cash payment will be treated as received by the shareholder
as a distribution in redemption of that fractional share interest and will be
treated as a distribution in full payment in exchange for the fractional share
redeemed subject to the provisions and limitations of Section 302 of the Code
and considering the application of Section 318 of the Code.

     We express no opinion with regard to the federal income tax consequences
of the Merger not addressed expressly by the above opinions.  In addition, we
express no opinion as to any state, local or foreign tax consequences with
respect to the Merger.

     This opinion is being furnished only to you in connection with the Merger
and solely for your benefit in connection therewith and may not be used or
relied upon for any other purpose and may not be circulated, quoted or
otherwise referred to for any other purpose without our express written
consent.


     The shareholders of Central should consult with a qualified tax advisor
with respect to any reporting requirements which may be applicable, or to any
tax considerations other than those expressly mentioned herein. 

                                   Very truly yours,
