                                             May 9, 1996



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 the Elks Club,
6431 60th Avenue, N.W., Oak Harbor, Washington on Friday, June 7, 1996 at 2:00
p.m., local time.

           The Notice of Special Meeting of Shareholders and Prospectus/Joint
Proxy Statement that appear on the following pages 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. 
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
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,

/s/ Barney Beeksma                           /s/ Stephen M. Walden

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 June 7, 1996 at 1:30 p.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 $2 0.00 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 April 30,
1996 was $23.88 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, we recommend that you vote FOR
approval of the Merger Agreement.

                           Sincerely,

/s/ Don Wm. Telford                /s/ Gary M. Bolyard

be held on June 7, 1996, and at any adjournments or postponements thereof (the

          This Prospectus/Joint Proxy Statement is also being furnished by

value $1.67 per share ("Central Common Stock"), in connection with the

INTERWEST SPECIAL MEETING

          Place, Time and Date; Purpose.  The InterWest Special Meeting will
be held on Friday, June 7, 1996 at 2:00 p.m., local time, at the Elks Club,

the close of business on April 25, 1996 as the record date (the "InterWest
Record Date") for determining shareholders entitled to notice of and to vote
at the InterWest Special Meeting.  Only those holders of shares 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.  Shareholders who execute proxies

shares entitled to be voted at the InterWest Special Meeting.  All of the
directors and executive officers of InterWest have indicated their intention
to vote their shares for the approval of the Merger Agreement.  See "THE
MEETINGS -- InterWest Special Meeting -- Vote Required."

          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.

CENTRAL ANNUAL MEETING

          Place, Time and Date; Purpose.  The Central Annual Meeting will be
held on Friday, June 7, 1996 at 1:30 p.m., local time at 301 North Chelan,
Wenatchee, Washington, for the purpose of considering and voting upon a
proposal to approve the Merger Agreement attached hereto as Appendix A and

successors have been elected and qualified.  See "THE MEETINGS -- Central
Annual Meeting -- Place, Time and Date" and "-- Purpose."

          Record Date; Shares Entitled to Vote.  The Central Board has fixed
the close of business on April 25, 1996 as the record date (the "Central
Record Date") for determining shareholders entitled to notice of and to vote
at the Central Annual Meeting.  Only those holders of shares of Central Common
Stock of record on the Central Record Date will be entitled to notice of and
to vote at the Central Annual Meeting.  Each share of Central Common Stock
will be entitled to one vote.  Shareholders who execute proxies retain the
right to revoke them at any time prior to being voted at the Central Annual
Meeting.  At the Central Record Date, there were 1,014,565 shares of Central
Common Stock outstanding and entitled to be voted at the Central Annual
Meeting.  See "THE MEETINGS  -- Central Annual Meeting -- Record Date; Shares
Entitled to Vote."

           Vote Required.  Approval of the Merger Agreement requires the
affirmative vote of the holders of two-thirds of the outstanding shares of
Central Common Stock.  At the Central Record Date, the directors and executive
officers of Central and their affiliates beneficially owned 216,773 shares of
Central Common Stock, which represents 21.4% of the shares entitled to be
voted at the Central Annual Meeting.  Simultaneous with the execution of the
Merger Agreement, all of the directors of Central entered into an agreement
with InterWest pursuant to which each director agreed to vote his or her
shares for approval of the Merger 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.  See "THE MEETINGS -- Central Annual Meeting -- Vote Required."
<PAGE>
<PAGE>
          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.

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. 
As a result of the Merger, Central will cease to exist and InterWest will
succeed to all of the assets and liabilities of Central.  See "THE MERGER --
General; Exchange Ratio."  It is currently intended that in connection with
the Merger, NCWB will be merged with CWB, with CWB surviving such merger, and
that after consummation of the Merger, CWB will operate as a wholly-owned
subsidiary of InterWest.

          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.  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."

RECOMMENDATION OF THE INTERWEST BOARD

          The InterWest Board has unanimously approved the Merger Agreement as
advisable and in the best interests of InterWest and the InterWest
shareholders and recommends that the shareholders of InterWest vote FOR

factors considered by the InterWest Board in making its recommendation, see

InterWest's financial advisor, has delivered a written opinion to the
InterWest Board, dated the date of this Prospectus/Joint Proxy Statement, to

"THE MERGER -- Opinions of Financial Advisors -- InterWest."

          Central.  Columbia Financial Advisors, Inc. ("CFA"), Central's
financial advisor, has delivered a written opinion to the Central Board, dated
the date of this Prospectus/Joint Proxy Statement, and a substantially
identical written opinion dated January 10, 1996, to the effect that the terms
of the Merger are fair to Central shareholders from a financial point of view. 
A copy of CFA's opinion, dated the date of this Prospectus/Joint Proxy
Statement, setting forth the assumptions made, matters considered, procedures
followed and limits of its review, is attached hereto as Appendix D and should
be read by shareholders in its entirety.  See "THE MERGER -- Opinions of
Financial Advisors -- Central."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

          Certain members of Central's management and the Central Board may be
deemed to have interests in the Merger in addition to their interests as
shareholders of Central generally.  These include, among other things,
provisions in the Merger Agreement relating to indemnification, employment
agreements, and appointments to the InterWest Board.

          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.

          Following the Effective Time, Gary M. Bolyard, the President and
Chief Executive of Central, and Joseph E. Riordan, the Treasurer, Assistant
Secretary and Chief Financial Officer of Central, will enter into employment
agreements with InterWest and InterWest Savings.  Pursuant to Mr. Bolyard's
agreement, he will serve as Vice Chairman/Commercial Banking from consummation
of the Merger until June 30, 1998.  Mr. Bolyard's base salary under the
agreement will be $132,000.  Pursuant to Mr. Riordan's agreement, he will
serve as a Vice President of InterWest and InterWest Savings for a period of
three years commencing upon the consummation of the Merger.  Mr. Riordan's
base salary under the agreement will be $75,000.

          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 consummation of the Merger and to use its best
efforts to cause the election of such persons at the next annual meeting of
InterWest shareholders.  The other representative of Central is expected to be
Larry Carlson, who is currently on the Central Board.  InterWest has also
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.

<PAGE>
          In addition, pursuant to the terms of Deferred Compensation
Agreements between CWB and six of CWB's directors (who are also directors of
Central), as a result of the Merger, such directors will become entitled to
receive deferred board of directors and committee fees over a ten-year period. 
The aggregate amount of deferred compensation as of December 31, 1995 was
$700,000.

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
<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 is subject to the receipt of certain prior approvals from
the Board of Governors of the Federal Reserve System ("Federal Reserve Board")
and the Department.  An application for approval of the Merger was filed with
the Federal Reserve Board and the Department on May 2, 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." 

          Because certain tax consequences of the Merger may vary depending on
the particular circumstances of each shareholder, each Central shareholder is
urged to consult his or her own tax advisor as to the specific tax
consequences to such holder of the Merger, including the specific application
and effect of state, local, foreign and other tax laws to such shareholder.

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

the rights of shareholders of 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 pro forma condensed combined selected financial data have been
prepared based on a 1.41 Exchange Ratio.  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 than 1.41.  The pro forma information
would be different if the InterWest Price results in an Exchange Ratio
different from 1.41.  Central shareholders are urged to obtain current
quotations of the market price of InterWest Common Stock.  The pro forma
condensed combined selected 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.

          Proposed federal legislation to recapitalize the SAIF would require
savings institutions like InterWest Savings to pay a one- time assessment to
increase the SAIF's reserves to $1.25 per $100 of deposits.  The assessment is
expected to be approximately 80 basis points on the amount of deposits held by
a SAIF-member institution at March 31, 1995.  The payment of a one-time fee
would have the effect of immediately reducing the capital and pre-tax earnings
of SAIF-member institutions by the amount of the fee.  Based on InterWest
Savings' assessable deposits of $838.0 million at March 31, 1995, a one-time
assessment of 80 basis points would equal approximately $6.7 million.  The
possible payment of such assessment has not been reflected in the pro forma
condensed combined selected financial data.

Central 1995 10-KSB accompanying this Prospectus/Joint Proxy Statement.  The
pro forma information has been prepared to illustrate a 1.7 and a 1.41
Exchange Ratio.  The actual Exchange Ratio will depend on the InterWest Price
(which will not be known until shortly before the Effective Date) and may be
different than 1.7 or 1.41.  The pro forma information would be different if
the InterWest Price results in an Exchange Ratio different from 1.7 or 1.41.

                                                 THE MEETINGS

INTERWEST SPECIAL MEETING

          Place, Time and Date.  The InterWest Special Meeting will be held on
Friday, June 7, 1996 at 2:00 p.m., local time, at the Elks Club, 6431 60th
Avenue, N.W., 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 InterWest Special
Meeting.

           Record Date; Shares Entitled to Vote.  The InterWest Board has
fixed the close of business on April 25, 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 6,474,086
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 1,110,731
shares of InterWest Common Stock, which represents 17.2% 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
<PAGE>
<PAGE>
InterWest Special Meeting, a written notice of revocation bearing a later date
than the proxy or a later dated proxy 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.

CENTRAL ANNUAL MEETING

           Place, Time and Date.  The Central Annual Meeting will be held on
Friday, June 7, 1996 at 1:30 p.m., local time, at 301 North Chelan, Wenatchee,
Washington.  This Prospectus/Joint Proxy Statement is being sent to holders of
Central Common Stock and is accompanied by a form of proxy which is being
solicited by the Central Board for use at the Central Annual Meeting and any
adjournments or postponements thereof.

           Purpose.  The purpose of the Central Annual 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 conversion of shares
of Central Common Stock into shares of InterWest Common Stock, (ii) to elect
two directors to serve for a term of three years or until their successors
have been elected and qualified and (iii) to act upon such other matters, if
any, as may properly come before the Central Annual Meeting.

           Record Date; Shares Entitled to Vote.  The Central Board has fixed
the close of business on April 25, 1996 as the Central Record Date for
determining shareholders entitled to notice of and to vote at the Central
Annual Meeting.  Only those holders of Central Common Stock of record on the
Central Record Date will be entitled to notice of and to vote at the Central
Annual Meeting.  Each share of Central Common Stock will be entitled to one
vote.  At the Central Record Date, there were 1,014,565 shares of Central
Common Stock outstanding and entitled to be voted at the Central Annual
Meeting.

           Vote Required.  A majority of the shares entitled to vote,
represented in person or by proxy, will constitute a quorum for the
transaction of business at the Central Annual Meeting.  Abstentions and broker
non-votes 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 two-thirds of the shares of Central Common Stock entitled to
vote at the Central Annual Meeting.  Abstentions and broker non-votes will
have the same 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 of business is present at the Central Annual Meeting.

          At the Central Record Date, the directors and executive officers of
Central and their affiliates beneficially owned an aggregate of 216,773 shares
of Central Common Stock, which represents 21.4% of the shares entitled to be
voted at the Central Annual Meeting.  Simultaneous with the execution of the
Merger Agreement, all of the directors of Central entered into an agreement
PAGE
<PAGE>
with InterWest pursuant to which each director agreed to vote his or 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
to vote in person at the Central Annual Meeting will have the effect of a vote
cast against the Merger Agreement.  If any other matters are properly
presented at the Central Annual Meeting for consideration, including, among
other things, a motion to adjourn the Central Annual 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 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.

           The proxy for the Central Annual Meeting is being solicited on
behalf of the Central Board.  The expense of soliciting proxies for the
Central Annual Meeting will be borne by Central.  The expense of printing this
Prospectus/Joint Proxy Statement is to be shared equally by Central and
InterWest.  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 Central 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 Central Common Stock on behalf of another will be
asked to forward proxy materials and related documents to the beneficial
owners of such stock, and Central will reimburse them for their expenses in
doing so.

                                     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.  The separate existence
of Central will cease upon completion of the Merger.  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."  It is currently intended that
in connection with the Merger, NCWB will be merged with CWB, with CWB
surviving such merger, and that after consummation of the Merger, CWB will
operate as a wholly-owned subsidiary of InterWest.
<PAGE>
<PAGE>
           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 April 30, 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 $23.88.  By way
of example only, if the InterWest Price is also $23.88, each share of that
holder's Central Common Stock would be converted into 1.424 shares of
InterWest Common Stock, which would have a value, determined on the basis of
the InterWest Price, equal to $34.00.  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 third 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
<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 Stock 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 shares of InterWest
Common Stock 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 shares of InterWest Common Stock 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 shares of InterWest Common Stock issued in
the Merger, but no dividend or other distribution payable to the holders of
record of InterWest Common Stock 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. 
Central did not pursue the strategy of growth through acquisition because
after surveying its market area it determined that there were limited
acquisition opportunities.  Central also concluded that reengineering and
consolidation of Central's two subsidiary banks would not provide access to
new markets or provide in-market growth opportunities.  In addition Central
concluded that the cost savings of the consolidation would not be significant
enough to warrant a merger of Central's two subsidiary banks and would not
offer a solution to the illiquidity of Central's Common Stock.  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.
<PAGE>
<PAGE>
           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 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 and because Central desired a
tax-free transaction for its shareholders, 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.  Pursuant to a letter agreement dated as of November 29,1995,
InterWest retained Sandler O'Neill to act as financial advisor to InterWest in
connection with the Merger and to provide a written fairness opinion.  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.  The Exchange Ratio was negotiated on an arm's length basis
between representatives of InterWest and Central with the assistance of
Sandler O'Neill and CFA.  The parties established an exchange ratio of 1.7 so
long as the price of InterWest Common Stock was above $17.00 and below $20.00
per share.  The parties determined that if the price of InterWest Common Stock
exceeded $20.00, Central shareholders would receive $34.00 in value of
InterWest Common Stock for each share of Central Common Stock.  The minimum
exchange ratio of 1.41 was established to ensure that dividend payments to
Central shareholders did not decline after the Merger based on the current
dividend paid by InterWest.

           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 prospects 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 CFA and a report of due diligence
was presented by Central management regarding their findings.  The Central
PAGE
<PAGE>
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; 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 the following factors, which it deemed material: 
(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, which was
desired by Central; (iv) the availability of the pooling of interests method
of accounting, which does not require the recognition of goodwill which must
be written off as a charge against operations over time; (v) the financial
advice provided by Sandler O'Neill, including Sandler O'Neill's opinion that
the Exchange Ratio is fair from a financial point of view; (vi) the terms of
other recent comparable combinations of thrift institutions and thrift holding
companies; and (vii) current industry, economic and market conditions, which
indicated continuing consolidation and increasing competition in the banking
and financial services industries.

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

           *   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 THE SHAREHOLDERS 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 material 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.

           *    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 InterWest in connection with the Merger. 
In connection therewith, at the January 10, 1996 meeting at which the
InterWest 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 Prospectus/Joint Proxy Statement, 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").
<PAGE>
<PAGE>
           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 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.  The stock
trading history of InterWest established the range at which InterWest common
stock traded over the past year.  The analysis indicated that InterWest Common
Stock outperformed the S&P 500 index by approximately 28%, the Nasdaq Banking
Index by approximately 22% and the composite group by approximately 17%.  The
stock trading history of Central showed that Central Common Stock is highly
illiquid and that trades are infrequent.

           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
<PAGE>
<PAGE>
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.  The following
analyses assumes that the merger consideration to be received by Central
shareholders is $34.00 per share.  The balance sheet ratios are calculated
based on Central's September 30, 1995 financial information and the income
statement multiples are calculated based on the quarter annualized and year
ended September 30, 1995.  The merger consideration represents 13.48x
Central's twelve months ended September 30, 1995 earnings and 11.06x Central's
three months annualized earnings.  The median multiple for All Transactions
was 16.14x and for Regional Transactions was 13.85x.  The merger consideration
represents 225.24% of Central's book value.  The median multiple for All
Transactions was 201.00% of book value and for Regional Transactions was
206.00% of book value.  The merger consideration represents 225.24% of
Central's tangible book value, the median multiple for All Transactions was
209.00% of tangible book value and for Regional Transactions was 213.00% of
tangible book value.  The merger consideration represents 19.22% of Central's
total deposits.  The median multiple for All Transactions was 19.88% of total
deposits and for Regional Transactions was 22.72% of total deposits.  The
merger consideration represents 17.04% of Central's total assets.  The median
multiple for All Transactions was 17.10% of total assets and for Regional
Transactions was 20.33% of total assets.  The merger consideration represents
an 11.25% deposit premium for Central's core deposits.  The median deposit
premium for All Transactions was 11.30% of core deposits and for Regional
Transactions was 14.36% of core deposits.

           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.

           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 the 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
PAGE
<PAGE>
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. The projected increase in earnings per share of
InterWest Common Stock in 1997 and the projected tangible book value per share
dilution of InterWest Common Stock at June 30, 1996, is directly related to
the actual Exchange Ratio, which will not be determined until shortly before
the Effective Date.  The increase in earnings per share in 1997 is estimated
to range from approximately 0.87% at the top end of the Exchange Ratio to
approximately 4.85% at the bottom end of the Exchange Ratio.  The dilution to
tangible book value per share is estimated to range from approximately 7.92%
at the top end of the Exchange Ratio to approximately 4.47% at the bottom end
of the Exchange Ratio.  This analysis is dependent upon numerous assumptions
with regard to the financial performance and results of operations of both
companies.  These assumptions were reviewed with management and are assumed to
have been reasonably prepared on bases reflecting the best currently available
estimates and judgements of the respective managements of the respective
future financial performances of InterWest and Central and that such
performances will be achieved.  It was 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 the
Merger will qualify for pooling of interests accounting treatment and that
InterWest will remain as a going concern for all periods relevant to its
analyses.

           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, 1995; (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)
certain financial analyses and forecasts of InterWest prepared by and reviewed
with management of InterWest; (viii) the views of senior management of
InterWest and Central of their respective past and current business
operations, results thereof, financial condition and future prospects; (ix)
the pro forma impact of the Merger on InterWest; (x) 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; (xi) the financial terms of recent
business combinations in the savings institution and banking industries; (xii)
the current market environment generally and the banking environment in
particular; and (xiii) 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 on bases reflecting the best currently available estimates
and judgements of the respective managements of the respective future
<PAGE>
<PAGE>
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.  Sandler O'Neill has in the past
two years provided financial advisory services for InterWest for which it has
received fees totalling approximately $40,000.

           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 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
<PAGE>
<PAGE>
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.

           Comparable Sales Multiples.  CFA 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.  In comparison with the Merger
consideration valued at $28.90 to $34.00, this approach indicates that the
proposed transaction is fair from a financial point of view.

           Transaction Value as a Percentage of Total Assets.  CFA calculated
a range of values for the ratio of the total estimated Merger consideration as
a percentage of Central's total assets as of September 30, 1995 and estimated
<PAGE>
<PAGE>
total assets at June 30, 1996 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 total
estimated Merger consideration based on $28.90 and $34.00 per share results in
a median ratio 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 is 14% and 15%,
respectively.

           Investment Value is sometimes referred to as the income earnings
value.  One investment value method frequently 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.  In comparison with the proposed range of
$28.90 to $34.00 per share which Central shareholders would receive in
InterWest Common Stock depending upon the InterWest Price, the valuation range
determined from the Net Present Value analysis is similar, which supports the
conclusion that the transaction is fair from a financial point of view.

           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 216,773 shares of Central
Common Stock (representing 21.4% 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
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.
<PAGE>
<PAGE>
           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.  See "Election of Central
Directors -- Executive Compensation -- Deferred Compensation and Change in
Control Agreements."

           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.

           Deferred Compensation Agreements.  CWB has entered into Deferred
Compensation Agreements with six of CWB's directors (who are also directors of
Central) which allow the directors, at their option, to defer regular monthly
Board of Directors and Executive Committee fees to be paid upon retirement,
termination of the agreement, or a change in control of CWB.  As a result of
the Merger, such directors will become entitled to payment of the deferred
fees.  Under the terms of the agreements, CWB has agreed to pay the deferred
amounts plus interest over a ten-year period.  The amount of interest paid
will be calculated using the September Federal Home Loan Bank Cost of Funds
Index, which is currently 5.01 percent.  The aggregate amount of deferred
compensation as of December 31, 1995, was $700,000.  CWB has purchased
insurance policies on the lives of these directors as a vehicle to fund the
benefits payable under the agreements.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

           The following is a discussion of the material 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 the material federal income tax consequences of the Merger and
<PAGE>
<PAGE>
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.

           The Merger is expected to qualify as a reorganization under Section
368(a) of the Code.  As parties to a reorganization, neither InterWest nor
Central will recognize gain or loss as a result of the Merger.  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.  Because certain tax consequences of the Merger may vary depending
upon the particular circumstances of each shareholder, each Central
shareholder should consult his or her own tax advisor regarding such
shareholder's specific tax situation and status, including the specific
application and effect of state, local and foreign laws to such shareholder
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
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

           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. The Merger is also subject to the approval of the
Department.  An application for approval of the Merger was filed with the
Federal Reserve Board and the Department on May 2, 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
<PAGE>
<PAGE>
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
<PAGE>
<PAGE>
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.

           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 Annual 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
<PAGE>

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
Annual 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 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 $23.00 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 
PAGE
<PAGE>
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 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 data 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 years 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 1.41 Exchange Ratio.  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 than 1.41.

           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 $900,000 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.  Proposed federal legislation to recapitalize the SAIF
would require savings institutions like InterWest Savings to pay a one-time
assessment to increase SAIF's reserves to $1.25 per $100 of deposits.  The
assessment is expected to be approximately 80 basis points on the amount of
deposits held by a SAIF-member institution at March 31, 1995.  The payment of
a one-time fee would have the effect of immediately reducing the capital and
pre-tax earnings of SAIF-member institutions by the amount of the fee.  Based
on InterWest Savings' assessable deposits of $838.0 million at March 31, 1995,
a one-time assessment of 80 basis points would equal approximately $6.7
million.  The possible payment of such assessment has not been reflected in
the pro forma condensed combined financial statements.

           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
Central 1995 Form 10-KSB accompanying this Prospectus/Joint Proxy Statement.

      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 the three 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 statements of income for InterWest
and Central have been prepared as if the Merger was completed at the beginning
of the periods presented.  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 1,430,537 shares of InterWest
Common Stock in exchange for an aggregate of 1,014,565 shares of Central
Common Stock in connection with the Merger based on an Exchange Ratio of 1.41
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

INTEREST 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 the Department and by the FDIC, its primary federal regulator and
the insurer of its deposits.  InterWest Savings' deposits are insured up to
applicable limits under the SAIF of the FDIC.  InterWest Savings is a
community oriented savings bank which has traditionally offered a variety of
PAGE
<PAGE>
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
InterWest as indicated under "AVAILABLE INFORMATION."

CENTRAL AND THE BANKS

           Central is a bank holding company incorporated under the laws of
the State of Washington and is subject to the BHC Act, which places Central
under the supervision of the Board of Governors of the Federal Reserve System. 
The principal role of Central is to supervise and coordinate the activities of
its wholly owned subsidiary banks, CWB and NCWB.  At December 31, 1995,
Central had consolidated total assets of $203.4 million, total loans and
mortgage backed securities of $137.9 million, total customer deposits of
$179.9 million, and total stockholder equity of $15.9 million.

           The Banks are each state chartered banks regulated by the
Department and by the FDIC.  Generally, customer deposits accounts in the
Banks are insured by the FDIC's Bank Insurance Fund for up to a maximum of
$100,000.  The Banks perform banking services for their customers which are
customary for banks of similar size and character.  Such services include
retail banking services to individuals and small and medium size businesses,
as well as savings accounts, checking accounts, and certificates of deposits. 
The Banks are also active in the consumer and commercial banking business, and
provide individuals and businesses a variety of loan programs including real
estate, commercial and agricultural loans.  CWB conducts its business at six
locations, principally throughout Chelan and, to a lesser degree, Douglas,
Grant and Okanogan Counties.  NCWB conducts its business at four locations
principally throughout Okanogan County.

                    DESCRIPTION OF INTERWEST CAPITAL STOCK

           InterWest is authorized to issue 20,000,000 shares of Common Stock,
$0.20 par value per share.  At the InterWest Record Date, 6,474,086 shares of
InterWest Common Stock were issued and outstanding.  InterWest Common Stock is
listed for trading on the Nasdaq National Market under the symbol "IWBK." 
Each share of InterWest Common Stock has the same relative rights and is
identical in all respects with every other share of InterWest Common Stock. 
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>
<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.

           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>
<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
<PAGE>
<PAGE>
whether to 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 of Central to a Control
<PAGE>
<PAGE>

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

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 provide that the directors and officer-directors of Central
<PAGE>
<PAGE>
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.

(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
<PAGE>
<PAGE>
         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.
<PAGE>
<PAGE>
           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.

<PAGE>
<PAGE>
     (E)  OUTSTANDING STOCK OF THE CONTINUING BANK.  The shares of InterWest
Savings 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 Savings Common Stock, and the holders thereof shall retain
their rights therein.

or waiver of each condition precedent set forth in, and the granting of each
approval (and expiration of any waiting period) required by, Article VI.  If
the Mergers are not consummated in accordance with this Plan on or prior to

                   ARTICLE II.  CONSIDERATION

     2.1  CORPORATE MERGER CONSIDERATION.  Subject to the 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 Effective Date transmittal
PAGE
<PAGE>
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.

           ARTICLE IV.  REPRESENTATIONS AND WARRANTIES

     4.1. THE COMPANY AND THE BANKS REPRESENTATIONS AND WARRANTIES.  Each of
the Company and the Banks hereby represents and warrants to InterWest and
InterWest Savings as follows:

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

     (B)  ORGANIZATION, STANDING AND AUTHORITY.  Each of the Company and its 
Subsidiaries is duly qualified to do business and is in good standing in the
States of the United States and foreign jurisdictions where the failure to be
duly qualified, individually or in the aggregate, is reasonably likely 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
Option Agreement).

     (D)  THE COMPANY SUBSIDIARIES.  The Company has Previously Disclosed in
Schedule 4.1(D) a list of all of its Subsidiaries.  Each of its Subsidiaries
that is a bank is an "insured depository institution" as defined in the
Federal Deposit Insurance Act, as amended, and applicable regulations
thereunder.  No equity securities of any of its Subsidiaries are or may become
required to be issued (other than to the Company or one of its Subsidiaries)
by reason of any Rights with respect thereto.  There are no contracts,
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
applicable, to vote or to dispose of such shares.  All of the shares of
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
deposits of its Subsidiaries that are banks are insured by the Bank Insurance
Fund of the FDIC.

     (E)  CORPORATE POWER.  Each of the Company and its Subsidiaries has the
corporate power and authority to carry on its business as it is now being
conducted and to own all its material properties and assets.
<PAGE>
<PAGE>
     (F)  CORPORATE AUTHORITY.  Subject to any necessary receipt of approval
by its stockholders referred to in Section 6.1, this Plan and the Stock Option
Agreement have been authorized by all necessary corporate action of the
Company and each of its Subsidiaries that is a Party, and each such agreement
is a valid and binding agreement of the Company and such Subsidiaries,
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
except as Previously Disclosed in Schedule 4.1(G), the execution, delivery and
performance of this Plan and the Stock Option Agreement, and the consummation
by the Company and each of its Subsidiaries that is a Party of the
transactions contemplated hereby and 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 the Company or of any of its
Subsidiaries or to which the Company or any of its Subsidiaries or its or
their properties is subject or bound, which breach, violation or default is
reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect on it, (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 to any such agreement, indenture or
instrument, other than any such consent or approval that, if not obtained,
would not be reasonably likely, individually or in the aggregate, to have a
Material Adverse Effect on it.

     (H)  FINANCIAL REPORTS.  Except as Previously Disclosed in Schedule
4.1(H), (i) as to the Company, its Annual Report on Form 10-K for the fiscal
year ended December 31, 1994, and all other documents filed or to be filed
subsequent to December 31, 1994 under Section 13(a), 13(c), 14 or 15(d) of the
Exchange Act, in the form filed with the SEC (in each such case, the "Holding
Company Financial Reports"), and (ii) as to each of the Company's Subsidiaries 
that is a bank, its call report for the fiscal year ended December 31, 1994,

Reports, the "Financial Reports") did not and will not contain any untrue
statement of a material fact or omit to state a material 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 therein, in each case
in accordance with GAAP during the periods involved, except in each case as
may be noted therein, subject to normal and recurring year-end audit
adjustments in the case of unaudited statements.

     (I)  ABSENCE OF UNDISCLOSED LIABILITIES.  Neither the Company nor any of
its Subsidiaries has any obligation or liability (contingent or otherwise)
that, individually or in the aggregate, is reasonably likely to have a
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
December 31, 1994, no event has occurred that, individually or in the
aggregate, is reasonably likely to have a Material Adverse Effect on it.
<PAGE>
<PAGE>
     (K)  PROPERTIES.  Except as reserved against in its Holding Company
Financial Reports, the Company and each of its Subsidiaries have good and
marketable title, free and clear of all liens, encumbrances, charges,
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,
agreement, memorandum of understanding or similar arrangement with, or a
commitment letter or similar submission to, any Regulatory Authority, and
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.

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 ordinances which such
Regulatory Authority enforces, which, as a result of 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

directors or controlling persons) to enter into a cease and desist order,
agreement or memorandum of understanding (or requiring the board of directors
thereof to adopt any resolution or policy);

PAGE
<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 denial of any such favorable
PAGE
<PAGE>
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
PAGE
<PAGE>
any of the 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 before any court, governmental agency or board or other forum in
which the Company or any of its Subsidiaries or any Participation Facility has

Hazardous Material, whether or not occurring at or on a site owned, leased or

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

4.1(Z)(5).

          (6)  To the Company's knowledge, prior to the period of (i)

InterWest Savings is duly qualified to do business and is in good standing in
the States of the United States and foreign jurisdictions where the failure to

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,

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),

governmental permit or license, or agreement, indenture or instrument of

statement of a material fact or omit to state a material 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

requesting (or is considering the appropriateness of issuing or requesting)
any such order, decree, agreement, memorandum or understanding, commitment
letter or similar submission.

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

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

consistent with past practice since September 30, 1995.   Since September 30,

InterWest Savings, and each of InterWest and InterWest Savings hereby
covenants to the Company and the Banks, that:

     5.1. BEST EFFORTS.  Subject to the terms and conditions of this Plan and
to the exercise by its Board of Directors of such Board's fiduciary duties, it
shall use its best efforts in good faith to take, or cause to be taken, all
actions, and to do, or cause to be done, all things necessary, proper or

PAGE
<PAGE>
the Mergers by June 30, 1996 and to otherwise enable consummation of the
transactions contemplated hereby and (in the case of the Company and
InterWest) by the Stock Option Agreement, and shall cooperate fully with the
other Parties to that end (it being understood that any amendments to the
Registration Statement or a resolicitation of proxies as a consequence of an
Acquisition Transaction in which InterWest or any of its subsidiaries is
involved shall not violate this covenant).

     5.2. THE PROXY.  In the case of the Company: it shall promptly assist
InterWest in the preparation of a proxy statement (the "Proxy Statement") to
be mailed to the holders of the Company Common Stock in connection with the

registration statement (the "Registration Statement") with the SEC as provided
in Section 5.8, which shall conform to all applicable legal requirements, and
it shall call a special meeting (the "Meeting") of the holders of Company
Common Stock to be held as soon as practicable for purposes of voting upon the

Registration Statement made in reliance upon, and in conformity with, written
information concerning another Party furnished by or on behalf of such other
Party specifically for use in the Registration Statement.

     5.4. REGISTRATION STATEMENT EFFECTIVENESS.  In the case of InterWest: it
will advise the Company, promptly after InterWest receives notice thereof, of
the time when the Registration Statement has become effective or any
supplement or amendment has been filed, of the issuance of any stop order or
the suspension of the qualification of the InterWest Common Stock for offering
or sale in any jurisdiction, of the initiation or threat of any proceeding for
any such purpose, or of any request by the SEC for the amendment or supplement
of the Registration Statement or for additional information.

InterWest (i) a copy of each material report, schedule and other document
filed by the Company and its Subsidiaries with any Regulatory Authority and 
(ii) all other information concerning the business, properties and personnel
of the Company and its Subsidiaries as InterWest may reasonably request,
provided that no investigation pursuant to this Section 5.6 shall affect or be
deemed to modify or waive any representation or warranty made by the Company
or the Banks in this Plan or the conditions to the obligations of the Company
and the Banks to consummate the transactions contemplated by this Plan; and

          (B)  InterWest will not use any information obtained pursuant to
this Section 5.6 for any purpose unrelated to the consummation of the
transactions contemplated by this Plan and, if this Plan is terminated, will
hold all confidential information and documents obtained pursuant to this
paragraph in confidence (as provided in Section 8.6) unless and until such
PAGE
<PAGE>
time as such 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

(A)).  In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Date), (i)
InterWest shall have the right to assume the defense thereof and InterWest
shall pay all reasonable fees and expenses of such counsel for the Indemnified

one firm of counsel for all Indemnified Parties in any jurisdiction for any
single action, suit or proceeding, (ii) the Indemnified Parties will cooperate
in the defense of any such matter, and (iii) InterWest shall not be liable for
any settlement effected without its prior written consent.

     (C)  If InterWest or any of its successors or assigns shall consolidate

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.

<PAGE>
<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,
PAGE
<PAGE>
exchange or otherwise, of assets or deposits of Issuer or any of its
significant subsidiaries representing in 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>
<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>
<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>
<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 (iii) the transferee of all or substantially all of Issuer's assets (or a 
PAGE
<PAGE>
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
PAGE
<PAGE>
Securities Act if such 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>
<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

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.

     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

     (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

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

agency determines that the Option does not permit Holder or Owner to acquire,

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.

March 6, 1996

Board of Directors
InterWest Bancorp, Inc.
1259 West Pioneer Way
Oak Harbor, WA 98277

Ladies and Gentlemen:

     InterWest Bancorp, Inc. ("InterWest") and Central Bancorporation
("Central") have entered into an Agreement and Plan of Merger dated as January
10, 1996 (the "Agreement") pursuant to which Central will be merged with and
into InterWest with InterWest being the surviving corporation of the merger
(the "Merger").  Pursuant to the Merger, each outstanding share of Central
common stock, par value $1.67 per share (the "Central Shares"), will be
converted into the right to receive from 1.41 to 1.70 shares (the "Exchange
Ratio") of common stock, par value $.20 per share (the "InterWest Shares"), of
InterWest.  The actual Exchange Ratio will be determined based upon the
average of the bid and ask prices per share of all market makers of InterWest
Shares on the NASDAQ Stock Market for the ten trading days beginning on and
including the twentieth trading day immediately preceding the closing date of
the Merger.  The terms and conditions of the Merger are more fully set forth
in the Agreement.  You have requested our opinion as to the fairness, from a
financial point of view, of the Exchange Ratio to the shareholders of
InterWest.

     Sandler O'Neill Corporate Strategies, a division of Sandler O'Neill &
Partners, L.P., as part of its investment banking business is regularly
engaged in the evaluation of financial institutions and their securities in
connection with mergers and acquisitions and other corporate transactions.

     In connection with this opinion we have reviewed, among other things: (i)
the Agreement; (ii) the Stock Option Agreement dated as of January 10, 1996 by
and between InterWest and Central; (iii) a draft of InterWest's and Central's
joint proxy statement for their respective special meetings of shareholders to
consider and vote upon the Agreement; (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 consolidated
audited 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 December 31, 1995; (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 draft Quarterly Report on Form 10-Q for the quarter ended
PAGE
<PAGE>
March 31, 1996 and delivered to Sandler O'Neill on May 3, 1996; (viii)
InterWest's unaudited financial highlights for the quarter ended March 31,
1996 contained in its press release dated April 15, 1996; (ix) certain
financial analyses and forecasts of InterWest prepared by and reviewed with
management of InterWest; (x) the views of senior management of InterWest and
Central of their respective past and current business operations, results
thereof, financial condition and future prospects; (xi) the pro forma impact
of the Merger on InterWest; (xii) the historical reported price and trading
activity for Central Shares and InterWest Shares, 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; (xiii) the financial terms of recent business combinations in
the savings institution and banking industries; (xiv) the current market
environment generally and the banking environment in particular; and (xv) such
other information, financial studies, analyses and investigations and
financial, economic and market criteria as we considered relevant.

     In performing our review, we have assumed and relied upon, without
independent verification, the accuracy and completeness of all the financial
information, analyses and other information reviewed by and discussed with us,
and we 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,
we have assumed that they have been reasonably prepared on bases reflecting
the best currently available estimates and judgments of the respective
managements of the respective future financial performances of InterWest and
Central and that such performances will be achieved.  We have 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.  We have assumed that the
Merger will qualify for pooling of interests accounting treatment and have
further assumed that InterWest will remain as a going concern for all periods
relevant to our analyses and that the conditions precedent in the Agreement
are not waived.

     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof.  Events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion.  We have not undertaken to
reaffirm or revise this opinion or otherwise comment upon events occurring
after the date hereof.

     We have acted as InterWest's financial advisor in connection with the
PAGE
<PAGE>
Merger and will receive a fee for our services, a significant portion of which
is contingent upon consummation of the Merger.  We will also receive a fee for
rendering this opinion.  We have also provided and continue to provide general
financial advisory services for InterWest and have received and will continue
to receive fees for such services.

     In the ordinary course of our business, we may actively trade the equity
securities of InterWest and Central for our own account and for the accounts
of our customers and, accordingly, may at any time hold a long or short
position in such securities.

     Our opinion is directed to the Board of Directors of the Company and does
not constitute a recommendation to any shareholder of the Company as to how
such stockholder should vote at the special meeting of shareholders to
consider and vote upon the Merger.  Our opinion is not to be quoted or
referred to, in whole or in part, in a registration statement, prospectus,
proxy statement or in any other document, nor shall this opinion be used for
any other purposes, without Sandler O'Neill's prior written consent; provided,
however, that we hereby consent to the inclusion of this opinion as an exhibit
to the InterWest's and Central's joint proxy statement dated  May 6, 1996 so
long as the opinion is quoted in full in such proxy statement.

     Based upon and subject to the foregoing, it is our opinion that the
Exchange Ratio is fair, from a financial point of view, to the holders of the
InterWest Shares.

                                   Very truly yours,

                                   /s/ Sandler O'Neill & Partners, L.P.

                  OPINION OF COLUMBIA FINANCIAL ADVISORS, INC.

                               May 6, 1996

Board of Directors
Central Bancorporation
301 North Chelan
Wenatchee, Washington 98801

Members of the Board:

     You have requested our opinion as to the fairness, from a financial point
of view, to the shareholders of Central Bancorporation ("CBWA" or the
"Company"), of the merger consideration to be received by such shareholders
pursuant to the terms of the Merger Agreement and Plan of Merger, dated
January 10, 1996, ("Agreement") between CBWA and InterWest Bancorp, Inc.
("IWBK").

     Pursuant to the Agreement, the Company will be acquired in a transaction
(the "Acquisition") and each issued and outstanding share of the Company
common stock (along with its associated rights) at the effective time of the
Merger (other than (I) shares of holders who are exercising appraisal rights
pursuant to applicable law, and (ii) shares held directly by or indirectly by
CBWA, its parent company or any subsidiary thereof other than shares held in a
fiduciary capacity or in satisfaction of a debt previously contracted) shall
be converted into the right to receive 1.7 shares in IWBK common stock if the
average of the bid and ask price per share of all market makers, as reported
on Bloomberg Financial Markets, of IWBK common stock is $20.00 or less, if the
IWBK price is above $20.00 and less than $24.12, the number of shares in IWBK
common stock based on $34.00 divided by the IWBK price, or 1.41 shares in IWBK
common stock if the IWBK price is equal to or greater than $24.12 (the "Merger
Consideration"), except for fractional shares which will receive a
proportional amount of cash.

     Columbia Financial Advisors, Inc. ("CFAI") as a part of its investment
banking services, is periodically engaged in the valuation of banks and
advises the directors, officers and shareholders of both public and private
banks and thrift institutions with respect to the fairness, from a financial
point of view, of the consideration to be received in transactions such as
that proposed by the Agreement.  CFAI has served as financial advisor to the
management and Board of Directors of CBWA since January 1995.  In that role,
PAGE
<PAGE>
we advised on and participated in negotiations with respect to the Merger 
Agreement.  With particular regard to our qualifications for rendering an
opinion as to the fairness, from a financial point of view, of the
Consideration to be received by holders of the shares from IWBK pursuant to
the Merger, CFAI has advised Washington and Oregon community banks regarding
fairness of capital transactions.  CBWA has agreed to pay CFAI a fee for this
opinion letter.

     In connection with rendering this opinion, we have, among other things:
(i) reviewed the Agreement; (ii) reviewed CBWA's financial and related audited
financial information for the twelve months ended September 30, 1995 including
the Form 10-KSB filed with the U.S. Securities and Exchange Commission; (iii)
reviewed certain internal financial analyses and certain other forecasts for
the Company prepared by and reviewed with the management of the Company; (iv)
conducted interviews with senior management of the Company regarding the past
and current business operations, results thereof, financial condition and
future prospects of the Company; (v) reviewed the current market environment
generally and the banking and thrift environment in particular; (vi) reviewed
the prices paid in certain recent mergers and acquisitions in the banking and
thrift industries on a regional basis; (vii) reviewed IWBK's audited financial
information for the fiscal year ended September 30, 1995; (ix) reviewed the
price ranges and dividend history for IWBK common stock; (x) and reviewed such
other information, studies and analyses and performed such other
investigations and took into account such other matters as we deemed
appropriate.

     In conducting our review and arriving at our opinion we have relied on
the accuracy and completeness of all information supplied or otherwise made
available to us, and we have not independently verified such information nor
have we undertaken an independent appraisal of the assets or liabilities of
the Company.  With respect to the financial forecasts referred to above, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgment of the senior management of
the Company.  This opinion is necessarily based upon circumstances and
conditions as they exist and can be evaluated as of the date of this letter.

     This opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote with
respect to the merger.

     In reliance upon and subject to the foregoing, it is our opinion that, as
of the date hereof, the Merger Consideration to be received by the
shareholders of CBWA pursuant to the Agreement is fair, from a financial point
of view, to the shareholders of CBWA.

     (3) "Fair value," with respect to a dissenter's shares, means the value

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.

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

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

          (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,

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

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

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

PAGE
<PAGE>
the procedural requirements imposed by this title, RCW 25.10.900 through

respect to the shareholder or the corporation.

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

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

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

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

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>
<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.
